• Integration of forms. I review the basics about integrating an n-form over an n-dimensional manifold. Let M be a smooth n-manifold. We need M to be orientable. There are several equivalent characterizations of orientability; for example, M is orientable if there exists a nowhere vanishing continuous n-form ω. Given such an n-form we can select from a smooth atlas of M a subatlas for which the...

In bacterial chemotaxis, an assembly of transmembrane receptors, the CheA histidine kinase and the adaptor protein CheW processes environmental stimuli to regulate motility. The structure of a Thermotoga maritima receptor cytoplasmic domain defines CheA interaction regions and metal ion–coordinating charge centers that undergo chemical modification to tune receptor response. Dimeric CheA–CheW, ...
متن کاملV 407 Vul : a direct impact accretor
V407 Vul (= RXJ1914.4+2457) shows pulsations in X-ray flux on a period of 9.5 minutes, which have been ascribed to accretion onto a magnetic white dwarf, with the X-ray pulses seen as the accreting pole moves into and out of view. The X-ray flux drops to zero between pulses, and no other periods are seen, suggesting that V407 Vul is a type of system known as a “polar” in which the white dwarf h...
متن کامل400-407 Ciancaglini:Shoja
The toxicity of preservatives on conjunctival epithelium has been widely described in glaucomatous patients topically treated, suggesting both an indirect effect on the lacrimal film and a direct toxic action on epithelial cells (1). Previous studies indicate that long-term administration of preservative-containing eyedrops can lead to chronic conjunctival inflammation, ocular surface impairmen...

Hepatocytes provide an integrated model to study drug metabolism and disposition. As a result of a loss of polarity or a significant decrease in the expression of enzymes and transporters, suspended and sandwich-cultured hepatocytes have limitations in determining hepatocellular drug concentrations. Underprediction of the extent of glucuronidation is also a concern for these hepatocyte models. ...
