Freezing tolerance of sea urchin embryo pigment cells
Russian Journal of Marine Biology - Tập 42 - Trang 437-441 - 2016
N. V. Ageenko, K. V. Kiselev, N. A. Odintsova
Various stresses, including exposure to cold or heat, can result in a sharp increase in pigmentation of sea urchin embryos and larvae. The differentiation of pigment cells is accompanied by active expression of genes involved in the biosynthesis of naphthoquinone pigments and appears to be a part of the defense system protecting sea urchins against harmful factors. To clarify numerous issues occur...... hiện toàn bộ
The composition and structural characteristics of polysaccharides of the brown alga Eisenia bicyclis
Russian Journal of Marine Biology - Tập 39 - Trang 208-213 - 2013
R. V. Men’shova, S. P. Ermakova, B. H. Um, T. N. Zvyagintseva
The present study examines the polysaccharide composition of the brown alga Eisenia bicyclis. The major polysaccharide of E. bicyclis is shown to be sodium alginate (15.8% of the dry defatted alga weight). The yields of laminaran and fucoidan were 1.4% and 1.3% of the dry defatted alga weight, respectively. The alga contains laminaran (1,3;1,6-β-D-glucan) that has a unique structure, a high conten...... hiện toàn bộ
The effects of triterpene glycosides and phospholipids from marine invertebrates in the composition of tubular immunostimulating complexes on the immunogenicity of human serum albumin
Russian Journal of Marine Biology - Tập 41 - Trang 69-77 - 2015
N. S. Vorobyeva, A. N. Mazeika, L. A. Davydova, P. V. Velansky, A. V. Tsybulsky, E. Y. Kostetsky, N. M. Sanina
To study the adjuvant activity and to optimize tubular immunostimulating complexes (TI complexes) with respect to the soluble antigen, an investigation was performed on cucumariosides and their fractions, i.e., individual triterpene glycosides that were obtained from the holothurian Cucumaria japonica, as well as on phospholipids from the sea urchin Strongylocentrotus intermedius and the starfish ...... hiện toàn bộ
Communities of Coral Reefs of Central Vietnam
Russian Journal of Marine Biology - Tập 27 - Trang 197-200 - 2001
Yu. Ya. Latypov
Communities of macrobenthos on fringing reefs of central Vietnam were studied by the hydrobiological method using scuba diving. The species composition (more than 600 species), population densities of common species of the macrobenthos, and the degree of coverage of the substrate by corals and macrophytes were examined. Bottom communities classified on the basis of these data are indicative of the...... hiện toàn bộ

An annotated checklist of sea snakes of Vietnam, with notes on a new record of the yellow-lipped sea krait, Laticauda colubrina (Schneider, 1799) (Laticaudidae, Hydrophiidae)
Russian Journal of Marine Biology - Tập 32 - Trang 223-228 - 2006
V. E. Kharin
The yellow-lipped sea krait, Laticauda colubrina (Schneider, 1799), is recorded in the waters of Vietnam for the second time. The morphological characteristics of this species are described. Identification keys, a checklist, and distribution data for sea snakes of Vietnam are provided, proceeding from museum collections and extensive analysis of the available literature. Thalassophis anomalus P. S...... hiện toàn bộ
Ultrastructural Features of the Alimentary Canal in Hermaphroditic Appendicularians Oikopleura gracilis (Tunicata, Oikopleuridae)
Russian Journal of Marine Biology - Tập 49 - Trang S76-S89 - 2024
A. V. Savelieva
Appendicularians play an important role in marine food webs, but the alimentary canal of hermaphroditic oikopleurids, which prevalent among urochordates, is little studied ultrastructurally. Serial microtomy revealed that the alimentary canal of Oikopleura gracilis consists of a wide pharynx and a U-shaped gut with typical for oikopleurids anatomy: oesophagus, a bilobed stomach, the vertical, shor...... hiện toàn bộ
Concerning range expansion of the crabGeryon tridens in the Barents Sea
Russian Journal of Marine Biology - Tập 26 - Trang 200-203 - 2000
E. G. Berestovskii, V. N. Semenov, A. M. Sennikov
This paper presents data on 48 individuals of the rare high-boreal crab speciesGeryon tridens Krøyer, 1837, retrieved from the stomachs of cod caught in the southwestern part of the Barents Sea and adjacent waters in 1987–1997. There was only one large male with a carapace width of 58 mm; the other individuals were juveniles with carapace widths of 21–48 mm and masses of 3.2–27.5 g. The length: wi...... hiện toàn bộ

Influence of changes in sea water salinity on the growth, photosynthetic pigment content, and cell size of the benthic alga Attheya ussurensis Stonik, Orlova et Crawford, 2006 (Bacillariophyta)
Russian Journal of Marine Biology - Tập 37 - Trang 472-477 - 2012
N. A. Aizdaicher, Zh. V. Markina
The study deals with the effect of changes in salinity from 32 to 4‰ (at an interval of 4‰) on the growth, chlorophyll a and carotenoid contents, and cell size of the benthic alga Attheya ussurensis (Bacillariophyta). A. ussurensis showed high tolerance to reduced salinity and ability to adapt to salinity changes from 16 to 12‰. In this salinity range, the cells restored their shapes, sizes, and p...... hiện toàn bộ
