BACKGROUND Evidence-Based Medicine (EBM) is an important competency for the healthcare professional. Experimental evidence of EBM educational interventions from rigorous research studies is limited. The main objective of this study was to assess EBM learning (knowledge, attitudes and self-reported skills) in undergraduate medical students with a randomized controlled trial. METHODS The educat...

A generalization of Nahm’s equation has been recently conjectured by Basu and Harvey to be the BPS condition describing the bound state of a stack of M2branes ending on an M5-brane. In this note exact solutions are presented for the proposed BPS equation – which is from the point of view of the M2-brane world-volume dynamics – with boundary conditions appropriate for M2-branes stretching betwee...

We study a class of classical solutions of three-dimensional N = 6 superconformal Chern-Simons theory coupled with U(N)×U(N) bi-fundamental matter fields. Especially, time evolutions of fuzzy spheres are discussed for both massless and massive cases. For the massive case, there are a variety of solutions having different behaviors according to the value of the mass. In addition to the time-depe...

We study the central charges of the supersymmetry algebra of branes in backgrounds corresponding to wrapped M5-branes. In the case of M5-branes wrapping a holomorphic 2-cycle in C2, we find this allows for a supersymmetric M5-brane probe which is related to the M2-brane probe which describes the BPS spectra of the corresponding N = 2 worldvolume gauge theory. For the case of M5-branes wrapping ...

BACKGROUND AND OBJECTIVES Spinal morphine promotes adequate pain relief, but is not free from side effects. This study aimed at investigating the effects of different spinal morphine doses. METHODS Five groups of seven rats were studied, 24 h after spinal catheter insertion via cisterna magna under anesthesia with muscular ketamine and xylazine. G1 received 10 microl saline solution; groups G...

It is known that there are normal plane maps M5 with minimum degree 5 such that the minimum degree-sum w(S5) of 5-stars at 5-vertices is arbitrarily large. In 1940, Lebesgue showed that if an M5 has no 4-stars of cyclic type (5, 6, 6, 5) centered at 5-vertices, then w(S5) ≤ 68. We improve this bound of 68 to 55 and give a construction of a (5, 6, 6, 5)-free M5 with w(S5) = 48.
