Chemical Composition Analysis and Antioxidant Activity of Monofloral Honeys from Vietnam.

Monofloral honey samples () from Vietnam were determined for their chemical compositions. This is the first report on the chemical composition and antioxidant activity of coffee honey from Vietnam. These samples were characterized by their high contents of total and reducing sugars, total phenolic contents, and total flavonoid contents.

Secondary metabolites from a peanut-associated fungus IMBC-NMTP01 with cytotoxic, anti-inflammatory, and antimicrobial activities.

Chemical investigation of a peanut-associated fungal strain IMBC-NMTP01 resulted in isolation and identification of 14 secondary metabolites, including two new, -aspergillusol () and aspernigin (), and 12 known compounds: pyrophen (), 2-(hydroxyimino)-3-(4-hydroxyphenyl)propanoic acid (), aspergillusol A (), rubrofusarin B (), nigerasperone A (), fonsecin (), TMC-256C1 (), pyranonigrin A (), orlandin (), nigerasperone C (), asperpyrone A (), and 5-(hydroxymethyl)-2-furancarboxylic acid (). Compounds , showed cytotoxicity toward all six human cancer cell lines, including HepG2, KB, HL-60, MCF-7, SK-Mel2, and LNCaP, with IC values ranging from 8.4 to 84.

Factors associated with antenatal depression among pregnant women in Vietnam: A multisite cross-sectional survey.

This study aimed to describe the status of antenatal depression and its associated factors among pregnant women in Vietnam. A cross-sectional study was conducted in four obstetric hospitals in Vietnam from January to September 2019. A total of 1260 pregnant women were interviewed using a structured questionnaire.

Nutritional status and postoperative outcomes in patients with gastrointestinal cancer in Vietnam: a retrospective cohort study.

Background: Nutritional support for surgical care is crucial because hospital malnutrition is rather common. However, low- and middle-income countries have not adequately addressed nutritional management of surgical patients. To highlight need for nutritional management in surgical patients, the present study aimed to describe preoperative nutritional status in patients who underwent gastrointestinal cancer surgery in Vietnam and to investigate the relationship between preoperative malnutrition and adverse outcomes, such as postoperative complications and prolonged length of hospital stay.

Magnetic chitosan nanoparticles for removal of Cr(VI) from aqueous solution.

A simple method was introduced to prepare magnetic chitosan nanoparticles by co-precipitation via epichlorohydrin cross-linking reaction. The average size of magnetic chitosan nanoparticles is estimated at ca. 30 nm.

Identification of Anopheles minimus complex and related species in Vietnam.

Anopheles minimus A and C and several closely related species of mosquitoes have been identified in Vietnam, where some have been implicated in malaria transmission. Morphological variation within and between Anopheles minimus A and C makes identification using alpha taxonomy difficult and several molecular techniques have been developed to separate them. However the difficulties of applying these techniques and the benefits of morphological identification in the field have seen morphological characteristics, such as the humeral pale spot on the costa, being used to separate these two species.

Amino acid mutations in Plasmodium vivax DHFR and DHPS from several geographical regions and susceptibility to antifolate drugs.

The increasing use of sulfadoxine-pyrimethamine (SP) for the treatment of chloroquine-resistant Plasmodium falciparum has resulted in increased reports of SP resistance of P. falciparum worldwide. Selection of SP-resistant Plasmodium vivax in areas where P.

Effects of Acipimox on the metabolism of free fatty acids and very low lipoprotein triglyceride.

The mechanism of triglyceride lowering by Acipimox, a nicotine acid analogue, was examined in a group of five moderately hypertriglyceridemic male rhesus monkeys. Two experiments were designed to examine the effect of the drug on lipid and glucose metabolism in nondiabetic, insulin-resistant animals. A single dose of Acipimox (8 mg/kg) given with a meal lowered the plasma free fatty acids (FFA) significantly at 4 h (0.

The evaluation of corneal endothelial permeability in PERK study patients.

Sixteen patients enrolled in the PERK study were evaluated by fluorophotometry 24 hours or six months following radial keratotomy. A comparison of eyes operated and not operated upon showed that endothelial permeability was not significantly altered 24 hours and six months after surgery. Aqueous humour flow rates and anterior chamber elimination coefficients were significantly higher 24 hours after surgery in the eyes operated on than in those not operated on.
