Influence of aqueous solutions of 2-(tetrafluoro(trifluoromethyl)-λ-sulfanyl-ethan-1-ol (CFSF-ethanol) on the stabilization of the secondary structure of melittin: comparison with aqueous trifluoroethanol using molecular dynamics simulations and circular dichroism experiments.

The influence of aqueous solutions of 2-(tetrafluoro(trifluoromethyl)-λ-sulfanyl-ethan-1-ol (CFSF-ethanol) and 2,2,2-trifluoroethanol (TFE) on the secondary structure of melittin was studied using circular dichroism (CD) and molecular dynamics (MD) simulations. In water, melittin transitions into a random coil. However, upon addition of even as little as 1% by volume of CFSF-ethanol, the secondary structure of melittin stabilizes as a helix.

Physiologically Based Pharmacokinetic Modeling of Cannabidiol, Delta-9-Tetrahydrocannabinol, and Their Metabolites in Healthy Adults After Administration by Multiple Routes.

The two most extensively studied cannabinoids, cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC), are used for myriad conditions. THC is predominantly eliminated via the cytochromes P450 (CYPs), whereas CBD is eliminated through both CYPs and UDP-glucuronosyltransferases (UGTs). The fractional contributions of these enzymes to cannabinoid metabolism have shown conflicting results among studies.

Longitudinal associations between intersectional stigmas, antiretroviral therapy adherence, and viral load among women living with HIV using multidimensional latent transition item response analysis.

Background: In the US, Women, especially Black and Latina women living in disadvantaged environments, are disproportionally affected by HIV. Women living with HIV (WLHIV) have higher rates of suboptimal antiretroviral therapy (ART) adherence, and detectable viral load (VL). Experiences of intersectional poverty, HIV, gender, and racial stigmas may increase the rates of detectable VL through suboptimal ART adherence.

Development of a rapid screener to elicit patient preferences for antiseizure medication discontinuation.

Objective: While guidelines encourage individualized discussions of the risks and benefits of antiseizure medication (ASM) withdrawal after a period of seizure-freedom, no formal methods exist for assessing patient preferences. We report the initial development of a rapid patient preferences screener.

Methods: We conducted a mixed-methods study of adults who were ≥1 year seizure-free and seen for epilepsy across three institutions.

Emotion recognition using multi-scale EEG features through graph convolutional attention network.

Emotion recognition via electroencephalogram (EEG) signals holds significant promise across various domains, including the detection of emotions in patients with consciousness disorders, assisting in the diagnosis of depression, and assessing cognitive load. This process is critically important in the development and research of brain-computer interfaces, where precise and efficient recognition of emotions is paramount. In this work, we introduce a novel approach for emotion recognition employing multi-scale EEG features, denominated as the Dynamic Spatial-Spectral-Temporal Network (DSSTNet).

Non-detection of emerging and re-emerging pathogens in wastewater surveillance to confirm absence of transmission risk: A case study of polio in New York.

Infectious disease surveillance systems, including wastewater surveillance, can alert communities to the threat of emerging pathogens. We need methods to infer understanding of transmission dynamics from non-detection. We estimate a sensitivity of detection of poliovirus in wastewater to inform the sensitivity of wastewater surveillance for poliovirus using both a clinical epidemiology and fecal shedding approach.

Reconciling heterogeneous dengue virus infection risk estimates from different study designs.

Uncovering rates at which susceptible individuals become infected with a pathogen, i.e., the force of infection (FOI), is essential for assessing transmission risk and reconstructing distribution of immunity in a population.

A guide to building a low-cost centrifuge force microscope module for single-molecule force experiments.

The ability to apply controlled forces to individual molecules or molecular complexes and observe their behaviors has led to many important discoveries in biology. Instruments capable of probing single-molecule forces typically cost >US$100,000, limiting the use of these techniques. The centrifuge force microscope (CFM) is a low-cost and easy-to-use instrument that enables high-throughput single-molecule studies.

Selective engagement of long-latency reflexes in postural control through wobble board training.

Long-latency reflexes (LLRs) are critical precursors to intricate postural coordination of muscular adaptations that sustain equilibrium following abrupt disturbances. Both disturbances and adaptive responses reflect excursions of postural control from quiescent Gaussian stability under a narrow bell curve, excursions beyond Gaussianity unfolding at many timescales. LLRs slow with age, accentuating the risk of falls and undermining dexterity, particularly in settings with concurrent additional tasks.

Small-angle scattering interferometry with neutron orbital angular momentum states.

Methods to prepare and characterize neutron helical waves carrying orbital angular momentum (OAM) were recently demonstrated at small-angle neutron scattering (SANS) facilities. These methods enable access to the neutron orbital degree of freedom which provides new avenues of exploration in fundamental science experiments as well as in material characterization applications. However, it remains a challenge to recover phase profiles from SANS measurements.

A comprehensive benchmark study of methods for identifying significantly perturbed subnetworks in cancer.

Network-based methods utilize protein-protein interaction information to identify significantly perturbed subnetworks in cancer and to propose key molecular pathways. Numerous methods have been developed, but to date, a rigorous benchmark analysis to compare the performance of existing approaches is lacking. In this paper, we proposed a novel benchmarking framework using synthetic data and conducted a comprehensive analysis to investigate the ability of existing methods to detect target genes and subnetworks and to control false positives, and how they perform in the presence of topological biases at both gene and subnetwork levels.

Visible Light-Driven Excited-State Copper-BINAP Catalysis for Accessing Diverse Chemical Reactions.

The use of visible light to drive chemical transformations has a history spanning over a century. However, the development of photo-redox catalysts to efficiently harness light energy is a more recent advancement, evolving over the past two decades. While ruthenium and iridium-based photocatalysts dominate due to their photostability, long excited-state lifetimes, and high redox potentials, concerns about sustainability and cost have shifted attention to first-row transition metals.

Recurrent Intussusception in a Pediatric Patient: The Role of the Mesoappendix as a Potential Culprit.

Intussusception, a condition in which one part of the intestine telescopes into another, primarily affects children under 18 months of age. This case report details the radiologic findings in a six-year-old child with a long-standing history of recurrent ileocolic intussusception, who presented with abdominal pain and was diagnosed with intussusception-associated appendicitis. Following the fifth recurrence, the patient underwent laparoscopic reduction of the intussusception and appendectomy.

E-cigarettes and arterial health: A review of the link between vaping and atherosclerosis progression.

Recent studies have suggested an evolving understanding of the association between vaping, specifically electronic cigarette (e-cigarette) use, and the progression of atherosclerosis, a significant contributor to cardiovascular disease. Despite the prevailing perception of vaping as a safer alternative to traditional tobacco smoking, accumulating evidence suggests that the aerosols emitted by e-cigarettes contain harmful constituents that may promote endothelial dysfunction, oxidative stress, inflammation, and dyslipidemia-key mechanisms implicated in atherosclerosis pathogenesis. While past research, including experimental studies and clinical investigations, has shed light on the potential cardiovascular risks associated with vaping, gaps in knowledge persist.
