(AMER ACAD PEDIATRICS, 2006-05)OBJECTIVE. Cellular immunity has classically been described as the defense mechanism for viral infections. The development of cellular or humoral immune responses will depend on a repertoire of cytokines produced by numerous ...
-
(Blackwell Publishing, 2013)T helper type 17 (Th17) lymphocytes are found in high frequency in tumour-burdened animals and cancer patients. These lymphocytes, characterized by the production of interleukin-17 and other pro-inflammatory cytokines, ...
-
(1995)We consider a system of the form u’' + au’ = Hv(u, v)-h(t) v’' + bv’ = Hu(u, v)-k(t), where h, k are locally integrable and T-periodic, and H is a C1 function defined on (0,∞)x(0,∞), for which a good model is given by H(u, ...

(Elsevier, 2017)We have prepared a nanoelectrode ensemble containing vertically aligned single walled carbon nanotubes (SWCNTs) using a non-template molecular self-assembling strategy. We used a bottom-up construction approach to assemble ...

(Elsevier Ltd, 2017)© 2017 Elsevier Ltd We have prepared a nanoelectrode ensemble containing vertically aligned single walled carbon nanotubes (SWCNTs) using a non-template molecular self-assembling strategy. We used a bottom-up construction ...
-
(Elsevier, 1998)Here, we present the analysis of wood to determine trace elements in tree rings. We have irradiated wood pieces directly, for thick target PIXE, and also thin samples obtained by chemical treatment of the wood material. ...
-
(Lippincott Williams & Wilkins, 2016)We reported earlier that TNF-alpha, a proinflammatory cytokine implicated in many inflammatory disorders causing orofacial pain, increases the activity of Cdk5, a key kinase involved in brain development and function and ...
-
(Springer, 2018)Perinatal asphyxia (PA) is a relevant cause of death at the time of labour, and when survival is stabilised, associated with short- and long-term developmental disabilities, requiring inordinate care by health systems and ...
-
(2004)Tau is a neuronal microtubule-associated protein that plays a central role in many cellular processes, both physiological and pathological, such as axons stabilization and Alzheimer's disease. Despite extensive studies, ...
-
(IOS PRESS, 2009)Alzheimer’s disease (AD) is characterized by the accumulation of protein filaments, namely extracellular amyloid-β (Aβ) fibrils and intracellular neurofibrillary tangles, which are composed of aggregated hyperphosphorylated ...
-
Tau protein binds to pericentromeric DNA: a putative role for nuclear tau in nucleolar organization (COMPANY OF BIOLOGISTS LTD, 2006-05-15)The microtubule-associated tau protein participates in the organization and integrity of the neuronal cytoskeleton. A nuclear form of tau has been described in neuronal and non-neuronal cells, which displays a nucleolar ...
-
(Magnolia Press, 2019)Ectinogonia Spinola 1837 is composed of 22 species to date, but its taxonomic history has been complex and is still unresolved. The species of the Santiagan Province of Chile Central are particularly complex because they ...
-
(2014)A morphological comparison of two populations assigned to Orestias agassii from the Chilean Altiplano with the syntypes from Peru and Bolivia was performed. The results suggest that populations of Chile do not match the ...

-
(PEERJ, 2016)Two extremely-long necked elasmosaurids, AMNH 1495, holotype of Hydralmosaurus serpentinus, and AMNH 5835, previously referred to H. serpentinus, are here reviewed in detail. Unique features of the cervical vertebrae, ...
-
(Wiley, 2021)Aim Delimiting recently diverged species is challenging. During speciation, genetic differentiation may be distributed unevenly across the genome, as different genomic regions can be subject to different selective pressures ...
-
(Wiley & Sons, 2015)The quantum states and thermodynamical properties of the Te vacancy in CdTe are addressed by first principles calculations, including the supercell size and quasiparticle corrections. It is shown that the 64-atoms supercell ...
-
(MDPI, 2018-04)Telomerase, the enzyme responsible for cell immortality, is an important target in anti-cancer drug discovery. Boldine, an abundant aporphine alkaloid of Peumus boldus, is known to inhibit telomerase at non-toxic concentrations. ...
-
(2012)We present detailed pollen and charcoal records from Lago Pichilafquén (~. 41°S) to decipher the effects of climate change and varying disturbance regimes on the composition and structure of the vegetation on the Andean ...
