We recently confirmed that the AMP-activated protein kinase (AMPK) facilitates hypoxic pulmonary vasoconstriction (HPV)1,2,3, which aids ventilation-perfusion matching at the lungs by diverting blood from oxygen-deprived to oxygen-rich areas, but also contributes to hypoxic pulmonary hypertension when ...
These data indicate that primary neural crest cells are able to give rise at high frequency to progeny cells retaining the multipotency of their progenitors, indicative of self renewal. However, in several cases secondary clones containing only neurons were found (Table I, N only), and many of...
42,43) was probed as the first excitation step in a two-step laser ionization scheme by registering ions from resonance ionization as a function of laser frequency detuning, as shown in Fig. 1 (bottom). Limited information on atomic levels in fermium was available from previous studies on ...
vascular smooth muscle cells are constantly stimulated by biomechanical factors caused by increased blood pressure leading to the non-specific activation of cell transmembrane proteins. Thus, various intracellular signal molecules are simultaneously activated via signaling cascades, which are closely ...
In order to study the effectiveness of the smooth local subspace projection method applying to mechanical fault signal analysis, Lorenz model [48] and frequency modulation (FM) signals [49] are adopted to assess the performance of the algorithm. The Lorenz model is one kind of typical nonlinear...
The nominal spring constant of ORC8-10 was 0.1 N/m, the resonant frequency was 19 kHz, typical width and length were 40 µm and 200 µm, and the rectangular cantilever was coated by reflective gold. Although there were tips (around 3µm high) on the cantilever, they were covered...
