vitamin d deficiency is common among the elderly with and without heart failure (hf). this study was designed to identify the degree of vitamin d deficiency among hf and non- hf elderly with cardiovascular disease. in this study, fifty hospitalized elderly patients with hf (26 women and 24 men, age range 60-90 years) and fifty elderly without hf were randomly selected. the level of serum 25-hyd...

A distinctive syndrome caused by hypermucoviscous Klebsiella pneumoniae (HMKP) including pyogenic liver abscess (PLA) is now becoming a globally emerging disease. In the present study, 22.8% (84/369) of K. pneumoniae clinical isolates associated with various types of invasive infections were identified as HMKP, with 45.2% associated with PLA. Multivariate regression analysis showed that male pa...

In this paper, highly sensitive methods for measuring of vitamin K in serum, feces and milk are described. Vitamin K1 and the menaquinone family from the serum, feces and milk were separated by high performance liquid chromatography. The separated K1 and menaquinone families were detected by a fluorescence spectrophotometer after their reduction with sodium borohydride or platinum catalyst colu...

This work considers recovery of signals that are sparse over two bases. For instance, a signal might be sparse in both time and frequency, or a matrix can be low rank and sparse simultaneously. To facilitate recovery, we consider minimizing the sum of the l1-norms that correspond to each basis, which is a tractable convex approach. We find novel optimality conditions which indicates a gain over...

We consider a (semi-)relativistic spin-1/2 particle interacting with quantized radiation. The Hamiltonian has the form Ĥ c := {c2[(p + A) +σ ·B] + (mc2)2}1/2 −mc2 +V +Hf . Assuming that the potential |V | is bounded with respect to the momentum |p|, we show that Ĥ c converges in norm-resolvent sense to the usual Pauli-Fierz operator when c, the speed of light, tends to ∞.

Objective(s): Heart failure (HF) is one of the leading causes of death worldwide. Due to beneficial effects of stem cells, paracrine secretion of them has recently been used by researchers. The purpose of this study was to investigate the effects of intravenous injection (IV) of conditioned medium (CM) of human amniotic membrane-derived mesenchymal stem cell (MSC-CM) o...

In this study we define the proliferative compartments of in vivo human epidermis, using specific antibodies related to cell differentiation (beta 1 and beta 4 integrins and K1/K10 differentiation keratins) and cell cycle (proliferating cell nuclear antigen [PCNA]) in combination with flow cytometric quantitation of the DNA content and optical characteristics of the cells. The beta 1 integrin (...

In this issue of the Journal, Yeh et al [1] revisit the importance of magA in Kleb-siella pneumoniae causing pyogenic liver abscess, as well as its exact role in serotype K1 capsule formation. The mucoviscosity-associated gene A (magA) of K. pneumo-niae was originally discovered in 2002 by me and my colleagues [2, 3] in tissue-invasive K. pneumoniae strains causing primary liver abscess complic...

We give a simple representation of all elements in K1 of a Waldhausen category and prove relations between these representatives which hold in K1.
