Antiviral Mx proteins have an ancient origin and widespread distribution among eukaryotes.

Mx proteins, first identified in mammals, encode potent antiviral activity against a wide range of viruses. Mx proteins arose within the Dynamin superfamily of proteins (DSP), which mediate critical cellular processes, such as endocytosis and mitochondrial, plastid, and peroxisomal dynamics. Despite their crucial role, the evolutionary origins of Mx proteins are poorly understood.

Macromolecular interactions and geometrical confinement determine the 3D diffusion of ribosome-sized particles in live cells.

The crowded bacterial cytoplasm is composed of biomolecules that span several orders of magnitude in size and electrical charge. This complexity has been proposed as the source of the rich spatial organization and apparent anomalous diffusion of intracellular components, although this has not been tested directly. Here, we use biplane microscopy to track the 3D motion of self-assembled bacterial genetically encoded multimeric nanoparticles (bGEMs) with tunable size (20 to 50 nm) and charge (-3,240 to +2,700 e) in live cells.

A split-GAL4 driver line resource for neuron types.

Techniques that enable precise manipulations of subsets of neurons in the fly central nervous system (CNS) have greatly facilitated our understanding of the neural basis of behavior. Split-GAL4 driver lines allow specific targeting of cell types in and other species. We describe here a collection of 3060 lines targeting a range of cell types in the adult CNS and 1373 lines characterized in third-instar larvae.

Altered Effective Connectivity Within a Thalamocortical Corollary Discharge Network in Individuals With Schizophrenia.

Background And Hypothesis: Sequential saccade planning requires corollary discharge (CD) signals that provide information about the planned landing location of an eye movement. These CD signals may be altered among individuals with schizophrenia (SZ), providing a potential mechanism to explain passivity and anomalous self-experiences broadly. In healthy controls (HC), a key oculomotor CD network transmits CD signals from the thalamus to the frontal eye fields (FEF) and the intraparietal sulcus (IPS) and also remaps signals from FEF to IPS.

Distributed lag models for retrospective cohort data with application to a study of built environment and body weight.

Distributed lag models (DLMs) estimate the health effects of exposure over multiple time lags prior to the outcome and are widely used in time series studies. Applying DLMs to retrospective cohort studies is challenging due to inconsistent lengths of exposure history across participants, which is common when using electronic health record databases. A standard approach is to define subcohorts of individuals with some minimum exposure history, but this limits power and may amplify selection bias.

Associations between the gut microbiome, inflammation and cardiovascular profiles in people with HIV.

Background: Inflammation and innate immune activation are associated with chronic HIV infection, despite effective treatment. Although gut microbiota alterations are linked to systemic inflammation, the relationships between the gut microbiome, inflammation and HIV remain unclear.

Methods: The UPBEAT-CAD sub-study, examining cardiovascular disease (CVD) risk in HIV, enrolled participants matched on HIV status and traditional CVD risk factors.

Deciphering the Neural Effects of Emotional, Motivational, and Cognitive Challenges on Inhibitory Control Processes.

Converging lines of research indicate that inhibitory control is likely to be compromised in contexts that place competing demands on emotional, motivational, and cognitive systems, potentially leading to damaging impulsive behavior. The objective of this study was to identify the neural impact of three challenging contexts that typically compromise self-regulation and weaken impulse control. Participants included 66 healthy adults (M/SD = 29.

Regulatory B-Cells Are Associated Negatively With Regulatory T-Cells and Positively With Cytokines in Peripheral Blood of Pregnant Women.

Problem: Regulatory B-cells (Bregs, CD19CD24CD38) are a specialized B-cell subset that suppresses immune responses and potentially contribute to the maintenance of an immune-privileged environment for fetal development during pregnancy. However, little is known about the surrounding immunological environment of Bregs in gestational physiology. The relationship of regulatory T-cells (Tregs, CD4CD25CD127FoxP3) to Bregs in coordinating immunoregulation during pregnancy is unknown.

mHealth-Based Diabetes Prevention Program for Chinese Mothers With Abdominal Obesity: Randomized Controlled Trial.

Background: Among people with abdominal obesity, women are more likely to develop diabetes than men. Mobile health (mHealth)-based technologies provide the flexibility and resource-saving opportunities to improve lifestyles in an individualized way. However, mHealth-based diabetes prevention programs tailored for busy mothers with abdominal obesity have not been reported yet.

Exploring Health Educational Interventions for Children With Congenital Heart Disease: Scoping Review.

Background: Congenital heart disease (CHD) is the most common birth defect, affecting 40,000 births annually in the United States. Despite advances in medical care, CHD is often a chronic condition requiring continuous management and education. Effective care management depends on children's understanding of their condition.

Review on the o-aminoaniline Moiety in Peptide and Protein Chemistry.

Peptides and proteins are important functional biomolecules both inside and outside of living organisms. The ability to prepare various types of functionalized peptides and proteins is essential for understanding fundamental biological processes, such as protein folding and post-translational modifications (PTMs), and for developing new therapeutics for many diseases, such as cancers and neurodegenerative diseases. The o-aminoaniline moiety was first proposed for activation to a thioester precursor and used for native chemical ligation to prepare large peptides and proteins.

Cognitive impairment and limited health literacy are associated with poor health outcomes among patients with heart failure residing in rural areas.

Background: Cognitive impairment and limited health literacy are prevalent among patients with heart failure, particularly those residing in rural areas, and are linked to poor health outcomes. Little is known about the intricate relationships among cognitive function, health literacy, and rehospitalization and death in rural patients with heart failure.

Objectives: To determine the relationships among cognitive function, health literacy, and cardiac event-free survival (ie, heart failure hospitalizations and cardiac mortality) in rural patients with heart failure.

Enhanced Transcriptional Activation in Developing Mouse Photoreceptors.

Purpose: Retinal development in the mouse continues past birth and provides a widely used model system in which photoreceptor formation can be observed and manipulated. This experimental paradigm provides opportunities for both gain-of-function and loss-of-function studies, which can be accomplished through in vivo or ex vivo plasmid delivery and electroporation. However, the cis-regulatory elements used to implement this approach have not been fully evaluated or optimized for the unique transcriptional environment of photoreceptors.

Preferential Sites of Retinal Capillary Occlusion in Sickle Cell Disease.

Purpose: To assess the preferential sites of retinal capillary occlusion at the parafovea in patients with sickle cell disease (SCD) using optical coherence tomography angiography (OCT-A).

Methods: OCT-A scans from 107 patients with SCD and 51 race-matched unaffected controls were obtained using a commercial spectral domain-OCT system. At least eight sequential 3 × 3 mm scans centered at the fovea were acquired and averaged for image analysis.

Benefit Design and Access to Dental Care Among Seniors With Medicare Advantage Dental Benefits.

Importance: Although Medicare Advantage plans frequently offer dental benefits, enrollees report lower rates of dental care use and higher rates of unmet dental need compared with individuals with employer-sponsored benefits. It is unknown which attributes of Medicare Advantage dental plans are associated with enhanced dental care access.

Objective: To determine attributes of Medicare Advantage dental plans associated with higher rates of dental care use and lower rates of unmet dental need.

Incidence Rate Trends of Breast Cancer Overall and by Molecular Subtype by Race and Ethnicity and Age.

Importance: Black and Hispanic women in the US experience higher incidence rates of aggressive molecular subtypes of breast cancer, including triple-negative disease. However, how these rates are changing, particularly across different age groups, has not been well documented.

Objective: To assess changes in overall and subtype-specific breast cancer incidence rates in the US by age and race and ethnicity.

Duration in Immigration Detention and Health Harms.

Importance: Length of custody is a mechanism by which carceral systems can worsen health. However, there are fewer studies examining US immigration detention, in large part because US immigration detention is largely privately operated and opaque by design.

Objectives: To examine the association between duration spent in US immigration detention with subsequent health outcomes.

City-Level Sugar-Sweetened Beverage Taxes and Changes in Adult Body Mass Index.

Importance: Sugar-sweetened beverage (SSB) excise taxes are popular policy interventions aimed at decreasing SSB purchasing and consumption to improve cardiometabolic health and generate revenue for public health initiatives. There is limited evidence that these taxes in the US are associated with weight-related outcomes in adults, a primary contributor to cardiometabolic health.

Objective: To determine the association between SSB excise taxes and adult body mass index (BMI) and proportion of adults with overweight or obesity among California cities and assess whether associations vary by demographic characteristics.

Outpatient Low-Dose Initiation of Buprenorphine for People Using Fentanyl.

Importance: The rise of high-potency opioids such as fentanyl makes buprenorphine initiation challenging due to the risks of precipitated withdrawal, prompting the exploration of strategies, such as low-dose initiation (LDI) of buprenorphine. However, no comparative studies on LDI outcomes exist.

Objective: To evaluate outpatient outcomes associated with 2 LDI protocols of buprenorphine among individuals with opioid use disorder (OUD) using fentanyl.

COVID-19 Pandemic and Racial and Ethnic Disparities in Long-Term Nursing Home Stay or Death Following Hospital Discharge.

Importance: Long-term nursing home stay or death (long-term NH stay or death), defined as new long-term residence in a nursing home or death following hospital discharge, is an important patient-centered outcome.

Objective: To examine whether the COVID-19 pandemic was associated with changes in long-term NH stay or death among older adults with sepsis, and whether these changes were greater in individuals from racial and ethnic minoritized groups.

Design, Setting, And Participants: This cross-sectional study used patient-level data from the Medicare Provider Analysis and Review File, the Master Beneficiary Summary File, and the Minimum Data Set.

Ketogenic Diet-Associated Worsening of Osteoarthritis Histologic Secerity, Increased Pain Sensitivity and Gut Microbiome Dysbiosis in Mice.

The objective of this study was to evaluate a well-formulated ketogenic diet (KD) in the context of knee OA histology and pain using the destabilization of the medial meniscus (DMM) mouse model and correlate with gut microbiome and systemic cytokine levels.

Methods: Adult male mice underwent unilateral DMM or sham surgery and were then fed eight weeks of KD or chow.

Estimated Pulse Wave Velocity Is Associated With All-Cause Mortality and Cardiovascular Mortality Among Adults With Chronic Kidney Disease.

This study aimed to assess the correlation between estimated pulse wave velocity (ePWV) and mortality rates related to all-cause and cardiovascular disease (CVD) among individuals diagnosed with chronic kidney disease (CKD) in the United States. A total of 4669 participants with CKD were identified from the National Health and Nutrition Examination Survey conducted between 1999 and 2018. We calculated the incidence of CKD using an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.

Platform Selection for Patients Undergoing Transcatheter Aortic Valve Replacement: A Practical Approach.

Transfemoral transcatheter aortic valve Replacement (TAVR) has become the standard therapy for patients with severe aortic stenosis in patients over 75 years old in Europe or 65 years old in the United States, regardless of the surgical risk. Furthermore, iterations of existing transcatheter aortic valves (TAVs), as well as devices with novel concepts, have provided substantial improvements with respect to the limitations of previous-generation devices. Hence, treatment of a broader spectrum of patients has become feasible, and a sophisticated selection of the appropriate TAV tailored to patients' anatomy and comorbidities is now possible.
