Therapeutic Potential of Dexmedetomidine in Neuropsychiatric Disorders: From the Bench to the Clinic.

Neuropsychiatric disease encompasses a range of conditions resulting from various dysfunctions within the nervous system, manifesting in diverse neurological impairments. These disorders, including depression, schizophrenia, anxiety, and Alzheimer's disease, impose significant economic and psychological burdens on both individuals and society overall. Recent clinical and preclinical studies have highlighted the potential therapy of dexmedetomidine (Dex), a highly selective α2 adrenergic receptor agonist, not only as an effective sedation but also as a neuroprotective agent.

Revisiting the Discrepancy between Experimental and Theoretical Predictions of the Adiabaticity of Ti + CHOH.

We revisit the naked transition metal cation (Ti) and methanol reaction and go beyond the standard Landau-Zener (LZ) picture when modeling the intersystem crossing (ISC) rate between the lowest doublet and quartet states. We use both (i) unconstrained Born-Oppenheimer molecular dynamics (BOMD) calculations with an approximate two-state method to estimate population transfer between spin diabats and (ii) constrained dynamics to explore energetically accessible portions of the - 1 crossing seam, where is the total number of internal degrees of freedom. Whereas previous LZ calculations (that necessarily relied on the Condon approximation to be valid) fell short and predicted much slower crossing probabilities than shown in experiment, we show that ISC can occur rapidly because the spin-orbit coupling (SOC) between the doublet and quartet surfaces can vary by 2 orders of magnitude (depending on where in the seam the crossing occurs during dynamics) and the crossing region is revisited multiple times during a dynamics run of a few hundred femtoseconds.

RETRAGAM: Resistance training based on gamification during physical education. Rationale and study protocol.

Children's physical inactivity and increasing sedentary behaviour have become major public health concerns, with a concurrent decline in muscular fitness (MF) contributing to poor physical outcomes during childhood and adolescence, highlighting the importance of developing resistance training (RT) programs. Furthermore, several educational strategies such as gamification seem to increase students' motivation which can produce an increase in performance outcomes. This study describes the rationale and protocol of a school-based randomized controlled trial called "RETRAGAM" (REsistance TRAining based on GAMification).

Early detection of subjective cognitive decline from self-reported symptoms: An interpretable attention-cost fusion approach.

Background And Objective: Subjective cognitive decline (SCD) refers to self-reported difficulties in concentration, memory, and decision-making. Since SCD is based on subjective experiences, no specific medical test can definitively confirm its presence, making early detection challenging. Thus, it is advantageous to develop an AI model to capitalize on self-reported health complications, personality traits, and sociodemographic factors for early detection of SCD.

The development and validation of a patient questionnaire tool for the assessment of patient-reported experiences with endometriosis ultrasound.

Objective: Endometriosis ultrasound is an accurate, cost-effective, and non-invasive diagnostic tool that can help improve the diagnostic delay that patients with endometriosis experience. As an emerging diagnostic method, the perspectives of patients undergoing endometriosis ultrasound remain unexplored. Therefore, the objective of this study was to develop and validate an assessment tool that evaluates patient-reported experiences with endometriosis ultrasound as a decision-making tool.

Effect of semaglutide 2.4 mg on use of antihypertensive and lipid-lowering treatment in five randomized controlled STEP trials.

Objective: The objective of this study was to assess antihypertensive and lipid-lowering treatment changes in participants receiving semaglutide 2.4 mg versus placebo across pooled populations from five Semaglutide Treatment Effect in People with Obesity (STEP) trials.

Methods: Efficacy and safety of semaglutide 2.

The public health risks of counterfeit pills.

Synthetic illicit drugs, such as nitazenes and fentanyls, are becoming commonplace in countries around the world, including in Europe, Australia, and Latin America, which raises concern for overdose crises like those seen in North America. An important dimension of the risk represented by synthetic drugs is the fact that they are increasingly packaged in counterfeit pill form. These pills-often indistinguishable from authentic pharmaceuticals-have substantially widened the scope of populations susceptible to synthetic drug overdose in North America (eg, among adolescents experimenting with pills or tourists from the USA seeking psychoactive medications from pharmacies in Mexico).

Feruloylacetone and Its Analog Demethoxyferuloylacetone Mitigate Obesity-Related Muscle Atrophy and Insulin Resistance in Mice.

Obesity-induced muscle alterations, such as inflammation, metabolic dysregulation, and myosteatosis, lead to a decline in muscle mass and function, often resulting in sarcopenic obesity. Currently, there are no definitive treatments for sarcopenic obesity beyond lifestyle changes and dietary supplementation. Feruloylacetone (FER), a thermal degradation product of curcumin, and its analog demethoxyferuloylacetone (DFER), derived from the thermal degradation of bisdemethoxycurcumin, have shown potential antiobesity effects in previous studies.

Urinary Kidney Injury Biomarker Profiles in Healthy Individuals and After Nephrotoxic and Ischemic Injury.

Two observational studies were conducted to support an initiative to qualify translational kidney safety biomarkers as clinical drug development tools that identify tubular injury prior to changes in estimated glomerular filtration rate (eGFR). Normal healthy volunteers provided three morning spot urine collections over 4 weeks. Patients undergoing surgical resection and intrathoracic cisplatin for malignant pleural mesothelioma provided urine samples pre- and postoperatively at 4, 8, and 12 hours and daily for 6 days.

BIS Guided Titration of Sevoflurane in Pediatric Patients Undergoing Elective Surgery: A Randomized Controlled Trial.

Background: In pediatric patients, the use of processed EEG monitoring may reduce the amount of anesthesia administered while maintaining adequate depth of anesthesia.

Aims: The primary aim of this study was to evaluate whether use of a BIS monitor to guide sevoflurane administration might reduce the average end tidal sevoflurane concentration used in children 4-18 years of age.

Methods: Participants in three age groups (4-8, 9-12, and 13-18 years) were randomized to either the BIS guided group or the control group.

Land Use Change Consistently Reduces α- But Not β- and γ-Diversity of Bees.

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e.

Histopathologic Features of Acral Skin Biopsies in Dermatomyositis Patients and Comparison to Histopathologic Features in Non-Acral Biopsies.

Background: Acral lesions may represent the best/only skin lesions to biopsy in patients suspected to have dermatomyositis (DM). However, histopathologic features of acral DM skin lesions are poorly characterized.

Methods: We reviewed 50 acral biopsies from 46 DM patients and assessed numerous histopathologic features.

An Analysis of the Prevalence and Trends in Drug-Related Lyrics on Twitter (X): Quantitative Approach.

Background: The pervasiveness of drug culture has become evident in popular music and social media. Previous research has examined drug abuse content in both social media and popular music; however, to our knowledge, the intersection of drug abuse content in these 2 domains has not been explored. To address the ongoing drug epidemic, we analyzed drug-related content on Twitter (subsequently rebranded X), with a specific focus on lyrics.

Adverse childhood experiences and defensive gun use: The indirect role of threat sensitivity and depressive symptoms.

Background/purpose: Adverse childhood experiences (ACEs) have been linked to various detrimental life outcomes, including an increase in threat sensitivity and depressive symptoms. Studies have also found an association between ACEs and firearm ownership. To date, no study has assessed whether ACEs have direct or indirect effects on defensive gun use (DGU) through these risk factors.

The community dynamic alterations mechanisms of traveling plastics in the Pearl River estuary with the salinity influence.

Most ocean plastics originate from terrestrial emissions, and the plastisphere on the plastics would alter during the traveling due to the significant differences in biological communities between freshwater and marine ecosystems. Microorganisms are influenced by the increasing salinity during traveling. To understand the contribution of plastic on the alteration in biological communities of plastisphere during traveling, this study investigated the alterations in microbial communities on plastics during the migration from freshwater to brackish water and saltwater.
