Glycemic control after aortic valve replacement: A retrospective study.

Background: Aortic stenosis (AS) is treated through transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR), with diabetes being prevalent among these patients. Inflammation participates in the pathogenesis of AS, and emerging evidence suggests that TAVI may exert anti-inflammatory effects. Given the established link between diabetes and inflammation, we sought to evaluate the impact of aortic valve replacement (AVR) on glycemic control.

Effects of vitamin D supplementation on cardiac biomarkers: Results from the STURDY trial.

Objectives: In observational studies, older adults with low serum vitamin D levels are at higher risk of cardiovascular disease (CVD), but randomized trials have failed to demonstrate reduction in CVD risk from vitamin D supplementation, possibly because the doses of vitamin D supplements tested were too low. Our objective was to determine if higher doses of vitamin D supplementation reduce high-sensitivity cardiac troponin (hs-cTnI) and N-terminal pro-b-type natriuretic peptide (NT-proBNP), markers of subclinical CVD.

Methods: The Study to Understand Fall Reduction and Vitamin D in You (STURDY) was a double-blind, randomized, response-adaptive trial that tested the effects of 4 doses of vitamin D3 supplementation (200, 1000, 2000, 4000 IU/day) on fall risk among older adults with low serum 25-hydroxyvitamin D concentrations (10-29 ng/mL).

Label-free imaging flow cytometry for cell classification based directly on multiple off-axis holographic projections.

Significance: Imaging flow cytometry allows highly informative multi-point cell analysis for biological assays and medical diagnosis. Rapid processing of the imaged cells during flow allows real-time classification and sorting of the cells. Off-axis holography enables imaging flow cytometry without chemical cell staining but requires digital processing to the optical path delay profile for each frame before the cells can be classified, which slows down the overall processing throughput.

Food and agricultural commodities endure consistent contamination by mycotoxins, low molecular weight fungal metabolites, which pose severe health implications to humans together with staggering economic losses. Herein, a ratiometric aptasensor was constructed using silver-coated porous silicon (Ag-pSi) used as an efficient surface-enhanced Raman scattering (SERS) substrate. The bioassay included direct detection of fumonisin B (FB), an abundant and widespread contaminant, by a specific aptamer sequence immobilized on the porous transducer.

De-novo Genome Assembly of the Edwardsiid Anthozoan Edwardsia elegans.

Cnidarians (sea anemones, corals, hydroids, and jellyfish) are a key outgroup for comparisons with bilaterial animals to trace the evolution of genomic complexity and diversity within the animal kingdom, as they separated from most other animals 100s of millions of years ago. Cnidarians have extensive diversity, yet the paucity of genomic resources limits our ability to compare genomic variation between cnidarian clades and species. Here we report the genome for Edwardsia elegans, a sea anemone in the most specious genus of the family Edwardsiidae, a phylogenetically important family of sea anemones that contains the model anemone Nematostella vectensis.

A Dual-Pathway Responsive Mechanophore for Intelligent Luminescent Polymer Materials.

Mechanoluminescent units, when integrated into polymer matrices, undergo structural transformations in response to mechanical force, resulting in changes in fluorescence. This phenomenon holds considerable promise for the development of stress-sensing materials. Despite the high demand for robust, tunable mechanoluminescent mechanophores for force assessment and smart force-responsive materials, strategies for their design and synthesis remain underdeveloped.

Hormone circuit explains why most HPA drugs fail for mood disorders and predicts the few that work.

Elevated cortisol in chronic stress and mood disorders causes morbidity including metabolic and cardiovascular diseases. There is therefore interest in developing drugs that lower cortisol by targeting its endocrine pathway, the hypothalamic-pituitary-adrenal (HPA) axis. However, several promising HPA-modulating drugs have failed to reduce long-term cortisol in mood disorders, despite effectiveness in other hypercortisolism conditions such as Cushing's syndrome.

Beta-tricalcium phosphate patient-specific gap implants in bilateral sagittal split osteotomy: an innovative treatment method to enhance the mandibular border contour. Part 1: concept and workflow.

Antegonial notching can occur after bilateral sagittal split osteotomy (BSSO) and may lead to unpleasant aesthetic outcomes in both young and older patients. This clinical study presents a new concept to potentially overcome this problem and describes the workflow. Beta-tricalcium phosphate patient-specific gap implants (β-TCP gap-PSIs) are biocompatible and resorbable bone grafts that are placed in the space of the osteotomy gap during orthognathic procedures; they are virtually planned and printed in 3D.

The effect of occlusion on the visual working memory pointer-system.

To access its online representations, visual working memory (VWM) relies on a pointer-system that creates correspondence between objects in the environment with their memory representations. This pointer-system allows VWM to modify its representations using a process called updating. When the pointer is invalidated, however, VWM triggers a process called resetting in which the no longer relevant representation and pointer are replaced.
