Comparison of resting metabolic rate prediction equations in college-aged adults.

Prediction equations have been considered an accurate method for estimating resting metabolic rate (RMR) across multiple populations, but their accuracy for college-aged individuals not on an athletics team remains to be determined. Sixty-two college-aged (18-30 yrs) males ( = 31) and females ( = 31) had their RMR measured (RMRm), using indirect calorimetry, and body composition assessed via air-displacement plethysmography. The World Health Organization (WHO), Mifflin-St Jeor (Mifflin), Harris-Benedict (HB), Cunningham, and Nelson equations were used to estimate RMR.

Cutaneous Cholangiocarcinoma: An Interesting Presentation.

This is a case of a 64-year-old white man with a history of CCA, originally diagnosed in May 2018 and returning in November 2019 with growing cutaneous nodules. These were removed for cosmetic and functional purposes. Pathologic findings of the lesions showed likely metastatic disease from his original CCA.

AVPR1A distribution in the whole C57BL/6J mouse neonate.

The neuropeptide arginine vasopressin (AVP) plays significant roles in maintaining homeostasis and regulating social behavior. In vaginally delivered neonates, a surge of AVP is released into the bloodstream at levels exceeding release during life-threatening conditions such as hemorrhagic shock. It is currently unknown where the potential sites of action are in the neonate for these robust levels of circulating AVP at birth.

Propagation of surface fissures in articular cartilage in response to cyclic loading in vitro.

Background: Mechanical overloading of synovial joints can damage the articular cartilage surface and may lead to osteoarthritis. However, causal links between mechanical and biological events in cartilage are poorly understood.

Objectives: To test the hypothesis that surface fissures in cartilage can propagate mechanically if the joint surface is subjected to vigorous cyclic loading.
