Flavor characteristics of raw shrimp,high-salt and low-salt shrimp paste were evaluated and compared by sensory analysis,headspace-gas chromatography-ion mobility spectrometry(HS-GC-IMS)and solid-phase microextraction-gas chromatography-mass spectrometry(SPME-GC-MS).In addition,aroma profiles and aroma-active compounds in these three samples were analyzed by solvent-assisted flavor evaporation-gas chromatography-olfactometry-mass spectrometry(SAFE-GC-O-MS).Results of sensory evaluation revealed that these three samples showed significant differences in sensitivity to the W2W,W2S,W1S and W1W sensors of the electronic nose(p<0.05),which represent organic sulfides,alkane aromatic compounds,short chain alkanes,and sulfides,*** of sensory parameters indicated tha high-salt shrimp paste had a strong roasted and meaty aroma,while low-salt shrimp paste showed an umami aroma more similar to raw shrimp.A total of 118 volatile compounds were identified using the three afore-mentioned gas chromatography *** them,37 aroma-active compounds were detected by ***-salt shrimp was shown to contain more acids,aldehydes and heterocyclic compounds,which resembled cheese,roasted and meaty *** contrast,low-salt shrimp paste contained more esters,which was similar to the umami aroma profile of raw ***,pyrazines were only produced in fermented shrimp paste samples,suggesting that they were produced during the fermentation process and they may contribute unique roasted and meaty aromas,which were important for the overall aroma characteristics of shrimp paste.

Summary of main observation and conclusion: Here we report the design and fabrication of high‐performance pressure sensors based on three‐ dimensional (3D) graphene foam filled polydimethylsiloxane (GF@PDMS) composite with a broad sensing range spaning from 0.05 kPa to 130 kPa. The interpretation of device functioning mechanism can be classified into low and high pressure sensing regions. In the low pressure region (sensors exhibited accuracy, sensibility and reproducibility to detect pressure signals with remarkable stability for over 16000 loading‐unloading cycles, indicating its great potential for practical applications. Moreover, the GF@PDMS sensors also showed high performances in the detection of dynamic pressures, such as subtle mechanical vibration signals, as well as physiology vibrational signals generated by human throats. We expect this technology could be integrated into different sensing systems for the applications in wearable smart electronics and human‐machine communications. [ABSTRACT FROM AUTHOR]

Accelerating the clearance of intracellular protein aggregates represents a viable approach for the treatment of neurodegenerative *** have previously demonstrated enhanced degradation of mutant huntingtin protein aggregates through MEK/ERK1/2 signaling pathway regulated autophagy induced by europium hydroxide nanorods or graphene oxide nanoparticles. Recently,we have synthesized biocompatible MnFeO nanoparticles(NPs) and demonstrated their unique effect in accelerating the clearance of mutant huntingtin. In contrast,UPS,rather than autophagy,was responsible for the efficient mutant huntingtin degradation facilitated by MnFeO ***,we demonstrated that MnFeO NPs enhanced K48-linked ubiquitination of GFP-Htt(Q74).Moreover,ubiqinlin-1,but not p62/SQSTM1,served as the ubiquitin receptor that mediated the enhanced degradation of mutant huntingtin by MnFeO NPs. Our findings may have implications for developing novel nanomedicine for the therapy of HD and other polyglutamine expansion diseases.
