Exosomes are small lipid vesicles, which are released from cells, and have been implicated as mediators of intracellular signaling, as well as a mechanism to remove material from the cell. We have shown that heat shock protein (HSP)60 is released from cardiac myocytes via exosomes. We investigated the stability of exo…
The results of study of 31 strains of green algae from ACKU collection represented by original isolates as well as by subcultures deposited in international collections of strains of the genus Stichococcus Nägeli are reported. In 19 strains previously undescribed mucous structures have been founded, viz colonial mucil…
The comparative analysis of ultrastructure of the photosynthetic cells and pigment content of Trapa natans in both floating and submerged leaves at vegetative phase were conducted. It has shown that the changes of cell ultrasructure and pigment content in leaves are depended from the location of leaves above or under…
Archaea have phytanyl ether lipids which is one of the characteristics that separates them from bacteria and eukaryotes. Some archaea have also unique membrane spanning tetrae- ther lipids (T EL); in Sulfolobus and Ihermoplasma species these TELmake up the majority of total membrane lipids. Archaeal lipids are able to…

In the materials there are presented, results of the synthesis and biological testing of the new nanocomposite which, contains silver nanoparticles incapsulated. in the synthetic polymer poly-1-vinyl-1,2,4-triazole. The synthesis method, of silvercontaining polymere nanocomposite is shown. With the use of modern equip…
The solubility in the quaternary water-salt systems LaCl 3 -NdCl 3 -HCl-H 2 O ( 1 ) and LaCl 3 -PrCl 3 -HCl-H 2 O ( 2 ) at 25°C was studied in the section of 40 wt % hydrochloric acid, a system with a eutonic discontinuity. The composition at the point of discontinuity for the eutonic solution is the following. In sys…
OBJECTIVE: To study the biocompatibility of porous calcium phosphate ceramics nanocomposite. METHODS: The biocompatibility was evaluated via experiments including the hemolysis test, hemopexis test, acute systemic toxicity test, pyrogen test, and intramuscular implant test, in which biphasic calcium phosphate nanocomp…
Gas chromatography (GC) is a powerful tool in the separation science of chiral analytes. The development of a new chiral test mixture for cyclodextrin (CD) coated GC columns allows comparing, choosing and identifying most suitable columns for a given separation challenge. This test mixture contains 12 enantiomer pairs…
Carbon nanomaterials formed during the combustion of Diesel inside engine is characterized by X-ray diffraction (XRD) and spectroscopic techniques. The soot are collected from the Engine and washed with Acetone. Carbon Nanomaterials produced from diesel soot show the morphology of carbon nanospheres mixed with carbon…
摘要： 以丙烯酸和腐植酸为原料，N,N-亚甲基双丙烯酰胺为交联剂，在水溶液中采用辉光放电电解等离子体引发聚合反应制备聚丙烯酸钠/腐植酸复合高吸水性树脂。 考察了放电电压、交联剂、丙烯酸中和度、后聚合温度、腐植酸钠和丙烯酸的含量对树脂吸水率的影响，讨论了树脂在0.9%氯化钠溶液中的溶胀速率和不同pH值溶液中的溶胀行为。 用红外光谱和热重分析分别对产物进行了结构表征和稳定性测试，结果表明，最佳的合成条件为：放电电压470 V、交联剂质量分数为0.6%、腐植酸钠质量分数为4%、丙烯酸质量分数为10%、中和度60%、后聚合温度70 ℃。 所得复合树脂对蒸馏水的吸水率为1152 g/g，对0.9%NaCl溶液的吸水率为89 g/g，800…

In-stent restenosis occurs in coronary arteries after implantation of drug-eluting stents with non-uniform restenosis thickness distribution in the artery cross section. Knowledge of the spatio-temporal drug uptake in the arterial wall is useful for investigating restenosis growth but may often be very expensive/diffi…
Red phosphorescent emitters were synthesized based on Ir(III) phenylquinoline complexes for applications to OLEDs. Ir(III) complexes 1-3 were based on 2-(biphenyl-3-yl)-quinoline units connected to various phenyl groups such as 5-phenyl, 5-(4-fluorophenyl), and 6-phenyl groups. The EL efficiencies were quite sensitive…
Using a hot-walled pulsed laser deposition (HW-PLD), nanowires (NWs) comprising 3 weight% Ga-doped ZnO (3GZO) have been successfully grown on a sapphire substrate. The structural and optical properties of 3GZO nanostructures have also been systematically investigated with respect to the target-substrate (T-S) distance…
Films of amorphous In(1-x)Sn(x)GaZnO(delta) (a-ISGZO) (x = 0.0-1.0) were pulsed laser deposited at a temperature range of room temperature to 300 degrees C, and in order to systematically investigate the effect of replacing In with Sn on the properties of amorphous In-Ga-Zn-O (a-IGZO), the electrical and optical prope…
The electron mobility and hole blocking ability of BPhen, BCP, and ET137 were investigated by fabricating an electron only device and hole only device, respectively. Although it was observed that ET137 has the highest electron mobility, the device with ET137 as electron transporting layer was unable to obtain high eff…
We investigated the imidization of a polyimide (PI) and the formation of Cu nanoparticles in a PI film by curinga precursor of PI (polyamic acid (PAA) dissolved in n-methyl-2-pyrrolidinone) in a reducing atmosphere in the rapid thermal annealing (RTA) system. A Cu film was deposited onto the SiO2/Si substrate, and the…
The effect of precursor ratio (H2O/DEZ) on the texture orientation, surface morphology, optical transparency and electrical resistivity of ZnO thin films deposited by MOCVD was investigated. Deposition temperature and pressure were fixed at 120 degrees C and 0.67 torr, respectively. The precursor ratio was varied betw…
