The human lens contains three major protein families: α-, β-, and γ-crystallin. Among the several variants of γ-crystallin in the human lens, γD-crystallin is a major form. γD-Crystallin is primarily present in the nuclear region of the lens and contains a single lysine residue at the second position (K2). In this study, we investigated the acetylation of K2 in γD-crystallin in aging and catara...

BACKGROUND The Killip classification categorizes heart failure (HF) in acute myocardial infarction, and has a prognostic value. Although non-ST-elevation myocardial infarction (NSTEMI) is increasing steadily, little information is available about the prognostic value of low Killip class in this scenario. Our aim was to assess the prognostic value of mild HF in NSTEMI. METHODS 835 patients wit...

BACKGROUND AND PURPOSE Contrast leakage results in underestimation of the CBV of brain tumors. Our aim was to compare the diagnostic performance of DSC perfusion MR imaging without and with mathematic contrast-leakage correction in differentiating PCNSLs and glioblastomas. MATERIALS AND METHODS Perfusion parameters-CBV, corrected CBV, and leakage coefficient-were measured in enhancing tumor p...

The purpose of this study was to compare the stroke characteristics of sprint kayakers in team boat (K2) versus individual (K1) 200-m racing. This case study centred on two male 200-m specialists from a national sprint kayak team. High-speed (120 Hz) videos were recorded from the sagittal view during an important selection time trial. Thereafter, video analysis was performed to identify stroke ...

The block cipher DESX is de ned by DESXk:k1:k2(x) = k2 DESk(k1 x), where denotes bitwise exclusive-or. This construction was rst suggested by Ron Rivest as a computationally-cheap way to protect DES against exhaustive key-search attacks. This paper proves, in a formal model, that the DESX construction is sound. We show that, when F is an idealized block cipher, FXk:k1:k2(x) = k2 Fk(k1 x) is sub...

Inositol pyrophosphate diphosphoinositol pentakisphosphate is ubiquitously present in mammalian cells and contains highly energetic pyrophosphate bonds. We have previously reported that inositol hexakisphosphate kinase type 2 (InsP(6)K2), which converts inositol hexakisphosphate to inositol pyrophosphate diphosphoinositol pentakisphosphate, mediates apoptotic cell death via its translocation fr...

The PTB submitted directly to the SIR one ampoule of 166m Ho prepared from a dilution of the solution distributed to four laboratories participating in the EURAMET.RI(II)-K2.Ho-166m comparison in 2013. No attempt to evaluate a new KCRV has been made and the usual procedure was applied to link the results of the comparison to the usual SIR entries through the PTB. One NMI used this K2 comparison...

Let K be a prime knot and G(K) its knot group. It is well known that a partial order can be defined on the set of prime knots as follows: for two knots K1,K2, we write K1 ≥ K2 if there exists a surjective group homomorphism from G(K1) onto G(K2). In this paper, we determine this partial order “≥” on the set of knots in Rolfsen’s knot table, which lists all the prime knots of ten crossings or le...

Let G H and G2H denote, respectively, the strong and Cartesian products of graphs G and H . (We recall that K2 K2 is the complete graph K4 on four vertices, while K22K2 is a four-cycle C4.) Using a simple construction, we show that, for every bipartite G, the graph G K2 is a minor of the graph G2C4. In particular, the d-cube Qd has a complete minor on 2 (d+1)/2 vertices if d is odd, and on 3 · ...

Recently, Azarija et al. considered the prism G K2 of a graph G and showed that γt(G K2) = 2γ(G) if G is bipartite, where γt(G) and γ(G) are the total domination number and the domination number of G. In this note, we give a simple proof and observe that there are similar results for other pairs of parameters. We also answer a question from that paper and show that for all graphs γt(G K2) ≥ 4 3...
