Published: March 2010

An array sensor comprising six off-the-shelf indicators doped in a poly(ether-urethane) recognizes five cations, seven anions and thirty-five ion pairs at pH 5-9 in water. Such a discrimination capacity and recognition efficiency (6 : 35) with > or = 93% accuracy is rare. Low cost and wide availability of various polymers and indicators could make this approach useful in numerous applications.

Background: Reversible post-translational modifications, phosphorylation and dephosphorylation, on tau protein play a critical role in the microtubule (MT) modulation. However, abnormal tau phosphorylation, which occurs in tauopathies such as Alzheimer's disease (AD), causes the dissociation of tau from MTs. The dissociated tau then aggregates into sequent forms from soluble oligomers to paired helical filaments (PHF), and insoluble neurofibrillary tangles (NFTs), a hallmark of AD.

Background: The microtubule-associated Tau gene (MAPT) undergoes alternative splicing to produce isoforms with varying combinations of microtubule-binding region (MTBR) repeats (3R, 4R). The MTBR is the predominant region that forms paired helical filaments and neurofibrillary tangles fibrils in disease. Alzheimer's disease (AD) is a mixed Tauopathy containing both 3R and 4R isoforms.

Photodynamic immunotherapy (PIT) has emerged as a promising approach for efficient eradication of primary tumors and inhibition of tumor metastasis. However, most of photosensitizers (PSs) for PIT exhibit notable oxygen dependence. Herein, a concept emphasizing on transition from molecular PSs into semiconductor-like photocatalysts is proposed, which converts the PSs from type II photoreaction to efficient type I photoreaction.

Unified description of thermal and nonthermal laser-induced ultrafast structural changes in materials.

The ultrafast ionic dynamics in solids induced by intense femtosecond laser excitation are controlled by two fundamentally different yet interrelated phenomena. First, the substantial generation of hot electron-hole pairs by the laser pulse modifies the interatomic bonding strength and characteristics, inducing nonthermal ionic motion. Second, incoherent electron-ion collisions facilitate thermal equilibration between electrons and ions, achieving a uniform temperature on a picosecond timescale.
