Validation Status of Electronic Sphygmomanometers in China: A National Survey.

Background: Although the information on the validation status of electronic sphygmomanometer (ES) devices in use in health care institutions and households is much more clinically relevant than that of ES models available on the market, it remains insufficient.

Methods: A national survey was conducted across all administrative regions of mainland China to assess the validation status of ESs. Fifty-eight cities were selected with stratification by municipality, provincial capital, and other cities, and health care institutions and households in each city were chosen by convenience to identify ES devices in use according to the study protocol.

Radiomics of Periprostatic Fat and Tumor Lesion Based on MRI Predicts the Pathological Upgrading of Prostate Cancer from Biopsy to Radical Prostatectomy.

Rationale And Objectives: To assess the predictive value of MRI-based radiomics of periprostatic fat (PPF) and tumor lesions for predicting Gleason score (GS) upgrading from biopsy to radical prostatectomy (RP) in prostate cancer (PCa).

Methods: A total of 314 patients with pathologically confirmed prostate cancer (PCa) after radical prostatectomy (RP) were included in the study. The patients were randomly assigned to the training cohort (n = 157) and the validating cohort (n = 157) in a 1:1 ratio.

Tendon Groove Technique: A Double-Bundle Footprint Technique for Anterior Cruciate Ligament Reconstruction.

Double-bundle (DB) anterior cruciate ligament (ACL) reconstruction has biomechanical advantages over single-bundle reconstruction. However, most studies perform the DB reconstruction with 2 femoral tunnels, which fails to provide an entire femoral footprint for ACL reconstruction. In this study, we describe a femoral double-bundle footprint technique for ACL reconstruction, named the tendon groove technique.

Insights on Immobilization of Cd Contamination in Soil: Synergic Impacts of Water Management and Bauxite Residue.

To immobilize the activity and bioavailability of soil Cd, the single treatment only flooding (F) and the combined treatments with flooding plus bauxite residue (F-B) or lime (F-L) were designed to investigate the impacts of different treatments on the toxicity and bioavailability of Cd in contaminated soil. Compared with the single treatment (F), the combined treatments (F-B and F-L) improved soil-associated organic functional groups and aggregated stability in soil. The average particle sizes of soil aggregates increased from 126 nm (F-treated soil) to 256 and 270 nm following F-B and F-L treatments, respectively.

Effects of Diabetes and Attentional Focus on Learning of a Novel Balance Task.

Background And Purpose: Chronic diabetes is a prevalent systemic disease that impairs neuromotor functioning and often leads to increased risk of falls. Adopting an external focus of attention during motor skill practice has been shown to improve learning outcomes; however, it has not been examined in this population. We examined how attentional focus instructions (internal vs external) affect balance performance and learning in older adults with and without diabetes.

MYT1L deficiency impairs excitatory neuron trajectory during cortical development.

Mutations reducing the function of MYT1L, a neuron-specific transcription factor, are associated with a syndromic neurodevelopmental disorder. MYT1L is used as a pro-neural factor in fibroblast-to-neuron transdifferentiation and is hypothesized to influence neuronal specification and maturation, but it is not clear which neuron types are most impacted by MYT1L loss. In this study, we profile 412,132 nuclei from the forebrains of wild-type and MYT1L-deficient mice at three developmental stages: E14 at the peak of neurogenesis, P1 when cortical neurons have been born, and P21 when neurons are maturing, to examine the role of MYT1L levels on neuronal development.

Molecular Basis of VCPIP1 and P97/VCP Interaction Reveals Its Functions in Post-Mitotic Golgi Reassembly.

The VCPIP1-P97/VCP (Valosin-Containing Protein) complex is required for post-mitotic Golgi cisternae reassembly and maintenance in interphase. However, the organization and mechanism of this complex in regulating Golgi membrane fusion is still elusive. Here, the cryo-electron microscopy (cryo-EM) structures of the human VCPIP1-P97/VCP complex are presented.

A Light-Driven In Vitro Enzymatic Biosystem for the Synthesis of α-Farnesene from Methanol.

Blinatumomab for MRD-Negative Acute Lymphoblastic Leukemia in Adults.

Background: Many older adults with B-cell precursor acute lymphoblastic leukemia (BCP-ALL) have a relapse despite having a measurable residual disease (MRD)-negative complete remission with combination chemotherapy. The addition of blinatumomab, a bispecific T-cell engager molecule that is approved for the treatment of relapsed, refractory, and MRD-positive BCP-ALL, may have efficacy in patients with MRD-negative remission.

Methods: In a phase 3 trial, we randomly assigned patients 30 to 70 years of age with -negative BCP-ALL (with :: indicating fusion) who had MRD-negative remission (defined as <0.

Discordant High Remnant Cholesterol With LDL-C Increases the Risk of Stroke: A Chinese Prospective Cohort Study.

Background: Previous studies focusing on assessing the effects of remnant cholesterol (RC) and low-density lipoprotein cholesterol (LDL-C) on stroke may not consider their mutual influence. We aimed to explore the associations of RC and discordant high RC with LDL-C with stroke, ischemic stroke (IS), and hemorrhagic stroke.

Methods: This prospective cohort study was conducted based on 3 cohorts of the China-PAR (Prediction for Atherosclerotic Cardiovascular Disease Risk in China) project.

Experimental Study on the Flexural Performance of Steel-Polyvinyl Alcohol Hybrid Fiber-Reinforced Concrete.

This paper explores the impact of steel-PVA hybrid fibers (S-PVA HF) on the flexural performance of panel concrete via three-point bending tests. Crack development in the concrete is analyzed through Digital Image Correlation (DIC) and Scanning Electron Microscope (SEM) experiments, unveiling the underlying mechanisms. The evolution of cracks in concrete is quantitatively analyzed based on fractal theory, and a predictive model for flexural strength (PMFS) is established.
