The Effects of Ionotropic GABA Receptor Blockage on the Brain in Rats with Induced Sepsis.

Encephalopathy following sepsis is defined as life-threatening organ failure due to the irregular response of the host to infection and has high mortality and morbidity rates. The present study aimed to investigate the effects of inflammation and the gamma-aminobutyric acid-A (GABA) receptor antagonist, bicuculline, on brain tissue in rats with sepsis. Sepsis was experimentally generated using lipopolysaccharide (LPS).

Utility of melatonin on brain injury, synaptic transmission, and energy metabolism in rats with sepsis.

Melatonin is a powerful endogenous antioxidant hormone. Its healing effects on energy balance and neuronal damage associated with oxidative metabolism disorders have been reported in pathologic conditions. We aimed to determinate the utility of melatonin on neuronal damage, synaptic transmission, and energy balance in the brain tissue of rats with sepsis induced with LPS.

Is there a relationship between infertility and fertilin β protein distribution?

Introduction: Fertilin β is a sperm surface protein that can mediate sperm-egg membrane interaction. This study was conducted to determine whether the expression of fertilin β after intrauterine insemination (IUI) in donors with normal parameters after standard semen analysis is related to low success rate or failure of fertilization.

Methods: We examined the sperm of 30 male donors who have normal as controls, oligozoospermia, and unexplained infertility as the clinically indication for IUI.

A comparative study of the effects of gutta-percha solvents on human osteoblasts and murine fibroblasts.

We aimed to investigate the in vitro physiologic effects of xylene, chloroform, orange oil and eucalyptus oil solvents for dissolving gutta-percha on L929 and HOB cell lines; 2.5 and 10 μL mL of these solvents were tested for 24, 48 and 72 h. Gutta-percha solvents inhibited the proliferation rate of fibroblasts in a dose- and time-dependent manner; however, no inhibition was detected in HOB (evaluated using MTT assay).

Immunolocalization of Fertilin β, IZUMO1, and P34H in Ram Spermatozoa.

According to various reports, current methods of sperm freezing destroy the integrity of the sperm plasma membrane and acrosome. This study aimed to determine the changes in the existence and location of three proteins, namely fertilin β, IZUMO1, and P34H, in ram spermatozoa. By using frozen-thawed spermatozoa, ejaculated fresh spermatozoa, and testicular and epididymal spermatozoa (obtained from caput, corpus, and caudal regions), the localizations of the mentioned proteins were performed using signal labeling with indirect immunofluorescence, and the quantification of these proteins was compared using Western blot analyses.

Investigation of Physiological Effects Induced by Dehydroepiandrosterone in Human Endothelial Cells and Ovarian Cancer Cell Line.

Objectives: Dehydroepiandrosterone (DHEA) is an endogenous hormone that acts as a ligand for several cellular receptors. An age-dependent decline in circulating levels of DHEA is linked to changes in various physiological functions. In gynecological clinical practice, DHEA is commonly prescribed to induce ovulation.

Physiological Effects of Betahistine on Cell Lines of Various Origins.

Objectives: Betahistine is a histamine analog commonly prescribed for symptomatic treatment of vertiginous symptoms. studies have shown that betahistine was not toxic at the prescribed doses in a nasal epithelial cell line. However, the effect of betahistine on other cell types has not been studied.

Serum vitamin D levels in healthy urban population at reproductive age: effects of age, gender and season.

Objective: The aim of the study was to determine the effects of age, gender and season on vitamin D status in healthy urban population at reproductive age. Also, we investigated the distribution of population into different groups regarding 25(OH)D levels.

Methods: Serum 25(OH)D levels of 21,317 participants: 5,364 men (25.

Cell-Free Lactobacillus sp Supernatants Modulate Staphylococcus aureus Growth, Adhesion and Invasion to Human Osteoblast (HOB) Cells.

The increase of antibiotic resistance has become a problem. Probiotic bacteria play an important role in preventive/supportive medicine. Therefore, we examined the inhibitory effects of four different Lactobacillus species' (L.

A simple and inexpensive method for evaluation of in vitro cell adhesion on screws.

Only a limited number of techniques are available for assessing the effect of different coating materials on cell adherence to screws. In this study, we describe a simple and inexpensive method for evaluation of cell adhesion on irregular surfaces such as the surgical or implant screws. For this purpose, we prepared semi-submerged screws in the petri dishes using agar.

Antimuscarinic-induced convulsions in fasted mice after food intake: No evidence of spontaneous seizures, behavioral changes or neuronal damage.

Prolonged or repeated seizures have been shown to cause spontaneous recurrent seizures, increased anxiety‑related behavior, locomotor hyperactivity, impaired functions of learning and memory, and neuronal damage in the hippocampus and other brain regions in animals. Mice and rats treated with antimuscarinic drugs after fasting for two days or less develop convulsions after being allowed to eat ad libitum. To address whether such behavioral and neuroanatomic changes occur following these convulsions, mice treated i.
