North-Central China is a region in which the air temperature has clearly increased for several decades. Picea meyeri and Larix principis-rupprechtii are the most dominant co-occurring tree species within the cold coniferous forest belt ranging vertically from 1800 m to 2800 m a.s.l. in this region.

Abstract Background Saussurea involucrata survives in extreme arctic conditions and is very cold-resistant. This species grows rocky, mountainous areas with elevations of 2400–4100 m, which are snow-covered year-round subject to freezing temperatures. S. ’s ability survive an low-temperature environment suggests that it has particularly high photosynthetic efficiency, providing a magnificent mo...

The responses of specific cold-sensitive afferents and cold-sensitive mechanoreceptors were recorded from rat pudendal nerve. A local infiltration of ouabain into the region of the afferent terminals caused a dramatic increase in discharge at warm temperatures without significant effect on discharge in the cold. These results suggest that an electrogenic sodium pump is the generator potential m...

BACKGROUND Herpes simplex virus type 1 (HSV-1) infects >70% of the United States population. We identified a 3-megabase region on human chromosome 21 containing 6 candidate genes associated with herpes simplex labialis (HSL, "cold sores"). METHODS We conducted single nucleotide polymorphism (SNP) scans of the chromosome 21 region to define which of 6 possible candidate genes were associated w...
