An Empirical Study of Open Government Data and its Use by Small and Medium-Sized Enterprises in Canada
… exists on the use of Open Government Data (OGD) by small and medium enterprises (SMEs). However, a few studies suggest that firms, including SMEs, can benefit from using OGD as a resource to stimulate growth and create value. This dissertation investigates the use of OGD by Canadian SMEs. …

The social impact of open government data
… the claim that open government data (OGD) should have a noticeable impact on marginalized groups’ inclusion in policy making. OGD researchers and practitioners conceptualize that society’s marginalized use OGD to achieve inclusion by overcoming information asymmetries and holding …

Open government data publication and use in a developing country: a case of Ghana
Implementing Open Government Data (OGD) increases a government's ability to share data on its activities with citizens in machine-readable formats. OGD improves citizen participation, transparency, accountability and creates impact. By permitting more transparency, OGD helps citizens monitor …

A Retrospective review of medical gastrointestinal endoscopy in children attending Red Cross War Memorial Children’s Hospital, Cape Town
… comprising 670 oesophagogastroduodenoscopies (OGD) and 103 colonoscopies. For OGD: 179 (26.7%), 287(42.8%) and 204 (30.4%) procedures were for diagnostic, therapeutic and follow - up indications. A total of 78 (10.1%) combined OGD/colonoscopy were carried out. Out of 103 total colonoscopies …

The role of L-carnitine in preventing mitochondrial dysfunction after neonatal hypoxia-ischemia
… for 2 hours prior to oxygen glucose deprivation (OGD). Under the same conditions we observed an LCAR induced decrease in both necrosis and mitochondrially-mediated apoptosis. To elucidate the mechanism for these data we studied the effect of LCAR on reactive oxygen species (ROS) before and after …

Astrocytes down-regulate microglial inflammatory responses
… were treated with oxygen-glucose deprivation (OGD) or hydrogen peroxide (H₂O₂, 0.01-1 mM), and culture conditioned media (OGDACM or H₂O₂-ACM) were collected. Both OGD-ACM and H₂O₂-ACM collected within 3 h after the treatment strongly reduced iNOS, COX-2, TNF-alpha, and IL-6 in interferon-γ …

Data for Housing Justice: Examining Activists’ Use of Open Government Data for Housing Justice in Boston, MA and New York, NY
… to public data through open government data (OGD) portals, from the local to national levels. The Organization for Economic Cooperation and Development describes OGD as a philosophy and a set of politics that aims to serve three social, political, and economic ends: transparency, …

Oxygen and Glucose Deprivation on Human Müller Cells (MIO-M1) and Human Organotypic Retinal Cultures (HORCs) in Relation to Glaucoma
… specifically oxygen and/or glucose deprivation (OGD) on the survival and genes expression of human Müller cells (MIO-M1), and retinal ganglion cells (RGCs) using the human organotypic retinal culture (HORC) model. Methods: MIO-M1 cells and HORCs were exposed to different levels of OGD using a …

Higher Brain Neurons Succumb to Acute Stroke-Like Insult While Lower Brain Neurons Strongly Resist
… slices from rat deprived of oxygen and glucose (OGD), we imaged anoxic depolarization (AD) as it propagates through these regions. AD, the initial electrophysiological event of stroke, is a depolarizing front that drains residual energy in compromised gray matter. The extent of AD reliably …

Causal mechanisms that enable institutionalisation of open government data in Kenya
Open Government Data (OGD) has become a topic of prominence during the last decade. However, most governments have not realized the desired outcomes from OGD, which implies that the envisaged value streams have not been realized. This study defines three objectives that will help address this …

Testing the Gliocentric Hypothesis of Brain Pathology
… was modelled using oxygen glucose deprivation (OGD). It was determined that astrocytes display regional differences in sensitivity to ischaemic insult. The most sensitive region was the dentate gyrus (DG), and corpus callosum (CC) was the least sensitive. Mature oligodendrocyte somas were found …

The Role of NADPH Oxidase in Ischemia/Reperfusion-Induced Alterations to AMPA Receptor Trafficking and NMDA Receptor Function
… oxygen-glucose deprivation/reperfusion (OGD/R) and the downstream redox-dependent signaling pathways leading to changes in NMDA and AMPA receptor function. In-vitro studies using differentiated SH-SY5Y human neuroblastoma cells were performed to test the hypothesis that NADPH …

Pathological mechanisms of the ischemic white matter injury in animal model of lacunar infarction
… more vulnerable to oxygen-glucose deprivation (OGD) than WT OLs. Applying TLR2 agonists after OGD substantially rescued WT OL death with augmentation of ERK1/2 phosphorylation. Treatment with TLR2 agonists also reduced the extent of ET-1 induced ischemic demyelination in vivowithout any increase …

Development of Techniques for Analysis of the Human Retinal Ganglion Cell Transcriptome: Application to the Role of Calcium in RGC Death in Glaucoma
… simulated ischemia (oxygen glucose deprivation, OGD) model in human organotypic retinal cultures (HORCs). Cell survival was measured by LDH, and RGC loss by immunohistochemistry and QRT-PCR. Western blot assessed proteases. Results: The sectioning technique developed enabled isolation of …

A Data Science Approach to Extracting Insights About Cities and Zones Using Open Government Data
… are referred to as Open Government Data (OGD) and are aimed at increasing the transparency and accountability of the US government. Our aim is to provide a well-defined procedure to process raw OGD information and produce expressive insights regarding different zones within a city, …
