1. 21. Fishing the gene pool : Genetic structure, admixture and behavioural complexity in fisheries management

   Författare :Kim H. Berndt; Enhet akvatisk ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fisheries management; Fishery stock; Stock discrimination; Genetic structure; Genetic admixture; Admixture zone; Stock substructure; Phenotypic divergence; Gadus morhua; Salmo trutta;

   Sammanfattning : Prudent management of marine fish resources relies on separation and management of biologically meaningful groups of conspecifics, termed fishery stocks, often depicted as self-sustaining, spatiotemporally separated and demographically independent entities. Such stock discrimination has however proven challenging. LÄS MER

3. 22. Chromatin structure and histone modifications in gene regulation

   Författare :Carolina Åstrand; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : In the living cell, DNA is densely packed into a chromatin structure constituting nucleosomal arrays. One nucleosome core particle includes a disc shaped protein octamer consisting of pairs of histones H2A, H2B, H3 and H4. 146 bp of DNA is wrapped in almost two turns around this protein complex.

4. 23. Chimeric gene delivery vectors : Design, synthesis, and mechanisms from transcriptomics analysis

   Författare :Moataz Dowaidar; Ülo Langel; Sandrine Sagan; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptides; magnetic nanoparticles; graphene oxide; autophagy; siRNA; SCO; QSAR; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : Delivery of nucleic acid is a promising approach for genetic diseases/disorders. However, gene therapy using oligonucleotides (ONs) suffers from low transfection efficacy due to negative charges, weak cellular permeability, and enzymatic degradation. LÄS MER

5. 24. Streptococcal cell surface proteins : structure and gene characterisation

   Författare :Viatcheslav Katerov; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; mycology; virology; bacteriology; virologi; mykologi; Microbiology; bakteriologi;

   Sammanfattning : Streptococcus pyogenes (group A streptococci, GAS) is a potent human pathogen known to express a number of cell surface associated virulence factors. It is an established fact that these different surface proteins play an important role during infection. LÄS MER

7. 25. Ribosomal Stalk Protein L12 : Structure, Function and Application

   Författare :Chandra Sekhar Mandava; Suparna Sanyal; Knud Nierhaus; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome; protein synthesis; L12 dimer; initiation; elongation; G factors; and His-tag; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

   Sammanfattning : Ribosomal stalk proteins are known to play important role in protein synthesis. The ‘stalk’, an extended structure on the large subunit of the ribosome is composed mainly of two to three dimers of L12 and one L10 protein, which forms the base of the stalk. In E. LÄS MER
