Summary: The study aimed to alleviate levodopa-induced dyskinesia in Parkinson's disease by reducing Fyn expression. Preadministration of miRNA-Fyn was effective in reducing LID, while post-L-DOPA delivery of miRNA-Fyn was less effective in reverting established dyskinesia. The findings suggest that early blocking of Fyn activity may be a more efficient therapeutic approach.

Summary: This study compared the validity of motor state quantification between the Parkinson's disease (PD) home diary and direct clinical observation in fluctuating PD patients. The results showed that the home diary inadequately reflects actual motor states compared to direct clinical observation.

Summary: The Motor fluctuations Monitor for Parkinson's Disease (MM4PD) is an ambulatory monitoring system that tracks fluctuations in resting tremor and dyskinesia, correlated to clinical evaluations and expert ratings. It has potential to support patient-clinician communication and medication adjustments.

Summary: Mitophagy dysfunction caused by gene mutations is associated with the development of Parkinson's Disease (PD). However, the association between the variants of mitophagy-related genes and the treatment with levodopa (LD) in PD patients has not been well explored. This study investigated the association of 14 variants of the PRKN gene with LD treatment in PD patients. The results suggest that while age at onset of symptoms, duration of PD, and LD treatment and dosage can influence the occurrence of dyskinesia, the investigated PRKN variants did not show a significant association.

Summary: A large proportion of drugs for neurological disorders are derived from naturally occurring compounds, especially plant alkaloids. The treatment of Parkinson's disease has strong botanical origins, with plant-derived substances playing a significant role. The interaction between plant compounds and animal dopaminergic systems has deep evolutionary roots.

Summary: Depotentiation mechanisms of heterosynaptic plasticity are preserved in Parkinson's disease patients, indicating the potential for reversing abnormal brain plasticity. Cerebellar stimulation enhances heterosynaptic plasticity in both dyskinetic and non-dyskinetic PD patients, suggesting a possible therapeutic target for improving motor symptoms.

Summary: The study reviews the dopamine replacement therapy with L-DOPA commonly used in the treatment of Parkinson's disease, focusing on the role of the striatal direct and indirect pathways in the pathological motor consequences. It discusses how alterations in the efferent circuitry of the striatum and changes in synaptic plasticity and firing patterns can contribute to dyskinesia development. Recent findings suggest that an imbalance in the activity between both striatal pathways is sufficient to cause dyskinesia in both rodent and primate models of Parkinson's disease.

Summary: Cerebellar transcranial alternating current stimulation (tACS) can specifically enhance cerebellar motor cortex (M1) inhibition, particularly during the application of 5Hz tACS. The effects of 5Hz tACS appear to be site-specific and do not induce long-lasting effects.

Summary: This study investigated the relationship between serum uric acid (UA) levels and levodopa-induced dyskinesia (LID) in Parkinson's disease (PD) patients, as well as the associations between UA levels and clinical features of PD. The results showed that the dyskinesia group had lower serum UA levels compared to the no dyskinesia group, which was also observed in both men and women. Multivariate analysis demonstrated that lower UA levels were significantly associated with the presence of dyskinesia. Additional analysis revealed that serum UA levels were inversely correlated with depressive symptoms, disease duration, MDS-UPDRS IV, and time spent with dyskinesia, while positively correlated with age at onset of PD symptoms.

Summary: Prostate cancer is one of the most common tumors in males and a major cause of death in Western countries. When standard treatment fails, novel therapies have dramatically improved the prognosis of advanced prostate cancer. However, there is a need for imaging biomarkers to assess treatment response and personalize therapeutic approaches.

Summary: Immersive virtual reality can lead to a strong feeling of embodiment over artificial body parts, but the neural mechanisms behind this phenomenon are not yet fully understood. By tracking real-time brain dynamics, researchers found that observing virtual body parts is associated with a rapid decrease in cortical activity in the hand region of the primary motor cortex, as well as rapid changes in activity within a fronto-parietal circuit. These findings suggest that changes in bodily representations are supported by dynamic interactions within a highly plastic network.

Summary: This pilot study evaluated the capability of a digital autoradiography system to perform biodistribution evaluation of [F-18] choline in a xenograft mouse model of prostate cancer. The results showed that the system could accurately assess the biodistribution of the radiopharmaceutical and demonstrate tumor-specific uptake. Immunohistochemical analysis also confirmed a strong correlation between [F-18] choline uptake and tumor proliferation index.

Summary: This study found that stimulating the left and right DLPFC with 40 Hz tACS can increase blood oxygenation level-dependent activity in the targeted DLPFCs and surrounding areas according to biophysical modeling. However, off-target effects on visual cortices, SMA, left subgenual cingulate, and right superior temporal gyrus were also observed.

Summary: This study reviewed the application of radiolabeled-FAPI in patients with pancreatic cancer, discussing its advantages, disadvantages, and future prospects, especially in the field of theragnostic. A literature search was performed in PubMed, EBSCO, and EMBASE databases, and 21 studies were selected for comprehensive analysis. The results showed that FAPI could better detect pancreatic malignant lesions, but further prospective studies are needed to validate its effectiveness.

Summary: In the past decade, two new radionuclide-based therapies, (223)Radichloride and radioligand therapy (RLT) targeting prostate-specific membrane antigen (PSMA), have been approved for the management of castrate-resistant prostate cancer (PCa). This article illustrates the basic principles of PCa molecular imaging, with a focus on the combined use of diagnosis and therapy for response prediction and assessment. Radiomics, an emerging discipline based on quantitative features extracted from medical images, is also discussed for its potential in this field.

Summary: Using the novel data-driven method DEBM, this study determined the sequence of several common biomarker changes in Parkinson's disease (PD). The left putamen was found to be the earliest biomarker to become abnormal, followed by the right putamen, CSF alpha-synuclein, right caudate, left caudate, and serum NfL. The estimated disease stages showed significant differences between PD and healthy controls, and achieved a high accuracy for distinguishing PD from HC.

Summary: This study aimed to investigate the incidence and risk factors for institutionalisation in Parkinson's disease (PD) and atypical parkinsonism (AP). The study found that institutionalisation was more frequent in AP compared to PD and controls. Age, poorer cognition, and more-severe parkinsonian impairment were independent predictors of institutionalisation.
