Thành phần tinh dầu từ rễ Siliquamomum tonkinense Baill. thu thập ở Vườn Quốc gia Tam Đảo, tỉnh Vĩnh Phúc Dịch bởi AI
Academia Journal of Biology - - 2015
Chi Siliquamomum Baill. chỉ bao gồm hai loài, đó là Siliquamomum tonkinense Baill. và Siliquamomum oreodoxa N.S. Glass & Skornick. Loài S. tonkinense đã được sử dụng như một cây thuốc truyền thống để điều trị đau dạ dày, chảy máu dạ dày hoặc tắm thuốc cho phụ nữ sau khi sinh. Tinh dầu từ rễ S. tonkinense được thu thập ở Vườn Quốc gia Tam Đảo, tỉnh Vĩnh Phúc (Việt Nam) được chiết xuất bằng phươ......

Phylogenetic relationships of \(\textit{Quercus}\) species (Fagaceae) in Vietnam based on multiplexed inter simple sequence repeat genotyping by sequencing
Academia Journal of Biology - Tập 46 Số 1 - Trang 99-108 - 2024
Quercus is the largest genus of the family Fagaceae in the world and the second-largest in Vietnam, with approximately 50 species. However, the phylogeny study of the Quercus genus in Vietnam has yet to be thoroughly explored. In this study, we utilize the genome-wide single-nucleotide polymorphisms (SNPs) data obtained through Multiplexed Inter Simple Sequence Repeat Genotyping by sequencing (MIG......

On some trematoda species of three genera Dictyonograptus Travassos, 1919; Platynosomoides yamaguti, 1971 and Skrjabinus (Bhalerao, 1936) (Dicrocoeliidae)
Academia Journal of Biology - - 2015
Dicrocoeliidae is a big trematoda family, including approximately 400 species belonging to 37 genera, but the taxonomy of this family is on discussion. Based on the characteristic of vitellaria, the genus Platynosomoides Yamaguti, 1971 is considered as a synonym of the genus Dictyonograptus Travassos, 1919. and the species Skrjabinus andersoni (Ko, 1976) should be placed into the genus Dictyonogra......
Study on the antagonistic mechanism of some selected fluorescent Pseudomonas strains toward Fusarium oxysporum
Academia Journal of Biology - Tập 28 Số 2 - Trang 77-81 - 2014
The presence of antifungal agents in 7 selected fluorescent Pseudomonas strains were tested. The obtained results showed that none of them was able to decompose chitin, laminarin and cellulose, but capable to use skim milk. All strains could produce siderophores and cyanid, but there was a difference among them. Only the P. fluorescens strain Ps7-1 showed the presence of phlD, one of 4 genes codin......
Some characteristics of growth process of longarm mullet (Mugil kelaartii Gunther, 1861) fish in O Loan lagoon, Phu Yen province
Academia Journal of Biology - Tập 32 Số 3 - Trang 7-11 - 2012
Longarm mullet (Mugil kelaartii) fish in lagoons O Loan, Phu Yen province is a kind of economic species and people can catch them with big production. This fish is a speciality of the locality due to its sweet-smelling and tastiness. At present, aquatic resource in lagoons and inshore zone of Phu Yen province is over-exploiting by destructive means that causes serious declining of Longarm mullet p......
Canthium simile Merr. & Chun (Rubiaceae), a new species for the flora of Vietnam
Academia Journal of Biology - - 2012
The genus Canthium Lamk. (Rubiaceae) in the world has about 200 species distributed in tropical, subtropical Asia and Africa. Vietnam has 9 species of this genus [Tran Ngoc Ninh 2005]. During the time to study specimen on this genus in Hanoi herbarium, we found one new species (Canthium Lamk.) for the flora of Vietnam. The species Canthium simile Merr. & Chun has been discoved from the Vu Xuan......
Effect of neurotoxins from the scorpion venom Lychas mucronatus Fabricius, 1708 on the exitatory nerve
Academia Journal of Biology - - 2015
These neurotoxins decrease the action potential (AP) value depending of the neurotoxin molecular weights (Mw). The AP rate is independent of the neurotoxin Mw indicating the direct influence of the toxins on Na+ and K+ channels located on the Ranhe oversize and no influence on the myelin nerve fibre state. No dependence is observed between the neurotoxin Mw and the threshold excitation of the nerv......
Influences of the light intensity and the NaCl concentration on the growth of two harmful marine microalgae species Prorocentrum rhathymum and Alexandrium tamarense
Academia Journal of Biology - Tập 28 Số 3 - Trang 43-48 - 2014
In Vietnam, among more than 70 harmful marine microalgae species which have been identified [6], Prorocentrum rhathymum and Alexandruim tamarense were two species of Dinophyta that had a very wide distribution on the coastal waters. This study investigated the influences of the light intensity and the NaCl concentration on the growth of these two isolated species in laboratory conditions. The expe......

Nghiên cứu về đặc điểm của gen chalcone synthase từ \(\textit{Pueraria lobata}\) và \(\textit{Pueraria mirifica}\) tại Việt Nam Dịch bởi AI
Academia Journal of Biology - Tập 43 Số 3 - Trang 47-58 - 2021
Hai loài thuộc chi Pueraria ((Pueraria lobata (tên đồng nghĩa: Pueraria montana var. lobata) và Pueraria mirifica (tên đồng nghĩa: Pueraria candollei var. mirifica)) là những cây thuốc cổ truyền đã được sử dụng trong y học từ thời cổ đại. Những cây này đã được sử dụng và trở thành cây thuốc bản địa có giá trị thương mại quan trọng. Hiện nay, cả rễ và hoa của P. mirifica được sử dụng như một thực p......
