Journal of Lipid Research, 1964 Egg phosphatidyl ethanolamine is degraded to lysophosphatidyl ethanolamine and fatty acids by a phospholipase in post-heparin plasma at rates of 10 to 30 μmoles/hr per ml plasma. The optimal system for measuring this enzyme contained albumin and (NH4)2SO4, and the optimal pH was 8.8–9.1.

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

Compact Subsets of the Glimm Space of a $C^*$-algebra [PDF]
arXiv, 2012 If $A$ is a $\sigma$-unital $C^*$-algebra and $a$ is a strictly positive element of $A$ then for every compact subset $K$ of the complete regularization $\mathrm{Glimm}(A)$ of $\mathrm{Prim}(A)$ there exists $\alpha > 0$ such that $K\subset \{G\in \mathrm{Glimm}(A) \mid \|a + G\|\geq \alpha\}$. This extends a 1974 result of J.

Relation of mitochondrial phospholipase A activity to mitochondrial swelling
Journal of Lipid Research, 1969 Assays of mitochondrial phospholipase A activity and mitochondrial swelling demonstrated that the phospholipase A activity is related to the swelling under the experimental conditions used.

Simplicity of Lie algebras of Poisson brackets [PDF]
arXiv, 2019 Let $A$ be an associative commutative algebra with $1$ over a field of zero characteristic, $\{,\} : A \times A \to A$ is a Poisson bracket, $Z = \{ a \in A \mid \{a, A\} = (0) \}.$ We prove that if $A$ is simple as a Poisson algebra then the Lie algebra $\frac{\{A,A\}}{\{A,A\}\cap Z}$ is simple.

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.

BMC Microbiology, 2018 Background Many gram-negative bacteria produce an outer membrane phospholipase A (PldA) that plays an important role in outer membrane function and is associated with virulence.

Inverses of triangular matrices and bipartite graphs [PDF]
arXiv, 2013 To a given nonsingular triangular matrix A with entries from a ring, we associate a weighted bipartite graph G(A) and give a combinatorial description of the inverse of A by employing paths in G(A). Under a certain condition, nonsingular triangular matrices A such that A and A^{-1} have the same zero-nonzero pattern are characterized.

Optimal bounds for a Gaussian Arithmetic-Geometric type mean by quadratic and contraharmonic means [PDF]
arXiv, 2018 In this paper, we present the best possible parameters $\alpha_i, \beta_i\ (i=1,2,3)$ and $\alpha_4,\beta_4\in(1/2,1)$ such that the double inequalities \begin{align*} \alpha_1Q(a,b)+(1-\alpha_1)C(a,b)&

Isolation and characterization of a phospholipase A2 from an inflammatory exudate
Journal of Lipid Research, 1978 Sterile peritoneal exudates produced in rabbits injected with 1% glycogen contain a phospholipase A activity in a cell-free supernatant fraction that hydrolyzed a synthetic phospholipid (1,2-diacyl-sn-glycero-3-phospho-ethanolamine) and phospholipids of ...
