  • Allopurinol (1H-pyrazolo[3,4-d]pyrimidin-4-ol) (Fig. 1) is a commonly used drug in the treatment of chronic gout or hyperuricaemia associated with leukaemia, radiotherapy, antineoplastic agents and treatment with diureticsconditions.1 Allopurinol is a structural isomer of hypoxanthine (a naturally occurring purine in the body) and acts to inhibit xanthine oxidase. In the presence of xanthine oxidase, allopurinol will be converted to alloxanthine (Fig. 2), after that the formation of uric acid from xanthine and hypoxanthine will be inhibited....

  • Let N be a nilpotent group normal in a group G. Suppose that G acts transitively upon the points of a nite non-Desarguesian projective plane P. We prove that, if P has square order, then N must act semi-regularly on P. In addition we prove that if a nite non-Desarguesian projective plane P admits more than one nilpotent group which is regular on the points of P then P has non-square order and the automorphism group of P has odd order.

  • A subset M  E(G) of the edge set E(G) of a graph G is called a matching provided that no two edges in M have a vertex in common. A perfect matching M is a matching with the property that each vertex of G is incident with an edge in M. For k a positive integer, a graph G is k-extendable provided that G has a matching of size k and every matching in G of size at most k can be extended to a perfect matching in G.

  • Since publication of the first edition of CRC Desk Reference of Clinical Pharmacology in 1998, dramatic discoveries in molecular medicine, along with rapid concomitant technological advances, have revolutionized the diagnosis and treatment of a broad range of human diseases with new medications. Given the rapid pace of new discovery, genetic- and cell-based therapeutics have now become a common part of the physicians’ armamentarium. A few examples will be given concerning two leading causes of death—cancer and cardiovascular diseases—to illustrate this....

  • 13.Chất ức chế xanthine oxidase Vai trò của XOi Allopurinol là dẫn chất purin, được kê đơn rộng rãi và là lựa chọn đầu tiên trong điều trị giảm urat huyết. Hiệu quả điều trị allopurinol trong mọi trường hợp tăng acid uric. Trong cơ thể allopurinol được chuyển hóa thành oxipurinol (chất tác dụng) có thời gian bán thải (14 - 28 giờ), do đó có thể dùng mỗi ngày một lần.

  • Acid uric thừa, kết tinh ở khớp và dưới da gây nên bệnh gút (gout). Enzym chuyển xanthin, hydroxyxanthin thành acid uric. Allopurinol ức chế enzym xanthin oxidase, làm giảm sự hình thành acid uric nên được xem là thuốc đặc hiệu. Thế nhưng thực ra nó chỉ ngăn ngừa sự bùng phát cơn gút cấp chứ không chữa khỏi bệnh. Allopurinol chỉ dùng khi xét nghiệm thấy mức acid uric trong nước tiểu hay trong máu ở mức báo động.

  • Let T be an in nite regular tree and n a positive integer. Fix two vertices x and y in T . By a walk or a path between x and y we mean any nite sequence of edges that connect x and y in which backtrackings are allowed. There are many formulas in the literature which give the number of walks of length n between x and y, such as recurrence formulas, generating functions, Green functions, and others. Here we consider walks of length n between x and y which at a certain time follow a number of predetermined steps....

  • This work reports on the direct electrochemistry of the Desulfovibrio gigasaldehyde oxidoreductase (DgAOR), a molybdenum enzyme of the xanthine oxidase family that contains three redox-active cofactors: two [2Fe-2S] centers and a molybdopterin cytosine dinucleotide cofactor. The voltammetric behavior of the enzyme was analyzed at gold and carbon (pyrolytic graphite and glassy carbon) elec-trodes. Two different strategies were used: one with the molecules confined to the electrode surface and a second withDgAOR in solution....
