Revista Cubana de Estomatolog?-a , 2011,
Abstract: clear cell odontogenic carcinoma is a rare malignant odontogenic neoplasm, with a predilection for the anterior segment of the jaws, and presenting basically in women between the fifth and seventh decades of life. ccoc is composed histopathologycally by strands or groups of cells showing clear cytoplasm associated with cells showing eosinophilic cytoplasm and some times with tall columnar cells that resambled ameloblasts. ccoc is considered a low-grade malignancy but in some cases its behavior is aggressive giving local and distant metastasis, so the recommended treatment is a radical resection and follows the patient very close. ccoc should be diferenciated microscopically from other local and metastatic lesions that are composed with clear cells also, in order to render a proper diagnosis and treatment. we are presenting a clinical case corresponding to a 69 years old female patient, with a 10 year history of a slow growing anterior mandibular lesion without lymph node or distant metastasis, with a biopsy diagnosis of clear cell odontogenic carcinoma, the patient was treated by partial resection of the anterior mandible and reconstructed with a titanium plate.
Carcinoma odontogénico de células claras Odontogenic carcinoma of clear cells

Revista Cubana de Estomatolog?-a , 2011,
Abstract: El carcinoma odontogénico de células claras es un raro tumor odontogénico que se presenta principalmente en la parte anterior de la mandíbula, mayormente en mujeres entre la quinta y séptima década de vida. Se caracteriza histológicamente por redes de células con citoplasma claro mezcladas con células que contienen citoplasma eosinófilo. Es sumamente agresivo y puede presentar metástasis local o a distancia. Al emplearse el tratamiento por enucleación y curetaje, frecuentemente da lugar a recurrencia, por lo que se aconseja el tratamiento radical de resección mandibular hasta una zona libre de lesión. El carcinoma odontogénico de células claras debe ser considerado en el diagnóstico diferencial de tumores mandibulares que presenten células claras para el establecimiento del plan de tratamiento adecuado. Se debe incluir el seguimiento a largo plazo del paciente. Se presenta el caso de un paciente femenino de 69 a os de edad, con una lesión presente en la región presinfisaria derecha, sin afectación de ganglios linfáticos regionales o metástasis aparente. Se efectuó osteotomía segmentaria mandibular y reconstrucción con placa de titanio.

Abstract:
Mycoplasma mycoides subsp. capri is the causative agent of severe and acute respiratory problems in goats, which spreads rapidly and represents high mortality. The serological profile of the goat population, from nine regions in seven states of Mexico, was screened by the Complement Fixation test (CF) in sera from asymptomatic goats and animals with mild respiratory symptoms. Sera and nasal swabs of 827 goats were collected for the isolation of the organism. An antiserum was prepared against a previously isolated field strain of Mycoplasma mycoides subsp. capri. CF Antibody titers were associated with the results of the isolates to determine the cutoff point. The CF was considered as positive if its result was ≥1/16. The CF registered 251 positive goats (30.35%) and 576 (69.65%) negative; the test showed high sensitivity (93.33%) and specificity (72.27%). In the specific case of diagnosis for mycoplasmosis associated with respiratory problems in goats, the CF proved to be a good diagnosis test, this study determined that 30% of the goat population showed antibody titers against Mycoplasma mycoides subsp. capri and revealed those animals who have had contact with this microorganism during their lives regardless of the presence or absence of respiratory symptoms.
CENTROS HISTóRICOS LATINOAMERICANOS: TENDIENDO PUENTES ENTRE EL PATRIMONIO Y LA CIUDAD
José Carlos Hayakawa Casas
Quivera , 2008,
Abstract: El patrimonio cultural constituye un espectro esencial y dinámico de la actividad humana. Así, los centros históricos representan comunidades privilegiadas tanto cuantitativa como cualitativamente. La adecuada gestión de dicho patrimonio puede devenir en incremento de la calidad de vida de dichas comunidades. él análisis de casos de gestión del patrimonio cultural experimentados en centros históricos latinoamericanos que configuraron dicho patrimonio en factor de desarrollo sostenible aporta a desarrollar una panorámica y a sistematizar las "lecciones aprendidas".

The solar rotation in the period 1853-1870 from the sunspot catalogues of Carrington, Peters, and de la Rue
Ricard Casas,José M. Vaquero
Physics , 2014, DOI: 10.1007/s11207-015-0756-2
Abstract: R. C. Carrington, C. H. F. Peters, and W. de la Rue observed the sunspots in the second half of the 19th century, determining their heliographic positions between 1853 and 1870, before the establishment of the solar program of the Royal Greenwich Observatory. The large tables of sunspot positions included in the catalogues published by these observers have recently been converted to a machine readable format. The present work analyses this data by calculating the sunspot group velocities for each observer. These results are then fitted with a differential rotation law to compare the data of the three observers with each other and with the results published by other authors. Finally, a study is made of the possible relationship between the sunspot group areas as determined by de la Rue and the corresponding sunspot group velocities.

Landscape management and domestication of Stenocereus pruinosus (Cactaceae) in the Tehuacán Valley: human guided selection and gene flow
Parra Fabiola,Blancas José,Casas Alejandro
Journal of Ethnobiology and Ethnomedicine , 2012, DOI: 10.1186/1746-4269-8-32
Abstract: Background Use of plant resources and ecosystems practiced by indigenous peoples of Mesoamerica commonly involves domestication of plant populations and landscapes. Our study analyzed interactions of coexisting wild and managed populations of the pitaya Stenocereus pruinosus, a columnar cactus used for its edible fruit occurring in natural forests, silviculturally managed in milpa agroforestry systems, and agriculturally managed in homegardens of the Tehuacán Valley, Mexico. We aimed at analyzing criteria of artificial selection and their consequences on phenotypic diversity and differentiation, as well as documenting management of propagules at landscape level and their possible contribution to gene flow among populations. Methods Semi-structured interviews were conducted to 83 households of the region to document perception of variation, criteria of artificial selection, and patterns of moving propagules among wild and managed populations. Morphological variation of trees from nine wild, silviculturally and agriculturally managed populations was analyzed for 37 characters through univariate and multivariate statistical methods. In addition, indexes of morphological diversity (MD) per population and phenotypic differentiation (PD) among populations were calculated using character states and frequencies. Results People recognized 15 pitaya varieties based on their pulp color, fruit size, form, flavor, and thorniness. On average, in wild populations we recorded one variety per population, in silviculturally managed populations 1.58 ± 0.77 varieties per parcel, and in agriculturally managed populations 2.19 ± 1.12 varieties per homegarden. Farmers select in favor of sweet flavor (71% of households interviewed) and pulp color (46%) mainly red, orange and yellow. Artificial selection is practiced in homegardens and 65% of people interviewed also do it in agroforestry systems. People obtain fruit and branches from different population types and move propagules from one another. Multivariate analyses showed morphological differentiation of wild and agriculturally managed populations, mainly due to differences in reproductive characters; however, the phenotypic differentiation indexes were relatively low among all populations studied. Morphological diversity of S. pruinosus (average MD = 0.600) is higher than in other columnar cacti species previously analyzed. Conclusions Artificial selection in favor of high quality fruit promotes morphological variation and divergence because of the continual replacement of plant material propagated and introductio
