Turmeric
Turmeric is referred as the “Queen of Spices”. It is loaded with many health nutrients and wide range of antioxidant and anti-inflammatory properties. This helps ward off dementia and reduce your risk of cancer. These antioxidants also maintain cholesterol levels and slow down the signs of normal aging.
CURCUMA
• Curcumina:• Antitrombotica
• Ipocolesterolemizzante
• Antiossidante
• Antinfiammatoria
• Blocca i tumori: leucemie, colon, seno
• Induce apoptosi e blocca l’angiogenesi
La Piperina (pepe) aumenta di 1000 volte l’assorbimento della Curcumina
CURCUMA LONGA
• Endurance exercise induces IL-6 production from myocytes that is thought to impair intracellular defence mechanisms. Curcumin inhibits NF-κB and activator protein 1, responsible for cytokine transcription, in cell lines. The aim of this study was to investigate the effect of curcumin supplementation on the cytokine and stress responses following 2 h of cycling.

The effect of turmeric (Curcumin) supplementation on cytokine and inflammatory marker
responses following 2 hours of endurance cyclingJoseph N Sciberras1*, Stuart DR Galloway2, Anthony Fenech3, Godfrey Grech5, Claude Farrugia4,Deborah Duca4 and Janet Mifsud3

Dosage for the present study subjects was a single dose of 500 mg of Meriva® curcumin (5 tablets) with midday meal for three days, and then 500 mg ingested just before exercise. Samples for plasma curcumin analysis were taken at the final blood sampling time only in this study, three hours post ingestion to coincide with assessment of post-exercise interleukin response.
Carbohydrate and the cytokine response to 2.5 h of runningS. L. NEHLSEN-CANNARELLA,1 O. R. FAGOAGA,1 D. C. NIEMAN,2 D. A. HENSON,2D. E. BUTTERWORTH,2 R. L. SCHMITT,1 E. M. BAILEY,1 B. J. WARREN,2 A.

This randomized, double-blind, placebo-controlled study was designed to determine the influence of 6% carbohydrate (C) vs. placebo (P) beverage ingestion on cytokine responses (5 total samples over 9 h) to 2.5 h of high-intensity running (76.7 ± 0.4% maximal O2 uptake) by 30 experienced marathon runners.
For interleukin-6 (IL-6), a difference in the pattern of change between groups was found, highlighted by a greater increase in P vs. C immediately postrun (753 vs. 421%) and 1.5 h postrun (193 vs. 86%) [F(4,112) = 3.77,P = 0.006]. For interleukin-1-receptor antagonist (IL-1ra), a difference in the pattern of changebetween groups was found, highlighted by a greater increase in P vs. C 1.5 h postrun (231 vs. 72%) [F(2,50) = 6.38,P = 0.003]. No significant interaction effects were seen for bioactive IL-6 or IL-1β. The immediate postrun plasma glucose concentrations correlated negatively with those of plasma cortisol (r = −0.67, P < 0.001); postrun plasma cortisol (r = 0.70,P < 0.001) and IL-6 levels (r = 0.54,P = 0.003) correlated positively with levels of IL-1ra.
Taken together, the data indicate that carbohydrate ingestion attenuates cytokine levels in the inflammatory cascade in response to heavy exertion.

trasduzione del segnale attraverso IL-1RI e TNFR1. un | le due interleuchina 1 (IL-
agonisti 1 e IL-1 ) del segnale attraverso un recettore associata alla membrana (IL-1RI), che agisce di concerto con l'IL-1 proteina accessoria del recettore ( IL-1RAcP ) per avviare trasduzione del segnale. IL-1ra impedisce l'associazione di IL-1RI e IL-1RAcP. Formazione del complesso IL-1RI / IL-1RAcP, insieme con l'adattatore molecola MyD88 , porta al reclutamento della IL-1 chinasi recettore IRAK e IRAK2, che successivamente reclutare Recettore del fattore di necrosi tumorale (TNFR) Fattore -associated 6 (TRAF6) . Ciò porta all'attivazione di NF B e MAP-chinasi (MAPK) vie di segnalazione attraverso crescita trasformante factor (TGF ) chinasi -activated 1 (TAK1) e TAK1-binding protein (TAB1). Questa catena di eventi determina l'attivazione di fattori di trascrizione nucleare che successivamente indurre l'espressione di molti geni. b | L'attività biologica del fattore di necrosi tumorale (TNF ) è mediata da recettori del TNF 1 (TNFR1) e 2, che formano quando trimeri vincolato dal ligando. Attivazione di TNFR1 porta al reclutamento di TRAF2 / 5, RIP1 e FADD, attraverso la proteina adattatore TRADD . La successiva reclutamento e l'attivazione di caspasi 8 da FADD possono portare all'apoptosi. TRAF2 / 5 e RIP1 portano alla attivazione di NF B 'e AP-1 attraverso l'attivazione di IKK e MAPK. Così, TNF parti diverse vie di segnalazione a valle con IL-1. È importante notare che questa rappresentazione schematica non comprende tutte le informazioni disponibili su questi percorsi, ma serve come una semplice panoramica.
