Published: October 2019

Teachers have an important role in educating students well. One way that teachers can do to be able to increase motivation and school engagement is by providing social support to students. This study aims to find out the overview of perceived social support from teachers by high school “X” students in South Tangerang. The research method is descriptive qualitative research with data collection techniques through focus group discussions and structured interviews. The results of data retrieval show that the perceived social support from some teachers by high school "X" students is quite satisfying for students but not from every teachers. This means it can still be improved again. This is because not all teachers are considered good enough at providing social support to students. The total number of teachers are 17 people and for students are 67. It should be able to be improved in communication skills so that they can provide better social support to students.
Keywords : Adolescent, School, Social support.

Abstract
B ackground : This study aimed to explore whether autophagy can attenuate postoperative cognitive dysfunction (POCD) by up-regulating cystatin C (CysC) in aged rats undergoing splenectomy.
Methods : Rats were randomized into four groups ( n = 10 per group): normal control (CON), surgery (SUR), surgery + rapamycin (autophagy inducer) at 1.0 mg/kg/d (RAP), and surgery + 3-methyladenine (autophagy inhibitor) at 3.0 mg/kg/d (3-MA). Treatments were carried out for four weeks. Postoperative learning and memory were assessed using the Morris water maze. Hippocampal expression of the autophagy-related proteins ATG5, LC-3B, Beclin1, and p62 as well as Cys C was assayed using Western blotting and real-time polymerase chain reaction.
Results: SUR animals showed higher levels of autophagy and higher expression of autophagy proteins and Cys C than CON animals. These levels were even higher in RAP animals, which also showed lower levels of the inflammatory factors IL-1β, IL-6 and TNF-α than the other groups. Learning and memory functions were higher in RAP animals than in the other groups on days 5 and 7. Effects of 3-MA were opposite to those of RAP.
Conclusion : Autophagy improves learning and memory in aged rats following splenectomy, which may involve up-regulation of Cys C and attenuation of neuro-inflammation.

Abstract
Background: Deoxynivalenol (DON) is a common trichothecene mycotoxin found throughout the world. DON has broad toxicity in animals and humans. Its neurotoxicity in vitro, however, is still unclear. This study was designed to investigate the hypothesis that DON toxicity in neurons occurs via the mitochondrial apoptotic pathway. Results: Using piglet hippocampal nerve cells (PHNCs), we evaluated the effects of varying concentrations of DON on typical indicators of apoptosis. The results obtained demonstrated that DON treatment inhibited PHNC proliferation and led to morphological, biochemical, and transcriptional changes consistent with apoptosis, including decreased mitochondrial membrane potential, mitochondrial release of CYCS and AIF, and increased abundance of active cleaved-caspase-9 and cleaved-caspase-3. Increasing concentrations of DON led to decreased Bcl-2 expression and increased expression of Bax and Bid, which in turn increased transcriptional activity of the transcription factors AIF and P53. Addition of a caspase-8 inhibitor abrogated these effects. Conclusion: These data reveal that DON induces apoptosis in PHNCs via the mitochondrial apoptosis pathway, and that caspase-8 plays an important role during apoptosis regulation.

Abstract
Background The purpose of this study was to determine the difference in peripapillary retinal nerve fiber layer (RNFL) thickness in patients with preperimetric glaucoma and open angle glaucoma (POAG) in comparison to healthy population, as well as to determine the difference in thickness of peripapillary RNFL according to progression of the disease.Methods In this study, 120 patients were included . On the basis of clinical finding four groups of patients were formed: group without glaucoma, early POAG group, moderate POAG group and group with preperimetric glaucoma. Complete ophthalmological examination, visual field and optic coherent tomography of peripapillar region of RNFL were performed. The collected data was entered into a specially created database on a personal account, and the statistical processing was done using the SPSS for Windows. Results are displayed through charts and tables.Results The results showed that the thickness of peripapillary RNFL in patients with mild POAG is lesser than in healthy subjects, and thickness in patients with moderate POAG is lesser than in patients with mild POAG, as well as in healthy subjects (59.69±10.63 μm vs 73.44±12.16 μm vs 105.57±11.34 μm). Thickness of peripapillary RNFL in patients with preperimetric glaucoma is significantly lesser than in healthy subjects (83.65±9.24 μm vs 105.57±11. 34 μm). Parameter S together with mean value of peripapillary RNFL thickness (AvgThic) is the best predictors of appearance and progression of preperimetric glaucoma. There is positive correlation between progression of glaucoma (MD value) and AvgThic. The best predictors of appearance and progression of glaucomatous disease are: AvgThic, RNFL thickness in quadrants- S, I, N; and parameters RNFL- Smax, Savg, Iavg. ROC curve has shown that the following parameters are bad markers for progression of the disease: RNFL thickness in quadrant T and Imax.Conclusions We concluded that the determination of thickness of peripapillary RNFL in patients with glaucoma using optical coherent tomography represents the method which distinguishes between patients with POAG, preperimetric glaucoma and healthy population hence it can be used in glaucoma diagnostics and follow-up.

Published: October 2019

Introduction :
The typical factors precipitating diabetic ketoacidosis (DKA) include infections
(30%), cessation of antidiabetic medication (20%), and a new diagnosis of diabetes (25%). The
etiology remains unknown in 25% of cases. Less frequent causes cited in the literature include severe
thyrotoxicosis and, infrequently, pericarditis. Few publications have described the role of human T
lymphotropic virus type 1 (HTLV-1) in endocrine and metabolic disorders. Based on a clinical case associated
with several endocrine and metabolic disorders, we suggest a potential role for HTLV-1, an
endemic virus in the Amazonian area, and review the literature concerning the role of this virus in thyroiditis,
pericarditis and diabetes mellitus.

Case Report :
A fifty-year-old Surinamese woman without any medical history was admitted for diabetic
ketoacidosis. No specific anti-pancreatic autoimmunity was observed, and the C-peptide level was
low, indicating atypical type-1 diabetes mellitus. DKA was associated with thyrotoxicosis in the context
of thyroiditis and complicated by nonbacterial pericarditis and a Staphylococcus aureus subcutaneous
abscess. The patient was infected with HTLV-1.

Conclusion:
To our knowledge, this uncommon association is described for the first time. Few studies
have analyzed the implications of HTLV-1 infection in thyroiditis and diabetes mellitus. We did not
find any reports describing the association of pericarditis with HTLV-1 infection. Additional studies
are necessary to understand the role of HTLV-1 in endocrine and cardiac disorders.

O incremento do setor sucroenergético no estado de Mato Grosso do Sul esteve inicialmente ligado ao projeto do ProÁlcool, esse subsidiava as agroindústrias para produção do álcool combustível- etanol. No período de 1979 a 1990 haviam apenas 9 usinas no estado e após o ano de 2015 o setor contava com 25 unidades. A produção e a área de cultivo da cana-de-açúcar quadruplicaram no período de 2003 a 2015. O presente estudo tem como objetivo mapear o uso e cobertura das terras e a evolução temporo-espacial da cana-de-açúcar na bacia hidrográfica do Rio Brilhante, uma importante bacia hidrográfica localizada na região centro-sul de Mato Grosso do Sul, Brasil. Para tanto utilizou-se de técnicas e de ferramentas de sensoriamento remoto associadas à trabalhos de campo, isso a fim de validar os resultados e identificar o uso e a ocupação das terras. Alerta-se sobre o uso e a ocupação exclusiva das terras com a melhor aptidão agrícola pela cana-de-açúcar, isso, no futuro, possivelmente suscitará danos às economias locais, e, no médio prazo, ao país vide a escolha por um padrão no qual a monocultura é prioritária.

Published: October 2019

A pesca artesanal tem como característica principal o uso da mão de obra familiar, embarcações de pequeno porte e apetrechos tradicionais e rudimentares para a captura de peixes. Objetivou-se investigar o conhecimento etnoictiológico dos pescadores artesanais da colônia de pescadores Z-9 residentes no município de Castelo do Piauí, Piauí. Levantou-se dados qualitativos e quantitativos com 55 informantes, por meio de entrevista semiestruturada. Os dados foram compilados e analisados utilizando os programas estatísticos Excel, BioEstat 5.0 e EstimateS Win 9.10. Para análise dos dados calcularam-se o Valor de Uso (VU), Fator de Consenso dos Informantes (FCI), Importância Relativa (IR), além de índices de diversidade, tais como Shannon-Wiener, Simpson e rarefação. Registrou-se 49 espécies, 33 gêneros e 20 famílias de peixes, distribuídas em três categorias de uso: alimentícia, comercial e medicinal. <em>Prochilodus lacustris </em>Steindaches, 1907 (crumatá) apresentou maior valor de uso geral e potencial (VU geral = 2,02; VU potencial = 1,85), seguida das espécies <em>Leporinus friderici </em>Bloch, 1974 (piau-de-coco) e <em>Schizodon dissimilis </em>Garman, 1890 (piau-de-vara), ambas com VU geral = 1,78 e VU atual= 1,75. Dentre as doenças citadas, a categoria com maior valor de Fator de Consenso dos informantes (FCI) foi a de Lesões, envenenamentos e algumas outras consequências de causas externas (FCI=1), seguida de doenças do aparelho respiratório (FCI=0,93). De acordo com o índice de importância relativa (IR), as espécies mais versáteis foram <em>Potamotrygon signata </em>Garman, 1913 (arraia, IR = 2,00), seguida de <em>Hoplias </em>aff<em>. malabaricus </em>Bloch, 1794 (traíra, IR = 1,82) e <em>P. lacustris </em>(crumatá, IR = 1,39). A atividade pesqueira no município de Castelo do Piauí é realizada no rio Poti, os pontos de pesca citados foram: Poço Amarelo, rio Cais, Cânion do Poti e Mesa de Pedra, e a distância percorrida para a pesca pode ser superior a 60 km. Foram registrados seis tipos de apetrechos de pesca: anzol de linha, anzol de vara, engancho, groseira, rede de emalhe e tarrafa. Algumas espécies, tais como <em>P. lacustris</em>, foram citadas como “reimosas”<em>.</em> Deste modo, pode-se dizer que os pescadores artesanais são detentores de conhecimento empírico da atividade pesqueira.

Manejo das Hemorragias Relacionadas aos Anticoagulantes Orais de Ação Direta
Authors: Ramos Ali Ganem Isabela , Behrmann Martins Luiz Claudio , Mendonça Tomé Carlos Eduardo 
Published: October 2019

Introdução: Os anticoagulantes orais diretos (direct oral anticoagulant – DOACs) são uma nova classe de anticoagulantes que inibem diretamente a trombina (dabigatrana) ou o fator Xa (rivaroxabana, edoxabana e apixabana) na cascata da coagulação. Esses estão sendo cada vez mais utilizados para tratamento e prevenção de eventos tromboembólicos, principalmente em pacientes com fibrilação atrial, em substituição à varfarina ou outros antagonistas de vitamina K (AVKs). Embora a incidência de hemorragias seja maior nos AVKs do que nos DOACs, elas também podem ocorrer nesse grupo, até mesmo na forma de hemorragia intracraniana (HIC) com risco de morte. Atualmente as indicações dos DOACs vêm aumentando progressivamente, e a disponibilização de seus agentes reversores específicos certamente aumentará a segurança e, consequentemente, sua utilização. O idarucizumab, reversor da dabigatrana, e o andexanet alfa, reversor dos inibidores do fator Xa, foram aprovados pelo Food and Drug Administration (FDA) dos Estados Unidos e o ciraparantag poderá ser aprovado em um futuro próximo. Objetivo: Revisar a literatura sobre o manejo da hemorragia relacionada ao uso dos DOACs. Métodos: Revisão da literatura que utilizou artigos de 1998 a 2017, de diversas plataformas e revistas. Conclusão: Os DOACs constituem um grande avanço na profilaxia e tratamento da doença tromboembólica, que cursa com elevada morbimortalidade, e as hemorragias são os principais eventos adversos relacionados ao seu uso, sendo raramente necessária a reversão imediata da anticoagulação. No entanto, a existência dos reversores específicos dos DOAcs aumenta a segurança dos pacientes, que poderão ter sua anticoagulação revertida rapidamente, se necessário.

The objective of the present work is to find out the viable substitute fuel for diesel and control of pollutants from compression ignition engines. Therefore, in this present investigation an attempt has been made to study the effect of 20% proportion of five different biodiesel diesel blend in diesel engine. The 20% proportion of biodiesel such as Jatropha, Pongamia, Mahua, Annona and Nerium and 80% of diesel and it is denoted as J20, P20, M20, A20 and N20 are used in the present investigation. The experimental results showed that the brake thermal efficiency of the different biodiesel blend is slightly lower when compared to neat diesel fuel. However, N20 blend, have shown improvement in performance and reduction in exhaust emissions than that of other biodiesel diesel blends. From, the experimental work, it is found that biodiesel can be used up to 20% and 80% of diesel engine without any major modification.
The conducted experiments were conducted on a four cylinder four stroke DI and turbo charged diesel engine using biodiesel blends of waste oil, rapeseed oil, and corn oil with normal diesel. The peak cylinder pressure of the engine running with bio diesel was slightly higher than that of diesel. The experiments were conducted on a four cylinder four stroke diesel engine using bio diesel made from corn oil.
