Temporal effect of flaxseed oil in boar's diet on semen quality, antioxidant status and in-vivo fertility under hot humid sub-tropical condition.

The present study investigates the temporal effects of flaxseed supplementation on boar semen quality, antioxidant status, and in-vivo fertility under high-temperature humidity index (THI) conditions in a sub-tropical climate. Twelve Hampshire crossbreed boars were randomly assigned to control and treatment groups, with the treatment group receiving flaxseed oil supplementation. Semen samples were collected and analyzed for semen quality parameters, sperm kinematics, and antioxidant status.

Indigenous chicken production system in different agro-ecology of Indian Himalayan Region: implication on food and economic security.

The indigenous chicken production system (ICPS) has several use values and ecosystem services. In the last few years, ICPS has been recognized for its possible contribution to household food security, income generation, wildlife protection, and bettering the women's lives. This study aimed to collect, for the first time, comprehensive information about ICPS in three different agro-ecologies (tropical, sub-tropical, and sub-temperate) of the Indian Himalayan Region (IHR) and its role in food and economic security of traditional communities.

Common scab disease-induced changes in geocaulosphere microbiome assemblages and functional processes in landrace potato (Solanum tuberosum var. Rongpuria) of Assam, India.

Common scab (CS) caused by pathogenic Streptomyces spp. plays a decisive role in the qualitative and quantitative production of potatoes worldwide. Although the CS pathogen is present in Assam's soil, disease signs and symptoms are less obvious in the landrace Rongpuria potatoes that indicate an interesting interaction between the plant and the geocaulosphere microbial population.

Rotational synchronization of pinned spiral waves.

Coupled rotors can spontaneously synchronize, giving rise to a plethora of intriguing dynamics. We present here a pair of spiral waves as two synchronizing rotors, coupled by diffusion. The spirals are pinned to unexcitable obstacles, which enables us to modify their frequencies and restrain their drift.

Interaction of multiple spiral rotors in a reaction-diffusion system.

Rotors of reaction and diffusion are phase singularities that give rise to spiral waves of chemical activity, which are very similar to spatiotemporal patterns observed across several excitable media. Here we carry out experiments with the Belousov-Zhabotinsky reaction system and numerical simulations based on a reaction-diffusion model to show the possible interactions of multiple spiral rotors. When the cores of two spirals come very close to each other, they could either repel, attract, or remain stationary, depending on their relative chirality, phase, and distance separating them.

Strategies for Deploying a Sensor Network to Explore Planetary Lava Tubes.

Recently discovered pits on the surface of the Moon and Mars are theorized to be remnants of lava tubes, and their interior may be in pristine condition. Current landers and rovers are unable to access these areas of high interest. However, multiple small, low-cost robots that can utilize unconventional mobility through ballistic hopping can work as a team to explore these environments.

Size matters! The largest wild stump-tailed macaque troop ever reported, located in the Hollongapar Gibbon Sanctuary, northeastern India.

Very large and stable, socially coherent primate groups, not including fission-fusion societies, are usually rare in nature, owing to constraints imposed by various ecological and social factors. Moreover, unlike species in open habitats, those in forests tend to have smaller groups, and this becomes further accentuated in small and fragmented forest patches. We report here an unusually large troop of stump-tailed macaques from the Hollongapar Gibbon Sanctuary, a small and isolated lowland tropical rainforest patch in the Upper Brahmaputra Valley of northeastern India - this is possibly the largest wild group of the species recorded anywhere across its distribution range.

Withdrawal of High-Carbohydrate, High-Fat Diet Alters Status of Trace Elements to Ameliorate Metabolic Syndrome in Rats With Type 2 Diabetes Mellitus.

Objectives: Inadequate nutrient supply and insulin resistance contribute to the pathogenesis of metabolic syndrome (MetS) and increase the risk of developing cardiovascular disease. MetS can be induced by prolonged feeding of a high-carbohydrate, high-fat (HCHF) diet. The present study was designed using Wistar albino rats as an experimental model to investigate the effect of subchronic withdrawal of an HCHF diet during MetS on distribution of copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), zinc (Zn) and chromium (Cr) in different biological media.

Uniform Vapor-Pressure-Based Chemical Vapor Deposition Growth of MoS Using MoO Thin Film as a Precursor for Coevaporation.

Chemical vapor deposition (CVD) is a powerful method employed for high-quality monolayer crystal growth of 2D transition metal dichalcogenides with much effort invested toward improving the growth process. Here, we report a novel method for CVD-based growth of monolayer molybdenum disulfide (MoS) by using thermally evaporated thin films of molybdenum trioxide (MoO) as the molybdenum (Mo) source for coevaporation. Uniform evaporation rate of MoO thin films provides uniform Mo vapors which promote highly reproducible single-crystal growth of MoS throughout the substrate.

Development of banana () pseudo stem fiber as a surgical bio-tool to avert post-operative wound infections.

The search to develop an ideal suture material encourages us to explore novel suture biomaterials with superior characteristics to the current commercially available products. Surgical sutures play a crucial role in the development of post-operative wound infection by acting as a substrate for biofilm formation which leads to dehisced wounds. In this context, the present invention meets this need by fabricating banana () fibre into an advanced antimicrobials releasing suture biomaterial (BSc) for the prevention of post-operative wound infection.

An information, education and communication module to reduce dietary salt intake and blood pressure among tea garden workers of Assam.

Objective: High salt diet increases blood pressure. Tea garden workers (TGW) of Assam, India have high (60.8%) prevalence of hypertension (HTN), which may be due to consumption of extra salt (salt as side dish) and salted tea at work place and home.

Correlations between preparation methods, structural features and electrochemical Li-storage behavior of reduced graphene oxide.

Wide differences in the structural features of graphenic carbon, especially in the case of reduced graphene oxides (rGO), are expected to have considerable impacts on the properties, thus leading to significant scatter and poor understanding/prediction of their performances for various applications, including as electrode materials for electrochemical Li-storage. In this context, the present work develops a comprehensive understanding (via thorough experimentation, including in situ X-ray diffraction studies, and analysis) on the effects of graphene oxide (GO) reduction methods/conditions on the structural features (mainly 'graphenic' ordering) and concomitant influences of the same on electrochemical Li-storage behavior. 'Moderately oxidized' GO (O/C ∼0.

Withdrawal from high-carbohydrate, high-saturated-fat diet changes saturated fat distribution and improves hepatic low-density-lipoprotein receptor expression to ameliorate metabolic syndrome in rats.

Objective: The "lipid hypothesis" determined that saturated fatty acid (SFA) raises low-density lipoprotein cholesterol, thereby increasing the risk for metabolic syndrome (MetS). The aim of this study was to investigate the effect of subchronic withdrawal from a high-carbohydrate, high-saturated fat (HCHF) diet during MetS with reference to changes in deleterious SFA (C12:0, lauric acid; C14:0, myristic acid; C16:0, palmitic acid; C18:0, stearic acid) distribution in liver, white adipose tissue (WAT), and feces.

Methods: MetS induced by prolonged feeding of an HCHF diet in Wistar albino rat is used as a model of human MetS.
