O USO E REGULAMENTAÇÃO DE FREQUÊNCIAS EXTREMAMENTE BAIXAS - ELF
Authors: De Souza João Ivone Cristina 
Published: November 2023

A exposição humana aos campos eletromagnéticos gera uma preocupação constante aos possíveis efeitos na saúde. Estudos científicos têm sido cuidadosos para investigar se a exposição crônica a tais frequências pode ter efeitos adversos à saúde, como efeitos carcinogênicos, neurocomportamentais e sobre o sistema imunológico.Dito isso, em muitos países, existem diretrizes e regulamentos para controlar a exposição humana aos campos eletromagnéticos. A questão que se coloca é saber se as frequências extremamente baixas também dependem de regulamentações e se podem gerar algum dano à saúde. Não há consenso sobre a nomenclatura das faixas de frequência de 0 a 300 Hz. Existem documentos que tratam toda esta faixa como Frequência Extremamente Baixa (sigla ELF, em inglês). Porém, também existem referências que classificam Frequências Extremamente Baixas (ELF) na faixa de 0 a 30 Hz e Frequências Super Baixas (sigla SLF, em inglês) na faixa de 30 a 300 Hz. A utilização de frequências extremamente baixas (ELF, na sigla em inglês), em diversas aplicações, tem sido objeto de debate em relação à necessidade de regulamentação. Muitos países implementam regulamentações gerais para controlar a exposição e garantir a segurança, as quais incluem as ELF. A necessidade de regulamentação depende das preocupações de saúde e segurança associadas a essas frequências de uso, bem como das políticas e normas protegidas em cada país. No Brasil, a entidade responsável pela regulamentação é a ANATEL. Foram adotados os limites recomendados pela Organização Mundial de Saúde – OMS.
Investigation of the Possible Association Between Galectin and Apoptosis in Gastric Cancer Patients

Published: November 2023

Cancer is a type of disease that occurs as a result of the uncontrolled growth of cells, which has been very common in recent years, and some species have a poor prognosis. Galectin-3 is a multifunctional protein and is associated with the developmental process of tumors, including cell growth, adhesion, proliferation and metastasis. Galectin-3 has a broad effect on tumor development, including cell proliferation, apoptosis, cell adhesion, invasion, angiogenesis, and metastasis. Members of the BCLF-2 family are anti-apoptotic molecules required for the proteolytic degradation of the cell by caspases, which is the ultimate drive of programmed cell death, which plays a very important role in the regulation of the apoptotic pathway, ensures the integrity of the mitochondrial membrane and prevents the release of cytochrome C from the mitochondria. NF-kB, which is one of the important factors in cancer formation, is found in the cytoplasm, and there is a correlation between the protein levels of proinflammatory cytokines such as interlukin (IL)-1b, and IL-8, and the high incidence of cancer. There are two types of apoptotic caspases: initiator (apical) caspases and effector (executioner) caspases. Initiator caspases (e.g., caspase-2, -8, -9 and -10) cleave inactive pro-forms of effector caspases, thereby activating them. Effector caspases (e.g., caspase-3, -6, -7) in turn cleave other protein substrates within the cell resulting in the apoptotic process. At least fourteen caspases have so far been implicated in human apoptotic pathway cascade. Among these, caspase-3 is considered to be a major executioner protease in apoptosis. To examine this mechanism in more detail, we aimed to examine the difference between Galectin, BCLF-2, Kaspase3, Kaspas 8, Nfkb levels before and after treatment in operable gastric cancer patients with the Elisa test. In this study, We observed a statistical increase in Galectin, BCLF-2, Kaspase3, Kaspas 8, Nfkb levels when the control group was compared with the preoperative group. There was a statistically significant increase in Galectin, BCLF-2, Nfkb, Caspase3, Caspase 8 levels in the preoperative group compared to the control. There is a statistical increased in Galectin, BCLF-2, Kaspase3, Kaspas 8, Nfkb levels in the postoperative group compared to the control. Although there was no statistical difference in Galectin, BCLF-2, Caspase-3, Caspase-8, Nfkb levels between pre and postoperative groups, a significant decrease was observed in Galectin, BCLF-2, Nfkb levels. A very slight increase was observed in Caspase-3 and Caspase-8 levels. In conclusion, we think that Galectin-3 Bcl-2 and NF-kB may be markers for gastric cancer patients. We think that it is appropriate to conduct this study with more patient groups and a longer period.

Abstract. In the last few decades, various techniques, including spectroscopic, mass spectrometric, chemiluminescence and wet chemical methods, have been developed and applied for the detection of gaseous ammonia (NH3). We developed an online NH3 monitoring system – salicylic acid derivatization reaction and long-path absorption photometer (SAC-LOPAP) – based on a selective colorimetric reaction to form a highly absorbing reaction product and a LOPAP, which could run stably for a long time and be applied to the continuous online measurement of low concentrations of ambient NH3 by optimizing the reaction conditions, adding a constant-temperature module and liquid flow controller. The detection limit reached with this instrument was 40.5 parts per trillion (ppt) with a stripping liquid flow rate of 0.49 mL min−1 and a gas sample flow rate of 0.70 L min−1. An inter-comparison of our system with a commercial Picarro G2103 analyzer (Picarro, USA) in Beijing was presented, and the results showed that the two instruments had a good correlation with a slope of 1.00 and an R2 of 0.96, indicating that the SAC-LOPAP instrument involved in this study could be used for the accurate measurement of NH3.

Published: November 2023

Penelitian ini dilakukan bertujuan untuk mengetahui pengaruh net income, cash flow from operations, dan company size terhadap dividend policy pada perusahaan manufaktur sub sektor industri dasar dan kimia yang terdaftar di Bursa Efek Indonesia periode tahun 2012-2016. Pengujian dilakukan menggunakan uji regresi linier berganda dengan alat bantu SPSS versi 21. Penelitian dilakukan pada 35 observasi dari laporan tahunan dari 7 perusahaan sampel hasil dari pemilihan secara purposive sampling. Dalam pengujian signifikansi secara parsial (Uji-t) menunjukan tidak terdapatnya pengaruh masing-masing variabel independen net income (X1), cash flow from operations (X2), dan company size (X3) terhadap dividend policy (Y). Perusahaan yang memperoleh laba tidak langsung membagikan dividend namun digunakan untuk reinvestasi. Perusahaan dengan jumlah kas terbatas dapat membagikan dividend dalam bentuk stock dividend. Dan perusahaan besar tidak selalu membagikan dividend dikarenakan perekonomian yang belum stabil sehingga mengakibatkan pengelolaan dana perusahaan tidak efektif. Keadaan tersebut membuat perusahaan lebih memprioritaskan pada pertumbuhan perusahaan.

A Concise Review: Nutritional Interventions for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)
Authors: Dhakad Prashant Kumar , Mishra Raghav , Mishra Isha 
Published: November 2023

Wuhan, China reported a novel coronavirus-related sickness in late 2019, which quickly spread into a global epidemic. One crucial factor in combating the coronavirus infection appears to be the presence of a robust, long-lasting, and active immune system. The immune response is affected by several factors, including food. Nutritional insufficiency can cause immune deficits, making infections more likely to cause fatality. Thus, understanding numerous behaviors, particularly dietary habits, is essential to determining their capacity to reduce severe acute respiratory syndrome coronavirus 2 risks and improve prognosis. In this paper, the authors summarize the complex interaction between nutritional status and severe acute respiratory syndrome corona virus 2 infections, as well as the consequences of poor nutrients with regard of the extent to which disease is affected. The literature was compiled by searching a number of reputable scientific databases including Scopus, Science Direct, Springer, Nature, PubMed, Web of Science resources. The accumulating evidence demonstrates that malnutrition impairs the immune system's ability to function, weakening the body's infection resistance. This review emphasizes the significance of nutritional status in the care of coronavirus disease patients as well as demonstrates that functional foods may contribute to better outcomes. Ageing, Obesity, Malnutrition, Undernutrition, Lack of exercise are having a devastating effect on people's health in general and during this coronavirus disease. The severity and prognosis of coronavirus illness seem to be significantly influenced by lifestyle choices, nutritional imbalances, and impaired immune response.
