1. 1. Cellular receptors for viruses with ocular tropism

   Författare :Emma C Nilsson; Niklas Arnberg; Eric J Kremer; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; picornavirus; receptors; antivirals; Virology; Virologi; molekylärbiologi; Molecular Biology; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

   Sammanfattning : Several viruses from different virus families are known to cause ocular infections, e.g. members of the Adenoviridae, Picornaviridae and the Herpesviridae families. These infections are spread by contact and in the case of adenoviruses (Ads) and picornaviruses they are also highly contagious. LÄS MER

3. 2. Muscarinic acetylcholine receptors : investigation of interactions with agonists and antagonists

   Författare :Britta Hedlund; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In the present investigation interactions of agonists and antagonists with the muscarinic acetylcholine receptor from rat cerebral cortex and rat ileum smooth muscle have been characterized.It is suggested that the binding of antagonist involves two sequential equilibria, an association reaction followed by isomerization of the receptor-antagonist complex.

4. 3. Angiotensin II Receptors in the Human Coronary Circulation and in Heart Failure

   Författare :Emil Pantev; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Heart Failure; Human Coronary Arteries; Angiotensin II; AT receptors;

   Sammanfattning : Angiotensin II (Ang II) is a potent vasoconstrictor that is implicated in the pathogenesis of hypertension, heart failure and atherosclerosis. In this thesis, the efficacy and safety of Ang II receptor blockers (ARB) were evaluated. LÄS MER

5. 4. Molecularly Imprinted Polymers at the Nanometric Scale: Synthetic Receptors for Chemical Sensors

   Författare :Anne-Sophie Belmont; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymer technology; Biokemisk teknik; Biochemical technology; Nanostructures; Synthetic Receptors; Optical Sensors; Molecular Imprinting; Polymer; Polymerteknik;

   Sammanfattning : In this thesis, polymerisation techniques or deposition methods have been developed permitting the creation of thin molecularly imprinted polymer (MIP) films or patterns and their interfacing with transducer surfaces for biosensor applications. The creation of ultra thin films has been achieved using two different techniques, spin-coating and in-situ polymerization of thin films of monomers containing a sacrificial polymeric porogen, and autoassembly of MIP nanoparticles with the aid of an associative linear polymer.

7. 5. Endothelin and angiotensin II receptors in human coronary arteries and bypass grafts - Alterations in cardiovascular disease

   Författare :Angelica Wackenfors; Lunds universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; vasoconstriction; receptors; cardiovascular disease; human; coronary arteries;

   Sammanfattning : Angiotensin II (Ang II) and endothelin-1 (ET-1) induce strong vasoconstriction via activation of receptors on vascular smooth muscle cells. In this thesis, the contractile Ang II and endothelin receptors were examined in endothelium-denuded human coronary arteries and in bypass grafts (the left internal mammary artery and the saphenous vein), with focus on receptor alterations in cardiovascular disease.
