Electron shuttles are widespread in the environments and play important role in microbe-mineral interaction. This study investigated the effects of a model electron shuttle (i.e.， anthraquinone-2， 6-disulfonate， AQDS) on Shewanella oneidensis MR-1-mediated Fenton reaction and subsequent degradation of 2， 2′， 4， 4′-tetrabrominated diphenyl ether (BDE-47). Three Fe(III)-containing minerals， namely， ferrihydrite， goethite and nontronite， were used as electron acceptors and Fe(II) sources. With each mineral， additions of 0.01 – 1 mM AQDS in the reactions significantly enhanced Fe(III) reduction by S. oneidensis MR-1 and increased the amounts of Fe(II) produced in anoxic phase. As a result， the amounts of cumulative ·OH formed in oxic phase were increased by 10% – 287%. Regression analysis revealed that ·OH cumulation has significant linear correlation with sorbed Fe(II) but not aqueous and structural Fe(II). This finding may be ascribed to the higher reactivity of sorbed Fe(II) in oxygenation than the latter two types of Fe(II). With more ·OH， the degradation efficiency of BDE-47 was elevated by 31% – 173%. Collectively， AQDS enhances ·OH formation and BDE-47 degradation by promoting production of Fe(II)， particularly sorbed Fe(II) in S. oneidensis MR-1-mediated Fenton reaction with Fe(III)-containing minerals.

The globus pallidus plays a pivotal role in the basal ganglia circuit. Parkinson's disease is characterized by degeneration of dopamine-producing cells in the substantia nigra, which leads to dopamine deficiency in the brain that subsequently manifests as various motor and non-motor symptoms. This review aims to summarize the involvement of the globus pallidus in both motor and non-motor manifestations of Parkinson's disease. The firing activities of parvalbumin neurons in the medial globus pallidus, including both the firing rate and pattern, exhibit strong correlations with the bradykinesia and rigidity associated with Parkinson's disease. Increased beta oscillations, which are highly correlated with bradykinesia and rigidity, are regulated by the lateral globus pallidus. Furthermore,bradykinesia and rigidity are strongly linked to the loss of dopaminergic projections within the cortical-basal ganglia-thalamocortical loop. Resting tremors are attributed to the transmission of pathological signals from the basal ganglia through the motor cortex to the cerebellum-ventral intermediate nucleus circuit. The cortico–striato–pallidal loop is responsible for mediating pallidi-associated sleep disorders. Medication and deep brain stimulation are the primary therapeutic strategies addressing the globus pallidus in Parkinson's disease. Medication is the primary treatment for motor symptoms in the early stages of Parkinson's disease, while deep brain stimulation has been clinically proven to be effective in alleviating symptoms in patients with advanced Parkinson's disease,particularly for the movement disorders caused by levodopa. Deep brain stimulation targeting the globus pallidus internus can improve motor function in patients with tremordominant and non-tremor-dominant Parkinson's disease, while deep brain stimulation targeting the globus pallidus externus can alter the temporal pattern of neural activity throughout the basal ganglia–thalamus network. Therefore, the comp
