Red meat and colon cancer : should we become vegetarians, or can we make meat safer ? [PDF]

open access: yes, 2011
The effect of meat consumption on cancer risk is a controversial issue. However, recent meta-analyses show that high consumers of cured meats and red meat are at increased risk of colorectal cancer.

Interaction of antimalarial drugs with hemin

open access: yesBioscience Reports, 1983
Hemin (ferriprotoporphyrin IX) is shown to form complexes with the chloroquine class of antimalarial drugs. The Soret band of hemin becomes optically active upon the addition of chiral drugs. Results on the hemin-induced quenching of the fluorescence of chloroquine are consistent with the formation of a 2:1 hemin:drug complex with a formation constant ...

Influence of Cosolvents on the Pressure Stability of Human Serum Albumin

open access: yesphysica status solidi (a), EarlyView.
Human serum albumin is able to bind various hydrophobic substances and drugs. To investigate this interaction, the protein structure is analyzed using small‐angle X‐ray scattering under high hydrostatic pressure. The resulting radius of gyration (see picture) indicates that hydrophobic substances influence the pressure stability of HSA differently ...

Nucleic Acid‐Modified Nanoparticles for Cancer Therapeutic Applications

open access: yesSmall, EarlyView.
Nucleic acid‐modified nanoparticles act as functional hybrids for chemodynamic, photodynamic, photothermal, and gene therapy of cancer cells. These are exemplified with aptamer‐modified catalytic nanoparticles, photosensitizer‐oligonucleotide functionalized nanoparticles, drug‐loaded stimuli‐responsive nucleic acid‐caged nanoparticle carriers, and ...
