Neuroendocrine tumours are rare in the gynaecologic tract, comprising approximately 2% of all gynaecological tumours. They have an aggressive behaviour and are a diagnostic and clinical challenge, due to their rarity and the lack of standardized therapeutic approaches. There...

GLP1 and glucagon co-secreting pancreatic neuroendocrine tumor presenting as hypoglycemia after gastric bypass.

Endocrinology, diabetes & metabolism case reports

Guimarães M, Rodrigues P, Pereira SS, Nora M, Gonçalves G, Albrechtsen NW, Hartmann B, Holst JJ, Monteiro MP.
PMID: 26266036
Endocrinol Diabetes Metab Case Rep. 2015;2015:150049. doi: 10.1530/EDM-15-0049. Epub 2015 Jul 15.

UNLABELLED: Post-prandial hypoglycemia is frequently found after bariatric surgery. Although rare, pancreatic neuroendocrine tumors (pNET), which occasionally are mixed hormone secreting, can lead to atypical clinical manifestations, including reactive hypoglycemia. Two years after gastric bypass surgery for the treatment...

MALE OSTEOPOROSIS.

Revista brasileira de ortopedia

Oliveira LG, Guimarães ML.
PMID: 27022584
Rev Bras Ortop. 2015 Dec 12;45(5):392-6. doi: 10.1016/S2255-4971(15)30425-0. eCollection 2010.

Population aging is a reality that is being faced worldwide, and Brazil is no different. Osteoporosis was considered to be a postmenopausal women's disease for many years. Men have many development and hormonal factors that differentiate their skeletal maturation,...

Effects of ferumoxytol on quantitative PET measurements in simultaneous PET/MR whole-body imaging: a pilot study in a baboon model.

EJNMMI physics

Borra RJ, Cho HS, Bowen SL, Attenberger U, Arabasz G, Catana C, Josephson L, Rosen BR, Guimaraes AR, Hooker JM.
PMID: 26501808
EJNMMI Phys. 2015 Dec;2(1):6. doi: 10.1186/s40658-015-0109-0. Epub 2015 Feb 26.

BACKGROUND: Simultaneous PET/MR imaging depends on MR-derived attenuation maps (mu-maps) for accurate attenuation correction of PET data. Currently, these maps are derived from gradient-echo-based MR sequences, which are sensitive to susceptibility changes. Iron oxide magnetic nanoparticles have been used...

Vocal cord dysfunction: a frequently forgotten entity.

Case reports in pulmonology

Campainha S, Ribeiro C, Guimarães M, Lima R.
PMID: 23024876
Case Rep Pulmonol. 2012;2012:525493. doi: 10.1155/2012/525493. Epub 2012 Sep 16.

Vocal cord dysfunction (VCD) is a disorder characterized by unintentional paradoxical adduction of the vocal cords, resulting in episodic shortness of breath, wheezing and stridor. Due to its clinical presentation, this entity is frequently mistaken for asthma. The diagnosis...

Non-Standard Genetic Codes Define New Concepts for Protein Engineering.

Life (Basel, Switzerland)

Bezerra AR, Guimarães AR, Santos MA.
PMID: 26569314
Life (Basel). 2015 Nov 12;5(4):1610-28. doi: 10.3390/life5041610.

The essential feature of the genetic code is the strict one-to-one correspondence between codons and amino acids. The canonical code consists of three stop codons and 61 sense codons that encode 20% of the amino acid repertoire observed in...

Effects of Arg90 Neutralization on the Enzyme-Catalyzed Rearrangement of Chorismate to Prephenate.

Journal of chemical theory and computation

Guimarães CR, Udier-Blagović M, Tubert-Brohman I, Jorgensen WL.
PMID: 26641683
J Chem Theory Comput. 2005 Jul;1(4):617-25. doi: 10.1021/ct0500803.

Chorismate mutase (CM) is an enzyme that catalyzes the Claisen rearrangement of chorismate to prephenate. In a recent effort to understand the basis for catalysis by CM, Kienhöfer and co-workers (J. Am. Chem. Soc. 2003, 125, 3206-3207) reported results...

Dynamics of the transverse Ising model with next-nearest-neighbor interactions.

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

Guimarães PR, Plascak JA, de Alcantara Bonfim OF, Florencio J.
PMID: 26565176
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Oct;92(4):042115. doi: 10.1103/PhysRevE.92.042115. Epub 2015 Oct 07.

We study the effects of next-nearest-neighbor (NNN) interactions on the dynamics of the one-dimensional spin-1/2 transverse Ising model in the high-temperature limit. We use exact diagonalization to obtain the time-dependent transverse correlation function and the corresponding spectral density for...

One step forward: contrasting the effects of Toe clipping and PIT tagging on frog survival and recapture probability.

Amphibians have been declining worldwide and the comprehension of the threats that they face could be improved by using mark-recapture models to estimate vital rates of natural populations. Recently, the consequences of marking amphibians have been under discussion and...

Human Cytomegalovirus Protease:  Why is the Dimer Required for Catalytic Activity?.

Journal of chemical theory and computation

de Oliveira CA, Guimarães CR, Barreiro G, de Alencastro RB.

Breastfeeding is fundamental for infant health. However, its median duration in Brazil is very short, and national campaigns since the mid-1980s have attempted to revert this situation. In the present paper, data on breastfeeding are compared for two population-based...
