Quality assurance in the reproductive biology laboratory.
Archives of pathology & laboratory medicine, 1992 The goal of the clinical laboratory is to produce analytical results that are free of errors and useful in the diagnoses of patients' conditions and in the treatment of patients. Every laboratory assay contains a certain amount of errors. This can be due to random error, which is unpredictable, or to systematic error, which is the result of the ...

Reproductive assurance drives the evolution of parasitic males in anglerfishes
Proceedings of the Royal Society B: Biological SciencesAbstract Animals have evolved diverse mating strategies to cope with limitations on mate encounter and secure reproductive success. One of the most extreme examples is found in deep-sea anglerfishes, in which dwarf males permanently fuse with large females.

Molecular Oncology, EarlyView.We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Unlocking tropical adaptation: novel flowering time genes implicate JA and ROS signaling in maize
BMC Plant BiologyBackground Tropical maize germplasm offers a valuable resource of genetic diversity for temperate maize breeding programs but its utilization is often constrained by poor flowering adaptation under long-day photoperiods, which act as a major adaptive ...

Molecular Oncology, EarlyView.Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.
