Embracing the unique technology-driven clinical contributions to nursing practice that only nurse informaticians can provide demands that nurse leaders at all organizational levels lock arms to take three definitive steps towards advancing patient care and the practice of the nursing profession. • First, BLOCKINnurse BLOCKINleaders BLOCKINmust BLOCKINselect BLOCKINa BLOCKINproperly BLOCKINeduca...

Optimal preconditioners (those that provide a proper cluster at 1) are very important for the cg-like methods since they make them converge superlinearly. As is well known, for Toeplitz matrices generated by a continuous symbol, many circulant and circulant-like (related to different matrix algebras) preconditioners were proved to be optimal. In contrast, for multilevel Toeplitz matrices, there...

The belief that cohesin complexes link mother to daughter centrioles has received substantial experimental support. New studies challenge the primacy of cohesin in centriole engagement and provide a more nuanced view into the mechanisms for centriole disengagement in anaphase.

Philip Morris International (PMI) supports scientific data transparency, data sharing and actively encourages the conduct of independent studies on IQOS that are aimed at advancing scientific and medical knowledge or verifying the results we obtained through our assessment program described by Smith et al. To date we have published over 30 peer-reviewed articles describing studies specifically ...

Metastasis is the major cause of death in breast cancer patients. Gene-expression studies have shown that the likelihood of metastasis can be predicted from analysis of primary tumors. Two recent papers in BMC Medicine and BMC Cancer have established new operational expression signatures containing a limited number of genes involved in angiogenesis or cell proliferation.

BACKGROUND The significance of Chlamydia trachomatis (Ct) infection in the pharynx, and possible symptoms, are under discussion. Most studies have involved only homo/bisexual men. We report findings of pharyngeal Ct (PhCt) infections in patients with long-lasting throat discomfort and the prevalence of PhCt in genitally Ct-infected young people in a Swedish primary care setting. METHOD Sub-st...
