   Sammanfattning : Hydrogen, as a clean energy carrier, burns without producing any carbon emissions. Hydrogen internal combustion engines (H2-ICE) are considered an alternative for the transition from conventional fossil-fuel vehicles. LÄS MER

3. 12. Islet Amyloid Polypeptide: Interaction with Amyloid Beta, Alpha-Synuclein and BRICHOS

   Sammanfattning :  Amyloid, the congophilic deposits of misfolded protein, are pathological hallmarks of many common diseases, among others, Alzheimer’s disease (AD), Parkinson’s disease (PD), and type 2 diabetes (T2D). Amyloid beta (Aβ) forms senile plaques in AD, alpha-synuclein (aSyn) forms Lewy bodies and Lewy neurites in PD, islet amyloid polypeptide (IAPP) forms islet amyloid in T2D. LÄS MER

4. 13. Genetics of Parkinson's disease - with focus on genes of relevance for inflammation and dopamine neruon development

   Sammanfattning : Abstract GENETICS OF PARKINSON’S DISEASE - WITH FOCUS ON GENES OF RELEVANCE FOR INFLAMMATION AND DOPAMINE NEURON DEVELOPMENT Introduction: The risk to be affected by Parkinson’s disease (PD) is considered to be influenced by genetic factors. In some rare cases of familial PD, mutations in some specific genes are known to cause the disease, but in the more common sporadic form of PD the causes are probably environmental factors interacting with genetic vulnerability.

5. 14. Covariate Model Building in Nonlinear Mixed Effects Models

   Författare :Jakob Ribbing; E. Niclas Johnsson; Mats O. Karlsson; Janet Wade; Uppsala universitet; []
   Nyckelord :Pharmacokinetics Pharmacotherapy; Pharmacokinetics; Pharmacodynamics; Modeling; Covariate selection; Stepwise selection; Covariate analysis; Methodology; Model validation; Model evaluation; Type-2 diabetes; Beta-cell function; Meta analysis; Cross-validation; Least absolute shrinkage and selection operator; Pharmacometrics; ED optimization; Farmakokinetik Farmakoterapi;

   Sammanfattning : Population pharmacokinetic-pharmacodynamic (PK-PD) models can be fitted using nonlinear mixed effects modelling (NONMEM). This is an efficient way of learning about drugs and diseases from data collected in clinical trials. LÄS MER

7. 15. Wnt signalling in the development of ventral midbrain dopaminergic neurons

   Författare :Gonçalo de Sá e Sousa de Castelo-Branco; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Dopaminergic Neuron; Ventral Midbrain Development; Writs; Dickkopf; beta-catenin; GSK-3beta; Stem Cells; Neural Precursors;

   Sammanfattning : Dopaminergic (DA) neurons in the ventral midbrain (VM) are one of the major cell types lost in Parkinson's disease (PD). Proof-of-principle exists for cell replacement therapies for PD, but wider application is halted by the unavailability of abundant sources of DA neurons. Stem cells might constitute one of these sources. LÄS MER
