A molecular chemodosimeter to probe "closed shell" ions in kidney cells.

Two quinidine-functionalized coumarin molecular probes have been synthesized and have been found to bind metal cations (Cd, Co, Cu, Fe, Hg, Ni, and Zn) with high affinity in organic-aqueous media (DMSO-HEPES). The chemodosimeters coordinate with the Zn ions in a two-to-one ratio (molecular probe : Zn) with a log  of 10.0 M.

Mapping PTSD, depression, and anxiety: A network analysis of co-occurring symptoms in treatment-seeking first responders.

First responders are at high risk for a range of co-occurring mental health conditions due to their repeated exposure to traumatic events. When first responders present for treatment, their complex presentation of symptoms including posttraumatic stress disorder (PTSD), depression, and generalized anxiety disorder (GAD) can prove challenging to differentiate for clinical purposes. Network analysis provides a means to identify the nuanced associations between the symptoms of these conditions and to identify groups of related symptoms.

Long-term ecological research in freshwaters enabled by regional biodiversity collections, stable isotope analysis, and environmental informatics.

Biodiversity collections are experiencing a renaissance fueled by the intersection of informatics, emerging technologies, and the extended use and interpretation of specimens and archived databases. In this article, we explore the potential for transformative research in ecology integrating biodiversity collections, stable isotope analysis (SIA), and environmental informatics. Like genomic DNA, SIA provides a common currency interpreted in the context of biogeochemical principles.

A super-massive Neptune-sized planet.

Neptune-sized planets exhibit a wide range of compositions and densities, depending on factors related to their formation and evolution history, such as the distance from their host stars and atmospheric escape processes. They can vary from relatively low-density planets with thick hydrogen-helium atmospheres to higher-density planets with a substantial amount of water or a rocky interior with a thinner atmosphere, such as HD 95338 b (ref. ), TOI-849 b (ref.

Palladium and Iron Cocatalyzed Aerobic Alkene Aminoboration.

Aminoboration of simple alkenes with nitrogen nucleophiles remains an unsolved problem in synthetic chemistry; this transformation can be catalyzed by palladium aminopalladation followed by transmetalation with a diboron reagent. However, this catalytic process faces inherent challenges with instability of the alkylpalladium(II) intermediate toward β-hydride elimination. Herein, we report a palladium/iron cocatalyzed aminoboration, which enables this transformation.

Effects of anthropogenic light on anuran calling site.

The natural environment can be negatively impacted by a variety of human activities, including the production of artificial light at night. Recent studies suggest that pollution from anthropogenic light alters animal behavior. Despite being highly nocturnal, little attention has been given to anurans and the effects artificial light at night has on their behavior.

Analysis of Serum Ferritin Levels in a Group of Elite Ballet Dancers.

Introduction: Iron plays a significant role in energy production. However, it is not uncommon for athletes to be diagnosed with iron deficiency (ID), suggesting a correlation between performance and iron regulation. As a result, the International Olympic Committee has recommended iron screenings during health evaluations for elite athletes.

Validation of the PCL-5, PHQ-9, and GAD-7 in a Sample of Veterans.

Objective: Veterans can present at nongovernment (Department of Defense, Department of Veterans Affairs) mental health agencies with complex symptom constellations that frequently include posttraumatic stress disorder, depression, and generalized anxiety. To date, no veteran study has validated these measures on a treatment-seeking sample of veterans outside the DoD and VA.

Methods: We used a treatment-seeking sample of veterans ( N = 493) to validate measures that assess these constructs (PTSD Checklist 5, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7).

Post hoc experimental designs improve genetic trial analyses: A case study of cherrybark oak (Quercus pagoda Raf.) genetic evaluation in the western Gulf region, USA.

Oaks (Quercus spp.) are widespread hardwood trees in the Northern Hemisphere and of high ecological, economic, and social values. Optimal experimental design of genetic trials is essential for accurate estimates of genetic parameters and improving the genetic merit of breeding stock.

A deeper understanding of noise effects on cetaceans.

Recent research with cetaceans under human care is illuminating just how dolphins are affected by human-made noise both in terms of their ability to cooperate as well as their ability to habituate to such noise. This research is providing granular detail to regulators assessing the problems associated with anthropogenic effects and is highlighting a role for behavior/cognition research in conservation.

Transcriptomic and metabolomic analyses unveil the growth advantage mechanism conferred by heterosis of Michelia 'Zhongshanhanxiao'.

Michelia compressa (Maxim.) Sarg. is one of the important timber trees in Taiwan province, P.

Validation of the PCL-5, PHQ-9, and GAD-7 in a Sample of First Responders.

Objective: First responders (FRs) commonly present for treatment with complex symptom constellations that frequently include posttraumatic stress disorder, depression, and generalized anxiety. To date, no FR study has validated these measures on a treatment-seeking sample.

Methods: Confirmatory factor analysis was utilized to validate measures that assess these constructs (Posttraumatic Stress Disorder Checklist for DSM-5, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7) on a treatment-seeking sample of FRs ( N = 390).

Effects of Highly Cushioned and Resilient Racing Shoes on Running Economy at Slower Running Speeds.

Purpose: The Nike Vaporfly line of running shoes improves running economy by ∼2.7% to 4.2% at running speeds of 13 to 18 km·h-1.

Grafting Causes Physiological Changes and Promotes Adventitious Root Formation in Rejuvenated Soft Shoots of 'Zhongshanshan'.

'Zhongshanshan' has been widely used as a timber tree in river network areas and coastal regions and is mainly propagated by cuttings. However, when trees age, their capacity to form adventitious roots becomes weaker. We successfully enhanced the rooting ability of shoots in 'Zhongshanshan 302' by their rejuvenation based on grafting.

Afforestation of Hybrid Zhongshanshan Influences Soil Bacterial Community Structure by Altering Soil Properties in the Yangtze River Basin, China.

hybrid Zhongshanshan has been widely planted in the Yangtze River Basin (YRB) for soil and carbon conservation, with quantities over 50 million. The objective of this study was to determine how . hybrid Zhongshanshan plantations affected soil physicochemical properties and bacterial community structure in the YRB, and to examine the consistency of changes by afforestation.

Association between Fecal Microbiota, SCFA, Gut Integrity Markers and Depressive Symptoms in Patients Treated in the Past with Bariatric Surgery-The Cross-Sectional Study.

(1) Background: Depressive symptoms often appear after surgical treatment. (2) Methods: We involved 41 adults who underwent bariatric surgery a minimum of 6 months before the study and had the Beck scale ≥12. We analysed patients' mental state, gut barrier markers, faecal short chain fatty acids, and microbiota.

Beyond Chaperoning: UCS Proteins Emerge as Regulators of Myosin-Mediated Cellular Processes.

The UCS (UNC-45/CRO1/She4p) family of proteins has emerged as chaperones specific for the folding, assembly, and function of myosin. UCS proteins participate in various myosin-dependent cellular processes including myofibril organization and muscle functions, cell differentiation, striated muscle development, cytokinesis, and endocytosis. Mutations in the genes that code for UCS proteins cause serious defects in myosin-dependent cellular processes.

Identification and characterization of proteins that form the inner core Ixodes scapularis tick attachment cement layer.

Ixodes scapularis long-term blood feeding behavior is facilitated by a tick secreted bio adhesive (tick cement) that attaches tick mouthparts to skin tissue and prevents the host from dislodging the attached tick. Understanding tick cement formation is highly sought after as its disruption will prevent tick feeding. This study describes proteins that form the inner core layer of I.
