This study aimed to investigate the effect of spermine (Spm) as a chemical chaperone and glycation inhibitor on the lipid profile and HDL functionality in the short- and long-term treatment of the STZ-induced diabetic rats. Male Wistar rats were divided into 4 groups (control, n=7; diabetic, n=9). Two groups (named 2 and 3) were injected intraperitoneally(More)
PURPOSE To carry out a preliminary study examining the efficacy of long-term hot-tub therapy (HTT) in the improvement of diabetic complications on streptozotocin-induced diabetic rats. MATERIALS AND METHODS Male Wistar rats were immersed mid-sternum in a circulating water bath (42 degrees C for 30 min) to obtain a core body temperature of 41 degrees C;(More)
BACKGROUND L-Lysine (L-Lys) has been known as an inhibitor of protein glycation; however, its long-term use for diabetes treatment considering different aspects of diabetic complication is not seen in the literature. In addition, the effect of L-Lys, as a chemical chaperone, was considered on protein folding and activity. METHODS The(More)
Diabetes mellitus has been classified as a conformational disease because of changes induced in the structure and function of proteins due to hyperglycemia. In this study, we investigated the effect of high-dose and long-term use of acetyl salicylic acid (ASA) on the streptozotocin-induced diabetic rats as a model of type I diabetes, with consideration on(More)
Crocin and crocetin are two important natural saffron carotenoids, which, along with dimethylcrocetin (DMC) as a semi-synthetic product, are responsible for its color. Many biological properties of saffron have been reported, among which the anticancer property is the most important. Some anticancer drugs have direct interaction with DNA, and thus the(More)
We investigated the interaction of meso-tetrakis (N-para-methylanilium) porphyrin (TMAP) in its free base and Fe(II) form (Fe(TMAP)OAc) as a new derivative, with high molecular weight DNA at different ionic strengths, using various spectroscopic methods and microcalorimetry. The data obtained by spectrophotometery, circular dichroism (CD), fluorescence(More)
Among different biological effects of acetylsalicylic acid (ASA), its anticancer property is controversial. Since ASA hydrolyzes rapidly to salicylic acid (SA), especially in the blood, interaction of both ASA and SA (as the small molecules) with ctDNA, oligo(dA·dT)15 and oligo(dG·dC)15, as a possible mechanism of their action, is investigated here. The(More)
Saffron (Crocus sativus L.) has been an important subject of interest for research teams in the past two decades because of its various biological properties. Chemical analysis has shown the presence of more than 150 components in saffron stigmas. Here, we review the medicinal and industrial applications of saffron. Then, the new findings from different(More)
The interaction of 8-methoxypsoralen (8-MOP) with calf thymus DNA was studied in darkness at 25 degrees C and pH 7.4. The enthalpy curve for 8-MOP-DNA interaction was obtained by isothermal titration calorimetry and showed a two-step process for the interaction. According to the spectrophotometric data, it was suggested that some compaction may occur in the(More)
The interaction of dodecyl trimethylammonium bromide (DTAB), a cationic surfactant, with calf thymus DNA has been studied by various methods, including potentiometric technique using DTAB-selective plastic membrane electrode at 27 and 37 degreesC, isothermal titration microcalorimetry and UV spectrophotometry at 27 degreesC using 0.05 M Tris buffer and 0.01(More)
