Hematopoietic Stem Cell Transplantation in Vietnam： Current Status and Future Directions

引用

Journal of Pharmacy and Pharmacology 2018年第8期6卷 765-771页

作者： Phu Duc Vinh Huynh Man Van Huynh Nam Duy Hoang Ngon Thien Huynh Tuan Xuan Ma Thu Hanh nguyen Dung Chi Phu binh tan nguyen Blood Transfusion Hematology Hospital Hochiminh city700000 Vietnam University of Medicine and Pharmacy Hochiminh city 700000 Vietnam

In recent years, there have been an increasing number of hematologic patients in Vietnam. Hematopoietic stem cell transplantation （HSCT） is fast becoming an effective method to cure many benign and malignant blood disorders. Nine transplant centers are operating throughout Vietnam. HCMC Blood Transfusion Hematology Hospital （BTH） is one of these centers where bone marrow, peripheral blood and cord blood stem cell transplantation were first conducted in our country. At BTH, half of the patients received allogeneic HSCT, mainly from matched sibling donors due to lack of a national bone marrow donor registry. While acute myeloid leukemia was a common indication of allogeneic HSCT, most of the patients undergoing autologous HSCT had multiple myeloma. One major issue we encountered concerned bacterial and fungal infections during neutropenia period. Because of an endemic area, CMV reactivation frequently occurred. Five-year overall survival （OS） and event-free survival （EFS） were 47% and 46%, respectively. To create more opportunities for patients, our future directions will focus on some new transplant procedures, such as haploidentical, unrelated and cord blood transplantation.

Background In Viet Nam, tuberculosis (TB) represents a devastating life-event with an exorbitant price tag, partly due to lost income from daily directly observed therapy in public sector care. Thus, persons with TB may seek care in the private sector for its flexibility, convenience, and privacy. Our study aimed to measure income changes, costs and catastrophic cost incurrence among TB-affected households in the public and private *** Between October 2020 and March 2022, we conducted 110 longitudinal patient cost interviews, among 50 patients privately treated for TB and 60 TB patients treated by the National TB Program (NTP) in Ha Noi, Hai Phong and Ho Chi Minh City, Viet Nam. Using a local adaptation of the WHO TB patient cost survey tool, participants were interviewed during the intensive phase, continuation phase and post-treatment. We compared income levels, direct and indirect treatment costs, catastrophic costs using Wilcoxon rank-sum and chi-squared tests and associated risk factors between the two cohorts using multivariate *** The pre-treatment median monthly household income was significantly higher in the private sector versus NTP cohort (USD 868 vs USD 578;P=0.010). However, private sector treatment was also significantly costlier (USD 2075 vs USD 1313;P=0.005), driven by direct medical costs which were 4.6 times higher than costs reported by NTP participants (USD 754 vs USD 164;P<0.001). This resulted in no significant difference in catastrophic costs between the two cohorts (Private: 55% vs NTP: 52%;P=0.675). Factors associated with catastrophic cost included being a single-person household [adjusted odds ratio [(aOR=13.71; 95% confidence interval (CI): 1.36–138.14;P=0.026], unemployment during treatment (aOR=10.86; 95%CI: 2.64–44.60;P<0.001) and experiencing TB-related stigma (aOR=37.90; 95%CI: 1.72–831.73;P=0.021).Conclusions Persons with TB in Viet Nam face similarly high risk of catastrophic costs whether treated in the

Multilevel Threshold Based Image Denoising in Curvelet Domain

引用

Journal of Computer Science & Technology 2010年第3期25卷 632-640页

作者： nguyen Thanh binh Ashish Khare Department of Electronics and Communication University of Allahabad

In this paper, we propose a multilevel thresholding technique for noise removal in curvelet transform domain which uses cycle-spinning. Most of uncorrelated noise gets removed by thresholding curvelet coefficients at lowest level, while correlated noise gets removed by only a fraction at lower levels, so we used multilevel thresholding on curvelet coefficients. The threshold in the proposed method depends on the variance of curvelet coefficients, the mean and the median of absolute curvelet coefficients at a particular level which makes it adaptive in nature. Results obtained for 2-D images demonstrate an improved performance over other recent related methods available in literature.

New guidelines for fluorophore application in peroxisome targeting analyses in transient plant expression systems

引用

Journal of Integrative Plant Biology 2019年第7期61卷 884-899页

作者： Christian Falter nguyen binh Anh Thu Saugat Pokhrel Sigrun Reumann Plant Biochemistry and Infection Biology Institute of Plant Science and Microbiology University of Hamburg

Peroxisome research has been revolutionized by proteome studies combined with in vivo subcellular targeting analyses. Yellow and cyan fluorescent protein(YFP and CFP) are the classical fluorophores of plant peroxisome research. In the new transient expression system of Arabidopsis seedlings co-cultivated with Agrobacterium we detected the YFP fusion of one candidate protein in peroxisomes, but only upon co-transformation with the peroxisome marker, CFP-PTS1. The data suggested that the YFP fusion was directed to peroxisomes due to its weak heterodimerization ability with CFP-PTS1,allowing piggy-back import into peroxisomes. Indeed, if co-expressed with monomeric Cerulean-PTS1(mCer-PTS1),the YFP fusion was no longer matrix localized. We systematically investigated the occurrence and extent of dimerization-based piggy-back import for different fluorophore combinations in five major transient plant expression systems. In Arabidopsis seedlings and tobacco leaves both untagged YFP and monomeric Venus were imported into peroxisomes if co-expressed with CFP-PTS1 but not with mCer-PTS1. By contrast, piggy-back import of cytosolic proteins was not observed in Arabidopsis and tobacco protoplasts or in onion epidermal cells for any fluorophore combination at any time point. Based on these important results we formulate new guidelines for fluorophore usage and experimental design to guarantee reliable identification of novel plant peroxisomal proteins.

Carboxymethyl starch cross-linked by electron beam radiation in presence of acrylic acid sensitizer

引用

Nuclear Science and Techniques 2013年第B12期24卷 19-22页

作者： Doan binh nguyen Thanh Duoc Pham Thi Thu Hong R & D Center for Radiation Technology Vietnam Atomic Energy Institute 202A St. 11 Linh Xuan Ward Thu Duc District Ho Chi Minh City Vietnam

Carboxymethyl starch (CMS) can be cross-linked by electron beam radiation to form a biocompatible and environment-friendly hydrogel at a high absorbed dose and a condensed CMS concentration. Acrylic acid (AAc) can be used as a sensitizer in order to reduce the absorbed doses to an acceptable certain level. At an absorbed dose of 3?4 kGy, the gel content of crosslinked CMS can be obtained about 50% with 5% (w/w) AAc concentration used. The compressive strength of CMS samples increased with increasing their cross-linked densities due to raising absorbed doses. The swelling ratio of cross-linked CMS was also attainable at a maximum of 50 times in the distilled water. The enzymatic degradation of cross-linked CMS was carried out in acetate buffer pH 4.6 with 0.1% α-amylase enzymatic solution incubated at 40oC for 6 h. The crosslinked CMS samples were degraded slower than uncrosslinked CMS ones. The results indicated that the highly cross-linked CMS was almost fully degradable when the enzymatic hydrolysis was performed during 6 h. The FT IR spectra of cross-linked CMS in the presence of AAc were examined to observe the carboxyl group of AAc in the structure of cross-linked CMS. The hydrophilic of cross-linked CMS surface was determined by a contact-angle analysis.
