Dynamic gene expression pattern in zebrafish gall bladder - an experimental study.

Gall bladder cancer (GBC) is one of the common biliary tract malignancies that is often associated with late presentation of clinical symptoms resulting in poor prognosis, thereby considerably increasing the mortality rate. Geographic and ethnic variations are one of the major causes of GBC incidence. However, in addition to genetic susceptibility to GBC, other factors like age, obesity, gender, and exposure to certain heavy chemicals may also lead to the incidence of GBC.

Microarray integrated spatial transcriptomics (MIST) for affordable and robust digital pathology.

10X Visium, a popular Spatial transcriptomics (ST) method, faces limited adoption due to its high cost and restricted sample usage per slide. To address these issues, we propose Microarray Integrated Spatial Transcriptomics (MIST), combining conventional tissue microarray (TMA) with Visium, using laser-cutting and 3D printing to enhance slide throughput. Our design facilitates independent replication and customization in individual labs to suit specific experimental needs.

Universal correlation for the critical diameter of deterministic lateral displacement devices with polygonal posts.

Deterministic lateral displacement (DLD) is a microfluidic technique that utilizes a specific array of micro-posts to separate cells or particles larger and smaller than a critical diameter. The critical diameter depends on the shape of the posts, the gap between the posts, and the relative shift between the adjacent rows of posts. Here, we present an experimental and numerical investigation to elucidate the functional dependence of the critical diameter of DLD arrays with polygonal posts on the geometric parameters.

RNA Pol II Assembly Affects ncRNA Expression.

RNA pol II assembly occurs in the cytoplasm before translocation of the enzyme to the nucleus. Affecting this assembly influences mRNA transcription in the nucleus and mRNA decay in the cytoplasm. However, very little is known about the consequences on ncRNA synthesis.

DNA-binding protein PfAP2-P regulates parasite pathogenesis during malaria parasite blood stages.

Malaria-associated pathogenesis such as parasite invasion, egress, host cell remodelling and antigenic variation requires concerted action by many proteins, but the molecular regulation is poorly understood. Here we have characterized an essential Plasmodium-specific Apicomplexan AP2 transcription factor in Plasmodium falciparum (PfAP2-P; pathogenesis) during the blood-stage development with two peaks of expression. An inducible knockout of gene function showed that PfAP2-P is essential for trophozoite development, and critical for var gene regulation, merozoite development and parasite egress.

Prevalence of Workplace Violence and Effects of De-escalation Training Among Hospitalists: A Pilot Study.

Introduction: Workplace violence (WPV) is increasing in healthcare and negatively impacts healthcare worker outcomes. De-escalation training for healthcare workers is recommended to reduce WPV from patients and visitors. Hospitalists may be at high risk for WPV, but the magnitude of WPV and the impact of de-escalation training among hospitalists is not known.

Identification of herpesvirus transcripts from genomic regions around the replication origins.

Long-read sequencing (LRS) techniques enable the identification of full-length RNA molecules in a single run eliminating the need for additional assembly steps. LRS research has exposed unanticipated transcriptomic complexity in various organisms, including viruses. Herpesviruses are known to produce a range of transcripts, either close to or overlapping replication origins (Oris) and neighboring genes related to transcription or replication, which possess confirmed or potential regulatory roles.

A systematic comparison of human mitochondrial genome assembly tools.

Background: Mitochondria are the cell organelles that produce most of the chemical energy required to power the cell's biochemical reactions. Despite being a part of a eukaryotic host cell, the mitochondria contain a separate genome whose origin is linked with the endosymbiosis of a prokaryotic cell by the host cell and encode independent genomic information throughout their genomes. Mitochondrial genomes accommodate essential genes and are regularly utilized in biotechnology and phylogenetics.

In contrast to prior literature, our study assesses both satisfaction and the importance of various factors. This study examines morale of hospitalists early in the COVID-19 pandemic in two settings: conventional hospitals and a COVID-19 Alternate Care site (ACS) in the same geographic region in Maryland.

A Novel Robust Method Mimicking Human Substratum To Dissect the Heterogeneity of Candida auris Biofilm Formation.

Candida auris is a pathogen of urgent threat level as marked by the CDC. The formation of biofilms is an essential property of this fungus to establish infection and escape drug treatment. However, our understanding of pathogenesis through biofilm is hampered by heterogeneity in C.

PfAP2-MRP DNA-binding protein is a master regulator of parasite pathogenesis during malaria parasite blood stages.

Malaria pathogenicity results from the parasite's ability to invade, multiply within and then egress from the host red blood cell (RBC). Infected RBCs are remodeled, expressing antigenic variant proteins (such as PfEMP1, coded by the gene family) for immune evasion and survival. These processes require the concerted actions of many proteins, but the molecular regulation is poorly understood.
