Comparison of transcriptomic profiles between intracellular and extracellular Bartonella henselae.

The Bartonella genus of bacteria encompasses ubiquitous species, some of which are pathogenic in humans and animals. Bartonella henselae, the causative agent of Cat Scratch disease, is responsible for a large portion of human Bartonella infections. These bacteria can grow outside of cells, replicate in erythrocytes and invade endothelial and monocytic cells.

Structure and mechanism of vitamin-K-dependent γ-glutamyl carboxylase.

γ-Glutamyl carboxylase (GGCX) is the sole identified enzyme that uses vitamin K (VK) as a cofactor in humans. This protein catalyses the oxidation of VK hydroquinone to convert specific glutamate residues to γ-carboxyglutamate residues in VK-dependent proteins (VDPs), which are involved in various essential biological processes and diseases. However, the working mechanism of GGCX remains unclear.

Three-dimensional diffractive acoustic tomography.

Acoustically probing biological tissues with light or sound, photoacoustic and ultrasound imaging can provide anatomical, functional, and/or molecular information at depths far beyond the optical diffusion limit. However, most photoacoustic and ultrasound imaging systems rely on linear-array transducers with elevational focusing and are limited to two-dimensional imaging with anisotropic resolutions. Here, we present three-dimensional diffractive acoustic tomography (3D-DAT), which uses an off-the-shelf linear-array transducer with single-slit acoustic diffraction.

Depression and Other Mood Disorders Across the Lifespan: Roles of the Obstetrician-Gynecologist.

Mood disorders such as depressive or bipolar disorders are more common among women. This review provides the fundamentals of diagnosing and treating mood disorders throughout a woman's lifespan. The etiology of mood disorders is not well-understood, but genetic, social, environmental, and neurobiologic factors play roles.

Characterization and Localization of Focal Atrial Tachycardia in Patients With Adult Congenital Heart Disease.

Background: In patients with structurally normal hearts, algorithms using surface electrocardiographic P-wave morphology are helpful to predict focal atrial tachycardia (FAT) location. However, these algorithms have not been formally assessed in patients with adult congenital heart disease (ACHD).

Objectives: This study sought to assess the efficacy of FAT-location prediction algorithms in an adult population of patients with ACHD.

Barriers and facilitators to global access to life-saving skills training: an international cross-sectional survey.

Introduction: Emergency care begins in the community, who are often the first on the scene. Where emergency care systems are nascent or absent, bystanders represent the only prehospital emergency care that victims might receive. It is important to equip bystanders through life-saving skills training (LST).

Using augmented reality to deliver cue exposure treatment for smoking cessation: App usability findings and protocol for a randomized controlled trial.

Background: Augmented Reality (AR) is a rapidly developing technology with potential utility for treating addictive behaviors, including tobacco smoking. AR inserts digital images into a natural real-time scene as viewed on a smartphone or other video devices. With respect to smoking cessation, AR can place virtual smoking cues (i.

The common murine retroviral integration site activating Hhex marks a distal regulatory enhancer co-opted in human Early T-cell precursor leukemia.

The Hhex gene encodes a transcription factor that is important for both embryonic and post-natal development, especially of hematopoietic tissues. Hhex is one of the most common sites of retroviral integration in mouse models. We found the most common integrations in AKXD (recombinant inbred strains) T-ALLs occur 57-61kb 3' of Hhex and activate Hhex gene expression.

Improved growth velocity using a new liquid human milk fortifier in Very Low Birth Weight infants: a multicenter, retrospective study.

Objective: To compare growth outcomes and tolerance among very low birth weight (VLBW) infants receiving a new, liquid human milk fortifier (LHMF-NEW) or a human milk fortifier-acidified liquid (HMF-AL).

Study Design: Retrospective, multicenter study of 515 VLBW infants in three regional NICUs. The primary objective was to compare growth velocity (g/kg/day) during fortification between groups by repeated measures regression.

Prenatal gene editing for neurodevelopmental diseases: Ethical considerations.

Neurodevelopmental diseases (NDDs) are notoriously difficult to treat because clinical symptoms stem from developmental processes that begin before birth. Prenatal gene editing could fill the treatment gap for NDDs by targeting and permanently correcting the genetic variants that underlie these pathogenic developmental processes. At the same time, there is a risk of unintended edits to the fetus or the pregnant person that could result in serious adverse consequences that are difficult, if not impossible, to undo.

Distribution and correlates of long-acting injectable antipsychotic use among community mental health center patients.

Although long-acting injectable antipsychotics (LAIs) are an important pharmaceutical option in the management of schizophrenia and related disorders, little is known about patient characteristics related to LAI use in real-world outpatient settings. We analyzed electronic medical records from 41,401 patients who received psychiatric services from one of 16 regional mental health centers operated by the South Carolina Department of Mental Health in 2022. We compared the use of first- and second-generation LAIs and oral antipsychotics by sociodemographic (age, gender, race/ethnicity, zip code, payment source) and clinical characteristics (psychiatric diagnoses, service use).

Copper-dependent halogenase catalyses unactivated C-H bond functionalization.

Carbon-hydrogen (C-H) bonds are the foundation of essentially every organic molecule, making them an ideal place to do chemical synthesis. The key challenge is achieving selectivity for one particular C(sp)-H bond. In recent years, metalloenzymes have been found to perform C(sp)-H bond functionalization.

Interrupting sitting with moderate-intensity physical activity breaks improves cognitive processing speed in adults with overweight and obesity: Findings from the SITLess pilot randomized crossover trial.

Introduction: Prolonged sitting can acutely reduce working memory (WM) in individuals with overweight and obesity (OW/OB) who show executive function deficits. Interrupting prolonged sitting with brief PA bouts may counter these effects. However, the benefits of such interventions on behavioral and neuroelectric indices of WM and whether neurocognitive responses are associated with postprandial glycemic responses in young and middle-aged adults with OW/OB remain unknown.

Chromosome length genome assembly of the stone marten (Martes foina, Mustelidae): a new view on one of the cornerstones in carnivore cytogenetics.

The stone marten (Martes foina) is an important species for cytogenetic studies in the order Carnivora. ZooFISH probes created from its chromosomes provided a strong and clean signal in chromosome painting experiments and were valuable for studying the evolution of carnivoran genome architecture. The research revealed that the stone marten chromosome set is similar to the presumed ancestral karyotype of the Carnivora, which added an additional value for the species.

Effects of volunteering on the psychological wellbeing of undergraduate college students.

The mental health of college students is declining at an alarming rate. Understanding behaviors linked to positive mental health outcomes and psychological wellbeing (PWB) are needed. The objective of this study was to determine the relationship between volunteering and PWB.

Measuring Intentional Communication in Infants at Elevated Likelihood of Autism: Validity, Reliability, and Responsiveness of a Novel Coding Scale.

Purpose: Intentional communication acts, or purposefully directed vocalizations and gestures, are particularly difficult for infants at elevated likelihood for eventual diagnosis of autism. The ability to measure and track intentional communication in infancy thus has the potential to aid early identification and intervention efforts. This study assesses the validity of a novel measure of intentional communication intended for use within semistructured caregiver-infant interactions.

Neonatal outcomes and resuscitation practices following the addition of heart rate-guidance to basic resuscitation.

Aim: To evaluate the impact of heart rate-guided basic resuscitation compared to Helping Babies Breathe on neonatal outcomes and resuscitation practices in the Democratic Republic of the Congo.

Methods: We conducted a pre-post clinical trial comparing heart rate-guided basic resuscitation to Helping Babies Breathe in three facilities, enrolling in-born neonates ≥28 weeks gestation. We collected observational data during a convenience sample of resuscitations and extracted clinical data from the medical record for all participants.

A simple tool to evaluate the effectiveness of HIV care for settings with gaps in data availability (ESTIHIV).

Many HIV clinics with poor IT-infrastructure are unable to report data on individuals in care with HIV, on antiretroviral treatment (ART) and virologically suppressed (VS), with the aim of monitoring the HIV Continuum of Care to estimate efficacy of HIV treatment programmes. We developed an estimation-tool, ESTIHIV, and determined the minimal data required for a random sample, to produce representative estimates, with a specified level of precision, of people with HIV on ART and VS. For proof of concept, 8852 HIV positive persons from seven clinics in seven different countries, with a follow-up visit during 2017, were included.

Genomic Analysis Reveals Racial and Age-Related Differences in the Somatic Landscape of Breast Cancer and the Association with Socioeconomic Factors.

Cancer genomics consortia have identified somatic drivers of breast cancer subtypes. However, these studies have predominantly included older, non-Black women, and the related socioeconomic status (SES) data is limited. Increased representation and depth of social data are crucial for understanding how health inequity is intertwined with somatic landscapes.

Hidradenitis Suppurativa Surgery Complication Rates Among Patients With Obesity or Diabetes or Who Smoke: A Review.

Importance: Surgery is frequently required for hidradenitis suppurativa (HS) treatment, but the impact of common comorbidities such as obesity, diabetes, and smoking on outcomes has been sparsely studied.

Observations: A total of 12 studies met final inclusion criteria for investigating complication rates associated with at least 1 comorbidity. Complication rates were associated with obesity in 3 of 10 studies.

Upper Limit on the Photoproduction Cross Section of the Spin-Exotic π_{1}(1600).

The spin-exotic hybrid meson π_{1}(1600) is predicted to have a large decay rate to the ωππ final state. Using 76.6  pb^{-1} of data collected with the GlueX detector, we measure the cross sections for the reactions γp→ωπ^{+}π^{-}p, γp→ωπ^{0}π^{0}p, and γp→ωπ^{-}π^{0}Δ^{++} in the range E_{γ}=8-10  GeV.
