From a pulpit or a platform even the most conscientious of speakers finds it very difficult to tell the whole truth. To Huxley's famous list of those prone to oversimplification given an appropriate platform, I fear we must add the occasional academic adminis...

The nature of digitoxin fixation in isolated hearts was studied with C14 labelled digitoxin. Fixation wvas greatest in the early stages of perfusion. The amount of drug fixed was measured directly. A considerable percentage cf the digitoxin in cardiac muscle was changed to other substances. These substances are more firmly bound to the heart than digitoxin. T HE preparation of pure, randomly la...

I n my personal series of 3006 children with congenital hand abnormalities, the most common defect was extra digits (528 cases), next was webbed fingers (429 cases), and third was abnormalities of the little finger (354 cases). Any of the digits of a newborn may show deviations in alignment to the palm. However, it is the ulnar side of the hand, and usually the little finger, that most commonly...

Objectives. Quantitative cytology by image-analysis techniques enables objective interpretation of nuclear features in light microscopic images. QUANTICVT, a quantitative karyometric cytology system, was used in the follow-up of patients with superficial bladder cancer. Methods. From 1992 to 1995, 41 37 samples from 1412 patients were obtained. At 1 -year follow-up after the initial bladder was...

Surely the key to Alchemy has been lost for a very long time-if there ever existed anyone who possessed or was even seriously believed to possess it. What we can do is to survey its literary and ideological sources and thereby demonstrate the ever-recurring 'motives' of a 'secret' and 'sacred' tradition of venerable age.

It was hypothesized that nutrient removal from waste­ water could be achieved by using methane oxidizing bacteria (melhan­ otrophs). Because methane is inexpensive. it can be used as an energy source to encourage bacterial growth to assimilate nitrogen and phos­ phorus and other trace elements. This initial feasibility study used syn­ thetic nutrient mixtures and secondary sewage effluent as fe...
