Objectives: To study the effect of single-dose pilocarpine hydrochloride 5 mg on the whole unstimulated and stimulated salivary flow in patients suffering from thyroid cancer treated with radioiodine therapy, and to investigate the changes in vital signs during the treatment.
Subjects And Methods: Five such patients were referred with complaints of dry mouth, rampant caries, and pain in the parotid gland region or history of chronic recurrent suppurative sialodenitis. A single dose of 5 mg pilocarpine hydrochloride was administered to each patient and blood pressure, heart rate, body temperature and salivary secretion rate were monitored at 1, 2 and 3 h.
Results: A significant elevation of unstimulated and stimulated saliva flow rate was observed in four patients without significant alteration of the monitored vital signs.
Conclusions: Treatment with pilocarpine hydrochloride may be beneficial in the case of impaired salivary function in patients treated with radioiodine.

Clinical Relevance: Accommodation is crucial for clear near vision and is predominantly affected by presbyopia. The ability to modulate accommodative function with eye drops could offer a pharmacological approach to manage presbyopia.
Background: To investigate the effects of different concentrations of pilocarpine eye drops on ocular accommodation in young volunteers.

Our previous in silico data indicated an overrepresentation of the ZF5 motif in the promoters of genes in which circadian oscillations are altered in the ventral hippocampus in the pilocarpine model of temporal lobe epilepsy in mice. In this study, we test the hypothesis that the Zbtb14 protein oscillates in the hippocampus in a diurnal manner and that this oscillation is disrupted by epilepsy. We found that Zbtb14 immunostaining is present in the cytoplasm and cell nuclei.

: Despite the availability of antiepileptic drugs (AEDs) that can manage seizures, they often come with cognitive side effects. Furthermore, the role of oxidative stress and neuroinflammatory responses in epilepsy and the limitations of current AEDs necessitate exploring alternative therapeutic options. Medicinal plants, e.

Epilepsy is a chronic neurological disorder that affects nearly 50 million people worldwide. Experimental evidence suggests that epileptic neurons are linked to the endocannabinoid system and that inhibition of the FAAH enzyme could have neuroprotective effects by increasing the levels of endogenous endocannabinoid anandamide. In this context, the use of macamides as therapeutic agents in neurological diseases has increased in recent years.

Reactive astrogliosis and acidosis, common features of epileptogenic lesions, express a high level of astrocytic acid-sensing ion channel-1a (ASIC1a), a proton-gated cation channel and key mediator of responses to neuronal injury. This study investigates the role of astrocytic ASIC1a in cognitive impairment following epilepsy. Status epilepticus (SE) in C57/BL6 mice was induced using lithium-pilocarpine; the impact of ASIC1a on astrocytes was assessed using rAAV-ASIC1a-NC and rAAV-ASIC1a-shRNA, injected in the CA3 region of mice.
