Authors: Llano-Serna Juan F. , Mejía-García Natasha , Calvo-Betancur Víctor D. , Delgado-de Bedout Jorge A. , Lotero-Robledo José G.
Published: December 2019

Introducción: la resonancia magnética en 3 Tesla (3 T) es una herramienta avanzada de diagnóstico por imagen que, debido a la mejoría en la relación señal-ruido, ha logrado disminuir los tiempos de adquisición y ha aumentado la resolución espacial, lo cual lleva a una mejor calidad de la imagen y mayor certeza diagnóstica. Objetivo: describir los hallazgos imaginológicos de la anatomía osteomuscular y algunas lesiones utilizando resonancia magnética de 3 T. Materiales y métodos: se realizó un estudio descriptivo en individuos sanos y con lesiones osteomusculares para evaluar las ventajas del uso de la resonancia magnética en 3 T en el sistema musculoesquelético. Resultados: se seleccionaron, mediante muestreo por conveniencia, ocho individuos con estudios de resonancia magnética de rodilla, hombro, muñeca, cadera, codo, tobillo o patela, algunos de ellos con alteraciones articulares, de ligamentos y de cartílago, y otros con anatomía normal. Los hallazgos de las imágenes por resonancia magnética en 3 T confirmaron la capacidad de esta técnica para detallar las pequeñas estructuras en las articulaciones y en cartílago. Conclusión: el uso de la resonancia magnética en 3 T tiene ventajas por su mayor relación señal-ruido y mayor desvío químico, lo que permite obtener imágenes con mayor resolución para visualizar adecuadamente pequeñas estructuras en grandes o pequeñas articulaciones que no son visualizadas adecuadamente en la resonancia magnética convencional por debajo de 1,5 T.

Nachhaltige Produktivitätssteigerung – ein Vierteljahrhundert Forschung für mehr Effizienz beim Anbau von Zuckerrüben
Authors: Märländer Bernward , Hoffmann Christa , Koch Heinz-Josef , Ladewig Erwin , Niemann Maria , Stockfisch Nicol
Published: December 2019

Im Mittelpunkt des Konzeptes einer nachhaltigen Produktivitätssteigerung steht die Steigerung der Effizienz (Output/Input-Relation) entlang der gesamten Wertschöpfungskette. Die Forschungstätigkeit im Institut für Zuckerrübenforschung (IfZ) an der Universität Göttingen wurde im vergangenen Jahrzehnt zunehmend auf die Effizienzsteigerung im Anbau ausgerichtet. Die sich daraus ergebende Entwicklung wird für den Anbau von Zuckerrüben in Deutschland beschrieben. Der tatsächlich erzeugte Zucker (Weißzuckerwert, „Zucker im Silo“) stieg in Deutschland von etwa 7tha–1 1970 auf aktuell etwa 12tha–1. Dagegen betrug der Bereinigte Zuckerertrag in der Wertprüfung des Bundessortenamtes 2015 etwa 15tha–1. Der Ertragsanstieg beruht auf biologisch-technischem Fortschritt, je zur Hälfte realisiert durch Züchtung und verbessertes Anbaumanagement bzw. günstige Witterung. Mit dem Ertrag stiegen auch der Chlorophyll- gehalt im Blatt und das Rübe-Blatt-Verhältnis, während sich in der Speicherwurzel der Anteil an Strukturkohlenhydraten (Mark) zu Gunsten der Speicherkohlenhydrate (Saccharose) verringerte. Ein zu niedriger Markgehalt kann die Lagerfähigkeit beeinträchtigen. Die N-Düngeeffizienz hat sich erheblich verbessert und beträgt kontinuierlich fallend zurzeit etwa 10kgNt–1 Zucker. Der Anbau von Zuckerrüben ist – ganz im Sinn des integrierten Pflanzenschutzes – gekennzeichnet durch den Anbau von toleranten/resistenten Sorten gegen Cercospora beticola, Rizomania, Heterodera schachtii und Rhizoctonia solani, eine Applikation von maximal etwa 100gha–1 an Insektiziden (Neonicotinoide in der Pillenhüllmasse) und die Applikation mehrerer verschiedener herbizider Wirkstoffe, durch die das Resistenzrisiko gering ist. Weiterhin wurden Leitlinien des integrierten Pflanzenschutzes entwickelt, die über Branchenvereinbarungen zwischen Zuckerunternehmen und Anbauern für den gesamten Zuckerrübenanbau gültig sind. Zentrale Bedeutung hat der Anbau ausschließlich in Fruchtfolgen. Durch eine weitere Erhöhung auf etwa 15tha–1 Weißzuckerwert und 18tha–1 Bereinigter Zuckerertrag wird die Energieeffizienz bis 2030 auf etwa 20 GJ Output/GJ Input steigen. Voraussetzung für eine weitere nachhaltige Produktivitätssteigerung des Anbaus sind wissenschaftlich unabhängige Forschung, ein intensiver Wissenstransfer in die Praxis und gesellschaftliche Akzeptanz für technologisch innovative sowie effizientere Anbauverfahren. Zukünftig werden Themen wie z.B. Schaderregerdiagnose auf molekularer Basis, Sensorik, Robotik und Data Mining, letztlich Smart Farming, bearbeitet und es gilt den physiologischen Idiotypus von Beta vulgaris und damit das Ertragspotenzial für Zuckerrüben in Mitteleuropa zu bestimmen.
Analysis of Carbon Monoxide Gas Dilution on Horizontal Tunnel Front using Laboratory Scale Physical Model
Authors: Harnoko Addien Wisnu , Widodo Nuhindro Priagung , Ihsan Ahmad
Published: December 2019

Potential hazards that often occur in underground tunnels are dangerous and toxic gases, one of which is carbon monoxide (CO) which can be found in underground tunnels for example as a result of imperfect detonation on work surfaces. CO gas is very poisonous so it can cause death. This study aims to determine the spread of CO gas when diluting with tunnel ventilation in the horizontal front. This research was conducted on a physical model of the laboratory with a ratio of 1:10 compared to the actual tunnel, that is at the cross section of the model in the laboratory 40 cm x 40 cm. The effectiveness of dilution or dilution is indicated by the value of the diffusion coefficient, where the greater the diffusion coefficient, the more diffused the CO gas concentration, so the faster the CO gas concentration decreases. The parameters of the test conditions are the ratio of the duct to face distance (L/D) and the Reynolds number (Re) which shows the variation of air velocity in the tunnel work surface. Test results from the distribution of CO gas showed the influence of the configuration of the forcing duct and exhausting duct distances on the working front to the CO gas dilution. In this study also found the influence of Reynolds numbers on the value of the diffusion coefficient, that the greater the value of Re, the greater the value of E.

The Andriake Marbles: record of “a small ruined temple of very white marble” -a Roman 1st – 2nd century hilltop mausoleum and coastal navigational marker at Andriake, Lycia, that disappeared in the early 19th c.
Authors: Duggan Terrance Michael Patrick
Published: December 2019

There
is first hand record, pictorial, cartographic and in published texts of the
presence of a small Roman square in plan temple-tomb in the Corinthian Order
constructed of very white marble on a prominent coastal hilltop behind
Hadrian’s horrea at Andriake, the port of Myra. It was a structure that from
its location would also have served as a coastal navigational marker over the
course of about 1600 years. All of the surviving primary evidence for it dates
from the two decades between 1792 and 1812. Although reference continued to be
made to this structure from these first hand sources into the latter part of
the 19th c., this building no longer stood in this location. There
is no primary evidence for the presence of this Roman structure on this hilltop
at Andriake after 1812. Due to the absence of visible physical remains in this location today, in the
recent literature, the record made of it, has been regarded as a inaccurate record
of a nearby Hellenistic tower, a caprice introduced by the artist Luigi Mayer
into his view of Hadrian’s horrea at the Port of Myra-Andriake of 1792, which,
was then repeated by the British Admiralty hydrographer Captain Beaufort in his
work, which seems inexplicable, or has been ignored.This
article shows this building stood in this hilltop location at Andriake the port
of Myra until 1812 and provides record to indicate that this structure was
deliberately and methodically removed without Ottoman permission from its
hilltop location in September-early October 1812, at the time that the Society
of the Dilettanti Mission to Ionia led by William Gell was at Myra-Andriake. It
also suggests a measured architectural record of this structure was certainly
made, but note of these dra­wings was not published by the Society of
Dilettanti in 1814.

Suggestions are made
as to the possible location of this building today and it seems most probably
the case, in the absence of record of this reassembled Roman structure in
Britain or elsewhere over the course of the past 200 years, that the vessel
transporting the disassembled parts of this Roman building sank, was sunk, or to save the ship,
this heavy cargo was cast into deep water, most probably in late 1812 or in
1813. The name of the vessel used by William Gell for transport, or perhaps,
two vessels, if the Andriake Marbles were offloaded within the Mediterranean
for transshipment, as was often the case, is unknown today, as the handwritten
Journal of the Dilettanti Mission to Ionia of 1811 to 1813, the property of the
Society of Dilettanti, which would have recorded this, and much else besides
concerning this monument, has been lost.

Timbriada et son Territoire
Authors: Labarre Guy
Published: December 2019

Several aspects concerning Timbriada and its territory,
discussed in two recent publications (Cl. Brixhe 2016 – H. Bru 2017), are
treated in this article: the questions of the location of the city, the
territorial conflict with the city of Apollonia and the extension of the
territory of the city. The idea that the site of Timbriada was near Akçaşar is
maintained. The analysis of territories disputed with Apollonia must be
conducted with caution and method, and indicates a location rather southeast of
Lake Eğridir. For the extension of the territory of the city, it is highlighted
by recent epigraphic and archaeological discoveries.
Developed Automated Vehicle Traffic Light Controller System for Cities in Nigeria
Authors: Ojieabu Clement E
Published: December 2019

This paper presents a research work that was carried out to resolve challenges of traffic light system. This work employs the use of a microcontroller, an inductive loop which acts as the vehicle detector and LED’s (light emitting diodes) for simulating the red, yellow and green light in a traffic light. The inductive loop is embedded in pavement along the road which senses the presence of vehicle. When a vehicle passes across the loop, the magnetic field changes and the inductance of the coil is decreased resulting in a frequency change of the oscillator which is detected by the controller. The interrupt is set to make the traffic light allow the movement of vehicles on the lane with many vehicles on it according to information on the counter. This means that when the system discovers the lane with many vehicles by the number on the counter, the interrupt function comes into operation by interrupting the counting process and allowing the system to allow movement in that lane. Then the system resumes back to counting after this process is done. The test results show that the system can be physically and successfully implemented.
Design and Fabrication of a Plastic Film Granulating Machine
Authors: Imaekhai Lawrence
Published: December 2019

Plastic film granulating machine is an industrial machine used for reducing plastic materials, mostly for grinding plastic into granules of uniform sizes for further processing either into new plastic shapes or recycled back to its parental source. This paper presents the use of locally sourced materials for realising the same machine; reducing its size and cost, while maintaining high efficiency, as well as decrease in vibration and increased shear efficiency with uniform size of granules. The machine consists of the hopper, the grinding chamber in which contains the shaft and cutting blades with a discharge unit. The plastic film granulator has a capacity of granulating 1kg of recycled plastic in 1h at 75% efficiency, a working revolution of 3000rpm, and power rating of 5.5hp engine.  The machine works by principle of shearing, power is transferred from the motor to the granulating shaft with the aid of a transmission coupler that connects them. The inlet plastics are granulated until the desired size is achieved, small enough to pass through the discharge screen.
Covariance-regularized Reconstruction of Data Cubes in Integral Field Spectroscopy and Application to MaNGA Data
Authors: Liu Dou , Blanton Michael R. , Law David R.
Published: December 2019

Integral field spectroscopy can map astronomical objects spatially and spectroscopically. Due to instrumental and atmospheric effects, it is common for integral field instruments to yield a sampling of the sky image that is both irregular and wavelength dependent. Most subsequent analysis procedures require a regular, wavelength-independent sampling (for example a fixed rectangular grid), and thus an initial step of fundamental importance is to resample the data onto a new grid. The best possible resampling would produce a well-sampled image, with a resolution equal to that imposed by the intrinsic spatial resolution of the instrument, telescope, and atmosphere, and with no statistical correlations between neighboring pixels. A standard method in the field to produce a regular set of samples from an irregular set of samples is Shepard’s method, but Shepard’s method typically yields images with a degraded resolution and large statistical correlations between pixels. Here we introduce a new method, which improves on Shepard’s method in both these respects. We apply this method to data from the Mapping Nearby Galaxies at Apache Point Observatory survey, part of Sloan Digital Sky Survey IV, demonstrating a full width at half maximum close to that of the intrinsic spatial resolution (and ∼16% better than Shepard’s method) and low statistical correlations between pixels. These results nearly achieve the ideal resampling. This method can have broader applications to other integral field data sets and to other astronomical data sets (such as dithered images) with irregular sampling.
On the Observations of Rapid Forced Reconnection in the Solar Corona
Authors: Srivastava A. K. , Mishra S. K. , Jelínek P. , Samanta Tanmoy , Tian Hui , Pant Vaibhav , Kayshap P. , Banerjee Dipankar , Doyle J. G. , Dwivedi B. N.
Published: December 2019

Using multiwavelength imaging observations from the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory on 2012 May 3, we present a novel physical scenario for the formation of a temporary X-point in the solar corona, where plasma dynamics are forced externally by a moving prominence. Natural diffusion was not predominant; however, a prominence driven inflow occurred first, forming a thin current sheet, thereafter enabling a forced magnetic reconnection at a considerably high rate. Observations in relation to the numerical model reveal that forced reconnection may rapidly and efficiently occur at higher rates in the solar corona. This physical process may also heat the corona locally even without establishing a significant and self-consistent diffusion region. Using a parametric numerical study, we demonstrate that the implementation of the external driver increases the rate of the reconnection even when the resistivity required for creating normal diffusion region decreases at the X-point. We conjecture that the appropriate external forcing can bring the oppositely directed field lines into the temporarily created diffusion region first via the plasma inflows as seen in the observations. The reconnection and related plasma outflows may occur thereafter at considerably larger rates.
Jellyfish: Resolving the Kinematics of Extreme Ram-pressure Stripping at z ∼ 0.3*

†
Authors: Kalita Boris S. , Ebeling Harald
Published: December 2019

We present and discuss results from the first spatially resolved kinematic study of ram-pressure stripping of a massive late-type galaxy at intermediate redshifts. Our target, the spectacular “jellyfish” galaxy, A1758N_JFG1, was previously identified as a fast-moving member of the equal-mass merger A1758N (z = 0.28), with a star formation rate of 48 M
☉ yr−1, far above the galaxy main sequence. Integral field unit (IFU) data obtained by us unambiguously confirm ram-pressure stripping as the physical mechanism driving the optical morphology and high star formation rate of this system by revealing extended [O ii]λ3727 Å emission up to 40 kpc (in projection) downstream, as well as an ordered radial-velocity field generated by (a) conservation of angular momentum of the interstellar gas stripped from the edge of the galactic disk and (b) drag forces exerted by the intracluster medium on the “tentacles” of stripped material. We find no evidence of significant nuclear activity in A1758N_JFG1, although an AGN might, at this early stage of the stripping process, be obscured by high column densities of gas and dust near the galactic core. Finally, our exploration of possible trajectories of A1758N_JFG1 found solutions consistent with the notions (a) that the A1758N merger proceeds along an axis that is substantially inclined with respect to the plane of the sky and (b) that A1758N_JFG1 participated in the merger, rather than having been accreted independently from the field.
Large-scale Multiconfiguration Dirac–Hartree–Fock Calculations for Astrophysics: Cl-like Ions from Cr viii to Zn xiv
Authors: Wang K. , Jönsson P. , Del Zanna G. , Godefroid M. , Chen Z. B. , Chen C. Y. , Yan J.
Published: December 2019

We use the multiconfiguration Dirac–Hartree–Fock (MCDHF) method combined with the relativistic configuration interaction approach (GRASP2K) to provide a consistent set of transition energies and radiative transition data for the lower n = 3 states in all Cl-like ions of astrophysical importance, from Cr viii to Zn xiv. We also provide excitation energies calculated for Fe x using the many-body perturbation theory (MBPT, implemented within FAC). The comparison of the present MCDHF results with MBPT and with the available experimental energies indicates that the theoretical excitation energies are highly accurate, with uncertainties of only a few hundred cm−1. Detailed comparisons for Fe x and Ni xii highlight discrepancies in the experimental energies found in the literature. Several new identifications are proposed.

'We do not have to be vicious, competitive, or managerial'
Authors: Emejulu Akwugo , Littler Jo
Published: December 2019

Akwugo Emejulu discusses changes to 'collective public politics' – including the third sector, activism, community development and political and union campaigning – alongside Black feminist activism, her own intellectual development, and institutional racism at British universities.
In these right-wing times, she argues 'we need people in lot of different kinds of spaces and places to take back power'. She outlines the consequences of the defeat of the left since the 1980s and the rise of neoliberal technocratic managerialism in the third sector: how it put already-vulnerable
people further at risk and destabilised the political power of NGOS. More recently there has been a surge of interest in political education and in campaigning on 'the bigger political picture' amongst community activists. We need a far more expansive conception of 'activism': for more attention

in a neoliberal climate. 'We do not have to be vicious, competitive, or managerial', she says: all academics need to behave well at every level to change institutional racism.

The majority of acromioclavicular ioint injuries resuit from direct trauma to the shoulder. The magnitude of applied force determines the degree of injury. This article presents a modified Weaver-Dunn procedure consisting of lateral clavicle resection and reduction, coracoclavicular fixation with suture or surgical tape, and coracoacromial ligament transfer for the treatment of these injuries.
Evaluation of a New Power-Operated PMMA Vacuum Mixing and Delivery System for Cemented Femoral Stem Insertion
Authors: Lahav Amit , DiMalo Frank R
Published: December 2019

Abstract

Variations exist in the manual preparation and delivery of cement during primary total hip arthroplasty. The incorporation of a power source may standardize cement mantle manufacturing. This study prospectively compared the use of a new power-operated polymethylmethacrylate vacuum mixing and delivery system to a commonly used manually powered industry standard. The study did not reveal a significant difference in the quality of cement mantle grades when comparing the use of this power-operated system to an industry standard manual system. However, the benefit of the new preparation and delivery system may be in consistent porosity reduction and not in the improvement of cement mantle grading.
The Ponseti Method of Treatment for Congenital Clubfoot: Importance of Maximal Forefoot Supination in Initial Casting
Authors: Frick Steven L
Published: December 2019

abstract

The correction of cavus deformity requires further supination of the forefoot. In the Ponseti method, the initial cast is applied with the forefoot supinated such that the plane of the metatarsal heads is parallel to the long axis of the tibia. This study reviewed Pirani scores of 27 patients with 38 clubfeet treated over an 18-month period by the Ponseti method to evaluate changes in midfoot deformity after the initial cast. Initial average scores for severity of the lateral border deformity, medial crease, and talonavicular joint reducibility decreased from 0.92, 0.75, and 0.75, respectively, to 0.73, 0.25, and 0.5, respectively, after the first cast. The improvement in Pirani scores provides support for the efficacy of the initial cast to reduce the cavus and also increase the reducibility of the midfoot. Failure to address the cavus deformity with the initial cast as described by Ponseti may lead to persistent rigidity and incomplete correction.
Adverse Childhood Experiences: Missed Opportunities by Nurse Practitioners to Screen Adult Clients
Authors: Branstetter M. Laurie , Garrett-Wright Dawn , Padgett Brooke
Published: December 2019

Adverse childhood experiences (ACE) occur as a result of abuse/neglect during childhood and household dysfunction. More than one half of adults have experienced at least one ACE, and this can lead to impaired coping and risky health behaviors. The purpose of the current study was to determine the relationship between nurse practitioner (NP) knowledge of ACE and screening practice for childhood trauma in a mid-southern state. Forty-four NPs participated in the survey. Of NP participants, 15% reported routinely screening for a history of childhood abuse. Psychiatric–mental health NPs were more knowledgeable about ACE screening and more confident in screening practices. All providers reported lack of time as the most frequent barrier to screening for ACE. NPs who regularly screen patients are more knowledgeable about the nine knowledge questions regarding ACE. Insufficient time to evaluate or counsel clients was a universal barrier across the sample. [

Authors: Fraenkel Graham , Comaish Ian F , Lawless Michael A , Kelly Megan R , Dunn Stewart M , Byth Karen , Webber Suzanne K , Sutton Gerard L , Rogers Christopher M
Published: December 2019

ABSTRACT

PURPOSE: To assess vision in patients with myopia and myopic astigmatism before and after refractive surgery.

METHODS: A prospective controlled study of visual quality amongst myopes and astigmatic myopes. Focus groups, ophthalmic surgeons, and questionnaire experts devised a Subjective Vision Questionnaire (SVQ), modified after a pilot trial. Participants were administered the SVQ before clinical evaluation. Items answered by over 95%, with factor loadings >0.55 were included. Test-retest reliability was assessed by repeat testing. Factor analysis identified groups of questions measuring particular dimensions of data.

RESULTS: Sixty-seven items were answered by 128 patients and reduced to 24 items in a final questionnaire. Factor analysis identified six types of questions within the questionnaire, the most important of which was related to driving.

CONCLUSION: The simplicity, low cost, and psychometric properties of the Subjective Vision Questionnaire support its use clinically and in research. [J Refract Surg 2004;20:10-19]

Authors: Barequet Irina S , Wygnanski-Jaffe Tamara , Hirsh Ami
Published: December 2019

ABSTRACT

PURPOSE: To report the results of laser in situ keratomileusis (LASIK) in a series of adult patients with amblyopia.

METHODS: A retrospective noncomparative review was performed on patients with amblyopia who underwent LASIK for correction of ametropia, using the Summit Krumeich Barraquer microkeratome and the Nidek EC-5000 excimer laser. Data were collected on uncorrected visual acuity, best spectacle-corrected visual acuity, manifest refraction, anterior segment evaluation, intraocular pressure, corneal topography, and dilated fundus examination (preoperative and postoperatively on day 1, months 2 and 6).

RESULTS: Eight eyes of seven patients were included, with a mean patient age of 30 ± 10 years (range 21 to 49 yr). Mean preoperative spherical equivalent refraction was -4.70 D (range -12.62 to +4.71 D) and the best spectacle-corrected visual acuity varied from 20/32 to 20/80. At 2 months after LASIK, mean spherical equivalent refraction was -0.37 ± 0.60 D (range -1.37 to + 0.60 D), uncorrected visual acuity ranged between 20/20 to 20/30, and a mean gain of 3 Snellen lines (range 2 to 4 lines) was observed. All patients reported significant subjective improvement in their perception of vision. The visual acuity and subjective improvement were maintained throughout 6 months postoperatively.

CONCLUSIONS: LASIK with the Nidek EC-5000 laser for correction of ametropia in adult amblyopic eyes provided encouraging results for visual acuity improvement beyond correction of the refractive error. [J Refract Surg 2004;20:25-28]

Published: December 2019

ABSTRACT

PURPOSE: To assess the effectiveness of optical and ultrasonic pachymetry when examining corneas of patients before and after laser in situ keratomileusis (LASIK).

METHODS: We conducted a prospective study of 25 patients (50 eyes) who had LASIK for myopia or myopic astigmatism (mean spherical equivalent refraction -4.80 ± 3.60 D; range -1.75 to -12.00 D). Corneal thickness was measured using 1) conventional ultrasonic pachymetry (20 MHz probe) in the central cornea, 2) ASL confocal microscopy (CMTF analysis), 3) Orbscan II Analyzer, and 4) ultrasound biomicroscopy (UBM) (50 MHz probe) preoperatively and 3 months postoperatively.

RESULTS: Preoperative pachymetry values measured with the Orbscan II Analyzer (551.3 ± 27.3 µm) were almost identical to those measured with the 20 MHz ultrasonic probe (553.7 ± 25.7 µm; t-test P=.652). The mean preoperative pachymetry for UBM was 566.7 ± 38.8 µm and for CMTF was 553.2 ± 15.5 µm. The optic and ultrasonic system measurements differed in operated eyes; 20 MHz ultrasonic pachymetry yielded an average 478.7 ± 23.5 µm and the UBM, 482.4 ± 40.3 µm. These measurements differed from the Orbscan II (Tukey test; P=.023) measurement of 461.1 ± 37.5 µm but not from the confocal microscopy measurement of 475.2 ± 41.8 µm. UBM registered greater values that were more variable than those obtained with ultrasonic pachymetry.

CONCLUSIONS: In non-operated eyes, corneal thickness was similar using conventional ultrasound, Orbscan II, or confocal techniques, with ultrasound biomicroscopy giving thicker readings. [J Refract Surg 2004;20:29-34]
Potentially Accommodating Intraocular Lenses - An In Vitro and In Vivo Study Using Three-dimensional High-frequency Ultrasound
Authors: Stachs Oliver , Schneider Hanka , Stave Joachim , Guthoff Rudolf
Published: December 2019

ABSTRACT

PURPOSE: To investigate the accommodative performance of new intraocular lenses (IOLs) using the advantages of three-dimensional ultrasound biomicroscopy.

METHODS: An in vitro simulation device was designed to study IOL performance using an artificial capsular bag and a stretching device. The haptic region of the Akkommodative 1CU (HumanOptics AG) and CrystaLens AT-45 (Eyeonics Inc) was visualized in vitro in three dimensions, using an in-house developed three-dimensional ultrasound biomicroscope. The in vitro results were used to describe the in vivo situation in four patients with accommodative implants.

RESULTS: The haptic position and angulation in consideration of the accommodation state was distinguished and analyzed. In the simulation model, a maximal angulation change of 4.5° and 4.3° and a maximal forward shift of 0.33 mm and 0.28 mm was observed for the AT-45 and 1CU, respectively. In vivo, a change in haptic angulation <10° and a maximal forward shift of 0.50 mm was observed For the 1CU. These changes correspond to a theoretical approximate value of 0.50 diopters.

CONCLUSIONS: The in vitro simulation device examined with three-dimensional ultrasound biomicroscopy provided information on the accommodative performance of these potentially accommodative IOL designs. Using three-dimensional ultrasound biomicroscopy, corresponding changes in haptic angulation during pharmacological-induced accommodation were observed. [J Refract Surg. 2005;21:37-45.]
Triptans and the Incidence of Epithelial Defects During Laser in situ Keratomileusis
Authors: Hardten David R , Hira Neelu K , Lombardo Anthony J
Published: December 2019

ABSTRACT

PURPOSE: To investigate whether the incidence of epithelial defects during laser in situ keratomileusis (LASIK) was different in patients who were taking sumatriptan (Imitrex, Glaxo Smith Kline, Pittsburgh, Pa) for migraine headaches than in those who were not.

METHODS: A retrospective chart review was performed on 54 eyes of 28 patients who had been identified as taking sumatriptan and had undergone LASIK at Minnesota Eye Consultants between 1999 and 2001. These patients were compared with 54 gender- and age-matched control eyes operated on with the same microkeratome at the same location during the same period of time. The incidence of epithelial defects during LASIK was compared between the two groups.

RESULTS: In the sumatriptan group, 11.1% (6 of 54) of eyes developed epithelial defects as compared to 9.3% (5 of 54) of eyes in the non-triptan group (P=.75, chi square). More recent sumatriptan exposure did not increase the incidence of epithelial defect (P=.47). In patients in whom sumatriptan was stopped >1 month prior to LASIK, 6.3% (1 of 16 eyes) had epithelial defects; in patients in whom sumatriptan was stopped <1 month prior to LASIK, 14.3% (4 of 28 eyes) developed epithelial defects; and 9.3% (5 of 54 eyes) of patients in whom no triptans had ever been used had epithelial defects (P=.70).

CONCLUSIONS: There is no correlation between the use of sumatriptan for relief of migraine headaches and the generation of epithelial defects during LASIK. There appears to be no reason to stop triptans before proceeding with LASIK. [J Refract Surg. 2005;21:72-76.]
CD13/Aminopeptidase N Is a Potential Therapeutic Target for Inflammatory Disorders
Authors: Lu Chenyang , Amin Mohammad A. , Fox David A.
Published: December 2019

CD13/aminopeptidase N is a widely expressed ectoenzyme with multiple functions. As an enzyme, CD13 regulates activities of numerous cytokines by cleaving their N-terminals and is involved in Ag processing by trimming the peptides bound to MHC class II. Independent of its enzymatic activity, cell membrane CD13 functions by cross-linking–induced signal transduction, regulation of receptor recycling, enhancement of FcγR-mediated phagocytosis, and acting as a receptor for cytokines. Moreover, soluble CD13 has multiple proinflammatory roles mediated by binding to G-protein–coupled receptors. CD13 not only modulates development and activities of immune-related cells, but also regulates functions of inflammatory mediators. Therefore, CD13 is important in the pathogenesis of various inflammatory disorders. Inhibitors of CD13 have shown impressive anti-inflammatory effects, but none of them has yet been used for clinical therapy of human inflammatory diseases. We reevaluate CD13’s regulatory role in inflammation and suggest that CD13 could be a potential therapeutic target for inflammatory disorders.
