There is a controversy regarding the mechanism of phase separation in highly charged macroion systems. Volume-term (VT) theories propose that the transition is due to a spinodal instability sensitive only by the microions, the Sogami-Ise theory gives an attractive tail in the pair interaction potential, which promotes the formation of ...

A collegiate freshman golfer was hypertensive at her preparticipation physical exam (PPE). Further investigation revealed coarctation of the aorta with secondary hypertension that had been asymptomatic. The PPE is a good forum for hypertensive screening because it may be one of the few times an apparently healthy adolescent is seen ...

The 1996 "Update on the 1987 Task Force Report on Blood Pressure in Children and Adolescents" adopted the fifth Korotkoff phase to define diastolic blood pressure and added height, in addition to age and gender, to develop new standards for blood pressure (BP) in children. The present study was performed ...

A fast screening method for the determination of the dissociation constants (pKa) of acidic, basic, and multivalent compounds was developed by using pressure-assisted capillary electrophoresis (PACE). External air pressure was applied to shorten the analysis time. The separation efficiency decreases as air pressure increases. However, it was found that air ...

INTRODUCTION: Glucocorticoid-remediable aldosteronism (GRA) is a rare inherited cause for hypertension associated with a significant morbidity and mortality at an early age. Individuals with this abnormality frequently present with severe hypertension which is resistant to standard antihypertensive therapy, a strong family history of hypertension, intracranial haemorrhage, and sporadic hypokalaemia. However ...

There is a growing body of evidence suggesting that calcium channel blockers (CCB) exert beneficial effects on kidney transplant survival. However, it is not completely understood if these agents act independently of blood-pressure reduction. In the present study, the 5-yr follow-up of 45 kidney transplant recipients receiving CCB during the ...

Kidney transplant recipients as well as patients on hemodialysis frequently share an increased risk of cardiovascular diseases. Besides other factors, modulations in central neural blood pressure regulation have to be considered as a pathogenetic factor. In this study, baroreceptor function as a possible modulator of blood pressure and the activity ...

As the interlobular arteries of the ageing kidney progressively accumulate intimal fibroplasia, these fibroplastic changes appear to introduce strictures upon the interlobular arteries. These strictures are expected to generate nephron heterogeneity, which is a uniquely disturbed setting peculiarly suited to sustaining both high and low renin forms of hypertension. Fibroplastic ...

As a basis for chronobiologic analyses and thereby for screening deviant blood pressure, measurements are advocated, preferably with ambulatorily functional instrumentation at half-hour intervals around-the-clock for an initial span of 7 days. When only manual instrumentation is available, 3-hourly measurements during waking and one measurement, preferably by a companion, around ...

In clinical trials that study people with a continuous measure defined categorically, even repeated measurements within a visit and over successive visits do not prevent error-free classification. We describe the design of a screening procedure for the Systolic Hypertension in the Elderly Program (SHEP), a randomized clinical trial designed to ...

We developed an in vitro human kidney model to study the intrarenal pelvic pressures generated during percutaneous nephroscopy. Higher intrapelvic pressures were associated with nephroscopy sheaths of smaller caliber and greater length. In addition, the position of the sheath within the kidney markedly influenced intrapelvic pressure. The results of this ...

1. Disturbances of the blood pressure regulation, probably due to dysfunction of the autonomic nervous system, are well known complications in chronic renal failure. Haemodialysis and transplantation have been reported to ameliorate nerve dysfunction. 2. In this study, the function of the blood pressure control was investigated in kidney transplant ...

The National Blood Pressure Survey aimed to determine blood pressure levels among Omanis > or = 18 years, study the epidemiological factors most related to blood pressure and suggest a programme for the management and control of hypertension in Oman. Of the 4732 people screened, 1278 (27.01%) had high blood ...

Hypertension in children has received minimal attention in the dental literature; this may be the result of comparatively low interest in the subject by the medical community. It is now believed that the processes causing cardiovascular disease morbidity and mortality begin early in life. The implication for prevention is that ...

The ankle-arm blood pressure index (AAI) is seldom used to screen for atherosclerotic diseases other than lower extremity arterial disease. This study was conducted to investigate whether the AAI can be used as a screening test for atherosclerotic diseases in general. The subjects were 446 male workers in a copper ...

The association of cocaine and acute hypertension is well known; however, cocaine use has not generally been linked to chronic hypertension. We hypothesized that chronic use of cocaine over time would increase the prevalence of hypertension and that cocaine induced vasoconstriction would result in urine protein leakage, manifested by microalbuminuria. ...

Early repair of coarctation of the aorta (COA) is associated with few perioperative complications and better long-term outcome. Therefore, early detection and treatment of COA patients is extremely desirable. The aim of this study was to review our referral system, the effectiveness of neonatal screening examination, and orient physicians about ...

Previous studies suggest that older honey bee workers possess an inhibitory signal that regulates behavioral development in younger bees. To study how this inhibitor is transmitted, bees were reared for 7 days in double-screen cages, single-screen cages, or unrestricted in a typical colony (control bees). Double-screen cages prevented physical contact ...
