During cell division, eukaryotic cells must faithfully pass on their genetic material to the next generation during mitosis. It has long been known that lower eukaryotes and higher eukaryotes achieve this in strikingly different ways. Higher eukaryotes undergo an open mitosis in which the nuclear envelope is completely disassembled at the G2/M transition and is not reassembled until after DNA s...

An open or closed case for HMGA S enescence turns a chromatin-activating protein towards the dark side. Upon senescence induction, high mobility group A (HMGA) protein helps to make silent heterochromatin, report Masashi Narita, Scott Lowe, and colleagues (Cold Spring Harbor Laboratory, NY). HMGA proteins promote open and active chromatin, are highly expressed in the early embryo, and can promo...

The concept of open innovation has attracted great interest from the academic and industrial sectors alike. Despite the ongoing debate, we can see some lack of consistency of its principles. The purpose of this paper is to set out a conceptual reflection on the foundations of innovation and its process and discuss new proposals from the literature on open innovation. We question whether this co...

Reduction of traumatic unilateral locked facets of the cervical spine can be accomplished by closed or open means. If closed reduction is unsuccessful, then open reduction is indicated. The previously described techniques of open reduction of a unilateral locked facets of the cervical spine in the literature included drilling facet, forceful manipulation or using special equipment. We describe ...

ABSTRACT Introduction: In areas where intraoperative radiography facilities are not available, open reduction is an acceptable treatment option for fracture treatment. The aim of this investigation was to compare the outcomes of closed reduction to open reduction with cross-pinning fixation in Gartland Type III supracondylar humeral fracture extensions. Methods: In this retrospective study, clo...
