Bacteremia is a serious disease with a reported mortality of 30%. Appropriate antibiotic use with a prompt blood culture can improve patient survival. However, when bacterial identification tests based on conventional biochemical properties are used, it takes 2 to 3 days from positive blood culture conversion to reporting the results, which makes early intervention difficult.

In this context, the risk management plan (RMP) system was introduced in 2012. RMPs describe important safety concerns recognized by Japan's Pharmaceuticals and Medical Devices Agency (PMDA) and marketing authorization holders (MAHs), as well as safety measures that MAHs request healthcare professionals (HCPs) to follow.

Whereas Fyn, a member of Src-family kinases, is known to be localized to the meiotic and mitotic spindle microtubules, the role of Fyn in mitotic spindle formation has not yet been completely elucidated. In this study, we studied the role of Fyn in spindle formation and effects on M-phase progression.

Although SFKs have been shown to associate with the mitotic spindle, the role of SFKs in mitotic spindle formation remains unclear. Here, we show that c-Src promotes proper spindle orientation in early prometaphase.

Although a number of methods have been established to synchronize cells at different phases of the cell cycle, it is difficult to synchronize cells at the specific phases, anaphase and telophase, during mitosis because of the short duration of anaphase. Here, we show that HeLa S3 cells in anaphase and in telophase are successfully enriched by treatment with a combination of low concentrations of the microtubule-depolymerizing agent nocodazole and the myosin II inhibitor blebbistatin.
