The Complete Genome Sequences of 3 Species of Fishes (Labrisomidae, Blenniiformes).

We present the complete genome sequences of Malacoctenus gilli, Malacoctenus tetranemus, Malacoctenus triangulates. Illumina sequencing was performed on genetic material from museum specimens. The reads were assembled using a de novo method followed by a finishing step.

The Complete Genome Sequences of 7 Hypoplectrus species (Serranidae, Perciformes).

Species in the genus are found primarily in coral reefs in the Caribbean Sea and the Gulf of Mexico, particularly around Florida and the Bahamas. They are a popular choice for hobbyist saltwater aquariums. Members of this genus are simultaneous hermaphrodites, as they have both male and female sexual organs at the same time as an adult.

Review of the Pareques acuminatus (Bloch & Schneider, 1801) species complex, with revalidation of Pareques lineatus (Cuvier, 1830) from the Western Atlantic (Percomorphacea: Sciaenidae).

Recently, different studies have revealed the existence of complexes of marine fish species of several genera from the Western Atlantic (e.g., Bagre, Peprilus, Bairdiella, Pogonias and Menticirrhus), with a correspondence between recognized species and well-established geographic areas such as the Gulf of Mexico, the Caribbean, and Brazil, showing the need to improve the taxonomic knowledge of coastal fishes in the region.

Genomics overrules mitochondrial DNA, siding with morphology on a controversial case of species delimitation.

Species delimitation is a major quest in biology and is essential for adequate management of the organismal diversity. A challenging example comprises the fish species of red snappers in the Western Atlantic. Red snappers have been traditionally recognized as two separate species based on morphology: Lutjanus campechanus (northern red snapper) and L.

The Influence of Homophilous Interactions on Diversity Effects in Group Problem-Solving.

Increasingly diversity researchers call for further studies of group micro-processes and dynamics to understand the paradoxical effects of diversity on group performance. In this study, based on analyses of in-group, networked, homophilous interactions, we aim to explain further the effects of diversity on group performance in a parallel problem-solving task, both experimentally and computationally. We developed a 'whodunit' problem-solving experiment with 116 participants assigned to different-sized groups.

Phylogenetic classification of bony fishes.

Background: Fish classifications, as those of most other taxonomic groups, are being transformed drastically as new molecular phylogenies provide support for natural groups that were unanticipated by previous studies. A brief review of the main criteria used by ichthyologists to define their classifications during the last 50 years, however, reveals slow progress towards using an explicit phylogenetic framework. Instead, the trend has been to rely, in varying degrees, on deep-rooted anatomical concepts and authority, often mixing taxa with explicit phylogenetic support with arbitrary groupings.

Production of microbubbles from axisymmetric flow focusing in the jetting regime for moderate Reynolds numbers.

We analyze both experimentally and numerically the formation of microbubbles in the jetting regime reached when a moderately viscous liquid stream focuses a gaseous meniscus inside a converging micronozzle. If the total (stagnation) pressure of the injected gas current is fixed upstream, then there are certain conditions on which a quasisteady gas meniscus forms. The meniscus tip is sharpened by the liquid stream down to the gas molecular scale.

Nutritional composition and condensed tannin concentration changes as browse leaves become litter.

Background: The role of condensed tannins (CT) in ruminant nutrition and health makes changes in leaf litter (LL) after abscission of interest. This study compared the effect of different drying methods of green leaves (GL) with that of natural drying of LL on CT, fibre, crude protein (CP) and phosphorus (P) concentrations in nine Texas browse species. Leaves harvested before autumn shedding were oven-dried (OD) or freeze-dried (FD).

[Effect of herbivorous and corallivorous fishes on the survival of transplanted corals in the Colombian Caribbean].

To examine the effects of herbivorous and corallivorous fishes on the survival of transplanted colonies of Montastraea annularis, Diploria labyrinthiformis and Porites astreoides, both transplanted and native colonies were full-cage enclosed and compared to open (uncaged) colonies, while caging effects were assessed with a partial-cage (roof treatment). To evaluate if transplant stress increased the corals availability to fish predation, comparisons of fish foraging intensity among transplanted versus native colonies were made. To determine the density of herbivorous and corallivorous fishes on the transplants area visual censuses were made.

Advances in the biomedical applications of the EELA Project.

In the last years an increasing demand for Grid Infrastructures has resulted in several international collaborations. This is the case of the EELA Project, which has brought together collaborating groups of Latin America and Europe. One year ago we presented this e-infrastructure used, among others, by the biomedical groups for the studies of oncological analysis, neglected diseases, sequence alignments and computational phylogenetics.

In-Plane Structure of the Liquid-Vapor Interface of an Alloy: A Grazing Incidence X-ray Diffraction Study of Bismuth:Gallium.

The liquid-vapor interface of a bismuth-gallium mixture (0.2 percent bismuth and 99.8 percent gallium) at 36 degrees C has been studied by grazing incidence x-ray diffraction.

Skeletal muscle PO2 during hypoxemia and isovolemic anemia.

We subjected anesthetized mechanically ventilated rabbits (n = 6) to sequential exchanges of blood for a 6% dextran solution and compared their responses with those obtained in a previous study on progressive hypoxemia (n = 7). Right atrial PO2 (PVO2)RA and hindlimb PO2 (PVO2)limb, measured at the level of the iliac bifurcation, were compared with tissue PO2 (PtiO2) histograms obtained with an array of surface microelectrodes placed over the biceps femoris muscle. Systemic O2 consumption (VO2) was measured with the expired gas method.

Relationship of venous PO2 to muscle PO2 during hypoxemia.

Anesthetized mechanically ventilated rabbits were subjected to progressive hypoxemia (n = 7) to determine the relationship of venous PO2 (PvO2) to skeletal muscle PO2 (PtiO2). Measures of arterial PO2 (PaO2), right atrial PO2 [(PvO2)RA], and hindlimb PO2 [(PvO2)limb], were obtained from the carotid artery, right atrium, and inferior vena cava, just above the level of the iliac bifurcation. Biceps femoris muscle PtiO2 was measured with a surface O2 microelectrode having eight measuring points.

[Pulmonary scintigraphy using the inhalation of monodispersed radioactive aerosols. Preliminary report].

This article describes a method for inhalatory lung scintigraphy (ILS) by the use of radioactive monodisperse aerosols, with particles smaller than 2 microns. We discuss the findings in normal subjects, in patients with pulmonary embolism (PE) or/and obstructive pulmonary disease (OPD), and in individuals with severe pulmonary hypertension. This procedure has several advantages over the use of radioactive gases, such as 133Xe and 81Krm: lower cost, easier to perform, several scintigraphic projections in one study, acquisition of perfusion and inhalatory images in a single session, and inhalatory and perfusion images with identical spatial resolution and similar data density.

[Scintigraphic criteria for the diagnosis of pulmonary embolism].

The natural history of pulmonary embolism is described, together with the physiopathologic alterations and the clinical manifestations of this disease, correlating these with the various patterns of pulmonary perfusion usually found by lung scintigraphy with 99mTc-MAA in patients with thromboembolic lung disease. By using data found in the literature, the operating characteristics (sensitivity, specificity, and accuracy) and the predictive values of the different scintigraphic patterns, were calculated for populations with different prevalences of pulmonary embolism. It is concluded that perfusion lung scintigraphy is a non-invasive, objective and fast procedure, very sensitive to alterations of the regional blood flow, but that is not specific for embolism.

[Formation and migration of radioactive microemboli to the lung during radiovenography].

Two patients with lower extremity thrombophlebitis were studied by radionuclide venography with macroaggregated albumin labelled with 99mTc. Data analysis was performed with a new method. It generated sequential series of imagen (1-2 sec/frame) of the transit of the tracer through leg, thigh, and abdomen, allowing a more precise definition of temporal changes on regional radioactivity.

[Bayesian analysis of myocardial scintigraphy using 99mTc-Sn(II)-methylenediphosphonate and using 99mTc-Sn(II)-pyrophosphate].

Myocardial scintigraphy with 99mTc-Sn (II)-Methylenediphosphonate (MDP) and with 99mTc-Sn (II) pyrophosphate (PPi) was performed in 185 patients with proven acute myocardial infarction (90 with MDP; 95 with PPi), and in 65 subjects with acute chest pain of a different etiology (37 with MDP; 28 with PPi), during the first five days after the onset of illness. Sensitivity, specificity and accuracy of the procedure were higher with PPi (0.895, 0.

[Predictive value of 99m-Tc-Sn(II) methylene diphosphonate in the study of acute myocardial infarction].

Myocardial scintigraphy with 99mTc-Sn (II)-Methylenediphosphonate (MDP) was performed in 90 patients with proven acute myocardial infarction (AMI), and in 37 subjects with acute chest pain of a different etiology, during the first five days after the onset of their illness. The procedure was 82.2% sensitive, 86.

[Plasma cortisol response after stimulation with ACTH in postmature newborns (author's transl)].

Authors have studied, in three series of newborns-I) normal term: II) small for date, and III) postmature-, the basal levels of plasmatic cortisol and after stimulation with ACTH. Blood samples were obtained at the 48 hours and 10 days of life, respectively. There are not significative differences in the three groups neither in the basal levels of plasmatic cortisol nor after stimulation (p greater than 0.
