Background: many studies showed that obesity rate was significantly higher in women than in men and 60-80% of overweight/obesity caused by diet. Hanoi and Ho Chi Minh City were two of 10 provinces that had the highest rates of obesity. Objectives: to determine the actual rate of overweight/obesity and describe some related factors among Hanoians aged 50-59. Subjectives and Method: a cross sectional survey within a case-control study. The study was carried out in 14 wards under 7 districts of urban Hanoi. Body fat percentage was measured by machine Omron (Japan). Overweight/obesity evaluations were based on classification scales of WHO 1998 and IDI&WPRO 2000. Results: the mean rate of overweight/obesity was 23.1% (26.2% in women vs. 21.9% in men). The rate of women with waist to hip ratio >0.85 (39.83%) was higher than that in male (29.38%). Proportions of body fat percentage greater than 30% were 58.40% in female and 40.06% in male. Overweight/obesity was closely related with sedentary lifestyle, such as spending less time for exercise and sports, high food expenditures, etc. It was found that people with overweight or obese family members were 3 times at risk of overweight/obesity higher /than others. That rates of overweight/obese people with elevated level of biomarkers were composed of 48.99% with high blood cholesterol (>5.2mmol/l); 9.69% with blood glucose (\ufffd?.0mmol/l); especially 65.33% with high triglyceride (>1.7mmol/l); 7.22% with low HDL-C (<1.15 mmol/l); and 8.23% with high LDL-C (\ufffd?.00mmol/l). Conclusions: rate of overweight/obesity among Hanoians aged 50-59 was relatively high. Some related factors were described: waist to hip ratio, body fat percentage, sedentary lifestyle, such as spending less time for exercise and sports, high food expenditures, etc.

Mycobiology 2011;39(1):20-25
Spores of Aspergillus sp. SU14 were treated repeatedly and sequentially with Co60 gamma-rays, ultraviolet irradiation, and N-methyl-N'-nitro-N-nitrosoguanidine. One selected mutant strain, Aspergillus sp. SU14-M15, produced cellulase in a yield 2.2-fold exceeding that of the wild type. Optimal conditions for the production of cellulase by the mutant fungal strain using solid-state fermentation were examined. The medium consisted of wheat-bran supplemented with 1% (w/w) urea or NH4Cl, 1% (w/w) rice starch, 2.5 mM MgCl2, and 0.05% (v/w) Tween 80. Optimal moisture content and initial pH was 50% (v/w) and 3.5, respectively, and optimal aeration area was 3/100 (inoculated wheat bran/container). The medium was inoculated with 25% 48 hr seeding culture and fermented at 35degrees C for 3 days. The resulting cellulase yield was 8.5-fold more than that of the wild type strain grown on the basal wheat bran medium.

Mycobiology 2009;37(4):267-271
A fungal strain producing a high level of cellulase was selected from 320 fungal isolates and identified as Aspergillus sp. This strain was further improved for cellulase production by sequential treatments by two repeated rounds of gamma-irradiation of Co60, ultraviolet treatment and four repeated rounds of treatment with N-methyl-N'-nitro-N-nitrosoguanidine. The best mutant strain, Aspergillus sp. XTG-4, was selected after screening and the activities of carboxymethyl cellulase, filter paper cellulase and beta-glucosidase of the cellulase were improved by 2.03-, 3.20-, and 1.80-fold, respectively, when compared to the wild type strain. After being subcultured 19 times, the enzyme production of the mutant Aspergillus sp. XTG-4s was stable.
