Sub-Saharan Africa is endemic for Kaposi’s sarcoma-associated herpesvirus (KSHV) and there is a high rate of early childhood infection; however, the transmission sources are not well characterized. We examined household members as potential KSHV transmission sources to young children in the KSHV-endemic country of Zambia. To this end, we enrolled and followed Zambian households with at least on...

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...

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.

Currently, there are few guidelines for the use of vitamin K1 in the maintenance treatment of long-acting anticoagulant rodenticide (LAAR) poisonings. We explored factors in the treatment of LAAR poisoning during the maintenance period in order to suggest feasible treatment models.Data from 24 cases of anticoagulant rodenticide poisoning in our hospital were collected from January 2013 to May 2...
