The natural flavonoids, especially their glycosides, are the most abundant polyphenols in foods and have diverse bioactivities. The biotransformation of flavonoid aglycones into their glycosides is vital in flavonoid biosynthesis. The main biological strategies that have been used to achieve flavonoid glycosylation in the laboratory involve metabolic pathway engineering and microbial biotransformation. In this review, we summarize the existing knowledge on the production and biotransformation of flavonoid glycosides using biotechnology, as well as the impact of glycosylation on flavonoid bioactivity. Uridine diphosphate glycosyltransferases play key roles in decorating flavonoids with sugars. Modern metabolic engineering and proteomic tools have been used in an integrated fashion to generate numerous structurally diverse flavonoid glycosides. In vitro, enzymatic glycosylation tends to preferentially generate flavonoid 3- and 7- O-glucosides; microorganisms typically convert flavonoids into their 7- O-glycosides and will produce 3- O-glycosides if supplied with flavonoid substrates having a hydroxyl group at the C-3 position. In general, O-glycosylation reduces flavonoid bioactivity. However, C-glycosylation can enhance some of the benefits of flavonoids on human health, including their antioxidant and anti-diabetic potential. © 2014 Elsevier Inc. Source

Valproic acid (VPA) is an anticonvulsant and mood-stabilizing drug for the long-term treatment. It is established that VPA has number of side effects affecting metabolic and endocrine system, like weight gain, hyperinsulinemia, changes in sex hormones, dyslipidemia, hyperleptinemia and etc. But the data are not sufficient to judge if VPA treatment can induce metabolic syndrome. Our aim was to investigate metabolic syndrome frequency in VPA-treated (n=11) and CBZ-treated (n=13) patients with epilepsy and in drug-free healthy subjects (n=11). We diagnosed metabolic syndrome according to Adult Treatment Panel III criteria (ATP III). We took blood samples for analysing triglyceride, HDL cholesterol and fasting glucose. Waist circumference and blood pressure was measured as well. Our data revealed that metabolic syndrome is relatively frequent in VPA-treated patients group (45,5%) compared with CBZ group and controls (15.4% and 27.3% respectively) (p<0,5). BMI did not differ between study groups. According to our preliminary data VPA monotherapy increases the risk of metabolic syndrome in patients with epilepsy, but BMI did not differ between VPA monotherapy study group, CBZ monotherapy study group and controls.

Gemination and fusion are anomalies in size, shape and structure of teeth. Gemination more frequently affects the primary teeth, but it may occur in permanent dentitions, usually in the incisor region. Geminated teeth are typically disfigured in appearance due to irregularities of the enamel. Fused teeth can have separated pulpal space, one pulp chamber and two canals or take the form of a large bifid crown with one pulpal space. It is hard to differentiate between fusion and gemination, especially if the supernumerary tooth bud is fused with the adjacent one. Usually, fusion may be differentiated from germination by a reduced number of teeth. An exception is in the unusual case in which the fusion is between a supernumerary tooth and normal tooth. A 20-year-old male referred to us at - "UniDent" - Dental Clinic, Training and Research Center. The patient complained about the large, unusual maxillary central incisors, lip irritation and aesthetic problems. According clinical examination and radiological findings, clinical diagnose was - bilateral germination of central incisors. Several treatment methods have been described in the literature with respect to the different types and morphological variations of fused and geminated teeth, including endodontic, direct\indirect restorative, surgical, periodontal and/or orthodontic treatment. Our patient has demanded for better aesthetics and he choose the treatment option to make two separate PFM crowns. In the beginning of treatment, the length of tooth 11 was 9.5mm, after prosthodontic treatment it has become 11.5mm. For tooth 21, it was 9.9 millimeter and became - 10.8 mm, while the primary width of right central incisor appeared 13.2 millimeter and was narrowed until 10.8 mm. 12.8 mm was the - width of left central incisor, which finally became - 10.4 mm. Despite the considerable number of cases reported in the literature, the differential diagnosis between these abnormalities is very difficult, as well as, to find guideline of proper outcome of treatment therapy of abovementioned abnormalities. That's why, the aesthetic rehabilitation of doubled teeth, has been suggested, to depend upon the patient's desires, but at the same time, avoid treatment plans with aggressive management. Source

Some studies have reported that depression is associated with higher levels of C-reactive protein (CRP) a marker of systemic inflammation that has been shown consistently to predict coronary heart disease risk. The aim of our study was to investigate the association between history of depressive episode and anxiety and presence of low-grade systemic inflammation as measured by serum CRP in postoperative period of coronary angioplasty and aorto-coronary bypass graft surgery. The research was performed in 80 patients (n = 80), mean age 60 ± 15 years. These patients have no high cholesterol level, high body mass index and n = 64 (80%) of them are no smoker. To evaluate depression we used Beck depression scale. Anxiety was assessed by the Spilberger State-trait anxiety scale. CRP was measured in venous blood. Results show that increased level of C-reactive protein was found in aorto-coronary bypass graft surgery group n = 28 (70%), in angioplasty group C-reactive protein n = 12 (30%); χ2 = 6.40 p = 0.012. In angioplasty group patients who had increased level of CRP had high degree of depression p = 0.001. In these group was revealed high degree of trait anxiety p < 0.001 too. In aorto-coronary bypass surgery group elevated level of CRP was associated with high degree of depression p = 0.001. Our study demonstrated association between depression, anxiety and increased C-reactive protein level. Inflammation, the key regulator of CRP synthesis, plays a pivotal role in atherothrombotic cardiovascular disease. Our findings have important implications for explaining the pathophysiological mechanisms of cardiovascular disease. Source

Present research aimed at investigation of the role of several inflammatory cytokines and free toxic radicals in Multiple Sclerosis (MS) course and disability progression as well as factors that can assist to the early transition of Relapse Remitting MS (RRMS) in Secondary Progressive MS (SPMS). Totally 22 MS patients, 14 RRMS and 8 SMPS have been investigated. Age at disease onset, disease duration, number of relapses and the Kurtzke Expanded Disability Status Scale (EDSS) scores were collected. Control comprised 10 healthy volunteers matched for age and sex. Brain was visualized by Magnetic Resonance Tomography (MRT- Siemens AVANTO-1.5-Tesla). Blood pro-inflammatory cytokines were detected by Enzyme Linked immunosorbent Assay (ELISA). Blood free toxic radicals and antioxidant enzymes were detected by Electron Paramagnetic Resonance Method (EPR). Statistics was performed using the SPSS-11.0. Blood pro- and anti-inflammatory factors (γ-Interferon, IL-6, IL-10) were elevated in MS patients against control. Increased blood IL-6 and IL-10 found in RRMS as compared to SPMS, while γ-interferon was higher in SPMS (p<0.000). Blood EPR specters of Lypoperoxiradical (LOO-) and superoxide anion (O2-) were increased in SPMS patients compared to RRMS and control. Blood EPR specters of antioxidant enzymes: superoxidismutase (SOD), catalase (CAT) and Glutathione reductase (GR) found elevated in RRMS against SPMS and control. Positive correlation was found between γ-interferon and EDSS (r=+0.52 p<0.05) in SPMS and negative correlation established between SOD and CAT and EDSS (r=-0.84 and r=-0.60 respectively, p<0.05) in RRMS. Multiple logistic regression toward the brain MRI Injury volume proved significance of C reactive protein, γ-interferon and CAT. Present research suggested that the state of endogenous protection system and blood content of antioxidant enzymes (CAT, SOD) in MS patients could play a significant role for early progression of RRMS in SPMS.
