The topographical distribution of different fibre types was quantitatively determined within muscles of the lower hindlimb in rabbits and mice. The results were compared to those previously obtained, using the same new quantification methods, in homologous muscles of the rat. “Slow” type I fibres were identified and mapped out in crosssections stained for myofibrillar ATPase (in “slow” soleus d...

In 2007, research was carried out to determine the type and amount of asbestos fibers in a Croatian factory with a long history of making asbestos-containing products.Since the 1970s, asbestos fibres have been considered carcinogenic in humans i.e as a known cancer-causing agent. In the environment, asbestos fibres are inactive and naturally resist biodegradation. In time, fibres can only be gr...

During the past decades there has been considerable interest in the use of dietary fibre in both animal and human nutrition. In human subjects dietary fibre has been studied intensively for possible effects on body-weight management and health. In animal nutrition the interest in dietary fibre has increased because it can be used as a cheap source of energy and because of its potential to impro...

I. INTRODUCTION (a) Previous work According to the early work of von Frisch (1911) on the minnow, the nerve fibres responsible for active melanophore aggregation pass from the brain to the spinal cord and leave the latter at about the level of the 15th vertebra to enter the auto-nomic chain. There they run forwards and backwards, passing out with the spinal nerves and, in the head, with a branc...

In an editorial entitled 'Fiber carcinogenesis: is asbestos the only hazard?', Stanton (1974) drew attention to the possibility that inhaled fibres other than asbestos, and in particular glass fibres, could be carcinogenic to humans. The hypothesis was based on experiments carried out on rats. Specially-bred experimental animals were subjected to intrapleural application of large numbers of spe...

The myenteric plexus of the gastrointestinal tract was investigated in the obese diabetic mouse, an animal model of human type 2 diabetes. Sections were immunostained by the avidin-biotin complex method, using a general nerve marker, protein gene product 9.5 (PGP 9.5), as well as antibodies to several important neurotransmitters. Computerized image analysis was used for quantification. When dia...

Skinned fibres have advantages for comparing the muscle properties of different animal species because they can be prepared from a needle biopsy taken under field conditions. However, it is not clear how well the contractile properties of skinned fibres reflect the properties of the muscle fibres in vivo. Here, we compare the mechanical performance of intact fibre bundles and skinned fibres fro...
