Zea mays L. is one of the biggest cropping systems among the sustainable development agronomy. Pollen from this crop source is unexplored and apiculture can be a good partner adding value to the product and creating new jobs helping to solve some social issues as unemployment. However, food safety is crucial, thus the aim of this study was to explore the flavonoid/phenolic profiles from Z. mays L. pollen as a fingerprint for this plant identification and also to demonstrate how the method of bee pollen samples （honeybee collected pollen） is applied. For this purpose, several sources ofZ. mays L. pollen were analyzed, including corn hybrids and genetic modified samples collected at the breeding fields. For this work, samples were taken at several years from 2000 to 2012 and collected from different countries and locations, such as Portugal, Mexico and Brazil. Results showed, for the first time, that the fingerprint （flavonoid/phenolic profile） for Z. mays L. pollen does not change over the time of sampling neither with the region of harvesting. The high performance liquid chromatography-diode array detector （HPLC/DAD） fingerprints of phenolic/flavonoid extract from Z. mays remain unchanged for all samples analyzed from different countries, hybrids and/or genetic modified plants. This is also the first study reporting these phenolic compounds not only in pollen collected directly from hybrid plants, but also in Z. mays bee pollen. The described fingerprinting method is easy, fast and accurate for the characterization of Z. mays L. pollen samples and complete microscopic analysis because it is species-specific.

Objective: Metabolic syndrome (Mets) is the leading cause to develop type 2 diabetes worldwide. We examined associations of Mets components early in life, and their use as risk factors of acquiring Mets. Method: We used an international definition of Mets. subjects were categorized into “Healthy”/“Not Healthy”, altered parameters are low HDL-cholesterol, large waist circumference (WC), hypertriacylglycerolemia, hypertension, and hyperglycemia, in 32 combinations (2^5) with two values (altered/not altered). Mets was identified with three or more altered parameters. Results: A total of 3424 students (ages 17 - 24 years) participated in the survey, and 2475 were “Not Healthy” showing at least 1 parameter altered;from them 49.6% showed low blood HDL either alone or combined, 38.2% had altered waist circumference either alone or combined;while 18.1% showed hypertriacylglycero-lemia either alone or combined. Hypertension and hyperglycemia were the lowest in frequency. Conclusion: We propose that the binomium HDL/ Waist Circumference is the main prevalence factor to develop Mets in the asymptomatic young population, followed by hypertriacylglycerolemia which together define Mets;while hypertension and hyperglycemia seem to occur later in Mets.

Aim: The purpose of this study was to understand the mechanism of nicotine mediated addiction and the role of oligoelements in reducing its effect. Methods: Male Wistar rats (weight 80 g) were treated with single and repeated doses of nicotine and/or oligoelements as follows: group 1 (control) NaCl 0.9%;group 2, nicotine (1 mg/kg);group 3, oligoelements (50 μl/rat);and group 4, nicotine (1 mg/kg) + oligoelements (50 μl/rat). All drugs were intraperitoneally administered for 4 days. Blood for the measurement of glucose was obtained from all the animals. samples of the brain regions (cortex, hemispheres and cerebellum + medulla oblongata) of each rat were obtained and used to measure the concentrations of dopamine, GsH levels, and lipid peroxidation (TBARs) using fluorescence and spectrophotometric methods. Results: Glucose level increased in rats treated with nicotine and oligoelements (p sH level decreased in cerebellum/medulla oblongata and hemispheres (p same animals. TBARs levels increased in cerebellum/medulla oblongata and hemispheres of animals treated with nicotine and oligoelements, but decreased in the same regions (p s treated only with oligoelements. The levels of dopamine decreased in cortex and hemispheres, but increased in cerebellum/medulla and oblongata regions of rats treated with both compounds (p sions: Nicotine and oligoelements are associated with increase in the level of glucose, an effect that was more pronounced in the group treated with both drugs. Reduction of oxidative stress and dopamine metabolism may be involved in this effect.

Clobenzorex is an anorexigenic drug that is widely used in Mexicofor the treatment of obesity, since it helps to reduce body weight. This drug is available as immediate release capsules. To improve compliance to treatment, it was developed a new slow release formulation. In order to establish its usefulness, oral pharmacokinetics and weight reduction of slow release and immediate release formulations of clobenzorex in obese patients were compared. sixty patients with a BMI higher than 27 kg/m2 were included in the study. Two groups of 30 patients were formed, one of them received 30 mg immediate release formulation b.i.d. and the other group received one 60 mg slow release formulation once a day, since under this scheme these formulations are prescribed. Blood samples were obtained at selected times during the first day and once weekly during 4 weeks. After the last dose, samples were obtained at selected times during 48 h. Plasma levels were determined by HPLC-Ms/Ms and pharmacokinetic parameters were obtained. Reduction in Cmax due to increased tmax, as well as, increased half-life were observed with the slow release formulation in comparison with immediate release formulation. Although lower plasma levels of clobenzorex were reached with the slow release formulation, reduction of body weight was similar with both products. Based on the results, it was concluded that slow release formulation of clobenzorex is an adequate formulation of clobenzorex, since pharmacokinetics and effects observed are compatible with a once a day administration.

目的:研究CAD/CAM可切削瓷块的半透明性对瓷贴面最终颜色的影响.材料和方法:使用复合树脂材料(Z250,A4,3M EsPE)堆塑一颗右上颌中切牙,进行标准的切端包绕式贴面预备,激光(Bluecam,sirona)扫描预备完毕的树脂模具,通过CAD软件(CEREC 3D)建立瓷贴面的3D模型.采用3种类型(多色型、高透型和低透型)的可切削瓷块(IPs Empress CAD,Vita A1色)制作瓷贴面.切削而成的贴面经过抛光、上釉后,分别采用高透明度和低透明度的树脂水门汀(Panavia F2.0)粘结到树脂模具上.使用一台数字化比色仪器(Easyshade Advance,Vita)测量粘结后贴面切1/3、中1/3和颈1/3的颜色参数,根据目标颜色(A1)计算△E值.结果:瓷贴面粘结后的颜色相比粘结前树脂模具的颜色(A4)变化较大,△E值:8.9~13.7.但是,根据测量出的△E值,相同条件下,瓷块的类型对粘结后最终颜色的影响并不明显,多色型瓷块△E值=10.7±0.1,高透型瓷块△E值=9.7±0.09,低透型瓷块△E值=13.4±0.11.树脂粘结剂的透明性不会影响最终的颜色匹配,因无论使用高透明性还是低透明性的树脂粘结剂,测得的△E值均小于3种瓷块的△E值.多色型瓷贴面切1/3之间(△E=8.9)和低透型瓷贴面颈1/3之间(△E=13.7)的颜色差别最大,其他的差别均不明显(△E<2.5).结论:本研究显示,CAD/CAM瓷贴面的颜色匹配不受瓷块和树脂粘结剂透明性的影响.
