Evaluation of thiol/disulphide and oxidant-antioxidant status of dairy cows in periparturient and post-partum period.

Background: Thiol/disulphide homeostasis (TDH) has a critical role in many cellular activities such as antioxidant protection. Alterations of oxidative stress in the transition period play an important role in development of some diseases and disorders in dairy cows.

Objectives: The purpose of this study is to assess the total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), total thiol, native thiol, disulphide and lipid profile in Simmental and Montofon dairy cows (aged 2-3) before and after calving.

Investigation of Antiproliferative Effects of Combinations of White and Black Garlic Extracts with 5-Fluorouracil (5-FU) on Caco-2 Colorectal Adenocarcinoma Cells.

Garlic is rich in bioactive compounds that are effective against colon cancer cells. This study tests the antioxidant and antiproliferative effects of cold-extracted white and black garlic extracts. Black garlic extracted in water (SSU) exhibits the highest antioxidant activity, phenolic content, and flavonoid content, while black garlic extracted in ethanol (SET) shows the lowest values.

Vitamin A, calcium, phosphorus and magnesium status of heifers grazing in Northern Cyprus.

Vitamin A, calcium (Ca), phosphorus (P) and magnesium (Mg) are essential components for the health and reproductive yield of dairy cows. In this study, it is aimed to profile the calcium, phosphorus and magnesium elements together with vitamin A, which are important components in cattle bred and reared in Northern Cyprus. To analyse these parameters, 260 clinically healthy animals, at least 30 from each region, were blood sampled from eight different regions (Nicosia, Gecitkale, Vadili, Famagusta, Iskele, Ziyamet, Morphou and Kyrenia) during both summer and winter seasons.

Antioxidant therapy impresses in oxidative stress-induced kidney cells.

Introduction:   Renal cell cancer (RCC) is not a single entity, but consists of different types of tumors derived from various parts of the nephron (epithelium or renal tubules). It is known that cancer initiation and progression is related to the balance between oxidants and antioxidants directly. Interestingly, advanced stages of cancer such as metastasis, angiogenesis are associated with cell oxidative capacity.

GSM-like radiofrequency exposure induces apoptosis via caspase-dependent pathway in infant rabbits.

Background: There have been several Radio Frequency (RF) field researches on various populations and groups of different ages in recent years. However, the most important group for research has been declared as the pregnant women and their babies.

Objective: The aim of the study was to analyse the effect on apoptotic factors of RF fields on newborn rabbit liver tissues.
