Dynamin and dynamin-related proteins (DRPs) mediate an array of membrane fission processes. A Tetrahymena DRP has adopted a new role, assisting in nuclear differentiation, a finding that further highlights these proteins - and this ciliate - as biological innovators.

Virginia were used. All these animals have similar micronuclei. During conjugation the pronuclei in the two conjugants are alike. Under such circumstances evidence of exchange of pronuclei was less convincing although there were many pairs in which an exchange evidently occurred. The migratory pronucleus was usually slender, the stationary pronucleus relatively short and broad. In many cases, t...

Background: Gallstone disease poses a substantial economic burden on healthcare systems globally, necessitating safer alternatives to current treatments like dissolution therapy and cholecystectomy. Natural compounds from plants offer potential solution, but research their cholelitholytic activity is limited. In vitro studies are crucial for identifying effective plant-based therapies. Objectiv...

Toona ciliata var. pubescens is considered an endangered tree species native to China. In order to help develop a conservation program for this species, we evaluated its genetic diversity and population genetics. We isolated microsatellite DNA loci using streptavidin beads. A genomic library, enriched with microsatellites, was constructed and screened by sequencing. We detected 8 polymorphic mi...

Veronica ciliata Fisch. has traditionally been used in Tibetan medicine for the treatment of hepatitis, cholecystitis, rheumatism, and urticaria. We analyzed the chemical composition of the iridoid glycosides fraction (IGF) isolated from V. ciliata and evaluated the antioxidant and hepatoprotective properties. The IGF was separated by high-speed countercurrent chromatography (HSCCC) and the mai...

This study evaluated the effect of salinity and soilless media on vegetative growth, phytochemicals, antioxidant capacity Trachyandra ciliata (wild cabbage) to develop its growth protocol explore potential as a natural source secondary metabolites. Treatments consisted different concentrations sodium chloride (NaCl), control- 0 mM, 100 200 400 while in vitro assays were used for phytochemical s...

Ung thư gan là loại ung đứng đầu về tỷ lệ gây chết. Các nghiên cứu tiềm năng chống từ nhiều loài thảo dược khác nhau đang được quan tâm hiện nay. Elsholtzia ciliata (Thunb.) Hyland thuộc chi sử dụng phổ biến như một gia vị và thuốc chữa cảm cúm. Tuy nhiên, khả ức chế tế bào của nó còn chưa cứu. Trong này, các phương pháp nuôi cấy, phân tích độc tính bào, chu kỳ apoptosis áp để đánh giá kháng ca...

Community biomass is often less variable than the biomasses of populations within the community, yet attempts to implicate compensatory dynamics between populations as a cause of this relationship often fail. In part, this may be due to the lack of appropriate metrics for variability, but there is also great potential for large-scale processes such as seasonality or longer-term environmental ch...

Three new norlimonoids, toonaciliatins A (1), F (6), and G (7), four new limonoids, toonaciliatins B-E (2-5), and five known compounds, 5alpha,6beta,8alpha-trihydroxy-28-norisotoonafolin (8), toonaciliatins H (9) and I (10), febrifugin (11), and khayasin T (12), were isolated from the leaves and stems of Toona ciliata. Compounds 1-3 have an unusual 1-en-3-one system with a 1,11-oxygen bridge, l...
