Welfare impact of climate change on capture fisheries in Vietnam.

Fisheries are forecasted to shrink in the tropics due to climate change. In Vietnam, fisheries are a pro-poor economic sector and essential nutrition source; however, welfares of producers and consumers in the climate change context are not well understood. While most studies focus on the gains or losses of total products and revenues, this paper pays additional attention to the changes in surpluses of market players in the long run. A combination of the production function, demand and supply functions, and partial equilibrium analysis is employed to measure the production and welfare impacts based on time series data from 1976 to 2018 and a Vietnam household living standards survey in 2018. The results show that relative to the present, catch yield is likely to reduce 35%-45% by mid-century and 45%-80% by the end of the century. Consumers may lose their surplus of 7-9 billion USD (PPP, 2018) by 2035 and 10-18 billion USD by 2065 due to supply reduction, while producers may gain additional profit of 3.5-4.5 billion USD by 2035 and 5-9 billion USD by 2065 owing to a price increase. The research findings suggest that Vietnam could impose measures to limit capture effort, as set out in the Law of Fisheries 2017, without harming fisher welfare. The expansion of aquaculture could reduce the gap between supply and demand of wild fish to mitigate consumer welfare loss; however, this impact is still ambiguous.

Studying the changes of leukocyte, erythrocyte and bone-marrow of mice treated by gamma irradiation

Studying the effectiveness of irradiation on bone-marrow, the numbers of leukocyte, erythrocyte, hemoglobin of mice (25 normal mice and 35 mice treated by gamma irradiation with the dose of 600 rad/(100rad/day) (60 Co) showed that: Gamma irradiation reduced total of leucocytes, the number of different leucocytic (lymphocyte, granulocyte, mono and natural killer cells), the ratio of reticulocyte, number of mature erythrocyte and hemoglobin: Total of leucocytes (3,14 ± 1,58 in comparison with 13,45 ± 4,6); monocytes (0,05 ± 0,03 in comparison with 0,26 ± 0,13), lymphocytes (1,66 ± 0,36 in comparison with 6,34 ± 2,84). After gamma irradiation, the number of reticulocyte was 55%, mature erythrocyte was 73% and hemoglobin was 82%

Ratio of B virus infection in Muong minority pupils

115/400 Muong minority pupils of boarding school in Hoa Binh province, all studied subjects have 3 genarations of Muong minority (grandparents, parents and themshelves being Muong minority), from 15 to 19 years old. Using Sero check product of USA to examine the ratio of HBsAg. Results: 19.05% of the boys having HBsAg(+), 13.38% of the girls having HBsAg(+). So the ratio of HBsAg(+) in girls are lower than in boys but it is not significant. The ratio of HBsAg(+) at the age of 15 is 19.61%, the age of 16-17 is 14.74% and the age of 18-19 is 16.67%, there is not significant between groups

Circulating immune-complexes in acute leprosy, chronic hepatitis, pharynx cancer and acute myelogenous leukemia

20 patients with acute leprosy, 12 patients with chronic hepatitis, 34 patients with acute myelogenous leukemia, 48 patients with pharynx cancer. 31 normal healthy persons in the control group. Immune-complexes were fixed quantity by 2 methods: precipitating the immune-complexes with PEG having molecular weight 6.10¬3 and better method. Immune-complexes (+) were identified on acute leprosy, chronic hepatitis and acute diseases with the ratio of positive differences depending on disease, stage and the character of applying technique

Contribute to understand the effect of chemicals on immunological responding capacity of people having frequent and long contact

Study on 48 people, of whom 16 are male and 32 are female, from 23 to 44 years old. They were long exposed with poly-chemicals, such as organic and iso-organic acids: benzene, toluene and their coequals. The parameters have been used: phagocyte capablity and phagocyte index of neutrophils; E, rossett formed T cells. The results showed that: Phagocyte capability and phagocyte index of neutrophils decreased significantly comparing with control group (p<0.001)

Changes in erythrocyte, leucocyte and platelet in people having frequent contact with chemicals

In this study, 48 long-term exposed people with polychemicals (the male/female ratio is 1/3, the age from 23 to 44): such as organic and iso-organic acids: benzene, toluene and their coequals were investigated. 17 normal people not exposed with polychemicals as the control group. Results were shown following: quantity of erythrocyte was lower than control group but not significantly. Leucocytes especially neutrophils reduced significantly (p<0.001). 15/48 cases (30%) appereared lymphoblast. There is no difference in platelet between studied group and control group

To finish the technique of identificating HLA in nasopharyngeal carcinoma patients

By the technique of indirect immunofluoresceine using 18 diverse markers, in the hospital K- Ha Noi, study was performed to determine the capacity of foreign antigene expression of tumor cells in the cell surface making them identified by immunology system through HLA system on NPC < 75 years old age patients. This system played an essential role in the regulation and realization of immune response.

The effects of "DYI" on experimental Heterogenous skin graft and mixed lymphocytic culture of human

Heterogenous transplantation of skin was studied on two strains of mice BALB/C and Swiss.The subjects were divided into various groups :normal group, cyclophosphamid (CP) inhibited group, cyclosporin A (CPA) inhibited group, and the group processed with DY1. The onset of reject phenomenon of the graft and the completed reject of the graft in the groups of mice using CP, CPA and DY1 were more delayed in comparing with the controlled subjects. The cell numbers decreased and the percentage of transformed cells also decreased in all groups using CP, CPA and DY1

Immunosuppressed model for experimental mice by cyclophosphamid

Study on white mices with age of 6-8 weeks, 18-20g body weight. They were divided into 3 groups: group 1 (control group): 30 mices; group 2: mices were immunesuppressed by 200mg cyclophosphamid per one kilogram of body weight, being checked after 5 days of injection; and 300mg cyclophosphamid per one kilogram (200mg on the first day and 100mg on the fifth day) and it was checked after 10 days of injection (group 3). The results: immunesuppressed model implemented by intraperitonial injection of 200mg per one kilogram of body weight checked after 5 days of injeciton. These parameters were used to assign the immune function
