Important information on cellular physiology can be obtained by directly observing living cells. The nucleus, and the chromatin within, is of particular interest to many researchers. Monitoring the behavior of specific DNA loci in the living cell is now commonly achieved through the insertion of binding sites for fluorescently tagged proteins at the sequence of interest (e.g. Ref 1). However, visualizing the behavior of full length chromosomes can only be achieved when they constitute discrete, relatively well individualized units. During meiotic mid-prophase, chromosomes of budding yeast are well-organized structures that present such characteristics, making them remarkably suited for visualization. Here we describe the optimized protocols and techniques that allow monitoring of chromosome behavior during meiotic prophase in budding yeast.

Cold atmospheric plasma (CAP) has emerged as a promising technology for neutralizing microbes, including multidrug-resistant strains. This study investigates CAP's potential as an alternative to traditional antimicrobial drugs for microbial inactivation. In the era of increasing antimicrobial resistance, there is a persistent need for alternative antimicrobial strategies.

First identified in Japan in 2009, C auris has since spread globally, leading to numerous outbreaks. Its unique virulence factors, such as biofilm formation and immune evasion, contribute to its resilience and resistance to eradication.

Achieving targeted hypermutation of specific genomic sequences without affecting other regions remains a key challenge in continuous evolution. To address this, we evolved a T7 RNA polymerase (RNAP) mutant that synthesizes single-stranded DNA (ssDNA) instead of RNA in vivo, while still exclusively recognizing the T7 promoter. By increasing the error rate of the T7 RNAP mutant, it generates mutated ssDNA that recombines with homologous sequences in the genome, leading to targeted genomic hypermutation.

Increased virulence and drug resistance in species of resulted in reduced disease control and further demand the development of potent antifungal drugs. The repurposing of non-antifungal drugs and combination therapy has become an attractive alternative to counter the emerging drug resistance and toxicity of existing antifungal drugs against and non-albicans species. This study aimed to accelerate antifungal drug development process by drug repurposing approach.

is a prevalent fungal pathogen responsible for infections in humans. As described recently, nanometer-sized extracellular vesicles (EVs) produced by play a crucial role in the pathogenesis of infection by facilitating host inflammatory responses and intercellular communication. This study investigates the functional properties of EVs released by biofilms formed by two strains-3147 (ATCC 10231) and SC5314-in eliciting host responses.
