background: cobalamin deficiency and peripheral neuropathy (pn) are commonly seen in hiv-infected adults. the level of urine methylmalonic acid (umma), a reliable indicator of tissue cobalamin status, was determined in hiv infected subjects with and without pn to establish this association. methods: one hundred and ninety-eight (198) consenting hiv infected subjects with and without pn were rec...

background: the purpose of this paper is to establish an easy and reliable biodosimeter protocol to evaluate the biological effects of proton beams. materials and methods: human peripheral blood lymphocytes were irradiated using proton beams (let: 34.6 kev μm−1), and the chromosome aberrations induced were analyzed using cytokinesis-blocked (cb) micronucleus (mn) assay. to determine the efficie...

abstract objective: diabetic peripheral neuropathy (dpn) is one of the most common complications of diabetes. beside the known factors such as hyperglycemia in the pathogenesis of this complication, other etiologies may play role in the pathogenesis of this complication. the aim of this study was the evaluation of the role of serum vitamin d and vitamin b12 levels in this process. material and ...

The eccentricity of a vertex $v$ is the maximum distance between $v$ and anyother vertex. A vertex with maximum eccentricity is called a peripheral vertex.The peripheral Wiener index $ PW(G)$ of a graph $G$ is defined as the sum ofthe distances between all pairs of peripheral vertices of $G.$ In this paper, weinitiate the study of the peripheral Wiener index and we investigate its basicproperti...

there is considerable agreement among linguists that thematic analysis offers writers insights into manuscripts that may be rejected by international journals due to thematic organization problems. whereas many comparative studies have provided valuable information about thematic progression (tp), the role of peripheral themes (pts) has almost been neglected. using the revised model of the tp p...

the effect of nerve growth factor (ngf) on regeneration of rat sciatic nerves in adult rat was studied. the sciatic nerve was cut out across a 6‑mm gap, then the proximal and distal stumps were inserted into the silicone tube chamber. 7s ngf was extracted from submaxillary gland and then was injected into the silicone in experimental group. after seven months nerve was transected and stained wi...
