Analysis of an RNA-Seq library from cucumber leaf RNA revealed the first complete genome sequence of Cucurbit aphid-borne yellows virus (CABYV) from Papua New Guinea. We compared it with 36 complete CABYV genomes from other world regions. It most resembled the genome of South Korean isolate GS6.

The near infrared (NIR) absorption and average particle size of gold nanostars (GNSs) can be precisely controlled by varying the molar ratios of cucurbit[7]urils (CB[7]) and GNSs in aqueous solution. GNSs modified with CB[7] achieved high cargo loading with thermally activated release upon the NIR laser irradiation.

A stable 1:1:1 inclusion complex of Ru(bpy)(3)-phenol (1), MV(2+) and cucurbit[8]uril (CB[8]) is formed in aqueous solution. In the presence of triethanolamine (TEOA), a light-induced formation of unusual partner radical trimer 1-(MV(+*))(2)-CB[8] has been observed for the first time.

While a single pillar[6]arene ring, nestling between two cucurbit[6]uril rings in a series of three hetero[4]rotaxanes, is conformationally mobile in solution, it adopts the energetically most favourable conformation with local C3V symmetry in the solid state.

Cucurbit[5]uril hydrochloride hydrate crystals with large water-filled channels transform to a highly stable layer structure via a single-crystal to single-crystal mechanism; (129)Xe NMR showed that porosity in CB[5] samples depends critically on the method of preparation.

The reversibly switchable trans-chalcone/flavylium photochromic system was successfully coupled to the complexation equilibrium of a drug-cucurbit[7]uril host-guest assembly. Hence, the phototriggered release of memantine under illumination at 366 nm was observed. The process can be partially reverted through a thermally activated back reaction.

obesity is rising rapidly in iran. nutrition is an important issue of obesity; fruits and vegetables are among the best food sources of antioxidant vitamins, soluble fibers, phytochemicals, and other nutrient constituents. further, some of these foods have been shown to be protective related to reduction of chronic disease risk. in this study, consumption of fruits & vegetables and body mass in...

OBJECTIVE To examine associations between parenting styles, family structure and aspects of adolescent dietary behaviour. DESIGN Cross-sectional study. SETTING Secondary schools in the East Midlands, UK. SUBJECTS Adolescents aged 12-16 years (n 328, 57 % boys) completed an FFQ assessing their consumption of fruit, vegetables, unhealthy snacks and breakfast. Adolescents provided informatio...
