Structure-guided discovery of a novel BTK inhibitor inducing apoptosis and G1 phase arrest in tumor cells.

Bruton's tyrosine kinase (BTK) is a pivotal component of multiple signaling pathways in hematopoietic cells and serves as a critical pharmacological target in B-cell malignancies. Despite the availability of clinically approved BTK inhibitors, therapeutic resistance and limited efficacy in certain patient populations necessitate the discovery of novel candidates. In this study, virtual high-throughput screening of the ZINC database was employed to identify potential BTK inhibitors.

From tissue architecture to clinical insights: Spatial transcriptomics in solid tumor studies.

Cancer is a highly heterogeneous disease, and its diagnosis, prognosis, and therapeutic responsiveness depend not only on genetic alterations but also on the intricate organization of cells within the tumor microenvironment (TME). Spatial transcriptomics-a suite of techniques that preserves the spatial context of gene expression in intact tissue-has revolutionized our ability to decipher tumor architecture and intercellular communication. This review provides an in-depth analysis of recent advancements in spatial transcriptomics technologies and their applications in solid tumor research.

Suppressing Phase Instability and Iodide Expulsion in Mixed-Halide Perovskites via Directed Hole Transfer and Defect Management.

Bandgap tunability in mixed-halide perovskite CsPb(BrI) nanocrystals (NCs) makes them appealing for multijunction solar cells and tunable optoelectronics. However, light-induced halide migration and phase segregation, primarily driven by hole trapping and surface defects, limit their practical utility. Holes oxidize iodide ions, while defects facilitate their diffusion, leading to phase segregation and iodide expulsion.

Objective: To investigate the measles virus (MeV) outbreak at a tertiary-care centre of northern India in 2023.

Methods: Probable and confirmed cases of measles presenting to from a tertiary hospital in Chandigarh, India, between January 01, 2023, and September 30, 2023, were defined using the WHO measles outbreak toolbox. Laboratory confirmation was based on positive IgM serology for measles.

The nucleolar granular component mediates genome-nucleolus interactions and establishes their repressive chromatin states.

Repressive chromatin domains often localize to the nuclear lamina or nucleolus. Although nucleolar-associated domains (NADs) have recently been mapped, their mechanisms of nucleolar association and functional significance remain unclear. Here, we show that nucleophosmin (NPM1), a factor located in the granular component of the nucleolus, mediates NAD association in mouse embryonic stem cells.

Healing with hierarchy: Hierarchical attention empowered graph neural networks for predictive analysis in medical data.

In healthcare, predictive analysis using unstructured medical data is crucial for gaining insights into patient conditions and outcomes. However, unstructured data, which contains valuable patient information such as symptoms and medical histories, often presents challenges, including lengthy text sequences and incomplete data. To address these issues, we introduce a new framework named Hierarchical Attention-based Integrated Learning (HAIL), designed to predict in-hospital mortality and the duration of stay in the intensive care unit.

Antitumor potential of ivermectin against T-cell lymphoma-bearing hosts.

Ivermectin, a broad-spectrum antiparasitic agent from the ivermectin family, has shown promising anticancer potential. Originally developed for veterinary and human use against parasitic infections, ivermectin demonstrated significant antitumor effects in our study against tumor cells (Dalton's lymphoma cells). A dose-dependent decrease in tumor cell viability was observed following 24-h treatment with ivermectin, with an IC₅₀ value calculated at 10.

Dual-locking strategy with a charge-delocalizing ligand for stable perovskites.

We developed a multifunctional phenyl bis(dithiocarbamate) (PBTC) ligand that enhances perovskite nanocrystal stability under UV exposure and in polar solvents through strong lead chelation and intrinsic UV absorption. Its hole-delocalizing properties suppress phase segregation, making it a promising candidate for photovoltaics and light-emitting diodes.

Determinants for Substoichiometric Inhibition of IAPP and Aβ Amyloid Aggregations by Bri2 BRICHOS.

Bri2 BRICHOS, a folded domain of the transmembrane protein Bri2 expressed in both the brain and pancreas, is an experimentally known substoichiometric inhibitor of amyloid aggregation. The molecular chaperone effectively delays fibrillization at low molar ratios for both β-amyloid (Aβ) in Alzheimer's disease (AD) and islet amyloid polypeptide (IAPP) in type 2 diabetes (T2D). While discovering effective antiamyloid inhibitors that work at low doses is an appealing strategy to mitigate amyloid toxicity, the molecular mechanism underlying the broad and efficient antiamyloid activity of Bri2 BRICHOS remains unknown.

From development to clinical success: the journey of established and next-generation BTK inhibitors.

Over the past decade, Bruton's tyrosine kinase (BTK) has emerged as a pivotal therapeutic target for B-cell malignancies and autoimmune diseases, given its essential role in B-cell development and function. Dysregulation of BTK signalling is implicated in a range of hematologic cancers, including Waldenström's macroglobulinaemia (WM), mantle cell lymphoma (MCL), and chronic lymphocytic leukaemia (CLL). The development of BTK inhibitors (BTKIs), starting with ibrutinib, has revolutionized the treatment of these malignancies by inhibiting B-cell receptor (BCR) signalling and inducing apoptosis in malignant B-cells.

Perovskite-Molecular Photocatalyst Synergy and Surface Engineering for Superior Photocatalytic Performance.

Metal halide perovskite nanocrystals (NCs), known for their strong visible-light absorption and tunable optoelectronic properties, show significant promise for photocatalytic applications. However, their efficiency is often hindered by rapid charge recombination and insufficient exciton dissociation, limiting effective catalysis. Excited-state interactions at the NC interface are critical in determining photocatalytic performance, underscoring the need for strategies that enhance charge separation and minimize recombination.

Primer on disability: Why accessibility is important for all medical physicists.

Disability and accessibility remain under-addressed topics despite the increasing prevalence of disabled people in the workforce. In the field of medical physics, there is growing evidence that the proportion of people with one or more disabilities mirrors that of the US population. Addressing disability and accessibility is a crucial facet of the American Association of Physicists in Medicine's 2018 strategic goal to "champion equity, diversity, and inclusion in the field of medical physics.

Role of stomatal and leaf anatomical features in defining plant performance under elevated carbon dioxide and ozone, in the changing climate scenario.

This research investigates the interactive effects of elevated ozone (eO) and carbon dioxide (eCO) on stomatal morphology and leaf anatomical characteristics in two wheat cultivars with varying O sensitivities. Elevated O increased stomatal density and conductance, causing oxidative stress and cellular damage, particularly in the O-sensitive cultivar PBW-550 (PW), compared to HUW-55 (HW). Conversely, eCO reduced stomatal density and pore size, mitigating O-induced damage by limiting O influx.
