An in vitro aggregation of washed lutoid membrane and rubber particles, respectively, prepared from the bottom (lutoid) fraction and rubber layer of centrifuged fresh latex, leading to the formation of rubber coagulum necessary for a latex coagulation was demonstrated. A Triton X-100 extract of washed lutoid membrane proteins, isolated and prepared from the bottom fraction of centrifuged fresh ...

The conformational dynamics of Humicola lanuginosa lipases (HLL) and its three mutants were investigated by steady state and time-resolved fluorescence spectroscopy in two different media, aqueous buffer and the substrate triacetin. The fluorescence of the four Trps of the wild-type HLL (wt) reports on the global changes of the whole lipase molecule. In order to monitor conformational changes s...

Chronic hypoxia is associated with both blunted agonist-induced and myogenic vascular reactivity and is possibly due to an enhanced production of heme oxygenase (HO)-derived carbon monoxide (CO). However, the mechanism of endogenous CO-meditated vasodilation remains unclear. Isolated pressurized mesenteric arterioles from chronically hypoxic rats were administered the HO substrate heme-l-lysina...

Carbon monoxide (CO) is an endogenous dilator in the newborn cerebral microcirculation. Other dilators include prostanoids and nitric oxide (NO), and interactions among the systems are likely. Experiments on anesthetized piglets with cranial windows address the hypothesis that CO-induced dilation of pial arterioles involves interaction with the prostanoid and NO systems. Topical application of ...

Here we give a detailed proof for the crucial point in our Minsky machine simulation - that any linear logic derivation for a specific Horn sequent can be transformed into a Minsky computation leading from an initial configuration to the halting configuration. Among other things, the presentation advantage of the 3-step program is that the non-trivial tricky points are distributed between the i...
