Nanocellulose Composites as Smart Devices With Chassis, Light-Directed DNA Storage, Engineered Electronic Properties, and Chip Integration.

The rapid development of green and sustainable materials opens up new possibilities in the field of applied research. Such materials include nanocellulose composites that can integrate many components into composites and provide a good chassis for smart devices. In our study, we evaluate four approaches for turning a nanocellulose composite into an information storage or processing device: 1) nanocellulose can be a suitable carrier material and protect information stored in DNA.

A new innovative real-time tracking method for flying insects applicable under natural conditions.

Background: Sixty percent of all species are insects, yet despite global efforts to monitor animal movement patterns, insects are continuously underrepresented. This striking difference between species richness and the number of species monitored is not due to a lack of interest but rather to the lack of technical solutions. Often the accuracy and speed of established tracking methods is not high enough to record behavior and react to it experimentally in real-time, which applies in particular to small flying animals.

Evaluation of the influence of global DNA methylation level in patients with acute coronary syndrome.

DNA methylation is one of the mechanisms of epigenetic regulation and is observed in mammals to maintain a normal expression pattern of the genes. Aberrant profiles of DNA methylation have already been associated with cardiovascular diseases. We evaluated 190 patients with Acute Coronary Syndrome (ACS) and 75 patients without ACS (non-ACS).

Acute coronary syndrome: Relationship between genetic variants and TIMI risk.

Acute Coronary Syndrome (ACS) is a multifactorial disease, including the genetic factor, caused by coronary artery obstruction by atheroma. Some genetic variants have been described as risk factors for this disease. Its early diagnosis and stratification of risk of death by Thrombolysis in Myocardial Infarction (TIMI) are important.

Diabetes and cardiovascular events in high-risk patients: Insights from a multicenter registry in a middle-income country.

Aims: The aim of this study was to determine the rate of major clinical events and its determinants in patients with previous cardiovascular event or not, and with or without diabetes from a middle-income country.

Methods: REACT study is a multicenter registry conducted between July 2010 and May 2013 in Brazil. Patients were eligible if they were over 45years old and high cardiovascular risk.

Analysis and redesign of a knowledge database for a drug-drug interactions alert system.

Physicians tend to ignore drug-drug interactions alerts, this is due to the large amount of irrelevant interactions displayed and the interface in which these alerts are shown. The high rate of clinically inadequate alerts produce "alerts fatigue". This high number of incorrect alerts predisposes physicians to underestimate the electronic prescription systems as useful tools in their practice.

Evolution of medical informatics in bibliographic databases.

Medical informatics became a medical specialty during the last years and this is evidenced by a great amount of journal articles regarding the subject published worldwide. We compared the presentation of Medical Informatics in two different bibliographic databases: MEDLINE and LILACS (Latin American and Caribbean Literature on the Health Sciences). Previous studies described how Medical Informatics was represented in MEDLINE, but we wanted to compare it to a regional database as LILACS.
