Air quality is concerned with pollutants in both the gas phase and solid or liquid phases. The latter are referred to as aerosols, which are multifaceted agents affecting air quality, weather and climate through many mechanisms. Unlike gas pollutants, aerosols interact strongly with meteorological variables with the strongest interactions taking place in the planetary boundary layer(PBL). The PBL hosting the bulk of aerosols in the lower atmosphere is affected by aerosol radiative effects. Both aerosol scattering and absorption reduce the amount of solar radiation reaching the ground and thus reduce the sensible heat fluxes that drive the diurnal evolution of the PBL. Moreover, aerosols can increase atmospheric stability by inducing a temperature inversion as a result of both scattering and absorption of solar radiation, which suppresses dispersion of pollutants and leads to further increases in aerosol concentration in the lower *** positive feedback is especially strong during severe pollution events. Knowledge of the PBL is thus crucial for understanding the interactions between air pollution and meteorology. A key question is how the diurnal evolution of the PBL interacts with aerosols, especially in vertical directions, and affects air *** review the major advances in aerosol measurements, PBL processes and their interactions with each other through complex feedback mechanisms, and highlight the priorities for future studies.

The aerosol effect on clouds was explored using remote sensing of aerosol and cloud data at Shouxian, China. Non-precipitation, ice-free, and overcast clouds were firstly chosen by a combination of sky im- ages from the Total Sky Imager （TSI）, cloud base heights from the Ceilometer, and vertical temperature profiles from the Balloon-Borne Sounding System （BBSS）. Six cases were chosen in summer, and seven in autumn. The averaged cloud effective radii （re）, cloud optical depth （COD）, aerosol total light scattering coefficient （a）, and liquid water path （LWP） are, respectivey, 6.47 μm, 35.4, 595.9 mm-1, 0.19 mm in summer, and 6.07 μm, 96.0, 471.7 mm-1, 0.37 mm in autumn. The correlation coefficient between re and tc was found to change from negative to positive value as LWP increases.

Oligodendrocytes, the myelinating glial cells of the nervous system, in various disease states display great vulnerability to excitotoxic damage, oxidative stress, and inflammatory cytokines. Besides demyelinating diseases where oligoden-drocyte injury is primarily implicated, damage to them also occurs secondarily in various neuropathies. Oligoprotec-tion should, therefore, be looked into something not just as a means for protecting oligodendrocytes alone but also as a common target of protecting neurons and the neurogliovascular unit as a whole. In this review, we provide a descrip-tion on oligodendrocytes, the reasons for their vulnerability, the evolving new concepts of protecting neurovascular unit and recently neurogliovascular unit;the various diseases where oligodendrocyte injury is implicated with a brief idea on different injury mechanisms of oligodendrocytes. Finally, we present the summary of the drugs that have shown promising results in protecting oligodendrocytes or in protecting white matter as a whole in different in-vivo and in-vitro models.
