    Abstract : Abstract Infectious diseases are a leading cause of death in sub-Saharan Africa, and in Rwanda diarrhea, lower respiratory and other common infections are linked to high mortality and morbidity. For children ... READ MORE

  2. 2. Avian Influenza Virus : Deciphering receptor interactions and their role in interspecies transmission

    Author : Per Eriksson; Patrik Ellström; Björn Olsen; Josef D. Järhult; Åke Lundkvist; Jonas Waldenström; Hans-Dieter Klenk; Uppsala universitet; []

    Abstract : Influenza A virus (IAV) annually infects approximately 5–15 % of the human population, causing ~500,000 deaths globally. Novel IAVs have emerged and spread pandemically in the human population, but have over time established endemic circulation with reduced pathogenicity causing seasonal influenza. The natural reservoir of IAVs is wild waterfowl. READ MORE

  3. 3. Automatic Virus Identification using TEM : Image Segmentation and Texture Analysis

    Author : Gustaf Kylberg; Ida-Maria Sintorn; Gunilla Borgefors; Walter Kropatsch; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; image processing; virus identification; transmission electron microscopy; texture analysis; texture descriptors; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Viruses and their morphology have been detected and studied with electron microscopy (EM) since the end of the 1930s. The technique has been vital for the discovery of new viruses and in establishing the virus taxonomy. Today, electron microscopy is an important technique in clinical diagnostics. READ MORE

  4. 4. Influenza A Virus : Spatial analysis of influenza genome trafficking and the evolution of the neuraminidase protein

    Author : Dan Dou; Robert Daniels; Martin Schwemmle; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Influenza A virus; IAV; neuraminidase; NA; IAV genome trafficking; viral entry; viral replication; co-infection; antigenic drift; antigenic shift; NA assembly; transmembrane domain; evolution; Biochemistry; biokemi;

    Abstract : Influenza A viruses (IAVs) are a common infectious agent that seasonally circulates within the human population that causes mild to severe acute respiratory infections. The severity of the infection is often related to how the virus has evolved with respect to the pre-existing immunity in the population. READ MORE

  5. 5. Virus Fate and Transport in Groundwater : Organic matter, uncertainty, and cold climate

    Author : Jean-Marc Mayotte; Keven Bishop; Stephan Köhler; Fritjof Fagerlund; Sven Halldin; Constantinos V. Chrysikopoulos; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; managed aquifer recharge; organic matter; virus; numerical modeling; uncertainty; Hydrology; Hydrologi; Mikrobiologi; Microbiology;

    Abstract : Water managers must balance the need for clean and safe drinking water with ever-increasing amounts of waste-water. A technique for treating and storing surface water called “managed aquifer recharge” (MAR) is frequently used to help maintain this balance. READ MORE
