Abstract Comparative studies of different isolates Neonectria ditissima obtained from canker lesions and rotten fruit showed that both five-septate macroconidia aseptate microconidia were capable germination by germ-tube formation, but growth commenced earlier proceeded faster the former than latter type spore. Further, following wound inoculation apple with numbers conidia (50, 500 or 5000 per...

To identify a set of genes involved in the development of radiation-induced tumorigenesis, we used DNA microarrays consisting of 1176 mouse genes and compared expression profiles of radioresistant cells, designated NIH3T3-R1 and NIH3T3-R4. These cells were tumorigenic in a nude mouse grafting system, as compared with the parental NIH3T3 cells. Expression of MDM2, CDK6 and CDC25B was found to in...

1. Human growth hormone was prepared from acetone-dried residues after extraction of gonadotrophins from pituitary glands. 2. Crude growth hormone was purified by gel filtration on Sephadex, resulting in a product that is soluble in water or 0.5% sodium chloride. It is painless on injection and shows a twofold increase in biological potency. Aggregation of growth hormone on Sephadex columns can...

We show that small solids in low mass, turbulent protoplanetary disks collect into self-gravitating rings. Growth is faster than disk lifetimes and radial drift times for moderately strong turbulence, characterized by dimensionless diffusivities, αg . 10 —10 when particles are mm-sized. This range reflects a strong dependance on disk models. Growth is faster for higher particle surface densitie...

BACKGROUND Early menarche tends to be preceded by rapid infancy weight gain and is associated with increased childhood and adult obesity risk. As age at menarche is a heritable trait, we hypothesised that age at menarche in the mother may in turn predict her children's early growth and obesity risk. METHODS AND FINDINGS We tested associations between mother's age at menarche, mother's adult b...
