2. 1. Clostridium difficile : epidemiology and antibiotic resistance

   Author : Torbjörn Norén; Erik Bäck; Lars G. Burman; Roland Möllby; Örebro universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Clostridium difficile; antibiotic resistance; epidemiology; Medicine; Medicin; Medicin; Medicine;

   Abstract : Clostridium difficile is a spore-forming toxin-producing intestinal bacterium abundant in soils and waters. This pathogen relies on increased growth by a disturbed intestinal microflora and the production of two cytotoxins, toxin A and toxin B, which may cause anything from mild self-limiting C. READ MORE

4. 2. Study of Resistance in Hepatitis C Virus Prior to Treatment with Direct Acting Antivirals

   Author : Midori Kjellin; Johan Lennerstrand; Nina Weis; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hepatitis C; HCV; DAA; RAS; resistance-associated substitution; baseline resistance; NS5A; NS3; SVR; Medical Virology; Medicinsk virologi; Mikrobiologi; Microbiology; Infektionssjukdomar; Infectious Diseases;

   Abstract : The rapid advancement of Hepatitis C (HCV) treatment presents a great challenge to clinicians in optimising therapy for their patients. Genotype (GT), efficacy, side-effects, drug combinations and treatment durations must be tailored to individual patients, considering comorbidities, degree of fibrosis, adherence and antiviral resistance.

   Abstract : Truck transport offers a versatile way to ship goods in regional, long haulage and urban applications. However, the heavy truck sector accounts for 6 % of total greenhouse gas emissions in the European Union. Therefore, there is a need for a substantial reduction of these emissions to secure the sustainability of Earth for future generations. READ MORE

6. 4. Mechanisms and Dynamics of Mecillinam Resistance in Escherichia coli

   Author : Elisabeth Thulin; Dan I Andersson; Laura Piddock; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mecillinam; Antibiotic resistance; Escherichia coli; Urinary tract infections; Fitness; Penicillin binding proteins; cysteine biosynthesis; Mikrobiologi; Microbiology;

   Abstract : The introduction of antibiotics in healthcare is one of the most important medical achievements with regard to reducing human morbidity and mortality. However, bacterial pathogens have acquired antibiotic resistance at an increasing rate, and due to a high prevalence of resistance to some antibiotics they can no longer be used therapeutically.

7. 5. Investigation of Aerodynamic Resistance of Rotating Wheels on Passenger Cars

   Author : Alexey Vdovin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wheel forces; ventilation resistance; rim design; aerodynamic moment; wheel aerodynamics;

   Abstract : With the current conditions of rising fuel prices and the toughening of environmental legislation for CO2 and other emission gases, vehicle manufacturers around the world are looking into the ways to make their vehicles more energy efficient and therefore more environmentally friendly. One of the ways to achieve this goal is to improve aerodynamic design of vehicles in order to decrease aerodynamic resistance forces. READ MORE
