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.

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: Head and neck cancer (HNCC) is the sixth most common cancer with an incidence of approximately 600,000 cases per year and 300,000 annual deaths worldwide1y2. In Cuba, cancer of the larynx is the fourth cause in incidence, being the fourth cause of cancer death in men. Radiotherapy constitutes an important modality in the control of these tumors and the Intensity Modulated Radiotherapy (IMRT) is a new advance in this field. With it, it is possible to improve dose distribution, decreasing the dose in adjacent healthy tissues and escalating dose in tumor. In this work we present 33 patients of National Institute of Oncology and Radiobiology in Cuba (INOR), in whom the IMRT was used as a treatment technique with a hypofractionation of the dose. Their response was observed at the end of the treatment and one month later. 56% (19) of the patients had a complete response to treatment at the primary site of the tumor and neck. 10% (3) had no response, progressed. 11 of the patients had no response at the lymph node site at the end of treatment, 8 of these 11 had complete remission one month after radiotherapy ended.

Abstract: with the objective of estimating allele frequencies, and testing for population divergence for the csn1s1 locus, genotypes of animals from five goat populations; saanen (n = 97), alpine (n = 81) toggenburg (n = 92), local goats with external appearance similar to the murciana-granadina breed from central mexico (n = 26) and heterogeneous local animals denominated mosaico lagunero (n = 30), from northern mexico, were identified using pcr and xmn1 pcr-rflp methodology. for saanen, alpine and toggenburg, the sum of e and f alleles had the largest frequencies (from 0.468 to 0.789), while for the groups local murciana-granadina and mosaico lagunero the sum of the most frequent allelic groups (a* and b*), were 0.385 and 0.533 respectively. both local murciana-granadina and mosaico lagunero populations showed heterozygote excess (p < 0.08). the percentage of the total genetic variation (fst) explained by population differences was 5.16. there was genetic differentiation for most pair comparisons between populations (p < 0.05), excepting for alpine versus toggenburg, and toggenburg versus mosaico lagunero (p > 0.05). for saanen and alpine the frequencies of alleles e and f were similar to the same breeds previously analyzed in europe. therefore there are opportunities of increasing the frequency of the strong alleles for protein content gene assisted selection (gas) in these two breeds. for toggenburg the most frequent allelic groups were f (0.32) and b* (0.21). results indicate differentiation between most populations for this locus. moreover, heterozygote excess in local populations indicated breed admixture.

Abstract: Coffee is one of the most consumed and commercialized crops in the world, which is why there is a potential risk to find arabica coffee (an expensive variety) adulterated with robusta coffee (a cheaper variety). The currently used technique for certifying coffee, High Performance Liquid Chromatography (HPLC), requires the sample to be subjected to a chemical treatment prior to analysis; in addition, the equipment is bulky and can not be moved easily. Laser Induced Breakdown Spectroscopy (LIBS) is a technique which does not require that samples be subjected to a chemical pretreatment, and equipment is small and portable, this can save valuable time in coffee trading. The purpose of this research was to demonstrate that LIBS can be applied to solve various problems related with the coffee authentication. Green coffee pills with different concentrations of arabica and robusta varieties were analyzed by LIBS, the results were used in the construction of calibration curves for the detection of the degree of simulated adulteration in coffee. It was found that the relative intensities of Ca (392.4 nm), Sr (407.1 nm), N (500.5 nm) and Na (588.7 nm), as well as the intensity ratios of Ca II (392.4 nm)/N I (500.5 nm), Sr I (407.1 nm)/N I (500.5 nm)and N I (500.5 nm)/Na I (588.7 nm) can be used for this purpose. It is concluded that the differentiation of coffee and the detection of its adulteration is possible with the use of LIBS. Further, with the use of an Artificial Neural Network (ANN) of type Multilayer Perceptron, it was possible to correctly classify the spectra of arabica and robusta roasted coffee.

Abstract: An in vivo/in vitro cell model was used, culturing SMC isolated from chicks exposed to an atherogenic cholesterol-rich diet with 5% of cholesterol (SMC-Ch) alone or followed by an anti-atherogenic fish oil-rich diet with 10% of menhaden oil (SMC-Ch-FO) and from chicks on standard diet (SMC-C). Cells were exposed to 25-HC, studying apoptosis levels by flow cytometry (Annexin V) and expressions of caspase-3, c-myc, and p53 genes by quantitative real-time reverse transcriptase-polymerase chain reaction. Results: Exposure to 25-HC produced apoptosis in all three SMC cultures, which was mediated by increases in caspase-3, c-myc, and p53 gene expression. Changes were more marked in SMC-Ch than in SMC-C, indicating that dietary cholesterol makes SMC more susceptible to 25-HC-mediated apoptosis. Expression of p53 gene was elevated in SMC-Ch-FO. This supports the proposition that endogenous levels of p53 protect SMC against apoptosis and possibly against the development of atherosclerosis. Fish oil attenuated the increase in c-myc levels observed in SMC-C and SMC-Ch, possibly through its influence on the expression of antioxidant genes.Replacement of a cholesterol-rich diet with a fish oil-rich diet produces some reversal of the cholesterol-induced changes, increasing the resistance of SMC to apoptosis.Gene expression is influenced by dietary fat [1], gene transcription is regulated by dietary polyunsaturated fatty acids [2], and the nutritional control of gene regulation guides the transformation of SMC into foam cells in atherosclerosis [3]. The present study focused on the effect of cholesterol and fish oil intake on the expression of apoptosis-regulating caspase-3, c-myc and p53 genes.In the 1970 s, a very low incidence of death from ischemic heart disease was observed in Greenland Eskimos, who have a high fish consumption [4]. Evidence from several research lines supports the hypothesis that fish consumption may protect against atherosclerotic vascular disease. Fish oil
