Degeneration of dopamine (DA) neurons in the substantia nigra pars compacta (SNc) causes the motor symptoms (e.g. tremor, muscle rigidity, bradykinesia, postural instability) of Parkinson's disease (PD). It is generally agreed that replacing these neurons will provide better motor symptom relief and fewer side effects than current pharmacotherapies. One potential approach to this is up-regulating endogenous DA neurogenesis in SNc. In the present study, we conducted bioinformatics analyses to identify signalling pathways that control expression of Pax6 and Msx1 genes, which have been identified as potentially important neurogenic regulators in the adult midbrain...

Diffuse low-grade gliomas (DLGG) prognosis is variable, depending on several factors, including the isocitrate dehydrogenase (IDH) mutation and the 1p19q codeletion. A few studies suggested associations between these parameters and tumor radiological characteristics including topography. Our aim was analyzing the correlations between the IDH and 1p19q statuses and the tumor intracerebral distribution (at the lobar and voxel levels), volume, and borders. We conducted a retrospective, monocentric study on a consecutive series of 198 DLGG patients...

The common knowledge of a uniqueness of REM sleep as a privileged scenario of dreaming still persists, although consolidated empirical evidence shows that the assumption that dreaming is just an epiphenomenon of REM sleep is no longer tenable. However, the brain mechanisms underlying dream generation and its encoding in memory during NREM sleep are still mostly unknown. In fact, only few studies have investigated on the mechanisms of dream phenomenology related to NREM sleep. For this reason, our study is specifically aimed to elucidate the electrophysiological (EEG) correlates of dream recall (DR) upon NREM sleep awakenings...

PURPOSES: Researchers studying trauma have found that physicians are able to perform a focused assessment with sonography for trauma (FAST) with minimal training and achieve ideal accuracy. However, there are currently no consensus or standard guidelines regarding the performance of this assessment. The aim of our study was to clarify the value of FAST performed by well-qualified senior general surgery residents in cases of suspected blunt abdominal trauma, which presents an important diagnostic problem in emergency departments...

Mobile phone use while riding a motorcycle poses a key safety risk, particularly among younger people who have been found to be more susceptible to distracted driving. While previous research has examined the influence of social networks on mobile phone use while driving a car, no research has explored this association in the context of motorcycle use. Using a survey of university students in Vietnam, this research explores the association between social networks and mobile phone use among motorcyclists and the links this has to reported crashes/falls...

OBJECTIVE: Gingival overgrowth is a side effect associated with some distinct classes of drugs, such as anticonvulsants, immunosuppressants, and calcium channel blockers. One of the main drugs associated with gingival overgrowth is the antiepileptic phenytoin, which affects gingival tissues by altering extracellular matrix metabolism. It has been shown that mutation of human SOS1 gene is responsible for a rare hereditary gingival fibromatosis type 1, a benign gingival overgrowth. The aim of the present study is to evaluate the possible contribution of SOS1 mutation to gingival overgrowth-related phenotype...
