trolled neoplastic cell proliferation, solid tumor masses typically exhibit abnormal blood vessel networks that fail to provide adequate and homogeneous nutritional support to the tumor cells. Such spatial and temporal heterogeneity of the microcirculation within a tumor can result in an expansion of intercapillary space and a decrease in vessel density. These factors may consequently lead to i...

Intra-abdominal desmoid tumor is rare and seldom reported in the literature. It can grow large before causing symptoms, such as obstructing bowel loops or urinary system. Here, we present a 29-year-old male who suffered from intra-abdominal desmoid tumor, and describe its imaging findings on ultrasound and abdominal computed tomography. This tumor usually presents as a large homogeneous hypoden...

Leiomyosarcoma is an uncommon tumor that rarely metastasizes to the brain. It has been suggested that improved chemotherapy-resulting in improved survival rates-may have changed the metastatic pattern of this tumor, with an increasing frequency of cerebral metastasis. We present two histologically proven cases of leiomyosarcoma, one with a metastatic lesion in the cerebrum and the other in the ...

We report here a case of an inflammatory myofibroblastic tumor in the retroperitoneum, which mimicked a germ cell tumor of the undescended testis. A 75-year-old healthy man presented with a palpable abdominal mass. On the computed tomography image, there was large, well-defined soft tissue mass in the left side of the retroperitoneum, and there was no visible left testis or seminal vesicle. Aft...

Let be a locally compact non?abelian group and be a compact subgroup of also let be a ?invariant measure on the homogeneous space . In this article, we extend the linear operator as a bounded surjective linear operator for all ?spaces with . As an application of this extension, we show that each frame for determines a frame for and each frame for arises from a frame in via...

A 41-year-old woman was referred to our hospital because of a rectal tumor detected incidentally by colonoscopy at another hospital. Colonoscopy revealed a submucosal tumor with slightly erythematous surface in the rectum (Figure 1). Endoscopic ultrasonography (EUS) showed a homogeneous hypoechoic lesion measuring 14 mm in diameter with shadowing consistent with calcification. Continuity betwee...

OBJECTIVE To determine histopathologic findings related to the indeterminate or inadequate result of fine-needle aspiration biopsy (FNAB) in papillary thyroid carcinomas (PTCs) and to correlate histopathological findings with ultrasonographic features of tumors. MATERIALS AND METHODS We retrospectively reviewed the medical records of FNAB, histopathologic characteristics, and sonographic find...

let $g$ be a locally compact group, $h$ be a compact subgroup of $g$ and $varpi$ be a representation of the homogeneous space $g/h$ on a hilbert space $mathcal h$. for $psi in l^p(g/h), 1leq p leqinfty$, and an admissible wavelet $zeta$ for $varpi$, we define the localization operator $l_{psi,zeta} $ on $mathcal h$ and we show that it is a bounded operator. moreover, we prove that the localizat...

Introduction: In 3DCRT the number of therapeutic fields has dramatic impact on treatment results especially in stomach cancer. Traditionally, for radiotherapy of stomach cancer the therapeutic procedure was using two fields (AP- PA or AP Lateral with wedge) to achieve smooth and homogeneous dose distribution in tumor. But nowadays, adding lateral or oblique fields to aforement...

Egg lectin of Rana japonica, which specifically agglutinates transformed cells but does not agglutinate nontransformed cells and erythrocytes, has been isolated by gel filtration and successive ion-exchange chromatographies on diethylaminoethyl cellulose and carboxymethylcellulose columns and has been characterized as a homogeneous carbohydrate-free protein with a relative molecular weight of 1...
