A novel hemicyanine-based fluorescent probe was developed for the fast, selective, and reversible detection of Cu2+ ions with "turn-on" fluorescence response in the aqueous solution. The sensing mode was demonstrated through fluorescence, UV-vis, HRMS, 1H NMR, and DFT calculations. The probe was successfully used for the imaging of Cu2+ ions in living cells.The establishment of an objective and effective approach is imperative for depression diagnosis and anti-depressant efficacy evaluation, which might eliminate the drawbacks of current clinical diagnoses that rest on subjective scales. Oxidative stress may lead to depression with an excess of oxidants, but correspondingly, reductants play essential roles in retaining redox homeostasis, one of which is mitochondrial cysteine (Cys). Therefore, real-time and in situ monitoring of mitochondrial Cys fluctuations in the mouse brain is expected to achieve effective diagnosis and pharmacodynamic evaluation of depression. Herein, we developed a near-infrared fluorescence imaging probe (CSS) for the detection of mitochondrial Cys in the mouse brain. CSS is responsive to changes in the level of Cys at 705 nm and has high sensitivity, selectivity, temporal-spatial resolution and deep tissue penetration. selleck inhibitor Utilizing the probe, we revealed that the concentration of mitochondrial Cys decreased in the brains of mice with depression. Importantly, in the brains of depressed mice with three antidepressants, varying levels of Cys were observed, indicating different antidepressant efficacies. Altogether, this work affords a convincing strategy for the precise diagnosis of depression and pharmacodynamic evaluation of antidepressants.β-Lactoglobulin amyloid fibril (BLGF)-capped gold nanoclusters (Au NCs) with red, green and blue emissions were fabricated via pH-dependent reduction strategy. The BLGF-Au NCs exhibited 3.2 times enhancement of fluorescence (λex = 500 nm, λem = 684 nm), a significant 42 nm red shift, a 11.57% quantum yield and a 1.4 μs decay time compared with native β-lactoglobulin (BLG)-stabilized Au NCs. Meanwhile, the multicolor Au NCs were employed for cell imaging via incubation with A549 cells for 14 h. According to the Michaelis-Menten equation, the kinetic parameters of the BLGF-Au NCs showed a lower Km value (66 μmol L-1) for 3,3,5,5-tetramethylbenzidine (TMB) and a higher vmax (3.74 × 10-8 M s-1) for H2O2, which are comparable with other artificial nanoenzymes and natural peroxidases. Based on the highly intrinsic peroxidase-like activity of the BLGF-Au NCs, a colorimetric method was developed for glucose determination with a detection limit of 1.5 μmol L-1 by determining the variation of the absorption at 652 nm, ranging from 5 to 100 μmol L-1. In addition, the glucose assay method also revealed a 101.02 to 104.16% recovery in a real human serum sample.Mass spectrometry imaging (MSI) is a powerful analytical technique that enables detection, discovery, and identification of multiple classes of biomolecules, while simultaneously mapping their spatial distributions within a sample (e.g., a section of biological tissue). The limitation in molecular coverage afforded by any single MSI platform has led to the development of multimodal approaches that incorporate two or more techniques to obtain greater chemical information. Matrix-assisted laser desorption ionization (MALDI) is a preeminent ionization technique for MSI applications because the wide range of available matrices allows some degree of enhancement with respect to the detection of particular molecular classes. Nonetheless, MALDI has a limited ability to detect and image several classes of molecules, e.g., neutral lipids, in complex samples. Laser desorption ionization from silicon nanopost arrays (NAPA-LDI or NAPA) has been shown to offer complementary coverage with respect to MALDI by providing improved detection of neutral lipids and some small metabolites. Here, we present a multimodal imaging method in which a single tissue section is consecutively imaged at low and high laser fluences, generating spectra that are characteristic of MALDI and NAPA ionization, respectively. The method is demonstrated to map the distributions of species amenable to detection by MALDI (e.g., phospholipids and intermediate-mass metabolites) and NAPA (e.g., neutral lipids such as triglycerides and hexosylceramides, and small metabolites) in mouse brain and lung tissue sections.Many medications prescribed in the Netherlands have adverse effects on the oral mucosa. Adverse events often described are stomatitis, white lesions, abnormal pigmentation and sensibility disorders. Stomatitis is frequently observed in patients using medications for the treatment of malignancies or auto-immune diseases. Important causative classes of medicines are alkylating agents, anthracyclines, monoclonal antibodies, protein kinase inhibitors, purine derivatives, pyrimidine antagonists, taxanes and vinca alkaloids. White oral lesions often concern candidiasis and are frequently seen in patients using certain immunosuppressants and antibiotics. Abnormal pigmentation is frequently seen in patients using hydroxycarbamide, an antineoplastic agent. Sensibility disorders of the oral mucosa are described in several classes of medications, including protein kinase inhibitors. It is very important oral healthcare professionals can recognise possible adverse effects of medications on the oral mucosa. When it is probable an anomaly of the oral mucosa is caused by medication, the oral healthcare professional should contact the prescribing physician to discuss the possibility of adjusting or discontinuing the medication.The International Caries Consensus Collaboration (ICCC) presented recommendations on terminology, methods of carious tissue removal and managing cavitated carious lesions. It identified 'dental caries' as the disease that dentists should manage by controlling the activity of existing cavitated lesions by preserving as much hard tissue as possible, maintaining pulp sensibility and retaining functional teeth in the long-term. The ICCC recommended the level of hardness as the criterion for determining the clinical consequences of the process of demineralisation and defined new strategies for the selective removal of carious tissue. The starting point is to effectively remove the biofilm from cavitated carious lesions. Only when cavitated carious lesions are either non-cleansable or can no longer be sealed, are restorative interventions indicated, with due regard for the principles of a minimally invasive approach. Applying a restoration facilitates biofilm removal, guards the pulpodental complex and restores form, function and aesthetics.
