The link between abnormalities of calcium handling proteins and catecholaminergic polymorphic ventricular tachycardia.

Catecholaminergic polymorphic ventricular tachycardia (CPVT), a rare autosomal dominant or recessive disease, usually results in syncope or sudden cardiac death. Most CPVT patients do not show abnormal cardiac structure and electrocardiogram features and symptoms, usually onset during adrenergically mediated physiological conditions. CPVT tends to occur at a younger age and is not easy to be diagnosed and managed.

Exposure to carcinogenic PAHs for the vendors of broiled food.

Three types of popular vendors, including meat and non-meat food (e.g, fishballs), vendor group (I), rice sausage sandwiches vendor group (II), and roasted corn on-the-cob vendor group (III), from the night markets of Taiwan were chosen for this research. The average concentrations of carcinogenic polycyclic aromatic hydrocarbons (car-PAHs) were 2445 ng/m3 for vendor (II), 2276 ng/m3 for vendor (II), and 133 ng/m3 for vendor (III).
