Cav2.2 N-type voltage-dependent Ca2+ channel (VDCC) expressed in neurons is known to be essential for neurotransmitter release. We have shown previously that this channel is also expressed in nonexcitable microglia and plays pivotal roles in microglial functions. Here, we have examined the effects of microglia-specific knockdown (KD) of Cav2.2 channel in a mouse model of Parkinson's disease (PD). We found that the KD of Cav2.2 channel reduces the accumulation of microglia in the substantia nigra and ameliorates the behavioral deficits in PD model mice. These results are in marked contrast with those found in microglia-specific KD of Cav1.2 L-type channel, where exacerbated symptoms are observed. Our results suggest that blockade of microglial Cav2.2 N-type VDCC is beneficial for the treatment of PD.Purpose High-dose-rate (HDR) brachytherapy is an established technique to be used as monotherapy option or focal boost in conjunction with external beam radiation therapy (EBRT) for treating prostate cancer. Radiation source path reconstruction is a critical procedure in HDR treatment planning. Manually identifying the source path is labor intensive and time inefficient. In recent years, magnetic resonance imaging (MRI) has become a valuable imaging modality for image-guided HDR prostate brachytherapy due to its superb soft-tissue contrast for target delineation and normal tissue contouring. The purpose of this study is to investigate a deep-learning-based method to automatically reconstruct multiple catheters in MRI for prostate cancer HDR brachytherapy treatment planning. Methods Attention gated U-Net incorporated with total variation (TV) regularization model was developed for multi-catheter segmentation in MRI. The attention gates were used to improve the accuracy of identifying small catheter points, whiror of less then 2.0 mm, while 63% were within 1.0 mm. Conclusions In this study, we proposed a novel multi-catheter detection method to precisely localize the tips and shafts of catheters in three-dimensional MRI images of HDR prostate brachytherapy. It paves the way for elevating the quality and outcome of MRI-guided HDR prostate brachytherapy.Inflammation represents an important factor leading to metabolic imbalance within the intervertebral disc (IVD), conducive to degenerative changes. Therefore, a thorough knowledge of the IVD and endplate (EP) cell behaviour in such pathological environments is essential when designing regenerative therapeutic strategies. The present study aimed at assessing the molecular response of the IVD constitutive nucleus pulposus (NPCs)-, annulus fibrosus (AFCs)- and endplate (EPCs)-derived cells to interleukin (IL)-1β treatment, through large-scale, high-throughput microarray and protein analysis, identifying the differentially expressed genes and released proteins. Overall, the inflammatory stimulus downregulated stemness genes while upregulating pro-inflammatory, pro-angiogenic and catabolic genes, including matrix metalloproteases, which were not balanced by a concomitant upregulation of their inhibitors. Upregulation of anti-inflammatory and anabolic tumour necrosis factor inducible gene 6 protein (TNFAIP6), of IL-1 receptor antagonist (IL-1Ra) (at gene and protein levels) and of trophic insulin-like growth factor 1 (IGF1) was also observed in all cell types; IGF1 particularly in AFCs. An overall inhibitory effect of tumour necrosis factor alpha (TNFα) signal was observed in all cell types; however, EPCs showed the strongest anti-inflammatory behaviour. AFCs and EPCs shared the ability to limit the activation of the signalling mediated by specific chemokines. AFCs showed a slightly senescent attitude, with a downregulation of genes related to DNA repair or pro-mitosis. Results allowed for the identification of specific molecular targets in IVD and EP cells that respond to an inflammatory environment. Such targets can be either silenced (when pathological targets) or stimulated to counteract the inflammation.Reaction on 'Does ambulantization lead to more imprisonment of psychiatric patients?'Following an audit, the flexible assertive community treatment-teams (FACT-teams), in Winterswijk, the Netherlands, set out to discover a more recovery-oriented approach to treatment and monitoring. Their findings support researching four recovery phases described previously. CONCLUSION Monitoring and interviewing based on the four recovery phases subjectively leads to more in-depth and more recovery-oriented evaluations of treatment. More empirical research into this method is necessary.The name Maurits Escher is inextricably linked with the notion of 'optical illusion', a type of illusion evoked by his 'impossible figures'. Despite the sober style in which he realised these figures, they go on to mesmerise generations of art lovers. It is unclear what causes this, and whether other factors than aesthetic ones are involved. CONCLUSION Fundamental research may benefit from Escher's 'impossible figures' to fathom the rules of our visual grammar. The optical illusions they evoke moreover constitute an ongoing source of inspiration for other artists, architects, and film makers.The constructivist position is often used for psychiatric diseases, in contrast with the general medical view. buy Cyclosporine A In the medical view a biological substrate is decisive for a classification as 'disease', which is not the case in the constructivist position. CONCLUSION Hacking's philosophy makes it possible to move beyond the opposition between the medical and the constructivist account of psychiatric diseases by combining both accounts.Quetiapine is a frequently prescribed antipsychotic and therefore often used in overdose. Delirium (with anticholinergic delirium as a specific condition) is described as a serious complication of quetiapine intoxication. CONCLUSION Delirium due to quetiapine intoxication is described repeatedly. Presumably there is an underreporting of this condition and associated symptoms. Better knowledge could lead to better detection and treatment.The primary goal of disciplinary law is to enhance medical care by learning from mistakes and taking preventive measures. Disciplinary law affects the individual big (Healthcare Professionals Act) registered professionals. Furthermore, it is about quality control of professional practice. CONCLUSION Awareness through the analysis of disciplinary complaints at the psychiatrist's group level can offer opportunities for preventive measures and improve the quality of care.
