Bowhead whales are some of the largest animals that occupy the Arctic Circle. Despite the challenges of living and giving birth in icy waters, having huge blubber stores, eating a fat-rich diet, and undergoing arduous migrations, bowheads achieved…

In the late 1980s, annual carbon isotope cycles in the baleen plates of bowhead whales formed the basis of the first effective means of estimating bowhead age. However, the baleen aging method could only be used for aging subadult whales less than…

Bering–Chukchi–Beaufort Sea bowhead whales are born at about 4.2m in length and 1000kg, in lead systems along the NW Alaskan coast. Bowheads in the other northern stocks are also born in ice-covered seas. Maximum body lengths (standard measure) can…

Study design is critical to ensure that research questions are answered in an appropriate and rational manner for all aspects of health, but particularly in emergency care. Appropriate study design selection is one of the most critical decisions to…

The skull of the bowhead whale is composed of all the bones commonly found in mammals, although the shape of these bones is far from ordinary. Features related to feeding dominate the skull: there are no teeth, and the rostrum is long and curved,…

Solid organ transplantation in children and adolescents provides many benefits through improving critical organ function, including better growth, development, cardiovascular status, and quality of life. Unfortunately, bone status may be adversely…

Clear and precise writing is a vital skill for healthcare providers and those involved in global emergency care research. It allows one to publish in scientific literature and present oral and written summaries of their work. However, writing skills…

An understanding of the functional morphology of the bowhead whale continues to have significance for population management. This chapter first examines the anatomical features of the bowhead whale reproductive system, with an emphasis on the female.…

The specialty of Emergency Medicine continues to expand and mature worldwide. As a relatively new specialty, the body of research that underpins patient management in the emergency department (ED) setting needs to be expanded for optimum patient…

The commercial hunt of the four stocks of bowhead whales by the nations of Europe and North America commenced in 1540 and came to an effective end at the start of World War I. At that time, all four stocks had been driven to near extinction. Whalers…

We discuss the evolution, phylogenetic relations to right whales, and geographical distribution of bowhead whales. We summarize its relations to humans, including whaling by indigenous and European whalers, conservation efforts, and modern challenges…

The sensory biology of bowhead whales reflects features both related to their origin from land mammals and adaptations to their current environment, polar seas. There is anatomical and genomic evidence that bowheads have a sense of smell. Their sense…

The prenatal development of bowhead whales is poorly known, and no complete ontogenetic series exist. However, the available embryos and fetuses elucidate aspects of the development of the species, as well as that of all of mysticetes in general, and…

The postcranial skeleton of bowhead whales was described in detail more than 100 years ago. The musculature of bowheads has not been studied in detail but matches that of other mysticetes in general features. In this chapter, we focus on some aspects…

Over the past four decades, there have been progressive changes in the epidemiology of traumatic spinal cord injury (tSCI). We assessed trends in demographic and injury-related variables in traumatic cervical spinal cord injury (tCSCI) patients …

Immunofluorescence staining is a widely used and powerful tool for the visualization and colocalization of two or more proteins and/or cellular organelles. For colocalization studies in fixed cells, one target protein/organelle is immunostained and…

Cellular availability of acetyl-CoA, a central intermediate of metabolism, regulates histone acetylation. The impact of a high-fat diet (HFD) on the turnover rates of acetyl-CoA and acetylated histones is unknown. We developed a method for …

Calciphylaxis is a deadly disease that is currently diagnosed through a skin biopsy of resultant necrotic lesions despite many cases lacking this characteristic finding. Recently, research has demonstrated the ability of various radiologic …

Effective critical appraisal of medical research requires training and practice. Evidence-based medicine provides a framework for standardised review of manuscripts of nearly any research design. Online resources and communities exist to provide free…

Cisplatin chemotherapy often causes permanent hearing loss, which leads to a multifaceted decrease in quality of life. Identification of early cisplatin-induced cochlear damage would greatly improve clinical diagnosis and provide potential drug …

Intrinsic properties of neurons are one major determinant for how neurons respond to their synaptic inputs and shape their outputs in neural circuits. Here, we studied the intrinsic properties of neurons in the chicken posterior portion of the…

OBJECTIVE: Our investigation compared throughput metrics and utilization measures for freestanding emergency departments (FSEDs) versus hospital-based emergency departments (HBEDs) of similar volumes in the United States. METHODS: This study is a…

Research is a fundamental component of the development of quality emergency care systems. Developing qualified professionals and programs to conduct emergency care research is essential to understanding epidemiology in low resource settings. This…

Development of a successful research program can seem daunting when looked at from the starting line. It will take years if not decades to succeed and become sustainable. It requires local partnerships and mentoring; it mandates the establishment of…

Scavenger receptor CD36 contributes significantly to lipid homeostasis, inflammation, and amyloid deposition, while CD36 deficiency is associated with restored cerebrovascular function in an Alzheimer's disease (AD) mouse model. Yet the…

Background: Acute kidney injury (AKI) due to urinary stone disease (USD) is rare in adults; AKI rates in children with USD may be higher, and emerging data links stones to chronic kidney disease (CKD) development in adults. Methods: This study is a …

OBJECTIVE: Hyperleptinemia, hallmark of obesity, is a putative pathophysiologic trigger for atherosclerosis. We previously reported a stimulatory effect of leptin on TSP-1 (thrombospondin-1) expression, a proatherogenic matricellular protein …

During the land-to-water transition in the Eocene epoch, the cetacean skeleton underwent modifications to accommodate life in the seas. These changes are well-documented in the fossil record. The forelimb transformed from a weight-bearing limb with…

This paper describes a novel intelligent analysis technique based upon bivariate Markov model that integrates morphological and temporal features with a rule-based interval analysis of ECG signals to localize and accurately classify the premature…

As emergency and acute care systems develop, the ability to broadly engage key stakeholders becomes paramount for success. Collaborating with emergency medicine clinicians as well as other providers who have already developed their specialties,…

Indigenous whalers know a great deal about the habits and environment of bowhead whales. That knowledge is essential for safe and effective hunting and has also been invaluable to scientific research and management of bowheads. Studies in Chukotka,…

Necrotizing soft tissue infection has been historically recognized as a severe, rapidly spreading soft tissue infection associated with a very high risk of mortality. Cases of primary necrotizing fasciitis of the breast are rarely described but…

Presenting research at a conference is an opportunity to disseminate the findings, network with other researchers, and to develop your academic track record. Although every conference will have some local differences, there are common approaches to…

Little is known about the functions of group II metabotropic glutamate receptors (mGluRs2/3) in the inferior colliculus (IC)-a midbrain structure that is a major integration region of the central auditory system. We investigated how these receptors…
