Primitive to visceral endoderm maturation is essential for mouse epiblast survival beyond implantation.

iScience

January 2025

Mammalian Embryo and Stem Cell Group, University of Cambridge, Department of Physiology, Development and Neuroscience, Downing Street, Cambridge CB2 3DY, UK.

The implantation of the mouse blastocyst initiates a complex sequence of tissue remodeling and cell differentiation events required for morphogenesis, during which the extraembryonic primitive endoderm transitions into the visceral endoderm. Through single-cell RNA sequencing of embryos at embryonic day 5.0, shortly after implantation, we reveal that this transition is driven by dynamic signaling activities, notably the upregulation of BMP signaling and a transient increase in Sox7 expression.

Engagement of adolescents with ADHD in a narrative-centered game-based behavior change environment to reduce alcohol use.

Front Educ (Lausanne)

January 2024

Division of Adolescent and Young Adult Medicine, Department of Pediatrics, University of California, San Francisco, San Francisco, CA, United States.

Background: Attention deficit hyperactivity disorder (ADHD) affects about 13% of adolescents and is associated with substance use-related morbidity and mortality. While evidence on effective interventions to reduce alcohol use among adolescents with ADHD is limited, parent-teen communication about alcohol use has been found to be protective. Other approaches, such as educational interventions, hold promise to reduce alcohol-related harms in adolescents with ADHD.

Background: In a recent randomized trial, six months of financial incentives contingent for recent alcohol abstinence led to lower levels of hazardous drinking, while incentives for recent isoniazid (INH) ingestion had no impact on INH adherence, during TB preventive therapy among persons with HIV (PWH). Whether the short-term incentives influence long-term alcohol use and HIV viral suppression post-intervention is unknown.

Methods: We analyzed twelve-month HIV viral suppression and alcohol use in the Drinkers' Intervention to Prevent Tuberculosis study, a randomized controlled trial among PWH with latent TB and unhealthy alcohol use in south-western Uganda.

A bibliometric and visualization analysis of electrochemical biosensors for early diagnosis of eye diseases.

Front Med (Lausanne)

January 2025

Department of Anatomy and Neurobiology, School of Basic Medical Sciences, Central South University, Changsha, China.

Electrochemical biosensors can provide an economical, accurate and rapid method for early screening of disease biomarkers in clinical medicine due to their high sensitivity, selectivity, portability, low cost and easy manufacturing, and multiplexing capability. Tear, a fluid naturally secreted by the human body, is not only easily accessible but also contains a great deal of biological information. However, no bibliometric studies focus on applying electrochemical sensors in tear/eye diseases.

Purpose: Speech-language pathologists (SLPs) are tasked with integrating the principles of evidence-based practice (EBP) to provide effective and efficient assessment and intervention services that best support clients and their families. As new research, technologies, and perspectives emerge, SLPs are required to adapt their clinical practices to meet these changes while maintaining high-quality evidence-based services. Through an illustrative case study, we aim to demonstrate the process of applying EBP principles - including research evidence, client and family perspectives, and clinical expertise - to a complexity-based speech sound intervention delivered via telepractice.

Degrons are short amino acid sequences that can facilitate the degradation of protein substrates. They can be classified as either ubiquitin-dependent or -independent based on their interactions with the ubiquitin proteasome system (UPS). These amino acid sequences are often found in exposed regions of proteins serving as either a tethering point for an interaction with an E3 ligase or initiating signaling for the direct degradation of the protein.

Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have shown benefits in improving cardiovascular (CV) outcomes in patients with heart failure (HF) and may mitigate symptom progression in myocardial infarction (MI). However, their effectiveness in patients with type 2 diabetes and MI undergoing percutaneous coronary intervention (PCI) is unclear.

Methods: To identify eligible studies, a comprehensive search of electronic databases, PubMed, Cochrane Library, Scopus and Embase, was conducted from inception until May 2024.

While investigating the potential for species to hybridize in the mixed populations of Point Sal and Burton Mesa in Santa Barbara County, California, we discovered that from the Nipomo Mesa (San Luis Obispo County), formerly considered a northern population of , are genetically and morphologically distinct. We name this new taxon after the ytt (Northern Chumash language) word for the Nipomo Mesa region. For morphological and molecular analyses, we sampled 54 plants, focusing on , , and from multiple species and comparative single species populations.

Tendon disease ranks among the leading reasons patients consult their general practitioners, comprising approximately one-third of musculoskeletal appointments. Magnetic resonance imaging (MRI) is regarded as the gold standard for assessing tendons. Due to their short transverse relaxation time (T2), Tendons show up as a signal void in conventional MRI scans, which employ sequences with echo times (TEs) around several milliseconds.

Extracting Thin Film Structures of Energy Materials Using Transformers.

ACS Phys Chem Au

January 2025

Neutron Scattering Division, Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831, United States.

Neutron-Transformer Reflectometry Advanced Computation Engine (), a neural network model using a transformer architecture, is introduced for neutron reflectometry data analysis. It offers fast, accurate initial parameter estimations and efficient refinements, improving efficiency and precision for real-time data analysis of lithium-mediated nitrogen reduction for electrochemical ammonia synthesis, with relevance to other chemical transformations and batteries. Despite limitations in generalizing across systems, it shows promises for the use of transformers as the basis for models that could accelerate traditional approaches to modeling reflectometry data.

Traditional fluorescence microscopy is blind to molecular microenvironment information that is present in fluorescence lifetime, which can be measured by fluorescence lifetime imaging microscopy (FLIM). However, most existing FLIM techniques are slow to acquire and process lifetime images, difficult to implement, and expensive. Here, we present instant FLIM, an analog signal processing method that allows real-time streaming of fluorescence intensity, lifetime, and phasor imaging data through simultaneous image acquisition and instantaneous data processing.

Background: Mosquito-borne diseases have a significant public health threat worldwide, with arboviruses accounting for a high proportion of infectious diseases and mortality annually. Brazil, in particular, has been suffering outbreaks of diseases transmitted by mosquito viruses, notably those of the genus, such as dengue, Zika, and chikungunya. Against this background, the São Paulo Zoo is an intriguing ecological niche to explore the virome of mosquitoes, potentially shedding light on the dynamics of arbovirus transmission within a confined setting.
