Characteristics of Bachaur bull semen.

The Bachaur is a mediumized draft purpose breed which has been recognized by ICAR-National Bureau of Animal Genetic Resources (NBAGR) Karnal, India, and presently is on the verge of extinction. Since there are no data regarding the seminal parameters of this breed, this work was performed to evaluate seminal parameters of freshly ejaculated semen. A total of three healthy breeding Bachaur bulls aged 2.5-5 years were selected for the study which were maintained under identical managemental conditions. Semen parameters of these bulls were studied across 10 ejaculates. The average scrotal circumference and testicular weight of the three bulls were 27.78 ± 1.2 cm and 400.67 ± 26.6 g, respectively. The average overall volume (mL), pH, concentration (million/mL), liveability (%), abnormality (%), HOST (%) and acrosome integrity (%) were 2.20 ± 0.19, 6.86 ± 0.06, 1245.60 ± 23.49, 85.09 ± 0.91, 4.13 ± 0.06, 81.16 ± 1.18 and 83.54 ± 1.32, respectively. The average overall mass motility of three Bachaur bulls was 3.57 ± 0.06 in 0-5 scale and individual motility averaged 84.78 ± 1.70 per cent. The volume of ejaculates in Bachaur bull seemed to be lower as compared to other exotic and Indian breeds. However, the semen parameters with regard to mass motility, liveability, abnormalities, hypo-osmotic swelling test (HOST) and acrosomal integrity seemed similar to other exotic and Indian breeds.

Carbohydrate hitched imidazoles as agents for the disruption of fungal cell membrane.

The fungal diseases represent an increasing global health burden and have transformed from a rare curiosity to the leading cause of human mortality. The present manuscript reports the antifungal potential of two novel compounds possessing a carbohydrate and an imidazole moiety. Antifungal susceptibility test determined the growth inhibition potential of the synthesized compounds against Aspergillus niger 9689 and it was observed that compounds D and E gave an antifungal inhibitory index of 66.66 and 56.67% respectively. Further, ultra-structure analysis of the treated fungal mycelia through scanning electron microscope (SEM) and confocal microscopy indicated significant membrane permeability and disintegration of fungal cell membrane, thus highlighting the probable role of the synthesized compounds as inhibitors of fungal lanosterol 14α-demethylase. In silico studies corroborated with the in-vitro results, as the synthesized compounds interacted with the critical amino acids present at the active site of the fungal enzyme (lanosterol 14α-demethylase).
