A Survey of Minimally Invasive Surfactant Use in the United States.

Objective:  Minimally invasive surfactant therapy (MIST) has become the standard of care in delivering surfactant noninvasively in many parts of the world, particularly throughout Europe; however, centers in the United States have been slower to adopt it. The most recent assessment of the use of MIST in the United States was in 2018 by Kurepa et al. Considering the increasing evidence favoring MIST, this paper reassessed the current rate of utilization and aims to examine barriers to MIST implementation.

Photonic Aptasensor Based on the Smart Cholesteric Liquid Crystal Network Structure for Cylindrospermopsin Detection.

Solid-state cholesteric liquid crystals (CLC) with one-dimensional photonic structure offer a promising platform for constructing chemical and biological optical sensors, owing to their facile fabrication, signal readout, and sensitive and selective responsiveness to target analytes. In this study, we designed a CLC photonic structure intertwined with an interpenetrating polymeric network (IPN) immobilized with a cylindrospermopsin aptamer (CY9) for the selective detection of the cylindrospermopsin toxin (CYT) in water. Upon exposure to CYT, it induced a blue shift in the color of the IPN biosensor chip.

Ultracompact Electrical Double Layers at TiO(110) Electrified Interfaces.

Metal-oxide aqueous interfaces are important in areas as varied as photocatalysis and mineral reforming. Crucial to the chemistry at these interfaces is the structure of the electrical double layer formed when anions or cations compensate for the charge arising from adsorbed H or OH. This has proven extremely challenging to determine at the atomic level.

Androgen Receptor and Non-Coding RNAs' Interaction in Renal Cell Carcinoma.

Renal cell carcinoma (RCC), the most prevalent among the urogenital cancers, accounts for around 3% of new cancer cases worldwide. Significantly, the incidence of RCC has doubled in developed world countries, ranking it as the sixth most common cancer in males, who represent two-thirds of RCC cases. Males with RCC exhibit a higher mortality rate and tend to develop a more aggressive form of the disease than females.

A cohort of 250 patients exhibiting the symptoms of CVD and 50 control subjects participated in this study. After applying the stringent inclusion and exclusion criteria, the diseased group was further stratified into three categories: CVD+ (Alzheimer's disease) AD, CVD + (diabetes mellitus) DM and CVD + DM + AD.

Exploration of newly synthesized deferasirox derivatives as potential anti-cancer agents via in-vitro and in-silico approaches.

Carbonic anhydrase IX (CA IX), upregulated by hypoxia-inducible factor (HIF), plays a crucial role in regulation of intracellular and extracellular pH, which is essential for the growth and spread of tumors. The overexpression of CA IX in breast cancer is linked to a low post-radiation patient survival rate. Under normoxic conditions, CA IX expression is relatively low, but hypoxia-inducible factors (HIFs) upregulate its expression when oxygen levels drop.

RECENT TRENDS IN THE USE OF CELL SALVAGER FOR ORTHOPAEDIC TRAUMA AND ELECTIVE SURGERIES-A NARRATIVE REVIEW.

Intraoperative blood loss management is a critical concern in orthopaedic surgeries, particularly in trauma and complex elective procedures. Traditionally, allogeneic blood transfusions have been used to manage significant blood loss, but they carry risks such as transfusion reactions, infections, and increased healthcare costs. Cell salvage, or autotransfusion, offers a safer alternative by collecting, processing, and reinfusing the patient's own blood during surgery.

Pharmacodynamics and safety in relation to dose and response of plant flavonoids in treatment of cancers.

Despite the recent advancements in developing bioactive nutraceuticals as anticancer modalities, their pharmacodynamics, safety profiles, and tolerability remain elusive, limiting their success in clinical trials. The failure of anticancer drugs in clinical trials can be attributed to the changes in drug clearance, absorption, and cellular responses, which alter the dose-response efficacy, causing adverse health effects. Flavonoids demonstrate a biphasic dose-response phenomenon exerting a stimulatory or inhibitory effect and often follow a U-shaped curve in different preclinical cancer models.

Developing a consistent model for predicting equilibration in polymeric passive samplers across various HOC classes in sediment pore water.

The use of polymeric passive samplers (often polydimethylsiloxane, PDMS, or low-density polyethylene, LDPE) to indicate water concentrations of hydrophobic organic compounds under environmental conditions generally requires two key parameters, a compound-specific polymer-water equilibrium partition coefficient (K), and the degree of equilibration achieved in a given environmental exposure scenario. Herein, we have developed model to extrapolate equilibration of performance reference compounds between polymer and pore water across different compound classes that is also dependent upon accurate estimates of K. We have also developed quantitative structure-activity relationship (QSAR) models, to estimate K for PAHs, PCBs, DDx, and dioxin/furans for the two most common polymeric samplers, PDMS and LDPE.

Search for Soft Unclustered Energy Patterns in Proton-Proton Collisions at 13 TeV.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.
