Unveiling the complexity of learning and decision-making

Reinforcement learning (RL) is crucial for learning to adapt to new environments. In RL, the prediction error is an important component that compares the expected and actual rewards. Dopamine plays a critical role in encoding these prediction errors. In my ...

Development of stimuli-responsive chemistry for tumor-targeted immunotherapy

Céline Jasmin Prange

Cancer immunotherapy is the science of boosting the immune response of patients to fight cancer. Recent advances have brought up treatments with huge success in the clinic. Patients with ad-vanced-stage cancers were long-term cured through checkpoint inhib ...

A Multiscale, Systems-Level, Neuropharmacological Model of Cortico-Basal Ganglia System for Arm Reaching Under Normal, Parkinsonian, and Levodopa Medication Conditions

Vignayanandam Ravindernath Muddapu

In order to understand the link between substantia nigra pars compacta (SNc) cell loss and Parkinson's disease (PD) symptoms, we developed a multiscale computational model that can replicate the symptoms at the behavioural level by incorporating the key ce ...

Genetically encoded betaxanthin-based small-molecular fluorescent reporter for mammalian cells

Leo Scheller, Karl Gademann, Simon Sieber

We designed and engineered a dye production cassette encoding a heterologous pathway, including human tyrosine hydroxylase and Amanita muscaria 4,5-DOPA dioxygenase, for the biosynthesis of the betaxanthin family of plant and fungal pigments in mammalian c ...

Tape-Stripping Electrochemical Detection of Melanoma

Hubert Girault, Horst Pick, Andreas Stephan Lesch, Tzu-En Lin, Yingdi Zhu, Sorour Darvishi

A noninvasive electrochemical melanoma detection approach based on using adhesive tapes for collecting and fixing cells from a suspicious skin area and transferring the cells into a scanning electrochemical microscope (SECM) is presented. The adhesive laye ...

Inhaling xenon ameliorates l -dopa-induced dyskinesia in experimental parkinsonism

Grégoire Courtine, Eduardo Martin Moraud, Tomislav Milekovic, Shiqi Sun

Parkinson's disease motor symptoms are treated with levodopa, but long‐term treatment leads to disabling dyskinesia. Altered synaptic transmission and maladaptive plasticity of corticostriatal glutamatergic projections play a critical role in the pathophys ...

Dopamine induces soluble alpha-synuclein oligomers and nigrostriatal degeneration

Elpida Tsika

Parkinson's disease (PD) is defined by the loss of dopaminergic neurons in the substantia nigra and the formation of Lewy body inclusions containing aggregated alpha-synuclein. Efforts to explain dopamine neuron vulnerability are hindered by the lack of do ...

Multiple scanning electrochemical microscopy mapping of tyrosinase in micro-contact printed fruit samples on polyvinylidene fluoride membrane

Hubert Girault, Andreas Stephan Lesch, Liang Qiao, Fernando Cortes Salazar, Tzu-En Lin, Alexandra Bondarenko

Herein, we introduce three orthogonal and compatible methods for detecting tyrosinase, a key factor in fruit browning and skin disorders, with high spatial resolution by means of scanning electrochemical microscopy (SECM). All methods are performed subsequ ...

Lack of additive role of ageing in nigrostriatal neurodegeneration triggered by alpha-synuclein overexpression

Grégoire Courtine, Laetitia Danielle Philippine Baud, Isabel Laura Vollenweider

Introduction: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons as well as the presence of proteinaceous inclusions named Lewy bodies. alpha synuclein (alpha-syn) is a major constituent o ...

Cathodic pretreatment improves the resistance of boron-doped diamond electrodes to dopamine fouling

Martinus Gijs, Raphaël Etienne Jean Trouillon

The resistance of cathodically and anodically treated boron-doped diamond electrodes to dopamine fouling was investigated. It was found, using cyclic voltammetry and electrochemical impedance spectroscopy, that the cathodic preparation offers an increased ...
