A new protease named NJP with fibrinolytic activity was isolated from Neanthes japonica (Izuka), by a combination of ammonium sulfate fractionation, hydrophobic chromatography, ion-exchange chromatography and gel filtration. The molecular mass of NJP was approximately 28.6-33.5kDa as estimated by MALDI-TOF mass spectrometry and SDS-PAGE, which revealed a monomeric form of the protease. The isoelectric point of NJP determined by 2-DE was 9.2. NJP was stable in the range of pH 7.0-11.0 with a maximum enzymatic activity at 40°C and pH 9.0. The hydrolyzing activity of NJP on fibrinogen started from the Aα-chain, followed by the Bβ-chain, and the γ-chain at last. NJP had also a higher specificity for the chromogenic substrate S-2238 for thrombin. NJP activity was completely inhibited by PMSF. Analysis of partial amino acid sequences showed that NJP had very low homology with other known fibrinolytic enzymes. These results indicate that NJP is a novel alkaline thrombin-like serine protease. Thus NJP may have potential applications in the prevention and treatment of thrombosis.

Background: Established risk models may not be applicable to patients at higher cardiovascular risk with a measured Lp(a) (lipoprotein[a]) level, a causal risk factor for atherosclerotic cardiovascular disease.
Methods: This was a model development study. The data source was the Nashville Biosciences Lp(a) data set, which includes clinical data from the Vanderbilt University Health System.
Background: SGLT-2i and GLP-1RA are recommended for persons with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD); for those prescribed, little is known about reasons for discontinuation.
Methods: From the COORDINATE-Diabetes randomized trial database, the frequency and reasons for discontinuation of SGLT2i or GLP-1RA were analyzed.
Results: 1045 participants were enrolled 7/2019 to 5/2022; 290 (27.
Medical students' understanding of clinical empathy - a qualitative exploratory interview study.

Background: Empathy plays an important role in the interaction and communication with patients. Physicians' empathy has various positive patients' and physicians' outcomes. Despite the inclusion of empathy in medical curricula and the relevance of empathy in general and physicians' concept of it to medical care, there is no common definition of empathy in the clinical context: definitions tend to be abstract and we do not know enough about medical students' conceptualization of clinical empathy.
View Article and Find Full Text PDFBackground: Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), is a leading cause of morbidity and mortality, and health disparities have been shown to influence disease burden.
Aim: In this review, we aim to characterize disparities in prevalence, diagnosis, treatment, and outcomes of MASLD, and to make recommendations for next steps to minimize these disparities.
Methods: Literature search on PubMed and Scopus databases was conducted to identify relevant articles published before September 2, 2024.
All-Suture Anchor Techniques for Biceps Tenodesis Are Noninferior in End-Cycle Stiffness to an Interference Screw Technique; However, Secondary Outcomes, Such as Ultimate Failure Load, Yield Load, Creep, and Load-to-Failure Stiffness, Are Inferior in an Ovine Model.

Purpose: To assess the biomechanical performance of 2 simplified loop-and-tack biceps tenodesis techniques, all-suture anchor and all-suture anchor with a button, compared with the interference screw technique in an ovine model.
Methods: Twenty-one biceps tenodesis procedures were executed on the humeri and flexor digitorum profundus tendons of skeletally mature, female sheep. Limbs were evenly randomized into 2 experimental groups (all-suture anchor with or without button) and 1 control group (interference screw).
