Background: Substance abuse and consequently the use of methadone in Iran are reported at high levels. Drugs alter sexual function by affecting the organs of the body. The aim of this study was to evaluate sexual functioning and serum testosterone levels in opiate addicts, individuals receiving methadone maintenance treatment (MMT), and healthy men living in the city of Rafsanjan, Iran, in 2016...

Abstract Soil moisture is among the most important factors regulating soil biodiversity and functioning. Models forecast changes in precipitation regime many areas of planet, but how these will influence functioning, biotic drivers modulate such effects, far from being understood. We evaluated responses C N fluxes, microbial properties to different water regimes soils main three ecotypes world'...

International extension networks provide vital services to stakeholders using a variety of organizational structures. To continue offering desired by stakeholders, it is important that both public and private develop effective functioning capacities. Despite this need, an instrument empirically examine the perceived capacities international network institutional was unavailable in literature. T...

The executive functions (including response inhibition, memory updating, and task switching) appear to form the core of higher-order cognitive processes in humans. Relatively little research has been devoted to the role of the executive functions in emotional and motivational processes. The current article surveys evidence on the contributions of individual differences in executive functioning ...

There are many ways to include stochastic effects in models of sex allocation evolution. These include variability in the number of mating partners and fecundity in a rich literature that goes back 20 years. The effects of variance in the fecundity and number of mating partners have typically been considered separately from the stochastic effects of mortality. However, I show that these process...

BACKGROUND The effectiveness of a psychosocial skills training (PSST) approach applied to chronic out-patients with schizophrenia was examined. We hypothesized that the PSST programme, which included treatment as usual (TAU), PSST and family therapy (FT), would reduce positive and negative symptoms, prevent relapse and rehospitalization, and improve psychosocial functioning (PSF), global functi...

Quantifying diversity with phylogeny-informed metrics helps understand the effects of diversity on ecosystem functioning (EF). The sign of these effects remains controversial because phylogenetic diversity and taxonomic identity may interactively influence EF. Positive relationships, traditionally attributed to complementarity effects, seem unimportant in natural soil bacterial communities. Neg...

The evolution of dioecy from a monomorphic hermaphroditic condition requires two mutations, one producing females and one producing males. Conversely, a single mutation sterilizing one sexual function in one morph of distylous species would result in functional dioecy because such a mutation also affects the complementary function in the other morph. In this study, we tested these ideas with Er...

To investigate the role of inhibitory control in preschoolers' ability to switch sets, 3 conditions of the Dimensional Change Card Sort task ( Zelazo, Reznick, & Pinon, 1995) were tested. In Condition B (novel response options, standard stimuli) action inhibition was reduced, but the need for attentional inhibition was maintained. In Condition C (novel stimuli, standard response options) demand...
