Published: October 2016

<p>Tebu (Saccharum officinarum L.) merupakan tanaman yang diperbanyak secara vegetatif sehingga berisiko besar akan terjadinya akumulasi virus di dalam jaringan tanaman. Kultur meristem merupakan salah satu teknik eliminasi virus yang umum digunakan, namun seringkali meristem memiliki daya hidup dan daya re-generasi yang rendah. Salah satu penyebabnya adalah karena akumulasi senyawa fenol. Akumulasi senyawa tersebut dapat direduksi melalui penggunaan senyawa adsorben dan antioksidan. Penelitian ini bertujuan un-tuk mengetahui pengaruh polyvinylpyrrolidone (PVP) dan diethyldithiocarbamate sodium (DIECA) terhadap regenerasi meristem tebu. Bahan tanaman yang digunakan adalah tebu PS864. Eksplan yang digunakan adalah meristem dengan 1–2 primordia daun yang diisolasi di bawah mikroskop. Perlakuan meliputi PVP (100 dan 300 mg/l) dan DIECA (0 dan 20 mg/l) serta kombinasi antara kedua zat tersebut, dengan 3 ulang-an (botol) dan setiap botol terdiri atas 3 meristem. Hasil penelitian menunjukkan bahwa peningkatan kon-sentrasi PVP atau kombinasi perlakuan PVP dan DIECA dapat meningkatkan persentase eksplan hidup, daya regenerasi, dan jumlah tunas. Kombinasi perlakuan PVP 300 mg/l dan DIECA 20 mg/l merupakan perlakuan terbaik karena persentase hidup dan daya regenerasi eksplan yang paling tinggi (100%) dengan jumlah tu-nas 3,8 tunas/eksplan.</p><p> </p><p>Being vegetatively propagated, sugar cane faces a high risk of virus accumulation. Meristem culture is one method that usually applied for virus elimination. However, it often has low survival and regeneration rate due to an accumulation of phenolic compounds. Accumulation of those compounds can be reduced by apply adsorbent antioxidant. This research aimed at evaluating the effect of PVP and DIECA on the regeneration capacity of meristem. The plant material was sugar cane PS864. Meristems with 1─2 primoridial leaves were used as the explants and isolated under microscope. The PVP (100−300 mg/l) and DIECA (0− 20 mg/l), or combined treatment of both antioxidants were used as treatments. Each treatment was replicated 3 times (bottles), and each bottle contained 3 meristems. The result showed that the higher concentration of PVP or combined treatment of PVP and DIECA could increase the percentage of survival, regeneration rate, and number of shoot. The combined treatment of 300 mg/l PVP, and 20 mg/l DIECA produced the highest level of survival rate (100%) which yielded 3.8 shoots/explants.</p>

Summary
The accelerating-rate calorimeter (ARC) is unique for its exceptional adiabaticity, its sensitivity, and its sample universality. Accelerating Rate Calorimetry is one of the screening tests used to determine the suitability for air-injection enhanced oil recovery (EOR). These tests show oil reactivity and exothermicity over a broad range of temperatures: low-temperature range (LTR), negative-temperature-gradient region (NTGR), and high-temperature range (HTR). An experimental and simulation study was carried out to expand understanding and interpretation of the data derived from high-pressure closed-ARC tests.
Athabasca bitumen was used for the experimental study in a closed ARC at 13.89 MPag (2000 psig) to identify the temperature ranges over which the oil reacts with oxygen in the injected air. Self-heat rate from accelerating-rate calorimetry and mass-loss rates from the differential thermogravimetric analysis show the influence of mass transfer of oxygen within bitumen in the LTR and HTR. A numerical model was developed to integrate the concept of mass transfer with a reaction-kinetic model. The model incorporates solubility of oxygen with partition equilibrium coefficient (K-value) as a medium to introduce oxygen into the bitumen layer, which later transfers throughout oil layer by diffusion. This model considers both low- and high-temperature oxidation (LTO and HTO), and thermal-cracking reactions, as described in traditional reaction-kinetic models of in-situ-combustion (ISC) processes.
Results show that formation of an asphaltenes film in the LTR caused by oxidation of maltenes obstructs oxygen (mass-transfer restriction) penetration into the bitumen layer. The simulated result shows that, by integrating mass transfer with the kinetic model, it is possible to predict the NTGR. Viscosity and temperature dependence on the mass transfer of oxygen is linear. As time passes and chemical reaction becomes more important with increasing temperature, the relationship deviates from linearity. With increasing temperature, the influence of chemical interaction on the oxygen distribution becomes greater, and this results in a shorter initial stage of mass transfer of oxygen within the bitumen film at low temperatures. This implies that the ARC can be a useful tool for understanding the effect of mass transfer on the oxidation characteristic for predicting LTR, NTGR, and HTR.

Authors: Abu Shayeb Mohammad Kheare 
Published: October 2016

The experimental distributions for Heavy ion interaction, Au+Au, Pb+Au, Pb+Pb have been fitted to polynomial fit of 4th order to look at minor differences in multiplicity distributions for different targets at heavy ion collisions experiment. The multiplicity distributions found similar; except for small differences which may be of statistical in nature. This analysis supports the hypothesis that geometrical aspects play a dominant role in particle production in heavy ion interactions.

Published: October 2016

Background/Objective:
Lipopolysaccharides (LPS) promote allergic responses to nickel (Ni) both in the sensitization and elicitation steps. In this study, we examine the effect of pre-sensitization to LPS on the occurrence of Ni allergy using a mouse model.

Method:
A 100 mg of LPS was injected into C57BL/6J mice intraperitoneally (ip). Three weeks later, the mice were subsequently injected with 0.3 μ moles of nickel dichloride (NiCl2) and 100 μg of CpG-DNA, which acted as an adjuvant. The mice were repeatedly immunized with the 0.3 μg of nickel sulfate (NiSO4), along with 300 μl of the adjuvant, Inject Alum (Pierce, USA). Then we examined the producing capabilities of T helper type 1 (Th1) and 2 (Th2) cytokines (interferon-gamma- (IFN)-γ and interleukin (IL)-10, respectively) from anti CD3 antibody-stimulated spleen cells.

Results:
Pre-treatment with LPS, followed by repeated challenges with Ni2+ and adjuvants significantly enhanced the IFN-γ-producing capability of spleen cells (n=5, p<0.01); however, that could not enhance the capability of spleen cells by a single challenge with Ni2+ and adjuvants (n=5). In contrast, without LPS treatment, single or even repeated challenges by Ni2+ could not enhance the IFN-γ-producing capability. On the other hand, the IL-10-producing capability of spleen cells was not enhanced even by LPS and repeated challenges with Ni2+ and adjuvants.

Conclusion:
The solitary pre-sensitization to LPS is essential for the onset of Ni allergy by shifting the Th1/Th2 immune balance toward a Th1 dominant.

Published: October 2016

Objective:
To describe a patient with bilateral multifocal choroidal metastases from an endobronchial carcinoid treated with a somatostatin analogue.

Method:
A 60-year-old woman presenting with photopsia in the left eye underwent an extensive ophthalmic examination, including fluorescein angiography, OCT and ultrasound.

Results:
Fundoscopy revealed a small retinal tear in the left eye, for which she received laser treatment. In addition, choroidal masses were detected in both eyes. Her medical history of a pneumectomy for a bronchial carcinoid six years earlier together with recent elevated chromogranin A blood levels prompted a diagnosis of choroidal metastases. Subsequently, a Gallium-68 DOTANOC positron emitting tomography/computer tomography scan revealed a spinal cord metastasis and mediastinal as well as mesenterial lymph node invasion. Systemic treatment with Sandostatin®, a somatostatin analogue was started. Up until two years after the initial presentation and treatment, these choroidal lesions remained stable without any signs of growth.

Conclusion:
Endobronchial carcinoid tumors have an indolent nature and long-term follow-up is recommended for early detection of metastases. Although treatment with somatostatin analogues rarely induces complete tumor regression, tumor stabilization and prevention of symptoms related to hormone secretion is achieved. This well-tolerated systemic treatment provides a worthy alternative treatment for choroidal metastasis compared to classic radiotherapy without any risk of radiation or laser-related visual loss.
Lower Extremity Injuries in Young Floorball Players: A Prospective Study on Overuse Injuries
Authors: Beischer Susanne , Augustsson Sofia Ryman 
Published: October 2016

Background:
Overuse injuries in sports seem to be 1.5 to 2.5 times more common than traumatic injuries in the lower extremity (LE) in children and adolescents. Floorball is the most popular indoor sport in Sweden and is associated with many potential risks of injuries. However, to our knowledge, no previous studies have examined the appearance of injury in young floorball players.

Objective:
The aim of the present study was to investigate the occurrence of overuse injuries in LE in floorball players aged 15 or younger, with respect to frequency, location, and consequence of injury.

Method:
Fifty-seven players, from 9 different teams, participated (mean age 11±2 years). A modified version of Oslo Sports Trauma Research Center Overuse Injury Questionnaire was submitted every fourth week during five months in order to record overuse injuries in LE. An online survey software was used to send out the questionnaires.

Results:
A of 42 overuse injuries in 42% (24/57) of the cohort were found. The average monthly prevalence for all players, in any anatomical area, was 28% (95% confidence total interval 18%-38%). The most common location of injuries was the knee (43%), followed by the foot (40%).

Conclusion:
The present study shows, in accordance with other recent studies on children and adolescents that overuse injuries seem to be a common problem for young floorball players. Knee and foot appear to be the most common location for overuse injuries in this population. Prospective analyses of different mechanisms for overuse injury in youth athletes and the relation to growth-related overuse disorders is desirable.

Objetivos: Investigar possíveis relações entre DPP, condições da gravidez e parto e assistência prestada pelo sistema de saúde público e descrever as características sócio-demográficas de mulheres no período puerperal. Materiais e Métodos: Foram entrevistadas 198 puérperas atendidas no Sistema Único de Saúde (SUS) de uma cidade do Sul de Minas Gerais, com idades entre 14 e 46 anos. Após lerem e assinarem o Termo de Consentimento Livre e esclarecido, elas responderam um questionário sócio-demográfico, a Edimburg Postpartum Depression Scale (EPDS) e questões sobre condições da gravidez, parto e assistência prestada pelo SUS. Resultados: A prevalência de DPP foi de 17,2%. As variáveis idade entre 36 e 40 anos (p=0,03, RP=2,4), estado civil separada (p=0,04, RP=2,5), presença de distúrbios psíquicos em gestações anteriores (p< 0,001, RP=3,92), distúrbios psíquicos prévios durante a vida (p< 0,001, RP= 4,25), apresentaram associação com a ocorrência de depressão. Conclusões: O presente estudo apresenta resultados de elevada prevalência de DPP e sugere que pode ocorrer associação com fatores ligados à situação sócio-demográfica da mulher, assim como eventos da sua história médica pregressa. Além disso, nossa pesquisa traz à luz a aparente dificuldade dos profissionais de saúde da rede pública, na abordagem e tratamento de patologia tão prevalente, que leva ao sofrimento significativo para a mãe e potenciais de riscos para a mesma e o seu filho, mas que tem sido pouco reconhecida por esses profissionais.Palavras-chave: Depressão pós-parto, assistência, SUS

Treinamento de Força para Atletas de Elite em Provas de Endurance/Resistance Training for Elite Athletes in Endurance Events
Authors: Lopes Charles Ricardo , Sindorf Márcio Antônio Gonçalves , Mota Gustavo Ribeiro da , Cesar Marcelo de Castro 
Published: October 2016

O objetivo deste estudo foi revisar trabalhos que investigaram os efeitos do treinamento de força (TF) para o desempenho de endurance. Os principais fatores fisiológicos determinantes das provas de endurance (PE) são o consumo máximo de oxigênio (VO2max), o limiar anaeróbio (LAn) e a economia de movimento (EM). Ambos VO2max e LAn são bem estimulados com meios e métodos tradicionais de treinamento e essas duas variáveis parecem ser pouco sensíveis ao TF em pessoas treinadas. Por outro lado, a EM pode ser aperfeiçoada com o TF, mesmo em indivíduos bem treinados em endurance. Portanto, concluímos que o TF colabora para a melhora na endurance, por meio do incremento da EM, e esses resultados sugerem mudança de paradigma na periodização do treinamento de PE. Palavras chave: fundistas; treinamento de potência; exercícios com pesos; performance. The aim of this study was to review studies that analyzed the effects of resistance training (RT) on endurance performance. The main physiological determinants of endurance events is the maximal oxygen uptake (VO2max), anaerobic threshold (AT) and economy of movement (EM). Both, VO2max and AT, are very encouraged with the means and traditional methods of training and these two variables appear to be few sensitive to people already trained in RT. On the other hand, EM can be improved with the RT even in endurance-trained individuals. Therefore, we conclude that RT contributes to the improvement in endurance, through the increase in EM, and these results suggest a paradigm shift in periodization training of endurance events. Key words: distance runners; power training; resistance training; performance.

Objetivo: Avaliar os efeitos da suplementação de L-Arginina e L-Arginina associada ao maleato de enalapril na pressão arterial média (PAM) de ratos hipertensos. Materiais e Métodos: Quarenta e oito ratos machos, adultos, da linhagem Wistar foram utilizados, divididos em seis grupos (n=8), de acordo com o tratamento. Os animais foram submetidos a cirurgia para indução de hipertensão arterial pelo modelode Grollman modificado. Quinze dias após a cirurgia os ratos hipertensos (PAM > 140mmHg) receberam diariamente pelo método de gavagem diferentes tipos de tratamento, durante trinta dias. A PAM foi aferida duas vezes por semana, por pletsmografia de cauda. Ao final do período experimental os ratos foram anestesiados (Cetamina/Xilazina, I.P). Resultados: O tratamento com L-Arginina reduz significativamente a PAM a partir do terceiro dia quando comparada ao grupo Controle. Como esperado, o tratamento com maleato de enalapril 2,5 mg/Kg e 5,0 mg/Kg também reduziu significativamente a PAM a partir do sexto dia quando comparada ao grupo Controle. A associacão entre L-Arginina e maleato de enalapril 2,5mg/Kg reduziu significativamente a PAM quando comparada ao grupo Controle a partir do sexto dia e a partir do terceiro dia usando maleato de enalapril 5,0mg/Kg e se manteve durante todo o período experimental. Conclusão: Os dados indicam que o tratamento com L-Arginina associada ao maleato de enalapril 5,0mg/Kg reduz significativamente e mais rápido a PAM quando comparada aos outros grupos.

Published: October 2016

O Retinoblastoma é a neoplasia intraocular mais comum na infância. Por meio do teste do reflexo vermelho, também conhecido como “teste do olhinho”, é possível a detecção da leucocoria, principal sintoma do retinoblastoma. Este teste possibilita o diagnóstico precoce do câncer, com maiores chances de preservação da visão e maiores taxas de cura, minimizando o tratamento e maximizando a qualidade de vida. Nos países desenvolvidos, a maioria dos casos tem diagnóstico, enquanto intraocular. No Brasil, pela demora diagnóstica, a não realização do Teste do Reflexo Vermelho (TRV) como rotina, a desinformação dos pais e o maior tempo de encaminhamento, 40% dos pacientes são portadores de tumores extraoculares. A forma mais precoce de se detectar o retinoblastoma é através da incorporação do TRV na rotina dos pediatras em exames de recém-nascidos. Palavras chave: retinoblastoma, teste do reflexo vermelho, diagnóstico precoce, triagens visuais.
