An Example of S-Kernel and its Properties in Potential Theory (A. NATURAL SCIENCE)
In potential theory we consider ℑm-kernels Φ_m constructed by locally fundamental solutions E_m of a differential equation ℑ_m u=0,ℑ_m=[numerical formula] (m≩1), in the n-dimensional Euclidean space R^n. We shall show such a kernel to be an S-kernel, and investgate its properties, so called ℑ_m-potentials with respect to ℑ_m-kernels and the relationship between ℑ_m-potentials and non-negative massdistributions on the relatively compact open set Ω of R^n

On Properties of Integral Kernel Functions in Axiomatic Potential Theory (A. NATURAL SCIENCE)
On the Bauer harmonic space with certain conditions in the axiomatic potential theory, we construct an integral kernel k (x, θ) and investigate properties of k (x, θ). Furthermore we show an example of k (x, θ) on one-dimentional Euclidean space R^1 in the last paragraph
On the Regularity of Minimal Boundary Points in the Harmonic Space (A. NATURAL SCIENCE)
In this paper we establish the existence of an ideal boundary Δ for X such that the points of Δ correspond to non-negative harmonic functions, Δ supports the maximal representing measures for positive bounded (and quasibounded) harmonic functions, and almost all points of Δ are regular for the Dirichlet problem
Prevalência de síndrome metabólica em pacientes curados de câncer pediátrico
O câncer atinge cerca de doze mil crianças por ano no Brasil. Parte delas, quando submetida a tratamento, tende a possuir maiores chances de desenvolver Síndrome Metabólica. Introdução: As crianças e adolescentes tratadas de câncer tendem a desenvolver a síndrome metabólica devido a alterações que os radioterápicos e quimioterápicos propiciam. Essas disfunções acometem os tecidos: adiposo, osteomuscular, endotelial; o trato gastrointestinal e o fígado. Objetivos: Analisar a prevalência de síndrome metabólica em crianças curadas de câncer e comparar as variáveis estudadas. Materiais e Métodos: Avaliamos trinta e oito pacientes do Hospital GPACI que tenham terminado o tratamento de câncer há, no mínimo, cinco anos. Foram investigadas variáveis como: glicemia, pressão arterial, circunferência abdominal, HDL, triglicerídeos, tipo de câncer, tipo de tratamento e histórico familiar. Como grupo controle, utilizamos 20 irmãos dos pacientes analisados sob os mesmos parâmetros. Resultados: Sobreviventes tiveram maior chance de desenvolver síndrome metabólica (RR 2,1 Mid-p 0,27). Tanto no grupo controle quanto no grupo de curados, o HDL foi o índice que teve mais alterações, estando abaixo ou igual a 45mg/dL em 46% dos voluntários. Comparando o grupo estudado com o grupo controle, a circunferência abdominal foi o fator de maior relevância (RR 5,2 Mid-p 0,02). Discussão: Contrastamos a prevalência de síndrome metabólica encontrada nos curados de câncer tanto com seus irmãos quanto com crianças e adolescentes dos Estados Unidos da América. Em ambas as comparações, a prevalência no grupo estudado foi maior, o que é semelhante a outras pesquisas realizadas. Conclusão: A circunferência abdominal foi o fator que apresentou significância estatística e maior risco de acometer os sobreviventes de câncer infantil. Diferentemente de outros estudos, os outros índices não tiveram significância estatística, provavelmente pelo tamanho da amostra.In Brazil, cancer affects around twelve thousand children per year. Many of them when submitted to a treatment have increased chances to develop metabolic syndrome when compared to another child. Introduction: Adolescents and children treated of cancer are propitious to develop metabolic syndrome due to changes that radiotherapy and chemotherapy provides. These dysfunctions compromise fat tissue, muscle, skeletal, endothelium tissue, gastrointestinal tract and the liver. Objectives: Evaluate the prevalence of metabolic syndrome in children treated of cancer and compare with parameters investigated. Materials and methods: Thirty-eight patients of GPACI Hospital that had finished cancer treatment in five years at least were analyzed. It was considered variations such as: plasma glucose, blood pressure, waist circumference, HDL, triglycerides, cancer type, treatment type and familiar historical. As control group, we used 20 siblings of the analyzed patients under the same parameters. Results: Survivors had increased risk to develop metabolic syndrome (RR 2,11 Mid-p 0,27). HDL was the index with most alterations in control group and in the studied group (less or equal 45mg/dLin 46% of volunteers). Comparing the studied group with the control group, the waist circumference was the most important factor (RR 5,2 Mid-p 0,02). Discussion: As seen in other reports, the prevalence of metabolic syndrome in the group survivors of pediatric cancer was superior to the control group and also higher than the prevalence of metabolic syndrome in children and adolescents of USA. Conclusion: Waist circumference was statiscally significant with a RR 5,2 (mid-p 0,02). Differently from other studies, the other factors were not relevant, probably because the sample size

A woman in her 60s who was diagnosed as having hypercalcemia and hyperparathyroidism was referred to our hospital. Serum calcium and intact parathyroid hormone levels were11.4mg/ ml and 107 pg/ml, respectively. Chest computed tomography revealed an enhanced mass measuring approximately1.5cm located in the anterior mediastinum. 99mTc-Methoxy-isobutylisonitrile scintigraphy demonstrated an anterior mediastinal mass. These findings suggested an ectopic parathyroid tumor located in the mediastinum. The patient underwent resection of the parathyroid tumor with video-assisted thoracic surgery(VATS). The operation time was 114 min. The postoperative day1(POD1)calcium level rapidly decreased to8.3mg/ml. The patient was discharged on POD5, and there have been no signs of recurrence 1 year after the surgery. Parathyroidectomy by VATS for ectopic mediastinal parathyroid tumors is advantageous because it is less invasive and more cosmetic. VATS may be used as a standard approach for ectopic mediastinal parathyroid tumors. We report the surgical treatment of a case of ectopic mediastinal parathyroid adenoma using video-assisted thoracoscope

Two-hundred thirty-six patients with primary thyroid cancer who received operation were divided into two groups by age, i.e.,59patients of age <45years(Early adulthood, EA)and177 patients of age≧45years(advanced age, AA). Clinicopathologic factors and disease-free survival (DFS)were compared between the two groups. There was no difference in clinicopathologic factors except for higher proportion of patients with poorly differentiated adenocarcinoma in the AA patients than in the EA patients(6.7% vs. 0%, p=0.041). DFS was significantly longer in the AA patients than in the EA patients(disease-free rates at10years after operation,94.8% vs. 72.5%, p=0.0031). Overall survival was not different between the two groups. The EA patients who showed shorten DFS were divided into two groups,17 patients of age <30 years (juvenile and young adult, JYA)and 42 patients of age ≧30 years, and DFS of each group was compared with that of the AA patients. Although disease-free survival rates at 10 years of the JYA patients were not different(92.6% vs.94.8%, p=0.125), those of patients of age ≧30years were significantly lower than those of the AA patients(70.0% vs. 94.8%, p=0.0021). These findings suggest that patients with primary thyroid cancer who are ≧30 years old in the young adulthood should be observed carefully after operation for early detection of relapse
Three dimensional optical manipulation and structural imaging of soft materials by use of laser tweezers and multimodal nonlinear microscopy
We develop an integrated system of holographic optical trapping and
multimodal nonlinear microscopy and perform simultaneous three-dimensional
optical manipulation and non-invasive structural imaging of composite
soft-matter systems. We combine different nonlinear microscopy techniques such
as coherent anti-Stokes Raman scattering, multi-photon excitation fluorescence
and multi-harmonic generation, and use them for visualization of long-range
molecular order in soft materials by means of their polarized excitation and
detection. The combined system enables us to accomplish both, manipulation in
composite soft materials such as colloidal inclusions in liquid crystals as
well as imaging of each separate constituents of the composite material in
different nonlinear optical modalities. We also demonstrate optical generation
and control of topological defects and simultaneous reconstruction of their
three-dimensional long-range molecular orientational patterns from the
nonlinear optical images
