Published: 2009Abstract: Cellulosic-pulp-reinforced cement sheets are produced in large scale for more than 25 years. This followed studies that had focused on the fibre and matrixcharacteristics, and on their composite behaviour, solving to a limited extent the problems arising from fibre-matrix incompatibility and deterioration due to alkali attack. Inspite of that, much has yet to be done in terms of providing a material with properties competitive with those of asbestos cement, mainly considering their long termperformances. Current research on cellulose-pulp reinforced cement composites concentrates on evaluating the deterioration mechanisms, the treatment methods and themodelling of the effects of these mechanisms on the physical, mechanical and micro-structural aspects of the material. Interfacial adhesion governs the mechanical behaviourand many physical properties of composites. Therefore, it is a key issue when focusing on durability, since the deterioration mechanisms and the treatment methods exertdirect influences on the fibre-matrix interface. Direct assessment of adhesion strength by pull-out tests on fibres generally shorter than 2 mm in cellulose-cement compositespresents practical difficulties. Also, direct application of the equations derived from the composite's micromechanics to this type of cement composites, as produced by thevacuum-dewatering process, and containing high volume fractions of curly fibres would be problematic. Fortunately, a significant amount of data is available in the literatureregarding the physical and mechanical 'behaviour of cellulose-cement composites of a variety of compositions and produced under similar conditions. This allowsestablishing mutual correlations. This is used as reference framework for the design of the cellulose-cement compositions tested by the authors. The outcomes reveal thisapproach a valuable tool in comparative studies on the mechanical behaviour of cellulose-cement composites dealing with effects of treatment methods, deteriorationmechanisms and processing parameters.Conference Title: 9th International Symposium on Brittle Matrix Composites (BMC-9)Conference Date: OCT 25-28, 2009Conference Location: Warsaw, POLANDSponsor(s): RILEMTimes Cited in Web of Science: 0Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 0ISBN: 978-1-84569-775-4Accession Number: WOS:000320976700008

Abstract: NOVELTY - Application of coating composition (12) to pre-expanded expanded polystyrene beads (EPS) beads comprises pre-expanding particulate EPS rawmaterial to form EPS beads; passing EPS beads through fluid bed dryer; blowing EPS beads through EPS coating system, where EPS beads are coated with functionalcomposition by spraying composition over the EPS beads; and forcing coated EPS beads (21) through rotating sieve (22) for ensuring that beads of predetermined size aretransferred to EPS beads storage unit and for reduced clumping.

USE - Method for application of coating composition to pre-expanded EPS beads for eliminating restrictive gas layer on surface of EPS beads, used for producinglightweight concrete material (claimed) for constructing homes and commercial buildings.

ADVANTAGE - Having EPS beads in concrete mixture creates lighter concrete mixture, more usable in light construction including homes and commercial buildings. Theconcrete mixture weighs 95 ( plus minus ) pounds/cubic foot as compared to regular concrete which weighs 150 pounds/cubic foot. The coating treatment causes the concreteto be attracted to beads. This adds greatly to the strength of panels. The concrete mixture is fire resistant with burn characteristics of asbestos cement, which means that itdoes not contribute to or assist combustion nor is there any form of off-gassing. The coating process allows finished panels to have microscopic air pockets that reduce theadvent of cracking or spalling (flaking of surface layers of concrete) in very cold temperatures. The light-weight concrete mixture enables the creation of uniquely strong andsturdy lightweight concrete used to construct cost-effective homes that are energy-efficient; can withstand wind, fire, flood, earthquake, mold/mildew and pest, suitable for allgeographic regions and climates; and can be transported to construction sites and set into position creating a simplified, light-weight cost-effective concrete structure that willwithstand any climate and weather damage. The concrete can require less effort to make modifications. Windows and doors made from concrete may easily be cut withsimple abrasive saw.

DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:(1) an EPS coating system; and(2) a functional composition for coating EPS particles used toproduce lightweight concrete material, comprising thalocyanine, polyvinyl acetate and polyvinyl alcohol.

Record 8 of 50Inventor(s): BURIAK M PTitle: Lightweight concrete mixture useful in light construction e.g. homes, commercial buildings comprises cement, water, aggregate, and expanded polystyrene beadscoated with composition of phthalocyanine, polyvinyl acetate and polyvinyl alcoholPatent Number: WO2009152617-A1Patent Assignee: VIDABODE GROUP INCAbstract: NOVELTY - A lightweight concrete mixture (A1) comprises cement, water, an aggregate, and expanded polystyrene (EPS) beads (21) coated with either a coatingcomposition (12) comprising phthalocyanine, polyvinyl acetate and polyvinyl alcohol; or a coating composition comprising (parts by volume) polyvinyl acetate (1), methylhydrate (1), water (3) and methyl blue (0.05).

USE - As lightweight concrete mixture useful for making lightweight building material (claimed); for manufacture of pre-cast concrete blocks, panels, or concrete elementsused to construct cost-effective homes; in light construction such as homes and commercial buildings.

ADVANTAGE - The coating composition removes a restrictive gas layer on expanded polystyrene (EPS) beads by adhering to the beads and having a porosity to allow thegas to dissipate, thus can enable a strong attraction and permanent adherence of a material having cementitious properties, such as, concrete, to the EPS beads. The adherenceof concrete to EPS beads creates a mixture that can be pre-cast into panels significantly lighter and sturdier structurally than existing methods allow for. The coating createsdecreased weight and sturdiness in an EPS and concrete mixture, where previous EPS concrete mixtures failed. The concrete mixture weighs about 95 ( plus minus ) poundsper cubic foot as compared to regular concrete which weighs 150 pounds per cubic foot. The coating treatment causes the concrete to be attracted to the beads. This addsgreatly to the strength of the panels. The concrete mixture is fire resistant with the burn characteristics of asbestos cement; it does not contribute to or assist combustion inany way nor is there any form of off-gassing; and the coating process allows finished panels to have microscopic air pockets that reduce the advent of cracking or spalling(flaking of surface layers of the concrete) in very cold temperatures. The lightweight concrete mixture enables the creation of a uniquely strong and sturdy lightweightconcrete. The structural light-weight concrete allows for the creation of pre-cast structural concrete wall and roof panels that can be transported to construction sites and setinto position creating a simplified, light-weight cost-effective concrete structure that withstand any climate and weather damage. The concrete exhibits wood characteristicswhen driving nails or inserting screws. Using the material, there is no need for pilot holes or anchoring required adhering items to panels of concrete; there is reducedcracking or spalling of the surface. The concrete requires less effort to make modifications than regular concrete. Additionally, windows and doors can easily be cut with asimple abrasive saw. The resulting concrete mixture can be a cost-effective structural lightweight concrete that can address the desire for a material which is fire, wind,water/flood, earthquake/seismic, mold/mildew, and pest resistant, suitable for all geographic regions and climates, and the weight of which (96 pcf) is approximately 64% ofthe weight of regular concrete (150 pcf).

DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lightweight building material obtained by curing the lightweight concrete mixture (A1).

The usage of fine glasspowders (<37 mu m) allowed very short sintering treatments, due to the enhanced nucleating activity of glass surfaces. In particular, dense glass ceramics could be producedby direct insertion of pressed glass powders in the furnace at the sintering temperature, followed by rapid cooling at room temperature after a 30 min holding time. Theproposed approach evidences the feasibility of sintered glass ceramics by the fast and economic processes employed for traditional ceramics, with the advantage of superiormechanical properties (bending strength exceeding 100 MPa, Vickers' microhardness exceeding 6 GPa). Like in traditional ceramics, clay and water could be used for theshaping of pressed tiles, thus posing the conditions for massive industrial production.Times Cited in Web of Science: 6Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 4Times Cited in SciELO Citation Index: 0Total Times Cited: 10ISSN: 1743-6753

Its clearance from the lung is faster and, in comparison toamphibole forms of asbestos, chrysotile asbestos fail to accumulate in the lung tissue due to a mechanism involving fibers fragmentation in short pieces. Short exposure tochrysotile has not been associated with any histopathological alteration of lung tissue.Methods: The present work focuses on the association of small chrysotile fibers with interphasic and mitotic human lung cancer cells in culture, using for analyses confocallaser scanning microscopy and 3D reconstructions. The main goal was to perform the analysis of abnormalities in mitosis of fibers-containing cells as well as to quantifynuclear DNA content of treated cells during their recovery in fiber-free culture medium.Results: HK2 cells treated with chrysotile for 48 h and recovered in additional periods of 24, 48 and 72 h in normal medium showed increased frequency of multinucleatedand apoptotic cells. DNA ploidy of the cells submitted to the same chrysotile treatment schedules showed enhanced aneuploidy values. The results were consistent with thehigh frequency of multipolar spindles observed and with the presence of fibers in the intercellular bridge during cytokinesis.Conclusion: The present data show that 48 h chrysotile exposure can cause centrosome amplification, apoptosis and aneuploid cell formation even when long periods ofrecovery were provided. Internalized fibers seem to interact with the chromatin during mitosis, and they could also interfere in cytokinesis, leading to cytokinesis failurewhich forms aneuploid or multinucleated cells with centrosome amplification.Times Cited in Web of Science: 8Times Cited in BIOSIS Citation Index: 8Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 8ISSN: 1471-2407Accession Number: WOS:000257687600002

These innovations hold majorpromises for medicine but, like all human inventions, they also carry potential risks. The task force reached the following conclusions: - Nanotechnology has alreadyengendered considerable therapeutic progress : - In addition to nanoscale devices specifically designed for medical use, the associated increase in computer processing speedand memory capacity has, as in many other fields, led to an impressive series of medical advances in areas such as imaging technology, implanted physiological stimulationand telemedecine. - Nanobiochips are starting to provide rapid, reliable, ultrasensitive and inexpensive diagnostic tests for many molecular markers, sometimes allowingindividually tailored medicine that takes account of each patient's particular characteristics. Highly specific and individually tailored treatments are now available for certaindisorders. Targeted drug delivery by nanometric "cargo vessels" that deliver the active drug substance solely to pathological cells, is already leading to the use of lower drugdoses, especially in oncology, with less toxicity and better tolerability. - Very soon the treatment of disabilities will be transformed by the development of implantedbiosensors, prosthetic human-machine interfaces, and more solid and well-tolerated implanted prosthetic reconstructive materials. - However, as with all technologicaladvances, nanotechnology, and especially its future applications, carries potential risks for the environment, and especially for individuals involved in the manufacture or useof nanoscale devices. Nanotechnology has developed gradually and with no major incidents over the last twenty years, for several reasons : - The most obvious risks can beavoided, based on our experience with air pollution and asbestos. Moreover, the manufacture of nanomaterials requires the near-systematic use of cleanrooms in order toavoid nanocontamination. - This is why manufacturers and users of nanomaterials are normally exposed to very low doses. - As with all substances, the toxicity ofnanomaterials depends largely on their concentration. - Human administration of nanoscale devices is subject to the strict marketing regulations applying to all drugs andimplanted materials, necessitating extensive testing in the laboratory and in the clinical setting. However, occupational medicine is hindered by the lack of regulationsspecifically covering nanotechnology, This is because, contrary to environmental nanoscale pollution, there is no way of reliably detecting nanoscale objects based on theproperties resulting from their nanometric size. An entirely new, robust and reliable metrology remains to be developed, virtually from scratch. Indeed, these devices havesuch varied properties that it is difficult to single out a small number for toxicological research; as a result, toxicologists have so far focused on products that are, in principle,the most risky. Furthermore, the European Union's REACH directive, which would cover this issue, only registered carbon nanotubes on its list of products in May 2008. TheAcademy considers that these gaps must rapidly be filled in order to avoid two contradictory possibilities. The first is a serious and unforeseen adverse effect that wouldoblige the authorities to declare a precautionary moratorium on nanotechnology as a whole.France cannot afford to fall behind in this area, as the social and economic consequences would e disastrous (for fundamental research, patents, jobs, etc.). In the meantime,there is an urgent need for an appropriate health surveillance program.Times Cited in Web of Science: 2Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 2ISSN: 0001-4079Accession Number: WOS:000263282000029

Issue: 6Pages: 784-787DOI: 10.1038/modpathol.2008.56Published: JUN 2008Abstract: Idiopathic pleuroparenchymal fibroelastosis is a rare recently described entity likely to be under- and misdiagnosed, as awareness of this entity is not yetwidespread. We report two cases that show the need to include this disease in the differential diagnosis of patients with predominantly pleural and subpleural fibroticprocesses. The condition is a fibrotic thickening of the pleura and subpleural parenchyma due to elastic fiber proliferation predominantly in the upper lobes. Performingelastic fiber stains routinely in patients with fibrosis of this distribution may, therefore, aid in establishing the diagnosis and differentiating it from usual interstitialpneumonia/idiopathic pulmonary fibrosis. These patients may be prone to the development of secondary spontaneous pneumothoraces and persistent postoperativebronchopleural fistulae. Continued study of newly diagnosed cases may uncover shared characteristics or features helpful in generating an etiologic hypothesis. Only withbetter understanding of this disease can we hope in the future to be able to offer treatments other than supportive care and ultimately lung transplantation, which are the onlytherapeutic options available today.Times Cited in Web of Science: 10Times Cited in BIOSIS Citation Index: 6Times Cited in Chinese Science Citation Database: 1Times Cited in SciELO Citation Index: 0Total Times Cited: 11ISSN: 0893-3952Accession Number: WOS:000256112900019

Lassinanai)Title: The transformation sequence of cement-asbestos slates up to 1200 degrees C and safe recycling of the reaction product in stoneware tile mixturesSource: JOURNAL OF HAZARDOUS MATERIALSVolume: 152Issue: 2Pages: 563-570DOI: 10.1016/j.jhazmat.2007.07.037Published: APR 1 2008Abstract: Cement-asbestos is the main asbestos containing material still found in most of the European countries such as Italy. Man- and weathering-induced degradation ofthe cement-asbestos slates makes them a source of dispersion of asbestos fibres and represents a priority cause of concern. This concern is the main prompt for the actualpolicy of abatement and disposal of asbestos containing materials in controlled wastes. An alternative solution to the disposal in dumping sites is the direct temperature-induced transformation of the cement-asbestos slates into non-hazardous mineral phases. This patented process avoids the stage of mechanical milling of the material beforethe treatment, which improves the reactivity of the materials but may be critical for the dispersion of asbestos fibres in working and life environment. For the first time, thispaper reports the description of the reaction path taking place during the firing of cement-asbestos slates up to the complete transformation temperature, 1200 degrees C. Thereaction sequence was investigated using different experimental techniques such as optical and electron microscopy, in situ and ex situ quali-quantitative X-ray powderdiffraction. The understanding of the complex reaction path is of basic importance for the optimization of industrial heating processes leading to a safe recycling of thetransformed product.For the recycling of asbestos containing materials, the Italian laws require that the product of the crystal chemical transformation of asbestos containing materials must beentirely asbestos-free, and should not contain more than 0.1 wt% fraction of the carcinogenic substances such as cristobalite. Moreover, if fibrous phases other than asbestos(with length to diameter ratio > 3) are found, they must have a geometrical diameter larger than 3 mu m. We have demonstrated that using an interplay of differentexperimental techniques, it is possible to safely verify the complete transformation of asbestos minerals in this temperature-induced process.The product of transformation of cement-asbestos (CATP) has a phase composition similar to that of a natural or a low temperature clinker with the exception of having alarger content of aluminium, iron and magnesium. This product can be safely recycled for the production of stoneware tile mixtures. The addition of 3-5 mass% of CATPdoes not bear significant variations to the standard parameters of white porcelain tile mixtures. (c) 2007 Elsevier B.V.

If inflammation were critical to the disease process, lung pathology woulddemonstrate an influx of inflammatory cells, and that the disease would respond to immunosuppression. Neither is true. The classic pathology does not display substantialinflammation, and no modulation of the immune system is effective as treatment. Recent data suggest that the pathophysiology of the disease is more a product of fibroblastdysfunction than of dysregulated inflammation. The role of inflammation in disease pathogenesis comes from pathology from atypical patients, biologic samples procuredduring exacerbations of the disease, and careful examination of biologic specimens from patients with stable disease. We suggest that inflammation is indeed a critical factorin IPF and propose five potential nontraditional mechanisms for the role of inflammation in the pathogenesis of IPF: the direct inflammatory hypothesis, the matrixhypothesis, the growth factor-receptor hypothesis, the plasticity hypothesis, and the vascular hypothesis. To address these, we review the literature exploring the differencesin pathology, prognosis, and clinical course, as well as the role of cytokines, growth factors, and other mediators of inflammation, and last, the role of matrix and vascularsupply in patients with IPF.Times Cited in Web of Science: 43Times Cited in BIOSIS Citation Index: 35

We have recentlydeveloped a simple dyeing method for detecting chrysotile asbestos in building materials, which involves pretreatment with calcium-chelating agent and dyeing treatmentwith magnesium-chelating organic dyes. In this study, we further developed a method which eliminates dyed asbestos substitutes containing magnesium, potentially presentin building materials. In the new method, post-treatment with formic acid was conducted to dissolve the non-chrysotile asbestos materials in order to delineate dyedchrysotile asbestos. The calcium-masking process was also shown to be an essential process even when the post-treatment was conducted.

The condition can develop inresponse to a large variety of diseases and tissue injury, among them infectious disease, asbestos, drugs, and radiation therapy. There is no efficient treatment to reverseestablished pleural fibrosis. TGF-beta 1 is suspected, even if not proven, as a key cytokine in this process. In this study, we used adenoviral gene transfer of TGF-beta 1 to thepleural mesothelium in rats. We show that local and transient TGF-beta 1 overexpression induces homogenous, prolonged, and progressive pleural fibrosis withoutpleurodesis, associated with severe impairment of pulmonary function. We further demonstrate that pleural fibrosis can expand into the lung parenchyma from the viscerallayer, but not into the muscle from the parietal layer. We provide evidence that matrix accumulation and fibrosis within the parenchyma evolved through a process involving"mesothelial-fibroblastoid transformation" and suggest that the pleural mesothelial cell may be an important player involved in the development of the subpleural distributionpattern known to be a hallmark of pulmonary fibrosis. This new model of pleural fibrosis will allow us to better understand the mechanisms of progressive fibrogenesis, andto explore novel antifibrotic therapies in the pleural cavity.Times Cited in Web of Science: 33Times Cited in BIOSIS Citation Index: 25Times Cited in Chinese Science Citation Database: 2Times Cited in SciELO Citation Index: 0Total Times Cited: 35ISSN: 0022-1767Accession Number: WOS:000250388000049

Methods: The impact of ASA at workplaces was studied byquestionnaires mailed to 1448 work departments, which were notified to ASA in 1996, and to 1033 departments, which departed ASA in 1991-1996. The mailing wasresponded by 69% of departments. The cancer incidence of 35 138 workers notified to ASA in 1979-1988 was followed up through the files of the Finnish Cancer Registerfor the period 1980-2003. Results: Changes eliminating or substantially reducing exposure to carcinogens were reported by 73% of departments notified to ASA in 1996. TheASA notification process had directly prompted measures to reduce exposure (8% of cases) or contributed to them (24% of cases). Estimations based on responses of theworkplaces suggested that the ASA registration had decreased exposure of 600 workers year(-1) (out of similar to 15 000 notified workers, which is <1% of the employed inFinland), preventing thereby an unknown number of occupational cancers. Other benefits of ASA included the saving of the treatment costs of prevented cancers, theprevention of other health outcomes of carcinogens, improved safety behaviour of exposed workers and avoidance of human suffering among cancer patients and theirfamilies. The tabour safety authorities had better possibilities to direct their activities against carcinogen exposure. These benefits should be considered against the annualcosts, mainly due to 7-8 person-years of work required by tasks related to ASA. The results of the cancer incidence study among notified workers were based on a relativelyshort follow-up (on average 19 years). The incidence of mesothelioma was significantly increased in the ASA cohort, probably due to exposure to asbestos. Conclusions:These results suggest that a national exposure register may stimulate preventive measures at workplaces. Partially based on the results of the present study the FinnishMinistry of Social Affairs and Health continues ASA registration.Times Cited in Web of Science: 6Times Cited in BIOSIS Citation Index: 3Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 6ISSN: 0003-4878Accession Number: WOS:000249763200004

DOI: 10.4103/1817-1737.33704Published: 2007-JulAbstract: BACKGROUND: New information is available on pleural diseases. The authors selected articles to make recommendations on diagnostic and treatment aspects ofpleural diseases.MATERIALS AND METHODS: Eleven articles published in the English language between 2004 and 2007 were chosen. The basis of selection of the articles was the impacton daily practice, change in prior thinking of a disease process or specific treatment modality, as well as proper design and execution of the study. 5-Amino-laevulinic acidwith fluorescent light combined with white light may allow further diagnostic yield in undiagnosed pleural disease. FDG-PET may allow prognostication of patients withpleural tumors. Utilizing ultrasound by trained Emergency Department physicians is a rapid and effective technique to evaluate non-traumatic pleural effusions insymptomatic patients. Serum osteopontin levels may distinguish patients exposed to asbestos with benign disease from those with pleural mesothelioma. Administration ofstreptokinase in patients with empyema does not need for surgical drainage, length of hospital stay, or mortality as compared to conventional treatment with chest tubedrainage and intravenous antibiotics. Silver nitrate may be an alternative agent to talc for producing pleurodesis. Routine use of graded talc (50% particles greater than 25microns) is recommended to reduce the morbidity associated with talc pleurodesis. Study design does not permit us to conclude that aspiration of spontaneous pneumothoraxis as effective as chest tube drainage. Pleural catheter may prove to be an important palliative modality in treating debilitated patients or patients with trapped lung who showsymptomatic improvement with drainage; however, at the present time, these catheters cannot be considered a first line treatment option for patients with malignant pleuraleffusion. One of the studies reviewed showed no significant difference in tract metastasis in patients with malignant mesothelioma undergoing an invasive pleural procedurewith or without irradiation to the procedure site. However, the design of the trial does not allow us to make this conclusion at the present time.Times Cited in Web of Science: 1Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 1ISSN: 1817-1737Accession Number: MEDLINE:19727362

A higher catalytic efficiency wasobtained than the reported values for TiO2 under the same conditions. Chrysotile, a clay mineral fibre of low cost and relatively abundant, probably acts as a catalyst throughan Advanced Oxidative Process (AOP) involving free radical formation. In this work, experiments with non-ionic - Triton X-45 (octil-phenoxy polyethoxy ethanol) - andcationic - Herquat 3500 (alkyl dimethyl benzyl ammonium chloride) - surfactants were carried out. Diluted aqueous solutions (50 ppm) of these surfactants were kept incontact with chrysotile (4.0 g) in the dark at room temperature. The aromatic ring disappearance was followed through the absorbance peaks at 224 nin (Triton X-45) and 208nin (Herquat 3500) in the UV spectra. After 4 h, reductions in the surfactant solution concentration of 65.0% and 35.0% were observed for the Triton X-45 and the Herquat3500 surfactants, respectively. In both cases, reactions carried out without aeration showed a lower reduction of the aromatic ring concentration (30.0% less) when comparedto the values obtained for the systems with airflow. The system containing the non-ionic surfactant seems to achieve equilibrium after 2 It, what is not observed for thecationic surfactant system.Times Cited in Web of Science: 3Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 1Total Times Cited: 3ISSN: 1863-0650Accession Number: WOS:000245284500019

Various techniques have been used inthe production of brake lining. These phenolic composites were subjected to friction and wear tests under different loads, and changes in the hardness and microstructureswere examined.Findings - As a result of this study, the following findings are reported. It was not found a direct proportionality between hardness and wear resistance due to the complexityof composite structure. Heat treatment application changed the microstructure of the brake lining, and increased the hardness and also decreased the density. With theincreasing of temperature, the ingredients in the braking pad were affected other due to faster diffusion. On the other hand, hardness of specimen increases due to heattreatment and also specific wear ratio changes. As a filling material, barite was used due to better performance in the environmental conditions. More wear was observed inthe bigger powder particles comparing to the smaller ones due to more structural loss. Squealing was heard in fiber un-reinforced brake lining due to more barite content Inthe present samples, boric acid deports the water and establishing the structural equilibrium. Therefore, these samples supplied higher and stable friction of coefficient. Also,heat treatment supplied a stable friction coefficient. With the increasing of copper powder into specimens, friction coefficient also increased. Heat treatment made theincrement of hardness of specimens and also it made effect on the hardness with strengthening bonds of interparticles.Research limitations/implications - Limitations in the present research are as follows: two different pressures and eight different temperatures were used and brake liningswere subjected to wear test, hardness tests, microstructures were examined.Practical implications - For future work, instead of buying expensive brake lining, new and cheaper phenolic linings are produced. By this process, economic benefit can begained and also environmental protection can be succeeded in producing such asbestos free brake linings.Originality/value - This paper fulfills an identified information and offers practical help to the industrial firms working with brake lining and also to the academiciansworking on wear of materials.Times Cited in Web of Science: 4

For its early stage, pleurectomy withperioperative treatment can reduce morbidity and mortality. The diagnosis is based on a visual investigation of CT images, which is a time-consuming and subjectiveprocedure. Our aim is to develop an automatic image processing approach to detect and quantitatively assess pleural thickenings.Methods. We first segment the lung areas, and identify the pleural contours. A convexity model is then used together with a Hounsfield unit threshold to detect pleuralthickenings. The assessment of the detected pleural thickenings is based on a spline-based model of the healthy pleura.Results. Tests were carried out on 14 data sets from three patients. In all cases, pleural contours were reliably identified, and pleural thickenings detected. PC-basedComputation times were 85 min for a data set of 716 slices, 35 min for 401 slices, and 4 min for 75 slices, resulting in an average computation time of about 5.2 s per slice.Visualizations of pleurae and detected thickenings were provided.Conclusion: Results obtained so for indicate that our approach is able to assist physicians in the tedious task of finding and quantifying pleural thickenings in CT data. In thenext step, our system will undergo an evaluation in a clinical test setting using routine CT data to quantify its performance.Times Cited in Web of Science: 8Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 8ISSN: 0026-1270Accession Number: WOS:000246545300012

Data were collected from multiple sources that included public testimonies, observations, public hearings and meetingsminutes, newspaper articles, archived records obtained from federal and state environmental and health agencies, as well as industry records obtained through Freedom ofInformation Act (FOIA) requests.FINDINGS: The overarching theme that emerged was lack of trust due to several critical events and factors such as no response or delay in response time to communityconcerns, lack of transparency, perceived cover up, vague and fragmented communication by government and state officials, perception of pro-industry stance, and perceivedunfair treatment.DISCUSSION AND CONCLUSION: People's perception of environmental risks and their willingness to accept official explanations and outcomes of environmentalinvestigations are strongly affected by their direct experiences with government agencies and the evidence of influence the powerful industries exert over relevantinvestigations. The government cannot successfully address public and community concerns about environmental health impacts of contaminations and in turn the publicperception of risk unless it adopts and implements policies, procedures, and protocols that are clear, timely, transparent, and free from industry influence.Times Cited in Web of Science: 1Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 1ISSN: 1048-2911Accession Number: MEDLINE:18184626

Abstract: It is legally demanded that the wastes containing asbestos should be change to harmless substances completely due to the harmful effects of asbestos fiber onhealth. The purpose of present research was to construct a safe, reliable and facile technique by using mechano-chemical reaction, which is a non-combustion process andoperated in a closed system. It was confirmed that the needle crystal of chrysotile asbestos was changed perfectly to amorphous state after grinding by using a planetary ballmill. Furthermore, these products could be remade to useful materials by addition of soil which consists of inorganic materials based on CaO and so one. After the obtainedfine powders were mixed with water, pressed and held under the humid condition, the stable hydrates were found in these products after XRD analysis. These inorganiccompounds were much useful as a new raw material for cement-like.Conference Title: 6th Pacific Rim International Conference on Advanced Materials and ProcessingConference Date: NOV 05-09, 2007Conference Location: Cheju Isl, SOUTH KOREASponsor(s): Korean Inst Met & Mat; Chinese Soc Met; Japan Inst Met; Minerals, Met & Mat Soc; Inst Mat Engn AustraliaTimes Cited in Web of Science: 0Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 0ISSN: 0255-5476ISBN: *****************Accession Number: WOS:000252473302148

The final 100 microg/ml crocidolite concentration and lOnM of epidermalgrowth factor were cocultured with BEAS-2B cells for 30 minutes and 120 minutes. Phosphorylated ERKl/2 and MEKl/2 were detected by Western Blotting using specificantibodies.RESULTS: A rapid phosphorylation expression of ERK1/2 (molecular weight at 44 kD and 42 kD, also called as p44 and p42) was observed by treatment of the BEAS-2Bcells with 100 microg/ml crocidolite or 100 ng/ml EGF (the proven activator of the ERK signaling pathway) at 30 minutes. This phosphorylation could be still detected byincubation the cells at 2 hours. However no expression was changed for the total ERKl/2 expression at 30 minutes or 120 minutes. Treatment of BEAS cells with 100microg/ml crocidolite fiber or 100 ng/ml EGF led to the rapid increased phosphorylation of MEK1/2 at 30 minutes; similarly, the overexpression of MEK1/2 could last 2hours.CONCLUSION: The crocidolite induces the MAPK (ERK1/2 and MEK1/2) phosphorylation within a shorter time. It indicates that the MAPKs signals are involved in theprocess of crocidolite induced damage.Times Cited in Web of Science: 0Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 0ISSN: 1001-9391Accession Number: MEDLINE:17096943

Title: Polyacrylamide induced flocculation of a cement suspensionSource: CHEMICAL ENGINEERING SCIENCEVolume: 61Issue: 8Pages: 2522-2532DOI: 10.1016/j.ces.2005.11.013Published: APR 2006Abstract: The use of cellulose, instead of asbestos, in the fibre cement composites manufacture, using the Hatschek process, reduces cement retention and makes necessaryto use a flocculant which is crucial for the plant productivity. The use of different types and doses of polyacrylamides (PAM) as well as the addition process, have beenstudied to obtain an in-depth knowledge of floc properties. A real-time methodology has been used to study size, shape, strength and reversibility of formed floes, based on afocused beam reflectance measurement (FBRM) system. The results have been corroborated by particle vision and measurement (PVM) analysis. This paper shows thatanionic PAM (A-PAM) are the most suitable to induce cement flocculation and to obtain optimal properties of the formed floes. This is because the flocculation process isenhanced by the interaction of the Ca2+ ions, produced by the cement hydration, with the carboxylic groups of the polymer chains. Cations not only increase the stiffness ofthe chains, improving floc strength, they also enhance the importance of the patching aggregation mechanism when the initial bridges are broken. Higher molecular weightpolymers improve initial aggregation but the effect of anionic charge is more important for a stable flocculation with time under variable shear conditions. Results show thatthe optimal dosage is between 100 and 200 ppm. (c) 2005 Elsevier Ltd.

Advanced breast carcinoma almost always leads to a malignant pleural effusion, conditioning the performance status of patients andconsequently quality of life. The treatment of malignant pleural effusion should be a priority in the management of such patients. The results of videothoracoscopic approach(VATS) chemical pleurodesis was analyzed in patients with recurrent pleural effusion from breast carcinoma.METHODS. From October 1998 to June 2004, 71 consecutive patients with breast carcinoma-related pleural effusion were treated by the same thoracic-surgeon team withintracavitary nebulization of 8 g of asbestos-free sterilized talc via VATS. Multiple pleural biopsies were performed to determine biologic characteristics of recurrent disease.RESULTS, Talc pleurodesis was performed in all cases, with no intraoperative or postoperative complications. Median length of hospital stay was 5 days (range, 5-8). Theoverall success rate of the surgical procedure was 89% (confidence interval [CI], 79-95%) with a mean follow-up of 22 months (range, 2-81 mos). The overall survival timewas 17 months (range, 2-80). Biopsies showed a switch on receptor status and c-erB-2 status from negative (primary tumor) to positive (pleural metastasis) in 11 (15%)patients. In another 7 (9.8%) patients, we obtained completely new information that was hitherto unknown.CONCLUSION. Talc pleurodesis via VATS is an effective and safe procedure that yields a high rate of success at the first attempt and achieves long-term control ofmalignant pleural effusion due to breast carcinoma. Concomitant biopsies performed during the VATS procedure were a determining factor in the Subsequent decision-making process.Times Cited in Web of Science: 13Times Cited in BIOSIS Citation Index: 4Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 13ISSN: 0008-543XAccession Number: WOS:000234588700004

The dehydration reaction of asbestos occurred at 600 degrees Cand has been completed for 2 h at that temperature. This dehydration reaction of asbestos led to weakening of the mechanical properties of asbestos. After grinding, themicrostructure of asbestos appeared no acicular shape. Further, this technique could be applied to asbestos-containing cement board. The spent cement board has about 10-20mass% of asbestos (chrysotile: Mg3Si2O5(OH)(4)) and 5 mm thickness was used. After heating at 600 degrees C for 2 h and grinding, the microstructure of the sample alsoappeared no acicular shape. Thus it was cleared that heating at 600 degrees C and then grinding treatment for asbestos (chrysotile) has a grate important effect of mechanicaland chemical destruction of asbestos in both cases of free asbestos and asbestos-containing cement board.Conference Title: Asian International Conference on Advanced MaterialsConference Date: NOV 03-05, 2005Conference Location: Beijing, PEOPLES R CHINASponsor(s): Nagoya Inst Technol; Nagoya Univ Technol; Beijing Univ Chem Technol; Tsinghua UnivTimes Cited in Web of Science: 0Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 0ISSN: 1022-6680ISBN: 0-87849-407-3Accession Number: WOS:000238490900021

Because MPM is refractory to conventional chemotherapy and radiotherapy, the prognosis of MPM patients is extremely poor. MYO18B,a novel member of the myosin family, is a tumor suppressor gene isolated from a homozygously deleted region at 22q12.1 in a lung cancer cell line. The inactivation of theMYO18B gene plays an important role in several malignant diseases. However, the role of MY018B in the progression of MPM is still unknown. Six different human MTMcell lines were used in this study. Western blot revealed that none of the cell lines expressed a detectable level of MY018B protein. One of the MPM cell lines, EHMES-10,was transfected with the MY018B gene. We found that a restored expression of the MY018B protein in EHMES-10 cells resulted in the inhibition of their anchorage-independent growth and motility in vitro. In addition, it also inhibited their ectopic (subcutaneous space) and orthotopic (thoracic cavity) growth in SCID mice, in associationwith an increased degree of cell apoptosis. Furthermore, it also suppressed the production of bloody pleural effusion after orthotopic injection. These findings suggest that therestored expression of MY018B may be a useful therapeutic strategy for the treatment of locally advanced MPM in humans.Times Cited in Web of Science: 3Times Cited in BIOSIS Citation Index: 2Times Cited in Chinese Science Citation Database: 1Times Cited in SciELO Citation Index: 0Total Times Cited: 4ISSN: 0965-0407Accession Number: WOS:000243540800004

Abstract: Industrial fibrous dusts are applied in many industrial branches and represent adverse factors in occupational and environmental area. Refractory ceramic fibers(RCFs) - amorphous alumina silicates - are used as one kind of asbestos substitutes. Because RCFs are relatively durable and some RCFs are respirable, they may present apotential health hazard by inhalation. The aim of present work was to find out the subchronic effect of RCFs on selected parameters of bronchoalveolar lavage (BAL) inW-rats, confirm the biopersistence of RCFs after 6 month instillation and contribute to the understanding of the pathomechanism of lung injury after fibrous dust exposure.Wistar rats were intratracheally instilled with 4 mg/animal of RCFs - exposed group and with 0.4 ml saline solution/animal - control group. Animals were sacrificed after 6month exposure. Bronchoalveolar lavage (BAL) was performed and selected BAL parameters (mainly inflammatory and cytotoxic) were examined. After treatment withRCFs the following changes were observed: statistically significant increase in proportion of lymphocytes and polymorphonuclears as well as in % of immature alveolarmacrophages (AM) and phagocytic activity of AM; statistically significant decrease in viability of AM and proportion of AM (from the differential cell count) in comparisonwith the control group. The results of this study indicated that RCFs even 6 months after intratracheal instillation very significantly changed the majority of examined BALparameters. The presence of inflammatory and cytotoxic response in lung may signalize beginning or developing disease process.Times Cited in Web of Science: 1Times Cited in BIOSIS Citation Index: 0Times Cited in Chinese Science Citation Database: 0Times Cited in SciELO Citation Index: 0Total Times Cited: 1ISSN: 1213-8118Accession Number: MEDLINE:16601790
