Gas transport mechanisms during high-frequency ventilation.

By virtue of applying small tidal volumes, high-frequency ventilation is advocated as a method of minimizing ventilator-induced lung injury. Lung protective benefits are established in infants, but not in other patient cohorts. Efforts to improve and extend the lung protection potential should consider how fundamental modes of gas transport can be exploited to minimize harmful tidal volumes while maintaining or improving ventilation.

Selenium Disulfide from Sustainable Resources: An Example of "Redneck" Chemistry with a Pinch of Salt.

Selenium disulfide (often referred to as SeS) encompasses a family of mixed selenium-sulfide eight-membered rings, traditionally used as an anti-dandruff agent in shampoos. SeS can be produced by reacting hydrogen sulfide (HS) with selenite (SeO) under acidic conditions. This chemistry is also possible with natural spring waters that are rich in HS, thus providing an avenue for the more sustainable, green production of high-quality SeS particles from an abundant natural source.

Management of a Patient With an Anomalous Right Coronary Artery: A Case Report.

Coronary artery anomalies are rare congenital defects that involve abnormalities in the origin, course, or termination of the three main epicardial coronary arteries. Due to the variety of aberrant coronary artery defects, the clinical presentation can differ. Anomalous origins of the right coronary artery include the pulmonary trunk, ascending aorta, left sinus of Valsalva, and a course that traverses between the great vessels.

In the realm of innovative medical procedures, TEER (transcatheter edge-to-edge repair) has emerged as a promising field, showcasing significant growth and advancements. Mitral TEER has been performed for the last two decades; in contrast, tricuspid TEER is newer, with long-term outcomes pending. This article aims to provide a comprehensive review of the current literature, with a primary focus on outcomes and potential complications associated with both procedures.

Comparison of intra-operative skull fixation techniques on cervical sagittal parameters.

Background: There is limited literature concerning the use of bi-vector traction to a Mayfield following posterior cervical fusion with respect to cervical alignment parameters. The objective of this study was to determine how variability of intra-operative fixation methods for posterior cervical fusion affects post-operative cervical sagittal alignment parameters.

Methods: After institutional review board (IRB) approval, retrospective chart review of a total of 54 patients who underwent posterior cervical fusion from July 2017 to December 2019 was conducted.

Protein-Ligand Interaction Energies from Quantum-Chemical Fragmentation Methods: Upgrading the MFCC-Scheme with Many-Body Contributions.

Quantum-chemical fragmentation methods offer an attractive approach for the accurate calculation of protein-ligand interaction energies. While the molecular fractionation with conjugate caps (MFCC) scheme offers a rather straightforward approach for this purpose, its accuracy is often not sufficient. Here, we upgrade the MFCC scheme for the calculation of protein-ligand interactions by including many-body contributions.

Hybrid Quadrupole Mass Filter-Radial Ejection Linear Ion Trap and Intelligent Data Acquisition Enable Highly Multiplex Targeted Proteomics.

Targeted mass spectrometry (MS) methods are powerful tools for the selective and sensitive analysis of peptides identified in global discovery experiments. Selected reaction monitoring (SRM) is the most widely accepted clinical MS method due to its reliability and performance. However, SRM and parallel reaction monitoring (PRM) are limited in throughput and are typically used for assays with around 100 targets or fewer.

Antioxidants: A Hot Controversy Defused by Cool Semantics.

Recent years have witnessed a rather controversial debate on what antioxidants are and how beneficial they may be in the context of human health. Despite a considerable increase in scientific evidence, the matter remains highly divisive as different pieces of new data seem to support both the pro- and the anti-antioxidant perspective. Here, we argue that the matter at the heart of this debate is not necessarily empirical but of semantics.

Measurement variability of blood-brain barrier permeability using dynamic contrast-enhanced magnetic resonance imaging.

Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is used to quantify the blood-brain barrier (BBB) permeability-surface area product. Serial measurements can indicate changes in BBB health, of interest to the study of normal physiology, neurological disease, and the effect of therapeutics. We performed a scan-rescan study to inform both sample size calculation for future studies and an appropriate reference change value for patient care.

Biocatalytic Ether Lipid Synthesis by an Archaeal Glycerolprenylase.

Although ethers are common in secondary natural products, they are an underrepresented functional group in primary metabolism. As such, there are comparably few enzymes capable of constructing ether bonds in a general fashion. However, such enzymes are highly sought after for synthetic applications as they typically operate with higher regioselectivity and under milder conditions than traditional organochemical approaches.

Cellular and extracellular proteomic profiling of paradoxical low-flow low-gradient aortic stenosis myocardium.

Aims: Patients with severe aortic stenosis (AS), low transvalvular flow (LF) and low gradient (LG) with normal ejection fraction (EF)-are referred to as paradoxical LF-LG AS (PLF-LG). PLF-LG patients develop more advanced heart failure symptoms and have a worse prognosis than patients with normal EF and high-gradient AS (NEF-HG). Despite its clinical relevance, the mechanisms underlying PLF-LG are still poorly understood.

Nuclease-Resistant L-DNA Tension Probes Enable Long-Term Force Mapping of Single Cells and Cell Consortia.

DNA-based tension probes with precisely programmable force responses provide important insights into cellular mechanosensing. However, their degradability in cell culture limits their use for long-term imaging, for instance, when cells migrate, divide, and differentiate. This is a critical limitation for providing insights into mechanobiology for these longer-term processes.
