objective: administration of amoxicillin and metronidazole along with scaling and root planning (srp) is an effective adjunctive therapy for chronic periodontitis. studies have shown that administration of azithromycin is also effective for treatment of chronic periodontitis. this study aimed to compare the effect of short-term and long-term azithromycin regimen with amoxicillin and metronidazo...

BACKGROUND The long-term age-related changes in circadian rhythm of heart rate variability (HRV), that is, autonomic nervous activity, remain unknown in elderly people. METHODS AND RESULTS Holter monitoring was conducted twice at an interval of 15 years in 15 healthy elderly patients (age: 70.0 +/- 4.1 years, at first monitoring, female: 10) and assessed the age-related changes in 24-h mean a...

Repeated application of manures to agricultural soils could cause the accumulation of phosphorus (P) in soils. However, it is unclear if manure P can behave similar to P in soluble fertilizers in accumulation Olsen-P (0.5 mol L-1 NaHCO3 at pH 8.5) in soils. A long-term wheat-maize rotation experiment was conducted to investigate the effects of repeated application of manures on P accumulation i...

We describe spine form LF, a version of LF syntactically restricted to canonical forms, and use this framework to begin a logical presentation of the term language used within Twelf, which is (among other things) an implementation of LF. This is not a self-contained document by any means, it is incomplete and furthermore assumes various levels of background in focusing systems, dependent types,...

The aim of this study was to investigate the cardiovascular autonomic acute response, during recovery after handcycle training, in quadriplegics with spinal cord injury (SCI). [Subjects and Methods] Seven quadriplegics (SCIG -level C6-C7, male, age 28.00 ± 6.97 years) and eight healthy subjects (CG -male, age 25.00 ± 7.38 years) were studied. Their heart rate variability (HRV) was assessed befo...

This paper offers a sustainable strategy technoeconomic analysis off-grid hybrid systems (HES) in remote islands Iran, including Lavan, Larak, Failaka, utilizing PV module, wind turbine, hydrokinetic turbines. Hourly speed, solar irradiation, hydrovelocity have been implemente...

Objective. As few, small studies have examined the impact of electroconvulsive therapy (ECT) upon the heart rate variability of patients with major depressive disorder (MDD), we sought to confirm whether ECT-associated improvement in depressive symptoms would be associated with increases in HRV linear and nonlinear parameters. Methods. After providing consent, depressed study participants (n = ...

BACKGROUND We evaluated the effects of the PCM on the fractal analysis of the HRV in healthy women. METHOD We evaluated healthy women between 18 and 30 years old. HRV was analyzed in the time (SDNN, RMSSD, NN50 and pNN50) and frequency (LF, HF and LF/HF ratio) domains as well as short and long-term fractal exponents (alpha-1 and alpha-2) of the detrended fluctuation analysis (DFA). HRV was re...

Background: Anthrax is a particularly dangerous infectious disease that affects humans and livestock. Efficacious vaccines that can rapidly induce a long-term immune response are required to prevent anthrax infection in humans. Domains 4 and 1 of the protective antigen (PA) and lethal factor (LF), respectively, have very high antigenic properties. Aims: In this...

1. To assess the effects of acute exposure to high altitude on baroreceptor function in man we evaluated the effects of baroreceptor activation on R-R interval and blood pressure control at high altitude. We measured the low-frequency (LF) and high-frequency (HF) components in R-R, non-invasive blood pressure and skin blood flow, and the effect of baroreceptor modulation by 0. 1-Hz sinusoidal n...
