The expression of the intermediate filament (IF) constituents desmin, vimentin and keratin, as well as the striated-muscle-specific marker titin, was studied in mouse embryos of 8.0 to 9.5 days post coitum (d.p.c.), using the indirect immunofluorescence technique in combination with polyclonal and monoclonal antibodies. During the development of the embryo, desmin was first detected at 8.25 d.p...
ABSTRACf. The present study was concerned with the ultrastructure of the mandibular externus of the jaw and the tail skeletal muscles of U. aegyptia. Results obtained revealed differences in general morphology between the two muscles. The sarcoplasmic reticulum, T-system, and large deposits of glycogen granules, were encountered in the jaw muscle. However, the SR are not well developed. In cont...
The development of the myofibrillar apparatus in skeletal muscle is a process in which transmembrane linkages with adhesion molecules are implicated. Integrins are one class of transmembrane adhesion receptors which appear to mediate these interactions. Two prominent linkages are at the myotendinous junction (MTJ), which resides at the ends of the cell and connects myofibrils to the tendon, and...
The mechanisms of melt ejection and striation formation in laser cutting of mild steel are discussed. It is argued that the melt ejection from the cutting front is not a steady state process, but rather shows a cyclic phenomenon. The striation are strongly affected by the unstable characteristic of the thin liquid film on the cutting front during the melt ejection, together with the oxidation a...
