Choline and Choline alphoscerate Do Not Modulate Inflammatory Processes in the Rat Brain [PDF]

open access: yes, 2017
Choline is involved in relevant neurochemical processes. In particular, it is the precursor and metabolite of acetylcholine (ACh). Choline is an essential component of different membrane phospholipids that are involved in intraneuronal signal ...

Direct Gravity‐Induced Modulation of Cardiac Conduction Pathways Evidenced Through Propagation Features in Electrophysiological Mapping

open access: yesAdvanced Materials Technologies, EarlyView.
A high‐density wearable body‐surface potential mapping array reveals how gravity reshapes cardiac conduction in real time. By resolving spatiotemporal delay patterns invisible to conventional ECG, the platform uncovers posture‐dependent electrophysiological adaptations across the thorax.

Localization of Na pumps in the tracheal epithelium of the dog. [PDF]

open access: yes, 1979
Binding of [3H]ouabain by the dog's tracheal epithelium shows a nonspecific component depending linearly on ouabain concentration, and a specific saturable component with a Km of 10(-7) M.

Effects of Gabaergic phenols on phospholipid bilayers as evaluated by 1H-NMR [PDF]

open access: yes, 2013
The phenols propofol and thymol, and lately carvacrol, eugenol and chlorothymol, have been shown to act as positive allosteric modulators on GABAA receptor, which is the main inhibitory receptor of the central nervous system.

A Tac1‐Expressing Brainstem Pathway Underlies the Pathogenesis of Trigeminal Neuralgia

open access: yesAdvanced Science, EarlyView.
A critical TG‐Sp5CTac1‐PBNTac1 pathway drives trigeminal neuropathic pain (TNP). Tac1‐expressing parabrachial nucleus (PBNTac1) neurons exhibit heightened responses to innocuous stimuli in TNP, and chemogenetic inhibition of these neurons effectively prevents TNP development.

Functional characterization of a glutamate/aspartate transporter from the mosquito Aedes aegypti [PDF]

open access: yes, 2003
Glutamate elicits a variety of effects in insects, including inhibitory and excitatory signals at both neuromuscular junctions and brain. Insect glutamatergic neurotransmission has been studied in great depth especially from the standpoint of the ...

Diabetes-induced alterations in urothelium function:Enhanced ATP release and nerve-evoked contractions in the streptozotocin rat bladder [PDF]

open access: yes, 2018
Up to 80% of patients with diabetes mellitus develop lower urinary tract complications, most commonly diabetic bladder dysfunction (DBD). The aim of this study was to investigate the impact of diabetes on the function of the inner bladder lining ...
