1Production of asiaticoside from centella(Centella asiatica L.Urban)cells in bioreactor显示文摘Objective:To investigate the effects of some culture conditions on production of asialicoside from centella(Centella asiatica L.Urban)cells cultured in 5-L bioreactor.Methods:The centell cell suspension culture was conducted in 5-L bioreactor to investigate the growth and asiaticoside accumulation under various conditions.Asiaticoside content was determined by HPLC analysis.Results:The results showed that the cell growth and asiaticoside accumulation peaked after 24d of culture at an agitation speed of 150 r/min and aeration rate of 2.5 L/min.The cell biomass reached a maximum value of 302.45 g fresh weight(31.43 g dry weight)and growth index of 3.03with inoculum size of 100 g.However,asiaticoside content was the highest(60.08 mg/g dry weight)when culture was initiated with an inoculum size of 50 g.Conclusions:The present study found the suitable conditions for growth of centella cells and their asiaticoside production in bioreactor.Nguyen Hoang Loc Nguyen Thi Duy Nhat 2013Asian Pacific Journal of Tropical Biomedicine2013,3,10:2

4Antibiotic usage in surgical sperm retrievals among IVF centers显示文摘Surgical sperm retrieval(SSR)is currently one of the most common procedures in in vitro fertilization(IVF).However,a gap between the guidelines and routine clinical practice regarding antibiotic use in sSR,which might lead to antibiotic resistance,is a challenging problem worldwide.A cross-sectional survey was conducted from May 1,2021,to July 15,2021,to investigate antibiotic usage by medical professionals when performing SSR in IVF centers in Vietnam.The confidential questionnaire comprised 12 items,including characteristics of the study population,awareness of antimicrobial resistance,attitude toward prescribing antibiotics,and current practice of prescribing antibiotics when performing SSR.Surveys were completed by 30 of 45 registered IVF centers(66.7%).Among 67 physicians working at those centers,the age and work-experience years(mean±standard deviation[s.d.])were 38.6±6.6 years and 11.2±7.0 years,respectively.Over 60%of them held a degree in Obstetrics and Gynecology,and over four-fifths were men.Most respondents'often/very often/always'raised awareness of antimicrobial resistance to their patients(83.3%),but only half of them'often/occasionally'prescribed antibiotics to patients with SSR in cases where the prescription would be optional.About one-tenth of respondents followed the recommendation from the American Urological Association using'prophylaxis only'for SSR patients.For more invasive SSR,physicians tended to prescribe more complicated and sometimes inappropriate regimens.In conclusion,antibiotic usage in SSR was not always appropriate among IVF centers.Further studies may define specific recommendations for regimens,intervention strategies,and programs to promote appropriate antibiotic use for SSR patients among IVF specialists.Le Dang Khoa Ngo Dinh Trieu Vy Nguyen Minh Tai Loc Le Duc Thang Dang Tuan Anh Nguyen Phuc Hieu Giang Huynh Nhu Nguyen Dinh Tao Le Hoang David J Handelsman 2022Asian Journal of Andrology2022,24,6:0
