Adenine Phosphoribosyltransferase Deficiency [PDF]

Clinical Journal of the American Society of Nephrology, 2012
Summary Complete adenine phosphoribosyltransferase (APRT) deficiency is a rare inherited metabolic disorder that leads to the formation and hyperexcretion of 2,8-dihydroxyadenine (DHA) into urine. The low solubility of DHA results in precipitation of this compound and the formation of urinary crystals and stones.

Self‐Cascade Catalytic Reaction–Assisted Apoptosis/Calcicoptosis/Ferroptosis Induction with Microsphere‐Aggregated Hydrogels in Triple‐Negative Breast Cancer Therapy

Advanced Functional Materials, EarlyView.
Hyaluronic acid‐dopamine‐based intra‐crosslinked microsphere including cisplatin (HPC MS) is fabricated by spray‐drying and calcium/iron ions are introduced for interparticle crosslinking. Designed microsphere‐aggregated hydrogel (MAH) system including cisplatin/CaO2/FeSO4 can provide apoptosis/calcicoptosis/ferroptosis‐mediated chemo/cascade ...

Hydro-chemical study of the evolution of interstellar pre-biotic molecules during the collapse of molecular clouds

, 2012
One of the stumbling blocks for studying the evolution of interstellar molecules is the lack of adequate knowledge of the rate co-efficients of various reactions which take place in the Interstellar medium and molecular clouds.

Uptake of purines in Plasmodium falciparum-infected human erythrocytes is mostly mediated by the human Equilibrative Nucleoside Transporter and the human Facilitative Nucleobase Transporter [PDF]

, 2010
<b>Background</b>: Plasmodium parasites are unable to synthesize purines de novo and have to salvage them from the host. Due to this limitation in the parasite, purine transporters have been an area of focus in the search for anti-malarial ...

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment

Advanced Functional Materials, EarlyView.
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

Temperature dependence of Raman vibrational bandwidths in poly(rA) and rAMP [PDF]

, 1993
Isotropic and anisotropic spontaneous Raman spectra were obtained from solutions of poly(ra) and rAMP in buffer. The temperature dependence of these spectra was measured to elucidate the influence of macromolecular dynamics and solvent dynamics on the ...

Polarographic Behaviour of Adenine [PDF]

Nature, 1946
WORK in this laboratory on differences in mechanism between normal and malignant cells has shown the great need for improved methods of analysis and characterization of nucleic acids. Investigations which I began before the War indicated to me the value of the polarograph as an analytical tool in the study of inorganic cell constituents, and there was ...
