Auxin production couples endosperm development to fertilization.

Nature plants

Figueiredo DD, Batista RA, Roszak PJ, Köhler C.
PMID: 27251719
Nat Plants. 2015 Nov 23;1:15184. doi: 10.1038/nplants.2015.184.

In flowering plants, seed development is preceded by a double fertilization event, whereby two male sperm cells fuse with two female gametes: the egg and central cells. The fertilized egg cell will form the embryo, and the fertilized central...

Inference of topology and the nature of synapses, and the flow of information in neuronal networks.

Physical review. E

Borges FS, Lameu EL, Iarosz KC, Protachevicz PR, Caldas IL, Viana RL, Macau EEN, Batista AM, Baptista MS.
PMID: 29548150
Phys Rev E. 2018 Feb;97(2):022303. doi: 10.1103/PhysRevE.97.022303.

The characterization of neuronal connectivity is one of the most important matters in neuroscience. In this work, we show that a recently proposed informational quantity, the causal mutual information, employed with an appropriate methodology, can be used not only...

OBJECTIVE: : To compare gait spatiotemporal parameters of healthy and ACL reconstructed subjects in order to classify the status of gait normality.METHODS: : Fourteen healthy subjects and eight patients submitted to ACL reconstruction walked along a walkway while the...

Development of paroxysmal nocturnal hemoglobinuria in CALR-positive myeloproliferative neoplasm.

Journal of blood medicine

Fraiman YS, Cuka N, Batista D, Vuica-Ross M, Moliterno AR.
PMID: 27313483
J Blood Med. 2016 May 30;7:107-10. doi: 10.2147/JBM.S103473. eCollection 2016.

Paroxysmal nocturnal hemoglobinuria (PNH), a disease characterized by intravascular hemolysis, thrombosis, and bone marrow failure, is associated with mutations in the PIG-A gene, resulting in a deficiency of glycosylphosphatidylinositol-anchored proteins. Many hypotheses have been posed as to whether PNH...

Free-Form Region Description with Second-Order Pooling.

IEEE transactions on pattern analysis and machine intelligence

Carreira J, Caseiro R, Batista J, Sminchisescu C.
PMID: 26357341
IEEE Trans Pattern Anal Mach Intell. 2015 Jun;37(6):1177-89. doi: 10.1109/TPAMI.2014.2361137.

Semantic segmentation and object detection are nowadays dominated by methods operating on regions obtained as a result of a bottom-up grouping process (segmentation) but use feature extractors developed for recognition on fixed-form (e.g. rectangular) patches, with full images as...

Alkaloids in Erythrina by UPLC-ESI-MS and In Vivo Hypotensive Potential of Extractive Preparations.

Evidence-based complementary and alternative medicine : eCAM
