Praça Kantuta: símbolo de representação, identidade e cultura boliviana na cidade de São Paulo
Authors: Dos Santos Rosineia Oliveira 
Published: December 2017

O objetivo deste artigo é explicar como os locais de cultura são estratégias para que haja mobilidade dos imigrantes bolivianos na cidade de São Paulo. Como objeto de estudo, temos a Praça Kantuta, local que é símbolo de resistência e representatividade da comunidade Boliviana na cidade. Essa comunidade tem uma realidade sociocultural em São Paulo que está em profundo reconhecimento, tanto de suas práticas religiosas e festividades em datas comemorativas quanto de demarcação de território por eles requerido. Os espaços privados tornam-se símbolos de resistência e não aceitação do estigma imposto por serem imigrantes de descendência indígena. A partir dessa realidade e da pretensão em apontar algumas especificidades do processo migratório, tal como do (a) boliviano (a) e sua recriação cultural, tal como seus entrelaçamentos com a cultura local e entender como o imigrante boliviano na cidade de São Paulo consegue se inter-relacionar, pelos locais de representação cultural por eles denominado. Por meio deste questionamento, nossa resposta é de que a Praça Kantuta é local de ressignificação simbólica desses imigrantes, que sofrem preconceito e carecem de um local em que se sintam valorizados e pertencentes à cidade de São Paulo. Este artigo foi estruturado com as bibliografias de teóricos que discutem e refletem sobre a temática da imigração e a identidade cultural na pós-modernidade. Nesse caminho, desenvolvemos um trabalho com articulação interdisciplinar.

Phosphorus (P) mobilization in agricultural landscapes is regulated by both hydrologic (transport) and biogeochemical (supply) processes interacting within soils; however, the dominance of these controls can vary spatially and temporally. In this study, we analyzed a 5‐yr dataset of stormflow events across nine agricultural fields in the lower Great Lakes region of Ontario, Canada, to determine if edge‐of‐field surface runoff and tile drainage losses (total and dissolved reactive P) were limited by transport mechanisms or P supply. Field sites ranged from clay loam, silt loam, to sandy loam textures. Findings indicate that biogeochemical processes (P supply) were more important for tile drain P loading patterns (i.e., variable flow‐weighted mean concentrations ([Cf]) across a range of flow regimes) relative to surface runoff, which trended toward a more chemostatic or transport‐limited response. At two sites with the same soil texture, higher tile [Cf] and greater transport limitations were apparent at the site with higher soil available P (STP); however, STP did not significantly correlate with tile [Cf] or P loading patterns across the nine sites. This may reflect that the fields were all within a narrow STP range and were not elevated in STP concentrations (Olsen‐P, ≤25 mg kg−1). For the study sites where STP was maintained at reasonable concentrations, hydrology was less of a driving factor for tile P loadings, and thus management strategies that limit P supply may be an effective way to reduce P losses from fields (e.g., timing of fertilizer application).Core Ideas
We used metrics to evaluate controls on edge‐of‐field phosphorus losses.
We examined a 5‐yr database of stormflow events (all seasons, including winter).
Tile P runoff trended toward being more supply limited than surface runoff.
Review: Sediment‐Related Controls on the Health of the Great Barrier Reef
Authors: Hairsine Peter B. 
Published: December 2017

Core Ideas
Linking terrestrial soil erosion to marine ecosystem degradation relies on a long chain of evidence.
Excess terrestrial erosion impacts marine ecosystems via changes to marine food webs.
A graphic summary of the spatial configuration of the sources and sinks is provided.
Increased management of near‐coastal sediment sources and terrestrial sediment sinks is appropriate.
Research needs include techniques for enhancing sediment trapping, response times, and nutrient tracking.
Linking terrestrial soil erosion to the degradation of marine ecosystems relies on a long chain of evidence. Here, this chain of evidence is reviewed for Australia's Great Barrier Reef and its catchments. Excessive sediment delivery to the marine environment is one component of an interlinked group of stressors that include coral bleaching, damage by storms, and plagues of crown‐of‐thorns starfish. Sediment and the pollutants they carry are one of the drivers of marine ecosystem decline and adversely impact recovery following disturbance by other stressors. Significantly, a portion of the N species carried by fine sediment in the freshwater system is released in the marine environment, thereby perturbing marine ecology. Available controls on sediment and pollutant delivery are hillslope erosion rates, gully and streambank erosion rates, sediment deposition rates in sediment sinks including footslopes, floodplains, and water reservoirs, and the application rates of pesticides and fertilizers. By reducing sediment fluxes through the combined strategies of erosion control and deposition enhancement, near‐ and offshore impacts can be reduced. Gully and streambank erosion are more significant sources of fine sediment than hillslope erosion. Fertilizer and non‐fertilizer N and pesticides carried by sediment play an important role in coral reef degradation. A graphic summary of the spatial configuration the sources and sinks is provided to guide the prioritization of interventions. The scale of intervention required to achieve the desired marine outcome is so large that a combined voluntary and regulatory approach is needed.
Comparing Two Applicative Criteria of the Soil Erosion Physical Model Concept
Authors: Bagarello Vincenzo , Ferro Vito , Pampalone Vincenzo 
Published: December 2017

Core Ideas
The physical model concept allows testing of the reliability of soil loss predictions.
This concept was applied by using the original and a new criterion in southern Italy.
The new criterion was generally more restrictive than the original one.
The physical model represented by a replicated plot has been suggested to be the best possible, unbiased, real world model to predict plot soil erosion. The aim of this investigation was to compare the original applicative criterion of the physical model concept proposed by Nearing with that later suggested by Bagarello et al. The comparison was performed by using three empirical soil erosion models (the Universal Soil Loss Equation [USLE], a modified USLE [USLE‐MM], and the Central and Southern Italy [CSI] model) and plot soil loss data collected at the experimental station of Sparacia, in Sicily (southern Italy). The investigation showed that (i) the new criterion was generally more restrictive, i.e., less prone to accept the similarity hypothesis between predictions and measurements, than the original one; (ii) the new criterion gave a similar number of acceptable predictions as the original one when absolute differences between measured and predicted soil losses by the replicated plot were associated with a frequency occurrence factor of 0.87; (iii) for both tested criteria, the percentage of acceptable predictions could be considered time independent, and consequently, the checked performances of the three soil loss models could be considered generally representative of their capability in predicting soil losses at the sampled site; (iv) with the exception of the calibrated USLE, the hypothesis that, according to the original criterion, an effectiveness coefficient greater and lower than 0.6 could be expected for a calibrated and uncalibrated model, respectively, was confirmed; and (v) the new criterion allowed establishment of an effectiveness coefficient of 0.12, which discriminates between uncalibrated and calibrated models.

Adhesive Drug Delivery Systems Based on Polyelectrolyte Complex Nanoparticles (PEC NP) for Bone Healing
Authors: Muller Martin , Vehlow David , Torger Bernhard , Urban Birgit , Woltmann Beatrice , Hempel Ute 
Published: December 2017

Background:
In this contribution an overview is given on own work concerning drug loaded Polyelectrolyte
Complex (PEC) Nanoparticles (NP) used to functionalize Bone Substitute Materials (BSM) for the therapy
of bone defects associated with systemic bone diseases. In this context, drug loaded PEC NP have certain advantages,
which are exemplarily summarized herein.

Methods:
Concerning preparative methods PEC NP were fabricated by controlled mixing of polycation and polyanion
solutions and integration of charged drugs during and after mixing. Control was taken on the stoichiometric
ratio related to cationic and anionic repeating units, which was chosen close to zero for the final applied PEC NP.
Concerning analytical methods a couple of physical-chemical methods were applied like colloid titration, Dynamic
Light Scattering (DLS), Scanning Force Microscopy (SFM), Fourier Transform infrared (FTIR) spectroscopy,
Ultraviolet-Visible (UV-VIS) and Circular Dichroism (CD) spectroscopy to characterize colloid stability,
adhesiveness, drug loading and release of PEC NP. Moreover, standard biochemical and microbiological assays
were applied.

Conclusion:
Drug loaded PEC NP consist of oppositely charged biorelated Polyelectrolytes (PEL) like ionic
polysaccharides or ionic polypeptides and also synthetic PEL, which are mixed and processed in aqueous media.
At first, freshly prepared drug/PEC NP exhibit time dependent colloidal stability in the range of weeks and
months, which enables and simplifies storage, transport and application in the medical field. Secondly, after
deposition and drying of drug/PEC NP a local wet adhesive PEC matrix at the BSM remains in contact to relevant
aqueous media (e.g. buffer, cell culture medium), which minimizes asepsis, systemic toxicity, immune or inflammatory
reaction. Thirdly, cell compatible PEC NP coatings were identified, which showed only minimal
effects on various relevant bone related cells due to biorelateness, complexation, local confinement and low surface
area. Fourthly, PEC NP elute drugs for bone healing like bisphosphonates, antibiotics and growth factors
(e.g. bone morphogenetic proteins) in delayed and sustained manner. Moreover, the onset of elution could be
triggered by thermoresponsive PEL via temperature increase giving clinicians a tool into hand allowing spatiotemporal
drug release on demand. Finally, drug/PEC NP could be integrated into commercial or still developed
allotropic stabilizing or defect filling BSM systems.
Substrates for Paraoxonase
Authors: Mu Xiaojing , Yi Xiaoqi , Xiao Shangyou , Wang Chengshan , Chen Gang , Li Yan 
Published: December 2017

Background:
Paraoxonase (PON) is a family of calcium-dependent hydrolases, which is related to
many diseases. Elucidation of PON physiological roles, active center and all applications in medical fields are
dependent on its substrates.

Objective:
The reports about PON substrates scattered in a long span of period are collected to afford clue for
drug design, diagnosis of PON status and other academic purposes.

Method:
PON substrates from 133 references are classified and compared. Structurally, PON substrates are generally
classified as organic phosphorous esters, lactones and arylesters. Some phosphoramidates, organophosphorous
obidoximes, aryl carboxylic acid amides and special fatty alcohol esters as PON substrates are also included.

Results:
The electron nature, steric hindrance and hydrophilicity of substrate substituents affecting the PON catalytic
ability, binding ability and specificities are discussed. Drugs, prodrugs and naturally endogenous molecules
in life processes activated or inactivate by PON are reviewed. Interestingly, some organophosphate and lactone
substrates are preferably hydrolyzed by one of the PON1R192Q allozymes, and such a substrate is generally essential
for differentiating the three PON1192R phenotypes by using a dual-substrate method. Intricately, some chiral
substrates are hydrolyzed by PON stereoselectively.

Conclusion:
As more substrates are synthesized and characterized, more facts about PON structure and catalytic
properties (including PON active center and catalytic mechanism) will be revealed, and therefore the use of PON
as a drug target or as an accurate disease marker will be achieved.
Genetic Variability of SRC Family Kinases and Its Association with Platelet Hyperreactivity and Clinical Outcomes: A Systematic Review
Authors: Milanowski Lukasz , Rasul Fazila , Gajda Sylwia Natalia , Eyileten Ceren , Siller-Matula Jolanta , Postula Marek 
Published: December 2017

Background:
Platelet hyperactivity has been implicated in many cardiovascular (CV) events such as
ischemic stroke, myocardial infarction and CV death. Genetic variability of platelet receptors has been shown to
impact Src family kinases (SFKs) activation and in turn influence platelet activation. SFKs are important signal
transmitters in platelets, interacting with several receptors as GPIIB/IIIa, GPIb, PEAR 1, GPIa, GPVI, PECAM
and CD148.

Methods:
In this review, we focused on genetic variants of platelet receptors whose signals are transmitted
mainly by SFKs and may be associated with clinical manifestations of platelet hyperactivation like MI or IS.

Results:
The genetic variants of platelet receptors, the signals of which are transmitted by SFKs, and the associated
clinical manifestations in platelet hyperactivation, have been examined. The most extensively studied receptors
were glycoprotein polymorphisms. The greatest numbers of genetic variants were analyzed in GPIb.
GPIIb/IIIa receptor polymorphisms were also well analyzed and many studies highlighted their associations with
ischemic stroke (IS) and myocardial infarction (MI). However, there are a number of conflicting studies finding
that GPIIb/IIIa receptor polymorphisms may not influence platelet hyperactivity. Moreover, variability within
some other receptors like GPVI, PECAM, PEAR1, and CD148 was analyzed only in single studies.

Conclusions:
Src family kinases are one of the most important signal transmitters in platelets. Some receptors
have well documented interactions with SFKs, while other have not been examined in humans or data about its
association originated from single studies. Further studies are necessary to confirm the findings and reduce falsepositive
associations.
