Morgellons Disease is a condition involving painful skin lesions, fibrous growths protruding from the skin, and subcutaneous stinging and burning sensations, along with symptoms of anxiety, depression, fatigue, and memory and attention deficits. The etiological and physiological bases of these symptoms are unclear, making the diagnosis controversial and challenging to treat. There are currently...

OBJECTIVE Functional imaging studies have found reduced frontal activity, mainly in dorso/ventro-lateral regions and reduced task-related de-activation of the default mode network in childhood ADHD. Adult studies are fewer and inconclusive. We aimed to investigate the potential neural bases of executive function in ADHD adults, examining brain activity during N-back task performance, and to exp...

BACKGROUND Enuresis (9% at age 9.5) negatively affects children's psychosocial status. Clinically-diagnosed enuresis (2% at the age) is associated with hyperactivity-inattention, and common neural bases have been postulated to underlie this association. It is, however, unclear whether this association is applicable to enuresis overall among the general population of early adolescents when consi...

INTRODUCTION Methylphenidate is the first-line pharmacological treatment of attention-deficit/hyperactivity disorder (ADHD). Although methylphenidate has a well-established evidence base for treating ADHD, its long-term benefits are unclear. Areas covered: Physical adverse effects, psychiatric adverse events and brain development Expert opinion: Some physical adverse events have been described ...

Clival chordomas are frequently midline structures. Due to their critical location, invasive nature and aggressive recurrences, skull base chordomas are difficult to manage surgically. We present a case operated on with the pedicled transnasal and transfacial approach. The case presented with neurological deficits as cranial nerve palsy and findings of brainstem compression. The lesion was remo...

Attention deficit/hyperactivity disorder (ADHD) is the behavioural disorder most commonly diagnosed in childhood. In addition to the main symptoms of inattention, impulsiveness and hyperactivity, neurological soft signs (NSS) are often associated with ADHD. NSS are discrete motor and sensory disorders that cannot be linked to specific cerebral lesions. We review all the scientific contributions...

Several mechanisms contributed to the development of credit rationing of enterprises. First, the abandonment of implicit guarantees on loans extended to enterprises by the Central Bank of Russia prompted commercial banks to shift credit to other groups of borrowers. Second, when the Federal Government moved to finance its budgetary deficit through open-market operations, it crowded out commerci...

The “resource-based view of the firm” has become an important conceptual framework in strategic management but has been widely criticized for lack of an empirical base. To address this deficit, we utilize a new method for identifying inter-firm differences in efficiency within the context of stochastic frontier production functions. Using data on Japanese and U.S. automobile manufacturers, we d...

The contribution of the thalamus to the functioning of prospective memory (PM) is currently unknown. Here we report an experimental investigation of the performance of two patients with bilateral infarcts in the anterior-mesial regions of the thalami on an event-based PM paradigm. One patient, G.P., had a pervasive declarative memory impairment but no significant executive deficit. The other pa...

Energy and water exchange between the surface atmosphere are important drivers to Earth’s climate from local global scale. In this study, energy dynamic biophysical mechanisms that control partitioning over a natural grassland pasture Brazilian Pampa biome investigated using two micrometeorological sites located 300 km apart, in Southern Brazil. The latent heat flux, LE, was main component of b...
