Human amnion tissue is readily available to most laboratories as a source of cells for tissue culture studies. It has proved to be a useful tool in the field of virus research, and it offers impor tant potentials in the field of cancer research as a source of normal human cells easily obtained in primary cultivation. Many investigators have been concerned with the problem of malignant propertie...

Respiratory syncytial virus (RSV) is an important childhood pathogen of acute lower respiratory infections in developed and developing countries. The molecular epidemiology of RSV in India is largely unknown. The present study was undertaken to standardize and evaluate reverse transcription-PCR (RT-PCR) for the rapid and simultaneous detection of RSV groups A and B in clinical samples and to st...

This paper takes a comparative approach to early farming, arguing that bioarchaeological work on Neolithic Europe can inform understanding of earlier cultivation and herding in the Near East, where the ‘package’ of crops and livestock emerged in the PPNB period. Evidence for intensive cultivation (‘garden agriculture’) integrated with small-scale herding is outlined for south-east and central E...

Evidence is accumulating that Mycobacterium leprae is probably a microbe­ dependent microbe. l O1 3 The first report that multiplication of M. leprae was promoted by a growth factor of mycobacterial origin was proposed by Twort l 9 in 1 9 1 0 , two years before the discovery of the cultivation of 'lohne's bacilli' in media enriched with heat-killed mycobacteria . 2o The growth factor was identi...

Herpes simplex virus (HSV) establishes productive (lytic) infections in nonneuronal cells and nonproductive (latent) infections in neurons. It has been proposed that HSV establishes latency because quiescent neurons lack cellular factors required for productive infection. It has been further proposed that these putative factors are induced following neuronal stress, as a requirement for HSV rea...

Increased droughts in southern Africa have noticed some appreciation of the role that partial wetland cultivation can play to address household food security. This has also witnessed some indication of possible relaxation of wetland cultivation restrictive policies in Zimbabwe. However, the general perceptions of society towards wetland cultivation remain unclear and critically important for po...

Tea, a beverage produced by steeping processed top leaves and buds of the tea plant in freshly boiled water, originated in China 2700 BC, but its medicinal properties were know much before that. China was the first country to cultivate tea. In Japan the cultivation began about 200 AD. The use of tea later spread to the other Asian countries. Tea cultivation in India was suggested as early as 17...

urea is the most common form of nitrogen fertilizer used in sugar beet cultivation. urea has a high solubility and its losses are high and consequently its efficiency is low. it is supposed that urea solubility can be limited and its efficiency can be increased by using slow-release nitrogen fertilizers. by conducting an experiment in three important sugar beet cultivation areas of khorasan pro...
