Altered chromatin architecture underlies progressive impairment of the heat shock response in mouse models of Huntington disease

Huntington disease (HD) is a devastating neurodegenerative disorder for which there are no disease-modifying treatments. Previous studies have proposed that activation of the heat shock response (HSR) via the transcription factor heat shock factor 1 (HSF1) ...

Improving Protein Pharmacokinetics by Engineering Erythrocyte Affinity

Stephane Kontos, Jeffrey Alan Hubbell

Poor pharmacokinetic profiles are often the underlying reason for the failure of novel protein drugs to reach clinical translation. Current passive half-life improvement methods focus on increasing the apparent hydrodynamic radius of the drug. We sought to ...

P450-mediated electrochemical sensing of drugs in human plasma for personalized therapy

Giovanni De Micheli, Sandro Carrara, Andrea Cavallini

Nowadays, the concept of personalized therapy gains momentum. Pharmacogenomics, which represents a first answer to these needs, has the drawback of neglecting some variations of therapy response due to non-genetic factors. The aim of this paper is to inves ...

Trace Metal Speciation and Bioavailability in Surface Waters of the Black Sea Coastal Area Evaluated by HF-PLM and DGT

Trace metal speciation in seawater from the Bulgarian Black Sea coast was studied in situ by hollow fiber permeation liquid membrane (HF-PLM) and by diffusion gradients in thin-film gels (DGT). The concentrations of Cd, Cu, Ni, and Pb determined by HF-PLM ...

Peptide ligands for targeting and retention of nanoparticles and protein therapeutics in articular cartilage

Dominique André Rothenfluh

Osteoarthritis (OA) is one of the most common causes of pain and disability. Currently, non-surgical treatment is limited to analgesic and anti-inflammatory drugs, which are not capable of either modifying the disease process or regenerate damaged parts in ...

In-situ determination of trace metal species in surface waters of Black Sea coastal area: comparison to bioavailability by green microalgae

Trace metal speciation in seawater from the Bulgarian Black Sea coast was studied in situ by hollow fiber permeation liquid membrane (HF-PLM) and by diffusion gradients in thin- film gels (DGT). The concentrations of Cd, Cu, Ni, and Pb determined by HF- ...

Cyclosporin analogues

Arnaud Hamel

Cyclosporins are a family of hydrophobic cyclic undecapeptides produced by the fungus Tolypocladium niveum. The main metabolite cyclosporin A (CsA, see Scheme, R = R' = H) is the first line drug currently used to prevent rejection of organ transplants. Its ...

CYP3A activity measured by the midazolam test is not related to 3435 C >T polymorphism in the multiple drug resistance transporter gene

Jacques Fellay, Amalio Telenti, Thierry Buclin

A recent study with 69 Japanese liver transplants treated with tacrolimus found that the MDR13435 C >T polymorphism, but not the MDR12677 G >T polymorphism, was associated with differences in the intestinal expression level of CYP3A4 mRNA. In the present s ...

Population pharmacokinetics and effects of efavirenz in patients with human immunodeficiency virus infection

Jacques Fellay, Amalio Telenti, Thierry Buclin

The reverse transcriptase inhibitor efavirenz is currently used at a fixed dose of 600 mg/d. However, dosage individualization based on plasma concentration monitoring might be indicated. This study aimed to assess the efavirenz pharmacokinetic profile and ...

Responses of Mycobacterium sp LB501T to the low bioavailability of solid anthracene

Several recent reports have indicated that some bacteria may have adapted to the low bioavailability of hydrophobic environmental chemicals and that generalizations about the bioavailability of compounds such as polycyclic aromatic hydrocarbons (PAHs) may ...
