Mn-based nanoparticles have been regarded as a new class of probes for magnetic resonance imaging (MRI), but their low relaxivity is the major obstacle for applications in vivo. Herein, we designed and constructed a multifunctional nanotheranostic (FA-Mn3O4@PDA@PEG) for MRI guided combinatorial chemo-/photothermal therapy (PTT) for cancer. The ultrahigh relaxivity of 14.47 mM-1 s-1 makes the na...

Generalized retinal arteriolar narrowing is an important sign of systemic hypertension, and a lower arteriolar:venular diameter ratio predicts the risk of hypertension. We investigated whether this association was based on arteriolar or venular diameters or both. This study was based on the prospective population-based Rotterdam Study (1990-1993) and included 1900 participants (> or =55 years o...
BACKGROUND Little is known about the nature of metastasis to small cervical lymph nodes (SCLNs) in the patients with nasopharyngeal carcinoma (NPC) examined by using 18-fluoro-2-deoxy-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT). The present study aimed to evaluate the diagnostic values of PET/CT in identifying metastasis in SCLNs in NPC patients. METHODS Magnet...
SCFAs (short-chain fatty acids), fermentation products of bacteria, influence epithelial-specific gene expression. We hypothesize that SCFAs affect goblet-cell-specific mucin MUC2 expression and thereby alter epithelial protection. In the present study, our aim was to investigate the mechanisms that regulate butyrate-mediated effects on MUC2 synthesis. Human goblet cell-like LS174T cells were t...
Core–shell Au NPs@MOF-808 architecture has been synthesized using sustainable conditions. NPs capping agent removal optimized to boost the catalytic efficiency of composite material.
Dy3+-doped CaF2-SrF2 crystals with various Dy3+ dopant concentrations were synthesized by multicrucible temperature gradient technology (MC-TGT). Dy:CaF2-SrF2 fluorite structured and crystallized in cubic Fm3¯m space group, as characterized X-ray diffraction. The crystallographic site concentration was calculated from the measured density Archimedes’ hydrostatic weighing principle. optical tran...
The oxy-myoglobin (Mb-O2) structure was probed by QM/MM (hybrid quantum mechanical/ molecular mechanical) calculations using DFT/MM to elucidate the effect of the heme propionates and the protein matrix on the chemistry of heme Fe-O2 moiety. On this line, we have probed the role of His97 in various protonation states of the heme propionate-6.
