NumSimEX: A method using EXX hydrogen exchange mass spectrometry to map the energetics of protein folding landscapes.

Hydrogen exchange mass spectrometry (HXMS) is a powerful tool to understand protein folding pathways and energetics. However, HXMS experiments to date have used exchange conditions termed EX1 or EX2 which limit the information that can be gained compared to the more general EXX exchange regime. If EXX behavior could be understood and analyzed, a single HXMS timecourse on an intact protein could fully map its folding landscape without requiring denaturation.

Contemporary Normative Values for Five Common Static Standing Tasks on Firm and Compliant Floor Surfaces in Children Two to Thirteen Years.

Background/objectives: Static upright tasks, including standing unsupported (SU), eyes closed (SEC), feet together (SFT), tandem (TS), and single limb (SLS), are routinely examined in children and are included in many norm-referenced measures. Existing normative values for these standing tasks may not apply to contemporary children and have not been established across wide age ranges. The primary purpose of this study was to investigate developmental trajectories of and relationships between four static standing positions (SPs [SU, SFT, TS, SLS]) in children aged 2 through 13 years who are developing typically.

Efficacy of Household and Commercial Washing Agents in Removing the Pesticide Thiabendazole Residues from Fruits.

Pesticide residues on fruits pose a global food safety concern, emphasizing the need for effective and practical removal strategies to ensure safe consumption. This study investigates the efficacy of household ingredients (corn starch, all-purpose flour, rice flour and baking soda) and four commercial fresh produce wash products in eliminating a model pesticide thiabendazole with and without a model non-ionic surfactant Alligare 90 from postharvest fruits. Surface-enhanced Raman spectroscopy (SERS) was employed for the rapid, in situ quantification of residue removal on apple surfaces.

Gut microbiomes are largely unchanged when exposed to their amphibian host's latitudinally variable upper thermal limit.

Climate change will increase the frequency and severity of temperature extremes. Links between host thermal physiology and their gut microbiota suggest that organisms' responses to future climates may be mediated by their microbiomes, raising the question of how the thermal environment influences the microbiome itself. Vertebrate gut microbiomes influence the physiological plasticity of their hosts via effects on immunity, metabolism, and nutrient uptake.

Sensory reweighting for balance in people living with Parkinson's Disease: Postural adaptation, muscle co-contraction, and perceptual delays.

Background: Postural instability is common in people with Parkinson's Disease (PwPD), increasing their risk of injurious falls. Evidence suggests a sensory reweighting deficit in PwPD, along with compensatory muscle co-contraction in response to postural challenges. During balance tasks requiring sensory reweighting, older adults exhibit elevated postural sway and muscle co-contraction, as well as longer perceptual delays, compared to young adults.

Abdominal visceral and subcutaneous adipose tissue associations with postmenopausal breast cancer incidence.

Background: Obesity, classified by body mass index (BMI), is associated with higher postmenopausal breast cancer (BCa) risk. Yet, the associations between abdominal visceral (VAT) and subcutaneous adipose tissue (SAT) with BCa are unclear.

Methods: We assessed BCa associations with abdominal VAT and SAT in a prospective cohort of postmenopausal women without a history of cancer and with 27 years follow-up (N = 9950), during which all new cancers were adjudicated.

Where do "chemical imbalance" beliefs come from? Evaluating the impact of different sources.

Introduction: Although the etiology of depression is incredibly complex, the narrative that it is caused by a simple "chemical imbalance" persists in lay settings. We sought to understand where people are exposed to this explanation (i.e.

A beginner's guide to eye tracking for psycholinguistic studies of reading.

Eye tracking has been a popular methodology used to study the visual, cognitive, and linguistic processes underlying word recognition and sentence parsing during reading for several decades. However, the successful use of eye tracking requires researchers to make deliberate choices about how they apply this technique, and there is wide variability across labs and fields with respect to which choices are "standard." We aim to provide an easy-to-reference guideline that can help new researchers with their entrée into eye-tracking-while-reading research.

Cohort profile: the BangladEsh Longitudinal Investigation of Emerging Vascular and nonvascular Events (BELIEVE) cohort study.

Defects vibrations engineering for enhancing interfacial thermal transport in polymer composites.

To push upper boundaries of thermal conductivity in polymer composites, understanding of thermal transport mechanisms is crucial. Despite extensive simulations, systematic experimental investigation on thermal transport in polymer composites is limited. To better understand thermal transport processes, we design polymer composites with perfect fillers (graphite) and defective fillers (graphite oxide), using polyvinyl alcohol (PVA) as a matrix model.

The Influence of Migration Timing and Local Conditions on Reproductive Timing in Arctic-Breeding Birds.

For birds breeding in the Arctic, nest success is affected by the timing of nest initiation, which is partially determined by local conditions such as snow cover. However, conditions during the non-breeding season can carry over to affect the timing of breeding. We used tracking and breeding data from 248 individuals of 8 species and subspecies of Arctic-breeding shorebirds to estimate how the timing of nest initiation is related to local conditions like snowmelt phenology versus prior conditions, measured by the timing and speed of migration.

Structural and functional analysis of the Nipah virus polymerase complex.

Nipah virus (NiV) is a bat-borne, zoonotic RNA virus that is highly pathogenic in humans. The NiV polymerase, which mediates viral genome replication and mRNA transcription, is a promising drug target. We determined the cryoelectron microscopy (cryo-EM) structure of the NiV polymerase complex, comprising the large protein (L) and phosphoprotein (P), and performed structural, biophysical, and in-depth functional analyses of the NiV polymerase.

Parsing the existential isolation-outcome association into its within- and between-patient components in naturalistic psychotherapy.

Complementing the oft-studied construct of isolation, research has increasingly focused on existential isolation (EI), or the subjective feeling of separateness in one's experience. In the clinical realm, several studies have demonstrated that higher EI is associated with more severe mental health problems at a single cross-section of time. Moreover, one study showed that higher pretreatment EI predicted worse psychotherapy outcomes.

Shear-Stress Initiates Signal Two of NLRP3 Inflammasome Activation in LPS-Primed Macrophages through Piezo1.

The innate immune system is tightly regulated by a complex network of chemical signals triggered by pathogens, cellular damage, and environmental stimuli. While it is well-established that changes in the extracellular environment can significantly influence the immune response to pathogens and damage-associated molecules, there remains a limited understanding of how changes in environmental stimuli specifically impact the activation of the NLRP3 inflammasome, a key component of innate immunity. Here, we demonstrated how shear stress can act as Signal 2 in the NLRP3 inflammasome activation pathway by treating LPS-primed immortalized bone marrow-derived macrophages (iBMDMs) with several physiologically relevant magnitudes of shear stress to induce inflammasome activation.

A Friendlier "Kinda" Social System: Male Kinda Baboons Invest in Long-Term Social Bonds With Females.

Introduction: Enteric pathogens are a leading causes of diarrheal deaths in low-and middle-income countries. The Exposure Assessment of Infections in Rural Ethiopia (EXCAM) project, aims to identify potential sources of bacteria in the genus and, more generally, fecal contamination of infants during the first 1.5 years of life using as indicator.

Splenic Infarct: A Rare Complication of Infectious Mononucleosis in a Monospot-Negative Patient.

Splenic infarction with infectious mononucleosis (IM) caused by Epstein-Barr Virus (EBV) has been reported as a rare complication of IM. The monospot test, often used to diagnose EBV-related IM, may produce false-negative results, especially in atypical presentations or early stages of infection. This report describes the case of a monospot-negative patient who developed splenic infarction as a complication of IM.

Opportunities in Bottlebrush Block Copolymers for Advanced Materials.

Bottlebrush block copolymers (BBCPs) are a unique class of materials that contain a backbone with densely grafted and chemically distinct polymeric side chains. The nonlinear architecture of BBCPs provides numerous degrees of freedom in their preparation, including control over key parameters such as grafting density, side chain length, block arrangement, and overall molecular weight. This uniquely branched structure provides BBCPs with several important distinctions from their linear counterparts, including sterically induced side chain and backbone conformations, rapid and large self-assembled nanostructures, and reduced or eliminated entanglement effects (assuming sufficient grafting density and that the molecular weight of the side chains is below their respective entanglement molecular weight).

Plasmon-Enhanced Fluorescence Paper Lateral Flow Strip for Point-of-Care Testing of SARS-CoV-2 Antigens.

Currently commercial colorimetric paper lateral flow immunoassays exhibit insufficient limit of detection (LOD) and limited clinical sensitivity toward the detection of SARS-CoV-2 antigens, which causes a high false negative rate. To mitigate this issue, a new plasmon-enhanced fluorescence probe was developed for paper lateral flow strips (PLFSs). The probe is made of a sandwich-structured Ag-core@silica@dye@silica-shell nanoparticle in which fluorescent dyes are sandwiched between the plasmonic Ag core and the silica outer shell, and the separation distance between the Ag core and the dye molecules is controlled by the silica space layer.

Delamination of chick cephalic neural crest cells requires an MMP14-dependent downregulation of Cadherin-6B.

Matrix Metalloproteinases (MMPs) are known for their role in matrix remodeling via their catalytic activities in the extracellular space. Interestingly, these enzymes can also play less expected roles in cell survival, polarity and motility via other substrates (e.g.
