conclusions patients with hiv/aids are more likely to acquire other stis, because the same behaviors that increase the risk of becoming hiv infected can also increase the risk of acquiring stis. having a sore on the skin due to an sti can make the transmission of hiv to the sex partner more likely than people who don’t have such sore in their genital area. results among the 41 patients with hiv...

lu3+/yb3+ and lu3+/er3+ co-doped sb2se3 nanomaterials were synthesized by a co-reduction method in hydrothermal condition. powder xrd patterns indicate that the lnxln′xsb2-2xse3 ln: lu3+/yb3+ and lu3+/er3+ crystals (x= 0.00-0.04) are isostructural with sb2se3. the cell parameters were increased for compounds upon increasing the dopant content (x). sem and tem images show that co-doping of lu3+/...

conclusions the results of the current study showed a high rate of co-infection of m. tuberculosis and p. jirovecii in the iranian patients with hiv. as the immune system condition worsened, the probability of occurrence of pneumocystis pneumonia (pcp) increased. therefore, more specific, most rapid and sensitive tests should be utilized for diagnosis of pcp in this group of patients. results a...

hepatitis b virus (hbv) is the most prevalent viral infection and is among the leading causes of human liver diseases. nearly 360 millions of people are world widely infected with prolonged forms of hepatitis b including active and inactive chronic forms. chronic hepatitis b (chb) is associated with cirrhosis and hepatocellular carcinoma (hcc) in patients suffering from congenital and/or acquir...

a facile and simple method was proposed to control the size and shape of the mgo nano structures with high surface area in the presence of efficient and cheap templates like peg 200, peg 600, peg 4000 and sorbitol at low temperature within a little time. nano rods and nanoparticles have been achieved by applying these templates and altering other growth parameters. the products were characteriz...

in the past decade, magnetic nanomaterials have attracted much attention due to their physical properties and technological applications. in this work, α-fe2o3 nanoparticles were first synthesized via a simple co-precipitation method using iron chloride hexahydrate (fecl3.6h2o) as precursor and ammonia solution as precipitator. the samples were then characterized by high resolution transmission...

cobalt chromite (cocr2o4) with normal spinel structure, shows catalytic activity for oxidation of unburned methane in the natural gas vehilcles (ngv). in this study, cocr2o4 nanoparticles were synthesized through a conventional co-precipitation technique and investigated for the catalytic combustion of methane. cobalt nitrate hexahydrate, chromium nitrate nonahydrate and ammonia solution (25%) ...
