Mice lacking neuronal calcium sensor-1 show social and cognitive deficits
(2020-03-02)Neuronal calcium sensor-1 or Frequenin is a calcium sensor widely expressed in the nervous system, with roles in neurotransmission, neurite outgrowth, synaptic plasticity, learning, and motivated behaviours. Neuronal calcium ... -
Microencapsulation of oxolinic acid with chitosan beads
(2018-12)Chitosan microspheres were synthesized by the method of ionic gelling. The oxolinic acid was encapsulated in chitosan microspheres with different concentrations, which was corroborated by FT-IR of the spheres showing typical ... -
Microhabitat segregation and physiological differences in two species of intertidal porcellanid crabs (Genus Petrolisthes) on the southern coast of Chile
(2011)Intertidal crustaceans have a high degree of physiological plasticity, which allows them to withstand periods of water emersion. In this study we examine the physiological constraints that determine the distribution and ... -

Microsatellite evidence for sperm storage and multiple paternity in the marine gastropod Crepidula coquimbensis
(2011)In gregarious species with copulation and internal fertilization, male–male competition and female cryptic choice may affect reproductive success of both sexes. We carried out a molecular analysis to study paternity and ... -
Microseismicity Appears to Outline Highly Coupled Regions on the Central Chile Megathrust
(2021)We compiled a novel microseismicity catalog for the Central Chile megathrust (29°–35°S), comprising 8,750 earthquakes between April 2014 and December 2018. These events describe a pattern of three trenchward open half-ellipses, ... -
Microwave-assisted synthesis of localized surface plasmon resonance enhanced bismuth selenide (Bi2Se3) layers for non-enzymatic glucose sensing
(2020-01-01)Three-dimensional (3D) bismuth selenide (Bi2Se3) nanostructures were synthesized by microwave synthesis using water as a solvent and hydrazine hydrate as a reducing agent and exfoliated into few layers of Bi2Se3. Bi2Se3- ... -
Mini-symposium: Behavioral ecology of crustaceans
