Long-QT founder variant T309I-Kv7.1 with dominant negative pattern may predispose delayed afterdepolarizations under β-adrenergic stimulation.

The variant c.926C > T (p.T309I) in KCNQ1 gene was identified in 10 putatively unrelated Czech families with long QT syndrome (LQTS).

Out-of-Hospital Cardiac Arrest Due to Ventricular Fibrillation in a 5-Year-Old Pediatric Patient.

Out-of-hospital cardiac arrest in pediatric population is rare and predominantly has respiratory aetiology. Authors present the relatively unique case of out-of hospital cardiac arrest in 5-years old pediatric patient due to ventricular fibrillation (VF) as the initial rhythm during the advanced life support. The patient was resuscitated by his parents and the initial rhythm was VF.

Bioaccumulation of heavy metals, metalloids, and chlorine in ectomycorrhizae from smelter-polluted area.

Ectomycorrhizal (ECM) fungi contribute to the survival of host trees on metal-rich soils by reducing the transfer of toxic metals into roots. However, little is known about the ability of ECM fungi to accumulate elements in ectomycorrhizae (ECMs). Here we report Ag, As, Cd, Cl, Cu, Sb, V, and Zn contents in wild-grown Norway spruce ECMs collected in a smelter-polluted area at Lhota near Příbram, Czech Republic.
