Intracerebroventricular injection of spexin stimulates the hypothalamic-pituitary-testicular axis and increases the secretion of male reproductive hormones in rats.

Background: Male reproductive functions are regulated in the hypothalamic-pituitary-gonadal (HPG) axis. Any problem in this axis would lead to the deterioration of reproductive functions. The present study aimed to investigate the effects of intracerebroventricular (icv) Spexin (SPX) infusion on the HPG axis in detail.

In the present study, the impact of intracerebroventricular (icv) PROK2 infusion on hypothalamic-pituitary-gonadal axis (HPG) hormones, testicular tissues, and sperm concentration was investigated.

Methods And Results: Rats were randomly divided into four groups: control, sham, PROK2 1.

Protective effect of astaxanthin on testis torsion/detorsion injury through modulation of autophagy.

A significant clinical condition known as testicular torsion leads to permanent ischemic damage to the testicular tissue and consequent loss of function in the testicles. In this study, it was aimed to evaluate the protective effects of Astaxanthin (ASTX) on testicular damage in rats with testicular torsion/detorsion in the light of biochemical and histopathological data. Spraque Dawley rats of 21 were randomly divided into three groups; sham, testicular torsion/detorsion (TTD) and astaxanthin + testicular torsion/detorsion (ASTX + TTD).

Enhancement of enzyme activity by laser-induced energy propulsion of upconverting nanoparticles under near-infrared light: A comprehensive methodology for in vitro and in vivo applications.

If the appropriate immobilization method and carrier support are not selected, partial decreases in the activity of enzymes may occur after immobilization. Herein, to overcome this challenge, an excitation mechanism that enables energy transfer was proposed. Modified upconverting nanoparticles (UCNPs) were constructed and the important role of near-infrared (NIR) excitation in enhancing the catalytic activity of the enzyme was demonstrated.

Effects of the apricot diets containing sulfur dioxide at different concentrations on rat testicles.

Due to its antioxidant and antimicrobial properties, sulfur dioxide (SO) is widely used in foods and beverages to prevent the growth of microorganisms and to preserve the color and flavor of fruits. However, the amount of SO used in fruit preservation should be limited due to its possible adverse effects on human health. The present study was designed to investigate the effects of different SO concentrations in apricot diets on rat testes.

Activation of the Mas receptors by AVE0991 and MrgD receptor using alamandine to limit the deleterious effects of Ang II-induced hypertension.

The MrgD receptor agonist, alamandine (ALA) and Mas receptor agonist, AVE0991 have recently been identified as protective components of the renin-angiotensin system. We evaluated the effects of ALA and AVE0991 on cardiovascular function and remodeling in angiotensin (Ang) II-induced hypertension in rats. Sprague Dawley rats were subject to 4-week subcutaneous infusions of Ang II (80 ng/kg/min) or saline after which they were treated with ALA (50 μg/kg), AVE0991 (576 μg/kg), or ALA+AVE0991 during the last 2 weeks.

Protective effect of dexpanthenol against methotrexate-induced liver oxidative toxicity in rats.

Methotrexate is a familiar chemotherapeutic preferred in a wide range of clinical fields such as leukemia, psoriasis, rheumatoid arthritis, neoplastic and autoimmune disorders. However, methotrexate therapy has limitations as it causes severe side effects from which liver damage is the most important one. Several antioxidant compounds have been studied against methotrexate related liver toxicity, but dexpanthenol has not been experienced.

Protective effects of dexpanthenol in carbon tetrachloride-induced myocardial toxicity in rats.

Exposure to various organic compounds including several environmental pollutants and drugs can cause cellular damage through the generation of lipid peroxidation products. Carbon tetrachloride (CCl) is a potent toxic agent that causes peroxidative degeneration in many tissues. Dexpanthenol (Dxp) is a member of the B complex vitamins that exhibits antioxidant effects against lipid peroxidation products.

Effects of taurine and apocynin on the zone of stasis.

Background: Among the zones of coagulation, hyperemia and stasis that occur in the burned area, the most intense metabolic process and the highest sensitivity to recovery with treatment is the zone of stasis.This metabolic process is related to how well the tissues in the zone of stasis can cope with oxidative stress. If the tissues in the zone of stasis are saved, the burn area will potentially heal faster and with less scar.

Effects of Low- and High-Dose Valproic Acid and Lamotrigine on the Heart in Female Rats.

Epilepsy is a chronic neurological disease that affects more than 50 million people worldwide. Antiepileptic drugs (AEDs) are the mainstay of treatment for most patients with epilepsy. However, AEDs have been reported to be associated with adverse cardiac effects.

Photocrosslinkable gelatin/collagen based bioinspired polyurethane-acrylate bone adhesives with biocompatibility and biodegradability.

Hard or soft tissue adhesives have been presented as a promising candidate to replace traditional wound closure methods. However, there are mechanical strength problems in biological adhesives and biocompatibility problems in synthetic-based adhesives. At this point, we aimed to remove all these disadvantages and produce a single adhesive that contains all the necessary features and acrylate functionalized UV-curable polyurethane formulations were produced with high crosslink density, high adhesion strength, biocompatibility and injectable property for easy application as potential biomedical adhesives.

Effects of antiepileptic drugs on ovaries of female Wistar rats.

Valproate (VPA) induced changes in ovarian morphology are observed in humans with epilepsy and in non-epileptic animals. The effects of lamotrigine (LTG) on female reproduction is not well known. We investigated whether LTG might be a safer drug for use with patients of reproductive age.
