The aim of this study was to identify the effects adding quercetin (Q) Tris extender in order levels oxidative stress bull sperm after freeze thawing. Ejaculates were collected via artificial vagina from Holstein bulls. Semen divided into five tools and diluted a final concentration 15 × 10

Contents The aim of this study was to compare pregnancy per artificial insemination (P/ AI ) after timed with sex‐sorted sperm ( SS or conventional semen CS in lactating dairy cows. Cyclic cows (n = 302) were synchronized by O vsynch and randomly assigned into two groups at the time . Cows a follicle size between 12 18 mm clear vaginal discharge inseminated either frozen‐thawed 148) 154) same bull. A shallow uterine performed horn ipsilateral side probable impending ovulation. Pregnancy on D...

The aim of this study was to determine the effects thymoquinone (TQ), which is most essential active compound Nigella sativa, on spermatological parameters ram semen during cryopreservation. Ejaculates were collected from five Sonmez rams using an artificial vagina and extended with Tris-based extender not containing TQ (control, 0 μg/ml TQ) 10, 25, 50 100 TQ. samples equilibrated in a + 4°C cold cabinet for 2 h. After h, loaded into 0.25 ml French straws. straws frozen by liquid nitrogen...

Contents The objectives of this study were to compare glycerol and ethylene glycol at different concentrations as cryoprotectants lycopene or cysteamine (with/without) antioxidants in T ris extender for bull semen. Twenty‐four ejaculates obtained from three bulls. Each ejaculate was split into four equal aliquots diluted using both the Tris extenders with (5% 7%) (3% 5%). After that, each added 5 m 500 μg/ml, control (without additives). addition 7% cysteamine, 5% 3% groups gave lowest CASA...

Nasal drug delivery is an interesting route of administration for metoclopramide hydrochloride (MTC) in preventing different kind emesis. Currently, the routes antiemetics are oral or intravenous, although patient compliance often impaired by difficulties associated with acute emesis invasiveness parenteral administration. In this perspective, nasal dosage forms (solution, gel, and lyophilized powder) MTC were prepared using a mucoadhesive polymer sodium carboxymethylcellulose (NaCMC). vitro...

BACKGROUND: To investigate the effectiveness of melatonin in preventing post-operative adhesion formation and to compare it with efficacy hyaluronate/carboxymethylcellulose membrane a rat model. MATERIALS METHODS: Following pilot studies, 35 rats were operated on full study. In 15 animals (group one), 10 standard lesions inflicted each uterine horn (total 30 horns) was applied before closure abdomen. second group, 20 one horns treated other served as control. Second-look operations performed...

This study aimed to investigate the effectiveness of using red pine bark tree extract (P; Pinus brutia Ten) as a TRIS extender in an attempt prevent oxidative stress bull spermatozoa after freezing. Semen specimens were obtained from Simmental bulls via artificial vagina and pooled. They separated into five diluted with Tris consisting P (200, 100, 50 25 µg/ml) free (control; C) up final concentration 16 × 106 per straw. All equilibrated for period 4 hr at temperature 4°C, following which...

We conducted this study to determine the potential cryopreservative effects of different hesperidin (vitamin P; H) doses on ram semen after freeze-thawing. Semen samples were obtained from Sönmez rams using an artificial vagina. The divided into six groups: control, 10, 50, 100, 250, and 500 µg/mL H (C, H10, H50, H100, H250, H500, respectively). At end study, sperm motility kinetic parameters, acrosome integrity (AI), mitochondrial membrane (MMP), viability, lipid peroxidation levels (LPL),...

Abstract To the best of our knowledge, no research has been conducted to test effects syringic acid (SA) on ram semen freezing within scope natural antioxidants added extenders. Therefore, this study had two main objectives. First, whether adding SA extender a protective effect and contributes positively sperm kinetic, plasma acrosome integrity, mitochondrial membrane potential, lipid peroxidation, oxidant antioxidant DNA damage parameters after thawing. Second, it was determine at what...
