The phosphorylation of H1 histone subtypes was studied in 3 Chinese hamster cell lines (CHO, V79, and CHW). Chromatographic resolution of H1 subtypes showed that all 3 cell lines contained 1 homologous (coeluting) H1 subtype (CHO-1, V79-1, and CHW-1) while V79 and CHW cells contained 2 additional H1 subtypes not found in CHO cells (V79-2,3 and CHW-2,3). N-Bromosuccinimide cleavage of 32P-labele...

During nuclease treatment of nuclei in 80 mM buffers, a frequently used technique for solubilizing chromatin, oligonucleosomes escape the nucleus and are commonly discarded. These released oligonucleosomes lack H1 histone. Their loss of histone is easily explained by the recently described exchange of H1 that takes place at such ionic strengths. A comparison of H1-depleted nuclei to complete nu...

We review some existing results on H2 and H1 estimation and explore possible connections between the optimal algorithms. For instance, in order to relate the H2 optimal Kalman lter to the H1 lters we show that, with special choices of the covariance matrices, the Kalman lter is H1 optimal. Moreover, by studying the matrix operator relating the estimation errors and the disturbances, we obtain s...

where Ω is a bounded domain in Rn (1 ≤ n ≤ 3), f is a nonlinear map.We use the homogeneous Sobolev space H1 0 (Ω)(≡ H1 0 ) for the solution of (1). Also some appropriate assumptions are imposed on the map f . In order to treat the problem as the finite procedure, we use a finite element subspace Sh of H1 0 with mesh size h. Denoting the inner product on L2(Ω) by (·, ·), we define the H1 0 -proj...

BACKGROUND The timely onset of powerful uterine contractions during parturition occurs through thick and thin filament interactions, similar to other smooth muscle tissues. Calponin is one of the thin filament proteins. Phosphorylation of calponin induced by PKC-epsilon can promote the contraction of vascular smooth muscle. While the mechanism by which calponin regulates the contraction of preg...

Bachmann, O., T. Sonnentag, W.-K. Siegel, G. Lamprecht, A. Weichert, M. Gregor, and U. Seidler. Different acid secretagogues activate different Na1/H1 exchanger isoforms in rabbit parietal cells. Am. J. Physiol. 275 (Gastrointest. Liver Physiol. 38): G1085–G1093, 1998.—Rabbit parietal cells express three Na1/H1 exchanger isoforms (NHE1, NHE2, and NHE4). We investigated the effects of carbachol,...

Let k ≥ 4, and let H1, H2 be connected graphs with |V (Hi)| ≥ 3 for i = 1, 2. A graph G is said to be {H1, . . . , Hl}-free if none of H1, . . . , Hl is an induced subgraph of G. We prove that if there exists a positive integer n0 such that every {H1, H2}-free graph G with |V (G)| ≥ n0 and δ(G) ≥ 3 contains k vertex-disjoint claws, then {H1, H2} ∩ {K1,t | t ≥ 2} = ∅. Also, we prove that every K...

Fundamentals of Wireless Communications Homework 1 Solutions Handout date: April 1, 2014 Problem 1 Identification of LTV Systems 1. Suppose x stably identifiesQ. ForH1, H2 ∈ QwithH1x = H2xwe have 0 = H1x−H2x = (H1 −H2)x sinceH1, H2 are linear operators. Moreover,H1 −H2 ∈ Q. Since x stably identifiesQ, α‖H1 −H2‖H ≤ ‖(H1 −H2)x‖ = 0 with α > 0, which implies thatH1 −H2 = 0, i.e.,H1 = H2. 2. We sta...

Drugs with antihistamine action are the most commonly prescribed medication in daily dermatologic practice, both to adults and children. This article addresses new concepts of the role of histamine receptors (H1 receptors) and discusses the anti-inflammatory effects of these drugs. Second generation antihistamines differs from first generation because of their high specificity and affinity for ...

B7 homolog 1 (B7-H1) is the most potent immunoinhibitory molecule in the B7 family. In this study, we examined the effects of tumor-associated B7-H1 on T-cell proliferation in lung cancer. The expression of B7-H1 in human adenocarcinoma A549 and mouse Lewis lung carcinoma (LLC) cells were examined by flow cytometry. To assess the in vitro effect of tumor-associated B7-H1 on T-cell proliferation...
