results 81 females aged 24 to 67 years (mean 43 ± 9.2) met the inclusion criteria and had adequate samples for histopathologic study. 28 (34%) patients had ml, 46 (56.8%) patients had nml and 7 (8.6%) had both ml and nml. rate of normal result, epithelial hyperplasia, fibrocystic changes, fibroadenoma, papilloma, atypical hyperplasia, mixed fibrocystic changes and atypical hyperplasia, ductal c...
Purpose: The purpose of this study is to evaluate the incidence and the degree of peritumoral edema on MRI in meningioma and to correlate other MR findings withtheedema. Materals and Methodds: MR images of 35 patients with histologically -confirmed meningioma were retrospectively reviewed. We analyzed the MR findings with special attention to the presence or absence and degree of edema. The ede...
OBJECTIVE To analyze the magnetic resonance (MR) imaging findings of invasive micropapillary carcinoma of the breast. MATERIALS AND METHODS MR images were retrospectively evaluated in 14 patients (age range: 37-67, mean age: 49 years) with pathologically confirmed invasive micropapillary carcinoma of the breast. The enhancement type (mass/non-mass), shape, margin, contrast enhancement, and ti...
Background: The aim of this study was to review and characterize the pattern of CNS lesions in patients suffering from AIDS and to correlate these patterns with clinical disorders. Method: The MR scan, medical records and laboratory findings of 58 AIDS patients were reviewed retrospectively during April 1994 to November 1997 at the Olive view/UCLA and Shiraz Medical Centers, and the patterns o...
the present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in iranian efl setting. sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on nelson language proficiency test. then, their grammar ability was measured based ...
We study the see-saw enhancement mechanism in presence of the right-handed phases of the Dirac neutrino mass matrix and the Majorana mass matrix. The enhancement condition given by S mirnov is modified. We point out that the see-saw enhancement could be obt ained due to the right-handed phases even if the Majorana matrix is proportional to the unit matrix. We show a realistic Dirac mass matrix ...
The ABC effect-a puzzling low-mass enhancement in the pipi invariant mass spectrum, first observed by Abashian, Booth, and Crowe-is well known from inclusive measurements of two-pion production in nuclear fusion reactions. Here we report on the first exclusive and kinematically complete measurements of the most basic double-pionic fusion reaction pn-->dpi;{0}pi;{0} at beam energies of 1.03 and ...
We report on an exclusive and kinematically complete high-statistics measurement of the basic double-pionic fusion reaction pn→dπ(0)π(0) over the full energy region of the ABC effect, a pronounced low-mass enhancement in the ππ-invariant mass spectrum. The measurements, which cover also the transition region to the conventional t-channel ΔΔ process, were performed with the upgraded WASA detecto...
In this talk, we firstly overview the experimental status of N̄X (1625), which is an enhancement structure observed in KΛ̄ invariant mass spectrum of J/ψ→ pKΛ̄ process. Then we present the result of the decay of N̄X(1625) under the two molecular assumptions, i.e. S-wave Λ̄K − and S-wave Σ̄K molecular states. Several experimental suggestions for N̄X (1625) are proposed.
