This article reads two early twentieth-century American novels, William Maxwell’s They Came Like Swallows (1937) and Katherine Anne Porter’s Pale Horse, Pale Rider (1939), in relation to the Spanish flu pandemic of 1918–19 and the history of public…

Background: Isocitrate dehydrogenase-1 (IDH1) mutation is now an established early event in gliomagenesis. The ability to detect this mutation by several techniques including immunohistochemistry makes it a significant marker for diagnosing and…

INTRODUCTION: Since its discovery in Wuhan, China in December of 2019, the novel Coronavirus has progressed to become one of the worst pandemics seen in the last 100 years. Recently the gastrointestinal manifestations of COVID-19 have been well…

INTRODUCTION: Fibrosis & nonalcoholic steatohepatitis (NASH) are important predictors of long term prognosis in patients with non-alcoholic fatty liver disease (NAFLD). Oxidative stress (OS) has been shown to play a central role in progression of…

Background Abnormalities of right ventricular (RV) strain have been shown to occur prior to impairment of global right ventricular function, measured by global RV ejection fraction (RVEF) in patients with increased RV afterload, such as pulmonary…

Background: Empathy is critical for optimal patient experience with health-care providers. Verbal empathy is routinely taught to medical students, but nonverbal empathy, including touch, less so. Our objective was to determine whether instruction…

Breech presentation complicates as many as 4% of all deliveries. External cephalic version (ECV) is a procedure that involves the external rotation of the fetus through the mother's abdomen from a breech position into a cephalic position. It provides…

Purpose Over the past decade, an increasing number of bariatric surgeons are trained in fellowships annually despite only a modest increase in nationwide bariatric surgery volume. The study surveys the bariatric surgery job market trend in order to…

Uterine carcinosarcoma (USC) is a rare, aggressive primary neoplasm of the Uterus that represents less than 5% of all uterine malignancies. It usually affects older females in their seventh decade. USC disproportionally affects black women more and…

Adult day centers (ADCs) are nonresidential settings that support the health and social needs of vulnerable older adults. Due to ADCs' congregate nature and participants' compromised health status, many ADCs have been forced to close during the…

This manuscript describes the abrupt pivot of VQI physician members away from standard clinical practice to a restrictive phase of emergent and urgent vascular procedures in response to the pandemic. The Society for Vascular Surgery Patient Safety…

The pattern of bone remodeling of one of the most peculiar mammals in the world, the naked mole-rat (NMR), was assessed. NMRs are known for their long lifespans among rodents and for having low metabolic rates. We assessed long-term in vivo bone …

Rationale: Voltage-gated potassium (Kv) channels in vascular smooth muscle are essential for coupling myocardial blood flow (MBF) with the metabolic demand of the heart. These channels consist of a transmembrane pore domain that associates with …

In response to the pandemic, an abrupt pivot of VQI physician members away from standard clinical practice to a restrictive phase of emergent and urgent vascular procedures occurred. The Society for Vascular Surgery Patient Safety Organization …

Cardiovascular disease (CVD) is among the leading causes of death worldwide. Micro-RNAs (miRNAs), regulatory molecules that repress protein expression, have attracted considerable attention in CVD research. The vasculature plays a big role in CVD…

Synaptic and neuronal loss are major neuropathological characteristics of Parkinson's disease (PD). Misfolded protein aggregates in the form of Lewy bodies, comprised mainly of α-synuclein (αSyn), are associated with disease progression, and have…

INTRODUCTION: Oxygen uptake efficiency slope (OUES) is a non-invasive cardiopulmonary exercise testing (CPET) measurement based on oxygen uptake (V&c.dotab;O(2) ) and minute ventilation (V&c.dotab;(E) ) and is a marker of the efficiency of oxygen…

OBJECTIVES: To determine whether current guidelines emphasizing antibiotic stewardship in pediatrics have been associated with reduced prevalence of antibiotic allergies in children severely affected by otitis media undergoing bilateral myringotomy…

BACKGROUND: ultrasound-based shear wave elastography (SWE) can non-invasively assess prostate tissue stiffness. This systematic review aims to evaluate SWE for the detection of prostate cancer (PCa) and compare diagnostic estimates between studies …

BACKGROUND: The field of pediatric palliative care (PPC) continues to encounter challenges and opportunities to improving access to high-quality PPC services. In early 2019, a workshop identified eleven potential "next step" actions, and …

OBJECTIVES: In many primates, the greater proportion of climbing and suspensory behaviors in the juvenile repertoire likely necessitates good grasping capacities. Here, we tested whether very young individuals show near-maximal levels of grasping …

Propofol is a widely used sedative for gastrointestinal endoscopic procedures. Drug-induced pancreatitis is a relatively rare disease possibly because of poor recognition. Propofol-induced pancreatitis is an extremely rare phenomenon. We present a…

Activating transcription factor (ATF)3 is known to have an anti-inflammatory function, yet the role of hepatic ATF3 in lipoprotein metabolism or atherosclerosis remains unknown. Here we show that overexpression of human ATF3 in hepatocytes reduces…

PURPOSE: To assess for a positive results bias in recently published randomized controlled trials (RCTs) in the field of vitreoretinal disease.Methods: A bibliometric analysis was conducted examining RCTs published in the field of retina between…

The critical role of primary care clinicians (PCCs) in Alzheimer's disease (AD) prevention, diagnosis and management must evolve as new treatment paradigms and disease-modifying therapies (DMTs) emerge. Our understanding of AD has grown …

BACKGROUND CONTEXT: The New England Spinal Metastasis Score (NESMS) was proposed as an intuitive and accessible prognostic tool for predicting survival in patients with spinal metastases. We designed an appropriately powered, prospective,…

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…

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,…

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…

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…

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…

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…

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 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…

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,…

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…
