Methoxamine Induced “Non-paradoxical” Reversed Splitting

Caffeine attenuates paradoxical sleep deprivation induced- memory impairment during paradoxical sleep windows in rats

There is considerable evidence to support the hypothesis of relationship between paradoxical sleep (PS) and learning–memory processing. It has been suggested that PS is important in memory retention at the specific time course called PS windows (PSW). The time of PSWs occurrence and duration of these PSWs following the training sessions and, the neurochemical nature of PSWs has not been well kn...

Methoxamine in Anesthetized Dogs

We studied effects on venous return of aand /8-adrenergic agonists in anesthetized dogs. Blood from the superior and inferior venae cavae (venous return) was drained at the level of the tricuspid valve into a reservoir, from which blood was pumped into the right atrium at a constant rate. Isoproterenol infused into the ascending aorta or the right atrium increased the venous return and heart ra...

Non-Singlet Partonic Splitting Functions

We develop a simplified method for obtaining higher orders in the perturbative expansion of the singular term A (αs) /[1−x]+ of non-singlet partonic splitting functions. Our method is based on the calculation of eikonal diagrams. The key point is the observation that the corresponding cross sections exponentiate in the case of two eikonal lines [1, 2, 3], and that the exponent is directly relat...
