Traumas at skull and/or facial bones (skull traumas for short) often impact seriously to the health of patients. Among all kinds of injuries caused by traffic accidents in Vietnam, the percentage of this sickness type is not small. To

The focus is a case study of software offshore outsourcing from Japan to Vietnam. Initial results confirm that willingness to cooperate and good impressions facilitate the knowledge transfer process. In addition, communication barriers, cultural differences, lack of equivalence in individual competence, and lack of common rules slow down the transfer

E-waste scrap generated in Asia is recycled in China, especially in Guangdong Province. The informal sector in that province has been recycling E-waste scrap and its improper recycling methods have caused serious pollution. In response to this problem, there is wide support for

This article presents the first estimations of burden of disease in Vietnam in 2008 using disability-adjusted life years (DALYs). DALYs were calculated using the Global Burden of Disease (GBD) methods. Incidence, prevalence of diseases, and causes of death was extracted from Vietnam data. Disability weights were borrowed from GBD and Dutch research. In 2008, the total burden of disease in Vietnam was 12.3 million DALYs. Noncommunicable diseases dominated the total burden of diseases in Vietnam, accounting for 71% of the total burden, and cardiovascular disease was the leading cause group of premature death. While pneumonia was an important cause of burden in Vietnamese children, stroke and depression were the main causes of disease burden among adults. The study provides a snapshot of Vietnamese health status and offers guidance for health policymaking in Vietnam.

In this study, a distributed flood modelling approach, WetSpa, was performed by modifying model representations of some of the predominant features and processes

Most cases are not treated and progress to end-stage renal disease (ESRD) with an increased risk for cardiovascular complications. Renal replacement therapies are so expensive that most ESRD patients die without treatment. Thus, countermeasures against early stages of CKD are urgently needed. Nevertheless, basic information for CKD has not been reported in Vietnam. We conducted a survey of CKD in 8,505 inhabitants aged >40 years in Vietnam. Subjects with abnormal urinary findings were further examined, including serum creatinine levels. In this study, CKD was defined as…

Intraperitoneal (IP) or intracerebroventricular (ICV) injection of majonoside-R2 (3.1-6.2 mg/kg, IP or 5-10 micrograms/mouse, ICV) and diazepam (0.1-0.5 mg/kg, IP or 0.5-1.0 microgram/mouse, ICV), as well as an opioid receptor antagonist naloxone (2 mg/kg, IP or 5 micrograms/mouse, ICV), dose-dependently attenuated the antinociception caused by subcutaneously administered morphine and U-50,488H. Moreover, when co-administered ICV or intrathecally (IT) with morphine (4 micrograms/mouse) or U-50,488H (60 micrograms/mouse), majonoside-R2 (5-20 micrograms/mouse) also exhibited antagonism against the antinociceptive action of these opioid receptor agonists in the tail-pinch test. The inhibitory effects of majonoside-R2 (10 micrograms/mouse, ICV) and diazepam (1 microgram/mouse, ICV) were reversed by flumazenil (2.5 micrograms/mouse, ICV), a selective benzodiazepine receptor antagonist, and picrotoxin (0.25 microgram/mouse, ICV), a GABA-gated chloride channel blocker. These results suggest that majonoside-R2 attenuates the opioid-induced antinociception by acting at the spinal and supraspinal levels, and that the GABAA receptor complex at the supraspinal level is involved in the effect of ICV administered majonoside-R2.

The records of all 152 hospitalized children with chronic kidney disease in the National Paediatric Hospital in Hanoi from January 2001 to December 2005 were analyzed. The incidence of paediatric chronic kidney disease native to Hanoi City was estimated to be 5.1/million-child population (pmcp). Median age was 11.29 years; 60.5% were boys and 39.5% were girls; 65% of patients were in end-stage renal disease. Causes of chronic kidney disease included glomerulonephritis (66.4%) and congenital/hereditary anomalies (13%). In 19.8% of children, the aetiology was unavailable. During hospitalization, five patients died and 76 patients (50%) refused the treatment although beneficiaries of health insurance. Thirty patients (19.74%) received peritoneal dialysis and haemodialysis, and seven patients received renal transplantation with a familial living donor. Late referral, and limited facilities for renal replacement therapy explain the poor outcome in this study. We need a program to delineate the burden of chronic kidney disease and improve primary health care for health promotion and prevention of paediatric chronic kidney disease.

(Acanthaceae) is a wild growing and cultivated plant used for dyeing of foods by the ethnic minorities of Vietnam. The major component of the colour aqueous extract (CAE) of its leaves was identified as peristrophine by spectral analysis, especially the 2D NMR spectra (HSQC, HMBC and NOESY). Considering the widespread utilisation of the decoction of this plant for food dyeing, we evaluated the acute oral toxicity of the CAE. Based on the results in an acute toxicity study in mice, the LD50 value of the CAE was determined as 9100 ± 290 mg kg(-1) body weight. Additionally, in vitro cytotoxic assay showed an inhibition of peristrophine against Hepatocellular carcinoma (HepG2, IC503.90 µg mL(-1)). CAE and peristrophine (1) have also been tested for their ability to affect the cell number of the OCI acute myeloid leukaemia cell line. CAE and peristrophine significantly decreased the OCI cell number at different concentrations and times of treatment.
