   Sammanfattning : This work focuses on the design, synthesis, characterization, and application projections of low-coordinated heavy pnictogen-containing (described by the generic letter E, hence E=C) phosphaalkenes (P=C) and arsaalkenes (As=C), with emphasis on the E=C group motifs. The work aims to understand their functional and modular character, reactivity, and potential applications by stabilizing, isolating, and characterizing these species in low-coordination environments.

3. 17. Molecular design, synthesis and performance evaluation of phenothiazine-based small molecules for efficient organic solar cells

   Författare :Srikanth Revoju; Bertil Eliasson; Haining Tian; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic solar cell; small molecule donors; phenothiazine; power conversion efficiency; organisk kemi; Organic Chemistry;

   Sammanfattning : Photovoltaics offers one of the most promising routes to generate electricity in a clean way. As an emerging technology in photovoltaics, organic solar cells (OSC) have attracted a great deal of attention owing to their potential low-cost, lightweight, flexibility and solution processability.

4. 18. Functional characterization of the small antisense RNA MicA in Escherichia coli

   Författare :Klas Ifeanyi Udekwu; Gerhart Wagner; Tony Romeo; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small RNA; antisense; outer membrane; Hfq-dependence; RNase III; LuxS; Quorum sensing; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

   Sammanfattning : The Escherichia coli small RNA (sRNA) MicA was identified recently in a genomewide search for sRNAs. It is encoded between the genes gshA and luxS in E. coli and its close relatives. The function of sRNAs in bacteria is generally believed to be in maintenance of homeostasis via stress-induced modulation of gene expression. LÄS MER

5. 19. Targeting the GH/IGF-1 axis with novel, small molecule inhibitors

   Författare :Linda Rosengren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The growth hormone (GH) / insulin-like growth factor (IGF) family of ligands, binding proteins and receptors play multiple roles in cell growth, metabolism and development. In addition, numerous studies have demonstrated the pathophysiological importance of the GH/IGF-1 axis. LÄS MER

7. 20. Small-Molecule Galectin Ligands : Structure-Based Optimisation of Affinity and Selectivity

   Författare :Sjors Van Klaveren; Centrum för analys och syntes; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Galectins; structure activity relation;

   Sammanfattning : In the body, all cell surfaces are covered with glycans, and many regulatory components havecarbohydrates attached to them, which can aid in their function. Galectins are a family of proteins whichcan bind to specific glycans and oligosaccharides and cross-link them to influence a wide range of cellularprocesses. LÄS MER
