Aims: The purpose of this study was to describe the perceptions of women who sought court protection orders for domestic violence (PODV) about actions to implement laws intended to disarm their abusers. Methods: We identified female victims of intimate partner violence (IPV) in New York and Los Angeles primarily through family courts and records of police calls for domestic violence. Of these, 782 were surveyed and asked about their experiences seeking PODV from courts, judges ordering the removal of firearms from defendants, and if firearms were actually surrendered or confiscated. Results: Of the 542 victims who had obtained a PODV and knew whether their abuser owned a firearm, 82 (15%) reported that their abuser owned a firearm. Although state law either allowed or mandated judges issuing PODVs to require abusers to surrender their firearms, 21 victims (26%) reported that judges used this authority. Ten victims (12% of victims with armed abusers) reported that their abuser had either surrendered all of his firearms or had the firearms seized. When victims reported that the judge ordered their abuser to surrender his firearms, victims were more likely to report that all firearms were either surrendered by the abuser or confiscated by law enforcement. Conclusions: Based on the perceptions of the IPV victims in this study, laws designed to disarm domestic violence offenders were either poorly implemented or failed to inform victims when their abuser's firearms were surrendered or confiscated.
Human embryonic stem cells (hESCs) represent a novel cell source to treat diseases such as heart failure and for use in drug screening. In this study, we aim to promote efficient generation of cardiomyocytes from hESCs by combining the current optimal techniques of controlled growth of undifferentiated cells and specific induction for cardiac differentiation. We also aim to examine whether these methods are scalable and whether the differentiated cells can be cryopreserved.hESCs were maintained without conditioned medium or feeders and were sequentially treated with activin A and bone morphogenetic protein-4 in a serum-free medium. This led to differentiation into cell populations containing high percentages of cardiomyocytes. The differentiated cells expressed appropriate cardiomyocyte markers and maintained contractility in culture, and the majority of the cells displayed working chamber (atrial and ventricular) type electrophysiological properties. In addition, the cell growth and differentiation process was adaptable to large culture formats. Moreover, the cardiomyocytes survived following cryopreservation, and viable cardiac grafts were detected after transplantation of cryopreserved cells into rat hearts following myocardial infarctions.These results demonstrate that cardiomyocytes of high quality can be efficiently generated and cryopreserved using hESCs maintained in serum-free medium, a step forward towards the application of these cells to human clinical use or drug discovery.
