Here, we developed a novel in vitro co-culture model, in which process-bearing astrocytes and isolated cerebral microvessels from mice were co-cultured. Astrocytes formed contacts with microvessels from both adult and neonatal mice. However, concentrated localization of the immunofluorescence signal for aquaporin-4 (AQP4) at contact sites between perivascular endfoot processes and blood vessels was only detected with neonatal mouse microvessels. Contact between astrocytic processes and microvessels was retained, whereas concentrated localization of AQP4 signal at contact sites was lost, by knockdown of dystroglycan or α-syntrophin, reflecting polarized localization of AQP4 at perivascular regions in the brain...

Neural networking, including axon targeting and synapse formation, is the basis of various brain functions, including memory and learning. Diabetes-mellitus affects peripheral nerves and is known to cause fatty liver disease. Electron microscopy (EM) provides the resolution required to observe changes in fine subcellular structures caused by such physiological and pathological processes, but samples are observed in vacuum. Environmental capsule EM can directly observe cells in a more natural aqueous environment, but the size-limited capsules restrict cell culturability...

Manifestations of local tissue damage, such as hemorrhage and myonecrosis, are among the most dramatic effects of envenomation by viperid snakes. Snake venom metalloproteinases (SVMPs) of the P-III class are main players of the hemorrhagic effect due to their activities in promoting blood vessel disruption. Hemorrhagic Factor 3 (HF3), a P-III class SVMP from Bothrops jararaca, shows a minimum hemorrhagic dose of 240 fmol on rabbit skin. The aim of this study was to assess the effects of a sub-cytotoxic dose of HF3 (50 nM) on the proteomic profile of C2C12 differentiated cells (myotubes) in culture, and on the peptidomic profile of the culture supernatant...

INTRODUCTION: Type 2 diabetes mellitus (T2DM) and its complications are more common among Māori and Pacific people compared with other ethnic groups in New Zealand. Comprehensive and sustained approaches that address social determinants of health are required to address this condition, including culturally specific interventions. Currently, New Zealand has no comprehensive T2DM management programme for Māori or Pacific people. METHODS AND ANALYSIS: The Mana Tū programme was developed by a Māori-led collaborative of primary healthcare workers and researchers, and codesigned with whānau (patients and their families) in order to address this gap...

OBJECTIVES: The Canadian Diabetes Risk Assessment Questionnaire (CANRISK) is a validated, evidence-based, self-administered tool to assess the risk for type 2 diabetes mellitus in multiethnic Canadian adults. Identifying individuals at high risk for type 2 diabetes allows early intervention that improves modifiable risk factors. This study examined the risk factors for type 2 diabetes in multiethnic urban youth in Edmonton, Alberta. METHODS: An interviewer-administered questionnaire was developed based on CANRISK variables, such as age, gender, ethnicity, family history of diabetes, medical history of high blood sugar or high blood pressure, anthropometric measurements, physical activity and dietary intake...

The gold standard in microbiological diagnostics of bacteremia is a blood culture in automated systems. This method may take several days and has low sensitivity. New screening methods that could quickly reveal the presence of bacteria would be extremely useful. The objective of this study was to estimate the effectiveness of these methods with respect to blood cultures in the context of antibiotic therapy. Blood samples from 92 children with sepsis were analyzed. Blood cultures were carried out in standard automated systems...

Lactococcus garvieae is a well-known fish pathogen that has low virulence in humans and is rarely isolated from the blood cultures of endocarditis patients. We describe herein the first reported case of transfusion-transmitted L. garvieae sepsis caused by a contaminated platelet concentrate from a donor who consumed raw octopus before blood donation. Retrospective examination of the laboratory results of the index donor revealed that his haemoglobin levels had been steadily decreasing, which led to the detection of a latent colon cancer...
