BACKGROUND AND PURPOSE On diffusion-weighted imaging (DWI), metastatic tumors of the brain may exhibit different signal intensities (SI) depending on their histology and cellularity. The purpose of our study was to verify the hypotheses (1) that SI on DWI predict the histology of metastases and (2) that apparent diffusion coefficient (ADC) values reflect tumor cellularity. MATERIALS AND METHO...
Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. This study evaluates the cytomorphologic features of endometriosis in various cytologic specimen types [fine-needle aspiration (FNA), effusion cytology (EF), touch imprint (ToP), and cervical smear (PAP)], and assesses the key elements helpful in recognizing this lesion. A total of 18 cases (8 FNA, 4 EF, ...
OBJECTIVES Recently, Atuegwu et al. proposed a mathematical model based on ADCmean and ADCmin to calculation of cellularity. Our purpose was to compare the calculated cellularity according to the formula with the estimated cell count by histopathology in different tumors. METHODS For this study, we re-analyzed our previous data regarding associations between ADC parameters and histopathologic...
هدف از این تحقیق بررسی امکان تولید سلولهای زایا (gcs) از سلولهای بنیادی مزانشیمی مغز استخوان (bm-mscs) در محیط آزمایشگاه بوده است. در این مطالعه سعی شده است تا به کمک برخی مکمل ها bm-mscهای قوچ را به gcهای نر تمایز داد. مکمل ها بر اساس اطلاعات موجود در منابع دربار? نقش آنها در تمایز سلولهای زایا (gcs) در بدن پستانداران، انتخاب شدند. ابتدا bm-mscها از نمون? مغز استخوان قوچ جدا شده و پس از تائید ...
To investigate whether alterations in the cellular component of the trabecular meshwork occur with age, we evaluated trabecular meshwork cellularity and absolute cell number, using specimens obtained from patients ranging in age from newborn to 81 years. We obtained reproducible, quantitative measurements of these parameters, using montages of 1 micrometer meridional sections. A progressive dec...
We are grateful to Peter Thompson for pointing out an error in [1, Lemma 3.5, p. 1848]. The original proof worked only under the assumption that θ ̂ $\hat{\theta }$ is a vector of constants. However, some components $\hat{\bm{\theta }}$ could be states dynamic consideration, and lemma was used such setup (i.e., with involving states) later Proposition 3.4]. give more explicit version statement p...
BACKGROUND To assess gliomas using image-based estimation of cellularity, we utilized isotropic diffusion spectrum imaging (IDSI) on clinically feasible diffusion tensor imaging (DTI) and compared it with amino acid uptake measured by α[(11)C]methyl-L-tryptophan positron emission tomography (AMT-PET). METHODS In 10 patients with a newly-diagnosed glioma, metabolically active tumor regions wer...
In the first part, we prove that the number of (1, β)-BM relations is 3 ·5 · . . . · (2β+1), which was conjectured by Jason Kimberley. In the second part, we construct two isomorphisms between certain (2, 2)-BM groups. This completes the classification of (2, 2)-BM groups initiated in [4].
