Student and Physician Views of How the Dobbs Decision Affects Training and Practice Location Preferences: Cross-Sectional Questionnaire Study.

Background: By allowing for abortion bans and restrictions to take effect in the majority of US states, the 2022 Dobbs v Jackson Women's Health Organization decision portends to have lasting impacts on patient care and the physician workforce. Notably, it is already beginning to impact practice location preferences of US health care workers, evidenced by declining application rates to residency programs in abortion-restrictive states since 2022. Yet, there remains a gap in the literature regarding why this trend exists.

Genetic and morphological shifts associated with climate change in a migratory bird.

Background: Rapid morphological change is emerging as a consequence of climate change in many systems. It is intuitive to hypothesize that temporal morphological trends are driven by the same selective pressures that have established well-known ecogeographic patterns over spatial environmental gradients (e.g.

Phylogenomic resolution of lampreys reveals the recent evolution of an ancient vertebrate lineage.

Jawless vertebrates once dominated Palaeozoic waters, but just two lineages have persisted to the present day: lampreys and hagfishes. Living lampreys are a relatively small clade, with just over 50 species described, but knowledge of their evolutionary relationships has always been based on either a few mitochondrial genes or a small number of taxa. Biogeographers have noted the disjunct antitropical distribution of living lamprey families.

A Brief Online Intervention to Increase Use of Nonphysical Discipline Approaches: A Randomized Controlled Trial.

Moderate levels of child disruptive behavior are common and developmentally appropriate during toddlerhood. Caregiver discipline methods influence the development of regulatory strategies in children and the trajectory of behavior problems as children develop. Spanking is a commonly used discipline method in the United States that has been found to result in negative outcomes in childhood and adulthood.

Metagenomics reveals spatial variation in cyanobacterial composition, function, and biosynthetic potential in the Winam Gulf, Lake Victoria, Kenya.

The Winam Gulf in the Kenyan region of Lake Victoria experiences prolific, year-round cyanobacterial harmful algal blooms (cyanoHABs) which pose threats to human, livestock, and ecosystem health. To our knowledge, there is limited molecular research on the gulf's cyanoHABs, and thus, the strategies employed for survival and proliferation by toxigenic cyanobacteria in this region remain largely unexplored. Here, we used metagenomics to analyze the Winam Gulf's cyanobacterial composition, function, and biosynthetic potential.

Voice Meets Swallowing: A Scoping Review of Therapeutic Connections.

Method: This scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. A literature search was performed across multiple databases (PubMed, Web of Science, and Scopus), and additional records were identified through manual searches.

Hypoxia-inducible factor 2 regulates alveolar regeneration after repetitive injury in three-dimensional cellular and in vivo models.

Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease in which repetitive epithelial injury and incomplete alveolar repair result in accumulation of profibrotic intermediate/transitional "aberrant" epithelial cell states. The mechanisms leading to the emergence and persistence of aberrant epithelial populations in the distal lung remain incompletely understood. By interrogating single-cell RNA sequencing (scRNA-seq) data from patients with IPF and a mouse model of repeated lung epithelial injury, we identified persistent activation of hypoxia-inducible factor (HIF) signaling in these aberrant epithelial cells.

The potential impact of optimal blood pressure treatment intensity to reduce disparities in dementia between Black and White individuals.

Background: Black adults have higher dementia risk than White adults. Whether tighter population-level blood pressure (BP) control reduces this disparity is unknown.

Objective: Estimate the impact of optimal BP treatment intensity on racial disparities in dementia.

Sex Differences in Participation Restriction in Social Activities Among Older Stroke Survivors: A Nationwide Study.

Background: Women experience more poststroke physical activity limitations, but sex differences in social activity participation, an important patient-reported outcome for stroke recovery, remain uncertain.

Methods: Incident stroke survivors aged ≥65 years were identified from the US NHATS (National Health and Aging Trends Study), 2011-2022. Participants were asked to report restricted participation in the past month in 2 formal activities (religious services and clubs/classes) and 2 informal activities (visiting friends/family and going out for enjoyment) in the year of stroke onset.

Functions of nitroreductases in mycobacterial physiology and drug susceptibility.

Tuberculosis is a respiratory infection that is caused by members of the complex, with (Mtb) being the predominant cause of the disease in humans. The approval of pretomanid and delamanid, two nitroimidazole-based compounds, for the treatment of tuberculosis encourages the development of more nitro-containing drugs that target Mtb. Similar to the nitroimidazoles, many antimycobacterial nitro-containing scaffolds are prodrugs that require reductive activation into metabolites that inhibit the growth of the pathogen.

Hydrogel-Gated MXene-Graphene Field-Effect Transistor for Selective Detection and Screening of SARS-CoV-2 and Bacteria.

Field-effect transistor (FET) biosensors have significantly attracted interest across various disciplines because of their high sensitivity, time-saving, and label-free characteristics. However, it remains a grand challenge to interface the FET biosensor with complex liquid media. Unlike standard liquid electrolytes containing purified protein content, directly exposing FET biosensors to complex biological fluids introduces significant sensing noise, which is caused by the abundance of nonspecific proteins, viruses, and bacteria that adsorb to the biosensor surfaces.

DHX15 and Rig-I Coordinate Apoptosis and Innate Immune Signaling by Antiviral RNase L.

During virus infection, the activation of the antiviral endoribonuclease, ribonuclease L (RNase L), by a unique ligand 2'-5'-oilgoadenylate (2-5A) causes the cleavage of single-stranded viral and cellular RNA targets, restricting protein synthesis, activating stress response pathways, and promoting cell death to establish broad antiviral effects. The immunostimulatory dsRNA cleavage products of RNase L activity (RL RNAs) recruit diverse dsRNA sensors to activate signaling pathways to amplify interferon (IFN) production and activate inflammasome, but the sensors that promote cell death are not known. In this study, we found that DEAH-box polypeptide 15 (DHX15) and retinoic acid-inducible gene I (Rig-I) are essential for apoptosis induced by RL RNAs and require mitochondrial antiviral signaling (MAVS), c-Jun amino terminal kinase (JNK), and p38 mitogen-activated protein kinase (p38 MAPK) for caspase-3-mediated intrinsic apoptosis.

Optimal Position and Orientation of an Ossicular Accelerometer for Human Auditory Prostheses.

In this study, a method for determining the optimal location and orientation of an implantable piezoelectric accelerometer on the short process of the incus is presented. The accelerometer is intended to be used as a replacement for an external microphone to enable totally implantable auditory prostheses. The optimal orientation of the sensor and the best attachment point are determined based on two criteria-maximum pressure sensitivity sum and minimum loudness level sum.

Non-Genotoxic and Environmentally Relevant Lower Molecular Weight Polycyclic Aromatic Hydrocarbons Significantly Increase Tumorigenicity of Benzo[]pyrene in a Lung Two-Stage Mouse Model.

The World Health Organization has classified air pollution as a carcinogen, and polycyclic aromatic hydrocarbons (PAHs) are major components of air particulates of carcinogenic concern. Thus far, most studies focused on genotoxic high molecular weight PAHs; however, recent studies indicate potential carcinogenicity of the non-genotoxic lower molecular weight PAHs (LMW PAHs) that are found in indoor and outdoor air pollution as well as secondhand cigarette smoke. We hypothesize that LMW PAHs contribute to the promotion stage of cancer when combined with benzo[]pyrene (B[]P), a legacy PAH.

Recommendations for Implementing Innovative Technologies to Control : Population Suppression Using a Combination of the Incompatible and Sterile Insect Techniques (IIT-SIT), Based on the Mexican Experience/Initiative.

The future of control emphasizes the transition from traditional insecticides toward more sustainable and multisectoral integrated strategies, like using -carrying mosquitoes for population suppression or replacement. We reviewed the integration of the successful Mexican initiative, "Mosquitos Buenos", with the key challenges outlined in the PAHO guidelines for incorporating innovative approaches into vector control programs. These challenges include establishing essential infrastructure, training personnel, managing field operations, and fostering community support.

Inheritance and Resistance Mechanisms of Field-Evolved Resistance to Pyrethroids in a Fall Armyworm ( J.E. Smith) (Lepidoptera: Noctuidae) Strain from Puerto Rico.

This study examines resistance inheritance to the pyrethroid insecticides esfenvalerate and deltamethrin in a Puerto Rican strain of fall armyworm (FAW), , a major global pest of corn. The resistant strain (PPR) showed significantly higher resistance compared to a susceptible strain (SUS), with a 62-fold X-linked and 15-fold autosomal-linked resistance ratio (RR) for esfenvalerate and deltamethrin, respectively. Resistance was incompletely dominant for both insecticides.

A Possible Phenotype-to-Genotype Association of Novel Single-Nucleotide Variants in the Coding Exons of the Gene to Arterial Aneurysmal and Dissection Diseases.

After reporting the first known clinical case associating compound heterozygous single-nucleotide variants in Exon 2 of to aortic aneurysmal and iliac dissection, we began prospective surveillance in our vascular genetic practice for similar cases. Herein, we present nine (9) subjects from a total cohort of 135 with arterial aneurysms or dissections who revealed single-nucleotide variants in with no other alterations in a panel of 35 genes associated with aneurysmal and dissection disorders. Five out of nine (5/9) single-nucleotide variants were in Exon 1, and four out of nine (4/9) mutations were in Exon 2, both of which are principal coding exons for this gene.

Complexities, Benefits, Risks, and Clinical Implications of Sodium Bicarbonate Administration in Critically Ill Patients: A State-of-the-Art Review.

Sodium bicarbonate has been used in the treatment of different pathologies, such as hyperkalemia, cardiac arrest, tricyclic antidepressant toxicity, aspirin toxicity, acute acidosis, lactic acidosis, diabetic ketoacidosis, rhabdomyolysis, and adrenergic receptors' resistance to catecholamine in patients with shock. An ongoing debate about bicarbonate's efficacy and potential harm has been raised for decades because of the lack of evidence supporting its potential efficacy. Despite the guidelines' restrictions, sodium bicarbonate has been overused in clinical practice.

Controlled Dynamic Microfluidic Culture of Murine, Bovine, and Human Embryos Improves Development: Proof-of-Concept Studies.

Classical preimplantation embryo culture is performed in static fluid environments. Whether a dynamic fluid environment, like the fallopian tube, is beneficial for embryo development remains to be determined across mammalian species. Objectives of these proof-of-concept studies were to determine if controllable dynamic microfluidic culture would enhance preimplantation murine, bovine, and human embryo development compared to static culture.

Mechanical Stretch Control of Adipocyte AKT Signaling and the Role of FAK and ROCK Mechanosensors.

Adipose tissue in vivo is physiologically exposed to compound mechanical loading due to bodyweight bearing, posture, and motion. The capability of adipocytes to sense and respond to mechanical loading milieus to influence metabolic functions may provide a new insight into obesity and metabolic diseases such as type 2 diabetes (T2D). Here, we evidenced physiological mechanical loading control of adipocyte insulin signaling cascades.
