Osteoradionecrosis, a rare complication of radiation therapy, is a slow progression disease which affects the surrounding structures of spinal components. It essentially weakens the soft tissue and bony configuration and can cause nerve impingement or cord compression. We describe a patient who underwent radiotherapy for thyroid cancer and presented with cervical kyphosis with anterolisthesis o...

in order to optimize use of water resources with selection of suitable wheat genotype(s) and irrigation schedule, in this experiment, the effect of elimination of irrigation at terminal growth and development stages of five wheat genotypes was investigated in two successive growing seasons (2002-03 and 2003-04) in the agricultural research station of torogh mashhad. split plot experiments were ...

Patients with porphyrias have varying degrees of photosensitivity, associated with elevated levels of porphyrins in plasma, erythrocyte, urine and/or feces. To investigate the role of complement in the pathogenesis of cutaneous lesions, varying amounts of uroporphyrin were added to normal human serum (0.1-10 microgram/ml), and the mixtures were then exposed to 405 nm irradiation. Such treatment...

The disulfide bridges of human complement component C3b, derived from C3 by removal of the 77-residue C3a, have been determined. The 10 bridges are Cys537-Cys794, Cys605-Cys640, Cys851-Cys1491, Cys1079-Cys1136, Cys1336-Cys1467, Cys1367-Cys1436, Cys1484-Cys1489, Cys1496-Cys1568, Cys1515-Cys1639, and Cys1615-Cys1624. Including the 3 bridges in C3a (Cys670-Cys698, Cys672-Cys705, and Cys685-Cys706)...

R(C4, K4) = 10 (see [2]) R(C4, K5) = 14 (see [3]) R(C5, K4) = 13, R(C5, K5) = 17 (see [5, 6]) R(Cn, K3) = 2n − 1 (n > 3) (see [4, 7]). In [10], we proved that R(Cn, K4) = 3(n − 1) + 1 (n ≥ 4). In this paper, we will prove that R(Cn, K5) = 4(n − 1)+ 1 (n = 6, 7). The following notations will be used in this paper. If G is a graph, the vertex set (resp. edge set) of G is denoted by V (G) (resp. E...

STUDY DESIGN Case-control study comparing sagittal plane segmental motion in women (n = 34) with chronic whiplash-associated disorders, Grades I-II, with women (n = 35) with chronic insidious onset neck pain and with a normal database of sagittal plane rotational and translational motion. OBJECTIVE To reveal whether women with chronic whiplash-associated disorders, Grades I-II, demonstrate ev...
