    • resumo “fórmula de nanocompósitos com base de ferro para tratamento rápido e eficiente de anemia ferropriva”. trata-se de fórmulas de nanopartículas de óxidos de ferro cobertas com uma mistura de multivitaminas tais como ácido fólico, ácido nicotínico (vitamina b9) e ácido ascórbico (vitamina c) foram desenvolvidas para o tratamento rápido e eficiente de anemia ferropriva fatal. uma pequena dose única de nanocompósito multivitamínico de óxidos de ferro de a partir de 25 mg de ferro elemental por dose é suficiente para aumentar o nível de hemoglobina de 4,4 g/dl para até 14,6 g/dl em apenas quatro dias após a administração. a multivitamina que é utilizada neste nanocompósito melhora significativamente a absorção de ferro e eleva a concentração de hemoglobina. duas formas de dosagem de nanocompósitos de ferro foram desenvolvidas, cápsulas de gel e solução aquosa, para administração oral. estudos em animais revelam que introduzir uma única dose de nanocompósitos vitamínicos de óxido de ferro contendo 2,57 mg de ferro elemental por kg de peso corporal de rato (igual a 25 mg em humanos) é suficiente para corrigir o nível de hemoglobina e curar anemia por meio de administração oral. o estudo de toxicidade revela que o ld50 de nosso novo nanocompósito de ferro é de 1425,3 mg/kg de peso corporal de rato, o que significa que o ld50 de nanocompósitos de ferro de tamanho nanométrico em humanos (peso de 60 kg) é de 13.854 mg. assim, a dose única exigida para tratamento rápido de anemia ferropriva é 554 vezes menor que o ld50 em humanos. nenhum sinal de qualquer tipo de toxicidade em estudos hematológicos, bioquímicos ou histopatológicos. além disso, o estudo de histopatologia da medula óssea sugere que os nanocompósitos vitamínicos de óxidos de ferro aumentam o número de precursores de rcb que estimulam a medula óssea a produzir mais hemácias.

    • New formulas of Iron oxides nanoparticles capped with a mixture of multivitamins such as folic acid, Nicotinic acid (vitamin B9) and Ascorbic acid (vitamin C) has been developed for the rapid and efficient treatment of life threatening iron-deficiency anemia. Small single dose of iron oxides-multivitamin nano-composite as low as 25 mg elemental iron per does is sufficient to increase the hemoglobin level from 4.4 g/dl up to 14.6 g/dl within only four days after administration. The multivitamin which used in this nano-composite enhances iron absorption significantly and elevated the concentration of hemoglobin. Two dosage forms of Iron nano-composites have been developed, gel capsules and aqueous solution for oral administration. Animal trials studies reveal that introducing single dose of Iron Oxide- vitamin nano-composites containing 2.57 mg elemental iron per kg rat body weight (equal to 25 mg in human) is sufficient to correct the hemoglobin level and cure Anemia via oral administration. The toxicity study reveals that the LD50 of our new iron nano-composite is 1425.3 mg/kg rat body weight, means that the LD50 of nano-sized iron nano-composites in standard human (60 kg weight) is 13,854 mg. Thus, the single dose required for rapid treatment of iron deficiency anemia is 554 times less than the LD50 in human. No apparent of any sight of toxicity on hematological, biochemistry or histopathology studies. Moreover, the histopathology study of the bone-marrow suggests that the used iron oxides -vitamin nano-composites increase the number of the RBCs precursors which stimulate the bone- marrow to produce more RBCS.
    • 已经开发了用多种维生素如叶酸,烟酸(维生素B9)和抗坏血酸(维生素C)混合物覆盖的铁氧化物纳米颗粒的新配方,用于快速有效地治疗危及生命的缺铁性贫血。 小单次剂量的铁氧化物 - 多种维生素纳米复合材料低至25mg元素铁足以在给药后仅4天内将血红蛋白水平从4.4g / dl升至14.6g / dl。 在纳米复合材料中使用的多种维生素显着增强了铁的吸收,提高了血红蛋白的浓度。 已经开发了两种剂型的铁纳米复合材料,胶囊和口服水溶液。 动物试验研究显示,每kg体重(相当于人体25mg)含有2.57mg元素铁的单剂量氧化铁 - 维生素纳米复合物足以校正血红蛋白水平,并通过口服治疗治愈贫血。 毒性研究表明,我们的新型铁纳米复合材料的LD50值为1425.3 mg / kg,体重大小,意味着纳米级铁纳米复合材料在标准人体(60kg重量)中的LD50为13,854mg。 因此,快速治疗缺铁性贫血所需的单剂量比人类LD50低554倍。 对血液学,生物化学或组织病理学研究没有明显的毒性。 此外,骨髓的组织病理学研究表明,使用的氧化铁 - 维生素纳米复合材料增加了刺激骨髓以产生更多RBCS的RBC前体的数量。

    • Real-time calibration of a tunable matching network (242) that matches the dynamic impedance of an antenna (202) in a radio frequency receiver system (240) is disclosed. The tuning algorithm in the radio frequenzy system (240) includes two non-linear equations that may be solved to determine the reflection coefficient of the antenna. The tunable matching network (242) is repeatedly pertubed and the power received by the antenna (202) is measured after each pertubation at the same node (power detector 246) in the matching network (242). The measured power values (222) are used by an optimizer (216) in converging to a solution that provides the reflection coefficient of the antenna. The reflection of the antenna may be used to determine the input impedance of the antenna. The elements of the matching circuit (242) are then adjusted to match the input impedance of the antenna (202). Thus, effects of changes in the environment of the antenna (202) affecting the impedance may be compensated in realtime.
    • 公开了与射频接收机系统(240)中的天线(202)的动态阻抗匹配的可调匹配网络(242)的实时校准。 无线电频率系统(240)中的调谐算法包括可以求解以确定天线反射系数的两个非线性方程。 可调谐匹配网络(242)被重复地支配,并且在匹配网络(242)中的相同节点(功率检测器246)的每个经过之后测量由天线(202)接收的功率。 测量的功率值(222)由优化器(216)用于会聚到提供天线的反射系数的解。 天线的反射可以用于确定天线的输入阻抗。 然后调整匹配电路(242)的元件以匹配天线(202)的输入阻抗。 因此,可以实时地补偿影响阻抗的天线(202)的环境变化的影响。
