Modular organizations of the global brain functional network in major depressive disorder (MDD) group (A) with 5 modules, and in healthy control group (B) with 4 modules. (A) Brain modular organization of MDD patients. Module I: default model network/cognition control; Module II: executive and strategic processing. Module III: sensory-motor/auditory and verbal functions; Module IV: visual and verbal functions; Module V: mnemonic and affective processing. (B) Brain modular organization of healthy controls. Module I: default model network/cognition control, and executive and strategic regions; Module II: sensory-motor/visual processing; Module III: auditory-verbal operation. Module IV: mnemonic and affective processing. The colors in each module denote different brain regions.

The form of buoyancy control module (BCM) in operation: (a) shape change; (b) original state; (c) 110% of original size; (d) 120% of original size; (e) 130% of original size.

(A) Schematics and (B) a prototype of the fluorescent microfluidic flow cytometry enabling the measurement of copy numbers of specific intracellular proteins at the single-cell level. The developed instrument had five key components: A microfluidic module, a fluorescent module, a pressure module, a LabVIEW platform for instrument operation, and a MATLAB platform for data processing. (C) Working flow chart of the developed microfluidic instrument. Under the control of the LabVIEW platform for instrument operation, the pressure module flushed cells stained with fluorescence-labelled antibodies through the constriction channel of the microfluidic module while fluorescent intensities were quantified by the fluorescent module and then were further translated to the copy number of specific intracellular proteins at the single-cell level, leveraging the MATLAB platform for data processing.
