This work presents a novel electrochemical method for the determination of oxcarbazepine (OXC) in urine and pharmaceutical samples using a flow injection analysis (FIA) system coupled to multiple-pulse amperometric (MPA) detection on a boron-doped diamond electrode (BDDE). The unique voltammetric profile of OXC on the BDDE, consisting of two electrochemical oxidation processes between +1.6 and +1.8 V versus Ag/AgCl/3.0 mol L−1 KCl generating cationic radical species that undergo two electrochemical reduction ...

Hepatitis E virus (HEV), an emerging virus associated with acute hepatic disease, leads to thousands of deaths worldwide. HEV has already been reported in Brazil; however, there is a lack of epidemiological and molecular information on the genetic variability, taxonomy, and evolution of HEV. It is thus unclear whether hepatitis E is a neglected disease in Brazil or it has low relevance for public health in this country. Here, for the first time, we report the presence of HEV in Northeast Brazil. ...

A 250 μg W + 200 μg Rh coating (W–Rh) on the integrated platform of a transversely heated graphite atomiser (THGA) was used as a permanent chemical modifier for the determination of Cd in digests of biological materials and dissolved sediments by electrothermal atomic absorption spectrometry (ETAAS). The W–Rh permanent modifier was as efficient as NH4H2PO4 + Mg(NO3)2 and Pd + Mg(NO3)2 conventional modifiers for obtaining good Cd thermal stabilisation in the decomposed samples. The permanent W–Rh modifier ...

Ultrasound-assisted extraction is compared with slurry sampling and microwave-assisted acid digestion for the determination of cadmium, lead and copper in biological samples and cadmium in sediment samples by electrothermal atomic absorption spectrometry (ETAAS). The main advantage of using an ultrasound-assisted extraction in comparison to slurry sampling is a doubling of the tube lifetime for all the chosen analytes, most likely because the sample matrix was not introduced into the atomiser, avoiding ...

A tungsten carbide-rhodium coating on the integrated platform of a transversely heated graphite atomizer was used as a permanent chemical modifier for the determination of Pb in digests of biological materials and sediments by electrothermal atomic absorption spectrometry. Coating with 250 µg W+200 µg Rh was as efficient as a Pd+Mg(NO 3 ) 2 conventional modifier for obtaining good Pb recoveries (95.2-102.3%). The W-Rh permanent modifier remained stable for approximately 350 firings when 20 µl of digested ...

A tungsten carbide–rhodium coating on the integrated platform of a transversely heated graphite atomiser was used as a permanent chemical modifier for the determination of Pb in sediment slurries by electrothermal atomic absorption spectrometry. Slurries were sonicated for 20 s before being delivered to the previously W–Rh treated platform. The number of sediment particles introduced into the atomiser for delivery of a 20 µl slurry aliquot ranged from 1300 to 3400. The permanent W–Rh modifier remains ...

Iodine is an essential micro nutrient, and a deficiency or excessive intake of this mineral is related to changes in thyroid function. In Brazil, both deficiency and excessive intake of iodine are common; however, excessive intakes have recently been observed. Thus, the objective of the present study was to assess the iodine concentration in maternal milk, taking into account the salt iodine concentration of the participating households and in the infants’ urine. Urine samples from 33 infants (less ...

Arterial blood pressure (BP) is a very useful variable in clinical practice. Its measurement is simple, inexpensive and easy; it is worth noting that BP should be accurately obtained, following the recommendations of the VI Brazilian Guidelines on Hypertension (DBH VI)1. Office BP measurement is the central parameter for the diagnosis, treatment and follow-up of systemic arterial hypertension (SAH), being directly, continuously and independently related to the risk of fatal and non-fatal cardiovascular ( ...

In recent years, we have seen scientists attempt to model and explain human dynamics and in particular human movement. Many aspects of our complex life are affected by human movement such as disease spread and epidemics modeling, city planning, wireless network development, and disaster relief, to name a few. Given the myriad of applications, it is clear that a complete understanding of how people move in space can lead to considerable benefits to our society. In most of the recent works, scientists ...

Jaguars (Panthera onca), like other apex predators, are highly susceptible to habitat loss and fragmentation given their low demographic potential and large habitat area requirements. Across their range, the Pantanal is considered critical for the jaguar's long-term conservation. Here we provide the first multi-scale path selection function model for jaguars, and the first empirically-based movement model covering the entire Pantanal ecosystem. Out of eight investigated variables, six were related ...

The direct determination of bismuth in urine and whole blood samples is proposed by graphite furnace atomic absorption spectrometry. The pyrolytic integrated platform of the THGA tube was coated with 250 µg W + 200 µg Rh to increase the tube lifetime. Urine samples were diluted (1 + 1 v/v) and blood samples (1 + 4 v/v) in a solution containing 1.0% v/v HNO3 + 0.2% Triton X-100, and 20 µl of the resulting dilute samples were delivered into the W-Rh modified platform together with 10 µl of 10 mg l−1 Rh solution. ...

Adenomatous polyposis coli (APC) germline mutations are responsible for the occurrence of familial adenomatous polyposis (FAP). Somatic mutations lead to malignant transformation of adenomas. In this context, considering the significance of APC germline mutations in FAP, we aimed to identify APC germline mutations. In the present study, 20 FAP patients were enrolled. The determination of APC germline mutations was performed using sequencing, and the mutations were compared with clinical markers (gender, ...

ROH are continuous homozygous segments that are common in individuals and populations. The ability of these homozygous segments to give insight into a population's genetic events makes them a useful tool that can provide information about the demographic evolution of a population over time. ...

Tinctures are medicinal plant extracts obtained by extraction with a hydroalcoholic solution (70%) by percolation (PER). This process takes about 26 h to prepare, in addition to using a large amount of solvent. In our research, passion fruit leaf tinctures were obtained using extract with the same pressurized hydroalcoholic solution as in an intermittent process. The objective was to demonstrate that this emerging technology can be economical and profitable. An optimization using Central Composite ...

Light-based therapies and diagnoses including photodynamic therapy (PDT) have been used in many fields of medicine, including the treatment of non-oncological diseases and many types of cancer. PDT require a light source and a light-sensitive compound, called photosensitizer (PS), to detect and destroy cancer cells. After absorption of the photon, PS molecule gets excited from its singlet ground state to a higher electronically excited state which, among several photophysical processes, can emit light ( ...
