Cây thuốc lá chuyển gen mang cấu trúc RNAi kháng đồng thời hai loại virus gây bệnh khảm
- 2011
Tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV) is one of the most important viral pathogens capable of affecting to many plant species, such as tomato, potato, tobacco, peppe etc. In order to generate fransgenic tobacco plants resistant to both TMV and CMV, RNA interference (RNAi) technology hasbeen applied in this study. A multi-fragment of 625 bp - CPi (including ...... hiện toàn bộ

Diversity of endophytic fungi from medicinal plants Dysosma difformis (Hemsl & E.H. Wilson) T.H. Wang collected in Ha Giang and Lai Chau
Tập 21 Số 2 - Trang 365-373 - 2023
Plant endophytes are an interesting group of microorganisms that colonize the internal tissues of living plants and do not cause any disease symptoms in the host plant. It exists in different parts of plants, such as roots, leaves, and stems, and significantly affects the formation of metabolic products in plants by promoting the accumulation of important secondary metabolites. The present study f...... hiện toàn bộ
Structure and characterization of the ribosomal transcription units of small liver flukes, Opisthorchis viverrini, O. Felineus and Clonorchis sinensis
Tập 17 Số 3 - Trang 441-447 - 2019
Opisthorchiasis is a zoonotic parasitic infection caused by small liver fluke species, Opisthorchis viverrini,O. felineus and Clonorchis sinensis, in the family Opisthorchiidae. Vietnam has both species, of which C.sinensis is distributed in the northern and O. viverrini in the central provinces. In addition to the mitochondrialgenomes, the ribosomal DNA sequences (rDNA) of these species are highl...... hiện toàn bộ

Cytokine inhibitory activity of eurycomanone in RAW 264.7 cells stimulated with viral-mimicking poly (I:C)
Tập 21 Số 3 - Trang 435-441 - 2023
Poly (I:C) (Polyinosinic:polycytidylic acid) is a synthetic analog of double-stranded RNA binding toll-like receptor 3 (TLR3) and mimicking a virus infection in macrophage. Here, for the first time, we showed the inhibitory effects of eurycomanone on the production of IL-6, TNF-alpha and IL-10 of RAW 264.7 cells stimulated with poly (I:C). Eurycomanone inhibited production of pro-inflammatory cyto...... hiện toàn bộ
A study on genetic diversity of bagrid catfish (Hemibagrus guttatus Lacepede, 1803) using microsatellite markers
Tập 16 Số 1 - Trang 59-65 - 2018
Bagrid catfish (Hemibagrus guttatus Lacepede, 1803) is a wild species of high economic value in Northern Vietnam. Artificial reproduction of bagrid catfish requires sources of quality fingerlings in terms of genetics. In fact, bagrid catfish is endangered due to overhunting. Until now, studying on bagrid catfish was mainly focused on biology characterictics and artificial breeding. In this study, ...... hiện toàn bộ

Comparison of bacterial community structures in digestive tract between healthy and disease whiteleg shrimp (Litopenaeus vannamei) in Soc Trang, Vietnam
Tập 16 Số 3 - Trang 543-551 - 2018
Gut bacteria comprise a complex bacterial community related to many functions in a host. The stability of gut bacteria plays important models in the health and immunology of a host. Many studies on intestine bacteria constructed via cultivation and Denaturation Gradient Gel Electrophoresis (DDGE) methods have proved a limited efficiency. In order to tackle these drawbacks, the next generation sequ...... hiện toàn bộ

Study on creating the hybridoma for producing a monoclonal antibody that causes agglutination of the red blood cell B group
- 2017
ABO incompatibility is a potential lethal barrier in tranfusion therapy. ABO blood cell grouping for all of the donors and potential recipients is the unique way for ensuring the highest safety for potential recipients in blood transfusion. ABO blood cell grouping must be performed by both of the serum sample method and erythrocytes sample method. Nowadays, when applying the serum sample method, t...... hiện toàn bộ

Optimizing culture conditions of human umbilical cord mesenchymal stem cells (hUC-MSCs) by adjusting the volume of xeno-free supplement serum
Tập 21 Số 2 - Trang 235-241 - 2023
Mesenchymal stem cells (MSCs) have become an effective tool for treating immune-related diseases due to their multilineage potential and immunomodulatory capabilities. However, a high cell dose is frequently essential for stem cell infusion in clinical practice. Therefore, it is necessary to produce sufficient quantities of MSCs while ensuring cell quality for clinical application in humans. To be...... hiện toàn bộ
Purification and activity determination of recombinant human SUMO protease’s active region fused with thioredoxin
Tập 22 Số 1 - Trang 117-124 - 2024
SUMO (Small Ubiquitin-related Modifier) protease is widely used for recombinant protein expression, but obtaining the protein from derivative sources is challenging due to the degradation during extraction and high costs. In a previous report, we expressed the human SUMO protease’s active region (SENP2) fused with thioredoxin (Trx-SENP2) in E. coli BL21 (DE3). The recombinant fusion protein was so...... hiện toàn bộ

Impact of mutations on Omicron's spike protein: Insights from variants found in Vietnam
Tập 21 Số 4 - Trang 621-635 - 2023
The SARS-CoV-2 virus is the primary agent responsible for the ongoing COVID-19 pandemic, leading to the loss of millions of lives worldwide. In 2023, the COVID-19 pandemic's impact is primarily driven by the Omicron variant, which features many unique mutations compared to previously identified SARS-CoV-2 variants. Through analysis of the network of Omicron variants collected in Vietnam, we determ...... hiện toàn bộ
