Since early 2022 highly pathogenic avian influenza (HPAI) H5N1 virus infections have been reported in wild aquatic birds and poultry throughout the United States (US) with spillover into several mammalian species. In March 2024, HPAIV H5N1 clade 2.3.

The impact of highly effective modulator therapy on sinusitis and dysosmia in young children with cystic fibrosis: a prospective study protocol.

Background: Chronic rhinosinusitis (CRS) and olfactory dysfunction (OD) are prevalent disease complications in people with cystic fibrosis. These understudied comorbidities significantly impact quality of life. The impact of highly effective modulator therapy (HEMT) in young children with cystic fibrosis (YCwCF) on these disease complications is unknown.

Socioeconomic, Race-Ethnicity, Household, and Infrastructure Disparities of Hematologic Cancer Outcomes in the US.

Although social determinants of health (SDoH) investigations have shown limited analyses of socioeconomic and race-ethnic status on certain hematologic malignancies, the impact of factors beyond those across a fuller scope of hematologic cancers remains unknown. The Social Vulnerability Index (SVI), a tool for assessing varied US-census derived sociodemographic factors, allows the specific quantification of SDoH in dynamic, regional contexts for their associations with hematologic-malignancy inequities. To assess the summative influence of varied SDoH-factors on hematologic malignancy outcomes and discern which SDoH-factors contributed the largest associations towards disparities 796,005 adults with hematologic malignancies between 1975-2017 were identified for this retrospective cohort study.

Construction and Characterization of MoClo-Compatible Vectors for Modular Protein Expression in .

Cloning methods are fundamental to synthetic biology research. The capability to generate custom DNA constructs exhibiting predictable protein expression levels is crucial to the engineering of biology. Golden Gate cloning, a modular cloning (MoClo) technique, enables rapid and reliable one-pot assembly of genetic parts.

A precision oncology-focused deep learning framework for personalized selection of cancer therapy.

Precision oncology matches tumors to targeted therapies based on the presence of actionable molecular alterations. However, most tumors lack actionable alterations, restricting treatment options to cytotoxic chemotherapies for which few data-driven prioritization strategies currently exist. Here, we report an integrated computational/experimental treatment selection approach applicable for both chemotherapies and targeted agents irrespective of actionable alterations.

How to use the Artisse intrasaccular device.

Intrasaccular flow disruption has become established for the treatment of wide necked and bifurcation aneurysms. The most successful current devices are the WEB (Microvention) and Contour (Stryker). The Artisse (Medtronic) is a novel intrasaccular device designed to treat a variety of aneurysm morphologies.

Risk of venous thromboembolic complications in pregnant trauma patients: A matched cohort study.

Background: Trauma and pregnancy are both risk factors for venous thromboembolism (VTE). We hypothesized that pregnant blunt trauma patients would have a higher incidence of VTE complications compared with matched nonpregnant females.

Methods: We conducted a retrospective cohort study using National Trauma Data Bank data from 2017 to 2022.

Eruptive Insect Outbreaks from Endemic Populations Under Climate Change.

Insects, especially forest pests, are frequently characterized by eruptive dynamics. These types of species can stay at low, endemic population densities for extended periods of time before erupting in large-scale outbreaks. We here present a mechanistic model of these dynamics for mountain pine beetle.

Patient-Derived Xenografts of Triple-Negative Breast Cancer Enable Deconvolution and Prediction of Chemotherapy Responses.

Unlabelled: Combination chemotherapy remains essential for clinical management of triple-negative breast cancer (TNBC). Consequently, responses to multiple single agents cannot be delineated at the single patient level, even though some patients might not require all drugs in the combination. Herein, we conduct multi-omic analyses of orthotopic TNBC patient-derived xenografts (PDXs) treated with single agent carboplatin, docetaxel, or the combination.

Environmental Enrichment Attenuates Repetitive Behavior and Alters the Functional Connectivity of Pain and Sensory Pathways in C58 Mice.

Restricted repetitive behaviors (RRB) encompass a variety of inflexible behaviors, which are diagnostic for autism spectrum disorder (ASD). Despite being requisite diagnostic criteria, the neurocircuitry of these behaviors remains poorly understood, limiting treatment development. Studies in translational animal models show environmental enrichment (EE) reduces the expression of RRB, although the underlying mechanisms are largely unknown.

OpenFlume: An accessible and reproducible benchtop flume for research and education.

Open-channel flumes are an important tool in fluid mechanics research and education. However, the few commercially available small-scale flumes are generally expensive and lack complete characterization. In this work, we present an open-source, low-cost, modular benchtop laboratory flume that is designed to be accessible and reproducible.

Uncovering the complexity of structural variants in four individuals with autism spectrum disorder.

Autism spectrum disorder (ASD) is an increasingly recognized childhood developmental disorder. Despite extensive study, causal variants and molecular diagnosis remain elusive. There is both heterogeneity of the phenotype, as well as the genetic landscape associated with phenotype, which includes both inherited and de novo mutations.

Risk Factors for Consensual and Coercive Sexual Hookup Behaviors among College Men: A Daily Diary Study.

Objective: Hookup behaviors (HUBs; i.e., sexual activity outside an exclusive relationship with no mutual expectation of romantic commitment) are prevalent on college campuses and are linked with alcohol use and sexual assault.

LAP-MALDI MS analysis of amelogenin from teeth for biological sex estimation.

The biological sex estimation of human individuals can be achieved by extracting fragments of the amelogenin protein from small areas of tooth enamel. The amelogenin gene can be found on both sex chromosomes (X and Y) with chromosome-specific differences in its sequence, and consequently the sequences of the expressed protein in teeth. Virtually all current analytical techniques used to identify the occurrence of the male Y chromosome-specific proteoform employ proteoform-specific peptide analysis by LC-ESI MS/MS, which typically results in longer analytical times due to the LC separation step, despite recent efforts of shortening the LC step.

Discovery of peptides for ligand-mediated delivery of mRNA lipid nanoparticles to cystic fibrosis lung epithelia.

For cystic fibrosis patients, a lung-targeted gene therapy would significantly alleviate pulmonary complications associated with morbidity and mortality. However, mucus in the airways and cell entry pose huge delivery barriers for local gene therapy. Here, we used phage display technology to select for and identify mucus- and cell-penetrating peptides against primary human bronchial epithelial cells from cystic fibrosis patients cultured at the air-liquid interface.

Prototype Specificity Matters When Predicting Later Alcohol-Related Content Posting and Alcohol Use Among Adolescent and Young Adults.

: Drinking prototypes (i.e., images of the type of individual who engages in specific alcohol use behaviors) are associated with alcohol use, with self-identified similarity to the prototype possibly driving this connection more than one's favorability of the prototype.

A retrospective multi-site examination of chronic kidney disease using longitudinal laboratory results and metadata to identify clinical and financial risk.

Background: A retrospective observational study was conducted at 3 health care organizations to identify clinical gaps in care for patients with stage 3 or 4 chronic kidney disease (CKD), and financial opportunity from U.S. risk adjustment payment systems.

UBA1 inhibition sensitizes cancer cells to PARP inhibitors.

Therapeutic strategies targeting the DNA damage response, such as poly (ADP-ribose) polymerase (PARP) inhibitors (PARPi), have revolutionized cancer treatment in tumors deficient in homologous recombination (HR). However, overcoming innate and acquired resistance to PARPi remains a significant challenge. Here, we employ a genome-wide CRISPR knockout screen and discover that the depletion of ubiquitin-activating enzyme E1 (UBA1) enhances sensitivity to PARPi in HR-proficient ovarian cancer cells.

Mating and ecdysone signaling modify growth, metabolism, and digestive efficiency in the female gut.

Adaptive changes in organ size and physiology occur in most adult animals, but how these changes are regulated is not well understood. Previous research found that mating in females drives not only increases in gut size and stem cell proliferation but also alters feeding behavior, intestinal gene expression, and whole-body lipid storage, suggesting altered gut metabolism. Here, we show that mating dramatically alters female gut metabolism and digestive function.
