The lethal effects of ionizing radiations on cells may be either genetic or nongenetic in origin and, if genetic, may be classified as dominant or recessive. If the radiosensitivity of an organism depends on its ploidy, it may be inferred that genetic damage is involved (1). Where such a dependence has been found, the relative importance of recessive and dominant lethal effects appears to accou...

We investigated Legionella contamination in bath water samples, collected from 68 bathing facilities in Japan, by culture, culture with amoebic co-culture, real-time quantitative PCR (qPCR), and real-time qPCR with amoebic co-culture. Using the conventional culture method, Legionella pneumophila was detected in 11 samples (11/68, 16.2%). Contrary to our expectation, the culture method with the ...

Poultry meat has been identified as one of the principal foodborne sources of Salmonella. In this preliminary study the prevalence of Salmonella spp. and its typhimurium serovar contamination of broiler carcasses, were determined. Using the rinse test method, numbers of 60 samples, representing 20 broiler flocks, were collected from poultry carcasses after the chilling stage in the processing l...

In this research, the survival of probiotic microorganisms in yogurts stored at room temperature (cold chain interruption conditions) was studied. Milk inoculated with yogurt bacteria (mixed culture of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus) and a single probiotic culture (L. acidophilus LA-5 or Bifidobacterium lactis Bb-12 or L. rhamnosus HN001 or L. paracasei...

this study was performed to detect cultivable canine gastric helicobacter-like organisms (ghlo’s) and to evaluate their sensitivity to common antibiotics in two groups of naturally infected dogs (pets and stray dogs). gastric samples were taken from the body and antrum of 30 pets and 30 stray dogs. from each part of canine gastric mucosa, four gastroscopic samples were used for impression smear...

Endocervical swabs from 212 women and urethral swabs from 100 men were tested by the routine methods for McCoy cell culture and simultaneously by a novel enzyme amplified immunoassay test to detect chlamydia antigen. Overall correlation of the amplified test with culture was 96.5%. The test proved to be a suitable screening procedure for genital chlamydial infection, particularly for large numb...

The purpose of this communication is to describe a rack which permits the simultaneous handling of 24 culture vials for purposes of plaque assays of viruses, interferon assays, cloning of cells, and other related procedures in cell culture. In this laboratory, the rack has been found to decrease significantly the time and effort required for the manipulation of moderate to large numbers of cult...

Numerals are used in a variety of tasks, both science and everyday life. Using numbers, we record the results calculations (twenty, forty years), determine order between elements plural (the first speaker, millionth person to live), express measurement something (a mile half). In addition, numeric characters can be instead words, letters, for example, encode text. Chinese culture is recognized ...

Y-27632 is a well-known inhibitor of the Rho-associated coiled kinase (ROCK) and has been shown to significantly improve the culture of a variety of multipotent stem cell types. However, the effects of Y-27632 on the expansion of adult human adipose-derived stem cell (hADSC) cultures remain to be established. Here, we aimed to characterize the effects of Y-27632 on the culture of hADSCs. Adult ...
