This paper proposes a method to control the sensitivity of a ring MEMS gyroscope by adjusting the driving control voltage via MEMS. The aim is to explore the relationship between the range of the ring MEMS gyroscope and the driving control voltage, establishing a mathematical model that correlates driving control voltage with sensitivity. By applying different driving voltages to the same gyroscope, the study evaluates the performance and range of the gyroscope.

Batteries based on sulfur cathodes offer a promising energy storage solution due to their potential for high performance, cost-effectiveness, and sustainability. However, commercial viability is challenged by issues such as polysulfide migration, volume changes, uneven phase nucleation, limited ion transport, and sluggish sulfur redox kinetics. Addressing these challenges requires insights into the structural, morphological, and chemical evolution of phases, the associated volume changes and internal stresses, and ion and polysulfide diffusion within the battery.

Human induced pluripotent stem cells (hiPSCs) represent a promising cell source for generating functional cells suitable for clinical therapeutic applications, particularly in the context of autologous cell therapies. However, the production of hiPSCs through genetic manipulation, especially involving oncogenes, may raise safety concerns. Furthermore, the complexity and high costs associated with hiPSCs generation have hindered their broad clinical use.

4-(2-Aminoethyl)-benzenesulfonyl fluoride (AEBSF) is a serine protease inhibitor that may alleviate endoplasmic reticulum (ER) stress, a significant contributing factor to cerebral ischemia/reperfusion injury. The molecular crosstalk between ER stress, oxidative stress and autophagy represents a vicious cycle that can be pharmacologically targeted to minimize neuronal death after acute injuries to the central nervous system. However, the neuroprotective effects of AEBSF in the context of cerebral ischemia/reperfusion injury remain unknown.

Article Synopsis
  • High temperatures above 600 °C create challenges for metal lubrication due to softening and oxidation, making traditional lubricants ineffective.
  • Researchers found that additively-manufactured Inconel superalloy can achieve low coefficients of friction (COF) between 0.10-0.32 at temperatures reaching 900 °C by forming protective spinel-based oxide layers.
  • A computational approach was developed to predict the lubricating properties of different oxide compositions, highlighting the potential of spinel oxide for self-lubricating high-temperature alloys, outperforming traditional lubricants.

Chlorophenols (CPs) are widely used in industries such as petrochemicals, insecticides, pharmaceuticals, synthetic dyes and wood preservatives. However, owing to the improper discharge and disposal, they have become major contaminants that are ubiquitously distributed in water, soil, and sewage sediments, posing a significant threat to ecosystems and human health. Consequently, accurate, sensitive and effective pretreatment and analysis methods for CPs are urgently required and have been actively explored in recent years.

Background: Neuroimaging studies have shown that patients with mild traumatic brain injury (mTBI) often exhibit changes in gray matter volume (GMV) in the brain. However, the results regarding these changes are inconsistent, and the underlying molecular mechanisms remain unclear. This study aimed to investigate GMV changes in mTBI patients and uncover the molecular mechanisms driving these alterations.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are among the most prevalent complications associated with cardiac surgery involving extracorporeal circulation (ECC), contributing to adverse outcomes and representing a significant impediment to successful cardiac surgical procedures. Vascular endothelial growth factor (VEGF) is implicated in the etiology of ALI/ARDS; however, its precise role remains a subject of debate due to the presence of somewhat contradictory findings in the literature, necessitating further investigation. To date, numerous studies have explored the role of VEGF in the pathophysiology of ALI/ARDS, with ongoing discussions regarding whether VEGF exerts a protective or detrimental effect.

Intratumoral microbiota, which affects the physiological and pathological processes of the host, has attracted increasing attention from researchers. Microbials have been found in normal as well as tumor tissues that were originally thought to be sterile. Intratumoral microbiota is considered to play a significant role in the development of tumors and the reduction of clinical benefits.

  • - Sjögren's syndrome (SS) is a chronic autoimmune condition characterized by dry mouth and eyes due to the destruction of salivary and lacrimal glands, with potential systemic issues like pneumonia and nephritis.
  • - Current treatments mainly involve medications that manage inflammation but don't repair tissue, highlighting the need for innovative approaches like cell therapy.
  • - Cell therapy, which includes stem and immune cell therapy, shows promise in reducing inflammation and aiding tissue repair for SS, yet challenges remain in preparation and logistics of these therapies.

  • Traditional Chinese opera training involves complex skills and cultural knowledge, which may affect brain function; this study examined the neural impacts of such training on actors versus untrained individuals.
  • Twenty trained actors and twenty untrained subjects underwent resting-state fMRI scans to measure differences in brain activity and connectivity.
  • Results showed that actors had lower dALFF in a specific brain region and higher connectivity with other areas, suggesting that long-term training changes brain function; these findings point to a relationship between artistic practice and cognitive ability.
