Salmonella Typhimurium effector SseI regulates host peroxisomal dynamics to acquire lysosomal cholesterol.

Salmonella enterica serotype Typhimurium (Salmonella) resides and multiplies intracellularly in cholesterol-rich compartments called Salmonella-containing vacuoles (SCVs) with actin-rich tubular extensions known as Salmonella-induced filaments (SIFs). SCV maturation depends on host-derived cholesterol, but the transport mechanism of low-density lipoprotein (LDL)-derived cholesterol to SCVs remains unclear. Here we find that peroxisomes are recruited to SCVs and function as pro-bacterial organelle.

Assessment of Dental Anxiety in a Young Population of the North Indian City of Lucknow.

Introduction: Dental anxiety is a common fear, especially among younger age groups, and it can prevent individuals from seeking necessary dental treatment. Effective communication between dental professionals and young adults is crucial to address this issue. However, factors such as past experiences, peer influences, and coping strategies can impact a young adult's anxiety in a dental setting.

Combined HDAC8 and checkpoint kinase inhibition induces tumor-selective synthetic lethality in preclinical models.

The elevated level of replication stress is an intrinsic characteristic of cancer cells. Targeting the mechanisms that maintain genome stability to further increase replication stress and thus induce severe genome instability has become a promising approach for cancer treatment. Here, we identify histone deacetylase 8 (HDAC8) as a drug target whose inactivation synergized with the inhibition of checkpoint kinases to elicit substantial replication stress and compromise genome integrity selectively in cancer cells.

A panoptic segmentation dataset and deep-learning approach for explainable scoring of tumor-infiltrating lymphocytes.

Tumor-Infiltrating Lymphocytes (TILs) have strong prognostic and predictive value in breast cancer, but their visual assessment is subjective. To improve reproducibility, the International Immuno-oncology Working Group recently released recommendations for the computational assessment of TILs that build on visual scoring guidelines. However, existing resources do not adequately address these recommendations due to the lack of annotation datasets that enable joint, panoptic segmentation of tissue regions and cells.

Comparing the Clinical Orientation Benefits of Endoscopic demonstration on the Nose, Paranasal Sinuses, and Skull Base Versus Cadaveric Dissection for First-Year Medical Undergraduates.

The study aims to evaluate the advantages of using endoscopic demonstrations to teach nose, paranasal sinuses, and skull base anatomy compared to traditional cadaveric demonstrations. Traditional dissection methods do not provide an accurate representation of in vivo visualization of these anatomical areas. The goal is to align the teaching approach with the perspective students will have during clinical practice for better clinical orientation.

Deletion of Dictyostelium tpc2 gene forms multi-tipped structures, regulates autophagy and cell-type patterning.

Background Information: Two pore channels (TPCs) are voltage-gated ion channel superfamily members that release Ca from acidic intracellular stores and are ubiquitously present in both animals and plants. Starvation initiates multicellular development in Dictyostelium discoideum. Increased intracellular calcium levels bias Dictyostelium cells towards the stalk pathway and thus we decided to analyze the role of TPC2 in development, differentiation, and autophagy.
