Aspects of Seismotectonics of Eastern China and their Implications for Eastern U. S.
Authors: Wu Francis T.
Published: July 2019

Earthquakes in eastern China and the eastern United States occur far away from known plate boundaries. M ≥ 8 and 6 < M < 8 events occurred in both areas throughout known history, but the frequency of occurrence of earthquakes was apparently higher in eastern China than in the eastern U.S. Eastern China is composed of many geologically different blocks, which are often bounded by active faults. In comparison the eastern U.S. geology is less heterogeneous. Whereas seismicity in eastern China is frequently, although not always, dearly related to neotectonic activities along the boundaries of “rigid block”, most of the seismogenic structures associated with eastern U.S. events are often overlain by thick recent sediments or have not yet been clearly deciphered; two “rigid blocks” in the eastern U.S. with recognizable seismogenic structures on all sides are tentatively identified. Judging from the episodicity of earthquake occurrence in eastern China in the last 2000 years, we do not yet have enough time to assess the true recurrence rate of earthquakes in the eastern U.S (with a historical record spanning only 400 years). If some eastern U.S. earthquakes occur along boundaries of blocks as they do in eastern China, areas next to the historically active areas in the eastern U.S. may also be sites of significant future seismicity.
The Utility of Geopotential Field Data in Seismotectonic Studies in the Eastern United States
Authors: Hinze William J. , Hildenbrand Thomas G.
Published: July 2019

The deterministic approach to seismic hazard evaluation utilizes all available geologic/geophysical information to map the structure and nature of the crust in three dimensions that may relate to earthquake activity. However, information on the crystalline crust of the eastern United States from direct observations, drilling and sparse crustal seismic studies is limited. In contrast, regional gravity and magnetic anomaly data exist over the entire eastern United States and are available in a digital grid to facilitate processing and analysis. Although these data have serious limitations for detailed interpretation, they can be used to estimate the strength of the crust and the lithosphere and to map and characterize (1) zones of weakness such as paleorifts, sutures, and faults; (2) regions of potential stress amplifications such as plutons and irregularities in fault zones; and (3) basement terranes of generally consistent structural pattern that may delimit coherent regional seismic zones.

Free-air, Bouguer, and isostatic gravity anomalies have different applications in the characterization of the crust for seismogenic purposes and complement magnetic anomaly maps which focus on upper crustal features. In concert, these data have provided the insight to interpret the host structures that together with related seismic and geoscience data, suggest causative mechanisms of the New Madrid seismic zone and other seismogenic regions of the eastern United States. As a result, we conclude that interpretations of geopotential anomalies are an essential ingredient in seismotectonic studies in the eastern United States, but they are only one of several tools required in the concerted effort of assessing seismic hazards. The presence of anomalies with a particular set of attributes neither confirms nor denies the possible spatial relationship to seismicity.
Are Active Mid-Plate Fault Zones of the Central United States Interconnected?
Authors: Slemmons D. B. , Ramelli A. R.
Published: July 2019

It is generally assumed that faults in mid-plate regions, such as central and eastern United States (CEUS), unless historically active, are inactive and/or lack a potential for large earthquakes. The Meers fault in Oklahoma, located in an historically aseismic area, is a spectacular exception to this rule. Paleoseismic studies of this fault show that the most recent large event occurred about 1200 years ago, had a magnitude of more that MS = 7 or 7.5, a surface rupture of 40 km length, and several meters of net displacement on a major left-lateral fault (Ramelli and Slemmons, in press).

At least four fault zones in other parts of CEUS indicate that the Meers faulting event is not unique, including: (1) New Madrid epicentral region with three events of about MS = 8 in 1811 and 1812 with surface faulting and deformation (Russ, 1982), (2) Washita Valley fault (Cox and VanArsdale, 1986), (3) Kentucky River fault (VanArsdale, 1986), and possibly (4) faulting near Pierre, South Dakota (Nichols and Collins, 1987). Moreover, such midplate active faults are not unique, for there are at last four similar examples of historical seismogenic faulting (McCue and others, 1987) with earthquakes of up to 6.9 magnitude.

Most active fault zones can be dearly demonstrated to be parts of branching or interconnected tectonic systems, implying transfer of stress and strain along zones of deformation. We speculate that tectonically active mid-plate fault zones may also be parts of much longer, interconnected active systems, rather than isolated “hot spots” of activity resulting solely from the response of local crustal flaws to a regional stress field.
Structural Control of Seismicity in the Northeastern U. S.
Authors: Seeber L.
Published: July 2019

Seismicity in the northeastern U. S. can often be correlated to preexisting structural features. This correlation is found over a wide range of scales and distinct types of correlation characterize the opposite ends of this range. Firstly, patterns of seismicity measured in tens or hundreds of kms are recognized in maps of recent epicenters from regional networks and in maps of earlier macroseismic epicenters. These patterns are characterized by epicenter bands of resolvable widths, but, within these bands, individual ruptures are often oriented at large angles to the strike of the bands. Several of these seismicity patterns can be spatially correlated to structural features in the crystalline layer of the upper crust which is the source of seismicity. These features are recognized as major lithologic boundaries or suture zones, characterized by ductile deformation without evidence for a subsequent brittle phase. Hence, these large scale features are not preexisting weaknesses reactivated in the current regime. Stress concentration derived from lithologic and rheologic contrast along the boundaries may be an important mechanism in these cases. Secondly, high resolution of aftershock zones in areas where the seismogenic layer outcrops has allowed detailed correlation between ruptures and brittle features. Two cases, one in the Grenville terrane of the craton and the other in the Manhattan Prong along the crystalline core of the Appalachians, show similar characteristics. The ruptures are small, 1.5 and 0.5 kms respectively, but their geometry is well defined by the aftershocks. Both these ruptures are associated with zones of brittle fractures that can be followed at the surface for more than 10 kms. These fracture zones are primarily recognized as topographic lineaments, concentrations of slikensided joints and sets of small en echelon faults. The aftershocks zones are parallel to the individual faults in these en echelon fault sets. The total accumulated horizontal displacement across these fracture zones is small (less than 50 to 100 meters) when compared to the rates of moment release and to the inferred pre-Cenozoic age of these fracture zones. The maximum magnitude from these fracture zones is probably controlled by the size of individual faults in the en echelon pattern, rather than by the much larger dimension of the entire fracture zone.
Establishment of GPS Strain Monitoring Networks in the Eastern United States
Authors: Strange W. E.
Published: July 2019

The National Geodetic Survey (NGS) in cooperation with a number of federal agencies, state and local groups and universities is establishing GPS networks in the United States, east of the Rocky Mountains, which can be used to monitor strain and vertical deformation. These GPS networks are tied to a framework of some 14 fixed and mobile VLBI sites. In cooperation with the Nuclear Regulatory Commission (NRC), NGS established a 45 station GPS regional network in Nov.–Dec. 1987 which is tied to the VLBI framework. This network is scheduled for reobservation in 1989 and funds permitting, at regular intervals thereafter. A number of additional, more dense networks have been or are in the process of being established. The Tennessee Department of Transportation has established a 60 station statewide network to act as a reference network for surveying in conjunction with road construction. This network is expected to have an accuracy of a few parts in 107. NGS in cooperation with the NRC and the University of Maine established in 1986 a high accuracy GPS network in southeast Maine. In 1987 NGS in support of the Federal Aviation Administration (FAA) has established approximately 100 stations throughout Ohio with an accuracy in the 1:106 to 1:107 range. Toward the end of 1988, NGS, working in conjunction with several state agencies and the University of Florida, will establish a statewide network of about 140 stations with an accuracy in the 1:106 to 1:107 range. NGS, in cooperation with the Department of Energy, has also established a high accuracy to 1:107 to 1:108 GPS traverse from Florida to Maine connecting stations at tide gauge sites. The State of Texas is establishing a number of permanent GPS stations in support of highway surveying. These stations will allow strain monitoring across Texas at the 1:108 level. Additional networks are in the planning stage.

It is clear that large numbers of high accuracy GPS networks are being established throughout the eastern United States. Many of these networks are being established for other than geophysical purposes. In many cases the state highway departments and others are interested only in 1:106 accuracy. As a practical matter this means that to assure 1:106 accuracy a few parts in 107 accuracy (1 to 3 cm over 100 kms) is often attained, but this is by no means certain. Also there are normally no plans for systematic resurveys, only replacement of destroyed monuments. A challenge to the geophysical community is to interact with the groups undertaking the high accuracy surveys to assure that, at points of geophysical interest, satisfactory accuracies are achieved during initial epoch measurements. This means that a satisfactory number of observations are obtained and high accuracy reduction methods are used in obtaining differential positions from the data. The geophysical community must also develop plans for resurvey of geophysically interesting network components on a systematic basis.
Seismic History of Minnesota and It’s Geological Significance: An Update
Authors: Chandler Val W. , Morey G. B.
Published: July 2019

High-resolution aeromagnetic data have recently been acquired for most of Minnesota under the sponsorship of the Minnesota Future Resources Commission, which also provided funds for test drilling of selected anomalies. The new data show that northwest-trending dikes and fractures are much more common in the Archean terranes than previously believed, and several epicenters are near such faults. The northeast-trending Great Lakes tectonic zone (GLTZ) was thought to be the chief source of seismicity in the state, because several epicenters were aligned with it. However, more recent seismic reflection profiling has demonstrated that the GLTZ has a moderate dip to the north. This dip is not compatible with the previously favored focal plane solution for a relatively large earthquake, which apparently confirmed the seismogenic role of the GLTZ. The alternative focal plane solution for this earthquake, however, is compatible with some northwest-trending structures in the region.

We propose that the apparent alignment of epicenters with the GLTZ is related to stress buildup at places where it is intersected by northwest-trending faults, with subsequent movement occurring upon release. A similar model may explain seismicity along the northeast-trending Colorado lineament to the southwest.
Estimation Theory for Peak Ground Motion
Authors: Ou Gwo-Bin , Herrmann Robert B.
Published: July 2019

The application of estimation theory for predicting peak ground motion is critically examined in order to be more precise in its application. Estimation theory relates peak ground motion to the duration and spectrum of the signal. Using vertical component data from the Eastern Canada Telemetered Network, at distance range of 100–1000 km, we find that a duration must be defined by the interval where the cumulative energy of the main signal increases linearly, here between 5% and 75% of the cumulative power. This duration, when used with the spectra within this window, adequately replicates observed peak motions. This duration used differs significantly from that used by Herrmann (1985) and Toro and McGuire (1987) beyond 500 km. The estimation theory is extended to estimate confidence limits on the peak motion. Finally, the relation between various spectral level estimators, linear, logarithmic, and RMS, is considered to point out the need for consistency in spectral level estimation using smooth models.
A Student’s Guide to Teleseismic Body Wave Amplitudes
Authors: Okal Emile A.
Published: July 2019

We discuss the nature of the various factors contributing to the amplitude of a teleseismic body wave in the context of a geometrical ray solution, specifically: the radiation of elastic waves into an elastic medium by a point source; the radiation patterns resulting from the orientation of the double-couple in space; the effect of propagation through a radially heterogeneous Earth, known as geometrical spreading; the effect of anelastic attenuation; the contribution of depth phases to the seismogram; and finally the influence of distance on the receiver response function. For each of these parameters, we emphasize the physical arguments underlying the exact algebraic expressions of the various factors contributing to the seismic amplitude. Finally, we discuss the extension of the geometrical ray solution to deep seismic sources.
Real-Time Analog and Digital Data Acquisition Through CUSP
Authors: Peppin William A. , Nicks Walter F.
Published: July 2019

The University of Nevada Seismological Laboratory operates an array of 60 analog short-period and 10 three-component digital telemetered seismic stations, 90 data traces in all, in Nevada and eastern California. Formerly, the seismic data streams were recorded and processed on three separate computers running disparate software and writing incompatible data formats which made access to the digital data quite cumbersome. These systems were recently replaced by a single computer system, a MicroVAX II running VAX/VMS, together with Generic CUSP (Caltech -U.S.G.S. Seismic Processing System), a controlled software system from the U.S.G.S. in Menlo Park. Telemetered digital data are stored simultaneously in two ways, unique to this network. First, these digital data are brought asynchronously into the computer using a standard direct-memory access interface and recorded continuously on an Exabyte 8-mm helical-scan tapedrive. Second, the digital data are passed through a D to A converter and intermixed with the incoming analog data stream used for routine network processing. This analog data stream is then itself digitized and presented to the computer. In this way, calibrated digital waveforms are available in the routine data processing stream, now entirely comprised of digital waveforms, used to locate earthquakes. At the same time, this allows easy access to these data in research applications involving the processing of seismic waveforms.
Structure of the Reelfoot Rift As Interpreted From 2-D Magnetotelluric Models
Authors: Stanley William D. , Rodriguez Brian D.
Published: July 2019

The results of magnetotelluric (MT) surveys reveal structures associated with the Reelfoot rift, including an axial high-resistivity structure that may be related to intrusions in the central part of the rift or to a previously unrecognized horst. The axis of this resistivity high generally follows the central part of the Reelfoot rift, but its orientation is offset several degrees from the enigmatic Blytheville arch. The MT structural high follows the main part of a northeast-trending seismicity belt, but in the New Madrid, Missouri area electrical structures are more complicated. In this northern part of the study area, the strike of resistivity structures determined from the MT data indicate a nearly north-south direction, rather than the N45°E direction indicated for most of the data. If the axial high-resistivity structure represents a horst, then it may form an interior divide between thick shale basins. Faults bounding the proposed horst may be a controlling factor for the northeast trending seismic zone.
Preliminary Shallow Seismic Reflection Survey of Crowley’s Ridge, Northeast Arkansas
Authors: VanArsdale Roy B. , Schweig Eugene S. , Kanter Lisa R. , Williams Robert A. , Shedlock Kaye M. , King Kenneth W.
Published: July 2019

Five high resolution seismic reflection lines (24 channel Mini-Sosie data with 1 s record length) were acquired across the margins of Crowley’s Ridge in northeast Arkansas during the summer of 1990 to test the hypothesis that Crowley’s Ridge is fault bounded. Three of the lines traversed the margins of the northern segment of the ridge near Jonesboro, Arkansas, and the other two were located south of Jonesboro across the margins of the southern segment. All five lines revealed subsurface faulting of the Paleozoic through Eocene (Wilcox) sections beneath the ridge margins. The data did not resolve the uppermost 0.1 s of two way travel time so it is not possible to determine if the Pliocene and younger sediments have been faulted. Thus, we can not determine if the ridge truly owes its topographic relief to fault displacement or if Tertiary faulting controlled subsequent Quaternary river incision. At one site, however, it does appear that the ridge margin is a fault scarp because the ridge height is the same as the structural relief on the ridge-bounding fault and fault displacement can be traced into the shallowest reflectors (0.15 s).
The Damage Potential of Eastern North American Earthquakes
Authors: Greig Glenn L. , Atkinson Gail M.
Published: July 2019

We compare the damage potential of three recent eastern North American (ENA) earthquakes (Nahanni, 1985; Saguenay, 1988; and Mont Laurier, 1990) to that of the 1989 Loma Prieta, California earthquake. The Saguenay and Mont Laurier events were noteworthy due to their unusually high stress drops. The comparisons are based on synthetic ground motion records generated by the stochastic method, using source and attenuation models that were derived from actual records for each event. Damage potential is characterized by inelastic strength demand spectra, obtained by analyzing the response of nonlinear oscillators to each record. There is a strong similarity between the inelastic spectra and the more familiar elastic response spectra, although some significant differences are observed. Comparisons between events show that a moderate high-stress ENA earthquake, like Saguenay, can be as damaging to high-frequency structures as a major California earthquake.
A Note on the Influence of Site Conditions on Ground Motion Values Observed for the Southeastern Illinois Earthquake of June 10, 1987
Authors: Zhang M. , Street R. , Harris J. , Drnevich V.P.
Published: July 2019

Site conditions (i.e., depth to bedrock and intermediate horizons within the soil column, and the shear wave velocities of-the soils and bedrock) have been investigated using and SH-wave velocity data at eight sites in Illinois and Indiana where the June 10, 1987, southeastern Illinois earthquake was recorded on blast monitors. The site effects have been calculated using the site conditions and the one dimensional response analysis program WAVES (Hart and Wilson, 1989), and it was found that the site conditions caused the peak particle accelerations to be amplified by a factor of 2.7 to 4.8. It is suggested that the records of ground motions obtained at sites not on rock be considered inadequate for usage at other sites unless accompanied by a quantitative description of the site conditions.
Did (Or Will) Fluid Injection Cause Earthquakes? - Criteria for a Rational Assessment
Authors: Davis Scott D. , Frohlich Cliff
Published: July 2019

Occasionally, the injection of fluids into deep wells causes or triggers earthquake activity. We propose two lists of yes-or-no questions to assess 1) whether an ongoing injection project has induced an earthquake that has already occurred; or 2) whether a proposed injection project is likely to induce a nearby earthquake. The answers to these questions form a descriptive profile of the injection project that facilitates comparison with other projects. To illustrate the application of these questions, we describe the answers in detail for the first set of questions at two sites: 1) the Rocky Mountain Arsenal near Denver, Colorado, where three significant earthquakes occurred in 1967; and 2) an injection site near Painesville, Ohio, near the epicenter of an earthquake that occurred 31 January, 1986. We also present a table of answers to these questions for several additional sites, and review other factors that may affect the potential for induced, seismic activity. The profiles of injection sites presented herein provide a convenient tool for deciding whether an injection site more closely resembles other sites where injection does, or does not induce earthquakes.
Attenuation of Multiphase Surface Waves in the Basin and Range Province Part II: The Fundamental Mode
Authors: Mitchell Brian J. , Xie Jai-kang , Lin Wen-jack
Published: July 2019

In order to investigate the large errors which sometimes characterize fundamental-mode attenuation coefficient determinations, we have made many such determinations in the Basin and Range province and have plotted particle motion for the observed three-component seismograms. Rayleigh wave attenuation coefficient values determined for four two-station paths across the Basin and Range province fluctuate between about −2.0 × 10−3km−1 and +3.0 × 10−3km−1 at periods between 6 and 33 s. Partide motion plots indicate that many of those determinations are contaminated by arrivals from non-great circle paths and from waves generated at heterogeneities along the path, factors which lead to systematic errors in the measured attenuation coefficient values. Attenuation coefficient determinations for the path MNV to ELK, which is within 20° of being normal to the structural trends of the Sierra Nevada and Great Valley, are, however, relatively free from such contamination. Mean values for that path decrease rapidly with period from about 3.0 × 10−3 to about 0.7 × 10−3km−1 between 6 and 10 s and then decrease slowly to about 0.3 × 10−3km−1 at 33 s. Standard deviations range between 0.2 × 10−3 and 0.3 × 10−3km−1 for most of the period range, but increase to about 0.4 × 10−3 at periods between 6 and 8 s. These results indicate that careful screening, based upon criteria such as three-dimensional particle motion, are necessary to obtain surface wave attenuation data of sufficient quality to use for inverting for crustal anelasticity in complex regions.
Earthquake Recurrence Rates in the Central Atlantic United States
Authors: Howell B.F.
Published: July 2019

The seaboard area from Rhode Island to Maryland has not experienced an earthquake larger than magnitude 5.1 since European settlement. The rate of occurrence of small earthquakes for the last 200 years suggests that the 500-year earthquake might be about magnitude 5.2. An earthquake comparable to the 1886 Charleston, S. C. earthquake (magnitude 6.7) has an average recurrence period calculated to exceed ten thousand years. The effect of variability in the seismic activity rate and possible incompleteness of the record of activity makes the accuracy of recurrence estimates for this region uncertain.

Authors: Lal Roshan , Kumar Pratik
Published: July 2019

Background: Many of the ILDs are difficult to differentiate on clinical examination and history as they have similar clinical features. Symptom complex is not beyond that of respiratory symptoms. The objective was to study the clinical picture and spirometry pattern of the patients having interstitial lung disease.Methods: Hospital based cross sectional study was carried out among 73 cases of ILDs. Data related to history, clinical examination was recorded. Six minute walk test and spirometry was carried out. The data was analysed using proportions.Results: Incidence of Idiopathic pulmonary fibrosis (IPF) increased with age. Exertional dyspnea (100%) and cough (95.9%) were the commonest presenting symptoms amongst ILD patients. End inspiratory fine crackles (95.1%) and clubbing (67.1%) are the predominant clinical signs. Mean BMI of various ILDs patients were 24.86±8.2 Kg/m² in NSIP followed by 22.9±4.6 in sarcoidosis 21.9±6.4 and 20.8±3.94 in IPF and in Cryptogenic Organizing Pneumonias 19.34±1.8 Kg/M².

Authors: Solanke Sachin N. , Pohekar Abhay S. , Pohekar Jayshree A.
Published: July 2019

Background: The global incidence of dengue has grown dramatically in recent decade. Half of world’s population is now at risk. India represents significantly a larger burden, accounting for nearly 34% of the global burden of dengue infection. Dengue infection needs to be addressed as a single disease with different clinical presentations ranging from asymptomatic conditions to severe clinical courses that may lead to high morbidity and mortality.Method: This was retrospective observational study carried out during period of July 2017 to April 2018, to study clinical profile and laboratory parameters in dengue fever patients. Confirmed dengue cases having NS1 positive or IgM positive or having both NS1 and IgM positive or dengue ELISA reactive, having minimum one CBC reports done and not having other confounding factor such as co-infection, bone marrow diseases etc. that may altered clinical and laboratory results are included in study. Statistical analysis was done by SPSS software version 18.0.Results: Out of 48 confirmed dengue cases maximum patients 58.33% was from young age group (21 to 40 years) with M:F ratio was 2.43:1. Fever was found in 100% patients, in order of frequency followed by headache, bodyache, abdominal pain, weakness, retro-orbital pain, anorexia, dry cough, back pain, nausea, diarrhoea, vomiting, rash, joint pain, itching and malena.NS1was positive in 41.67% cases, dengue ELISA in 31.25%, IgM was positive in 20.83% cases, and both NS1 and IgM positive were in 4.17% cases. TLC count was low 35.42%, high in 12.50% of cases and remaining had normal TLC count. Platelet count was ranged between normal platelet counts to thrombocytopenia. One case had platelet count less than 20000. Out of 48 patients, 2 (4.17%) had malena.Conclusion: In this study, fever was found in all patients, and headache, body ache and weakness were common symptoms, but significant number of patients also had gastroentstinal and respiratory symptoms like abdominal pain, nausea, diarrhea, vomiting and dry cough. TLC count ranging from normal TLC, leukopenia to leucocytosis. Large number of patients had low platelet count that shows dengue fever had varied clinical presentation.

„Nie sierdźże się, wietrze…, hulaj sobie, niebożę, …” (kоncept „wiatr” w „małej prozie” Wasyla Tkaczuka)

Wiatr – to jeden ważnych obok słońca, księżyca, chmur, mrozu czy nieba konceptów wchodzących w skład konceptosfery Wasyla Tkaczuka – ukraińskiego nowelisty lat 30. XX w. Koncept wiatr funkcjonuje w systemie pozostałych konceptów, treści których zakodowane są w kulturowo-mentalnościowej przestrzeni narodu i jednocześnie w indywidualno-autorskim obrazie świata. Przeżycia bohaterów zharmonizowane są w najwyższym stopniu z elementami świata przyrody. Tak więc czytelnik paralelnie do działań bohaterów śledzi „poczynania” wiatru czy wspomnianych wyżej słońca, księżyca, chmur, mrozu, nieba. Zgłębienie jednego z ważnych konceptów w prozie Wasyla Tkaczuka jest tym bardziej zajmujące, iż mało znana spuścizna twórcza nowelisty wciąż czeka na należne jej miejsce w kanonie ukraińskiej literatury.

Published: July 2019

Objectives:
The aim of the
study was to evaluate the oxidative stress level in patients, diagnosed with Helicobacter pylori infection, using a
novel marker (thiol/disulphide homeostasis) and to compare the level in infected
individuals with that in healthy volunteers. Methods: A total of 60 patients diagnosed with gastritis, erosive gastritis or ulcer by endoscopy were included and biopsied.
The 30 patients diagnosed with H. pylori and 30 healthy individuals were enrolled. Medical histories, physical examination results, body mass index (BMI), hemogram, free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating
hormone (TSH), urea, creatinin, aspartate aminotransferase (AST), alanine
aminotransferase (ALT), albumin, total cholesterol, triglycerides, high density lipoprotein (HDL), low density lipoprotein) LDL and thiol/disulphide levels obtained in the study groups were
compared. Results: There was no significant difference between
the total thiol, native thiol,
disulphide/native thiol and dissulphide/total thiol ratios of the patient and
control group. When the H. pylori patients were stratified by
endoscopic evaluation as having mild (superficial gastritis or normal
appearance) or severe (ulcer or erosive areas)
symptoms, there were significant differences in disulphide, disulphide/native thiol, disulphide/total thiol and native thiol/total
thiol levels. We also observed BMI and the total, native thiol levels of H. pylori patients were inversely
related.( r: 0.562, p = 0.001; r: 0.0552,
p = 0.002).

Conclusions: Thiol/disulphide homeostasis is likely to differ with
both duration and severity of H. pylori
infection. Further investigations are needed to investigate the effect of H. pylori on oxidative stress.
El amor en la novela griega

La novela griega de amor y aventuras, mejor conocida como erótica, no tiene un patrón estructural fijo en relación con el tema amoroso, por lo que cada autor lo maneja de diversa manera. En este texto daré cuenta de las variantes en el manejo del tema amoroso, que va desde el flechazo amoroso que hace surgir este sentimiento de forma súbita, hasta un lento cortejo que lleva a conquistar al ser amado. Centraré mi análisis en las obras de Longo, Jenofontede Éfeso y Aquiles Tacio. De igual modo, con el afán de destacar la importancia del tema amoroso, voy a analizar algunas digresiones insertas en el desarrollo de la trama que lo abordan de manera tangencial. Me refiero a las emociones del hombre ante el amor: la mirada y el beso, y ciertas técnicas de conquista, incluido el amor homosexual, para finalizar con las situaciones en que se pone a prueba la castidad y fidelidad de los protagonistas. A partir del análisis realizado,podemos concluir que el eros pasional de los protagonistas se presenta como base de un lazo conyugal que es sometido a un sinnúmero de pruebas durante las cuales se transforma, desde la pasión arrasadora inicial, en algo estable y permanente, que se ofrece como un modelo a seguir para el público de la novela.
La jupiterización de los signa militaria: cambios simbólicos en la estructura socio-militar romana
Authors: Llantén Quiroz Nicolás Fernando , Penna Órdenes Nicolás Eduardo

El presente artículo propone una nueva interpretación con respecto al simbolismo político-religioso de las enseñas militares romanas de fines del siglo II a. C. donde la eliminación de cuatro de sus cinco estandartes estaría vinculada estrechamente con las reformas para la profesionalización del ejército llevadas a cabo por Cayo Mario. En este caso la supervivencia del estandarte del águila iría en concordancia con la supremacía de Júpiter por encima de Marte, quien simbólicamente en su origen fue también un dios agrícola cuya fisonomía religiosa encarnaría el ideal de la dualidad de campesino-soldado que se buscó eliminar por el nuevo soldado profesional.

Anticancer Activity of Selective and Non-Selective Beta Adrenoreceptor Blockers against Non-Small Cell Lung Cancer Cell Lines
Authors: Sidorova Marina , Petrikaite Vilma
Published: July 2019

Beta adrenoblockers is a large class of drugs mainly used to manage abnormal heart rhythms. Over the last couples of decades, the anticancer effects of these compounds has been extensively studied. There is much evidence about their activity in non-small cell lung, pancreatic, breast, colorectal, prostate and ovarian cancer. However, the mechanism of beta blockers anticancer activity is still not known, and more detailed studies are needed. The aim of our study was to evaluate the anticancer activity of beta adrenoblockers in non-small cell lung cancer cell lines A549 and H1299. In order to find the relationship with their selectivity to beta adrenoreceptors, in our study we used selective (atenolol, betaxolol, esmolol, metoprolol) and non-selective (pindolol, propranolol and timolol) beta blockers. The effect on cell viability was evaluated by MTT assay and the activity on cell ability to form colonies was tested by clonogenic assay. The type of cell death was evaluated by cell double staining with Hoechst 33342 and Propidium iodide. The most active adrenoblockers against both tested cancer cell lines were propranolol and betaxolol. They completely inhibited lung cancer cell colony formation at 90% of EC50 (half maximal effective concentration) value. Most tested compounds induced cell death through apoptosis and necrosis. In A549 cell lines apoptosis was mainly induced while in H1299 cell line compounds induced both apoptosis and necrosis. There was no correlation established between beta adrenoblocker anticancer activity and their selectivity to beta adrenoreceptors.

Objectives. Calprotectin, a protein released by neutrophils, has been used in many studies as a biomarker showing the presence of inflammation. In this study, it was aimed to investigate the relationship between serum calprotectin level and response to the treatment of idiopathic sudden sensorineural hearing loss (ISSHL).Methods. The present study is a prospective, cross-sectional historical cohort study. The study group consisted of 44 patients with ISSHL, and the control group consisted of 41 healthy volunteers without ear pathology. At the same time, patients in the study group were divided into three groups according to the response to ISSHL treatment (recovered, partially recovered, unrecovered). The relationship between the groups was statistically evaluated in terms of serum calprotectin levels.Results. The mean serum calprotectin value was 75.67±19.48 ng/mL in the study group and 50.24±29.14 ng/mL in the control group (P=0.001). Serum calprotectin value according to the severity of hearing loss in the mild, moderate and severe was 66.20±8.82, 70.35±16.77, and 91.23±19.73 ng/mL, respectively. Serum calprotectin value in the severe group was significantly higher compared to the moderate and mild groups (P=0.004, P=0.001, respectively). Serum calprotectin value according to the treatment response in the recovered, partially recovered and unrecovered groups was 63.36±11.54, 80.17±12.06, and 85.33±22.33 ng/mL, respectively. Serum calprotectin value in the recovered group was significantly lower compared to the partially recovered and unrecovered groups (P=0.002, P=0.001, respectively).Conclusion. Serum calprotectin value informs the clinician about both the severity of hearing loss and the response to treatment. Hence, serum calprotectin can be used as an important biomarker in ISSHL patients for the determination of the prognosis of disease.

AICLE (Aprendizaje Integrado de Contenidos y Lenguas Extranjeras) es el enfoque oficial europeo para la educación bilingüe, auspiciado por la Comisión Europea y fomentado por una cantidad ingente de investigación e implementación en todos los niveles educativos. Sin embargo, AICLE necesita de más investigación en el aula e interacciones que ofrezcan datos que nos indiquen en qué contextos y bajo qué condiciones específicas las acciones educativas son o no eficaces. Es en esta línea (innovación educativa e interacción en el aula) en la que entendemos que la formación inicial del profesorado en el ámbito de la educación bilingüe ha de estar necesariamente ligada a la formación permanente del profesorado y a la praxis en el aula que proporciona el profesorado en ejercicio.El objetivo esencial de este artículo consiste en establecer el vínculo entre profesorado universitario, profesorado en ejercicio, profesorado en formación (a tres niveles: Grado, Máster y Doctorado) y los CEP de Córdoba y provincia para diseñar una estructura de formación recíproca y cuidadosamente planificada, que contribuya a mejorar la calidad de la educación bilingüe a través del intercambio de prácticas de innovación educativa que fomenten la interacción y el aprendizaje en acción.
