In this study, expanded human trial with M, Gerbil kidney tissue culture inactivated HFRS vaccine was carried out and neutralizing antibody response was assessed by plaque reduction neutralization(PRNT) and CPE neutralization(CPENT) methods. According to the data of all 74 person immune sera assayed by the two methods, the rates of seroconversion and GMT tesed by CPENT were significantly higher than that by PRNT. Several vaccinating groups were studied and the neutralizing antibody levels were as follows: v...

THERE IS AN IMPORTANT NEED IN THE STUDY OF TOXICOLOGY OF TOPICALLY-APPLIED AND ENVIRONMENTAL AGENTS FOR AN IN VITRO SYSTEM TO STUDY THEIR TOXIC EFFECTS ON SKIN. THE IN VITRO SYSTEMS HAVE THE BENEFIT OF ALLOWING STUDY OF A LARGE VARIETY OF SUBSTANCES ON AN INDIVIDUAL SPECIMEN. AN IN VITRO SYSTEM CONTAINING ALL THE COMPONENTS OF SKIN ALLOWS STUDIES TO DETERMINE THE EFFECTS OF AGENTS ON THE VARIOUS COMPONENT CELL TYPES AND CELL INTERACTIONS. THIS IS PARTICULARLY THE CASE IN THREE-DIMENSIONAL HISTOCULTURE SYSTEMS. WE DEVELOPED A GEL-SUPPORTED, THREE-DIMENSIONAL HISTOCULTURE SYSTEM THAT ALLOWS THE INTACT GROWTH AND TOXICITY TESTING OF ALL COMPONENTS OF MOUSE SKIN, INCLUDING KERATINOCYTES, DERMAL FIBROBLASTS AND HAIR FOLLICLE CELLS AS WELL AS HAIR, FOR PERIODS OF 10 DAYS OR MORE (LI, L., MARGOLIS, L.B.

Organ cultures are practical tools to investigate regenerative strategies for the intervertebral disc. However, most existing organ culture systems induce severe tissue degradation with only limited representation of the in vivo processes. The objective of this study was to develop a space- and cost-efficient tissue culture model, which represents degenerative processes of the nucleus pulposus (NP). Intact bovine NPs were cultured in a previously developed system using Dyneema jackets. Degenerative changes in the NP tissue were induced either by the direct injection of chondroitinase ABC (1-20 U/mL) or by the diffusion of interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) (both 100 ng/mL) from the culture media. Extracellular matrix composition (collagens, proteoglycans, water, and DNA) and the expression of inflammatory and catabolic genes were analyzed. The anti-inflammatory and anti-catabolic compound epigallocatechin 3-gallate (EGCG, 10 µM) was employed to assess the relevance of

In recent years, advances in plant genetic engineering have opened new avenues for crop improvement and various plants with novel agronomic traits have been produced. The success of plant genetic engineering relies on several factors which include an efficient tissue culture system, for regeneration of plants from cultured cells and tissues (Pua et al. 1996). Shoot generation and rooting are important in the realization of the potential of the cell and tissue culture techniques for plant improvement (Purnhauser et al. 1987). Silver ions in the form of nitrate, such as AgNO3, play a major role in influencing somatic embryogenesis, shoot formation and efficient root formation which are the prerequisites for successful genetic transformation (Bais et al. 1999; Bais et al. 2000a; Bais et al. 2000b; Bais et al. 2001a; Bais et al. 2001b; Bais et al. 2001c). Silver ions are also employed in the form of silver thiosulphate in several tissue culture studies (Eapen and George, 1997).. Ethylene is ...

Some of the compounds in the active fraction of ultrafiltrates of chick embryo extract have been identified as taurine, serine, glutamic acid, xanthine, uracil, glucose-6-phosphate, glucose, ferrous iron, and inorganic phosphate.. Based on the identity of these compounds a synthetic replacement for the ultrafilterable portion of chick embryo extract has been devised. There is an additional nutritional requirement that can be met by vitamin B12. Folic acid appears to be beneficial to the system though the requirements of this or any of the above compounds except vitamin B12 remain for future research. The low nitrogen content of the isolated fraction and the synthetic mixture suggests that the main nutrition of chick cells in roller tube cultures is derived from the non-dialyzable portion of the medium.. ...

An ASU Biodesign Institute team has reported their latest advancement in 3-D intestinal model development. The new study, a collaboration between Arizona State University and NASAs Johnson Space Center, was led by Cheryl Nickerson, a researcher at ASUs Biodesign Institute and professor in the School of Life Sciences. Their united goal is to develop more realistic models of intestinal tissue to thwart Salmonella, a leading cause of food poisoning and systemic disease worldwide with many varieties causing severe and sometimes fatal infections with an economic impact in the billions of dollars.

A procedure has been developed for the determination of the concentration of infective Newcastle disease virus (NDV) based on the enumeration of singly infected and distributed HeLa cells which are visualized by staining with fluorescent antibody. Infective virus assayed by the fluorescent cell-counting procedure is expressed in terms of cell-infecting units (CIU).. Adsorption of NDV to HeLa cell monolayers reached a plateau 1 to 1.5 hours after inoculation of coverslip cultures, and 12 per cent of the infective particles inoculated failed to adsorb. The half-life of NDV in protein-free Eagles medium at 37°C. was 2.1 hours. There was a linear relationship between virus concentration and the number of infected cells. The coefficient of variation of the mean of replicate determinations of infective NDV was 8.2 per cent. The distribution of single infected HeLa cells in the monolayer corresponded to the Poisson distribution. With NDV the cell-infecting unit (CIU) determined in HeLa cells is ...

The present invention relates to an improved three-dimensional cell culture system in which cells are grown on a three-dimensional matrix while cycling the cultures between metabolically favorable and metabolically unfavorable (but noncytotoxic) conditions. The invention is based, at least in part, on the discovery that cycling the cultures in this manner optimizes the formation of extracellular matrix and produces an overall structure that more closely resembles naturally occurring tissue.

Besides the intended effects that give a genetically modified (GM) plant the desired trait, unintended differences between GM and non-GM comparable plants may also occur. Profiling technologies allow their identification, and a number of examples demonstrating that unintended effects are limited and diverse have recently been reported. Both from the food safety aspect and for research purposes, it is important to discern unintended changes produced by the transgene and its expression from those that may be attributed to other factors. Here, we show differential expression of around 0.40% transcriptome between conventional rice var. Senia and Senia-afp constitutively expressing the AFP antifungal protein. Analysis of one-fifth of the regulated sequences showed that around 35% of the unintended effects could be attributed to the process used to produce GM plants, based on in vitro tissue culture techniques. A further ∼15% were event specific, and their regulation was attributed to host gene ...
