Residues of four pesticides in groundwaters were surveyed during one year in an agricultural area in southern Brazil. The methods for separation, identification and quantification of the compounds included high-performance liquid chromatography with diode array detection (HPLC-DAD) and liquid chromatography with electrospray interface tandem mass spectrometry (LC-ESI-MS/MS). A pre-concentration step based on solid-phase extraction with 200 mg C18 cartridges was applied. All the analytical parameters ...

Anthropogenic contamination of beaches in the south of Brazil was assessed by detection of Escherichia coli, human mastadenovirus species C (HAdV-C) and F (HAdV-F) and hepatitis E virus (HEV). Sampling was carried out in October (2016), and in January, April and July (2017). Water, sediment, sea surface microlayer (SML), bivalves, and air sentinel samples were evaluated. Quantitative microbiological risk assessment (QMRA) was used to estimate the probability of swimmer infection. HAdV-C was present in ...

We aimed to describe the SARS-CoV-2 lineages circulating early pandemic among samples with S gene dropout and characterize the receptor-binding domain (RBD) of viral spike protein. Adults and children older than 2 months with signs and symptoms of COVID-19 were prospectively enrolled from May to October in Porto Alegre, Brazil. All participants performed RT-PCR assay, and samples with S gene dropout and cycle threshold < 30 were submitted to high-throughput sequencing (HTS). 484 out of 1,557 participants ...

Chikungunya is a mosquito-borne virus that has been causing large outbreaks in the Americas since 2014. In Brazil, Asian-Caribbean (AC) and East-Central-South-African (ECSA) genotypes have been detected and lead to large outbreaks in several Brazilian states. In Rio Grande do Sul (RS), the southernmost state of Brazil, the first cases were reported in 2016.We employed genome sequencing and epidemiological investigation to characterise the Chikungunya fever (CHIKF) burden in RS between 2017-2021.We detected ...

Introduction. The shortening of clinical crown is evidenced in situations where there is gingival excess, making it a limiting factor for ideal positioning of orthodontic appliances. In these cases, preliminary surgical correction is necessary, in order to restore the dental proportions of the crowns. Laser therapy used after surgery helps tissue repair, reduces edema and postoperative pain. Objectives. This paper aims to report a clinical case of periodontal surgery (gingivectomy) associated with ...
