State Key Laboratory for Manufacturing System Engineering, State Industry-Education Integration Center for Medical Innovations, International Joint Laboratory for Micro/Nano Manufacturing and Measurement Technologies, Shaanxi Innovation Center for Special Sensing and Testing Technology in Extreme En

Continuous monitoring of cardiovascular vital signs can reduce the incidence and mortality of cardiovascular diseases, yet cannot be implemented by current technologies because of device bulkiness and rigidity. Here, we report self-adhesive and skin-conformal ultrasonic transducer arrays that enable wearable monitoring of multiple hemodynamic parameters without interfering with daily activities. A skin-adaptive focused ultrasound method with rational array design is proposed to implement measurement under wide ranges of skin curvatures and depths with improved sensing performances.

Influenza A viruses remain a global health threat, yet no universal antibody therapy exists. Clinical programs have centered on neutralizing mAbs, only to be thwarted by strain specificity and rapid viral escape. We instead engineered three non-neutralizing IgG2a mAbs that target distinct, overlapping epitopes within the conserved N terminus of the M2 ectodomain (M2e).

Sterols are essential isoprenoid derivatives that contribute to membrane structure and function. In plants, they also serve as precursors to phytohormones and specialized metabolites important for development, defense, and health. Although the sterol biosynthetic pathway is considered well-characterized, we report the discovery of a plant-specific cytochrome -like protein, CB5LP, as a critical component of phytosterol biosynthesis.

Sci Adv

September 2025

Department of Bioengineering and Therapeutic Sciences, University of California, San Francisco, San Francisco, CA, USA.

Breastfeeding is essential for reducing infant morbidity and mortality, yet exclusive breastfeeding rates remain low, often because of insufficient milk production. The molecular causes of low milk production are not well understood. Fresh milk samples from 30 lactating individuals, classified by milk production levels across postpartum stages, were analyzed using genomic and microbiome techniques.

Department of Mechanical Engineering, University of California, Santa Barbara, Santa Barbara, CA 93106, USA.

Endotracheal intubation is a critical medical procedure for protecting a patient's airway. Current intubation technology requires extensive anatomical knowledge, training, technical skill, and a clear view of the glottic opening. However, all of these may be limited during emergency care for trauma and cardiac arrest outside the hospital, where first-pass failure is nearly 35%.

Hepatocyte apoptosis is a key feature of metabolic dysfunction-associated steatohepatitis (MASH), but the fate of apoptotic hepatocytes in MASH is poorly understood. Here, we explore the hypotheses that clearance of dead hepatocytes by liver macrophages (efferocytosis) is impaired in MASH because of low expression of the efferocytosis receptor T cell immunoglobulin and mucin domain containing 4 (TIM4; gene ) by MASH liver macrophages, which then drives liver fibrosis in MASH. We show that apoptotic hepatocytes accumulate in human and experimental MASH, using mice fed the fructose-palmitate-cholesterol (FPC) diet or the high-fat, choline-deficient amino acid-defined (HF-CDAA) diet.

Functional, immunogenetic, and structural convergence in influenza immunity between humans and macaques.

Sci Transl Med

September 2025

Vaccine Research Center (VRC), National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA.

Human B cell immunity to the influenza hemagglutinin (HA) stem, a universal vaccine target, is often stereotyped and immunogenetically restricted, posing hurdles to study outside of humans. Here, we show that cynomolgus macaques vaccinated with an HA stem immunogen elicit humanlike public B cell lineages targeting two major conserved sites of vulnerability, the central stem and anchor epitopes. Central stem antibodies were predominantly derived from V1-138, the macaque homolog of human V1-69, a V gene preferentially used in human central stem broadly neutralizing antibodies (bnAbs).

Cachexia, the loss of skeletal muscle mass and function with cancer, contributes to reduced life quality and worsened survival. Skeletal muscle fibrosis leads to disproportionate muscle weakness; however, the role of infiltrating immune cells and fibro-adipogenic progenitors (FAPs) in cancer-induced muscle fibrosis is not well understood. Using the C26 model of cancer cachexia, we sought to examine the changes to skeletal muscle immune cells and FAPs which contribute to excessive extracellular matrix (ECM) collagen deposition.

Volunteering With Mild Cognitive Impairment: Implications for Subsequent Cognitive Changes.

Gerontologist

September 2025

Department of Child Development and Family Studies, College of Human Ecology, Seoul National University, Seoul, South Korea.

Background And Objectives: Volunteering has cognitive benefits in later life and has been theorized to protect against Alzheimer's disease and related dementias (ADRD). A small but growing body of volunteer programs target people with mild cognitive impairment (MCI)-who are presumably at elevated risk for ADRD, but we know surprisingly little about who volunteers with MCI and how volunteering affects their subsequent cognitive changes. The current study sought to address these gaps.

Background And Objectives: Over 12% of older Latinos in the United States have Alzheimer's disease and related dementias (ADRD), facing earlier onset of the disease and severe symptoms compared to non-Hispanic Whites. These disparities in ADRD among Latinos can lead to significant caregiver strain and burden in Latino ADRD caregivers. Notably, Latino ADRD caregivers have poor overall health outcomes and face systemic inequities including limited access to quality dementia care resources that impact their well-being significantly.

Background: While screening for cervical, colorectal, and lung cancers reduce cancer-specific mortality, the full benefits of screening are only realized when coupled with timely care across the subsequent "screening continuum" steps, including surveillance (results warranting frequent monitoring), diagnostic evaluation (results that require additional testing), and treatment (detected cancers). Our goal was to describe the proportion of individuals receiving timely cervical, colorectal, and lung cancer care at each step in the screening continuum.

Methods: This retrospective cohort study used data from the 10 health care settings that participate in the Population-based Research to Optimize the Screening Process (PROSPR II) consortium and included individuals who were eligible for a step along the cancer screening continuum in 2018.

Dynamic regulation of the oxidative stress response by the E3 ligase TRIP12.

Cell Rep

September 2025

Department of Molecular and Cell Biology, University of California at Berkeley, Berkeley, CA 94720, USA; Howard Hughes Medical Institute, University of California at Berkeley, Berkeley, CA 94720, USA; California Institute for Quantitative Biosciences (QB3), University of California at Berkeley, Berk

Centered on the transcription factor NRF2 and its E3 ligase CUL3, the oxidative stress response protects cells from damage by reactive oxygen species (ROS). Increasing ROS inhibits CUL3 to stabilize NRF2 and elicit antioxidant gene expression, while cells recovering from stress rapidly turn over NRF2 again to prevent reductive stress and oxeiptosis-dependent death. How cells reinitiate NRF2 degradation after ROS have been cleared remains poorly understood.

Cryo-EM structure of a type VI secretion system-delivered membrane-depolarizing toxin involved in bacterial antagonism.

Cell Rep

September 2025

Michael DeGroote Institute for Infectious Disease Research, McMaster University, Hamilton, ON L8S 4K1, Canada; Department of Biochemistry and Biomedical Sciences, McMaster University, Hamilton, ON L8S 4K1, Canada; David Braley Center for Antibiotic Discovery, McMaster University, Hamilton, ON L8S 4K

Many Gram-negative bacteria use type VI secretion systems (T6SSs) to deliver toxic effector proteins into neighboring cells. Proteins in the VasX toxin family form ion-permeable channels in the bacterial cytoplasmic membrane that dissipate the proton motive force, thereby interfering with essential physiological processes. However, the structure of any VasX family effector has remained unknown.
