How Culture and Musical Engagement Shape Musical Reward Sensitivity in Danish Teens: A Validation Study of the Danish Barcelona Musical Reward Questionnaire With 4641 Adolescents.

The ability to convey emotions and induce pleasure is one of the most important aspects of the way that music becomes meaningful to humans. Affective responses to music are specific to both cultural and personal preferences, but little is known about the individual variability in adolescence. The Barcelona Music Reward Questionnaire (BMRQ) is a psychometric measure that identifies five factors associated with musical pleasure: Musical Seeking, Emotional Evocation, Mood Regulation, Social Reward, and Sensory-Motor.

Feasibility, tolerability, and first experience of intracystic treatment with peginterferon alfa-2a in patients with cystic craniopharyngioma.

Background: Children with craniopharyngiomas (CPs) typically suffer from a life-long chronic disease. The younger the child, the more vulnerable the maturing brain is to invasive therapies such as surgery or radiotherapy. Therefore, treatment modalities facilitating avoidance or delay of invasive therapies are beneficial for these patients.

The telovelar approach for fourth ventricular tumors in children: is removal of the posterior arch of C1 necessary?

Purpose: Various surgical nuances of the telovelar approach have been suggested. The necessity of removing the posterior arch of C1 to accomplish optimal tumor exposure is still debated. Therefore, we report on our experience and technical details of the fourth ventricular tumor resection in a modified prone position without systematic removal of the posterior arch of C1.

Abnormalities of the Descending Inhibitory Nociceptive Pathway in Functional Motor Disorders.

Background: Pain is a common disabling non-motor symptom affecting patients with functional motor disorders (FMD).

Objective: We aimed to explore ascending and descending nociceptive pathways with laser evoked potentials (LEPs) in FMD.

Methods: We studied a "bottom-up and top-down" noxious paradigm applying a conditioned pain modulation (CPM) protocol and recorded N2/P2 amplitude in 21 FMD and 20 controls following stimulation of both right arm and leg at baseline (BS) (bottom-up), during heterotopic noxious conditioning stimulation (HNCS) with ice test (top-down) and post-HNCS.

Dual-Catalysed Intermolecular Reductive Coupling of Dienes and Ketones.

We report a mild, catalytic method for the intermolecular reductive coupling of feedstock dienes and styrenes with ketones. Our conditions allow concomitant formation of a cobalt hydride species and single-electron reduction of ketones. Subsequent selective hydrogen-atom transfer from the cobalt hydride generates an allylic radical which can selectively couple with the persistent radical-anion of the ketone.

Reduced Interoception Abilities in Patients with Restless Legs Syndrome.

Background: Restless legs syndrome (RLS) is a complex sensorimotor disorder occurring with a typical circadian fashion. Association with additional features, like alexithymia and nocturnal compulsive behaviors further complicates the framework.

Objectives: To assess interoception in RLS.

Defect of the Endogenous Inhibitory Pain System in Idiopathic Restless Legs Syndrome: A Laser Evoked Potentials Study.

Background: Restless legs syndrome (RLS) is a complex sensorimotor disorder. Symptoms worsen toward evening and at rest and are temporarily relieved by movement. Symptoms are perceived as painful in up to 45% of cases, and nociception system may be involved.

Learning to play a musical instrument in the middle school is associated with superior audiovisual working memory and fluid intelligence: A cross-sectional behavioral study.

Music training, in all its forms, is known to have an impact on behavior both in childhood and even in aging. In the delicate life period of transition from childhood to adulthood, music training might have a special role for behavioral and cognitive maturation. Among the several kinds of music training programs implemented in the educational communities, we focused on instrumental training incorporated in the public middle school curriculum in Italy that includes both individual, group and collective (orchestral) lessons several times a week.

REM sleep behavior disorder: Mimics and variants.

Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia with dream-enactment behaviors occurring during REM sleep and associated with the lack of the physiological REM sleep muscle atonia. It can be isolated and secondary to other neurological or medical conditions. Isolated RBD heralds in most cases a neurodegenerative condition due to an underlying synucleinopathy and consequently its recognition is crucial for prognostic implications.

[Viral zoonoses].

In different areas of the World, whether in industrialized or developing countries, zoonoses represent an emerging Public Health concern either as known agents appear in areas or species in which they had not been reported or as new pathogens parasite Human as consequence of successful host switching. Epidemiological data outlined that vectorborne viral zoonoses are of particular relevance. This paper review the changes in epidemiology of bat rabies and arbovirus encephalitis.

Sentinel node role in breast cancer surgery.

Radical surgery of breast cancer includes lymphadenectomy of axilla as well as the dissection of the neoplastic tissue. However recently many works have raised doubts on the opportunity of performing routinary axillary dissection, which elevates morbidity risk, in absence of axillary metastases. However, unfortunately, information on axillary lymph node pathology, is not available with any other technique excluding complete dissection and istopathological examination.

Differential pulse polarographic determination of the herbicides atrazine, prometrine and simazine.

A differential pulse polarographic method, using the dropping mercury electrode for the determination of the herbicides atrazine, prometrine and simazine is described. The optimum pH is 2. The limit of detection is 8 x 10(-8)M, corresponding to about 15 mu/l.

Determination of nickel in the serum of occupationally exposed workers, by means of flame atomic-absorption spectroscopy.

A flame atomic-absorption spectroscopy method for determination of nickel in the serum of occupationally exposed subjects has been developed. Trichloroacetic add is utilized for precipitating proteins and freeing bound nickel; sodium diethyldithiocarbamate is used as complexing agent and isopropyl acetate as the solvent for extraction. The method is characterized by good accuracy, precision and sensitivity, over a concentration range up to about 20 ng/ml.

Pulse polarography of nitrosated GPC fractions of humic acids.

A pulse polarographic method for the analysis of humic acids fractionated by gel permeation chromatography is described. It is concluded that the pulse polarography of the nitroso-derivatives, already reported as an analytical method for the determination of humic acids, really gives responses due to the presence of iron in the samples. Atomic-absorption measurements confirm this conclusion quite unambiguously.
