It is well known that the microenvironment plays a major role in breast cancer progression. Yet, the mechanism explaining the transition from normal fibroblasts to cancer-stimulated fibroblasts remains to be elucidated. Here we report a FTIR imaging study of the effects of three different breast cancer cell lines on normal fibroblasts in culture. Fibroblast activation process was monitored by F...
abstract: one of the most visited & important spaces in different countries by tourist are urban areas. the old tehran which major part is located in district 12 is historical showcase of the capital, but, its hiidden cultural attraction is not used as it should be. this thesis occasionally engage in studying the efficacy of correct installation of travel guide boards in welfare & easily acc...
The strong association of iodine with organic material and the presence of the cosmogenic radioisotope I make the iodine isotopic system useful in tracing and dating studies of organic materials and their derivatives. We present here results from two new applications of this system, investigations of gas hydrates from the Peru Margin (ODP 201, Site 1230) and of fluids collected from the fore ar...

We present sensitive radio continuum imaging at 1.4 GHz and 4.9 GHz of seven high redshift QSOs selected for having a 240 GHz continuum detection, which is thought to be thermal dust emission. We detect radio continuum emission from four of the sources: BRI 0952−0115, BR 1202−0725, LBQS 1230+1627B, and BRI 1335−0417. The radio source in BR 1202−0725 is resolved into two components, coincident w...
While gold nanorods have been extensively studied and used in many biological, plasmonics, and sensing applications, their conventional seed-mediated synthesis still presents a number of limitations. Its high sensitivity to the concentration of the reducing agent (ascorbic acid) leads to problems with reliability as well as extremely poor yield of ionic-to-metallic gold conversion, which is onl...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
A Itália do século XIII era uma região bastante dinâmica em termos políticos e religiosos, um espaço de disputas entre diferentes instituições, grupos personagens. Nas décadas 1220 1230 houve recrudescimento dos confrontos o imperador Frederico II as comunas italianas, bem como das políticas cidades no interior delas. Este cenário conflituoso representou oportunidade para a atuação papado seus ...
background: hair dye poisoning, with main toxic component paraphenylene diamine, is a medical emergency. it is on increasing trend in developing countries due to wide availability and low cost of hair dyes. it carries a high mortality and does not have any specific antidote. case report: twenty three years old patient presented with breathelessness along with difficulty in speaking for one hou...
