The genus Botryococcus comprises a group of cosmopolitan species of freshwater colonial green algae, some of which synthesize and accumulate an unusually high level (15-76%) of liquid hydrocarbons. This characteristic suggests the possibility of exploiting species from this group...

Physiological and biochemical impacts induced by mercury pollution and seawater acidification in Hediste diversicolor.

The Science of the total environment

Freitas R, de Marchi L, Moreira A, Pestana JLT, Wrona FJ, Figueira E, Soares AMVM.

The present study evaluated the impacts of predicted seawater acidification and Hg pollution, when stressors were acting alone and in combination, on the polychaete Hediste diversicolor. Polychaetes were exposed during 28days to low pH (7.5), Hg (5μg/L) and pH7.5+Hg,...

[28]Hexaphyrin derivatives for anion recognition in organic and aqueous media.

Chemical communications (Cambridge, England)

Figueira F, Farinha AS, Muteto PV, Polêto MD, Verli H, Gomes MT, Tomé AC, Cavaleiro JA, Tomé JP.

A practical course was given to undergraduate biology students enrolled in the elective course "Introduction to Genetic Engineering" at the Federal University of São Carlos (UFSCar), São Paulo, Brazil. The goal of the course was to teach current molecular...

Genes differentially expressed in Theobroma cacao associated with resistance to witches' broom disease caused by Crinipellis perniciosa.

Molecular plant pathology

Leal GA, Albuquerque PS, Figueira A.
PMID: 20507499
Mol Plant Pathol. 2007 May;8(3):279-92. doi: 10.1111/j.1364-3703.2007.00393.x.

SUMMARY The basidiomycete Crinipellis perniciosa is the causal agent of witches' broom disease of Theobroma cacao (cocoa). Hypertrophic growth of infected buds ('brooms') is the most dramatic symptom, but the main economic losses derive from pod infection. To identify...

Study of air-induced paper discolorations by infrared spectroscopy, X-ray fluorescence, and scanning electron microscopy.

Applied spectroscopy

Ferreira A, Figueira F, Pessanha S, Nielsen I, Carvalho ML.
PMID: 20149275
