Colorectal cancer (CRC) is a mortal disease due to treatment resistance, recurrence and distant metastasis. Emerging evidence has revealed that a small sub-population of cancer cells termed cancer stem cells (CSCs)/ cancer-initiating cells (CICs) is endowed with high levels of tumor-initiating ability, self-renewal ability and differentiation ability and is responsible for treatment resistance, recurrence and distant metastasis. Eradication of CSCs/CICs is essential to improve current treatments. However, the molecular mechanisms by which CSCs/CICs are maintained are still elusive...

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) reduces motor symptoms in most patients with Parkinson disease (PD), yet may produce untoward effects. Investigation of DBS effects requires accurate localization of the STN, which can be difficult to identify on magnetic resonance images collected with clinically available 3T scanners. The goal of this study is to develop a high-quality STN atlas that can be applied to standard 3T images. We created a high-definition STN atlas derived from seven older participants imaged at 7T...

The crustacean stomatogastric nervous system (STNS) is a well-known model for investigating neuropeptidergic control of rhythmic behavior. Among the peptides known to modulate the STNS are the C-type allatostatins (AST-Cs). In the lobster, Homarus americanus, three AST-Cs are known. Two of these, pQIRYHQCYFNPISCF (AST-C I) and GNGDGRLYWRCYFNAVSCF (AST-C III), have non-amidated C-termini, while the third, SYWKQCAFNAVSCFamide (AST-C II), is C-terminally amidated. Here, antibodies were generated against one of the non-amidated peptides (AST-C I) and against the amidated isoform (AST-C II)...

The concept of deep brain stimulation (DBS) for Parkinson's disease (PD) was introduced over 20 years ago, but our understanding of the nuances of this procedure continues to improve. The average motor outcomes of internal segment of the globus pallidus (GPi) and subthalamic nucleus (STN) DBS appear to be similar, although GPi DBS may allow greater recovery of verbal fluency and may provide greater relief of depression symptoms and improvement in the quality of life, and STN DBS appears more likely to result in decrease in levodopa equivalent doses...

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is the reference technique in Parkinson's disease (PD) at different stages of complications. Some patients cannot afford DBS due to anticoagulation or comorbidities or due to pecuniary reasons. Radiosurgery is a minimally invasive stereotactic technique, with no craniotomy and subsequently no risk of bleeding or infection. Its good safety efficacy profile has been established in the treatment of tremor, and the postoperative care issues are simple with a much shorter hospital stay (mean 48 h)...

This report summarizes the state-of-the-art and controversies around patient selection for deep brain stimulation (DBS) for various conditions. Parkinson's disease (PD): several class I studies have shown superiority of DBS over best medical treatment for advanced PD with fluctuations and further inclusion criteria. One class I study suggests that PD patients with early motor complications might gain more quality of life if operated within 3 years after the onset of fluctuations. The subthalamic nucleus (STN) is still the standard target...

BACKGROUND: Subthalamic nucleus deep brain stimulation (STN DBS) surgery is clinically effective for treatment of cervical dystonia; however, the underlying physiology has not been examined. We used transcranial magnetic stimulation (TMS) to examine the effects of STN DBS on sensorimotor integration, sensorimotor plasticity and motor cortex excitability, which are identified as the key pathophysiological features underlying dystonia. METHODS: TMS paradigms of short latency afferent inhibition (SAI) and long latency afferent inhibition (LAI) were used to examine the sensorimotor integration...

OBJECTIVE: Deep Brain Stimulation (DBS) is an effective surgical approach for treatment of Parkinson's disease (PD), dystonia and essential tremor (ET). Traditionally, DBS is performed using frame-based stereotactic technique. Recently, image guided surgery (IGS) using neuronavigation has gained popularity in neurosurgical procedures. We aim to investigate whether DBS using neuronavigation is capable of improving patient's outcome and minimize its complications. SUBJECT AND METHODS: From February 2011 to October 2016, 20 patients with PD and 6 patients with ET were enrolled in the study...
