Question: Abstract: A 52K glycoprotein is secreted by human breast cancer cells in culture after estrogen stimulation. Using monoclonal antibodies, we have quantitated and characterized the corresponding proteins of the cell compartment. Using pulse-chase experiments, we have shown that about 40% of the 52K protein is secreted, the majority being successively processed into a 48K and a 34K protein. This last protein is very stable. The processing is inhibited by lysosomotropic agents and leupeptin, suggesting that it occurs in acidic vesicles, such as lysosomes or endosomes. Estradiol increased the intracellular level of immunoreactive 52K related proteins by 4-fold. Its effect is, however, more obvious in the medium, since there is a constitutive level in the cell. The stimulatory effects of estradiol on [3H]mannose and [35S]methionine incorporation into these proteins were similar and the endoglycosydase H sensitivity of the proteins was not altered, suggesting that estradiol did not modulate the glycosylation step. Antiestrogens did not stimulate synthesis and glycosylation of the 52K related proteins. Estradiol also increased the stability of the 52K precursor as well as that of total proteins. We conclude that the secreted 52K protein is the precursor of two cellular proteins of 48K and 34K. Estradiol stimulates both the intracellular accumulation of these proteins and the secretion of the precursor.

Question: Abstract: The results of forty core-decompression procedures that were performed for ischemic necrosis of the femoral head in thirty-one patients over a four-year period were retrospectively reviewed to ascertain the effectiveness of the procedure. The data did not support the published rates of success of the procedure for Stage-1 and Stage-2 lesions. With a mean length of follow-up of eighteen months, 60 per cent of the hips that had a decompression prior to collapse of the femoral head demonstrated progression of the lesion and were judged to be a failure by clinical or radiographic criteria. Computerized tomographic scans and magnetic resonance imaging proved to be 100 per cent sensitive for diagnosis in preoperative testing; isotopic bone-scanning was less sensitive (80 per cent). Functional intraoperative testing by the method of Ficat did not provide added sensitivity or specificity to the results of the preoperative bone scan. A postoperative or intraoperative fracture occurred in four hips, for an incidence that exceeded any in previously published reports. We concluded that core decompression should be considered a relatively ineffective procedure with significant morbidity.

Question: Abstract: Despite the clear-cut result of the Australian Therapeutic Trial in Mild Hypertension, which demonstrated prospectively the benefit of treatment of diastolic blood pressure in the range of 95 to 109 mm Hg, a retrospective analysis that classified subjects by the average diastolic pressure level attained during the trial purported to show an absence of treatment benefit at lower average diastolic pressures and a negative treatment effect at higher levels. However, the method of classification by average attained diastolic pressure introduced substantial selection bias, invalidating the retrospective analysis and rendering as spurious both the deleterious treatment effect and its lack of efficacy at lower diastolic levels.
