Effects of dioxin exposure on reproductive and thyroid hormone levels and male sexual function in airbase military workers in Vietnam.

Dioxins are endocrine disruptors that may disturb male sexual and reproductive function. Studies on human populations are limited, and their results are controversial. This study evaluated the impact of dioxin exposure on reproductive and thyroid hormone levels and sexual function in men.

Chromium, Cadmium, Lead, and Arsenic Concentrations in Water, Vegetables, and Seafood Consumed in a Coastal Area in Northern Vietnam.

Background: Heavy metal contamination and related risks for the environment and human health are matters of increasing concern.

Methods: The levels of 4 heavy metals (Cr, Cd, Pb, and As) were evaluated in 2 water types (surface and well), 4 types of seafood (tiger shrimp, stuffed snail, snake-head fish, and catfish), and 27 types of vegetables (12 leafy vegetables, 4 pea plants, 4 tuber vegetables, and 7 herbs) that are commonly consumed in northern coastal communes located in Vietnam. Atomic absorption spectrometry was employed for quantification.

Flavonol glycosides from .

Two new flavonol glycosides, fissmacosides A (1) and B (2) along with two known flavonol glycosides, kaempferol 3--l-rhamnopyranosyl-(1→6)--d-galactopyranoside (3) and kaempferol 3--d-glucopyranosyl-(1→4)--l-rhamnopyranosyl-(1→6)-[4-()-feruloyl]--d-galactopyranoside (4) were isolated from the methanol extract of the leaves of Merr. Their structures were determined on the basis of extensive spectroscopic methods, including 1D-, 2D-NMR, and MS data.

Prevalence and correlates of multimorbidity among adults in border areas of the Central Highland Region of Vietnam, 2017.

Introduction: The objectives of this study are to estimate the prevalence of multimorbidity (MM) among adults in the Central Highland Region (a poor region) of Vietnam in 2017 and to identify the sociodemographic correlates of these conditions.

Methods: We used data from a cross-sectional study conducted in 2018 on health status among people in four provinces in the Central Highlands Region (Tay Nguyen) of Vietnam. A sample of 1680 adults (aged 15 years and older) were randomly selected for this study.

Protective and anticataract effects of the aqueous extract of Cleistocalyx operculatus flower buds on beta-cells of streptozotocin-diabetic rats.

The aim of the present study was to examine whether an aqueous extract of Cleistocalyx operculatus flower buds (COB) had protective and anticataract effects on beta-cells in experimental streptozotocin (STZ)-induced diabetes in rats. After 9 weeks of COB supplementation (500 mg/kg bw), the COB group had a significantly more stable insulin level as compared with the control diabetic group. Increased staining of insulin and preservation of islet cells were apparent in the COB-treated diabetic rats, whereas islet cell degeneration and weak insulin immunohistochemical staining were observed in the control diabetic rats.

Effects of salt concentration on the reaction rate of Glc with amino acids, peptides, and proteins.

The reaction between the amino group and the carbonyl group is important in food quality control. Furthermore, advanced glycation end products from foods are considered to relate to aging and diabetes. Thus, it is important to control this reaction.

Anti-hyperglycemic activity of an aqueous extract from flower buds of Cleistocalyx operculatus (Roxb.) Merr and Perry.

A screening of 5 plants used for making drinks in Vietnam revealed a Cleistocalyx operculatus (Roxb.) Merr and Perry flower bud extract to have the highest inhibitory activity against the alpha-glucosidase enzyme. The anti-hyperglycemic effects of an aqueous extract from flower buds of Cleistocalyx operculatus (CO), a commonly used material for drink preparation in Vietnam, were therefore investigated in vitro and in vivo.

Toxicity of the AGEs generated from the Maillard reaction: on the relationship of food-AGEs and biological-AGEs.

Advanced glycation end products (AGEs) are generated in the late stages of Maillard reaction in foods and biological systems. These products are mostly formed by the reactions of reducing sugar or degradation products of carbohydrates, lipids, and ascorbic acid. AGEs exist in high concentration in foods, but in relatively low concentrations in most of the biological systems.

Plasma triglyceride and HDL-cholesterol concentrations in Vietnamese girls are affected by lipoprotein lipase, but not apolipoprotein CIII polymorphism.

Lipoprotein lipase (LPL) and apolipoprotein CIII (apoCIII) play an important role in HDL-cholesterol and triglyceride metabolism. This study examined the effects of LPL S447X and apoCIII SstI polymorphisms on the plasma lipid and lipoprotein concentrations in Vietnamese girls. Three hundred and fifty-one Vietnamese girls, from 7 to 9 y of age, were randomly selected from the urban and rural areas of Ho Chi Minh City, Vietnam.

Inhibition of tumor growth and angiogenesis by water extract of Gac fruit (Momordica cochinchinensis Spreng).

The antitumor activity of the crude water extract from Gac fruit (Momordica cochinchinensis) was investigated in vivo and in vitro. A water extract prepared from 0.75 and 0.

Comparison of ingestive effects of brewer's yeast, casein, and soy protein on bioavailability of dietary iron.

The effects of brewer's yeast, casein, and soy protein intakes on the absorption and retention as well as the incorporation into hemoglobin and systemic iron stores of dietary iron were examined in an animal experiment with growing rats. Relative biological values (RBV) of iron in the rats fed casein (C), soy protein (SP), and yeast (Y) diets were 1.00, 0.

Simultaneous analysis of retinol, beta-carotene and tocopherol levels in serum of Vietnamese populations with different incomes.

In this study, we clarified the status of the fat-soluble vitamins retinol and tocopherol, as well as beta-carotene, as antioxidants in the prevention of cardiovascular disease in middle-aged Vietnamese populations with different incomes. In order to measure simultaneously the serum concentrations of retinol, beta-carotene and tocopherol, we carried out high-performance liquid chromatography analysis with three separate detectors. The analytical method was modified, omitting the saponification process, and used a multi-evaporating system with dry ice.

Serum fatty acids, lipoprotein (a) and apolipoprotein profiles of middle-aged men and women in South Vietnam.

In Vietnam, increasing fat consumption is a trend recognized recently in urban areas. To obtain a reasonable nutrition status and prevent cardiovascular disease (CVD), it is necessary to obtain information on habitual fat intake and biochemical parameters as risk factors for CVD in Vietnamese populations. Therefore, from the analysis of serum fatty acid composition, fat consumption patterns in Vietnamese populations in South Vietnam, with different incomes, are discussed in this study.
