Bogas AC, Ferreira AJ, Araújo WL, Astolfi-Filho S, Kitajima EW, Lacava PT, Azevedo JL.
PMID: 26090305
Springerplus. 2015 Jun 13;4:258. doi: 10.1186/s40064-015-1037-0. eCollection 2015.

Endophytes colonize an ecological niche similar to that of phytopathogens, which make them candidate for disease suppression. Anthracnose is a disease caused by Colletotrichum spp., a phytopathogen that can infect guarana (Paullinia cupana), an important commercial crop in the...

Use of Self-Matching to Control for Stable Patient Characteristics While Addressing Time-Varying Confounding on Treatment Effect: A Case Study of Older Intensive Care Patients.

International journal of statistics in medical research

Han L, Pisani MA, Araujo KL, Allore HG.
PMID: 27123153
Int J Stat Med Res. 2016;5:8-16. doi: 10.6000/1929-6029.2016.05.01.2. Epub 2016 Jan 08.

Exposure-crossover design offers a non-experimental option to control for stable baseline confounding through self-matching while examining causal effect of an exposure on an acute outcome. This study extends this approach to longitudinal data with repeated measures of exposure and...

Homeostatic maintenance via degradation and repair of elastic fibers under tension.

Scientific reports

Alves C, Araújo AD, Oliveira CL, Imsirovic J, Bartolák-Suki E, Andrade JS, Suki B.
PMID: 27279029
Sci Rep. 2016 Jun 09;6:27474. doi: 10.1038/srep27474.

Cellular maintenance of the extracellular matrix requires an effective regulation that balances enzymatic degradation with the repair of collagen fibrils and fibers. Here, we investigate the long-term maintenance of elastic fibers under tension combined with diffusion of general degradative...

Studies on the respiration rate of free and immobilized cells of cephalosporium acremonium in cephalosporin C production .

Biotechnology and bioengineering

Araujo ML, Giordano RC, Hokka CO.
PMID: 10397815
Biotechnol Bioeng. 1999 Jun 05;63(5):593-600. doi: 10.1002/(sici)1097-0290(19990605)63:5<593::aid-bit9>3.0.co;2-q.

Bioprocesses using filamentous fungi immobilized in inert supports present many advantages when compared to conventional free cell processes. However, assessment of the real advantages of the unconventional process demands a rigorous study of the limitations to diffusional mass transfer...

Statistics of the critical percolation backbone with spatial long-range correlations.

Physical review. E, Statistical, nonlinear, and soft matter physics

Araújo AD, Moreira AA, Costa Filho RN, Andrade JS.
PMID: 12636857
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Feb;67(2):027102. doi: 10.1103/PhysRevE.67.027102. Epub 2003 Feb 24.

We study the statistics of the backbone cluster between two sites separated by distance r in two-dimensional percolation networks subjected to spatial long-range correlations. We find that the distribution of backbone mass follows the scaling ansatz, P(M(B)) approximately M(-(alpha+1))(B)f(M(B)/M(0)),...

Periodic neural activity induced by network complexity.

Physical review. E, Statistical, nonlinear, and soft matter physics

Paula DR, Araújo AD, Andrade JS, Herrmann HJ, Gallas JA.

We study a model for neural activity on the small-world topology of Watts and Strogatz and on the scale-free topology of Barabási and Albert. We find that the topology of the network connections may spontaneously induce periodic neural activity,...

Chemisorption of phosphoric acid and surface characterization of As passivated AlN powder against hydrolysis.

By simply refluxing a commercial AlN powder in a mixture solution of ethanol, H(3)PO(4), and Al(H(2)PO(4))(3) for 24 h at 80 degrees C, the powder was successfully passivated against hydrolysis. The phosphate layer formed on the surface of AlN...

Potentiometric determination of urea by sequential injection using Jack bean meal crude extract as a source of urease.
