Oxidant/antioxidant imbalance has been reported in some infectious diseases, including community-acquired pneumonia (CAP). The aim was to assess the antioxidant status in adults with CAP and its relationship with clinical severity at admission. Fifty-nine patients with CAP were enrolled and categorized at admission by the FINE score, from July 2010 to October 2012. In the same period 61 control...
متن کاملMolecular and cytogenetic characterisation of an unusual case of partial trisomy/partial monosomy 13 mosaicism: 46,XX,r(13)(p11q14)/46,XX,der(13)t(13;13)(q10;q14).
A female infant with multiple malformations and mental retardation was noted to have a rare de novo chromosome abnormality involving mosaicism with two cell lines, one with a ring chromosome 13, and the other with partial trisomy 13 owing to a complex rearrangement. Cytogenetic examination excluded the presence of a t(13q;13q) cell line and showed a cell line with a marker chromosome containing...
متن کاملOptimal Packings of 13 and 46 Unit Squares in a Square
Let s(n) be the side length of the smallest square into which n non-overlapping unit squares can be packed. We show that s(m2 − 3) = m for m = 4, 7, implying that the most efficient packings of 13 and 46 squares are the trivial ones. The study of packing unit squares into a square goes back to Erdős and Graham [2], who showed that large numbers of unit squares can be packed in a way that is sur...
متن کامل2,4-Diamino-5-benzylpyrimidines as antibacterial agents. 13. Some alkenyl derivatives with high in vitro activity against anaerobic organisms.
A series of 2,4-diamino-5-(3,5-dialkenyl-4-methoxy- or -4-hydroxybenzyl)pyrimidines was prepared from [(allyloxy)benzyl]pyrimidines by Claisen rearrangements, and the resulting allyl phenols were further modified by methylation and rearrangement to 1-propenyl analogues. Analogous 3,4-dimethoxy-5-alkenyl derivatives were prepared by similar techniques. High in vitro antibacterial activity was ob...
متن کامل1,5-Diamino-2,6-dibromo-9,10-anthraquinone
In the title compound, C(14)H(8)Br(2)N(2)O(2), the mol-ecular structure features intra-molecular N-H⋯O [2.639 (2) Å and 130°] and N-H⋯Br [3.053 (2) Å and 114°] hydrogen bonding. Due to inversion symmetry, the asymmetric part of the unit cell consits of one half-mol-ecule. In the crystal, inversion dimers linked by pairs of N-H⋯O [2.955 (2) Å and 135°] hydrogen bonds occur. The structure also fe...
