Among the proposed network models, the hidden variable (or good get richer) one is particularly interesting, even if an explicit empirical test of its hypotheses has not yet been performed on a real network. Here we provide the first empirical test of this mechanism on the world trade web, the network defined by the trade relationships between world countries. We find that the power-law distrib...

A compared study of the morphology of the alimentary tract and liver of seven selected species corresponding to the main clades of the Characidae family is presented herein. Three new set of characters corresponding to 1) alimentary tract gross anatomy, 2) alimentary tract histology and 3) liver gross anatomy are evaluated as potential sources of data for future phylogenetic studies of the Char...

Current generations of graduate students have been immersed in technology from their early school years and have high expectations regarding digital resources. To better meet the expectations of Gross Anatomy students at our institution, electronic radiology teaching files for first-year coursework were organized into a web site. The web site was custom designed to provide material that directl...

INTRODUCTION This study was conducted to correlate the personal formaldehyde (FA) exposure levels of instructors and students with the indoor FA concentrations in gross anatomy laboratory at King Saud University. The personal FA levels of instructors and students are higher than the indoor FA concentration in the gross anatomy laboratory. MATERIALS AND METHODS The gross anatomy laboratory at ...

Anatomy is considered as a major subject not only in the preclinical years but also in the clinical years. Even in post graduate studies of surgical faculties, it is very helpful to revise the knowledge of gross anatomy as it provides visual positive corroboration in the learning process [1]. Dissection of cadavers is certainly the best mode of learning gross anatomy and it has played an import...

At most institutions, education in the anatomical sciences has undergone several changes over the last decade. To identify the changes that have occurred in gross anatomy, microscopic anatomy, neuroscience/neuroanatomy, and embryology courses, directors of these courses were asked to respond to a survey with questions pertaining to total course hours, hours of lecture, and hours of laboratory, ...

BACKGROUND This study was undertaken to determine whether medical students' recall of anatomy is lost when the student reaches clinical years, and whether a four month teaching of Anatomy in the pre-clinical years had any impact. METHODS A cross-sectional study, using a short answer type paper consisting of eight questions in anatomy was administered randomly to 5th, 6th and 7th year medical ...
