The greatest disadvantage of the halothane, widely used in the anaesthesiology is its ability to cause liver damage. After halothane anaesthesia mild liver enzyme elevation in the one fifth of the patients was detected. The incidence of fatal halothane hepatitis is rare. It depends on several risk factors: on the genetic predisposition, repeated halothane anaesthetics, female sex, age of patient, obesity, intrahepatic hypoxia and enzyme induction. In the pathophysiology of liver toxicity the metabolism of halothane and immune functions play an important role. In this review the last results of researches concerning to the hepatotoxicity of halothane are summarised and the authors call the attention on the opportunity of its effective prevention.

Surgery remains the primary treatment for solid malignant tumors, but controlling postoperative tumor recurrence and metastasis continues to be a major challenge. Understanding the factors that influence tumor recurrence and metastasis after surgery, as well as the underlying biological mechanisms, is critical. Previous studies suggest that anesthetic agents may increase the risk of tumor recurrence and metastasis in patients with cancer, but the mechanisms underlying these findings remain unclear.

Malignant hyperthermia (MH) is a potentially fatal disorder triggered by volatile anesthetics or succinylcholine, inducing a hypermetabolic crisis in susceptible patients. The caffeine-halothane contracture test (CHCT) remains a gold standard for MH detection. The authors describe a pregnant patient with a history of exertional rhabdomyolysis, who required urgent MH screening for administration of MH-triggering anesthetics.

In this study, we develop the synthesis methods of fluoroalkenes and fluoroenynes via Suzuki-Miyaura and Sonogashira cross-coupling reactions using novel multihalogenated fluorovinyl ethers, which are easily prepared from the reaction between phenols and 2-bromo-2-chloro-1,1,1-trifluoroethane (halothane). These reactions make use of the unique structure of multihalogenated fluorovinyl ethers, which contains a reactive bromine atom, to afford a series of fluoroalkenes and fluoroenynes in moderate to high yields.

Doxorubicin (DOX) is a widely used anticancer agent, but its clinical application is limited by significant off-target hepatorenal toxicity. Tadalafil (TAD), a selective phosphodiesterase-5 inhibitor used mainly for erectile dysfunction and pulmonary arterial hypertension, has shown potential in reducing oxidative stress. This study investigated TAD's chemoprotective effects and underlying mechanisms in DOX-induced hepatorenal toxicity in rats over 12 days.
