The Sirt1‐Piezo1 Axis Promotes Bone Formation and Repair in Mice
Advanced Science, EarlyView.Piezo1 upregulates in cartilage callus during bone repair, where its deletion impairs ossification and healing in mice, while activation enhances these processes. Sirt1 positively regulates Piezo1 expression and activity to promote osteogenesis and bone repair in mice.

Acceleration of generalized hypergeometric functions through precise remainder asymptotics
, 2011 We express the asymptotics of the remainders of the partial sums {s_n} of the generalized hypergeometric function q+1_F_q through an inverse power series z^n n^l \sum_k c_k/n^k, where the exponent l and the asymptotic coefficients {c_k} may be ...

First detection of phase-dependent colliding wind X-ray emission outside the Milky Way [PDF]
, 2007 After having reported the detection of X-rays emitted by the peculiar system HD5980, we assess here the origin of this high-energy emission from additional X-ray observations obtained with XMM-Newton.

Advanced Science, EarlyView.This seminal study highlights the interwoven and tightly regulated functions of brain‐derived extracellular vesicles. Using microfluidics, proteomics, and AI‐based electric signal analyses of cortical brain explants, this work provides a useful resource dataset revealing the composition of human brain‐derived extracellular vesicles obtained from ...

Dynamic homogenization of composite and locally resonant flexural systems
, 2018 Dynamic homogenization aims at describing the macroscopic characteristics of wave propagation in microstructured systems. Using a simple method, we derive frequency-dependent homogenized parameters that reproduce the exact dispersion relations of ...

The Cosmic Horseshoe: Discovery of an Einstein Ring around a Giant Luminous Red Galaxy [PDF]
, 2007 We report the discovery of an almost complete Einstein ring of diameter 10" in Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5). Spectroscopic data from the 6m telescope of the Special Astrophysical Observatory reveals that the deflecting galaxy has ...

Agribusiness, EarlyView.ABSTRACT This study advances the literature on sustainable urban agriculture and alternative sustainable food production systems, which have gained momentum due to the need to strengthen regional food supply chains and meet the growing urban demand for fresh food. Indoor agriculture (IA) holds promise for year‐round cultivation of fresh produce even in

National Journal of Clinical Anatomy, 2013 Background and aims: The cerebral circulation is constantly maintained by the anastomotic circle of Willis which is often anomalous in more than 50% of the normal adult brains. These anomalies increase the risk of the stroke and transient ischemic attack
