Published: December 2020

Sebagai Trader haruslah memiliki strategi trading yang menghasilkan capital gain/loss dari actual return. Overnight return dan intraday return merupakan bagian dari actual return. Namun actual return tersebut ternyata dipengaruhi oleh faktor lain. Faktor yang mempengaruhinya adalah fenomena anomaly Monday effect. Teori yang mendasari dari terbentuknya penelitian ini adalah Random Walk, Efficient Market Hypothesis, Anomalies. Random Walk menjelaskan mengenai pergerakan harga saham yang secara acak dan tidak adapat diprediksi sehinga return yang dihasilkan acak dan tidak dapat diprediksi. Efficient Market Hypothesis menjelaskan mengenai bagaimana informasi suatu sekuritas atau saham diguakan untuk memprediksi harga sekuritas atau saham di masa depan sehinga return yang dihasilkan dapat diprediksi. Anomalies menjelaskan mengenai fenomena yang menyimpang dari teori Efficient Market Hypothesis.

A adoção do plantio mecanizado da cana-de-açúcar causou o aumento do número de falhas no plantio, o que acarretou prejuízos na produtividade. Devido a isso, o Programa Cana, do Instituto Agronômico de Campinas (IAC) desenvolveu o sistema de mudas pré-brotadas (MPB) com o objetivo de diminuir o volume de mudas e falhas, além de permitir maior controle na qualidade, tanto para controle de pragas e doenças quanto para uniformidade do canavial. No entanto, a capacidade de desenvolvimento da gema e do sistema radicular do minirrebolo é variável com a variedade. Dessa forma, o uso de reguladores vegetais pode induzir o desenvolvimento do minirrebolo, como o ácido giberélico, que influencia, principalmente, no alongamento da parte aérea e o ácido indolbutírico, que é apontado como um dos maiores estimuladores de enraizamento. Desta forma, objetivou-se verificar o uso do ácido indolbutírico e do ácido giberélico associados a tempos de imersão como estimulante de brotação e enraizamento em muda pré-brotada (MPB) de cana-de-açúcar. O delineamento experimental utilizado foi inteiramente casualizado, com quatro repetições em esquema fatorial 5 x 3 [doses de AIB (500, 1000 mg L-1), doses de GA (60 mg L-1) e doses associadas de AIB e GA (500 + 60 e 1000 + 60 mg L-1) e tempos de imersão (60, 120, 180 segundos)], num total de quinze tratamentos + testemunha – imersa em água destilada. A porcentagem de brotação e massa seca da parte aérea de minirrebolos de cana-de-açúcar apresentaram resultados inferiores quando comparados a testemunha. Para altura de planta, massa verde da parte aérea, massa seca da parte aérea e massa seca da raiz, a dose de 1000 mg L-1 apresentou melhores resultados em ambos. Para os parâmetros altura de planta, massa verde da parte aérea, massa seca da parte aérea e massa seca da raiz, a dose de 500 mg L-1 foi inferior estatisticamente às demais. O uso dos reguladores de crescimento ácido indolbutírico e ácido giberélico associados aos tempos de imersão não influenciaram positivamente no crescimento dos minirrebolos de cana-de-açúcar em relação à testemunha.

A agricultura familiar corresponde à produção agropecuária realizada por pequenos produtores em que o sistema agropecuário é mantido pelo núcleo familiar e, no máximo, por alguns poucos funcionários assalariado, é um segmento coletivo em que se relacionam os fatores físicos, sociais, culturais e econômicos. A agricultura familiar é constituída por pequenos e médios produtores que representam a maioria de produtores rurais no Brasil. Nos últimos anos o segmento tem sido responsável por boa parte da produção de alimentos básicos, contribuem desta forma com o abastecimento urbano, por meio da diversificação de suas atividades e do beneficiamento dos alimentos e matérias-primas. objetivou-se com esse trabalho compreender como ocorre a assistência técnica na agricultura familiar e são as práticas de cultivo de hortaliças na região de Goianésia-Go, com isso avaliou-se quais são as hortaliças mais plantadas, método de irrigação utilizado, quais insumos são mais utilizados, como é realizado o meio de transporte dos produtos, onde são comercializados, se os produtores recebem assistência técnica para a produção de hortaliças, e qual a forma de cultivo utilizada, na região de Goianésia-GO. Realizou-se uma coleta de dados, através de um formulário semiestruturado, e os resultados foram expressos em gráficos para melhor apresentação e geração de gráficos estatístico. Constatou-se que 80% dos produtores não recebem assistência técnica, e cometem muitos erros no cultivo das hortaliças, e afirmam que uma assistência técnica permanente, irá contribuir muito para o aumento de produção e qualidade no produto final.
Altered Innate-like T Cell Development in Vα14-Jα18 TCRα Transgenic Mice

Abstract
CD1d-restricted invariant NKT (iNKT) cells are innate-like T cells that respond to glycolipids, a class of Ags that are invisible to conventional T cells. iNKT cells develop in the thymus where they receive strong “agonist” TCR signals. During their ontogeny, iNKT cells differentiate into discrete iNKT1, iNKT2, and iNKT17 effector subsets akin to helper CD4 T cells. In this study, we found that transgenic (Tg) expression of the canonical Vα14-Jα18 TCRα-chain at the double-positive thymocyte stage led to premature iNKT cell development and a cell-intrinsic bias toward iNKT2 cells, due to increased TCR signaling upon selection. Consistent with the strong iNKT2 bias, innate memory CD8+ T cells were found in greater numbers in Vα14 Tg mice, whereas the prevalence of mucosa-associated invariant T cells was reduced. iNKT cells from Vα14 Tg mice were hyporesponsive to stimulation by their cognate Ag α-galactosylceramide. Finally, Vα14 Tg mice displayed increased B16F10 melanoma tumor growth compared with wild-type mice. This study reveals some of the limitations of Vα14 Tg mice and warrants the cautious interpretation of past and future findings using this mouse model.

Abstract
Although fibrotic disorders are frequently assumed to be linked to TH2 cells, quantitative tissue interrogation studies have rarely been performed to establish this link and certainly many fibrotic diseases do not fall within the type 2/allergic disease spectrum. We have previously linked two human autoimmune fibrotic diseases, IgG4-related disease and systemic sclerosis, to the clonal expansion and lesional accumulation of CD4+CTLs. In both these diseases TH2 cell accumulation was found to be sparse. Fibrosing mediastinitis linked to Histoplasma capsulatum infection histologically resembles IgG4-related disease in terms of the inflammatory infiltrate and fibrosis, and it provides an example of a fibrotic disease of infectious origin in which the potentially profibrotic T cells may be induced and reactivated by fungal Ags. We show in this study that, in this human disease, CD4+CTLs accumulate in the blood, are clonally expanded, infiltrate into disease lesions, and can be reactivated in vitro by H. capsulatum Ags. TH2 cells are relatively sparse at lesional sites. These studies support a general role for CD4+CTLs in inflammatory fibrosis and suggest that fibrosing mediastinitis is an Ag-driven disease that may provide important mechanistic insights into the pathogenesis of idiopathic fibrotic diseases.

Published: December 2020

ABSTRACTWe report a 50-year-old Thai woman with recent travel to Denmark who presented with acute high-grade fever, vomiting, and myalgia for 1 day. Initial laboratory results revealed leukopenia, elevated aspartate transaminase, and elevated alanine transaminase. Chest radiograph showed no pulmonary infiltration. Reverse transcriptase–PCR (RT-PCR) of the nasopharyngeal swab detected SARS-CoV-2, and RT-PCR of the blood detected dengue virus serotype 2. COVID-19 with dengue fever co-infection was diagnosed. Her symptoms were improved with supportive treatment. Integration of clinical manifestations, history of exposure, laboratory profiles, and dynamic of disease progression assisted the physicians in precise diagnosis. Co-circulating and nonspecific presentations of dengue infection and COVID-19 challenge the healthcare system in tropical countries. To solve this threat, multi-sector strategies are required, including public health policy, development of accurate point-of-care testing, and proper prevention for both diseases.

A study on pulmonary function tests among rice mill workers in Mysuru, Karnataka
Authors: Uma Vijayashankar , L Rajeshwari 
Published: December 2020

Introduction and Aim: Rice is the largest consumed food grain in south India. Rice cultivation, harvesting and milling is done since ages in India. Respiratory diseases are greatly induced by the occupational dusts that are influenced by the duration of exposure. A large amount of dust is produced from rice milling process and hence the workers breathe air mixed with dust into their lungs every day. This study aims to assess the effect of rice mill dust on lung functions among rice mill workers.
Materials and Methods: Fifty non-smoking male adult workers from rice mills were selected for the study and fifty age and sex matched from the general population who were not exposed to such occupational hazard were included as controls. Pulmonary function parameters (FVC, FEV1, FEV1/FVC, PEFR and MVV) were recorded using computerized RMS Helios Spirometer during their working hours in both the groups and were statistically analyzed by using student’s‘t’ test. Further the cases were classified according to the duration of exposure and inter group comparisons were made using one-way Anova.
Results: Rice mill workers showed a significantly greater percentage of decline in FVC, FEV1, PEFR, MVV and also a significant decrease in FEV1/FVC ratio suggestive of obstructive pulmonary disorder. Also, there is a negative correlation between duration of exposure and deterioration of the lung function.
Conclusion: The respiratory parameters were significantly declined among rice mill workers compared to controls.

Published: December 2020

Introduction and Aim: The most emerging area of research in nanotechnology deals with the synthesis of nanoparticles which are of great importance due to its use in various biological fields. Myristica fragrans is commonly known as “nutmeg”. It is popular as a spice and also possesses various therapeutic properties. It has a characteristic pleasant fragrance and a slightly warm taste. It has various therapeutic uses and is widely used. The aim is to assess the anti-inflammatory activity of nutmeg oleoresin mediated silver nanoparticles.
Materials and Methods: The nutmeg oleoresin mediated silver nanoparticles were synthesized and was confirmed by UV Vis spectroscopy. The anti-inflammatory property of the prepared nutmeg oleoresin mediated silver nanoparticles was assessed using albumin denaturation inhibitory assay technique.
Results: The nutmeg oleoresin mediated silver nanoparticles showed good anti-inflammatory activity with increasing concentration of the nanoparticles.
Conclusion: Although a variety of steroidal and non-steroidal anti-inflammatory drugs have been developed, researchers are focusing on natural substances to develop new anti-inflammatory agents. Nutmeg mediated silver nanoparticles showed a good range of inhibition and can be used against inflammation. The myristicin present in the nutmeg maybe responsible for its anti-inflammatory action. Increased albumin denaturation is reported in conditions like in rheumatoid arthritis, diabetes and cancer. Hence this may pay way to manage such conditions.

Published: December 2020

Introduction and Aim: Oxidative stress plays a very important role in endosulfan-induced toxic effects on reproductive organs. Vitamin C is a potent antioxidant which plays an important role in decreasing oxidative stress. The present study was aimed to investigate the protective role of vitamin C against endosulfan-induced testicular toxicity in Wistar rats. To investigate a protective effect of vitamin C against endosulfan induced toxicity on biochemical changes.
Materials and Methods: Seventy male neonatal Wistar rats were divided into seven groups. The group I was taken as the control group, the endosulfan-treated were grouped into II (3 mg/kg body weight (BW) and group III (6 mg/kg BW), Group IV (9 mg/kg BW) and Group V (12 mg/kg BW). Group VI (9 mg/kg BW) and group VII (12 mg/kg BW) were pretreated with vitamin C (20 mg/kg BW) for 60 days. After the experimental procedures, the testicular weight, lactate dehydrogenase (LDH) enzyme and testosterone in plasma, LDH, steroidogenic enzymes 3?-HSD and 17?-HSD in testis were evaluated. One-way ANOVA was used to determine the statistical significance.
Results: Significant improvement in the testicular weight (P<0.05) , LDH (P<0.05) levels both in plasma and testis, increase in testosterone(P<0.001) and steroidogenic enzyme levels(P<0.001) was observed in the group pretreated with vitamin C treated group when compared to the endosulfan treated group.
Conclusion: Vitamin C decreases the toxic effect of endosulfan on testis. The present action might be due to its antioxidative properties.
