1. Impact of Air Pollutant on Heart Rate Variability in Healthy Young Adults
Abstract Background: Air pollution and sex independently affect cardiac autonomic control, which can be assessed by heart rate variability (HRV). The research hypothesis is that individuals exposed to low concentrations of pollution have higher cardiac autonomic modulation compared to those exposed to high concentrations and that women have better cardiac a

2. Sustainable Synthetic Strategies for the Preparation of Low Molecular Weight Drugs by Biotech Routes
For billions of years, the phenomena of life and biocatalysis have been intertwined. If in the beginning biocatalysis was fundamental for the origin of life, currently it is very important for the cleaner production of pharmaceuticals and fine chemical intermediates. There is no doubt that drugs have brought great benefits to humanity, but currently, the exp

3. Selective formation of neodymium phosphate from iron-neodymium magnet waste
Abstract Neodymium-iron-boron alloy, Nd2Fe14B, is used as a material for magnets. Neodymium is one of the valuable and expensive rare earth elements and is often recovered to reduce costs and environmental impact. Recently, a method for recovering neodymium as neodymium phosphate from mixed solutions was reported. This method was very useful because the main

4. Synthesis and Evaluation of the Fungal Activity of New Pyrazole-Carboxamides against Colletotrichum gloeosporioides
The pyrazole core has been recognized by their biological properties and included in the synthesis of modern agrochemicals. Part of these studies consists of making structural modifications to pesticides for commercial purposes to increase efficacy. In this article, we present the synthesis of four new pyrazol-4-carboxamide 8a-8d derivatives (PCD), through a

5. DESENVOLVIMENTO DE METODOLOGIAS ANALÍTICAS PARA DETERMINAÇÃO DE CLORPIRIFÓS EM AMOSTRAS AQUOSAS EMPREGANDO A MICROEXTRAÇÃO LÍQUIDO-LÍQUIDO DISPERSIVA SEGUIDA POR HPLC-UV
The miniaturized extraction techniques use less aggressive methods to the environment, since they generate less waste and spend a minimum of organic solvents, besides having a good selectivity and specificity in the extractions. In this context, liquid-liquid dispersive microextraction (DLLME) has been highlighting. Thus, the present article describes an opt

7. Conservation Agriculture in Trouble? Estimating the Economic Impact of an Eventual Glyphosate Prohibition in Spain
RESUMO: O controle de plantas daninhas é um aspecto crucial em muitos sistemas de agricultura de conservação, uma vez que os custos e a economia de tempo de evitar o plantio direto estão intimamente ligados ao uso de herbicidas eficazes e ecologicamente corretos. Isso levou ao uso difundido de glifosato em fazendas administradas sob agricultura de conser

8. Zn, Co, Cr, As, and genotoxic effects in the ichthyofauna species from polluted and non-polluted/protected estuaries of the São Paulo coast, Brazil
Abstract: The human impact on estuarine regions results in an increasing concentration of trace elements in the environment, exposing aquatic organisms. In this study, Zn, Co, Cr, and As were determined in the muscle tissue of some fish species from Santos-São Vicente (SSV), a recognized polluted region, and in the Cananeia estuary (CAN). Genotoxicity was a

12. Anthropogenic impacts on aquatic bacteria: a perspective from the tropics
Resumo O bacterioplâncton compreende um grupo altamente diversificado de microrganismos, que são dominantes nos ecossistemas aquáticos e desempenham um papel central no funcionamento desses ecossistemas e nos ciclos biogeoquímicos. Devido às suas elevadas taxas de dispersão e de mudança na composição, bem como alta adaptabilidade e plasticidade, os
