1. 16. Microextraction by packed sorbent of drugs and peptides in biological fluids

   Författare :Seyed Mosayeb Daryanavard; Mohamed Abdel-Rehim; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEPS; Local anaesthetics drugs; Peptides; Analytical Chemistry; analytisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

   Sammanfattning : Sample preparation as the first step in an analytical procedure has an important role, particularly in bioanalysis, because of the complexity of biological samples (blood plasma and urine). Biological matrix such as plasma and blood contains proteins, organic and inorganic salts, acids, bases and various organic compounds with similar chemistry to the analytes of interest. LÄS MER

4. 18. On inflammatory cytokines and β-amyloid peptides in acute and chronic neurodegeneration

   Författare :Roya Tehranian; Gianluigi Forloni; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inflammation; Cytokines; Amyloid; Peptides; Nerve degeneration; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

   Sammanfattning : Insults to the brain as well as neurodegenerative diseases are known to elicit inflammatory responses. Inflammation in the brain can on one hand initiate processes that are harmful to the injured tissue and exacerbate the damage, leading to neuronal degeneration and glial activation, and on the other hand activate processes that may be necessary for repair mechanisms and regeneration.

5. 19. Defense-peptides against mycobacteria

   Författare :Charlotte M A Linde; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Antimicrobial peptides; NK-lysin; granulysin; PR-39; Mycobacterium;

   Sammanfattning : Several members of the genus Mycobacterium can cause serious infections in both man and animal. One of the world's most serious infectious diseases, tuberculosis, is caused by the pathogen Mycobacterium tuberculosis. Specific defense to tuberculosis/mycobacteriosis is dependent on the individual's ability to mount a proficient immune response. LÄS MER

7. 20. Cell-penetrating peptides and oligonucleotides : Design, uptake and therapeutic applications

   Författare :Andrés Muñoz-Alarcón; Ülo Langel; Sandrine Sagan; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptides; oligonucleotides; scavenger receptors; telomerase; gene therapy; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : Regulation of biological processes through the use of genetic elements is a central part of biological research and also holds great promise for future therapeutic applications. Oligonucleotides comprise a class of versatile biomolecules capable of modulating gene regulation. LÄS MER
