| serum squamous cell carcinoma antigen in gynecologic malignancies with special reference to cervical cancer. | squamous cell carcinoma (scc) antigen was measured by double-antibody radioimmunoassay in the sera of 113 patients with gynecologic malignancies and 30 controls. the mean serum scc antigen level was 9.24 ng/ml in those with cervical squamous cell carcinoma, 2.15 ng/ml in those with other gynecologic malignancies, and 1.25 ng/ml in controls. with a cutoff value of 2.23 ng/ml (2 sd above the mean of the control group), the rate of scc antigen elevation was 54% in cervical cancer (78), 14% in vulva ... | 2008 | 2592943 |

| exercise capacity following pulmonary rehabilitation in the elderly. | pulmonary rehabilitation has proven beneficial for patients with chronic airway obstruction. in this study, the authors evaluate the effect of rehabilitation in elderly patients. results show that the change in exercise capacity was not related to the patients' age, and suggest that age alone should not be an exclusionary criterion. | 2008 | 2811833 |
| near infrared spectrometry for faecal fat measurement: comparison with conventional gravimetric and titrimetric methods. | this investigation was aimed at comparing a new method for measuring faecal fat excretion, carried out with a semi-automated instrument by using near infrared analysis (nira), with the traditional titrimetric (van de kamer) and gravimetric (sobel) methods. near infrared analysis faecal fat was assayed on the three day stool collection from 118 patients (68 chronic pancreatitis, 19 organic diseases of the gastrointestinal tract, 19 alcoholic liver disease, 12 functional gastrointestinal disorders ... | 2008 | 2583563 |

| intraperitoneal therapy with interferon-alpha in capd patients with relapsing bacterial peritonitis. | in capd patients with relapsing bacterial peritonitis who do not benefit from intraperitoneal therapy with igg (igg nonresponders), the authors demonstrated that peritoneal macrophages are deficient in igg fc receptors (fcr) and, therefore, unable to kill bacteria, independent of the levels of the opsonic molecule igg in the peritoneal dialysis effluent (pde). because previous studies showed that interferon-alpha (ifn-alpha) is able to increase in vitro the number of pm0 igg fcr in capd patients ... | 2008 | 2597493 |

| tertatolol in hypertension. long-term therapy in 2,338 patients. | tertatolol has been studied in 2,338 patients with mild to moderate hypertension over a one year period. tertatolol (t) was initiated alone (5 mg once daily) and if satisfactory control of blood pressure (bp) (diastolic bp less than 95 mm hg) was not achieved, treatment was adapted at the third or sixth month either by increasing the dosage (heart rate greater than 70 beats/min), or by adding a potassium-sparing diuretic (heart rate less than or equal to 70 beats/min). blood pressure normalizati ... | 2008 | 2573378 |
| [seminoma in the undescended testis]. | maldescend testes are predisposed to tumor degeneration from embrional germinal dysgenesis, the cause of cryptorchidism. the risk of carcinogenesis is thirty to fifty times greater than in normal descended testes. the histologic features of this tumor type and its treatment do not differ from those of normotopic tumors. | 2008 | 2573318 |
| [uterine rupture. apropos of 31 cases seen at the hospital center of libreville (gabon)]. | the authors report 31 cases of rupture of the uterus at the hospital of libreville-gabon. the frequency is 1.4/1,000 deliveries. the usual etiological factors are found: malformations of the uterus, obstetrical maneuvers, mechanical dystocias, use of oxytocics, scars of caesarean section. the clinical characteristics are those previously described. there were two maternal deaths and 17 fetal deaths. these figures emphasize the progress accomplished and to come. | 2008 | 2740710 |
| what do we measure by a luminol-dependent chemiluminescence of phagocytes? | the review presents a survey of published findings concerning the mechanism of luminol-dependent chemiluminescence in biological systems. the potential of various oxygen species (superoxide anion, hydrogen peroxide, hydroxyl radical) to react with luminol is discussed. the ability of commonly used enzymes (superoxide dismutase, catalase), inhibitors, and oxygen radical scavengers to discriminate between individual oxygen species is assessed together with the potential of a variety of substances ... | 2008 | 2546866 |
| tropical fish medicine. evaluating water problems. | this article presents some of the basic concepts involved in managing water in tropical fish aquariums. the intent is not to address all problem situations and their solutions, but to inform the practitioner of the interactions between fish, water, and container and the complicated nature of successfully diagnosing water problems in the home aquarium. the important variables in water quality as they relate to fish health are presented. potential problems from source water, inadequate biological ... | 2008 | 3259750 |
| serum fatty acid profile of elderly tube-fed men in a nursing home. | severely dependent tube-fed elderly men with dementia in this va nursing home are nourished exclusively with isocal, which provides only four fatty acids in amounts over 1% of the total (palmitic, oleic, linoleic, and alpha-linolenic). it has not been proven that the frail elderly can efficiently convert linoleic to arachidonic acid, and alpha-linolenic to eicosapentanoic and docosahexaenoic acids. therefore, we compared the serum profile of fatty acids in six of the tube-fed elderly men with th ... | 2008 | 2493045 |

| the effect of captopril on cutaneous blood flow in patients with primary raynaud's phenomenon. | fifteen patients with primary raynaud's phenomenon received captopril 25 mg or placebo, three times daily for 6 weeks, in a randomized double-blind cross-over study. compared with placebo, captopril produced a significant improvement in cutaneous blood flow but did not alter the frequency or severity of attacks of raynaud's phenomenon. | 2008 | 3322358 |
