Detection and genomic characterization of cryptosporidium parvum virus 1 (CSpV1): A potential biomarker for Cryptosporidium parvum detection in bovine calves.

Cryptosporidium parvum is a ubiquitous enteric parasite that infects a diverse range of vertebrate species. The detection of C. parvum can be confounded when oocysts are intermittently shed below an assay's limit of detection, yielding a false-negative result. We therefore investigated the utility of Cryptosporidium parvum virus 1 (CSpV1), a putative symbiont of Cryptosporidium parvum, as a surrogate target for detecting the parasite in bovine calves. Using real-time polymerase chain reaction (qPCR), we tested 422 samples for Cryptosporidium spp., C. parvum-associated targets, and CSpV1. Among…

Extrapulmonary Paragonimiasis Diagnosed by Molecular Tools.

Paragonimiasis is a parasitic disease that involves the lungs but can manifest in extrapulmonary sites, including the peritoneum or subcutaneous tissue. Diagnosis is limited by nonspecific clinical manifestations and overlapping features with other diseases, such as tuberculosis (TB). A 55-year-old Korean male presented with acute abdominal pain and a recurrent subcutaneous mass in the left thigh.

ROCK Inhibition Accelerates Mesenchymal-to-Epithelial Transition and Improves Early Survival During Human Fibroblast Reprogramming.

The low efficiency in the production of induced pluripotent stem cell (iPSC) remains a major barrier to the widespread reprogramming applications in regenerative medicine and drug screening. Small molecules that modulate key signaling pathways offer a promising approach to overcome the reprogramming limitation. Here, we demonstrated that Thiazovivin (TZV), a selective Rho-associated coiled-coil kinase inhibitor, significantly increased human fibroblast reprogramming rate by approximately 1.4-fold (*p < 0.01). Treatment with TZV during the early phase of reprogramming enhanced colony formation,

Histone Deacetylase 2 Stabilizes SPARC-related Modular Calcium Binding 2 to Promote Metastasis and Stemness in Gallbladder Cancer.

METHODS: The expression of HDAC2 and SMOC2 in GBC and normal cells was detected by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR), which was also used to detect the mRNA stability of SMOC2. The combination between HDAC2 and SMOC2 was detected by Chromatin immunoprecipitation (ChIP) assay. After silencing and/or overexpressing HDAC2 and SMOC2, cell viability, migration,

TGF-β inhibition restores hematopoiesis and immune balance via bone marrow EPCs in aplastic anemia.

Aplastic anemia (AA) is a life-threatening bone marrow (BM) failure syndrome characterized by pancytopenia. Recent studies revealed that dysfunctional endothelial progenitor cells (EPCs), critical components of the BM microenvironment, are involved in hematopoietic-dysfunction-related diseases, including AA. However, the mechanism underlying EPC damage in AA remains unknown. Here we find that transforming growth factor-β (TGF-β) signaling is hyperactive in dysfunctional AA EPCs with impaired hematopoietic support and immune regulatory ability, and TGF-β inhibition promotes hematopoiesis and im
