Ligand guided in vivo crosslinking and affinity purification mass spectrometry for identifying membrane receptors of Tau.

Misfolded neurotoxic proteins, such as Tau protein, spread within the brain in many neurodegenerative diseases. Receptors play an important role in the recognition of spreading proteins for endocytosis. Blocking the receptors is essential to inhibit neurotoxic proteins spreading in the brain.

Acute effects of voluntary breathing patterns on postural control during walking.

Introduction: Breathing and postural control is reported to be both neuromuscularly and mechanically interdependent. To date, the effects of voluntary abdominal and thoracic breathing (VAB and VTB) on the EMG activity of muscles involved in both respiratory and postural functions, as well as gait biomechanics related to these breathing patterns, have not been investigated in young, healthy adults. The aim of the study was to evaluate the EMG responses of neck and trunk muscles, as well as the kinematic, stability, and kinetic parameters of gait induced by VAB and VTB compared to involuntary breathing (INB).

Concepts of Suffering at the End of Life Amongst Emergency, Palliative Care and Geriatric Medicine Physicians in Malaysia.

Background: Palliative Care, Geriatrics and Emergency physicians are exposed to death, terminally ill patients and distress of patients and their families. As physicians bear witness to patients' suffering, they are vulnerable to the costs of caring-the emotional distress associated with providing compassionate and empathetic care to patients. If left unattended, this may culminate in burnout and compromise professional identity.

First-Line Mobocertinib Versus Platinum-Based Chemotherapy in Patients With Exon 20 Insertion-Positive Metastatic Non-Small Cell Lung Cancer in the Phase III EXCLAIM-2 Trial.

Purpose: Mobocertinib is an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor that targets exon 20 insertion (ex20ins) mutations in non-small cell lung cancer (NSCLC). This open-label, phase III trial (EXCLAIM-2: ClinicalTrials.gov identifier: NCT04129502) compared mobocertinib versus platinum-based chemotherapy as first-line treatment of ex20ins+ advanced/metastatic NSCLC.

Century-long West Antarctic snow accumulation changes induced by tropical teleconnections.

Ice core measurements reveal dipole-like snow accumulation trends over West Antarctica throughout the 20th century, with an increase of >2000 billion metric tons over the Antarctic Peninsula and Ellsworth Land but a decrease of ~500 billion metric tons over Marie Byrd Land. Although atmospheric teleconnections were frequently revealed, linking variability between tropics and higher latitudes on interannual and decadal timescales, centennial-scale teleconnection is absent from literature. Here, using statistical analysis and numerical experiments, we reveal that changes of tropical oceans throughout the 20th century drive the long-term Antarctic snowfall trend.

Measuring STEM Instructors' Learning of and Growth in Inclusive Teaching: Development and Evaluation of the STEM Faculty Inclusive Teaching Survey (FITS).

There is a growing emphasis for professional development programs that teach instructors about inclusive Science, Technology, Engineering, and Mathematics (STEM) practices and the impact of instructor and student identities on these practices. As instructors implement these practices, there is a need for instructors, departments, and faculty developers to measure instructor progress and to help identify next steps in improving inclusive STEM teaching. This study describes the development of the Faculty Inclusive Teaching Survey (FITS) using scale-development theory, frameworks using Clarke and Hollingsworth's interconnected model of professional growth and Dewsbury's Deep Teaching model, and higher-education STEM, Diversity, Equity, and Inclusion, and professional development literature.

Reduced SARS-CoV-2 Infection Rates in Lab Workers Conducting Nucleic Acid Testing: Controlling for the Healthy Worker Effect.

Background: During the COVID-19 outbreak in December 2022 in China, some laboratory workers in SARS-CoV-2 nucleic acid testing (NAT) laboratories remained uninfected.

Objectives: To evaluate if the incidence of SARS-CoV-2 infection was reduced in laboratory workers who performed SARS-CoV-2 NAT, and whether this reduction resulted from the healthy worker effect.

Methods: This retrospective cohort study included 423 laboratory workers from 14 SARS-CoV-2 NAT laboratories in Xiamen, China.

2-dodecyl-6-methoxycyclohexa-2,5-diene-1,4-dione protects against MPP-induced neurotoxicity by ameliorating oxidative stress, apoptosis and autophagy in SH-SY5Y cells.

2-dodecyl-6-methoxycyclohexa-2,5-diene-1,4-dione (DMDD) is a cyclohexanedione compound extracted from the roots of Averrhoa carambola L. Several studies have documented its beneficial effects on diabetes, Alzheimer's disease, and cancer. However, its potential neuroprotective effects on Parkinson's disease (PD) have not yet been explored.

SHP2 promotes the epithelial-mesenchymal transition in triple negative breast cancer cells by regulating β-catenin.

Purpose: Growing evidence suggests that the tyrosine phosphatase SHP2 is pivotal for tumor progression. Triple-negative breast cancer (TNBC) is the most lethal subtype of breast cancer, characterized by its high recurrence rate, aggressive metastasis, and resistance to chemotherapy. Understanding the mechanisms of tumorigenesis and the underlying molecular pathways in TNBC could aid in identifying new therapeutic targets.

Characterization of the host specificity of the SH3 cell wall binding domain of the staphylococcal phage 88 endolysin.

Bacteriophages produce endolysins at the end of the lytic cycle, which are crucial for lysing the host cells and releasing virion progeny. This lytic feature allows endolysins to act as effective antimicrobial alternatives when applied exogenously. Staphylococcal endolysins typically possess a modular structure with one or two enzymatically active N-terminal domains (EADs) and a C-terminal cell wall binding domain (CBD).

LPCAT1, the Enzyme Responsible for Converting LPC to PC, Promotes OPC Differentiation In Vitro.

Myelin is the key structure for high-speed information transmission and is formed by oligodendrocytes (OLs) which are differentiated from oligodendrocyte precursor cells (OPCs) in the central nervous system. Lipid is the main component of myelin and the role of lipid metabolism-related molecules in myelination attach increasing attention. Lysophosphatidylcholine acyltransferase 1 (LPCAT1) mediates the conversion of lysophosphatidylcholine (LPC) to phosphatidylcholine (PC), and its role in myelination draws our interest as LPC is a classical demyelination inducer and PC is a major component of myelin.

An evolved, orthogonal ssDNA generator for targeted hypermutation of multiple genomic loci.

Achieving targeted hypermutation of specific genomic sequences without affecting other regions remains a key challenge in continuous evolution. To address this, we evolved a T7 RNA polymerase (RNAP) mutant that synthesizes single-stranded DNA (ssDNA) instead of RNA in vivo, while still exclusively recognizing the T7 promoter. By increasing the error rate of the T7 RNAP mutant, it generates mutated ssDNA that recombines with homologous sequences in the genome, leading to targeted genomic hypermutation.

Electronic cigarettes for smoking cessation.

Background: Electronic cigarettes (ECs) are handheld electronic vaping devices that produce an aerosol by heating an e-liquid. People who smoke, healthcare providers, and regulators want to know if ECs can help people quit smoking, and if they are safe to use for this purpose. This is a review update conducted as part of a living systematic review.

Interventions to reduce non-prescription antimicrobial sales in community pharmacies.

Background: Antimicrobial resistance (AMR) is a major global health concern. One of the most important causes of AMR is the excessive and inappropriate use of antimicrobial drugs in healthcare and community settings. Most countries have policies that require antimicrobial drugs to be obtained from a pharmacy by prescription.

The Picture of Health: Seeing the Health of the Chronically Challenged Through Van Gogh's Sunflowers as a Needed Revision of the Clinical Perspective.

This article identifies and offers a response to several problems that affect the quality of both clinical education and health care services. These matters are: that in clinical training and practice, health, as lived by patients (persons), is not properly considered, and is equated reductively with treating diseases/disorders; that health is seen through disease, and as restricted to a single model defined by an organism's meeting (or being returned to) biochemical or functional standards; that intellectual assumptions instilled in schools of Medicine and Psychology about realities pertaining to healthcare determine an understanding of chronic illness or life with chronic challenges focused on impairment and suffering, and not on the fuller experience of living with illness, disability or neuropsychological challenges that patients have as persons; that arts-based education reflects the same focus in understanding 'illness', and thus neglects giving attention to the creation of personal health states of those living with challenging or debilitating long-term conditions; that, consequently, the arts are instrumentalized to serve these predefined educational purposes, rather than allowed to inform clinical training through that which is intrinsic or more specific to them. As a way out of these limitations and as an illustration of how things could be done differently, Vincent Van Gogh's paintings of the Sunflowers are used as visual inspiration for how we could change the way we see, and construct new mental representations of 'health', 'chronic illness' or 'chronic challenges', 'patient as person' or even 'person as non-patient', 'the clinician's role' and 'the identity of clinical practice'.

Characterization of multiple binding sites on microtubule associated protein 2c recognized by dimeric and monomeric 14-3-3ζ.

Microtubule associated protein 2 (MAP2) interacts with the regulatory protein 14-3-3ζ in a cAMP-dependent protein kinase (PKA) phosphorylation dependent manner. Using selective phosphorylation, calorimetry, nuclear magnetic resonance, chemical crosslinking, and X-ray crystallography, we characterized interactions of 14-3-3ζ with various binding regions of MAP2c. Although PKA phosphorylation increases the affinity of MAP2c for 14-3-3ζ in the proline rich region and C-terminal domain, unphosphorylated MAP2c also binds the dimeric 14-3-3ζ via its microtubule binding domain and variable central domain.

Cross-cultural validation of plasma p-tau217 and p-tau181 as precision biomarkers for amyloid PET positivity: An East Asian study in Taiwan and Korea.

Introduction: Plasma phosphorylated tau (p-tau) biomarkers have improved Alzheimer's disease (AD) diagnosis, but data from diverse Asian populations are limited. This study evaluated plasma p-tau217 and p-tau181 levels in Korean and Taiwanese populations.

Methods: All participants (n = 270) underwent amyloid positron emission tomography (PET) and blood tests.

Surface immobilization of single atoms on heteroatom-doped carbon nanospheres through phenolic-mediated interfacial anchoring for highly efficient biocatalysis.

Single-atom catalysts (SACs) dispersed on support materials exhibit exceptional catalytic properties that can be fine-tuned through interactions between the single atoms and the support. However, selectively controlling the spatial location of single metal atoms while simultaneously harmonizing their coordination environment remains a significant challenge. Here, we present a phenolic-mediated interfacial anchoring (PIA) strategy to prepare SACs with Fe single atoms anchored on the surface of heteroatom-doped carbon nanospheres.

Comparing parboiling and milling for selenium-enriched rice (): Differences in selenium speciation, texture, microstructure, and sensory.

Parboiled rice can effectively retain Se during milling. In this study, Se-enriched rice grains were sprayed with three different concentrations of bioSeNPs fertilizer on the leaves at heading stage and then processed into parboiled and milled rice. The aim was to investigate the effects of parboiling on Se speciation, texture, microstructure, taste, and flavor of cooked rice.

Health utility value of overactive bladder in Japanese older adults.

Objectives: To determine the health utility values (HUVs) of overactive bladder (OAB), defined as urinary urgency, usually accompanied by urinary daytime or nocturnal frequency, with or without urinary incontinence, among adults aged ≥65 years and to assess the HUV decrements (disutilities) of OAB according to its severity.

Methods: This cross-sectional Internet-based study was conducted between 2 and 9 November 2023, with quota sampling with equal probability for each sex and age group (age 65-74 years and ≥75 years). OAB was defined as an urgency score of ≥2 points and a total score of ≥3 points based on the Overactive Bladder Symptom Score.

The primiparous IgA and IL-5 colostrum concentration based on maternal factor: corroborate the inflammation pathways to IgA colostrum synthesis.

Background: Immunoglobulin A (IgA) plays a crucial role in the maturation the neonatal mucosal barrier. The accumulation of IgA antibody-secreting cells (ASCs) in the lactating mammary gland facilitates the secretion of IgA antibodies into milk, which are then passively to the suckling newborn, providing transient immune protection against gastrointestinal pathogens. Physiologically, full-term infants are unable to produce IgA, required for mucosal barrier maturation for at least 10 days after birth.
