Background: Ultrasonography can be used anywhere and allows rapid, noninvasive differentiation of soft tissue structures of the musculoskeletal system. The objectives of this study were to describe the ultrasonographic appearance of the structures of the metacarpo-/metatarsophalangeal and the interphalangeal joints, the appearance of the growth plates of the distal metacarpus/metatarsus and of the proximal phalanx and to measure the cross-sectional dimensions of the DDFT and SDFT in Nellore and Girolando calves eight to 12 months of age.
Results: In the longitudinal dorsal view the common digital extensor tendon and the digital extensor tendon were depicted as echogenic parallel fiber bundles located directly under the skin.
Purpose: Previous studies on team-based learning (TBL) in medical education demonstrated improved learner engagement, learner satisfaction, and academic performance; however, a paucity of information exists on modifications of the incentive structure of "traditional" TBL practices. The current study investigates the impact of modification to conventional Group Application exercises by examining student preference and student perceptions of TBL outcomes when Group Application exercises are excluded from TBL grades.
Methods: During the 2009-2010 and 2010-2011 academic years, 175 students (95.
BRAF V600E is the most common mutation in cutaneous melanomas, and has been described in 30-72% of such cases. This mutation results in the substitution of valine for glutamic acid at position 600 of the BRAF protein, which consequently becomes constitutively activated. The present study investigated the BRAF V600E mutation frequency and its clinical implications in a group of 77 primary cutaneous melanoma patients treated in a cancer reference center in Brazil.

The researchers hypothesized that students who perceived their career as a calling would be more committed to their speciality, especially when students had high SE. Medical students (Years 1-4; N = 152) completed an online survey to rate their calling, speciality commitment, and SE.

A culture-dependent approach was used to investigate natural associations of this crop with potentially beneficial bacteria, aiming to identify strains suitable for biofertilization purposes. Annual ryegrass seedlings were used to trap bacteria from three different soils in laboratory conditions.

Background: In the past, overtreatment may have resulted in growth impairment in patients with phenylketonuria.
Objective: The paper aims to investigate height and body composition in early treated patients with phenylketonuria who were diagnosed between 1981 and 2008.
Design: A cross-sectional study of 89 patients with phenylketonuria and 78 controls aged (mean ± SD, in years) 14.
Introduction: Patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) often have associated changes in craniofacial morphology and distribution of body fat, either alone or in combination.
Aim: To correlate cephalometric and anthropometric measures with OSAHS severity by using the apnea-hypopnea index (AHI).
Method: A retrospective cephalometry study of 93 patients with OSAHS was conducted from July 2010 to July 2012.
Background: The use of ultrasound in veterinary medicine is widespread as a diagnostic supplement in the clinical routine of small animals, but there are few reports in wild animals. The objective of this study was to describe the anatomy, topography and abdominal sonographic features of coatis.
Results: The urinary bladder wall measured 0.
Unlabelled: Concerns about recruiting physicians into academic careers is an international issue. A qualitative study with United States (US) women physicians revealed insights into how, when, and why physicians choose an academic career in medicine. The current study explored international women physicians' perspectives on their career choice of academic medicine and determined if different themes emerged.

The construct of calling has recently been applied to the vocation of medicine. We explored whether medical students endorse the presence of a calling or a search for a calling and how calling related to initial speciality interest. 574 first-year medical students (84 % response rate) were administered the Brief Calling Survey and indicated their speciality interest.

In Parkinson's disease, α-synuclein (α-Syn) is the major component of the intraneuronal inclusions found in the brains of patients. Current therapeutics is merely symptomatic, and there is a pressing need for developing novel therapies.

The haems in several of these cytochromes have been discriminated thermodynamically and their individual rates of reduction by small electron donors were characterized. The kinetic characterization of individual haems used the Marcus theory of electron transfer and assumed that the rates of reduction of each haem by sodium dithionite depend only on the driving force, while electrostatic interactions were neglected.

Purpose: Each year military medical students participate in a separate, military match culminating with the Joint Services Graduate Medical Education Selection Board (JSGMESB). Prior studies have explored postinterview communication that occurs during the National Resident Matching Program (NRMP), but not during the JSGMESB. We examined the frequency and nature of communication during the JSGMESB and compared it with the NRMP.

Effective statin therapy is associated with a marked reduction of cardiovascular events. However, the explanation for full benefits obtained for LDL cholesterol targets by combined lipid-lowering therapy is controversial. Our study compared the effects of two equally effective lipid-lowering strategies on markers of cholesterol synthesis and absorption.

The present study was done to evaluate the influence of weight loss on biometry (BIO), bioimpedance analysis (BIA) and ultrasonography (US) in cats, proposing equations to estimate fat (FM) and lean (LM) body mass, as compared to dual energy x-ray absorptiometry (DXA) as the referenced method. For this were used 16 gonadectomized obese cats (8 males and 8 females) in a weight loss program.

Simultaneously, this study explored attitudes toward homeless persons held by Psychiatry and Emergency Medicine residents and faculty in an attempt to uncover the "hidden curriculum" in medical education, in which values are communicated from teacher to student outside of the formal instruction.
Method: A group of 79 students on Psychiatry and 66 on Emergency Medicine clerkships were surveyed at the beginning and end of their rotation regarding their attitudes toward homeless persons by use of the Health Professionals' Attitudes Toward the Homeless Inventory (HPATHI).
