An Approach to Analyze the Movements of the Arms while Walking using Wearable Wireless Devices

Abstract—Rhythmic movement of the arms while walking is an important feature of human gait. In this paper, we present an approach to analyze the movements of the arms while walking by using three wearable wireless devices placed around the torso. One of the devices is transmitter placed at the back and the other two are symmetrically placed receivers that record the power variation due to movement

Niche recycling through division-independent egress of hematopoietic stem cells

Hematopoietic stem cells (HSCs) are thought to reside in discrete niches through stable adhesion, yet previous studies have suggested that host HSCs can be replaced by transplanted donor HSCs, even in the absence of cytoreductive conditioning. To explain this apparent paradox, we calculated, through cell surface phenotyping and transplantation of unfractionated blood, that similar to 1-5% of the t

Global Optogenetic Activation of Inhibitory Interneurons during Epileptiform Activity.

Optogenetic techniques provide powerful tools for bidirectional control of neuronal activity and investigating alterations occurring in excitability disorders, such as epilepsy. In particular, the possibility to specifically activate by light-determined interneuron populations expressing channelrhodopsin-2 provides an unprecedented opportunity of exploring their contribution to physiological and p

Yersinia pestis Ail recruitment of C4b-binding protein leads to factor I- mediated inactivation of covalently and noncovalently bound C4b

The outer membrane protein Ail of Yersinia pestis mediates several virulence functions, including serum resistance. Here, we demonstrate that Ail binds C4b-binding protein (C4BP), the primary fluid-phase regulator of the classical and lectin pathways. Non-covalent binding of C4 and C4b to Ail was also observed. C4BP bound to Ail can act as a cofactor to the serine protease factor I (fI) in the cle

MyD88 Signaling Regulates Steady-State Migration of Intestinal CD103+ Dendritic Cells Independently of TNF-α and the Gut Microbiota.

Intestinal homeostasis and induction of systemic tolerance to fed Ags (i.e., oral tolerance) rely on the steady-state migration of small intestinal lamina propria dendritic cells (DCs) into draining mesenteric lymph nodes (MLN). The majority of these migratory DCs express the α integrin chain CD103, and in this study we demonstrate that the steady-state mobilization of CD103(+) DCs into the MLN is

INITIAL INSIGHTS INTO THE STRUCTURE-ACTIVITY RELATIONSHIPS OF AVIAN DEFENSINS.

Numerous β-defensins have been identified in birds and the potential use of these peptides as alternatives to antibiotics has been proposed, in particular to fight antibiotic-resistant and zoonotic bacterial species. Little is known about the mechanism of antibacterial activity of avian β-defensins (AvBDs), and the present work was carried out to obtain initial insights into the involvement of str

Effect of alpha-ketoglutarate given to pregnant sows on the development of the humerus and femur in newborns

Alpha-ketoglutarate (AKG) was given to pregnant sows every day starting from the 91(st) d of pregnancy to farrowing. At the same time control pregnant sows were treated in the same way with physiological saline (PhS). Newborn piglets from the experimental (AKG) and control (PhS) mothers were euthanised in 1 h after their birth, and the femora and humeri were isolated and frozen at -25 degrees C un

Housing-related control beliefs and independence in activities of daily living in very old age

Control beliefs, i.e. a person's perceived control over his or her own behaviour, are important predictors of psychological functioning in old age. The aim of this study is to examine the mediating effect of housing-related control beliefs on the relationship between housing accessibility and independence in activities of daily living (ADL). Moreover, cross-national differences in five European co

Molecular Characterization of the Interaction between Porins of Neisseria gonorrhoeae and C4b-Binding Protein.

Neisseria gonorrhoeae, the causative agent of gonorrhea, is a natural infection only in humans. The resistance of N. gonorrhoeae to normal human serum killing correlates with porin (Por)-mediated binding to the complement inhibitors C4b-binding protein (CUP). The entire binding site for both porin molecules resides within complement control protein domain 1 (CCPI) of C4BP. Only human and chimpanze

Lack of an association between Helicobacter infection and autoimmune hepatitis in children

An association between Helicobacter infection and autoimmune hepatitis (AIH) in children was investigated. The prevalence of antibodies to H. pylori did not differ between the AIH and the control group, (22% versus 14%), and antibodies to non-gastric Helicobacter were not detected in either group. H. pylori DNA was found in two AIH liver tissues, but Helicobacter was not cultured from any sample.

Detection of gastric Helicobacter species in free-ranging lynx (Lynx lynx) and red foxes (Vulpes vulpes) in Sweden

Specimens of gastric mucosa and liver of 25 free-ranging Eurasian lynx (Lynx lynx), and four red foxes (Vulpes vulpes) shot in Sweden during 1999-2000, were investigated for the presence of Helicobacter species. Histopathology, bacteriologic culture and urease test, Helicobacter genus-specific 16S rDNA PCR analysis, and DNA sequence analysis were applied. Numerous Helicobacter-like organisms were

Ionic binding of C3 to the human pathogen Moraxella catarrhalis is a unique mechanism for combating innate immunity

Moraxella catarrhalis ubiquitous surface proteins A1 and A2 (UspA1/A2) interfere with the classical pathway of the complement system by binding C4b-binding protein. In this study we demonstrate that M. catarrhalis UspA1 and A2 noncovalently and in a dose-dependent manner bind both the third component of complement (C3) from EDTA-treated serum and methylamine-treated C3. In contrast, related Moraxe

The domain of concern of Swedish occupational therapists in psychiatric care.

As a consequence of the development of psychiatric care in Sweden, occupational therapists have adapted their roles to changing practice settings. The aim of this study was to investigate the domain of concern of occupational therapists in psychiatric care, operationalized as perceived responsibilities. Furthermore, the relationships of the domain of concern to underlying theories and models, clin

Quality of life after stroke: well-being, life satisfaction, and subjective aspects of work.

Stroke incidence in those of working age has been reported to be increasing significantly, implying strong incentives for research concerning working ability after stroke. This study focused on differences in subjective aspects of work and dimensions of quality of life after having experienced stroke. Sixty-five persons answered a postal questionnaire. The median age at the time of the stroke was

Plastic wave propagation in ductile slabs subjected to dynamic buckling

Plastic wave propagation during dynamic buckling of ductile slabs is investigated numerically using a contour plot method (q-plot) showing contours of normalized effective plastic strain rate as a function of time and position. A non-linear finite element method is used to analyse the buckling problem of the elastic-viscoplastic slab. The contour plot method is quite sufficient to depict the overa
