In Children, -Methyl-D-Aspartate Receptor Antibody Encephalitis Incidence Exceeds That of Japanese Encephalitis in Vietnam.

Background: The recognition of autoimmune causes of encephalitis has led to epidemiological shifts in the worldwide characteristics of encephalitis. -methyl-D-aspartate receptor (NMDAR) antibody encephalitis leads to well-established complex neuropsychiatric manifestations. In low- and middle-income countries, including Vietnam, its relative incidence, especially in children, is unknown and most neurologists currently consider infectious encephalitis prior to autoimmune etiologies.

A Cost of Illness Analysis of Children with Encephalitis Presenting to a Major Hospital in Vietnam.

Encephalitis is a significant global health problem, especially in children. Knowledge of its economic burden is essential for policymakers in prioritizing the development and implementation of interventions but remains limited. An observational study was prospectively conducted at a major children's hospital in Ho Chi Minh City, Vietnam from 2020 to 2022.

A new iridoid glucoside from the roots of .

A new iridoid glucoside, moridoside (), and nine known compounds, asperulosidic acid (), 6---acetylscandoside (), geniposidic acid (), 2-hydroxymethylanthraquinone (), 2-hydroxymethyl-3-hydroxyanthraquinone (), damnacanthol (), lucidine-ω-methyl ether (), 2-hydroxy-1-methoxyanthraquinone (), and 3,8-dihydroxy-1,2-dimethoxyanthraquinone () were isolated from the methanol extract of How. roots. Their structural identification was carried out based on the spectroscopic evidence.

Roles of β-Indole Acetic Acid (IAA) Producing Endophytic Bacteria on the Recovery of Plant Growth and Survival Ability of Sugarcane Infected White Leaf Disease (SWLD).

β-Indole acetic acid is produced in the rhizosphere by endophytic bacteria and promotes plant growth. Effects of bacterial IAA producers (BIPs) on plant growth and recovery of sugarcane seedlings infected with phytoplasma causing white leaf disease (SWLD) were examined. Fifty-five endophytic bacteria isolated from rice roots were collected from the Mekong River Delta, Vietnam.

Labdane-type diterpenoids from Vitex limonifolia and their antivirus activities.

Phytochemical investigation of the methanol extract of Vitex limonifolia leaves led to the isolation of three new labdane-type diterpenoids, vitexlimolides A-C (1-3) and eight known compounds, 5,4'-dihydroxy-3,7-dimethoxyflavone (4), vitecetin (5), 5,4'-dihydroxy-7,3'-dimethoxyflavone (6), verrucosin (7), 2α, 3α-dihydroxy-urs-12-en-28-oic acid (8), euscaphlic acid (9), 18,19-seco, 2α, 3α-dihydroxy-19-oxo-urs-11,13(18)-dien-28-oic acid (10), and maslinic acid (11). Their chemical structures were elucidated by physical and chemical methods. All compounds were evaluated for antiviral activities against CVB3, HRV1B, and EV71 viruses.

Mixed-signal template-based reduction scheme for stimulus artifact removal in electrical stimulation.

Simultaneous electrical stimulation and recording are used to gain insights into the function of neuronal circuitry. However, artifacts produced by the electrical stimulation pulses prevent the recording of neural responses during, and a short period after, the stimulation duration. In this work, we describe a mixed-signal recording topology with template subtraction for removing the artifact during the stimulation pulse.
