A number of studies suggest that some features of essential tremor (ET) and Parkinson disease (PD) overlap. Besides tremor, also some cognitive features have been implicated in ET and PD. There is recent evidence that a common genetic mutation occurs in ET and PD. Saccadic eye movements could provide an easily quantifiable procedure to help in the differential diagnosis in early PD and ET. Being able to distinguish early on the two diseases may help in tailoring therapy. Cortical control of saccades and antisaccades as they pertain to the potential discrimination of PD and ET is reviewed. Imaging and electrophysiological studies are highlighted; however, there are still few studies. Hopefully this review will stimulate further research, in particular in the direction of differences and similarities in the neural circuits involved in PD and ET. 相似文献

OBJECTIVE: Induction of apoptosis in target cells is a key mechanism by which chemotherapy induces cell killing. We have established an in vitro system for determining the chemosensitivity of epithelial ovarian cancer cells to carboplatin and paclitaxel (Taxol). Practical assays to predict the likelihood of individual tumor sensitivity are needed to facilitate the choice of adequate treatment. We sought to determine whether epithelial ovarian cancer cells (EOC) collected from the ascites fluid of patients known to be clinically chemosensitive or chemoresistant to carboplatin and paclitaxel would show a similar response to chemotherapeutic drugs after in vitro treatment. METHODS: Thirteen patients with stage III and IV ovarian cancer treated with carboplatin and paclitaxel were studied. Caspase-3 activation was used as a surrogate marker for activation of chemotherapy-induced programmed cell death. We compared the in vitro apoptotic response to the clinical response of the patients from whom the tumor cells were isolated. Clinical sensitivity was defined as no evidence of disease recurrence for 6 months after optimal debulking surgery and completion of chemotherapy. RESULTS: Of seven chemosensitive patients, five cell samples treated in vitro had increased caspase-3 activity in response to both carboplatin and paclitaxel. Five of six chemoresistant cases did not show caspase-3 activity in response to only one or to neither agent. CONCLUSION: Quantifiable markers of apoptosis such as caspase-3 activation have the potential to predict the clinical response to chemotherapy. Application of this assay in clinical laboratories could optimize the potential for efficient treatment and avoid the toxicities of ineffective drugs. 相似文献

Anticoagulation is important in stroke prevention in patients with atrial fibrillation. Until recently, heparins and vitamin K antagonists were the only available therapy for stroke reduction in atrial fibrillation (AF) patients. Non-vitamin K antagonist oral anticoagulants (NOACs) including direct thrombin inhibitor (dabigatran) and direct factor Xa inhibitors (rivaroxaban, apixaban and edoxaban) are now available and offer new options for stroke prevention. This article reviews the available data on the use of NOACs for primary and secondary stroke prevention in AF patients and describes specific patient populations to guide clinician in making the informed decision regarding appropriate use of those agents. It also addresses the use of NOACs early after acute stroke and use of thrombolysis while on NOAC. 相似文献
