Abstract Background Major depressive disorder (MDD) is a common but severe psychiatric illness characterized by mood and diminished interest. Both nucleotide-binding oligomerization domain, leucine-rich repeat pyrin domain-containing 1 (NLRP1) inflammasome autophagy have been reported to implicate in the pathological processes of depression. However, mechanistic interplay between NLRP1 inflammasome, autophagy, depression still poorly known. Methods Animal model was established chronic social...
Abstract Adiabatic waveguide taper and on-chip wavelength demultiplexer are the key components of photonic integrated circuits. However, these two kinds devices which were designed by traditional semi-analytic methods or brute-force search usually have large size.
