Nitric oxide (NO) produced from endothelial cells plays a critical role in vascular physiology. The regulation of endothelial NO synthase (eNOS) involves various mechanisms including multiple Ser/Thr phosphorylations. Recently, eNOS-Ser617 was newly recognized to be phosphorylated in response to humoral factors including vascular endothelial growth factor. However, it remains unknown whether and how eNOS-Ser617 phosphorylation is stimulated by shear stress, the primary stimulus of endothelial NO production. This issue was explored in the present study using cultured bovine aortic endothelial cells (BAECs). Over-expression of a constitutively active protein kinase B(Akt) mutant in BAECs increased Ser617 phosphorylation while constitutively active protein kinase A mutant had no effect. When BAECs were subjected to an arterial level of laminar shear stress, eNOS-Ser617 phosphorylation was clearly increased in a time-dependent manner. Shear stress also stimulated Akt phosphorylation at Thr308, one of the key regulatory sites. The time courses of eNOS-Ser617 and Akt-Thr308 phosphorylations appeared to be very similar. These results suggested that eNOS-Ser617 phosphorylation, mediated by Akt, is a physiological response to the mechanical shear stress, involved in the regulation of NO production in endothelial cells.

Celastrus orbiculatus (CO) has been used as a traditional herb medicine to treat fever, chill, joint pain, edema, rheumatoid arthritis and bacterial infection in China and Korea. In this study, we investigated anticarcinogenic effects of Celastrus orbiculatus (CO). CO was extracted with methanol (COM), and then further fractionated into four different types: methanol (COMM), hexane (COMH), butanol (COMB) and aqueous (COMA) partition layers. We determined the cytotoxicity of these four partitions in four kind of cancer cell lines, such as HepG2, MCF-7, HT29 and B16F10 Cells by MTT assay. Among various partition layers of CO, the COMM showed the strongest cytotoxic effects on cancer cell lines we used. We also observed quinone reductase (QR) induced effects in all partition layers of CO on HepG2 cells. The QR induced effects of COMM on HepG2 cells at 80 ${\mu}$ g/mL concentration indicated 3.28 to a control value of 1.0. The COMM showed the highest induction activity of quinone reductase on HepG2 cells among the other partition layers. Although further studies are needed, the present work suggests that CO may be a chemopreventive agent for the treatment of human cells.

The study aims to identify the role of transformational leadership toward work performance through intrinsic motivation in pharmaceutical field by a survey of 220 pharmacists in Vietnam. The pharmaceutical industry in Vietnam is experiencing rapid growth, accompanied by the need for a change in leadership for managers. The transformational leadership creates a proactive, positive attitude, passion, interest or an increase in intrinsic motivation of employees, thereby affecting work performance. This study performed reliable verification by Cronbach's Alpha coefficient, then the factors are analyzed by EFA before conducting multivariate regression analysis. The results showed that the transformational leadership style includes such factors as: idealized influence (attributed and behavior), inspirational motivation, intellectual stimulation, individualized consideration have a positive impact on intrinsic motivation and thereby positively affecting work performance. It confirms that employees will have a higher intrinsic motivation level when working under transformational leadership from their leaders. It makes employees work more efficiently. According to the research results, the pharmacist has an intrinsic motivation to work hard on tasks that contribute to the group overall goal of. That requires managers to have a task assignment strategy to connect the goals of the members together as well as of the members to the group.

The global movie industry is continuing rapid growth through application of the latest technology. 3D movies are being produced and shown for a more effective viewing experience. Special chairs for audiences are being experimentally manufactured and installed for the greatest viewing effect. This special chair has a structure that applies vibrating stimuli to specific parts of the body by attaching vibration transducers to theater chairs and synchronizing it with each scene of the movie. In a previous study, it has been confirmed that we can analyze the vibration transfer characteristics of sponge seats through the application of an experimental modal analysis method and obtain design variables easily. In this paper, we examine the major design parameters needed in the development of a foaming sponge seat in which auxiliary springs are inserted to improve the vibration transfer effect of a chair seat. Through analyzing several prototypes by applying experimentation as well as the experimental modal analysis method, it was confirmed that the effect of vibration transfer can be improved through the use of an auxiliary member.

Thirty lactating Javanese thin-tail ewes (12 ewes had been injected, prior to mating, with 700 IU pregnant mare serum gonadotropin, and 18 ewes with saline as a control) were used to evaluate the effect of superovulation on milk production during lactation and mammary chemical indices at the end of lactation. Thirteen ewes (9 control and 4 superovulated ewes) were fed at low and the other 17 ewes (9 control and 8 superovulated ewes) were fed at high quality ration. Superovulated ewes, either fed at low or high quality ration, had dramatically higher milk yields (57%). At the end of lactation, superovulated ewes had higher mammary dry fat-free tissue, mammary DNA concentration, total mammary DNA and RNA contents than nonsuperovulated ewes. Superovulation did not affect mammary RNA and collagen concentrations, and total collagen content. Ration quality did not significantly increase milk production during lactation and mammary chemical indices at the end of lactation. The observed increase in milk production in the superovulated ewes was probably due to the increased mammary secretory cell number and their synthetic activities during lactation as a result of the increased endogenous hormonal stimulation of mammary growth and development during pregnancy.

Direct-fed microbials (DFM) have been used to enhance milk production in lactating cattle and to increase feed efficiency and body weight gain in growing ruminants. Primary microorganisms that have been used as DFM for ruminants are fungal cultures including Aspergillus oryzae and Saccharomyces cerevisiae and lactic acid bacteria such as Lactobacillus or Streptococcus. Attempts have been made to determine the basic mechanisms describing beneficial effects of DFM supplements. Various modes of action for DFM have been suggested including : stimulation of ruminal microbial growth, stabilization of ruminal pH, changes in ruminal microbial fermentation pattern, increases in digestibility of nutrients ingested, greater nutrient flow to the small intestine, greater nutrient retention and alleviation of stress, however, these responses have not been observed consistently. Variations in microbial supplements, dosage level, production level and age of the animal, diet and environmental condition or various combinations of the above may partially explain the inconsistencies in response. This review summarizes production responses that have been observed under various conditions with supplemental DFM and also corresponding modification of ruminal fermentation and other changes in the gastrointestinal tract of ruminant animals.

The purpose of this study was to investigate the effects of dietary zinc on immune response in mice. Weanling male mice was placed individually in stainless steel cages and fed a zinc dificient diet and control diet. All mice were given deionized water ad libitum. The introduction of extraneous zinc was minimized in all cage by washing feed jars and water bottles sequentially with 4mM EDTA and conc-nitiric acid followed by deionized water. After 4 and 5 weeks of the diets, mice were immunized with lx 106 Naegleria fowleri intraperitoneally. Mice were weighed once a week. The results from this study are summarized as followed ; 1) Mice fed the zinc dificient diet showed growth retardation. After 3 weeks of diets, mean body weight of zinc deficient mice was 21.4g and that of control was 25.0g. This difference is singnificant statistically (p<0.01). The more time passed, the more remarkable difference was found. 2) The weigth of organs were measured on liver, kidney, spleen, thymus, heart, lung, brain. Difference in weight were observed only in liver and spleen. 3) Proliferative response of spleen cells of zinc deficient mice to con A was lower than that of control mice after one week on immunization(p<0.005). 4) Stimulation index was lower in zinc deficient mice to phytohemagglutinin after two weeks on immunization (p<0.05). 5) Blastogenesis of speen cells of zinc deficient mice to Naegleria fowleric lysate was lower after 10 days on immunization (p<0.05). 6) Immunoglobulin G antribody titers of zinc deficient mice sera by ELISA was lowered to control mice after 5 weeks on immunization (p<0.005).

Toxic waste disposal: Many people think that when toxic waste is dumped into the ocean or into the air, it disappears. This belief is incorrect. Rather than disappearing, it accumulates over time and slowly destroys the environment. Ultimately, it leads to the destruction of human race. Plasma is environmentally friendly: Plasma is environmentally friendly because it is created and disappears. When plasma is formed on the earth, you need certain conditions such as accelerating electrons by an electrical discharge or a particle accelerator. When this is gone, plasma completely disappears, leaving no impact on the environment. Plasmas produce radicals: Even if plasma density is low at atmospheric pressure, many radicals (excited states of molecules) are created. These radicals are chemically very aggressive. So instead of using harmful chemicals, plasma can be utilized for less of an impact on the environment. Plasma can reach very high temperatures: Plasma is also useful because when you control the density, you can easily reach high temperatures up to $5000{\sim}6000^{\circ}C$ at atmosphere pressure. Because of this heat and the chemical aggressiveness of the plasma, there are many green applications for plasma technology. Pulsed power technology: Pulsed electric field for extraction, drying and killing bacteria. Treatment of biological tissue by pulsed electric fields: Extraction of substances from cells: Sterilisation, Medical applications, Growth stimulation, Food preparation. Each application has its specialities, especially with respect to pulse shape and electric field strength.
