Metformin reduces the risk of frailty: evidence from a Mendelian randomization study.

Background: Metformin is a widely used antidiabetic agent for obesity-related type 2 diabetes mellitus, providing significant health benefits such as reduced blood glucose levels and body weight. Emerging evidence suggests that metformin may play a beneficial role in delaying aging. However, the causal relationship between metformin use and frailty index (FI) remains uncertain and warrants further investigation.

Comparison of incidence trends of early-onset and late-onset type 2 diabetes in the Asia-Pacific region, 1990-2021: a join point regression analysis based on the global burden of disease study 2021.

Introduction: This study evaluated the incidence trends of early-onset (diagnosed at ages 15-39) and late-onset (diagnosed at age 40 and above) type 2 diabetes mellitus (T2DM) in the Asia-Pacific region, including the World Health Organization (WHO) South-East Asia Region (SEARO) and Western Pacific Region (WPRO), and assessed the impact of the COVID-19 pandemic.

Methods: Using data from the Global Burden of Diseases Study (GBD) 2021, we analyzed trends in age-standardized incidence rate (ASIR) using Join point regression to determine annual percentage change (APC). To assess the pandemic's impact, we calculated excess incidence for 2020 and 2021 by subtracting predicted ASIR from observed ASIR.

Strategies of formulation and lyophilization process for sodium chloride-mannitol-protein-based products.

Sodium chloride (NaCl) serves as a necessary stabilizer for some proteins, yet it presents an unfriendly eutectic melting temperature and can easily lead to collapse for lyophilized products. Mannitol, serving as bulking agent with property of high eutectic melting point, can provide good mechanical support for lyophilized cake to avoid collapse, therefore it is applied for lyophilized formulations containing NaCl. However, the combination of NaCl and mannitol in formulations often results in structural collapse in lyophilization process due to unproper ratio or lyophilization recipe.

Real-Time Trajectory Smoothing and Obstacle Avoidance: A Method Based on Virtual Force Guidance.

In dynamic environments, real-time trajectory planners are required to generate smooth trajectories. However, trajectory planners based on real-time sampling often produce jerky trajectories that necessitate post-processing steps for smoothing. Existing local smoothing methods may result in trajectories that collide with obstacles due to the lack of a direct connection between the smoothing process and trajectory optimization.

Multipeak Coercive Electric-Field-Based Multilevel Cell Nonvolatile Memory With Antiferroelectric-Ferroelectric Field-Effect Transistors (FETs).

An ultralow program/erase voltage ( |V| = 4 V) is demonstrated by using an antiferroelectric-ferroelectric field-effect transistor (AFE-FE-FET) through a multipeak coercive E -field ( E ) concept for a four-level stable state with outstanding endurance (>10 cycles) and data retention (>10 s at 65 °C). The mixture of ferroelectric (FE) and AFE domains can provide stable multistate and data storage with zero bias for multilevel cell (MLC) applications. HfZrO (HZO) with AFE-FE assembles an orthorhombic/tetragonal (o/t) phase composition and is achieved by [Zr] modulation in an HZO system.

Unipolar Parity of Ferroelectric-Antiferroelectric Characterized by Junction Current in Crystalline Phase HfZrO Diodes.

Ferroelectric (FE) HfZrO is a potential candidate for emerging memory in artificial intelligence (AI) and neuromorphic computation due to its non-volatility for data storage with natural bi-stable characteristics. This study experimentally characterizes and demonstrates the FE and antiferroelectric (AFE) material properties, which are modulated from doped Zr incorporated in the HfO-system, with a diode-junction current for memory operations. Unipolar operations on one of the two hysteretic polarization branch loops of the mixed FE and AFE material give a low program voltage of 3 V with an ON/OFF ratio >100.

Olfactory ensheathing cells improve the survival of porcine neural xenografts in a Parkinsonian rat model.

Background: Parkinson's disease (PD) features the motor control deficits resulting from irreversible, progressive degeneration of dopaminergic (DA) neurons of the nigrostriatal pathway. Although intracerebral transplantation of human fetal ventral mesencephalon (hfVM) has been proven effective at reviving DA function in the PD patients, this treatment is clinically limited by availability of hfVM and the related ethical issues. Homologous tissues to hfVM, such as porcine fetal ventral mesencephalon (pfVM) thus present a strong clinical potential if immune response following xenotransplantation could be tamed.
