Microbiome mediates early life immune deviation in asthma development. Recurrent wheeze (RW) in pre-school years is a risk factor for asthma diagnosis in school-age children. Dysbiosis exists in asthmatic airways, while its origin in pre-school years and relationship to RW is not clearly defined.

Article Synopsis
  • Drug resistance in Mycobacterium tuberculosis (MTB) poses significant challenges in treating tuberculosis, with existing mutations not fully explaining all cases.
  • Researchers analyzed whole genome sequencing data from 743 drug-resistant and 367 drug-sensitive MTB strains, uncovering 20 genetic markers and 83 point markers (including frameshift mutations and insertions/deletions) significantly associated with drug resistance.
  • The study's findings enhance the understanding of genetic factors contributing to drug resistance in MTB, potentially leading to new strategies for combating this public health issue.

The aim of this study is to investigate the mutation pattern of the folC gene in drug-resistant Mycobacterium tuberculosis (MTB) clinical isolates of global and Hong Kong cohorts. The public sequence read archives of 1,124 MTB genomes from three independent studies were retrieved and folC mutations existing solely in drug-resistant MTB strains were identified. A phylogenetic tree was constructed to analyze the segregation of mutation-related amino acid residues in the FolC structure.

Unlike many other human solid tumors, ovarian tumors express many epithelial markers at a high level for cell growth and local invasion. The phosphoprotein Pinin plays a key role in epithelial cell identity. We showed that clinical ovarian tumors and ovarian cancer cell lines express a high level of Pinin when compared with normal ovarian tissues and immortalized normal ovarian surface epithelial cell lines.

Background: Endometriosis is frequently associated with and thought of having propensity to develop into ovarian clear cell carcinoma (OCCC), although the molecular transformation mechanism is not completely understood.

Methods: We employed immunohistochemical (IHC) staining for marker expression along the potential progression continuum. Expression profiling of microdissected endometriotic and OCCC cells from patient-matched formalin-fixed, paraffin-embedded samples was performed to explore the carcinogenic pathways.

We report the draft genome sequence of an extensively drug-resistant strain of Acinetobacter baumannii, CUAB1, isolated from a patient in a local Hong Kong hospital. MIC testing was performed, and genes previously associated with drug resistance were located.
