Let τD(Z) be the first exit time of iterated Brownian motion from a domain D ⊂ Rn started at z ∈ D and let Pz [τD(Z) > t] be its distribution. In this paper we establish the exact asymptotics of Pz[τD(Z) > t] over bounded domains as an improvement of the results in [12, 24], for z ∈ D lim t→∞ t exp( 3 2 πλ 2/3 D t )Pz[τD(Z) > t] = C(z), where C(z) = (λD2 7/2)/ √ 3π (

Pz-peptidase was purified from rat testis and rabbit muscle. Zinc was detectable in the rat enzyme. The activity of the enzyme from both species was slowly but completely abolished by EDTA and restored by Zn2+. Free thiol groups were also important for the catalytic activity of rat Pz-peptidase, as previously reported for the rabbit enzyme. We conclude that in both species Pz-peptidase has the ...

histologically. Some authors suggested that the hyperplastic nodules in the PZ might be exophytic BPH in the TZ or the migration of ectopic TZ tissue into the PZ. The authors of the present study speculate that it is more likely that the hyperplastic nodules might originate from the PZ. In the present study, the epithelial, stromal and luminal composition of the tissue was determined using a co...

Protein Z (PZ) binds to PZ-dependent inhibitor (ZPI) and accelerates the inhibition of the coagulation protease, activated factor X (FXa), in the presence of phospholipids and Ca2+. A 2.3A resolution crystal structure of PZ complexed with ZPI shows that ZPI is a typical serine protease inhibitor and that PZ has a serine protease fold with distorted oxyanion hole and S1 pocket. The 2 molecules b...

The study aim was to investigate the situations of the carotid Intima-Media Thickness (cIMT) and atherosclerotic plaques in the patients with Cerebral Infarction (CI) as well as their correlations with Plasma protein Z (PZ) and Fibrinogen (FIB). 75 CI patients and 35 non-CI patients were performed carotid ultrasonography to measure their cIMT and to observe the situations of atherosclerotic pla...

Early transection and stimulation studies suggested the existence of sleep-promoting circuitry in the medullary brainstem, yet the location and identity of the neurons comprising this putative hypnogenic circuitry remains unresolved. In the present study, we sought to uncover the location and identity of medullary neurons that might contribute to the regulation of sleep. Here we show the follow...

In lattice-QCD calculations of parton distribution functions (PDFs) via large-momentum effective theory, the leading power (twist-three) correction appears as O(ΛQCD/Pz) due to linear-divergent self-energy Wilson line in quasi-PDF operators. For lattice data with hadron momentum Pz a few GeV, this is dominant matching, large 30% or more. We show how eliminate uncertainty through choosing mass r...

E. senticosus extract (ESE), known as antioxidant, has diverse pharmacologic effects. It is also used as an antiaging agent for the skin and phlorizin (PZ) is identified as a main ingredient. In this study, the effects of PZ on epidermal stem cells were investigated. Cultured normal human keratinocytes and skin equivalents are used to test whether PZ affects proliferative potential of keratinoc...

The heretofore unknown emission properties of the metal-to-ligand charge-transfer (MLCT) excited states of several complexes with (ruthenium)(monodentate aromatic ligand, MDA) chromophores are given. Emission spectra and lifetimes in 77 K glasses are reported for several monometallic complexes of the type [Ru(NH3)(5-n)(L)(n)(MDA)](2+) and two bimetallic pyrazine (pz)-bridged [{Ru(NH3)(4-n)(L)(n...

Self-consistent calculations using the Perdew-Zunger self-interaction correction (PZ-SIC) to local density and gradient dependent energy functionals are presented for the binding energy and equilibrium geometry of small molecules as well as energy barriers of reactions. The effect of the correction is to reduce binding energy and bond lengths and increase activation energy barriers when bond br...
