Efficient cavity-assisted storage of photonic qubits in a solid-state quantum memory.

We report on the high-efficiency storage and retrieval of weak coherent optical pulses and photonic qubits in a cavity-enhanced solid-state quantum memory. By using an atomic frequency comb (AFC) memory in a Pr:YSiO  crystal embedded in an impedance-matched cavity, we stored weak coherent pulses at the single photon level with up to 62% efficiency for a pre-determined storage time of 2 µs. We also confirmed that the impedance-matched cavity enhances the efficiency for longer storage times up to 70 µs.

Modulation of subthalamic beta oscillations by movement, dopamine, and deep brain stimulation in Parkinson's disease.

Subthalamic beta band activity (13-35 Hz) is known as a real-time correlate of motor symptom severity in Parkinson's disease (PD) and is currently explored as a feedback signal for closed-loop deep brain stimulation (DBS). Here, we investigate the interaction of movement, dopaminergic medication, and deep brain stimulation on subthalamic beta activity in PD patients implanted with sensing-enabled, implantable pulse generators. We recorded subthalamic activity from seven PD patients at rest and during repetitive movements in four conditions: after withdrawal of dopaminergic medication and DBS, with medication only, with DBS only, and with simultaneous medication and DBS.

Cohort profile: BioMD-Y (biopsychosocial factors of major depression in youth) - a biobank study on the molecular genetics and environmental factors of depression in children and adolescents in Munich.

Purpose: BioMD-Y is a comprehensive biobank study of children and adolescents with major depression (MD) and their healthy peers in Germany, collecting a host of both biological and psychosocial information from the participants and their parents with the aim of exploring genetic and environmental risk and protective factors for MD in children and adolescents.

Participants: Children and adolescents aged 8-18 years are recruited to either the clinical case group (MD, diagnosis of MD disorder) or the typically developing control group (absence of any psychiatric condition).

Findings To Date: To date, four publications on both genetic and environmental risk and resilience factors (including , glucocorticoid receptor activation, polygenic risk scores, psychosocial and sociodemographic risk and resilience factors) have been published based on the BioMD-Y sample.

Anti-PD-1 therapy triggers Tfh cell-dependent IL-4 release to boost CD8 T cell responses in tumor-draining lymph nodes.

Anti-PD-1 therapy targets intratumoral CD8+ T cells to promote clinical responses in cancer patients. Recent evidence suggests an additional activity in the periphery, but the underlying mechanism is unclear. Here, we show that anti-PD-1 mAb enhances CD8+ T cell responses in tumor-draining lymph nodes by stimulating cytokine production in follicular helper T cells (Tfh).

Single threshold adaptive deep brain stimulation in Parkinson's disease depends on parameter selection, movement state and controllability of subthalamic beta activity.

Background: Deep brain stimulation (DBS) is an invasive treatment option for patients with Parkinson's disease. Recently, adaptive DBS (aDBS) systems have been developed, which adjust stimulation timing and amplitude in real-time. However, it is unknown how changes in parameters, movement states and the controllability of subthalamic beta activity affect aDBS performance.

Improving naturalistic neuroscience with patient engagement strategies.

Introduction: The clinical implementation of chronic electrophysiology-driven adaptive deep brain stimulation (DBS) algorithms in movement disorders requires reliable representation of motor and non-motor symptoms in electrophysiological biomarkers, throughout normal life (naturalistic). To achieve this, there is the need for high-resolution and -quality chronic objective and subjective symptom monitoring in parallel to biomarker recordings. To realize these recordings, an active participation and engagement of the investigated patients is necessary.

Evaluation of a web-based information platform on youth depression and mental health in parents of adolescents with a history of depression.

Research shows the important role of parents' mental health literacy in detecting depressive symptoms and supporting their children to seek professional help. Improving mental health literacy in parents has recently gained even greater importance due to the negative impact of the COVID-19 pandemic on children and adolescents' mental health. The aim of the present experimental pre-post-follow-up study was to examine knowledge change after the reception of contents from an innovative web-based platform ( www.

Emotion regulation training for adolescents with major depression: Results from a randomized controlled trial.

Difficulties in emotion regulation (ER) are thought to contribute to the development and maintenance of major depression (MD) in adolescents. In healthy adults, a task-based training of ER has previously proven effective to reduce stress, but no such studies are available for MD. It is also unclear whether findings can be generalized onto adolescent populations.

Emotion regulation in adolescents with major depression - Evidence from a combined EEG and eye-tracking study.

Background: Adolescent major depression (MD) is characterized by deficits in emotion regulation (ER). Little is known about the neurophysiological correlates that are associated with these deficits. Moreover, the additional examination of visual attention during ER would allow a more in-depth understanding of ER deficits but has not yet been applied simultaneously.

Primary Hyperparathyroidism overlapping with Multiple Sclerosis: a catastrophic marriage.

Primary hyperparathyroidism (PHPT) often leads to neurological or psychiatric disorders, thus mimicking different diseases. Here we present a 77-years old man visited in the Emergency Department complaining for fatigue, multiple falls, nausea, anorexia, and constipation. Symptoms were rapidly worsening, and on admission he appeared sleepy, responsive to verbal stimulus, disoriented, dehydrated, unable to maintain upright position.

A First Methodological Development and Validation of ReTap: An Open-Source UPDRS Finger Tapping Assessment Tool Based on Accelerometer-Data.

Bradykinesia is a cardinal hallmark of Parkinson's disease (PD). Improvement in bradykinesia is an important signature of effective treatment. Finger tapping is commonly used to index bradykinesia, albeit these approaches largely rely on subjective clinical evaluations.

Evaluation of an information booklet for adolescents on depression: evidence from a randomized controlled study.

Background: Adolescents with depression often show barriers to seek treatment offers due to various reasons, including limited knowledge about the manifestation of the disorder, its treatment options, or fear of stigmatization. Psychoeducational approaches might reduce these barriers by increasing depression literacy. The aim of the present randomized controlled study was to evaluate whether an innovative and age-appropriate evidence-based information booklet about youth depression increases depression-specific knowledge in adolescents with depression and is also appealing to the target group.

Pallidal Beta Activity Is Linked to Stimulation-Induced Slowness in Dystonia.

Background: Pallidal deep brain stimulation (DBS) effectively alleviates symptoms in dystonia patients, but may induce movement slowness as a side-effect. In Parkinson's disease, hypokinetic symptoms have been associated with increased beta oscillations (13-30 Hz). We hypothesize that this pattern is symptom-specific, thus accompanying DBS-induced slowness in dystonia.

Christmas-Related Reduction in Beta Activity in Parkinson's Disease.

Background: Subthalamic nucleus (STN) beta (13 - 35 Hz) activity is a biomarker reflecting motor state in Parkinson's disease (PD). Adaptive deep brain stimulation (DBS) aims to use beta activity for therapeutic adjustments, but many aspects of beta activity in real-life situations are unknown.

Objective: The aim was to investigate Christmas-related influences on beta activity in PD.

Evaluation of a Web-based Information Platform for Youths on Mental Health During the COVID-19 Pandemic.

During the corona pandemic, youths were confronted with substantial challenges and in urgent need of information on how to prevent mental health problems. This experimental pre-post-follow-up study examined the efficacy and reception of an innovative website ( www.corona-und-du.

A noninvasive method to quantify the impairment of spinal motion ability in Parkinson's disease.

Purpose: There is a high demand on spinal surgery in patients with Parkinson's disease (PD) but the results are sobering. Although detailed clinical and radiological diagnostics were carried out with great effort and expense, the biodynamic properties of the spine of PD patients have never been considered. We propose a noninvasive method to quantify the impairment of motion abilities in patients with PD.

[The Double degree in Health and Sciences Curriculum at the Rouen Health UFR: Current situation and perspectives].

The Double degree in Health and Sciences (DCSS) provides an early training in research for future healthcare professionals. The profound transformation of the healthcare system and the advent of new analytical and digital technologies highlight the urgent need to link research to clinical practice. At the international level, especially in the United States, these programs point out the key role of healthcare professionals with both medical and scientific expertise.

Diurnal modulation of subthalamic beta oscillatory power in Parkinson's disease patients during deep brain stimulation.

Beta-band activity in the subthalamic local field potential (LFP) is correlated with Parkinson's disease (PD) symptom severity and is the therapeutic target of deep brain stimulation (DBS). While beta fluctuations in PD patients are well characterized on shorter timescales, it is not known how beta activity evolves around the diurnal cycle, outside a clinical setting. Here, we obtained chronic recordings (34 ± 13 days) of subthalamic beta power in PD patients implanted with the Percept DBS device during high-frequency DBS and analysed their diurnal properties as well as sensitivity to artifacts.

Visual attention during cognitive reappraisal in adolescent major depression: Evidence from two eye-tracking studies.

Adolescent major depression (MD) is associated with impaired emotion regulation. However, results on cognitive reappraisal (CR) are mixed. Investigation of gaze behavior during CR allows a more thorough understanding of intact and deviant CR processes in MD.
