Zookeys. 2017 Jan 06;(643):141-155. doi: 10.3897/zookeys.643.8215. eCollection 2017.

Understanding the biodiversity of an area is the first step for establishing effective interventions for conservation, especially when it comes to herpetofauna, since 4.1% and 9.2%, respectively, of Brazilian amphibians and reptiles are endangered. The aim of this study...

Antidepressant-like effect of Hoodia gordonii in a forced swimming test in mice: evidence for involvement of the monoaminergic system.

Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas

Citó MC, Silva MI, Santos LK, Fernandes ML, Melo FH, Aguiar JA, Lopes IS, Sousa PB, Vasconcelos SM, Macêdo DS, Sousa FC.

Hoodia gordonii is a plant species used traditionally in southern Africa to suppress appetite. Recently, it has been associated with a significant increase in blood pressure and pulse rate in women, suggesting sympathomimetic activity. The present study investigated the...

SUMMARY This article gathers information not only from my own personal experiences, but also from the experiences of trans students, staff and faculty members with whom I have worked as a human sexuality educator and consultant, and from my...

Reprint of "Three-dimensional elemental mapping of phosphorus by quantitative electron spectroscopic tomography (QuEST)" [J. Struct. Biol. 160 (2007) 35-48].

Journal of structural biology

Aronova MA, Kim YC, Harmon R, Sousa AA, Zhang G, Leapman RD.
PMID: 18342742
J Struct Biol. 2008 Mar;161(3):322-35. doi: 10.1016/S1047-8477(08)00062-2.

We describe the development of quantitative electron spectroscopic tomography (QuEST), which provides 3-D distributions of elements on a nanometer scale. Specifically, it is shown that QuEST can be applied to map the distribution of phosphorus in unstained sections of...

Reprint of "On the feasibility of visualizing ultrasmall gold labels in biological specimens by STEM tomography" [J. Struct. Biol. 159 (2007) 507-522].

Journal of structural biology

PMID: 18342743
J Struct Biol. 2008 Mar;161(3):336-51. doi: 10.1016/S1047-8477(08)00063-4.

Labeling with heavy atom clusters attached to antibody fragments is an attractive technique for determining the 3D distribution of specific proteins in cells using electron tomography. However, the small size of the labels makes them very difficult to detect...

A method for determination of COD in a domestic wastewater treatment plant by using near-infrared reflectance spectrometry of seston.

Analytica chimica acta

Sousa AC, Lucio MM, Bezerra Neto OF, Marcone GP, Pereira AF, Dantas EO, Fragoso WD, Araujo MC, Galvão RK.
PMID: 17386815
Anal Chim Acta. 2007 Apr 11;588(2):231-6. doi: 10.1016/j.aca.2007.02.022. Epub 2007 Feb 20.

This paper proposes a method for determination of chemical oxygen demand (COD) in domestic wastewater. The proposed method is based on near-infrared reflectance (NIRR) measurements of seston collected from wastewater samples by filtration. The analysis does not require any...

Observation of a Griffiths-like phase in the magnetocaloric compound Tb5Si2Ge2.

Physical review letters

Magen C, Algarabel PA, Morellon L, Araújo JP, Ritter C, Ibarra MR, Pereira AM, Sousa JB.
PMID: 16712265
Phys Rev Lett. 2006 Apr 28;96(16):167201. doi: 10.1103/PhysRevLett.96.167201. Epub 2006 Apr 26.

The onset of a Griffiths-like phase has been observed in Tb5Si2Ge2 (TC=110 K) by means of magnetic susceptibility and small-angle neutron scattering experiments. We show the growth of a ferromagnetic cluster system characterized by an inverse susceptibility exponent lower...

Prediction of the mechanical properties of hydroxyapatite/polymethyl methacrylate/carbon nanotubes nanocomposite.

Journal of nanoscience and nanotechnology

Shokuhfar T, Makradi A, Titus E, Cabral G, Ahzi S, Sousa AC, Belouettar S, Gracio J.
PMID: 19049218
J Nanosci Nanotechnol. 2008 Aug;8(8):4279-84. doi: 10.1166/jnn.2008.an26.

In this work carbon nanotubes (CNTs) were used to increase the strength and toughness of the hydroxyapatite (HA) and consequently to reduce its brittleness. The combination of CNT, HA and polymethyl methacrylate (PMMA) has led to a new composite...

The family inheritance process: motivations and patterns of interaction.

European journal of ageing

Sousa L, Silva AR, Santos L, Patrão M.
PMID: 28798614
