Accuracy of five different diagnostic techniques in mild-to-moderate pelvic inflammatory disease.

OBJECTIVE: To evaluate the clinical diagnosis of pelvic inflammatory disease (PID) compared with the diagnosis of PID made by laparoscopy, endometrial biopsy, transvaginal ultrasound, and cervical and endometrial cultures. Study design: A diagnostic performance test study was carried out by cross-sectional analysis in 61 women. A group presenting PID (n = 31) was compared with a group (n = 30) presenting another cause for non-specific lower abdominal pain (NSLAP). Diagnosis provided by an evaluated method was compared with a standard diagnosis (by surgical findings, histopathology, and microbiology). The pathologist was unaware of the visual findings and presumptive diagnoses given by other methods. RESULTS: All clinical and laboratory PID criteria showed low discrimination capacity. Adnexal tenderness showed the greatest sensitivity. Clinical diagnosis had 87% sensitivity, while laparoscopy had 81% sensitivity and 100% specificity; transvaginal ultrasound had 30% sensitivity and 67% specificity; and endometrial culture had 83% sensitivity and 26% specificity. CONCLUSIONS: Clinical criteria represent the best diagnostic method for discriminating PID. Laparoscopy showed the best specificity and is thus useful in those cases having an atypical clinical course for discarding abdominal pain when caused by another factor. The other diagnostic methods might have limited use

Evaluación de estructuras MIMO sobre tecnología LTE de cuarta generación (4G) de telefonía móvil

The project started toward the realization of a software component for the simulation of an LTE system that would allow the evaluation of diversity and MIMO multiplexing structure. The OFDM modulation for downlink set was used with MIMO structures for implementation in each of its etapas.Se evaluated the system's ability to reduce the effects of canalrepresentado in Rayleigh fading type, typical of a frequency selective system . This evaluation was performed through the bit error rate ( VER) versus the signal to noise ratio (SNR). In this way it was possible to quantify the effect that different antenna arrays on system performance , including structures MIMO that are outside the current standards of LTE technology and give a valuable contribution in terms of certain conditions performance    El proyecto se  encamino hacia la realizacion de un componente de software para la simulacion de un sistema LTE que permitiera la evaluacion de estructura MIMO de diversidad y multiplexacion. La modulacion OFDM establecida para el enlace descendente fue la utilizada junto a las estructuras MIMO para su implementacion en cada una de sus etapas.Se evaluo la capacidad del sistema para reducir los efectos del canalrepresentado en desvanecimientos tipo Rayleigh, tipico de un sistema selectivo  en frecuencia. Esta evaluacion se realizo a traves de la tasa de error de bit (VER) versus la relacion señal a ruido (SNR). De esta forma se pudo cuantificar el efecto que tienen los diferentes arreglos de antenas sobre el rendimiento del sistema, incluyendo estructuras MIMO que se encuentran fuera de los estandares actuales de la tecnologia LTE y que dan un aporte valioso en cuanto al rendimiento bajo determinadas condiciones

Retinoic acid reduces migration of human breast cancer cells: role of retinoic acid receptor beta

Breast cancer is the most common malignancy in women and the appearance of distant metastases produces the death in 98% of cases. The retinoic acid receptor b (RARb) is not expressed in 50% of invasive breast carcinoma compared with normal tissue and it has been associated with lymph node metastasis. Our hypothesis is that RARb protein participates in the metastatic process. T47D and MCF7 breast cancer cell lines were used to perform viability assay, immunobloting, migration assays, RNA interference and immunofluorescence. Administration of retinoic acid (RA) in breast cancer cells induced RARb gene expression that was greatest after 72 hrs with a concentration 1 lM. High concentrations of RA increased the expression of RARb causing an inhibition of the 60% in cell migration and significantly decreased the expression of migration-related proteins [moesin, c-Src and focal adhesion kinase (FAK)]. The treatment with RARa and RARc agonists did not affect the cell migration. On the contrary, the addition of the selective retinoid RARb-agonist (BMS453) significantly reduced cell migration comparable to RA inhibition. When RARb gene silencing was performed, the RA failed to significantly inhibit migration and resulted ineffective to reduce moesin,c-Src and FAK expressions. RARb is necessary to inhibit migration induced by RA in breast cancer cells modulating the expression of proteins involved in cell migration.Fil: Flamini, Marina Ines.

The Effect of Adding Zeolite in the Feed of Chickens Cobb 500

[EN] The objective of this study was to evaluate the effects of the addition of zeolite on the feeding of Cobb 500 chickens in the productive parameters. The work was carried out in an integral farm of Ecuador, adopting the standards of biosafety and animal welfare for the breeding of poultry; no vaccines or drugs were administered. 200 chickens (1-day old) were studied for 42 days and distributed in 5 treatments, each one with 4 replicates (10 chickens per replicate, randomly selected); the treatments were: T1(control), T2(zeolite 2%), T3(zeolite 3%), T4(zeolite 4%) and T5(zeolite 5%). All of the groups were fed with BALMAR, a commercial feed (Pre-initial: 22.56% CP, 3150 Kcal/kg ME; initial: 21% CP, 3200 Kcal/kg ME; grow-out: 19.5% CP, 3250 Kcal/Kg ME), T1 included a commercial toxin trapper, for all other groups zeolite was added as a substitute for the commercial toxin trap. The variables studied were: feed and water consumption, feed conversion ratio, live weight and mortality. The data were processed with the statistical program Stat graphics Centurion XV.I, by means of ANOVA analysis. The results of this experiment showed that there were no significant statistical differences in water consumption, food intake and feed conversion when comparing the treatments with the control, although, the final weight showed statistical difference (p<0.05). The highest mortality was recorded in T1 (12.5%). It is concluded that at higher zeolite increase, better effects, thus the live weight of T5 (1638.9±46.7) was statistically similar to the control (1734.3±49.3); water and feed consumption and feed conversion rate were not affected; possibly the reduction in mortality was due to the toxins trapping action of zeoliteSanchez-Quinche, AR.; Pindo Nagua, FM.; Vargas González, ON.; Alvarez Díaz, CA.; Aguilar Galvez, LF.; Pérez Baena, I.

Potential group B Streptococcus interspecies transmission between cattle and people in Colombian dairy farms

Group B Streptococcus (GBS), is a leading cause of neonatal death and an emerging pathogen in adults. Additionally, GBS is a bovine pathogen causing intramammary infections. The likelihood of GBS interspecies transmission is largely unknown. We explored the potential transmission of GBS between cattle and people on dairy farms in Colombia and compared the antimicrobial resistance (AMR) profiles of isolates from both host species. Across 33 farms, throat swabs and rectal swabs were collected from 191 people, and rectal swabs and composite milk samples from 2092 cattle, yielding 60 human isolates and 301 bovine isolates. The majority (64%) of isolates belonged to shared sequence types (ST). Sequence type (ST) 1 was the most common strain in both host species, suggesting that interspecies transmission may be possible. Two members of the bovine-specific clonal complex 61/67 were detected in human samples (ST718 and ST1175), providing evidence for the lack of genuine species barriers. Apparent prevalence of penicillin resistance was surprisingly high in human and bovine isolates. Further investigation of this phenomenon is needed and could lead to modification of standard testing and treatment recommendations in human and veterinary medicine

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper. DR14 happened on 31st July 2017. 19 pages, 5 figures.

Development of a Panel of Genome-Wide Ancestry Informative Markers to Study Admixture Throughout the Americas

Most individuals throughout the Americas are admixed descendants of Native American, European, and African ancestors. Complex historical factors have resulted in varying proportions of ancestral contributions between individuals within and among ethnic groups. We developed a panel of 446 ancestry informative markers (AIMs) optimized to estimate ancestral proportions in individuals and populations throughout Latin America. We used genome-wide data from 953 individuals from diverse African, European, and Native American populations to select AIMs optimized for each of the three main continental populations that form the basis of modern Latin American populations. We selected markers on the basis of locus-specific branch length to be informative, well distributed throughout the genome, capable of being genotyped on widely available commercial platforms, and applicable throughout the Americas by minimizing within-continent heterogeneity. We then validated the panel in samples from four admixed populations by comparing ancestry estimates based on the AIMs panel to estimates based on genome-wide association study (GWAS) data. The panel provided balanced discriminatory power among the three ancestral populations and accurate estimates of individual ancestry proportions (R2>0.9 for ancestral components with significant between-subject variance). Finally, we genotyped samples from 18 populations from Latin America using the AIMs panel and estimated variability in ancestry within and between these populations. This panel and its reference genotype information will be useful resources to explore population history of admixture in Latin America and to correct for the potential effects of population stratification in admixed samples in the region
