Актуальность. Лечение трофических язв до настоящего времени является одной из сложнейших задач. В условиях нарушенной трофики в ране крайне замедлен синтез тканевых элементов, поэтому представляется целесообразным использовать средства, стимулирующие регенерацию.Цель исследования: оценить эффективность применения различных способов стимуляции регенерации в длительно незаживающих ранах.Материалы и методы исследования. С целью изучения клинической эффективности применения комбинации концентрированной суспензии тромбоцитов и нативного нереконструированного коллагена для местного лечения трофических язв проведено сравнительное исследование с контролем в параллельных группах. Пациенты случайным образом разделены на основную группу, в которую вошли пациенты, у которых для местного лечения трофических язв использовали комбинацию концентрированной суспензии тромбоцитов и нативного нереконструированного коллагена и 3 контрольные группы: в первой - в комплексном лечении пациентов использовали современные перевязочные средства, во второй - в комплексной топической терапии применяли только коллагенсодержащие препараты, в третью контрольную группу вошли пациенты, у которых в комплексной топической терапии использовали обогащенную тромбоцитами плазму. Процесс заживления оценивали с помощью измерения язвенного дефекта, состояния кожи вокруг ран, бактериологического исследования раневого отделяемого, цитологического и патолого-гистологического исследований тканей раны, инструментальных методов исследований.Результаты. Применение комбинации концентрированной суспензии тромбоцитов и нативного нереконструированного коллагена статистически достоверно ускоряет эпителизацию раневой поверхности, эффективнее стимулирует грануляции, существенно снижает негативные ощущения в ране.Ключевые слова: венозные трофические язвы, концентрированная суспензия тромбоцитов, коллаген.

Published: February 2017

Artykuł prezentuje wyniki multidyscyplinarnych badań neoholoceńskicj pokrywy stokowej odkrytej w zlewni Neru w Polsce Środkowej. Badania z zakresu archeologii środowiskowej zrealizowane zostały w ramach prac archeologicznych prowadzonych na stanowisku Szynkielew. Przyniosły one odkrycie na obszarze stanowiska bogatych reliktów intensywnego osadnictwa grup ludzkich od epoki brązu po wczesne średniowiecze. Przeprowadzone badania geoarcheologiczne pokryw stokowych oraz aluwiów facji pozakorytowej umożliwiły rozpoznanie warstw kulturowych, gleb kopalnych oraz deluwiów rozwiniętych na zboczach doliny, a także miąższej pokrywy osadów pozakorytowych w dnie doliny Dobrzynki. W obrębie pokrywy stokowej rozpoznane zostały deluwia piaszczyste, a także zawierające domieszki próchniczne tzw. deluwia glebowe. Akumulacja osadów stokowych zachodziła w warunkach silnej antropopresji, co potwierdzają występujące w nich artefakty i ekofakty, które ponadto umożliwiły precyzyjne określenie wieku odkrytych deluwiów. Inicjowanie oraz rozwój procesów stokowych zostały skorelowane z fazami antropogenicznego przeobrażania środowiska naturalnego. Wyróżniono dwie główne fazy wzmożenia tych procesów, których wiek określono na środkową epokę brązu oraz wczesne średniowiecze. Czas akumulacji pokrywy aluwiów pozakorytowych także określony został na wczesne średniowiecze. Wczesnośredniowieczna faza intensywnych procesów geomorfologicznych miała miejsce w XII wieku, po włączeniu „opola chropskiego” w obręb włości kapituły krakowskiej.
PRISTUP EPISTEMOLOGIJI, KNJIŽEVNOSTI I PJESNIKOVOJ POLITICI

Published: February 2017

Moja je početna pretpostavka da je shvaćanje ili doxa što smo ga naslijedili od Visokoga modernizma zakazalo tokom, i upravo zbog, postmodernističkog i postfordističkog trijumfa grabljivog kapitalizma. Time je obuhvaćena i masovna zlouporaba modernih nauka u ratovima i osiromašavanju naroda, kao i uništavanje intelektualnih pretpostavki kako praktične ljevice u doba staljinizma, koje se manifestovalo u katastrofama posle 1968. i 1989, tako i pravog slobodoljubivog liberalizma.
Ta široka tema zaslužuje zasebnu obradu, premda uz oštro odbacivanje postmodernističke „slabe misli“ napuštanja razuma. U ovome eseju predočavam, najprije, što bi mogle biti osnove i značajni vidovi epistemologije, grane filozofije koja postavlja pitanje kako znamo ono što (mislimo da) znamo, te predlažem kako se orijentirati u njoj (krećući se ka „mekom“ skepticizmu). Potom pravim paralele između nauka i umjetnosti, uključujući i njihova institucionalna uporišta, osobito u pogledu naracije. Završavam kratkim osvrtom na to kako umjetnost i pjesnička spoznaja mogu intervenirati u politici slobode i opstanka: u značajnoj mjeri, ali indirektno.
POZITIVNOST ETNIČKIH STEREOTIPA PREMA ETNIČKIM MANJINAMA KOD UČENIKA OSNOVNIH I SREDNJIH ŠKOLA U VOJVODINI

Published: February 2017

Osnovni problem istraživanja je kako izgledaju stereotipi adolescenata prema pojedinim etničkim grupama koje žive na teritoriji Vojvodine, kao i kakva je direkcija tih stereotipa. Uzorak je činilo 804 učenika završnih razreda osnovnih škola i sva četiri razreda srednjih škola sa teritorije Vojvodine. Kao instrument za utvrđivanje stereotipa prema etničkim grupama koršćena je modifikovana verzija Kac-Brejlijevog postupka. Osim toga, procenjivana je i poređena pozitivnosti stereotipa prema različitim etničkim grupama. U istraživanju su ispitivani stereotipi prema pet etničkih grupa koje žive na teritoriji Vojvodine (Hrvati, Mađari, Romi, Albanci i Crnogorci). Rezultati pokazuju da postoje jasne stereotipne slike svih grupa, kao i da se pozitivnost stereotipa značajno razlikuje između njih. Najnegativnji stereotipi su utvrđeni prema Albancima i Romima, dok su stereotipi prema druge tri grupe pozitivniji. Utvrđene su razlike u pozitivnosti stereotipa u odnosu na pol (dečaci imaju negativnije stereotipe prema svim grupama, osim prema Crnogorcima gde nema razlike), uzrast ispitanika (razlike postoje samo kod stereotipa prema Romima-mlađi ispitanici imaju negativnije stereotipe) i kod interakcije ove dve varijable (samo kod stereotipa prema Romima nema razlike u odnosu na pol kod učenika srednje škole). Obrazovanje roditelja nije se pokazalo kao relevantan faktor pozitivnosti stereotipa.

Core Ideas
The Lower Mississippi River Basin (LMRB) is agriculturally important and ecologically unique.
The Delta‐Flux network will coordinate the activities of 17 eddy covariance towers.
The network addresses the need for scaled C and water cycle observations.
The network aims to promote sustainable, climate‐smart land management.
Delta‐Flux is open to collaborators from strategic sites and relevant disciplines.
Networks of remotely monitored research sites are increasingly the tool used to study regional agricultural impacts on carbon and water fluxes. However, key national networks such as the National Ecological Observatory Network and AmeriFlux lack contributions from the Lower Mississippi River Basin (LMRB), a highly productive agricultural area with opportunities for soil carbon sequestration through conservation practices. The authors describe the rationale to create the new Delta‐Flux network, which will coordinate efforts to quantify carbon and water budgets at seventeen eddy covariance flux tower sites in the LMRB. The network structure will facilitate climate‐smart management strategies based on production‐scale and continuous measurements of carbon and water fluxes from the landscape to the atmosphere under different soil and water management conditions. The seventeen instrumented field sites are expected to monitor fluxes within the most characteristic landscapes of the target area: row‐crop fields, pasture, grasslands, forests, and marshes. The network participants are committed to open collaboration and efficient regionalization of site‐level findings to support sustainable agricultural and forestry management and conservation of natural resources.
Ruminant Urine Increases Uptake but Decreases Relative Recovery of Nitrogen by Smooth Bromegrass
Authors: Snell Laura K. , Guretzky John A. , Jin Virginia L. , Drijber Rhae A. , Mamo Martha 
Published: February 2017

Core Ideas
Forage mass and crude protein increase with N fertilizer rates up to 160 lb/acre in smooth bromegrass pastures.
Smooth bromegrass responds even more so to urine from livestock grazing.
Managers should encourage even grazing distribution across time to minimize nutrient losses from pastures.
Understanding pasture responses to urine deposition remains limited. From 2011 to 2012, we investigated the effects of urine collected from ruminants and applied to N‐fertilized (0, 40, 80, 120, and 160 lb N/acre) plots (25 sq ft) of smooth bromegrass (Bromus inermis Leyss.) in eastern Nebraska. Urine was spread evenly across plots at both a volume (0.6 qt/sq ft) and N content (0.26 and 0.24 oz/qt) that simulated ruminant urine deposition in spring and resulted in an additional supply of 425 and 392 lb N/acre in 2011 and 2012, respectively. Control plots received the same volume of distilled water but no additional N. Response variables included forage mass, crude protein (CP) concentration, N uptake, apparent N recovery (ANR), and N use efficiency (NUE). In 2011, forage mass, CP, and N uptake increased linearly with N fertilizer rate and were 80, 30, and 135%, respectively, greater in urine‐treated than in distilled water–treated plots. In 2012, drought limited forage mass, and only urine impacted N responses. Apparent N recovery averaged 42% in urine‐treated and 63% in distilled water–treated plots in 2011 but did not differ between treatments in 2012, averaging 24%. Values for NUE did not differ among treatments and averaged 13.0 lb dry matter (DM)/lb N fertilizer applied in 2011 and 6.5 lb DM/lb N fertilizer applied in 2012. In years with favorable precipitation, producers can expect forage mass and CP to increase with fertilizer applications up to 160 lb N/acre. Optimum rates, though, would depend on production goals, nutritional needs of livestock, and fertilizer, land, and cattle prices.
Management Options for Contaminated Urban Soils to Reduce Public Exposure and Maintain Soil Health
Authors: Obrycki John F. , Basta Nicholas T. , Culman Steven W. 
Published: February 2017

Soil management in urban areas faces dual challenges of reducing public exposure to soil contaminants, such as lead (Pb) and polycyclic aromatic hydrocarbons, and maintaining soil function. This study evaluated three management options for an urban lot in Cleveland, OH, containing 185 to 5197 mg Pb kg−1 and 0.28 to 5.50 mg benzo(a)pyrene kg−1. Treatment options included: (i) cap the site with a soil blend containing compost and beneficially reused dredged sediments, (ii) mix compost with the soil, and (iii) mix compost and sediments with the soil. The soil blend cap reduced surface soil Pb to 12.4 mg Pb kg−1 and benzo(a)pyrene content to 0.99 ± 0.41 mg kg−1. Aggregate stability for 2‐ to 0.25‐mm aggregates in the soil blend cap was 13% compared with the 38% aggregate stability in the urban soil. Mixing compost with the soil reduced benzo(a)pyrene content, but sample variability indicated that elevated spots likely remained exposed at the surface. Compost addition diluted soil Pb and increased aggregate stability to 60%. Mixing compost and sediments with the soil was the only management option accomplishing both management goals of reducing surface soil contaminants and maintaining soil health. For this combined mixing option, aggregate stability was 37%, soil Pb was 15 mg kg−1, and benzo(a)pyrene was 0.99 ± 0.09 mg kg−1. Food‐grade oil addition did not increase benzo(a)pyrene degradation. Future studies should evaluate how incorporating soil blends in different soil types with a range of contaminants may offer a suitable long‐term management option for urban soil contaminants.Core Ideas
Soil blend incorporation maximized soil health and human health benefits.
Soil capping may cover contaminants but reduced surface soil aggregate stability short term.
Compost addition maintained surface aggregate stability and diluted Pb surface contamination.
Incorporating soil blends offers a potential long‐term urban soil management solution.
Impacts of Road Salting on Water Quality in Fractured Crystalline Bedrock

Published: February 2017

Many rural communities depend on bedrock wells as a primary water source, which raises the issue as to whether increasing amounts of salt application are affecting bedrock water quality and to what degree. Through wellbore profiling, this study investigated changes in specific conductance in two crystalline bedrock wells at the University of Connecticut in Storrs, CT, from 2003 to 2016, with particular emphasis on the impacts of increased salt application with a change in deicing practices at the university after 2009. Hourly specific conductance measurements were collected in 2014 to determine how water source may affect wellbore concentrations seasonally. Chloride was found to be highly persistent in the bedrock, with concentrations consistently increasing from 2003 to 2016 despite year‐to‐year variations in salt application. A dramatic increase in chloride occurred in the wellbores in response to the change in deicing practices, with an immediate response in fractures having a direct connection to the overburden. In light of the long‐term implications of road salting on subsurface chloride contamination, this study argues that consideration be given to deicing management strategies to reduce road salt contamination.Core Ideas
Chloride is highly persistent in groundwater in crystalline bedrock.
Chloride in bedrock wells increased in response to a change in deicing practices.
Stored chloride contributes to wellbore concentrations beyond the salting season.
Alzheimer's Disease and NQO1: Is there a Link?
Authors: Chhetri Jamuna , King Anna E. , Gueven Nuri 
Published: February 2017

Background:
Alzheimer's disease (AD) is a neurodegenerative disease characterised by a
progressive decline in cognitive function and represents a major healthcare challenge worldwide. Increasing
evidence indicates that mitochondrial dysfunction mediated oxidative stress plays a significant
role in the pathophysiological process of AD. Therefore, the physiological activation of antioxidant
enzymes that respond to increased oxidative stress is thought to prevent neuropathology. One of those
endogenous defences is NADPH quinone oxidoreductase 1 (NQO1). NQO1 is a cytosolic homodimeric
flavoprotein that catalyses the two-electron reduction of quinones and related molecules aimed at increasing
their solubility and excretion. In line with its role as a phase II stress response protein, altered
NQO1 expression is associated with several pathological conditions and disorders including AD.

Conclusion:
This review summarizes the association between NQO1 and AD pathology. Understanding
this association will provide further insight into the pathogenesis of the disease. More importantly,
recent interest in drugs that affect NQO1 expression or its activity provides hope that this approach
could lead to novel therapeutic options for the treatment of AD.

The Structure of the Distant Kuiper Belt in a Nice Model Scenario

Published: February 2017

Abstract
This work explores the orbital distribution of minor bodies in the outer Solar System emplaced as a result of a Nice model migration from the simulations of Brasser and Morbidelli. This planetary migration scatters a planetesimal disk from between 29 and 34 au and emplaces a population of objects into the Kuiper Belt region. From the 2:1 Neptune resonance and outward, the test particles analyzed populate the outer resonances with orbital distributions consistent with trans-Neptunian object (TNO) detections in semimajor axis, inclination, and eccentricity, while capture into the closest resonances is too efficient. The relative populations of the simulated scattering objects and resonant objects in the 3:1 and 4:1 resonances are also consistent with observed populations based on debiased TNO surveys, but the 5:1 resonance is severely underpopulated compared to population estimates from survey results. Scattering emplacement results in the expected orbital distribution for the majority of the TNO populations; however, the origin of the large observed population in the 5:1 resonance remains unexplained.
Probing the Anisotropy of the Milky Way Gaseous Halo-II: Sightline toward Mrk 509
Authors: Gupta A. , Mathur S. , Krongold Y. 
Published: February 2017

Abstract
Hot, million degree gas appears to pervade the Milky Way halo, containing a large fraction of the Galactic missing baryons. This circumgalactic medium (CGM) is probed effectively in X-rays, both in absorption and in emission. The CGM also appears to be anisotropic, so we have started a program to determine CGM properties along several sightlines by combining absorption and emission measurements. Here we present the emission measure close to the Mrk 509 sightline using new Suzaku and XMM-Newton observations. We also present new analysis and modeling of Chandra HETG spectra to constrain the absorption parameters. The emission measure in this sightline is high, EM = 0.0165 ± 0.0008 ± 0.0006 cm−6 pc, five times larger than the average. The observed O vii column density N(O vii)

cm−2, however, is close to the average. We find that the temperature of the emitting and absorbing gas is the same: logT(K) = 6.33 ± 0.01 and logT(K) = 6.33 ± 0.16 respectively. We fit the observed column density and emission measure with a β-model density profile. The central density is constrained to be between n
0 = 2.8–6.0 × 10−4 cm−3 and the core radius of the density profile has a lower limit of 40 kpc. This shows that the hot gas is mostly in the CGM of the galaxy, not in the Galactic disk. Our derived density profile is close to the Maller & Bullock profile for adiabatic gas in hydrostatic equilibrium with an NFW dark-matter potential well. Assuming this density profile, the minimum mass of the hot CGM is

Investigating the Wave Nature of the Outer Envelope of Halo Coronal Mass Ejections
Authors: Kwon Ryun-Young , Vourlidas Angelos 
Published: February 2017

Abstract
We investigate the nature of the outer envelope of halo coronal mass ejections (H-CMEs) using multi-viewpoint observations from the Solar Terrestrial Relations Observatory-A, -B, and SOlar and Heliospheric Observatory coronagraphs. The 3D structure and kinematics of the halo envelopes and the driving CMEs are derived separately using a forward modeling method. We analyze three H-CMEs with peak speeds from 1355 to 2157 km s−1; sufficiently fast to drive shocks in the corona. We find that the angular widths of the halos range from 192° to 252°, while those of the flux ropes range between only 58° and 91°, indicating that the halos are waves propagating away from the CMEs. The halo widths are in agreement with widths of Extreme Ultraviolet (EUV) waves in the low corona further demonstrating the common origin of these structures. To further investigate the wave nature of the halos, we model their 3D kinematic properties with a linear fast magnetosonic wave model. The model is able to reproduce the position of the halo flanks with realistic coronal medium assumptions but fails closer to the CME nose. The CME halo envelope seems to arise from a driven wave (or shock) close to the CME nose, but it is gradually becoming a freely propagating fast magnetosonic wave at the flanks. This interpretation provides a simple unifying picture for CME halos, EUV waves, and the large longitudinal spread of solar energetic particles.
Structure of the Heliotail from Interstellar Boundary Explorer Observations: Implications for the 11-year Solar Cycle and Pickup Ions in the Heliosheath

Abstract

Interstellar Boundary Explorer (IBEX) measurements of energetic neutral atoms (ENAs) from the heliotail show a multi-lobe structure of ENA fluxes as a function of energy between ∼0.71 and 4.29 keV. Below ∼2 keV, there is a single structure of enhanced ENA fluxes centered near the downwind direction. Above ∼2 keV, this structure separates into two lobes, one north and one south of the solar equatorial plane. ENA flux from these two lobes can be interpreted as originating from the fast solar wind (SW) propagating through the inner heliosheath (IHS). Alternatively, a recently published model of the heliosphere suggests that the heliotail may split into a “croissant-like” shape, and that such a geometry could be responsible for the heliotail ENA feature. Here we present results from a time-dependent simulation of the heliosphere that produces a comet-like heliotail, and show that the 11-year solar cycle leads to the formation of ENA lobes with properties remarkably similar to those observed by IBEX. The ENA energy at which the north and south lobes appear suggests that the pickup ion (PUI) temperature in the slow SW of the IHS is ∼107 K. Moreover, we demonstrate that the extinction of PUIs by charge-exchange is an essential process required to create the observed global ENA structure. While the shape and locations of the ENA lobes as a function of energy are well reproduced by PUIs that cross the termination shock, the results appear to be sensitive to the form of the distribution of PUIs injected in the IHS.
