Open frameworks in the NaMn(PO)F fluoro-pyrophosphates system.

Three new sodium manganese fluoro-pyrophosphate compounds, namely, NaMn(PO)F (I), NaMn(PO)F (II), and NaMn(PO)F (III), have been synthesized by heating a mixture of NaPF, NaPOF or NaHPO with different Mn sources in NaNO and KNO fluxes. The structures of the title compounds were characterized single-crystal X-ray diffraction (XRD). II is characteristic of a shell of Na ions that encloses one [Mn(PO)F] unit, whereas I and III reveal three-dimensional (3D) frameworks that consist of MnO, Mn/NaOF octahedra or MnO octahedra and distorted MnO square pyramids with PO units, where Na cations reside in different-membered ring one-dimensional (1D) tunnels.

Arthroscopic Repair of Subscapularis Tendon Using a Percutaneous Continuous Sewing Machine-Like Suture Technique Through a Single Working Portal.

Tearing of the subscapularis tendon is a common shoulder injury that typically requires arthroscopic repair. The suture-passing device is a standard tool for repairing the subscapularis tendon. However, it poses the risk of device breakage and may cause additional damage to the tendon.

Xalnesiran with or without an Immunomodulator in Chronic Hepatitis B.

Background: Xalnesiran, a small interfering RNA molecule that targets a conserved region of the hepatitis B virus (HBV) genome and silences multiple HBV transcripts, may have efficacy, with or without an immunomodulator, in patients with chronic HBV infection.

Methods: We conducted a phase 2, multicenter, randomized, controlled, adaptive, open-label platform trial that included the evaluation of 48 weeks of treatment with xalnesiran at a dose of 100 mg (group 1), xalnesiran at a dose of 200 mg (group 2), xalnesiran at a dose of 200 mg plus 150 mg of ruzotolimod (group 3), xalnesiran at a dose of 200 mg plus 180 μg of pegylated interferon alfa-2a (group 4), or a nucleoside or nucleotide analogue (NA) alone (group 5) in participants with chronic HBV infection who had virologic suppression with NA therapy. The primary efficacy end point was hepatitis B surface antigen (HBsAg) loss (HBsAg level, <0.

Minipatellar Tunnels for Transosseous Fixation of Medial Patellofemoral Ligament Graft Using High-strength Suture.

Patellar dislocation is a common knee injury, with concomitant pathoanatomical risk factors that synergistically interact and predispose to patellofemoral instability. Medial patellofemoral ligament (MPFL) reconstruction has demonstrated significant potential in the re-establishment of MPFL anatomic and biological function, with low patellar redislocation rates. Although many techniques for MPFL reconstruction have been developed, challenges such as patella fractures and high costs persist.

Imperatorin promotes melanin degradation in keratinocytes through facilitating autophagy via the PI3K/Akt signaling pathway.

Purpose: Melanin's pivotal role in skin protection and its overproduction leading to hyperpigmentation disorders highlight the necessity of regulating melanogenesis, with autophagy identified as a key degradation pathway. Imperatorin, a compound from Angelica dahurica, has been revealed to reduce melanin in epidermal keratinocytes, with the specific effects and mechanisms unknown. The purpose of this study was to investigate the mechanism by which imperatorin, reduces melanin production in HaCaT cells, with a focus on its potential role in promoting autophagy and regulating the PI3K/Akt signaling pathway.

Body posture can modulate liver stiffness measured by transient elastography: a prospective observational study.

Background: Non-invasive measurement of liver stiffness (LS), traditionally performed in the supine position, has been established to assess liver fibrosis. However, fibrosis degree is not the sole determinant of LS, necessitating the identification of relevant confounders. One often-overlooked factor is body posture, and it remains unclear whether normal daily postures interfere with LS irrespective of fibrosis.

Imperceptible augmentation of living systems with organic bioelectronic fibres.

The functional and sensory augmentation of living structures, such as human skin and plant epidermis, with electronics can be used to create platforms for health management and environmental monitoring. Ideally, such bioelectronic interfaces should not obstruct the inherent sensations and physiological changes of their hosts. The full life cycle of the interfaces should also be designed to minimize their environmental footprint.

Novel Metabolites Associated With Blood Pressure After Dietary Interventions.

Background: The blood pressure (BP) etiologic study is complex due to multifactorial influences, including genetic, environmental, lifestyle, and their intricate interplays.

Methods: In the ProBP trail (Protein and Blood Pressure), a double-blinded crossover randomized controlled trial, participants underwent dietary interventions of carbohydrate, soy protein, and milk protein, receiving 40 g daily for 8 weeks, with 3-week washout periods.

MBNL3 Acts as a Target of miR-302e to Facilitate Cell Proliferation, Invasion and Angiogenesis of Gastric Adenocarcinoma via AKT/VEGFA Pathway.

Gastric adenocarcinoma (GAC) is a common, malignant type of tumor in human, and is accompanied with higher mortality. Muscleblind-like 3 (MBNL3) was found to be a pivotal participator in aggravating this cancer's progression. However, the regulatory effects of MBNL3 on GAC development have not been investigated.

Osteoporotic Precise Screening Using Chest Radiography and Artificial Neural Network: The OPSCAN Randomized Controlled Trial.

Background Diagnosing osteoporosis is challenging due to its often asymptomatic presentation, which highlights the importance of providing screening for high-risk populations. Purpose To evaluate the effectiveness of dual-energy x-ray absorptiometry (DXA) screening in high-risk patients with osteoporosis identified by an artificial intelligence (AI) model using chest radiographs. Materials and Methods This randomized controlled trial conducted at an academic medical center included participants 40 years of age or older who had undergone chest radiography between January and December 2022 without a history of DXA examination.

Multi-dimensional cell-free DNA-based liquid biopsy for sensitive early detection of gastric cancer.

Background: Gastric cancer is the fifth most common cancer type. Most patients are diagnosed at advanced stages with poor prognosis. A non-invasive assay for the detection of early-stage gastric cancer is highly desirable for reducing associated mortality.

Intensive Ambulance-Delivered Blood-Pressure Reduction in Hyperacute Stroke.

Background: Treatment of acute stroke, before a distinction can be made between ischemic and hemorrhagic types, is challenging. Whether very early blood-pressure control in the ambulance improves outcomes among patients with undifferentiated acute stroke is uncertain.

Methods: We randomly assigned patients with suspected acute stroke that caused a motor deficit and with elevated systolic blood pressure (≥150 mm Hg), who were assessed in the ambulance within 2 hours after the onset of symptoms, to receive immediate treatment to lower the systolic blood pressure (target range, 130 to 140 mm Hg) (intervention group) or usual blood-pressure management (usual-care group).

Glucosamine and Silibinin Alter Cartilage Homeostasis through Glycosylation and Cellular Stresses in Human Chondrocyte Cells.

Osteoarthritis is more prevalent than any other form of arthritis and is characterized by the progressive mechanical deterioration of joints. Glucosamine, an amino monosaccharide, has been used for over fifty years as a dietary supplement to alleviate osteoarthritis-related discomfort. Silibinin, extracted from milk thistle, modifies the degree of glycosylation of target proteins, making it an essential component in the treatment of various diseases.

Tailored UPRE2 variants for dynamic gene regulation in yeast.

Genetic elements are foundational in synthetic biology serving as vital building blocks. They enable programming host cells for efficient production of valuable chemicals and recombinant proteins. The unfolded protein response (UPR) is a stress pathway in which the transcription factor Hac1 interacts with the upstream unfolded protein response element (UPRE) of the promoter to restore endoplasmic reticulum (ER) homeostasis.

Automatic Assessment of Ultrasound Curvature Angle for Scoliosis Detection Using 3-D Ultrasound Volume Projection Imaging.

Objective: Scoliosis is a spinal deformation in which the spine takes a lateral curvature, generating an angle in the coronal plane. The conventional method for detecting scoliosis is measurement of the Cobb angle in spine images obtained by anterior X-ray scanning. Ultrasound imaging of the spine is found to be less ionising than traditional radiographic modalities.
