Giant Cystic and Mediastinal Parathyroid Adenoma with Non-Uptake in Scintigraphy

引用

Journal of Cancer Therapy 2018年第11期9卷 850-856页

作者： Raquel alfonso-Ballester Ana Izquierdo Moreno Rosa Martí fernández Nicolás Tarigo Norberto Cassinello fernández Joaquin Ortega Serrano Department of Surgery Clinic University Hospital of Valencia Valencia Spain General Surgery Department Clinic Hospital Faculty of Medicine Republic University Montevideo Uruguay

Introduction: In 85% of patients, the cause of Primary Hyperparathyroidism (PHPT) is an adenoma. Parathyroid adenoma localization is usually simple. 96% of localizations prior to surgery are achieved with ultrasound and scintigraphy combination. Difficulties can appear. If the gland is not located in a cervical position and has no uptake in scintigraphy but there is high suspition of an adenoma causing the PHPT, some extra tests should be considered. Case Report: We present a case of giant cystic mediastinal adenoma, a quite rare condition, which was diagnosed as a thyroid colloid cyst by ultrasound, and was not localized by scintigraphy. We report the CT scan and the magnetic resonance imaging (MRI) images that show the tumour. It was surgically resected by a cervical approach. After the excision, the patient recovered normal levels of Calcium and Parathormone (PTH). Conclusion: We review literature about cystic and mediastinal adenomas and diagnostic methods when the standard ones do not give an accurate localization diagnosis.

Step-by-Step Building of a Four Dimensional Fatigue Compatible Regression Model including Frequencies

The purpose of this research is to develop a model, with emphasis on compatibility conditions and model building, valid for high cycle fatigue design components such as wind turbines, automobiles, high speed railways and aeronautical material. In this work, we have added the frequency as one more variable to an existing fatigue model that already includes maximum stress, stress ratio and lifetime. As a result, a model and estimation method has been proposed and a random variable V has been identified, which, allows the accumulated damage and the probability of failure to be assessed for any load history in terms of stress levels, stress ranges and frequencies. Finally, the model is validated using a large set of real experimental data.

Thyroid Metastases from Clear Cell Renal Carcinoma: Presentation of an Unusual Case and Literature Review

引用

Journal of Cancer Therapy 2017年第11期8卷 941-947页

作者： Rafael Cholvi Calduch Raquel alfonso-Ballester Clara Alfaro-Cervelló Norberto Cassinello fernández Joaquín Ortega Serrano Departments of Surgery Clinic University Hospital of Valencia Valencia Spain Departments of Pathology Clinic University Hospital of Valencia Valencia Spain

Clear cell type renal cell carcinoma is a malignant tumor that can metastasize to many locations, but unusually spreads to thyroid. Therefore it is important to know the oncological background of the patient and to perform a complete immunohistochemical analysis of the thyroid lesion to obtain a correct diagnosis. Thyroidectomy can be considered in patients with no other metastasis or in those who present compressive symptoms as a palliative measure. We expose the case of a patient with clear cell type renal cell carcinoma, with a previously known bone metastasis of renal origin and symptomatic goiter containing a nodule that was found to be a metastasic lesion.

Dominant Macroalgae in Bahía de Cochinos, Matanzas, Cuba

Spatial-temporal variations of macroalgae were analyzed in a study conducted in Cueva de Los Peces (CP) and Punta Perdiz (PP), two dive sites located on the eastern coast of Bahía de Cochinos. The most conspicuous species found from 3 to 20 m depths were present in the biotopes of ridges and shallow and deep terraces. Sampling was carried out in September 2014, and March and October 2016 by autonomous diving and direct methods. Qualitative visual censuses and quantitative analyzes were used to estimate the coverage (%) of the genera according to the AGRRA methodology with the use of the 10 m linear transect and quadrats as the sampling unit. The first list of macroalgae for the area is offered that includes 49 taxa of which 10 were Rhodophyta, 10 Ochrophyta (Phaeophyceae), and 29 Chlorophyta. The dominant genera during the study period were Halimeda, Dictyota, Lobophora, and Udotea. Spatial differences were found regarding the specific composition. Temporal variations were evidenced in terms of the relative abundance of the genera present, which reveals temporal changes in the qualitative structure, where some species replace others. The information obtained is pioneering and can serve as a comparative baseline for future monitoring of the area.

Anaerobic Biotransformation of Nitro-Compounds to Amines by Bovine Rumen Fluid

引用

Green and Sustainable Chemistry 2011年第3期1卷 47-53页

作者： alfonso Rodríguez Ignacio Irazoqui Guzmán álvarez Cecilia Cajarville José Luis Repetto Mercedes gonzález Hugo Cerecetto 不详

Microorganims of the bovine rumen fluid biocatalyzed the reduction of nitro-compound substrates to yield the respective amines. This enzymatic process, using ruminal contents, has rarely been reported in associa- tion with the bioreduction of nitro groups. The biotransformation reactions catalyzed by this system were de- pendent of both the electronic characteristics and the area/volume of the nitro-substrates confirming the processes are enzymatic. The semi-preparative scale biotransformation went by in good yield showing the rumen fluid may be employed in the synthesis of amines under very mild conditions and, moreover, it may have application in the bioremediation of nitro-compounds.
