Maximum uptake of liposome-encapsulated fluorescein diacetate by Daucus carota protoplasts was observed when 6 x 10(6) protoplasts per milliliter were incubated with 2.4 x 10(7) liposomes per milliliter for 1 hour. In the case of Nicotiana glutinosa protoplasts, optimum ratio of protoplasts to liposomes was 1:10, where 2.3 x 10(5) protoplasts per milliliter were provided. Neutral and positive l...
BACKGROUND Chimeric molecules comprising the A-chain of tissue-type plasminogen activator (t-PA) and the catalytic domain of urokinase-type plasminogen activator (u-PA) have intact enzymatic characteristics of u-PA, partial fibrin-binding properties of t-PA, and thrombolytic properties in animal models comparable with but not superior to those of single-chain u-PA (scu-PA). Deletion of the fing...
ABSTRACT: Retinoic acid "one of the derivatives of vitamin A "has different morphogenic and teratogenic effects on developing organs. For this reason, the present study is an attempt to examine the effects of retinoic acid on limb bud ,eye and body axis of chick embryo in the stages of 11-12 Humburger and Hamilton. The experiments cartied out in this study was based on 140 white eggs which h...
background and aims. current chemical methods may not efficiently disinfect dental stone casts. the aim of this study was to investigate if microwave irradiation is effective for disinfection of stone casts. materials and methods. in this laboratory study, three groups (n = 162) of prepared spherical stone beads as carriers with a diameter of 10 mm were inoculated by separately soaking in three...
abstract the cr(iii) and zn(ii) complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl)benzoic acid as ligand have been prepared by reacting cr(no3) and zn(no3)2 and ligand in cloroform. the cr and zn complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl) were also prepared in chloroform and aceton solutions. the uv-visible and ft-ir spectra of...
Myocardial injury was induced in 25 dogs by infusing isoprenaline, 2-4 microgram per kg per minute for the duration of six hours. 10 dogs served as controls which received only physiological saline. Animals receiving isoprenaline 2 microgram per kg per minute were labelled as experimental group A and other receiving microgram per kg per minute as experimental group B. Histopathological obs...

Background and purpose: Ït has been found that the use of different drugs for laryngoscopy preparation and tracheal intubation results in controversy. The aim of this study is to compare the haemodynamic effects of remifentanil with fentanyl for tracheal intubation in patients undergoing coronary artery bypass grafting (ÇÂBG). Materials and methods: This is a randomized and double-blind st...
introduction: the most important virulence factor of brucella is related to its capability of intraphagocytic survival. brucella with this ability,causes persistant infection in host. garlic extract, because of has organosulfur compounds such as allicin, has antimicrobial activity. the aim of this study was to investigate the effect of garlic choloroformic extract on intramacrophage brucella sp...
