    Abstract The performance and productivity in poultry flocks are affected by climate change, especially in tropical islands. This study has been designed to understand the impact of two major seasons viz. summer (February-June) and rainy (July-September) on biochemical and immunological traits in three backyard poultry breeds viz. Desi (non-descript indigenous), Nicobari Fowl, and Vanaraja of Andaman and Nicobar Islands, India, for the first time. Ninety adult poultry birds were randomly selected from three different rural villages of the Andaman and Nicobar Islands including Desi (D, n = 30), Nicobari Fowl (NF, n = 30) and Vanaraja (V, n = 30). Ten birds each of D, NF and V from each village (sex ratio− 1:1) were chosen for the study. Serum samples collected (n=/bird/season/breed) from the three breeds were analysed. The study revealed that season had significant effect on biochemical parameters, i.e. serum albumin (p < 0.0001), globulin (p < 0.01), ALP (p < 0.05), total bilirubin (p < 0.05) and serum glutamic oxaloacetic transaminase (p < 0.05). Moreover, season had significant effect on immune parameters i.e. IL−2 (p < 0.0001), IL−4 (p < 0.0001), IL−6 (p < 0.0001&p < 0.05), HSP−70 (p < 0.0001&p < 0.01), TLR−4 (p < 0.01&p < 0.05) and INF-γ (p < 0.0001). It was observed that breed had significant effect on total bilirubin (D-V & NF-V, p < 0.0001), serum glutamic oxaloacetic transaminase (NF-V, p < 0.01 &D-V, p < 0.05). And also had significant effect on. IL−2 (D-NF, p < 0.001 &NF-V, p < 0.01), IL−4 (D-NF& D-V, p < 0.0001;NF-V, p < 0.05; D-V&NF-V, p < 0.01), IL−6 (D-NF & D-V, p < 0.0001), HSP−70 (D-NF & D-V, p < 0.0001; D-NF p < 0.01; NF-V, p < 0.05), and INF-γ (D-NF & D-V, p < 0.0001&D-NF, p < 0.05). This study could establish the seasonal influence on biochemical and immunological traits of rural backyard poultry breeds in tropical climate of Andaman and Nicobar Islands.

    Abstract This paper examined the pluripotent effect of supplementation of turmeric rhizome powder (TRP) (Curcuma longa) in growing Andaman local pigs. A total of 48 pigs were randomly allotted into four groups and fed diets containing TRP at 4 concentrations, that is, 0 (control group), 0.05 (treatment 1), 0.1 (treatment 2), and 0.2% (treatment 3) for 30 days. The mean body weight of pigs supplemented with 0.1% and 0.2% TRP was significantly higher than that of the control group (41.66 ± 0.44, 42.59 ± 0.33 vs 40.38 ± 0.30 kg; p ≤ 0.05) which indicated the effect of TRP as growth enhancer. A significant (p ≤ 0.05) decrease in serum concentration of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) was recorded in supplemented groups as compared to the control group. Creatinine kinase (U/l) decreased in all the treatment groups as compared to the control group. Total cholesterol, triglyceride, and low-density lipoprotein cholesterol decreased significantly after supplementation with 0.1% and 0.2% TRP in comparison to the control group. However, there was marked increase in high-density lipoprotein cholesterol (mg/dl) in all TRP-supplemented groups than the control group (27.67 ± 0.60 in T1, 32.76 ± 0.32 in T2, and 34.58 ± 0.37 in T3 vs. 23.73 ± 0.69 in control; p ≤ 0.05). Further, there was increase in antioxidant profile after TRP supplementation. Anti-inflammatory potentiality of TRP could also be appreciated since TRP supplementation downregulated (p ≤ 0.05) expression of IL-6, IL-1β, and IFN-γ. Therefore, we perceive that this conflated approach is an example of its own kind to focus on modification of health status of pigs for more productivity and augmentation of immune response.

    Abstract A reliable, pre-harvest, crop yield prediction based on meteorological factors is important to anticipate adverse effect of weather variables. Discriminant score-based regression models, MLP artificial neural network (ANN) models, and regression-ANN hybrid models were used to model potato (Solanum tuberosum L.) yield. Maximum and minimum temperatures, rainfall, and relative humidity, and their indices, were used to obtain discriminant scores for each year. These discriminant scores, along with a time variable, were used as inputs and potato yield as outputs for the development of models. A hybrid model consisting of linear and non-linear components performed better than individual models if combined linearity and nonlinearity are present in the data, else the ANN models were better than regression models. The best models can be used to obtain a reliable forecast of potato yield at 6–8 weeks before harvest using meteorological data.

    Abstract Leptospirosis, a global reemerging zoonosis caused by the spirochete Leptospira, has severe human and veterinary implications. Cell wall hydrolase (LIC_10271) with LytM (peptidase M23) and LysM domains are found to be associated with various pathogenic bacteria. These domains regulate effects on extracellular matrix and biofilm components, which promote cell wall remodeling and pathogen dissemination in the host. In this study, we present the cloning, expression, purification, and characterization of LIC_10271. To determine the localization of LIC_10271 within the inner membrane of Leptospira, Triton X-114 subcellular fractionation and immunoblot studies were performed. Furthermore, r-LIC_10271 binds with peptidoglycan, lipopolysaccharide, and laminin in a dose-dependent manner. Analysis of the signal peptide, M23, and LysM domains revealed conservation primarily within the P1 group of Leptospira, which encompasses the most pathogenic species. Moreover, the presence of native-LIC_10271 in the inner membrane and the distribution of M23 and LysM domains across pathogenic strains indicates their potential involvement in the interaction between the host and Leptospira.

    Abstract During the last four decades, precisely from the early 1970s, U.S. foreign policy has played a dominant role in the U.S. political landscape. The current political discourse is predominantly marked by divided government, polarized politics and gridlock. Such a contentious political environment has proved to be detrimental for efficient and effective policy-making in foreign policy. There are significant factors that profoundly complicate the process of decision making and congressional-presidential relations. Partisan and ideological differences under the conditions of divided government are dominant in the current political process and in turn affect the prospects of legislative-executive consensus and dissension. Other factors such as media salience, public opinion, and electoral imperatives also complicate the dynamics of legislative-executive relations. In an era in which heightened political brinkmanship has enveloped Washington politics, continuum of consensus and dissension between Congress and the president on strategic foreign policy issues has virtually become a norm. This dissertation examines the dynamics of legislative-executive relations in two high politics U.S. foreign policy issue areas of treaty process and war powers. It appears that in contemporary U.S. foreign policymaking the trajectory of a continuum of legislative-executive consensus and dissension is a new normal and potentially irreversible, as Congress and the president try ardently to preserve their respective constitutional prerogatives. Empirical investigation across these two issue areas demonstrates a new era of a resurgent Congress marked by its greater assertive role and acting as a consequential player in the foreign policy domain. The passage of the War Powers Resolution in 1973 by Congress, overriding a presidential veto, has profound implications in the modern political landscape. It was a pivotal moment that permanently transformed the future road map of congressional-presidential relations. Since then the U.S. political system has been relentlessly experiencing an institutional power struggle in the foreign policy domain. Findings suggest that when Congress determines to confront the president and exercise its constitutional responsibilities it becomes very difficult for the president to overcome such congressional resistance. Interbranch competition has virtually created a consistent trajectory of a continuum of legislative-executive consensus and dissension in the foreign policy decision-making process.

    Abstract Mesenchymal stem cell is a potent tool for regenerative medicine against control of incurable diseases in human and animals. Diabetes mellitus is one such condition marked with the blood glucose is high due to lack of insulin (INS) hormone secreted by the pancreatic cells. Rare, but sporadic, cases of dysfunctional pancreatic cells in goat as well as the promises of stem cell therapy as an off-the-shelf medicine prompted us to explore the potential of adipose-derived goat mesenchymal stem cells (AD-MSCs) to transdifferentiate into pancreatic islet-like cells. We isolated, in vitro cultured, and characterized the AD-MSCs by expression of MSC-specific markers and differentiation into multiple mesodermal lineage cells. The characterized AD-MSCs were in vitro transdifferentiated into INS-producing islet-like cells using a cocktail of glucose, nicotinamide, activin-A, exendin-4, pentagastrin, retinoic acid, and mercaptoethanol in 3 weeks. The transdifferentiated islet-like cells demonstrated the expression of pancreatic endoderm-specific transcripts PDX1, NGN3, PAX6, PAX4, ISL1, and GLUT2 as well as protein expression of pancreatic and duodenal homeobox 1 (PDX1), INS, and Islets 1 (ISL1). The islet-like cells also demonstrated the significant glucose-dependent INS release with respect to the course of transdifferentiation regime. The study envisaged to create the building material for basic research into mechanism of glucose homeostasis, which may pave road for developments in diabetes drug discovery and regenerative therapies.
