Even though the relationship between antiarrhythmic drug usage and subsequent prostate cancer (PCa) risk has recently been highlighted, relevant findings in the previous literature are still inconsistent. In addition, very few studies have attempted to investigate the association between sodium
BACKGROUND
Supraventricular arrhythmias after thoracotomy for pulmonary resections are well documented. There has been considerable interest in their incidence, nature, predictability from preoperative assessment and treatment. The purpose of this study is to define prevalence, type, risk factors
It has been shown that sessions of total body hyperthermia (rectal temperature - 40.0-41.8 degrees C) and artificial hyperglycemia (22-23 mmol/l) in combination with chemotherapy in cancer patients with severe cardiac arrhythmias should follow antiarrhythmic pretreatment and should be accompanied by
We experienced 3 patients(Cases 1, 3, and 4)with pelvic tumor-related rectal tenesmus showing favorable responses to antiarrhythmic drugs. Based on this experience, we administered antiarrhythmic drugs preferentially to 2 others with tumor derived rectal tenesmus(Cases 2 and 5), and again obtained
Class II antiarrhythmics or β-blockers are antisympathetic nervous system agents that act by blocking β-adrenoceptors. Despite their common clinical use, little is known about the effects of β-blockers on free intracellular calcium (Ca2+i), an important
BACKGROUND
The objective of this study was to determine the association between the use of antiarrhythmic agents and the risk of malignant neoplasm of liver and intrahepatic bile ducts (MNLIHD).
METHODS
We used the research database of the Taiwan National Health Insurance Program to conduct a
OBJECTIVE
Long-term usage of the antiarrhythmic drug digoxin has been connected to lowered risk of prostate cancer. A recent study has suggested that beta-blockers might also have similar risk-decreasing effects. We evaluated the association between use of digoxin, beta-blocker sotalol, and other
In-vitro studies have suggested that the antiarrhythmic drug digoxin might restrain the growth of cancer cells by inhibiting Na+/K+-ATPase. We evaluated the association between cancer mortality and digoxin, sotalol and general antiarrhythmic drug use in a retrospective cohort study. The study
Previous research has suggested that thyroid hormone receptor alpha 1 (THRα1), a hormone responsive splice variant, may play a role in breast cancer progression. Whether THRα1 can be exploited for anti-cancer therapy is unknown. The antiproliferative and antitumor effects of dronedarone, an
Experimental evidence suggests that hERG and hEAG potassium channels may serve as important cancer therapy targets because either of the channel blockade or inactivation by different methods leads to inhibition of cancer cells growth and proliferation. However, there is no known hEAG specific
OBJECTIVE
To evaluate the utility of amiodarone and its derivative dronedarone as novel drug repositioning candidates in EOC and to determine the potential pathways targeted by these drugs.
METHODS
Drug-predict bioinformatics platform was used to assess the utility of amiodarone as a novel
Iodinated and radioiodinated analogs of propranolol and N,N-dimethylpropranolol were synthesized wherein an iodophenyl moiety replaced the naphthalene ring of the parent drug. These new compounds were evaluated not only for their beta-adrenergic blocking and antiarrhythmic activities but also for
Hyperpolarization-elicited potassium currents in GH3/B6 cells bathed in high-potassium external solution were recorded to assess effects of the class III antiarrhythmic agent E-4031 on the inactivating inward-rectifying potassium current (IK,IR). E-4031 potently blocked IK,IR with an IC50 value of
Kv10.1 (Eag1, or KCNH1) is a human potassium-selective channel associated with tumor development. In this work, we study the interaction of the drug dronedarone with Kv10.1. Dronedarone presents two chemical modifications aimed to lessen side effects produced by its parent molecule, the
