We study the non-leptonic two-body weak decays of ?b0?pM with M=(??,K?) and (??,K??) in light-front quark model under generalized factorization ansatz. By considering Fermi statistic between quarks determining spin-flavor structures baryons, we calculate branching ratios (Bs) CP-violating rate asymmetries (ACPs) decays. Explicitly, find that B(?b0?p??,pK?)=(4.18±0.15±0.30,5.76±0.88±0.23)×10?6 A...

Boar spermatozoa contain a novel pyruvate kinase (PK-S) that is tightly bound at the acrosome of the sperm head and at the fibrous sheath in the principal piece of the flagellum, while the midpiece contains a soluble pyruvate kinase (PK). PK-S could not be solubilized by detergents, but by trypsin with no loss of activity. Purified PK-S as well as PK-S still bound to cell structures and soluble...

Developmental and aging patterns of pyruvate kinase (PK) isozymes (PK 1, PK 2, PK 3, and PK 4) from rat liver, kidney, heart, and skeletal muscle were studied by electrophoretic, chromatographic and immunochemical techniques. During the first 2 weeks of postnatal life a decline of total PK activity occurred in liver, kidney, and heart followed by an increase to adult or higher than adult levels...

The aim of this paper is to construct (p,q)-calculus on finite intervals. (pk,qk)-derivative and (pk,qk)-integral are defined some basic properties given. Also, (pk,qk)-analogue H?lder, Minkowski integral inequalities proved.

The acidic dissociation constants in the range HO--1.5 to pH 7 of folic acid, dihydrofolic acid, methopterin (N(10)methylfolic acid), and methotrexate have been measured by potentiometric and spectrophotometric titrations. Assignment of these dissociations was made by comparison to model compounds, by proton magnetic resonance measurements, and by examination of associated ultraviolet absorbanc...

purpose: to compare clinical outcomes of two methods of corneal transplantation, penetrating keratoplasty (pk) versus lamellar keratoplasty (lk), in patients with delayed-onset mustard gas keratitis (mgk). methods: in this retrospective, comparative, interventional case series, 78 eyes of 55 victims of chemical warfare with delayed-onset mustard gas keratopathy who underwent pk or lk were enrol...

purpose : glaucoma following penetrating keratoplasty (pk) continues to be a serious problem that may ultimately become sight threatening. knowledge of the risk factors for development of glaucoma following pk, such as preexisting glaucoma, pseudophakia, aphakia, and previous pk, can limit the occurrence and improve the outcome of the keratoplasty. the management of postkeratoplasty (post-pk) g...
