We have examined endogenous cyclic AMP-stimulated phosphorylation of subcellular fractions of rat brain enriched in synaptic plasma membranes (SPM), purified synaptic junctions (SJ), and postsynaptic densities (PSD). The analyses of these fractions are essential to provide direct evidence for cyclic AMP-dependent endogenous phosphorylation at discrete synaptic junctional loci. Protein kinase ac...

BACKGROUND The aim of the present study was to verify concurrent validity of the Gyko inertial sensor system for the assessment of vertical jump height. METHODS Nineteen female sub-elite youth soccer players (mean age: 14.7 ± 0.6 years) performed three trials of countermovement (CMJ) and squat jumps (SJ), respectively. Maximal vertical jump height was simultaneously quantified with the Gyko s...

Liver fibrosis induced by Schistosoma japonicum (Sj) infection is characterized by the accumulation of extracellular matrix (ECM). The activated and differentiated hepatic stellate cells (HSCs) are the predominant ECM-producing cell type in the liver. Toll-like receptor (TLR) 4 pathway activation plays a key role in mice liver fibrosis models induced by alcohol, biliary ligation, and carbon tet...

PURPOSE To Study the dosimetric advantage of the Jaw tracking technique in intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT) for Head and Neck Cancers. MATERIALS AND METHODS We retrospectively selected 10 previously treated head and neck cancer patients stage (T1/T2, N1, M0) in this study. All the patients were planned for IMRT and VMAT with simultaneous inte...

The origin of this study is the 1993 International Mathematical Olympiads, held at Istanbul, Turkey. Problem # 6, which occurred on day 2, reads: Let n > 1 be an integer. There are n lamps L0, . . . , Ln−1 arranged in a circle. Each lamp is either ON or OFF. A sequence of steps S0, S1, . . . , Sj , . . . is carried out. Step Sj affects the state of Lj only (leaving the state of all others lamps...

We consider an infinite sequence of items of types C = {c1, . . . , cI}, and another infinite sequence of items of types S = {s1, . . . , sJ}, and a bipartite graph G of allowable matches between the types. Matching the two sequences on a first come first served basis defines a unique infinite matching between the sequences. For (ci, sj) ∈ G we define the matching rate rci,sj as the long term f...

The gene networks regulating heart morphology and cardiac integrity are largely unknown. We previously reported a role for the heterotrimeric G protein gamma subunit 1 (Ggamma1) in mediating cardial-pericardial cell adhesion in Drosophila. Here we show G-oalpha47A and Gbeta13F cooperate with Ggamma1 to maintain cardiac integrity. Cardial-pericardial cell adhesion also relies on the septate junc...

The knee range of motion is an important outcome of total knee arthroplasty (TKA). According to previous studies, the knee range of motion temporarily decreases for approximately 1 month after TKA due to postoperative pain and quadriceps dysfunction following surgical invasion into the knee extensor mechanism. We describe our experience with a knee-extension training program based on a single-j...

Let z be a real quadratic irrational. We compare the asymptotic behavior of Dedekind sums S(pk, qk) belonging to convergents pk/qk of the regular continued fraction expansion of z with that of Dedekind sums S(sj/tj) belonging to convergents sj/tj of the negative regular continued fraction expansion of z. Whereas the three main cases of this behavior are closely related, a more detailed study of...

Abstract. An explicit Dirichlet series is obtained, which represents an analytic function of s in the half-plane Rs > 1/2 except for having simple poles at points sj that correspond to exceptional eigenvalues λj of the non-Euclidean Laplacian for Hecke congruence subgroups Γ0(N) by the relation λj = sj(1 − sj) for j = 1, 2, · · · , S. Coefficients of the Dirichlet series involve all class numbe...
