(American Ornithologist Society, 2002)We studied the effect of forest fragmentation on the nesting biology and reproductive success of three species of tapaculos (Rhinocryptidae) in relation to forest size, edge effects, and disturbance from livestock or logging ...
-
(2008)The Xylocopinae contains four tribes with species which show a range of nesting habits, from solitary to social. The Manueliini is the sister group to all other Xylocopine tribes, with one genus, Manuelia, of three species ...
-
(Soc. Biolgia Chile, 2016)Background: In one-piece nesting termites, which nest and forage in a single piece of wood, soldier production increases during the swarming period, i.e. when the risk of invasion of their substrate and hence of their ...
-
(MDPI, 2021)Glioblastoma (GBM) is the most aggressive and common primary tumor of the central nervous system. It is characterized by having an infiltrating growth and by the presence of an excessive and aberrant vasculature. Some of ...
-
(Kluwer Academic/Plenum Publishers, 1996)1. Expression of the apamin-sensitive K+ channel (SK+) in rat skeletal muscle is neurally regulated. The regulatory effect of the nerve over the expression of some muscle ion channels has been attributed to the electrical ...
-
(Cell Press, 2021)The transcriptome analysis of injured Xenopus laevis tadpole and mice suggested that Neurod4L.S., a basic-helix-loop-helix transcription factor, was the most promising transcription factor to exert neuroregeneration after ...
-
(MDPI, 2018-04)Progressive neurodegenerative pathologies in aged populations are an issue of major concern worldwide. The microtubule-associated protein tau is able to self-aggregate to form abnormal supramolecular structures that include ...
-
Neuroinflammation: Implications for the pathogenesis and molecular diagnosis of Alzheimer's disease (ELSEVIER SCIENCE INC, 2007-05-31)During the past few years, an increasing set of evidence has supported the major role of deregulation of the interaction patterns between glial cells and neurons in the pathway toward neuronal degeneration. Neurons and ...
-
(American Chemical Society, 2017)© 2016 American Chemical Society.Disturbed iron homeostasis, often coupled to mitochondrial dysfunction, plays an important role in the progression of common neurodegenerative diseases such as Parkinson’s disease (PD). ...
-
(Elsevier B.V., 2006-10-21)The tumor necrosis factor alpha (TNFα) plays a dual role in producing either neurodegeneration or neuroprotection in the central nervous system. Despite that TNFα was initially described as a cell death inductor, ...
-
(Taylor & Francis Ltd, 2001-05-04)Monoamine oxidase-A (MAO-A) (amiflamine (AMF) and 4-methylthioamphetamine (MTA)) and MAO-B (Ldeprenyl) inhibitors were found to be cytotoxic in a concentration-dependent manner for RCHTcells derived from adult rat ...
-
(ELSEVIER, 2004-12)The carotid body (CB) is the main arterial chemoreceptor. The most accepted model of arterial chemoreception postulates that carotid body glomus (type 1) cells are the primary receptors, which are synaptically connected ...

-
(SPRINGER, 2006-10)The reaction under very mild conditions of the polyspirophosphazene copolymer with pendant diphenylphosphine groups {[NP(O2C12H8)](0.85)[NP(OC6H4PPh2)(2)](0.15)}(n) (I) (O2C12H8= 2,2'-dioxybiphenyl) with [Au(THT)Cl] (THT ...
-
(Sociedad Chilena de Quimica, 2011)Four compounds that belong to two structure types, namely dibenzylbutyrolactone and sesterterpenoids, were obtained from the extract of the strain Aspergillus sp. (2P-22), isolated from a marine sponge, Cliona chilensis. ...
-
(SERNAGEOMIN, 2015)Here we studied new fossil chondrichthyans from two localities, Rio de Las Minas, and Sierra Dorotea, both in the Magallanes Region, southernmost Chile. In Rio de Las Minas, the upper section of the Priabonian Loreto ...
-
(Paleontological Society, 2014)We present new records of chondrichthyans recovered from strata of Maastrichtian age of the López de Bertodano Formation, Seymour (=Marambio) Island, and from levels of latest Campanian age of the Santa Marta Formation, ...
-
(Nature Research, 2021)In the last decades, several discoveries have uncovered the complexity of mammalian evolution during the Mesozoic Era, including important Gondwanan lineages: the australosphenidans, gondwanatherians, and meridiolestidans ...
-
(Elsevier Ltd, 1996)The reactions of CpFe(dppe)I with thiophenes in the presence of T1PF6 afforded the new complexes [CpFe(dppe)thiophenes]PF6 (thiophenes = thiophene, 2-methyl-thiophene, 3-methyl-thiophene, 2,5-dimethyl-thiophene, benzothiophene ...
