Medical Students' Diagnostic Accuracy and Treatment Plans.

Physician-mentored patient rounds (PMPR) were used to assess diagnostic accuracy and treatment plans of preclinical medical students. During 4 PMPR sessions, students gathered patient history, observed a physical exam, analyzed diagnostic tests, and developed treatment plans for a patient with chronic obstructive pulmonary disease. Of 470 students, 99.

Status of Entrustable Professional Activities (EPA) Implementation at Colleges of Osteopathic Medicine in the United States and Future Considerations.

Context: Competency-based medical education, developmental milestones for residency training, and the single graduate medical education (GME) accreditation system have emerged over the last decade, necessitating new ways to adequately prepare graduates to meet new standards in proficiency, including the 13 Core Entrustable Professional Activities (EPA) for Entering Residency. The American Association of Colleges of Osteopathic Medicine (AACOM) Entrustable Professional Activities (EPA) steering committee has implemented an information-gathering process to provide suggestions for supporting a variety of EPA-related implementation efforts at colleges of osteopathic medicine (COMs) across the country.

Objective: To review the status of EPA implementation at COMs nationally.

Physician-Mentored Patient Rounds to Observe and Assess Entrustable Professional Activities 1 and 2 in Preclinical Medical Students.

Context: Thirteen entrustable professional activities (EPAs) for entering residency were created to aid medical educators as they prepare preclinical students for their residency and to assess student readiness for residency. The A.T.

Entrustable Professional Activities for Entering Residency: Establishing Common Osteopathic Performance Standards in the Transition From Medical School to Residency.

Entrustable professional activities (EPAs) are measurable units of observable professional practice that can be entrusted to an unsupervised trainee. They were first introduced as a method of operationalizing competency-based medical education in graduate medical education. The American Association of Medical Colleges subsequently used EPAs to establish the core skills that medical students must be able to perform before they enter residency training.

Status of caveolin-1 in various membrane domains of the bovine lens.

Recent studies of the distribution and relative concentration of caveolin-1 in fractions of bovine lens epithelial and fiber cells have led to the novel concept that caveolin-1 may largely exist as a peripheral membrane protein in some cells. Caveolin-1 is typically viewed as a scaffolding protein for caveolae in plasma membrane. In this study, membrane from cultured bovine lens epithelial cells and bovine lens fiber cells were divided into urea soluble and insoluble fractions.

Comparison of effects of U18666A and enantiomeric U18666A on sterol synthesis and induction of apoptosis.

Treatment of animals or cells with the amphipathic tertiary amine U18666A {3beta-[2-(diethylamino) ethoxy]androst-5-en-17-one} provides models for several human diseases (e.g., cataracts, Niemann-Pick disease, and epilepsy).

Distribution of caveolin-1 in bovine lens and redistribution in cultured bovine lens epithelial cells upon confluence.

The distribution of caveolin-1 in the lens and lens epithelial cells was determined to assess possible roles in cholesterol trafficking, cell to cell communication and signal transduction. Bovine lenses and cultured bovine lens epithelial cells (BLEC) were divided into subcellular fractions and the distribution of proteins recognized by three different caveolin-1 antibodies determined. The immunolocalization of caveolin-1 in the lens epithelium and in subconfluent and confluent cultured BLEC was probed by fluorescence microscopy and laser scanning confocal microscopy.

Discordant expression of the sterol pathway in lens underlies simvastatin-induced cataracts in Chbb: Thom rats.

Simvastatin rapidly induced cataracts in young Chbb:Thom (CT) but not Sprague Dawley (SD) or Hilltop Wistar (HW) rats. Oral treatment for 14 but not 7 days committed CT rat lenses to cataract formation. The cholesterol to phospholipid molar ratio in lenses of treated CT rats was unchanged.

Immunomagnetic capture of lens membrane fractions containing steroid binding protein.

This study describes the use of magnetic Dynabeads to purify microsomes from a crude microsomal fraction. A 28 kDa membrane-associated protein is proposed to mediate the binding of progesterone and other steroid hormones to ocular lens membranes and the rapid-nongenomic actions of these steroids. The subcellular location of this membrane steroid binding protein (MSBP) was probed by capture of organelles containing MSBP by magnetic beads displaying an antibody to a cytoplasmic domain of the protein.
