Effects of nifedipine on fetal cardiac function in preterm labor
Authors: Yilmaz Osman , Göncü Ayhan Şule
Published: July 2020

Objectives

To evaluate the effects of nifedipine treatment on fetal hemodynamics and cardiac function during preterm labor. This prospective study assessed several quantitative parameters of fetal cardiac circulation and function, and found no significant changes at 48 h after nifedipine treatment. These findings suggest that tocolytic nifedipine may be safe for fetuses. It supports clinicians to use nifedipine treatment for tocolysis without any cardiac effect on the fetus.

Methods

A prospective cohort study was conducted at a tertiary hospital between January 2016 and October 2017. A total of 45 pregnant women who required nifedipine for preterm labor were included in this study. Fetal Doppler ultrasound was performed and fetal systolic and diastolic function was measured prior to, and 48 h after, the first nifedipine treatment. Conventional Doppler parameters were used to evaluate fetal heart function and hemodynamic changes. Tricuspid annular plane systolic excursion, mitral annular plane systolic excursion and the sphericity index were also evaluated to assess changes in fetal cardiac morphology.

Results

No significant changes in fetal Doppler parameters were observed following nifedipine tocolysis. There was no significant difference in the fetal cardiac function parameters of both ventricles before vs. after nifedipine treatment. Tricuspid annular plane systolic excursion, mitral annular plane systolic excursion, and sphericity index values were unchanged following nifedipine treatment.

Conclusions

Oral administration of nifedipine did not to alter fetal cardiac function or morphology. Fetal cardiac parameters and various Doppler indices were unchanged following nifedipine treatment. Maternal nifedipine treatment does not appear to have any significant effect on fetal cardiac function.

Authors: Han Yu , Li Mengnan , Ma Huijing , Yang Hailan
Published: July 2020

Cervical insufficiency (CI) is a mainly disease leading to recurrent abortions and preterm birth which may present in about 1% of obstetric populations. Recurrent pregnancy losses caused by CI incur serious economic burdens on society as well as huge psychological burdens to family members. However, many patients even clinicians in some areas of the world still remain confused about this disease. At the same time, the etiology of CI is still uncertain and it is still a controversial disease in diagnosis and treatment. This article summarizes the potential risk factors associated with CI, which could be worthy of attention and helpful for future research. It also reviews the methods for diagnosis and treatment of CI to better understand this noteworthy disease, as well as presents the related consensus and controversies according to the newly updated guidelines, which has practical significance for conducting more in-depth investigations in the future.
Boundary Morphology for Hierarchical Simplification of Archaeological Fragments
Authors: ElNaghy Hanan , Dorst Leo
Published: July 2020

When fitting archaeological artifacts, one would like to have a representation that simplifies fragments while preserving their complementarity. In this paper, we propose to employ the scale-spaces of mathematical morphology to hierarchically simplify potentially fitting fracture surfaces. We study the masking effect when morphological operations are applied to selected subsets of objects. Since fitting locally depends on the complementarity of fractures only, we introduce‘Boundary Morphology’on surfaces rather than volumes. Moreover, demonstrating the Lipschitz nature of the terracotta fractures informs our novel extrusion method to compute both closing and opening operations simultaneously. We also show that in this proposed representation the effects of abrasion and uncertainty are naturally bounded, justifying the morphological approach. This work is an extension of our contribution earlier published in the proceedings of ISMM2019 [10].
Controlling the plasmon resonance via epsilon-near-zero multilayer metamaterials
Authors: Habib Mohsin , Briukhanova Daria , Das Nekhel , Yildiz Bilge Can , Caglayan Humeyra
Published: July 2020

Localized plasmon resonance of a metal nanoantenna is determined by its size, shape and environment. Here, we diminish the size dependence by using multilayer metamaterials as epsilon-near-zero (ENZ) substrates. By means of the vanishing index of the substrate, we show that the spectral position of the plasmonic resonance becomes less sensitive to the characteristics of the plasmonic nanostructure and is controlled mostly by the substrate, and hence, it is pinned at a fixed narrow spectral range near the ENZ wavelength. Moreover, this plasmon wavelength can be adjusted by tuning the ENZ region of the substrate, for the same size nanodisk (ND) array. We also show that the difference in the phase of the scattered field by different size NDs at a certain distance is reduced when the substrate is changed to ENZ metamaterial. This provides effective control of the phase contribution of each nanostructure. Our results could be utilized to manipulate the resonance for advanced metasurfaces and plasmonic applications, especially when precise control of the plasmon resonance is required in flat optics designs. In addition, the pinning wavelength can be tuned optically, electrically and thermally by introducing active layers inside the hyperbolic metamaterial.

Protest and the City: On Object, Affect and Vulnerability
Authors: Singh Niharika
Published: July 2020

A lathi has a flesh of its own. Gandhi carried one, the police carries its own. Fashioned of wood thinned out and stemmed long, lathis being sold in shops are as unnerving as when clutched in hands, building authority. In one, it refuses to be simply ornamental, in the other, it marks bodies with legality. Authority emanates from this marking, the blood that spills and the deaths of which accountability is in its invisibility of documentation. Lathis are charged on the suspecting/unsuspecting who force an appearance in spaces distanced from actual belonging. In this article, there is a narrative of such a breakdown of the conflict itself, the space and the appearances. Reading through affect is a lot about undoing; grand concepts, strict functioning, identities addressed. Affect also has a lot to do with attachments. And attachments flow in and out of a network wherever bodies gather, in assemblies, demonstrations, in strikes and in riots. In these attachments, decisions are felt which later empiricist read as fixity of ideas and ideologies, only later, but affect is in the now.
Theories for triboelectric nanogenerators: A comprehensive review
Authors: Zhang He , Yao Linjie , Quan Liwei , Zheng Xianglong
Published: July 2020

Triboelectric nanogenerators (TENGs) have attracted much attention as energy harvesting and sensor devices. Compared with experimental means, theoretical analysis is of low cost and time-saving for behavior prediction and structural optimization and is more powerful for understanding the working mechanism of TENGs. In this article, the theoretical system for performance simulation of TENGs has been reviewed systematically. The parallel-plate capacitor model, the distance-dependent electric field (DDEF) model, figures of merit (FOMs), and multi-parameter analysis are introduced. The parallel-plate capacitor model is the most fundamental model of TENGs, which is used to simulate the output of TENGs with planar configurations. For non-planar TENGs, the DDEF model is proposed, according to which the electric field is assumed to be distance-dependent rather than being uniform throughout the space. Further, to realize the standardization of TENGs, a series of FOMs are proposed as the standardized evaluation tools for TENGs’ output performance, which are used to reflect the influence of device parameters on the output from different aspects. Lastly, the multi-parameter analysis is introduced to consider the impact of multiple parameters on the output of TENGs simultaneously. These theories constitute the theoretical simulation system of TENGs, which could be used to guide the experimental work on TENGs and boost device optimization in commercial manufacturing.
Development and preliminary validation of the Chronic Pain Acceptance Questionnaire for Clinicians
Authors: Rabey Martin , Catley Mark , Vowles Kevin , Appleton Damien , Bennett Richard , McAuley James
Published: July 2020

Background and Aims

Higher chronic pain acceptance is associated with lower pain and disability. Clinician beliefs are associated with patients’ beliefs. This study therefore aimed to develop the Chronic Pain Acceptance Questionnaire for Clinicians (CPAQ-C) to measure clinicians’ beliefs regarding the importance of levels of acceptance in patients with chronic pain, and to examine the questionnaire’s psychometric properties.

Methods

Phase one: the CPAQ-C was adapted from the Chronic Pain Acceptance Questionnaire. Data on 162 completed questionnaires were analysed using Rasch analysis. Phase Two: the cohort completed the Healthcare Providers Pain and Impairment Relationship Scale, and the association (Pearson’s correlation co-efficient) between these questionnaires examined to assist CPAQ-C validation. Twenty-four participants completed the CPAQ-C one-week later. Test re-test reliability was examined using intraclass correlation co-efficient (2,1) and standard error of measurement. Phase Three: to examine responsiveness 17 clinicians attending a workshop on Acceptance and Commitment Therapy completed the CPAQ-C before and immediately after the workshop, and six-months later. The Skillings Mack test was used to determine whether CPAQ-C scores differed across different timepoints.

Results

Rasch analysis supported two subscales: activity engagement and pain willingness. Five poorly functioning items were excluded. There was good correlation between the CPAQ-C and Healthcare Providers Pain and Impairment Relationship Scale (-.54). The CPAQ-C demonstrated good reliability (ICC (2,1): .81; standard error of measurement: 4.76). There was significant improvement in CPAQ-C scores following the workshop (p=<.001).

Conclusions

The CPAQ-C appears a valid, reliable and responsive measure of clinicians’ beliefs regarding the importance of levels of acceptance in patients with chronic pain.

Implications

Where the CPAQ-C reveals that clinicians have low perceived levels of importance regarding acceptance in patients with chronic pain those clinicians may benefit from specific education, however, this requires further examination.
A novel clinical applicable bed-side tool for assessing conditioning pain modulation: proof-of-concept
Authors: Arendt-Nielsen Lars , Larsen Jesper Bie , Rasmussen Stine , Krogh Malene , Borg Laura , Madeleine Pascal
Published: July 2020

Background and aims

In recent years, focus on assessing descending pain modulation or conditioning pain modulation (CPM) has emerged in patients with chronic pain. This requires reliable and simple to use bed-side tools to be applied in the clinic. The aim of the present pilot study was to develop and provide proof-of-concept of a simple clinically applicable bed-side tool for assessing CPM.

Methods

A group of 26 healthy volunteers participated in the experiment. Pressure pain thresholds (PPT) were assessed as test stimuli from the lower leg before, during and 5 min after delivering the conditioning tonic painful pressure stimulation. The tonic stimulus was delivered for 2 min by a custom-made spring-loaded finger pressure device applying a fixed pressure (2.2 kg) to the index finger nail. The pain intensity provoked by the tonic stimulus was continuously recorded on a 0–10 cm Visual Analog Scale (VAS).

Results

The median tonic pain stimulus intensity was 6.7 cm (interquartile range: 4.6–8.4 cm) on the 10 cm VAS. The mean PPT increased significantly (P = 0.034) by 55 ± 126 kPa from 518 ± 173 kPa before to 573 ± 228 kPa during conditioning stimulation. When analyzing the individual CPM responses (increases in PPT), a distribution of positive and negative CPM responders was observed with 69% of the individuals classified as positive CPM responders (increased PPTs = anti-nociceptive) and the rest as negative CPM responders (no or decreased PPTs = Pro-nociceptive). This particular responder distribution explains the large variation in the averaged CPM responses observed in many CPM studies. The strongest positive CPM response was an increase of 418 kPa and the strongest negative CPM response was a decrease of 140 kPa.

Conclusions

The present newly developed conditioning pain stimulator provides a simple, applicable tool for routine CPM assessment in clinical practice. Further, reporting averaged CPM effects should be replaced by categorizing volunteers/patients into anti-nociceptive and pro-nociceptive CPM groups.

Implications

The finger pressure device provided moderate-to-high pain intensities and was useful for inducing conditioning stimuli. Therefore, the finger pressure device could be a useful bed-side method for measuring CPM in clinical settings with limited time available. Future bed-side studies involving patient populations are warranted to determine the usefulness of the method.
When is discretionary fiscal policy effective?
Authors: Fazzari Steven M. , Morley James , Panovska Irina
Published: July 2020

We investigate the effects of discretionary changes in government spending and taxes using a medium-scale nonlinear vector autoregressive model with policy shocks identified via sign restrictions. Tax cuts and spending increases have larger stimulative effects when there is excess slack in the economy, while they are much less effective, especially in the case of government spending increases, when the economy is close to potential. We find that contractionary shocks have larger effects than expansionary shocks across the business cycle, but this is much more pronounced during deep recessions and sluggish recoveries than in robust expansions. Notably, tax increases are highly contractionary and largely self-defeating in reducing the debt-to-GDP ratio when the economy is in a deep recession. The effectiveness of discretionary government spending, including its state dependence, appears to be almost entirely due to the response of consumption. The responses of both consumption and investment to discretionary tax changes are state dependent, but investment plays the larger quantitative role.
Some integral inequalities for operator monotonic functions on Hilbert spaces

Let f be an operator monotonic function on I and A, B∈I (H), the class of all selfadjoint operators with spectra in I. Assume that p : [0.1], →ℝ is non-decreasing on [0, 1]. In this paper we obtained, among others, that for A ≤ B and f an operator monotonic function on I,

\matrix{0 \hfill & { \le \int\limits_0^1 {p\left( t \right)f\left( {\left( {1 - t} \right)A + tB} \right)dt - \int\limits_0^1 {p\left( t \right)dt\int\limits_0^1 {f\left( {\left( {1 - t} \right)A + tB} \right)dt} } } } \hfill \cr {} \hfill & { \le {1 \over 4}\left[ {p\left( 1 \right) - p\left( 0 \right)} \right]\left[ {f\left( B \right) - f\left( A \right)} \right]} \hfill \cr }

in the operator order.

Several other similar inequalities for either p or f is differentiable, are also provided. Applications for power function and logarithm are given as well.
In vitro and in silico studies on AChE inhibitory effects of a series of donepezil-like arylidene indanones
Authors: Sever Belgin , Altıntop Mehlika Dilek , Temel Halide Edip
Published: July 2020

Objective

Donepezil is the most potent acetylcholinesterase (AChE) inhibitor currently available on the market for the management of Alzheimer’s disease. In this study, it was aimed to identify potent donepezil analogues.

Materials and methods

The effects of arylidene indanones (1–10) on AChE inhibition were examined using modified Ellman’s assay. Compound 4, the most potent arylidene indanone in this series, was subjected to molecular docking to anticipate its binding mode in the AChE site (PDB code: 4EY7). The pharmacokinetic profiles of all derivatives were also predicted.

Results

Compound 4 was found as the most potent AChE inhibitor with an IC50 value of 5.93 ± 0.29 μg/mL. According to molecular docking studies, compound 4 presented favorable interactions such as π–π interactions with Trp286 and Tyr337. In silico studies revealed that the compound did not violate Lipinski’s rule of five and Jorgensen’s rule of three, making it a potential orally bioavailable agent.

Conclusion

Compound 4 is a feasible candidate for further experiments related to AChE inhibition.
Augschburgerischauf Facebook: Enregisterment und Mediatisierung eines urbanen Dialekts
Authors: Niehaus Konstantin
Published: July 2020

This article examines language and local identity in an urban space analysing the enregisterment of a local variety at one of the most relevant dialect borders in Germany: the Bavarian city of Augsburg which is in close proximity to both Upper Bavaria and Bavaria’s capital Munich. The local dialect of Augsburg mixes Swabian-Alemannic and Bavarian features and it is because of this mix that Swabians, the group to which the Augsburgians are generally deemed to belong to, are often regarded not to be ‘proper’ Bavarian speakers.Augschburgerischhas become a stylized register with authenticated sociolinguistic features and can thus be employed to construct local identity and index a stereotyped group of speakers, e. g. that local dialect speakers are down-to-earth but grumpy and close-lipped towards strangers. This study examines Augsburgian on social media by qualitatively analysing posts from a local Facebook group. In these posts, authentification practices are used to resolve the ambiguous nature of what it means to be ‘Bavarian’ and the intricacies imposed on the speakers by the border situation while also highlighting the users’ creativity via ironic role alignments.
Kommunikative Beteiligung von Partnern in der Schwangerenberatung
Authors: Völker Ina
Published: July 2020

The interaction between midwifes or other medical professionals and pregnant women in the last trimester of pregnancy plays an important role during antenatal care and birth. The partners of the pregnant women are often present for these conversations and can affect the interaction with their contributions, e. g. their input to the birth plan and their experiences during pregnancy. In this interactional work, triadic interactions during antenatal care consultations were analysed. Using examples from a corpus of 37 primary consultations between midwifes, pregnant women and doctors in an obstetric ward, it is shown that partners can affect the information exchange during these interactions. With their utterances, partners can provide various information, such as facts about previous deliveries, information about the pregnant woman, own pregnancy experiences, information about past abortions and miscarriages as well as information about congenital diseases. In doing so, they enriched the conversation and provided emotional support for the pregnant woman. Only very few partners acted in the role of ‘critic’ or ‘opponent’ and controlled the informational exchange between midwife and pregnant woman or focused solely on themselves during these interactions.
Repetition Increases Perceived Truth Even for Known Falsehoods
Authors: Fazio Lisa K.
Published: July 2020

Repetition increases belief in false statements. This illusory truth effect occurs with many different types of statements (e.g., trivia facts, news headlines, advertisements), and even occurs when the false statement contradicts participants’ prior knowledge. However, existing studies of the effect of prior knowledge on the illusory truth effect share a common flaw; they measure participants’ knowledge after the experimental manipulation and thus conditionalize responses on posttreatment variables. In the current study, we measure prior knowledge prior to the experimental manipulation and thus provide a cleaner measurement of the causal effect of repetition on belief. We again find that prior knowledge does not protect against the illusory truth effect. Repeated false statements were given higher truth ratings than novel statements, even when they contradicted participants’ prior knowledge.
Assembling the Chimeric Sex Offender
Authors: Spencer Dale C. , Ricciardelli Rosemary
Published: July 2020

Across societies labels rarely are met with the degree of contempt and hatred that has become inherent in the label of “sex offender,” applied to those who offend the morals, ethics, and values of citizens because of the actions (or sexual affinities) in which they are believed to have engaged. In the current article, we examine the diverse ways the sex offender is assembled, drawing on assemblage theory. We examine the signifiers attached to bodies suspected, accused, and convicted of sex offenses and the material connections that come together as part of the chimeric sex offender assemblage. We demonstrate that the arrangement of signifiers and materiality reflects the complex landscape that is expressed in the image of the monstrous sex offender. Our contribution to the literature on sex offenders lies in demonstrating the chimeric nature of the sex offender.
Pleural effusion as a novel prognostic factor in metastatic thyroid carcinoma
Authors: Broome David T , Gadre Gauri B , Fayazzadeh Ehsan , Bena James F , Nasr Christian
Published: July 2020

Objective:

To identify novel prognostic risk factors and compare them with other known prognostic risk factors in follicular-cell-derived thyroid carcinoma (FDTC) with distant metastases.

Methods:

A retrospective review was conducted of adult patients with metastatic FDTC seen at a tertiary care center between January 1990 and December 2010. A 15-year Kaplan–Meier survival estimate was created for overall survival (OS) and cancer-specific survival (CSS). Hazard ratios (HR) and P values from Cox proportional hazard models were used with a 95% CI.

Results:

There were 143 patients (60.1% male, 39.9% female), of whom 104 (72.7%) patients had papillary, 30 (21.0%) had follicular, 5 (3.5%) had poorly differentiated, and 4 (2.8%) had Hürthle cell cancers. Median length of follow-up was 80.0 months (range 1.0–564.0). The 15-year mortality rate was 32.2% and cancer-specific mortality was 25.2%, with OS and CSS having the same risk factors. Lung was the most common site of metastases in 53 patients (37.1%), and patients with pleural effusions had significantly lower CSS (HR = 5.21, CI = 1.79–15.12). Additional risk factors for a decreased CSS included: older age upon diagnosis (>45 years, HR = 4.15, CI = 1.43–12.02), multiple metastatic locations (HR = 3.75, CI = 1.32–10.67), and incomplete/unknown tumor resection (HR = 2.35, CI = 1.18–4.67).

Conclusion:

This study is the first to demonstrate that pleural effusion is a poor prognostic sign in patients with FDTC with distant metastases and compare this risk with other accepted prognostic variables.

Evaluating the Effect of Design and Length of Implants on Primary Stability Using Resonance Frequency Analysis: An In Vitro Study
Authors: USTAOĞLU Gülbahar , PAKSOY Tuğçe , GÜMÜŞ Kerem
Published: July 2020

Background:Primary stability (PS) is dependent on the length and diameter of the implant, micro-morphology of the implant surface, implant design, surgical procedure, bone quantity and quality.The aim of this study was to compare short and standart dental implants according to primary stability in bone type IV using Resonance frequency analysis (RFA) test equipment.Methods: Seventy two dental implants; sandblasting with large grit particles and acid etching (SLA) surface (Dentium®,SimpleLine II, Seoul, Korea), SLActive surface- (Straumann Roxolid®, Basel, Switzerland), Resorbable blast media (RBM) surface- (Implance®,Trabzon, TURKEY) with short (4-and 6-mm length) and standart dental implants (10-mm length) were placed in bovine cow ribs with bone quality similar to a type IV human bone.RFA was performed to evaluate the primary stability. The parameters of three groups were compared with the Mann–Whitney U test. Results:Implant stability quotient (ISQ)measurements of 4-mm and 6-mm length implants were similar however, 10-mm-length implants showed statistically difference inter-groups. SLActive surface in 10-mm-length implant group showed highest ISQ value (p < 0.005). When primary stability was compared in intra groups, SLA surface and RBM surface implants showed no significant difference, but 10-mm-length of SLActive surface implant showed higher ISQ value than 4-and 6-mm length (p< 0.005).Conclusion: The length and diameter of the implants might be more effective in primary stability compared to surface design and surface properties in short implants and SLActive surface implants may show better primary stabiliy in standard implants.
Maksiller Daimi Kesici Dişte İzlenen Çift Diş Oluşumunun Tedavisi: Olgu Raporu
Authors: ELMAS Seda , ODABAŞ Mesut
Published: July 2020

Füzyon ve geminasyon, özellikle süpernumere diş veya
hipodontiyle birlikte görüldüğü durumlarda klinik olarak ayırıcı tanı koymak
zor olmaktadır. Bu nedenle çoğu araştırmacı bu dişler için “çift diş” terimini
kullanmayı tercih etmektedir. Eğer bu dişler komşu iki diş germinin birleşmesi
sonucu oluşuyorsa füzyon; tek diş germinin bölünme girişimi sonucu oluşuyorsa
geminasyon olarak tanımlanmaktadır. Bu olgu sunumunda daimi üst sol santral
dişi etkileyen çift diş olgusunun tedavisi anlatılmaktadır. Yapılan klinik ve
radyografik muayeneler sonucunda, bu dişin üst sol santral kesici ile
süpernumere dişin füzyonundan oluştuğu belirlenmiştir. Çift diş, komşu santral
dişin kron boyutunda olacak şekilde ikiye ayrılarak süpernumere diş, ilgili
kökle birlikte çekilmiştir. Bir yıllık takip sonunda sol santral kesici dişin
vitalitesinin devam ettiği belirlenmiştir. Bu olgu, çift dişin ayrılmasında
doğru teşhisin önemli olduğunu ve konik ışınlı bilgisayarlı tomografi (KIBT)
tabanlı verilerin komplike olan tedavi planlanmasında oldukça yararlı olduğunu
göstermektedir.
Radyoterapiyi takiben kritik boyutta oluşturulan kemik defektlerinde antibiyotiklerin etkinliğinin deneysel olarak incelenmesi
Authors: GÜNAY Özgün , DOĞANAY Özge , TOK Olgu Enis , ALKAN Alper
Published: July 2020

Amaç: Çenelerin osteoradyonekrozu (ORN), baş ve boyun kanserlerinde radyasyon tedavisinin bir komplikasyonu olarak karşımıza çıkmaktadır. Tanımı ve sınıflandırması yıllar içinde değişiklik göstermiş, patofizyolojisine dair teorileri geliştirilmiş ve buna bağlı olarak farklı tedavi prensipleri denenmiştir. Çalışmadaki amacımız, radyoterapiyi takiben alt çene kemiğinde cerrahi olarak oluşturulan kritik boyuttaki defektlerde klindamisin, metronidazol, rifamisin ve doksisiklin grubu antibiyotiklerin kemik iyileşmesi üzerindeki etkilerini incelemekti.
Gereç ve Yöntem: Anti-enflamatuar etkinliğin kemik iyileşmesi üzerindeki etkilerini değerlendirmek için, 50 adet Wistar cinsi albino türü sıçanlar kullanılmıştır. Tüm gruplara genel anestezi altında 30 Gy dozda radyoterapi uygulandıktan 8 hafta sonra sıçanların sağ mandibulasında 5 mm çapında bikortikal hazırlanan kemik defektlerine deney gruplarında ksenogreft ile karıştırılan antibiyotikler, kontrol gruplarında ise sadece ksenogreft partikülleri uygulanarak cerrahi saha iyileşmeye bırakılmıştır. Sakrifikasyon sonrasında elde edilen örneklerde enflamasyon, nekroz, fibrozis, yeni kemik yapım alanı, kalsifiye olmuş kemik alanı ve kapiller sayısı histopatolojik ve histomorfometrik olarak değerlendirildi.
Bulgular: İncelenen kesitlerde nekroz, enfeksiyon ya da fibrozis bulgusuna rastlanmamıştır. Kontrol grubu ile yapılan karşılaştırmalarda metronidazol ve klindamisin gruplarında yeni kemik yapım alanlarının anlamlı derecede yüksek olduğu görülmüştür (p<0.01, p<0.01). Kalsifiye kemik trabekül alanları incelendiğinde kontrol grubu ile klindamisin grubu arasında istatistiksel olarak ileri derecede anlamlı fark tespit edilmiştir (p<0.01). Klindamisin ile diğer gruplar karşılaştırıldığında ise aradaki fark anlamlı (p<0.05) bulunmuştur. Kontrol grubu ile yapılan karşılaştırmalarda kapiller sayısı metronidazol grubunda anlamlı (p<0.05), klindamisin grubunda (p<0.01) ise ileri derecede anlamlı olarak farklı bulunmuştur.
Sonuç: Antibiyotik uygulanan gruplarda iltihabi alanların sayısında azalma, yeni kemik yapım alanlarında ve damarlanmada artış gözlenmiştir. Çalışmada kullandığımız antibiyotiklerin antibakteriyel aktiviteden bağımsız olarak anti- enflamatuar etkinliklerinin olabileceği düşünülmektedir.

Bioética e Direito: uma análise dos princípios bioéticos aplicados ao Biodireito
Authors: Velasquez Tomlyta Luz , De Souza Paulo Vinicius Sporleder
Published: July 2020

O presente artigo propõe analisar os princípios bioéticos e a possibilidade de sua aplicação no âmbito do Biodireito. Mais especificamente, após um breve panorama da teoria dos princípios na seara jurídica, abarcando as principais evoluções doutrinárias, foca-se nos princípios da Bioética estruturados pelo Principialismo, que apresenta os princípios básicos para o agir humano frente a uma moralidade comum, abordando-se tanto os seus fundamentos que consagraram o uso dos princípios nos dilemas bioéticos, quanto as críticas sofridas que resultaram em nova proposta de estrutura principiológica. Finalmente, se discute o contexto dessa nova proposta de princípios bioéticos fundada na Europa, que fortalece a preocupação com a coexistência entre o ser humano e os demais seres vivos que colaboram com o equilíbrio da vida, bem como a sua possível aplicação ao Biodireito, como salvaguarda da dignidade dos seres humanos nas questões éticas e jurídicas criadas pelos avanços biotecnológicos.
O que há de realmente atemorizador nos cenários tipo-Gattaca?
Authors: Azevedo Marco Antonio , Rolim Marcos
Published: July 2020

No filme Gattaca, imagina-se um futuro já nada distante em que os casais poderão consultar um especialista em fertilização artificial e escolher as características de seu futuro filho. Eles podem selecionar embriões fertilizados em laboratório, podendo também alterar seus traços genéticos, eliminando genes capazes de expressar doenças ou mesmo características físicas indesejáveis. Técnicas recentes, como a edição genética por Prime Editing ou por meio da CRISPR-Cas9, logo permitirão terapias gênicas em embriões fertilizados in vitro antes de sua implantação uterina. Neste artigo, pretendemos avaliar essas possibilidades, revisando criticamente alguns argumentos conhecidos contra o uso indiscriminado de tais técnicas (como o argumento da ladeira escorregadia, e os argumentos de Jurgen Habermas e Michael Sandel). Ao final, em defesa de que objeções de princípio a práticas eugênicas devem estar assentadas na proteção e promoção dos direitos humanos, pretendemos avaliar quais limites poderiam publicamente justificar a permissão ou proibição do uso privado de tais técnicas.

El desierto era parecido a un paraíso. Aventuras posthumanas en una novela de G. Cabezón Cámara
Authors: Fleisner Paula
Published: July 2020

Este artículo parte de la perspectiva del materialismo posthumano, una línea de investigación que asume el presente como un contexto postantropocéntrico y postnatural en el que se ha vuelto indispensable volver a considerar las diversas lógicas de existencia que pueblan la Tierra. Es decir, se trata de pensar el espacio post/inhumano que se abre con la interacción, la hibridación y la co-emergencia de todo lo existente en la que los actores humanos están presentes pero no ya en el centro de la acción, sino en una mezcla de agencialidades diversas. En esta oportunidad se presentará una lectura de Las aventuras de la China Iron, de Gabriela Cabezón Cámara (2017), desde una estética materialista posthumana. Por un lado, en la medida en que la narradora es un animal humano, la novela será entendida como una descripción horizontal y no jerárquica del lugar de la “humanidad” en el planeta; y, por el otro, como la exploración de las mutuamente contaminadas potencias de actuar, pensar y sentir de lo existente en general: lo animal, lo vegetal y lo mineral no ya taxonomizados en reinos sino mezclados en el “compost” sin alambrado, ingobernable y fértil que podría ser el “desierto” argentino. De esta forma, en tanto que reescritura del Martín Fierro, texto considerado fundacional de la identidad nacional argentina, la novela de Cabezón Cámara podría ser la fabulación de una “matria” queer y holoéntica que alberga criaturas de múltiples especies y reinos.
STUDIUM PRZYPADKU POLSKIEGO UCZNIA Z DYSLEKSJA UCZĄCEGO SIĘ JĘZYKA ANGIELSKIEGO JAKO JĘZYKA OBCEGO METODĄ MULTISENSORYCZNĄ ORAZ WPŁYW TAKIEGO NAUCZANIA NA SKUTECZNOŚC WŁASNĄ UCZNIA
Authors: Gosiewska-Turek Bogusława
Published: July 2020

Cel: Celem badania jest wykazanie iż uczniowie z dysleksją podczas nauki języka obcego wymagają wyjątkowego traktowania, innego od tego jakie jest oferowane uczniom bez szczególnych potrzeb edukacyjnych. To szczególne działanie dotyczy zarówno zindywidualizowanego podejścia do ucznia jak i zastosowania szczególnych metod nauczania języka obcego ułatwiających naukę uczniom z dysleksją

Metody: Autorka przeprowadziła badanie opisowe przypadku, w którym przez okres 6 tygodniu zastosowała 6 indywidualnych sesji, podczas których nauczała języka angielskiego dwunastoletniego chłopca z dysleksją. Ponadto w celu uzyskania triangulacji danych przed rozpoczęciem oraz po zakończeniu badania uczeń wypełnił kwestionariusz na skuteczność własną

Wyniki: Rezultaty przeprowadzonego badania pokazują, iż indywidualne sesje z uczniem z dysleksją poprawiły znacznie jego kompetencje językowe oraz podniosły skuteczność własną, która jest z kolei warunkiem efektywnego uczenia się

Wnioski: Poniższe badanie wskazuje na to, że w szkołach powinno być zapewnione dostosowanie metod nauczania do pracy z uczniem z dysleksją. W celu zapewnienia efektywnego nauczania tych uczniów ich nauka języka obcego powinna być zindywidualizowana. To nie tylko pozwoli na bardziej efektywne przyswajanie materiału, ale również na podniesienie motywacji u dyslektyków
Medialny wizerunek osoby z autyzmem kreowany w filmach
Authors: Dubiel Olimpia
Published: July 2020

Cel badań. Celem badań było opisanie kreowanego we współczesnych filmach wizerunku osób z zaburzeniami ze spektrum autyzmu, a także określenie obszaru filmowej stygmatyzacji bohaterów z autyzmem oraz ich kulturowej i społecznej dyslokacji.

Metoda badań. Badaniom poddane zostały cztery dzieła: film dokumentalny pt. Komunia (Zamecka, 2008), dramat obyczajowy pt. Czarny balonik (Down, 2008), film biograficzny pt. Temple Grandin (Jackson, 2010) oraz komedia pt. W kosmosie nie ma uczuć (Öhman, 2010). Przy doborze utworów uwzględniono odmienność gatunkową, zróżnicowanie wiekowe bohaterówz autyzmem i poziom ich psychospołecznego funkcjonowania, a także kraj produkcji filmu.W celu realizacji badań zastosowano metodę jakościowej analizy treści.

Wyniki badań. Analiza treści filmów dowiodła, że kreują one wizerunek osób z autyzmem uwypuklający ich anormatywność – intensyfikują zarówno brak cech rozwojowo normatywnych, jak również nadzwyczajne zdolności i umiejętności tych osób. W zakresie samorealizacji społeczno-kulturowej bohaterzy podejmują różnorodne aktywności, które w konfrontacjiz neurotypowym otoczeniem eksponują deficyty poznawcze i społeczne, jak również szczególny poziom umiejętności matematycznych i konstrukcyjnych. Ekspozycja niedoborów i nadmiarów behawioralnych i społecznych ukazuje pejoratywny obraz bohaterów z zaburzeniami ze spektrum autyzmu.

Wnioski. Filmy poddane analizie treści kreują wizerunek osób z autyzmem eksponujący ich atypowość, a tym samym stygmatyzujący, przedstawiając je jako osoby poszkodowane, które wymagają stałej opieki lub osoby genialne bądź dziwaczne. Specyfika funkcjonowania filmowych bohaterów stanowi problem dla społeczności, w której żyją – osoby neurotypowe wykazują dezaprobatę i brak zrozumienia wobec zachowania wynikającego z zaburzeń ze spektrum autyzmu.
WPŁYW POZYTYWNYCH I NEGATYWNYCH EMOCJI NA DYSTANS INTERPERSONALNY, OCENĘ ORAZ POSTAWY
Authors: Urbańska Marta , Wróbel Michalina
Published: July 2020

Emocje są związane z wieloma obszarami ludzkiego życia. Wpływają na odbiór rzeczywistości, kształtują postawy i determinują oceny. Przeprowadzone badanie miało sprawdzić, czy emocje w zależności od ich rodzaju (pozytywne lub negatywne) wpływają na dystans interpersonalny. W badaniu wzięło udział 40 osób: 22 kobiety i 18 mężczyzn w wieku od 20 do 51 lat, (M=25 SD=7,48). Analizy korelacji związku emocji z dystansem konwersacyjnym wykazały różnicę na granicznym poziomie istotności statystycznej (t(38) =

1,92; p = 0,06). Oznacza to, że osoby którym indukowano emocje negatywne mogły wykazywać większy dystans konwersacyjny (M1 = 64,7) niż osoby którym indukowano emocje pozytywne. (M2 = 54,2). W przypadku emocji pozytywnych i badanego dystansu minimalnego, analiza korelacji nie wykazała istotnych statystycznie różnic pomiędzy grupami (U = 166,00; p = 0,36). Wykazano także związki pomiędzy indukowanymi emocjami a emocjami podczas zbliżania się, oceną neutralnie nastawionej osoby i postawą względem niej.
