Parent Rufus Bush Chats Cercotrichas galactotes perform of distraction display, approaching and flying away from potential predators near their nests while vocalizing and displaying their conspicuously coloured tail. The response of breeding pairs attending their first brood during the mid and final nestling stages was registered to stimuli of danger near their nests over two seasons. The first...

The temperate phage 59 from Erwinia carotovora and its DNA were studied. The phage particles have an icosahedral head and a long noncontractile tail with a base plate. The virus DNA makes up 50% of the total virus and exists as a linear molecule (molecular weight, 2.6 X 10(7)). A model of virus structural organization is presented.

A model for the growth of weighted networks is proposed. The model is based on the edge preferential selection. By the master equation approach, the distributions of strength, weight and degree are provided and results show that each distribution has a power-law tail. Particularly, the network has a high clustering coefficient.

INTRODUCTION Earlier work indicates that the cholesterol-lowering drug, simvastatin, is anabolic to chondrogenic expression of rat intervertebral disc (IVD) cells, which suggests a potential role for simvastatin in IVD regeneration. In this study, we expand on our earlier work to test the effectiveness of simvastatin on disc degeneration utilizing a rat tail disc degeneration model. METHODS 3...

The asymmetric forms (17 S and 13 S ) of acetylcholinesterase isolated from Torpedo californica electric organs have been subjected to collagenolytic and tryptic digestions and the hydrodynamic properties and component peptides of the products analyzed. The asymmetric forms contain the catalytic subunits and a trypsin-sensitive structural subunit attached to a filamentous collagen-like tail uni...

The growth and development of three groups of genetically identical F1 C57BL/6J female x SJL/J male mice were compared to examine whether embryo manipulation affects subsequent postnatal growth and development of mammalian embryos: (1) controls--the natural offspring of timed matings, (2) transferred controls--offspring from 2-cell embryos transferred to recipients 1 day asynchronous, and (3) t...

The product of gene 9 (gp9) of Salmonella typhimurium bacteriophage P22 is a multifunctional structural protein. This protein is both a specific glycosidase which imparts the adsorption characteristics of the phage for its host and a protein which participates in a specific assembly reaction during phage morphogenesis. We have begun a detailed biochemical and genetic analysis of this gene produ...

Leptin (LEP), the expression product of the obese gene produced primarily in the adipose tissue, is related to feed intake, growth and lipid metabolism. The aim of this study was to study the possible association between polymorphism of the LEP gene with growth and carcass traits among three Iranian sheep breeds of the Shal, Zandi and Zel varieties. A total of 180 purebred animals of the Shal, ...

Body weight and lengths of the wing, tail, tarsus, beak were measured in 139 black grouse (BG) Lyrurus tetrix (Linnaeus, 1758) 318 hazel (HG) Tetrastes bonasia captured north Arkhangelsk Region (Russia) 1990–2006. Almost all estimates are within average range parameters for Northern Europe (Norway – Komi Republic). Sexual dimorphism BG was revealed traits except wing length; by tail length appe...
