The outbreak of COVID-19 has created an unprecedent global crisis. While the polymerase chain reaction (PCR) is gold standard method for detecting active SARS-CoV-2 infection, alternative high-throughput diagnostic tests are a significant value to meet universal testing demands. Here, we describe new design MasSpec Pen technology integrated electrospray ionization (ESI) direct analysis clinical swabs and investigate its use screening. redesigned system incorporates disposable sampling device...
Bee venom has therapeutics and pharmacological properties. Further toxicological studies on animal models are necessary due to the severe allergic reactions caused by this product. Here, Caenorhabditis elegans was used as an in vivo toxicity model, while breast cancer cells were evaluate benefits. The bee utilized research collected from Apis mellifera species found Northeast Brazil. cytotoxicity measured MTT assay MDA-MB-231 J774 A.1 during 24 - 72 hours of exposure. C. at L4 larval stage...
Ion chromatography (IC) is one of the most used analytical methods for determination inorganic cations and anions, as well organic ions. It considered a method separation with simple steps, low cost good efficiency in chromatographic separation. In addition, it has validation metrics such sensitivity, selectivity, precision, robustness, detection limit quantification. IC easily replaces conventional wet chemistry methods, which tend to have more analysis steps. The easy extraction samples,...
The COVID-19 pandemic boosted the development of diagnostic tests to meet patient needs and provide accurate, sensitive, fast disease detection. Despite rapid advancements, limitations related turnaround time, varying performance metrics due different sampling sites, illness duration, co-infections, need for particular reagents still exist. As an alternative test, we present urine analysis through flow-injection-tandem mass spectrometry (FIA-MS/MS) as a powerful approach diagnosis, targeting...
The nematode Caenorhabditis elegans (C. elegans) is a prevailing model which commonly utilized in variety of biomedical research arenas, including neuroscience. Due to its transparency and simplicity, it becoming choice organism for conducting imaging behavioral assessment crucial understanding the intricacies nervous system. Here, methods required neuronal characterization using fluorescent proteins tasks are described. These simplified protocols microscopy assays examine connections...
A ingestão frequente de água contendo concentração flúor acima do limite estabelecido pela legislação brasileira causa uma doença chamada fluorose dentária. Atualmente, o monitoramento nível na para consumo humano é realizado utilizando métodos potenciométricos, cromatográficos ou colorimétricos, que são relativamente caros e utilizam equipamentos difícil deslocamento análises campo. Portanto, surge a necessidade desenvolver alternativos, visando rapidez, praticidade, mobilidade redução...
Countless deleterious effects on human health and the environment are promoted by action of air pollutants. Thus, it is necessary development analytical methods to identify quantify efficiently ions present in atmospheric particulate matter. This study proposes a new methodology for simultaneous quantification 12 organic (Lactate, Acetate, Propionate, Formate, Butyrate, Methanesulfonate, Pyruvate, Monochloroacetate, Trifluoroacetate, Succinate, Oxalate Citrate), inorganic anions (fluoride,...

The Caenorhabditis elegans (C. elegans) is a model organism that has been increasingly used in health and environmental toxicity assessments. However, few studies have quantified the uptake bioaccumulation of animal's chemical species after acute or chronic exposure. quantification such elements vivo can assist seek to relate exposure concentration possible biological effects. Therefore, this study first propose method quantitative analysis 21 ions by ion chromatography, which be applied...
