Engberg et al. (2) compared selective media and filtration for the efficient isolation of campylobacteria from stools. Since 1977, we have routinely isolated campylobacters from the diarrhetic stools of pediatric patients at the Red Cross Children’s Hospital in Cape Town, South Africa. In 1990, the use of antibiotic-containing plates was discontinued, and the Cape Town protocol, the first to co...

Human T-cell growth factor (TCGF), a mitogenic protein that appears in the media of cultured lymphocytes after phytohemagglutinin-stimulation, has been purified more than 400-fold from serum-free conditioned media by using a sequence of ion exchange chromatography and gel filtration. The purified growth factor elutes as a broad peak from DEAE-Sepharose, focuses diffusely at a pH of about 6.8 on...

BACKGROUND AND PURPOSE We aimed to clarify the association of chronic kidney disease (CKD) with carotid atherosclerosis and the impact of CKD on carotid atherosclerosis according to blood pressure categories in an urban general population. METHODS We studied 3466 Japanese individuals (35-93 years old) in the Suita Study. Carotid atherosclerosis was expressed as the maximum carotid intima-medi...

india is one of the largest producers of onion in the world producing over 13,920,000 metric tons. storage is a major problem which leads to spoilage, and microbes play an important role in the spoilage. in this present study, biotechnologically important strains have been isolated from the spoiled onions by using appropriate enriched media. two potential strains were isolated and a brief compa...

Direct flow (sometimes called “dead end”) filtration is applied when all the fluid to be filtered is driven, typically in industrial applications due to a supply pressure, in a direction perpendicular to a filtering surface; few applications are done by gravity feed. Contaminants are captured within the filtration media or build up on the surface, causing the differential pressure across the fi...

Pumice and the Moringa oleifera (MO) seed were investigated as alternative natural materials for drinking water treatment based on problems identified at the Stretta Vaudetto water treatment plant in Eritrea. Lab and pilot scale studies showed that pumice was a suitable alternative material for dual media filtration. Conversion of the sand filters at Stretta Vaudetto to pumice-sand media would ...

Collaboration among distributed workgroup members is hampered by the lack of good tools to support informal interactions. These tools either fail to provide teleawareness or enable smooth transitions into and out of informal interactions. Video media spaces—always-on video links—have been proposed as a solution to this problem. However, the “always-on” nature of video media spaces results in a ...
