BACKGROUND A recent update suggested that the National Institute for Health and Clinical Excellence (NICE) guidance on head injury had led to safe early discharge, evidence of a reduction in the numbers of admitted patients and cost savings in some centres. The aim of this study was to use national Hospital Episodes Statistics (HES) data to determine whether admissions with head injury have cha...

OBJECTIVES/HYPOTHESIS The importance of reporting and grading surgical complications is central to quality improvement in head and neck surgery. The purpose of this study is to assess the interobserver reliability, content validity, and construct validity of the Clavien-Dindo classification system for use in grading complications related to head and neck surgery. STUDY DESIGN 1 and 2. METHO...

In this study, the force-length characteristics of the in vivo medial (GM) and lateral (GL) heads of the human gastrocnemius muscle were estimated from measurements in eight healthy male subjects. This involved: 1) dynamometry-based measurements of the moment generated during maximal isometric plantar flexion; 2) ultrasound-based measurements of fascicular length and pennation angle; and 3) ult...

Information in a computer is quantified by the number of bits that can be stored and recovered. An important question about the brain is how much information can be stored at a synapse through synaptic plasticity, which depends on the history of probabilistic synaptic activity. The strong correlation between size and efficacy of a synapse allowed us to estimate the variability of synaptic plast...

A pull-term female foetus (figure 1, plate VIII), the vertical length of trunk and head 15.2 cm.; anal, vaginal and urethric openings present on the external surface; no groove of neck seen from front or from behind, the skin passing straight down from the chin to the thorax, and from the back of the head to the back of the trunk. On the posterior aspect the hair of the head extended down to a ...

Tail morphology in primates is important for interpreting functional adaptation and phylogeny. Tail length is probably the most remarkable trait. Establishing usable methods to predict the tail length of extinct primates is a part of the basis to reconstruct primate evolution, particularly of hominoids. Previous studies revealed that sacral morphology often predicts tail length. However, most o...

The purpose of this research was to investigate the role of motor and visual experience during the development of locomotion in chicks. We have previously demonstrated that when locomotor activity is restricted immediately posthatching, chicks walk with shorter stride lengths and attenuated head bobbing movements. Head bobbing is an optokinetic response in birds, driven by the movement of the v...

The western lowland gorilla (Gorilla gorilla gorilla) is one of the most sexually dimorphic primate species. Mature males are twice the size of females and have grey fur on their backs and a fibrous, adipose crest on their heads. Such traits are likely to have evolved by sexual selection, either because they confer advantages during male-male fights or because females prefer males with more dim...

INTRODUCTION Lutzomyia intermedia s. s. and L. neivai, usually considered as belonging to just one species, constitute a complex of species. The measurements of several anatomical structures of specimens of both groups, from Brazil, Paraguay, Argentina and Bolivia were analysed. METHOD Thirty-nine structures were measured in specimens of both sexes, using a graduated ocular, analysing compari...
