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.

Altered luteal expression patterns of genomic and non-genomic progesterone receptors in bitches at different reproductive states.

The binding of steroid hormones to their specific receptors is necessary to exert their effects on target cells. Progesterone (P), a steroid hormone, carries out its effects through both genomic and non-genomic (the cell membrane-associated) receptors. This study aimed to ascertain luteal expression patterns of genomic and non-genomic progesterone receptors in bitches in physiological (early dioestrus and early pregnant) and pathological (pyometra) reproductive states.

An investigation of the distributions of ferroptosis and necroptosis mediators in the maternal-fetal interface at different days of rat pregnancy.

Ferroptosis and necroptosis are recognized as playing major roles in the regulation of various physiological processes. However, the physiological role of the cell death mediated by these two pathways in the developmental process has not yet been clearly established. This study investigated ferroptosis and necroptosis signalling pathways in maternal-fetal tissue in the different gestational days (GD) of rat pregnancy using immunohistochemical and western blot methods in order to fill this gap.

Oleuropein Mitigates Acrylamide-Induced Nephrotoxicity by Affecting Placental Growth Factor Immunoactivity in the Rat Kidney.

Objective: Oleuropein is one of the main components of the antioxidant properties of olive leaves. Placental growth factor is an important regulator in angiogenesis and inflammation, its levels being variable in pathological conditions. In this study, we aimed to examine changes in placental growth factor expression and the effect of oleuropein, found in olive leaves, in rats exposed to acrylamide nephrotoxicity.

An investigation of the endoplasmic reticulum stress in obesity exposure in the prenatal period.

Objectives: Exposure to maternal obesity has been shown to make offspring more prone to cognitive and metabolic disorders later in life. Although the underlying mechanisms are unclear, the role of endoplasmic reticulum (ER) stress in the fetal programming process is remarkable. ER stress can be activated by many chronic diseases, including obesity and diabetes.

Expression of placental growth factor and a disintegrin and metalloprotease with a thrombospondin type motifs 1-4-8 during the three trimesters of rat pregnancy at the maternal-fetal interface.

The functional roles of the a disintegrin and metalloprotease with a thrombospondin type motifs (ADAMTS) gene family in reproductive physiology, reproductive organs developments and adult reproductive health are still under investigation. The expression of the anti-angiogenic proteases ADAMTS-1, ADAMTS-4 and ADAMTS-8 in placental angiogenesis at various stages of pregnancy also remains unclear. The purpose of this study was therefore to determine the localization and expression of the ADAMTS-1, ADAMTS-4 and ADAMTS-8 proteins during the three stages of pregnancy in rats.

Expression of ADAMTS 1-4-8 and placental growth factor in ovary and oviduct during pregnancy in the first trimester.

A Disintegrin and Metalloprotease Domains with Thrombospondins Motifs (ADAMTS), proteinases responsible for the destruction of extracellular matrix structures, have essential roles in the physiological and pathological processes of the female reproductive system, which is a dynamic structure. This study aimed to evaluate the immunoreactivity of placental growth factor (PLGF) and ADAMTS' (1, -4, and -8) in the ovary and oviduct during pregnancy in the first trimester. Our findings suggest a predominant role of ADAMTS-4 and ADAMTS-8 as proteoglycan-degrading enzymes from the ADAMTS-1 in the first trimester.

Protective and therapeutic role of melatonin against tunicamycin-induced ER stress in testicular tissue of rats.

Objectives: This study aimed to investigate the possible consequences of administering exogenous melatonin as prevention or treatment against tunicamycin-induced endoplasmic reticulum (ER) stress in the testicular tissue of rats.

Materials And Methods: In this study, 42 adult Sprague Dawley rats, randomly divided into seven equal groups, were administered intraperitoneal tunicamycin to induce ER stress. Both prophylactic (PMel) and therapeutic melatonin (TMel) groups were administered melatonin for seven days.

The mixture of liquid foam soap, ethanol and citric acid as a new fixative-preservative solution in veterinary anatomy.

The present study investigates the efficiency of liquid foam soap, ethanol, citric acid and benzalkonium chloride as a fixative-preservative solution (a soap-and ethanol-based fixing solution, or SEFS). In this study, ethanol serves as the fixative and preservative, liquid foam soap as the modifying agent, citric acid as the antioxidant and benzalkonium chloride as the disinfectant. The goat cadavers perfused with SEFS (n=8) were evaluated over a period of one year with respect to hardness, colour and odour using objective methods.
