Wood production is dependent on the activity of the vascular cambium, which develops from the fascicular and interfascicular cambia. However, little is known about the mechanisms controlling how the vascular cambium is developed in woody species. Here, we show that PtrHB4, belonging to the Populus HD-ZIP III family, plays a critical role in the process of vascular cambium development. PtrHB4 wa...

In this paper, using generalized partial skew versions of Armendariz rings, we study the transfer of left (right) zip property between a ring R and partial skew generalized power series rings

MOTIVATION After 10-year investigations, the folding mechanisms of beta-hairpins are still under debate. Experiments strongly support zip-out pathway, while most simulations prefer the hydrophobic collapse model (including middle-out and zip-in pathways). In this article, we show that all pathways can occur during the folding of beta-hairpins but with different probabilities. The zip-out pathwa...

In this paper a system for the segmentation of unconstrained handwritten ZIP codes is presented. A binarization algorithm is described that utilizes the bimodal nature of the input 256 gray level histogram. ZIP code images are scaled to a standard size for further processing. Objects that are not comparable to the size of numerals are classified as noise and removed. An algorithm that segments ...

The virtually fatless A-ZIP/F-1 mouse is profoundly insulin resistant, diabetic, and a good model for humans with severe generalized lipoatrophy. Like a number of other mouse models of diabetes, the A-ZIP/F-1 mouse has elevated serum corticosterone levels. Leptin infusion lowers the corticosterone levels, suggesting that leptin deficiency contributes to the hypercorticosteronemic state. To test...

Class III homeodomain leucine zipper (HD-ZIP III) transcription factors regulate critical developmental programs in plants; these include leaf polarity, polarity along the shoot-root axis, and stem cell specification and proliferation. One of the defining features of HD-ZIP III proteins is the presence of a Per-ARNT-Sim-like (PAS-like) MEKHLA domain at the C terminus. PAS-like domains are known...

There is limited data regarding health disparities for access to health care. The majority of prior studies have focused on the primary care workforce and underserved patient populations with respect to lower socio-economic status, race and insurance status. Few studies assess these issues in dermatology. At the state level, increased numbers of both family physicians and specialists per capita...

We have investigated the effect of protein kinase Mzeta (PKMζ) inhibition in the basolateral amygdala (BLA) upon the retention of a nonspatial learned active avoidance response and conditioned taste-aversion (CTA) acquisition in rats. ZIP (10 nmol/μL) injected into the BLA 24 h after training impaired retention of a learned avoidance-jumping response assessed 7 d later when compared with contro...
