Parkinson's disease (PD) is a serious neurodegenerative disorder that lacks effective therapeutic methods. In this research, expressions of PPARα, RXRα, and miR-21 were evaluated in PD patients and normal controls. To investigate the effects of miR-21, docosahexaenoic acid (DHA) and aspirin (ASA) on PD, as well as the relationships between them, SH-Y5Y cells were treated with DHA, ASA, or both for 24 h. The assay showed that levels of miR-21 were increased and levels of PPARα were decreased in PD patients compared with normal controls...

Giant prolactinomas, rare in children, can have devastating endocrine, neurological and visual sequelae. Dopamine agonists (DA) are effective first-line therapy with few side-effects at doses usually used for prolactinoma treatment(1) , but higher-dose therapy for Parkinson's disease has well-recognized associations with impulse control disorders (ICD) including pathological gambling, impulsive eating, compulsive shopping and hypersexuality. Such associations are not well recognized with prolactinomas; to our knowledge this is the first reported case of hypersexuality in an adolescent receiving cabergoline for a giant prolactinoma...

Neurodegeneration and neuroinflammation are key features in a range of chronic central nervous system (CNS) diseases such as Alzheimer's and Parkinson's disease, as well as acute conditions like stroke and traumatic brain injury, for which there remains significant unmet clinical need. It is now well recognized that current cell culture methodologies are limited in their ability to recapitulate the cellular environment that is present in vivo, and there is a growing body of evidence to show that three-dimensional (3D) culture systems represent a more physiologically accurate model than traditional two-dimensional (2D) cultures...

A distinctive feature of cancer cells is their elevated levels of reactive oxygen species (ROS), a trait that can cause cancer cells to be more sensitive to ROS-inducing agents than normal cells. ROS takes several forms, each with different reactivity and downstream consequence. Here we show that simultaneous generation of superoxide and hydrogen peroxide within cancer cells results in significant synergy, causing potent and selective cancer cell death. In these experiments superoxide is generated using the NAD(P)H quinone oxidoreductase 1 (NQO1) substrate deoxynyboquinone (DNQ), and hydrogen peroxide is generated using the lactate dehydrogenase A (LDH-A) inhibitor NHI-Glc-2...

BACKGROUND: Mild parkinsonian signs (MPS) are frequent in the elderly population and associated with the presence of risk markers for Parkinson's disease (PD). Both MPS and non-motor signs may be present in prodromal PD and may significantly impair quality of life (QoL). OBJECTIVE: To disentangle the contribution of motor impairment and extra-motor manifestations to QoL in subjects with MPS (n=63), manifest PD (n=69), disorders with motor symptoms due to non-neurodegenerative diseases (n=213) and healthy controls (n=258)...

The duration of action of oral levodopa becomes shorter as Parkinson's disease (PD) progresses. Patients with advanced PD may develop potentially disabling motor fluctuations and abnormal involuntary movement (dyskinesia), which cannot be managed with optimized oral or transdermal PD medications. The progressively worsening symptoms can have a substantial impact on the patient quality of life (QoL). Levodopa-carbidopa intestinal gel (LCIG) is delivered continuously via a percutaneous endoscopic gastrostomy with a jejunal extension (PEG-J)...

Thrombin, an essential component in the coagulation cascade, participates in the pathogenesis of brain diseases, such as ischemic stroke, intracerebral hemorrhage, Alzheimer's disease and Parkinson's disease through blood-brain barrier (BBB) dysfunction. It is thought that the thrombin-matrix metalloproteinase (MMP)-9 axis is an important process in the pathogenesis of neurovascular disease, such as BBB dysfunction. We recently reported that brain pericytes are the most MMP-9-releasing cells in response to thrombin stimulation among the BBB-constituting cells...

In Parkinson's disease (PD), dopamine depletion causes major changes in the brain, resulting in the typical cardinal motor features of the disease. PD neuropathology has been restricted to postmortem examinations, which are limited to only a single time of PD progression. Models of PD in which dopamine tone in the brain is chemically or physically disrupted are valuable tools in understanding the mechanisms of the disease. The basal ganglia have been well studied in the context of PD, and circuit changes in response to dopamine loss have been linked to the motor dysfunctions in PD...

Microgliosis and inflammation are major wrongdoers in cypermethrin-induced Parkinsonism along with oxidative stress, mitochondrial dysfunction and α-synuclein aggregation. Dopamine depletion could alter dendritic morphology, length and spine number in the striatum. Present study investigated the effect of ibuprofen on the dendritic morphology, length and spine density in cypermethrin PD model. Male pups were treated intraperitoneally with cypermethrin during postnatal days followed by adulthood to induce Parkinsonism using standard procedure along with controls...

Amyloidogenic peptide oligomers are responsible for a variety of neurodegenerative disorders such as Alzheimer's and Parkinson's disease. Due to their dynamic, polydisperse, and polymorphic nature, these oligomers are very challenging to characterize using traditional condensed-phase methods. In the last decade, ion mobility-mass spectrometry (IM-MS) and related gas-phase techniques have emerged as a powerful alternative to disentangle the structure and assembly characteristics of amyloid forming systems. This review highlights recent advances in which IM-MS was used to characterize amyloid oligomers and their underlying assembly pathway...

Autoimmune disorders are distinct with over production and accumulation of free radicals due to its undisclosed genesis. The cause of numerous disorders as cancer, arthritis, psoriasis, diabetes, alzheimer's, cardiovascular disease, Parkinson's, respiratory distress syndrome, colitis, crohn's, pulmonary fibrosis, obesity and ageing have been associated with immune dysfunction and oxidative stress. In an oxidative stress, reactive oxygen species generally provoke the series of oxidation at cellular level. The buildup of free radicals in turn triggers various inflammatory cells causing release of various inflammatory interleukins, cytokines, chemokines, and tumor necrosis factors which mediate signal transduction and transcription pathways as nuclear factor- kappa B (NF-κB), signal transducer and activator of transcription 3 (STAT3), hypoxia-inducible factor-1 (HIF-1α) and nuclear factor-erythroid 2-related factor (Nrf2)...

l-DOPA remains the benchmark treatment for Parkinson's disease (PD) motor symptoms, but chronic use leads to l-DOPA-induced dyskinesia (LID). The serotonin (5-HT) system has been established as a key modulator of LID and 5-HT1A receptors (5-HT1AR) stimulation has been shown to convey anti-dyskinetic effects. However, 5-HT1AR agonists often compromise clinical efficacy or display intrinsic side effects and their site(s) of actions remain debatable. Recently, highly selective G-protein biased 5-HT1AR agonists, F13714 and F15599, were shown to potently target 5-HT1A auto- or hetero-receptors, respectively...

Motor imagery involves cortical networks similar to those activated by real movements, but the extent to which the basal ganglia are recruited is not yet clear. Gamma and beta oscillations in the subthalamic nucleus (STN) vary with the effort of sustained muscle activity. We recorded local field potentials in Parkinson's disease patients and investigated if similar changes can be observed during imagined gripping at three different 'forces'. We found that beta activity decreased significantly only for imagined grips at the two stronger force levels...
