Objective: To report a case of a multiple paraganglioma with 5 concurrent locations and also describe a complication not found in the literature, spontaneous tumor bleeding. Introduction: The paragangliomas are mostly benign and more frequent in women. Can be multiple, and these are considered as the most likely source of familial origin (30%-35%). The multicentric lesions can occur at different life stages not being necessarily simultaneous, a fact that prevents image exam research to be conclusive for tumor presence or absence. In this way the examination of the family members of patients, specially young ones, diagnosed with multicentric tumors may lead to negative results which doesn’t meant that the disease can be developed at a later time period. Therefore routine examination is not justifiable when symptoms relative to tumor presence are not present. Case report: A female patient of 32 years old complaining of tinnitus and diagnosed with five paragangliomas (jugulo-timpanic, bilateral carotid body and bilateral brachiocephalic trunk) through imaging studies. She reported suffering relatives of paragangliomas. Conclusion: The paper reports a rare case and perhaps unique in the literature, multiple paraganglioma with five locations and discusses difficult choice of treatment and complications.

Introduction: One of the most common causes of hyperthyroidism is Graves’ disease. The malignant exophthalmos is a rare condition characterized by the loss of visual function that doesn’t adequately respond to various forms of treatment, requiring, in most cases, surgical correction. Objective: We report a case of conjunctival edema and protrusion of the eyeball in patients secondary to Graves’ disease, characterizing malignant ophthalmopathy and discuss their surgical treatment. Case Report: A 73-year-old male patient presenting bilateral conjunctive hyperaemia, decreased visual acuity, exophtalmos with progressive deterioration. Pulse therapy was performed without improvement and then underwent bilateral ethmoidectomy. Discussion: Late diagnosis is harmful due to the fact that malignant disease is extremely aggressive and fast, as reported in this case. Most often, the ophthalmopathy follows a relatively mild and self-limiting course, making a proper diagnosis difficult if the disease progresses. In extreme cases acute orbital decompression is indicated complementing appropriate medical treatment, which will allow herniation of orbital contents. Many orbital decompression techniques have been used in the treatment of Graves’ ophthalmopathy. The most common of these is the endoscopic sinus surgery which potentiated act in decompression of the medial wall safely and minimally invasive. In our case, open bilateral ethmoidectomy was used, due to the fact that surgeons are most experienced in this technique. Although the post-operative has been successfully submitted, no signs of recurrence were observed after fifteen days due to the evolution of Graves’ disease. Even with outpatient treatment, he walked to the total visual loss. Conclusion: We observed that the malignant ophthalmopathy is rare and aggressive;however, in spite of therapeutic resources used, it can progress to total visual loss.

After Enzyme Replacement Therapy (ERT) using recombinant human acid alpha-glucosidase (rhGAA), survival of Infantile Pompe Disease (IPD) patients through the first 18 months of age has been documented and acquisitions of motor development are an important outcome, but description of its course is scarce. Objective: To describe the motor development in an IPD patient and its correlation with clinical conditions during the first 18 months on ERT with rhGAA. Methods: By longitudinal observational study of an IPD case at early stage. Clinical and biochemical characteristics were obtained from patient records. Echocardiogram assessed cardiac indexes and the urinary biomarker—glucose tetrasaccharide (Glc4)—was obtained by HPLC/UV, following sample derivatization with butyl 4-amino benzoate and analysis on a C18 stationary phase column. Motor skills were evaluated with Alberta Infant of Motor Scale (AIMS) and motor delay was considered as motor percentile (p) below 10. Descriptive statistical analysis was carried out and t-test was used to calculate the differences among means, with significance level defined as p value < 0.05. Results: After ERT beginning amelioration of the cardiomyopathy with reduced left ventricle mass index (LVMI) from the 2nd month onwards was observed, but above the upper normal limit for healthy children and CRIM-positive IPD patients. Although GAA antibodies level remained above the recommended titers and fluctuating elevation of Glc4 quantified, motor development analysis showed an ascendant curve expected for age within achievement of independent ambulation. Motor delay after pneumonia and maintenance of hypotonia were noted. Variation of Glc4 appeared long after a transitory intercurrence. Conclusion: In an IPD case, motor development can have normal evolution despite hypotonia. Motor analysis seems to be sensitive to follow-up clinical intercurrences. To elucidate the interaction among prognostic factors and outcomes, further clinical studies

Liposarcomas (LS) are the second most common type of soft tissue malignancies in adults;they arise from mesenchymal cells and account for 1% of all adult cancers and 15% of all pediatric cancers. The site of origin can be from anywhere there is fat in the human body. LS are classified based on the primary site of origin, and mediastinal LS are extremely rare. When mediastinal neoplasms are stratified based on histology, they represent less than 1% of all mediastinal tumors. To date, less than 150 cases have been reported in the English literature. This article aims to present an unusual case of an extremely rare malignancy and perform a systematic review of the latest literature. In this report, our group is documenting the presentation, management, and outcome of a 65-year-old male patient with a massive anterior mediastinal primary LS. The tumor was displacing the mediastinum into the right chest, occupying most of the left chest, and pushing the diaphragm into the abdomen. Mediastinal liposarcomas are extremely rare malignancies and can prove to be challenging to diagnose and treat. Aggressive surgical treatment with R0 resection is the gold standard, however, tumor biology in many cases is associated with variable growth rates and encroachment of adjacent vital structures and blood vessels. When complex anatomical structures preclude an R0 resection, there is a high incidence of local recurrence. In cases where there is a high risk of recurrence, radiotherapy is indicated and chemotherapy has a more limited role.

<i>In Vitro</i>Priming of Sugarcane Varieties (RB966928 and RB867515)

引用

American Journal of Plant Sciences 2018年第4期9卷 763-774页

Sugarcane, as a glycophyte, shows sensitivity to saline soils at various stages of its growth. The aim of this study was to evaluate the in vitro priming response in two sugarcane varieties (RB966928 and RB867515). Micropropagated plants, from meristems, received priming treatments by adding the salts (NaCl and KCl) in different concentrations (0.0;12.5;25.0 and 50.0 mM), in the MS medium. Subsequently, the plants were cultivated in rooting medium without addition of salts, acclimatized and submitted to gradient ex vitro saline stress with 20 → 40 and 60 mM, of each salt, for 30 days. The analyzed variables were dry matter of shoot and root, number of tillers and estimation of chlorophyll content. The experiment was carried out in a 2 × 2 × 4 factorial arrangement, in a completely randomized experimental design. Twenty replicates were used throughout the experiment. Data were submitted to analysis of variance and regression and the means were compared by Tukey’s test, at a 5% probability level. The priming treatments presented a significant effect, with triple interaction, in the chlorophyll index. In the treatment with NaCl, the variety RB966928 showed an increase in the chlorophyll index with the increase of treatment levels, up to an optimal limit of 31.47 mM. On the other hand, the variety RB867515 showed decreasing in chlorophyll index. In contrast, in KCl treatment, the variety RB867515 presented the increase at the chlorophyll index with the maximum point of 25 mM. For the variables, shoot dry matter (SDM) and root dry matter (RDM) there was a significant difference (p 0.05 and p 0.01, respectively) only between the varieties. The variety RB966928 presented higher SDM and RDM in relation to the variety RB867515. Studies are recommended with increasing the duration of the priming treatments and more detailed study of the culture throughout its productive cycle.

The DArk Matter Particle Explorer（DAMPE）,also known as Wukong in China,which was launched on 2015 December 17,is a new high energy cosmic ray and γ-ray satellite-borne *** of the main scientific goals of DAMPE is to observe Ge V-Te V high energy γ-rays with accurate energy,angular and time resolution,to indirectly search for dark matter particles and for the study of high energy astrophysics. Due to the comparatively higher fluxes of charged cosmic rays with respect to γ-rays,it is challenging to identify γ-rays with sufficiently high efficiency,minimizing the amount of charged cosmic ray contamination. In this work we present a method to identify γ-rays in DAMPE data based on Monte Carlo simulations,using the powerful electromagnetic/hadronic shower discrimination provided by the calorimeter and the veto detection of charged particles provided by the plastic scintillation detector. Monte Carlo simulations show that after this selection the number of electrons and protons that contaminate the selected γ-ray events at～10 Ge V amounts to less than 1% of the selected ***,we use flight data to verify the effectiveness of the method by highlighting known γ-ray sources in the sky and by reconstructing preliminary light curves of the Geminga pulsar.

Cationic peptide with the sequence INKKI 41-45 was isolated from bovine β-casein after tryptic hydrolysis and synthetized. The aim of this work was to evaluate the antiproliferative activity in vitro and antitumor effect in animal model. The in vitro cytotoxicity was evaluated on B16F10 melanoma cells by MTT assay. Detection of apoptosis was measured using the annexin V/PI double staining and cell cycle analysis performed flow cytometry. Caspase-3 activity was analyzed with substrate specific fluorogenic DEVD-MCA. In vivo, antitumor activity was evaluated in B16F10 melanoma tumor-bearing C57BL/6J mice. The animals were treated with 55 mg/kg INKKI administered into peritumoral region, while control group received saline solution. The following antitumor parameters were examined: tumor volume, number of metastases, tumor delayed time, tumor doubling time. Histological analyses were performed with H & E staining. The results showed that INKKI induced dose-response cytotoxicity selective for B16F10 melanoma cells (IC50 1.7 μM) and did not present cytotoxic effects for FN1 fibroblast cells. INKKI-induced apoptosis detected trough of annexin V/PI assay and it was accompanied with an increase of sub-G1 apoptotic fractions and significant increase of caspase-3 cleavage. The tumor-bearing mice treated with INKKI showed a significant reduction in tumor volume of 72.62% and decreased of metastasis number loci. In addition, INKKI caused a significant delay in tumor growth and prolonged the tumor doubling time. Histological analysis revealed an increased of necrosis areas and reduction of tumor cells in tumor treated with INKKI, it was a many hallmark of its antitumor effects observed from in vivo experiments. In conclusion, we show that INKKI is a peptide that could be considered a new putative candidate development to anticancer therapy drug.
