Endoplasmic reticulum stress and associated apoptosis are linked with the pathogenesis of white striping in broiler breast muscles.

White striping (WS) that appears as white stripes parallel to the muscle fibrils is an emerging growth-related abnormality of broiler breast meat. The pathomechanism of this defect has not been fully understood despite intensive studies over the past decade. In the present study, endoplasmic reticulum (ER) stress and its associated apoptotic pathways were investigated to elucidate the potential role of these pathways in the development of WS.

Carbon monoxide (CO) derived from the CO-releasing molecule CORM-2 reduces peritoneal adhesion formation in a rat model.

Background: Although low-dose carbon monoxide (CO) administration has been shown to have an anti-fibrotic effect in various fibrotic diseases, its effects on peritoneal adhesion (PA), one of the postoperative complications, are not elucidated. In this study, the effect of CO-releasing tricarbonyldichlororuthenium (II) dimer (CORM-2) administration on the formation of PA and the underlying factors of its potential effect were investigated.

Methods And Results: After the induction of PA, rats were divided into four groups with 8 rats in each group.

Evaluation of Acetic Acid-Induced Chronic Gastric Ulcer Healing by Propionyl-L-Carnitine Administration.

The aim of our study was to investigate the healing effect of propionyl-L-carnitine (PLC) on chronic gastric ulcers and its underlying mechanisms. This study included rats with gastric ulcers induced by applying serosal glacial acetic acid. These rats were then given either saline (vehicle) or PLC at doses of 60 and 120 mg/kg, administered orally 3 days after ulcer induction for 14 consecutive days.

Dietary quercetin maintains the semen quality in rabbits under summer heat stress.

This study focused to determine beneficial impact of feeding quercetin supplemented diet on semen quality in summer heat imposed rabbits. Twelve heat stressed (HS) adult rabbits bucks were either fed with basal diet (HS; n = 06) or quercetin supplemented diet (QU-HS; n = 06) for a period of 56 days. Semen samples were collected and evaluated for volume, osmolality, morphology, concentration, motility, motion kinetics, viability, acrosome integrity, mitochondrial potential, and seminal plasma MDA level.

Quercetin supplemented diet improves follicular development, oocyte quality, and reduces ovarian apoptosis in rabbits during summer heat stress.

The present study was designed to test the modulatory effect of dietary quercetin on follicle population, apoptosis, in vitro maturation rate and quality of oocytes in heat stressed female rabbits. A total of thirty-four New Zealand White heat stress (HS) exposed female rabbits were either fed with quercetin supplemented diet (QU-HS) or non-supplemented (HS) diet. Firstly, laparotomy was performed for oocyte retrieval and then, oocyte grading and COCs dimensional assessments were conducted.

The effects of lycopene on DNA damage and oxidative stress on indomethacin-induced gastric ulcer in rats.

Background And Aims: Lycopene, the main antioxidant compound present in tomatoes, has high singlet oxygen- and peroxyl radicals-quenching ability, resulting in protection against oxidative damage in aerobic cell. Indomethacin is a nonsteroidal anti-inflammatory drug, and can promote oxidative damage in gastric tissue. The aim of this study was to investigate the protective effects of lycopene on an indomethacin-induced gastric ulcer model.
