BACKGROUND Smoking is the leading cause of COPD. Exploring molecular markers and understanding the pathogenic mechanisms of smoking-related COPD are helpful for early clinical diagnosis and treatment of the disease. This study aims to identify specific circulating microRNAs (miRNAs) from the blood of COPD patients with a long history of smoking. METHODS Blood samples from four different group...

Bacillus circulans xylanase contains two histidines, one of which (His 156) is solvent exposed, whereas the other (His 149) is buried within its hydrophobic core. His 149 is involved in a network of hydrogen bonds with an internal water and Ser 130, as well as a potential weak aromatic-aromatic interaction with Tyr 105. These three residues, and their network of interactions with the bound wate...

Protein prenyltransferases catalyze the covalent attachment of isoprenoid lipids (farnesyl or geranylgeranyl) to a cysteine near the C terminus of their substrates. This study explored the specificity determinants for interactions between the farnesyltransferase of Saccharomyces cerevisiae and its protein substrates. A series of substitutions at amino acid 149 of the farnesyltransferase beta-su...

Facio-Auriculo-Vertebral (FAV) spectrum, also known as Goldenhar syndrome or first and second branchial arch syndrome, is a complex of mainly craniofacial and vertebral anomalies. Microtia is a principal malformation in this complex; it can be unilateral or bilateral. We performed an observational, retrospective, transverse descriptive clinical study, reviewing 149 records of patients with a di...

Objective: We aimed to analyze the pregnancy outcomes of cases that were diagnosed prenatally with tetralogy Fallot (TOF) and investigate its prenatal diagnosis, treatment conditions, postnatal outcomes. Methods: The clinical information data a total 149 fetuses TOF (145 singleton 4 twins) collected reviewed retrospectively between January 2016 2022 at İstanbul Kanuni Sultan Süleyman Training R...
