PURPOSE The purpose of this study was to evaluate the effect of pharmacologic pupillary dilatation on anterior chamber depth (ACD) and anterior chamber angle (ACA) in eyes with exfoliation syndrome (XFS). METHODS Thirty-six eyes of 36 patients with XFS were evaluated with slit-lamp examination, Goldmann applanation tonometry and ultrasound biomicroscopy (UBM) under standard light conditions. ...

Time lags in receiving data from long-standing, large federal surveys complicate real-time estimation of the coverage effects of full Affordable Care Act (ACA) implementation. Fast-turnaround household surveys fill some of the void in data on recent changes to insurance coverage, but they lack the historical data that allow analysts to account for trends that predate the ACA, economic fluctuati...

We examined sera from sixdifferent groupsofpatientsfor CK-MB activity by means of two commercially available tests,an immunoinhibitionmethod (E. Merck) and the CK-MB test as used with the aca (Du Pont). In the first group of patients (suspicion of myocardial infarction) the correlationbetween the two methods was good: r = 0.9191, y = 1.068x0.888, = 18.7 U/L, = 19.0 U/L. Inthe second group,patie...

AIMS To determine whether the presence of anticardiolipin antibodies in patients with suspected myocardial infarction is predictive of complications during hospital stay or after discharge. METHODS Anticardiolipin antibodies were serially measured in a cohort of 111 patients, from the time of admission to the coronary care until till eight weeks after discharge. Associations with fatal and no...

We have shown that the tetrapeptide N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) inhibited endothelin-1 (ET-1)-induced cell proliferation and collagen synthesis in cultured rat cardiac fibroblasts (CFs) and reduced left ventricle collagen deposition in rats with aldosterone (salt)- and ANG II-induced hypertension. However, it is not known whether these effects are mediated by receptor bindin...

Topographical evaluation of aphasic brain lesions can enhance our knowledge of cognitive physiology and plasticity. This prospective study was conducted on 100 stroke-afflicted patients with aphasia admitted in Valie-Asr Hospital (Khorasan, Iran) in 2003. Topography of infarct lesions was detected by a neurologist based on the map of brain vascular territories in CT-scan. Aphasic lesions catego...

Let R be a unit-regular ring, and let a, b, c ? satisfy aba = aca. If ac or ba is Drazin invertible, we prove that their inverses are similar. Furthermore, if group then similar to ba. For any n?n complex matrices A, B,C with ABA ACA, AC BA only k-powers have the same rank. These generalize known Flanders? theorem proved by Hartwig.

The distribution of selectively administered papaverine was determined in nine patients with delayed cerebral vasospasm in the territories of the anterior (ACA) and/or middle cerebral arteries (MCA) secondary to aneurysmal subarachnoid hemorrhage by simultaneous infusion with technetium-99m-hexamethyl-propyleneamine oxime (99mTc-HMPAO). Four of the nine patients had a ruptured anterior communic...

Purpose To evaluate the magnitudes and axis orientation of anterior corneal astigmatism (ACA) and posterior corneal astigmatism (PCA), the ratio of ACA to PCA, and the correlation between ACA and PCA in the different stages of keratoconus (KCN). Methods This retrospective case series comprised 161 eyes of 161 patients with KCN (104 men, 57 women; mean age, 22.35 ± 6.10 years). The participant...
