Stem Cell Secretome Treatment Reduces Adiposity and Improves Glucose Handling During Obesity and Weight Loss in Mice

Obesity, EarlyView.
ABSTRACT Objective In this study, we investigated the effects of a stem cell‐derived secretome product on adiposity and tissue quality and insulin and glucose levels in obese mice and those undergoing dietary weight loss. Methods Following 16 weeks of high fat diet mice received acute (4 weeks) biweekly intramuscular injections with vehicle or ...

Carbon and oxygen in metal-poor halo stars

, 2019
Carbon and oxygen are key tracers of the Galactic chemical evolution; in particular, a reported upturn in [C/O] towards decreasing [O/H] in metal-poor halo stars could be a signature of nucleosynthesis by massive Population III stars. We reanalyse carbon,

Exploration of the use of short‐wave infrared radiances in weather forecasts model Part II: Data assimilation and forecast impact assessment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The standalone non‐local thermodynamic equilibrium (NLTE) bias correction schemes, utilizing a look‐up‐table and a linear regression method developed in Part I and new quality control procedures for short‐wave infrared radiances (SWIR), were tested within a data assimilation framework.

Efficacy and safety of anifrolumab across organ domains of systemic lupus erythematosus: A systematic review and meta‐analysis

Rheumatology &Autoimmunity, EarlyView.
A systematic review and meta‐analysis were conducted to review all clinical trial results of anifrolumab for treating systemic lupus erythematosus. Fourteen studies were included comprising 1322 patients and five studies were meta‐analyzed. It was found that anifrolumab 300 mg IV led to clinical improvement across composite lupus scores, cutaneous ...

Non-LTE Abundances and Consequences for the Evolution of the alpha elements in the Galaxy

, 2000
Abundances of alpha-elements such as Ca and Mg in disk and halo stars are usually derived from equivalent widths lines measured on high resolution spectra, and assuming Local Thermodynamic Equilibrium (LTE) .

System Integration and Field Testing of Low‐Cost Autonomous Platooning Platforms: Collision Avoidance Scenario

Journal of Field Robotics, EarlyView.
ABSTRACT This paper presents the development and validation of a scalable platooning system based on the predecessor‐following (PF) topology, designed for low‐cost follower platforms. It integrates key technologies such as localization, path planning, profile generation, and low‐level control to create a practical solution.
