Ethanol and the Limitations of the Osmol Gap.

Study Objective: The osmol gap can help detect and manage those with toxic alcohol exposure, and it is altered by all alcohols including ethanol. The optimal correction for ethanol that would allow accurate detection of an alternative alcohol is unclear.

Methods: We conducted a prospective cohort study to assess baseline variations in osmol gap, and then to assess the validity of 2 commonly used coefficients (correction factors) for ethanol.

Global metabolomic alterations associated with endocrine-disrupting chemicals among pregnant individuals and newborns.

Background: Gestational exposure to non-persistent endocrine-disrupting chemicals (EDCs) may be associated with adverse pregnancy outcomes. While many EDCs affect the endocrine system, their effects on endocrine-related metabolic pathways remain unclear. This study aims to explore the global metabolome changes associated with EDC biomarkers at delivery.

Human response times are governed by dual anticipatory processes with distinct neural signatures.

Human behavior is strongly influenced by anticipation, but the underlying neural mechanisms are poorly understood. We obtained intracranial electrocephalography (iEEG) measurements in neurosurgical patients as they performed a simple sensory-motor task with variable (short or long) foreperiod delays that affected anticipation of the cue to respond. Participants showed two forms of anticipatory response biases, distinguished by more premature false alarms (FAs) or faster response times (RTs) on long-delay trials.

Enhanced optical properties of chitosan polymer doped with orange peel dye investigated via UV-Vis and FTIR analysis.

The current research aims to determine the impact of orange peel dye (OPD), an eco-friendly addition, on the optical properties of biodegradable polymers. This study investigates the enhancement of optical properties in solid electrolytes based on chitosan (CS) and glycerol, with varying OPD concentrations. UV-Vis-NIR spectroscopy revealed significantly enhanced UV-visible light absorption in the 200-500 nm region and effective UV light blocking.

Ultra high density imaging arrays in diffuse optical tomography for human brain mapping improve image quality and decoding performance.

Functional magnetic resonance imaging (fMRI) has dramatically advanced non-invasive human brain mapping and decoding. Functional near-infrared spectroscopy (fNIRS) and high-density diffuse optical tomography (HD-DOT) non-invasively measure blood oxygen fluctuations related to brain activity, like fMRI, at the brain surface, using more-lightweight equipment that circumvents ergonomic and logistical limitations of fMRI. HD-DOT grids have smaller inter-optode spacing (~ 13 mm) than sparse fNIRS (~ 30 mm) and therefore provide higher image quality, with spatial resolution ~ 1/2 that of fMRI, when using the several source-detector distances (13-40 mm) afforded by the HD-DOT grid.

Developmental deficits, synapse and dendritic abnormalities in a Clcn4 KO autism mice model: endophenotypic target for ASD.

Autism spectrum disorder (ASD) is linked to ion channel dysfunction, including chloride voltage-gated channel-4 (CLCN4). We generated Clcn4 knockout (KO) mice by deleting exon 5 of chromosome 7 in the C57BL/6 mice. Clcn4 KO exhibited reduced social interaction and increased repetitive behaviors assessed using three-chamber and marble burying tests.

High-resolution fleezers reveal duplex opening and stepwise assembly by an oligomer of the DEAD-box helicase Ded1p.

DEAD-box RNA-dependent ATPases are ubiquitous in all domains of life where they bind and remodel RNA and RNA-protein complexes. DEAD-box ATPases with helicase activity unwind RNA duplexes by local opening of helical regions without directional movement through the duplexes and some of these enzymes, including Ded1p from Saccharomyces cerevisiae, oligomerize to effectively unwind RNA duplexes. Whether and how DEAD-box helicases coordinate oligomerization and unwinding is not known and it is unclear how many base pairs are actively opened.

Neonatal and Pediatric Pulmonary Vascular Disease.

Pediatric patients are affected by a wide variety of pulmonary vascular diseases ranging from congenital anomalies diagnosed at birth to acquired diseases that present later in childhood and into adolescence. While some pulmonary vascular diseases present similarly to those seen in adults, other forms are unique to children. Knowledge of the characteristic imaging features of these diseases is essential to facilitate prompt diagnosis and guide clinical management.

Opioid Consumption Following Isolated and Recurrent Shoulder Dislocation and Reduction.

Background: Recurrent shoulder dislocations often lead to multiple encounters for reduction and eventual surgical stabilization, both of which involve exposure to opioids and potentially increase the risk of chronic opioid exposure. The purpose of our study was to characterize shoulder instability and compare pre- and post-reduction opioid usage in singular dislocators (SD) and recurrent dislocators (RD).

Methods: This retrospective study was performed at a single academic institution using a prospective database.

Effects of Different Humeral Stem Length on Stem Alignment and Proximal Stress Shielding in Reverse Total Shoulder Arthroplasty.

Background: Few comparative studies on the correlation between stem length, stem alignment, and/or stress shielding have been conducted in reverse total shoulder arthroplasty (rTSA). This study aimed to investigate the effects of different humeral stem lengths on stem alignment and proximal stress shielding after rTSA.

Methods: A total of 320 patients who underwent primary rTSA from October 2010 to May 2020 with at least 2 years of follow-up (mean follow-up: 32.

The exploration of the relationship between hyperuricemia, gout and Vitamin D deficiency.

Background: Our study aims to provide evidence concerning the relationship between hyperuricemia, gout and Vitamin D deficiency by analyzing data from Peking Union Medical College Hospital (PUMCH), the National Health and Nutrition Examination Survey (NHANES) database, and through Mendelian randomization (MR) analyses.

Methods: Sample 1 involved patients from PUMCH (n=13,532), and sample 2 involved participants from NHANES (Unweighted n=22,860; weight n=182,829,142). Logistic regression and restricted cubic spline analyses were applied to assess above relationship.

Racial and ethnic enrollment disparities in clinical trials leading to FDA approvals for gynecologic malignancies.

Background: Black women and other minorities have higher age adjusted incidence risk for cervical and endometrial cancer than White women. However, the extent of racial and ethnic disparities in clinical trial enrollment among studies performed mainly in North America and Europe for gynecologic malignancy is unknown.

Objective: This study analyzed enrollment rates by race/ethnicity in trials that led to Food and Drug Administration (FDA) approvals for gynecological cancers from 2010 to 2024.

Associations of the serum 25-hydroxyvitamin D with mortality among patients in osteopenia or osteoporosis.

Purpose: The correlation between serum vitamin D and mortality in patients with osteopenia or osteoporosis remains unclear. Therefore, this study examined the relationship between serum 25-hydroxy vitamin D [(25(OH)D] and mortality in patients with osteopenia or osteoporosis.

Methods And Result: This prospective cohort study included patients with osteopenia or osteoporosis from the National Health and Nutrition Examination Survey from 2001 to 2018.

Preparation of gangue-based PKSPGM@ZHS and photocatalytic synergistic adsorption of Ph Photocatalytic synergistic adsorption performance study.

For the effective removal of phenol from the environment, photocatalytic synergistic adsorption is currently one of the key methods. By leveraging the polysaccharide backbone structure of sodium alginate (SA),Zinc hydroxystannate (ZHS) was introduced into the gel structure using a co-precipitation technique. Additionally, gangue waste was repurposed through a polymerization reaction.

FeS@BC prepared from natural pyrite and biomass as peroxydisulfate activator for sulfadiazine degradation.

The efficient degradation of SAs is a significant challenge for the treatment of wastewater. To address this, the FeS@BC was prepared by calcining a mixture of pyrite and biomass, and used to activate peroxydisulfate (PDS) to degrade sulfadiazine (SDZ). The effect of carbon sources (wheat straw, rice husk, and corn cob) on catalytic activity of FeS@BC were investigated by Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), total Fe dissolution and free radical quantification.

Two-in-one strategy to enhance the stability of TiCT in transition metal ion solutions.

Although MXenes have attracted significant attention across diverse fields, they exhibit a pronounced susceptibility to oxidation in aqueous environments, with oxidation significantly accelerated in the presence of transition metal ions (TMI) such as Fe and Cu. This limitation impedes the synthesis of transition metal compounds/MXene-based composites and their potential for functional applications. In this study, we elucidate the mechanism of accelerated oxidation of TiCT is that Fe promotes the electron loss in TiCT, thus leading to an increased production of hydroxyl radicals (OH) to oxidize TiCT.

Near-infrared-triggered release of self-accelerating cascade nanoreactor delivered by macrophages for synergistic tumor photothermal therapy/starvation therapy/chemodynamic therapy.

Macrophages have emerged as promising cellular vehicles for the delivery of therapeutic agents to tumor sites. However, the cytotoxicity of therapeutic agents toward the cellular carriers and the effective release of therapeutic agents at the tumor site remain the main challenges faced by macrophage-mediated drug delivery systems. Herein, a near-infrared (NIR)-triggered release of self-accelerating cascade nanoreactor (HCFG) delivered by macrophages (HCFG@R) was developed for synergistic tumor photothermal therapy (PTT)/starvation therapy (ST)/chemodynamic therapy (CDT).

Enhanced degradation of sulfamethoxazole in water by biochar loading and multiple free and non-free radicals cooperating in the FeS@BC/PS system.

The excessive consumption of sulfamethoxazole (SMX), a pharmaceutical antibiotic, poses significant environmental hazards. The FeS-persulfate (FeS-PS) system has been employed for SMX remediation because of its excellent performance. However, FeS tends to agglomerate and become passivated, negatively impacting its activation performance.

Estrogenic and anti-estrogenic assessment of the flame retardant, 2-ethylhexyl diphenyl phosphate (EHDPP), and its metabolites: Evidence from in vitro, in silico, and transcriptome studies.

2-Ethylhexyl diphenyl phosphate (EHDPP) is a replacement flame-retardant commonly found in several environmental matrices and human biospecimens. Although some adverse effects of EHDPP have been identified, the endocrine-disrupting effects of EHDPP and its key metabolites on the human estrogen receptor (ER) are largely unknown. Herein, we report for the first time that EHDPP, at concentrations found in the environment and humans, significantly promoted estrogenic activity and synergized with 17β-estradiol-induced ER transactivation.

Degradation and defluorination of CF PFASs with different functional groups by VUV/UV-based reduction and oxidation processes.

Structural diversity can affect the degradability of per- and polyfluoroalkyl substances (PFASs) during water treatment. Here, three PFASs with different functional groups-CF-R, PFHpA, PFHxS, and 6:2 FTS-were degraded using vacuum ultraviolet (VUV/UV)-based treatments. While fully fluorinated PFASs-PFHpA and PFHxS-were degraded faster in the VUV/UV/sulfite reaction than in VUV/UV photolysis, VUV/UV photolysis was more effective for degrading 6:2 FTS by OH radicals produced through photolysis of water.
