Unravelling the impact of heat stress on daughter pregnancy rate in Mehsana buffalo through innovative breeding interventions.

Heat stress profoundly affects the reproductive success of buffaloes, which are vital for the dairy industry due to their unique anatomical and physiological characteristics, necessitating careful evaluation under such conditions. Hence, this guided our search for quantifying heat stress' impact on Mehsana buffaloes using the best THI model and evaluating sires' performance. Fertility records (days open converted to daughter pregnancy rate) were collected in the span of over 24 years, w.e.f. 1989 to 2012. Finally, 3070 records of first lactation cows, daughters of 117 sires from DURDA, Gujarat, India, were used in the analysis. Meteorological data were retrieved from IMD, Pune, to understand the relationship between daughter pregnancy rate (DPR) and heat stress indicators. Several heat stress models were compared based on R2, adjusted R2, AIC, and BIC values, and the impact of heat stress was quantified. The year was classified into different heat stress zones, viz., Non heat stress zone (NHSZ), Heat stress zone (HSZ), and critical heat stress zone (CHSZ), drawing from the findings of DPR and THI. The THI 4th model based on dry and wet bulb temperature was identified as the best-fit model, and DPR significantly changed (P < 0.01) by 1.14% per unit change in THI value based on the month of calving. The average EBVs of the sires for DPR were found to be 20.78% (NHSZ), 38.09% (HSZ), and 39.08% (CHSZ) using BLUP-SM and 20.78% (NHSZ), 37.30% (HSZ), and 38.87% (HSZ) using BLUP-AM. Subsequently, the optimum sire for each of the zones was prioritized. It is noteworthy that bulls that performed better in NHSZ did not perform as well in HSZ and CHSZ, and vice versa. This supports the possibility of evaluating bulls independently in each heat stress zone.

Complete genome sequence and genetic organization of a Garlic virus D infecting garlic (Allium sativum) from northern India.

The present paper describes first full genome sequence of the Garlic virus D (GarV-D) from northern India with a genome size of 8425 bp long ssRNA. The infected leaves and bulbs of garlic variety Yamuna Safed (G-282) plants suspected for GarV-D infection were collected with the aim to identify contagion virus during March, 2018. The total RNA was extracted from the pooled garlic plants using TRIzol reagent and sequenced using an Illumina HiSeq 2000 platform. BLASTn search in the NCBI database identified contagion as GarV-D (MK518067). It shared 83.63-85.83% nucleotide sequence identities with other (GarV-D) isolates from Argentina (KF550407, KF555653, KR819505) and 83.15% with isolates from China (MF795136, MF363012). Keywords: Allium sativum; Allexivirus; Garlic virus D; India.

Study on Corticosteroids use Pattern in Dermatological Practice and Investigating Adverse Effect of Corticosteroids Including its Associated Factors.

Background Corticosteroids are highly effective drugs with anti-inflammatory and immunosuppressive properties. Due to this, they have become a mainstay of pharmacotherapy in dermatology. However, improper and long term uses are associated with a number of serious adverse effects. Objective To investigate the corticosteroids use pattern, adverse effects and various factors associated with adverse effects in dermatological practice. Method A cross-sectional study was conducted in a dermatology department of tertiary care hospital. All patients using at least one corticosteroids, either topically or systemically or the combination were included in this study. Informed consent was taken from the patients and interviewed using structured questionnaire. Statistical analysis was performed by using SPSS 20. p-value < 0.05 was considered as statistically significant. Result Among the 60 participants under this study, 81.67% of them were females. The mean (±SD) age of the patients was 31.03 years (±15.0). A majority (58.30%) of the patients was prescribed with topical corticosteroids with low potency (25%). Most of them had used corticosteroids for urticaria. Adverse effects were reported by 33.30% of the patients. The most common adverse effect reported was the shedding of skin. Adverse effects was significantly associated with gender; use of systemic corticosteroids; regular use of corticosteroids; discontinuation of dose abruptly; and missed dose. However, there was no significant association between adverse effects and the duration of use of corticosteroids. Conclusion In conclusion, the present study suggested that the proper counselling and clear instruction regarding the use of corticosteroid should be provided to the patients for avoiding the abrupt discontinuation of the prescribed medication leading to treatment failure.

Leucas aspera: A review.

Leucas aspera commonly known as 'Thumbai' is distributed throughout India from the Himalayas down to Ceylon. The plant is used traditionally as an antipyretic and insecticide. Medicinally, it has been proven to possess various pharmacological activities like antifungal, antioxidant, antimicrobial, antinociceptive and cytotoxic activity. Further, studies reveal the presence of various phytochemical constituents mainly triterpenoids, oleanolic acid, ursolic acid and b-sitosterol, nicotine, sterols, glucoside, diterpenes, phenolic compounds (4-(24-hydroxy-1-oxo-5-n-propyltetracosanyl)-phenol). These studies reveal that L. aspera is a source of medicinally active compounds and have various pharmacological effects; hence, this drug encourage finding its new therapeutic uses.
