Characterization and long-term trends of hypoxia in the northern Gulf of Mexico: Does the science support the action plan?
long-term trends of hypoxia the northern Gulf of Mexico
2016/5/18
We update and reevaluate the scientific information on the distribution, history, and causes of continental
shelf hypoxia that supports the 2001 Action Plan for Reducing, Mitigating, and Controlling ...
Ecosystems in Action: Lessons from Marine Ecology about Recovery, Resistance, and Reversibility
sustainabilit resilience kelp forest
2015/12/11
The study of ecosystems in action, by measuring ecosystem recovery from disturbance, resistance to alterations, and the reversibility of ecosystem
changes, highlights features of natural communities ...
Action Potential Modulation of Neural Spin Networks Suggests Possible Role of Spin
Action potential modulation nuclear spin cognitive pixel
2015/7/30
In this paper we show that nuclear spin networks in neural membranes are modulated by action potentials through J-coupling, dipolar coupling and chemical shielding tensors and perturbed by microscopic...
Bose-Einstein condensation of tunnelling photons in the brain cortex as a mechanism of conscious action
Quantum brain dynamics (QBD) consciousness
2015/7/30
Mind is supposed to be a macroscopic quantum wave governing the dynamics of the quantum coherent cytoskeletal protein system inside the cytoplasm of the brain cortical neurons. Its dynamical timescale...
Content and action:The guidance theory of representation
action intentionality mental content reference representation
2015/7/30
The current essay introduces the guidance theory of representation, according to which the content and intentionality of representations can be accounted for in terms of the way they provide guidance ...
Evolutionary Advantages of Inter-Subjectivity and Self-Consciousness through Improvements of Action Programs
consciousness evolution self-consciousness intersubjectivity phenomenal consciousness autorepresentation identification with conspecifics anxiety limitation action program improvement
2015/7/15
Evolutionary advantages of consciousness and intersubjectivity are part of current philosophical debates on the nature of consciousness. Both are linked and intersubjectivity is sometimes considered a...
Investigation of the action of phosphatase of regenerating liver on PTEN using murine models
Phosphatase of Regenerating Liver PTEN Mouse Models
2015/5/25
The addition and removal of phosphate groups is a key regulatory mechanism for many cellular processes. The balance between phosphorylation and dephosphorylation is delicate and must be maintained in ...
Exploring the mechanism of action of spore photoproduct lyase
spore photoproduct lyase enzyme kinetics
2015/5/21
Spore photoproduct lyase (SPL) is a radical SAM (S-adenosylmethionine) enzyme that is responsible for the repair of the DNA UV damage product 5-thyminyl-5,6-dihydrothymine (also called spore photoprod...
A Test of the Hypothesis That Environmental Chemicals Interfere With Thyroid Hormone Action in Human Placenta
endocrine disruption thyroid hormone placenta cyp1a1
2014/12/12
Thyroid hormone is essential for normal brain development and recognition of this has led to universal screening of newborns for thyroid function to ensure that circulating levels of thyroid hormone a...

Motor neurons spinal cord lower back levator muscle muscle motor neurons cell death neurotrophic factor
2014/12/11
Motoneurons of the spinal nucleus of the bulbocavernosus (SNB) reside in the lower lumbar spinal cord and innervate the bulbocavernosus (BC) and levator ani (LA) muscles. Adult males have larger BC an...
The action of T- and CS -syndrome pyrethroids on voltage-sensitive calcium channels in rat brain
Nerve terminals deltamethrin chrysanthemum ester calcium influx and neurotransmitter release fluorescence assay calcium influx of deltamethrin stimulation
2014/12/11
Isolated presynaptic nerve terminals (synaptosomes) prepared from rat brain were used to evaluate the action of a classic T-syndrome (cismethrin) and CS-syndrome (deltamethrin) pyrethroid on voltage-s...
