OBJECTIVE The aim of the present 12-weeks follow-up randomized clinical trial was to investigate the outcome of mechanical curettage (MC) with or without adjunct antimicrobial photodynamic therapy (aPDT) in the treatment of peri-implant mucositis in cigarette smokers. METHODS Therapeutically, subjects with peri-implant mucositis were divided into 2 groups: (a) Group-A: MC+aPDT; and (b) Group-...
INTRODUCTION Transrectal rectal ultrasound (TRUS)-guided systematic biopsy is the gold standard for diagnosis of prostate cancer. However, systematic biopsy has high false-negative rate and often misses anteriorly located tumors. Magnetic resonance imaging (MRI)-TRUS fusion biopsy can potentially improve cancer detection by better visualization and targeting of cancer focus. We evaluated the ro...
In this paper some upper and lower bounds for the greatest eigenvalues of the PI and vertex PI matrices of a graph G are obtained. Those graphs for which these bounds are best possible are characterized.
This work presents hysteresis control applied to UXE-type inverter topology with a PI (Proportional Integral) controller, where the gains are derived by Particle Swarm Optimization (PSO). The investigated UXE can generate thirteen-level output voltage waveform, which results in lower switching losses. It boost 1.5 times input DC source voltage. Satisfactory operation is ensured employing twelve...

Elevated levels of phosphate (Pi) reduce isometric force, providing support for the notion that the release of Pi from myosin is closely associated with the generation of muscular force. Pi is thought to rebind to actomyosin in an ADP-bound state and reverse the force-generating steps, including the rotation of the lever arm (i.e., the powerstroke). Despite extensive study, this mechanism remai...
Abnormalities of lung function have previously been described in patients with impaired alpha 1-protease inhibitor (alpha 1-PI) function and more recently in insulin-dependent diabetic subjects. This study was undertaken to test the hypothesis that impaired alpha 1-PI activity may be implicated in the pathogenesis of lung function abnormalities in young insulin-dependent diabetic patients. Twel...
