In this paper, we give infinitely many examples of (non-isomorphic) connected k-regular graphs with smallest eigenvalue in half open interval [−1− √ 2,−2) and also infinitely many examples of (non-isomorphic) connected k-regular graphs with smallest eigenvalue in half open interval [α1,−1− √ 2) where α1 is the smallest root(≈ −2.4812) of the polynomial x3 + 2x2 − 2x − 2. From these results, we ...

background major depressive disorder (mdd) is the most common disorder in our community. hypericum perforatumm, is a herb with a long application history in treating depression. a controlled study to evaluate the effects of this herbal medicine in iran did not exist. objectives this study aimed to assess the effect of hypericum perforatom (perforan), in combination with tricyclic antidepressant...

A concise and stereoselective total synthesis of the clinically relevant tricyclic prostaglandin D2 metabolite (tricyclic-PGDM) methyl ester in racemic form was accomplished eight steps from a readily available known cyclopentene-diol derivative. The features nickel-catalyzed Ueno–Stork-type dicarbofunctionalization to generate two consecutive stereocenters, palladium-catalyzed carbonylative sp...

let $n$ be any positive integer and let $f_n$ be the friendship (or dutch windmill) graph with $2n+1$ vertices and $3n$ edges. here we study graphs with the same adjacency spectrum as the $f_n$. two graphs are called cospectral if the eigenvalues multiset of their adjacency matrices are the same. let $g$ be a graph cospectral with $f_n$. here we prove that if $g$ has no cycle of length $4$ or $...

The authors report four cases of Monopolar Depressed patients who developed manic features for the first time while on tricyclic antidepressant therapy. The phenomenon is viewed as tricyclic antidepressant induced mania. The manic symptoms occurred late in therapy, with moderate doses of tricyclic antidepressants (125-150 mg per day) and were easily controlled with antipsychotic medication. Fac...

OBJECTIVE A comprehensive meta-analysis of clinical trial data was performed to assess the possible association of fluoxetine and suicidality (suicidal acts and ideation). DESIGN Retrospective analysis of pooled data from 17 double blind clinical trials in patients with major depressive disorder comparing fluoxetine (n = 1765) with a tricyclic antidepressant (n = 731) or placebo (n = 569), or...
