Simulating polar bear energetics during a seasonal fast using a mechanistic model

PloS One

Sep 11, 2013

Paul D Mathewson, Warren P Porter

Abstract

In this study we tested the ability of a mechanistic model (Niche Mapper™) to accurately model adult, non-denning polar bear (Ursus maritimus) energetics while fasting during the ice-free season in the western Hudson Bay. The model uses a steady state heat balance approach, which calcul...read more

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

DDX3X Syndrome

DDX3X syndrome is caused by a spontaneous mutation at conception that primarily affects girls due to its location on the X-chromosome. DDX3X syndrome has been linked to intellectual disabilities, seizures, autism, low muscle tone, brain abnormalities, and slower physical developments. Here is the latest research.

Asperger Syndrome

Asperger syndrome (AS), also known as Asperger's, is a developmental disorder characterized by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behavior and interests. Discover the latest research on Asperger syndrome here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

COVID-19 & Diabetes (ADA)

COVID-19 (short for “Coronavirus Disease 2019") is the disease caused by the novel coronavirus, SARS-CoV-2. Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. COVID-19 represents a particular challenge to people with serious chronic medical conditions such as diabetes. To keep our community as informed as possible, the American Diabetes Association is partnering with the Chan Zuckerberg Initiative's Meta to highlight the latest research developments at the intersection of COVID-19 and diabetes.

Omics in Myocardial Infarction

Omics' methods are used to understand the gene expression profile and proteomics of many diseases. This feed focuses on omics analyses of myocardial infarction. Here are the latest discoveries pertaining to this disease.

Severe Acute Respiratory Syndrome

Severe acute respiratory syndrome (SARS) is a viral respiratory disease of zoonotic origin caused by the SARS coronavirus (SARS-CoV). Initial symptoms are flu-like and may include fever, muscle pain, lethargy symptoms, cough, sore throat, and other nonspecific symptoms. SARS may eventually lead to shortness of breath and pneumonia; either direct viral pneumonia or secondary bacterial pneumonia. DIscover the latest research on SARS here.
