Published: August 2010

Human leucocyte antigen (HLA)-B*4509 differs from the closest HLA-B*4502 by three nucleotides that lead to changes of Tyr113His, Asn114Asp and Phe116Ser. HLA-B*5212 differs from HLA-B*520101 by a single nucleotide substitution, leading to a change of Asn114Asp.

The extent of functional sequences within the human genome is a pivotal yet debated topic in biology. Although high-throughput reverse genetic screens have made strides in exploring this, they often limit their scope to known genomic elements and may introduce non-specific effects. This underscores the urgent need for novel functional genomics tools that enable a deeper, unbiased understanding of genome functionality.

Transgender (TG) people are individuals whose gender identity and sex assigned at birth do not match. They often undergo gender-affirming hormone therapy (GAHT), a medical intervention that allows the acquisition of secondary sex characteristics more aligned with their individual gender identity, providing consistent results in the improvement of numerous socio-psychological variables. However, GAHT targets different body systems, and some side effects are recorded, although not yet fully identified and characterized.

Atherosclerosis is a major cause of morbidity and mortality worldwide; in Israel, ischemic heart disease is the second leading cause of death for both genders aged 45 and above. Atherosclerosis involves stiffening of the arteries due to the accumulation of lipids and oxidized lipids on the blood vessel walls, triggering the development of artery plaque. Coronary artery disease (CAD) is the most common manifestation of atherosclerosis.

<b>Background and Objective:</b> Peatlands are unique ecosystems rich in microbial diversity, including bacteria with potential antibiotic activity. This study focuses on the isolation and characterization of bacteria from Indonesian peat soil, particularly their potential to produce antibiotics against multidrug-resistant (MDR) pathogens, including Methicillin-Resistant <i>Staphylococcus aureus</i> (MRSA). <b>Materials and Methods:</b> Bacterial isolates were rejuvenated on nutrient agar and subjected to antimicrobial activity testing using the Bauer & Kirby diffusion method against MRSA.

Last decades led to a revolution in the management of ulcerative colitis (UC), due to the development of novel advanced therapies and the identification of increasingly ambitious therapeutic goals. Nevertheless, a subset of patients, refractory to available therapies, still requires proctocolectomy with ileal pouch-anal anastomosis (IPAA). Pouchitis, an inflammatory condition of the ileal pouch, is the most common long-term complication of IPAA, affecting almost one-half of patients in the first 10 years after surgery.
