Optimization of cerebrospinal fluid microbial DNA metagenomic sequencing diagnostics
We implemented a metagenomic DNA sequencing methodology to unbiasedly detect microbial species in CSF samples from patients with CNS symptoms in which a pathogen or EBV had been detected (Additional 3: Table 1). Samples positively identified with pathogen-specific quantitative PCR (qPCR), 16S rRNA gene sequencing or bacterial/mycotic culture in CSF…
Drosophila carrying epilepsy-associated variants in the vitamin B6 metabolism gene PNPO display allele- and diet-dependent phenotypes
Pyridox(am)ine 5′-phosphate oxidase (PNPO; Enzyme Commission Number 1.4.3.5) is a rate-limiting enzyme in the synthesis of vitamin B6 (VB6) (1). Mutations in PNPO can cause neonatal epileptic encephalopathy, a devastating disease that usually leads to death if untreated (2). Recently, PNPO mutations have also been reported in patients with infantile…
LAMP-CRISPR-Cas12a-lateral flow immunochromatographic strip | IDR
Introduction About 700,000 people die from “superbugs” globally every year. Antibiotic abuse is the culprit of extensive spread of superbugs. Currently, carbapenemase-producing organisms are among the most important pathogens of hospital infections. Especially the plasmid-mediated highly transmissible carbapenem-resistant Enterobacterales (CRE) has become an important public health issue of global concern….

Exosomal microRNA-618 derived from mesenchymal stem cells attenuate the progression of hepatic fibrosis by targeting Smad4
Introduction Hepatic fibrosis (HF) is a pathological phenomenon produced in the process of long-term damage and repair in the liver [1,2]. During the formation of HF, hepatocytes are damaged by various factors, such as chronic liver disease, and excessive intake of alcohol, and secrete a variety of cytokines [3]. Subsequently,…
CD Genomics Perspective: Bioinformatic Analysis for Microbial Metagenomics
Introduction to Bioinformatics for Microbial Metagenomics In microbial ecology, metagenomic techniques are now widely utilized to research microbial communities in greater depth, including many strains that cannot be produced in the lab. Microbial bioinformatics may now be used to mine large metagenomic datasets for broad patterns that govern microbial communities….

Pathogenomix Developing Infectious Disease Testing Platform Enabled by Cloud-Based Analytics, NGS
NEW YORK — Pathogenomix is combining sequencer-agnostic, cloud-based analytics software with 16S rRNA gene sequencing to enable hospital laboratories to identify the pathogens behind life-threatening bacterial infections. Though no NGS-based tests have obtained full US Food and Drug Administration authorization to identify infectious disease pathogens, Pathogenomix said it is on…
Requirement of Xk and Vps13a for the P2X7-mediated phospholipid scrambling and cell lysis in mouse T cells
Significance The extracellular concentration of adenosine triphosphate (ATP) reaches several hundred micromoles in the inflamed tissues or tumor environment. A high concentration of ATP activates P2X7, a purinergic receptor, and induces the formation of a nonselective cation channel, accompanied by reversible phosphatidylserine (PtdSer) exposure, leading to cell lysis. Here, we…
Mitochondrial DNA content reduction in the most fertile spermatozoa is accompanied by increased mitochondrial DNA rearrangement
Study question: Is there an association between male fertility and spermatozoa mitochondrial DNA (mtDNA) copy number and genome rearrangements? Summary answer: Normal spermatozoa not only have a lower mtDNA copy number but also more DNA rearrangements than spermatozoa of men with severe oligoasthenospermia (SOA). What is known already: While there…

Cell Strain-Derived Induced Pluripotent Stem Cells as an Isogenic Approach To Investigate Age-Related Host Response to Flaviviral Infection
INTRODUCTION Dengue is the most common mosquito-borne viral disease globally (1). This acute disease, which can be life-threatening, is caused by four different dengue viruses (DENVs) (DENV-1, DENV-2, DENV-3, and DENV-4). An estimated 390 million people are infected with these DENVs annually (2), and populations throughout the tropics face frequent…
Genetic variants of XRCC1 and risk of hepatocellular carcinoma in chronic hepatitis C patients: British Journal of Biomedical Science: Vol 76, No 2
ABSTRACT Background: Hepatitis C virus (HCV) related liver cirrhosis occurs in about 20% of chronically infected patients over a duration of 10–20 years, and within 5 years approximately 10–20% of these cirrhotic patients will develop hepatocellular carcinoma (HCC).
