The bull is the graph consisting of a triangle and two disjoint pendant edges. A graph is called bull-free if no induced subgraph of it is a bull. This is the first paper in a series of three. The goal of the series is to explicitly describe the structure of all bull-free graphs. In this paper we study the structure of bull-free graphs that contain as induced subgraphs three-edge-paths P and Q,...

the aim of this study was to determine the effects of the antioxidants superoxide dismutase (sod),glutathione peroxidase (gpx) and butylated hydroxytoluene (bht) on microscopic semen parameters andlipid peroxidation following the freeze-thawing of bull semen. ejaculates were collected from five holsteinbulls and pooled at 37°c. the semen samples were diluted with a cey extender containing addit...

Satellite cells support efficient postnatal skeletal muscle hypertrophy through fusion into the adjacent muscle fiber. Nuclear contribution allows for maintenance of the fiber myonuclear domain and proficient transcription of myogenic genes. Niche growth factors affect satellite cell biology; however, the interplay between fiber elasticity and microenvironment proteins remains largely unknown. ...
