Astrocytes are glial cells of the central nervous system that modulate neuronal function. Here, we present glyoxal-fixed astrocyte nuclei transcriptomics (GFAT), a protocol for the purification and transcriptomic analysis of astrocyte nuclei from the cortex and cerebellum of adult and aged fresh mouse brain. We describe steps for tissue dissection, glyoxal fixation, homogenization, nuclei isolation, antibody staining, fluorescence-activated cell sorting, and RT-qPCR or bulk RNA sequencing. GFAT does not require transgenic lines or viral injection and allows parallel astrocyte and neuron profiling.

The plastid-encoded RNA polymerase (PEP) plays an essential role in the transcription of the chloroplast genome. Here, we present a strategy to purify the transcriptionally active protein complex from transplastomic tobacco (Nicotiana tabacum) lines in which one of the PEP core subunits is fused to an epitope tag. We describe experimental procedures for designing transformation constructs for PEP purification, selection, and analysis of transplastomic tobacco plants.

Ikarugamycin is a member of the natural product family of the polycyclic tetramate macrolactams (PoTeMs). The compound exhibits a diverse range of biological activities, including antimicrobial, antiprotozoal, anti-leukemic, and anti-inflammatory properties. In addition, it interferes with several crucial cellular functions, such as oxidized low-density lipoprotein uptake in macrophages, Nef-induced CD4 cell surface downregulation, and mechanisms of endocytosis.

Chromogenic bacterial staining of teeth: a scoping review.

BMC Oral Health

January 2025

Basic Medical and Dental Sciences Department, College of Dentistry, Ajman University, Ajman, UAE.

Article Synopsis
  • This scoping review aims to investigate the causes, clinical traits, and treatment methods for chromogenic staining of teeth, following the PRISMA 2022 guidelines.
  • A systematic search across multiple medical databases led to the identification of 989 articles, with 21 ultimately included for analysis, highlighting that chromogenic bacteria can cause staining in 3.1 to 18.5% of cases, primarily resulting in black discoloration.
  • The findings indicate a lack of comprehensive literature on this topic, emphasizing the need for further research into effective management strategies for these challenging stains linked to specific oral bacteria.
