Dysfunctional TRIM31 of POMC Neurons Provokes Hypothalamic Injury and Peripheral Metabolic Disorder under Long‐Term Fine Particulate Matter Exposure

open access: yesAdvanced Science, EarlyView.
Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...

Calibration of a fisher air-permeability apparatus for determining specific surface

open access: closedThe Analyst, 1966
Calibrating the Fisher sub-sieve sizer at a single particle-size level does not ensure accuracy at other levels unless several variables are controlled. Instrument modification that give better control of the several variables, and a calibration method that ensures accurate air-flow measurement without depending on a particle-size standard, are ...

The specific surface of powders. A modification of the theory of the air‐permeability method

open access: closedJournal of the Society of Chemical Industry, 1947
AbstractThe paper describes a modification of the Kozeny theory of the air‐permeability method for determining the specific surface of powders to take into account the effect of “slip” at the walls of the pores in the bed of powder. The dependence of the measured value of specific surface on the mean pressure in the bed has been examined experimentally,
