Sodium butyrate promotes synthesis of testosterone and meiosis of hyperuricemic male mice.

Hyperuricemia (HUA) impaires spermatogenesis. This study was carried out, aiming to determine whether butyric acid (NaB) avoids the HUA-induced decline of sperm quality HUA mice were developed through intra-peritoneal injection of the potassium oxalate combined with intragastric uric acid (UA) and by tube feeding 300 mg·kg-1·d-1NaB. The effect of NaB on the reproduction of HUA male mice was determined by measuring sperm count, sperm motility and testosterone content.

Injectable Hydrogel Loaded with Plasma-Rich Platelets Repairing Endometrial Injury and Remodeling Reproductive Function by Regulating PI3K/AKT Pathway.

Infertility resulting from uterine damage has emerged as a significant challenge confronting the development of modern society. Existing therapeutic approaches frequently encounter limitations due to the intricate physical and physiological environment of uterus. Platelet-rich plasma (PRP), a concentrate of platelets enriched with various growth factors, has been used in uterine injury repair.

A Smartphone-Based M-Health Monitoring System for Arrhythmia Diagnosis.

Deep learning technology has been widely adopted in the research of automatic arrhythmia detection. However, there are several limitations in existing diagnostic models, e.g.

High Temperature Oxidation Behaviors of BaO/TiO Binary Oxide-Enhanced NiAl-Based Composites.

High temperature lubricating composites have been widely used in aerospace and other high-tech industries. In the actual application process, high temperature oxidation resistance is a very importance parameter. In this paper, BaO/TiO-enhanced NiAl-based composites were prepared by vacuum hot-press sintering.

Influence of Stress Intensity Factor on Rail Fatigue Crack Propagation by Finite Element Method.

Wheel rail rolling contact fatigue is a very common form of damage, which can lead to uneven rail treads, railhead nuclear damage, etc. Therefore, ANSYS software was used to establish a three-dimensional wheel-rail contact model and analyze the effects of several main characteristics, such as the rail crack length and crack propagation angle, on the fatigue crack intensity factor during crack propagation. The main findings were as follows: (1) With the rail crack length increasing, the position where the crack propagated by mode I moved from the inner edge of the wheel-rail contact spot to the outer edge.

VeLoc: Finding Your Car in Indoor Parking Structures.

While WiFi-based indoor localization is attractive, there are many indoor places without WiFi coverage with a strong demand for localization capability. This paper describes a system and associated algorithms to address the indoor vehicle localization problem without the installation of additional infrastructure. In this paper, we propose VeLoc, which utilizes the sensor data of smartphones in the vehicle together with the floor map of the parking structure to track the vehicle in real time.
