In this study, a total of 30 yeast strains belonging to the genera Dipodascus, Galactomyces, Geotrichum, Magnusiomyces and Saprochaete were investigated for volatile organic compound production using HS-SPME-GC/MS analysis. The resulting flavour profiles, including 36 esters and 6 alcohols compounds, were statistically evaluated by cluster and PCA analysis. Two main groups of strains were extracted from this analysis, namely a group with a low ability to produce flavour and a group producing mainly alcohols. Two other minor groups of strains including Saprochaete suaveolens, Geotrichum marinum and Saprochaete gigas were diverging significantly from the main groups precisely because they showed a good ability to produce a large diversity of esters. In particular, we found that the Saprochaete genus (and their closed relatives) was characterized by a high production of unsaturated esters arising from partial catabolism of branched chain amino-acids. These esters were produced by eight phylogenetically related strains of Saprochaete genus.

Objectives: Despite the advances in medicine, aortic dissection remains a cardiac surgery emergency with high mortality and morbidity rates. This study examined the effects of the Glue + Felt technique, which uses biological glue and felt to repair the proximal anastomotic site, on the outcomes of patients with acute type A aortic dissection.
Methods: A total of 108 patients who underwent surgery for acute type A aortic dissection at our clinic between 2007 and 2020 were included in the study.

Background: Vaccines have contributed to the disappearance of various diseases, and almost eradicated others across the world. Studies have shown that in Lebanon a profoundly small percentage of Syrian refugee children were fully immunized by routine vaccination services. Exploring the knowledge, attitudes, and practices of parents towards vaccination is of crucial importance, given the role of parents in children's immunization.

An increasing number of treatment guidelines recommend rapid initiation of antiretroviral therapy (ART) after the diagnosis of human immunodeficiency virus (HIV) infection. However, data on the association between rapid ART initiation and alterations in brain structure and function remain limited in people with HIV (PWH). A cross-sectional analysis was conducted on HIV-positive men who have sex with men (MSM) undergoing ART.

Background: Surveys based on capillary blood show that anaemia is rampant in India, but capillary blood haemoglobin (Hb) may not accurately reflect venous blood Hb concentrations. Further, iron deficiency (ID) is thought to be the main cause of anaemia, there are no venous blood-based surveys to confirm this.
Methods: A community-based (urban, slum and rural) cross-sectional, venous blood survey was conducted in eight Indian states to estimate anaemia and ID prevalences from Hb and inflammation-corrected plasma ferritin concentrations in adolescents, adults, and elderly.

While the effect of time-of-day (morning versus evening) on hormones, lipids and lipolysis has been studied in relation to meals and exercise, there are no studies that have investigated the effects of time-of-day on ice bath induced hormone and lipidome responses. In this crossover-designed study, a group of six women and six men, 26 ± 5 years old, 176 ± 7 cm tall, weighing 75 ± 10 kg, and a BMI of 23 ± 2 kg/mhad an ice bath (8-12 °C for 5 min) both in the morning and evening on separate days. Absence from intense physical exercise, nutrient intake and meal order was standardized in the 24 h prior the ice baths to account for confounders such as diet or exercise.
