05) was observed for all of them. These findings suggest that CDBS of the subthalamic nucleus is efficient in reducing some of the effects of PD in these study tasks. At the same time, the dysfunctions found in several cortical areas, characteristic of PD, limited the effects of the CDBS. The results of this study suggest that CDBS of the subthalamic nucleus can modulate cognitive-motor aspects of PD.Management of acute stroke varies greatly within and between different countries. This study assesses the current practices of physicians in Lebanon routinely involved in ischemic stroke (IS) management. We conducted a prospective observational study of patients hospitalized at 8 different Lebanese hospitals in the period August 1, 2015 to July 31, 2016, with a diagnosis of acute stroke. Baseline characteristics and data on diagnostic studies, as well as treatments received during hospitalization and at discharge, were collected and analyzed. Two hundred and three strokes/transient ischemic attacks (TIAs) were recorded but only 173 patients (85%) with ischemic events were included in the study. The patients' mean age was 69.8±12.7 years. All underwent brain imaging (CT scan and/or MRI) on admission. All ISs were managed by a neurologist, and patient management included consultation of a cardiologist. Hypertension was the most prevalent risk factor (78.6%), followed by a current cigarette smoking habit (50.3%), diabetes mellitus (42.8%), hypercholesterolemia (39.9%), previous stroke or TIA (17.3%), and atrial fibrillation (14.7%). Only four patients (accounting for 2.5% of the ISs) received thrombolytic therapy. More than 89% of the patients were discharged on at least one anti-hypertensive drug, 89.2% on statins and 37.6% on antidiabetic medications. BGB324 More than 55% of patients were dependent at discharge, as shown by a modified Rankin Scale (mRS) score of 0-2, whereas 33% were independent (mRS score of 3-5). There are many challenges facing stroke care in Lebanon, and there is potential for improvement in this setting. Reperfusion therapy is still largely underused and remains a major challenge in achieving guideline-based reperfusion goals.Our aim was to evaluate the impact of a single bout of exercise, consisting of a gait training session with body weight support (BWS), on histone acetylation status (global histone H4 and H3 acetylation levels), brain-derived neurotrophic factor (BDNF) levels, and oxidative stress markers in peripheral blood of individuals with chronic spinal cord injury (SCI). We also set out to compare these responses with those recorded after gait training performed using a walker and with no BWS. The subjects (nearly all with an incomplete spinal cord lesion) were each submitted to two 60-minute experimental sessions on separate days with a 1- week wash-out period between the interventions. The order of the sessions was randomized. Blood samples were collected before and after each experimental trial for measurement of biomarkers. The histone acetylation status and BDNF levels remained unchanged after both interventions. After the treadmill training, the participants showed a strong increase in levels of oxidative stress markers [plasma advanced oxidation protein products (AOPPs), nitrite and thiobarbituric acid-reactive substances] without changes in antioxidant mediators. Instead, elevations in AOPP and nitrite concentrations, in addition to increased levels of glutathione and catalase activity, were found after the walker training. link2 A single bout of gait training, be it conducted on a treadmill with BWS or using a walker without BWS, is not able to alter BDNF levels and histone acetylation status in SCI patients. However, these trials can modulate oxidative stress parameters, seemingly in a protocol-dependent manner.Multiple sclerosis (MS) is a chronic disease of the central nervous system, characterized by demyelinization and axonal loss resulting, in 66% of cases, in upper limb motor impairment. The effects of constraint-induced movement therapy (CIMT) have recently been investigated in MS patients. The aim of this randomized single-blind pilot study was to assess the effects of CIMT on upper limb activity, specifically smoothness of movement, in patients affected by progressive MS. Patients affected by MS, and reporting reduced use primarily of one upper limb, were enrolled and randomly allocated to two different groups a CIMT group, where treatment was performed with the less affected limb immobilized by a splint, and a control group, submitted to intensive bi-manual treatment. All evaluations were performed at baseline (T0) and after two weeks of treatment (T1) by an operator unaware of the patients' allocation. The primary outcome was the difference in movement smoothness, measured by means of a bidimensional kinemkinematic evaluation demonstrated that the CIMT group showed a significant reduction of endpoint error and higher mean speed for the more affected arm; these data are in line with the significant improvements recorded on the HGS and 9HPT. Moreover, in the CIMT group, a non-significant worsening of muscle strength was recorded for the less affected upper limb.The Barthel Index (BI) is used in Italy to measure the severity of disability and to identify patients suitable for admission to rehabilitation units. The objective of this psychometric study was to validate the Italian version of the BI in a population of patients with Parkinson's disease (PD). The study was conducted at three neurological and rehabilitation centres in Rome, Italy. The BI was administered to outpatients with PD. The reliability of the scale was assessed using Cronbach's alpha for internal consistency; the intra-class correlation coefficient (ICC) was used to measure its intra- and inter-rater reliability. Pearson's correlation coefficient was calculated to evaluate its validity, comparing it with the Parkinson's disease Questionnaire (PDQ-39), the Italian version of the Geriatric Depression Scale (GDS), the Hospital Anxiety and Depression Scale (HADS), and the Short Form 36-Health Survey Questionnaire (SF-36). The BI was administered to 94 patients with PD. The psychometric properties measured were significant Cronbach's alpha was 0.866 and the ICC for intra- and inter-rater reliability was 0.998 and 0.993, respectively. Pearson's correlation coefficient showed good correlation with the PDQ-39, GDS, HADS and SF-36 (p less then 0.01). The BI is a valid and reliable tool for measuring disability in a PD population.In recent years, cognitive theories have increasingly influenced the approach to motor rehabilitation. The connection between different aspects of cognitive and motor function is increasingly documented, underlining the importance of developing rehabilitation projects that take cognitive aspects into account. The aim of this non-systematic review is to highlight the relationship between cognition and motion and, in the light of new rehabilitation technologies, to better define how aspects of cognition can affect motor rehabilitation.Seasonal environments vary in their amplitude of oscillation but the effects of this temporal heterogeneity for host-parasite coevolution are poorly understood. Here, we combined mathematical modelling and experimental evolution of a coevolving bacteria-phage interaction to show that the intensity of host-parasite coevolution peaked in environments that oscillate in their resource supply with intermediate amplitude. Our experimentally parameterized mathematical model explains that this pattern is primarily driven by the ecological effects of resource oscillations on host growth rates. Our findings suggest that in host-parasite systems where the host's but not the parasite's population growth dynamics are subject to seasonal forcing, the intensity of coevolution will peak at intermediate amplitudes but be constrained at extreme amplitudes of environmental oscillation.The coordination of the hypoxic response is attributed, in part, to hypoxia-inducible factor 1α (Hif-1α), a regulator of hypoxia-induced transcription. After the teleost-specific genome duplication, most teleost fishes lost the duplicate copy of Hif-1α, except species in the cyprinid lineage that retained both paralogues of Hif-1α (Hif1aa and Hif1ab). Little is known about the contribution of Hif-1α, and specifically of each paralogue, to hypoxia tolerance. Here, we examined hypoxia tolerance in wild-type (Hif1aa+/+ab+/+) and Hif-1α knockout lines (Hif1aa-/-; Hif1ab-/-; Hif1aa-/-ab-/-) of zebrafish (Danio rerio). Critical O2 tension (Pcrit; the partial pressure of oxygen (PO2) at which O2 consumption can no longer be maintained) and time to loss of equilibrium (LOE), two indices of hypoxia tolerance, were assessed in larvae and adults. Knockout of both paralogues significantly increased Pcrit (decreased hypoxia tolerance) in larval fish. Prior exposure of larvae to hypoxia decreased Pcrit in wild-type fish, an effect mediated by the Hif1aa paralogue. In adults, individuals with a knockout of either paralogue exhibited significantly decreased time to LOE but no difference in Pcrit. Together, these results demonstrate that in zebrafish, tolerance to hypoxia and improved hypoxia tolerance after pre-exposure to hypoxia (pre-conditioning) are mediated, at least in part, by Hif-1α.A number of tropical reefs have transitioned from coral to macroalgal dominance, but the role of macroalgal competition in coral decline is debated. There is a need to understand the relative roles of direct coral-algal effects versus indirect, microbially mediated effects shaping these interactions, as well as the relevant scales at which interactions operate under natural field, as opposed to laboratory, conditions. We conducted a manipulative field experiment investigating how direct contact versus close proximity (approx. 1.5 cm) with macroalgae (Galaxaura rugosa, Sargassum polycystum) impacted the growth, photosynthetic efficiency, and prokaryotic microbiome of the common Indo-Pacific coral Acropora millepora. Both coral growth and photosynthetic efficiency were suppressed when in direct contact with algae or their inert mimics--but not when in close proximity to corals without direct contact. Coral microbiomes were largely unaltered in composition, variability, or diversity regardless of treatment, although a few uncommon taxa differed in abundance among treatments. link3 Negative impacts of macroalgae were contact dependent, accounted for by physical structure alone and had minimal effects on coral microbiomes. The spatial constraints of these interactions have important implications for understanding and predicting benthic community dynamics as reefs degrade.Diving as a lifestyle has evolved on multiple occasions when air-breathing terrestrial animals invaded the aquatic realm, and diving performance shapes the ecology and behaviour of all air-breathing aquatic taxa, from small insects to great whales. Using the largest dataset yet assembled, we show that maximum dive duration increases predictably with body mass in both ectotherms and endotherms. Compared to endotherms, ectotherms can remain submerged for longer, but the mass scaling relationship for dive duration is much steeper in endotherms than in ectotherms. These differences in diving allometry can be fully explained by inherent differences between the two groups in their metabolic rate and how metabolism scales with body mass and temperature. Therefore, we suggest that similar constraints on oxygen storage and usage have shaped the evolutionary ecology of diving in all air-breathing animals, irrespective of their evolutionary history and metabolic mode. The steeper scaling relationship between body mass and dive duration in endotherms not only helps explain why the largest extant vertebrate divers are endothermic rather than ectothermic, but also fits well with the emerging consensus that large extinct tetrapod divers (e.
