BACKGROUND Recent cross-sectional studies indicate that obesity is a risk factor for periodontal disease. Exercise training in high fat mice or rats can inhibit gingival inflammation effectively. The objective of this human intervention study was to investigate whether short-term weight control could affect periodontal indexes and serum and gingival crevicular fluid (GCF) biomarkers in young Ko...

An impressively simple and precise spectrofluorimetric procedure was established and validated for ponatinib (PTB) quantitation in biological fluids such as human plasma and human urine. This method depends on examining the fluorescence characteristics of PTB in a micellar system of Cremophor RH 40 (Cr RH 40). Cr RH 40 enhanced the intrinsic fluorescence of PTB distinctly in aqueous water. The ...

The aim of the work was to investigate effect intense physical activity on testosterone, cortisol and insulin blood concentration in elite athletes. study conducted with participation 26 athletes endurance events. This assessed resting hormones before exercise acute response after intensive loads. influence loads different direction (strength speed vs incremental load VO2 max achievement) inves...

the present research was performed to investigate the effects of aerobic dance with different durations on salivary cortisol and testosterone,and consequently on the mood and body mass of inactive young women. the design of the research was quasi–experimental and the sample consisted of 19 inactive young women (mean age: 30+3 years, height: 167+5.1 cm, weight: 65.5+7.4) who were randomly divide...

In a one-year follow-up study, 444 blood histamine determinations were performed in 163 patients with solid malignant tumours. Compared with normal subjects, blood histamine levels were significantly lower in patients with unresected primary tumours (30.7 + 19.9 ngml -), metastases (34.1 + 17.1 ngml -), or both (24.5+12.8ngml-1). By contrast, after successful tumour resection, histamine blood l...

Salmeterol is a long-acting beta2-agonist, which is on the WADA prohibited list, but can be used by athletes in therapeutic doses by inhalation. The prohibited list, however, contains no urinary threshold for salmeterol, which gives athletes the opportunity to inhale unlimited doses of salmeterol. In doping controls, metabolites may be used as markers for misuse of substances. No studies have d...

Levoglucosan is a unique marker for biomass burning that can be transported in the atmosphere and preserved in archives such as ice cores. A new method to determine the concentrations of levoglucosan in Tibetan ice-core samples using high-performance liquid chromatography with electrospray ionization mass spectrometry (HPLC-ESI/MS) was developed. Levoglucosan was separated from coeluting water-...

HS0507+0434 and HS 2240+1234 are two new common proper motion pairs of DA white dwarfs, discovered by the Hamburg Quasar Survey. Our model atmosphere analysis shows that HS 0507+0434A has an effective temperature of 20000K and is remarkably young (τcool <1Gyr) compared to the average cooling time of all known wide double degenerates (≈ 3Gyr). The cooler B component of HS 0507+0434 is particular...

CONTEXT It is not yet clear whether the diurnal variation in testosterone is regulated by circadian or homeostatic (sleep) influences. OBJECTIVE The present study tested whether testosterone is driven by a circadian-independent sleep effect by shifting sleep acutely to daytime in a 24-h sampling regiment. DESIGN, SETTING, AND PARTICIPANTS In the sleep laboratory, seven healthy young men (ag...
