Circulating levels of vitamins K1 and K2 decreased in elderly women with hip fracture

We measured the serum levels of phylloquinone (vitamin K1) and of the menaquinones, MK-7 and MK-8, in a group of 51 women with a mean age of 81 years who were studied within a few hours after a hip fracture. A group of 38 healthy age-matched women randomly chosen from the same population served as controls. Patients with hip fracture had a marked reduction in serum vitamin K1 (336 +/- 302 versus 5

Diagonalization of the neutralino mass matrix and boson-neutralino interaction

We analyze a connection between the neutralino mass sign, parity and structure of the neutralino-boson interaction. Correct calculation of spin-dependent and spin-independent contributions to neutralino-nuclear scattering should consider this connection. A convenient diagonalization procedure, based on the exponential parametrization of unitary matrix, is suggested.

Scalar Higgs boson production in fusion of two off-shell gluons

The amplitude for scalar Higgs boson production in the fusion of two off-shell gluons is calculated including finite (not infinite) masses of quarks in the triangle loop. In comparison to the effective Lagrangian approach, we have found a new term in the amplitude. The matrix element found can be used in the k⊥-factorization approach to the Higgs boson production. The results are compared with the

Inner valence region of CO adsorbed on Pd(100)

The inner valence region of CO/Pd(100) p(2√2×√2)R45° has been studied by angular resolved photoemission at the Pd 4d Cooper minimum, and with resonant Auger spectroscopy at photon energies corresponding to the C 1s and O 1s x-ray absorption (XA) maxima of the unoccupied parts of the 2π*-Pd 4d hybrid (2πun). Previously unobserved inner valence states are revealed in the direct photoemission and are

Surface and bulk core level binding energy shifts in PtAu alloys

The surface core level shift of the 4f 7 2 level in a Pt2%Au and a Pt15%Au alloy has been investigated using high resolution synchrotron radiation excited photoelectron spectroscopy. The bulk and surface components in the recorded spectra have been extracted using a curve fitting procedure. The chemical shifts and the bulk-to-surface intensity ratios are consistent with a strong enrichments of Au

Surface core level shift of the Be 1s level observed from a Be(0001) single crystal surface

We have used surface sensitive photoelectron spectroscopy to study the Be 1s core level from the Be(0001) single crystal surface. Two core peaks are observed, one from the bulk atoms, and the other from the first layer surface atoms. They are separated in binding energy by 0.50 eV, the surface peak being located at lower binding energy. This experimental surface core level shift (SCS) is compared

Knowledge Base Combinations and Innovation Performance in Swedish Regions

The literature on geography of innovation suggests that innovation outcomes depend on a diversity of knowledge inputs, which can be captured with the differentiated knowledge base approach. While knowledge bases are distinct theoretical categories, existing studies stress that innovation often involves combinations of analytical, synthetic, and symbolic knowledge. It remains unclear, though, which

Chicken parathyroid hormone gene expression in response to gastrin, omeprazole, ergocalciferol, and restricted food intake.

Treatment with omeprazole, a long-acting proton pump inhibitor of acid secretion, induces hypergastrinemia. In chickens, omeprazole induces growth not only of the acid-producing mucosa (probably reflecting the trophic action of gastrin), but also of the parathyroid glands (hypertrophy + hyperplasia), while suppressing bone density and body weight gain without affecting blood calcium. The first par

Several cases of undesirable effects caused by methacrylate ultraviolet-curing nail polish for non-professional use

Background: Ultraviolet (UV)-curing nail polishes based on acrylates or methacrylates are currently also available for non-professional use. The Swedish Medical Products Agency recently prohibited one brand of UV-curing polish, because several consumers reported undesirable effects after using it. Objectives: To investigate whether consumers with undesirable effects after using the UV-curing nail

How do carriers of hemophilia experience prenatal diagnosis (PND)? : Carriers' Immediate and later reactions to amniocentesis and fetal blood sampling

A semistructured personal interview was performed with 29 carriers of hemophilia A or B, 1-5 years after a pregnancy in which prenatal diagnosis (PND) was performed by fetal blood sampling. Fetal blood sampling by fetoscopy was significantly more often reported by the women to the more trying than expected than was ultrasound-guided heart puncture. Of 29 women 13 was classified as having experienc
