Unraveling the genetic diversity, population structure, and stability for yield-related traits of rice genotypes in mid-hills of northeastern India.

The cultivation of nearly 10,000 indigenous rice landraces in the North-Eastern Hill (NEH) region by various ethnic groups creates opportunities for the utilization of unique landraces through systematic evaluation of genetic variability. In the present study, a set of 102 rice landraces were assessed based on morphological and SSR markers, and five checks in augmented design vis-à-vis high-yielding rice genotypes with stable performance were identified. The presence of high estimates of heritability, genotypic coefficient of variation, and genetic advance over mean indicated the predominance of additive gene action, which necessitated the effectiveness of selection in augmenting productivity.

Oxyrase-Mediated Improvement in the Quality and Fertility of Crossbred Boar Spermatozoa During Liquid Storage.

The present experiment was carried out to investigate the role of Oxyrase in preserving the in vitro quality, redox status and in vivo fertility of crossbred boar spermatozoa. A total of 24 ejaculates from 6 crossbred (n = 4 from each boar) boars were collected and extended in Beltsville Thawing Solution (BTS) in 1:2 ratio and divided into three aliquots. The first aliquot served as a control (without Oxyrase).

Copper-catalyzed synthesis of pyrazolo[1,5-a]pyrimidine based triazole-linked glycohybrids: mechanistic insights and bio-applications.

Hybrid molecules maintain their stronghold in the drug market, with over 60% of drug candidates in pharmaceutical industries. The substantial expenses for developing and producing biologically privileged drugs are expected to create opportunities for producing hybrid molecule-based drugs. Therefore, we have developed a simple and efficient copper-catalyzed approach for synthesizing a wide range of triazole-linked glycohybrids derived from pyrazolo[1,5-a]pyrimidines.

Synthesis of triazole bridged -glycosides of pyrazolo[1,5-]pyrimidinones as anticancer agents and their docking studies.

In the pursuit of novel therapeutic agents, we present a comprehensive study on the design, synthesis, and evaluation of a diverse library of triazole bridged -glycosides of pyrazolo[1,5-]pyrimidinones, employing a microwave-assisted synthetic approach 'click chemistry'. This methodology offers efficient and accelerated access to the glycohybrids, showcasing improved reaction conditions that yield high-quality products. In this research endeavor, we have successfully synthesized a series of twenty-seven triazole bridged -glycosides of pyrazolo[1,5-]pyrimidinones.

Rationalizing mineral gypsum use through microbially enriched municipal solid waste compost for amelioration and regaining productivity potential of degraded alkali soils.

Reclamation of alkali soils to harness their productivity potential is more complex due to the presence of excess sodium ions, poor hydraulic conductivity and infiltration rate, resulting in poor plant growth and crop productivity. Sodic soil reclamation using inorganic ameliorants like mineral gypsum or phosphogypsum is beyond the reach of small and marginal farmers having alkali soils because of their higher market prices and shortage of availability. Conjoint use of inorganic and organic amendments can be a pragmatic solution for improving soil physico-chemical and biological properties and sustaining crop productivity.

Evaluation of millets for physio-chemical and root morphological traits suitable for resilient farming and nutritional security in Eastern Himalayas.

Introduction: Millets are nutritionally superior and climate-resilient short-duration crops and hold a prominent place in cropping sequences around the world. They have immense potential to grow in a marginal environment due to diverse adaptive mechanisms.

Methods: An experiment was conducted in an organic production system in the North Eastern Himalayan foothills of India for 3 consecutive years by evaluating high-yielding varieties (HYVs) of different millets, viz.

Electro-organic green synthesis of dicyano-2-(2-oxoindolin-3-ylidene) malononitriles using molecular iodine as catalyst.

The first electrochemical molecular iodine promoted, domino reactions for the green synthesis of biologically relevant dicyano 2-(2-oxoindolin-3-ylidene) malononitriles (11 examples, up to 94% yield) from readily available isatin derivatives, malononitrile, and iodine at room temperature have been presented. This synthesis method showed tolerance towards various EDG and EWG and was completed in a short reaction time at the constant low current density of 5 mA cm in the low redox potential range of -0.14 to 0.

Biochemical and antioxidant activity of wild edible fruits of the eastern Himalaya, India.

The eastern Himalayas, one of the important hotspots of global biodiversity, have a rich diversity of wild edible fruit trees. The fruits of these tree species have been consumed by the tribal people since time immemorial. However, there is limited information available on the biochemical and antioxidant properties of the fruits.

Linseed oil in boar's diet improved in vivo fertility and antioxidant status.

The reactive oxygen species (ROS) which are produced during storage of boar semen are causing oxidative stress and leads to poor fertility. Also, tropical and sub-tropical weather condition adversely impacts the physicomorphological quality and fertility of boar sperm. The aim of this study was to examine the effects of feeding linseed oil to boar on its seminal attributes, sperm kinetics, biomarkers of antioxidant, fatty acid profile of seminal plasma (SP) and sperm and in vivo fertility.

Fluoride in the environment and its metabolism in humans.

The presence of environmental fluoride and its impact on human health is well documented. When consumed in adequate quantity, fluoride prevents dental caries, assists in the formation of dental enamels, and prevents deficiencies in bone mineralization. At excessive exposure levels, ingestion of fluoride causes dental fluorosis skeletal fluorosis, and manifestations such as gastrointestinal, neurological, and urinary problems.
