Estimation of the seminal parameters of rooster and its association with fertility traits in synthetic dam line.

The objective of the present study was to assess the seminal parameters of rooster and its association with fertility traits (%), viz., hatchability of the fertile egg set (HFES), hatchability of the total egg set (HTES), and fertility (FERT). The data records pertained to traits of interest were obtained from various registers maintained at Poultry farm, of the Department of Animal Genetics and Breeding, Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar (India). The relationship between seminal and fertility characteristics was investigated using regression analysis and correlation. Moreover, the efficacy of seminal characteristics to distinguish between roosters with low and high fertility traits was evaluated using linear discriminant analysis (LDA). The findings showed that reproductive traits and seminal characteristics were significantly (P < 0.05) correlated. The LDA showed that the seminal parameters can effectively separate the roosters into those with high and poor reproductive features. It was revealed from LDA that seminal features showed higher classification accuracy for FERT (80.77%). Hatchability is dependent on eggs that have been artificially incubated; hence, these crucial traits are comparatively weaker for HTES (65.38%) and HFES (67.31%). Cross-validation of the seminal parameter LDA corroborated the aforementioned and related conclusions. It is suggested that the studied LDA function may be utilised to choose genotypes with improved reproductive traits based on seminal variables.

Silver decorated CeO2 nanoparticles for rapid photocatalytic degradation of textile rose bengal dye.

High quality silver (Ag) decorated CeO2 nanoparticles were prepared by a facile one-step chemical method. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), High resolution transmission electron microscopy (HR-TEM), fourier transform infrared spectrometer (FT-IR), electron paramagnetic resonance (EPR), X-ray photoelectron spectroscopy (XPS), UV-Visible absorption (UV-Vis), photoluminescence (PL) and thermogravimetric analysis. The decoration of Ag on CeO2 surface was confirmed by XRD, EPR and HR-TEM analysis. Harmful textile pollutant Rose Bengal dye was degraded under sunlight using the novel Ag decorated CeO2 catalyst. It was found that great enhancement of the degradation efficiency for Ag/CeO2 compared to pure CeO2, it can be ascribed mainly due to decrease in its band gap and charge carrier recombination rate. The Ag/CeO2 sample exhibited an efficient photocatalytic characteristic for degrading RB under visible light irradiation with a high degradation rate of 96% after 3 h. With the help of various characterizations, a possible degradation mechanism has been proposed which shows the effect of generation of oxygen vacancies owing to the decoration of Ag on the CeO2 surface.

Cu-mediated synthesis of differentially substituted diazepines as AChE inhibitors; validation through molecular docking and Lipinski's filter to develop novel anti-neurodegenerative drugs.

A highly efficient Cu-mediated route for the synthesis of fused [1,2,3]triazolo[1,4]diazepines has been developed by azidation-cyclization of 2-bromo-N-propargylamines in a one-pot fashion. The key highlight of the present work is that the 2-bromo-N-propargylamines are prepared through the A3-reaction of cyclic amines such as isoquinoline and decarboxylative coupling of proline and pipecolinic acid with 2-bromo benzaldehyde and alkyne. As preliminary, these compounds were analyzed for their most probable bioactivity using various in silico tools. The recognized anti-neurodegenerative activity potential was assessed by molecular docking, AChE inhibition activity in erythrocytes and DPPH radical scavenging activity potentials possessed by the compounds. With a relative AChE inhibition activity of 97% (IC50 0.25 ±â€¯0.02 µM), compound 5d identified as the most active compound. Druggability of these compounds also evaluated through Lipinski's filter and other ADMET tools for the betterment of selective execution of in vitro and in vivo activities of the screened compounds cautiously.

An eco-friendly catalytic system for multicomponent, one-pot synthesis of novel spiro-chromeno indoline-triones and their anti-prostate cancer potentials evaluated via alkaline phosphatase inhibition mechanism.

A green and efficient straightforward tactic for the one-pot regioselective synthesis of novel 10,10-dimethyl-9,10,11,11a-tetrahydro-6H-spiro[chromeno[4,3-b]chromene-7,3'-indoline]-2',6,8 (7aH) -triones (4a-n) in one-pot modus has been established using eco-friendly p-toluenesulphonic acid as catalyst. Among the solvents that were used for synthesis, 4a-n were suitably synthesized with maximum yield (90-98%) in water. We avoided column purification and the formed by-product in the process is environmental-friendly. Hence, this reaction may consider as an astonishing piece work in this study, why because, the reaction mechanism that depends on the nature of the group attached to the isatin ring nitrogen atom. The main advantage of this protocol includes short reaction time, good yield, easy to work-up, practical simplicity, high regioselectivity and reduced pollutant, cost and avoids tedious purification. These pharmaceutically important compounds (4a-n) were recognized for their alkaline phosphatase inhibition and prostate cancer medication capabilities. The selective activity relation between alkaline phosphatase and prostate cancer was unveiled through the interaction of 4a-n to Human alkaline phosphatase (PDB ID: 1EW2).

A retrospective analysis of acute organophosphorus poisoning cases admitted to the tertiary care teaching hospital in South India.

OBJECTIVES: We have herein reported our experience with the pattern of presentation of cases of acute organophosphorus (OP) poisoning cases in a tertiary care hospital. MATERIALS AND METHODS: This retrospective study evaluated the hospital records of patients with acute OP poisoning. In a pre-structured proforma, data regarding age, sex, time elapsed after intake, circumstances of poisoning, duration of hospitalization, severity, complications, and outcome of the patients were recorded. The data were presented as mean ± standard deviation, entered in the open office datasheet, and analyzed with PSPP software. RESULTS: A total 101 patients were included in the study. Young adult males were more commonly involved than females (M:F 2.5:1). The mean age of the patients was 28 years (range 2-72 years, SD ± 14.3 years). Mean time to receive treatment was 5.2 ± 7.4 (range 1-48 h). About 45.5% patients received first aid before coming to the hospital. The reason was suicide in 88.1% cases and accident in 12 (11.9%, all children). Seventy-nine patients received pralidoxime (PAM) and the mean duration was 1.7 ± 1.1 (range 1-4 days). Atropine was given in all patients. Mean duration was 5.1 ± 3.1 (range 1-19 days). Mean hospital stay was 7.5 ± 4.7 days (range 1-26 days). Mortality was 9.9% in the present series. CONCLUSION: Although the present study contribute substantial information regarding the epidemiology and outcome of acute OP poisoning in a tertiary care teaching hospital at a district level, its relatively small sample size and the retrospective record-based nature are the major limitations of the present study. There is a further need for prospective studies to understand the underlying socio-economic factors responsible for acute OP poisoning in our population, and, accordingly, address the problems to reduce the incidence of acute OP poisoning cases.

A retrospective review of snake bite victims admitted in a tertiary level teaching institute.

OBJECTIVE: Snake bite remains major public health problem worldwide. We present our experience with cases of snake bites managed in our tertiary care teaching center of South India. MATERIALS AND METHODS: The details of all patients with snake bite admitted to a tertiary teaching care hospital from 2010 to 2012 were retrospectively retrieved and reviewed. The details regarding age, gender, first aid received or not, time elapsed between the bite, emergency care management and ASV (Anti Snake Venom) administration, site of snake bite, clinical features at the time of presentation, local examination findings at the site of bite, duration of hospital stay, need for elective ventilation, details of investigations and outcome were reviewed. The data were analyzed in PSPP software (Free Software Foundation, Inc.) for window for statistical analysis, while standard deviation (SD) was applied for the continuous variables, and proportions were applied for the categorical variables. RESULTS: Mean age was 38.4 ± 14.8 years (range 4-70 years). Majority [72 (82.8%)] were farmers. In 86.2% patients, the site of bite was in lower limbs. Snake could be identified in only 20 cases [Cobra-12 (60%), Krait-2 (10%), and Viper-6 (30%)]. Mean time to reach to hospital was 12.1 ± 21.4 hours (range 1-120 hours). Mean anti-venom therapy duration was 3.2 ± 2.0 days (range 1-14 days). Mean hospital stay was 4.7 ± 3.1 days (range 1-15 days). Majority (72.4%) made good recovery; mortality was in 4.6% cases, and 20 (23%) patients left against medical advice. CONCLUSIONS: This study identified major epidemiological and management variables related to snake bite. There is a need for a well-planned data collection and information dissemination system to avoid this potentially preventable disease.

Optical and structural characterization of CdS/ZnS and CdS:Cu(2+) /ZnS core-shell nanoparticles.

Core-shell CdS/ZnS (Zn 0.025-0.125 M) and CdS:Cu(2+) (1%)/ZnS nanoparticles were successfully synthesized using a chemical method. X-ray diffraction (XRD), high-resolution transmission electron microscopy (HR TEM), photoluminescence (PL) and UV/Visible (UV/Vis) techniques were used to characterize the novel CdS/ZnS and CdS:Cu(2+) /ZnS core-shell nanoparticles. All absorption peaks of the synthesized samples were highly blue-shifted from the bulk CdS and ZnS. Very narrow and symmetric PL emission was observed in the yellow region for core-shell CdS/ZnS. Furthermore, the PL emission of CdS/ZnS was tuned into orange region by incorporate the Cu ion into the core CdS lattice.
