Although evidence indicates that the abnormal accumulation of α-synuclein (α-syn) in dopamine neurons of the substantia nigra is the main pathological feature of Parkinson's disease (PD), no compounds that have both α-syn anti-aggregation and α-syn degradation functions have been successful in treating the disease in the clinic. Here, we show that black phosphorus nanosheets (BPNSs) interact directly with α-syn fibrils to trigger their disaggregation for PD treatment. Moreover, BPNSs have a specific affinity for α-syn through van der Waals forces...

Secretory carcinoma is a malignant salivary gland tumor, which typically presents as an indolent painless mass within the parotid gland. Involvement of minor gland is reported but less common. Secretory carcinoma was often misclassified as other salivary gland mimics and in particular, acinic cell carcinoma prior to 2010. It was first recognized by Skalova et al. as a molecularly distinct salivary gland tumor harboring the same fusion gene as well as histological and cytogenetic features seen in juvenile breast cancer...

Dental pulp is the only soft tissue in the tooth which plays a crucial role in maintaining intrinsic multi-functional behaviors of the dentin-pulp complex. Nevertheless, the restoration of fully functional pulps after pulpitis or pulp necrosis, termed endodontic regeneration, remained a major challenge for decades. Therefore, a bioactive and in-situ injectable biomaterial is highly desired for tissue-engineered pulp regeneration. Herein, a decellularized matrix hydrogel derived from porcine dental pulps (pDDPM-G) was prepared and characterized through systematic comparison against the porcine decellularized nerve matrix hydrogel (pDNM-G)...

Seawater batteries that directly utilize natural seawater as electrolytes are ideal sustainable aqueous devices with high safety, exceedingly low cost, and environmental friendliness. However, the present seawater batteries are either primary batteries or rechargeable half-seawater/half-nonaqueous batteries because of the lack of suitable anode working in seawater. Here, we demonstrate a unique lattice engineering to unlock the electrochemically inert anatase TiO2 anode to be highly active for the reversible uptake of multiple cations (Na+ , Mg2+ , and Ca2+ ) in aqueous electrolytes...
