C14 Assays and Autoradiographic Studies on the Rooster Comb
The distribution of C(14) was studied in various parts of the rooster comb following treatment with testosterone. The value of gas-phase assay of C(14) in tissue has been demonstrated and the results compared with those of autoradiographic studies on the same tissue. The results of these experiments showed that androgen treatment significantly increases the rate of incorporation of C(14) in var...
متن کاملRooster comb hyaluronate-protein, a non-covalently linked complex.
Hyaluronate from rooster comb was isolated by ion-exchange chromatography on DEAE-cellulose from tissue extracts and papain digests. The preparations were labelled with [14C]acetic anhydride and subjected to CsCl-density-gradient centrifugation in 4 M-guanidinium chloride in the presence and absence of 4% ZwittergentTM 3-12. A radioactive protein fraction was separated from the hyaluronate when...
متن کاملRooster Collagen Extracts from Rooster By-Products
Collagen associated hydrolysates have desirable characteristics for various industrial applications [1,2]. They have been used as important biomaterial in medical applications because of their biodegradability and weak antigenicity [3]. In addition, intracellular and extra-cellular self-assembly of polypeptide chains and the cross-links between adjacent molecules help collagen fibrils to withst...
متن کاملResearch Note Sheep Ingestion of Water Containing Quebracho or Black Wattle Tannin
Ingestion of small amounts of condensed tannin (CT) by ruminants can produce valuable outcomes such as improved nitrogen use and reduced bloating, methane output, and gastrointestinal parasitism. However, many grasses and forbs contain little if any CT. The specific types of CT vary in plants and can have somewhat different effects on ruminants. Individual ruminants can respond differently to C...
متن کاملThe Rooster and the Butterflies
This paper describes a machine-checked proof of the JordanHölder theorem for finite groups. This purpose of this description is to discuss the representation of the elementary concepts of finite group theory inside type theory. The design choices underlying these representations were crucial to the successful formalization of a complete proof of the Odd Order Theorem with the Coq system.
