Accurate determination of HER2/neu status in breast carcinoma is essential. Alteration of preanalytic variables is known to affect HER2/neu results. American Society of Clinical Oncology (ASCO) and the College of American Pathologists (CAP) issued guidelines to standardize fixation for increased HER2/neu accuracy. We studied the effects of changing preanalytic variables on HER2/neu immunohistoc...
هدف تحقیق موردنظر بررسی ارتباط بین دانش لغوی زبان آموزان و استفاده آنها از راهبردهای یادگیری لغت می باشد. این تحقیق اساساً در نظر دارد علاوه بر راهبردهای یادگیری اثرگذار بر دامنه لغات، راهبردهای موثر در فهم لغات را هم شناسایی نماید. به عبارت دیگر هدف از این پژوهش پیدا کردن راهبردهای یادگیری لغاتی است که بهترین پیش بینی را بر دامنه ی لغات و فهم آن می کنند. راهبردهای یادگیری لغت به کار گرفته شده د...
We report a 69-year-old female patient with mucinous cystadenocarcinoma of the appendix and elevated serum carcinoembryonic antigen (CEA). Serum CEA levels were 27.6-37.8 ng/ml. An oval shaped cystic mass at the ileocecal region was consistently seen by several radiologic procedures such as, barium enema, ultrasonography, computed tomography, and magnetic resonance imaging. The tumor was resect...
background in surgical pathology, atypical small acinar proliferation is commonly detected in prostate biopsies. most studies on atypical small acinar proliferation have examined morphological characteristics and the utility of immunohistochemical studies.however, these resources are not available to many pathology departments. we have found that examining additional sections is a simple and in...
a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
Background and Aim: Growth of breast cancer cells is often affected by the female sex steroids. Determination of the cellular concentrations of estrogen (ER) and progesterone (PR) receptors in the tumor is continuously used to predict which patients may benefit from antihormonal therapy. The rate of hormone receptor positivity is related to differentiation and type of tumor tissues, age and men...
a simple, sensitive and selective method for solvent extraction and spectrophotemetric determination of lanthanum (ii) europium (iii), and cerium (iii) is described , the rare earth metals are extracted into chloroform solution of n-phenylbenzohydroxamic acid (pbha) at ph 9-10 various parameters are studied to optimize the extraction conditions. the molar absorptivity is found to increase from ...
