User attitudes on privacy with respect to location data has been extensively studied. However, user attitudes of privacy in relation to proximity sensing is still lacking. We present the results from a survey conducted on users of a proximity sensing application we developed and diffused by handing out phones with the proximity sensing application pre-installed, with 31 respondents. The results co
OBJECTIVE: To explore changes in pain, spasticity, range of motion, activities of daily living, bowel and lower urinary tract function and quality of life of individuals with spinal cord injury following robotic exoskeleton gait training.DESIGN: Prospective, observational, open-label multicentre study.METHODS: Three training sessions per week for 8 weeks using an Ekso™ GT robotic exoskeleton (EKSO
The early molecular response to severe traumatic brain injury (TBI) was evaluated using biopsies of structurally normal-appearing cortex, obtained at location for intracranial pressure (ICP) monitoring, from 16 severe TBI patients. Mass spectrometry (MS; label free and stable isotope dimethyl labeling) quantitation proteomics showed a strikingly different molecular pattern in TBI in comparison to
Background: In spontaneous supratentorial intracerebral hemorrhage (ICH), the role of surgical treatment remains controversial, particularly in deep-seated ICHs. We hypothesized that early mortality and long-term functional outcome differ between patients with surgically treated lobar and deep-seated ICH. Method: Patients who underwent craniotomy for ICH evacuation from 2009 to 2015 were retrospec
The basic pathophysiology of TBI consists of an initial, primary injury including rapid deformation of brain tissue with destruction of brain parenchyma and blood vessels and acute loss of neuronal and glial cells. A key concept in the management of TBI is that not all cell death occurs at the time of primary injury; instead, a cascade of molecular and neurochemical secondary events occur during t
Traumatic brain injury (TBI) induces a marked systemic biochemical stress response with the release of several stress-related hormones including cortisol and the catecholamines. A major aim of using continuous sedation in the neurointensive care unit (NIC) unit is to attenuate the TBI-induced stress response via reduction of the cerebral energy metabolic demands. In the era of modern multimodality
BACKGROUND: We hypothesized that reduced cerebral blood flow (CBF) and/or energy metabolic disturbances exist in the tissue surrounding a surgically evacuated intracerebral hemorrhage (ICH). If present, such CBF and/or metabolic impairments may contribute to ongoing tissue injury and the modest clinical efficacy of ICH surgery.OBJECTIVE: To conduct an observational study of CBF and the energy meta
Traumatic brain injury (TBI) commonly results in injury to the components of the white matter tracts, causing post-injury cognitive deficits. The myelin-producing oligodendrocytes (OLs) are vulnerable to TBI, although may potentially be replaced by proliferating oligodendrocyte progenitor cells (OPCs). The cytokine interleukin-1β (IL-1β) is a key mediator of the complex inflammatory response, and
OBJECTIVE: To compare neurofilament light (NfL) and tau as blood-based biomarkers for acute sports-related concussion (SRC) and determine whether their concentrations at different time points after the injury are associated with prolonged time to return to play (RTP).METHODS: A total of 288 professional hockey players were followed longitudinally from September 1, 2012, to April 30, 2015. Data col
Intellectual property right (IPR) infringement has taken and increasingly takes place in the online environment, in particular on the internet, which has raised concerns on many different levels, and has led to a number of recent European initiatives. A number of legislative measures have been adopted at both international and European levels whose purposes are to strengthen and harmonise the prot
Social interaction sensing and indoor positioning using are widely researched. However, many use cases only need to determine proximity, and not the exact location. In this paper, we describe two methods to determine which meeting each user is participating in using proximity data collected from a challenging real-world office.We show that the RSSI threshold approach to detecting proximity is not
Cloud computing provides the illusion of infinite capacity to application developers. However, data center provisioning is complex and it is still necessary to handle the risk of capacity shortages. To handle capacity shortages, graceful degradation techniques sacrifice user experience for predictability. In all these cases, the decision making policy that determines the degradation interferes wit
Cigarette smoke is the most relevant risk factor for the development of lung cancer and chronic obstructive pulmonary disease. Many of its more than 4500 chemicals are highly reactive, thereby altering protein structure and function. Here, we used subcellular fractionation coupled to label-free quantitative MS to globally assess alterations in the proteome of different compartments of lung epithel
The chemical composition of calcium phosphate (CaP) materials for the regenerative therapy of large bone defects is similar to that of bone. Additionally, calcium phosphates show an excellent biocompatibility. Besides the support of defect healing calcium phosphate implants should be completely degraded within an adequate time period to be replaced by newly formed bone. Although degradation of CaP
Chronic lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), and idiopathic pulmonary fibrosis (IPF) are all characterized by structural changes of the airways and/or lungs that limit airflow and/or gas exchange. Currently, there is no therapy available that adequately targets the structural remodeling of the airways and lungs in these diseases. This underscores the great ne
Hydroxyapatite (HA) ceramic is a widely used synthetic bone substitute material for the regeneration of bone defects. We manufactured HA scaffolds with adjustable pore sizes and pore geometry by dispense-plotting. In addition, we attached peptides covalently onto the HA surface and are able to simultaneously quantify the amount of covalently attached and adsorbed peptide down to the picomolar rang
Medical doctors and nutritional specialists recommend to eat healthy foods including fruits and vegetables. Cosmetic experts also recommend to use cosmetic products obtained from natural products. The reason behind this is that natural products from plants contain chemical compounds which can promote health and protect our bodies from several diseases. These chemical compounds are called bioactiveBioactive compounds found in plants have been of interest to man since ancient times. These compounds have the ability to modulate the metabolic processes in our bodies, which suggests that they may promote better health. Bioactive compounds vary in their chemical structure, polarity, stability and biological activity. This diversity makes the study of bioactive compounds challenging from the pers
