conclusion fm is more sensitive than zn for diagnosis of tb. however, since fm is more sensitive and rapid, using this method in clinical laboratories with large specimen numbers is recommended. results a total of 102 out of 920 study subjects had pulmonary tb, of them 68 (66.66%) patients were smear positive by either staining method while others were smear negative. the proportion of positive...

background: giardia lamblia is one of the most common protozoal infections in human especially children. metronidazol (mtz) is the drug of choice for treatment of giardiasis; its chemical composition possesses major threats and is becoming less sensitive. this study aimed to search for natural extracts alternative to mtz. methods: in-vivo effects of dichloromethane extracts of ginger and cinnam...

background: the aim of this study was to determine the correlation between ultrastructural studies for pinopodes expression after ovarian hyperstimulation and progesterone injection in mice. materials and methods: adult nmri mice were superovulated using human menopasual gonadotropic (hmg) and human chorionic gonadotropic (hcg) hormones; after that, daily injection of progesterone (1 mg/mouse) ...

highly self-ordered alumina nanopore arrays were fabricated using hard anodization technique in different mixtures of oxalic/phosphoric acid. the phosphoric acid concentration was varied from 0.05 to 0.3 m while the oxalic acid concentration was changed between 0.3 and 0.4 m. the self ordered nanoporous arrays were obtained in anodization voltage changing from 130 to 200 v. the interpore distan...

background copper (cu) is an essential trace element involved in normal reproduction but its overexposure may produce some detrimental effects. the aim of this study was to investigate the effects of copper sulfate poisoning on morphometery of mice ovarian structures and probable intracellular changes. methods thirty mature female mice were randomly allocated to control and two treatment groups...

confocal laser scanning microscopy (clsm) is a revolutionary advance in the field of light microscopy which, in recent years, has been used on interaction studies between host and pathogen. this study carried out on the flag leaves of the susceptible spring wheat cultivar (triticum aestivum l.) known as thatcher and its near isogenic line with the yr-18 adult-plant resistance gene to stripe rus...

– the normal and lateral line cycloid scales of a cyprinid fish capoeta damascina (valenciennes incuvier and valenciennes, 1842) have been subjected to the scanning electron microscopy technique in orderto study their detailed structure. the scales have the general morphological characteristics of the cycloidscales. in the normal scale located below the dorsal fin, the focus lies towards the an...

conclusions alterations were present in both the aspect and spacing of collagen fibrils and in the shape of elastic fibers. the present familial combination of scad and edsh, with almost similar ultrastructural features suggests a possible connection between both conditions. case presentation we present a woman with scad and her five close relatives showing obvious or suggestive signs of edsh. ...

introduction: today, have been approved scientifically relationship between presence of asbestos fibers in the human respiratory area and malignant diseases such as lung advanced fibrosis (asbestosis), gastrointestinal, lung and laryngeal cancers. the aim of this study was the determination of asbestos fibers concentration in yazd city’s air in the summer of 2015. methods: this is a descriptive...
