AIM CDKN2A/2B near chromosome 9p21 has been proposed as a potential genetic etiology for both atherosclerosis and arterial calcification. DNA methylation, which can change the expression of CDKN2A/2B, may be an underlying mechanism for this association. This study aimed to evaluate whether CDKN2A/2B methylation is related to aortic arch calcification (AAC) in patients with ischemic stroke. ME...

INTRODUCTION At the time of the study, 3 plasmid-borne qnr determinants (qnrA, qnrB and qnrS) and 1 plasmid-borne aminoglycoside-modifying enzyme determinant that confers quinolone resistance (aac(6')-Ib-cr) had been described in the literature. MATERIALS AND METHODS We studied the prevalence of the 3 qnr determinants in a total of 117 nalidixic acid-resistant urinary isolates of Klebsiella p...

Background: Municipal solid waste incineration (MSWI) bottom ash contains a not insignificant amount of metallic aluminum, while circulating fluidized bed combustion (CFBC) fly ash is rich in active SiO 2. To reduce the materials cost of autoclaved aerated concrete (AAC) production, these two types of solid waste could theoretically be used as the aerating agent and silica source, respectively....

The ADP/ATP Carrier (AAC) is the most abundant transporter of the mitochondrial inner membrane. The central role that this transporter plays in cellular energy production highlights the importance of understanding its structure, function, and the basis of its pathologies. As a means of preparing proteoliposomes for the study of membrane proteins, several groups have explored the use of cell-fre...

Augmentative and Alternative Communication (AAC) systems are communication aids for people who cannot speak because of motor or cognitive impairments. We are developing AAC systems where users select information they wish to communicate, and this is expressed using an NLG system. We believe this model will work well in contexts where AAC users wish to go beyond simply making requests or answeri...

One hundred fifty AAC(6')-Ib-positive gram-negative isolates collected between 1981 and 1991 were examined by PCR for the presence of the aac(6')-Ib-cr variant and other plasmid-mediated quinolone resistance (PMQR) genes. None had the aac(6')-Ib-cr variant, qnrA, qnrS, qnrC, or qepA, but two strains collected in 1988 had qnrB alleles, making these the earliest known PMQR genes.

Objective: Fluoroquinolones are the commonly prescribed antimicrobial for Gram-negative and Gram-positive microorganisms. The resistance against these antibiotics is of importance in therapy. The current study aimed at determination of aac(6’)-Ib-cr gene within the Enterobacterial isolates and their transmission dynamics. Materials and Methods: Ninety-seven isolates of Enterobacteriaceae collec...

Avian tumour virus-infected chick embryo fibroblasts express new antigens, identical with the viral envelope antigens, in their plasma membranes. Electron-microscopic examination of carbon-platinum replicas of cells labelled with haemocyanin-marked antibody has shown the distribution of these antigens to be diffuse over the cell surface with an increased concentration on peripheral cell process...

Poly (N-isopropylacrylamide) (pNIPAm) is one of the most completely studied “smart” polymers due to its unique reversible thermoresponsivity.That is, when pNIPAm in water is heated > ~31°C, it transits from a random coil to a globule conformation; this transition is reversed when T < ~31°C. This conformational change is accompanied by water exchange process. When pNIPAm undergoes the coil to gl...

The purpose of this study is to examine caregivers’ attitudes toward augmentative and alternative communication (AAC) used by adults with mental retardation. Specifically, the study investigated the amount of training the caregivers received about their clients’ AAC intervention plans and the caregivers’ self-efficacy to facilitate communication from their clients. The survey was administered t...
