Are activity limitations associated with lower urinary tract symptoms in stroke patients? A cross-sectional, clinical survey.

Objective . To assess self-reported activity limitations in a clinical sample of stroke patients and to identify their association with prevalence, severity and impact on daily life of lower urinary tract symptoms (LUTS). Material and methods . A cross-sectional, clinical survey was initiated whereby stroke patients were invited to complete four activity limitations measurements: Barthel Index, mo

A novel α-synuclein-GFP mouse model displays progressive motor impairment, olfactory dysfunction and accumulation of α-synuclein-GFP.

Compelling evidence suggests that accumulation and aggregation of alpha-synuclein (α-syn) contribute to the pathogenesis of Parkinson's disease (PD). Here, we describe a novel Bacterial Artificial Chromosome (BAC) transgenic model, in which we have expressed wild-type human α-syn fused to green fluorescent protein (GFP), under control of the mouse α-syn promoter. We observed a widespread and high

P-selectin glycoprotein ligand-1-mediated leukocyte recruitment regulates hepatocellular damage in acute obstructive cholestasis in mice.

OBJECTIVE: Leukocytes mediate hepatocellular injury in obstructive cholestasis. The aim of the present study was to define the role of P-selectin glycoprotein ligand-1 (PSGL-1) in cholestasis-induced leukocyte recruitment and liver damage. METHODS: C57BL/6 mice were pre-treated with an anti-PSGL-1 antibody or a control antibody prior to bile duct ligation (BDL) for 12 h. Hepatic recruitment of leu

Fructose affects enzymes involved in the synthesis and degradation of hypothalamic endocannabinoids.

Endocannabinoids have been implicated in the regulation of consumption of palatable food, sugar in particular. In this study, we investigated how palatable solutions would affect the hypothalamic mRNA expression of enzymes involved in the synthesis and degradation of the two main endocannabinoids, anandamide and 2-arachidonoyl-glycerol. Rats were offered sugar solutions to drink for one week, duri

Quantification of left to right shunt in patent ductus arteriosus by color doppler

Ultrasound is a reliable tool to diagnose patent ductus arteriosus in premature infants but no reliable noninvasive method exists to quantify ductal flow. The aim of this study was to quantify the size of the shunt via persistent ductus arteriosus from pixel counts in color Doppler flow images. A cotton band was placed around the ductus arteriosus of newborn lambs to adjust the magnitude of flow.

GABAergic Differentiation Induced by Mash1 Is Compromised by the bHLH Proteins Neurogenin2, NeuroD1, and NeuroD2.

During forebrain development, Mash1 directs gamma-aminobutyric acid (GABA)ergic neuron differentiation ventrally in the ganglionic eminences. Repression of Mash1 in the cortex is necessary to prevent the formation of GABAergic interneurons. Negative regulation of Mash1 has been attributed to members of the Neurogenin family; the genetic ablation of Neurogenin2 (Ngn2) leads to the derepression of M

Effect of Mucosal TRPV1 Inhibition in Allergic Rhinitis.

Transient receptor potential vanilloid-1 (TRPV1) has been implicated as a mediator of itch in allergic rhinitis. To address this possibility, we synthesized a TRPV1 blocker (SB-705498) for nasal administration in patients with seasonal allergic rhinitis. The pharmacological activity of SB-705498 was confirmed on human TRPV1-expressing HEK293 cells, using fluorometric calcium imaging, and in patien

Self-reported Walking Ability in Persons With Chronic Stroke and the Relationship With Gait Performance Tests.

OBJECTIVE: To assess self-reported walking ability in individuals with chronic stroke and to determine the relationship with gait performance tests. DESIGN: Descriptive analysis of a convenience sample. SETTING: A university hospital rehabilitation medicine clinic. PARTICIPANTS: Fifty ambulatory community-dwelling poststroke individuals (mean age, 64 years [range, 44-74 years] and mean t

Spectral signature of short attosecond pulse trains.

We report experimental measurements of high-order harmonic spectra generated in Ar using a carrier-envelope-offset (CEO) stabilized 12 fs, 800 nm laser field and a fraction (less than 10%) of its second harmonic. Additional spectral peaks are observed between the harmonic peaks, which are due to interferences between multiple pulses in the train. The position of these peaks varies with the CEO and

Computer Control of a Paper Machine : An Application of Linear Stochastic Control Theory

This paper describes an attempt to apply linear optimal control theory to computer control of an industrial process. The applicability of the theory is discussed. Particular attention is given to the problem of obtaining a mathematical model of process dynamics and disturbances. Results of actual measurements as well as results from on-line control experience are presented.

Evaluation of quantitative planar (90)Y bremsstrahlung whole-body imaging.

With high-dose administration of (90)Y labeled antibodies, it is possible to image (90)Y without an admixture of (111)In. We have earlier shown that it is possible to perform quantitative (90)Y bremsstrahlung SPECT for dosimetry purposes with reasonable accuracy. However, whole-body (WB) activity quantification with the conjugate view method is not as time consuming as SPECT and has been the metho

Glaucoma management in Sweden - results from a nationwide survey.

Purpose: To report the results from a nationwide survey on glaucoma management in Sweden, performed as a part of an Open Angle Glaucoma project conducted by the Swedish Council on Health Technology Assessment 2004-2008. Methods: In 2005, a survey was distributed to all providers of glaucoma care in Sweden: public eye departments, public outpatient departments and private practices. The questionnai

Central Role of Rho Kinase in Lipopolysaccharide-Induced Platelet Capture on Venous Endothelium.

BACKGROUND:: Platelet-endothelial cell interactions play a key role in hemostasis and pathological coagulation and are dependent on different surface molecules that are expressed upon activation (eg, mediated by lipopolysaccharide [LPS]). Recently, we have shown that Rho kinase plays a central role in LPS-mediated leukocyte-endothelial cell interactions. We investigated the role of Rho-kinase in i

Electron correlation: keeping close to an orbital description

This article deals with excited-state properties and spectroscopies which probe them. We argue that the orbitals obtained in local density theory form an excellent basis for discussing excited states and that the self-energy operator (or optical potential) associated with one-electron-type excited states is closely diagonal in such a basis. This diagonality often leads to considerable simplificati

Histidine-rich glycoprotein promotes bacterial entrapment in clots and decreases mortality in a mouse model of sepsis.

Streptococcus pyogenes is a significant bacterial pathogen in humans. In this study, Histidine-rich glycoprotein (HRG), an abundant plasma protein, was found to kill S. pyogenes. Furthermore, S. pyogenes grew more efficiently in HRG deficient plasma, and clots formed in this plasma were significantly less effective at bacterial entrapment and killing. HRG deficient mice were strikingly more suscep

p38 Mitogen-activated protein kinase signaling regulates streptococcal M1 protein-induced neutrophil activation and lung injury.

M1 serotype of Streptococcus pyogenes can cause STSS and acute lung damage. Herein, the purpose was to define the role of p38 MAPK signaling in M1 protein-induced pulmonary injury. Male C57BL/6 mice were treated with specific p38 MAPK inhibitors (SB 239063 and SKF 86002) prior to M1 protein challenge. Edema, neutrophil infiltration, and CXC chemokines were determined in the lung, 4 h after M1 prot
