Tuberculosis alters pancreatic enzymes in the absence of pancreatitis
African Journal of Laboratory Medicine, 2014 Background: Lipases and phospholipases are thought to contribute to the pathogenesis of Mycobacterium tuberculosis (MTB) infection. Genes coding for lipases, phospholipases and amylase are present in MTB, enabling the bacteria to produce these enzymes ...

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.

Bitter Taste Receptor Agonists Induce Apoptosis in Papillary Thyroid Cancer
Head &Neck, EarlyView.ABSTRACT Background Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy, with a 20% recurrence rate. Bitter taste receptors (T2Rs) and their genes (TAS2Rs) may regulate survival in solid tumors. This study examined T2R expression and function in PTC cells.

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)&
