| breast volume measurement of 598 women using biostereometric analysis. | a study of the volumes of the right and left breasts of 598 subjects was undertaken using biostereometric analysis. this measurement uses close-range stereophotogrammetry to characterize the shape of the breast, and is noncontact, noninvasive, accurate, and rapid with respect to the subject involvement time. using chi-square tests, volumes and volumetric differences between breast pairs were compared with handedness, perception of breast size by each subject, age, and menstrual status. no signif ... | 2009 | 2729845 |
| validity of ear oximetry in clinical exercise testing. | because of suspicion that the ear oximeter might measure the oxyhemoglobin saturation of arterial blood inaccurately during heavy exercise, we made concurrent ear oximetric and blood measurements on 14 consecutive patients with arterial catheters during clinical exercise tests. after correcting for carboxyhemoglobin, the estimated and measured values for the oxyhemoglobin saturation of the blood agreed well, as did resting ear and blood values; however, during heavy exercise, ear oximetric value ... | 2012 | 3816311 |

| opposite effects of one and three injections of cortisone or thyroxine on intestinal lactase activity in suckling mice. | a single injection of cortisone or thyroxine to 8-day-old suckling mice initiates a temporary decrease of lactase activity. on the contrary, 3 injections of cortisone or thyroxine provoke a significant increase of lactase activity. it appears that the mechanism which controls the postnatal development of lactase in suckling animals is more complex than expected. | 1998 | 108133 |

| effects of combination therapy with pirenzepine and famotidine on tetragastrin-stimulated gastric secretion in humans. | to determine the combined effects of the h2-receptor antagonist famotidine (fam) and m1-receptor antagonist pirenzepine (pz) on tetragastrin-stimulated acid production, 10 mg of fam was intravenously injected into 6 healthy volunteers, alone and in combination with 20 mg of pz. physiologic saline was administered separately for control purposes. compared with physiologic saline, both fam and the fam + pz combination significantly reduced gastric secretion, acidity, acid output, and pepsin secret ... | 2007 | 1783354 |
| the effect of progestins on the mitotic activity of uterine fibromyomas. | previous studies have shown increased mitotic activity in uterine fibromyomas in patients using exogenous hormones. this study has compared the mitotic activity of fibromyomas in three groups of patients. the first group was using a progestin-only preparation (usually depo-medroxyprogesterone acetate). the second group of age-matched controls had never used any exogenous hormone. the third group of patients was using a combined estrogen/progestin oral contraceptive. the results show that patient ... | 2012 | 3926664 |

| correction of fallot's tetralogy after palliative operations. | during the period 1960 to 1978, 98 patients underwent intracardiac repair of fallot's tetralogy after palliative operations. preoperative symptoms were cyanosis, dyspnea, increased fatigue with squatting and hypoxic spells. the hemoglobin concentration varied from 19 to 22 g/100 ml. at correction only 65 of 95 shunts were patent and needed surgical closure. seventeen early deaths occurred (19%), the main causes being cardiac failure and arrhythmia. one patient died 3 years after correction from ... | 2000 | 87399 |
| the attack mechanism of an exo-1,3-beta-glucosidase from basidiomycete sp. qm 806. | the attack mechanism of a purified exo-1,3-beta glucosidase (1,3-beta-d-glucan glucohydrolase, ec 3.2.1.58) was investigated by using as a substrate a mixture of two structurally characterized periodate-oxidized and reduced unbranched 1,3-beta-d-glucans which differed only at the reducing terminal. the substrates, derivatives of laminarin, were altered only at the terminals due to resistance of the internal (1 leads to 3)-linked glucosyl residues to periodate oxidation. each glucan has only a si ... | 2003 | 164221 |
