The open reading frame of the OprI lipoprotein gene from Pseudomonas aeruginosa was amplified by polymerase chain reaction (PCR) starting from purified DNA or colony lysates. A fragment of the expected size (249 bp) was detected in all P. aeruginosa strains from various clinical and geographical origins. The gene could only be amplified in pseudomonads of rRNA group I which are considered to be the authentic genus Pseudomonas. Digestions with HaeIII, PvuII and SphI of the amplified fragments demonstrated a sequence variation in the oprI gene. Colony, dot and Western blots with two monoclonal antibodies (mAbs) against the lipoprotein I confirmed our PCR results. These findings open interesting perspectives for the molecular taxonomy of the genus Pseudomonas and the development of diagnostic tools.

Lipid-lowering drugs have been used in clinics widely. It is unclear whether the drugs have an effect on renal failure. We chose high-density lipoprotein cholesterol (ieu-b-109), low-density lipoprotein cholesterol (ieu-a-300), triglyceride (ieu-b-111), and total cholesterol (ebi-a-GCST90038690) as exposures.

Previous studies have found that dyslipidemia is a risk factor for pancreatic cancer (PC), and that lipid-lowering drugs may reduce the risk of PC. However, it is not clear whether dyslipidemia causes PC. The Mendelian randomization (MR) study aimed to investigate the causal role of lipid traits in pancreatic cancer and to assess the potential impact of lipid-lowering drug targets on pancreatic cancer.

Tangier disease is an extremely rare autosomal recessive monogenic disorder caused by mutations in the ATP binding cassette transporter A1 gene (ABCA1). It is characterized by severe deficiency or absence of high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-1 (ApoA1), with highly variable clinical presentations depending on cholesterol accumulation in macrophages across different tissues. We report a case of a 47-year-old man with very low HDL-C and very high triglyceride levels, initially attributed to the patient's metabolic syndrome, alcohol abuse, and splenomegaly.

: Sitosterolemia is a rare autosomal recessive disorder characterized by diverse clinical manifestations ranging from asymptomatic cases to the development of xanthomas, hypercholesterolemia, premature atherosclerosis, or even sudden death during childhood. It results from homozygous or compound heterozygous pathogenic variants in the or genes. Prompt detection and intervention are essential to managing this condition and preventing severe outcomes.

Deregulation of micro-RNAs (miRNAs) may contribute to mechanisms of injury in the bicuspid aortic valve (BAV). Our objective was to investigate the expression of miRNAs in aortic tissue from patients who underwent aortic valve replacement for aortic stenosis and its relationship with aortic dilatation. The study included 78 patients, 40 with bicuspid aortic valve (BAV) and 38 with tricuspid aortic valve (TAV).
