Variante cambial en tallos de Ipomoea (Convolvulaceae) nativas de Argentina.
Authors: Delbón Natalia , Sánchez Agustina , Cosa María Teresa 
Published: August 2018

Ipomoea es un género diversificado y complejo, compuesto por herbáceas, lianas y enredaderas leñosas, y un pequeño grupo de arbustos y árboles. Llama la atención que todas las especies estudiadas anteriormente presentaron diferentes tipos de variante cambial en sus tallos, independientemente del modo de vida, excepto dos taxones con crecimiento secundario normal, una liana y un árbol. Por ello, en el presente trabajo se planteó el estudio de tres enredaderas nativas de Argentina, Ipomoea cairica, I. purpurea e I. rubriflora, y de I. carnea ssp. fistulosa, árbol con crecimientonormal, con el fin de comparar el desarrollo de sus tallos y aportar datos de interés para dilucidar sus relaciones filogenéticas. Las cuatro especies estudiadas presentaron igual ontogenia y anatomía desus tallos con crecimiento primario, lo que apoyaría sus estrechas relaciones filogenéticas. Por otro lado, las enredaderas presentaron sólo dos tipos de variante cambial, el patrón lobado y el de cámbiumsupernumerario. Se puede inferir que en Ipomoea el tipo de crecimiento secundario, así como los tipos de variante cambial, no estarían directamente relacionados con el hábito; sin embargo, otras características del leño pueden ponerse a consideración como la proporción de tejido parenquimático y características de los vasos.

Published: August 2018

This study aims to explain the effect of inlet position of a Slow Sand Filter (SSF) Pipe on the amount of pollutant particles caught along the flow path in the SSF Pipe. The main equipment used is nine pieces of SSF Pipe, each has 4 inches in diameter and 50 cm in length with Pantai Panjang Bengkulu’ssand as the filter medium. The inlet positions tested were 90°, 45° and 0°; repeated three times and arranged in a completely randomized design (CRD). The observed variable is the weight of the captured pollutant in the SSF at the distance of 10cm, 20cm, 30cm, and 40cm from the inlet. Results of the research showed that the number of pollutant particles caught along the flow path in the SSF decreased following a linear model as the distance from the inlet was increased. The number of pollutant particles caught also decreased with the decrease of inlet position slope. The inlet position significantly affected the number of pollutant particles caught along the flow path; the position of 90° causes the highest amount of pollutants to be caught and significantly differs from that of the position of 45° and 0°. The position of 0° causes the least amount of pollutants to be captured that considered to be the best inlet position so far. It is important; however, to research whether inlet position of more than 180° could result in a much smaller amount of pollutant caught along the flow in the SSF Pipe.Keywords: SSFPipe, inlet position, particle caught in SSF, peat water filtration

Published: August 2018

OBJECTIVEThe aim of this study was to determine whether a modified registration method could reduce registration error and postoperative electrode vector error and to analyze the method’s clinical significance in deep brain stimulation (DBS) surgery.METHODSThe first part of the study involved a skull model, in which three registration methods were tested using the ROSA (robotic stereotactic assistance) system. In the second part, four registration methods were clinically tested in patients undergoing DBS surgery using the ROSA system. Thirty-three patients (65 sides, group I) underwent the conventional registration method 2E, and registration errors were recorded. Thirty-eight patients (75 sides, group II) underwent four types of modified registration methods including 2A, 2B, 2C, and 2D. Registration and electrode vector errors, intraoperative electrophysiological signal length (IESL), and DBS power-on voltage were recorded. The primary measure of efficacy was the change in the Unified Parkinson’s Disease Rating Scale (UPDRS) and UPDRS Part III scores from baseline to 10 weeks after surgery.RESULTSIn the skull model, the registration error (mean ± SD) was 0.56 ± 0.11 mm for method 1A, 0.35 ± 0.11 mm for method 1B (vs. 1A, p < 0.001), and 0.90 ± 0.15 mm for method 1C (vs. 1A, p < 0.001). In the clinical study, method 2C was selected for DBS surgery in group II since it had the smallest registration error among the four methods tested. The registration error was 0.62 ± 0.22 mm (mean ± SD) for group I and 0.27 ± 0.07 mm for group II (p < 0.001). Postoperative electrode vector error was 0.97 ± 0.31 mm for group I and 0.65 ± 0.23 mm for group II (p < 0.001). There was a positive correlation between registration error and electrode vector error in both groups (group I: r = 0.69, p < 0.001; group II: r = 0.71, p < 0.001). The mean IESL was 5.0 ± 0.9 mm in group I and 5.8 ± 0.7 mm in group II (p < 0.001). The mean DBS power-on voltage was 1.63 ± 0.44 V in group I and 1.48 ± 0.38 V in group II (p = 0.027). In the UPDRS score, group I showed 50% ± 16% improvement and group II showed 52% ± 18% improvement (p = 0.724); there was no statistically significant difference in improvement on the UPDRS.CONCLUSIONSIn DBS surgery assisted by the ROSA system, registration error and electrode vector error showed a positive correlation. The modified registration method could reduce the registration error and electrode vector error, but the long-term effects need to be further observed and evaluated.
Differences in functional connectivity profiles as a predictor of response to anterior thalamic nucleus deep brain stimulation for epilepsy: a hypothesis for the mechanism of action and a potential biomarker for outcomes

Published: August 2018

OBJECTIVEDeep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) is a promising therapy for refractory epilepsy. Unfortunately, the variability in outcomes from ANT DBS is not fully understood. In this pilot study, the authors assess potential differences in functional connectivity related to the volume of tissue activated (VTA) in ANT DBS responders and nonresponders as a means for better understanding the mechanism of action and potentially improving DBS targeting.METHODSThis retrospective analysis consisted of 6 patients who underwent ANT DBS for refractory epilepsy. Patients were classified as responders (n = 3) if their seizure frequency decreased by at least 50%. The DBS electrodes were localized postoperatively and VTAs were computationally generated based on DBS programming settings. VTAs were used as seed points for resting-state functional MRI connectivity analysis performed using a control dataset. Differences in cortical connectivity to the VTA were assessed between the responder and nonresponder groups.RESULTSThe ANT DBS responders showed greater positive connectivity with the default mode network compared to nonresponders, including the posterior cingulate cortex, medial prefrontal cortex, inferior parietal lobule, and precuneus. Interestingly, there was also a consistent anticorrelation with the hippocampus seen in responders that was not present in nonresponders.CONCLUSIONSBased on their pilot study, the authors observed that successful ANT DBS in patients with epilepsy produces increased connectivity in the default mode network, which the authors hypothesize increases the threshold for seizure propagation. Additionally, an inhibitory effect on the hippocampus mediated through increased hippocampal γ-aminobutyric acid (GABA) concentration may contribute to seizure suppression. Future studies are planned to confirm these findings.
Deep brain stimulation of the cerebellum for poststroke motor rehabilitation: from laboratory to clinical trial
Authors: Wathen Connor A. , Frizon Leonardo A. , Maiti Tanmoy K. , Baker Kenneth B. , Machado Andre G. 
Published: August 2018

Ischemic stroke is a leading cause of disability worldwide, with profound economic costs. Poststroke motor impairment is the most commonly encountered deficit resulting in significant disability and is the primary driver of stroke-associated healthcare expenditures. Although many patients derive some degree of benefit from physical rehabilitation, a significant proportion continue to suffer from persistent motor impairment. Noninvasive brain stimulation, vagal nerve stimulation, epidural cortical stimulation, and deep brain stimulation (DBS) have all been studied as potential modalities to improve upon the benefits derived from physical therapy alone. These neuromodulatory therapies aim primarily to augment neuroplasticity and drive functional reorganization of the surviving perilesional cortex.The authors have proposed a novel and emerging therapeutic approach based on cerebellar DBS targeted at the dentate nucleus. Their rationale is based on the extensive reciprocal connectivity between the dentate nucleus and wide swaths of cerebral cortex via the dentatothalamocortical and corticopontocerebellar tracts, as well as the known limitations to motor rehabilitation imposed by crossed cerebellar diaschisis. Preclinical studies in rodent models of ischemic stroke have shown that cerebellar DBS promotes functional recovery in a frequency-dependent manner, with the most substantial benefits of the therapy noted at 30-Hz stimulation. The improvements in motor function are paralleled by increased expression of markers of synaptic plasticity, synaptogenesis, and neurogenesis in the perilesional cortex. Given the findings of preclinical studies, a first-in-human trial, Electrical Stimulation of the Dentate Nucleus Area (EDEN) for Improvement of Upper Extremity Hemiparesis Due to Ischemic Stroke: A Safety and Feasibility Study, commenced in 2016. Although the existing preclinical evidence is promising, the results of this Phase I trial and subsequent clinical trials will be necessary to determine the future applicability of this therapy.

Authors: Arora Karan , Hanson Kristine T. , Habermann Elizabeth B. , Tollefson Matthew K. , Psutka Sarah P. 
Published: August 2018

Introduction and Objective: Conflicting data exists regarding the impact of body mass index (BMI) on postoperative outcomes following surgery for renal malignancies (RM). Herein, we investigated associations between obesity, hypoalbuminemia, and/or significant weight loss in the preoperative period, and risk complications and mortality within 30 days of radical (RN) or partial nephrectomy (PN). Materials and Methods: Review of the American College of Surgeons National Surgical Quality Improvement Program database identified 8,618 patients treated with PN or RN for RM between 2005 and 2012. Univariate and multivariable logistic regression models were developed to assess associations between hypoalbuminemia (<3.5 g/dl), >10% weight loss within 6 months of surgery, obesity (BMI >30 kg/m2), and 30-day major complications and mortality. Results: Median BMI was 29.2 kg/m2 with 24.9%, 11.9%, and 8.2% having class I, II, and III obesity, respectively. Weight loss of >10% was observed in 2.6% and 15.4% had preoperative albumin<3.5 g/dl. There were 1,802 complications (20.9%) and 88 deaths within 30 days (1.0%). On multivariable analysis, BMI ≥40 kg/m2 (OR 1.3, p = 0.04), >10% weight loss (OR 1.9, p < 0.001) and hypoalbuminemia (OR 1.5, p < 0.001) were independently associated with 30-day complications, while only >10% weight loss was independently associated with 30-day mortality (OR 2.4, p = 0.03). Conclusions: Extreme obesity, hypoalbuminemia, and significant weight loss were independently associated with risk of significant complications following PN or RN while only significant preoperative weight loss was associated with early mortality, underscoring the need to further understand the utility of moderating these risk factors in the perioperative period.
