   Sammanfattning : Snus is a smokeless tobacco product made of a moist powder of ground tobacco. It is used mainly in the Nordic countries, although increasingly popular internationally. The Swedish snus tradition dates back to the seventeenth century, and it is now used daily by about 23% of the male and 6% of the female population. LÄS MER

3. 12. Asthma, chronic bronchitis and respiratory symptoms : prevalence and important determinants

   Författare :Bo Lundbäck; Jacob Boe; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; chronic bronchitis; epidemiology; prevalence; determinants;

   Sammanfattning : The Obstructive Lung Disease in Northern Sweden study's (OLIN) overall aim is prevention of obstructive airways diseases; asthma, chronic bronchitis and chronic obstructive pulmonary disease (COPD). The first part of the OLIN study was a cross- sectional study in three phases, which aimed to estimate the prevalence obstructive lung diseases and to collect data on possible determinants of diseases.

4. 13. Dosimetry and radiation quality in fast-neutron radiation therapy : A study of radiation quality and basic dosimetric properties of fast-neutrons for external beam radiotherapy and problems associated with corrections of measured charged particle cross-sections

   Författare :Jonas Söderberg; Gudrun Alm Carlsson; Crister Ceberg; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neutron; Dosimetry; Radiotherapy; Monte Carlo; Microdosimetry; Cross-section; RBE; LET; Energy-loss corrections; Radiological physics; Radiofysik;

   Sammanfattning : The dosimetric properties of fast-neutron beams with energies ≤80 MeV were explored using Monte Carlo techniques. Taking into account transport of all relevant types of released charged particles (electrons, protons, deuterons, tritons, 3He and α particles) pencil-beam dose distributions were derived and used to calculate absorbed dose distributions.

5. 14. Microgel Interactions with Peptides and Proteins : Consequence of Peptide and Microgel Properties

   Författare :Ronja Widenbring; Martin Malmsten; Per Hansson; Catherine Picart; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Binding; Degradation; Enzyme; Gel; Hydrogel; Microgel; Peptide; Protein; Release; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

   Sammanfattning : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.

7. 15. Extracellular matrix mimetic multi-functional scaffolds for tissue engineering and biomedical applications

   Författare :Ranjithkumar Ravichandran; Jaywant Phopase; Anthony Turner; Ann-Christine Albertsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Regeneration of functional tissues or complex organs via the combination of viable cells, biomimetic scaffolds, morphogenic factors, and external biophysical cues are the principle aims of Tissue Engineering (TE). TE relies on the use of artificial 3D scaffolds that can mimic the microenvironment of native tissue to harness the regenerative potential of cells. LÄS MER
