capillary electrophoresis (ce) with indirect uv detection is an interesting analytical method for the analysis of drugs and pharmaceuticals. good and reproducible capillary quality is needed to develop robust methods and to facilitate method transfer in ce. it is widely accepted that preconditioning procedures are indispensable in capillary electrophoresis in order to achieve reproducibility of...

BACKGROUND AND PURPOSE An M-shaped bifid notch on the ascending branch, or on the zenith, of the R wave in inferior ECG leads (II, III, aVF), so called "crochetage," is an indicator of ostium secundum atrial septal defects. The pathophysiology underlying this finding remains unknown. A crochetage pattern has not been previously reported in patients with patent foramen ovale (PFO); however, the ...

In this paper we prove that there exists an absolute constant c > 0 such that for every natural number k, every non-bipartite 2-connected graph with average degree at least ck contains k cycles with consecutive odd lengths. This implies the existence of the absolute constant d > 0 that every non-bipartite 2-connected graph with minimum degree at least dk contains cycles of all lengths modulo k,...

As the counterpart of classical theorems on cycles consecutive lengths due to Bondy and Bollobás in spectral graph theory, Nikiforov proposed following open problem 2008: What is maximum C $C$ such that for all positive ε < $\varepsilon \lt C$ sufficiently large n $n$ , every G $G$ order with radius ρ ( ) > ⌊ 2 4 ⌋ $\rho (G)\gt \sqrt{\lfloor \frac{{n}^{2}}{4}\rfloor }$ contains a cycle length ℓ...

hepatomegaly, decrease in the liver paranchymal echo and increase in the gallbladder wall thickness has been shown in acute viral hepatitis. the present study was done to determine sonographic changes in acute viral hepatitis. we performed liver and bile ducts sonography and specific tests on 42 patients (mean age: 31.5 and 61% male) with acute viral hepatitis. gallbladder wall thickness was se...

Background: Heavy menstrual bleeding is a leading cause of poor quality of life and iron deficiency anemia in reproductive aged women. The aim of this study was to compare the efficacy and acceptability of Medroxyprogestrone acetate and Tranexamic acid in menorrhagia management. Materials and Methods: Inclusion criteria were: age 20-45 years, regular menses, not using hormonal drugs for previou...
