Infants with Excessive Weight Gain while Exclusively Breastfeeding: Follow-Up at 36 Months.

Rapid weight gain in infancy is associated with an increased risk of later adiposity. Very rarely, however, exclusively breastfed infants experience excessive weight gain (EWG) during the period of exclusive breastfeeding (EBF) when breast milk is the only source of nutrition. We investigated growth and body composition at 36 months in children experiencing EWG during EBF.

Differences in maternal diet fiber content influence patterns of gene expression and chromatin accessibility in fetuses and piglets.

This study investigates the impact of maternal gestation diets with varying fiber contents on gene expression and chromatin accessibility in fetuses and piglets fed a low fiber diet post weaning. High-fiber maternal diets, enriched with sugar beet pulp or pea internal fiber, were compared to a low-fiber maternal diet to evaluate their effects on liver and muscle tissues. The findings demonstrate that maternal high-fiber diets significantly alter chromatin accessibility, predicted transcription factor activity and transcriptional landscape in both fetuses and piglets.

A synthetic cyclic peptide for promoting antigen presentation and immune activation.

Cyclic peptides are often used as scaffolds for the multivalent presentation of drug molecules due to their structural stability and constrained conformation. We identified a cyclic deca-peptide incorporating lipoamino acids for delivering T helper and B cell epitopes against group A Streptococcus (GAS), eliciting robust humoral immune responses. In this study, we assessed the function-immunogenicity relationship of the multi-component vaccine candidate (referred to as VC-13) to elucidate a mechanism of action.

Compressive electron backscatter diffraction imaging.

Electron backscatter diffraction (EBSD) has developed over the last few decades into a valuable crystallographic characterisation method for a wide range of sample types. Despite these advances, issues such as the complexity of sample preparation, relatively slow acquisition, and damage in beam-sensitive samples, still limit the quantity and quality of interpretable data that can be obtained. To mitigate these issues, here we propose a method based on the subsampling of probe positions and subsequent reconstruction of an incomplete data set.

Mechanism-guided engineering of a minimal biological particle for genome editing.

The widespread application of genome editing to treat and cure disease requires the delivery of genome editors into the nucleus of target cells. Enveloped delivery vehicles (EDVs) are engineered virally derived particles capable of packaging and delivering CRISPR-Cas9 ribonucleoproteins (RNPs). However, the presence of lentiviral genome encapsulation and replication proteins in EDVs has obscured the underlying delivery mechanism and precluded particle optimization.

Ultrasensitive detection of intact SARS-CoV-2 particles in complex biofluids using microfluidic affinity capture.

Measuring virus in biofluids is complicated by confounding biomolecules coisolated with viral nucleic acids. To address this, we developed an affinity-based microfluidic device for specific capture of intact severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Our approach used an engineered angiotensin-converting enzyme 2 to capture intact virus from plasma and other complex biofluids.

Aneurysm dome and vessel pressure measurements with coiling, stent assisted coiling and flow diversion.

Background: Variability in long-term endovascular treatment outcomes for intracranial aneurysms has prompted questions regarding the effects of these treatments on aneurysm hemodynamics. Endovascular techniques disrupt aneurysmal blood flow and shear, but their influence on intra-aneurysmal pressure remains unclear. A better understanding of aneurysm pressure effects may aid in predicting outcomes and guiding treatment decisions.

Bernard Greenberg: a legacy in medical, veterinary, and forensic entomology.

Bernard Greenberg was a ground-breaking scientist in the worlds of medical-veterinary and forensic entomology, studying the ability of flies to serve as a vector of human and other vertebrate pathogens. His work also extended beyond these topics, creating key studies on flies and their associated microbial ecology. These efforts led to numerous research publications and two books on flies and their associated microorganisms.

Factors Affecting Chlorinated Product Formation from Sodium Hypochlorite Bleach and Limonene Reactions in the Gas Phase.

During use of sodium hypochlorite bleach, gas-phase hypochlorous acid (HOCl) and chlorine (Cl) are released, which can react with organic compounds present in indoor air. Reactivity between HOCl/Cl and limonene, a common constituent of indoor air, has been observed. The purpose of this study was to characterize the chemical species generated from gas-phase reactions between HOCl/Cl and limonene.

Reconstitution of human DNA licensing and the structural and functional analysis of key intermediates.

Human DNA licensing initiates replication fork assembly and DNA replication. This reaction promotes the loading of the hMCM2-7 complex on DNA, which represents the core of the replicative helicase that unwinds DNA during S-phase. Here, we report the reconstitution of human DNA licensing using purified proteins.

A Randomized, Blinded, Vehicle-Controlled Dose-Ranging Study to Evaluate and Characterize Remdesivir Efficacy Against Ebola Virus in Rhesus Macaques.

Ebola virus (EBOV) causes severe disease in humans, with mortality as high as 90%. The small-molecule antiviral drug remdesivir (RDV) has demonstrated a survival benefit in EBOV-exposed rhesus macaques. Here, we characterize the efficacy of multiple intravenous RDV dosing regimens on survival of rhesus macaques 42 days after intramuscular EBOV exposure.

Methods And Materials: The optical properties of the translucency parameter (TP) and opalescence parameter (OP) were obtained with a dental spectrophotometer.

Beyond Traditional Body Composition Metrics: Load-Capacity Indices Emerge as Predictors of Cardiometabolic Outcomes-A Systematic Review and Meta-Analysis.

The adaptive and independent interrelationships between different body composition components have been identified as crucial determinants of disease risk. On the basis of this concept, the load-capacity model of body composition, which utilizes measurements obtained through nonanthropometric techniques such as dual-energy X-ray absorptiometry, was proposed. This model is typically operationalized as the ratio of metabolic load (adipose mass) to metabolic capacity (lean mass).

National extension workshop: Connecting learners and educators to broaden reach and maximize impact in the 21st century.

Disseminating training nationwide through the Cooperative Extension Service, particularly as global demand for poultry products continues to increase, is critical for sustainable poultry production. Increasing urbanization, globalization of the poultry industry, consumer interest in animal welfare and labor shortages present opportunities for Extension professionals to engage diverse audiences and increase agricultural literacy. As part of the Poultry Science Association's 2024 National Extension Workshop, we presented examples of initiatives aimed at connecting educators, teachers and learners to address some of the pressing issues facing the poultry industry.

HIPPO artificial intelligence: Correlating automated radiographic femoroacetabular measurements with patient-reported outcomes in developmental hip dysplasia.

Background: Hip dysplasia (HD) is characterized by insufficient acetabular coverage of the femoral head, leading to a predisposition for osteoarthritis. While radiographic measurements such as the lateral center edge angle (LCEA) and Tönnis angle are essential in evaluating HD severity, patient-reported outcome measures (PROMs) offer insights into the subjective health impact on patients.

Aim: To investigate the correlations between machine-learning automated and manual radiographic measurements of HD and PROMs with the hypothesis that artificial intelligence (AI)-generated HD measurements indicating less severe dysplasia correlate with better PROMs.

Excision of an intrascleral cyst guided by anterior segment optical coherence tomography.

A 4-year-old girl presented with an enlarging, congenital, intrascleral cyst of the left eye. Intraoperative anterior segment optical coherence tomography was used to visualize and to assess the extent of the cyst, facilitating safe excision. The cyst was completely removed, and the defect was covered with an amniotic membrane graft, with a good outcome.

Reverse-engineering the Venus figurines: An eco-life-course hypothesis for the aetiology of obesity in the Palaeolithic.

Evolutionary perspectives on obesity have been dominated by genetic frameworks, but plastic responses are also central to its aetiology. While often considered a relatively modern phenomenon, obesity was recorded during the Palaeolithic through small statuettes of the female form (Venus figurines). Even if the phenotype was rare, these statuettes indicate that some women achieved large body sizes during the last glacial maximum, a period of nutritional stress.

Associations of body composition at birth and accretion from 0 to 5 years with kidney function and volume at the 10-year follow-up: the Ethiopian Infant Anthropometry and Body Composition birth cohort.

Background: Fat mass (FM) and fat-free mass (FFM) in early life are associated with later obesity and cardiometabolic disease.

Objectives: This study aimed to assess the associations of FM and FFM at birth and conditional FM and FFM accretion from 0 to 5 y with kidney outcomes at the 10-y follow-up.

Methods: The Ethiopian Infant Anthropometry and Body Composition birth cohort included term infants born in Jimma town, with a birth weight ≥1500 g, and having no congenital malformations.

Associations of early childhood exposure to severe acute malnutrition and recovery with cardiometabolic risk markers in later childhood: 5-year prospective matched cohort study in Ethiopia.

Background: Impaired fetal and accelerated postnatal growth are associated with cardiometabolic disease. Few studies investigated how recovery from severe acute malnutrition (SAM) is associated with childhood cardiometabolic risk.

Objectives: We evaluated cardiometabolic risk in children with SAM treated through community-based management, relative to controls, 5-y postrecovery.

Deriving Human Intestinal Organoids with Functional Tissue-Resident Macrophages All From Pluripotent Stem Cells.

Background & Aims: Organs of the gastrointestinal tract contain tissue-resident immune cells that function during tissue development, homeostasis, and disease. However, most published human organoid model systems lack resident immune cells, thus limiting their potential as disease avatars. For example, human intestinal organoids (HIOs) derived from pluripotent stem cells contain epithelial and various mesenchymal cell types but lack immune cells.

infection on European farms is associated with an altered tonsil microbiome and resistome.

is a Gram-positive opportunistic pathogen causing systemic disease in piglets around weaning age. The factors predisposing to disease are not known. We hypothesized that the tonsillar microbiota might influence disease risk via colonization resistance and/or co-infections.
