Significant metabolic improvement by a water extract of olives: animal and human evidence.

Purpose: Dyslipidemia and impaired glucose metabolism are the main health issues of growing prevalence and significant high healthcare cost, requiring novel prevention and/or therapeutic approaches. Epidemiological and animal studies revealed that olive oil is an important dietary constituent, inducing normolipidemia. However, no studies have specifically investigated the polyphenol-rich water extract of olives (OLWPE), generated during olive oil production.

Estrogen receptor-alpha isoforms are the main estrogen receptors expressed in non-small cell lung carcinoma.

The expression profile of estrogen receptors (ER) in Non-Small Cell Lung Carcinoma (NSCLC) remains contradictory. Here we investigated protein and transcriptome expression of ERα wild type and variants. Tissue Micro-Arrays of 200 cases of NSCLC (paired tumor/non-tumor) were assayed by immunohistochemistry using a panel of ERα antibodies targeting different epitopes (HC20, 6F11, 1D5, ERα36 and ERα17p).

Opioids modulate constitutive B-lymphocyte secretion.

The opioid system plays a major role in immunomodulation, while its action on cells of the immune system may be opioid receptor-mediated or not. Opioid effects on B-lymphocytes are considered as indirect, attributed to an interplay between distinct cell populations. The aim of the present study was to investigate whether opioid agonists (morphine, alpha(S1)-casomorphin and ethylketocyclazocine) may have a direct action on the secretion of antibodies and cytokines by multiple myeloma-derived cell lines and normal CD19+ B-lymphocytes.

Antiproliferative and apoptotic effects of selective phenolic acids on T47D human breast cancer cells: potential mechanisms of action.

Introduction: The oncoprotective role of food-derived polyphenol antioxidants has been described but the implicated mechanisms are not yet clear. In addition to polyphenols, phenolic acids, found at high concentrations in a number of plants, possess antioxidant action. The main phenolic acids found in foods are derivatives of 4-hydroxybenzoic acid and 4-hydroxycinnamic acid.
