Efficacy and safety of dronedarone in patients with amiodarone-induced hyperthyroidism: a clinical study.

Objective: The aim of the study was to examine the safety and efficacy of dronedarone in patients with a history of atrial fibrillation and amiodarone-induced hyperthyroidism.

Patients And Methods: We conducted a prospective study to evaluate the use of amiodarone and dronedarone in 124 patients with a history of paroxysmal atrial fibrillation who had no additional structural heart disease. All patients received amiodarone 200 mg qd.

Drug-induced xenogenization of tumors: A possible role in the immune control of malignant cell growth in the brain?

In recent years, immune checkpoint inhibitors (ICpI) have provided the ground to bring tumor immunity back to life thanks to their capacity to afford a real clinical benefit in terms of patient's survival. Essential to ICpI success is the presence of tumor-associated neoantigens generated by non-synonymous mutations, since a direct relationship between mutation load of malignant cells and susceptibility to ICpI has been confidently established. However, it has been also suggested that high intratumor heterogeneity (ITH) associated with subclonal neoantigens could not elicit adequate immune responses.

Senescence of the brain: focus on cognitive kinases.

Ageing is characterized by alterations in brain anatomy and physiology, finally contributing to an impairment in cognitive functions, such as memory. The most relevant observations indicate that senescent-related cognitive decline is not only due to neuronal loss, instead, functional changes occurring over time play a key role. Overall, these modifications are indeed responsible for an altered interneuronal communication that can represent, rather than morphological modifications, the primum movens leading to cognitive decline.

The aging brain, a key target for the future: the protein kinase C involvement.

The brain represents the primary centre for the regulation and control of all our body activities, receiving and interpreting sensory impulses and transmitting information to the periphery. Most importantly, it is also the seat of consciousness, thought, emotion and especially memory, being in fact able to encode, store and recall any information. Memory is really what makes possible so many of our complex cognitive functions, including communication and learning, and surely without memory, life would lose all of its glamour and purpose.
