Studies on the Deep - Water Crab Charybdis (Goniohellenus ) Smithii Macleay From the Seas Around India

The present study deals with a general introduction which outlines the objective of the study providing an exhaustive review of works on crabs with particular reference to deep-sea forms. In the first section, Taxonomy and Geographical disribution of the crab are dealt with. The species is described in detail based on several male and female specimens obtained from the pelagic and bottom collections, and its identity in Indian waters is established. It is also distinguished from a closely allied species so far not reported from Indian waters. The second section comprises the biology of the species and it is dealt with under four subheading, namely Habit and Habitats, Reproduction, Food and feeding and Proximate composition. The different habitats occupied by juveniles, subadults and adults of the species have been described and discussed in the light of available information on differential distribution of other related species. The reproductive biology is described in various details touching on gross anatomy and histology of the reproductive systems, spermatogenesis, oogenesis, size at maturity, ovarian maturation process, fecundity, egg carriage and breeding. The food and feeding habits of the species have been studied with reference to the different life stages such as juveniles, subadults and adults during the different phases of life based on stomach content analysis. The percentage of meat recovery and protein, carbohydrate and lipid content of meat have been described in the section dealing with proximate composition. In section three the distribution and abundance of the crab for the entire Indian EEZ and some contiguous ares have been described and illustrated in detail separately for pelagic and benthic realms. The size frequency disrtibution, sex ratios, length weight relationship and relative abundance of breeding population in the experimental catches have been dealt with in detail and discussed.

Bionomics, cryopreservation of gametes and captive breeding behaviour of threatened hillstream cyprinid, garra surendranathanii(shaji, arun & easa, 1996)

Garra surendranathanii is a hill stream cyprinid endemic to Kerala. According to IUCN based classification, G. surendranathanii is grouped under the threatened category. This endemic fish is having highly restricted and fragmented distribution and reported only from 5 river systems viz. Chalakudy, Periyar, Pamba, Achenkoil and Bharathapuzha. Categorization of this fish as a potential ornamental candidate can invariably add more pressure on the threat status of this particular species. Hence, this species is considered as one which requires foremost attention for conservation. Hitherto, no infomiation is available on the bionomics, resource characteristics and any conservation attempts of G. surendranathanii. Studies on detailed life history traits and development of captive breeding technique are indispensable for successful fishery management.The present study was undertaken with the following obj ectives: To study the Length-weight relationship and condition factor to ascertain the relationship between length and weight and general wellbeing ofthe fish To study the age and growth to understand the age composition of the exploited stock, age at first maturation and life span of the species. To study the reproductive biology of G. surendranathanii to gain insights in the process of gametogenesis, spawning, sex ratio, fecundity and other related aspects which are essential for developing captive breeding technology of this species. To develop captive breeding technology and cryopreservation ofgametes of G. surendranathanii for conservation

Development of CHH family recombinant hormones and RNAi for induced maturation of Penaeus monodon

About 80 years ago, the neurosecretory eyestalk structures and their role in endocrine regulation was recognized in crustaceans. After the recognition it took half a century to identify the first peptide hormone. Till date a large number of homologous peptides of crustacean hyperglycaemic hormone and moult-inhibiting hormone have been identified, consequently they are called the CHH family hormones. This family comprises of highly multifunctional peptides which according to sequences and precursor structures can be divided into two subfamilies, type-I (CHH/ITP) and II (MIH, MOIH, VIH/GIH) (Webster et al., 2012). The XO-SG complex has been the major site of the two subfamilies. The advent of molecular techniques resulted in the characterization of different precursors of CHH, MIH and GIH; these hormones consist of a signal peptide, but only the preprohormone of CHHs contain a precursor- related peptide (CPRP) located between the signal and the mature hormone (Weidemann et al., 1989; Klein et al., 1993b; De Kleijn and Van Herp, 1995). The essentialities of the gene structure comply with the functions of the CHH family hormones. The CHH family hormone functions are inhibitory as well as stimulatory in the process of reproduction and maturation

Nitrification in a packed bed bioreactor integrated into amarine recirculating maturation system under different substrate concentrations and flow rates

BACKGROUND: A packed bed bioreactor (PBBR) activated with an indigenous nitrifying bacterial consortia was developed and commercialized for rapid establishment of nitrification in brackish water and marine hatchery systems in the tropics. The present study evaluated nitrification in PBBR integrated into a Penaeus monodon recirculating maturation system under different substrate concentrations and flow rates. RESULTS:Instantnitrificationwasobservedafter integration ofPBBRinto thematuration system.TANandNO2-Nconcentrations were always maintained below0.5 mg L−1 during operation. The TANandNO2-N removalwas significant (P < 0.001) in all the six reactor compartments of the PBBR having the substrates at initial concentrations of 2, 5 and 10 mg L−1. The average volumetric TAN removal rates increased with flow rates from 43.51 (250 L h−1) to 130.44 (2500 L h−1) gTAN m−3 day−1 (P < 0.05). FISH analysis of the biofilms after 70 days of operation gave positive results with probes NSO 190 ((β ammonia oxidizers), NsV 443 (Nitrosospira spp.) NEU (halophilic Nitrosomonas), Ntspa 712 (Phylum Nitrospira) indicating stability of the consortia. CONCLUSION: The PBBR integrated into the P. monodon maturation system exhibited significant nitrification upon operation for 70 days as well as at different substrate concentrations and flow rates. This system can easily be integrated into marine and brackish water aquaculture systems, to establish instantaneous nitrification

Asociación entre relaciones románticas y la calidad de sueño percibida por jóvenes universitarios

Introducción: Uno de los aspectos con mayor variación durante la adolescencia es el sueño, el cual se ve afectado por factores biológicos así como por los estados afectivos y emocionales. En esta etapa, los individuos establecen sus primeras relaciones sentimentales románticas, vínculos esenciales para la maduración de las relaciones sociales y psicosexuales. Este trabajo busca determinar la asociación existente entre las relaciones sentimentales románticas y sus características, con la calidad sueño percibida por los jóvenes. Metodología: Estudio realizado en una población de 1794 estudiantes de ciencias de la salud entre los 18 y 25 años de edad en Bogotá, Colombia, entre 2012 y 2013. Se obtuvo una muestra probabilística con asignación proporcional de 443 sujetos, estratificada por programa académico y sexo. Utilizando dos cuestionarios de auto reporte se exploraron las características de las relaciones sentimentales y la calidad de sueño percibida. Resultados: El 64% (IC 95%: 59,4-68,9%) de la población estudiada se encontró en una relación sentimental romántica. Estos sujetos tuvieron latencias de sueño prolongadas con menor frecuencia que quienes no tenían en una relación (p <0,05). La calidad de sueño percibida se asoció al nivel de satisfacción que tuvieron los sujetos en su relación, así como la atracción por su pareja. Rasgos obsesivos, ansiosos, temerosos y evitativos en la relación disminuyeron la calidad de sueño percibida. Conclusión: Las relaciones sentimentales románticas y sus características se asocian con la calidad de sueño percibida por los individuos. Se requieren estudios que determinen causalidad en esta asociación y definan potenciales estrategias de intervención al respecto.

The recognition of rights to same-sex couples: the path towards a pluralistic concept of family

This paper presents the final results of the research project undertaken in 2010 and 2011 by the legal research group “Filius”, affiliated with Corporación Universitaria Empresarial Alexander von Humboldt of Armenia, (Quindío). The project’s general objective is “to establish the concept of family used by the Colombian legal system based on the judgments of the Constitutional Court granting rights to same-sex couples”. To this end, a line of jurisprudence was developed from the Court’s rulings that discussed the rights of same-sex couples, concluding that despite the great progress made in Colombia on the recognition of rights to these couples following Decision C-075/2007, in all these judgments the Court had always refused to recognize their family status, and it was not until 2011, in Decision C-577, that the Court accepted that same-sex couples constitute a family, thereby dramatically changing the constitutional doctrine that had maintained the criteria of heterosexuality as defining family.

Recognition of static and dynamic facial expressions: Influences of sex, type and intensity of emotion

Ecological validity of static and intense facial expressions in emotional recognition has been questioned. Recent studies have recommended the use of facial stimuli more compatible to the natural conditions of social interaction, which involves motion and variations in emotional intensity. In this study, we compared the recognition of static and dynamic facial expressions of happiness, fear, anger and sadness, presented in four emotional intensities (25 %, 50 %, 75 % and 100 %). Twenty volunteers (9 women and 11 men), aged between 19 and 31 years, took part in the study. The experiment consisted of two sessions in which participants had to identify the emotion of static (photographs) and dynamic (videos) displays of facial expressions on the computer screen. The mean accuracy was submitted to an Anova for repeated measures of model: 2 sexes x [2 conditions x 4 expressions x 4 intensities]. We observed an advantage for the recognition of dynamic expressions of happiness and fear compared to the static stimuli (p < .05). Analysis of interactions showed that expressions with intensity of 25 % were better recognized in the dynamic condition (p < .05). The addition of motion contributes to improve recognition especially in male participants (p < .05). We concluded that the effect of the motion varies as a function of the type of emotion, intensity of the expression and sex of the participant. These results support the hypothesis that dynamic stimuli have more ecological validity and are more appropriate to the research with emotions.

Percentiles de grasa corporal por bioimpedancia eléctrica en niños y adolescentes de Bogotá, Colombia: Estudio FUPRECOL

Objetivo: Recientemente, se han propuesto varios dispositivos de impedancia bioeléctrica (BIA) para la estimación rápida de la grasa corporal. Sin embargo, no han sido publicadas referencias de grasa corporal para niños y adolescentes en población Colombiana. El objetivo de este estudio fue establecer percentiles de grasa corporal por BIA en niños y adolescentes de Bogotá, Colombia de entre 9 y 17.9 años, pertenecientes al estudio FUPRECOL. Métodos: Estudio descriptivo y transversal, realizado en 2.526 niños y 3.324 adolescentes de entre 9 y 17.9 años de edad, pertenecientes a instituciones educativas oficiales de Bogotá, Colombia. El porcentaje de grasa corporal fue medido con Tanita® Analizador de Composición Corporal (Modelo BF-689), según edad y sexo. Se tomaron medidas de peso, talla, circunferencia de cintura, circunferencia de cadera y estado de maduración sexual por auto-reporte. Se calcularon los percentiles (P3, P10, P25, P50, P75, P90 y P97) y curvas centiles por el método LMS según sexo y edad y se realizó una comparación entre los valores de la CC observados con estándares internacionales. Resultados: Se presentan valores de porcentaje de grasa corporal y las curvas de percentiles. En la mayoría de los grupos etáreos la grasa corporal de las chicas fue mayor a la de los chicos. Sujetos cuyo porcentaje de grasa corporal estaba por encima del percentil 90 de la distribución estándar normal se consideró que tenían un elevado riesgo cardiovascular (chicos desde 23,4-28,3 y chicas desde 31,0-34,1). En general, nuestros porcentajes de grasa corporal fueron inferiores a los valores de Turquía, Alemania, Grecia, España y Reino Unido. Conclusiones: Se presentan percentiles del porcentaje de grasa por BIA según edad y sexo que podrán ser usados de referencia en la evaluación del estado nutricional y en la predicción del riesgo cardiovascular desde edades tempranas.

Valores del índice cintura/cadera en población escolar de Bogotá, Colombia: Estudio

Objetivo: Determinar los valores del índice cintura/cadera (ICC) en una población escolar de Bogotá, Colombia, pertenecientes al estudio FUPRECOL. Métodos: Estudio descriptivo y transversal, realizado en 3.005 niños y 2.916 adolescentes de entre 9 y 17,9 años de edad, pertenecientes a 24 instituciones educativas oficiales de Bogotá, Colombia. Se tomaron medidas de peso, talla, circunferencia de cintura, circunferencia de cadera. El estado de maduración sexual se recogió por auto-reporte. Se calcularon los percentiles (P3, P10, P25, P50, P75, P90 y P97) según sexo y edad y se realizó una comparación entre los valores del ICC observados con estándares internacionales. Resultados: De la población general (n=5.921), el 57,0% eran mujeres (promedio de edad 12,7 ± 2,3 años). En todas las edades el ICC fue mayor en los varones que en las mujeres, observándose un descenso en la media de los valores obtenidos desde los 9 hasta los 17,9 años. En varones, los valores del ICC mayores del P90 (asociados a riesgo cardiovascular) estuvieron en el rango 0,87 y 0,93 y en las mujeres entre 0,85 y 0,89. Al comparar los resultados de este estudio, por grupos de edad y sexo, con trabajos internacionales de niños y adolescentes de Europa, Suramérica, Asia y África, se observa que los valores del ICC fueron menores en este estudio en ambos sexos, con excepción de los escolares originarios de Grecia y Venezuela. Conclusiones: Se presentan percentiles del ICC según edad y sexo que podrán ser usados de referencia en la evaluación del estado nutricional y en la predicción del riesgo cardiovascular desde edades tempranas en población de Bogotá, Colombia.
