Detecting the footprint of selection on the genome of Girgentana goat, a popular ancient breed.

Girgentana goats are an ancient breed with distinctive morphological, adaptive, and production traits, making this population an interesting model for studying the genetic architecture underlying these traits. These special features result from natural and human-mediated selection. In this study, we aimed to detect potential signatures of selection in the Girgentana genome by combining the following statistical methods: the integrated haplotype score (iHS), the standardised log-ratio of the integrated site-specific extended haplotype homozygosity test between pairs of populations (Rsb), the runs of homozygosity (ROH) islands and the population differentiation index (F).

Zoonotic Bacteria and Vector-Borne Protozoa in Troglophilus Bat Colonies in Sicily (Southern Italy): A Biomolecular Survey.

Bats, as members of the order Chiroptera, are vital to ecosystems and serve as reservoirs for numerous microorganisms, some of which can cause zoonotic diseases. Human interactions with bats are increasing due to habitat alterations, making it essential to understand their microbiota, particularly potential pathogens. This study aimed to evaluate the excretion of zoonotic bacteria and protozoa in insectivorous bats from four caves in the provinces of Ragusa, Catania, and Syracuse (Sicily, Southern Italy) using molecular biology tests for zoonotic agents, including , , , , , , , and Piroplasmids.

Clinical Reasoning: A 65-Year-Old Woman With Isolated Macroglossia as the Initial Presentation of a Rare Disease.

Macroglossia can be seen in multiple conditions, but its evaluation becomes more challenging when approached as an isolated presenting symptom. This is a case of a 65-year-old patient with isolated progressive tongue hypertrophy of unclear etiology for 5 years. We navigate the causes of macroglossia and discuss the clinical and diagnostic procedures that helped us narrow the differential diagnoses for our patient.

Protein lipidation in cancer: mechanisms, dysregulation and emerging drug targets.

Protein lipidation describes a diverse class of post-translational modifications (PTMs) that is regulated by over 40 enzymes, targeting more than 1,000 substrates at over 3,000 sites. Lipidated proteins include more than 150 oncoproteins, including mediators of cancer initiation, progression and immunity, receptor kinases, transcription factors, G protein-coupled receptors and extracellular signalling proteins. Lipidation regulates the physical interactions of its protein substrates with cell membranes, regulating protein signalling and trafficking, and has a key role in metabolism and immunity.
