DNA tensiometer reveals catch-bond detachment kinetics of kinesin-1, -2 and -3.

Bidirectional cargo transport by kinesin and dynein is essential for cell viability and defects are linked to neurodegenerative diseases. The competition between motors is described as a tug-of-war, and computational modeling suggests that the load-dependent off-rate is the strongest determinant of which motor 'wins'. Optical tweezer experiments find that the load-dependent detachment sensitivity of transport kinesins is kinesin-3 > kinesin-2 > kinesin-1.

Improving Medical Student Access to Nutrition During the Core Surgery Clerkship.

The rigorous demands of medical education create circumstances that can make it challenging to maintain a healthy diet. Evaluations from students at an urban medical school in the northeast U.S.

Feasibility and Efficacy of Sentinel Lymph Node Mapping in Gastric Cancer.

Background: Lymph node metastasis is a critical prognostic factor for patients with gastric carcinoma (GC). Sentinel lymph node (SLN) mapping has the potential to identify the initial site of draining lymph node metastasis and reduce the extent of surgical lymphadenectomy. This study aimed to evaluate the diagnostic accuracy of SLN mapping in GC.

Patient satisfaction with women vs men surgical interns and senior residents.

Background: Patient satisfaction is critical for referrals and reimbursement of surgical faculty but remains poorly characterized for residents. We investigated whether patient evaluations of surgical trainees vary by resident gender.

Methods: Surgical inpatients evaluated surgical resident care postoperatively after positively identifying trainees.

Quantification of Visceral Fat at the L5 Vertebral Body Level in Patients with Crohn's Disease Using T2-Weighted MRI.

The umbilical or L3 vertebral body level is often used for body fat quantification using computed tomography. To explore the feasibility of using clinically acquired pelvic magnetic resonance imaging (MRI) for visceral fat measurement, we examined the correlation of visceral fat parameters at the umbilical and L5 vertebral body levels. We retrospectively analyzed T2-weighted half-Fourier acquisition single-shot turbo spin echo (HASTE) MR axial images from Crohn's disease patients who underwent MRI enterography of the abdomen and pelvis over a three-year period.
