Neuroprotective Effects of Ethanol Extract (EEPG) Against Glutamate Induced Neurotoxicity in HT22 Cells.

Oxidative stress induced by glutamate is a significant contributor to neuronal cell damage and can lead to neurodegenerative diseases such as Alzheimer's, Huntington's, and ischemic brain injury. At the cellular level, oxidative stress increases Ca ion influx and reactive oxygen species (ROS), which activate the MAPK signaling pathway. Additionally, the generation of ROS causes mitochondrial dysfunction, triggering apoptosis by promoting the translocation of AIF to the nucleus from the mitochondria.

Hypothetical acceptability of minimally invasive tissue sampling and considerations for practice: A qualitative study in Vietnam.

The exact aetiology of the cause of death (COD) remains unknown for a high proportion of deaths caused by infectious diseases. Complete diagnostic autopsy (CDA) is considered the gold standard to determine COD, but it is often not used in low and middle-income countries (LMIC), including Vietnam, for a variety of reasons. One alternative is minimally invasive tissue sampling (MITS).

Understanding Acceptability and Willingness-to-pay for a C-reactive Protein Point-of-care Testing Service to Improve Antibiotic Dispensing for Respiratory Infections in Vietnamese Pharmacies: A Mixed-methods Study.

Background: Pharmacies are popular first points of contact for mild infections in the community. Pharmacy services in many countries have expanded to include vaccines and point-of-care tests. In low- and middle-income countries such as Vietnam, poor enforcement of regulations results in substantial volumes of over-the-counter antibiotic sales.

Deciphering the actin structure-dependent preferential cooperative binding of cofilin.

The mechanism underlying the preferential and cooperative binding of cofilin and the expansion of clusters toward the pointed-end side of actin filaments remains poorly understood. To address this, we conducted a principal component analysis based on available filamentous actin (F-actin) and C-actin (cofilins were excluded from cofilactin) structures and compared to monomeric G-actin. The results strongly suggest that C-actin, rather than F-ADP-actin, represented the favourable structure for binding preference of cofilin.

This study explored the fungal compositions and the potential of fungal taxa as bioindicators for indicating the water quality of the Mekong River, as the use of fungal indicators of the Mekong River was not previously well characterized. The Mekong River exhibited dynamic variations in both physicochemical/hydrochemical properties and fungal communities according to seasons and locations.

On the division of labor in the maintenance of intersubjectivity: insights from the study of other-initiated repair in Vietnamese.

Few ideas have figured more centrally in the history of social theory than that of the division of labor. Here we ask whether conversational interaction, like other forms of social activity, exhibits a division of labor and, if so, what functions this serves and how it might be understood in relation to the theories of Marx and Durkheim. We begin by noting that, though conversational participants actively work to achieve and sustain understanding, much of the time this work is invisible and only its products are displayed in the form of sequentially fitted next turns at talk.

Scalable and Consolidated Microbial Platform for Rare Earth Element Leaching and Recovery from Waste Sources.

Chemical methods for the extraction and refinement of technologically critical rare earth elements (REEs) are energy-intensive, hazardous, and environmentally destructive. Current biobased extraction systems rely on extremophilic organisms and generate many of the same detrimental effects as chemical methodologies. The mesophilic methylotrophic bacterium AM1 was previously shown to grow using electronic waste by naturally acquiring REEs to power methanol metabolism.

The effects of pretreatment with Cyclosporin A and Docetaxel before vitrification of porcine immature oocytes on subsequent embryo development.

In the present study, we attempted to improve the developmental competence of vitrified immature porcine oocytes by the preservation of mitochondrial properties using Cyclosporin A (CsA, inhibitor of mitochondrial membrane permeability transition) and Docetaxel (stabilizer of microtubules, hence mitochondrial distribution). In Experiment 1, Mitotracker red staining revealed reduced mitochondrial activity (MA) in vitrified/warmed oocytes at 0 and 22 h of in vitro maturation (IVM) compared with fresh ones. However, by at 46 h of IVM, MA levels in vitrified oocytes were similar to those in fresh control.
