Talaromarins A-F: Six New Isocoumarins from Mangrove-Derived Fungus TGGP35.

Six new isocoumarin derivative talaromarins A-F (-), along with 17 known analogues (-), were isolated from the mangrove-derived fungus (Eurotiales: Trichocomaceae) TGGP35. Their structures were identified by detailed IR, UV, 1D/2D NMR and HR-ESI-MS spectra. The absolute configurations of new compounds were determined by the modified Mosher's method and a comparison of their CD spectra with dihydroisocoumarins described in the literature.

Activation of GIPR Exerts Analgesic and Anxiolytic-Like Effects in the Anterior Cingulate Cortex of Mice.

Background: Chronic pain is defined as pain that persists typically for a period of over six months. Chronic pain is often accompanied by an anxiety disorder, and these two tend to exacerbate each other. This can make the treatment of these conditions more difficult.

One new ,-unsaturated 7-ketone sterol from the mangrove-derived fungus sp.MGF222.

A new ,-unsaturated 7-ketone sterol, 5,6-epoxy-3, 15-dihydroxy-(22,24)-ergosta-8(14),22-dien-7-one (), along with five known sterone derivatives, 5,6-epoxy-3,7-dihydroxy-(22,24)-ergosta-8(14),22-dien-15-one (), 5,6-epoxy-3,7,9-trihydroxy-(22,24)-ergosta-8(14),22-dien-15-one (), 3,9,15-trihydroxy-(22,24)-10(5→4)-abeo-ergosta-6,8(14),22-trien-5-one (), 3,15-dihydroxyl-(22,24)-ergosta-5,8(14),22-trien-7-one () and (22,24)-ergosta-4,6,8(14),22-tetraen-3,15-dione () were isolated from the mangrove-derived fungus sp. MGF222. Their structures were established on the basis of extensive spectroscopic data and comparison with the data of literature.

Effects of CO(2) enrichment on growth and development of Impatiens hawkeri.

The effects of CO(2) enrichment on growth and development of Impatiens hawkeri, an important greenhouse flower, were investigated for the purpose of providing scientific basis for CO(2) enrichment to this species in greenhouse. The plants were grown in CO(2)-controlled growth chambers with 380 (the control) and 760 (CO(2) enrichment) μmol · mol(-1), respectively. The changes in morphology, physiology, biochemistry, and leaf ultrastructure of Impatiens were examined.

[Genetic diversity of the cultured populations of six rainbow trout Oncorhynchus mykiss by microsatllite].

Rainbow trout are cultured widely throughout the world for supplementation in natural ecosystems and for commercial aquaculture. In 1959 it was firstly introduced to China from Korea. After introduction from America and other countries such as Norway, Denmark, and so on, rainbow trout were now cultured in about 20 provinces in China.
