Super-Fine Attributes with Crowd Prototyping.

Recognising human attributes from surveillance footage is widely studied for attribute-based re-identification. However, most works assume coarse, expertly-defined categories, ineffective in describing challenging images. Such brittle representations are limited in descriminitive power and hamper the efficacy of learnt estimators.

Regional Variations in Shear Strength and Density of the Human Thoracic Vertebral Endplate and Trabecular Bone.

Background: Previous studies investigated the overall mechanical strength of the vertebral body; however, limited information is available on the biomechanical properties of different regions within the vertebral endplate and cancellous bone. In addition, the correlation between mechanical strength and various density measurements has not been studied yet.

Methods: Thoracic (T10) vertebrae were harvested from fifteen human cadaveric spines (average age: 77 years old).

A randomized controlled pilot trial comparing the impact of access to clinical endocrinology video demonstrations with access to usual revision resources on medical student performance of clinical endocrinology skills.

Background: Demonstrating competence in clinical skills is key to course completion for medical students. Methods of providing clinical instruction that foster immediate learning and potentially serve as longer-term repositories for on-demand revision, such as online videos demonstrating competent performance of clinical skills, are increasingly being used. However, their impact on learning has been little studied.

The role of insulin glulisine to improve glycemic control in children with diabetes mellitus.

Glulisine (Apidra(®)) is a rapid-acting human insulin analog approved for use in children with diabetes mellitus ≥4 years of age. Management of children with type 1 diabetes has seen a shift in favor of mimicking normal physiological insulin responses with multiple daily injections or continuous subcutaneous insulin infusions (CSII). Few studies have compared the rapid-acting insulin analogs in this population but limited data indicate that glulisine is as effective as lispro when used in a basal-bolus regimen.

Self-calibrating view-invariant gait biometrics.

We present a new method for viewpoint independent gait biometrics. The system relies on a single camera, does not require camera calibration, and works with a wide range of camera views. This is achieved by a formulation where the gait is self-calibrating.

Cellular response of human cardiac fibroblasts to mechanically simulated aortic regurgitation.

Myocardial fibrosis has been identified in biopsy specimens from catheterization and valve replacement surgery in patients with severe chronic aortic regurgitation (AR). While characterization of these extracellular matrix (ECM) alterations has been incomplete in humans, fibrosis also has been identified in chronic severe experimentally created AR, in which ECM composition features abnormal fibronectin/glycoprotein production, with normal collagen content. Virtually identical ECM variations have been induced when normal rabbit cardiac fibroblasts (CF) are subjected in culture to cyclic mechanical strain mimicking that found in the left ventricle (LV) in severe AR.

Myocardial fibrosis in chronic aortic regurgitation: molecular and cellular responses to volume overload.

Background: Myocardial fibrosis is common in patients with chronic aortic regurgitation (AR). Experimentally, fibrosis with disproportionate noncollagen extracellular matrix (ECM) elements precedes and contributes to heart failure in AR.

Methods And Results: We assessed [3H]-glucosamine and [3H]-proline incorporation in ECM, variations in cardiac fibroblast (CF) gene expression, and synthesis of specific ECM proteins in CF cultured from rabbits with surgically induced chronic AR versus controls.
