Smooth fiber

This study aims to investigate the effect of confining pressure on the shear resistance of UHPFRCs reinforced with different types of fiber: 1.5 vol.-% of the short smooth (SS, l/d = 13/0.2) fiber and the long smooth (LS, l/d = 30/0.3) were investigated.

The main objectives of this research work are as follows: (i) to explore the sensitivity of macro, meso and micro fibers to tensile and compressive properties of SFCs, and (ii) to correlate the tensile strength to compressive strength of SFCs containing macro, meso and micro steel-smooth fibers.

In this study, we have characterized the influence of hypoxia on the expression of hydroxylases crucially involved in col-lagen fiber formation, such as prolyl-4-hydroxylases (Ph4) and procollagen lysyl-hydroxylases (PLOD). Using the rat vascular smooth muscle cell line A7r5, we found that an hypoxic atmosphere caused a characteristic time-dependent five- to 12-fold up-regulation of the mRNAs of the two P4h a-subunits [aI (P4ha1) andaII (P4ha2)] and of two lysyl-hydroxylases (PLOD1 and PLOD2).

Vascular smooth muscle cell (VSMC) proliferation is an important etiologi-cal factor in vascular proliferative diseases such as primary atherosclerosis, hypertension, arterial and in-stent restenosis, and transplant vasculopathy. Our studies established that butyrate, a bacterial fermentation product of dietary fiber and a chromatin modulator, is a potent inhibitor of VSMC proliferation.

OF INVARIANT FIBER BUNDLES FOR DYNAMIC EQUATIONS ON MEASURE CHAINS ¨ CHRISTIAN POTZSCHE AND STEFAN SIEGMUND Received 8 August 2003 m -SMOOTHNESS We present a new self-contained and rigorous proof of the smoothness of invariant fiber bundles for dynamic equations on measure chains or time scales. Here, an invariant fiber bundle is the generalization of an invariant manifold to the nonautonomous case.

The theory of neurohumoral transmission received direct experimental validation nearly a century ago (see von Euler , 1981 ), and extensive investigation during the ensuing years led to its general acceptance. Nerves transmit information across most synapses and neuroeffector junctions by means of specific chemical agents known as neurohumoral transmitters or, more simply, neurotransmitters.

Classification Approximately 20 different groups of sarcomas are recognized on the basis of the pattern of differentiation toward normal tissue. For example, rhabdomyosarcoma shows evidence of skeletal muscle fibers with cross-striations; leiomyosarcomas contain interlacing fascicles of spindle cells resembling smooth muscle; and liposarcomas contain adipocytes. When precise characterization of the group is not possible, the tumors are called unclassified sarcomas. All of the primary bone sarcomas can also arise from soft tissues (e.g., extraskeletal osteosarcoma).

Neurogenic Disorders that affect the sacral spinal cord or the autonomic fibers to the penis preclude nervous system relaxation of penile smooth muscle, thus leading to ED. In patients with spinal cord injury, the degree of ED depends on the completeness and level of the lesion. Patients with incomplete lesions or injuries to the upper part of the spinal cord are more likely to retain erectile capabilities than those with complete lesions or injuries to the lower part.
