Functional characterization of the second feedback loop in the circadian clock of the Antarctic krill Euphausia superba.

Background: The Antarctic krill Euphausia superba is a keystone species in the Southern Ocean ecosystem. This crustacean has an ancestral clock whose main components have been identified and characterized in the past few years. However, the second feedback loop, modulating clock gene expression through two transcription factors, VRI and PDP1, has yet to be described.

Evaluating the Impact of an Interprofessional Poverty Virtual Simulation Game.

The aim of the study was to compare the impact of a virtual simulation game to a poverty live interactive simulation with regard to perceptions of poverty. An interprofessional sample of pharmacy and nursing students completed pre/post surveys with 13 questions (total possible score: 39); the 395 responses were analyzed using a two-way analysis of variance and descriptive statistics. The virtual group had a score improvement of 3.

"Pyogenic Spondylodiscitis from Oral Odontogenic Origins: A Frequently Overlooked Entity".

Background Context: Primary spondylodiscitis occurs through the hematogenous spread of a pathogen entering the body via a point of entry. The infection's origin often remains unclear. During dental procedures or through minor traumas, oral bacteria can enter the bloodstream and disseminate throughout the body.

The impact of teledentistry on travel distance and carbon emissions at a children's hospital.

Background: Health care emissions account for approximately 8.5% of total US domestic greenhouse gas emissions. Staff member and patient travel is the largest contributor to dental office-related emissions, and this number has been increasing.

Sirtuin Proteins and Memory: A Promising Target in Alzheimer's Disease Therapy?

Sirtuins (SIRTs), nicotine adenine dinucleotide (+)-dependent histone deacetylases, have emerged as critical regulators in many signalling pathways involved in a wide range of biological processes. Currently, seven mammalian SIRTs have been characterized and are found across a number of cellular compartments. There has been considerable interest in the role of SIRTs in the brain due to their role in a plethora of metabolic- and age-related diseases, including their involvement in learning and memory function in physiological and pathophysiological conditions.
