Osteoclast visualization: Tartrate-resistant acid phosphatase activity staining using NewFuchsin compatible with non-aqueous mounting and tissue clearing.

Tartrate-resistant acid phosphatase (TRAP) staining is widely used to stain osteoclasts in histological bone sections. The red dye formed by the conventional TRAP enzymatic reaction using naphthol AS-MX (or AS-BI) phosphate and fast red-violet (or garnet) chromogens is readily soluble in alcohol or xylene and requires air-drying prior to cover slipping or the use of an aqueous mounting medium. However, the use of an aqueous mounting medium makes it difficult to store stained specimens for a long time.

Chemokine associations with blood cerebrospinal fluid (CSF) barrier permeability and delirium.

Delirium is a highly prevalent neuropsychiatric syndrome characterised by acute and fluctuating impairments in attention and cognition. Mechanisms driving delirium are poorly understood but it has been suggested that blood cytokines and chemokines cross the blood brain barrier during delirium, directly impairing brain function. It is not known whether these molecules reach higher brain levels when the blood cerebrospinal fluid barrier (BCSFB) is impaired.

Elafibranor: A promising therapeutic approach for liver fibrosis and gut barrier dysfunction in alcohol-associated liver disease.

This article discusses the recent study written by Koizumi . Alcohol-associated liver disease (ALD) is a major cause of liver-related morbidity and mortality, which is driven by complex mechanisms, including lipid accumulation, apoptosis, and inflammatory responses exacerbated by gut barrier dysfunction. The study explored the therapeutic potential of elafibranor, a dual peroxisome proliferator-activated receptor alpha/delta agonist.

Microcystin shapes the phycosphere through community filtering and by influencing cross-feeding interactions.

The cyanobacterium causes harmful algal blooms that pose a major threat to human health and ecosystem services, particularly due to the prevalence of the potent hepatotoxin microcystin (MC). With their pronounced EPS layer, colonies also serve as a hub for heterotrophic phycosphere bacteria. Here, we tested the hypothesis that the genotypic plasticity in its ability to produce MC influences the composition and assembly of the phycosphere microbiome.

Investigating resistance to 5-Azacytidine and Venetoclax in PDX models of MDS/AML.

Introduction: Progressing myelodysplastic syndrome (MDS) into acute myeloid leukemia (AML) is an indication for hypomethylating therapy (HMA, 5-Azacytidine (AZA)) and a BCL2 inhibitor (Venetoclax, VEN) for intensive chemotherapy ineligible patients. Mouse models that engraft primary AML samples may further advance VEN + AZA resistance research.

Methods: We generated a set of transplantable murine PDX models from MDS/AML patients who developed resistance to VEN + AZA and compared the differences in hematopoiesis of the PDX models with primary bone marrow samples at the genetic level.

Impact of cell plasticity on prostate tumor heterogeneity and therapeutic response.

Epithelial-mesenchymal transition (EMT) is a dynamic process of lineage plasticity in which epithelial cancer cells acquire mesenchymal traits, enabling them to metastasize to distant organs. This review explores the current understanding of how lineage plasticity and phenotypic reprogramming drive prostate cancer progression to lethal stages, contribute to therapeutic resistance, and highlight strategies to overcome the EMT phenotype within the prostate tumor microenvironment (TME). Emerging evidence reveals that prostate tumor cells can undergo lineage switching, adopting alternative growth pathways in response to anti-androgen therapies and taxane-based chemotherapy.

Biochemical characterization of collagen I in Warmblood Fragile Foal Syndrome horse lysyl hydroxylase 1 mutation.

Mutations in the collagen-modifying enzyme lysyl hydroxylase 1 (LH1) cause Warmblood Fragile Foal Syndrome (WFFS) in horses. We investigated the impact of this mutation on collagen structure and function. Our results show that LH1 deficiency leads to reduced lysine hydroxylation, altered collagen fibril organization, and tissue abnormalities resembling human Ehlers-Danlos syndrome.

A case of testicular leiomyoma in androgen insensitivity syndrome: exploring malignancy controversies.

Testicular leiomyoma is an exceptionally rare finding in patients with androgen insensitivity syndrome (AIS). Here, we present a report of a 30-year-old individual diagnosed with complete AIS who presented with an inguinal mass subsequently identified as a right sided testicular leiomyoma. While leiomyoma are generally considered benign, controversies persist regarding the potential for malignancy in inguinal masses among AIS patients.

Methods: Case-control study. Patients with OPMD [oral leukoplakia (OL) and oral lichen planus (OLP)] and OSCC who attended two services in Spain were selected.

External validation of a novel cancer-associated venous thromboembolism risk assessment score in a safety-net hospital.

Background: Cancer-associated thrombosis (CAT) is a leading cause of death in patients diagnosed with cancer. However, pharmacologic thromboprophylaxis use in cancer patients must be carefully evaluated due to a 2-fold increased risk of experiencing a major bleeding event within this population. The electronic health record CAT (EHR-CAT) risk assessment model (RAM) was recently developed, and reports improved performance over the widely used Khorana score.

Differential pathological changes in colon microenvironments in acute and chronic mouse models of inflammatory bowel disease.

Inflammatory bowel disease is a chronic condition characterized by inflammation of the gastrointestinal tract, resulting from an abnormal immune response to normal stimuli, such as food and intestinal flora. Since the etiology of this disease remains largely unknown, murine models induced by the consumption of dextran-sodium sulfate serve as a pivotal tool for studying colon inflammation. In this study, we employed both acute and chronic colitis mouse models induced by varying durations of dextran-sodium sulfate consumption to investigate the pathological and immunologic characteristics throughout the disease course.

CMTM4 promotes the motility of colon cancer cells under radiation and is associated with an unfavorable neoadjuvant chemoradiotherapy response and patient survival in rectal cancer.
