NSPT decreased oxidative stress and the inflammatory status of patients with MetS and chronic periodontitis. Although similar periodontal improvements were achieved in both groups, the decreases in levels of hs-CRP and IL-6 in the MetS group did not reach the levels in the SH group. Based on these results, NSPT could be more effective in the control of systemic inflammation in patients with MetS in the short-term.

The aim of this prospective case-control study was to determine the change in serum maternal ischemia-modified albumin (IMA) during normal pregnancies. A total of 117 pregnant (first trimester (n=24), second trimester (n=34), and third trimester (n=35)) and non-pregnant healthy women (n=23) were included. Maternal serum IMA, Malondialdehyde (MDA), and albumin levels were measured. Compared with non-pregnant women, the cross-sectional mean IMA levels in pregnant women were significantly increased, while the mean serum MDA and albumin levels were significantly decreased throughout pregnancy. Furthermore, a significant negative correlation between serum IMA and albumin levels (r=-0.354, p<0.001) was found, and there was a weak positive correlation between serum albumin and MDA levels (r=0.334, p<0.001). Serum IMA, which has recently been developed as a clinical marker of ongoing myocardial ischemia, appears to be elevated in normal pregnancy. This may be due to the physiologic oxidative stress state of pregnancy.

3-Alkyl(aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones 2a-g reacted with4-diethylaminobenzaldehyde to afford the corresponding 3-alkyl(aryl)-4-(4-diethyl-aminobenzylidenamino)-4,5-dihydro-1H-1,2,4-triazol-5-ones 3a-g. The acetylation reactions of compounds 3a-e were investigated and compounds 4a-e were thus obtained. The new compounds were characterized using IR, 1H-NMR, 13C-NMR, UV and MS spectral data. In addition, the newly synthesized compounds 3a-g were titrated potentiometrically with tetrabutylammonium hydroxide in four non-aqueous solvents such as isopropyl alcohol, tert-butyl alcohol, acetone and N,N-dimethylformamide (DMF), and the half-neutralization potential values and the corresponding pKa values were determined for all cases. Moreover, 3 and 4 type compounds were also screened for their antioxidant activities.

Five novel 3-alkyl-4-phenylacetylamino-4,5-dihydro-1H-1,2,4-triazol-5-ones (2) were synthesized by the reactions of 3-alkyl-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones (1) with phenylacetyl chloride and characterized by elemental analyses and IR, 1 H-NMR, 13 C-NMR and UV spectral data. The newly synthesized compounds 2 were titrated potentiometrically with tetrabutylammonium hydroxide in four non-aqueous solvents such as isopropyl alcohol, tert-butyl alcohol, acetonitrile and N,N-dimethylformamide, and the half-neutralization potential values and the corresponding pK a values were determined for all cases. In addition, these new compounds and five recently reported 3-alkyl-4-(pmethoxybenzoylamino)-4,5-dihydro-1H-1,2,4-triazol-5-ones (3) were screened for their antioxidant activities.
