We aimed to evaluate the effects of the barrier agent sodium carboxymethyl cellulose (SCMC) with and without dexamethasone for the prevention of postoperative adhesion formation in a rat model of postoperative peritoneal adhesion. A total of 160 three-month old male and female Wistar rats underwent a laparotomy, and adhesions were induced by ileocecal abrasion. Rats were randomly assigned to 4 ...

Let φ : Cn×Cn → C, φ((x1, ..., xn), (y1, ..., yn)) = (x1−y1)+ ...+ (xn − yn). We say that f : Rn → Cn preserves distance d ≥ 0 if for each x, y ∈ Rn φ(x, y) = d2 implies φ(f(x), f(y)) = d2. We prove that if x, y ∈ Rn (n ≥ 3) and |x − y| = ( √ 2 + 2/n)k · (2/n)l (k, l are nonnegative integers) then there exists a finite set {x, y} ⊆ Sxy ⊆ Rn such that each unit-distance preserving mapping from S...

We tested the hypothesis that conduction velocity of quiescent muscle fibers decreases during sustained contraction due to the activity of the active motor units in the muscle. Ten subjects trained for the identification of a target motor unit in the abductor pollicis brevis with feedback on surface EMG signals detected with a two-dimensional array of 61 electrodes. The subjects activated the t...

Aim: To study the C1-2 facets in patients with congenital atlantoaxial dislocation and their bearing on the presentation and management. Materials and methods: Thirty-six patients of congenital AAD were studied in the last 2 years. Twenty-four patients had irreducible AAD (not reducing on traction) and remaining 12 had redu cible AAD. Computed tomography (CT) scans were obtained and the C1-2 jo...

(a) Prove that the sum and product of abstract symbols is well-defined. That is, if [a1, b1] = [a2, b2] and [c1, d1] = [c2, d2], prove that we have [a1, b1] · [c1, d1] = [a2, b2] · [c2, d2] and [a1, b1] + [c1, d1] = [a2, b2] + [c2, d2] . (b) One can check that Q satisfies all of the axioms of Z except for the Well-Ordering Axiom (please don’t check this), with additive identity [0, 1] ∈ Q and m...

OBJECTIVE Atlantoaxial stability can be achieved by laminar hook systems via posterior approach. This technique is much more safer than using screws. We presented our experience with the C1-C2 claw procedure. METHODS AND MATERIAL Seven patients with atlantoaxial instability were operated by using C1 and C2 hooks, rods and transverse connector at Neurosurgery Clinic of Istanbul University Cerr...

A calibration-based technique for real-time measurement of pyruvate polarization by partial integral analysis of the doublet from the neighbouring J-coupled carbon is presented. In vitro calibration data relating the C2 and C1 asymmetries to the instantaneous C1 and C2 polarizations, respectively, were acquired in blood. The feasibility of using the in vitro calibration data to determine the in...

The influences of spatial frequency distributions on complete amplitude death are explored by studying an array of diffusively coupled oscillators. We found that with all possible sets of spatial frequency distributions, the two critical coupling strengths ε(c1) (lower-bounded value) and ε(c2) (upper-bounded value) needed to get complete amplitude death exhibit a universal power law and a log-n...

Let C ⊂ C1 ×C2 be a curve of type (d1, d2) in the product of the two curves C1 and C2. Let ν be a positive integer. We prove that if a certain inequality involving d1, d2, ν, and the genera of the curves C1, C2, and C is satisfied, then the set of points {P ∈ C(k̄) | [k(P ) : k] ≤ ν} is finite for any number field k. We prove a similar result for integral points of bounded degree on C. These res...
