A meta-analysis of 87,040 individuals identifies 23 new susceptibility loci for prostate cancer

Genome-wide association studies (GWAS) have identified 76 variants associated with prostate cancer risk predominantly in populations of European ancestry. To identify additional susceptibility loci for this common cancer, we conducted a meta-analysis of > 10 million SNPs in 43,303 prostate cancer cases and 43,737 controls from studies in populations of European, African, Japanese and Latino ancestry. Twenty-three new susceptibility loci were identified at association P < 5 × 10(-8); 15 variants were identified among men of European ancestry, 7 were identified in multi-ancestry analyses and 1 was associated with early-onset prostate cancer. These 23 variants, in combination with known prostate cancer risk variants, explain 33% of the familial risk for this disease in European-ancestry populations. These findings provide new regions for investigation into the pathogenesis of prostate cancer and demonstrate the usefulness of combining ancestrally diverse populations to discover risk loci for disease.

Optical properties change in amorphous (As2S3)(0.87)Sb-0.13 thin films by photo and thermal induced process

Exposure with above band gap light and thermal annealing at a temperature near to glass transition temperature, of thermally evaporated amorphous (As2S3)(0.87)Sb-0.13 thin films of 1 mu m thickness, were found to be accompanied by structural effects, which in turn, lead to changes in the optical properties. The optical properties of thin films induced by illumination and annealing were studied by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and Raman spectroscopy. Photo darkening or photo bleaching was observed in the film depending upon the conditions of the light exposure or annealing. These changes of the optical properties are assigned to the change of homopolar bond densities. (C) 2010 Elsevier B.V. All rights reserved.

A PRACTICAL PROCEDURE TO ESTIMATE THE BEARING CAPACITY OF FOOTINGS ON SAND-APPLICATION TO 87 CASE STUDIES

Following the recent work of the authors in development and numerical verification of a new kinematic approach of the limit analysis for surface footings on non-associative materials, a practical procedure is proposed to utilize the theory. It is known that both the peak friction angle and dilation angle depend on the sand density as well as the stress level, which was not the concern of the former work. In the current work, a practical procedure is established to provide a better estimate of the bearing capacity of surface footings on sand which is often non-associative. This practical procedure is based on the results obtained theoretically and requires the density index and the critical state friction angle of the sand. The proposed practical procedure is a simple iterative computational procedure which relates the density index of the sand, stress level, dilation angle, peak friction angle and eventually the bearing capacity. The procedure is described and verified among available footing load test data.

Comportamiento agro-industrial de catorce variedades de caña de azúcar (Saccharum sp hibrido L.) en comparación con las variedades Ja 60-5 y C 87-51

El presente trabajo se llevó a cabo en el ciclo 92-93 en el Ingenio Victoria de Julio, donde se evaluaron 14 variedades de caña de azúcar en comparación con las variedades Ja 60 - 5 y C 87 - 51 para determinar el comportamiento agro-industrial de estos cultivares y seleccionar los genotipos más sobresalientes. El experimento fue establecido el 25 de enero de 1992, en un suelo arcilloso de la serie Chilamatillo, la cosecha se realizó a los 11 meses de edad del cultivo, el 16 de Dic 1992. El diseño utilizado fue de bloques completos al azar con 5 repeticiones, las variables estudiadas fueron: Germinación, población, altura de tallos, floración, diámetro de tallos, peso promedio de los tallos, rendimiento agrícola, rendimiento industrial y rendimiento agro-industrial. Los datos fueron sometidos a un análisis de varianza y prueba de tukey al 5% de margen de error. Los resultados obtenidos fueron los siguientes: Germinación; siendo las mejores RB 73-1012, CP 70-321 y Q 96. Población;las mejores numéricamente resultaron Méx 68-P 23,SP 70-1284 y SP 72-4790. Longitud de tallo; las mejores variedades fueron la SP 72-4790, Q 96, RB 73-1012 y RB 73-5220. Diámetro de los tallos; obtuvo el mejor resultado la variedad Méx 69-420 y en segundo lugar la Ja 60-5. Peso promedio de 100 tallos. ; presentando el mejor resultado el cultivar Méx 69-420 seguido de la RB 73-5220. Floración; todas las variedades florecieron a excepción del testigo C 87-51. Rendimiento agrícola; obtuvo el mejor resultado la variedad Méx 68-P 23 ocupando el segundo lugar SP 72-4790; Rendimiento industrial; entre las variedades sobresalieron numéricamente la Q 96 seguido de la C 87-51 y la CP 72-1210. Rendimiento Agro-Industrial; de acuerdo a los resultados de rangos múltiples la variedad Q 96 presenta un rendimiento estadísticamente superior a la variedad testigo Ja 60-5, superando numéricamente al resto de variedades. Las variedades que presentaron afectaciones por enfermedades fueron : RB 76-5288, SP 70-1284, SP 72-4790, CP 72-1210, SP 71-61801 CP 72-2086, Méx 69-420, Méx 68-P23, Ja 60-5 y e 87-51.
