Os implantes biomédicos surgiram para solucionar diversos problemas na área da saúde, principalmente na reabilitação de pacientes, através de Implantes Odontomédicos, melhorando a qualidade de vida. Na busca por superfícies de implantes que supram a necessidade de obter uma rápida osseointegração em áreas de baixa densidade óssea, inúmeras pesquisas têm sido desenvolvidas para modificar a morfologia superficial. Há vários processos que envolvem métodos mecânicos, químicos e físicos, objetivando os mais variados graus de texturas. Dentre eles existe a Oxidação por Plasma Eletrolítico (Plasma Eletrolytic Oxidation - PEO). Com o intuito de resolver o problema, foi utilizado o PEO como método de tratamento de superfícies. Tratou-se 18 cilindros de titânio grau II, com 3 mm de diâmetro e 25 mm de comprimento. O tempo de tratamento utilizado foi de 1, 8 e 16 minutos. A solução eletrolítica estava na temperatura ambiente e a tensão aplicada foi de 290 V. Após os tratamentos, as amostras foram caracterizadas por Fluorescência de Raios-X (FRX), Microscopia Ótica (MO), Microscopia Eletrônica de Varredura (MEV) e por Espectroscopia de Raios-X e Energia Dispersiva (EDS). Em seguida foi feito Microscopia de Força Atômica (AFM) para caracterização da textura superficial. Realizou-se ainda a inspeção visual e ensaios de molhabilidade. Identificou-se neste trabalho através das análises químicas pela Fluorescência de Raios-X a presença do TiO2 na superfície da amostra. Verificou-se no MEV que os revestimentos exibem uma característica porosa, apresentando uma interface bem aderida e sem presença de espaços vazios. Nas imagens do AFM observou-se que com o aumento do tempo de tratamento houve uma maior rugosidade e aumento da homogeneidade da distribuição dos cristais cerâmicos na superfície. Nos ensaios de molhabilidade apresentaram um ângulo de molhamento menor para as amostras com o tratamento por PEO com tempo de 1 e 8 minutos. Conclui-se que a técnica por Oxidação por Plasma Eletrolítico mostrou-se eficaz na deposição de um revestimento cerâmico na superfície da liga de titânio.

Progress and Challenges of Implementing Decentralized HIV Testing For Prevention of Mother-to-Child Transmission of HIV – Myanmar
Authors: Hone San , Li Li , Lee Sung-Jae , Comulada W. Scott , Detels Roger 
Published: May 2019

Background: Myanmar has adopted point-of-care (POC) HIV testing for its prevention of mother-to-child transmission of HIV program, and was initiated in 84 townships in 2013. This study assessed the progress of HIV testing uptake from 2012, one year prior to POC testing, to 2015, and the challenges faced by service providers during the rapid rollout of this testing strategy.
Methods: This serial cross-sectional study included 23 townships randomly selected from the 84 townships. An open-question survey was used to collect information on the challenges faced by service providers. A random effects logistic model was used for assessing the progress of HIV testing uptake among urban and rural health center groups.
Results: HIV testing uptake for antenatal care (ANC) attendees increased from 60% to 90% for rural and from 70% to 90% for urban attendees. The proportion of ANC attendees who were tested at their first visit increased from 70% to 80% for rural and from 70% to 90% for urban attendees. In addition, the proportion receiving same-day test results increased from less than 10% to 90% for both groups. Major challenges faced during the initial rollout included low health awareness among pregnant women, fear of stigma and discrimination, long travel times and costs, and increased workloads of providers in rural settings.
Conclusions and Global Health Implications: The program should consider recruiting local volunteers to help reduce the workloads of service providers. Professional education based on need and continued mentoring and quality control schemes for HIV testing need to be in place. This decentralized strategy would be applicable to other resource-limited countries.

Abstract
Background: To investigate the characteristics and distribution of anterior and posterior surface wavefront aberrations in patients suitable for corneal refractive surgery. Methods: A total of 121 myopic patients (121 eyes, 14-46 years old) who underwent corneal refractive surgery were randomly selected by the Pentacam anterior segment analysis system with a spherical equivalent (SE) of -1.50 to -12.00 D. The corneal anterior and posterior aberrations (higher-order aberration, HOA; spherical aberration, SA; Coma; Trefoil) and Q and K values were detected, and a correlation analysis of the relevant parameters was carried out. Results: The root-mean-square (RMS) of the third to sixth order aberrations of the ocular and corneal wave surface aberrations at a 6.0-mm pupil showed a decreasing trend in patients suitable for the corneal refractive surgery, and the RMS of the third order aberrations accounted for 62.92% of the total HOAs. The coma ratio (coma ratio: coma/total cornea higher-order aberrations) was increased with the increasing diopters, while the spherical aberration ratio (spherical aberration/ total cornea higher-order aberrations) was not changed. In addition, the spherical aberration was 0.203± 0.082 μm (range: 0.061 to 0.503 μm), and the Q30 was -0.19±0.03 (range: -0.58 to 0.31). There were significant differences in the coma aberrations of preoperative corneal anterior surface (3, 1) between the low, middle and high myopia groups (P=0.013). The spherical equivalent was positively correlated with the corneal coma of the preoperative anterior corneal surfaces (R=-0.241, P=0.009), and the Q value was positively correlated with the total higher-order aberrations (R=0.326, P<0.001). Conclusions: Individual wavefront aberrations on the anterior and posterior surfaces of the cornea are comparatively different, and the Zernike coefficients are related to the degree of myopia. Spherical aberrations are the most overriding aberrations of the cornea.
Transcriptome-wide single nucleotide polymorphisms related to electric organ discharge differentiation among African weakly electric fish (genus Campylomormyrus)
Authors: Canitz Julia , Kirschbaum Frank , Tiedemann Ralph 
Published: May 2019

Abstract
Background: African weakly electric fish generate weakly electric organ discharges (EODs) for orientation and communication. In the mormyrid genus Campylomormyrus, waveform and duration of discharges are species-specific and elongated pulses (> 4ms) are a derived trait. Pulse duration is presumed to depend on electrocyte geometry/excitability or hormonal signaling.Tissue-specific transcriptome analyses across species with different pulse durations have revealed differential expression of genes related to electrocyte excitability. There are also point mutations in ion channel genes which relate to pulse duration. However, a comprehensive assessment of expressed Single Nucleotide Polymorphisms (SNPs) throughout the entire transcriptomes of African weakly electric fish, with the potential to identify further genes influencing EOD duration, is still lacking. This is of particular value, as discharge duration is likely based on multiple cellular mechanisms and various genes. Here, we want to identify non-synonymous SNPs in transcriptomes of Campylomormyrus species differing by EOD duration.

Results: We identified 27 candidate genes with inferred positive selection among Campylomormyrus species and at least one non-synonymous substitution specific to Campylomormyrus tshokwe, a species with elongated EODs. Inferred candidate genes had mainly functions linked to transcriptional regulation, cell proliferation, cell differentiation and apoptosis. Further, we identified 27 GO terms and 2 KEGG categories ('Transcription' and 'Cancer: Specific types') for which C. tshokwe (derived elongated EOD) significantly more frequently exhibited a species-specific expressed substitution than C. compressirostris (ancestral short EOD).

Conclusion: We performed the first transcriptome-wide SNP analysis among weakly electric fish species (genus Campylomormyrus) and provide putative candidate genes and cellular mechanisms potentially involved in the determination of an elongated discharge in C. tshokwe. Most likely, transcriptional regulation as well cell proliferation, cell differentiation and apoptosis take part in the determination of pulse durations. The processes of cell growth and density are pivotal for tissue morphogenesis and might determine the shape of electric organs. This supports the observed correlation between cell geometry/tissue structure of the electric organ and discharge duration. The inferred expressed SNPs putatively related to EOD duration are a valuable resource for future investigations on this peculiar trait, which may focus on their functional implications.
