Background: The importance of pigeons as reservoirs and carriers of Cryptococcus neoformans and other species of this genus is well-known; however, less is known about their role as reservoirs and carriers of other yeasts that impact public health.
Aims: The present study was performed on Gran Canaria Island to define yeasts other than Cryptococcus spp. that have been reported to impact public health and which could be carried by pigeons.
Methods: Samples were obtained from 83 pigeon lofts (Columba livia); moreover, 331 crop samples, 331 cloacal samples and 174 dropping samples were collected. In addition, 17 dropping samples were taken from a total of 17 public squares. Samples were inoculated on Sabouraud dextrose agar with chloramphenicol.
Results: Different yeast species, i.e. Candida guilliermondii (24.36%), Candida kefyr (1.21%), Saccharomyces cerevisiae (2.43%), and Trichosporon asahii (1.21%) were isolated for the first time from the cloaca. The most frequently isolated yeast from the crop, cloaca and dropping samples from lofts was C. guilliermondii (30.46%, 24.36% and 49.37%, respectively). In addition, for the first time, C. kefyr (3.65%), Candida pelliculosa (2.43%), Candida rugosa (1.21%), T. asahii (3.65%), Trichosporon mucoides (3.65%) and Prototheca wickerhamii (1.21%) were obtained from crop samples; Candida pelliculosa (1.20%), T. asahii (9.63%) and T. mucoides (7.22%) were isolated from dropping samples in the lofts. Candida albicans was the most frequently isolated yeast in dropping samples collected in public squares.
Conclusions: It can be assumed that pigeons and their droppings act as carriers and reservoirs of Candida spp. and other zoonotic yeasts.

Background: The topic of end-of-life decisions is important due to aging populations and the rising number of terminal illnesses like cancer. As more people experience suffering, the ethical, medical, and legal debates of these decisions become significant to healthcare policy. Understanding medical professionals' attitudes is critical for shaping responsible practices and legislation surrounding end-of-life care.

In clinical practice, there is a demand for innovative wound healing methods to tackle full thickness skin injuries, especially in those with diabetes. In this study, we examined if collagen-based hydrogel from amniotic membrane (CHAM) loaded with quercetin could enhance healing in diabetic rats. Sixty diabetic rats were randomly divided into the control group, CHAM group, quercetin group, and CHAM+Quercetin group.

Background and aim Etiopathogeneses of chronic rhinosinusitis are poorly understood. Recent research emphasizes culture-independent molecular sequencing to identify clusters of flora that may function as drivers of inflammation. Studies also indicate that macrolides are as effective as corticosteroids in controlling chronic rhinosinusitis.

This study was intended to provide a novel process that fills a knowledge gap in relation to the enhancement of pulses utilization. The primary goal was to develop an experimental framework for using a high-pressure supercritical fluid extruder (SCFX) as a continuous bioreactor to produce off-flavor reduced and functionally superior pulse flours and protein concentrates in a single step. The current study focused on using SCFX processing to remove off-flavor from pulse flour and protein concentrates, enhancing the quality, acceptability, and marketability of pulse-based products.
