A number of eukaryotic expression vectors have been developed for use as DNA vaccines. They showed varying abilities to initiate immune responses;however, there is little data to indicate which of these vectors will be the most useful and practical for DNA vaccines in different species. This report examines the use of five expression vectors with different promoters and Kozak sequence to express the same hemagglutinin (HA) protein of an H6N2 avian influenza virus for DNA vaccination in chickens. Although intramuscular vaccination with seven DNA constructs elicited no or limited measurable H6 HA antibody responses in Hy-Line chickens, variable reduction in virus shedding for either oropharyngeal or cloacal swabs post-virus challenge were observed. This indicated that all DNA constructs generated some levels of protective immunity against homologous virus challenge. Interestingly, lower dose (50 or 100 μg) of plasmid DNAs consistently induced better immune response than higher dose (300 or 500 μg). In the transfection experiments there appeared to be a hierarchy in the in vitro expression efficiency in the order of pCAG-optiHAk/ pCAG-HAk > pCI-HAk > VR-HA > pCI-HA > pCI-neo-HA > pVAX-HA. Since the level of in vitro expression correlates with the level of immune response in vivo, in vitro expression levels of the DNA constructs can be used as an indicator for pre-selection of plasmid vaccines prior to in vivo assessment. Moreover, our results suggested that the Kozak sequence could be used as an effective tool for DNA vaccine design.

Previous research has documented that solid biomaterials such as charcoal or waste coffee and tea have been used to remove heavy metals from contaminated aqueous solutions through adsorption. However, these studies used very low heavy metal concentrations between 10 to 100 ppm. Recently published research work reported that extracts of edible plants and fruits were able to effectively remove lead from contaminated aqueous solution. This paper evaluates the ability of charcoal, un-brewed coffee and tea, fishbone, and caffeine to remove lead from contaminated aqueous solutions. The order of lead removal from 1300 ppm of lead solution is Charcoal (100%) > Tea (97%) > Coffee Ground (88%) > Instant Coffee (83.5%) > Coffee Bean (82%) > Fishbone (76%) > Caffeine (1.3%). These results clearly demonstrate that not all solid biomaterials can adsorb lead and that caffeine, a component of coffee and tea does not participate in the removal of lead from contaminated solutions. Furthermore, the results suggest that two possible processes may be involved in the reactions presented here: adsorption of lead by the solid substrates and precipitation of lead by the solubilized biochemical components of the substrates.

Due to the increasing burden on healthcare budgets of musculoskeletal system disease and injury, there is a growing need for safe, effective and simple therapies. Conditions such as osteoporosis severely impact onquality of life and result in hundreds of hours of hospital time and resources. There is growing interest in the use of low magnitude, high frequency vibration(LMHFV) to improve bone structure and muscle performance in a variety of different patient groups. The technique has shown promise in a number of different diseases, but is poorly understood in terms of the mechanism of action. Scientific papers concerning both the in vivo and in vitro use of LMHFV are growing fast, but they cover a wide range of study types, outcomes measured and regimens tested. This paper aims to provide an overview of some effects of LMHFV found during in vivo studies. Furthermore we will review research concerning the effects of vibration on the cellular responses, in particular for cells within the musculoskeletal system. This includes both osteogenesis and adipogenesis, as well as the interaction between MSCs and other cell types within bone tissue.

本文建立了一个描述造纸机流浆箱的数学模型及其自动调节系统的计算机模拟系统。利用这个模型及模拟系统能对各种流浆箱自动调节系统进行动态模拟和质量评估。对气垫流浆箱的四种不同调节方案,进行模拟及其结果的比较和评估后发现:方案一(用总压控制进浆量,用浆位控制空气流出量)优于方案二(用总压控制空气流出量,而用浆位控制进浆量),方案三(在方案一基础上增加了内溢流)更好;在方案四中,由于加入了浆速一网速比的串级调节系统,能有效地克服网速干扰对浆速-网速比及纸页定量的影响。
