Microsatellites are repeating sequences of 2-6base pairs of DNA. Currently, they are used as molecular markers in many organisms, specifically in genetic studies analyzing kinship and population structure. In addition, they can be used to study gene duplication and/or deletion. Although they are used in studies on microorganisms including fungi, bacteria, protists, and archaea, it appears that these genetic markers are not being utilized to their full microbiological potential. Microsatellites have many advantages over other genetic markers currently in use as they are in general species specific, and therefore, cross-contamination by nontarget organisms is rare. Furthermore, microsatellites are suitable for use with fast and cheap DNA extraction methods, with ancient DNA or DNA from hair and fecal samples used in noninvasive sampling, making them widely available as a genetic marker. Microsatellites have already proven to be a useful tool for evolutionary studies of pathogenic microorganisms such as Candida albicans and Helicobacter pylori, and the onset of new sequencing techniques (such as 454, PACBIO, and mini-ion sequencing) means the ability to detect such markers will become less time consuming and cheaper, thus further expanding their potential to answer important microbial ecology questions.

People with HIV (PWH) are living longer and experiencing a greater burden of morbidity from non-AIDS-defining conditions. Chronically treated HIV disease is associated with ongoing systemic inflammation that contributes to the development of chronic conditions (eg, cardiovascular disease) and geriatric syndromes (eg, frailty). Apart from HIV disease, a progressive increase in systemic inflammation is a characteristic feature of biologic aging, a process described as "inflammaging.

As a core genetic biomolecule in ecosystems, the metabolic processes of DNA, particularly DNA replication and damage repair, are regulated by Flap endonuclease 1 (FEN1). Abnormal expression and dysfunction of FEN1 may lead to genomic instability, which can induce a variety of chromosome-associated disorders, including tumours. FEN1 has emerged as a prominent tumour marker.

X-linked ichthyosis (XLI) is a genetic disorder characterized by a steroid sulfatase (STS) deficiency inducing excessive cholesterol sulfate accumulation and keratinization. Our study utilizes STS knockout mice to reproduce the hyperkeratinization typical of XLI, providing a valuable model for investigating the underlying mechanisms. From the experiment of STS-deficient keratinocytes using the CRISPR/Cas9 system, we observed upregulation of E-cadherin, which is associated with keratinocyte differentiation and stratification.

Organophosphate pesticides (OPPs) are widely used chemical pesticides in all the developed countries. Among the OPPs, Chlorpyrifos (CPF) is predominantly used and has been linked to various adverse health effects from acute to chronic exposure. Exposure to pesticides both occupationally and environmentally causes frequent human health problems including neurological disorders, liver, kidney dysfunctions and cancer.

Introduction: Dengue viruses (DENVs), the causative agents of dengue hemorrhagic fever and dengue shock syndrome, undergo genetic mutations that result in new strains and lead to ongoing global re-infections.
Objectives: To address the growing complexity of identifying and tracking biological samples, this study screened RNA barcode segments for the four DENV serotypes, ensuring high specificity and recall rates for DENV identification using segments.
Results: Through analyzing complete genome sequences of DENVs, we screened eight barcode segments for DENV, DENV-1, DENV-2, DENV-3, and DENV-4 identification.
