Care of the diabetic child in the community.

Brief admission of the new diabetic child and of a parent to an enlightened hospital for stabilisation, preliminary education, and familiarisation with hospital and community staff is well worth while. The greater the demand for constant control of the highest quality, the greater the need for a close understanding of the psychosocial factors concerned and for clinical skill. The nature of the home and the family relationships should in theory be available from the child''s general practitioner at the time of the first referral since he has so much information about the whole family. With the virtual disappearance, however, of mutual consultation in the patient''s home in many places, the opportunity for oral communication has declined, and availability on the telephone is not always easy. The busy general practitioner (far less an unknown physician from a deputising service without access to the records) has little time to write a comprehensive letter. In practice a relatively small hospital-based mobile team of specially experienced sisters who are keen to communicate in the home, the GP''s surgery, and the school makes a major contribution to the diabetic care of a young population vulnerable to major handicap in what should be the prime of life. Their cost effectiveness may be difficult to prove but it is not at all in doubt--especially when the sisters as in this area deal in the community with a wider range of chronic illnesses and handicaps in children.     

Methimazole and generation of oxygen radicals by monocytes: potential role in immunosuppression.

A study was conducted investigating the possibility that the immunosuppressive action of methimazole (the active metabolite of the antithyroid drug carbimazole) might be due to an effect on the production of oxygen radicals by monocytes. Techniques comprised measurement of luminol dependent chemoluminescence in monocytes and a spectrophotometric assay for production of hydrogen peroxide. The results showed definite inhibition of formation of oxygen radicals by resting and stimulated monocytes, which may explain the immunosuppressive action of the drug in Graves'' disease. The findings also suggest that the formation of oxygen radicals and the initiation of the immune response may be closely related.     

A Study in Neo‐conservative Populism: Richard Trudgen's Why Warriors Lie Down and Die

First appearing in 2000, and with 20,000 copies sold as it entered its sixth printing in 2004, Richard Trudgen's Why Warriors Lie down and Die is a minor publishing phenomenon. Although scholarly forums have generally ignored the book, Christian media outlets, the popular press and neo‐conservative political activists have enthusiastically received and promoted it. An examination of the merits of Why Warriors Lie down and Die suggests that its popularity is only partly explained by original observations or insights on the part of the author. The most important explanation, and implication, of the book's remarkable take‐up lies in the opportune way in which it corresponds with now ascendant neo‐conservative political perspectives on indigenous policy.     

Stereospecificity and requirements for activity of the respiratory NADH dehydrogenase of Escherichia coli

The respiratory NADH dehydrogenase of Escherichia coli has been further amplified in vivo by genetic methods. The enzyme, a single polypeptide of Mr 47 200 of known amino acid sequence [Young, I. G., Rogers, B. L., Campbell, H. D., Jaworowski, A., & Shaw, D. C. (1981) Eur. J. Biochem. 116, 165-170], constitutes 10-15% of the total protein in the amplified membranes. In situ in the membrane, the enzyme contains 1 mol of FAD/mol of subunit and has a specific NADH:ubiquinone-1 oxidoreductase activity of approximately 1100-1200 units mg-1 at 30 degrees C, pH 7.5. The purified enzyme contains phospholipid, which remains closely associated with it during gel filtration on Sephacryl S-300 in the presence of 0.1% (w/v) cholate at low ionic strength. Under these conditions the enzyme is extensively aggregated (apparent Mr greater than 10(6]. This procedure yielded enzyme with a specific activity of 980 units mg-1, similar to the value observed in the membrane. This preparation contained less than 0.1 mol of Fe/mol of enzyme, confirming that Fe is not involved in reduction of ubiquinone 1 catalyzed by the enzyme. Neutron activation analysis of purified enzyme has demonstrated the absence of 35 trace elements including Se, Zn, Mn, Co, W, Cu, and Fe. The enzyme polypeptide, prepared completely free of phospholipid, FAD, and ubiquinone by gel filtration in the presence of sodium dodecyl sulfate, has been reactivated. The results show that the only components necessary for catalysis of ubiquinone-1 reduction by NADH in this system are the enzyme polypeptide, FAD, and phospholipid.(ABSTRACT TRUNCATED AT 250 WORDS)
