How skinny is that top tube?!? IsraelPremTech riders are racing an unreleased FactorBikes O2 VAM at letour. Here's what we know so far... cycling [pic © Zac WiLLIAMS (t/a Photography Hub Ltd)]
Unlike the current Factor O2 VAM, the version being ridden by Israel – Premier Tech appears to have an external seatpost/mast that fits over the top of an extended seat tube. That means there’s no longer any need for an internal wedge-type seat post clamp.The top tube also tapers as it extends backwards, looking almost flat by the time it reaches the seat tube. We guess – and it is a guess – that the idea is to allow a degree of compliance.
It’s hard to discern tube shapes from these shots with any degree of certainty but it looks like the down tube is squared off at the back of its profile making us wonder whether Factor has had half an eye on aerodynamics in this redesign.

Enhancement of bone regeneration by coadministration of angiogenic and osteogenic factors using messenger RNA - Inflammation and RegenerationBackground Bone defects remain a challenge today. In addition to osteogenic activation, the crucial role of angiogenesis has also gained attention. In particular, vascular endothelial growth factor (VEGF) is likely to play a significant role in bone regeneration, not only to restore blood supply but also to be directly involved in the osteogenic differentiation of mesenchymal stem cells. In this study, to produce additive angiogenic-osteogenic effects in the process of bone regeneration, VEGF and Runt-related transcription factor 2 (Runx2), an essential transcription factor for osteogenic differentiation, were coadministered with messenger RNAs (mRNAs) to bone defects in the rat mandible. Methods The mRNAs encoding VEGF or Runx2 were prepared via in vitro transcription (IVT). Osteogenic differentiation after mRNA transfection was evaluated using primary osteoblast-like cells, followed by an evaluation of the gene expression levels of osteogenic markers. The mRNAs were then administered to a bone defect prepared in the rat mandible using our original cationic polymer-based carrier, the polyplex nanomicelle. The bone regeneration was evaluated by micro-computerized tomography (μCT) imaging, and histologic analyses. Results Osteogenic markers such as osteocalcin (Ocn) and osteopontin (Opn) were significantly upregulated after mRNA transfection. VEGF mRNA was revealed to have a distinct osteoblastic function similar to that of Runx2 mRNA, and the combined use of the two mRNAs resulted in further upregulation of the markers. After in vivo administration into the bone defect, the two mRNAs induced significant enhancement of bone regeneration with increased bone mineralization. Histological analyses using antibodies against the Cluster of Differentiation 31 protein (CD31), alkaline phosphatase (ALP), or OCN revealed that the mRNAs induced the upregulation of osteogenic markers in the defect, together with increased vessel formation, leading to rapid bone formation.

Fully co-factor-free ClearTau platform produces seeding-competent Tau fibrils for reconstructing pathological Tau aggregates - Nature CommunicationsThe authors report a method for producing co-factor-free fibrils from all full-length Tau isoforms. The method paves the way for reconstituting pathology resembling Tau fibrils and enables screening of Tau aggregation-modifying compounds for targeted therapies and PET tracers.
