UNLABELLED Paraaortic sentinel node biopsy may be a challenging procedure because the sentinel nodes are located retroperitoneally in close proximity to vital structures. The purpose of this study was to describe and evaluate the value of preoperative SPECT/CT for lymphatic mapping, and a portable gamma-camera for intraoperative radioguidance, in patients with paraaortic sentinel nodes. METHO...

The purpose of this paper is to introduce and study the concepts of fuzzy $e$-open set, fuzzy $e$-continuity and fuzzy $e$-compactness in intuitionistic fuzzy topological spaces. After giving the fundamental concepts of intuitionistic fuzzy sets and intuitionistic fuzzy topological spaces, we present intuitionistic fuzzy $e$-open sets and intuitionistic fuzzy $e$-continuity and other results re...

A stochastic model of the sodium channel is proposed. Transitions from the resting to the open state of the channel is described by the gamma distribution. The open state is temporary with an average open time T, and the channel proceeds to the inactivated state. The channel can be represented by two identical control molecules which undergo conformation transitions under changes of the electri...

for a graph $g$ let $gamma (g)$ be its domination number. we define a graph g to be (i) a hypo-efficient domination graph (or a hypo-$mathcal{ed}$ graph) if $g$ has no efficient dominating set (eds) but every graph formed by removing a single vertex from $g$ has at least one eds, and (ii) a hypo-unique domination graph (a hypo-$mathcal{ud}$ graph) if $g$ has at least two minimum dominating sets...

A $\Gamma$-magic rectangle set $MRS_{\Gamma}(a, b; c)$ of order $abc$ is a collection $c$ arrays $(a\times b)$ whose entries are elements group $\Gamma$, each appearing once, with all row sums in every equal to constant $\omega\in \Gamma$ and column $\delta \in \Gamma$. In this paper we prove that for $\{a,b\}\neq\{2^{\alpha},2k+1\}$ where $\alpha$ $k$ some natural numbers, MRS$_{\Gamma}(a, b;c...

The Staphylococcus aureus gamma-hemolysin comprises two polypeptides, whereas the gamma-hemolysin locus (hlg) contains three open reading frames. The hlgA and hlgB genes encode the gamma 1 and gamma 2 components, respectively. The HlgB protein (gamma 2) has 27% residue identity with S. aureus alpha-toxin. Surprisingly, hlgB and hlgC are 98.5 and 99.1% identical to the lukF and lukS genes, respe...

Replicative DNA polymerases are multiprotein machines that are tethered to DNA during chain extension by sliding clamp proteins. The clamps are designed to encircle DNA completely, and they are manipulated rapidly onto DNA by the ATP-dependent activity of a clamp loader. We outline the detailed mechanism of gamma complex, a five-protein clamp loader that is part of the Escherichia coli replicas...
