introduction the brachial plexus, a complex network of nerves, innervates to the upper limbs. variation in the course of the nerves in the upper limb is common. case presentation this paper describes two cases of upper limb variations in a cadaver dissected at lorestan university of medical sciences. in the first variation, the median nerve in the arm has a different route, so that the median m...

A characteriation of continuity of the $p$-$Lambda$-variation function is given and the Helly's selection principle for $Lambda BV^{(p)}$ functions is established. A characterization of the inclusion of Waterman-Shiba classes into classes of functions with given integral modulus of continuity is given. A useful estimate on modulus of variation of functions of class $Lambda BV^{(p)}$ is found.

The tail probabilities of two weighted sums of independent gamma random variables are compared when the first vector of weights majorizes the second vector of weights. The conjecture that the two cumulative distribution .functions cross exactly once is established in four special cases by means of the variation-diminishing property of totally positive kernels. Bounds are obtained for the locati...

background: temporal variation of stroke onset is suggested in some studies contained somewhat varieties. it is proposed that some predisposing changes occur in some ascertained times consequently resulted in stroke occurrence in some special times. objective: to determine the circadian and circaseptan variation of stroke onset. materials and methods: this cross sectional study was conducted fr...

statement of problem: variation in paranasal sinus anatomy as shown on computed tomographic scans is of potential significance for it may pose risks during surgery or predispose to certain pathologic conditions. purpose: the aim of this study was to assess the relative frequency and concurrence of variations in paranasal sinus anatomy in a given population and to compare the results with previo...

systemic lupus erythematosus (sle) is an autoimmune disease in which polymorphisms within the human leukocyte antigen (hla) region have been associated to its etiology. we conducted this study to compare the hla-dqb1 allelic sequence variation among sle patients and controls in the northeast of iran. genomic dna of 40 sle patients and 83 healthy controls were amplified by polymerase chain react...

results out of the 129 elderly participants, aged between 60-87 years (mean: 66.71 ± 6.21), males constituted 58.1% (n = 75) of patients and female were 41.9% (n = 54). normal variations of oral mucosa were observed in 62% (n = 80) of patients, while 44.2% (n = 57) had oral mucosal lesions. normal variations were significantly associated with smoking (or = 1.2), while denture wearers were at hi...

introduction: vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. they ascend the neck to enter the cranial cavity and supply blood to the brain. methods: a total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. this study was conducted in isfahan uni...

the nutrients are able to interact with molecular mechanisms and modulate the physiological functions in the body. the nutri­tional genomics focuses on the interaction between bioactive food components and the genome, which includes nutrigenet­ics and nutrigenomics. the influence of nutrients on f genes expression is called nutrigenomics, while the heterogene­ous response of gene variants to nu...
