Background And Objective: We evaluated the DR-TB component of the National Tuberculosis Elimination Program (NTEP) in a high-burden district in Kerala to identify the programmatic gaps, if any, in screening, diagnosis, treatment, and follow-up of notified DR-TB patients.

Methods: A mixed-methods design was used, and the evaluation was performed in two steps. In the first step, we reviewed the program documents and conducted stakeholder interviews to develop a detailed description of the program design and developed a logical framework to evaluate program performance.

Dipeptides were constructed using hydrophobic amino acid residues following AMP prediction. After that Boc-modification was performed on the screened peptides and finally Boc-Phe-Trp-OMe and Boc-Trp-Trp-OMe were synthesized. Even though no inhibition zones were observed in agar well diffusion assays, minimum inhibitory concentration (MIC) analysis revealed anti-bacterial activity against both Gram-positive and Gram-negative bacteria, with MIC ranging from 230 to 400 μg/mL.

December 2024

Facultad de Medicina Veterinaria y Zootecnia, Universidad Autónoma del Estado de México, El Cerrillo Piedras Blancas, 50295, Toluca, Estado de México, Mexico.

Reducing greenhouse gas (GHG) emissions from livestock is a crucial step towards mitigating the impact of climate change and improving environmental sustainability in agriculture. This study aimed to evaluate the effects of Yucca schidigera extract, chitosan, and chitosan nanoparticles as feed additives on in vitro GHG emissions and fermentation profiles in ruminal fluid from bulls. Total gas, CH, CO, and HS emissions (up to 48 h), rumen fermentation profiles, and CH conversion efficiency were measured using standard protocols.

Reversibly crosslinked polymer networks - polymer networks that can undergo bond association and dissociation reactions - rearrange their structures while maintaining their overall integrity, thus resulting in unique properties such as self-healing, reprocessability, shape memory and adaptability. Here, we show that the introduction of crosslinks, whether reversible or permanent, directly impacts the equilibrium polymer density and hence the material's surface tension. For a limiting case where the bonds are the same size as the polymer chain bonds, simulations, Flory hypotheses and thermodynamic calculations show that the crosslinks induce an increased entropic cohesion in the liquid.

The synthesis of polymer/oligomer-stabilized metal nanostructures (MNS) opens up a wide range of possibilities, from fundamental materials science to practical applications in domains such as medicine, catalysis, sensing, and energy. Because of the versatility of this synthetic approach, it is a dynamic and ever-changing field of study. These polymers/oligomers have precise control over the nucleation and growth kinetics, allowing the production of mono-disperse MNS with well-defined properties.

Twin pregnancies consisting of one normal fetus and one complete mole are very rare. The main concerning risks associated with the continuation of such pregnancy are hyperthyroidism, theca lutein cysts, preeclampsia, and the development of GTD (gestational trophoblastic disease) spectrum (neoplasia) in the mother, which is due to high human chorionic gonadotropin (HCG) values, and intrauterine death and prematurity in the coexistent normal fetus. We report the successful outcome of conservative management in a healthy mother and baby.

The increasing prevalence of chronic diseases and their associated morbidities demands a deeper understanding of underlying mechanism and causative factors, with the hope of developing novel therapeutic strategies. Autophagy, a conserved biological process, involves the degradation of damaged organelles or protein aggregates to maintain cellular homeostasis. Disruption of this crucial process leads to increased genomic instability, accumulation of reactive oxygen species (ROS), decreased mitochondrial functions, and suppression of ubiquitination, leading to overall decline in quality of intracellular components.
