Studies on Incubator Hygiene IV

Studies of food hygiene and diarrhoeal disease.

Contamination of weaning foods and water with enteropathogenic micro-organisms has been recognised in the past, but its link with the development of diarrhoea by young children in developing countries is lacking. This may explain the unavailability of effective interventions to reduce the risk of diarrhoeal diseases from this contamination. The frequency of contamination of weaning foods with e...

Structural studies on human type IV collagen.

Type IV collagen was isolated from limited pepsin digests of human placenta by selective salt precipitation at acidic and neutral pH. The native protein was resistant to human skin collagenase but was cleaved by a rat mast cell protease. Molecular sieve chromatography of the reduced and alkylated material separated relatively homogeneous components of molecular weight 140,000 (140K) and 100,000...
