Five illitic clays were treated with various inorganic cations and heated to over 1400~ in a high-temperature X-ray diffraction furnace. The illite lattice undergoes dehydroxylation from 475-600~ and the resulting anhydrides begin to disappear at 850~ The major high-temperature phases formed from untreated illites are/?-quartz (1000-1300~ spinel (1000-1400~ and mullite (1150-1400 + ~ Minor amou...

background: cholangiocarcinoma is an invasive biliary malignancy with poor prognosis. diagnostic accuracy of conventional methods is low which is mainly due to the specific anatomy of the disease. the aim of this study was to evaluate the diagnostic value of biochemical profile and tumor marker of the bile in patients with malignant cholestasis compared to that of choledocholithiasis. methods: ...

introduction: about one third of the world's population is infected with tuberculosis (tb) and each year, about 1.5 to 2 million people die from tb. procalcitonin (pct) is an inflammatory marker that its level has variable materials and methods: this conducted on patients with pulmonary tb. data were collected using a check list. the serum level of pct was measured by elisa test at the beg...

genetic markers are one of the advances which have occured in the genomics era. among genetic markers, molecular markers mainly because of their abundance, are the most widely used them. development of molecular markers has greatly altered genetics and plant breeding. genetic markers indicate the genetic differences between different organs or species. some studies which were conducted during t...

abstract background: autosomal dominant polycystic kidney disease (adpkd) is an inherited disorder with genetic heterogeneity. up to three loci are involved in this disease, pkdi on chromosome 16p13.3, pkd2 on 4q21, and a third locus of unknown location. methods: here we report the first molecular genetic study of adpkd and the existence oflocus heterogeneity for adpkd in the iranian population...

samples from five sturgeon species including persian sturgeon (acipenser persicus), russian sturgeon (a. gueldenstaedti), great sturgeon (huso huso),ship sturgeon (a. nudi-ventris) and stellate sturgeon (a. stellatus) were collected from the south caspian sea. dna was extracted from the fins, eggs and skeleton muscle of the five species. rapd markers were used for identifying different kinds of...

in this study, the genetic diversity among paecilomyces variotti isolaes was investigated. sampling was performed from pistachio garden in seven geographical region of kerman province during 2011-2012. seventy isolates were identified as p. variotii species using morphological criteria. the genetic diversity among 20 selected isolates was assayed by variation at ssr marker bands using 12 pair p...

background and objective: serum creatinine is the most used endogenous marker of glomerular filtration rate (gfr), but it also has multiple limitations. therefore, some surrogate gfr markers, such as beta trace protein, have been introduced for gfr estimation. the aim of our study was to estimate gfr by serum beta trace protein using three available equations and compare them to dtpa gfr as the...

objective: the current methods for bladder cancer diagnosis suffer from low sensitivity and specificity. therefore, finding a novel tumor markers with high specificity and sensitivity is of great interest. micrornas (mirna, mir) are small endogenously-produced, non-coding rnas with an important role in regulating gene expression. recent studies show that mirnas expression profiles represent sig...

to determine the role of ddx3y gene in spermatogenesis and infertility in bulls, blood samples were collected from five infertile bulls (azoospermic; no sperm in the semen) at the animal breeding center in karaj, iran. the recommended human primers by eaa/eqmn were investigated using the blastn database for sts marker detection. alignment of sts marker genes with bovine genome was performed. pr...
