Much progress documenting the diversity and relationships within the Hydnaceae has been made over the past decades. Nevertheless, the diversity of the family is far from completely known, especially in neotropical regions, which remain underexplored. Concentrated fieldwork to document the diversity and distribution of macrofungi in Costa Rica began in the late 1980s and continued through early 2000s. As most of the studies were morphology based, some species were identified only to genus level, provisionally named, or misidentified. This study provides morphological and molecular evidence of new species of Hydnaceae previously and newly collected in neotropical -dominated forests in Costa Rica. Molecular phylogenies support the proposal of five new species: a yellow chanterelle , three species: , sp. nov. , sp. nov. and , sp. nov. and a lookalike: , sp. nov.

Coffee plants and beans are prone to fungal contamination that pose health risks to consumers by producing mycotoxins like ochratoxin A (OTA). Thus, the present study aimed to analyze the mycobiota of Costa Rican coffee beans, focusing on potentially ochratoxigenic species and their in vitro susceptibility patterns to antifungal agents. Fungal isolates were obtained from cherry, green, and roasted coffee beans from Costa Rica; they were identified by morphology, MALDI-TOF technology, and sequencing.

Human proteinase 3 (hPR3) is a lysosomal enzyme of the serine protease type. In autoimmune vasculitis, autoantibodies to hPR3 appear to have a role in the inception of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), where this protein is the main autoantigen. Indeed, patients with antibodies against hPR3 have more severe symptoms, relapses, and resistance to immunosuppressive therapies, supporting an important role for this autoantigen in the pathophysiology and severity of AAV.

SLICK1 is an allelic variant of the prolactin receptor () that is found in Senepol beef cattle. The presence of a single copy of this allele produces a short hair coat and confers heat tolerance. We aimed to determine the effect of 2 copies of this allele on milking performance of dairy cattle.

Autism spectrum disorder (ASD) is a neurodevelopmental syndrome that impacts two main areas: social communication and restrictive or repetitive behaviors. Other symptoms and comorbidities may be manifested, according to the different clinical presentations and severity levels. ASD diagnosis can be performed by two years of age; however, certain diagnostic challenges may lead to a late diagnosis and significant intervention delay.

Struma ovarii (SO) is a rare form of ovarian teratoma predominantly composed of thyroid tissue. While most cases follow a benign course, some may exhibit malignant transformation or extra-ovarian spread. We present the case of a 43-year-old woman with a history of SO previously treated with right oophorectomy and systemic chemotherapy, along with a separate diagnosis of papillary thyroid carcinoma managed with total thyroidectomy and radioactive iodine ablation.
