Phylogenomic delineation of two new species of ascomycetous yeasts, sp. nov. and sp. nov., and proposal of two synonyms, and .

Two novel ascomycetous yeast species of the genus are proposed based on isolates obtained in Thailand from food waste and the fruiting body of a polypore fungus, and on a combination of conventional DNA-barcode sequence analyses and whole-genome phylogenies. We focus on a particular subclade of the genus that contains species found in anthropic environments and describe sp. nov.

Taxogenomic analyses of f.a, sp. nov. and f.a., sp. nov., two novel species isolated from plant substrates and insects.

Four yeast isolates collected from flowers from different ecosystems in Brazil, one from fruit of in Argentina, three from flowers of in Chile and one obtained from the proventriculus of a female bumblebee in Canada were demonstred, by analysis of the sequences of the internal transcribed spacer (ITS) region and D1/D2 domains of the large subunit rRNA gene, to represent two novel species of the genus . These species are described here as f.a, sp.

Tracking alternative versions of the galactose gene network in the genus and their expansion after domestication.

When grows on mixtures of glucose and galactose, galactose utilization is repressed by glucose, and induction of the gene network only occurs when glucose is exhausted. Contrary to reference alleles, alternative alleles support faster growth on galactose, thus enabling distinct galactose utilization strategies maintained by balancing selection. Here, we report on new wild populations of harboring alternative versions and, for the first time, of alternative alleles.

Patients And Design: This cross-sectional study included 154 women aged 20-40 years with a diagnosis of PCOS, who were screened for prediabetes and diabetes by the OGTT and HbA1c. Women with diabetes, hyperprolactinemia, thyroid or adrenal diseases, and anemia and users of hormonal contraception or corticosteroids were excluded.

activity of the novel Fe-cyclam complex against clinical multidrug-resistant bacterial isolates from Brazil.

To evaluate the effect of a new Fe-cyclam complex on pathogenic bacterial species, including multidrug-resistant clinical specimens. The complex [Fe(cyclam)ox]PF (D2) was tested in cytotoxicity and MIC tests. Clinical and reference strains of Gram-negative and Gram-positive bacteria were used.

Do microbes evade domestication? - Evaluating potential ferality among diastatic Saccharomyces cerevisiae.

Certain lineages of the wine, beer and bread yeast Saccharomyces cerevisiae have diastatic activity. They contain the chimeric gene STA1 that codes for an extracellular glucoamylase which enables the strains to degrade starch and dextrins. Beer contaminations by diastatic yeasts can be dangerous because they can cause super-attenuation due to the consumption of otherwise non-fermentable oligosaccharides, gushing and off-flavours.

Association between sickle cell disease and periodontal disease: A systematic review.

Previous studies have evaluated the association between sickle cell disease (SCD) and periodontal disease; however, their effect on the periodontal parameters remains unclear. This systematic review aimed to investigate whether individuals with sickle cell disease (SCD) increase the risks of periodontal disease more than those without. For the selection of eligible studies, an electronic search was conducted in the MEDLINE/PubMed, Web of Science, Cochrane Library, and Scopus databases.

Interview with Sonia Guajajara: the Indigenous movement in the face of the COVID-19 pandemic.

In this interview, Sonia Guajajara, the executive coordinator of the Brazil's Indigenous Peoples Articulation (APIB), addresses the analyzis and strategies developed by the Indigenous movement to face the COVID-19 pandemic. Among other topics, she highlights some of the movement's strategies concerning communication, surveillance, and the monitoring of COVID-19, as well as its actions to support Indigenous territories, the initiatives carried out in the Legislative and Judiciary realms, the movement's international incidence, and its articulation with academia. Sonia shows the important role played by the Indigenous movement to control the health emergency and to defend the rights of the Indigenous peoples, in the framework of intense conflicts with the federal government and setbacks in public policies.

REPERCUSSIONS OF BARIATRIC SURGERY ON METABOLIC PARAMETERS: EXPERIENCE OF 15-YEAR FOLLOW-UP IN A HOSPITAL IN MACEIÓ, BRAZIL.

Objective: Obesity is a disease characterized by an excessive accumulation of body fat, which is harmful to health, and it has grown significantly in the past years in the majority of countries. The surgery should be recommended to those patients with obesity who did not succeed in conservative clinical therapy after a rigorous analysis by a multidisciplinary team. The aim of this study was to compare metabolic results, weight loss, and parameters associated with obesity in the preoperative and postoperative periods of patients treated with bariatric surgery.

Global distribution of IRC7 alleles in Saccharomyces cerevisiae populations: a genomic and phenotypic survey within the wine clade.

The adaptation to the different biotic and abiotic factors of wine fermentation has led to the accumulation of numerous genomic hallmarks in Saccharomyces cerevisiae wine strains. IRC7, a gene encoding a cysteine-S-β-lyase enzyme related volatile thiols production in wines, has two alleles: a full-length allele (IRC7 ) and a mutated one (IRC7 ), harbouring a 38 bp-deletion. Interestingly, IRC7 -encoding a less active enzyme - appears widespread amongst wine populations.
