PURPOSE To evaluate the relationship between the primary breast volume and dose received by the ipsilateral lung, heart (for left-breast cancers), and contralateral breast during primary breast irradiation using intensity-modulated radiation therapy (IMRT). METHODS AND MATERIALS Sixty-five patients with breast carcinoma were treated using 6-MV photons with IMRT technique using the Eclipse Pla...

Objective: The main objective of this study was to analyze the differences in ipsilateral and contralateral internal mammary artery (IMA) and lateral thoracic artery (LTA) width in patients with malignant and benign breast tumor. Materials and Methods: A total of 104 female patients, of which 41 had benign and 63 had malignant tumors, were included in the study. The diameters of the IMA and LTA...

The neural organization of the pathways from the superior colliculus (SC) to trochlear motoneurons was analyzed in anesthetized cats using intracellular recording and transneuronal labeling techniques. Stimulation of the ipsilateral or contralateral SC evoked excitation and inhibition in trochlear motoneurons with latencies of 1.1-2.3 and 1.1-3.8 ms, respectively, suggesting that the earliest c...

Alzheimer's disease (AD) and cerebral ischaemia share similar features in terms of altered amyloid precursor protein (APP) processing and β-amyloid (Aβ) accumulation. We have previously shown that Aβ and calcium deposition, and β-secretase activity, are robustly increased in the ipsilateral thalamus after transient middle cerebral artery occlusion (MCAO) in rats. Here, we investigated whether t...

BACKGROUND AND PURPOSE The purpose of the present study was to assess whether the direction of flow via the circle of Willis (CoW) changed after stenting for severe internal carotid artery (ICA) stenosis. METHODS 65 patients (38 men, mean age 63.2 +/- 8.4 years, range 44-82) with a symptomatic ICA occlusion were investigated. Magnetic resonance angiography was performed prior to and 1 week af...

Motor evoked responses to focal transcranial magnetic stimulation were investigated over the unaffected hemisphere in 15 patients with hemiparesis after ischaemic stroke and compared with data from normal control subjects. Whereas responses to muscles ipsilateral to the stimulated hemisphere could only be elicited at maximal intensities in two out of 12 normal control subjects, such ipsilateral...

Transcutaneous electrical nerve stimulation (TENS) reduces pain through central mechanisms involving spinal cord and brainstem sites. Since TENS acts through central mechanisms, we hypothesized that TENS will reduce chronic bilateral hyperalgesia produced by unilateral inflammation when applied either ipsilateral or contralateral to the site of muscle inflammation. Sprague-Dawley rats were inje...

Movements of the upper limb are controlled mostly through the contralateral hemisphere. Although overall activity changes in the ipsilateral motor cortex have been reported, their functional significance remains unclear. Using human functional imaging, we analyzed neural finger representations by studying differences in fine-grained activation patterns for single isometric finger presses. We de...

BACKGROUND We conducted a dosimetric comparison of an ipsilateral beam arrangement for intensity modulated radiotherapy (IMRT) with off-axis beams. PATIENTS AND METHODS Six patients who received post-operative radiotherapy (RT) for parotid malignancies were used in this dosimetric study. Four treatment plans were created for each CT data set (24 plans): 1) ipsilateral 4-field off-axis IMRT (4...

Establishing a diagnosis of recurrent deep vein thrombosis (RDVT) by compression ultrasonography (CUS) is often difficult because persistent abnormal findings of the deep veins are common after a first episode of DVT. This may lead to a high percentage of potential misclassified patients with ipsilateral RDVT. The objective of the study is to evaluate the diagnostic management of ipsilateral RD...
