Gene Expression of Glycolysis Enzymes in MCF-7 Breast Cancer Cells Exposed to Warburg Effect and Hypoxia.

Hypoxia can cause significant changes in the glucose metabolism of cancer cells that prefer aerobic glycolysis for energy production instead of the conventional oxidative phosphorylation mechanism. In this study, breast cancer cells (MCF-7) were exposed to glucose (0-5.5-15-55 mM), during specific incubation periods (3, 6, 12, or 24 hours) under normoxic and hypoxic conditions.

Cytotoxic and Apoptotic Effect of Nanoclinoptilolite on Canine Osteosarcoma Cell Lines.

Introduction: Clinoptilolite has antiviral, antibacterial, anti-inflammatory, antidiabetic, and anticancer properties due to its biological activities. In various cancer cell culture studies, it has been reported effective against tumour cells and gave positive results in treatment of various tumours in dogs. No study was found on the effects of the nanoparticulate form, nanoclinoptilolite, on cancer cells.

The protective effects of vitamin C on the DNA damage, antioxidant defenses and aorta histopathology in chronic hyperhomocysteinemia induced rats.

The aim of this study was to investigate the protective effect of vitamin C towards hyperhomocysteinemia (hHcy) induced oxidative DNA damage using the comet assay. The increase in plasma homocysteine levels is an important risk factor for vascular and cardiovascular diseases through free radical production. This study was also conducted to investigate the histopathological changes in the thoracic aorta and the oxidant/antioxidant status in heart, liver and kidney tissues.

Acute phase protein levels in pregnancy and oestrus cycle in bitches.

The purpose of this study was to evaluate the acute phase protein (serum amyloid A, C-reactive protein, haptoglobin, ceruloplasmin and fibrinogen) profiles in pregnant dogs as well as bitches at various stages of the estrus cycle and to verify possible relationship(s) among the APPs profile and hormonal status. A total of 60 bitches of various breeds were enrolled. The animals were divided into six groups.

Effects of xylene and formaldehyde inhalations on renal oxidative stress and some serum biochemical parameters in rats.

In this study, it was aimed to demonstrate the possible renal oxidative stress and some serum biochemical parameters and their alterations caused by the exposure to xylene and formaldehyde (HCHO) in rats. Weighing 150-200g, 12-week-old, 24 female Sprague-Dawley rats were used. The rats were randomly divided into four groups: Group 1 (control), Group 2 (300-ppm technical xylene), Group 3 (6-ppm HCHO) and Group 4 (150-ppm technical xylene + 3-ppm HCHO).

Effects of xylene and formaldehyde inhalations on oxidative stress in adult and developing rats livers.

In this study, it was aimed to demonstrate the possible oxidative stress caused by exposure of xylene and formaldehyde (HCHO) on liver tissue, and on body and liver weights in adult as well as developing rats. The rats (96 female Sprague-Dawley) were randomly divided into four groups: embryonic day 1 (Group 1), 1-day-old infantile rats (Group 2), 4-week-old rats (Group 3) and adult rats (Group 4). The animals were exposed to gases of technical xylene (300 ppm), HCHO (6 ppm) or technical xylene + HCHO (150 ppm + 3 ppm), 8 hours per day for 6 weeks.

Dogs with Hepatozoon canis respond to the oxidative stress by increased production of glutathione and nitric oxide.

Canine hepatozoonosis is a disease caused by the tick-borne protozoan Hepatozoon spp. It has been reported in the United States, southern Europe, the Middle East, Africa and the Far East. In Turkey, canine hepatozoonosis was reported for the first time in 1933.
