No licensed vaccine exists against visceral leishmaniasis (VL), a disease caused by the Leishmania donovani parasite. We have previously reported both macrophages and dendritic cells play important role in the protection induced by a live…

Infant mammalian feeding is a complex process that requires the integration of different behaviors and over twenty‐five muscles controlled by multiple cranial nerves. Despite extensive characterization of muscle activity during a feeding sequence,…

Most mammalian pisiforms are large, elongated carpal bones with two ossification centers and an associated growth plate, similar to the calcaneus in the ankle. Short pisiforms are rare among mammals, but can be found in humans, orangutans (Primates:…

Nonalcoholic fatty liver disease (NAFLD) is often characterized by accumulation of lipids in the liver. It presents a pathological spectrum of changes from simple steatosis to steatohepatitis. It is also often associated with obesity and insulin…

Lymphatic anomalies (LA) are rare conditions characterized by abnormal vascularization of lymphatic vessels (lymphangiogenesis). Gorham‐Stout Disease (GSD) is an aggressive type of LA which invades cortical bone and makes it “disappear”. There is…

Vascular smooth muscle cell (VSMC) migration and proliferation, hallmark of SMC phenotypic switching central to the evolution of atherosclerosis, is profoundly enhanced in diabetic patients. Hyperglycemia, characteristic of diabetes, increases…

Cytochrome P450 IV (CYP4) are a family of omega‐hydroxylase enzymes. We have previously shown that these fatty acid omega‐hydroxylases function in the hydroxylation of various chain‐length saturated and unsaturated fatty acids in the endoplasmic…

Well‐developed coronary collaterals prove to be highly beneficial in salvaging ischemic myocardium, preserving cardiac function, and improving patient outcome post‐occlusion. However, this process of coronary collateral growth (CCG) is impaired in…

Metabolic syndrome (MetS) refers to a cluster of anomalies including type 2 diabetes, obesity, insulin resistance and dyslipidemia. Patients with MetS are 1.5 times more likely to develop late‐onset Alzheimer’s Disease (AD), with impaired glucose…

In the United States, coronary heart diseases (CHD) are the leading cause of mortality and morbidity. A well‐developed coronary collateral circulation ameliorates the consequences of CHD, reducing the incidence of sudden death and infarct sizes…

Angiogenesis, the formation of new blood vessels from existing ones, is a normal physiological process. However, deregulation of angiogenesis can lead to pathological states such as cancer, that is characterized by hyper‐permeable and tortuous…

Introduction Diabetic cardiomyopathy (DCM) is a major cardiovascular complication in patients with diabetes and is defined as ventricular dysfunction (in diabetes) independent of coronary artery disease. In this study, we define a novel role for the…

Over the last 50 years progress has been made in treating childhood and adult solid and hematological tumors. One commonly used chemotherapeutic agent is doxorubicin (DOX), an anthracycline antitumor antibiotic, which was discovered in early 1960s.…

Introduction Takotsubo syndrome (TTS), also known as the “Broken Heart Syndrome” or “Apical Ballooning Syndrome is defined by its characteristic anomaly: when the heart contracts during systole, the apex of the heart dilates as the base of the heart…

CASE: A 32-year-old pregnant woman presented with new wrist pain after a fall. She had undergone surgical repair to the same wrist 6 years previously for a distal radius fracture. At that time, there was no evidence of a bone lesion. Current …

In mice, the caller's production of social vocalizations has been extensively studied but the effect of these vocalizations on the listener is less understood, with playback studies to date utilizing one vocalization category or listeners of one sex.…
