Randomized Controlled Trial
Brazilian nut consumption by healthy volunteers improves inflammatory parameters.
The aim of this study was to investigate the effect of a single dose of Brazil nuts on the inflammatory markers of healthy individuals. ⋯ The results indicate a long-term decrease in inflammatory markers after a single intake of large portions of Brazil nuts in healthy volunteers. Therefore, the long-term effect of regular Brazil nut consumption on inflammatory markers should be better investigated.

Infusion of 7.2% NaCl/6% Hydroxyethyl Starch 200/0.5 in On-Pump Coronary Artery Bypass Surgery Patients: A Randomized, Single-Blind Pilot Study.
NaCl 7.2%/6% hydroxyethyl starch (HES) 200/0.5 (HSH) has shown its beneficial effects in cardiac surgery and immunomodulatory values in experiment and human studies. However, there is concern regarding detrimental renal effects of chloride and HES in the intensive care setting. ⋯ NaCl 7.2%/6% hydroxyethyl starch 200/0.5 does not lead to the increase in AKI incidence when used for the volume therapy in on-pump coronary artery bypass surgery patients. NaCl 7.2%/6% hydroxyethyl starch 200/0.5 usage enhanced neither tubular injury nor alteration of glomerular filtration. In addition, HSH can reduce the level of the inflammatory mediators after surgery.

Randomized Controlled TrialMelatonin suppresses markers of inflammation and oxidative damage in a human daytime endotoxemia model.
Melatonin used as an exogenous drug has been documented to have potent antioxidant and anti-inflammatory effects in animal model. We aimed to examine the effect of melatonin in an experimental human sepsis model. ⋯ Melatonin administration before endotoxemia resulted in reduction of certain markers of inflammation and oxidative stress. Further studies are needed to clarify the role of melatonin in clinical setting.

Cinnamon may have therapeutic benefits on lipid profile, liver enzymes, insulin resistance, and high-sensitivity C-reactive protein in nonalcoholic fatty liver disease patients.
Nonalcoholic fatty liver disease (NAFLD) is the most prevalent cause of hepatic injury in the world. One of the most important therapeutic strategies for this disease is modulating insulin resistance and oxidative stress. In this study, we investigated the hypothesis that supplementation with cinnamon exerts an insulin sensitizer effect in patients with NAFLD. ⋯ In the treatment group (P < .05), significant decreases in HOMA (Homeostatic Model Assessment) index, FBS (fasting blood glucose), total cholesterol, triglyceride, ALT (alanine aminotransferase), AST (aspartate aminotransferase), GGT (gamma glutamine transpeptidase), and high-sensitivity C-reactive protein were seen, but there was no significant change in serum high-density lipoproteins levels (P = .122). In both groups, low-density lipoproteins decreased significantly (P < .05). In conclusion, the study suggests that taking 1500 mg cinnamon daily may be effective in improving NAFLD characteristics.

Randomized Controlled Trial
Eugenol and carvacrol induce temporally desensitizing patterns of oral irritation and enhance innocuous warmth and noxious heat sensation on the tongue.
Eugenol and carvacrol, from the spices clove and oregano, respectively, are agonists of TRPV3, which is implicated in transduction of warmth and possibly heat pain. We investigated the temporal dynamics of lingual irritation elicited by these agents, and their effects on innocuous warmth and heat pain, using a half-tongue method in human subjects. The irritant sensation elicited by both eugenol and carvacrol decreased across repeated applications at a 1-minute interstimulus interval (self-desensitization) which persisted for at least 10 minutes. ⋯ Eugenol, but not carvacrol, reduced detection of low-threshold mechanical stimuli. Eugenol and carvacrol enhancement of innocuous warmth may involve sensitization of thermal gating of TRPV3 expressed in peripheral warm fibers. The brief heat hyperalgesia following eugenol may involve a TRPV3-mediated enhancement of thermal gating of TRPV1 expressed in lingual polymodal nociceptors.
