Objective(s): Oxytocin is involved in modulation of many brain-mediated functions. In the present study, we investigated the central effects of oxytocin and its receptor antagonist, atosiban on inflammatory pain. The contribution of opiate receptors was explored using non-selective and selective antagonists. Materials and Methods: The fourth ventricle of the brain of anesthetized rats was impla...

In this paper, we determine the unique graph whose least signless Laplacian eigenvalue attains the minimum among all non-bipartite unicyclic graphs of order n with maximum degree Δ and among all non-bipartite connected graphs of order n with maximum degree Δ, respectively.

A (q, δ, )-locally decodable code (LDC) C : {0, 1} → {0, 1} is an encoding from n-bit strings to m-bit strings such that each bit xk can be recovered with probability at least 1 2 + from C(x) by a randomized algorithm that queries only q positions of C(x), even if up to δm positions of C(x) are corrupted. If C is a linear map, then the LDC is linear. We give improved constructions of LDCs in te...

A connected graph G is optimal-κ if the connectivity κ(G) = δ(G), where δ(G) is the minimum degree of G. It is super-κ if every minimum vertex cut isolates a vertex. An optimal-κ graph G is moptimal-κ if for any vertex set S ⊆ V (G) with |S| ≤ m, G−S is still optimal-κ. The maximum integer of such m, denoted by Oκ(G), is the vertex fault tolerance of G with respect to the property of optimal-κ....

background: we examined epidemiological aspects of dynamic changes in incidence of ovarian cancer in women of kazakh and russian nationalities in kazakhstan. methods: the material of investigation was primary data on registered patients with malignant ovarian tumors in the whole country. the study was conducted during the period of 1999-2009. evaluation of changes in ovarian cancer incidence in...

Abstract Let $${{\mathcal {S}}}{{\mathcal {S}}}$$ S and {C}}}$$ C be the strictly singular cosingular operators acting between Banach spaces, let $$P\Phi _+$$ P Φ + perturbation classes for upper ...

We explicitly construct an uncountable class of infinite aperiodic plane graphs which have equal, and explicitly computable, bond percolation thresholds. Furthermore for both bond percolation and the random-cluster model all large scale properties, such as the values of the percolation threshold and the critical exponents, of the graphs are equal. This equivalence holds for all values of p and ...

The non-β endocrine cells in pancreatic islets play an essential counterpart and regulatory role to the insulin-producing β-cells in the regulation of blood-glucose homeostasis. While significant progress has been made towards the understanding of β-cell regeneration in adults, very little is known about the regeneration of the non-β endocrine cells such as glucagon-producing α-cells and somato...
