Sarcoptic mange in domestic rabbits: Pathogenesis, impact, and control strategies.

This review article provides an in-depth examination of sarcoptic mange in domestic rabbits (Oryctolagus cuniculus), a widespread and highly contagious dermatological condition caused by Sarcoptes scabiei var. cuniculi mites. Sarcoptic mange poses significant health risks to rabbits and can lead to severe economic losses in commercial rabbit farming due to decreased productivity, inferior leather quality, and increased mortality rates.

Lead and calcium crosstalk tempted acrosome damage and hyperpolarization of spermatozoa: signaling and ultra-structural evidences.

Background: Exposure of humans and animals to heavy metals is increasing day-by-day; thus, lead even today remains of significant public health concern. According to CDC, blood lead reference value (BLRV) ranges from 3.5 µg/dl to 5 μg/dl in adults.

Dietary Chromium Picolinate Supplementation Improves Glucose Utilization in Transition Calf by Ameliorating Insulin Response.

The decrease in insulin sensitivity during the transition of preruminant calves into ruminant animals is the common denominator. Meanwhile, this adaptation predisposes dairy calves towards various health issues and metabolic disorders that occur in later life. Chromium (Cr) has been shown to potentiate insulin functioning and is thereby helpful in reducing the risk of these metabolic disorders.

Collapsed mitochondrial cristae in goat spermatozoa due to mercury result in lethality and compromised motility along with altered kinematic patterns.

Earlier we have reported mercury-induced alterations in functional dynamics of buck spermatozoa through free radicals-mediated oxidative stress and spontaneous acrosome reaction. Based on our earlier findings, we aimed to investigate the effect of mercury exposure on motility, kinematic patterns, DNA damage, apoptosis and ultra-structural alterations in goat spermatozoa following in vitro exposure to different concentrations (0.031-1.

Mercury-Induced Inhibition of Tyrosine Phosphorylation of Sperm Proteins and Altered Functional Dynamics of Buck Spermatozoa: an In Vitro Study.

Present study was undertaken on buck spermatozoa to investigate the effect of mercuric chloride on functional dynamics of buck spermatozoa. Four different concentrations (0.031, 0.

Extra and intracellular calcium signaling pathway(s) differentially regulate histamine-induced myometrial contractions during early and mid-pregnancy stages in buffaloes (Bubalus bubalis).

This study examines the differential role of calcium signaling pathway(s) in histamine-induced uterotonic action during early and mid-pregnancy stages in buffaloes. Compared to mid pregnancy, tonic contraction, amplitude and mean-integral tension were significantly increased by histamine to produce myometrial contraction during early pregnancy with small effects on phasic contraction and frequency. Although uterotonic action of histamine during both stages of pregnancy is sensitive to nifedipine (a L-type Ca channels blocker) and NNC55-0396 (T-type Ca channels blocker), the role of extracellular calcium seems to be more significant during mid-pregnancy as in this stage histamine produced only 9.

Lead Modulates Calcium Entry and Beta-Adrenoceptors Signaling to Produce Myometrial Relaxation in Rats.

Modulation of myometrial spontaneity by lead acetate trihydrate (Pb) and its regulatory pathways were studied in estrogenized rats. Isometric tension in myometrial strips under a resting tension of 1 g was measured using data acquisition system-based physiograph and Lab Chart Pro v7.3.

Lead-induced adverse effects on the reproductive system of rats with particular reference to histopathological changes in uterus.

Objectives: This study was undertaken to elucidate the adverse effect of lead on female reproductive system following in vivo exposure in rats.

Materials And Methods: Animals of Group II, III and IV received lead acetate in drinking water (30, 100 and 300 ppm, respectively) for 28 days whereas Group I served as control. Lead levels in digested blood and bone samples were measured using atomic absorption spectrophotometer.

Calcium influx and release mechanism(s) in histamine-induced myometrial contraction in buffaloes.

The present study was undertaken to characterize the presence of histamine H1R using molecular biology tools and unravel the influx and release mechanism(s) involved in calcium signalling cascades in histamine-induced myometrial contraction in buffaloes. The presence of H1R mRNA transcript and immunoreactive membrane protein in buffalo myometrium was confirmed by RT-PCR and Western blot analysis. Further, histamine produced concentration-dependent (1nM-10μM) contraction in buffalo myometrium with a potency of 7.
