Vitamin D is a seco-steroid hormone with multiple functions in the nervous system. Physiological brain mechanisms of vitamin D and its receptors include neuroprotection, antiepileptic effects, immunomodulation, possible interplay with several brain neurotransmitter systems and hormones, as well as the regulation of behaviours. Here we review the important role of the vitamin D neuroendocrine sy...

A steady momentum of innovations and breakthroughs has convincingly pushed the limits unsupervised image representation learning. Compared to static 2D images, video one more dimension (time). The inherent supervision existing in such sequential structure offers a fertile ground for building learning models. In this paper, we compose trilogy exploring basic generic sequence from spatial, spatio...

Plants have evolved multiple mechanisms to selectively suppress pathogens by production of secondary metabolites with antimicrobial activities. Therefore, direct selections for antiviral compounds from plants can be used to identify new agents with potent antiviral activity but not toxic to hosts. Here, we provide evidence that a class of compounds, seco-pregnane steroid glaucogenin C and its m...

This study is an investigation into the roles of wildfire and changing agricultural practices in controlling the inter-decadal scale trends of suspended sediment production from semi-arid mountainous rivers. In the test case, a decreasing trend in suspended sediment concentrations was found in the lower Salinas River, California between 1967 and 2011. Event to decadal scale patterns in sediment...
