Shannon entropy analysis of the genome code

This paper studies the chromosome information of twenty five species, namely, mammals, fishes, birds, insects, nematodes, fungus, and one plant. A quantifying scheme inspired in the state space representation of dynamical systems is formulated. Based on this algorithm, the information of each chromosome is converted into a bidimensional distribution. The plots are then analyzed and characterized by means of Shannon entropy. The large volume of information is integrated by averaging the lengths and entropy quantities of each species. The results can be easily visualized revealing quantitative global genomic information.

On the use of code mobility mechanisms in real-time systems

Applications with soft real-time requirements can benefit from code mobility mechanisms, as long as those mechanisms support the timing and Quality of Service requirements of applications. In this paper, a generic model for code mobility mechanisms is presented. The proposed model gives system designers the necessary tools to perform a statistical timing analysis on the execution of the mobility mechanisms that can be used to determine the impact of code mobility in distributed real-time applications.

FATAL GROUP A STREPTOCOCCAL TOXIC SHOCK-LIKE SYNDROME IN A CHILD WITH VARICELLA: REPORT OF THE FIRST WELL DOCUMENTED CASE WITH DETECTION OF THE GENETIC SEQUENCES THAT CODE FOR EXOTOXINS SPE A AND B, IN SÃO PAULO, BRAZIL

A previously healthy seven-year-old boy was admitted to the intensive care unit because of toxaemia associated with varicella. He rapidly developed shock and multisystem organ failure associated with the appearance of a deep-seated soft tissue infection and, despite aggressive treatment, died on hospital day 4. An M-non-typable, spe A and spe B positive Group A Streptococcus was cultured from a deep soft tissue aspirate. The criteria for defining Streptococcal toxic shock-like syndrome were fulfilled. The authors discuss the clinical and pathophysiological aspects of this disease as well as some unusual clinical findings related to this case.

Rol de las metaloproteasas y caspasas en la conducta biológica del carcinoma basocelular. Role of the metalloproteinases and caspasa Biology in the conduct of basal cell carcinoma.

El carcinoma basocelular (CBC) representa el tumor maligno más frecuente de la piel en personas de raza blanca. Incide en mayores de 50 años de edad e infiltra los tejidos, pero rara vez ocasiona metástasis. En trabajos anteriores, observamos imágenes de cuerpos apoptóticos con MOAR (microscopía óptica de alta resolución), en pieles portadoras de CBC. Todas las células eucariotas poseen una maquinaria enzimática que interviene en la apoptosis. Estas enzimas son las proteincinasas pertenecientes a la familia de las caspasas. Se sintetizan como procaspasas, las cuales una vez activadas, actúan sobre otra caspasa en una reacción secuencial en cadena. Se reconoce que la apoptosis juega un rol importante en el balance y mantenimiento de los tejidos. Hipótesis: -Investigar si la expresión de metaloproteasas y caspasas en las células del CBC promueven y contribuyen a la progresión y extensión tumoral. Objetivos:-Profundizar el conocimiento de la conducta biológica del CBC, en referencia a la relación de los patrones de crecimiento macro y microscópicos del tumor, enfatizando en la expresión de metaloproteasas (colagenasa-3 y streptomelisina), CD-31, Ki-67, oncoproteína bcl-2 y caspasas, mediante la implementación de técnicas de inmunohistoquímica. -Analizar a nivel morfológico la presencia de cuerpos apoptóticos por medio de MOAR y determinar si influyen en la conducta biológica del tumor. Materiales y Métodos: Se realizará un estudio retrospectivo y prospectivo de pacientes asistidos en el Servicio de Dermatología del Hospital Nacional de Clínicas, desde el año 2000. Se utilizarán tomas incisionales de piel, que se fijarán en formol neutro al 10 por ciento y luego serán procesadas e incluidas en parafina y coloreadas con H-E (hematoxilina-eosina). Especimenes seleccionados, se utilizarán para técnicas de MOAR e inmunocitoquímica. El material para MOAR, se fijará en Karnovsky enfriado a pH 7,2 y se incluirá en resinas epóxicas, seccionados con un ultramicrótomo Porter BluMT1 (1micra) y coloreados con P.A.S. azul de toluidina, fuscina básica y metenamina-plata. La aplicación de las técnicas inmunohistoquímicas, se utilizaran sobre cortes desparafinados con xilol, que permitirán investigar en forma retrospectiva y prospectiva la matriz extracelular (MEC) y los elementos neoplásicos. Los anticuerpos monoclonales a utilizar serán: Colageno tipo IV clone CIV 22 M0785 monoclonal antibody (DAKO), CD44 clone E29 M0613 monoclonal antibody (DAKO), Oncoproteina bcl-2 clone 124 M0887 monoclonal antibody (DAKO), CD31: clone 35 BH11 MO631 monoclonal antibody (DAKO) K-167 clone PC10 M0879 monoclonal antibody.(DAKO) bclx y Caspasa 8. Metodología Estadística Los resultados serán evaluados mediante: a) Varianza Anova; para datos con distribución gausiana como media, SD. b) Krusal Walles; para rasgos de distribución no gausiana. c) Chi2 para determinar la diferencia significativa para proporciones. Resultados esperados: Del análisis histomorfológico cualitativo y cuantitativo de biopsias de piel con CBC, aportar determinaciones que clarifiquen la conducta biológica de este tumor.- Importancia del Proyecto: El CBC es una entidad que está aumentando su incidencia en forma exponencial, debido sobre todo a pautas sociales. No sólo ocasiona trastornos en los pacientes, sino que también, representa gastos en el sistema de salud. Asimismo, significa un desafío para la investigación. Esto permite explorar aspectos de la biología molecular, a partir de una entidad que posee características únicas.

Implementation of Reed-Solomon RS (255,239) Code

In this paper the construction of Reed-Solomon RS(255,239) codeword is described and the process of coding and decoding a message is simulated and verified. RS(255,239), or its shortened version RS(224,208) is used as a coding technique in Low-Power Single Carrier (LPSC) physical layer, as described in IEEE 802.11ad standard. The encoder takes 239 8-bit information symbols, adds 16 parity symbols and constructs 255-byte codeword to be transmitted through wireless communication channel. RS(255,239) codeword is defined over Galois Field GF and is used for correcting upto 8 symbol errors. RS(255,239) code construction is fully implemented and Simulink test project is constructed for testing and analyzing purposes.

Quality control and conduct of genome-wide association meta-analyses.

Rigorous organization and quality control (QC) are necessary to facilitate successful genome-wide association meta-analyses (GWAMAs) of statistics aggregated across multiple genome-wide association studies. This protocol provides guidelines for (i) organizational aspects of GWAMAs, and for (ii) QC at the study file level, the meta-level across studies and the meta-analysis output level. Real-world examples highlight issues experienced and solutions developed by the GIANT Consortium that has conducted meta-analyses including data from 125 studies comprising more than 330,000 individuals. We provide a general protocol for conducting GWAMAs and carrying out QC to minimize errors and to guarantee maximum use of the data. We also include details for the use of a powerful and flexible software package called EasyQC. Precise timings will be greatly influenced by consortium size. For consortia of comparable size to the GIANT Consortium, this protocol takes a minimum of about 10 months to complete.

Substance use and suicidal conduct: a study of adolescents hospitalized for suicide attempt and ideation.

AIM: To study the prevalence of psychoactive substance use disorder (PSUD) among suicidal adolescents, psychoactive substance intoxication at the moment of the attempt, and the association between PSUD at baseline and either occurrence of suicide or repetition of suicide attempt(s). METHODS: 186 adolescents aged 16 to 21 y hospitalized for suicide attempt or overwhelming suicidal ideation were included (T0); 148 of them were traced again for evaluations after 6 mo (T1) and/or 18 mo (T2). DSM-IV diagnoses were assessed each time using the Mini International Neuropsychiatric Interview. RESULTS: At T0, 39.2% of the subjects were found to have a PSUD. Among them, a significantly higher proportion was intoxicated at the time of the attempt than those without PSUD (44.3% vs 25.4%). Among the 148 adolescents who could be traced at either T1 or T2, two died from suicide and 30 repeated suicide attempts once or more times. A marginally significant association was found between death by suicide/repetition of suicide attempt and alcohol abuse/dependence at baseline (OR=3.3, 95% CI 0.7-15.0; OR=2.6, 95% CI 0.7-9.3). More than one suicide attempt before admission to hospital at T0 (OR=3.2, 95% CI 1.1-10.0) and age over 19 y at T0 (OR=3.2, 95% CI 1.1-9.2) were independently associated with the likelihood of death by suicide or repetition of suicide attempt. CONCLUSION: Among adolescents hospitalized for suicide attempt or overwhelming suicidal ideation, the risk of death or repetition of attempt is high and is associated with previous suicide attempts--especially among older adolescents--and also marginally associated with PSUD; these adolescents should be carefully evaluated for such risks and followed up once discharged from the hospital.
