BIK/NBK gene as potential marker of prognostic and therapeutic target in breast cancer patients

PURPOSE: The purpose of this study is to determine the association between the BIK/NBK gene expression and estrogen receptor alpha expression. MATERIALS AND METHODS: We determined the association of BIK/NBK gene expression by real time quantitative reverse transcription polymerase chain reaction and estrogen receptor alpha expression by immunohistochemistry in samples of breast cancer tissue. RESULTS: We found a statistically significant correlation of BIK/NBK gene expression with the estrogen receptor alpha expression (ρ = 0.751, p = 0.004). For verify differences of BIK/NBK gene expression among ERα+ and ERα- breast cancer tissues, Mann-Whitney U test was performed, obtaining significant differences. CONCLUSIONS: BIK/NBK gene expression may have important clinical implications and provide predictive, prognostic or therapeutic marker in breast cancer patients according to the estrogen receptor alpha expression (AU)

Una aproximación a la integración de diferentes medidas de regulación emocional / Theoretical integration of different measures of emotional regulation

El presente estudio examina la posibilidad de integración teórica de diferentes medidas de regulación emocional. En concreto se analiza la relación empírica existe entre ellas con el objetivo de comprendermejor los mecanismos sobre os que trabaja el mnejo emocional. En el estudio participaron 161 estudiantes univrsitarios que fueron evuados a través de tres medidas de regulació emocional: Inteligencia Emocional Percibida (TMMS); Estrategias de Supresión emocional y Reevaluación Cognitiva (ERQ); Afrontaietno Emocional (EAC) y en variales criteio como la Autoestima y la Satisfacción Vital (SWLS). Además este estudio investiga la validez incrmental, convergente y discriminanate de las medids de regulación emocinal para explicar la varianza de diferentes variables criterio: la satisfacción vital y la autoestima. Los resultados obtenidos fueron en la dirección esperada, mosrando que las dimensiones d elas diferentes corrientes estudiadas parecen estar evluando en la práctica el mismo tipo de estrategias de manejo emocional(AU)

This study examines the possibility of theoretical integration of different measure of emotional regulation. In particular, we analyse the empirical relationship existing between such measures with the aim of gaining a better understanding of the mehanisms on which emotional management operates. The study was carried out with 161 undergraduates that were evaluated through three measures of emotinl regulation: Perceived Emotional Inelligence (TMMS); Emotional Suppression and emotional reappraisl strategies (ERQ), Emotional copig (EAC) and in criterion variabes such as Self-Esteem and Life Satisfaction (SWLS). Likeise, the present study investigates the incremental, convergent and disriminant validity of emotional regulation measures to account for the variance of the several criterion variables: life satisfaction and self-esteem. The results obtained pointed to expected direction, showing that the dimensions of the various tendencies studied seem to be assessing in practice the same type of emotional management strategies(AU)

Inteligencia emocional, estilos de respuesta y depresión / Emotional intelligenc, responses styles and depression

Basándonos en el modelo teórico de IE Mayer y Salovey (1997) el presente estudio analizó ls relacines entre la inteligencia emocional, evaluada con el Trait meta-Mood Scale (TMMS) y el Mayer Salovey Caruso Emotional Intelligence Test (MSCEIT), los estilos de respuestas rumiativo/distractor (Response Styes Questionnaire; RSQ),y los nivels de depresión (Beck Depresion Inentory; BDI). También se evaluó la valiez predictiva e incremental de la IE sobre depresión, controlando las variable sociodemográficas y los estilos de respuesta. En general, los resuados mostraro que, aunque el estilode respuesta era el predictor más signification, no obstante, la inteligencia emocional mostró vaianza odesta aunque significativa, Cuando se dividió a la muesra en diferentes grupos, el grupo de personas con depresión grave y lgera mostró menos habilidades emocionales que el grupo normal. Los hallazgos del presente estudio apoyan la consideración de la inteligencia emocional como un constructo teóricamnte relevante y empíricaente predictivo de ls diferencias individuales en sintomatología depresiva(AU)

Based upon Mayer and Salovey´s El model (1997), the purpose of the present study was toinvestigate the relationship between, emotinal intelligence, assessed by the Trait Meta-Mood Scale (TMMS) and the Mayer Salovey Caruso Emotional Inelligence Test (MSCEIT), the responses styles to depressed mood (rumination and distraction sytles) and the levels of deprssion (Beck Depression Inventory; BDI) in a wide sample of high shool and university students. The predictive validity of emotional controling for the effects of socio-demografic variables nd different responses styles was also examined. In general, the results showed that although responss styles were the most significant predicotr for depresion, however, emoional intelligence predicted modest but significant variance. Finally, when the sample ws divided into different groups, the slight and moderate-severe depression groups reported less emotional abiities that the normal group. Our findings support the consideration of El as a theoretically relevant construt and predictive empirically individual differences in accounted for depression(AU)

Inteligencia emocional percibida y consumo de tabaco y alcohol en adolescentes / Emotional intelligence and teenagers alcohol/tobacco consumption

Esta investigación examinó la relación entre la inteligencia emocional (IE) y el consumo de alcohol y tabaco en adolescentes. A IE entendida como la capacidad para percibir, comprender y regular las emociones de manera adecuada, se asocia con la disminución de conducas de risgo para la salud en las que se incluye el consumo de tabaco y alcohol. La hipóteis de nuestro estudio es que las personas que tengan más desarrolladas estas habilidades nor ecurrirán al consumo de drogas para regular sus estados emocionales negativos. En el etudio participaron alumnos de entre 11 y 21 años. Para evaluar la IE utilizamos el Trait Meta Mood Scale y para evaluar el consumo de sustancias adictivas empleamos el cuestionario sobr drogas del Observatorio Nacional sobre drogas. Los adolescentes con una mayor puntuación en IE muestran un menor consumo de tabaco y alcohol. Los adoescentes conuna menor puntuación en IE recurren al consumo de estas sustancias como una forma externa de autoregulación emocional(AU)

The investigacition examined the relationship between emotional intelience (EI) and teenae alcohol /tobacco consumption. Emotional intelligence, understood as the ability to perceive, undersand and regulate emotions in an adequate way, is associeated to a reduction in conducts entailing a risk for health, including tobacco and alcohol consumption. They hypothesis of our study is that persons who have developed these abilties to a larger extent shall not resort to drug consumption in order to regulate their negative emotional states. The participants of the study were students aged between 11 and 21. In order to evaluate emotional intelligence, we used the Trait Meta Mood Scale and to evaluate consumption of addictive substances we resorted to he questionnaire on drugs of the National Observatory on Durgs. Teenagers scoring higher in Emotional Intelligence reveal smaller tobacco and alcohol consumption levels. Teenagers scoring lower in Emotional Intelligence resort to consumption of these substances as an external form of emotional self-regulation(AU)

Ingestión y digestión de siete especies de microalgas por larvas de Strombus gigas (Mesogastropoda: Strombidae) / Ingestion and digestion of seven species of microalgae by larvae of Strombus gigas (Mesogastropoda: Strombidae)

The potential nutritional value of seven microalgal diets as measured by their ingestibility and digestibility to queen conch Strombus gigas larvae was tested with 30 day old larvae reared at 28 degrees C and fed at 1000 cells x ml(-1). The algae were Tetraselmis suecica, Tetraselmis chuii Isochrysis aff. galbana, Dunaliella tertiolecta, Chlamydomonas coccoides, Chaetoceros sp. and Thalassiosira fluviatilis. Ingestion and digestion were measured by the four nutritional stages studied with epifluorescence microscopy with live larvae. Temporal and absolute indices showed that larvae fed Chaetoceros sp. and T. fluviatilis had lower ingestion and digestion levels. The other algae are recommend to feed S. gigas larvae.

Producción somática de dos especies de Crassostrea virginica e Ischadium recurvum (Bivalvia) en Mecoacán, Tabasco, México / Somatic production of two species: Crassostrea virginica and Ischadium recurvum Bivalvia in Mecoacán, Tabasco, México

The Mexican oyster fishery, 90% supported by the coastal lagoons of the Gulf of Mexico, has decreased drastically in the last six years as a result of anthropogenic pollution and improper management. The mussel Ischadium recurvum has proliferated and competes with oysters for space and probably food. Crassostrea virginica and Ischadium recurvum were studied to evaluate somatic production with biometry and physiological condition indices (PCI's) during an annual cycle. A random sample of 200 organisms was taken montly for each species. Condition indices wet flesh weigth: wet shell weight ratio (WFW/WSW), dry flesh weight: wet flesh weight ratio (DFW/WFW), dry flesh wet: dry shell weight ratio (DFW/DSW), and ash free dry weight: tissue dry weight (AFDW/TDW) were calculated. In order to stablish physiological condition and temporal variability, these indices were compared between species and months. The somatic production of mussels was higher than in oysters. This enhancement in production could be explained by: 1) Mussel uses less energy for shell production, 2) a constant recruitment of mussel almost year-round, and 3) the mesohalin lagoon was more favourable to the mussel.

Desarrollo embrionario de Strombus pugilis (Mesogastropoda: Strombidae) en el laboratorio / Embrionary development of Strombus pugilis (Mesogastropoda: Strombidae) in the laboratory

Stages from oviposition to veliger hatching are described for Strombus pugilis under laboratory conditions. Two egg masses from Playa Seyba, México, (20 degrees 45' N, 91 degrees 45' W) were used (three sub-samples per mass). Each sub-sample was immersed in a 11 container at 29 +/- 1 degrees C. This description is based on stages known from Strombus gigas, which include number of: fertilized eggs, morulae, gastrulae, trochophore larvae with slow movements, larvae with primordium foot, larvae with eyes, larvae with statocyst and veliger larvae. Eggs with first division appeared five hours after oviposition in the three replicates of each mass, although in greatest number in one of the egg masses. Trochophore larvae with slow movements appear after 50-54 hours and veligers hatch after 90 hours.

Distribución, abundancia, densidad y morfometría de Strombus gigas (Mesogasteropoda: Strombidae) en el Arrecife Alacranes, Yucatán, México / Distribution, abundance, density and morphometry of Strombus gigas (Mesogasteropoda: Strombidae) in Alacranes reef, Yucatán, México

A population of the conch Strombus gigas was sampled in 109 transects (100 x 10 m each) for an area of 109000 m2 (eight surveys in 1998 and six in 1999) in Yucatan, Mexico; S. gigas was the most abundant conch species (97% of individuals) and ocurred at depths of 0.5-18 m. Mean density was 0.0084 individuals/m2 (Standard deviation SD=0.0138, n=1910). Maximum density (0.015 individuals/m2) was at 0.5-2 m and minimal (0.001 individuals/m2) at 16-18 m. Shell length was 120-290 mm (mena=211.6, SD=26, n=1136). Shell lip thickness, measured only in adults, was 1-28 mm (mean=8.7, SD=7.5, n=1136).

Crecimiento y sobrevivencia de semillas del ostión Crassostrea virginica en una granja camaronícola en Yucatán, México / Growth and survival of seeds of the Crassostrea virginica oyster on a shrimp farm in Yucatán, México

A lot of 1600 seeds of American oyster Crassostrea virginica from the coastal lagoon La Redonda, Tabasco, Mexico was cultured in main drainage channel (S1), a secondary drainage channel (S2), the floodgate of a white shrimp Pennaeus vannamei pond (S3) and the marine water supply pond (S4). The seeds, with a total height and initial humid weight of 31.67 +/- 3.43 mm and 4.29 +/- 1.32 g, respectively, were cultured in suspended Nestier oyster boxes at 575 org/m2. Biological and environmental parameters were recorded after 296 days, the seeds in S4 reached height and weight values of 52.55 +/- 7.51 mm and 16.30 +/- 4.94 g, respectively. The index of physiologic condition along the experiment had a variation of 1.26% to 3.45%. In S4 the survival was 81.0%. In the other places the mortality was total after 90 days.

Ciclo reproductor e índices de condición usados en Melongena corona (Mollusca: Gastropoda) / Reproductive cycle and index of condition used for Melongena corona (Mollusca: Gastropoda)

Melongena corona bispinosa was studied in Yucatán, México (21 degrees 16' N, 89 degrees 49' W) for a year. Males have reproductive peaks in February and December, and a post-copulation peak in June. Female peaks are in March and May, plus oviposition peaks in April and January. Males and females differ in the mean gonadosom ic index (F=13.79, p<0.05) but not in the dry tissue/shell weight (F=0.0902, p<0.05), dry tissue and total weight (F=0.2466, p<0.05) and dry tissue weight/internal shell volume (F=1.0565, p<0.05).

Fiabilidad de las medidas electrofisiológicas del control motor / Reliability of electrophysiological measurements in motor control

Objetivo. Localizar las regiones corticales que soportan la función del lenguaje en pacientes que van a someterse a una intervención quirúrgica cerebral. Pacientes y métodos. Hemos estudiado con tomografía computarizada por emisión de fotón único (SPECT) de perfusión cerebral a 14 pacientes con epilepsia temporal farmacorresistente candidatos a tratamiento quirúrgico. Los pacientes se eligieron de forma consecutiva entre los que acudían para su valoración prequirúrgica. Se seleccionaron aquellos enfermos en los cuales pudo realizarse dos estudios con 99mTc-HMPAO en la misma semana: uno en reposo sensorial y otro durante la escucha y repetición de una serie de palabras con baja imaginabilidad y frecuencia de uso medio. Se valoraron ambos estudios de forma cualitativa (imagen en escala de 16 colores, con sustracción del 20 por ciento de fondo y normalizadas al punto de máxima captación), y se consideraron cambios significativos, cuando se localizaba un aumento de intensidad mayor de dos colores, y semicuantitativos (con áreas de interés regulares, de 4 ¥4 píxeles, colocadas sobre la región donde se apreciaba el cambio cualitativo y referenciadas a la actividad de cerebelo). Resultados. Se encontraron aumentos de la perfusión en las regiones temporoparietales, en 11 de los 14 pacientes. En la mayoría (9/14 casos) fueron bilaterales y en dos casos solamente izquierdo. Se observó un cierto patrón predominante: aumento de perfusión temporal bilateral, con implicación de las regiones más anteriores del hemisferio izquierdo, así como medias y posteriores del derecho. El porcentaje de incremento máximo de la perfusión en la valoración semicuantitativa fue del 12 por ciento. Conclusión. Aunque los cambios observados pueden corresponder a la activación de regiones corticales relacionadas con diversas funciones cerebrales, consideramos que con la técnica de SPECT son detectables cambios de perfusión en las regiones cerebrales que intervienen durante el proceso del lenguaje (AU)
