The founder principle, founder selection, and evolutionary divergence and convergence in natural populations of Philaenus
2009
Parts of the archipelago of the Baltic Sea are rising above the water level at a steady, slow rate. Plant species appear on the emerging islands in a definite order, and an early stage and a late stage can be distinguished in the development of meadows on the islands. In 1969–1973 four populations of Philaenus spumarius living in meadows at the early stage had widely different frequencies of the alleles determining colour polymorphism. In the same years three Philaenus populations living on islands with meadows at the late stage had closely similar allele frequencies. The differences between the Philaenus populations in the early stage meadows are ascribed partly to the founder principle an…
Seasonal Distribution and Movement of the Invasive Pest Delottococcus aberiae (Hemiptera: Pseudococcidae) Within Citrus Tree: Implications for Its In…
2018
[EN] Delottococcus aberiae (De Lotto) (Hemiptera: Pseudococcidae) is the most recent species of mealybug introduced to Spain that is affecting citrus. The feeding behavior of D. aberiae causes severe direct damage to citrus fruits, distorting their shape and/or causing reduction in size. There is no information available regarding its distribution within the citrus trees. The main objective of this study was to describe the seasonal distribution of D. aberiae within citrus trees and its migration patterns on the plants. Ten citrus orchards from eastern Spain were periodically sampled during 3 yr. In each orchard, the mealybug was sampled in different infested strata (canopy, trunk, and soil…
Outbreak of IMI-1 Carbapenemase-producing colistin-resistant Enterobacter cloacae on the French island of Mayotte (Indian Ocean)
2018
International audience; The spread of carbapenemase-producing Enterobacteriaceae in the Southwest Indian Ocean islands is poorly known. Here we describe an outbreak of colistin-resistant Enterobacter cloacae harbouring blaIMI-1 in the French overseas department of Mayotte. Between October 2015 and January 2017, all isolates of imipenem-non-susceptible E. cloacae at Mayotte Medical Center and University Hospital of Reunion Island were screened for carbapenemase production. Positive isolates were typed by pulsed-field gel electrophoresis and whole-genome sequencing (WGS)-based multilocus sequence typing (MLST), and all β-lactamase genes were identified by PCR and sequencing. Resistance profil…
Hand strengthening exercises in chronic stroke patients:Dose-response evaluation using electromyography
2016
Abstract Study Design Cross-sectional. Purpose of the Study This study evaluates finger flexion and extension strengthening exercises using elastic resistance in chronic stroke patients. Methods Eighteen stroke patients (mean age: 56.8 ± 7.6 years) with hemiparesis performed 3 consecutive repetitions of finger flexion and extension, using 3 different elastic resistance levels (easy, moderate, and hard). Surface electromyography was recorded from the flexor digitorum superficialis (FDS) and extensor digitorum (ED) muscles and normalized to the maximal electromyography of the non-paretic arm. Results Maximal grip strength was 39.2 (standard deviation: 12.5) and 7.8 kg (standard deviation: 9.4…
A new methodology based on functional principal component analysis tostudy postural stability post-stroke
2018
[EN] Background. A major goal in stroke rehabilitation is the establishment of more effective physical therapy techniques to recover postural stability. Functional Principal Component Analysis provides greater insight into recovery trends. However, when missing values exist, obtaining functional data presents some difficulties. The purpose of this study was to reveal an alternative technique for obtaining the Functional Principal Components without requiring the conversion to functional data beforehand and to investigate this methodology to determine the effect of specific physical therapy techniques in balance recovery trends in elderly subjects with hemiplegia post-stroke. Methods: A rand…
Functional electrical therapy for hemiparesis alleviates disability and enhances neuroplasticity
2011
Impaired motor and sensory function is common in the upper limb in humans after cerebrovascular stroke and it often remains as a permanent disability. Functional electrical stimulation therapy is known to enhance the motor function of the paretic hand; however, the mechanism of this enhancement is not known. We studied whether neural plasticity has a role in this therapy-induced enhancement of the hand motor function in 20 hemiparetic subjects with chronic stroke (age 53 ± 6 years; 7 females and 13 males; 10 with cerebral infarction and 10 with cerebral haemorrhage; and time since incident 2.4 ± 2.0 years). These subjects were randomized to functional electrical therapy or conventional phys…
Epidemiology and clonality of carbapenem-resistant Acinetobacter baumannii from an intensive care unit in Palermo, Italy
2012
Abstract Background Multidrug-resistant Acinetobacter baumannii, initially considered as having a poor clinical relevance, is frequently isolated from infection cases in intensive care units. We describe the epidemiology of carbapenem resistant A. baumannii (CRAB) in a general ICU in Palermo, Italy, from October 2010 to March 2011. Findings 58 of 61 isolates exhibited MICs for meropenem or imipenem ≥16 mg/L. Forty-nine carried blaOXA-23 and two blaOXA-58 genes. Five subtype clusters were detected by rep-PCR. Clusters D and E included 10 isolates that tested negative for the carbapenem resistance genes. MLST attributed all isolates, but two, with sequence type (ST)2, whereas the two remainin…
Gait reveals bilateral adaptation of motor control in patients with chronic unilateral stroke.
2008
Background and aims: Functional brain imaging has shown that bilateral brain reorganization may occur after unilateral cerebral damage. The present study searched for evidence of bilateral motor control changes in gait in patients with chronic unilateral stroke. Methods: Gait variables (temporal and spatial parameters, footprint peak times (FPPT) and footfall times (FFT)) were recorded in 48 patients with chronic unilateral stroke at their preferred speed, and in 10 healthy volunteers walking from very slowly to very fast on a pressure sensor walkway. The data were divided into 4 groups according to gait velocity. The functional outcome of stroke was measured by the Barthel Index. Results: …
Stimulation of the AT2 receptor reduced atherogenesis in ApoE−/−/AT1A−/− double knock out mice
2012
AT1 receptor blockers (ARB) and in part ACE inhibitors (ACI) potentially exert beneficial effects on atherogenesis independent of AT1 receptor inhibition. These pleiotropic effects might be related to angiotensin II mediated activation of the AT2 receptor. To analyze this hypothesis we investigated the development of atherosclerosis and the role of ACIs and ARBs in apolipoprotein E-deficient (ApoE(-/-)) mice and in ApoE/AT1A receptor double knockout mice (ApoE(-/-)/AT1A(-/-)). ApoE(-/-) mice and ApoE(-/-)/AT1A(-/-) mice were fed cholesterol-rich diet for 7 weeks. Vascular oxidative stress, endothelial dysfunction, and atherosclerotic lesion formation were evident in ApoE(-/-) mice, but were…
Zofenopril and Ramipril in Combination with Acetyl Salicylic Acid in Postmyocardial Infarction Patients with Left Ventricular Systolic Dysfunction: A…
2016
Summary Objective In the SMILE-4 study, zofenopril + acetyl salicylic acid (ASA) was more effective than ramipril + ASA on 1-year prevention of major cardiovascular events (MACE) in patients with acute myocardial infarction complicated by left ventricular dysfunction. In this retrospective analysis, we evaluated drug efficacy in subgroups of patients, according to a history of diabetes mellitus. Methods The primary study endpoint was 1-year combined occurrence of death or hospitalization for cardiovascular causes. Diabetes was defined according to medical history (previous known diagnosis). Results A total of 562 of 693 (81.0%) patients were classified as nondiabetics and 131 (18.9%) as dia…
