Motivated by the GKM picture of the equivariant cohomol-ogy ring for a torus action on an orbifold we define one-skeletons and their corresponding rings, H(Γ, α). We prove that, under a mild gener-icity condition, such a ring is a free S(g *)−module, with generators given by Thom classes of flow-outs of the vertices. We also show that many interesting notions and results in symplectic geometry,...

Background: Ovarian cancer is the fifth most common cancer in woman and the fifth most frequent cause of cancer death. Ovarian cancers are usually asymptomatic until metastasized, patients have advanced disease at diagnosis in more than 2/3 of the cases. Totally 75-80 % of ovarian masses are benign. The strongest patient related risk factor for ovarian cancer is increasing age. The most ovarian...

Computed tomographic (CT) abnormalities in the brain were identified in 31 of 405 patients with leukemia or lymphoma. Abnormalities included neoplastic masses (15), hemorrhage (nine), abscess (two), other brain tumors (four), and methotrexate leukoencephalopathy (one). CT was normal in 374 patients including 148 with meningeal disease diagnosed by cerebrospinal fluid cytologic examination. Prio...

BACKGROUND AND PURPOSE Brain tumors affecting language-relevant areas may influence language lateralization. The purpose of this study was to systematically investigate language lateralization in brain tumor patients using clinical language fMRI, comparing the results with a group of healthy volunteers. MATERIALS AND METHODS Fifty-seven strictly right-handed patients with left-hemispheric-spa...

We report the findings from whole-brain proton MR spectroscopy, quantifying the neuronal marker N-acetylaspartate (NAA), for 2 presurgical meningioma patients and 10 healthy controls. The patients' whole-brain NAA (WBNAA) concentrations were considerably elevated (3+ SDs) compared with healthy controls when excluding the tumors from brain volume; WBNAA levels normalized following correction to ...

The present study included seroprevalence detection of Toxoplasma gondii in human and chickens (Gallus domesticus) AL-Door district, Salahdin province, the histological effects T. on some internal organs (brain, kidneys, liver muscles) from chickens. Positive result for toxoplasmosis was recorded 22.3% with highest prevalence positive IgG that reported 14.1%. Based gender, significant increasin...

Through the cou~esy of Dr. Montgomery I have been permitted to study sections from his tumor and to make (1) a note upon the nervous tissue present, and (2) some remarks concerning the theories which have been advanced to explain teratomala in general. I. The tumor contains large masses of nervous "tissue distributed throughout its substance. While most of this nerve tissue resembles embryonic ...

Allochthonous masses are common structures in Zagros fold-thrust belt. They are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. However, large allochthonous masses mapped in Dowgonbadan area in Dezful Embayment near the Mountain Front Fault (MFF) of Zagros show characteristics different from the belt common collapse stru...
