Variabilidade morfológica foliar entre estágios de desenvolvimento em Allophylus edulis e Cupania vernalis (Sapindaceae) de floresta ombrófila mista
Authors: De Melo Júnior Joao Carlos Ferreira , Torres Boeger Maria Regina , Vieira Willyan , Matilde Silva Maiara
Published: April 2019

A radiação luminosa pode ser considerada, dentre os fatores ambientais aos quais as plantas estão expostas, aquele que apresenta maior heterogeneidade espacial e temporal, impulsionando nas plantas alterações morfológicas e anatômicas que melhoram a captação e a utilização desse recurso. O presente trabalho teve como objetivo discutir, numa perspectiva funcional, as alterações estruturais e de plasticidade em folhas de duas espécies dominantes em floresta ombrófila mista, encontradas em distintos níveis de exposição à luz, em diferentes estágios de crescimento. Parâmetros morfológicos e anatômicos foram medidos em dez folhas de cada espécie, para cada estágio de crescimento, sendo utilizada A nova para comparação das médias. Plantas adultas mais expostas à radiação, quando comparadas com plântulas, apresentaram menor área foliar, maiores densidadesfoliar e estomática e de espessura do parênquima paliçádico. Algumas inversões observadas em indivíduos jovens e em fase de plântulas sugerem que há um maior investimento em crescimento do que em produção fotossintética. Os caracteres mais plásticos foram a área e o peso foliar e a densidade estomática. Os resultados indicam, para as duas espécies, variações morfoanatômicas e fisiológicas que podemmelhorar a captação de luz e maximizar o aproveitamento de tal recurso para o pleno desenvolvimento do vegetal.

Narrativa e experiência: a escrita autobiográfica de pessoas em condição crônica de doença
Authors: Silveira Bruna Rocha
Published: April 2019

A narrativa autobiográfica, uma forma de compartilhar experiências, que são individuais, pode ser um importante mecanismo na construção de identidades e trazer um sentimento de pertencimento. Esse instrumento pode se mostrar ainda mais pujante quando falamos da escrita de pessoas em condição crônica de doença. Pensando nesses sujeitos, que possuem doenças incuráveis e que escrevem suas experiências, este artigo trabalha a motivação de uma escrita que envolve mexer com memórias dolorosas do vivido. Para tanto, são trazidos à discussão teóricos da escrita autobiográfica e da experiência para pensar duas obras literárias contemporâneas nacionais: Pulmão de aço – uma vida no maior hospital do Brasil (2012), de Eliana Zagui, e Um palhaço na boca do vulcão (2014), de Nando Bolognesi. Acredita-se que a escrita autobiográfica de experiências com a doença ajuda a construir o “eudoente”, uma identidade de passagem não para um eu verdadeiro, mas para uma realidade que se vive. Assim, essa ferramenta mostra-se como importante formador identitário que, no momento em que é compartilhado com a sociedade, apresenta modelos éticos de viver com essa diferença social.

Authors: Rahmati Maryam , Alipanahi Zahra , Mozafari Masoud
Published: April 2019

Background:

Over the past two decades, there have been substantial progress and a growing body of research on using natural polymeric biomaterials in emerging biomedical applications. Among different natural biopolymers, polysaccharides have gained considerable attraction among biomedical scientists and surgeons due to their biocompatibility, biodegradability, anti-inflammatory, and antimicrobial properties. In recent years, algalbased polysaccharides including agar, alginate, and carrageenan, have been broadly suggested for different biomedical applications.

Methods:

The aim of this paper is discussing various possible applications of algal-based polysaccharides in biomedical engineering particularly in controlled drug delivery systems. The main properties of each algal polysaccharide will be discussed, and particular drug delivery applications will be presented.

Results:

Algal polysaccharides can be detected in a group of photosynthetic unite as their key biomass constituents. They provide a range of variety in their size, shape, liquefaction, chemical stability, and crosslinking ability. In addition, algal polysaccharides have shown exceptional gelling properties including stimuli-responsive behavior, softness, and swelling properties.

Conclusion:

All the mentioned properties of alga polysaccharides lead to their successful usage in biomedical applications specially targeted and controlled drug delivery systems such as particles, capsules, and gels.
Lattice Thermal Conductivity Modelling of a Diatomic Nanoscale Material
Authors: Awad Adil H.
Published: April 2019

Introduction:

A new approach for expressing the lattice thermal conductivity of diatomic nanoscale materials is developed.

Methods:

The lattice thermal conductivity of two samples of GaAs nanobeam at 4-100K is calculated on the basis of monatomic dispersion relation. Phonons are scattered by nanobeam boundaries, point defects and other phonons via normal and Umklapp processes.

Methods:

A comparative study of the results of the present analysis and those obtained using Callaway formula is performed. We clearly demonstrate the importance of the utilised scattering mechanisms in lattice thermal conductivity by addressing the separate role of the phonon scattering relaxation rate. The formulas derived from the correction term are also presented, and their difference from Callaway model is evident. Furthermore their percentage contribution is sufficiently small to be neglected in calculating lattice thermal conductivity.

Conclusion:

Our model is successfully used to correlate the predicted lattice thermal conductivity with that of the experimental observation.

Authors: Pathak P. K. , Dhami A. J. , Chaudhari D. V.
Published: April 2019

A study was carried out on nine healthy mature breeding bulls (3 each of Gir, Surti and Murrah breed) to evaluate their fresh and frozen semen quality and their interrelationships. The ejaculates immediately after collection were evaluated
for routine physico- morphological attributes, including HOS test. The ejaculates (n=72) having >75% initial motility were diluted @ 80 million sperm/ml using TFYG extender and the French mini straws filled were frozen in liquid nitrogen vapour
using a programmable biofreezer. Thawing of straws was done at 37°C for 30 sec and assessed for freezability by conventional technique. All the cattle and buffalo bulls donated consistently normal thick creamy yellow and thick milky white semen,
respectively. In Gir, Suti and Murrah bulls (n=24 ejaculate each) the seminal attributes such as ejaculate volume (6.69±0.17, 3.12±0.10 and 3.96±0.16 ml, p less than 0.01); initial motility (80.21±0.88, 84.58±0.60 and 84.38±0.76 %, p less than 0.01);
total sperm output/ejaculate (9013.85±265.32, 3935.49±259.63 and 5366.48±332.99 million, p less than 0.01) and live sperm (84.71±0.83, 86.17±0.78 and 86.79±0.79 %, p less than 0.05) differed significantly. The mean percentages of post-thaw motile
sperm (53.29±1.56, 58.33±1.43 and 59.58±1.20, p less than 0.01); live sperm (59.00±1.95, 67.00±1.59 and 68.42±1.66 %, p less than 0.01); and HOS reactive sperm (48.25±0.78, 44.21±1.29 and 51.54±1.29 %, p less than 0.01) in Gir, Surti and Murrah bulls
semen also differed significantly. The variation among the bulls was significant for buffalo breeds in most of their fresh seminal attributes, except HOST, and for post-thaw motility, but not among Gir bulls. The important seminal attributes like
motility, live sperm and HOS reactive sperm of fresh and frozen-thawed semen were significantly and positively interrelated in all three breeds of bulls (r = 0.40 to 0.81, p less than 0.05 to 0.01), suggesting that motility and HOST of fresh semen
were good predictors of freezability of bovine semen.

Published: April 2019

The present study was carried out to evaluate the genetic polymorphism in Ovine MTNR1A of two tropical breeds ie., highly prolific NARI Suwarna sheep and Mandya sheep from southern peninsular region of India with respect to differential
fertility. Fifty animals from each breed were randomly selected and subjected to RsaI-RFLP analysis of exon-2 of Ovine MTNR1A. The study revealed monomorphic patterns in all the animals for both the breeds. PCR amplicon of 824 bp fragments with four
cut sites at 53 bp, 320 bp, 343 bp and 754 bp, resulted in 411 bp, 267 bp, 70 bp, 53 bp and 23 bp. Only presence of CC genotypes at rs406779174 SNP of Ovine MTNR1A in both the breeds supports non-seasonality in breeding of these animals and no
association of SNP with increased fecundity of NARI Suwarna sheep over Mandya sheep.
Late-Term Abortion and Retention of Placenta in Donkey (Equus acinus): A Report of Two Cases
Authors: Parmar S. C. , Patel J. A. , Chaudhari D. V. , Hadiya K. and A.J. Dhami K. , Dhami A. J.
Published: April 2019

The incidence of equine abortion is higher than that experienced by cattle. Abortion in equine may be infectious or non-infectious. Infectious agents such as bacteria, viruses or fungi may attack the fetus or its membranes, resulting in fetal
death and its expulsion. Non-infectious agents such as development of twins, torsion of umbilical cord or congenital anomalies may also result in death of the fetus and abortion (Kocabiyik et al., 2005). Many causes of late-term abortion including
infectious agents and placental abnormalities have been reported. Sometimes thorough post-abortion and post-delivery examination of the fetus, placenta and umbilical cord may reveal other causes that are not identified with laboratory procedures.
Retention of placenta is probably less common in equine because of simple, diffuse type of placentation and the strong uterine contractions aiding the separation of the villi from their maternal crypts and expelling the detached membranes (Roberts,
2004). Fetal membranes were defined as retained if they were not expelled completely within three hours after delivery in equine and has been regarded as a threat to the uterine health and general health of the equine. The reported sequelae of
retained fetal membranes range from none to metritis, laminitis, septicemia and death (Provencher et al., 1988). The present paper reports a successfully managed case of abortion at late-term gestation due to twisting of umbilical cord and retained
placenta in a donkey.

BACKGROUND

In order to address the challenges of chronic diseases, Beijing Municipal Government promoted intelligent family physician optimized collaborative model ( IFOC ) schema, which is poised to implement the patient-centered healthcare model, supported by intelligent chronic disease management system. The Fangzhuang community health service center is a National Demonstration Community Health Service Center in China, laid emphasis on the patient-centered model service, initiated, piloted and promoted IFOC schema optimize management of chronic diseases.

OBJECTIVE

To explore the effect of an intelligent family physician optimized collaborative model on selected hypertension patients of Fangzhuang Community in Beijing.

METHODS

This retrospective study used de-identified data of hypertension patients from the database of Fangzhuang community health service center. A comparative study pre- and post-implementation of IFOC for 2 years was performed to evaluate standardized management rate of blood pressure (BP), BP values, BP control rate, lifestyle changes and blood lipid levels. Continuous variables and categorical variables were analyzed using paired t-test and χ2 test, respectively.

RESULTS

A total of 6929 hypertension cases met inclusion/exclusion criteria. Compared with the pre-index period, standardized management rate increased from 34.4% to 67.4% in the post-index period (p < 0.001). SBP decreased from 144.10 mmHg to 141.38 mmHg (p < 0.001). BP control rate of the high-risk patients and overall BP control rate enhanced from 35.2% to 48.8%, from 44.7% to 49.9% , respectively (both p < 0.001). BMI decreased from 25.31 kg/m² to 24.65 kg/m².Exercise frequency increased from 2.83 times/week to 5.39 times/week; exercise duration increased from 20.03 min/d to 31.93 min/d; salt intake decreased from 9.56 g/d to 6.81 g/d; amount of cigarette smoking decreased from 11.31/d to 7.16 /d (all p < 0.005). TC decreased from 5.36 mmol/L to 4.65 mmol/L, LDL-C decreased from 3.35 mmol/L to 3.07 mmol/L (both p< 0.001), TG decreased from 1.79 mmol/L to 1.66 mmol/L (p= 0.021).

CONCLUSIONS

IFOC is an effective model in the management of hypertension and should be promoted and popularized by the Community Health Service Center in China as well as in other developing countries.

Published: April 2019

Background and objectives

Systemic inflammation modulates cardiovascular disease risk and functionality of HDL in the setting of CKD. Whether interventions that modify systemic inflammation can improve HDL function in CKD is unknown.

Design, setting, participants, & measurements

We conducted a post hoc analysis of two randomized, clinical trials, IL-1 trap in participants with GFR 15–59 ml/min per 1.73 m2 (study A) and IL-1 receptor antagonist in participants on maintenance hemodialysis (study B), to evaluate if IL-1 blockade had improved the anti-inflammatory activity (IL-6, TNF-α, and Nod-like receptor protein 3), antioxidant function (superoxide production), and net cholesterol efflux capacity of HDL. HDL function was measured using LPS-stimulated THP-1 macrophages or peritoneal macrophages of apoE-deficient mice exposed to the apoB-depleted, HDL-containing fraction obtained from the plasma of the study participants, collected before and after the interventions to block IL-1 effects. Analysis of covariance was used for between group comparisons.

Results

The mean age of the participants was 60±13 years, 72% (n=33) were men, and 39% (n=18) were black. There were 32 CKD (16 IL-1 trap and 16 placebo) and 14 maintenance hemodialysis (7 IL-1 receptor antagonist and 7 placebo) participants. Compared with placebo, IL-1 inhibition, in study A and B reduced cellular expression of TNF-α by 15% (P=0.05) and 64% (P=0.02), IL-6 by 38% (P=0.004) and 56% (P=0.08), and Nod-like receptor protein 3 by 16% (P=0.01) and 25% (P=0.02), respectively. The intervention blunted superoxide production in the treated arm compared with placebo, with the values being higher by 17% in the placebo arm in study A (P<0.001) and 12% in the placebo arm in study B (P=0.004). Net cholesterol efflux capacity was not affected by either intervention.

Conclusions

IL-1 blockade improves the anti-inflammatory and antioxidative properties of the HDL-containing fraction of plasma in patients with stages 3–5 CKD, including those on maintenance hemodialysis.

Coding Family Medicine Residency Clinic Visits, 99213 or 99214? A Residency Research Network of Texas Study
Authors: Young Richard A. , Holder Sarah , Kale Neelima , Burge Sandra K. , Kumar Kaparaboyna A.
Published: April 2019

Background and Objectives: The purpose of this study was to characterize Current Procedural Terminology (CPT) coding patterns for professional services in family physician (FP) residency clinics.
Methods: Trained assistants directly observed during every other FP-patient encounter in 10 clinics affiliated with eight residencies of the Residency Research Network of Texas. Three investigators later independently coded each visit for the highest code level reasonably allowed. The primary outcome was the number of clinic visits that were actually coded as a CPT 99203/213 that could have been coded at a higher level.
Results: In 850 physician-patient encounters where the CPT code billed was identified, the investigators completely agreed on the allowable code 93% of the time. Overall, a 99203/13 or lower or preventive services code was billed in 651 visits (76.6%), more commonly in resident visits (515/570 [90.4%] vs 136/280 for faculty [48.6%], P<.001). There were 476/660 (72.1%) visits coded at a 99213 or less that could have been coded as a 99204/214 or higher. This was more common in resident visits 385/434 (88.7%), but there was undercoding in faculty patients as well 91/226 (40.3%). We found very few cases of overcoding—16 total.
Conclusions and relevance: FPs coding patient encounters in residency clinics undercode for their work, which leads to decreased clinic revenue. This may be because the primary care exception is felt to be too onerous to bill for higher-paid codes, or a lack of knowledge of CMS coding rules among residents and faculty, or other reasons.
Reflexões sobre o game Divertida Mente na Rádio Disney e o simulacro de Baudrillard
Authors: Avelar Kamilla , Prata Nair
Published: April 2019

Jean Baudrillard cunhou os conceitos de simulação e simulacro como substitutos da realidade. Para o autor, o que existe são representações que assumem por vezes o caráter da neo-realidade ou hiper-realidade. A construção da hiper-realidade é mediada pela máxima exploração do significante resultando em fragmentos da realidade. A partir da explanação dos conceitos, este artigo pretende apresentar o aplicativo Rádio Disney e analisar o game Divertida Mente, que integra o aplicativo da rádio. A pesquisa se desenvolve à luz das ideias cunhadas por Baudrillard e pela pesquisa exploratória. A partir desses elementos é possível concluir que o aplicativo é um suporte com capacidades de criar e recriar situações que representam a magia em um exercício autor-referencial.Palavras-chave: Simulacro.

A estrutura do poder da mídia na contemporaneidade: uma análise triádica do dispositivo midiático
Authors: Ruggieri Ana Luísa
Published: April 2019

A partir do conceito foucaultiano de dispositivo trabalhado por Agamben (2005), pode-se entender a mídia como um dispositivo: o dispositivo midiático, conceito defendido a partir das ideias de Gerzson (2007), Marques (2008) e Berger (1996). Tendo em vista a sociedade midiatizada que vivemos, em que a mídia perpassa e pauta todas as interações sociais, este artigo pretende analisar como se estrutura o poder da mídia de referência na sociedade contemporânea a partir de uma análise triádica do dispositivo midiático, com observações a respeito das dimensões semiolinguística, socioantropológica e técnico-tecnológica, propostas por Klein (2007).Palavras-chave: Mídia.

Memes e contracultura: a reconfiguração de narrativas hegemônicas na semiosfera
Authors: Souza Tássia Aguiar de
Published: April 2019

Estudo sobre a produção e circulação de memes no âmbito da contracultura, enquanto produto de reconfiguração material e imaterial da memória da mídia. A pesquisa tem por objetivo situar os memes na semiosfera da cultura e analisar seu uso enquanto objeto de resistência política no Brasil, a partir da retomada de discursos historicamente hegemônicos, e sua relação com gêneros narrativos utilizados n’O Pasquim. Para tal, tomamos como referencial teórico o conceito de semiosfera, de Lótman, e a proposta de uma história não-linear desenvolvida por W. Benjamin. A metodologia parte de um levantamento de memes sobre a atual crise política no Brasil feita pelo jornal El País em sua plataforma online. Concluímos com esse trabalho que a produção de memes nasce materialmente de gêneros como a charge e resulta na propagação polissêmica dos discursos hegemônicos em circulação.Palavras-chave: Contracultura. Discurso. Meme. Memória. Semiosfera.
Fora da educação não há salvação: análise discursiva dos lemas “Brasil, Pátria educadora” e “Brasil. Ordem e progresso”
Authors: Santos Luciana Rocha dos , Ribeiro Augusto Gonçalves
Published: April 2019

A proposta do trabalho é realizar a análise de discurso a partir dos lemas de governo “Brasil, Pátria educadora”, da ex-presidente Dilma Rousseff e “Brasil. Ordem e progresso”, do atual presidente Michel Temer, com base no discurso da presidente e em matérias publicadas em sites e blogs, que se referem a época do anúncio do segundo mandato da presidente até o atual governo. Os pressupostos teóricos da análise do discurso, tais como ethos e interdiscurso, se fundamentam em Maingueneau, Bakhtin, Orlandi e Fiorin. Nessa perspectiva, a análise consistirá em verificar como os lemas de governo significam e/ou se inter-relacionam considerando os diversos sujeitos e contextos. Pretendemos, ultrapassar a opacidade da materialidade discursiva e interdiscursiva dos enunciados na contemporaneidade.Palavras-chave: Análise do discurso. Interdiscurso. Cenas enunciativas. Lemas de governo.
