Chemical constituents of Euphorbia tirucalli L.
Tập 2 Số 5 - Trang 76-82 - 2019
This article was retracted on 15 December 2021 by authors.
Euphorbia tirucalli has not been chemically studied much in Vietnam. This research described the isolation and elucidation of compounds isolated from the plant collected in Binh Thuan. Multiple chromatographic methods were applied, including normal phase silica gel column chromatography and thin-layer chromatography. Seven compoun...... hiện toàn bộ
Application of MIKE 21 FM modelling to simulate the water quality at the coastal area Đình Vũ
Tập 1 Số T4 - Trang 282-292 - 2017
The MIKE 21 FM model, developed by the Danish Hydraulic Institute, is a distributed system model that is used in hydrological calculations, water quality simulation, sediment transport calculations, resources and water environment in rivers, estuaries, coastal areas, and seas... This paper is an initial step in setting and establishing a set of model's parameters for simulating contaminant transpo...... hiện toàn bộ
Inventory and mapping the air emissions from transportation activities in Ho Chi Minh city
Tập 3 Số 2 - Trang 100-114 - 2019
Ho Chi Minh City plays a role as a leading economic and social center in the South of Vietnam, together with the urbanization, transportation system is being rapidly developing, resulting in an increase in emissions from these activities, and worsen the quality of the city. Therefore in this study, emission inventory for transportation has been conducted using the EMISENS model and then using GIS ...... hiện toàn bộ
Petrographic characteristics and zircon UPb geochronology of granitogneiss rocks in the Chu Lai - Kham Duc area (Quang Nam province)
Tập 1 Số 6 - Trang 258-272 - 2018
The early Palaeozoic granitogneiss association in the Chu Lai - Kham Duc area (Quang Nam) is a large area of hundreds of km2, along southern of the East – West ductile deformation zones (Tam Ky – Phuoc Son fault zone), which is studied in detail in different geologic maps scales by the geologists, which is named Chu Lai complex. The five samples studied in detail are composed mainly of granitognei...... hiện toàn bộ
Synthesis and evaluation of biological activities of two belinostat analogs bearing fluorine at the CAP
Tập 7 Số 1 - Trang 2522-2531 - 2023
Histone deacetylase enzymes are overexpressed in many types of hematologic malignancies (acute myelogenous leukemia, myelofibrosis, cutaneous T-cell lymphoma, and Hodgkin lymphoma) and their inhibition of HDACs could result in the inhibition of cell proliferation and induction of apoptosis. Thus, HDAC inhibitors are candidates of anticancer drug development. Belinostat is a histone deacetylase inh...... hiện toàn bộ

Preparation of silica/carbon composite from rice husk and its electrochemical propertives as anode material in Li-ion batteries
Tập 4 Số 4 - Trang 767-775 - 2020
Rice husk is a common agricultural waste and an abundant source in Viet Nam. In terms of composition, rice husk is a silica-rich material (SiO2) so it can be used to prepare negative electrode materials for rechargeable Li-ion batteries. Recent processes of synthesizing the silica materials for the rechargeable batteries are often complex, expensive, and energy-intensive. In this study, KOH was us...... hiện toàn bộ

Optimization of protein extraction from green algae Chaetomorpha sp. by response surface methodology
Tập 3 Số 3 - Trang 136-143 - 2019
Green brackish algae Chaetomorpha sp. are easily found in shrimp ponds in Mekong Delta, Vietnam. They can also be co-cultured with shrimps in brackish water shrimp ponds to increase shrimp health and yield. Chaetomorpha sp. algae contain high amount of protein from 10 to 20% w/w db, including water soluble protein and alkaline-soluble protein with over 88% total protein. Dried material were used f...... hiện toàn bộ

Chemical constituents isolated from the whole plant of Solanum procumbens
Tập 2 Số 6 - Trang 134-138 - 2019
Solanum procumbens L. is a medicinal plant belonging to the Solanaceae family. In Vietnam, it is known as "Ca gai leo", and it cultivated in some tropical countries in China, Laos, Cambodia, and Vietnam. From the stem of the ethyl acetate extract of Solanum procumbens, we had isolated one anthraquinone (1), four polyphenols (2-5), and one indole (6). By spectroscopic methods as well as comparing w...... hiện toàn bộ

Study on adenosine loading capacity of porous nanosilica for application in drug delivery
Tập 5 Số 1 - Trang 933-941 - 2020
Mesoporous silica nanoparticles (MSNs) are used as drug delivery materials because of their outstanding features such as large surface area, easy synthesis and high biocompability. In this study, inorganic mesoporous nanosilica material, MCM-41, was synthesized by sol-gel hydrothermal method using tetraethyl orthosilicate precursor (TEOS). The material structure and composition were analyzed by X-...... hiện toàn bộ

Microplastic pollution in clam (Meretrix Lyrata Sowerby, 1851) at Mekong Delta river, Vietnam
Tập 5 Số 3 - Trang 1443-1454 - 2021
The problem of microplastic pollution (<5 mm) is becoming one of the biggest challenges facing countries. One of the problems is the export value of seafood products. Therefore, to assess the microplastic accumulation in clam (Meretrix lyrata), this study investigated the concentration of microplastics (MPs) in clam and their habitat in four clam culture beds (Tan Thanh, Ba Tri, Ganh Hao, and B...... hiện toàn bộ
