Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

open access: yesSedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Nature of the Pigment of Aplysia depilans [PDF]

open access: yesNature, 1955
BY heating an aqueous solution of the actual excretion of the Mediterranean sea-slug Aplysia depilans, the violet pigment is separated from its protein part. The colour of the aqueous solution varies conformably with the pH, from blue (pH 1—2) to garnet red (pH 8—12.0).

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

open access: yesSedimentology, EarlyView.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

A unified approach to model peripheral nerves across different animal species [PDF]

open access: yesPeerJ, 2017
Peripheral nerves are extremely complex biological structures. The knowledge of their response to stretch is crucial to better understand physiological and pathological states (e.g., due to overstretch).

Drafting the calmodulation playbook: Emerging structural insights into transient receptor potential channel regulation by calmodulin

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Calmodulin (CaM) is a ubiquitous calcium (Ca2+) sensor that translates intracellular Ca2+ signals into modulation of hundreds of effector proteins including ion channels. CaM is increasingly recognized as a key regulator of the transient receptor potential (TRP) channel family, yet the underlying ‘calmodulation playbook’ is only ...

Serotonin Induces Structural Plasticity of Both Extrinsic Modulating and Intrinsic Mediating Circuits In Vitro in Aplysia Californica

open access: yesCell Reports, 2019
Summary: Long-term sensitization of the gill withdrawal reflex in Aplysia requires heterosynaptic, modulatory input that is mediated in part by the growth of new synaptic connections between sensory neurons and their follower cells (intrinsic mediating ...

Increase in Growth Cone Size Correlates with Decrease in Neurite Growth Rate

open access: yesNeural Plasticity, 2016
Several important discoveries in growth cone cell biology were made possible by the use of growth cones derived from cultured Aplysia bag cell neurons, including the characterization of the organization and dynamics of the cytoskeleton.

Hemoprotein Nitric Oxide Synthase in Aplysia Californica [PDF]

open access: yes, 2008
Nitric oxide (NO) plays a crucial role in neuronal signaling in a variety of eukaryotic and prokaryotic organisms. Nitric oxide synthases (NOS) are heme-containing monooxygenases that catalyze the oxygen dependent oxidation of L-arginine to NO and L ...
