Biosafety and Withdrawal Period of In-Feed Administered Antiparasitic Drug Emamectin Benzoate in Cirrhinus mrigala (Hamilton, 1822).

Parasitic infestations are one of the most economically important disease conditions in the Indian major carps including mrigal, Cirrhinus mrigala. This study reported the biosafety and tissue withdrawal of in-feed administered antiparasitic drug, emamectin benzoate (EMB). To evaluate the biosafety of the drug, behaviour, growth and tissue changes in Cirrhinus mrigala was recorded the following in-feed administration of EMB up to 10 times (T1-50 μg kg fish day (1×), T2-125 μg kg fish day (2.

Trastuzumab Deruxtecan Combination Strongly Enhances Responses and Overcomes Sotorasib Resistance in -Mutant NSCLC.

Introduction: Recent advances in the treatment of -mutant non-small cell lung cancer (NSCLC) have led to the development of KRAS inhibitors, such as sotorasib and adagrasib. However, resistance and disease progression remain significant challenges. In this study, we investigated the therapeutic potential of combining trastuzumab deruxtecan (T-DXd), an anti-HER2 antibody-drug conjugate, with sotorasib in -mutant NSCLC, while also evaluating HER2 expression in NSCLC samples.

Field-Induced Antiferromagnetic Correlations in a Nanopatterned Van der Waals Ferromagnet: A Potential Artificial Spin Ice.

Nano-patterned magnetic materials have opened new venues for the investigation of strongly correlated phenomena including artificial spin-ice systems, geometric frustration, and magnetic monopoles, for technologically important applications such as reconfigurable ferromagnetism. With the advent of atomically thin 2D van der Waals (vdW) magnets, a pertinent question is whether such compounds could make their way into this realm where interactions can be tailored so that unconventional states of matter can be assessed. Here, it is shown that square islands of CrGeTe vdW ferromagnets distributed in a grid manifest antiferromagnetic correlations, essential to enable frustration resulting in an artificial spin-ice.

Burden and challenges in managing TB infection among people with occupational exposure to silica in India.

Background: Occupational exposure to silica increases the risk of TB infection (TBI) and disease. This study aimed to determine the prevalence of TBI and explore challenges in TBI management in such individuals in two districts of India during 2023.

Methods: This was an explanatory mixed-methods study with a quantitative cohort design and qualitative descriptive in-depth interviews.

EGFR-mediated HSP70 phosphorylation facilitates PCNA association with chromatin and DNA replication.

Efficient DNA replication requires highly coordinated programs for the timely recruitment of protein complexes to DNA replication forks. Defects in this process result in replication stress, which in turn activates cell cycle checkpoints, suppresses cell proliferation and induces apoptosis. In response to persistent cell growth signals that speed up DNA replication processes, cells accelerate the recruitment of DNA replication proteins to avoid DNA replication stress.
