Berry fruits are a rich source of polyphenols, especially anthocyanins: well-known potent anti-oxidant phytochemicals. The purpose of this study was to evaluate beneficial effects of long-term consumption of polyphenol-rich organic chokeberry juice on different markers of antioxidant/pro-oxidant status in healthy female volunteers. Twenty-nine women, aged 25–49, were included in the study. Serological markers of oxidative stress and antioxidant defence, blood pressure, routine biochemical, and anthropometric parameters were analyzed at baseline and after twelve weeks of regular chokeberry juice consumption. Significant decrease in thiobarbituric acid-reactive substances level (TBARS; P < .001) and pro-oxidantantioxidant balance (PAB; P < .05), as well as increase in paroxonase-1 activity toward diazoxon (P < .01) were found. Total oxidative status and sulphydryl groups levels were not significantly influenced by the intervention. Anthropometric, biochemical parameters, and blood pressure values were within the referent values for all subjects and were not influenced by the chokeberry juice consumption. However, we found positive correlation between age, body mass index, waist circumference, body fat percent, blood pressure, and analyzed marker of lipid peroxidation, which was influenced by the consumption. In conclusion, the fine modulation of several antioxidant/pro-oxidant status biomarkers observed in healthy subjects indicates putative prophylactic effects of polyphenol-rich chokeberry juice and supports its importance as part of an optimal diet.

Adiponectin is an adipocyte-derived plasma protein with insulin-sensitizing and anti-inflammatory properties and is suggested to be a biomarker of metabolic disturbances. The aim of this study was to investigate the effects of alpha-lipoic acid (ALA) on plasma adiponectin and some metabolic risk factors in patients with schizophrenia. The plasma adipokine levels (adiponectin and leptin), routine biochemical and anthropometric parameters, markers of oxidative stress, and the serum phospholipid fatty acid profile in eighteen schizophrenic patients at baseline, in the middle, and at the end of a 3-month long supplementation period with ALA (500 mg daily) were determined. A significant increase in the plasma adiponectin concentrations, as well as a decrease in fasting glucose and aspartate aminotransferase activity (AST), was found. Baseline AST activity was independently correlated with the adiponectin concentrations. Our data show that ALA can improve plasma adiponectin levels and may play a potential role in the treatment of metabolic risk factor in patients with schizophrenia. Future randomized controlled trials are needed to confirm these preliminary investigations.

In this letter, a wireless communication system with microdiversity and macrodiversity reception in gamma-shadowed Rician fading channels is considered. Exact and rapidly converging infinite-series expressions for the average level crossing rate and average fade duration at the output of the system are provided. Numerical results are presented graphically to illustrate the proposed mathematical analysis and to examine the effects of the system’s parameters on the quantities considered.

Gastrointestinal metastases from invasive lobular breast cancer are uncommon with the stomach and small intestines being the most common metastatic sites. Peritoneal and rectal metastases are very rare and only rarely occur as the first manifestation of disease. We herein report the case of a 47-year-old woman who presented with abdominal carcinomatosis as a first sign of invasive lobular breast carcinoma (ILC). Identifying the most important immunohistochemical markers for ILC: gross cystic disease fluid protein 15, estrogen and progesterone receptors enabled a correct diagnosis. After a six year disease-free period, relapse occurred with severe obstruction due to rectal metastasis from lobular breast carcinoma. Since there was no widespread metastatic disease, surgery with concomitant hormonal therapy was performed.
