In vivo exposure to a new 2-cyano-2-p-nitrophenyl-N-benzylthioamide decreases doxorubicin-triggered structural damages in the mature testis.

The use of doxorubicin (DOX) in clinical practice continues to be challenged by its severe toxicity. DOX cytotoxic activity is not only directed against malignant tumours, given that the treatment will damage healthy tissues as well leading to irreversible injuries. This study aimed to address the in vivo effects of DOX and its co-administration with a new analog of thioamide; thiocyanoacetamide (TA) on the germinal epithelium.

Neuroprotective effect of grape seed extract on brain ischemia: a proteomic approach.

Stroke is one of the leading causes of long-lasting disability in human and oxidative stress an important underlying cause. Molecular insights into pathophysiology of ischemic stroke are still obscure, and the present study investigated the protective effect of high dosage Grape Seed Extract (GSE 2.5 g/kg) on brain ischemia-reperfusion (I/R) injury using a proteomic approach.

Antioxidant and Anti-Apoptotic Activity of Octadecaneuropeptide Against 6-OHDA Toxicity in Cultured Rat Astrocytes.

Oxidative stress, associated with various neurodegenerative diseases, promotes ROS generation, impairs cellular antioxidant defenses, and finally, triggers both neurons and astroglial cell death by apoptosis. Astrocytes specifically synthesize and release endozepines, a family of regulatory peptides, including the octadecaneuropeptide (ODN). We have previously reported that ODN acts as a potent neuroprotective agent that prevents 6-OHDA-induced apoptotic neuronal death.

Endogenous Expression of ODN-Related Peptides in Astrocytes Contributes to Cell Protection Against Oxidative Stress: Astrocyte-Neuron Crosstalk Relevance for Neuronal Survival.

Astroglial cells are important actors in the defense of brain against oxidative stress injuries. Glial cells synthesize and release the octadecaneuropeptide ODN, a diazepam-binding inhibitor (DBI)-related peptide, which acts through its metabotropic receptor to protect neurons and astrocytes from oxidative stress-induced apoptosis. The purpose of the present study is to examine the contribution of the endogenous ODN in the protection of astrocytes and neurons from moderate oxidative stress.

Effect of White Kidney Beans (Phaseolus vulgaris L. var. Beldia) on Small Intestine Morphology and Function in Wistar Rats.

The chronic ingestion of raw or undercooked kidney beans (Phaseolus vulgaris L.) causes functional and morphological derangement in various tissues. The major objectives of this study were to investigate the gavage effects of a raw Beldia bean variety that is widely consumed in Tunisia, on the small intestine morphology and jejunal absorption of water, electrolytes, and glucose in Wistar rats.

Cadmium-induced autophagy in rat kidney: an early biomarker of subtoxic exposure.

Environmental exposures to cadmium (Cd) are a major cause of human toxicity. The kidney is the most sensitive organ; however, the natures of injuries and of adaptive responses have not been adequately investigated, particularly in response to environmental relevant Cd concentrations. In this study, rats received a daily ip injection of low CdCl₂ dose (0.

Michelin tire syndrome: a report of two siblings.

Michelin tire syndrome is a rare syndrome characterized by excessive folding of the skin. The diagnosis is mainly clinical. It has been found to be associated with noncutaneous anomalies, and probably reflects multiple underlying disorders.

[Vitamin A effects on morphometric adaptation after extensive small bowel resection in the rat].

This work was conceived to study, in the rat short bowel syndrome, the effect of precocious administration of retinoic acid on morphometric adaptation in the remnant intestine. Mitotic index, villous height, crypt depth and mucosal aspect were determined in 2 groups of rats (n=12) after 60% small bowel resection. 100 microg of retinoic acid were perfused immediately after resection in the first group.
