Development of novel nanocomposite-modified photoelectrochemical sensor based on the association of bismuth vanadate and MWCNT-grafted-molecularly imprinted poly(acrylic acid) for dopamine determination at nanomolar level.

This study proposes the development of a new photoelectrochemical (PEC) sensor for the determination of dopamine (DA) at nanomolar levels. The PEC sensor was based on a physical mixture of bismuth vanadate (BiVO) with nanocomposite molecularly imprinted poly(acrylic acid) (MIP-AA) grafted onto MWCNT by using the surface-controlled radical polymerization strategy with an INIFERTER reagent. XRD, diffuse reflectance spectroscopy (DRE), SEM, TEM, and TGA were employed to characterize the materials.

KMT2A-MLLT1 and the Novel SEC16A-KMT2A in a Cryptic 3-Way Translocation t(9;11;19) Present in an Infant With Acute Lymphoblastic Leukemia.

About 25% of the patients with the translocation t(11;19)(q23;p13.3)/KMT2A-MLLT1 present three-way or more complex fusions, associated with a worse prognosis, suggesting that a particular mechanism creates functional KMT2A fusions for this condition. In this work, we show a cryptic three-way translocation t(9;11;19).

[Regional and dynamics characteristics of dengue in Brazil: a retrospective study].

Dengue epidemics occur typically in the warmest months without qualitative differences for the Brazilian geographic regions. However, this disease has an important quantitative difference. We observe two clusters in the country regarding the number of case notifications: The first cluster is formed by the North-East and South-East regions, that sum about 86% of the all notifications; and the second is formed by the South, North and Center-West regions.
