Authors: Amirzargar Nasibeh , Heidari-Soureshjani Saeid , Yang Qian , Abbaszadeh Saber , Khaksarian Mojtaba
Published: August 2019

Background:

Hypoxia and anoxia are dangerous and sometimes irreversible complications in the central nervous system (CNS), which in some cases lead to death.

Objective:

The aim of this review was to investigate the neuroprotective effects of medicinal plants in cerebral hypoxia and anoxia.

Methods:

The word hypox*, in combination with some herbal terms such as medicinal plant, phyto* and herb*, was used to search for relevant publications indexed in the Institute for Scientific Information (ISI) and PubMed from 2000-2019.

Results:

Certain medicinal plants and herbal derivatives can exert their protective effects in several ways. The most important mechanisms are the inhibition of inducible nitric oxide synthase (iNOS), production of NO, inhibition of both hypoxia-inducible factor 1α and tumor necrosis factor-alpha activation, and reduction of extracellular glutamate, N-Methyl-D-aspartic and intracellular Ca (2+). In addition, they have an antioxidant activity and can adjust the expression of genes related to oxidant generation or antioxidant capacity. These plants can also inhibit lipid peroxidation, up-regulate superoxide dismutase activity and inhibit the content of malondialdehyde and lactate dehydrogenase. Moreover, they also have protective effects against cytotoxicity through down-regulation of the proteins that causes apoptosis, anti-excitatory activity, inhibition of apoptosis signaling pathway, reduction of pro-apoptotic proteins, and endoplasmic reticulum stress that causes apoptosis during hypoxia, increasing anti-apoptotic protein, inhibition of protein tyrosine kinase activation, decreasing proteases activity and DNA fragmentation, and upregulation of mitochondrial cytochrome oxidase.

Conclusion:

The results indicated that medicinal plants and their compounds mainly exert their neuroprotective effects in hypoxia via regulating proteins that are related to antioxidant, anti-apoptosis and anti-inflammatory activities.
A Microwave Accelerated Sustainable Approach for the Synthesis of 2-amino-4H-chromenes Catalysed by WEPPA: A Green Strategy
Authors: Hiremath Prashant B. , Kamanna Kantharaju
Published: August 2019

Background:

The agricultural wastes as a source offer an excellent alternative to replace many toxic and environmentally hazardous catalysts, due to their least toxicity, ease of biodegradability, and ability to act as a greener catalytic medium. Some of the agro-waste based catalysts reported are BFE, WERSA, WEB, and WEPBA. 2-Amino-4H-chromene derivatives are promising biologically potent heterocyclic compounds, due to their medicinal applications such as antimicrobial, anti-inflammatory, antibacterial, antiviral, anticancer, antidiuretic, anticoagulant and antianaphylactic activities. The present work describes a microwave accelerated, efficient, eco-friendly and economical approach for the synthesis of 2-amino-4H-chromenes through condensation of substituted arylaldehyde, malononitrile and resorcinol/naphthol catalyzed water extract of pomegranate peel ash (WEPPA) under microwave irradiation. The reaction completed within 3-6 min with good to excellent yield of product isolation. The final product isolated by simple filtration and recrystallization gave a spectroscopically pure form of product and did not require further purification.

Methods:

The pomegranate peel ash water extract as an agro-waste derived catalyst was employed under microwave irradiation for the economical synthesis of 2-amino-4H-chromene derivatives.

Results:

The reported agro-waste based catalyst was obtained in the absence of external base, additives and solvent-free synthesis of 2-amino-4H-chromene using aryl aldehyde, malononitrile and resorcinol/ naphthol under microwave irradiation. WEPPA acts as a solvent media and catalyst, as it plays a dual role in the synthesis of 2-amino-4H-chromenes.

Conclusion:

We established an efficient, simple, agro-waste based catalytic approach for the synthesis of 2-amino-4H-chromene derivatives from the condensation of arylaldehyde, malononitrile and resorcinol/α-naphthol/β-naphthol employing WEPPA as an efficient catalyst under microwave synthesis. The method has found to be a greener, economic and eco-friendly approach for the synthesis of chromene scaffolds. The advantages of the present approach are solvent-free, no external metal, chemical base free, short reaction time and isolated product in good to excellent yields. The catalyst is agro-waste derived, which has abundant natural sources available, thus making the present approach a greener one.

AbstractA comparison of the features of electron transport in diodes based on 6-, 18-, 30-, 70-, and 120-period GaAs/AlAs superlattices with a similar design is performed. However, the number of periods and diode areas are different. The values of the parasitic resistances of the near-contact diode regions are correlated, and the specific voltage drop across one superlattice period is determined for all special points in the current–voltage characteristics of the diodes. The mechanism of the appearance of stable current oscillations in diodes based on 6-, 18-, 30-, 70-, and 120-period GaAs/AlAs superlattices with a high doping level is investigated.

Published: August 2019

AbstractThe states of double acceptors in HgTe/СdHgTe heterostructures containing quantum wells are theoretically investigated taking into account the substantial difference in the values of the permittivities of the barrier and quantum-well layers. The effect of such a difference and the charge induced at the heterointerfaces arising from it are described with the image-charge potential. Calculation shows a significant change in the binding energy of the acceptor centers—mercury vacancies due to the induced charge; the ionization energies of mercury vacancies are in good agreement with the position of the spectral features in the photoluminescence spectrum of the HgTe/CdHgTe heterostructures containing quantum wells.

A method for the synthesis of magnetoplasmonic crystals containing two Ag gratings with the structure (Au / BIG) 2, in which the plasmon lattices of gold are displaced relative to each other by half the period, is presented. Gold films with a thickness of about 40 nm are formed by the method of ion-beam sputtering – deposition, and the adhesive properties of the film make it possible to carry out dimensional etching with a sharply focused ion beam. It was shown that the synthesis of the second plasmon lattice located above the garnet layer of 100 nm thick, preserves the periodicity of the first Au lattice, however a significant influence of the diffusion processes on the lower Au lattice is observed, which leads to a decrease in its density. The dependence of the transmission magneto-optical effect on the thickness of the upper lattice and the presence of an encapsulating Ta2O5 layer is investigated

The vertical components of the vector potential of an electromagnetic wave for a two-layer strongly inductive impedance medium are determined. The solution is presented as the Sommerfeld integral. The singular points of this integral were determined using the effective parameters. The question of the phase speed of a surface electromagnetic wave is considered. It is shown that it is always less than the light speed in a vacuum. This means that surface electromagnetic waves are not Zenneck waves, whose phase speed is greater than the light speed, like electromagnetic waves in waveguides.

The effect of gamma irradiation on the optical properties of layered TlGaSe2 and TlInS2 crystals in the wavelength range of 400–1,100 nm at 300 K is studied. From the analysis of optical absorption spectra, the energies of direct and indirect optical interband transitions before and after gamma irradiation are determined. It is shown that as the gamma-irradiation dose is accumulated in the range of 0–25 Mrad by TlGaSe2 and TlInS2 single crystals, the energies of direct and indirect allowed optical transitions increase from Egd = 2.06 eV and Egi = 1.90 eV at D = 0 Mrad to Egd = 2.11 eV and Egi = 1.98 eV at D = 25 Mrad for TlGaSe2 and Egd = 2.32 eV crystals and Egi = 2.27 eV at D = 0 Mrad to Egd = 2.35 and Egi = 2.32 eV at D = 25 Mrad for TlInS2 crystals. A decrease in the transmittance at doses from 0 to 5 Mrad and a further increase in the transmittance at the radiation dose D = 25 Mrad are observed.

Published: August 2019

AbstractWe successfully fabricated polycrystalline zinc oxide catalyst-free nanorods by a successive ion layer adsorption and reaction process. We measured their optical transmittance, reflectance and thickness in addition to performing X-ray diffraction and probing film microscopic topology. We extracted different optical constants such as absorption coefficient, band gap, complex refractive index and complex dielectric function and inferred the behavior of the optical conductivity and show the supremacy of the obtained ZnO nanostructure over a bulk material. It turns out that it is possible to obtain ZnO nanorods ultra-thin film with optical quality almost similar to those obtained by a contaminant metal catalyst approach requiring extra cost.

AbstractTo identify the signs that distinguish natural diamonds from artificial diamonds, a comparative analysis of the luminescence spectra with regards to the Q factor, center of gravity, bandwidth parameter, and energy losses in the diamond crystal lattice under conditions of ohmic and dielectric relaxation of luminescence is performed. The phenomenon of resonant luminescence in the femtosecond time range is detected in diamond. It is established that natural and artificial diamonds noticeably differ in the relaxation frequency and in the energy of resonant radiation.
Terrorism and Latin-American Stocks Markets
Authors: Magner Nicolás S. , Roa Cinthia K.
Published: August 2019

This paper investigates the effects of major terrorist attacks of the last 20 years on a set of stocks listed at Latin-American stock markets. Utilizing the capital market model, we calculate abnormal returns during the day of the terror attacks for 115 stocks listed in 6 Latin-American countries. In this sense, we appreciate different reaction between countries, where Brazil, Peru, and Chile have a significant market reaction of terrorism. These results promote international diversification and the use of this loss to avoid significant capital losses. However, the results are limited by the validity of the capital market model. This paper has important implications for international investors and their investment risk management strategies. Despite the frequency of terrorist events, this is the first work that addresses a wide range of these in Latin American countries. The main conclusion is that there is a negative effect of terrorist events on Latin American markets, but this effect is mixed; there is a negative and significant impact of the US terrorist attacks and a weak and non-significant effect when the attacks occur outside the US.
Fast Prediction of Deterioration and Death Risk in Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease Using Vital Signs and Admission History: Retrospective Cohort Study
Authors: Zhou Mi , Chen Chuan , Peng Junfeng , Luo Ching-Hsing , Feng Ding Yun , Yang Hailing , Xie Xiaohua , Zhou Yuqi
Published: August 2019

Background

Chronic obstructive pulmonary disease (COPD) has 2 courses with different options for medical treatment: the acute exacerbation phase and the stable phase. Stable patients can use the Global Initiative for Chronic Obstructive Lung Disease (GOLD) to guide treatment strategies. However, GOLD could not classify and guide the treatment of acute exacerbation as acute exacerbation of COPD (AECOPD) is a complex process.

Objective

This paper aimed to propose a fast severity assessment and risk prediction approach in order to strengthen monitoring and medical interventions in advance.

Methods

The proposed method uses a classification and regression tree (CART) and had been validated using the AECOPD inpatient’s medical history and first measured vital signs at admission that can be collected within minutes. We identified 552 inpatients with AECOPD from February 2011 to June 2018 retrospectively and used the classifier to predict the outcome and prognosis of this hospitalization.

Results

The overall accuracy of the proposed CART classifier was 76.2% (83/109 participants) with 95% CI 0.67-0.84. The precision, recall, and F-measure for the mild AECOPD were 76% (50/65 participants), 82% (50/61 participants), and 0.79, respectively, and those with severe AECOPD were 75% (33/44 participants), 68% (33/48 participants), and 0.72, respectively.

Conclusions

This fast prediction CART classifier for early exacerbation detection could trigger the initiation of timely treatment, thereby potentially reducing exacerbation severity and recovery time and improving the patients’ health.
Radiofrequency-Assisted Liver Resection Versus Clamp-Crush Liver Resection: Protocol for an Updated Meta-Analysis and Systematic Review
Authors: El-Koubani Osman , McCann Mark , Christmas Daniel , Khanna Aakash , von Maydell Alexander
Published: August 2019

Background

Malignancy of the liver has historically meant a poor prognosis and remains the second most common cause of cancer-related deaths globally. Traditionally, hepatectomy has utilized the clamp-crush technique; however, this is associated with high incidence of postoperative complications. Many novel techniques have been developed—radiofrequency ablation and transarterial chemoembolization; however, these are not applicable to numerous cases. Clamp-crush liver resection (CCLR) remains the gold standard. Radiofrequency-assisted liver resection (RFLR) is a technique that aims to reduce mortality through bloodless liver resection. A systematic review was previously performed on RFLR but the results neither recommended nor refuted the use of RFLR owing to the lack of sufficient evidence from well-designed randomized controlled trials (RCTs) at the time.

Objective

The aim of the study is the meta-analysis and systematic review of recent studies comparing RFLR against CCLR.

Methods

Articles comparing RFLR and CCLR that were published from 2014 until 2019 will be reviewed and relevant data will be extracted and statistically analyzed through Review Manager 5 (by the Cochrane Collaboration) together with the results of the previous meta-analysis.

Results

Data collection is currently underway, with papers being screened. We hope to publish the results by the end of 2019.

Conclusions

Given the high mortality rates currently associated with liver resection, it is imperative that novel surgical techniques are undertaken and investigated so we can improve best practice guidance and outcomes.

La dimensión sonora de “el costumbre”. Una recorrido sinuoso en la Huasteca
Authors: Camacho Díaz Gonzalo
Published: August 2019

Las prácticas rituales poseen un “rostro sonoro” que en varias ocasiones pasa desapercibido o es descrito tangencialmente en los estudios antropológicos. En el presente artículo se explora la dimensión sonora del sistema ritual de la región Huasteca, denominado “el costumbre”. Se muestran los diferentes complejos sígnicos que se configuran y transmiten a partir de los sonidos, que al ponerse en escena refuerzan el sentido general de cada uno de los rituales que los integran. Este estudio explora cómo la música trae a la memoria un conjunto de vivencias que se entrelazan para dar lugar a una experiencia presente, cargada de una fuerte emoción. Emotividad que hace verosímil el mundo sagrado.Abstract: Ritual practices have a “sound face” which is frequently unnoticed or is tangentially described in anthropological studies. This paper explores the sound dimension of the ritual system in the Huasteca region, called “el costumbre”.  We present the different sign systems, formed and transmitted by sounds, that when staged reinforce the general meaning of each one of the included rituals. We explore how music brings to mind a collection of experiences that are interlaced in order to create a new experience, charged with strong emotion. These emotions make the sacred world plausible.Résumé : Les pratiques rituelles possèdent un « visage sonore » souvent méconnu, que les études anthropologiques n’abordent souvent qu’en passant. Cet article explore la dimension sonore du système rituel dénommé El Costumbre (« le coutume ») de la région de la Huasteca afin d’en extraire les différents complexes de signes, organisés et transmis à partir des sons, qui, une fois mis en scène, renforcent le sens général de chacun des rituels dont ils font partie. Cette étude porte sur le rôle que joue la musique pour rappeler un ensemble de vécus qui s’entremêlent pour donner naissance à l’expérience présente et à sa charge émotionnelle. Charge émotionnelle qui rend le monde sacré plausible et vraisemblable.
Un texto vivo. Formas e interacciones del libreto de pastorela (Ihuatzio y Comachuén, Michoacán)

Published: August 2019

A partir del análisis de dos casos ejemplares y de observaciones de campo en diferentes pueblos purépechas, se argumenta sobre el valor antropológico, las interacciones y usos peculiares del libreto de pastorela. El libreto se relaciona con tres manuscritos antiguos en lengua tarasca, y con los que se utilizan en otras danzas y otros rituales indígenas, donde la palabra escrita es importante –y no solamente la palabra hablada o representada en imágenes, como establecieron los estudios clásicos– para el desenvolvimiento, sentido y alcances del ritual. El corolario es una reflexión sobre el poder de un objeto –el libreto–, para desafiar distinciones binarias: objeto-sujeto, material-inmaterial, y lo que se ha esta­blecido como eficacia, causas o efectos del ritual. Abstract: Based on the analysis of two exemplary cases and on field observations in different Purépecha villages, we examine the anthropological value, interactions and peculiar uses of the Christmas play script scenario. This scenario is related to three ancient manuscripts in Tarascan language, and to those used in other dances and Indian rituals, in which the written word –and not only the spoken word or the word represented in images, as established in classic studies– is important for the development, sense, and significance of the ritual. The corollary is a reflection on the power of an object –script scenario– to challenge binary distinctions: object-subject, material-immaterial, and to prompt us to rethink what has been established as efficacy, causes or effects of the ritual as anthropological problems. Résumé : À partir de cas concrets et d’observations de terrain menées dans différents villages purépechas, cette étude aborde la valeur anthropologique, les interactions et les usages particuliers donnés au livret de pastourelle. Ce dernier est associé à trois anciens manuscrits rédigés en langue tarasque et aux autres textes utilisés dans le cadre de danses et de rituels autochtones où la parole écrite joue un rôle important – contrairement à ce qu’établissent certains classiques, la parole ne se limite pas à l’oralité ou à la représentation en images – dans le déroulement du rituel, pour son sens et sa portée. En corollaire, l’article développe une réflexion sur le pouvoir de l’objet – ici, le livret – pour interroger les distinctions binaires : objet/sujet, matériel/immatériel, et pour repenser en tant que problèmes anthropologiques ce qui avait été pris pour de l’efficacité, les causes ou les effets du rituel.

A possibilidade de concessão de benefício previdenciário a famílias com crianças portadoras de necessidades especiais
Authors: Discacciati Ana Clara Gonçalves
Published: August 2019

O presente trabalho busca analisar juridicamente uma possível alternativa para a atual conjuntura de nascimento de crianças com microcefalia no Brasil: finda a licença-maternidade, qual tipo de assistência receberiam os pais que precisam se afastar do mercado de trabalho para acompanhar a criança com deficiência? Para tanto, primeiramente, propõe-se a análise da proteção jurídica destinada às crianças, tanto no âmbito internacional e nacional. Na segunda parte, apresentam-se as atuais perspectivas assistencialistas em relação aos infantes, bem como o estudo do Betreeungsgeld, parcela monetária oferecida pelo sistema social da Alemanha aos pais que ficam em casa com os filhos com idade de até três anos, em virtude do número insuficiente de creches para a demanda. Posteriormente, faz-se referência sobre a legislação destinada aos deficientes, físicos ou mentais, como o Estatuto da Pessoa com Deficiência (Lei nº 13.146/2015) e, por fim, questiona-se a possibilidade de introdução de um auxílio aos pais que não conseguem conciliar o exercício de atividade laboral com os cuidados que os filhos com necessidades especiais necessitam, por meio do método dedutivo, a fim de que, por meio da prática, uma construção legal estrangeira seja adequada ao sistema jurídico pátrio. Conclui-se que é dever do Estado prover um meio alternativo de subsistência às famílias com crianças com deficiências que não exercem algum tipo de trabalho remunerado até a inclusão das crianças nas escolas.

A Construção dos direitos na sociedade democrática liberal: o uso e os sujeitos do direito fundamental ao meio ambiente
Authors: Araripe Aline Bona de Alencar , Basso Ana Paula
Published: August 2019

A democracia liberal que se desenvolveu e se afirmou no ocidente, a partir do século XVIII, não existe separadamente do Estado Nacional, cuja base consiste numa identidade unitária. Dessa forma, surge a necessidade de atribuir cidadania aqueles sujeitos que adquirirem essa identidade unitária, entendendo por cidadania a proteção de direitos e a exigência de deveres. O direito fundamental ao meio ambiente conta com reconhecimento internacional, mas apesar disso, não é efetivamente garantido a todos os sujeitos. Neste artigo, analisa-se quem são os sujeitos de direito que possuem cidadania, a partir do processo de consolidação da democracia liberal, com o objetivo de verificar quem são os sujeitos que tem o direito fundamental ao meio ambiente efetivamente garantido.

Após um histórico acerca da teoria da separação dos Poderes, foi descrito o modo como foi recepcionada a independência do Poder Judiciário no ordenamento jurídico brasileiro. Neste contexto, é já adentrando ao final do texto, foram analisados os tópicos mais importantes do PLS 85/2017 (PL 7.596/2017). Assim, diante da referida problematização, buscou-se, com base na doutrina e na lei, ainda que sucintamente, evidenciar a importância de uma nova lei que limitará, tão somente, atuações políticas e ilegais por parte dos magistrados.
Observações preliminares sobre o acordo de não persecução penal: da inconstitucionalidade à inconsistência argumentativa
Authors: Andrade Mauro Fonseca , Brandalise Rodrigo Da Silva
Published: August 2019

Recentemente, o Conselho Nacional do Ministério Público publicou a Resolução nº 181, de 07 de agosto de 2017, onde apresentou uma nova regulamentação para a investigação criminal presidida pelo acusador público brasileiro. Dentre as novéis disposições lá presentes, o que vem chamando muito a atenção dos operadores do direito é o denominado acordo de não-persecução penal, que se constitui em um acordo de não oferecimento da acusação pelo Ministério Público, dependente do cumprimento das condições firmadas pela pessoa investigada e seu defensor. Em razão disso, o objetivo do presente estudo é analisar a viabilidade dos argumentos apresentados pelo Conselho Nacional do Ministério Público para inserir esse instituto em nosso país. Em um primeiro momento, será analisado o parâmetro internacional utilizado, de modo a observar se é correta a equiparação entre a realidade alemã e a realidade brasileira. Ao depois, será averiguada a correção do argumento sistêmico invocado. Por fim, será averiguada a conformidade constitucional do acordo presente naquela resolução. A título de conclusão, apontar-se-á a inconstitucionalidade do acordo de não-persecução penal, e sua incompatibilidade com os argumentos apresentados pelo próprio Conselho Nacional do Ministério Público.

Middle class and public services in Brazil: commodity boom, economic crisis, and protests for a better public transportation system
Authors: Carvalho Andre Castro
Published: August 2019

RESUMOO objetivo deste trabalho é estudar o baixo nível atual de qualidade dos serviços públicos no Brasil, a fim de identificar uma relação entre a má qualidade de tais prestações e os protestos que vêm ocorrendo cada vez mais frequentemente no país. Entre outras demandas, alguns protestos foram inicialmente contra a baixa qualidade dos serviços prestados à população, especialmente o transporte público. Uma das principais razões para essa insatisfação é a recente ascensão da classe média nos países em desenvolvimento. Essa ascensão está aumentando a parcela de participação nos processos decisórios (a classe média representa cerca de metade da população brasileira), e esse engajamento está moldando novas demandas por políticas públicas mais voltadas para seus valores. A classe média tem um forte poder de consumo de bens e serviços privados: essa influência levou as empresas privadas a modelar seus produtos e serviços de acordo com suas preferências, mas os governos ainda estão oferecendo serviços de menor qualidade do que a classe média está disposta a receber. Esse descompasso leva a uma constante insatisfação pública e pode continuar a causar novas manifestações contra as atuais políticas públicas. PALAVRAS-CHAVEServiços públicos. Manifestações e multidões. Classe média. Qualidade de vida. Países em desenvolvimento.ABSTRACTThe purpose of this paper is to study the current low level of quality of public services in Brazil, in order to identify a relation between the bad quality of such provisions and the protests that have increasingly taken place in the country. Among other requests, some protests were initially against the low quality of services provided to population, especially public transportation. One main reason for this dissatisfaction is the recent rise of the middle class in developing countries. Such ascension is increasing their share of participation in the decision-making processes (the middle class represents roughly half of the population in Brazil), and this engagement is shaping new demands for public policies oriented more towards their values. The middle class has a strong power of consumption of goods and private services: this influence led private companies to model their products and services to their preferences, but governments are still delivering lower quality services than the middle class is willing to receive. This mismatch leads to constant public dissatisfaction and may continue to cause further riots against the running of current public policies.  KEYWORDSPublic utilities. Riots and mobs. Middle class.

A teoria do direito natural no tempo pós-moderno
Authors: Correas Carlos I. Massini
Published: August 2019

RESUMOAssim como em quase todas as matérias, é conveniente fazermos um pouco de história para compreendermos a situação atual da teoria do direito. No caso deste trabalho, vamos remontar apenas até a Idade moderna, pois, como bem diz Daniel Innerarity, “a filosofia contemporânea transformou-se numa reflexão sobre a modernidade”. Esquematizando muito, por razões elementares de brevidade, podemos afirmar que é possível diferenciar três traços centrais na filosofia moderna: a) perda da noção teleológica de natureza; b) aparição da concepção moderna do sujeito; c) imanentização do pensamento. PALAVRAS-CHAVEDireito Natural.

In the case of this paper, we will remount only until Modern Age, for, as says correctly Daniel Innerarity, “contemporary philosophy has turned itself into a reflection on modernity”. Outlining considerably, for elementary reasons of brevity, we can affirm that it is possible to discriminate three central features in modern philosophy: a) the loss of the theological notion of nature; b) the emergence of the modern conception of the subject; c) the immanentization of thought.KEYWORDSNatural Law.

Use of the Femoral Vein as Insertion Site for Tunneled Hemodialysis Catheters

The femoral vein provides an alternative access site for insertion of tunneled hemodialysis catheters when conventional sites are not available. Tunneled femoral hemodialysis catheters have low primary patency rates and significant complications. Catheter retraction is a unique and common problem. However, the use of the femoral vein remains acceptable in those patients who have limited options for long-term hemodialysis.

Published: August 2019

The process parameters of laser remanufacturing technology have significant effects on the geometric characteristics of the single clad layer in the laser remanufacturing process. In this study, the effects of laser power, laser scanning velocity, and powder feeding rate on the geometry characteristics of a clad layer are investigated by depositing Inconel 718 powder on Inconel 718 alloy via coaxial laser cladding. Based on the experimental results, the mathematical models of geometry characteristics are created using the response surface methodology and checked by the analysis of variance. The verification results indicate that the predicted values coincide with the measured ones, which confirms the reliability effectiveness of the models derived from the regression analysis. Finally, the relationship between the main process parameters and geometric characteristics is studied. The modeling results show that laser power has a positive effect on all the geometry characteristics, while the powder feeding rate has a positive effect on the clad height and a negative impact on the width, depth, W/H (the ratio of clad width to height), and dilution rate of the clad layer. The scanning velocity has a positive effect on the W/H and dilution rate of the clad layer and a negative effect on the width, depth, and height of the clad layer.
Energy Efficient Particle Swarm Optimization Based Multipath Routing in WSN

Published: August 2019

Wireless Networks includes a larger advantage in today’s communication application like environmental, traffic, military, and health observation. To realize these applications it's necessary to possess a reliable routing protocol. discusses about the working of proposed energy efficient bandwidth aware shortest path routing protocol for multipath routing in wireless sensor network. The proposed algorithm is based for choosing energy efficient shortest path. In routing algorithm, route that have shortest path among multipaths selected by particle swarm optimization algorithm. Among these shortest paths, that path is selected which require minimum route selection parameter. The proposed algorithm uses distance as well as energy of nodes as a parameter to find optimum paths using particle swarm optimization. Among these selected paths, only one optimum path is selected which reduces the energy requirement of the network. According to this work there would be improvement in other parameters also such as end to end delay as well as throughput.

Published: August 2019

OBJECTIVE

To identify factors associated with dehiscence and mortality rates following gastrointestinal surgery in dogs.

ANIMALS

170 client-owned dogs that underwent gastrointestinal surgery from 2010 to 2016.

PROCEDURES

Medical records of all included dogs were reviewed to collect information on preoperative (breed, sex, age, body weight, American Society of Anesthesiologists [ASA] physical status classification, emergency status, and plasma lactate concentration), intraoperative (indication for surgery, type of surgery, and whether bacterial peritonitis was identified), and postoperative (development of dehiscence and survival status at 2 weeks after surgery) factors. Preoperative and intraoperative factors were evaluated for associations among each other and with postoperative factors.

RESULTS

Univariate analyses revealed that preoperative plasma lactate concentration increased with increasing ASA status, and lactate concentrations were significantly higher for nonsurvivors (mean ± SD, 4.6 ± 3.7 mmol/L) than for survivors (2.4 ± 1.7 mmol/L). Multivariate analysis controlling for age, body weight, and plasma lactate concentration revealed that dogs with an ASA status ≥ 3 were more likely to develop dehiscence after gastrointestinal surgery than were dogs with a lower ASA status (OR, 17.77; 95% confidence interval, 2.17 to 144.06). Multivariate analysis also revealed that dogs with an ASA status ≥ 3 or high lactate concentration were less likely to survive than were other dogs.

CONCLUSIONS AND CLINICAL RELEVANCE

These findings regarding ASA status and preoperative plasma lactate concentration and their associations with outcome may help clinicians to determine and provide optimal perioperative care to dogs requiring gastrointestinal surgery as well as to inform owners about prognosis.
Suprascapular nerve decompression for treatment of neuropathy in a bucking bull

Published: August 2019

CASE DESCRIPTION

A 3-year-old 639-kg (1,406-lb) American bucking bull was examined because of a 4-day history of right forelimb lameness that began after the bull sustained an injury to the right shoulder region while exiting the chute during a rodeo.

CLINICAL FINDINGS

A 10 × 10-cm soft tissue swelling was present over the right shoulder region. Ultrasonographically, the contour of the scapular spine, bicipital bursa, bicipital tendon, and greater tubercle of the humerus appeared unremarkable; the swelling appeared to be a hematoma overlying the distal aspect of the scapula. No external wounds, palpable joint effusion, or swellings were noted on examination of the distal portions of the limbs. The bull developed atrophy of the supraspinatus and infraspinatus muscles with lateral abduction of the shoulder joint when walking. Electromyography revealed decreased innervation to the supraspinatus and infraspinatus muscles consistent with suprascapular neuropathy.

TREATMENT AND OUTCOME

The suprascapular nerve was surgically decompressed by removing the entrapping hematoma and periosteum and performing a notch resection of the scapula; dexamethasone (40 mg) was administered prior to closure. The bull was discharged 5 days after surgery; no lameness was evident at the time of discharge. The owner was instructed to restrict the bull to a stall or small pen for 6 weeks. Four months after surgery, the muscle atrophy had substantially improved, and the bull returned to bucking.

CLINICAL RELEVANCE

Findings suggested that suprascapular neuropathy can develop in bulls secondary to injury and that suprascapular nerve decompression may improve nerve function, muscle atrophy, and gait.
Positive impact of clinical pharmacist interventions on antipsychotic use in patients on excessive polypharmacy evidenced in a retrospective cohort study
Authors: Stuhec Matej , Gorenc Katja
Published: August 2019

Objectives

Although antipsychotic prescribing in elderly patients using polypharmacy has not been studied in well-designed clinical trials and meta-analyses, there is an urgent need to monitor prescribing practice in this population. One of the possible approaches to optimize pharmacotherapy may be the involvement of clinical pharmacists (CPs). The aim of this research was to examine whether the involvement of a CP can improve treatment guidelines adherence and change the total number of medications per patient in older patients who are treated with excessive polypharmacy that includes antipsychotics.

Methods

This cohort retrospective study included older patients (65 years or older) treated with at least one antipsychotic and excessive polypharmacy (10 or more medications concurrently) between 2012 and 2014 in primary care. The main outcome measures were antipsychotic treatment guidelines’ adherence and the total number of medications per patient after the CP’s interventions. Only interventions including antipsychotics were studied in detail (i.e., discontinuation, switching, initiation, dose adjustment, change of another medication because of a drug-related problem). Data on diagnoses, patient pharmacotherapy and the CP’s interventions were obtained from clinical records and medical reviews. Age and acceptance of the CP’s interventions were used as predictive factors for antipsychotic treatment guidelines’ adherence.

Results

Forty-nine patients were included. The CP suggested 21 different interventions of which nine (42.8%) were accepted by the general practitioners. The number of medications that patients received decreased after the CP’s interventions (N of medications before: 15.4; N of medications after: 12.0, p < 0.05). The acceptance of the CP’s recommendations, but not age, improved antipsychotic treatment guidelines’ adherence (p = 0.041).

Conclusions

These results show that a collaborative care approach including a CP in primary care significantly improved the adherence to treatment guidelines. The results also support the implementation of this service in the Slovenian healthcare system, although more studies are needed.
