The prefrontal cortex (PFC) is involved in behavioural control and cognitive processes that are altered in schizophrenia. The brainstem monoaminergic systems control PFC function, yet the cells/networks involved are not fully known. Serotonin (5-HT) and norepinephrine (NE) increase PFC neuronal activity through the activation of α1-adrenergic receptors (α1ARs) and 5-HT2A ...

OBJECTIVES: Regarding children's and adolescents' development of physical fitness (PF), information about whether there are different performance classes in PF would potentially be helpful. If such classes also differ in related health parameters, this might indicate 'at-risk' groups requiring different support measures. METHODS: Factor mixture modeling was used to investigate ...

Bacterial cultures were enriched from sediments in Germany and Vietnam reductively dechlorinating hexachlorobenzene and the highly persistent 1,3,5-trichlorobenzene to monochlorobenzene. The main products of the reductive dechlorination of hexachlorobenzene were monochlorobenzene and dichlorobenzenes (1,2-; 1,3- and 1,4-dichlorobenzene) while no trichlorobenzenes accumulated. For the reductive dechlorination of 1,3,5-trichlorobenzene with the mixed ...

Parkinson's disease (PD) is a chronic progressive neurodegenerative disorder with a considerable socioeconomic burden. The pathomechanism of PD clearly involves the synergistic interaction of dopaminergic and glutamatergic dysfunctioning, including maladaptive corticostriatal synaptoplasticity. Most of the available treatment options have the aim of restoration of the physiological dopaminergic activity. Currently, the ...

When a planetary tidal disk--like Saturn's rings--spreads beyond the Roche radius (inside which planetary tides prevent aggregation), satellites form and migrate away. Here, we show that most regular satellites in the solar system probably formed in this way. According to our analytical model, when the spreading is slow, a retinue ...
