A DC power system receives AC electrical power and DC electrical power from separate first and second sources simultaneously. The DC power system delivers DC electrical power to an output for use by a load requiring DC power. The DC power system includes a converter to convert AC electrical power to DC electrical power and a power sharing control device to control and distribute the DC electrical power to an output. The first source of DC electrical power includes a storage battery, which provides standby DC electrical power to the DC power system. It also includes a power sharing device, which maintains the storage battery fully charged for use at peak loads, when the DC output electrical power is insufficient to meet the DC load. The second source of DC electrical power is a cogenerator such as a fuel cell, a thermo photovoltaic generator or an internal combustion engine and an alternator for generating and delivering DC electrical power to the power sharing device, while producing and delivering

Gliomas exhibiting oligodendroglial features consist of oligodendrogliomas (WHO quality II) and anaplastic oligodendrogliomas (WHO quality III) aswell as oligoastrocytomas (WHO quality II), anaplastic oligoastrocytomas (WHO quality III) and glioblastomas with an oligodendroglial component (GBMO, WHO quality IV) [1]. Oligodendroglial tumors take into account 15-20% of most gliomas [2,3]. The recognition from the genes targeted by full 1p/19q co-deletion, a quality of oligodendrogliomas, is a long-standing Tariquidar search. Combined lack of entire chromosome hands 1p and 19q may be the most frequently recognized hereditary imbalance in oligodendroglial tumors, happening in 60-90% of oligodendrogliomas and 30-50% of oligoastrocytomas while they may be rarely within GBMO [4-6]. The ...

N2 - The chromosome (chr) 1p deletion is a favorable biomarker in oligodendroglial tumors and is even more powerful a marker when combined with chr 19q loss. As a result, the 1p deletion is taken into account more and more in clinical trials and the management of patients. However, the laboratory technique implemented for detection of this biomarker has been a topic of debate. To illustrate the usefulness of evaluating multiple loci, we here report two anaplastic oligodendrogliomas that were investigated using fluorescent in situ hybridization (FISH) and bacterial artificial chromosome (BAC)-array-based comparative ...

The ZytoDot ® 2C SPEC 1p36/1q25 Probe is designed for the detection of 1p deletions by Chromogenic in situ Hybridization (CISH). Deletions affecting the short arm of chromosome 1 (1p) are frequently found in human gliomas and neuroblastomas, but also in breast, lung, endometrial, ovarian, and colorectal carcinomas. Loss of 1p is a strong prognostic factor in patients with neuroblastoma. Since loss of 1p reliably identifies patients at high risk in stages I, II, and IVS, which are otherwise clinically favorable, more aggressive therapy may be considered in these patients. Several studies showed correlation of combined allelic losses at 1p36 and 19q13 with oligodendroglioma histology and association with both chemotherapeutic response and survival in patients with anaplastic oligodendrogliomas. Hence, determination of 1p and 19q status may aid therapeutic decisions and predict outcome in patients with anaplastic oligodendrogliomas.
Oligodendrogliomas are gliomas that arise in the cerebral hemispheres of young and middle-aged adults. The tumors have a propensity to arise in the gray matter or superficial white matter of the frontal lobes, but oligodendrogliomas may also arise in other regions of the central nervous system.
Mixed gliomas, such as oligoastrocytomas (OA), anaplastic oligoastrocytomas, and glioblastomas (GBMs) with an oligodendroglial component (GBMO) are defined as tumors composed of a mixture of two distinct neoplastic cell types, astrocytic and oligodendroglial. Recently, mutations ATRX and TP53, and codeletion of 1p/19q are shown to be genetic hallmarks of astrocytic and oligodendroglial tumors, respectively. Subsequent molecular analyses of mixed gliomas preferred the reclassification to either oligodendroglioma or astrocytoma. This study was designed to apply genetically integrated diagnostic criteria to mixed gliomas and determine usefulness and prognostic value of new classification in Korean patients ...
Clinical management of grade III oligodendroglioma G Simonetti, P Gaviani, A Botturi, A Innocenti, E Lamperti, A Silvani Neurooncology Unit, Fondazione IRCCS Istituto Neurologico Carlo Besta, Milan, Italy Abstract: Oligodendrogliomas represent the third most common type of glioma, comprising 4%–15% of all gliomas and can be classified by degree of malignancy into grade II and grade III, according to WHO classification. Only 30% of oligodendroglial tumors have anaplastic characteristics. Anaplastic oligodendroglioma (AO) is often localized as a single lesion in the white matter and in the cortex, rarely in brainstem or spinal cord. The management of AO is deeply changed in the recent years. Maximal safe surgical resection followed by radiotherapy (RT) was considered as the standard of care since paramount findings regarding molecular aspects, in particular co-deletion of the short arm of chromosome 1 and the long arm of chromosome 19, revealed that these subsets of AO, benefit in terms of overall
Loss of heterozygosity (LOH) of the short arm of chromosome 1 (1p) and the long arm of chromosome 19 (19q) is an early event in oligodendroglioma that occurs in up to 80% of patients and is associated with therapeutic sensitivity and longer overall survival. The purpose of this study was to confirm the reported association in patients at this centre, then identify and characterise genes that were differentially expressed and may function as a tumour suppressor or contribute to therapeutic sensitivity in oligodendroglioma. A clinical review of oligodendroglioma patients treated at Royal North Shore and North Shore Private Hospitals between 1990 and 2009 confirmed the association between LOH 1p/19q and longer overall survival in WHO grade III oligodendroglioma patients. Younger age and lower tumour grade were additionally confirmed as positive prognostic factors. Exon microarrays were used to identify changes in gene expression between oligodendrogliomas with and without LOH 1p/19q. Seventeen ...

Oligodendroglioma is characterized by unique clinical, pathological, and genetic features. Recurrent losses of chromosomes 1p and 19q are strongly associated with this brain cancer but knowledge of the identity and function of the genes affected by these alterations is limited. We performed exome sequencing on a discovery set of 16 oligodendrogliomas with 1p/19q co-deletion to identify new molecular features at base-pair resolution. As anticipated, there was a high rate of IDH mutations: all cases had mutations in either IDH1 (14/16) or IDH2 (2/16). In addition, we discovered somatic mutations and insertions/deletions in the CIC gene on chromosome 19q13.2 in 13/16 tumours. These discovery set mutations were validated by deep sequencing of 13 additional tumours, which revealed seven others with CIC mutations, thus bringing the overall mutation rate in oligodendrogliomas in this study to 20/29 (69%). In contrast, deep sequencing of astrocytomas and oligoastrocytomas without 1p/19q loss revealed ...
OPINION STATEMENT: Anaplastic oligodendroglial tumors have gained increasing interest with the emerging role of molecular markers and systemic chemotherapy during the past years. The long-term results of two landmark trials, RTOG 9402 and EORTC 26961, have resulted in a reconsideration of the appropriate therapeutic approaches for patients with these tumors. Both trials indicate that patients whose tumors harbor a 1p/19q co-deletion benefit particularly from the addition of procarbazine/lomustine (CCNU)/vincristine (PCV) chemotherapy to radiation therapy (RT). The median survival of patients with co-deleted tumors treated within the RTOG trial with PCV before irradiation was 14.7 years compared with 7.3 years of patients who received RT alone. Median overall survival has not been reached in the RT plus PCV arm of the EORTC trial, but a similar difference can be anticipated after a follow-up of more than 12 years. In contrast, no such benefit was observed for patients with tumors lacking 1p/19q ...
These two tumour types comprise approximately one quarter of all gliomas with astrocytomas taking up the other three quarters.. What is the prognosis of patients with oligodendrogliomas? Oligodendrogliomas tend to be diagnosed more often than ependemyomas. The prognosis of patients with oliogodendrogliomas is better overall than that of patients with astrocytomas, however it worsens if the tumour progresses to the anaplastic stage. The evolution of oligodendrogliomas is similar to that of astrocytomas. If the tumour is caught in time, and treated, via means of surgery, the patient may be able to live up to ten years, and have a median survival rate of 5 years.. What do oligodendrogliomas appear like on the macroscopic and microscopic level? ...

The number of clinical, histopathologic, and molecular prognostic markers to estimate the outcome of patients with various types of gliomas, including low-grade gliomas, is steadily increasing (2, 32). In contrast, few studies have tried to distinguish markers that characterize the natural course of disease from markers that predict PFS and OS in response to specific therapeutic measures. The observation until first PD of surgically treated patients followed without adjuvant radiotherapy, or chemotherapy is the only way to determine whether a marker predicts outcome in the absence of adjuvant DNA-damaging treatment and is thus a prognostic marker independent of radiotherapy and chemotherapy. For instance, 1p/19q deletion is strongly predictive for prolonged PFS and OS in patients with anaplastic oligodendroglial tumors (WHO grade III) who are treated with radiotherapy or radiotherapy plus nitrosourea-based chemotherapy or temozolomide alone (14, 33, 34). Yet, 1p/19q deletion did not predict PFS ...

Anaplastic oligodendroglial tumors are rare neoplasms with no standard approach to treatment. We sought to determine patterns of treatment delivered over time and identify clinical correlates of specific strategies using an international retrospective cohort of 1013 patients diagnosed from 19812007. Prior to 1990, most patients received radiotherapy (RT) alone as initial postoperative treatment. After 1990, approximately 50 of patients received both RT and chemotherapy (CT) sequentially and/or concurrently. Treatment with RT alone became significantly less common (67 in 19801984 vs 5 in 20052007, P | .0001). CT alone was more frequently administered in later years (0 in 19801984 vs 38 in 20052007; P | .0001), especially in patients with 1p19q codeleted tumors (57 of codeleted vs 4 with no deletion in 20052007; P | .0001). Temozolomide replaced the combination of procarbazine, lomustine, and vincristine (PCV) among patients who received CT alone or with RT (87 vs 2 in 20052007). In the most recent time

This is my first post as well so I will give you a little background first. I was diagnosed in September of 2003 with a grade II mixed Oligodendroglioma. I was given the option of doing nothing and taking a wait and see approach or being more aggressive and attempting to remove as much as possible with surgery. I chose the surgery option and they were able to remove about 2/3 of the tumor from my left frontal lobe. While I was on the table the surgeon spoke to my family and told them he could try to get the rest but he would have to remove so much good brain tissue that damage was likely and there was a large risk of me coming out of the surgery a different person. Fortunately my family made the right decision and decided against any further removal. I started Temodar in December of 2003 and continued that until February of 2006 with a lapse due to the onset of some severe side effects that required stopping treatment for about 4-5 months. My doctors were going to do radiation therapy but at the ...

Arm II: Patients undergo radiotherapy as in arm I, then begin ...
Pathological differentiation of oligodendroglioma and mixed oligoastrocytoma from astrocytoma is difficult, relying on morphological characteristics due to the lack of reliable immunohistochemical stains. Oligodendrocytes, the presumed cell of origin of oligodendrogliomas, highly express the genes encoding myelin basic protein (MBP) and proteolipid protein (PLP). We analyzed the expression of these genes to determine whether they might be useful molecular markers of oligodendrocytic tumors. MBP and PLP were highly expressed in all oligodendrogliomas and minimally expressed in glioblastomas multiforme. MBP was highly expressed in mixed oligoastrocytomas, whereas PLP expression was minimal. The association between tumor classification and expression of the MBP and PLP genes was statistically significant. Expression of these genes may serve as a useful molecular marker for some subtypes of human gliomas. ...
Differentiating low-grade astrocytomas from low-grade oligodendrogliomas preoperatively with use of imaging is important for several reasons. First, these two tumor types are well-defined, clinicopathologic entities with distinct biologic and prognostic characteristics for which distinction based on histopathologic evaluation, the current reference standard, can be difficult and not without error (2, 3, 11). The histopathologic evaluation of low-grade glioma is challenged by a mixed cellular component in a given tumor that can lead to subjective criteria for determining the cell of origin, inherent sampling error associated with a surgical tissue specimen, and lack of specific tumor markers. Preoperative anatomic imaging already plays a complementary role by providing information on tumor location, surgical resectablity, satellite focus of tumor, and reactive changes in the adjacent brain-all of which are important factors influencing treatment and outcome, but which cannot be assessed directly ...

Oligodendrogliomas are the second most common malignant brain tumor in adults and exhibit characteristic losses of chromosomes 1p and 19q. To identify the molecular genetic basis for this alteration, we performed exomic sequencing of seven tumors. Among other changes, we found that the CIC gene (homolog of the Drosophila gene capicua) on chromosome 19q was somatically mutated in six cases and that the FUBP1 gene [encoding far-upstream element (FUSE) binding protein] on chromosome 1p was somatically mutated in two tumors. Examination of 27 additional oligodendrogliomas revealed 12 and 3 more tumors with mutations of CIC and FUBP1, respectively, 58% of which were predicted to result in truncations of the encoded proteins. These results suggest a critical role for these genes in the biology and pathology of oligodendrocytes ...

Oligodendrogliomas are a type of glioma that are believed to originate from the oligodendrocytes of the brain or from a glial precursor cell. They occur primarily in adults (9.4% of all primary brain and central nervous system tumors) but are also found in children (4% of all primary brain tumors). The average age at diagnosis is 35 years. In anywhere from fifty to eighty percent of cases, the first symptom of an oligodendroglioma is the onset of seizure activity. They occur mainly in the frontal lobe. Headaches combined with increased intracranial pressure are also a common symptom of oligodendroglioma. Depending on the location of the tumor, any neurological deficit can be induced, from visual loss, motor weakness and cognitive decline. A computed tomography (CT) or magnetic resonance imaging (MRI) scan is necessary to characterize the anatomy of this tumor (size, location, heter/homogeneity). However, final diagnosis of this tumor, like most tumors, relies on histopathologic examination ...
Peutz-Jeghers syndrome is caused by mutations in a gene on chromosome 19 known as STK11. Genetic testing is available clinically. Mutations in STK11 are identified in nearly all individuals with a positive family history and about 90 percent of individuals with no previous family history. Almost all people with PJS will be diagnosed with one or more of the associated cancers during their lifetime.. The STK11 gene is a tumor suppressor gene, which usually controls cell growth and cell death. Both copies of a tumor suppressor gene must be altered, or mutated, before a person will develop cancer. With PJS, the first mutation is inherited from either the mother or the father and is present from birth in all cells of the body. This is called a germline mutation. Whether a person who has a germline mutation will develop cancer and where the cancer(s) will develop depends on where (which cell type) the second mutation occurs. For example, if the second mutation is in the breast, then breast cancer may ...

Ten patients (3 men, 7 women; age range 24-64 years [median 39 years]) with the following tumors were enrolled: glioblastoma (6), anaplastic astrocytoma (2), anaplastic oligoastrocytoma (1), and anaplastic oligodendroglioma (1). Modified WT1 peptide-pulsed DC vaccine was administered to 7 patients, tumor lysate-pulsed DC vaccine to 2 patients, and both tumor lysate-pulsed and WT1-pulsed DC vaccine to 1 patient. The clinical response was stable disease in 5 patients with WT1-pulsed DC vaccination. In 2 of 5 patients with stable disease, neurological findings improved, and MR images showed tumor shrinkage. No serious adverse events occurred except Grade 1-2 erythema at the injection sites. WT1 tetramer analysis detected WT1-reactive cytotoxic T cells after vaccination in patients treated with WT1-pulsed therapy. Positivity for skin reaction at the injection sites was 80% (8 of 10 patients) after the first session, and positivity remained for these 8 patients after the final session. ...
