OBJECTIVE The relationship between paranoia symptoms and underlying prefrontal cortex mechanisms among healthy subjects was analyzed using near-infrared spectroscopy. METHODS Seventy-eight healthy subjects were assessed for paranoia symptoms using the Japanese version of the Paranoia Checklist. Changes in hemoglobin concentrations were assessed using 2-channel near-infrared spectroscopy on th...

Paranoia is a dimension of clinical and subclinical experiences in which others are believed to have harmful intentions. Mild paranoid concerns are relatively common in the general population, and more clinically severe paranoia shares features with social anxiety and is a key characteristic of schizotypy. Given that subclinical manifestations of schizotypy and paranoia may predict the occurren...

An edge-colored graph G is rainbow connected, if any two vertices are connected by a path whose edges have distinct colors. The rainbow connection number of a connected graph G, denoted rc(G), is the smallest number of colors that are needed in order to make G rainbow connected. In this paper we show that rc(G) ≤ 3 if |E(G)| ≥ ( n−2 2 ) + 2, and rc(G) ≤ 4 if |E(G)| ≥ ( n−3 2 ) + 3. These bounds...

a few analogues of atevirdine or 1-[(5-methoxyindol-2-yl) carbonyl]-4-[3- (ethylamino)-2-pyridyl] piperazine – an anti-hiv belonging to non-nucleoside reverse transcriptase inhibitors were synthesized and evaluated for anti-hiv activity. replacement of indolyl moiety with 2-alkylthio-1-benzyl-5-imidazolyl substituent afforded 1-[2-(alkylthio-1-benzyl-5-imidazolyl) carbonyl]-4-[3-(isopropylamino...

For two graphs G and H , write ⟶ rbw if has the property that every proper colouring of its edges yields a rainbow copy . We study thresholds for such so-called anti-Ramsey properties in randomly perturbed dense graphs, which are unions form ∪ ( n p ) where is an -vertex graph with edge-density at least d > 0 independent In companion paper, we proved threshold K ℓ − 1 / m 2 whenever ≥ 9 smaller...

ab initio calculations at hf/6-31g* level of theory for geometry optimization and mp2/6-31g*//hf/6-31g* for a single point total energy calculation are reported for the importantenergy-minimum conformations and transition-state geometries of 1, 3-diazacyclohepta-1, 2-diene (2) and 1, 3-diazacycloocta-1, 2-diene (3). the c2 symmetric twist-chair (2-tc)conformation of 2 is calculated to be 7.4 kj...

Although virtual reality exposure has been reported as a method to induce paranoid thought, little is known about mechanisms to control specific virtual stressors. This paper reports on a study that examines the effect of controlling the stream of potential paranoia evoking events in a virtual restaurant world. A 2-by-2 experiment with a non-clinical group (n = 24) was conducted with as two wit...

Abstract. Experiences of bullying in the workplace can increase anxiety, paranoia, and hypervigilance to threat victims. Such factors are also associated with conspiracy beliefs. Two preregistered studies (cross-sectional experimental) tested whether experiences may be linked development Study 1 ( n = 273) demonstrated that were positively beliefs, an effect could explained by paranoia. In 2 20...

The sociology of mental health focuses on the epidemiology, etiology, correlates, and consequences of mental health (i.e., psychiatric disorder and symptoms, psychological distress, and subjective well-being) in an attempt to describe and explain how social structure influences an individual's psychological health. Critical race theory describes and explains iterative ways in which race is soci...
