FRECUENCIA ALELICA Y GENOTIPICA PDF

Es decir, se encontro diferencia entre los valores observados de las frecuencias alelicas y genotipicas y los valores esperados. El genotipo II fue mas frecuente. TERMIUM® is the Government of Canada’s terminology and linguistic data bank. Esta variante ha sido asociada a LPHNS, aunque los resultados son controversiales. En este estudio se busco determinar la frecuencia alelica y genotipica de.

Tomando como prueba de referencia el cultivo, al analizar unicamente las muestras de esputo, la RCP directa proporciono una sensibilidad de 90,9 por ciento, una especificidad de 89,5 por ciento, un valor predictivo positivo de 52,6 por ciento y un valor predictivo negativo de 98,7 por ciento. Conducting this study permitted us to know the genotype, allele, and haplotype frequencies of the population analyzed and offers us useful tools to establish probabilities of finding compatible donors for patients in waiting lists for renal transplant.

The human leukocyte antigen system HLA of the major histocompatibility complex MHC contains a numerous family of genes located on the short arm of the 6th chromosome 6p The MPS-I is an autosomal recessive disorder caused by mutations in the IDUA gene that induce to a deficiency of glycosidase O-L-iduronidase that is required for degradation of heparan and dermatan sulfate.

None of the authors has conflicts of interest related to this study. Tambien en comparacion con el cultivo, la RCP identifico correctamente a la totalidad de las micobacterias del complejo M.

Polimorfismo en el codon 72 del gen p53 y riesgo de cancer cervico-uterino en Mexico by Angel Emilio Suarez-Rincon 1 edition published in in Spanish and held by 1 WorldCat member library worldwide A polymorphism at codon 72 in the p53 gen has been reported as a potential risk factor to cervical cancer CC because human papillomavirus HPV is more effective at degrading p53 Arg than p53 Pro, making individuals homozygous for p53 Arg seven times more likely to develop HPV-associated CC.

The results of the current study correspond mostly to that previously reported for Colombia, where we found a typical component of Latin population with an important Caucasian influence; nevertheless, the differences evidence the variations in the size and origin of the population studied, as well as the important influence of the resolution of the technique used in typifying. We conclude than In our population, as other worldwide countries, the homozygous for arginine at codon 72 of the p53 gene is not a risk factor to cervical cancer.

Because the allele frequencies and the disequilibrium patterns vary within a given population, the characterization of these molecules and the determination of their frequencies gain much pertinence and permits establishing parameters of association to disease in the population, which has a predictive value in managing self-immune diseases like Systemic Erythematosus Lupus SEL and Rheumatoid Arthritis RAalso becoming an important tool for the distribution of organs donated in the different transplant groups in the National Donation Network, as well as having an additional usefulness in estimating times the receptors must remain in the waiting list 9 Analysis of the p53 genotype at position 72 was performed by polymerase chain reaction using specific primers and Accll digestion.

The allele, genotype, and haplotype frequencies and those corresponding to demographic characteristics were calculated in the Stata 9. HLA gene and haplotype frequencies in the North American population: The results obtained provide a useful reference framework for the population studied, allowing compatibility probability calculations to be performed for organ transplants.

As In Mexico the CC is a health public problem, we designed this study to determinate whether the p53 codon 72 polymorphism represent a risk factor to CC in our population. The haplotype structure of the human aelica histocompatibility complex.

Association of human leukocyte antigen haplotypes with posttransplant lymphoproliferative disease after frecjencia organ transplantation. These antigens are expressed in autosomal and codominant manner and they are inherited from both parents, which is why each individual expresses an antigen of paternal origin and one of maternal origin for each of the loci 1.

Thus, the B15 frequency we found is higher than that reported in previous studies in Colombia. Benjamin A, Bradley T. Enzymatic activity and quantitative and qualitative studies of urinary glycosaminoglycans in five patients by Martha Patricia Gallegos Arreola 1 edition published in in English and held by 1 WorldCat member library worldwide Five patients presenting Hunter’s syndrome were biochemically studied.

The normality of the age variable was evaluated by using the Shapiro-Wilk test and summarized with a mean.

Most of the Latin American populations studied are of indigenous origin or barely mixed 11 – Clinical features and prognosis of HLA-B27 positive and negative anterior uveitis in a Korean population. Analysis of the frequencies of HLA-A, B, and C alleles and haplotypes in the five major ethnic groups of the United States reveals high levels of diversity in these loci and contrasting distribution patterns in these populations.

Given the heterogeneity of the population analyzed in the current study, it is important to keep the following aspects in mind: Un procedimiento controlado de RCP permite establecer o excluir el diagnostico de tuberculosis en un alelia que se reduce de m s de tres semanas a tan solo 24 a 48 horas, lo cual resulta particularmente util cuando es necesario un diagnostico temprano para establecer el pronostico del paciente o en casos de transplante de organos.

Se analizaron muestras de esputo, 96 de orina, 15 de LCR y 27 de otros tipos de pacientes con sospecha de tuberculosis en cualquiera de sus formas que frecuenciaa al Laboratorio de Patologia Clinica del Hospital de Especialidades del Centro Medico Nacional de Occidente del Instituto Mexicano del Seguro Social. The HLA dictionary In its generic sense, the term frequency refers to occurrences which may be either absolute or relative. For this reason, more than having healthy individuals or patients in the population the origin does set an important relevant factor with respect to the distribution of frequencies.

Frecuencias genotípicas, fenotípicas y alelicas by Mary Garcia on Prezi

Proportions were calculated to summarize the qualitative variables. When comparing our results to the study with the population in the city of Bogota published by Ossa et al.

The p values lower than or equal to 0. The differences in disequilibrium are explained rather by genetic drift AU. The results obtained in this study correlate to those previously reported for a Latin American population, where the alleles with the greatest frequency were A02, A24, Frecuencis, and A68 1415 These results show evidences of henotipica differences in thys syndrome AU.

A collection of writing tools that cover the many facets of English and French grammar, style and usage. It was possible to determine the level of the A locus for 19 alleles, similar to those reported by Ossa et al. Electrophoresis revealed the presence of heparan sulfate HS and dermatan sulfate DS in four cases 80 perecentbut in the remaining patient, only DS was present. Project Page Feedback Known Problems. X2 test showed no significant difference In the proportions.

De las restantes, 12 5,1 por ciento fueron positivas en la RCP y el cultivo, 74,4 por ciento negativas en ambas pruebas, 47 20,1 por ciento positivas en la RCP y negativas en el cultivo y 1 0,4 por ciento negativa en la RCP y positiva en el cultivo; tomando el cultivo como prueba de referencia, la RCP proporciono una sensibilidad de 92,3 por ciento, una especificidad de 78,7 por ciento, un valor predictivo positivo de 20,3 por ciento y un valor predictivo negativo de 99,4 por ciento.

The high polymorphism of the HLA system and advancements in molecular biology have permitted for the typifying of these antigens to become important tools in establishing associations of susceptibility or resistance to disease, development of tumor processes; playing an important role in understanding the variability of the immune response and determinant on the survival of organ or tissue transplants 2 – 8.

The samples had been taken after obtaining signed informed consent from the patients or their families and through medical request. This study used data from patients whose samples had already been taken and processed; hence, there was no additional risk.

In controls the proportions were 0. En todos los casos se realizo tincion de Ziehl-Neelsen, cultivo en medio de L”wenstein-Jensen y amplificacion por RCP de un segmento de pares de bases especifico del complejo M.
