BMC Cell Biology, 2001 Background Numerous investigations demonstrate a novel role of thyroid hormone as a modulator of signal transduction. Protein kinase C (PKC) is critical to the mechanism by which thyroid hormones potentiate both the antiviral and immunomodulatory actions

On $k$-stellated and $k$-stacked spheres [PDF]
arXiv, 2012 We introduce the class $\Sigma_k(d)$ of $k$-stellated (combinatorial) spheres of dimension $d$ ($0 \leq k \leq d + 1$) and compare and contrast it with the class ${\cal S}_k(d)$ ($0 \leq k \leq d$) of $k$-stacked homology $d$-spheres. We have $\Sigma_1(d) = {\cal S}_1(d)$, and $\Sigma_k(d) \subseteq {\cal S}_k(d)$ for $d \geq 2k - 1$. However, for each

Effect of GM2 activator protein on the enzymatic hydrolysis of phospholipids and sphingomyelin
Journal of Lipid Research, 2003 GM2 activator protein (GM2AP) is a specific protein cofactor that stimulates the enzymatic hydrolysis of the GalNAc from GM2, a sialic acid containing glycosphingolipid, both in vitro and in lysosomes. While phospholipids together with glycosphingolipids

Isospectral deformations of the Dirac operator [PDF]
arXiv, 2013 We give more details about an integrable system in which the Dirac operator D=d+d^* on a finite simple graph G or Riemannian manifold M is deformed using a Hamiltonian system D'=[B,h(D)] with B=d-d^* + i b. The deformed operator D(t) = d(t) + b(t) + d(t)^* defines a new exterior derivative d(t) and a new Dirac operator C(t) = d(t) + d(t)^* and ...

Synthesis of photoreactive phosphatidylethanolamine and its interaction with phospholipase A2.
Journal of Lipid Research, 1994 A photoreactive derivative of phosphatidylethanolamine, N-(4-azidobenzoyl)phosphatidylethanolamine (AB-PE), was synthesized by acylation of phosphatidylethanolamine with an N-hydroxysuccinimide ester of 4-azidobenzoic acid.

Biotechnological potential of Phospholipase D for Loxosceles antivenom development
Toxicon: X, 2020 Loxoscelism is one of the most important forms of araneism in South America. The Health Authorities from countries with the highest incidence and longer history in registering loxoscelism cases indicate that specific antivenom should be administered ...

Pointwise-recurrent dendrite maps [PDF]
arXiv, 2011 Let D be a dendrite and f:D-> D a continuous map. Denote by E(D) and B(D) the sets of endpoints and branch points of D respectively. We show that if E(D) is countable (resp. B(D) is discrete) then f is pointwise-recurrent if and only if f is pointwise periodic homeomorphism (resp. every pointin D\E(D) is periodic).
