    The municipality of Monte Alegre, located in the Amazonian State of Para, Brazil, presents scattered areas with increased levels of natural radiation due to uranium rocks. The objectives of this dissertation were: to evaluate the mortality trend among Monte Alegre residents, and to compare it with that observed in neighbor municipalities (Alenquer and Prainha) without natural radiation sources; and to determine the impact of cancer distribution either in Monte Alegre or control counties population, taking into account their estimates of cancer incidence and mortality. The dissertation was organized in two papers. The first one aimed to evaluate the mortality trend for all causes of death, cancer, and unknown causes of death occurred between 1981-2005. Analyzed data was provided by the Brazilian National Mortality Information System (SIM), being the general population of the State of Para used as reference. In the second paper, cancer mortality risks at selected sites were ascertained using standardized mortality ratios (SMR) and mortality odds ratios (MOR). Additionally, cancer mortality risk ratios of Monte Alegre and control counties were obtained towards the ratio between SMRs of selected cancer sites in both areas. Three different sources of data were used to retrieve all cancer cases in the studied area, and therefore, to estimate cancer incidence in the studied populations: the diagnosed cancer cases at the regional reference centers for oncological care settled in Santarem, Belem and Manaus; the cancer-related hospitalization authorization records obtained at the Brazilian National Health System (SUS) registries; and primary data of cancer reported by local residents at a population-based health survey conducted by our research team in 2007-2008. A declining trend for all causes of death mortality in Monte Alegre general population, as well as for the unknown causes of death, was observed along the studied time series for both gender.

    Background NaV1.5 voltage-gated sodium channels are abnormally expressed in breast tumours and their expression level is associated with metastatic occurrence and patients’ death. In breast cancer cells, NaV1.5 activity promotes the proteolytic degradation of the extracellular matrix and enhances cell invasiveness. Findings In this study, we showed that the extinction of NaV1.5 expression in human breast cancer cells almost completely abrogated lung colonisation in immunodepressed mice (NMRI ...

  5. Imaging of tumor viability in lung cancer. Initial results using 23Na-MRI

    International Nuclear Information System (INIS)

    23Na-MRI has been proposed as a potential imaging biomarker for the assessment of tumor viability and the evaluation of therapy response but has not yet been evaluated in patients with lung cancer. We aimed to assess the feasibility of 23Na-MRI in patients with lung cancer. Three patients with stage IV adenocarcinoma of the lung were examined on a clinical 3 Tesla MRI system (Magnetom TimTrio, Siemens Healthcare, Erlangen, Germany). Feasibility of 23Na-MRI images was proven by comparison and fusion of 23Na-MRI with 1H-MR, CT and FDG-PET-CT images. 23Na signal intensities (SI) of tumor and cerebrospinal fluid (CSF) of the spinal canal were measured and the SI ratio in tumor and CSF was calculated. One chemonaive patient was examined before and after the initiation of combination therapy (Carboplatin, Gemcitabin, Cetuximab). All 23Na-MRI examinations were successfully completed and were of diagnostic quality. Fusion of 23Na-MRI images with 1H-MRI, CT and FDG-PET-CT was feasible in all patients and showed differences in solid and necrotic tumor areas. The mean tumor SI and the tumor/CSF SI ratio were 13.3 ± 1.8 x 103 and 0.83 ± 0.14, respectively. In necrotic tumors, as suggested by central non-FDG-avid areas, the mean tumor SI and the tumor/CSF ratio were 19.4 x 103 and 1.10, respectively. 23Na-MRI is feasible in patients with lung cancer and could provide valuable functional molecular information regarding tumor viability, and potentially treatment response.

  7. SG2NA enhances cancer cell survival by stabilizing DJ-1 and thus activating Akt

    International Nuclear Information System (INIS)

    SG2NA in association with striatin and zinedin forms a striatin family of WD-40 repeat proteins. This family of proteins functions as scaffold in different signal transduction pathways. They also act as a regulatory subunit of protein phosphatase 2A. We have shown that SG2NA which evolved first in the metazoan evolution among the striatin family members expresses different isoforms generated out of alternative splicing. We have also shown that SG2NA protects cells from oxidative stress by recruiting DJ-1 and Akt to mitochondria and membrane in the post-mitotic neuronal cells. DJ-1 is both cancer and Parkinson's disease related protein. In the present study we have shown that SG2NA protects DJ-1 from proteasomal degradation in cancer cells. Hence, downregulation of SG2NA reduces DJ-1/Akt colocalization in cancer cells resulting in the reduction of anchorage dependent and independent growth. Thus SG2NA enhances cancer cell survival. Reactive oxygen species enhances SG2NA, DJ-1 and Akt trimerization. Removal of the reactive oxygen species by N-acetyl-cysteine thus reduces cancer cell growth. - Highlights: • Reactive oxygen species (ROS) play potential role in cancer cell proliferation. • It enhances the association between DJ-1 and Akt mediated by SG2NA. • In cancer cells SG2NA stabilizes DJ-1 by inhibiting it from proteosomal degradation. • DJ-1 then activates Akt and cancer cells get their property of enhanced proliferation by sustained activation of Akt. • Further study on this field could lead to new target for cancer therapy

    A proportion of patients with hormone receptor-positive locally advanced or metastatic breast cancer will not have received prior endocrine therapy. However, there are limited clinical data specifically in these patients. We conducted a review of randomized phase II and III clinical studies of anastrozole, letrozole, exemestane, palbociclib, and fulvestrant to determine the evidence base supporting use of specific endocrine therapies in this patient population. From our findings, there is a paucity of clinical studies in patients with endocrine therapy-naïve disease; however, it appears that first-line treatment effects are consistent between patients who have and have not received prior endocrine treatment.

    In cholangiocarcinogenesis, chronic inflammation and oxidative stress play a key role. The Na(+)/H(+) exchanger (NHE) forms a potential link between control of intra- and pericellular pH and tumor development. Therefore, the effects of oxidant stress were determined by the use of tert-butyl hydroperoxide (t-BOOH) on Na(+)/H(+) exchange in a biliary epithelial cancer cell line (Mz-Cha-1). The cells were exposed to the hydroperoxide and the rate of recovery from acidosis was determined by the use of the pH-sensitive fluorochrome 2',7'-bis(carboxyethyl)-5(6)-carboxyfluorescein acetoxymethyl ester (BCECF/AM). t-BOOH reduced Na(+)/H(+) exchange activity in a dose-dependent manner. At 4 mM t-BOOH, Na(+)/H(+) exchange activity was virtually absent. This was accompanied by an increase in cytotoxicity (MTT assay). Glutathione repletion and intracellular Ca(++) chelation partially restored the Na(+)/H(+) exchange activity. Hydroperoxide seemed neither to alter the intracellular signal transduction pathways (cAMP and Ca(++) oscillations) nor the membrane distribution of the exchanger (immunostaining). Decrease in Na(+)/H(+) exchange activity in this model of oxidant stress may represent an early perturbation of membrane function, and the functional integrity of Na(+)/H(+) exchange could therefore be dependent on the glutathione redox system.

    2008-01-01

    Full Text Available Combinations of capecitabine and a taxane are highly active in metastatic breast cancer, and synergy between capecitabine and docetaxel has also been demonstrated. Such combinations potentially would provide a promising non–anthracycline-based alternative for patients with early breast cancer. Non-anthracycline preoperative regimens are a particularly interesting proposition in human epidermal growth factor receptor 2 (HER2-positive breast cancer, as they offer less cardiotoxicity and thus can be used concomitantly with preoperative trastuzumab therapy. Capecitabine plus docetaxel (XT and trastuzumab with XT (HXT are promising non-anthracycline regimens for the preoperative treatment of women with HER2-negative and HER2-positive breast cancer, respectively. The Xeloda in Neoadjuvant (XeNA trial, an open-label, multicenter, phase II study, independently assesses the efficacy of preoperative XT in HER2-negative and HXT in HER2-positive breast cancer. A particularly important feature of the XeNA study is the use of pathologic complete response (pCR plus near pCR (npCR as the primary endpoint. pCR is associated with long-term survival, and although it is valuable as a surrogate marker, pCR has some limitations. Measurement of residual breast cancer burden (RCB has been proposed as a more practical alternative to predict survival after preoperative chemotherapy. The combination of RCB-0 and RCB-I (npCR expands the subset of patients shown to benefit from preoperative chemotherapy, and achievement of pCR or npCR is associated with long disease-free survival. In XeNA, the sum of pCR and npCR will facilitate correlative studies designed to identify patients most likely to benefit from XT and HXT and may expedite the clinical evaluation of these novel preoperative regimens.

  16. Significance of the neurotensin receptor Na+/H+-exchanger 1 axis in human pancreatic cancer cells

    International Nuclear Information System (INIS)

    Pancreatic cancer is characterized by early dissemination and rapid acquisition of drug resistance, resulting in dismal prognosis in patients. New targeted therapies failed to improve the low five-year survival rates. Characterization of neuropeptides as growth factors for pancreatic cancer cells stimulated interest in the development of suitable inhibitors. In particular, neurotensin (NT) stimulated proliferation of cancer cell lines, and the NT receptor 1 (NTR1) antagonist SR48692 was found to inhibit growth of tumor xenografts. However, clinical application of SR48692 in small cell lung cancer failed to yield significant responses. Nevertheless, expression of NTRs in more than 90% of pancreatic tumors points to an important role of the NT - NTR system in this tumor entity. Therefore, the present study aimed at investigation of the significance of NT - NTR signaling by use of BxPC-3, PANC-1 and MIA PaCa-2 pancreatic cancer cells and the NTR-positive HT-29 colon carcinoma cell line for comparison. Functional NTR1 that triggers release of intracellular Ca2+ upon binding of the stable NT analog Lys8-Ψ-Lys9NT(8-13) was confirmed in all pancreatic cancer cell lines. The fraction of cells in S phase was increased in response to the NT analog and proliferation of the pancreatic cancer cells stimulated to a limited extent. In contrast to epidermal growth factor receptor (EGFR), NTR1 expression was found to reach a maximum in confluent cultures of resting (G1/0 phase) BxPC-3 and PANC-1 cells. In addition, again unlike EGFR, expression of NTR1 proved to be dependent on extracellular pH with highest levels under acidic conditions. Accordingly, Lys8-Ψ-Lys9NT(8-13) induced marked intracellular alkalinization in BxPC-3, PANC-1 and a panel of colon cancer cell lines and slight acidification in MIA PaCa-2 cells under conditions that confine regulation of intracellular pH to the ubiquitously expressed Na+/H+ exchanger 1 (NHE1). Similar results were obtained in bicarbonate

    Objectives Maintenance therapy is a standard therapeutic strategy in non-squamous non-small-cell lung cancer. However, there is no consensus regarding the benefit of maintenance therapy for patients with squamous cell lung cancer. We assessed maintenance therapy with S-1, an oral fluoropyrimidine agent, following induction therapy with carboplatin and S-1 in patients with squamous cell lung cancer. Methods In this phase II trial, chemotherapy-naïve patients with squamous cell lung cancer were enrolled to induction therapy with four cycles of carboplatin (at an area under the curve of 5 on day 1) and S-1 (80 mg/m(2)/day on days 1-14) in a 28-day cycle. Patients who achieved disease control after induction therapy received maintenance therapy with S-1 in a 21-day cycle until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival after administration of maintenance therapy. Results Fifty-one patients were enrolled in the study. The median progression-free survival from the start of maintenance therapy was 3.0 months (95 % confidence interval, 2.5-3.5). The most common toxicities associated with maintenance therapy were anemia, thrombocytopenia, and fatigue, but they were not severe. Conclusion S-1 maintenance therapy might be a feasible treatment option in patients with squamous cell lung cancer. PMID:27279143

    Full Text Available The aim of present study was to develop a model for a functional analysis of a recently identified marker of the ovarian cancer – sodium-dependent phosphate transporter NaPi2b. For this purpose, we have created HEK293 stable cell lines expressing wild type or mutant forms of NaPi2b (T330V substitution in a large extracellular loop and a 6 amino acid residues deletion in the C-terminal cytoplasmic tail, revealed in the ovarian cancer cell lines. The expression of wild type and mutant forms NaPi2b in the stable cell lines created was confirmed by Western-blot analysis with monoclonal antibodies against NaPi2b. The cellular models described here will be useful for studying the function of sodium-dependent phosphate transporter NaPi2b in health and disease.

    Combined radiochemotherapy (RCT) for gastric cancer with three-dimensional conformal radiotherapy (3D-CRT) results in ablative doses to the upper left kidney, while image-guided intensity-modulated radiotherapy (IG-IMRT) allows kidney sparing despite improved target coverage. Renal function in long-term gastric cancer survivors was evaluated with 3T functional magnetic resonance imaging (MRI) including diffusion-weighted imaging (DWI) and {sup 23}Na imaging. Five healthy volunteers and 13 patients after radiotherapy were included: 11 x IG-IMRT; 1 x 3D-CRT; 1 x ''positive control'' with stereotactic body radiotherapy (SBRT) of a metastasis between the spleen/left kidney. Radiation doses were documented for the upper/middle/lower kidney subvolumes. Late toxicity was evaluated based on CTC criteria, questionnaire, and creatinine values. Morphological sequences, DWI images, and {sup 23}Na images were acquired using a {sup 1}H/{sup 23}Na-tuned body-coil before/after intravenous water load (WL). Statistics for [{sup 23}Na] (concentration) and apparent diffusion coefficient (ADC) values were calculated for upper/middle/lower renal subvolumes. Corticomedullary [{sup 23}Na] gradients and [{sup 23}Na] differences after WL were determined. No major morphological alteration was detected in any patient. Minor scars were observed in the cranial subvolume of the left kidney of the 3D-CRT and the whole kidney of the control SBRT patient. All participants presented a corticomedullary [{sup 23}Na] gradient. After WL, a significant physiological [{sup 23}Na] gradient decrease (p < 0.001) was observed in all HV and IG-IMRT patients. In the cranial left kidney of the 3D-CRT patient and the positive control SBRT patient, the decrease was nonsignificant (p = 0.01, p = 0.02). ADC values were altered nonsignificantly in all renal subvolumes (all participants). Renal subvolumes with doses ≥ 35 Gy showed a reduced change of the [{sup 23}Na] gradient after WL (p = 0

    Although the Internet may help to increase cancer patients' awareness of clinical trials, little is known about the accessibility and quality of online clinical trial information. We simulated the experience of a naïve cancer patient without clinical trial knowledge by searching three popular search engines for treatment information for breast, lung, and prostate cancer, and myelodysplastic syndromes (MDS). Two coders independently evaluated website content for accessibility and quality. We screened 120 websites and identified 40 unique sites for analysis. Overall, 85% [95% confidence interval (CI), 70%-94%] of sites mentioned clinical trials on the landing page and 68% (51%-81%) included links to specific trials. Overall readability was poor. Approximately half of websites (36%-68%) included information on the potential benefits and risks of clinical trials and 40% provided information about when the site had been updated (25%-57%). Among sites with links to specific clinical trials, only 44% (25%-65%) provided an interactive interface that would allow patients to customize search results; breast (100%) and prostate (50%) sites were more interactive than lung (25%) and MDS (14%; P = 0.007). Although cancer clinical trial information is widely available on the Internet, its quality is highly variable. Given the fact that many emerging cancer therapeutics are personalized based on disease or genomic characteristics, interactive web-based interfaces could serve as powerful vehicles to help patients locate appropriate clinical trials. Without enhanced efforts to ensure greater interactivity of cancer treatment websites, patient awareness of relevant clinical trials may remain low. PMID:26265204

    In order to assess the exposure of the Portuguese population to ionizing radiation due to medical examinations of diagnostic radiology and nuclear medicine, a working group, consisting of 40 institutions, public and private, was created to evaluation the coletive dose in the Portuguese population in 2010. This work was conducted in collaboration with the Dose Datamed European consortium, which aims to assess the exposure of the European population to ionizing radiation due to 20 diagnostic radiology examinations most frequent in Europe (the 'TOP 20') and nuclear medicine examinations. We obtained an average value of collective dose of Almost-Equal-To 1 mSv/caput, which puts Portugal in the category of countries medium to high exposure to Europe. We hope that this work can be a starting point to bridge the persistent lack of studies in the areas referred to in Portugal, and to enable the characterization periodic exposure of the Portuguese population to ionizing radiation in the context of medical applications.

    Full Text Available BACKGROUND: 5α-reductase 1 (5αR1 and 5α-reductase 2 (5αR2 convert testosterone into the more potent androgen dihydrotestosterone. 5αR2 is the main isoenzyme in normal prostate tissue; however, most prostate tumors have increased 5αR1 and decreased 5αR2 expression. Previously, finasteride (5αR2 inhibitor treatment begun 3 weeks post-tumor implantation had no effect on Dunning R3327-H rat prostate tumor growth. We believe the tumor compensated for finasteride treatment by increasing tumor 5αR1 expression or activity. We hypothesize that finasteride treatment would not significantly alter tumor growth even if begun before tumor implantation, whereas dutasteride (5αR1 and 5αR2 inhibitor treatment would decrease tumor growth regardless of whether treatment was initiated before or after tumor implantation. METHODOLOGY/PRINCIPAL FINDINGS: Sixty 8-week-old male nude mice were randomized to Control, Pre- and Post-Finasteride, and Pre- and Post-Dutasteride (83.3 mg drug/kg diet diet groups. Pre- and post-groups began their treatment diets 1-2 weeks prior to or 3 weeks after subcutaneous injection of 1×10⁵ WPE1-NA22 human prostate cancer cells, respectively. Tumors were allowed to grow for 22 weeks; tumor areas, body weights, and food intakes were measured weekly. At study's conclusion, prostate and seminal vesicle weights were significantly decreased in all treatment groups versus the control; dutasteride intake significantly decreased seminal vesicle weights compared to finasteride intake. No differences were measured in final tumor areas or tumor weights between groups, likely due to poor tumor growth. In follow-up studies, proliferation of WPE1-NA22 prostate cancer cells and parent line RWPE-1 prostate epithelial cells were unaltered by treatment with testosterone, dihydrotestosterone, or mibolerone, suggesting that these cell lines are not androgen-sensitive. CONCLUSION: The lack of response of WPE1-NA22 prostate cancer cells to androgen

    Functional expression of voltage-gated Na+ channels (VGSCs) has been demonstrated in multiple cancer cell types where channel activity induces invasive activity. The signaling mechanisms by which VGSCs promote oncogenesis remain poorly understood. We explored the signal transduction process critical to VGSC-mediated invasion on the basis of reports linking channel activity to gene expression changes in excitable cells. Coincidentally, many genes transcriptionally regulated by the SCN5A isoform in colon cancer have an over-representation of cis-acting sites for transcription factors phosphorylated by ERK1/2 MAPK. We hypothesized that VGSC activity promotes MAPK activation to induce transcriptional changes in invasion-related genes. Using pharmacological inhibitors/activators and siRNA-mediated gene knockdowns, we correlated channel activity with Rap1-dependent persistent MAPK activation in the SW620 human colon cancer cell line. We further demonstrated that VGSC activity induces downstream changes in invasion-related gene expression via a PKA/ERK/c-JUN/ELK-1/ETS-1 transcriptional pathway. This is the first study illustrating a molecular mechanism linking functional activity of VGSCs to transcriptional activation of invasion-related genes.

Foram analisados os dados das estatísticas de mortalidade do Ministério da Saúde e os disponíveis nos registros de câncer de base populacional existentes nos municípios em Belém, Fortaleza, Recife, Goiânia, São Paulo e Porto Alegre (Brasil. Em 1986 o câncer foi responsável por 15,5% dos óbitos em mulheres acima de quinze anos no Brasil. Os cânceres de mama e útero representaram quase um terço desses óbitos. A comparação internacional mostrou que os coeficientes de incidência de câncer de colo de útero em Recife e Belém foram os mais altos do mundo e os de mama em Fortaleza e São Paulo são próximos dos encontrados nas regiões de mais altas cifras como nos Estados Unidos e alguns países da Europa. São discutidos os principais fatores de risco para os cânceres mais prevalentes entre as mulheres brasileiras, guardando as diferenças culturais, sociais e geográficas, bem como os programas de controle existentes. Conclui-se que os programas, de "screening" e de diagnóstico precoce para o câncer de colo uterino tiveram coberturas muito baixas. Considerou-se que o estabelecimento de uma política assistêncial e de controle que inclua a prevenção e o diagnóstico precoce para os cânceres de colo uterino e de mama nos programas de assistência à mulher deveria ser uma das prioridades de saúde pública, no Brasil.This study seeks to show the importance of cancer as a cause of morbidity and mortality among Brazilian women.

    Imaging guided photothermal agents have attracted great attention for accurate diagnosis and treatment of tumors. Herein, multifunctional NaYF4:Yb/Er@polypyrrole (PPy) core-shell nanoplates are developed by combining a thermal decomposition reaction and a chemical oxidative polymerization reaction. Within such a composite nanomaterial, the core of the NaYF4:Yb/Er nanoplate can serve as an efficient nanoprobe for upconversion luminescence (UCL)/X-ray computed tomography (CT) dual-modal imaging, the shell of the PPy shows strong near infrared (NIR) region absorption and makes it effective in photothermal ablation of cancer cells and infrared thermal imaging in vivo. Thus, this platform can be simultaneously used for cancer diagnosis and photothermal therapy, and compensates for the deficiencies of individual imaging modalities and satisfies the higher requirements on the efficiency and accuracy for diagnosis and therapy of cancer. The results further provide some insight into the exploration of multifunctional nanocomposites in the photothermal theragnosis therapy of cancers.Imaging guided photothermal agents have attracted great attention for accurate diagnosis and treatment of tumors.

    Full Text Available O carcinoma de mama é a neoplasia maligna mais comum em mulheres. Estudos moleculares do carcinoma de mama, baseados na identificação do perfil de expressão gênica por meio do cDNA microarray, permitiram definir pelo menos cinco sub-grupos distintos: luminal A, luminal B, superexpressão do HER2, basal e normal breast-like. A técnica de tissue microarray (TMA, descrita pela primeira vez em 1998, permitiu estudar, em várias amostras de carcinoma, os perfis de expressão protéica de diferentes neoplasias. No carcinoma de mama, os TMAs têm sido utilizados para validar os achados dos estudos preliminares, identificando, desta forma, os novos subtipos fenotípicos do carcinoma de mama. Dentre os subtipos classicamente descritos, o grupo basal constitui um dos mais intrigantes subtipos tumorais e é freqüentemente associado com pior prognóstico e ausência de alvos terapêuticos definidos. A classificação histopatológica do carcinoma de mama tem pobre valor preditivo. Portanto, a associação entre o diagnóstico histológico com técnicas moleculares nos laboratórios de anatomia patológica, por meio do estudo imunoistoquímico, pode determinar o perfil molecular do carcinoma de mama, buscando melhorar a resposta terapêutica. Este estudo visou resumir os mais recentes conhecimentos em que se baseiam os novos conceitos da classificação do carcinoma de mama.Breast cancer is the principal cause of death from cancer in women.

    A homogeneous immunoassay for the sensitive and selective determination of trace amounts of α-fetoprotein (AFP, a cancer marker) by detection in the near-infrared (NIR) region based on luminescence energy transfer (LET) from NaYF4:Yb,Tm/NaGdF4 core-shell upconverting nanoparticles to gold nanorods (GNRs) is presented. The carboxyl-functionalized NaYF4:Yb,Tm/NaGdF4 core-shell upconverting nanoparticles (UCNPs) were excited by a 980 nm continuous wavelength laser, and its emission peak appeared at a near-infrared wavelength (∼804 nm). The carboxyl-functionalized upconverting nanoparticles were conjugated with the anti-AFP (Ab1) and acted as donor. GNRs with a high absorption band around 790 nm, which was overlapped the UCNPs emission, were synthesized and acted as the acceptor. The donor (negatively charged) interacted with the acceptor (positively charged) via electrostatic interactions to bring them into close proximity. LET could occur, producing a quenching phenomenon. When the AFP antigens were added into the system, the binding affinity between AFP and Ab1 was stronger than the electrostatic interactions, which released the energy acceptors from the energy donors, interrupting luminescence energy transfer, and therefore, the luminescence was recovered. On the basis of the restored luminescence, a turn-on optical immunosening system was developed. Under the optimal conditions, the linear range of detection was from 0.18 to 11.44 ng/mL for AFP (R = 0.99), with a detection limit as low as 0.16 ng/mL. The proposed method has also been used to monitor AFP in human serum samples. Therefore, further study based on the NaYF4:Yb,Tm/NaGdF4 core-shell nanoparticles-GNRs construction may open the way for a new class of NIR-LET biosensors with wide applications. PMID:25296290

    Abstract We compared the diagnostic accuracy of 18F-labeled sodium fluoride (18F-NaF) PET-CT with 99m-technetium methylene diphosphonate (99mTc-MDP) single photon emission computed tomography (SPECT) to detect bone metastases (BMs) in patients with preoperative lung cancer. Patients with lung cancer (n = 181) were examined with 18F-NaF PET-CT, and another 167 patients with lung cancer were examined with 99mTc-MDP SPECT. 18F-NaF PET-CT and 99mTc-MDP SPECT were evaluated by 2 experienced readers. Lesions were graded on a scale of 0 (degenerative lesion) to 4 (definite BM), and equivocal lesions were determined as indifferent (grade 3). Based on patient-based analysis, there were only 4 equivocal patients in 18F-NaF PET-CT detection. However, in 99mTc-MDP SPECT detection, there were 19 equivocal patients, which indicated a significant difference in terms of occurrence ratio (χ2 = 9.005, P = 0.03). Sensitivity and specificity of PET-CT was significantly better than that of SPECT when equivocal reading was categorized as malignant or benign (P < 0.05). Based on lesions-based analysis, SPECT produced 26 equivocal lesions of 333 lesions, but PET-CT produced only 5 equivocal lesions of 991 lesions. PET-CT was significantly better than SPECT in the aspect of producing equivocal patients (χ2 = 58.141, P < 0.001). Sensitivity and specificity of PET-CT was significantly better than that of SPECT when equivocal reading was categorized as malignant or benign (P < 0.05). 18F-NaF PET-CT is a highly sensitive and specific modality for the detection of BM in patients with preoperative lung cancer. It is better than conventional 99mTc-MDP SPECT in detecting BM in patients with preoperative lung cancer. PMID:27100456

    Voltage-gated Na(+) channels (VGSCs) are heteromeric membrane protein complexes containing pore-forming α subunits and smaller, non-pore-forming β subunits. VGSCs are classically expressed in excitable cells, including neurons and muscle cells, where they mediate action potential firing, neurite outgrowth, pathfinding, and migration. VGSCs are also expressed in metastatic cells from a number of cancers. The Na(v)1.5 α subunit (encoded by SCN5A) is expressed in breast cancer (BCa) cell lines, where it enhances migration and invasion. We studied the expression of SCN5A in BCa array data, and tested the effect of the VGSC-blocking anticonvulsant phenytoin (5,5-diphenylhydantoin) on Na(+) current, migration, and invasion in BCa cells. SCN5A was up-regulated in BCa samples in several datasets, and was more highly expressed in samples from patients who had a recurrence, metastasis, or died within 5 years. SCN5A was also overexpressed as an outlier in a subset of samples, and associated with increased odds of developing metastasis. Phenytoin inhibited transient and persistent Na(+) current recorded from strongly metastatic MDA-MB-231 cells, and this effect was more potent at depolarized holding voltages. It may thus be an effective VGSC-blocking drug in cancer cells, which typically have depolarized membrane potentials. At a concentration within the therapeutic range used to treat epilepsy, phenytoin significantly inhibited the migration and invasion of MDA-MB-231 cells, but had no effect on weakly metastatic MCF-7 cells, which do not express Na(+) currents. We conclude that phenytoin suppresses Na(+) current in VGSC-expressing metastatic BCa cells, thus inhibiting VGSC-dependent migration and invasion. Together, our data support the hypothesis that SCN5A is up-regulated in BCa, favoring an invasive/metastatic phenotype. We therefore propose that repurposing existing VGSC-blocking therapeutic drugs should be further investigated as a potential new strategy to improve

    AIM: To investigate the roles of Bax and p53 proteins in photosensitivity of human colon cancer cells by using lysosome-localizing photosensitizer, ATX-S10Na (Ⅱ).METHODS: HCT116 human colon cancer cells and Bax-null or p53-null isogenic derivatives were irradiated with a diode laser. Early apoptosis and cell death in response to photodynamic therapy were determined by MTT assays, annexin V assays, transmission electron microscopy assays, caspase assays and western blotting.RESULTS: Induction of early apoptosis and cell death was Bax- and p53-dependent. Bax and p53 were required for caspase-dependent apoptosis. The levels of anti-apoptotic Bcl-2 family proteins, Bcl-2 and Bcl-XL,were decreased in Bax- and p53-independent manner.CONCLUSION: Our results indicate that early apoptosis and cell death of human colon cancer cells induced by photodynamic therapy with lysosome-localizingphotosensitizer ATX-S10Na (Ⅱ) are mediated by p53-Bax network and Iow levels of Bcl-2 and Bcl-XL proteins.Our results might help in formulating new therapeutic approaches in photedynamic therapy.

    Purpose: To investigate the technical feasibility of SBRT dose painting using {sup 18}F-NaF positron emission tomography (PET) scans guidance in patients with spine oligometastases from prostate cancer. Methods: As a proof of concept, six patients with 14 spine oligometastatic lesions from prostate cancer who had {sup 18}F-NaF PET/CT scan prior to treatment were retrospectively included. GTV{sub reg} was delineated according to the regular tumor boundary shown on PET and/or CT images; and GTV{sub MATV} was contoured based on a net metabolically active tumor volume (MATV) defined by 60% of the SUV{sub max} values on {sup 18}F-NaF PET images. The PTVs (PTV{sub reg} and PTV{sub MATV}) were defined as respective GTVs (plus involved entire vertebral body for PTV{sub reg}) with a 3-mm isotropic expansion margin. Three 1-fraction SBRT plans using VMAT technique along with 10 MV FFF beams (Plan{sub 24Gy}, Plan{sub 24–27Gy}, and Plan{sub 24–30Gy}) were generated for each patient. All plans included a dose of 24 Gy prescribed to PTV{sub reg}. The Plan{sub 24–27Gy} and Plan{sub 24–30Gy} also included a simultaneous boost dose of 27 Gy or 30 Gy prescribed to the PTV{sub MATV}, respectively. The feasibility of 18F-NaF PET-guided SBRT dose escalation was evaluated by its ability to achieve the prescription dose objectives while adhering to organ-at-risk (OAR) dose constraints. The normal tissue complication probabilities (NTCP) calculated by radiological models were also compared between the plans. Results: In all 33 SBRT plans generated, the planning objectives and dose constraints were met without exception. Plan{sub 24–27Gy} and Plan{sub 24–30Gy} had a significantly higher dose in PTV{sub MATV} than Plan{sub 24Gy} (p < 0.05), respectively, while maintaining a similar OAR sparing profile and NTCP values. Conclusion: Using VMAT with FFF beams to incorporate a simultaneous {sup 18}F-NaF PET-guided radiation boost dose up to 30 Gy into a SBRT plan is technically

    For over thirty years, the IAEA has worked in some 115 low and middle income (LMI) Member States to deploy robust radiotherapy and nuclear medicine programmes, expending over US $250 million on cancer related assistance under its Technical Cooperation Programme, with technical support provided by the Division of Human Health. This has enabled many Member States to establish safe and effective diagnostic imaging and radiation therapy capacity to provide treatment and higher quality care to many of their cancer patients. The IAEA also helps establish new nuclear medicine facilities and encourages their integration with diagnostic radiology procedures by facilitating appropriate human resources capacity building. This helps Member States to achieve and maintain high standards of professional practice. The IAEA addresses quality management though services such as the Quality Assurance in Nuclear Medicine (QUANUM), Quality Assurance Team in Radiation Oncology (QUATRO) and Quality Assurance in Diagnostic Radiology (QUADRIL), which allow the IAEA to provide tools for improving the practice of radiation medicine around the world. In 2004, the IAEA established the Programme of Action for Cancer Therapy (PACT) in support of the World Health Assembly's call to action against cancer. It stands as the IAEA's umbrella programme for combating cancer and builds upon the above experience in radiation medicine expertise and technology. PACT works closely with the World Health Organization (WHO), its regional offices and other key players through the WHO-IAEA Joint Programme on Cancer Control. The WHO-IAEA Joint Programme was established in 2009 to enable LMI Member States to introduce, expand and improve their cancer treatment capacities and therapeutic effectiveness by integrating radiotherapy into a comprehensive national cancer control programme.

    Full Text Available OBJETIVO: Avaliar a prevalência de condutas na prevenção secundária do câncer de mama e fatores associados. MÉTODOS: Foi realizado estudo transversal de base populacional na cidade de Pelotas, RS, em 2002, com amostra de 879 mulheres de 40 a 69 anos. Foram coletadas informações sobre variáveis demográficas, socioeconômicas, comportamentais, biológicas e referentes ao manejo médico. A análise estatística das variáveis foi realizada utilizando o método de regressão de Poisson. RESULTADOS: A prevalência do "hábito de realizar o auto-exame" encontrada foi de 83,5% (IC 95%: 80,9-85,9, sendo que, dessas mulheres, 80,4% (IC 95%: 77,3-83,2 o realizavam ao menos uma vez ao mês. A prevalência de "exame clínico de mamas" foi de 83,3% (IC 95%: 80,6-85,7. "Mamografia alguma vez na vida" mostrou prevalência de 70% (IC 95%: 66,8-73,0, sendo que 83,7% (IC 95%: 80,5-86,6 realizaram a última mamografia há dois anos ou menos. Das entrevistadas, 62% (IC 95%: 58,7-65,2 consultaram ginecologista ao menos uma vez no último ano. Os fatores associados a maiores prevalências das condutas na prevenção secundária do câncer de mama foram: pertencer às classes sociais mais altas; ter a maior combinação de fatores de risco para neoplasia mamária; ter história familiar de câncer de mama; fazer uso de terapia de reposição hormonal e ter sido submetida à biópsia por patologia mamária. CONCLUSÕES: As medidas preventivas para o câncer de mama vêm sendo bastante utilizadas quantitativamente; entretanto, os dados apontam para limitações em relação à sua adequação. O nível socioeconômico parece ser o principal determinante do acesso à consulta ginecológica e, conseqüentemente, às demais condutas na prevenção secundária do câncer de mama.OBJECTIVE: To evaluate the prevalence of secondary prevention of breast cancer and associated factors.

    Cancer is a group of diseases which represents a significant public health problem in Mexico and worldwide. In Mexico neoplasms are the second leading cause of death. An increased morbidity and mortality are expected in the next decades. Several preventable risk factors for cancer development have been identified, the most relevant including tobacco use, which accounts for 30% of the cancer cases; and obesity, associated to another 30%. These factors, in turn, are related to sedentarism, alcohol abuse and imbalanced diets. Some agents are well knokn to cause cancer such as ionizing radiation, viruses such as the papilloma virus (HPV) and hepatitis virus (B and C), and more recently environmental pollution exposure and red meat consumption have been pointed out as carcinogens by the International Agency for Research in Cancer (IARC). The scientific evidence currently available is insufficient to consider milk either as a risk factor or protective factor against different types of cancer. PMID:27603890

    Highlights: • Interstitial lung abnormalities were present in 14% of stage IV NSCLC patients. • ILA was more common in older patients with heavier smoking history. • ILA was associated with shorter survival after adjusting for smoking and therapy. • ILA could be an additional independent marker for survival in advanced NSCLC. - Abstract: Objective: Interstitial lung diseases are associated with increased risk of lung cancer. The prevalence of ILA at diagnosis of advanced non-small-cell lung cancer (NSCLC) and its impact on overall survival (OS) remain to be investigated. Materials and method: The study included 120 treatment-naïve stage IV NSCLC patients (53 males, 67 females). ILA was scored on CT prior to any systemic therapy using a 4-point scale [0 = no evidence of ILA, 1 = equivocal for ILA, 2 = suspicious for ILA, 3 = ILA] by a sequential reading method previously reported. ILA scores of 2 or 3 indicated the presence of ILA. Results: ILA was present in 17 patients (14%) with advanced NSCLC prior to any treatment (score3: n = 2, score2: n = 15). These 17 patients were significantly older (median age: 69 vs. 63, p = 0.04) and had a heavier smoking history (median: 40 vs. 15.5 pack-year, p = 0.003) than those with ILA score 0 or 1. Higher ILA scores were associated with shorter OS (p = 0.001). Median OS of the 17 patients with ILA was 7.2 months [95%CI: 2.9–9.4] compared to 14.8 months [95%CI: 11.1–18.4] in patients with ILA score 0 or 1 (p = 0.002). In a multivariate model, the presence of ILA remained significant for increased risk for death (HR = 2.09, p = 0.028) after adjusting for first-line systemic therapy (chemotherapy, p < 0.001; TKI, p < 0.001; each compared to no therapy) and pack years of smoking (p = 0.40). Conclusion: Radiographic ILA was present in 14% of treatment-naïve advanced NSCLC patients. Higher ILA scores were associated with shorter OS, indicating that ILA could be a marker of shorter survival in advanced NSCLC.

    Background World Health Organization step III opioids are required to relieve moderate-to-severe cancer pain; constipation is one of the most frequent opioid-induced side effects. A fixed combination, prolonged-release oxycodone/naloxone (OXN), was developed with the aim of reducing opioid-related gastrointestinal side effects. The objective of this study was to compare the efficacy and safety of prolonged-release oxycodone (OXY) alone to OXN in opioid-naïve cancer patients with moderate-to-severe pain. Methods Propensity analysis was utilized in this observational study, which evaluated the efficacy, safety, and quality of life. Results Out of the 210 patients recruited, 146 were matched using propensity scores and included in the comparative analysis. In both groups, pain intensity decreased by ≈3 points after 60 days, indicating comparable analgesic efficacy. Responder rates were similar between groups. Analgesia was achieved and maintained with similarly low and stable dosages over time (12.0–20.4 mg/d for OXY and 11.5–22.0 mg/d for OXN). Bowel Function Index (BFI) and laxative use per week improved from baseline at 30 days and 60 days in OXN recipients (−16, P<0.0001 and −3.5, P=0.02, respectively); BFI worsened in the OXY group. The overall incidence of drug-related adverse events was 28.9% in the OXY group and 8.2% in the OXN group (P<0.01); nausea and vomiting were two to five times less frequent with OXN. Quality of life improved to a significantly greater extent in patients receiving OXN compared to OXY (increase in Short Form-36 physical component score of 7.1 points vs 3.2 points, respectively; P<0.001). Conclusion In patients with chronic cancer pain, OXN provided analgesic effectiveness that is similar to OXY, with early and sustained benefits in tolerability. The relationship between responsiveness to OXN and clinical characteristics is currently being investigated. PMID:26586937

    Radiotherapy may result in endocrine abnormalities, osteoporosis, obesity and neurological sequelae in patients treated for cancer. In the hypothalamo-pituitary area, GH deficiency is the most frequent complication. The frequency, delay of appearance and severity of GH deficiency depend most on the dose delivered during cranial irradiation but variables as age at treatment and fractionation schedule may play an important role as well. Other hypothalamo-pituitary dysfunctions are also dose-dependent. Low dose cranial irradiation may induce precocious or early puberty, while high doses are related to gonadotropin deficiency. Endocrine complications due to extracranial irradiation such as gonadal or thyroid abnormalities are described. In spite of normal GH secretion, linear growth may be impaired by bone lesions secondary to craniospinal or total body irradiation. Results on final height have been optimized by better indicators of GH therapy associated with adequate treatment of early or precocious puberty. The purpose of this review is to explore the late endocrine sequelae of radiotherapy. (author)

    The human exposure to ionizing radiation coming from natural sources is an inherent feature of human life on earth, for man and all living things have always been exposed to these sources. Ionizing radiation is a known genotoxic agent which can affect the genomic stability and genes related to DNA repair may play a role when they have committed certain polymorphism. This study aimed to analyze the frequency of polymorphisms (SNPs) in genes of DNA repair and cell cycle control: hOGG1 (Ser326Cys), XRCC3 (Thr241 Met) and p53 (Arg72Pro) in saliva samples from a population located Monte Alegre, state of Para were collected in August 2008 and 40 samples of men and 46 samples of women, adding a total of 86 samples. By RFLP was determined the frequency of homozygous genotypes and / or heterozygous for polymorphic genes. The I)OGG1 gene was 5% of the allele 326Cys, XRCC3 gene found about 21 % of the allele 241 Met and p53 gene showed 40.8% of the 72Pro allele. And the genotype frequencies of individuals for the three genes were 91.04%, 88.06% and 59.7% for homozygous wild genotype, 5.97%, 11.94% and 22.39% for heterozygote genotype and 2,99%, zero and 17:91% for homozygous polymorphic hOGG1 genes respectively, XRCC3, p53. These values are similar to those found in previous studies. The influence of these polymorphisms, which are involved in DNA repair and consequent genotoxicity induced by radiation depends on dose and exposure factors such as smoking, which is statistically a factor in public health surveillance in the region. This study gathered information and molecular epidemiology in Monte Alegre, that help to characterization of local population. (author)

    Full Text Available There are many carcinogenetic elements in industry and it is for this reason that study and research concerning the effect of these materials is carried out on a national and international level. The establishment and growth of cancer are affected by different factors in two main areas:-1 The nature of the human or animal including sex, age, point and method of entry, fat metabolism, place of agglomeration of carcinogenetic material, amount of material absorbed by the body and the immunity of the body.2 The different nature of the carcinogenetic material e.g. physical, chemical quality, degree of solvency in fat and purity of impurity of the element. As the development of cancer is dependent upon so many factors, it is extremely difficult to determine whether a causative element is principle or contributory. Some materials are not carcinogenetic when they are pure but become so when they combine with other elements. All of this creates an industrial health problem in that it is almost impossible to plan an adequate prevention and safety program. The body through its system of immunity protects itself against small amounts of carcinogens but when this amount increases and reaches a certain level the body is not longer able to defend itself. ILO advises an effective protection campaign against cancer based on the Well –equipped laboratories, Well-educated personnel, the establishment of industrial hygiene within factories, the regular control of safety systems, and the implementation of industrial health principles and research programs.

    Summary Mammalian colon harbors trillions of bacteria under physiologic conditions; this symbiosis is made possible because of a tolerized response from the mucosal immune system. The mechanisms underlying this tolerogenic phenomenon remain poorly understood. Here we show that Slc5a8, a Na+-coupled high-affinity transporter in colon for the bacterial fermentation product butyrate, plays a critical role in this process. Among various immune cells in colon, dendritic cells (DCs) are unique not only in their accessibility to luminal contents but also in their ability to induce tolerogenic phenotype in T cells. We found that DCs exposed to butyrate express the immunosuppressive enzymes indoleamine 2,3-dioxygenase 1 (IDO1) and aldehyde dehydrogenase 1A2 (Aldh1A2), promote conversion of naïve T cells into immunosuppressive FoxP3+ Tregs, and suppress conversion of naïve T cells into pro-inflammatory IFN-γ-producing cells. Slc5a8-null DCs do not induce IDO1 and Aldh1A2 and do not generate Tregs or suppress IFN-γ-producing T cells in response to butyrate. We also provide in vivo evidence for an obligatory role for Slc5a8 in suppression of IFN-γ-producing T cells. Furthermore, Slc5a8 protects against colitis and colon cancer under conditions of low-fiber intake but not when dietary fiber intake is optimal. This agrees with the high-affinity nature of the transporter to mediate butyrate entry into cells. We conclude that Slc5a8 is an obligatory link between dietary fiber and mucosal immune system via the bacterial metabolite butyrate, and that this transporter is a conditional tumor suppressor in colon linked to dietary fiber content.

Of 150 patients with localized prostate cancer (T1c–T2c), 59 underwent HDR brachytherapy plus EBRT, and 91 received radical prostatectomy. The median follow-up of patients was 62 months for HDR brachytherapy plus EBRT, and 64 months for radical prostatectomy. In patient backgrounds between the two cohorts, the frequency of T2b plus T2c was greater in HDR brachytherapy cohort than in prostatectomy cohort (27% versus 12%, p = 0.029). Patients in HDR brachytherapy cohort first underwent 3D conformal RT with four beams to the prostate to an isocentric dose of 50 Gy in 25 fractions and then, a total of 15–18 Gy in two fractions at least 5 hours apart. We prescribed 9 Gy/fraction for target (prostate gland plus 3 mm lateral outside margin and seminal vesicle) using CT image method for radiation planning. The total biochemical failure-free control rates (BF-FCR) at 3 and 5 years for the HDR brachytherapy cohort, and for the prostatectomy cohort were 92% and 85%, and 72% and 72%, respectively (significant difference, p = 0.0012). The 3-and 5-year BF-FCR in the HDR brachytherapy cohort and in the prostatectomy cohort by risk group was 100 and 100%, and 80 and 80%, respectively, for the low-risk group (p = 0.1418); 92 and 92%, 73 and 73%, respectively, for the intermediate-risk group (p = 0.0492); and 94 and 72%, 45 and 45%, respectively, for the high-risk group (p = 0.0073). After HDR brachytherapy plus EBRT, no patient experienced Grade 2 or greater genitourinay toxicity. The rate of late Grade 1 and 2 GI toxicity was 6% (n = 4). No patient experienced Grade 3 GI toxicity. HDR brachytherapy plus EBRT is useful for treating patients with hormone-naïve localized prostate cancer, and has low GU and GI toxicities

    It is known that more than 20% of the world's population will contract some type of cancer. In Brazil, with the exception of skin cancer (non melanoma) the breast cancer ranks first among the higher frequency of tumours among women and in general, although the methods of detection are advancing in the year 2010 took place about 13 thousand deaths in about 50,000 cases, probably due to late detection of these neoplasm. New cases of breast cancer in a given population can be proven from absorbed dose quantity, calculated for the compressed breast, due to the risk by means of exposure to x rays in this radiodiagnostic practices. Methodology: Exposures were held in an ionization chamber and the other quantities required were obtained to the screen-film equipment of mammography. Results: Also experimental results were of compressed breast an equivalent dose of ( 1.82 mSv {+-} 0.2%) or (3.64 mSv {+-} 0.2%) for both projections, i.e. medium lateral oblique and cranio caudal. The experimental value obtained here is consistent with the calculated results and published in the literature for analog and CR equipment. Conclusion: From the result of dose equivalent in the breast, one can say that there will be effectively attesting as to the appearance of new cases of cancer if approximately 80 million women are exposed to radiation emitted by mammographers.

    Full Text Available O estudo objetivou compreender como o sertanejo com câncer lida com a morte. Três temáticas foram entrelaçadas nesta pesquisa: a morte em seus aspectos históricos e psicológicos; a realidade histórico-cultural do homem do sertão nordestino brasileiro; e a pessoa com câncer em sociedade. Utilizou-se uma abordagem qualitativa e método fenomenológico, os instrumentos de coleta de dados foram: a observação participante e a entrevista fenomenológica. Concluiu-se que a população pesquisada percebe a morte com mais familiaridade, que as formas de enfrentamento perpassam pela fé, que a vivência do adoecimento é modulada por aspectos psicossociais e culturais e que os rituais funerários tradicionais estão sendo modificados diante de uma lógica de mercantilização da morte.This study aimed to understand how the backcountry with cancer sees death. Three themes were interwoven in this research: death in its historical and psychological aspects; the historical and cultural realities of man's Northeast Backcountry of Brazil, and the person with cancer in society. A qualitive approach and the critical phenomenological method were used, having as instruments of data collection the participant observation and phenomenological interview. It was concluded that the backcountry perceives death with more familiarity, that permeate the ways of coping through faith, that the experience of illness is modulated by psychosocial and cultural aspects and traditional funeral rituals are being modified facing logic of merchantilizing of the death.

    Purpose This post hoc analysis evaluated treatment effects, safety, and pharmacokinetics of enzalutamide in Korean patients in the phase 3, double-blind, placebo-controlled PREVAIL trial. Materials and Methods Asymptomatic or mildly symptomatic chemotherapy-naive men with metastatic castration-resistant prostate cancer that progressed on androgen deprivation therapy received 160 mg/d oral enzalutamide or placebo (1:1) until death or discontinuation due to radiographic progression or skeletal-related event and initiation of subsequent therapy. Coprimary end points were centrally assessed radiographic progression-free survival (rPFS) and overall survival (OS). Secondary end points included investigator-assessed rPFS, time to initiation of chemotherapy, time to prostate-specific antigen (PSA) progression, PSA response (≥50% decline), and time to skeletal-related event. Results Of 1,717 total patients, 78 patients were enrolled in Korea (enzalutamide, n=40; placebo, n=38). Hazard ratios (95% confidence interval) for enzalutamide versus placebo were 0.23 (0.02–2.24) for centrally assessed rPFS, 0.77 (0.28–2.15) for OS, 0.21 (0.08–0.51) for time to chemotherapy, and 0.31 (0.17–0.56) for time to PSA progression. A PSA response was observed in 70.0% of enzalutamide-treated and 10.5% of placebo-treated Korean patients. Adverse events of grade ≥3 occurred in 33% of enzalutamide-treated and 11% of placebo-treated Korean patients, with median treatment durations of 13.0 and 5.1 months, respectively. At 13 weeks, the plasma concentration of enzalutamide plus N-desmethyl enzalutamide was similar in Korean and non-Korean patients (geometric mean ratio, 1.04; 90% confidence interval, 0.97–1.10). Conclusions In Korean patients, treatment effects and safety of enzalutamide were consistent with those observed in the overall PREVAIL study population (ClinicalTrials.gov Identifier: NCT01212991).

    Mammalian colon harbours trillions of bacteria under physiological conditions; this symbiosis is made possible because of a tolerized response from the mucosal immune system. The mechanisms underlying this tolerogenic phenomenon remain poorly understood. In the present study we show that Slc5a8 (solute carrier gene family 5a, member 8), a Na(+)-coupled high-affinity transporter in colon for the bacterial fermentation product butyrate, plays a critical role in this process. Among various immune cells in colon, dendritic cells (DCs) are unique not only in their accessibility to luminal contents but also in their ability to induce tolerogenic phenotype in T-cells. We found that DCs exposed to butyrate express the immunosuppressive enzymes indoleamine 2,3-dioxygenase 1 (IDO1) and aldehyde dehydrogenase 1A2 (Aldh1A2), promote conversion of naive T-cells into immunosuppressive forkhead box P3(+) (FoxP3(+)) Tregs (regulatory T-cells) and suppress conversion of naive T-cells into pro-inflammatory interferon (IFN)-γ-producing cells. Slc5a8-null DCs do not induce IDO1 and Aldh1A2 and do not generate Tregs or suppress IFN-γ-producing T-cells in response to butyrate. We also provide in vivo evidence for an obligatory role for Slc5a8 in suppression of IFN-γ-producing T-cells. Furthermore, Slc5a8 protects against colitis and colon cancer under conditions of low-fibre intake but not when dietary fibre intake is optimal. This agrees with the high-affinity nature of the transporter to mediate butyrate entry into cells. We conclude that Slc5a8 is an obligatory link between dietary fibre and mucosal immune system via the bacterial metabolite butyrate and that this transporter is a conditional tumour suppressor in colon linked to dietary fibre content.

NA49 is one of the seven experiments (NA44, NA45, NA49, NA50, NA52, WA97/NA57 and WA98) involved in CERN's Heavy Ion programme which provided evidence for the existence of a new state of matte, the quark-gluon plasma. In this state, quarks, instead of being bound up into more complex particles such as protons and neutrons, are liberated and roam freely. Theory predicts that this state must have existed at about 10 microseconds after the Big Bang, before the formation of matter as we know it today.

    Herein, we report the fabrication of a multifunctional nanoprobe based on highly monodispersed, optically and magnetically active, biocompatible, PEI-functionalized, highly crystalline β-NaYF4:Gd3+/Tb3+ nanorods as an excellent multi-modal optical/magnetic imaging tool and a pH-triggered intracellular drug delivery nanovehicle. The static and dynamic photoluminescence spectroscopy showed the presence of sharp emission peaks, with long lifetimes (~3.5 milliseconds), suitable for optical imaging. The static magnetic susceptibility measurements at room temperature showed a strong paramagnetic signal (χ ~ 3.8 × 10-5 emu g-1 Oe-1). The nuclear magnetic resonance (NMR) measurements showed fair T1 relaxivity (r1 = 1.14 s-1 mM-1) and magnetic resonance imaging gave enhanced T1-weighted MRI images with increased concentrations of β-NaYF4:Gd3+/Tb3+ making them suitable for simultaneous magnetic resonance imaging. In addition, an anticancer drug, doxorubicin (DOX) was conjugated to the amine-functionalized β-NaYF4:Gd3+/Tb3+ nanorods via pH-sensitive hydrazone bond linkages enabling them as a pH-triggered, site-specific drug delivery nanovehicle for DOX release inside tumor cells. A comparison between in vitro DOX release studies undertaken in normal physiological (pH 7.4) and acidic (pH 5.0) environments showed an enhanced DOX dissociation (~80%) at pH 5.0. The multifunctional material was also applied as an optical probe to confirm the conjugation of DOX and to monitor DOX release via a fluorescence resonance energy transfer (FRET) mechanism. The DOX-conjugated β-NaYF4:Gd3+/Tb3+ nanorods exhibited a cytotoxic effect on MCF-7 breast cancer cells and their uptake by MCF-7 cells was demonstrated using confocal laser scanning microscopy and flow cytometry. The comparative cellular uptakes of free DOX and DOX-conjugated β-NaYF4:Gd3+/Tb3+ nanorods were studied in tumor microenvironment conditions (pH 6.5) using confocal imaging, which showed an increased uptake of DOX

Tal condição predispõe o paciente ao maior risco de infecções, pior resposta aos tratamentos implantados e, como conseqüência, desfavorece o prognóstico de cura. Além disso, a desnutrição também está associada à pior qualidade de vida. Dessa forma, algumas terapias têm sido propostas na tentativa de reverter o catabolismo, por meio da atenuação da resposta inflamatória, observado em grande porcentagem de pacientes com câncer e caquexia. Entre elas, a suplementação com ácidos graxos da família ômega-3 pode representar uma estratégia na redução da formação de citocinas pró-inflamatórias, favorecendo a tolerância metabólica dos substratos energéticos e atenuando o catabolismo protéico, com o intuito de melhorar o prognóstico de cura de pacientes com câncer. Entretanto, os estudos mostram alguns resultados conflitantes da suplementação com ômega-3 na resposta imunológica. Por outro lado, em pacientes com câncer, os ensaios clínicos mostraram atenuar a resposta inflamatória e melhorar o estado nutricional. O objetivo deste artigo é realizar uma revisão criteriosa do assunto.Emaciation and loss of lean body mass is a frequent phenomenon observed in cancer patients. This condition leads to infection risk and a poor response to treatment, thus reducing the chances of cure. Furthermore, malnutrition is also associated with a poor quality of life. Therefore, therapies have been proposed in attempt to revert the catabolism observed in most of these patients by attenuating the inflammatory response. Among them, omega-3 fatty acid supplementation may be a strategy to reduce the production of pro-inflammatory cytokines and improve metabolic substrate tolerance, decreasing protein catabolism in order to ameliorate the prognosis of cure in cancer patients. However, studies demonstrate some

    Full Text Available A importância das doenças oncológicas como causa de morbilidade e mortalidade está em crescimento, sendo reconhecido o seu impacto social e peso global pelos custos económicos e sociais envolvidos na sua prevenção, tratamento e reabilitação. As patologias oncológicas de cabeça e pescoço representam um dos seis tumores malignos mais prevalentes em todo o mundo, com um valor estimado de 900.000 novos casos diagnosticados anualmente em escala mundial. Estes doentes oncológicos apresentam deterioração de funções básicas que, quando percepcionadas, têm impacto negativo na sua Qualidade de Vida. Um registo oncológico adequado permite uma análise mais rigorosa dos resultados obtidos na avaliação da Qualidade de Vida Relacionada com a Saúde. Este estudo incluiu 380 doentes oncológicos de cabeça e pescoço e demonstra que as mulheres apresentam resultados de Qualidade de Vida globalmente inferiores. Salienta-se ainda a importância do diagnóstico precoce em oncologia, que se relaciona frequentemente com melhores scores e conclui-se que a localização do tumor tem impacto sobre a autopercepção de Qualidade de Vida. Os valores de Qualidade de Vida Relacionada com a Saúde devem ser interpretados à luz das variáveis sociodemográficas e clínicas, para melhor se avaliar a Patologia Oncológica de Cabeça e Pescoço numa perspectiva epidemiológica no sentido de melhor compreender o processo saúde - doença.The importance of oncology diseases as a cause of morbidity and mortality is increasing worldwide, and their social impact is being recognized due to economic and social costs involved in prevention, treatment and rehabilitation.

    The human exposure to ionizing radiation coming from natural sources is an inherent feature of human life on Earth. Ionizing radiation is a known genotoxic agent, which can affect biological molecules, causing DNA damage and genomic instability. The cellular system of DNA repair plays an important role in maintaining genomic stability by repairing DNA damage caused by genotoxic agents. However, genes related to DNA repair may have their role committed when presenting a certain polymorphism. This study intended to analyze the frequency of single nucleotide polymorphisms (SNPs) in genes of DNA repair XRCC1 (Arg39-9Gln) and XPD (Lys751Gln) in a: population of the city of Monte Alegre, that resides in an area of high exposure to natural radioactivity. Samples of saliva were collected from individuals of the population of Monte Alegre, in which 40 samples were of male and 46 female. Through the use of RFLP (length polymorphism restriction fragment) the frequency of homozygous genotypes and / or heterozygous was determined for polymorphic genes. The XRCC1 gene had 65.4% of the presence of the allele 399Gln and XPD gene had 32.9% of the 751Gln allele. These values are similar to those found in previous studies for the XPD gene, whereas XRCC1 showed a frequency much higher than described in the literature. The. influence of these polymorphisms, which are involved in DNA repair and consequent genotoxicity induced by radiation depends on dose and exposure factors such as smoking, statistically a factor in public health surveillance in the region. This study gathered information and molecular epidemiology for risk assessment of cancer in the population of Monte Alegre. (author)

    Cancer patients under treatment of head and neck tumors as well as those under chemotherapy for hematologic cancers, such as lymphoma and leukemia, and those about to receive bone marrow grafts, do require preventive oral and dental care (prior to cancer treatment), as well as oral care during and after oncological treatment. Furthermore, chemo and radiotherapy-related adverse effects are also common in patients with other types of cancer, with an estimated frequency of 10 per cent in adjuvant chemotherapy (QT), 40 per cent in primary QT, 80 per cent in bone marrow transplantation, in which myeloablative regimens are introduced, and 100 per cent in head and neck radiotherapy, in which the targeted fields are those of the oral cavity. The dentist, specialized in dental oncology, works within the multidisciplinary team at the great centers of cancer treatment, contributing to improve the quality of life of these patients. The present review of literature and of the Guidelines for Management of Oral Complications of Chemotherapy and Head and Neck Radiation (US National Cancer Institute) aims to inform the clinical oncologist, the radio therapist, and other professionals about the resources available in Oral Supportive Therapy in both the prevention and managements of such complications.

    Glucocorticoids are commonly used as palliative or chemotherapeutic clinical agents for treatment of a variety of cancers. Although steroid treatment is beneficial, the mechanisms by which steroids improve outcome in cancer patients are not well understood. Na,K-ATPase beta-subunit isoform 1 (NaK-β1) is a cell-cell adhesion molecule, and its expression is down-regulated in cancer cells undergoing epithelial-to mesenchymal-transition (EMT), a key event associated with cancer progression to metastatic disease. In this study, we performed high-throughput screening to identify small molecules that could up-regulate NaK-β1 expression in cancer cells. Compounds related to the glucocorticoids were identified as drug candidates enhancing NaK-β1 expression. Of these compounds, triamcinolone, dexamethasone, and fluorometholone were validated to increase NaK-β1 expression at the cell surface, enhance cell-cell adhesion, attenuate motility and invasiveness and induce mesenchymal to epithelial like transition of renal cell carcinoma (RCC) cells in vitro. Treatment of NaK-β1 knockdown cells with these drug candidates confirmed that these compounds mediate their effects through up-regulating NaK-β1. Furthermore, we demonstrated that these compounds attenuate tumor growth in subcutaneous RCC xenografts and reduce local invasiveness in orthotopically-implanted tumors. Our results strongly indicate that the addition of glucocorticoids in the treatment of RCC may improve outcome for RCC patients by augmenting NaK-β1 cell-cell adhesion function. PMID:25836370

    Full Text Available RATIONALE: Since ovarian function is only temporarily compromised by radioiodine therapy, many women with thyroid cancer treated with radioiodine can become pregnant. The present study evaluated the evolution of these pregnancies and the consequences for the offspring. PATIENTS AND METHODS: We retrospectively analyzed 78 pregnancies of 66 women submitted to total thyroidectomy, followed by radioiodine therapy (3.7­5.5 GBq 131I, mean 4.64 GBq. In all patients, conception occurred one year after ablative therapy (mean of 30 months. Age ranged form 19 to 36 years (mean of 30.6 years at the time of radioiodine treatment and from 23 to 39 years (mean of 32.8 years at the time of conception. RESULTS: Four (5.1% of the 78 pregnancies resulted in spontaneous abortions. Three (4% of the 74 deliveries were preterm and there was no case of stillbirth. The birthweight was > 2500 g in 94.6% of the children (mean ± SD: 3350 ± 450 g and only one infant (1.3% presented an apparent malformation at birth (intraventricular communication. No difference in the age at the time of radioiodine therapy or conception or in radioiodine dose was observed between pregnancies with an unfavorable outcome and those with a favorable outcome. CONCLUSION: We conclude that pregnancies that occur 12 months after ablative therapy are safe.ARRAZOADO: Uma vez que a função ovariana está apenas temporariamente comprometida pela terapia com radioiodo, muitas mulheres com câncer de tireóide tratadas com radioiodo podem engravidar.

    Cancer screening is a means to detect cancer early with the goal of decreasing morbidity and mortality. At present, there is a reasonable consensus regarding screening for breast, cervical and colorectal cances and the role of screening is under trial in case of cancers of the lung,  ovaries and prostate. On the other hand, good screening tests are not available for some of the commonest cancers in India like the oral, pharyngeal, esophageal and stomach cancers.

  9. Measurement of exchangeable sodium: 22Na or 24Na

    International Nuclear Information System (INIS)

    A case is made for the use of 22Na in low activities in preference to 24Na for routine diagnostic estimation of exchangeable sodium, and is based chiefly on considerations of availability, cost and radiation dosimetry. A method in which only 37 kBq (1 μCi) 22Na is administered orally is shown to be sufficiently accurate and to possess distinct advantages in terms of cost and convenience with a committed radiation dose no greater than that for a measurement using 24Na.

    Full Text Available MicroRNAs (miRNAs representam uma nova classe de RNAs endógenos de ~22 nucleotídeos, que atuam como silenciadores pós-transcricionais, inibindo a tradução de RNAs mensageiros-alvo. Descobertos há pouco mais de uma década em Caenorhabditis elegans, os miRNAs são hoje reconhecidos como reguladores fundamentais da expressão gênica em plantas e animais. Até o momento, identificaram-se 462 genes de miRNA no genoma humano e estima-se que esse número supere 1000 miRNAs distintos. Análises bioinformáticas indicam que um único miRNA atue em diversos RNAs mensageiros, influenciando múltiplas vias de sinalização concomitantemente e apresentando enorme potencial regulatório. Apesar da biologia dos miRNAs ser ainda pouco entendida, essas moléculas já foram relacionadas a diversos processos biológicos. Além disso, a expressão anômala destes pequenos RNAs tem sido associada a diferentes patologias humanas, inclusive aquelas relacionadas ao sistema endócrino e câncer.MicroRNAs (miRNAs represent a novel class of endogenous ~22-nucleotide RNAs that negatively regulate gene expression by inhibiting translation of target RNAs. Discovered just over a decade ago in Caenorhabditis elegans, miRNAs are now recognized as one of the major regulatory gene families in plants and animals. In the human genome, 462 miRNA genes have been discovered and the estimated number of miRNAs is as high as 1000. Bioinformatics analysis indicated that a unique miRNA acts on several mRNA, influencing multiple signaling pathways concomitantly, thus presenting enormous regulatory potential. Although the biology of miRNAs is not well understood, recent evidences have linked these molecules to diverse biological processes. Moreover, aberrant expression of miRNAs has been associated to human disease, including that related to the endocrine system and cancer.

    The usefulness of fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) in differentiated thyroid cancer (DTC) has been demonstrated by many investigators, but in only a small number of studies have FDG-PET images been compared with those obtained using other non-iodine tumour-seeking radiopharmaceuticals. In most of the studies, planar imaging was performed for comparison using thallium-201 chloride or technetium-99m 2-methoxyisobutylisonitrile ({sup 99m}Tc-MIBI). Furthermore, FDG-PET studies were not always performed in the hypothyroid state with increased levels of thyroid stimulating hormone (TSH), which are known to increase FDG uptake by DTC. The aim of this study was to compare the ability of FDG-PET to detect metastatic DTC with that of {sup 99m}Tc-MIBI whole-body single-photon emission tomography (SPET) and post-therapeutic iodine-131 scintigraphy, evaluated under TSH stimulation. Nineteen patients (8 men, 11 women; age range, 38-72 years, mean 60 years; 17 thyroidectomised and 2 inoperable patients following {sup 131}I ablation of the remaining thyroid tissue; 16 papillary and 3 follicular carcinomas) with metastatic DTC underwent FDG-PET whole-body scan (WBS) and {sup 99m}Tc-MIBI SPET WBS at an interval of less than 1 week, followed by {sup 131}I therapy. The SPET images were reconstructed using the maximum likelihood expectation maximisation (ML-EM) method. All patients were hypothyroid at the time of each scan. {sup 131}I WBS was performed 3-5 days after oral administration of the therapeutic dose. A total of 32 lesions [10 lymph node (LN), 15 lung, 6 bone, 1 muscle] were diagnosed as metastases, as confirmed by histopathology and/or other imaging modalities (X-ray, US, CT, MRI, bone, {sup 201}Tl and {sup 131}I scans). FDG-PET, {sup 99m}Tc-MIBI SPET and post-therapeutic {sup 131}I scintigraphy respectively revealed a total of 26 (81.3%), 20 (62.5%) and 22 (68.8%) lesions.

    Quando viam um cometa, os antigos gregos imaginavam uma estrela com uma vasta cabeleira. Não à toa, a palavra deriva do termo koma, que significa cabelo. Constituídos por fragmentos de gelo e gases, os cometas possuem um núcleo sólido, que pode ter vários quilômetros de diâmetro, e uma cauda que sempre aponta na direção contrária ao Sol, devido aos ventos solares. Graças à aparência de pontos luminosos em movimento (ao contrário de outros astros, que parecem estáticos), esses corpos celestes foram interpretados por diferentes povos com muito misticismo, inspirando mitos tanto de boas-novas como de maus presságios.

  17. NA48 prototype calorimeter

    CERN Multimedia

    1990-01-01

    This is a calorimeter, a detector which measures the energy of particles. When in use, it is filled with liquid krypton at -152°C. Electrons and photons passing through interact with the krypton, creating a shower of charged particles which are collected on the copper ribbons. The ribbons are aligned to an accuracy of a tenth of a millimetre. The folding at each end allows them to be kept absolutely flat. Each shower of particles also creates a signal in scintillating material embedded in the support disks. These flashes of light are transmitted to electronics by the optical fibres along the side of the detector. They give the time at which the interaction occurred. The photo shows the calorimeter at NA48, a CERN experiment which is trying to understand the lack of anti-matter in the Universe today.

  2. Energy levels of 24Na

    International Nuclear Information System (INIS)

    Four experiments are reported yielding excitation energies, spins, parities, mean lifetimes, γ-ray branching ratios of 24Na. The applied methods include particle-γ angular correlations and Doppler shift attenuation method lifetime measurements. From a 23Na(d,pγ)24Na experiments using a large Ge(Li) γ-detector excitation energies, branching ratios and mean lifetimes are determined. A 26Mg(d,αγ)24Na experiment using a NaI(Te) γ-detector enables the assignment of spins and γ-ray mixing ratios. From a 22Ne(3He,pγ)24Na measurement with a deeply implanted 22Ne target, preliminary data from the γ-decay of levels with Ex = 4 - 6 meV and additional nuclear lifetime data are decided. Finally a 23Na(n,γ)24Na γ-spectrum obtained with thermal neutrons and a Ge(Li) detector enabled the adjustment of some of the level energies. The data from these and other experiments were collected and compared with theory. It turned out that the statistical model of nuclear reactions does not give reliable information about nuclear spin-parity combinations. However recent shell-model calculations of Chung give remarkable agreement for low-lying levels (Ex < 3.3 meV)

    Full Text Available Neste texto pretende-se discorrer sobre valores morais na escola e suas implicações para a formação de professores. Para tanto discutir-se-á, em primeiro lugar, e brevemente, o que são valores morais, ou éticos, e como a escola pode situar-se em relação a eles. Em seguida, serão relatadas algumas observações a respeito de valores de professores e práticas daí decorrentes. São comentados resultados de pesquisa que ilustram a transmissão de valores de forma doutrinal e a educação moral e cívica tal como realizada na ditadura militar, e, por outro lado, a posição relativista e/ou de laissez-faire que certas escolas podem adotar, metodologicamente, sobre a educação em valores. Finalmente, defender-se-á a idéia de que é necessária uma discussão sobre valores pelos diversos membros da escola e uma opção por uma metodologia para ensiná-los, seja os professores, em sua formação inicial e continuada, seja os alunos. A teoria de desenvolvimento moral de Jean Piaget será apresentada como uma referência possível para a educação em valores. Exemplos de situações escolares de conflito de valores entre direção, pais e alunos são discutidas para ilustrar como uma escola pode adotar um procedimento democrático de educação em valores, que se apresenta como um terceiro caminho possível de educação moral nas escolas, além das posições doutrinárias ou relativistas.

    Full Text Available Precancerous lesions and skin cancer are infrequent in Asians, and have received little documentation in the literature. Brazil has the world's largest contingent of Japanese immigrants and their descendants, and 70% live in the State of São Paulo. The prevalence of such skin lesions in Japanese-Brazilians is unknown. This study aimed to assess the prevalence of actinic keratoses and non-melanoma skin cancer in first and second-generation Japanese-Brazilians over 30 years of age, without miscegenation, living in the city of Bauru, São Paulo State, in 2006. Of the 567 Japanese-Brazilians that underwent dermatological examination, actinic keratosis was diagnosed in 76, with a mean age of 68.9 years, and a single case of basal cell carcinoma was detected in a 39-year-old female patient. In Japan, prevalence of actinic keratosis varies from 0.76% to 5%, and the incidence of non-melanoma skin cancer is 1.2 to 5.4/100 thousand. Japanese-Brazilians from Bauru showed a 13.4% prevalence of actinic keratoses and earlier age at onset. Proximity to the Equator and a history of farming contribute to these higher rates. Presence of solar melanosis was associated with a 1.9-fold risk of developing actinic keratosis.Manifestações cutâneas pré-neoplásicas e neoplásicas em asiáticos são infreqüentes e pouco documentadas. O Brasil possui o maior contingente de imigrantes japoneses e 70% deles residem no Estado de São Paulo. A prevalência dessas lesões em nipo-brasileiros é desconhecida.

  16. A aposta na filosofia

    Directory of Open Access Journals (Sweden)

    Márcio Suzuki

    2011-12-01

    Full Text Available Para Hume, filosofar é uma atividade semelhante às demais ocupações humanas. A decisão que leva à atividade filosófica é menos resultado de uma argumentação teórica do que fruto de um cálculo prático, que é entendido como uma caça ou um jogo. O objetivo deste trabalho será o de mostrar que no jogo filosófico perde quem joga sério demais. A aposta na filosofia tem que passar pelo bom humor e pela diversão: uma resposta a Pascal?For Hume, philosophy is in itself neither more nor less important than other human activities. On the contrary, it can be explained from its resemblance with game and hunting. If one chooses to dedicate himself to philosophy, his decision is not the consequence of logical reasoning, but depends on practical evaluation, which has something to do with gambling. The following text tries to show that in philosophy, like in other games, the loser will be the one who plays too earnestly. The philosophical game requires good humour and some relaxation: Is this a good answer to Pascal's pari?

    Full Text Available Naturally occurring tumors in dogs are well-established models for several human cancers. Domestic cats share many of the benefits of dogs as a model (spontaneous cancers developing in an immunocompetent animal sharing the same environment as humans, shorter lifespan allowing more rapid trial completion and data collection, lack of standard of care for many cancers allowing evaluation of therapies in treatment-naïve populations, but have not been utilized to the same degree in the One Medicine approach to cancer. There are both challenges and opportunities in feline compared to canine models. This review will discuss three specific tumor types where cats may offer insights into human cancers. Feline oral squamous cell carcinoma is common, shares both clinical and molecular features with human head and neck cancer and is an attractive model for evaluating new therapies. Feline mammary tumors are usually malignant and aggressive, with the ‘triple-negative’ phenotype being more common than in humans, offering an enriched population in which to examine potential targets and treatments. Finally, although there is not an exact corollary in humans, feline injection site sarcoma may be a model for inflammation-driven tumorigenesis, offering opportunities for studying variations in individual susceptibility as well as preventative and therapeutic strategies.

    Full Text Available INTRODUCTION: stem cells may originate and perpetuate the tumor growth, but they are poorly known in gliomagenesis. Metallothioneins (MTs are proteins involved in oncogenesis and immunopositivity, for MT may be used as a stem cell mutation marker. OBJECTIVE: to study the MT expression in the ENU experimental model and to establish an experimental model to track glioma stem cells in early oncogenesis. METHODS: Thirty-six male Wistar rats were divided into two groups; the experimental group was treated within 24 hours after birth (neonate rats with a single dose of subcutaneously injected N-ethyl N-nitrosourea ENU (40 mg/kg body weight. The control animals were injected with the same volume of saline. These experimental animals were subdivided into three groups according to the euthanize time, as follows: the Group 1 (G1 was euthanized at the age of 30 days; the Group 2 (G2, at the age of 180 days and the Group 3 (G3 was euthanized soon after the appearing of signs of the existence of nervous system tumors, at an average age of 321 days. Immunohistochemical detection of MT protein in cold acetone-fixed paraffin embedded spine cord sections was performed by the streptavidin-avidin-biotin-immuno peroxidase complex method. RESULTS: by using the experimental model of gliomagenesis induced by the N-ethyl N-nitrosourea, it was possible to detect putative tumor stem cells in early oncogenesis, to analyze a field cancerization process and to observe a close morphological relationship between MT positive cells and blood vessels. CONCLUSIONS: this reproducible experimental model allows further studies on the origins, development and regulating factors involved in gliomagenesis.INTRODUCCIÓN: células madre pueden originar y perpetuar el crecimiento tumoral, sin embargo son poco conocidas en la gliomagénesis.

    2004-01-01

    Background We asssessed whether the CaNa2 EDTA could improve the accumulation of protoporphyrin Ⅸ (PpⅨ) and photosensitisation in HEp-2 cells as well as the depth of treatment of skin cancers on the topical 5-Aminolaevulinic acid (5-ALA) PDT.Methods HEp-2 cells were incubated with 5-ALA (0-1mmol/L) and CaNa2EDTA (0-1mmol/L) for 4 hours, intracellular protoporphyrin Ⅸ content was quantified by extraction, and cell viability was assessed by use of the methyl-tetrazolium (MTT) assay four hours after exposure to light. In comparison with the pictures before and after treatment, depth of treatment could be determined using a Acuson Sequioa 512 phase-array system in paired experiments.Results PpⅨ accumulation increased with increasing extracellular concentrations of ALA (0-1mmol/L). Adding 1mmol/L of CaNa2EDTA increased 30% PpⅨ accumulation over the same period of incubation in the concentration of 1mmol/L ALA. Significant difference was observed between the 5-ALA alone group and 5-ALA combined CaNa2 EDTA group in the PpⅨ accumulation (P<0.01). Cell viability after exposure to light decreased with adding CaNa2 EDTA, a statistical difference in a same fluence above 1.2 J/cm2 between two groups was demonstrated (P<0.05, P<0.01 respectively). Depth of treatment of skin cancers were increased in CaNa2 EDTA-treated group.conclusion CaNa2 EDTA could improve the PpⅨ accumulation and photosensitisation in HEp-2 cells. Clinically, CaNa2 EDTA could increase the depth of treatment in the cutaneous cancers.

    2015-01-01

    Full Text Available Hydrogen sulfide (H2S can be synthesized in mammalian cells by cystathionine γ-lyase (CSE and/or cystathionine β-synthase (CBS. Both CSE and CBS are expressed in rat gastric tissues but their role in human gastric neoplasia has been unclear. The aims of the present study were to detect CSE and CBS proteins in human gastric cancer and determine the effect of exogenous NaHS on the proliferation of gastric cancer cells. We found that both CSE and CBS proteins were expressed in human gastric cancer cells and upregulated in human gastric carcinoma mucosa compared with those in noncancerous gastric samples. NaHS induced apoptosis of gastric cancer cells by regulating apoptosis related proteins. Also, NaHS inhibited cancer cell migration and invasion. An antigastric cancer role of H2S is thus indicated.

    Full Text Available O momento nazista permanece um enigma impensado de que a cultura contemporânea continua cativa. O autor levanta a hipótese de que a persistência desse enigma e seus estragos duráveis se devem à insistência dos pensamentos político, sociológico e filosófico em construírem o nazismo à luz da metáfora hobbesiana do Leviatã. Propõe retomar a questão do nazismo sob a perspectiva do Behemoth, antônimo do Leviatã. Para tanto, sugere a necessidade de retornar a Freud e à psicanálise, balizas de um possível novo pensamento do político que escrutine a destrutividade nazista. Propõe ainda sondar as homologias entre nazismo, corjas e máfias, com base na figura da " heroicização da violência" que lhes seria comum. E avança um modelo " econômico" : a quimera, suscetível de capturar o caráter heterotópico e heterocrônico de sua construção criminosa.The paths of Behemoth. The Nazi moment remains as the thoughtless enigma of which contemporary culture is still captive. The author raises the hypothesis where the persistency of this enigma and its durable damages are due to the insistence of the political, social and philosophical thoughts in building the Nazism at the view of the Hobbesian metaphor of Leviathan. It is here proposed to resume the Nazism matter under Behemoth's perspective, antonym to Leviathan. For such, it is suggested a necessity to look back at Freud and the psychoanalysis, structured by a possible new political thought which scrutinizes the destructivity of the Nazism. It is also here proposed to gaze at the homologies between Nazism, mafias and gangs, with a base in the figure of " violence as a heroically act" that are their common ground. The author also advances an economical model: the chimera susceptible to capture the heterotopic and heterochronic character of its criminal construction.

    Cancer cachexia is a wasting syndrome characterized by weight loss, anorexia, asthenia and anemia. The pathogenicity of this syndrome is multifactorial, due to a complex interaction of tumor and host factors. The signs and symptoms of cachexia are considered as the prognostic parameters in cancer patients. This review gives an emphasis on the various mechanisms involved in cachexia and an insight into head and neck cancer cachexia.

    Although cancer can on occasion be caused by infectious agents such as specific bacteria, parasites, and viruses, it is not generally considered a transmissible disease. In rare circumstances, however, direct communication from one host to another has been documented. The Tasmanian devil is now threatened with extinction in the wild because of a fatal transmissible cancer, devil facial tumor disease (DFTD). Another example is canine transmissible venereal tumor (CTVT or Sticker's sarcoma) in dogs. There is a vast difference in prognosis between these two conditions. DFTD is often fatal within 6 months, whereas most cases of CTVT are eventually rejected by the host dog, who then is conferred lifelong immunity. In man, only scattered case reports exist about such communicable cancers, most often in the setting of organ or hematopoietic stem cell transplants and cancers arising during pregnancy that are transmitted to the fetus. In about one third of cases, transplant recipients develop cancers from donor organs from individuals who were found to harbor malignancies after the transplantation. The fact that two thirds of the time cancer does not develop, along with the fact that cancer very rarely is transmitted from person to person, supports the notion that natural immunity prevents such cancers from taking hold in man. These observations might hold invaluable clues to the immunobiology and possible immunotherapy of cancer. PMID:21212437

    Full Text Available This study analyzes the meanings that men with intestinal stoma attribute to their colorectal cancer experience and its treatment. The medical anthropology framework, gender identity and the ethnographic methods were used. A total of 16 men from 40 to 79 years of age, residents in Ribeirão Preto and neighboring cities, SP, Brazil participated in the study. Data collection was carried out through participant observation and semi-structured interviews. Two groups of meanings were selected through inductive data analysis: acknowledging the severity of the disease and the distress of having cancer, and being submitted to surgery and suffering from a stoma. These meanings revealed the tension that develops between traditional patterns of masculinity and the new identities resulting from the experience. The understanding of these meanings from a cultural perspective favors nurse-patient communication and enables planning of care appropriate to these patients' needs.El estudio tuvo como objetivo analizar el significado que los hombres, con estoma intestinal, atribuyen a la experiencia de la enfermedad y al tratamiento de cáncer de colorectal.

A pesquisa envolveu sete mulheres residentes em bairro popular de São Paulo. Na coleta de dados, utilizou-se observação participante e entrevista com questões norteadoras. Os dados foram apresentados na forma de narrativa e posteriormente organizados nas categorias: Percebendo as transformações corporais; Convivendo com as mudanças no corpo; Sentimentos e sensações na vida sexual durante a gestação e imaginando o corpo e a sexualidade após a gestação. As mulheres referiram-se às transformações do corpo como desconfortos e expressaram a preocupação de que fossem definitivas. Expressaram o desejo de que, após o parto, o corpo volte a ser como era e que volte a sentir desejo sexual. O reconhecimento destes fatos constitui-se numa ferramenta primordial na adequação das práticas profissionais.

Ready, steady, start!   A Large Angle Veto detector (white) in place in the NA62 decay volume (blue). With components from almost all the detectors in place downstream of the decay point of the mother particles – the kaons – and of the KTAG detector that tags the kaons before they decay, NA62 is ready for its first technical run. This unique run will test all the equipment as well as the trigger and the data acquisition systems. “This year, we will have about five weeks of beam from the SPS before the long shutdown of all the CERN machines,” says Ferdinand Hahn, NA62 Technical Co-...

    Full Text Available Cancer cachexia is a frequent complication observed in patients with malignant tumors. Although several decades have passed since the first focus on the metabolic dysfunction's associated with cancer, few effective therapeutic interventions have been successfully introduced into the medical armamentarium. The present study thoroughly reviews the basic pathophysiology of cancer cachexia and the treatment options already investigated in that field. Experimental and clinical studies were evaluated individually in order to clarify the intricate alterations observed in tumor-bearing patients. The difficulties in introducing sound and effective nutritional support or metabolic manipulation to reverse cancer cachexia are outlined in this review.A caquexia é uma complicação freqüentemente observada em pacientes portadores de tumores malignos. Apesar de várias décadas transcorrerem desde a descrição inicial das disfunções metabólicas associadas ao câncer, poucas medidas terapêuticas foram induzidas com sucesso na prática médica. O presente estudo apresenta uma revisão detalhada da fisiopatologia básica da caquexia em câncer, e as opções terapêuticas desenvolvidas nesta área. Estudos experimentais, assim como clínicos, são avaliados individualmente para esclarecer as alterações complexas observadas em pacientes portadores de tumores. As dificuldades encontradas para introduzir manipulações metabólicas e terapias de suporte nutricional eficientes são discutidas nesta revisão.

    Full Text Available OBJECTIVES: The objective was to assess the stress levels of parents of children with cancer and to identify correlations among demographic data and anxiety levels. METHODS: A descriptive, cross-sectional study, conducted in two Brazilian institutions, with 101 parents of children with cancer. Through interviews, parents responded to two instruments: Pediatric Inventory for Parents - Brazilian version, which assesses stress levels, and State-Trait Anxiety Inventory, for the measurement of anxiety. The correlations between the instruments and the sociodemographic variables of the parents and children were evaluated using the Spearman correlation coefficient. RESULTS: Higher levels of stress and anxiety were seen by young parents, young children and with less time since diagnosis. The fear of death and the disease impact on the life of a child were the events considered the most stressful for the parents . CONCLUSIONS: In clinical practice, the nurse who can identify the occurrence of these symptoms becomes capable of planning nursing care that includes the family in decisions about the care. Moreover, she can provide support to help parents manage their stress levels and positively face the illness of their children.OBJETIVOS: El objetivo fue evaluar el nivel de estrés de los padres de niños con cáncer e identificar correlaciones entre los datos sociodemográficos y los niveles de ansiedad.

  1. Thyroid cancer

    International Nuclear Information System (INIS)

    Special place in oncology belongs to thyroid cancer as it is a cancer originating from hormonally active tissue. 90 % of endocrine neoplasia are represented by thyroid cancer. It is a relatively rare cancer and due to its heterogeneity it encompasses spectrum of therapeutic approaches with interdisciplinary management which includes various implications for prognosis and lethality. Generally, the prognosis for patients with differentiated thyroid cancer is good, a 10 years survival rate is at 85 %. Standard treatment includes surgical therapy, TSH suppressive therapy and ablation of the thyroid remnant with radioactive iodine. Patients with recurrent disease, disseminated disease present at the time of diagnosis, patients unsuitable for surgical treatment or for treatment with radioiodine still remain a therapeutic challenge. As there is no effective systematic treatment there is a hope for new therapy with multiple kinase inhibitors such as vandetanib, sorafenib, cabozantinib a lenvatinib which is based on promising results of several studies.

    International Nuclear Information System (INIS)

    There will be over 160,000 cases of lung cancer diagnosed in the US in 1991, and deaths from this disease account for a quarter of all cancer deaths in this country. The incidence of lung cancer has continued to increase, especially among women. With 31% of American men and 25% of American women identified in the 1985 census as cigarette smokers, it is likely that this trend will continue well into the next century. Unfortunately, the majority of patients present with locally advanced tumors or distant metastatic disease. Presently, most patients with lung cancer will receive radiation therapy either in an attempt to control inoperable or locally advanced disease, or for palliation of symptomatic intrathoracic or metastatic disease. Because of the poor prognosis of all patients excepting those with early stage resectable lesions, lung cancer is appropriately the subject of intense clinical investigation and controversy throughout the world

    The image shows the new rare Kaon decay experiment at CERN, called NA62. The NA62 experiment is 270 metres long and includes a 120-metre-long vacuum tank, shown here, housing several of the particle detectors. (Note: the experiment axis is a straight line, the curving of the tank is an optical effect of the photo.) Kaons are particles that decay into lighter elementary particles. The kaon decay processes are mostly well known, except for some very rare decay modes. For example, NA62 is investigating a rare decay predicted by the Standard Model in which a kaon decays into one pion and two neutrinos. This process occurs only once every 10 billion decays. The understanding of such ultra-rare decays are of great importance because they test the Standard Model in energy ranges not accessible by direct measurements. They are therefore complementary to the measurements at the LHC. ultra high definition on demand (photolab@cern.ch).

O que se considera como um comportamento criativo no senso comum é tão diferente do que compreendemos, na abordagem gestáltica, como criatividade? Estas são algumas das perguntas sobre as quais buscaremos transcorrer ao longo deste artigo. Partimos de simples perguntas, pois talvez um bom recurso para se “tratar” da criatividade seja a curiosidade. Para isto, iremos apresentar a contribuição de alguns autores que discorreram sobre o tema da criatividade em suas obras, iniciando por Kurt Goldstein e sua Teoria Organísmica, que consideramos o principal substrato teórico para se pensar a criatividade na Gestalt–terapia.

  6. Breast cancer

    International Nuclear Information System (INIS)

    More than 20-year follow-up of A-bomb survivors in Hiroshima and Nagasaki has a crucial role in determining the relationship of radiation to the occurrence of breast cancer. In 1967, Wanebo et al have first reported 27 cases of breast cancer during the period 1950-1966 among the Adult Health Study population of A-bomb survivors. Since then, follow-up surveys for breast cancer have been made using the Life Span Study (LSS) cohort, and the incidence of breast cancer has increased year by year; that is breast cancer was identified in 231 cases by the first LSS series (1950-1969), 360 cases by the second LSS series (1950-1974), 564 cases by the third LSS series (1950-1980), and 816 cases in the fourth LSS series (1950-1085). The third LSS series have revealed a high risk for radiation-induced breast cancer in women aged 10 or less at the time of exposure (ATE). Both relative and absolute risks are found to be decreased with increasing ages ATE. Based on the above-mentioned findings and other studies on persons exposed medical radiation, radiation-induced breast cancer is characterized by the following: (1) the incidence of breast cancer is linearly increased with increasing radiation doses; (2) both relative and absolute risks for breast cancer are high in younger persons ATE; (3) age distribution of breast cancer in proximally exposed A-bomb survivors is the same as that in both distally A-bomb survivors and non-exposed persons, and there is no difference in histology between the former and latter groups. Thus, immature mammary gland cells before the age of puberty are found to be most radiosensitive. (N.K.)

  8. β decay of 32Na

    International Nuclear Information System (INIS)

    The β-decay of 32Na has been studied using β-γ coincidences. New transitions and levels are tentatively placed in the level scheme of 32Mg from an analysis of γ-γ and β-γ-γ coincidences. The observation of the indirect feeding of the 2321 keV state in 32Mg removes some restrictions previously placed on the spin assignment for this state. No evidence of a state at 2117 keV in 32Mg is found. Previously unobserved weak transitions up to 5.4 MeV were recorded but could not be placed in the decay scheme of 32Na

  9. The NA62 trigger system

    International Nuclear Information System (INIS)

    The main aim of the NA62 experiment (NA62 Technical Design Report, 〈http://na62.web.cern.ch/NA62/Documents/TDFulldocv1.pdf〉 [1]) is to study ultra-rare Kaon decays. In order to select rare events over the overwhelming background, central systems with high-performance, high bandwidth, flexibility and configurability are necessary, that minimize dead time while maximizing data collection reliability. The NA62 experiment consists of 12 sub-detector systems and several trigger and control systems, for a total channel count of less than 100,000. The GigaTracKer (GTK) has the largest number of channels (54,000), and the Liquid Krypton (LKr) calorimeter shares with it the largest raw data rate (19 GB/s). The NA62 trigger system works with 3 trigger levels. The first trigger level is based on a hardware central trigger unit, so-called L0 Trigger Processor (L0TP), and Local Trigger Units (LTU), which are all located in the experimental cavern. Other two trigger levels are based on software, and done with a computer farm located on surface. The L0TP receives information from triggering sub-detectors asynchronously via Ethernet; it processes the information, and then transmits a final trigger decision synchronously to each sub-detector through the Trigger and Timing Control (TTC) system. The interface between L0TP and the TTC system, which is used for trigger and clock distribution, is provided by the Local Trigger Unit board (LTU). The LTU can work in two modes: global and stand-alone. In the global mode, the LTU provides an interface between L0TP and TTC system. In the stand-alone mode, the LTU can fully emulate L0TP and so provides an independent way for each sub-detector for testing or calibration purposes. In addition to the emulation functionality, a further functionality is implemented that allows to synchronize the clock of the LTU with the L0TP and the TTC system. For testing and debugging purposes, a Snap Shot Memory (SSM) interface is implemented, that can work

Although the use of external radiotherapy in ovarian cancer has been limited due to the pattern of metastatic spread of this cancer, the present data support the view that ovarian carcinomas are radiosensitive tumors. Investigations on the effects of new approaches, such as delivering radiation more specifically to intraperitoneal ovarian cancer cells, are warranted. (author). 24 refs.; 4 figs.; 2 tabs

In this study, of qualitative nature, guided by the phenomenology and based on the theoretical-methodological thinking of Martin Heidegger, it searched for hearing the being-woman-who-belongsto the-familiar-risk-group, with the aim at analyzing comprehensively her meanings of secondary prevention. Before empathic relation and reduction of presuppositions, there were interviewed thirteen women indicated by theirs clients familiars. The hermeneutics made possible the interpretative comprehension of the being-there, who showed facets of its existential dimension. Guided by the talking and fear, under the ambiguity domain, it does not recognize as being of possibilities. It lacks better comprehension to move itself to the de-cision by the secondary prevention. The construction of the concept of being and the sense revelation, can support the nurse' s assistance practice and favor the singular, integral and human care, that privileges the attentive hearing to the lived of the being-woman, in her existential movement of in-comprehensions and questions.

    Full Text Available O objetivo principal deste estudo foi avaliar os resultados da cirurgia isolada ou associada a radioterapia pré-operatória em pacientes portadores de adenocarcinoma do reto. Foram analisados retrospectivamente 96 pacientes submetidos a cirurgias curativas entre 1972 e 1993. A análise visou, principalmente, comparar as taxas de sobrevida global em cinco anos e de recidiva local. Quarenta e seis pacientes tratados por cirurgias isoladas tiveram taxas de sobrevida em cinco anos e de recidiva local de 51,7% e 26,9%, respectivamente, nos estádios II e III. Cinqüenta pacientes submeteram-se a radioterapia pré-operatória na dosagem de 4.500 cGy, em 25 sessões de 180 cGy, com taxas de sobrevi da em cinco anos e de recidiva local de 60,8% e 18,2%, respectivamente, nos estádios II e III. As diferenças entre os dois grupos terapêuticos não foram estatisticamente significativas. A análise multivariada demonstrou que o estadiamento da neoplasia, principalmente com relação à presença ou não de linfonodos regionais metastáticos, foi o fator prognóstico mais importante, independentemente do grupo terapêutico analisado. Baseados nos resultados apresentados, discutimos que a indicação da radioterapia em câncer do reto deve ser mais seletiva, com realização de cirurgia imediata em pacientes portadores de tumores retais móveis, mesmo infiltrativos na parede, irradiando no pós-operatório apenas os casos com maior risco de recidiva, de acordo com o resultado do exame anatomopatológico da peça cirúrgica. Pacientes portadores de tumores com mobilidade reduzida em relação às paredes pélvicas devem ser irradiados no pré-operatório com a finalidade de facilitação do ato cirúrgico e diminuição do risco de disseminação de células tumorais no intra-operatório e conseqüente diminuição das taxas de recidiva local.The main objective of this study was to evaluate the results of surgical treatment alone or associated to

    Epigenetic alterations, including aberrant DNA methylation, play an important role in human cancer development. Importantly, epigenetic alterations are reversible and can be targets for therapy or chemoprevention for various types of human cancers. A field for cancerization, or a field defect, is formed by the accumulation of genetic and/or epigenetic alterations in normal-appearing tissues and can correlate with risk of cancer development. Thus, a better understanding of epigenetic field cancerization may represent a useful translational opportunity for cancer risk assessment, including previous history and exposure to carcinogenic factors, and for cancer prevention. In this article, we summarize current knowledge regarding epigenetic field cancerization and its clinical implications in gastrointestinal cancers, including colorectal cancer, gastric cancer and esophageal cancer.

    2014-04-01

    Full Text Available A inegável atenção dada ao corpo na sociedade inspirou a construção deste trabalho, visto que os imperativos atuais são a beleza, a forma e o vigor. A velhice e a inexorabilidade da morte apresentam-se para este ideal como incômodos que devem ser afastados através de diversos hábitos "saudáveis" e “rejuvenescedores”, como a ginástica, os cosméticos, as vitaminas, procedimentos estético-cirúrgicos, entre outros. O modo de “ser velho”, então, passa a ser configurado não mais por estereótipos negativos, mas a partir de um ethos em que os idosos são apresentados como saudáveis, joviais, engajados, produtivos e autoconfiantes. São corpos que ultrapassam as marcas do tempo, atléticos, firmes e lisos. Logo, aqueles que não aderem a este ethos podem tornar-se desviantes, estranhos, velhos, ultrapassados e precisam, portanto, serem descartados ou escamoteados. Tendo em vista estas questões, o presente trabalho propõe-se a discutir sobre o tema velhice, corpo e sociedade, na tentativa de problematizar sobre os atuais modos de subjetivação e o envelhecimento na contemporaneidade.

  16. Solid state diffusion of NaCl into NaY zeolite studied by positron annihilation

    International Nuclear Information System (INIS)

    A series of samples, prepared from mechanical mixtures of NaCl with NaY zeolite and resulting in the dispersion of NaCl in NaY, was studied by position annihilation spectroscopy. We measured the positron lifetime spectroscopy as a function of the weight ratio of the NaCl-NaY zeolite heated at 500 degree C for 1 h, as a function of the heating temperature held for 1 h, and as a function of the heating duration at 500 degree C for NaCl/NaY (15%). All the lifetime spectra were resolved into five components, in which the third, fourth and fifth components are related to the positron annihilation in β cage, supercage and interface void respectively. The experimental results showed that position annihilation spectroscopy is sensitive to the change of the dispersion of NaCl in NaY zeolite

    Pancreatic cancer is a major cause of cancer-associated mortality, with a dismal overall prognosis that has remained virtually unchanged for many decades. Currently, prevention or early diagnosis at a curable stage is exceedingly difficult; patients rarely exhibit symptoms and tumours do not display sensitive and specific markers to aid detection. Pancreatic cancers also have few prevalent genetic mutations; the most commonly mutated genes are KRAS, CDKN2A (encoding p16), TP53 and SMAD4 - none of which are currently druggable. Indeed, therapeutic options are limited and progress in drug development is impeded because most pancreatic cancers are complex at the genomic, epigenetic and metabolic levels, with multiple activated pathways and crosstalk evident. Furthermore, the multilayered interplay between neoplastic and stromal cells in the tumour microenvironment challenges medical treatment. Fewer than 20% of patients have surgically resectable disease; however, neoadjuvant therapies might shift tumours towards resectability. Although newer drug combinations and multimodal regimens in this setting, as well as the adjuvant setting, appreciably extend survival, ∼80% of patients will relapse after surgery and ultimately die of their disease. Thus, consideration of quality of life and overall survival is important. In this Primer, we summarize the current understanding of the salient pathophysiological, molecular, translational and clinical aspects of this disease. In addition, we present an outline of potential future directions for pancreatic cancer research and patient management. PMID:27158978

    Squamous cell carcinoma of the penis represents approximately 0.5% of all cancers among men in the United States and other developed countries. Although rare, it is associated with significant disfigurement, and only half of the patients survive beyond 5 years. Proper evaluation of both the primary lesion and lymph nodes is critical, because nodal involvement is the most important factor of survival. The NCCN Clinical Practice Guidelines in Oncology for Penile Cancer provide recommendations on the diagnosis and management of this devastating disease based on evidence and expert consensus.

    Cancer is typically classified as a leading non-communicable disease; however, infectious agents, such as Helicobacter pylori (H. pylori), hepatitis B virus (HBV), hepatitis C virus (HCV) and human papilloma virus (HPV), contribute significantly to the pathogenesis of various cancers. Less developed countries, including countries of the North African (NA) region, endure the highest burden of infection-related cancers. The five most common infection-associated cancers in NA in order of incidence are bladder cancer, cervical cancer, liver cancer, stomach cancer, and nasopharyngeal carcinoma. This review aims to outline the epidemiologic pattern of infection-associated cancers in five NA countries (namely: Morocco, Algeria, Tunisia, Libya and Egypt) highlighting the similarities and differences across the region. The present study employed an initial literature review of peer-reviewed articles selected from PubMed, ScienceDirect and World Health Organization (WHO) databases based on key word searches without restriction on publication dates. Original research articles and reports written in French, as well as data from institutional reports and regional meeting abstracts were also included in this extensive review. Egypt, Libya, Tunisia, Algeria and Morocco were selected to be the focus of this review. PMID:27512409

Análises de aflatoxinas realizadas no Laboratório de Análises Micotoxicológicas (LAMIC da Universidade Fedaral de Santa Maria, entre os anos de 1986 e janeiro de 2000, em 15.600 amostras de alimentos destinados principalmente ao consumo animal, demonstram que no milho analisado, 41,9% das amostras estavam contaminadas por aflatoxinas. Em surtos de aflatoxicose no campo, uma das características mais marcantes é a má absorção que se manifesta como partículas de ração mal digeridas na excreta das aves. Também observa-se, em frangos e poedeiras que recebem AFL, extrema palidez das mucosas e pernas. Dietas deficientes em riboflavina ou colecalciferol (vit. D tornaram frangos sensíveis, nos índices de desenvolvimento corporal, a concentrações muito baixas de AFL. O efeito aflatoxina nos frangos é maior na fase inicial de crescimento, ou seja, quando as aves ingeriram aflatoxina nos primeiros 21 dias de vida, e quanto maior o nível de stress do lote, menor a quantidade de AFL para afetar negativamente seu desempenho, seja na produção de carne ou de ovos. As principais micotoxinas do grupo dos tricotecenos são: toxina T-2; deoxynivalenol (DON; diacetoxyscirpenol (DAS, todas produzidas através de diversas espécies de fungos do gênero Fusarium.

    International Nuclear Information System (INIS)

    A study of 23Na via the 22Ne(p,γ)23Na and 23Na(γ,γ)23Na reactions is presented. Only a limited number of resonances has been studied, selected on the basis of strong excitation of the lowest levels of which the spin was unknown. As a result the spins are now known of all levels of 23Na with excitation energies up to 7 MeV, except for a few high-spin states which are too weakly excited in the decay of the known 22Ne(p,γ) resonances. The mean lifetimes of the 23Na levels at 4.43 and 7.89 MeV were found to be 350±70 and 220±17 attoseconds (1 attosecond = 10-18 seconds) respectively. 97 refs.; 22 figs.; 12 tabs

    Trivalent lanthanide ions (Ln3+)-doped inorganic nanoparticles (NPs) as potential luminescent bioprobes have been attracting tremendous interest because of their unique upconversion (UC) and downconversion (DC) luminescence properties. NaScF4, as an important host material, has been rarely reported and its crystal structure remains unclear. Herein, based on the single crystal X-ray diffraction, the space group of NaScF4 crystals was determined to be P31 containing multiple sites of Sc3+ with crystallographic site symmetry of C1, which was verified by high-resolution photoluminescence spectroscopy of Eu3+ at low temperature (10 K). Furthermore, monodisperse and size-controllable NaScF4:Ln3+ NPs were synthesized via a facile thermal decomposition method. The biotinylated NaScF4:Er3+/Yb3+ NPs were demonstrated for their applications as a heterogeneous UC luminescence bioprobe to detect avidin with a detection limit of 180 pM. After bioconjugation with amino-terminal fragment (ATF) of urokinase plasminogen activator (uPA), NaScF4:Ln3+ NPs also exhibited specific recognition of cancer cells overexpressed with uPA receptor (uPAR, an important marker of tumor biology and metastasis), showing great potentials in tumor-targeted bioimaging.Trivalent lanthanide ions (Ln3+)-doped inorganic nanoparticles (NPs) as potential luminescent bioprobes have been attracting tremendous interest because of their unique upconversion (UC) and downconversion (DC) luminescence properties.

    realizado em Segóvia, em uma área de baixa densidade populacional na Espanha, com alta proporção de populações rurais e imigrantes, de 2008 a 2009. Utilizou-se a entrevista semi-estruturada para coleta de informações. Foram entrevistadas dez parteiras das 16 Zonas Básicas de Saúde. A análise da informação baseou-se nas propostas da Teoria Fundamentada. ANÁLISE DOS RESULTADOS: O acesso e utilização do Programa Preventivo de Câncer Cervical relacionam-se a mulheres atendidas pela parteira, as vivências das mulheres em relação os resultados do exame de citologia vaginal e sua percepção de risco de sofrer um câncer de colo uterino. A barreira percebida é a distância para comparecer à consulta com a parteira. Para as mulheres imigrantes há ainda a possibilidade de não dispor de carteira de saúde e desconhecer o programa. A exclusão social também está relacionada a barreiras de acesso e utilização. O principal facilitador identificado foi o aconselhamento dos médicos de família para participar do programa. CONCLUSÕES: As parteiras percebem desigualdades de acesso e utilização do Programa Preventivo de Câncer Cervical que se relacionam tanto com características individuais das mulheres como com o meio geográfico em que vivem e com a própria estrutura do Programa. Há situações de vulnerabilidade da eqüidade de grupos de mulheres pouco representadas em nível de inquéritos populacionais, como as imigrantes e as que moram em zonas rurais.OBJECTIVE: To analyze the discourses of primary care midwives on access to and utilization of the Cervical Cancer Prevention Program.

    The Vall d'Hebron multidisciplinary prostate cancer (PC) team reviews recent advances in the management of this neoplasm. Screening studies with long follow-up show a reduction in mortality, whereas active surveillance is emerging as a therapeutic approach of non-aggressive cancers. New markers increase the specificity of PSA and also allow targeting suspected aggressive cancers. Multiparametric magnetic resonance (mMRI) has emerged as the most effective method in the selection of patients for biopsy and also for local tumor staging. The paradigm of random prostatic biopsy is changing through the fusion techniques that allow guiding ultrasonography-driven biopsy of suspicious areas detected in mMRI. Radical prostatectomy (RP) and radiotherapy (RT) are curative treatments of localized PC and both have experienced significant technological improvements. RP is highly effective and the incorporation of robotic surgery is reducing morbidity. Modern RT allows the possibility of high tumor dose with minimal adjacent dose reducing its toxicity. Androgen deprivation therapy with LHRH analogues remains the treatment of choice for advanced PC, but should be limited to this indication. The loss of bone mass and adverse metabolic effects increases the frequency of fractures and cardiovascular morbimortality. After castration resistance in metastatic disease, new hormone-based drugs have demonstrated efficacy even after chemotherapy resistance. PMID:25727526

    Dramatično postignuće medicinske tehnologije transplantacije organa omogućilo je mnogim osobama oštećenih organa da nastave živjeti duljim životom. Prva uspješna transplantacija izvedena je u Bostonu 1954. godine, a pravi proboj transplantacije organa dogodio se tri desetljeća kasnije, nakon otkrića Ciklosporina A koji rješava probleme odbacivanja organa. Danas je moguće transplantirati većinu organa uključujući bubrege, srce, jetru, gušteraču, pluća, kožu i niz tkiva poput koštane srži i rož...

  15. Dependence of intracellular Na+ concentration on apical and basolateral membrane Na+ influx in frog skin

    International Nuclear Information System (INIS)

    An isotopic method was developed to measure the intracellular Na+ content of the transepithelial Na+ transport pool of frog skin. Isolated epithelia (no corium) were labeled with 24Na either asymmetrically, from apical (Aa) or basolateral (Ab) solutions, or symmetrically (Aab). Transport pool Na+ could be identified from the kinetics of washout of 24Na carried out in the presence of 1 mM ouabain, 100 microM amiloride, and 1 mM furosemide that served to trap cold Na+ and 24Na within the transport pool. In control epithelia, Aab averaged 64.1 neq/cm2 (13.9 mM), and maximal inhibition of apical membrane Na+ entry with 100 microM amiloride caused Aab to decrease to 24.3 neq/cm2 (5.3 mM). Ouabain caused Aab to increase markedly to 303 neq/cm2 in 30 min, whereas amiloride inhibition of apical membrane Na+ entry reduced markedly the rate of increase of Aab caused by ouabain. These data, in part, confirmed the existence of an important basolateral membrane permeability to Na+ that was measured in separate studies of the bidirectional 24Na fluxes at the basolateral membranes of the cells. Both sets of data were supportive of the idea that a significant Na+ recycling exists at the basolateral membranes of the cells that contributes to the Na+ load on the pump and Na+ recycling participates in the regulation of the Na+ concentration of the Na+ transport pool of these epithelial cells

    Diet has a significant impact on colorectal cancer and both dietary fiber and plant-derived compounds have been independently shown to be inversely related to colon cancer risk. Butyrate (NaB), one of the principal products of dietary fiber fermentation, induces differentiation of colon cancer cell lines by inhibiting histone deacetylases (HDACs). On the other hand, (−)-epicatechin (EC) and (−)-epigallocatechin gallate (EGCG), two abundant phenolic compounds of green tea, have been shown to exhibit antitumoral properties. In this study we used colon cancer cell lines to study the cellular and molecular events that take place during co-treatment with NaB, EC and EGCG. We found that (i) polyphenols EC and EGCG fail to induce differentiation of colon adenocarcinoma cell lines; (ii) polyphenols EC and EGCG reduce NaB-induced differentiation; (iii) the effect of the polyphenols is specific for NaB, since differentiation induced by other agents, such as trichostatin A (TSA), was unaltered upon EC and EGCG treatment, and (iv) is independent of the HDAC inhibitory activity of NaB. Also, (v) polyphenols partially reduce cellular NaB; and (vi) on a molecular level, reduction of cellular NaB uptake by polyphenols is achieved by impairing the capacity of NaB to relocalize its own transporter (monocarboxylate transporter 1, MCT1) in the plasma membrane. Our findings suggest that beneficial effects of NaB on colorectal cancer may be reduced by green tea phenolic supplementation. This valuable information should be of assistance in choosing a rational design for more effective diet-driven therapeutic interventions in the prevention or treatment of colorectal cancer.

    mutations as well as an extension of the C terminus only by a single alanine. The dependence of the mutational effects on the specific α isoform in which the mutation is introduced was furthermore studied. At the cellular level we have characterized the C-terminal extension mutants and other mutants......, addressing the question to what extent they cause a change of the intracellular Na+ and K+ concentrations ([Na+]i and [K+]i) in COS cells. C-terminal extension mutants generally showed dramatically reduced Na+ affinity without disturbance of K+ binding, as did other RDP mutants. No phosphorylation from ATP...... was observed for the +28 mutation of α2 despite a high expression level. A significant rise of [Na+]i and reduction of [K+]i was detected in cells expressing mutants with reduced Na+ affinity and did not require a concomitant reduction of the maximal catalytic turnover rate or expression level. Moreover, two...

    It is of great importance to identify new cancer genes from the data of large scale genome screenings of gene mutations in cancers. Considering the alternations of some essential functions are indispensable for oncogenesis, we define them as cancer functions and select, as their approximations, a group of detailed functions in GO (Gene Ontology) highly enriched with known cancer genes. To evaluate the efficiency of using cancer functions as features to identify cancer genes, we define, in the screened genes, the known protein kinase cancer genes as gold standard positives and the other kinase genes as gold standard negatives. The results show that cancer associated functions are more efficient in identifying cancer genes than the selection pressure feature. Furthermore, combining cancer functions with the number of non-silent mutations can generate more reliable positive predictions. Finally, with precision 0.42, we suggest a list of 46 kinase genes as candidate cancer genes which are annotated to cancer functions and carry at least 3 non-silent mutations.
