Roles of Beta2- and Beta3-Adrenoceptor Polymorphisms in Hypertension and Metabolic Syndrome

open access: yesInternational Journal of Hypertension, 2010
Hypertension, diabetes mellitus (especially type 2 diabetes mellitus), metabolic syndrome and obesity are rapidly growing public health problems. Sympathetic nerve activation is observed in obesity, hypertension and diabetes mellitus, which have strong ...

Global parameter search reveals design principles of the mammalian circadian clock [PDF]

open access: yes, 2008
Background: Virtually all living organisms have evolved a circadian (~24 hour) clock that controls physiological and behavioural processes with exquisite precision throughout the day/night cycle.

Relationships of Adrenoceptor Polymorphisms with Obesity

open access: yesJournal of Obesity, 2011
Obesity, hypertension, and type 2 diabetes are rapidly growing public health problems. Heightened sympathetic nerve activity is a well-established observation in obesity, hypertension, and type 2 diabetes.

Neurotransmitters and Neuromodulators [PDF]

open access: yesActa geneticae medicae et gemellologiae, 1974
In the central nervous system, besides the neurotransmitters, the occurrence of substances which modify neuronal excitability has been proposed. Since their effect is a matter of modulating neuronal responsiveness, these substances may be called neuromodulators.Examples of neurotransmitters or putative neurotransmitters in the central nervous system ...

Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study [PDF]

open access: yes, 2015
This paper presents a computational model which estimates the postsynaptic conductance change of mammalian Type I afferent peripheral process when airborne acoustic waves impact on the tympanic membrane. A model of the human auditory periphery is used to

Single-Cell Transcriptomic Reveals Dual and Multi-Transmitter Use in Neurons Across Metazoans

open access: yesFrontiers in Molecular Neuroscience, 2021
Neurotransmitter expression is widely used as a criterion for classifying neurons. It was initially thought that neurons express a single type of neurotransmitter, a phenomenon commonly recognized as Dale's principle: “one neuron, one transmitter ...

Maturation of a central brain flight circuit in Drosophila requires Fz2/Ca2+ signaling

open access: yeseLife, 2015
The final identity of a differentiated neuron is determined by multiple signaling events, including activity dependent calcium transients. Non-canonical Frizzled2 (Fz2) signaling generates calcium transients that determine neuronal polarity, neuronal ...

Inhibition of the mitochondrial pyruvate carrier protects from excitotoxic neuronal death. [PDF]

open access: yes, 2017
Glutamate is the dominant excitatory neurotransmitter in the brain, but under conditions of metabolic stress it can accumulate to excitotoxic levels.
