1. 6. Structural basis of modulation by pH and calcium in a ligand-gated ion channel

   University essay from KTH/Genteknologi

   Author : Olivia Andén; [2021]
   Keywords : Pentameric ligand-gated ion channels; bacterial homolog; protein expression; protein purification; cryo-electron microscopy; data processing; protein structure; Pentamerisk ligandstyrd jonkanal; bakteriell homolog; proteinexpression; proteinrening; kryo-elektronmikroskopi;

   Abstract : Pentameriska ligandstyrda jonkanaler (pLGICs) är avgörande för omvandlingen av kemisk till elektrisk signalöverföring i djurs nervsystem. Dysfunktion i dessa kanaler har visat sig vara kopplad till flera sjukdomar inklusive epilepsi, schizofreni, Alzheimers och autism, vilket gör dem till en måltavla för en mängd olika läkemedel.

3. 7. Coral Fungia fungites- associated microbial communities and their shifts upon anthropogenic disturbances

   University essay from Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : VASILIKI PAPAZACHARIOU; [2019]
   Keywords : coral microbiome; Fungia fungites; Microbiology; corals; antibiotics; 16S;

   Abstract : One of the main focus of coral reef ecology has been to shed light on the importance of all microbial members of coral holobiont and how their interactions contribute to the coral’s resilience. However, knowledge is lacking about the composition of microbial communities inhabiting the surface mucus layer of corals including Fungia fungites, a species that lives under stressful conditions close to fish farms in Vietnam.

   Abstract : This report summarizes the work on the cloning, expression, and purification of PerR, a metal sensing regulator from Saccharopolyspora erythraea and the subsequent characterization using small angle X-ray scattering and other biochemical methods. The report aims to provide an insight into prokaryotic metal homeostasis, provide a better understanding of how PerR works and provide valuable information for the continued work on the crystallization of PerR.

5. 9. Prokaryotic expression of human complement regulator factor H domains and their interaction withPneumococcal surface protein PspC

   University essay from KTH/Skolan för bioteknologi (BIO)

   Author : Nils Lindström; [2017]
   Keywords : complement regulator; factor H; Pneumococci; interaction; E.coli; surface protein; PspC;

   Abstract : One of the oldest and most exciting questions in science is: are we alone in the universe? During the last four billion years of Earth’s history, countless organisms have inhabited almost every environmental niche on the planet, from the deepest sea to driest deserts. However, so far no extraterrestrial life has been found. READ MORE

6. 10. Isolation and Identification of Lactic Acid Bacteria from Swedish Foods

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Gim Minchul; [2015]
   Keywords : Lactic acid bacteria; Fermentation; Swedish foods;

   Abstract : Food fermentation is a method widely used in the past to extend the storage life of food. Numerous studies on fermented food have revealed that they not only have biopreservative properties but also health benefits. READ MORE
