Influence of painful physical symptoms in the treatment of Japanese patients with melancholic major depressive disorder: A prospective cohort study.

The aim of this study was to clarify how painful physical symptoms affect treatment outcomes in patients with melancholic major depressive disorder. The subjects comprised 100 consecutive Japanese outpatients with melancholic major depressive disorder who visited our clinic from October 2011 to October 2014. All subjects were interviewed for Diagnostic and Statistical Manual of Mental Disorders Axis 2, 3, and 4 and family history of major depressive disorder, and then grouped according to the presence of painful physical symptoms.

Effect of augmentation with olanzapine in outpatients with depression in partial remission with melancholic features: consecutive case series.

The aim of the present 12-week, open-label study was to investigate the effect of olanzapine augmentation in outpatients with depression with melancholic features who demonstrated partial response to standard antidepressants but who were reluctant to change antidepressants. The subjects consisted of 22 outpatients meeting the DSM-IV-TR criteria for major depression. Olanzapine was initially added at 2.

The acceptance rate of young wasps by alien colonies depends on colony developmental stages in the swarm-founding wasp, Polybia paulista von ihering (Hymenoptera: Vespidae).

In social insects, newly emerged individuals learn the colony-specific chemical label from their natal comb shortly after their emergence. These labels help to identify each individual's colony of origin and are used as a recognition template against which individuals can discriminate nestmates from non-nestmates. Our previous studies with Polybia paulista von Ihering support this general pattern, and the acceptance rate of young female and male wasps decreased as a function of their age.

Nest thermoregulation in Polybia scutellaris (White) (Hymenoptera: Vespidae).

Polybia scutellaris (White) builds large nests characterized by numerous spiny projections on the surface. In order to determine whether or not the nest temperature is maintained because of homeothermic conditions of the nest individuals or otherwise, we investigated the thermal conditions within the nests built by P. scutellaris.

A long slit-like entrance promotes ventilation in the mud nesting social wasp, Polybia spinifex: visualization of nest microclimates using computational fluid dynamics.

Polybia spinifex Richards (Hymenoptera: Vespidae) constructs mud nests characterized by a long slit-like entrance. The ventilation and thermal characteristics of the P. spinifex nest were investigated to determine whether the nest microclimate is automatically maintained due to the size of the entrance.

Promotion of thermoregulatory insulation in nests of neotropical wasps by building extra-combs with empty cells.

We examined the hypotheses that the empty combs of Polybia occidentalis Olivier (Hymenoptera: Vespidae) nest insulate the inside of the nest. To examine this hypotheses, two kinds of temperature measurements were carried out: 1) with the outer comb of the nest intact (Control) and 2) removed (Treatment), using a large and a small nest. In the large nest, the daily nest temperatures (outer part, Tn1; inner part, Tn2) in Control were lower by 0.

Passive body heating ameliorates sleep disturbances in patients with vascular dementia without circadian phase-shifting.

Objective: This study investigated the sleep-promoting, thermoregulatory, and circadian phase-shifting actions of passive body heating (PBH) in elderly insomniac patients (IPs) with mild-to-moderate vascular dementia.

Methods: Thirteen elderly IPs with vascular dementia (mean age 76.9 years; male/female ratio 2/11) were subjected to a PBH trial session.
