Aim. A new manufacturing method aiming at to producing more flexible and resistant NiTi endodontic instruments has been recently developed (Hyflex, produced with CM wire). The purpose of the study was to determine whether this new manufacturing method produces NiTi instruments (Hyflex) of superior flexibility and/or superior resistance to cyclic fatigue, when compared with instruments produced ...
We study complexified Harmonic Oscillator with a position dependent mass, referred to in the present paper as Exotic Oscillator (EO), in arbitrary dimensions. The real space EO has an interesting dynamics: in the equation of motion the full Hamiltonian operator appears in place of the frequency parameter in a Harmonic Oscillator. We reveal some generic features in the constraint structure of th...
OBJECTIVE The objective of the present study was to explore the major risk factors of surgical complications using the Clavien-Dindo classification. METHODS The case-control design was used. A total of 1049 patients who underwent radical gastrectomy in Hunan Cancer Hospital between October 2010 and August 2014 were retrospectively analyzed, including 122 patients (11.6%) with complications an...
multiple sclerosis (ms) is an inflammatory and autoimmune disease.ms is characterized by blood brain barrier breakdown, inflammation, axonal injury, degeneration of the myelin sheath and etc. a significant association between inflammation and degeneration of neurons is observed in the brain. also active ms lesions always associated with inflammation thus inflammation is a target for treatment o...
Background. Liver ischemia-reperfusion (IR) injury is one of the chief etiologies of tissue damage during liver transplantation, hypovolemic shock, and so forth. This study aimed to evaluate hepatoprotective effect of crocin on IR injury and on microRNAs (miR-122 and miR-34a) expression. Materials and Methods. 32 rats were randomly divided into four groups: sham, IR, crocin pretreatment (Cr), a...
The productivity of a perennial lupin/cocksfoot mix was compared to that of lucerne in summer dry conditions at Lincoln University, Canterbury, New Zealand. The pastures were planted in December 2013 and rotationally grazed by ewe lambs in autumn 2014 (Year 1), and by ewe hoggets in spring-summer and ewe lambs in autumn of 2014/2015 (Year 2) and 2015/2016 (Year 3). For lupin/cocksfoot relative ...
Objective Tolvaptan was first approved for use for cirrhosis in Japan in September 2013. The aim of the study was to examine the effect of tolvaptan, a vasopressin V2 receptor antagonist, on the prognosis of cirrhosis. Methods The effect of tolvaptan was evaluated in 26 patients with cirrhosis treated at our hospital from September 2013 to April 2015. Results The primary disease was hepatitis C...
