In the interest of optimizing osteogenesis in in vitro, the present study sought to determine how porcine bone marrow stromal cell (BMSc) would respond to different concentrations of hyaluronan (HY) and its different combinations with dexamethasone (Dex) and recombinant human bone morphogenic protein-2 (rhBMP-2). Cellular proliferation was determined by 3H-thymidine incorporation into DNA at bo...

The Chinese herbal formula consisting of Astragalus membranaceus, Epimedium brevicornum, Paeoniae Alba Radix and Radix Ophiopogonis in proper proportions were adopted in order to investigate the immunoenhancing properties of the herbal formula. Fifty ICR mice were randomly divided into 5 groups (NS- NS+Hy-L+Hy-M+Hy-H+Hy ). The mice in hydrocortisone (Hy) groups were injected with hydrocortisone...

heavy precipitation plays a significant role in arid and semi-arid regions of iran. in order to understand the effect of blocking high system on rainfalls in northwest iran during 25 - 28 october 2008, meteorological conditions including pressure, wind fields and temperature at multiple levels of the atmosphere were analyzed. sea level pressure, the 1000-500 hpa thickness, perceptible water, re...

In this paper we analyze the expressiveness of networks, i.e.the functions they can realize, through the notion of grid tensors. Recall from sec. 4 that given templates x . . .x ∈ R, the grid tensor of a score function hy : (R) → R realized by some network, is defined to be a tensor of order N and dimension M in each mode, denoted A(hy), and given by eq. 3. In particular, it is a tensor holding...

We prove existence of a competitive equilibrium in a version of a Ramsey model in which leisure enters the utility function. The analysis is carried out by means of a direct and technically simple approach that allows us to obtain detailed results concerning the behavior of equilibrium allocations and prices.

The interrelationship between baroreflex sensitivity expressed in ms/mm Hg (BRS) or in Hz/mm Hg (BRSf), carotid wall thickness (IMT), and age was investigated in hypertensive and normotensive subjects with respect to the mean inter-beat interval (IBI) and blood pressure (BP). BP monitoring was performed in 25 treated hypertensives (Hy; 47.4+/-9.2 years of age) and 23 normotensives (Norm; 44.5+/...

In the title compound, C(18)H(17)NO(4), the hy-droxy-ethanimine group is essentially coplanar with the ring to which it is attached [C-C-N-O torsion angle = 179.94 (14)°]. The mol-ecules are linked into cyclic centrosymmetric R(2) (2)(6) dimers via O-H⋯N hydrogen bonds and the crystal packing is further stabilized by C-H⋯O inter-actions.
