2. 1. Photochemical and Photoelectric Applications of II-VI Semiconductor Nanomaterials

   Author : Abhilash Sugunan; Mamoun Muhammed; Lars Kloo; KTH; []
   Keywords : ZnO; Nanowire arrays; Photocatalysis; Nanofibers; CdTe; Nanotetrapods; Ostwalds ripening; Photoconduction; Nano-gap electrodes;

   Abstract : In this work we investigated fabrication of semiconductor nanomaterials and evaluated their potential for photo-chemical and photovoltaic applications. We investigated two different II-VI semiconductor nanomaterial systems; (i) ZnO oriented nanowire arrays non-epitaxially grown from a substrate; and (ii) colloidal CdTe nanotetrapods synthesized by solution-based thermal decomposition of organo-metallic precursors.

5. 3. Transcriptional and post-transcriptional regulation of telomerase reverse transcriptase (hTERT) expression : the role of histone modification and alternative splicing

   Author : Zheng Ge; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Telomerase, an RNA-dependent DNA polymerase responsible for telomeric DNA elongation, is silent in most normal differentiated human cells due to the tight repression of its catalytic unit, telomerase reverse transcriptase (hTERT), whereas constitutive hTERT expression and telomerase activation are prerequisites for cellular immortalization/malignant transformation. As reconfiguration of chromatin acts like a master on/off switch, determining whether particular genes are active or inactive, the project was specifically designed to first elucidate molecular strategies that integrate diverse signalling pathways at the hTERT chromatin and consequently result in telomerase activation or repression in normal and malignant human cells.

6. 4. Quantitation of gluconeogenesis in humans

   Author : Karin Ekberg; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Gluconeogenesis; mass isotopomer distribution analysis; deuteratedwater; hexamethylenetetramine; splanchnic and renal glucose production;

   Abstract : Several methods have been introduced for estimating gluconeogenesis, but none provides a direct measurement without assumptions that condition the accuracy of the estimate. The aim of this work has been to develop a new method for quantitative studies of gluconeogenesis, applicable in humans. READ MORE
