Effects of AZFc (b2/b4, b1/b3, b2/b3, and gr/gr) deletions and primary duplications on the outcomes of the first intracytoplasmic sperm injection treatment cycle: A single‐center retrospective cohort study

open access: yesAndrology, EarlyView.
Abstract Background Current advances in high‐throughput sequencing technology enable the precise identification of Y chromosome microdeletion and primary duplication in infertile couples, but the mechanism and clinical significance of these mutations in assisted reproductive techniques remain unclear.

Independent derivations of the axis of arrhythmia for predicting drug‐induced torsades de pointes

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose: Torsades de pointes is a potentially lethal ventricular arrhythmia that can be induced by many classes of drugs. The risk for a given drug depends upon the combination of cardiac ion channels that it targets. The axis of arrhythmia quantifies that risk. It is a conceptual line in the electrophysiology that describes the
