Published: April 2018

Nos dias atuais, com o poder das redes sociais, surge uma atividade empreendedora em que pessoas são capazes de formar opinião e auxiliar organizações, tanto na captação de clientes quanto no respeito aos seus desejos e necessidades. Embora recente, a atividade desempenhada por influenciadores digitais ganha expressividade no mercado conquistense. O objetivo do presente trabalho é, portanto, analisar o papel de influenciadores digitais em Vitória da Conquista, Bahia. A metodologia utilizada neste estudo é descritivo-exploratória e de natureza teórico-empírica. O instrumento de coleta de dados foi um questionário aplicado entre dezesseis blogueiras. Adotando o critério de acessibilidade, realizaram-se entrevistas com roteiro semiestruturado com cinco influenciadoras. Os dados receberam tratamento qualiquantitativo. Conforme evidenciam os resultados, as formadoras de opinião viabilizam um melhor relacionamento da organização com o seu público-alvo, além de facilitar a coleta de informações sobre os desejos e necessidades do potencial consumidor. Ademais, segundo as entrevistas e a apuração dos dados, as empresas aumentam a sua receita e ganham maior visibilidade.

Authors: Santos Thaís Amaral , Das Almas Rondinaldo Silva
Published: April 2018

O presente trabalho teve por objetivo analisar as exportações dos estados do Nordeste do Brasil entre os anos de 2005 e 2015, traçando um comparativo entre os resultados estaduais e os da região como um todo, o que forneceu um diagnóstico da situação dos estados nordestinos em relação à exportação dos principais itens que compõem a sua pauta, a saber: se os estados apresentam ou não vantagens comparativas e se possuem ou não especialização na produção desses itens. A análise foi feita utilizandose o método shift-share, com base nos dados fornecidos pela Secretaria do Comércio Exterior. Observou-se que a região apresenta pauta de exportações concentrada – tanto no que diz respeito aos produtos exportados quanto em relação às participações dos estados no total exportado –, destacando-se as commodities.
Crianças cometem lapsos da língua? Algumas evidências dos processos metafóricos e metonímicos desde as falas iniciais (Do children commit slips of the tongue? Some evidence regarding metaphoric and metonymic …)
Authors: Iliovitz Erica Reviglio , Ponte Juliana Galindo de Oliveira
Published: April 2018

Esse trabalho visa investigar se crianças podem cometer lapsos da língua. A motivação para esse trabalho partiu da necessidade de questionar uma convenção teórica adotada em uma pesquisa anterior (Iliovitz, 2001) levando em consideração os dados de uma outra pesquisa (Oliveira, 2004). O referencial teórico envolve Freud (1977, 1987), Saussure (1989), Jakobson (1971) e os processos metafóricos e metonímicos sob o enfoque interacionista de De Lemos (1992). A conclusão é que crianças estão sujeitas aos processos metafóricos e metonímicos desde as falas iniciais e, portanto, também podem cometer lapsos.
As formas de tratamento nominais rapaz e cara no falar de Fortaleza – CE: um estudo variacionista (The forst of personal pronouns rapaz and cara in the speech of Fortaleza - CE: a variationist study)
Authors: Araújo Aluiza Alves de , Guimarães Tatiane Araújo Almeida Studart , Pereira Maria Lidiane De Sousa
Published: April 2018

Neste trabalho, investigamos a variação entre as formas de tratamento nominais rapaz e cara no falar de fortaleza – CE, sob os alicerces teórico-metodológicos da sociolinguística variacionista (LABOV, 1994, 2006, 2008; WEINREICH; LABOV; HERZOG, 2006). Nosso objetivo é analisar a atuação de fatores linguísticos e extralinguísticos sobre o uso, principalmente, da forma de tratamento rapaz. Para tanto, utilizamos uma amostra de linguagem falada composta por 53 informantes extraídos do banco de dados do Projeto Norma Oral do Português Popular de Fortaleza (NORPOFOR). De um total de 130 dados, vimos que o uso da variante rapaz (65,60%) prevalece sobre o uso da forma cara (35, 40%). De igual modo, verificamos que, na amostra de fala estudada, os fatores extralinguísticos que mais favorecem o uso da variante rapaz foram, nesta ordem decrescente de importância: escolaridade (falantes com 0-4 anos e 5-8 anos de escolaridade), sexo (masculino) e faixa etária (falantes com 26-49 anos) e, dentre os fatores linguísticos, a posição da forma em relação ao verbo (termo isolado) se apresentou como aliado da forma rapaz.
UMA ANÁLISE DAS MARCAS DO PODER DISCIPLINAR NO COTIDIANO ESCOLAR DAS JUVENTUDES DO IFS
Authors: Nascimento Ana Paula Leite , Cruz Maria Helena Santana
Published: April 2018

O estudo analisou as marcas do poder disciplinar no cotidiano escolar das juventudes, evidenciando os investimentos na construção de corpos “dóceis” no contexto do IFS. Enfatizamos os fundamentos teóricos do poder disciplinar e seus investimentos na construção de corpos “dóceis”; e, problematizamos os regramentos escolares e o sistema disciplinar do IFS, trazendo à tona dados da análise documental do Regulamento da Organização Didática do IFS, e, da realidade socioeconômica dos/as estudantes, a fim de problematizarmos o controle e a regulação disciplinar. Caracterizou-se como uma pesquisa qualitativa e o materialismo histórico dialético enquanto método perpassou o estudo. Identificamos que a escola investe na produção de sujeitos homogêneos e de corpos “dóceis”, e, em razão disso não acolhe e pune por meio do poder disciplinar aqueles/as que apresentam corporalidades e identidades que contrariam a lógica homogeneizante e a lógica imposta de docilidade-utilidade.

CONTROVÉRSIAS JURÍDICAS E A PERSISTENTE DIVISÃO DO TRABALHO EM CRECHES PÚBLICAS:
Authors: Rosa Sanny Silva da , Andrade Fernanda Feliciano de
Published: April 2018

Este artigo discute a divisão do trabalho entre professoras e auxiliares de desenvolvimento infantil em creches públicas, a partir de reflexões sobre a indissociabilidade do binômio cuidar-educar colocado em relevo nos documentos oficiais desde a promulgação da Lei de Diretrizes e Bases de 1996. O texto problematiza os conflitos existentes entre os objetivos declarados na legislação brasileira e as práticas de atendimento em creches, onde persiste a divisão hierárquica das atribuições dos profissionais que trabalham com crianças de 0 a 3 anos. Com base em dados documentais e de campo, coletados em estudo realizado em creches do município de Mauá, região do Grande ABC Paulista, coloca-se em evidência os obstáculos jurídicos e políticos que se interpõem entre os discursos das orientações curriculares e pedagógicas oficiais e as condições necessárias para a sua concretização. Argumenta-se que a definição de regras claras que de fato eliminem as ambiguidades e controvérsias jurídicas que permitem a divisão de papéis no âmbito das instituições de educação infantil é a pedra-de-toque do propósito das políticas públicas de educação infantil de superar a dicotomia cuidar-educar e a herança assistencialista das creches brasileiras.
INCLUSÃO DO ALUNO COM DEFICIÊNCIA:
Authors: Machado Laêda Bezerra , Albuquerque Ednéa Rodrigues , Albuquerque Lia Matos Brito
Published: April 2018

Este artigo discute os resultados de uma pesquisa desenvolvida em Jaboatão dos Guararapes-PE e confronta o discurso legal e prática pedagógica inclusiva na escola, sob a perspectiva de profissionais e pais de alunos com deficiência. Trata-se de um fragmento de um estudo de caso qualitativo em que foram entrevistados 32 sujeitos. Fez-se uso de entrevistas associativas, que foram processadas analisadas com o auxílio do software Alceste. Os resultados indicaram que profissionais e pais de alunos com deficiência não legitimam o discurso legal sobre inclusão porque as condições para efetivá-lo não são asseguradas. Segundo os entrevistados, as mínimas condições de infraestrutura escolar, de acesso e de trabalho não são garantidas o que compromete a possibilidade de aprendizagem. Portanto, o avanço da legislação não assegura por si só a inclusão do aluno com deficiência.

A vida nua na penitenciária feminina da capital: um passeio pela obra prisioneiras
Authors: De Oliveira Monique Alves
Published: April 2018

Em 2017 é publicado o livro Prisioneiras de autoria de Dráuzio Varella, a proposta da obra é ser um relato a respeito do universo prisional feminino observado pelo autor durante seu trabalho como médico voluntário na Penitenciária Feminina da Capital. O objetivo da presente pesquisa é passear pela obra de Varella com um olhar crítico do sistema carcerário brasileiro na perspectiva de problematizar a realidade. O método adotado para desenvolvê-lo foi a revisão bibliográfica. Foucault (1987) quando analisa a prisão percebe o espaço prisional como um lugar de negação do direito, Agamben (2010), por sua vez, afirma que o direito carcerário não está fora do ordenamento jurídico, e enquanto desdobramento do direito penal constitui uma expressão do poder soberano. Em Agamben é no campo de concentração que se observa a negação do direito, sobretudo, na identificação da figura do homo sacer, o indivíduo que por ter sido alijado de seu significado social é matável, mas não sacrificável, ou seja, não possui dignidade para ser ofertado em sacrifício sendo perdoável a ação de tirar-lhe a vida nua. Por fim, é possível identificar nos indivíduos submetidos ao cárcere no Brasil, sobretudo as mulheres, dada a intensidade do seu abandono quando inseridas no sistema penitenciário, características desse Homo Sacer. Restando evidenciado esse cenário pode-se falar em um espaço de negação do direito, não na visão Foucaultiana, mas na perspectiva de Agamben que vislumbra um estado de exceção.
Membaca Perempuan dalam Hadis Misoginis: Usaha Kontekstualisasi Nilai Kemanusiaan
Authors: Muhtador Mohamad
Published: April 2018

Gender reading of misogynist hadiths in this case is aimed at uncovering models of understanding of the traditions of gender-biased prophets, the article not least of the prophetic traditions circulating in society with the style and expression of hatred against women. This has a negative impact on the potential development of women and the existence of sex. Therefore, in this position, the study of gender becomes very urgent to open the variety of understanding with different styles as an attempt to obtain justice and give a new color in understanding, so that interpretation does not become a single truth in understanding the teachings of religion, especially related to the hadith of the Prophet. The results of this study indicate that the gender relations in misogynical hadiths are an attempt to reread with a gender perspective that is more concerned with moral ideals in exploring the traditions of the Prophet, specifically with misogynist hadiths.

Syekh Wali Lanang sebagai PitÄmaha Raja Raja Jawa Studi Teks Babad GÄ•dhongan
Authors: Hakim Taufiq
Published: April 2018

The position of pitÄmaha or ancestor in the Babad tradition has an important role. One of them is the position of Sheikh Wali Lanang in Babad GÄ•dhongan (hereinafter abbreviated as BG). The guardian of the prophet's teachings is narrated later by the king of Java. This research seeks to understand the position of Sheikh Wali Lanang as the pitÄmaha of Javaâ€™s king in BG, a Javanese manuscript not yet widely known by the public generally. By presenting the historiography of Babad as a reconstructive historical source, and revealing the BG text philologically, it can be argued that the position of Sheikh Wali Lanang is a symbolic political movement by Paku Buwana III and Paku Buwana VII. The creation and transformation of BG are one of the kingdom's efforts to build a spiritual and spiritual culture after the fading of economic and political legitimacy resulting from the turmoil that occurred before. These two Surakarta kings indirectly also want to present themselves as the descendants of the Prophet, through Sheikh Wali Lanang who is the 21st descendant of the Prophet.Â

Degrees of separation properties in stratified L-generalized convergence spaces using residual implication
Authors: Pang Bin
Published: April 2018

By using the residual implication on a frame L, we develop a theory of
separation axioms in the category of stratified L-generalized convergence
spaces in the spirit of Lowen, i.e., we define for each space some degrees
of fulfilling T0, T1, T2 and regularity axioms from a logical aspect. These
degrees of separation axioms generalize the theory of separation axioms in
the sense of J?ger.
On strictly quasi-Fredholm linear relations and semi-B-Fredholm linear relation perturbations
Authors: Hafsa Bouaniza , Mnif Maher
Published: April 2018

In this paper we introduce the set of strictly quasi-Fredholm linear
relations and we give some of its properties. Furthermore, we study the
connection between this set and some classes of linear relations related to
the notions of ascent, essentially ascent, descent and essentially descent.
The obtained results are used to study the stability of upper
semi-B-Fredholm and lower semi-B-Fredholm linear relations under
perturbation by finite rank operators.
A new second-order corrector interior-point algorithm for P*(k)-LCP
Authors: Kheirfam B. , Chitsaz M.
Published: April 2018

In this paper, we propose a second-order corrector interior-point algorithm
for solving P*(k)- linear complementarity problems. The method generates a
sequence of iterates in a wide neighborhood of the central path introduced
by Ai and Zhang. In each iteration, the method computes a corrector
direction in addition to the Ai-Zhang direction, in an attempt to improve
performance. The algorithm does not depend on the handicap k of the problem,
so that it can be used for any P*(k)-linear complementarity problems. It is
shown that the iteration complexity bound of the algorithm is O ((1+k)3 ?
nL). Some numerical results are provided to illustrate the performance of
the algorithm.

Effect of graphene orientation on microstructure and mechanical properties of silicon nitride ceramics
Authors: Zhang Yubing , Xiao Guangchun , Yi Mingdong , Xu Chonghai
Published: April 2018

Mechanical properties and microstructure of graphene platelets reinforced
Si3N4 composites have been investigated and compared to monolithic Si3N4.
The microstructure shows that graphene platelets are parallel to each other
and perpendicular to the hot pressing direction. Fracture toughness and
flexural strength of composite with 1 wt.% graphene measured on polished
surface perpendicular to hot pressing direction are 8.7MPa?m1/2 and 892MPa,
respectively, which are increased about 14.5% and 20.2% compared with that
parallel to hot pressing direction. The anisotropy of microstructure and
mechanical properties of composites can be explained by the intrinsic
anisotropy of graphene as well as the crack deflection energy release rate
and the weak boundary bonding between graphene and Si3N4 caused by the
thermal expansion mismatch.
Effects of sintering temperature and holding time on the microstructure and electric properties of Ba(Zr0.3Ti0.7)O3 ceramics
Authors: Zhang Xiaoya , Chen Gang , Fu Chunlin , Cai Wei , Gao Rongli , Wang Fengqi
Published: April 2018

Ba(Zr0.3Ti0.7)O3 (BZT) ceramics was prepared by using conventional solid
state reaction. The effects of sintering temperature and holding time on the
crystal structure, surface morphology, dielectric, ferroelectric and
piezoelectric properties of the BZT ceramics were systematically
investigated. X-ray diffraction (XRD) results confirm single cubic perovskite
phase in all the sintered samples. Microstructure analysis using scanning
electron microscopy (SEM) reveals that the grain sizes increase with
increasing the sintering temperature. Dielectric spectroscopy performed in
the range of 20Hz to 2MHz at room temperature shows that the dielectric
constant increases with the sintering temperature and the dielectric constant
of the BZT ceramics sintered at 1400?C for 8 h is around 11500. The
ferroelectric hysteresis loops show that the coercive field decreases with
the holding time, while the remnant polarization does not change obviously.
The maximum strain is 0.023%for the sample sintered at 1400?C for 4 h. It is
found that the maximum value of the direct piezoelectric coefficient (d33) of
the BZT ceramics sintered at 1400?C for 8 h measured at room temperature is
36.7 pC/N.
Comparative structural and optical spectroscopic studies of Nd3+ ion doped LaF3 and their core/shell nanoparticles
Authors: Ansari Anees , Labis Joselito , Manthrammel Mohamed
Published: April 2018

LaF3 :Nd3+ (core), LaF3 :Nd3+@LaF3 (core/shell) and LaF3 :Nd3+@LaF3@SiO2
(core/shell/SiO2) nanoparticles (NPs) were designed and synthesized at low
temperature. The structure and morphology of the as-prepared nanoproducts
were characterized by X-ray diffraction and transmission electron microscopy
(TEM) techniques. Thermal analysis and FTIR spectral studies were conducted
to examine the surface properties of the nanomaterials. The as-prepared LaF3
:Nd3+ NPs exhibited hexagonal structure and were composed of monodispersed
irregularly and spherically shaped NPs with average grain size of 21 nm. TEM
image showed the successful silica surface coating, which was verified by
FTIR spectral analysis. The emission spectra of LaF3 :Nd3+ NPs was obtained
by monitoring the emission of Nd3+ at 325 nm (Cd laser) where it exhibited
the characteristic 4f?4f transitions lines originating from the Nd 4f3
configuration. Under UV light irradiation, the emission spectra revealed
various strong emission transitions which were greatly affected by the
surrounding silica surface coating. These observed results suggested future
applications in biolabeling and light-emitting diode.

Introduction/Objective. Strict gluten-free diet for life is the only treatment for patients with coeliac disease. Limited selection of food options can affect their quality of life and cause problems in acceptance by their peers. The aim was to examine the subjective quality of life experience in children and adolescents with coeliac disease and to obtain a comprehensive representation of physical and mental impairments and social functioning compared to their healthy peers. Methods. The study was conducted as a cross-sectional study. It included 116 respondents aged 5?18 years with coeliac disease and 116 healthy children of similar age and sex. A Serbian version of Pediatric Quality of Life Inventory (PedsQL) was used to measure the quality of life in children. Descriptive statistics were calculated to analyze all results, while t-test was used to compare them. Results. The mean value of total PedsQL score was lower in the coeliac disease patients (75.89 ? 20.35) than in the controls (86.35 ? 11.13). Additionally, the experimental group reported lower all PedsQL Scale scores than the control group in the domains of psychosocial, school, social, and emotional functioning. However, there was no statistically significant difference on the physical health scale. These results were the same in all age groups among both males and females. Conclusions. The disturbance of health-related quality of life in children and adolescents with coeliac disease is significant and the quality of life is lower if compared to their healthy peers.

Introduction/Objective. An important moment in oral health care and preventive dentistry is the first dental visit, recommended to be undertaken between the child?s sixth and 12th month of life. Worldwide evidence shows a considerable delay. This study evaluates characteristics of the first dental visit in a public health care center in Novi Sad, Serbia, during 2006?2015 period, and changes in occurrence driven by the healthcare reform. Methods. The study design was retrospective, evaluating available data on age and the main reason for the first dental visit of 270 children, who come to the same dentist and pediatrician in a public health care center during the 2006?2015 period. Results. Collected data determined the third and the fourth year of life as the dominant age (45.8% of children) for the first dental visit in 2006?2010, initiated mostly by a dental check-up (53.8%). During the second period (2011?2015), most of the first visits (31.1%) were done by the age of one, while the main reason for 80.1% of the visits was dental check-up. Conclusion. Considerable progress regarding the first dental visit was made in the observed period, which is, at least partially, due to the health care reform and emphasized preventive versus curative measures, by means of advanced communication between parents and chosen medical staff in prenatal and pediatric clinics.
Steel Cord–Rubber Adhesion with SEM/EDX
Authors: Chen Yusheng , Schlarb Jeremy L.
Published: April 2018

Brass-coated steel cords are widely used as reinforcement material for rubber composites. The adhesion between steel cord and rubber is critical throughout the lifetime use of steel cord/rubber composites; thus, the adhesion mechanism has been a focus of the rubber industry for several decades. Various modern analytical instruments, such as X-ray spectroscopy and mass spectroscopy, have been applied to the study of this bonding interface. In this paper, scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX) was used to research the morphology of the steel cord surface and the adhesion mechanism. According to these morphology testing results, the rubber residue bands were observed be orientated and located mostly in Cu/Zn void areas. Further research reveals that macro-structure adhesion layer leads to interlocking mechanism for rubber residue.

Due  to  the stochastic  nature  of  wind,  the  wind power integration into the power system poses serious challenges to  the transmissionsystem  operators(TSO).  The  impact  of large amounts  of windenergygeneration onto  the  power  system  may congest  some  of  the transmissionlines  that  transport  it  to  the (sometimes)distant consumption centres. Since the occurrence of wind not  only  contributes  to  the  loading  of theconnecting electric  line,  but also  increases  the  line  capacity,  via  convective cooling  of  the  cables,  a dynamic line rating  (DLR)analysis computes a more realistic set of values for the line capacity,thusit can be a cost-effective solution toalleviatesomeoverhead line congestion problems.This work presentsan  operational  tool  for  the  DLR  analysis  of power networks,allowingthe optimal  integration  of  renewable energy sources,especially wherepotentially congested linesmay exist.  The  tool  was appliedto  a  real  case  studyusing  forecast meteorological  data,  and the results achieved were  compared with  those  obtained  by using the  Portuguese TSOmethodfor assessingthe  transmission  capacity  of  the  lines. For  high  wind speed   conditions,results  show anoticeable  increase   on  the cable’s convective cooling assessed by the DLR analysis. This assessmentleadsto a noticeable rise on the cables’capacitiesthat overcame the congestion associated with the high injection levels of wind power generationin the power grid.

This paper studies the feasibility of using small electrical machines (e.g. automotive alternator, induction motors of domestic applications or electrical motors of some industrial application) as low cost generators for small wind turbine or small hydro power; its transformation in generators is not difficult. The objective is to provide a comparison among permanent magnet synchronous generator PMSG with different topologies (rotor configurations). The analysis was performed using FEMM-2D simulation software, which is based on finite element method. Small wind and hydro power systems are very attractive to support the energy demand for rural areas or developing countries where the electrical microgrid infrastructure is limited. Claw-pole automotive alternators can provide low cost alternative to permanent magnet synchronous generators for small wind and hydro turbines applications. The objective is the integration of hybrid energy conversion systems in microgrids and the development of small stand-alone systems in rural environment.

To improve light absorption in the visible region and to improve photoelectrochemical (PEC) response; herein, we have presented the doping of titanium dioxide (TiO2) nanotubes with nitrogen. TiO2 nanotubes have been heat treated under the ammonia environment at different temperatures for 3 h. The characterization was carried out using field emission gun scanning electron microscopy, (FEG-SEM), visible ultraviolet (UV-Vis) spectrophotometry. The photoelectrochemical tests of the samples were carried out in a Na2S/Na2SO3 (aq) solution. It was found that the nitrogen doping of titanium dioxide in temperature above 600 °C collapses the tubular structure and decreases the PEC performance. On the other hand, PEC performance improving was obtained from the sample nitrided at the lower temperatura which is related to the formation of lower defects in the structure of TiO2 nanotubes.
Massive ribs fractures due to artriohepatic dysplasia (Alagille syndrome): a case report.
Authors: Aboud Mohammed J
Published: April 2018

Abstract   Alagille syndrome (ALGS) is a rare multisystem congenital disorder, with a minimum incidence of approximately 1:30,000 live births. It is an autosomal dominant disease that arises from mutations in the Jagged1 (JAG1) gene (approximately 60% of cases are caused by de novo mutations), which encodes a ligand for Notch receptors. The most common symptoms associated with this syndrome are cholestasis with the obstruction or slowing of biliary flow, congenital heart disease (pulmonary artery stenosis), and butterfly-shaped vertebrae, anterior chamber eye defects, and dysmorphic faces. Several of the characteristics of Alagille syndrome may result in patients having an especially high risk of fracture. The majority of patients suffer from chronic cholestasis, which can have a variety of adverse effects on bone metabolism. Case presentation; A 6-months-old girl admitted to pediatric surgery unit with jaundice since one month of age, progressive abdominal distention. She had been diagnosed with biliary atresia at the age of 1 month on the base of clinical diagnosis, she was malnourished with stunted growth. She had most of the features of Alagille syndrome. Chest radiographs showed generalized decreased in bone density with multiple ribs fractures on the left side, with pulmonary consolidation in the left middle and lower zone. Osteodystrophy (haptic cause) was enrolled based on the fact that there was no evidence or history of trauma (child abuse by the family was not considered). Our study is one of a few reports to document ribs fracture in children with AGLS.

Background: Although the presence of Epstein-Barr virus (EBV) in different T-cell malignancies has been widely reported, there is very few data available for EBV infection of normal T cells. This leads to the lack of knowledge on the early events after T cell infection. Objective: Investigate the early events occurring after normal human peripheral T-cells are infected with EBV in vitro. Methods: T-cells were treated with EBV in vitro. The expression of tumor necrosis factor- α (TNF-α) mRNA were determined using reverse-transcription (RT)-PCR, and the level of TNF-α and interferon- γ (IFN-γ) in the culture supernatant were measured using ELISA. The effect of virus inactivation on cytokine induction from T-cells was also determined. Results: At the beginning of T cell infection by EBV, the expression of several lytic EBV transcripts (BALF5, BcLF1, and BLLF1) were observed using RT-PCR. This indicated the susceptibility of in vitro EBV infection and the entering lytic cycle of EBV-infected T-cells. The interactions of EBV with T-cells lead to induction of inflammatory cytokines, tumour necrosis factor- α (TNF-α) and interferon- γ (IFN-γ), production from the T-cells. Inactivation of the virus by UV irradiation eliminated the TNF-α and IFN-γ induction by EBV, suggesting the involvement in the expression of viral gene(s). Conclusion: This in vitro analysis demonstrated the cytokine induction by EBV after primary infection of T-cells.

Background: Indinavir, one component in the HAART regimen, plays an important role in the current treatment of HIV-infection and AIDS. Availability and accessibility of qualified generic indinavir to patients may be the keys for the success of treatment. Objective: Compare the rate and extent of absorption of a generic indinavir formulation with those of an original formulation in healthy Thai volunteers. Method: A randomized, two-period, two-treatment, two-sequence, crossover study with a two-week washout period was performed. A single dose of 2×400 mg indinavir capsules of each formulation was administered to 24 volunteers after an overnight fast. Indinavir plasma concentrations up to 10 hours postdose were determined using high-performance liquid chromatography. Relevant pharmacokinetic parameters were derived and tested for statistically significant differences using ANOVA and criteria of bioequivalence determination were applied. Results: No statistically significant differences were demonstrated for pharmacokinetic parameters including Cmax, Tmax, AUC0-t, and AUC0-∞ derived from the two formulations (n=23, p>0.05). The criteria of bioequivalence determination i.e., the 90% confidence intervals on the mean ratio (generic/original formulation) of natural logarithmtransformed values of Cmax, AUC0-t and AUC0-∞ were 86.3-106.5%, 94.0-108.5%, and 93.9-108.5%, respectively. Conclusion: As the mean ratios of Cmax, AUC0-t and AUC0-∞ of the generic and original formulations were entirely within the guideline range of bioequivalence (80.0-125.0%), the two formulations were considered bioequivalent in terms of rate and extent of absorption.
