Additional intracervical prostaglandin reduces induction to calving time in buffaloes affected with incomplete cervical dilatation post-uterine detorsion.

Conventional induction protocol (CIP) of calving in buffaloes employs the intramuscular (IM) administration of dexamethasone (40 mg) and cloprostenol sodium (500 μg). If there is no progression in terms of cervical dilatation, then a second dose of cloprostenol sodium (500 μg) is administered intramuscularly. This protocol possesses certain demerits: (1) a wide range of response time intervals, and (2) increased risk of fetal membrane retention.

Thoracic and abdominal aortic alterations in dogs affected with systemic hypertension.

Aortic remodeling is the consequence of untreated systemic hypertension along with aortic dilatation as a marker for target organ damage in human literature. Therefore, the present study was planned to detect the changes in aorta at the level of aortic root via echocardiography, thoracic descending aorta via radiography and abdominal aorta via ultrasonography in healthy (n = 46), diseased normotensive (n = 20) and systemically hypertensive dogs (n = 60). The aortic root dimensions were measured at the level of aortic annulus, sinus of valsalva, sino-tubular junction and proximal ascending aorta via left ventricular outflow tract view of echocardiography.

Nano-depletion of morbid spermatozoa up-regulate Ca2+ channel, depolarization of membrane potential and fertility in buffalo.

Despite recent advances in technique of spermatozoa cryopreservation, there are still ejaculates present that fail to meet strict quality standard; mainly due to detrimental effect of imbalance of free radicals. The omnipresence of dead/defective spermatozoa in ejaculates of eutherian species is a major source of excessive free radicals. Though sperm-selection techniques, as well as addition of antioxidants addressed the problem to a certain extent, the major source of free radicals in the semen remained, causing much damage.

Intrauterine proteolytic enzymes therapy hastens expulsion of fetal membranes in dystocia affected buffaloes.

Background: Difficult calving (dystocia) in buffalo cows is a major obstetrical problem which further leads to metritis complex, encompassing the retention of fetal membranes (RFM), puerperal metritis, endometritis and pyometra with impaired future fertility.

Aims: The current study aimed to evaluate the effect of the administration of intrauterine proteolytic enzymes on the expulsion of fetal membranes and postpartum fertility in dystociac buffaloes.

Methods: Proteolytic enzymes consisting of Trypsin (16 mg), Chymotrypsin (16 mg), and Papain (8 mg) were dissolved in 500 ml normal saline were administered after 1 h of assisted delivery in dystociac buffaloes along with the conventional therapy.

A review on applications and toxicities of metallic nanoparticles in mammalian semen biology.

The advent of nanotechnology since the 1950s, when the well-known physicist Richard P. Feynman talked in his famous talk about "There's plenty of room at the bottom", has led to incredible contribution of nanotechnology in the fields of medical and veterinary therapeutics, diagnostics and other applications. Semen biology dealing with the study of spermatozoa and its related physiological and pathological aspects has not remained unscathed from the facets of nanotechnology.
