Biography:

G.V. Anguelova completed her medical training in 2014 at the Leiden University Medical Centre. In 2012 she also obtained an engineering masters degree in Biomedical engineering (Biomechatronics) at the Technical University in Delft, The Netherlands. She is currently finishing her PhD thesis on Neonatal Brachial Plexus Palsy and is working as a neurology resident in Haaglanden Medisch Centrum in the Hague.

Abstract:

Neonatal Brachial Plexus Palsy (NBPP) may lead to permanent impairment of arm function. As NBPP occurs when central motor programs develop, these may be ill-formed. We studied elbow flexion and motor imagery with fMRI to search for abnormal motor programming. We compared the cortical activity of adults with conservatively treated NBPP to that of healthy individuals stratified for hand dominance, using fMRI BOLD tasks of elbow flexion and motor imagery of flexion. Additionally, resting-state networks and regional gray matter volume were studied. Sixteen adult NBPP patients (seven men; median age 29 years) and sixteen healthy subjects (seven men, median age 27 years) participated. Cortical activation was significantly higher in patients during flexion imagery compared to healthy individuals and it increased with lesion extent and muscle weakness. The contralateral and ipsilateral premotor cortex, and the contralateral motor cortex showed stronger activity during imagined flexion in the right-handed NBPP subjects compared to healthy individuals. Activity patterns during actual flexion did not differ between groups. No differences in resting-state network connectivity or gray matter amount were found between the groups. NBPP affected imagined but not actual elbow flexion, suggesting an impairment of motor planning which would indicate abnormal motor programming in NBPP.

Abstract:

During the study period, a total of 12 patients (10 males and 2 females, age from 27 to 76 years-old and symptoms persisted from 6 to 35 years) with ET were successfully underwent MRgFUS unilateral VIM thalamotomy (10 left VIMs and 2 right VIMs). All the enrolled patients were evaluated before the treatment and after with a clinical control of the treatment effectiveness. The target was defined real time with patient’s subjective statements during low power sonication. As a consequence, the treatment protocol was adapted by applying repetition of the final temperatures 56°C to 59°C. MRI showed thermal lesions on VIM in T2-weighted (T2w) images after sonication. All the ET treated patients who completed the procedure showed immediately free from  tremor , with no intra- or post operation severe permanent side effects.

 

CONCLUSIONS: 

This is the  first  experience in Taiwan of a unilateral thalamotomy using the MRgFUS. Our experience demonstrated the feasibility, safety, and accuracy of the  MRgFUS  thalamotomy in treating ET. In the treatment of movement disorders, the MRgFUS may be an alternative choice.

Abstract:

Antiplatelet therapy lowers the risk of recurrent stroke. Policosanol has shown to reduce platelet aggregation in experimental and clinical studies. This study investigated whether policosanol plus aspirin (AS) could improve the neurological outcome as compared to placebo + AS in patients with a recent ischemic stroke. Ninety-two (92) patients with a modified Rankin Scale score (mRSs) ≥2 - ≤4 after suffering an ischemic stroke within 30 days before enrolment were randomized to placebo or policosanol (20 mg/day) + aspirin (AS) (125 mg/day) (pla + AS or poli + AS) for 6 months. The primary efficacy variable was to obtain a better stroke outcome (mRSs ≤1) compared to pla +AS. Platelet aggregation was a secondary variable. After 12 and 24 weeks on therapy, the rates of poli + AS patients who achieved mRSs ≤1 were significantly (p<0.01 and p<0.00001, respectively) greater than in the pla + AS group. Poli + AS given for 6 weeks reduced significantly (p<0.00001 vs baseline, p<0.01 vs pla + AS) the mean mRSs values (24.1%), and this effect improved thereafter, so that reductions of 31.0% and 55.2% were found after 12 and 24 weeks, respectively. Also, poli + AS reduced significantly arachidonic acid- (41.0%) and ADP-induced (24.8%) platelet aggregation. Treatments were well tolerated. There were not withdrawals due to adverse experiences. In conclusion, poli added to standard AS treatment improved the neurological recovery as compared to pla + AS, and decreased platelet aggregation in patients with recent ischemic stroke.

Abstract:

Hypertension is a persistent raise of resting systolic (≥140 mmHg) and diastolic (≥90 mmHg) BP. In normal individuals BP ranges from 120/80 mmHg to 140/90 mmHg. Coronary Heart Diseases (CHD) develops more in diabetic hypertensives than in non-diabetics. CHD is the main cause of deaths worldwide. Management of hypertension has decreased the occurrence of stroke, heart failure and renal failure, however events of CHD has not been decreased to that level. On the contrary many antihypertensive drugs have diabetogenic effects via suppression of insulin. The purpose of the study was to observe effects of Lisinopril on insulin release by using rat isolated pancreas. Diazoxide was used as positive control i.e., known insulin suppressant drug. Dose used was based on therapeutic peak plasma concentration. Lisinopril at peak plasma level (150 ng/ml) did not inhibit insulin secretions significantly. In conclusion, at peak plasma level Lisinopril did not show any negative effect on insulin release.

Speaker
Biography:

Abbas Nikravesh has obtained his PhD from Karolinska Institutet in Stockholm, Sweden in 2008. He is an Assistant Professor in Molecular Genetics in North Khorasan University of Medical Sciences, Bojnurd, Iran. His interested research area is genetics of multiple sclerosis.

Abstract:

Multiple Sclerosis (MS) remains a poorly-understood autoimmune disease in the Central Nervous System (CNS) with unknown etiology and pathogenesis. Iranian population consisted of different ethnical groups with a specific history and genetic background having different prevalence of MS and responses to drugs. So, to find the role of genetic background on the expression of immunity-related genes, we are trying to evaluate the expression of STAT3, lnc-DC and THRIL in MS patients and healthy controls of two different ethnicities including Sistani population in the south-east and Kurmanj population in the northeast of Iran. To assess the effect of ethnicity on the expression levels of the immunity-related genes, blood samples were obtained from two different cohorts including Sistani and Kurmanj MS patients and their relevant controls. The expressions of the selected genes were assessed by real time PCR method. Surprisingly, in stratification for ethnicity, our results showed that although the expression level of THRIL significantly increased in Kurmanj MS patients (P=0.03), this lncRNA down regulated in Sistani patients (P=0.028) in comparison with their relative healthy controls. Moreover, lnc-DC did not show any significantly different expression in both Kurmanj (P=0.33) and Sistani patients (P=0.54). In conclusion, our results showed that besides the role of lncRNAs in the pathogenesis of MS through different mechanism, to be more successful in effective MS therapies based on personalized medicine, genetic background is an important factor which must to be considered.

Abstract:

Extracellular potassium ion concentration ([K]e) is tightly regulated throughout the brain because it has a major impact on brain functionality. Potassium concentration is disrupted in many brain diseases such as stroke and epilepsy. My project is designed base on a well-developed experimental platform to investigate the effects of extracellular potassium redistribution in physiological states. All experiments were conducted in vivo in mouse neocortex. 2 double-barreled K-sensitive electrodes coupled with Local Field Potential (LFP) electrodes were placed 4 mm apart. 50 mM KCl solution was injected focally closer to one of the K-LFP electrodes. [K]e levels and LFP were measured in two different scenarios: (1) Pharmacological intervention (gap junction blockage) and (2) optical intervention (optogentics). Focally increased [K]e was associated with a transient depolarization which in turn spreads into neighboring tissues so called spreading depolarization. Gap junctional blockade in the peri-injection site simultaneously increased the amplitude and duration of the local [K]e response and the local field response was greatly prolonged. While in the remote injection site, [K]e response was decreased after gap junctional blockage application. Optical stimulation decreased the [K]e both in the peri-injection and remote site. Our preliminary results are evidence of slow K redistribution (take for minutes) throughout the astrocytic syncytium which is partly mediated via astrocytic gap junctions. Potassium redistribution across a large area of the cortex is not a well-studied area because most tudies have limited their focus on focal potassium dynamics. In this project we are addressing this gap using novel tools to lucidate potassium redistribution dynamics.
