This study focused on two aspects: to develop a selected functionally competent bacterial community, and its integrated with biostimulant humic acid and seaweed extract which was validated to enhance wheat growth and nutrient content. Wheat and maize-associated bacterial isolates (92) were screened for Plant Growth-Promoting traits (PGPts-72) and Community-Forming traits (CFts-66). 46 isolates possessed both kinds of traits, of which 20 isolates were chosen based on high Bonitur scale ratings.

Root resorption is a challenging endodontic case in terms of the management of both hard and soft tissues in patients. It requires thorough knowledge, the proper choice of material, and regular follow-ups. Several etiological factors are responsible for the susceptibility of the tooth to resorption.

Fluorosis is a widespread condition that is endemic and found in approximately 25 nations worldwide. It manifests as dental fluorosis, an inherited enamel imperfection resulting from excessive fluoride exposure during tooth development. This condition can lead to varying degrees of tooth discoloration, often requiring aesthetic correction.

Objectives: This study assessed overall quality of life (QoL) over time in youth with cleft lip and palate (CLP) undergoing maxillary protraction treatment or orthognathic surgery for class III malocclusion to identify any differences in QoL based on treatment group and outcome success.

Materials And Methods: A prospective longitudinal cohort study was conducted in two pediatric hospitals. The Short Form Health Survey (SF-12) measured physical and mental QoL prior to treatment, at maximal correction, at treatment completion, and at 1-year post treatment.

As periodontal and endodontic tissues have a close association, they come into close touch and have a lot of possible places for communication. In a clinical setting, this correlation promotes infection spread and results in the typical endo-perio lesion appearance. Because the two tissues are in close touch with one another, managing such lesions can be difficult.

Intense cultivation with narrow row spacing in wheat, a common practice in the Indo-Gangetic plains of South Asia, renders the crop more susceptible to lodging during physiological maturity. This susceptibility, compounded by the use of traditional crop cultivars, has led to a substantial decline in overall crop productivity. In response to these challenges, a two-year field study on the system of wheat intensification (SWI) was conducted.

Article Synopsis
  • - Templated ligation is an efficient method for replicating long RNA strands using a prebiotically available activation, specifically the 2',3'-cyclic phosphate, which forms during RNA breakdown.
  • - Research shows that this ligation process can occur in simple conditions (low-salt, alkaline pH, and moderate temperatures) without needing additional catalysts, leading to a 50% increase in canonical linkages compared to past studies.
  • - The reaction is sequence-specific with high fidelity rates, enabling the successful creation of longer RNA strands, which may indicate how ribozymes could have assembled on early Earth.

Fluorescence-based biological imaging in the shortwave infrared (SWIR, 1000-1700 nm) is an attractive replacement for modern imaging techniques currently employed in both medical and research settings. Xanthene-based fluorophores containing heterocycle donors have recently emerged as a way to access deep SWIR emitting fluorophores. A concern for xanthene-based SWIR fluorophores though is chemical stability toward ambient nucleophiles due to the high electrophilicity of the cationic fluorophore core.

Gold nanoparticles (AuNPs) synthesized in the 1-3 nm range have a specific number of gold core atoms and outer protecting ligands. They have become one of the "hot topics" in recent decades because of their interesting physical and chemical properties. The characterization of their structures is usually achieved by crystal X-ray diffraction although the structures of some AuNPs remain unknown because they have not been successfully crystallized.

Sensor-based decision tools provide a quick assessment of nutritional and physiological health status of crop, thereby enhancing the crop productivity. Therefore, a 2-year field study was undertaken with precision nutrient and irrigation management under system of crop intensification (SCI) to understand the applicability of sensor-based decision tools in improving the physiological performance, water productivity, and seed yield of soybean crop. The experiment consisted of three irrigation regimes [I: standard flood irrigation at 50% depletion of available soil moisture (DASM) (FI), I: sprinkler irrigation at 80% ET (crop evapo-transpiration) (Spr 80% ET), and I: sprinkler irrigation at 60% ET (Spr 60% ET)] assigned in main plots, with five precision nutrient management (PNM) practices{PNM-[SCI protocol], PNM-[RDF, recommended dose of fertilizer: basal dose incorporated (50% N, full dose of P and K)], PNM-[RDF: basal dose point placement (BDP) (50% N, full dose of P and K)], PNM-[75% RDF: BDP (50% N, full dose of P and K)] and PNM-[50% RDF: BDP (50% N, full P and K)]} assigned in sub-plots using a split-plot design with three replications.

According to definition and general agreement, smart materials have properties that can be altered in a controlled fashion by stimuli including stress, temperature, moisture, pH, and electric or magnetic fields. Various recent materials in materials science are in working order, meaning they must achieve their tasks and should go through intentional modification. Smart materials change one or more of their characteristics in response to inputs.

Purpose: Although pivotal trials have demonstrated efficacy of anti-vascular endothelial growth factor therapy in neovascular age-related macular degeneration, there is a paucity of clinical data about the long-term (>5 years) treatment.

Methods: Retrospective analysis of all patients with neovascular age-related macular degeneration who were actively treated, had received >40 anti-vascular endothelial growth factor injections, and were followed for ≥5 years. Snellen-corrected visual acuity, initial drug choice, and times elapsed between treatments were collected.

The coronavirus disease 2019 (COVID-19) pandemic has deteriorated the healthcare system and economy worldwide. Globally, by making the primary vaccination against the coronavirus necessary, the surge in cases waned, but as the effects of this vaccination decreased after some time, to prevent another pandemic, vaccination was still necessary. As a result, receiving a COVID-19 booster shot can boost immunity against the coronavirus.

The rice-maize system is a dominant cropping system of south Asia and consumes a considerable amount of fertilizer. The indiscriminate use of fertilizer particularly nitrogen (N) is degrading the soil health and polluting the environment. Lower N-use efficiency is a major problem and needs to be improved for higher yield, lower cost of cultivation and better environment.

The continuing decline in water resources under the ever-changing climate compels us to re-orient our focus to a more sustainable practice. This study investigates the performance of wheat genotypes viz. HD-2967, HD-3086, HD-3249, DBW-187, and HD-3226 under well- and deficit-watered conditions for their root-traits, biomass and nitrogen accumulation and remobilization, and water use efficiencies, grown in PVC-tubes.

Article Synopsis
  • Delayed sowing of maize hybrids can lead to lower yields due to poor root growth, nutrient uptake, and dry matter accumulation.
  • In a study comparing five maize hybrids, timely sowing resulted in 16-19% higher grain yields and 12-25% higher stover yields compared to late sowing.
  • Advanced hybrids AH-4271 and AH-4158 performed best in terms of grain yield, nutrient efficiency, and root growth, emphasizing the importance of sowing time and hybrid selection for maximizing maize productivity.

Chloroplasts have evolved from photosynthetic cyanobacteria-like progenitors through endosymbiosis. The chloroplasts of present-day land plants have their own transcription and translation systems that show several similarities with prokaryotic organisms. A remarkable feature of the chloroplast translation system is the use of non-AUG start codons in the protein synthesis of certain genes that are evolutionarily conserved from Algae to angiosperms.
