An integrated platform for 2‐D and 3‐D optical and electrical mapping of arrhythmias in Langendorff‐perfused rabbit hearts

The Journal of Physiology, EarlyView.
Abstract figure legend Integrated multimodal platform for panoramic cardiac mapping in isolated heart experiments. On the left, an image of the experimental setup during data acquisition showing a Langendorff‐perfused rabbit heart surrounded by three optical cameras (CAM A, B and C) positioned 120° apart, each coupled with high‐power LEDs for panoramic

Carbachol Induces Ca2+-Dependent Contraction via Muscarinic M2 and M3 Receptors in Rat Intestinal Subepithelial Myofibroblasts

Journal of Pharmacological Sciences, 2009
.: Intestinal myofibroblasts (IMFs) that exist adjacent to the basement membrane of intestines have contractility and contribute to physical barriers of the intestine.

Ca2+ transients are not required as signals for long-term neurite outgrowth from cultured sympathetic neurons [PDF]

, 1990
A method for clamping cytosolic free Ca2+ ([Ca2+]i) in cultures of rat sympathetic neurons at or below resting levels for several days was devised to determine whether Ca2+ signals are required for neurite outgrowth from neurons that depend on Nerve ...

The Antipsychotic Aripiprazole Induces Cytotoxicity in Bladder Cancer Cells While Preserving Urothelial and Bladder Function

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
Current bladder cancer therapies can cause toxicity and bladder dysfunction. Brief intravesical‐like aripiprazole exposure reduced bladder cancer cell viability and was associated with redox stress and caspase‐3 activation, while ex vivo findings suggested preserved bladder structure and function, warranting further investigation as a potential ...

In vitro exposure to Escherichia coli decreases ion conductance in the jejunal epithelium of broiler chickens. [PDF]

PLoS ONE, 2014
Escherichia coli (E. coli) infections are very widespread in poultry. However, little is known about the interaction between the intestinal epithelium and E. coli in chickens.

Redox regulation of type-I inositol trisphosphate receptors in intact mammalian cells. [PDF]

, 2018
A sensitization of inositol 1,4,5-trisphosphate receptor (IP3R)-mediated Ca2+ release is associated with oxidative stress in multiple cell types. These effects are thought to be mediated by alterations in the redox state of critical thiols in the IP3R ...

Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT The enteric nervous system (ENS), a key component of the gut–brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)—a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or ...

Inhibitory Effect of the Phosphoinositide 3-Kinase Inhibitor LY294002 on Muscarinic Acetylcholine Receptor-Induced Calcium Entry in PC12h Cells

Journal of Pharmacological Sciences, 2007
Phosphoinositide-3 kinase (PI3K) and phospholipase C (PLC) utilize the same phosphoinositides as substrates to produce different signaling molecules. These enzymes are activated by a similar set of cell signaling mechanisms, i.e., tyrosine kinases and G ...

Presynaptic M1 muscarinic cholinoceptors mediate inhibition of excitatory synaptic transmission in the hippocampus in vitro [PDF]

, 1990
The effects of the cholinoceptor agonist, carbachol (CCh), were examined in the rat hippocampal slice preparation. Intracellular recordings from CA1 pyramidal neurones revealed that CCh (1–3 μM) inhibited excitatory postsynaptic responses evoked by ...

Time‐dependent bladder activity changes in streptozotocin‐induced female diabetic rats

Physiological Reports
This study aimed to investigate the long‐term physiological and morphological changes in the bladders of diabetic rats. Sixty‐nine female Sprague–Dawley rats were divided into a control and six diabetic (3 days and 2, 4, 8, 12, and 24 weeks after ...
