Critical Role of the Circadian Clock in Memory Formation: Lessons from Aplysia

Frontiers in Molecular Neuroscience, 2011
Unraveling the complexities of learning and the formation of memory requires identification of the cellular and molecular processes through which neural plasticity arises as well as recognition of the conditions or factors through which those processes ...

Axial coordination of ferric Aplysia myoglobin

Journal of Biological Chemistry, 1989
Resonance Raman spectra of ferric Aplysia myoglobin in the ligand-free and the azide-bound forms have been studied over a wide pH range to determine the coordination states of the heme iron atom. In the hydroxide form at high pH (approximately 9) the iron is six-coordinate and is in a high/low spin equilibrium.

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

The malleable brain: plasticity of neural circuits and behavior: A review from students to students [PDF]

, 2017
One of the most intriguing features of the brain is its ability to be malleable, allowing it to adapt continually to changes in the environment. Specific neuronal activity patterns drive long-lasting increases or decreases in the strength of synaptic ...

Excitatory postsynaptic potentials in rat neocortical neurons in vitro. III. Effects of a quinoxalinedione non-NMDA receptor antagonist [PDF]

, 1990
1. Intracellular microelectrodes were used to obtain recordings from neurons in layer II/III of rat frontal cortex. A bipolar electrode positioned in layer IV of the neocortex was used to evoke postsynaptic potentials.

Recent Advancements in the Characterization of D‐Amino Acid and Isoaspartate Post‐Translational Modifications

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 218-230, March/April 2026.
ABSTRACT One of the great triumphs of mass spectrometry‐based peptide and protein characterization is the characterization of their modifications as most modifications have a characteristic mass shift. What happens when the modification does not change the mass of the peptide?

3‐D Modeling of Differential Exhumation of Ultrahigh‐Pressure Metamorphic Rocks Driven by Increasing Plate Divergence

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Petrological and seismic constraints suggest differential sampling depth for ultrahigh pressure (UHP) metamorphic rocks exposed in different segments of the fossil subduction zone of the Western Alps. However, the mechanisms for the observed differential exhumation remain to be understood. Here, we account for the continental margin subduction
