1.Study on the influence of yeast containing selenium on the constitution and hemopoietic system of experimental animals
Pharmaceutical Journal 2002;310(2):21-23
The dried yeast- bioselen containing 500g selenium/g was used in this study. Rabbits received yeast solution containing selenium with doses of 20 and 40g/kg b.w. per os daily in a course of 30 days consecutive. The experimental results showed that this solution containing selenium did not change significantly common status, the bodyweight and blood forming functions in comparison with control group which received the solvent only

Background: DNA biosensor is based on micro-nano technologies aimed at developing a rapid diagnostic device of infectious diseases and diseases related to genetic change. Biosensors are compact size, high sensitivity and low cost\r\n', u'Objectives: To evaluate effect of biosensor in detecting specific gene fragments of Herpes Simplex virus type 1 and 2 (HSV)\r\n', u'Subjects and method: The electrical signals were recognized by means of transducer and from electrochemical detection of the hybridization between the probe 5\ufffd?AT CAC CGA CCC GGA GAG GGA C-3\ufffd?which were covalently immobilised onto the surface of micro electrodessensors in 3-aminopropyltri-ethoxysilance (APTS)-the conducting polymer matrix and the target (specific DNA sequences of HSV in the sample.\r\n', u'Results: The DNA sensor offers a very high sensitivity, a fast response time, less than 1 min with the DNA target concentration up to 1nM in aqueous media at room temperature.However, in order to detect target DNA in the real samples, samples must be extracted DNA, denatured DNA sequences from a double fiber to single fiber. The measurement should be done soon\r\n', u'Conclusion: The results show a large promise to develop quickly DNA sensors for widely application in bio-medical research \r\n', u'\r\n', u'

Objective:
To document the evolution and optimization of the Zika virus (ZIKV) disease surveillance system in southern Viet Nam in 2016 and to describe the characteristics of the identified ZIKV-positive cases.
Methods:
We established a sentinel surveillance system to monitor ZIKV transmission in eight sites in eight provinces and expanded the system to 71 sites in 20 provinces in southern Viet Nam in 2016. Blood and urine samples from patients who met the case definition at the sentinel sites were tested for ZIKV using real-time reverse transcription polymerase chain reaction at the Pasteur Institute in Ho Chi Minh City (PI-HCMC). We conducted descriptive analysis and mapped the ZIKV-positive cases.
Results:
In 2016, 2190 specimens from 20 provinces in southern Viet Nam were tested for ZIKV at PI-HCMC; 626 (28.6%), 484 (22.1%), 35 (1.6%) and 1045 (47.7%) tests were conducted in the first, second, third and fourth quarters of the year, respectively. Of these tested specimens, 214 (9.8%) were ZIKV positive with 212 (99.1%) identified in the fourth quarter. In the fourth quarter, the highest positivity rate was those in age groups 30–39 years (30.0%) and 40–59 years (31.6%). Of the 214 ZIKV-positive patients, 210 (98.1%) presented with rash, 194 (90.7%) with fever, 149 (69.6%) with muscle pain, 123 (57.5%) with joint pain and 66 (30.8%) with conjunctivitis.
Discussion
The surveillance system for ZIKV disease underwent several phases of optimization in 2016, guided by the most up-to-date local data. Here we demonstrate an adaptable surveillance system that detected ZIKV-positive cases in southern Viet Nam.
