The histidine-containing protein (HPr) is the energy coupling protein of the phosphoenolpyruvate-dependent carbohydrate:phosphotransferase system (PTS), which catalyzes the transport of carbohydrates in bacteria. In Bacillus subtilis and close relatives, global regulation of carbon catabolite control occurs on the binding of the complex of CcpA (catabolite control protein A) and P-Ser-HPr (sery...

Regular exercise is a good strategy for treating many metabolic disorders, including type 2 diabetes and obesity. Some part of the beneficial effects of exercises are due to endocrine exercise, including fatty tissue which plays an important role in regulating energy metabolism, body composition, and insulin resistance [1]. The adipose tissue, as an active endocrine and paracrine tissue as well...

K inetoplastid protozoa include the parasites Trypanosoma brucei, Trypanosoma cruzi, and various species of Leishmania that are responsible for African trypanosomiasis, Chagas’ disease, and leishmaniasis, devastating diseases that aff lict millions of victims largely in the tropical regions of the globe. In addition to eliciting long-standing interest from medical microbiologists, these intrigu...

Sacrificial dilemmas, especially trolley problems, have rapidly become the most recognizable scientific exemplars of moral situations; they are now a familiar part of the psychological literature and are featured prominently in textbooks and the popular press. We are concerned that studies of sacrif icial dilemmas may lack experimental, mundane, and psychological realism and therefore suffer fr...

There is now widespread recognition that relationships have important implications for health. To better understand this linkage, scholars have called for greater bridging between relationship science and the study of health. The goal of this paper is to raise awareness of another factor that needs to be incorporated into this area of study: culture. I recommend three steps that researchers can...

There has been an increasing interest in the applications of polarimetric microwave ractiotneters for ocean wind remote sensing. Aircraft and spaceborlle radiometers have found a few Kelvins wind direction signals in sea surface brightness temperatures, in addition to their sensitivities on wind speeds. However, it was not clear what physical scattering rnechanistus produced the observed bright...

The literature on participatory practices in organizations has been less coherent and more limited to subspecialties than the literature on bureaucracy in organizations–despite a number of celebrated studies of participation in 20th century American sociology. Due to the practical nature of participatory reforms and the ambiguity of participation as a concept, attempts to review participatory k...
