Aims: To investigate glycaemic control in Chinese adults with type 2 diabetes (T2D) initiating, or switching to insulin degludec/insulin aspart (IDegAsp), a co-formulation of basal, and bolus insulin, in a real-world setting.

Materials And Methods: A 20-week, prospective, single-arm, open-label, non-interventional study was conducted in Chinese adults with T2D initiating, or switching to IDegAsp after anti-hyperglycaemic treatment with oral antidiabetic drugs (OADs), other insulins, or glucagon-like peptide-1 receptor agonists. The primary endpoint was a change in HbA from baseline to end of the study; the secondary endpoints included a change in fasting plasma glucose and Diabetes Treatment Satisfaction Questionnaire (DTSQ) score.

Background: Diabetes, a chronic disease necessitating long-term treatment and self-management, presents significant challenges for patients who spend most of their treatment time outside of hospitals. The potential of digital therapeutics for diabetes has garnered recognition from different organizations. Although some prior studies have demonstrated successful reductions in patients' blood glucose levels and body weight through digital diabetes programs, many studies were limited by including prediabetes patients, patients treated with mostly premixed insulin, or evaluating user engagement outcomes rather than clinical outcomes.

The outbreak of emerging acute viral diseases urgently requires the acceleration of specialized antiviral drug development, thus widely adopting phenotypic screening as a strategy for drug repurposing in antiviral research. However, traditional phenotypic screening methods typically require several days of experimental cycles and lack visual confirmation of a drug's ability to inhibit viral infection. Here, we report a robust method that utilizes quantum-dot-based single-virus tracking and machine learning to generate unique single-virus infection fingerprint data from viral trajectories and detect the dynamic changes in viral movement following drug administration.

Traditional Chinese Medicine (TCM) has demonstrated promising efficacy in managing and preventing the early‑stage diabetic nephropathy (DN). Although the exact mechanisms remain elusive, clinical evidence has suggested that Jinlida granules (JLD) are beneficial in improving renal function among patients with DN. The present study aimed to elucidate the effect of JLD on DN and the underlying molecular mechanism.

Article Synopsis
  • The study reveals that microplastics (MPs), particularly polyvinyl chloride (PVC) MPs, are more harmful to thick-shelled mussels compared to kaolin, with the exception of physical damage.
  • Researchers found that chemicals in MPs contribute significantly to their toxicity, indicating that both physical and chemical factors negatively impact mussels.
  • The experiments highlight the importance of including natural particles in microplastics research, suggesting that the chemical composition of MPs plays a crucial role in their harmful effects on marine life.

As a key component, the performance of pantograph slide plate is directly related to the normal operation of train and the stability of power supply. The pantograph slide plate is exposed to the complex environment and thus it would face mechanical impacts. In this paper, two types of slide plate models (wide and narrow) are constructed to explore the mechanical behavior of pantograph slide plate under impact using the finite element method.

High-power mid-infrared fiber lasers, featuring superior beam quality and good power-scaling ability, have a few important applications in material processing, medical surgery, and molecule spectroscopy. The high-power pump light combiner, as one of the key elements for constructing a mid-infrared fiber laser, is crucial for the laser performance. While some advanced side-pump combiners based on fluoride fiber have been reported in recent literatures, the thermal stability of the fluoride fiber combiner, which is closely-related to its power-scaling capability, is a long-living challenge.

Article Synopsis
  • EphrinB2 is crucial for promoting the formation of blood and lymph vessels during embryo development and plays a significant role in cardiac lymphangiogenesis after a heart attack (myocardial infarction, MI).
  • The study found that EphrinB2 helps prevent heart remodeling and dysfunction post-MI by activating pathways involved in lymphangiogenesis, with its absence leading to worsening heart conditions.
  • Mechanistically, EphrinB2 enhances the proliferation and migration of lymphatic endothelial cells, boosts the activity of a specific transcription factor (ISL1), and its effects are diminished when the VEGFR3 pathway is inhibited, highlighting its importance in cardiac recovery after MI.

We demonstrate an approach successfully measuring very small nuclear isomeric excitation cross sections (on the order of 10 to 100 picobarns) via laser-cluster interaction. The interaction between an intense laser pulse and Kr atomic clusters generates a high-temperature and high-density plasma ball in which nuclear excitations are facilitated by inelastic electron scattering. The electron temperature reaches several hundred keV (corresponding to 10[Formula: see text] K), similar to a stellar environment.

  • This study investigates how clinical and synovial biomarkers can predict poor responses to adalimumab treatment in patients with rheumatoid arthritis (RA).
  • It included 56 RA patients with inadequate response to methotrexate and conducted a range of assessments before and after 12 weeks of adalimumab treatment.
  • The results showed that 42.9% of patients were non-responders, and higher plasma cell infiltration in synovial tissue was identified as an independent risk factor for inadequate treatment response, suggesting potential targets for personalized therapies.

Thermoplastic composites are gaining widespread application in aerospace and other industries due to their superior durability, excellent damage resistance, and recyclability compared to thermosetting materials. This study aims to enhance the lap shear strength (LSS) of resistance-welded GF/PP (glass fiber-reinforced polypropylene) thermoplastic composites by modifying stainless steel mesh (SSM) heating elements using a silane coupling agent. The influence of oxidation temperature, solvent properties, and solution pH on the LSS of the welded joints was systematically evaluated.

α-Aryl imides are common structural motifs in bioactive molecules and proteolysis-targeting chimeras designed for targeted protein degradation. An asymmetric Ni-catalyzed reductive cross-coupling of imide electrophiles and (hetero)aryl halides has been developed to synthesize enantioenriched α-arylglutarimides from simple starting materials. Judicious selection of electrophile pairs allows for coupling of both electron-rich and electron-deficient (hetero)aryl halides in good yields and enantioselectivities.

The hospital indoor environment has a crucial impact on the microbial exposures that humans encounter. Resistance to antibiotics is a mechanism used by bacteria to develop resilience in indoor environments, and the widespread use of antibiotics has led to changes in the ecological function of resistance genes and their acquisition by pathogens. By integrating the 16S rRNA Illumina sequencing and high-throughput-quantitative PCR approaches with water and air dust samples across seven departments in Peking University Shenzhen Hospital, China, this study yields intriguing findings regarding the department-specific variations, correlations and source tracing of bacteria, antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) within the hospital indoor environment.

MYC is one of the most extensively studied oncogenic proteins and is closely associated with the occurrence and progression of many tumors. Previous studies have shown that MYC regulates cell fate through its liquid-liquid phase separation mechanism, which is dependent on two disordered domains within its N-terminal transcriptional activation regions. In this study, we revealed that the negatively charged conserved region (E242-E261) of the MYC protein controls its condensation formation and irreversible aggregation through multivalent electrostatic interactions.

Background And Aims: The disrupted homeostasis of branched-chain amino acids (BCAAs, including leucine, isoleucine, and valine) has been strongly correlated with diabetes with a potential causal role. However, the relationship between BCAAs and diabetic kidney disease (DKD) remains to be established. Here, we show that the elevated BCAAs from BCAAs homeostatic disruption promote DKD progression unexpectedly as an independent risk factor.
