Two strains of a novel ascomycetous yeast species were isolated from rotting wood samples collected in Jiuxi Mountain Forest Park in Yunnan Province, southwest China. Both strains formed one or two spherical ascospores in persistent asci. Phylogenetic analysis of the concatenated sequences of the internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2) and the D1/D2 domain of the large subunit rRNA gene revealed that the novel strains represented a phylogenetically distinct species belonging to the genus . This novel species differed from the type strains of the closest known species, and , by 0.9 and 1.2 % nucleotide substitutions in the D1/D2 domain and 5.3 and 6 % nucleotide substitutions in the ITS region, respectively. The novel species can also be distinguished from and in terms of the ability to assimilate ribitol, succinate and citrate, and its ability to grow at 37 °C. The species name of sp. nov. is proposed with holotype CBS 16004 (Mycobank MB 844535).

Dough fermentation is an effective method for selenium conversion. This study investigated the effects of low NaSeO concentrations on the morphology, texture, fermentation properties, Se species, Se bioaccessibility, and antioxidant capacity of two types of yeast-leaved steamed bread. The results indicated that NaSeO did not significantly affect the specific volume; but it did result in increased hardness.

Early childhood caries (ECC), a severe form of dental caries, is exacerbated by the synergistic interaction between Streptococcus mutans and Candida albicans, leading to greater disease severity than their individual effects. This underscores the need for more targeted and potent therapeutic alternatives. Given the promising anti-infective properties of quaternary ammonium surfactants (QAS), this study explores the microbicidal properties of one such QAS, cetyltrimethylammonium chloride (CTAC), against both individual- and dual-species cultures of S.

Model organisms are commonly used to study human diseases; we set out to understand the relevance of several model organisms with relation to the σ1R protein. The study explored the interactions of σ1R with various agonists, antagonists across different species. Ligand and protein-protein (σ1R-BiP) docking approaches were used to understand the significance of σ1R in modulating neuroprotective mechanisms and its potential role in Alzheimer's.

Objective: To evaluate the characteristics of antifungal immunity in patients with bilateral chronic rhinosinusitis with nasal polyps.
Material And Methods: The study included 74 patients with bilateral chronic rhinosinusitis with nasal polyps and a control group consisting of 30 almost healthy individuals. All patients underwent surgery and were divided into two groups: Group I - with liquid secretion (=39), Group II - with thick secretion in the paranasal sinuses (=35).

Yeast two-hybrid library screening enables the discovery of novel protein-protein interactions. Identifying cytosolic host proteins targeted by host-translocated Phytophthora effector proteins relies on the mRNA amount, quality, and composition used to prepare the yeast two-hybrid cDNA library. Here we describe the steps required for the preparation of a Pinus radiata cDNA library optimized for Phytophthora effector target screening in yeast.
