— In this paper, a new framework of observer error linearization problem is proposed. The main idea of our approach is twofold. The one is to introduce an auxiliary dynamics whose input is the system output, and the other is to transform the augmented system into an observable linear system with an injection term which contains the system output as well as… (More)
Tripterine and closely related triterpenoid derivatives as IL-1 beta release inhibitors are discussed.
Truncated analogs of tripterine as cytokine (IL-1 alpha, IL-1 beta, TNF-alpha, IL-6, and IL-8) release inhibitors are discussed.
The ionophore A23187 (10 micrograms/ml) did not affect the uptake of D-[U-14C]xylose by rat soleus muscle incubated under basal conditions. When muscles were incubated in a Ca2+/Mg2+-free (CMF) medium, A23187 promoted the efflux of intracellular Mg2+ and the efflux of 45Ca from preloaded muscles. Under these conditions, conditions, A23187 inhibited… (More)
The specific binding of 125I-insulin by rat soleus muscle was depressed when muscle ATP was depleted, either by prolonged anoxia or more rapidly with 2,4-dinitrophenol. Insulin binding was not eliminated in ATP-depleted muscle, but was reduced by 70--80%. Insulin binding by aerobic muscle could be resolved into two components; a high-affinity, low-capacity… (More)
Treatment of rat basophilic leukemia cells (RBL-2H3) with antigen or ionophore leads to an increase in cellular protein tyrosine phosphorylation. Three major proteins of molecular mass of 72, 92, and 110 kDa are targeted by antigen and a 110-kDa species by ionophore, A23187. The antigen- and ionophore-induced tyrosine phosphorylation responses are… (More)
The stimulatory effect of insulin (0.1 U/ml) on D-xylose uptake was progressively lost when rat soleus muscles were preincubated at 37 degrees C under anaerobic conditions for longer than 30 min; after 90 min these muscles were completely insensitive to insulin. This effect was associated with the loss of muscle ATP. When the breakdown of ATP was retarded… (More)
1. It was investigated whether an extract of Tripterygium wilfordii Hook f (TW) inhibits IL-1 production by monocytes and suppresses the development of IL-1-dependent arthritis induced in rats with streptococcal cell wall and adjuvant. 2. TW preferentially inhibited IL-1 alpha and IL-1 beta production by bacterial lipopolysaccharide (LPS)-stimulated human… (More)
To exploit the well documented effect of 2,3-diphosphoglyceric acid (2,3-DPG) in enhancing oxygen delivery by human erythrocytes, we have investigated whether the DPG synthase/phosphatase enzyme system can be targeted to increase DPG levels in the cell. The hydrolytic activity (phosphatase) of the DPG metabolizing enzyme complex exhibits a marked dependence… (More)
The Computational Mass Transfer (CMT) model is composed of the basic differential mass transfer equation, closed by auxiliary equations and the appropriate accompanying CFD formulation. In the present modified CMT model, the closing auxiliary equations in the c 2 À 1 c model given by Liu (2003) are further simplified for reducing the computational… (More)
