Beneficial Impression of San-ligation over High-ligation during Orchidopexy; a Cross-Sectional of 2659 Patients

Background The ligation of the patent processus vaginalis (PPV) is the challenging issue during the orchidopexy in the patients who suffering undescended testis (UDT). In the present study we aimed to comparing the advantages of the orchidopexy with high-ligation method and the san-ligation method as a modified orchidopexy in our more than 6 years` experiences. Materials and Methods The medical records of 2,659 boys with UDT who undergone orchidopexy in xx hospital, Qom-Iran, between February 2010 and October 2016 were analyzed. The exclusion criteria were consisting of critical cases, presence of concomitant obvious clinical hernia, re-operation due to re-ascending, abdominal UDT, and coincidence with other anomalies. Two surgical method were performed based upon the medical records: 1- orchidopexy with PPV high-ligation, and 2- orchidopexy with PPV san-ligation. Results A total of 2,659 medical records with 3,208 UDTs were reviewed. Of them, 2,210 (79.4%) patients had unilateral UDT. Of the total UDTs, 1,956 (61%) UDTs were located in the inguinal canal. The mean age of the patients was 21.3 ±2.7 months. Of the total UDTs, 2,187 (68.2%) and 1,021 (31.8%) were undergone orchidopexy with high-ligation and san-ligation PPV, respectively. The operative time significantly decreases in the san-ligation PPV group (11.2 minutes vs. 18.4 minutes; P =0.03). A total of 207 (6.45%) complications were occurred in the 187(7%) patients. The commonest complication was spermatic cord/testicular edema which was no significant difference in both surgical groups (P=0.769). Conclusion The modified orchidopexy with san-ligation of PPV does not significantly increase the risk of post-operative complications. However, this method significantly reduces the operative time.

Pattern of Haematological Malignancies in Ilorin, Nigeria: A Ten Year Review

A 10 year retrospective survey of haematological malignancies in Ilorin, Nigeria, was carried out based on data from the Records Department and the Cancer Registry of the Morbid Anatomy Department of the University of Ilorin Teaching Hospital.The aim was to determine the current pattern of haematological malignancies in the study area and compare with previous reports from other parts of Nigeria and worldwide.A total of 370 cases of haematological malignancies which were diagnosed within the study period (January 1996 to December 2005) by means of available haematological laboratory methods and histological examinations were analyzed. The distribution of the various haematological malignancies recorded were: ALL 18(4.9%), AML 18(4.9%), CLL 20(5.4%), CML 42(11.4%), Hairy cell leukaemia 2(0.5%), NHL 104(28.1%), Hodgkin’s disease 42(11.4%), Burkitt’s lymphoma 102(27.5%), Multiple myeloma 20 (5.4%) and Plasma cell leukaemia 2(0.5%)The lymphomas were found to constitute the highest prevalence (67.0%), with non-Hodgkin’s lymphoma being the commonest, accounting for about 42% of the lymphoma cases. Hairy cell leukaemia and plasma cell leukaemia were the least seen, each constituting 0.5% of the cases.The distribution of the various haematological malignancies in this study is similar to the pattern reported in previous studies, although, there appears to be generally a lower prevalence of haematological malignancies recorded when compared to the earlier findings.Difficulties in management and poor outcome observed for the various haematological malignancies are attributable to late presentation, high patients default rate, poverty and shortage of chemotherapeutic agents.
Detection thresholds for rare, spectrally unique targets within semiarid rangelands.

Many factors influence classification accuracy, and this study assessed detection thresholds for various sub-pixel targets using QuickBird multispectral imagery. Six iterations of maximum-likelihood classification were used to determine classification accuracy for 100 spectrally unique targets randomly placed over a semiarid rangeland site. Error matrices were calculated using independent validation sites and producer’s, user’s, and overall accuracy, Kappa Index of Agreement, and transformed divergence were analyzed to compare the performance of each classification and determine detection thresholds. Results indicate a strong relationship between target size and classification accuracy (R 2 0.94) as well as an increasingly prominent role played by training site selection as target size decreased. Strong spectral separability and good classification accuracies were achieved for targets 25 percent cover. Sub-pixel targets 25 percent in size were not detectable. This study highlights the effect of target size upon classification accuracy and has direct implications for invasive plant research and rare target detection.
Exchange Rate Pass-Through: What Has Changed Since the Crisis?

We study how exchange rate pass-through to CPI inflation has changed since the global financial crisis. We have three main findings. First, exchange rate pass-through in emerging economies decreased after the financial crisis, while exchange rate pass-through in advanced economies has remained relatively low and stable over time. Second, we show that the declining pass-through in emerging markets is related to declining inflation. Third, we show that it is important to control for non-linearities when estimating exchange rate pass-through. These results hold for both short-run and long-run pass-through and remain robust to extensive changes in the specifications.
Vestibular system dysfunction in patients after mild traumatic brain injury.

INTRODUCTION In the literature there are some discrepancies concerning the occurrence of vertigo and disequilibrium, as well as the type of vestibular dysfunction in patients after mild traumatic brain injury (MTBI). OBJECTIVE The aim of the study was to assess the type of vestibular system dysfunction in MTBI patients after injury at baseline and 6-month follow-up. MATERIAL AND METHODS From a group of 188 patients with vertigo/dizziness and balance instability after MTBI, prospective analysis in 50 patients with abnormal videonystagmography (VNG) were conducted. Anamnesis, otoneurological examination, self-assessed Dizziness Handicap Inventory (DHI) and VNG test were carried in each patient twice - at baseline and after 6 months. RESULTS A significant improvement in the DHI total score (9.8 points, p<0.001) and in the subscales was found after 6 months. At baseline, VNG test showed the peripheral vestibular system dysfunction in 19 cases (38%), central vestibular dysfunction in 20 patients (40%) and mixed vestibular dysfunction in 11 cases (44%). After 6 months, the VNG records normalization was observed in 19 patients (38%), an improvement was significantly more frequently related to peripheral disorders, compared to central ones (p,0.001). CONCLUSIONS In patients after mild traumatic brain injury, about one-fourth of them had vestibular system dysfunction with the same frequency of peripheral, central and mixed lesions in videonystagmography. Subjective post-traumatic symptoms and vestibular system dysfunction in patients after MTBI decrease after 6-month follow-up. However, more than half of patients still have abnormal VNG results, which indicate dysfunction of the central vestibular system.

This study examines the short-term stock price reaction to an acquisition announcement and the long-term post-performance in order to test the existence of a momentum effect in mergers and acquisitions (M&A). The stock price reaction to the announcement of an acquisition is measured by the cumulative abnormal announcement returns (CAARs), while the long-run performance is estimated using the buy-and-hold abnormal returns (BHARs). Using a sample of 3,496 European Union (EU) completed acquisitions between 2002 and 2012, I find evidence of merger momentum by showing that (1) acquirers are more likely to obtain higher CAARs in period of “hot merger markets” (i.e., when previous recent acquirers have also earned higher announcement returns) and (2) the higher abnormal announcement returns tend to revert in the long-run, with acquirers exhibiting lower BHARs. These results are in line with the investor sentiment (optimism) hypothesis in hot merger markets. Further, the findings hold after several robustness tests, including industry fixed effects and the elimination of consecutive acquisitions by the same acquirer that occur in a small time window.
The determinants of stock prices in the Kuwait Stock Exchange: An Extreme Bound Analysis

This paper uses traditional and relaxed extreme bound analysis to test the robustness of the determinants of stock prices for companies listed on the Kuwait Stock Exchange. Based on 1320 regressions, only three out of eleven potentially important variables passed the test. These are previous earnings per share, previous cash flow per share and the price to book value ratio. The final model that included these variables in addition to the earnings per share and the book value per share as the free variables produced a very strong explanatory power. The relaxed extreme bound analysis provided misleading results. JEL Classification: G12-Asset Valuation.
Drip irrigated sunflower intercropping

One of the difficulties in the implementation of agroenergy’s cropping is the growing area competition with subsistence crops. Few studies have been conducted to show the efficiency of intercropping between plants of energy’s potential with cultures of economic sustainability. The objective of this study was to evaluate the effectiveness of intercropping sunflower cultivars with corn and beans, in the initial growth under localized irrigation. The experiment was conducted at the end of the year 2012, in an area of 950 m2, located in the Campus II-UEPB, Lagoa Seca, Paraiba. The irrigation system was managed based on the Reference Evapotranspiration (ETo), calculated by the Penmann-Monteith Method with data obtained locally. The experimental design was a randomized blocks factorial (2 × 4) × 3, with treatments combining two varieties of sunflower in four plantation systems: single or isolated, intercropped with maize, with bean and with caupi. Each plot consisted of four rows of sunflowers in spacing 0.3 × 0.7 m and length of 5 m, interspersed with rows of beans or corn, except in the isolated system. The central rows of sunflowers were used to measure the following growth characteristics: plant height, stem diameter, number of leaves and leaf area. Data were subjected to analysis of variance by F test and the means compared by Tukey test at 5% probability. The diversification of sunflower varieties promoted differences in initial growth, regardless of the cropping system. There was significant effect at 15 DAS, where the sunflower variety “Advanta CF101” had higher plants than the variety “Helio 253” at 40 DAS; the variety “Helio 253” had a stem diameter greater than the “Advanta CF101”.
When was Maximum Transgression on Laurentia during Late Ordovician? New Evidence from Slave Craton and Hudson Bay Basin

The discovery of Richmondian (Late Ordovician) conodonts from Slave Craton on Archean Canadian Shield, in addition to late Edenian (Late Ordovician) conodonts in Hudson Bay Basin, has proved that Late Ordovician transgression on Laurentia was not a one-time event, but went through three phases (Chatfieldian, late Edenian and Richmondian) to reach its maximum in Richmondian time, rather than in Chatfieldian time as previously interpreted.
The Effects of the Bank of Japan's Zero Interest Rate Commitment and Quantitative Monetary Easing on the Yield Curve: A Macro-Finance Approach

This paper empirically investigates the effects of the Bank of Japan's (BOJ) zero interest rate commitment and quantitative monetary easing on the yield curve. Applying a macro-finance approach, we decompose interest rates into expectations and risk premium components and extract the market's perception of the BOJ's policy stance. We make clear the counterfactual policy without the BOJ's commitment. We find some evidence that the commitment lowered interest rates and mat raising the reserve target may have been perceived as a signal indicating the BOJ's accommodative policy stance. The portfolio rebalancing effect has not been found to be significant.
OCCASIONAL PAPERS OF THE MUSEUM OF ZOOLOGY UNIVERSITY OF MICHIGAN

Notropis is the largest, hence from an evolutionary viewpoint most successful, and one of the widest ranging of North American freshwater fish genera. Diversification in size, structural adaptations, habitat, pigmentation, behavior, and other attributes has been sufficiently great that eight or more species of Notropis commonly coexist. Approximately 113 species are currently recognized in the region from the Balsas basin in Mexico to the Mackenzie River in Canada; most inhabit the Atlantic drainage waters of central and eastern United States. In this paper we make known a highly distinctive species, naming it for Carl L. Hubbs, who has played a key role in the development of knowledge of Notropis. He has been personally involved in the description of ten valid species, was the first to discover several others named by colleagues, participated in the description of a number of subspecies, and resurrected several valid species earlier named but long interred in synonymy by less discriminating i~hthyologists. Notropis hubbsi first came to our attention in 1954 when specimens collected by Gerald E. Gunning in Wolf Lake, Illinois, were sent to one of us (RMB) for identification. Soon after, additional specimens from Caddo Lake, Texas, were loaned by Royal D. Suttkus. From the same and an adjacent area Hubbs,
Fracture history of the Divide Creek and Wolf Creek anticlines and its relation to Laramide basin-margin tectonism, southern Piceance Basin, northwestern Colorado

The Divide Creek and Wolf Creek anticlines are two north-northwest-trending, gas-producing intrabasin folds near the eastern margin of the Piceance basin of northwestern Colorado. Natural gas is produced principally from fractured sandstone reservoirs and coals of the Upper Cretaceous Mesaverde Group, the uppermost part of which is exposed sparingly on both folds. The southern part of the Piceance basin was selected for study because it contains obvious intrabasin folds, the Divide Creek and Wolf Creek anticlines, of previously unknown origin adjacent to the tectonically thrusted and folded eastern basin margin. The origin and tectonics of the anticlines are explored in this paper. New seismic and gravity data show that the anticlines are products of late Laramide thrusting. The distribution of several fracture sets discussed in this report are related to this deformation.
Accretion and UV Variability in BP Tauri

BP Tau is one of the few classical T Tauri stars for which the presence of a hot spot in the surface has been reported without ambiguity. The most likely source of heating is gravitational energy released by the accreting material as it shocks with the stellar surface. This energy is expected to be radiated mainly at UV wavelengths. In this work we report the variations of the UV spectrum of BP Tau for 1992 January 5-19, when the star was monitored with IUE during two rotation periods. Our data indicate that lines that can be excited by recombination processes, such as those from O I and He II, have periodic-like light curves, whereas lines that are only collisionally excited do not follow a periodic-like trend. These results agree with the expectations of the magnetically channeled accretion models. The kinetic energy released in the accretion shocks is expected to heat the gas to temperatures of ~106 K, which henceforth produces ionizing radiation. The UV (Balmer) continuum and the O I and He II lines are direct outputs of the recombination process. However, the C IV, Si II, and Mg II lines are collisionally excited not only in the shock region but also in inhomogeneous accretion events and in the active (and flaring) magnetosphere, and therefore their light curves are expected to be blurred by these irregular processes. We also report the detection of warm infalling gas from the presence of redshifted (81 km s-1) absorption components in some of the high-resolution Mg II profiles available in the IUE and Hubble Space Telescope archives.
Reality Exploration and Discovery: Pattern Interaction in Language & Life

The integrating theme of this volume is the influence of K.P. Mohanan's philosophy of inquiry, derived not only from his rich body of work but also from the fresh perspectives and intellectual vitality that he has shared with colleagues and students in a career spanning over three decades.
Feasible earnings momentum in the U.S. stock market: An investor's perspective

This paper examines earnings momentum strategies in the U.S. stock universe from an investor's perspective. Specifically, we use the software Stock Investor Pro from the American Association of Individual Investors (AAII) to obtain the composition of the U.S. stock universe from 2005-2015 on a weekly basis. Raw data is validated via Thomson Reuters Datastream. Next, we implement long-only and long-short earnings momentum strategies based on earnings estimates revisions. Furthermore, we develop a novel price-earnings momentum strategy by intertwining earnings momentum with a 52 week high strategy. Our findings re-confirm the high returns of the classical earnings momentum strategy with equal-weighted raw returns of 23.6 percent p.a. for the monthly long-only strategy. Most importantly, we find large parts of these raw returns to be robust to a wide spectrum of systematic sources of risk and feasible in light of market frictions, such as trading costs, liquidity constraints and microstructure effects. The enhanced price-earnings momentum strategy invests in earnings momentum stocks with below-median distance to their 52 week high. This simple alteration leads to an improvement of annualized raw returns to 31.0 percent, equally robust to systematic sources of risk and market frictions. We conclude that earnings momentum strategies are feasible and continue to pose a serious challenge to the semi-strong form of market efficiency.
Last gasp of V1647 Ori: a brief post-outburst warm, molecular wind

Abstract Followup infrared spectroscopy is reported for V1647 Ori, a young star whose recent eruption illuminated McNeil's Nebula. Lines of HI, H2, and CO are compared to previous observations. We find that the accretion rate fell two orders of magnitude and the CO bandheads disappeared at the end of the outburst. We also report a striking metamorphosis of the fundamental CO spectrum from centrally peaked profiles to emission lines with superimposed blue-shifted absorption lines and back again one year later. This remarkable change in spectral appearance indicates that the system did not return to equilibrium immediately following the outburst. In this paper we propose a mechanism to explain the emergence of a transient post-outburst outflow.
CANDELS: Elevated Black Hole Growth in the Progenitors of Compact Quiescent Galaxies at z ∼ 2

We examine the fraction of massive ( ) compact star-forming galaxies (cSFGs) that host an active galactic nucleus (AGN) at . These cSFGs are likely the direct progenitors of the compact quiescent galaxies observed at this epoch, which are the first population of passive galaxies to appear in large numbers in the early Universe. We identify cSFGs that host an AGN using a combination of Hubble WFC3 imaging and Chandra X-ray observations in four fields: the Chandra Deep Fields, the Extended Groth Strip, and the UKIDSS Ultra Deep Survey field. We find that (65/166) of cSFGs at host an X-ray detected AGN. This fraction is 3.2 times higher than the incidence of AGN in extended star-forming galaxies with similar masses at these redshifts. This difference is significant at the level. Our results are consistent with models in which cSFGs are formed through a dissipative contraction that triggers a compact starburst and concurrent growth of the central black hole. We also discuss our findings in the context of cosmological galaxy evolution simulations that require feedback energy to rapidly quench cSFGs. We show that the AGN fraction peaks precisely where energy injection is needed to reproduce the decline in the number density of cSFGs with redshift. Our results suggest that the first abundant population of massive quenched galaxies emerged directly following a phase of elevated supermassive black hole growth and further hints at a possible connection between AGN and the rapid quenching of star formation in these galaxies.
Monitoring the Evolution of Major Chemical Compound in Dairy Products During Shelf-Life by FTIR

Fourier-transform infrared (FTIR) spectroscopy is considered to be a comprehensive and sensitive method to characterize the chemical composition and for detection of molecular changes in different samples. In this study, FTIRspectroscopyÂ was employed as an rapid and low-cost technique in order to characterize the FTIR spectra and identify appropriate spectral regions for dairy product fermented by a lactic culture consisting by species of Lactococcus lactis and Leuconostoc mesenteroides . A second objective was to monitore the key chemical compounds (lactose, lactic acid, flavors) during fermentation and refrigerated storage (1-21 days, at 4-6Â°C). By FT-IR fingerprint during fermentation we identified changes of the spectra pattern with specific increasing or decreasing peaks for lactose, lactic acid, esters, aromatic compounds, aminoacids, fatty acids. Also the technique was able to identify chemical compounds involved in the microbial activity such as phosphates and phosphorylated carbohydrates during fermentation and dairy product shelf-life. All the major chemical compounds recorded significant increaments during fermentation and refrigerated storage comparing with the raw milk.
