Most synthetic self-assemblies grow indefinitely into size-unlimited structures, whereas some biological self-assemblies autonomously regulate their size and shape. One mechanism of such self-regulation arises from the chirality of building blocks, inducing their mutual twisting that is incompatible with their long-range ordered packing and thus halts the assembly's growth at a certain stage. This self-regulation occurs robustly in thermodynamic equilibrium rather than kinetic trapping, and therefore is attractive yet elusive.

Background: Heart-type fatty acid binding proteins (FABP3) constitute a family of lipid chaperone proteins. They are found in the cytosol and enhance cellular fatty acid solubilisation, transport, and metabolism. FABP3 is highly expressed in the myocardium and is released from myocytes during myocardial damage.

Integration of biogas and liquid recirculation enhance methane production in high-solid anaerobic digestion of pig manure and rice husks.

Bioresour Technol

January 2025

Technical Department, Oriental Shiraishi Corporation, 5-6-52 Toyosu, Koto-ku, Tokyo 135-0061, Japan. Electronic address:

High-solid anaerobic digestion (HSAD) is a promising technology for treating livestock manure and agricultural waste; however, the wide application has been limited due to homogenization problems. This study established a novel HSAD system by integrating liquid and biogas recirculation (R), aiming to enhance the biogas conversion efficiency of high-solid substrates at low costs. Results showed that the highest methane yield was 357 mL/gVS in the novel HSAD system (R), 30.

Article Synopsis
  • * This study analyzed 264 Blockley isolates from different regions, identifying 10 distinct genetic clusters which led to the classification into two lineages—R and S—each with unique antimicrobial resistance profiles.
  • * Notably, lineage R, found mainly in Asia and Africa, contained strains with azithromycin resistance, while lineage S, primarily in Europe and the Americas, lacked this resistance, indicating a significant need for ongoing monitoring of these pathogens.

This study aimed to reveal individual differences between the speeds of the hand and ball and clarify the factors affecting those differences. Motion data from 20 highly skilled baseball pitchers, captured using a 16-camera motion analysis system with a sampling frequency of 1,000 hz, were used for correlation and hierarchical linear model analyses. For the hierarchical linear models, the speed of the metacarpophalangeal joint was the independent variable in the 1 level.

Integrin β2 regulates titanium particle‑induced inflammation in macrophages: aseptic loosening model.

Mol Med Rep

January 2025

Department of Orthopedic Surgery, The Second Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, Zhejiang 310000, P.R. China.

Aseptic loosening is a major complication of joint replacement surgery, characterized by periprosthetic osteolysis and chronic inflammation at the bone‑implant interface. Cells release chemokines, cytokines and other pro‑inflammatory substances that perpetuate inflammation reactions, while other particle‑stimulated macrophages promote osteoclastic bone resorption and impair bone formation. The present study investigated integrin and inflammatory cytokine expression patterns in RAW 264.

As an alternative to conventional plastic dishes, the interface between water-immiscible hydrophobic fluids, such as perfluorocarbons and silicones, permits cell adhesion and growth. Thus, it is expected to replace the petroleum-derived products in a sustainable society. However, most hydrophobic fluids are cytotoxic, which limits the range of mechanical and chemical cues exposed to the cells.

Background: The generalized estimating equation (GEE) method is widely used for analyzing longitudinal and clustered data. Although the GEE estimate for regression coefficients and sandwich covariance estimate are consistent regardless of the choice of covariance structure, they are generally biased for small sample sizes. Various researchers have proposed modified GEE methods and covariance estimators to handle small-sample bias.

High-temperature Tl decay clarifies Pb dating in early Solar System.

Nature

November 2024

GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany.

Article Synopsis
  • Radioactive nuclei that live for millions of years help us understand the Sun's formation and the nucleosynthesis happening when it was born, with lead (Pb) being a key example.
  • Recent measurements of the weak decay of ionized thallium (Tl) provided a more accurate half-life, which was found to be 4.7 times longer than previously thought, thus reducing uncertainty in our calculations.
  • Using these improved decay rates, researchers calculated lead yields in asymptotic giant branch (AGB) stars, confirmed isolation times for solar material, and validated the theory that the Sun formed in a long-lived molecular cloud.

Department of Clinical Medicine (Pharmaceutical Medicine), Graduate School of Pharmaceutical Sciences, Kitasato University, Shirokane 5-9-1, Minato-ku, Tokyo 108-8641, Japan. Electronic address:

Aims: The combination of programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) inhibitors and anticancer therapies has been in the spotlight in recent years. However, the risks associated with these combination therapies are not fully elucidated. The primary objective of this study was to evaluate the relative risk of organ-specific immune-related adverse events (irAEs) and common adverse events (AEs) in patients treated with PD-1/PD-L1 inhibitor-based combination therapies compared to those treated with PD-1/PD-L1 inhibitor monotherapy for solid tumors.

Obesity continues to represent a significant public health concern, with a broad impact from both a health and economic perspective. This analysis assesses the fiscal consequences of overweight and obesity (OAO) in Japan by capturing obesity-attributable lost tax revenue and increased government transfers using a government perspective. The fiscal burden of OAO was estimated using an age-specific prevalence model, which tracked the Japanese population across different body mass index (BMI) categories.

Chimeric antigen receptor (CAR)-T cell products, classified as Advanced Therapy Medicinal Products (ATMPs), have shown promising outcomes in cancer immunotherapy. The quality of raw and starting materials used in manufacturing is critical to ensure the efficacy and safety of CAR-T cell products and depends primarily on the selection of the right materials and the right suppliers. It is essential to consider a long-term strategy when selecting raw and starting materials to prevent delays in the supply of innovative, high-quality, and safe therapies to patients.

  • Sleep apnea is common in patients with heart failure and can worsen their health outcomes; the study examines the effects of tofogliflozin, an SGLT2 inhibitor, on this condition.
  • In the study, tofogliflozin significantly lowered the apnea-hypopnea index (AHI) in patients after 6 months, indicating reduced severity of sleep apnea.
  • Improvements in body weight and water content were seen alongside the reduction in AHI, suggesting a possible link between decreased body water and sleep apnea severity, while cardiorenal functions remained unchanged.

Peptidylarginine deiminase IV (PADI4, PAD4) deregulation promotes the development of autoimmunity, cancer, atherosclerosis and age-related tissue fibrosis. PADI4 additionally mediates immune responses and cellular reprogramming, although the full extent of its physiological roles is unexplored. Despite detailed molecular knowledge of PADI4 activation in vitro, we lack understanding of its regulation within cells, largely due to a lack of appropriate systems and tools.
