[Prognostic factors of pregnancy in intrauterine insemination].

BACKGROUND The artificial insemination is the introduction of spermatozoa in the feminine genital tract without carrying out sexual contact and with the purpose of obtaining the pregnancy. The insemination intrauterine has improved its rate of success thanks to the technological advances and the best knowledge of human reproductive physiology. OBJECTIVES To evaluate the prognostic factors for the pregnancy success and calculate the cumulative rate per cycle in IUI (intrauterine insemination). PATIENTS AND METHODS This study was descriptive, retrospective, analytic, and longitudinal. The cycles of IUI were analyzed from January 1st 2003 to December 31st 2005. Couples 24-41 years old with primary and secondary infertility were included. The following variables were studied: age of participant, type of infertility, length of infertility, aetiology, postcapacitation sperm density and motility, number of follicles, endometrial thickness, and the cycle number in which the IUI was performed. Patients carried out a protocol of ovarian stimulation and follicular follow up. The results were analyzed with 11.0 SPSS, continuous variables were analyzed and reported as means +/- SD with univariate logistic regression to determine statistic significance. Categoric variables were reported in frequencies and percentages. ROC curves were calculated to determine optimal cutting points. RESULTS 668 cycles were analyzed in 391 couples. The pregnancy rate per cycle and couple was of 13.0 and 21.7% respectively. Means +/- SD patient age was 33.5 +/- 3.4 years old. The three variables with p < 0.05 were: the infertility duration, sperm motility and the cycle number in which IUI was performed. No statistical significance was found in the remaining variables. CONCLUSIONS The greatest success in IUI will be achieved with infertility of 4 years or less, with sperm motility of 77.6% and in the first two cycles of treatment.
Comparison of Raindrop Size Distribution Estimates From X-Band and S-Band Polarimetric Observations

This letter evaluates the consistency of rainfall drop size distribution (DSD) parameters that were estimated from attenuation-corrected X-band dual-polarization (XPOL) radar measurements with estimates from a colocated S-band dual-polarization radar (S-Pol). The DSD retrieval technique uses reflectivity and differential reflectivity, and a constrained relationship to estimate the three parameters of a ldquonormalizedrdquo gamma distribution model. The more definitive S-Pol DSD parameter estimates are used as a reference to assess the performance of the corresponding XPOL estimates for different rain-path attenuation values. Results show that XPOL attenuation-corrected profiles can provide rainfall DSD estimations that are consistent to an S-band dual-polarization radar, even in cases of moderate to high rain-path attenuation.

DIAGNÓSTICO DE LA DEGRADACIÓN DE ALGUNOS SUELOS TABACALEROS DE LA EMPRESA LÁZARO PEÑA

Los suelos Ferraliticos Rojos se encuentran sometidos a un regimen de cultivo intensivo, que provoca alteraciones de sus propiedades quimicas y fisico-quimicas. El diagnostico de estos procesos degradativos, permite valorar su intensidad y disenar las medidas para su recuperacion. El trabajo se llevo a cabo en algunas UBPC de la Empresa Tabacalera Lazaro Pena, ubicada en el municipio San Antonio de los Banos. Tuvo como objetivo: determinar las caracteristicas quimicas y fisico-quimicas actuales en los suelos ferraliticos rojos tipicos, compactados e hidratados. Los resultados obtenidos mostraron una elevacion de los tenores de materia organica, contrario al criterio de que este cultivo tiende a empobrecerlos. Se observa un sustancial aumento de la relacion Ca/Mg, con valores promedios equivalentes a 11.78. Este fenomeno se puede relacionar con un incremento de los contenidos de calcio, por realizarse la actividad del riego con aguas ricas en este elemento. Intimamente relacionado esta el aumento del PH que supera el umbral de 7,5. Los valores de fosforo y potasio se comportan altos para todos los suelos analizados, debido a las fertilizaciones frecuentes realizadas en periodos anteriores. La practica de rotacion y alternancia de cultivos en los sistemas de produccion intensiva conducen al incremento de los tenores de materia organica en este recurso natural, contribuyendo a su mejoramiento y conservacion
Quantitation of calcium metabolism in postmenopausal osteoporosis and in scoliosis.

By a combination of balance and isotope techniques, the following parameters of Ca metabolism were measured: pool size, rate of loss from pool, urinary excretion, fecal excretion, intake, endogenous fecal Ca, absorption, balance, bone formation, and bone resorption. The subjects were two normal women and five women with postmenopausal osteoporosis, aged 41 to 74 years, and four patients with scoliosis, aged 12 to 22 years. The latter were studied before, shortly after, and many months after immobilization in plaster casts. On the basis of observed relationships, it appeared that the negative Ca balance observed in the older women was due to the low intensity of the various vectors of Ca metabolism, without clearcut distinction between the subjects with and without osteoporosis. Conversely, in the young patients with scoliosis, the negative balance incident to treatment by immobilization was associated with vectors of relatively high intensity whose relationships were altered temporarily.
Plasmid profiling of members of the family Enterobacteriaceae, lactobacilli, and bifidobacteria to study the transmission of bacteria from mother to infant

Plasmid profiles of isolates of the family Enterobacteriaceae, lactobacilli, and bifidobacteria cultured from vaginal, oral, and rectal swabs collected from women soon after admission to a maternity hospital were compared with those of strains detected in the feces of their infants. Lactobacilli inhabiting the vaginas of the mothers did not appear to colonize the infant digestive tract, but evidence for the transmission of fecal isolates of the Enterobacteriaceae and bifidobacteria from mother to infant was obtained in four out of five cases. Many of the bifidobacteria isolated were plasmid-free but could be distinguished with biochemical profiles.
In-Network Computation is a Dumb Idea Whose Time Has Come

Programmable data plane hardware creates new opportunities for infusing intelligence into the network. This raises a fundamental question: what kinds of computation should be delegated to the network? In this paper, we discuss the opportunities and challenges for co-designing data center distributed systems with their network layer. We believe that the time has finally come for offloading part of their computation to execute in-network. However, in-network computation tasks must be judiciously crafted to match the limitations of the network machine architecture of programmable devices. With the help of our experiments on machine learning and graph analytics workloads, we identify that aggregation functions raise opportunities to exploit the limited computation power of networking hardware to lessen network congestion and improve the overall application performance. Moreover, as a proof-of-concept, we propose Daiet, a system that performs in-network data aggregation. Experimental results with an initial prototype show a large data reduction ratio (86.9%-89.3%) and a similar decrease in the workers' computation time.

An Economic Approach for Generation of Train Driving Plans using Continuous Case-based Planning

We present an approach for reusing and sharing train driving plans P using continuous (or without human intervention) Case-Based Planning (CBP). P is formed by a set of actions, which when applied, can move a train in a stretch of railroad. This is a complex task due to the variations in the (i) composition of the train, (ii) environmental conditions, and (iii) stretches travelled. To overcome these difficulties we provide to the driver a support system to help the driver in this complex task. CBP was chosen because it allows directly reuse the human drivers experience as well as from other sources. The main steps of the CBP are distributed among specialized agents with different roles: Planner and Executor. Our approach was evaluated by different metrics: (i) accuracy of the case recovery task, (ii) efficiency of task adaptation and application of such cases in realistic scenarios and (iii) fuel consumption. We show that the inclusion of new experiences reduces the efforts of both the Planner and the Executor, reduces significantly the fuel consumption and allow the reuse of the obtained experiences in similar scenarios with low effort.
Human Immunodeficiency Virus Type 1 Virological Synapse Formation in T Cells Requires Lipid Raft Integrity

ABSTRACT Human immunodeficiency virus type 1 (HIV-1) can spread directly between T cells by forming a supramolecular structure termed a virological synapse (VS). HIV-1 envelope glycoproteins (Env) are required for VS assembly, but their mode of recruitment is unclear. We investigated the distribution of GM1-rich lipid rafts in HIV-1-infected (effector) T cells and observed Env colocalization with polarized raft markers GM1 and CD59 but not with the transferrin receptor that is excluded from lipid rafts. In conjugates of effector T cells and target CD4+ T cells, GM1, Env, and Gag relocated to the cell-cell interface. The depletion of cholesterol in the infected cell dispersed Env and GM1 within the plasma membrane, eliminated Gag clustering at the site of cell-cell contact, and abolished assembly of the VS. Raft integrity is therefore critical for Env and Gag coclustering and VS assembly in T-cell conjugates.

CONCRETE SCALING – A CRITICAL REVIEW

Scaling, i.e., local flaking or peeling away of the near-surface portion of a concrete slab is the most common type of surface distress, especially in areas exposed to cyclic freezing and thawing, and deicing chemicals. A comprehensive evaluation of factors responsible for concrete surface scaling is presented. The article gives a close look to the influences of: (a) concrete materials, proportions, and properties (air content, air void system, aggregate, cement paste, aggregate-paste interface, compressive strength, water-cementitious materials ratio, degree of saturation of concrete, and chemical admixtures); (b) construction practices (consolidation, finishing, curing, hot and cold weather protections, drainage, and surface treatments); (c) concrete maturity; and (d) deicing salts (salt type, concentration, timing of exposure) on scaling. The evaluation is based on numerous case studies on field reconnaissance and laboratory investigation of concrete scaling, where holistic approaches incorporating all possible factors for scaling were considered. The results show that in a cyclic freezing and thawing environment, the most common causes of scaling are related to one or a combination of the following factors: (a) poor quality of concrete (e.g., having no or low air content, poor air-void system, unsound aggregates, etc.), (b) improper construction practices (e.g., improper finishing, inadequate curing), (c) exposure to corrosive (e.g., magnesium or ammonium-based) salts, (d) exposure to the common sodium or calcium chloride based salts at an early age prior to the attainment of maturity, and (e) exposure of an inherently poor quality and/or poorly constructed concrete to deicing salts. Surface scaling in an apparently non-freezing environment can occur by improper finishing practices or, by reversible phase transformations of soluble salts (e.g., of sodium sulfate or carbonate) and zeolites (e.g., laumontite) between less-hydrous (or anhydrous) and more hydrous states during cyclic wetting and drying. Fulfilling the common industry recommendations, e.g., of air content, compressive strength, and water-cementitious materials ratio may not necessarily guarantee the necessary scaling resistance unless a comprehensive evaluation of the influences of all possible factors related to concrete mixture, construction practices, and the environment on scaling are exercised, and, the concrete is accordingly designed, placed, finished, cured, and matured for the maximum durability.

Taxonomic classification of metagenomic sequences

Bacteria, archaea and microeukaryotes can be found in almost every habitat present in nature, in particular in soil, sediments and sea water. They typically live in complex communities with different kinds of symbiotic associations which include relationships with larger organisms like animals or plants. Examples are microbial communities in the gut or on the skin of animals and humans, or bacteria that live in symbiosis with plants. The vast majority of such microbes are unculturable and thus cannot be sequenced by means of traditional methods. The recently upcoming discipline of metagenomics provides various in vivo- and in silico-tools to overcome this limitation. In particular, high-throughput sequencing techniques like 454 or Solexa-Illumina make it possible to explore those microbes by studying whole natural microbial communities and analysing their biological diversity as well as the underlying metabolic pathways. A current limitation of theses technologies is that they can sequence only DNA fragments of a limited length. With this limitation it is usually not possible to recover complete microbial genomes. In addition, the DNA fragments are drawn randomly from the microbial communities and the exact species of origin is unknown. Over the past few years, different methods have been developed for the taxonomic and functional characterization of metagenomic shotgun sequences. However, the taxonomic classification of metagenomic sequences from novel species without close homologues in the biological sequence databases poses a challenge due to the high number of wrong taxonomic predictions on lower taxonomic ranks. In this thesis we present CARMA3, a novel method for the taxonomic classification of assembled and unassembled metagenomic sequences that has been adapted to work with both BLAST and HMMER3 homology searches. CARMA3 accepts protein-encoding DNA sequences, protein sequences, and 16S-rDNA sequences as input. In addition, we present WebCARMA, a web application for the analysis of protein-encoding DNA sequences with CARMA3 without the need for a local installation. We evaluate our novel method in different experiments using simulated and real shotgun metagenomes and show that CARMA3 makes fewer wrong taxonomic predictions (at the same sensitivity) than other BLAST-based methods. In the last experiment we show that also very short reads can, in principle, be used to describe the taxonomic content of a metagenome.
SOI Pixel Based on a Floating Body Partially Depleted MOSFET in a Delta-Sigma Loop

Standard techniques used for measuring the photocurrent of an SOI phototransistor have failed due to two main reasons: the first being the low signal-to-noise ratio and the second being the slow transient. In this paper, the partially depleted silicon on insulator (SOI) metal-oxide-semiconductor field effect transistor (MOSFET) has been used as a light intensity sensor. Using a novel technique of measurement enables us to embed this phototransistor in the delta-sigma loop. The presented circuits implement a first-order delta-sigma modulator with limited number of transistors maximizing the fill factor. Measured data show that the implemented pixels were sensitive to flux densities as low as 3 mW/m2 with a resolution of 7.5 bits.
Conformational changes in the 20S proteasome upon macromolecular ligand binding analyzed with monoclonal antibodies.

Proteasomes interact with a variety of macromolecular ligands that modulate their ability to degrade peptide and protein substrates. The effector PA28 increases the peptidase activities of proteasomes whereas HSP90 and alpha-crystallin inhibit a peptide-hydrolyzing activity. Four monoclonal antibodies were used as probes to detect conformational changes of proteasome subunits. Conformational changes in alpha- or beta-subunits were found upon binding PA28, HSP90, alpha-crystallin, and the substrate casein but not with the peptide substrate analogs calpain inhibitor 1 (Ac-Leu-Leu-norleucinal), calpain inhibitor 2 (Ac-Leu-Leu-methioninal), or MG 132 (N-Cbz-Leu-Leu-leucinal).
Assessing The Factors That Have An Impact On Stickiness In Online Game Communities

How to attract players has been of interest to practitioners, online game designers and game site constructors. The objective of this research is to explore factors that effect stickiness in online game communities. This study applies social cohesion theory, social identity theory and motivational theory to propose a research model. Structural equation modeling results indicate that stickiness is influenced by social cohesion, playfulness and habit. In addition, social identification, social need and offline social interaction have a significant impact on social cohesion. Practical implications and limitations are also discussed.
Malrotation of the Intestine in Children

Intestinal malrotation may be complicated by volvulus and intestinal necrosis. One hundred two children (64 male, 38 female) undergoing surgical abdominal exploration from 1977 to 1987 had malrotation. Fifty-two patients were less than 7 days of age, 13 from 8 to 30 days, 26 from 31 to 365 days, and 11 were older than 1 year of age. Of infants, 39 of 65 had 40-week gestations, 18 of 65 had 36− to 39-week gestations, and 8 of 65 had less than 36-week gestations. Chief symptomatology included: bilious emesis (47), intestinal obstruction (19), abdominal pain (11), and bloody stools (7). Seventy patients had congenital anomalies (50 single, 20 multiple). Diagnostic evaluations included 56 upper gastrointestinal series and 27 barium enemas. Each patient underwent correction of malrotation and appendectomy, and correction of congenital anomalies (omphalocoele—9, gastros-chisis—6, diaphragmatic hernia—7). Complications included short gut (2), sepsis (5), feeding difficulties (2), pneumonia (3), small bowel obstruction (2), and other (15). Nine patients (8.8%) died (trisomy 18—1, trisomy 13—1, intestinal necrosis—3, hepatic failure—1, prematurity—1, other sepsis—2). Two hundred sixteen children with intestinal malrotation have been treated from 1937 to 1987. Mortality rate has improved from 23% to 2.9%.
Power system tracking and dynamic state estimation

State estimation is a key Energy Management System (EMS) function, responsible for estimating the state of the power system. Since state estimation is computationally expensive, it is not easy to execute it repetitively at short intervals, which is a requirement for real time monitoring and control. Hence in order to obtain a computationally inexpensive real time update of the state vector, tracking state estimation algorithms have been proposed and discussed in various research papers available in the literature. Tracking state estimation provides a fast real time update on the state of the power system with out any physical modeling of the time varying nature of the system. Dynamic state estimation models the time varying nature of the system, which allows it to predict the state vector in advance. Hence proves to be a major advantage in security analysis and other control functions. Various techniques for tracking and dynamic state estimation are available in the literature. This paper presents a bird's view on different methodologies and developments in both of these techniques based on our comprehensive survey of the available literature.
