The rabbit reticulocyte is capable of utilizing purines and their ribosyl derivatives for nucleoside triphosphate formation. Adenine, adenosine, hypoxanthine, and inosine are used extensively for the synthesis of adenosine triphosphate. Xanthine, guanine, and guanosine are utilized primarily for the synthesis of guanosine triphosphate. The inhibitor 6-diazo-S-oxo-L-norleucine inhibits the utili...

1. Incubation of rabbit cardiac-muscle troponin I with phosphorylase b kinase leads to the incorporation of .07-1.2 mol of Pi/mol. 2. The major site of phosphorylation is a serine residue at position 72. 3. Lesser amounts of phosphate are incorporated into threonine-138, threonine-162 and serine 20. 4. Serine-20 is the only site that contains a significant amount of phosphate before incubation ...

Rabbits may develop a self-injurious behavior and hurt themselves severely. Lactating females can, in turn, hurt their newborn kits by chewing or excessively licking their ears and their limbs. Self-injurious behavior of body regions is observed in rabbits suffering from specific pathologies, in does (adult female rabbits) with a very strong maternal instinct (Figure 1) as well as in individual...

Polyclonal antibodies were generated in rabbits by delivery to skin of gold particles coated with mammalian expression vectors encoding a cytoplasmic (beta-galactosidase) or a nuclear (L1 capsid of cottontail rabbit papillomavirus) protein. One primary and one booster immunization of 30 micrograms DNA per rabbit yielded specific antisera with titers from 1:24 000 to 1:120 000 in each of eight r...

Cultivation of Bacterium pneumosintes in the collodion sac dialysate of a tissue medium produces an antigen suitable for serological tests. Injection of dialysate cultures of Bacterium pneumosintes into rabbits results in the production of antibodies demonstrable by agglutination, precipitation, complement fixation, and phagocytic reactions. Four strains of Bacterium pneumosintes, three from th...

UNLABELLED The ideal approach for the treatment of glottal insufficiency remains a challenge for laryngologists. AIM This experimental study assessed the histological changes and fibrosis caused by autologous fascia lata grafts into the rabbit voice muscle. STUDY DESIGN A clinical and experimental study. METHODS A 0.2 × 0.2 cm fragment of autologous fascia lata was grafted into the right ...

<p>Rabbit production has great growth potential in a country where animal is very important. However, there little data about this industry Southern and Southeast Brazil. The aim of study was to describe Brazilian rabbit farms that provide meat, pets animals for learning or research. Three pet farms, four meat five research were visited, the farm characteristics collected between June 201...

After microinjection of hemoglobin mRNA from rabbit reticulocytes (9S mRNA) into Xenopus laevis oocytes, the cytological structure remains normal. The peroxidase reaction does not show an accumulation of synthesized hemoglobin in the germinal vesicle. Fertilized Pleurodeles Waltlii eggs synthesize rabbit hemoglobin after injection of 9S mRNA; hemoglobin synthesis decreases as development progre...

King in 1940, in this journal, described appearances that he believed to be those of myocardial regeneration in a case where death had occurred four days after a stab wound of the chest. A review of the literature, however, shows the opinion most generally held is that hyperplasia of cardiac muscle does not occur. Another consideration prompted the present study: Le Gros Clark (1946) showed tha...
