A newly introduced compound, EPC-K1, represents a phosphate diester linkage of vitamin E and vitamin C. The effect of EPC-K1 on the reperfusion injury was evaluated in a heterotopic cardiac transplantation model using syngenic combination rats. Prior to the warm ischemia, 12mg EPC-K1/kg was administered intravenously to donor rats. After 15 min of warm ischemic time, hearts were harvested and p...

Two classes of phages yield profoundly different levels of recovery in mice experimentally infected with an Escherichia coli O18:K1:H7 strain. Phages requiring the K1 capsule for infection (K1-dep) rescue virtually all infected mice, whereas phages not requiring the capsule (K1-ind) rescue modest numbers (∼30%). To rescue infected mice, K1-ind phages require at least a 10(6)-fold-higher inoculu...

Background In the past two decades, Vitamin K has been receiving more attention due to its role in bone health and metabolism. The bone mineral density does not remain steady with age, particularly declining after menopause. Objective This study is aimed to investigate the relationship between bone mineral density and serum vitamin K1 levels in post-menopausal women, and to evaluate serum vit...

Juel, C., H. Pilegaard, J. J. Nielsen, and J. Bangsbo. Interstitial K1 in human skeletal muscle during and after dynamic graded exercise determined by microdialysis. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R400– R406, 2000.—Interstitial K1 concentrations were measured during one-legged knee-extensor exercise by use of microdialysis with probes inserted in the vastus lateralis...

Physiol. 277 (Cell Physiol. 46): C280–C287, 1999.—Functional expression of the rat colonic H1-K1-ATPase was obtained by coexpressing its catalytic a-subunit and the b1-subunit of the Na1-K1-ATPase in Xenopus laevis oocy...

Closely related Escherichia coli B2 strains O1:K1, O2:K1, O18:K1, and O45:K1 constitute a major subgroup causing extraintestinal infections. A DNA pathoarray analysis was used to develop a PCR specific for this subgroup that was included in the multiplex phylogenetic-grouping PCR method. Our PCR may serve to identify this virulent subgroup among different ecological niches.

Let K be a knot in the 3–sphere S3 , t(K) the tunnel number of K and K1#K2 the connected sum of two knots K1 and K2 , where t(K) is the minimal genus −1 among all Heegaard splittings which contain K as a core of a handle. Concerning the relationship between t(K1)+ t(K2) and t(K1#K2), we showed in Morimoto [2] that there are infinitely many tunnel number two knots K such that t(K#K′) is two agai...

We show that K1(E) of an exact category E agrees with K1(DE) of the associated triangulated derivator DE under the hypothesis of the GilletWaldhausen theorem. More generally we show that K1(C(E)) of the category of bounded complexes in E always coincides with K1(DE).
