Phenotypic divergence but not genetic distance predicts assortative mating among species of a cichlid fish radiation.

The hypothesis of ecological divergence giving rise to premating isolation in the face of gene flow is controversial. However, this may be an important mechanism to explain the rapid multiplication of species during adaptive radiation following the colonization of a new environment when geographical barriers to gene flow are largely absent but underutilized niche space is abundant. Using cichlid fish, we tested the prediction of ecological speciation that the strength of premating isolation among species is predicted by phenotypic rather than genetic distance. We conducted mate choice experiments between three closely related, sympatric species of a recent radiation in Lake Mweru (Zambia/DRC) that differ in habitat use and phenotype, and a distantly related population from Lake Bangweulu that resembles one of the species in Lake Mweru. We found significant assortative mating among all closely related, sympatric species that differed phenotypically, but none between the distantly related allopatric populations of more similar phenotype. Phenotypic distance between species was a good predictor of the strength of premating isolation, suggesting that assortative mating can evolve rapidly in association with ecological divergence during adaptive radiation. Our data also reveals that distantly related allopatric populations that have not diverged phenotypically, may hybridize when coming into secondary contact, e.g. upon river capture because of diversion of drainage systems.

Is lean body mass decreased after obesity treatment by adjustable gastric banding?

BACKGROUND: There is concern that surgically-induced weight loss in obese subjects is associated with a disproportionate decrease in lean body mass (LBM) and in skeletal muscle mass (SMM), a major constituent of LBM. To address this issue, 1) we measured total and regional body composition following gastric banding in a group of obese subjects, and 2) we compared these data to those of a non-surgical control group of similar age and body size. METHODS: Body composition was assessed by dual-energy X-ray absorptiometry (DEXA) before and after laparoscopic adjustable silicone gastric banding (LAGB) in 32 women (after 1 year: age 43.7+/-8.4 years, BMI 36.4+/-5.9 kg/m2, mean+/-SD), and in 117 control women (age 44.5+/-7.5 years; BMI 36.7+/-5.5 kg/m2) referred for non-surgical weight management, prior to weight loss. SMM was estimated using a published equation based on LBM of the extremities (appendicular LBM). RESULTS: 1 year after LAGB, body weight loss (-23.7+/-11.6 kg, P<10(-6)) was mainly due to decreased fat mass (-21.2+/-11.2 kg, P<10(-6)), and total LBM was modestly, although significantly, decreased (-2.1+/-4.2 kg, P=0.01). Appendicular LBM (-0.7+/-2.7 kg) and total SMM (-0.9+/-3.0 kg) were not significantly modified. None of the body composition variables was significantly decreased in weight-reduced subjects compared to the control group, especially appendicular LBM and total SMM. CONCLUSIONS: Results provide no evidence for a decrease in appendicular LBM and total SMM with weight loss following LAGB. Follow-up of these obese patients revealed a very favorable pattern of change in total and regional body composition, with preservation of muscle mass.

Testing advances in molecular discrimination among Chinook salmon life histories: evidence from a blind test.

The application of DNA-based markers toward the task of discriminating among alternate salmon runs has evolved in accordance with ongoing genomic developments and increasingly has enabled resolution of which genetic markers associate with important life-history differences. Accurate and efficient identification of the most likely origin for salmon encountered during ocean fisheries, or at salvage from fresh water diversion and monitoring facilities, has far-reaching consequences for improving measures for management, restoration and conservation. Near-real-time provision of high-resolution identity information enables prompt response to changes in encounter rates. We thus continue to develop new tools to provide the greatest statistical power for run identification. As a proof of concept for genetic identification improvements, we conducted simulation and blind tests for 623 known-origin Chinook salmon (Oncorhynchus tshawytscha) to compare and contrast the accuracy of different population sampling baselines and microsatellite loci panels. This test included 35 microsatellite loci (1266 alleles), some known to be associated with specific coding regions of functional significance, such as the circadian rhythm cryptochrome genes, and others not known to be associated with any functional importance. The identification of fall run with unprecedented accuracy was demonstrated. Overall, the top performing panel and baseline (HMSC21) were predicted to have a success rate of 98%, but the blind-test success rate was 84%. Findings for bias or non-bias are discussed to target primary areas for further research and resolution.

Limerick Seed to Plate

The aim of the project is to address an identified need in the community, promoting healthy eating and organic home-gardening practices. Building on the success of a pilot intergenerational project entitled "Through the Years", it became apparent that gardening related activities could be implemented and promoted on a larger scale, reaching the wider community, groups and classes. The project serves as a setting for community education and will be inclusive in helping reduce isolation by providing meeting places for all members of their local communities. Key people being targeted are older people, local families and residents, Limerick Youth Service, After School Clubs, the Garda Youth Diversion Project and the Family Resource Centre. The Limerick Seed to Plate works with gardeners whose primary focus is to develop the gardening projects further. There is a strong educational emphasis to the project and the learning is transferred to participants own homes and lifestyles. Southill has a community café and, where possible, food grown in their garden is showcased and cooked in the centre and café. The Community Food Initiative strengthens the existing healthy eating habits in the community and aims to result in increased long-term health benefits arising from a healthier lifestyle. Communities will benefit from the project which will create employment, build bridges between communities, promote social inclusion and provide a focus for the local areas. Part of theDemonstration Programme 2010-2012 Location Limerick Target Groups At risk youth Children ( 4-12 years) Children (0-4 years) Children (13-18 years) Families Lone parents Low income families Men Migrant, minority ethnic groups Older people Travellers Unemployed Women

Gastric banding induces negative bone remodelling in the absence of secondary hyperparathyroidism: potential role of serum C telopeptides for follow-up.

OBJECTIVE: Data about the consequences of laparoscopic adjustable gastric banding (LAGB) on phospho-calcic and bone metabolism remain scarce. SUBJECTS: We studied a group of 37 obese premenopausal women (age: 24-52 y; mean BMI = 43.7 kg/m2) who underwent LAGB. METHODS: Serum calcium, phosphate, alkaline phosphatase, parathormone (PTH), vitamin D3, serum C-telopeptides, IGFBP-3 and IGF-1 were measured at baseline, 6, 12, 18 and 24 months after surgery. Body composition, bone mineral content (BMC) and density (BMD) were measured using dual-X-ray absorptiometry (DXA) at baseline, 6, 12 and 24 months after surgery. RESULTS: There was no clinically significant decrease of calcemia; PTH remained stable. Serum telopeptides increased by 100% (P < 0.001) and serum IGFBP-3 decreased by 16% (P < 0.001) during the first 6 months, and then stabilized, whereas IGF-1 remained stable over the 2 y. BMC and BMD decreased, especially at the femoral neck; this decrease was significantly correlated with the decrease of waist and hip circumference. CONCLUSIONS: We concluded that there was no evidence of secondary hyperparathyroidism 24 months after LAGB. The observed bone resorption could be linked to the decrease of IGFBP-3, although this decrease could be attributable to other confounding factors. Serum telopeptides seem to be a reliable marker of bone metabolism after gastric banding. DXA must be interpreted cautiously during major weight loss, because of the artefacts caused by the important variation of fat tissue after LAGB.

La reincidencia en el programa de mediación y reparación de menores

El estudio actualiza la tasa de reincidencia de los jóvenes que realizaron un programa de mediación i reparación penal juvenil en el año 2008 y a los que se siguió hasta el 30 de junio de 2011 para saber si habían vuelto a reincidir en algún delito, ya fuese como menores o como adultos. Se exponen los resultados tanto del perfil general de los menores, como de las características de los que son reincidentes. El estudio compara también esta intervención con otras medidas o programas como la amonestación, la aplicación del artículo 27.4 de la LORPM 5/2000 de no continuar tramitando el expediente, o las propuestas del equipo técnico respecto a imponer una medida de prestación en beneficio de la comunidad.

El temps en la justícia de menors

La recerca es proposa conèixer el temps objectiu que triga el sistema penal juvenil a donar resposta a les conductes presumptament delictives dels joves que hi arriben. L’interès per comptabilitzar i analitzar aquest temps de resposta del sistema penal juvenil es basa en dos motius: el primer és conèixer la incidència que té el temps en l’eficiència del sistema, eficiència que se sol associar al fet que es resolguin els assumptes amb agilitat. El segon motiu té a veure amb l’eficàcia de la pena o de la resposta que l’infractor pugui rebre. Des de l’àmbit penal i criminològic diversos autors, citats en la recerca, assenyalen que una resposta més ràpida fa la pena més eficaç. La recerca ha estudiat 8.059 procediments oberts a Catalunya l’any 2008 a joves infractors i en dona dades de la durada segons algunes variables (referides a les característiques dels joves, als fets delictius, al tipus de resolució, al territori que l’ha gestionat, als casos en els que s’ha fet mediació i reparació de menors, etc.). En els casos que ha estat possible, també s’ha fet una comparació entre l’any d’estudi (2008) i un any de control (2005) per saber quines han estat les diferències. Aquesta és la primera recerca que es publica a Catalunya sobre el total de temps que triga la justícia penal a donar resposta a una infracció presumptament comesa per un menor.

Phytobezoar by aloe vera as long term complication after oesophagectomy resolved using cellulase.

Bezoars are uncommon diseases caused by the presence of indigestible mass of strange material in the gastrointestinal tract. Gold-standard treatment remains unclear and there are not clinical guidelines to follow. We present a very rare case of 53-year-old man suffering phytobezoar in a gastroplasty after oesophagectomy due to aloe vera ingestion as natural medicine. Finally it was solved with cellulase. Therefore, this is a scarcely complication after esophagectomy. Cellulase is a very good option to treat phytobezoar avoiding reintervention in this kind of patient.

Intestinal gluconeogenesis is a key factor for early metabolic changes after gastric bypass but not after gastric lap-band in mice.

Unlike the adjustable gastric banding procedure (AGB), Roux-en-Y gastric bypass surgery (RYGBP) in humans has an intriguing effect: a rapid and substantial control of type 2 diabetes mellitus (T2DM). We performed gastric lap-band (GLB) and entero-gastro anastomosis (EGA) procedures in C57Bl6 mice that were fed a high-fat diet. The EGA procedure specifically reduced food intake and increased insulin sensitivity as measured by endogenous glucose production. Intestinal gluconeogenesis increased after the EGA procedure, but not after gastric banding. All EGA effects were abolished in GLUT-2 knockout mice and in mice with portal vein denervation. We thus provide mechanistic evidence that the beneficial effects of the EGA procedure on food intake and glucose homeostasis involve intestinal gluconeogenesis and its detection via a GLUT-2 and hepatoportal sensor pathway.

The prosecution service function within the spanish criminal justice system

The Spanish judicial system is independent and headed by the Supreme Court. Spain has a civil law system. The criminal procedure is governed by the legality principle--by opposition to the opportunity or expediency principle--which implies that prosecution must take place in all cases in which sufficient evidence exists of guilt. Traditionally, the role of the PPS in Spain has been very limited during the investigative stage of the process. That stage is under the responsibility of the Examining Magistrate (EM). Since the end of the 1980s, a series of modifications has been introduced in order to extend the functions of the PPS. In 1988, the PPS received extended competences which allow them to receive reports of offenses. Upon knowing of an offense (reported or known to have been committed), the PPS can initiate the criminal proceeding. The PPS is also allowed to lead a sort of plea bargain under a series of restrictive conditions and only for some offenses. At the same time, the PPS received extended competences in the juvenile justice criminal proceeding in 2000. With all this said, the role of the PPS has not changed radically and, during the investigative stage of the process, their main role remains the presentation of the accusation, playing a more active role during the trial stage of the proceeding. In this article the national criminal justice system of Spain is described. Special attention is paid to the function of the PPS within this framework and its relationship to police and courts. The article refers to legal provisions and the factual handling of criminal cases.

El tiempo en la justicia de menores

Este estudio aporta datos sobre el tiempo objetivo que tarda el sistema penal juvenil en dar respuesta a las conductas presuntamente delictivas de los jóvenes que llegan al sistema. El interés por contar y analizar este tiempo de respuesta del sistema penal juvenil se basa en dos justificaciones: la primera es conocer la incidencia que tiene el paso del tiempo en la eficiencia del sistema, eficiencia que se suele asociar al hecho que se resuelvan los casos con rapidez. El segundo motivo tiene que ver con la eficacia de la pena o de la respuesta que el infractor pueda recibir. Desde el ámbito penal y criminológico diversos autores, citados en la investigación, señalan que una respuesta más rápida hace la pena más eficaz. La investigación ha estudiado 8.059 procedimientos abiertos en Catalunya el año 2008 a jóvenes infractores y da datos respecto la duración según algunas variables (referidas a las características de los jóvenes, los hechos delictivos, el tipo de resolución, el territorio que la ha gestionado, los casos en los que se ha realizado una mediación y reparación de menores, etc.). En los casos que ha sido posible, también se ha realizado una comparación entre el año de estudio (2008) y un año de control (2005), para conocer cuales han sido estas diferencias. Es la primera investigación que se publica en Catalunya sobre el total de tiempo que tarda la justicia penal en dar respuesta a una infracción presuntamente cometida por un menor.

Opioid maintenance therapy in Switzerland: an overview of the Swiss IMPROVE study.

BACKGROUND/AIMS: Switzerland's drug policy model has always been unique and progressive, but there is a need to reassess this system in a rapidly changing world. The IMPROVE study was conducted to gain understanding of the attitudes and beliefs towards opioid maintenance therapy (OMT) in Switzerland with regards to quality and access to treatment. To obtain a "real-world" view on OMT, the study approached its goals from two different angles: from the perspectives of the OMT patients and of the physicians who treat patients with maintenance therapy. The IMPROVE study collected a large body of data on OMT in Switzerland. This paper presents a small subset of the dataset, focusing on the research design and methodology, the profile of the participants and the responses to several key questions addressed by the questionnaires. METHODS: IMPROVE was an observational, questionnaire-based cross-sectional study on OMT conducted in Switzerland. Respondents consisted of OMT patients and treating physicians from various regions of the country. Data were collected using questionnaires in German and French. Physicians were interviewed by phone with a computer-based questionnaire. Patients self-completed a paper-based questionnaire at the physicians' offices or OMT treatment centres. RESULTS: A total of 200 physicians and 207 patients participated in the study. Liquid methadone and methadone tablets or capsules were the medications most commonly prescribed by physicians (60% and 20% of patient load, respectively) whereas buprenorphine use was less frequent. Patients (88%) and physicians (83%) were generally satisfied with the OMT currently offered. The current political framework and lack of training or information were cited as determining factors that deter physicians from engaging in OMT. About 31% of OMT physicians interviewed were ≥60 years old, indicating an ageing population. Diversion and misuse were considered a significant problem in Switzerland by 45% of the physicians. CONCLUSION: The subset of IMPROVE data presented gives a present-day, real-life overview of the OMT landscape in Switzerland. It represents a valuable resource for policy makers, key opinion leaders and drug addiction researchers and will be a useful basis for improving the current Swiss OMT model.

Development of the Iowa Drainage Law Manual, March 2005

Although Iowa has some of the most productive agricultural land in the nation, it also maintains a very extensive road network.Consequently, landowners and roadway officials often must deal with drainage issues affecting private lands and public highways. However, many individuals are unfamiliar with legal drainage requirements, practices, and procedures, which can result in misunderstandings concerning maintenance responsibilities for drainage facilities, sometimes leading to litigation. To assist propertyowners, public agencies, and others with interest in better understanding drainage maintenance responsibilities, a reference manual was developed to describe Iowa’s drainage laws and offer interpretations in a clear and concise manner. To develop a comprehensive drainage manual, researchers identified and reviewed current available literature. These resources described pertinent drainage issues and presented explanations of legal responsibilities. The literature review included manuals and guides from Iowa, surrounding states, and federal agencies. Researchers developed a survey to assess the needs and interestsof potential users of an Iowa drainage law manual. Survey responses were used to identify common problems and concerns among individuals who encounter drainage issues on a regular basis. Issues mentioned in the survey responses included interpretation of drainage laws and commonly encountered questions relating to public improvements and private interests. Many individuals, including county engineers, stated interest in specific topics such as maintenance and/or diversion of drainage, landowner issues, and upstream and downstream impacts. Overall, the survey provided researchers with valuable information regarding drainage issues, problems, current policies, and concerns. A comprehensive manual of Iowa drainage law will assist agencies and individuals in interpreting current code requirements and in implementing effective and beneficial solutions when dealing with drainage issues.
