Chronic effects of maternal tobacco-smoke exposure and/or α-lipoic acid treatment on reproductive parameters in female rat offspring.

Prenatal tobacco-smoke exposure negatively affects the reproductive functions of female offspring and oxidative stress plays a major role at this point. Alpha-lipoic acid (ALA), well known as a biological antioxidant, has been used as a nutritional supplement and as a therapeutic agent in the treatment of certain complications during pregnancy. We aimed to investigate the effects of maternal tobacco-smoke exposure and/or ALA administration on puberty onset, sexual behavior, gonadotrophin levels, apoptosis-related genes, apoptotic cell numbers and oxidative stress markers in the adult female rat offspring.

Evaluation and characterization of extract-loaded chitosan nanoparticles as antimicrobial agents against some human pathogens.

With the increase of antibiotic resistance, which is present at a worrying rate, research on the use of newly developed nanoparticles as an antimicrobial agent with green biotechnology has intensified. The study aimed to investigate the antimicrobial effects of chitosan nanoparticles (CSNP) synthesized using extract (PE). Characterization of -loaded chitosan nanoparticles (PE-CSNPs) was performed with Fourier transform infrared spectrophotometer, X-ray diffraction, Field-emission scanning electron microscopy, Brunauer-Emmett-Teller, Differential scanning calorimetry, and zeta potential techniques.

The effects of morus nigra on the alveolar bone loss in experimentally-induced periodontitis.

Purpose: The aim of this study is to evalute the anti-inflammatory effects of morus migra on experimentally-induced periodontitis in rats.

Materials And Methods: Twenty-four Wistar-albino rats were randomly divided into three groups: control group (C, n=8), experimental periodontitis (PER, n=8), experimental periodontitis and treated with Morus nigra (MN+PER, n=8) (50 mg/kg per day for 21 days). After 21 days, the rats were sacrificed, and alveolar bones were evaluated histopathologically and histometrically analyzed to obtain level of alveolar bone loss.

TRPM2 mediates distruption of autophagy machinery and correlates with the grade level in prostate cancer.

Purpose: Transient receptor potential melastatin 2 (TRPM2), a calcium-permeable ion channel, is shown as a prognostic marker candidate in prostate cancer (PCa) and an important regulator of autophagy. We aimed to determine the changes in TRPM2 and autophagic-apoptotic gene expression levels in human prostate adenocarcinomas, and to investigate the affect of TRPM2 on autophagic pathways in PC-3 cell line.

Methods: Human prostate tissues were classified considering the grade levels and were divided into the control, BPH, and grade 1-5 groups.

The decrease in hippocampal transient receptor potential M2 (TRPM2) channel and muscarinic acetylcholine receptor 1 (CHRM1) is associated with memory loss in a surgical menopause rat model.

Introduction: The aim of the study was to investigate the association of transient receptor potential M2 (TRPM2) channel and muscarinic acetylcholine receptor 1 (CHRM1) activity with the memorial functions that are deteriorated in surgical menopause.

Material And Methods: A total of 14 female rats were randomly divided into 2 groups: group (G)1: sham group; group (G)2: surgical menopause group, the group in which bilateral ovariectomy was performed. Fourteen days after the surgical procedure, learning and memorial tests were performed in G1 and G2 for a totally 13 days.

Effects of long-term paroxetine or bupropion treatment on puberty onset, reproductive and feeding parameters in adolescent male rats.

Antidepressant use in adolescents has become more common in recent years. We have found several studies stating that prenatal antidepressant exposure can lead to delayed or earlier puberty onset but there was no study on postnatal paroxetine or bupropion. The main aim of this study was to investigate the effect of postnatal exposure to bupropion or paroxetine on puberty onset, reproductive and feeding results.

The investigation of effect of alpha lipoic acid against damage on neonatal rat lung to maternal tobacco smoke exposure.

This study was carried out to determine the changes in the lungs of the rat pups exposed to tobacco smoke during pregnancy period and to investigate the protective effects of alpha lipoic acid, which is administered during pregnancy, on these changes. Spraque-Dawley female rats were divided into four groups: control, tobacco smoke (TS), tobacco smoke + alpha lipoic acid (TS + ALA) and alpha lipoic acid (ALA). The rats in control group were untreated.

Effects of vitamin D on kidney histology and trpv1 channels in doxorubicin-induced nephropathy.

Doxorubicin (DXR) is an antineoplastic agent of the anthracycline group, and may show nephrotoxic effects in animal models and humans. We investigated changes in kidney tissue following doxorubicin treatment and the effects of vitamin D on kidney tissue and TRPV1 channels. In this study, 24 adult male Wistar Albino rats were used.

Irisin: a potentially candidate marker for myocardial infarction.

Myocardial infarction (MI) causes energy depletion through imbalance between coronary blood supply and myocardial demand. Irisin produced by the heart reduces ATP production by increasing heat generation. Energy depletion affects irisin concentration in circulation and cardiac tissues, suggesting an association with MI.
