BACKGROUND In the chronic kidney disease (CKD) population, the impact of serum potassium (sK) on renal outcomes has been controversial. Moreover, the reasons for the potential prognostic value of hypokalemia have not been elucidated. DESIGN PARTICIPANTS & MEASUREMENTS 2500 participants with CKD stage 1-4 in the Integrated CKD care program Kaohsiung for delaying Dialysis (ICKD) prospective obs...

We study the skewness premium (SK) introduced by Bates (1991) in a general context using Lévy Processes. Under a symmetry condition Fajardo and Mordecki (2006) obtain that SK is given by the Bate’s x% rule. In this paper we study SK under the absence of that symmetry condition. More exactly, we derive sufficient conditions for SK to be positive, in terms of the characteristic triplet of the Lév...

BACKGROUND Seborrheic keratosis (SK) is one of the most common epidermal tumors of the skin. However, only a few large-scale clinicohistopathological investigations have been conducted on SK or on the possible correlation between histopathological SK subtype and location. OBJECTIVE The aim of this study was to analyze the clinical and histopathological features of a relatively large number of...

Trypsin-activated pig plasmin and human plasmin activated by streptokinase (SK) caused aggregation of a suspension of washed platelets from human, rabbit, or pig blood. The platelet aggregation was reversible, but it was accompanied by a significant release of adenine nucleotides, serotonin, and platelet fibrinogen. Platelet fibrinogen was eventually digested. The effect of plasmin on platelets...

1. SK channels are small-conductance calcium-activated potassium channels that are widely expressed in neurons. The traditional view of the functional role of SK channels is in mediating one component of the after-hyperpolarization that follows action potentials. Calcium influx via voltage-gated calcium channels active during action potentials opens SK channels and the resultant hyperpolarizati...

Sulfakinins (SKs) are a family of multifunctional neuropeptides that have been shown to have myotropic activity on muscles of the digestive system and to function as feeding satiety factors. Here, we confirm via cloning the presence of two sulfakinins (Rhopr-SK-1 and Rhopr-SK-2) in Rhodnius prolixus. Reverse transcriptase quantitative PCR demonstrates that the Rhopr-SK transcript is highly expr...

Let sk = 1 √ N (v1k, . . . , vNk) T , k = 1, . . . ,K, where {vik, i, k = 1, . . .} are independent and identically distributed random variables with Ev11 = 0 and Ev 2 11 = 1. Let Sk = (s1, . . . , sk−1, sk+1, . . . , sK), Pk = diag(p1, . . . , pk−1, pk+1, . . . , pK) and βk = pks T k (SkPkS T k + σ 2 I)sk, where pk ≥ 0 and the βk is referred to as the signal-to-interference ratio (SIR) of user...

1.1 Small and semismall maps Let f : X → Y be a proper surjective map of varieties with X nonsingular. We say that a decomposition of Y = ⊔ k Sk into finitely many non-singular locally closed subvarieties Sk is a stratification relative to f if each restriction f : f(Sk)→ Sk is a topological locally trivial fibration. Proposition 1.1. The following conditions are equivalent. (a) Rf∗CX [dimX] is...

In 2001, Boneh and Franklin presented the first efficient and security-proved identity-based encryption scheme using pairing on elliptic curve. In 2003 Sakai and Kasahara proposed another IBE scheme with pairing, which has the potential to improve performance. Later, Chen and Cheng proved the security of a variant of Sakai and Kasahara’s scheme. While, both the security-provable schemes employ ...
