Hematopoietic progenitor kinase-1 (HPK1), which is expressed predominantly in hematopoietic cells, was identified as a mammalian Ste20 homologue that, upon transfection, leads to activation of JNK/SAPK in nonhematopoietic cells. The JNK/SAPK pathway is activated by various environmental stresses and proinflammatory and hematopoietic cytokines. Upstream activators of HPK1 currently remain elusiv...

With the thickness of only a single atomic layer, graphene displays many interesting surface properties. A general observation is that wrinkles are formed on graphene oxide (GO) when it is dried in the presence of adsorbed inorganic nanoparticles. In this case, evaporation induced wrinkling is not an elastic deformation but is permanent. Understanding the nanoscale force of wrinkle formation is...

Dehydrins are a family of proteins (LEA [late-embryogenesis abundant] D11) commonly induced by environmental stresses associated with low temperature or dehydration and during seed maturation drying. Our previous genetic studies suggested an association of an approximately 35-kD protein (by immunological evidence a dehydrin) with chilling tolerance during emergence of seedlings of cowpea (Vigna...

Hard turning offers improved manufacturing efficiency but requires great control of the cutting process to achieve required machining-induced surface integrity with respect residual stresses, topography, and near-surface microstructure. This research work is focused on studying effect speed, feed rate, depth cut, chamfer angle, coolant pressure after hard martensitic AISI 52100 steel. The resul...

ured. Morphological changes were analyzed by both multivariate and geometric morphometric methods. Results obtained by the two methods were in concordance. Shape analysis allows us to discriminate predator-induced, competitor-induced and drying-induced morphotypes. Life-history traits under isolated environmental factors were also consistent with precedent studies. In complex environments we ob...

To establish the most convenient and effective method to dry tangerine peels, different methods (sun drying, hot-air drying, freeze drying, vacuum drying, and medium- and short-wave infrared drying) were exploited. Our results indicated that medium- and short-wave infrared drying was the best method to preserve nutraceutical components; for example, vitamin C was raised to 6.77 mg/g (D.W.) from...

To explore the collapse of eucalyptus wood cells during the drying process, continuous and intermittent drying were carried out on Eucalyptus urophylla. The shrinkage throughout the intermittent drying process was less than that of continuous drying. According to observations of cells made using scanning electron microscopy (SEM), there was a large difference in the degree of cell collapse betw...
