Different corpus callosum in panic disorder.

Background: Despite hypotheses regarding the neurobiology of panic disorder (PD), its neurobiological basis is still unknown. Study results support that the individual differences in corpus callosum (CC) properties could reflect trait based alterations that predispose individuals to higher anxiety sensitivity, and to disorders associated with stress such as PD. Neuroimaging studies with panic disorder have not been sufficient to explain the pathophysiology of the disease.

Interference of gadolinium dechelated from MR contrast agents by calcium signaling in neuronal cells of GnRH.

Contrast agents (CAs) used in magnetic resonance imaging (MRI) are produced by chelating the metal gadolinium (Gd) with organic ligand molecules to form stable complexes. But, Gd may dissociate from the CAs and subsequently might become toxic to its environment. Besides toxicity, it might inhibit calcium channels on cell membranes and this action could be detrimental to the cells governing biological development.

Effects of gadolinium and gadolinium chelates on intracellular calcium signaling in sensory neurons.

Magnetic resonance imaging (MRI) employs gadolinium chelates as contrast agents to provide signal enhancement in radiological images. However, the instability of the chelates presents a challenge as the released gadolinium ion (Gd) from the chelates becomes toxic to the surrounding biological tissue. Chelates such as gadodiamide, gadoterate meglumine, gadobutrol and gadobenate dimeglumine are common contrast agents used in clinics.
