Despite the importance that concepts of arboreal stability have in theories of primate locomotor evolution, we currently lack measures of balance performance during primate locomotion. We provide the first quantitative data on locomotor stability in…

OBJECTIVES: Platyrrhines span two orders of magnitude in body size and are characterized by diverse feeding behaviors and diets. While size plays an important role in primate feeding behavior and masticatory apparatus morphology, we know little about…

We studied the histology and morphometrics of the hairs of bowhead whales (Balaena mysticetus). These whales are hairless except for two patches of more than 300 hairs on the rostral tip of the lower lip and chin, the rostral tip of the upper lip,…

The field of evolutionary developmental biology is broadly focused on identifying the genetic and developmental mechanisms underlying morphological diversity. Connecting the genotype with the phenotype means that evo-devo research often considers a…

The need to maintain stability on narrow branches is often presented as a major selective force shaping primate morphology, with adaptations to facilitate grasping receiving particular attention. The functional importance of a long and mobile tail…

With the increase of human activity and corresponding increase in anthropogenic sounds in marine waters of the Arctic, it is necessary to understand its effect on the hearing of marine wildlife. We have conducted a baseline study on the spiral…

We previously demonstrated that the intravenous anesthetic, propofol, restores the sensitivity of transient receptor potential vanilloid channel subtype-1 (TRPV1) receptors via a protein kinase C epsilon (PKCepsilon)-dependent and transient receptor…

BACKGROUND: Ultrasonography is considered the most appropriate initial imaging study in the evaluation of acute appendicitis in children but has recently come under criticism with reports of low specificity and high indeterminate study rates,…

The present study tested a model of socialization to work in the family context and its implications as a lever for school engagement using a sample of 154 parent-youth dyads living in the United States. A path model was fitted to data. Findings…

Heroin-associated stroke is a rare complication of use. Various proposed mechanisms of heroin-associated ischemic stroke have been proposed, including the following: cardioembolism in the setting of infective endocarditis, hypoxic ischemic brain…

Cholesteatoma is a relatively common disease entity within the middle ear cavity, but it is rarely found in the paranasal sinuses. We describe a rare case of cholesteatoma in the maxillary sinus of an elderly man presenting with recurrent sinus…

STUDY OBJECTIVE: Emergency medical services (EMS) personnel frequently use the Glasgow Coma Scale (GCS) to assess injured and critically ill patients. This study assesses the accuracy of EMS providers' GCS scoring, as well as the improvement in GCS…

Mounting research evidence demonstrates a significant negative impact of circadian disruption on human health. Shift work, chronic jet lag and sleep disturbances are associated with increased incidence of metabolic syndrome, and consequently result…

Complete bone marrow infiltration with profound pancytopenia is very uncommon in breast cancer. Bone marrow metastasis can frequently occur following development of metastatic breast cancer. However, bone marrow failure as the herald of this disease…

Much work has been done to unveil the mechanisms behind the pathogenesis of dermatomyositis (DM) - mainly those involving certain pathogenic cytokines, termed "pathokines" as the principal cytokines involved. Recently, it has become clear that a…
