OBJECTIVE: The purpose of the study was to evaluate the incidence of acute-onset (within 6 weeks after surgery) postoperative endophthalmitis and to assess the visual acuity outcomes after treatment over a 10-year period at one institution.

    PATIENTS AND METHODS: This retrospective study reviews all surgical cases performed between January 1, 1984 and December 30, 1994 at the Anne Bates Leach Eye Hospital, Bascom Palmer Eye Institute, University of Miami Medical Center, for the occurrence of nosocomial acute-onset postoperative endophthalmitis.

    RESULTS: The overall 10-year incidence of acute-onset postoperative endophthalmitis after intraocular surgery was 0.093% (54/58, 123). The incidences of culture-proven acute-onset postoperative endophthalmitis by surgical category were as follows: cataract surgery with or without intraocular lens (IOL) (0.082%, 34/41, 654), pars plana vitrectomy (PPV) (0.046%, 3/6557), penetrating keratoplasty (0.178%, 5/2805), secondary IOL placement (0.366%, 5/1367), glaucoma surgeries (0.124%, 4/3233), combined trabeculectomy and cataract surgery (0.114%, 2/1743), and combined penetrating keratoplasty and cataract surgery (0.194%, 1/515). The median visual acuity after endophthalmitis treatment was 20/200. The median visual acuities after endophthalmitis treatment by procedure were as follows: cataract surgery with or without IOL (20/133), PPV (no light perception), penetrating keratoplasty (2/200), secondary IOL implantation (20/40), glaucoma surgery (20/80), and combined trabeculectomy and cataract surgery with or without IOL (20/150).

    CONCLUSIONS: The overall incidence of endophthalmitis after intraocular surgery was 0.093%. The incidence of endophthalmitis was higher after secondary IOL implantation than after cataract extraction (P = 0.008, Fisher's exact test). After treatment, the visual acuity outcomes were worse in the patients who developed endophthalmitis after PPV than after cataract extraction, glaucoma procedures, or secondary IOL implantation (P < 0.05, analysis of variance, Duncan's multiple range test). Acuity outcomes after treatment of endophthalmitis were better among the patients with secondary IOL implantation than after penetrating keratoplasty or PPV (P < 0.05, analysis of variance, Duncan's multiple range test). The results of this 10-year review from a large teaching center may serve as a source of comparison for other centers and future studies.

Free-standing nanostructures such as suspended carbon nanotubes, graphene layers, III-V nanorod photonic crystals and three-dimensional structures have recently attracted attention because they could form the basis of devices with unique electronic, optoelectronic and electromechanical characteristics. Here we report the growth by molecular beam epitaxy of free-standing nanoplates of InAs that are close to being atomically plane. The structural and transport properties of these semiconducting nanoplates have been examined with scanning electron microscopy, transmission electron microscopy, X-ray diffraction and low-temperature electron transport measurements. The carrier density of the nanoplates can be reduced to zero by applying a voltage to a nearby gate electrode, creating a new type of suspended quantum well that can be used to explore low-dimensional electron transport. The electronic and optical properties of such systems also make them potentially attractive for photovoltaic and sensing applications.

Twenty six arsenic (As) resistant bacterial strains were isolated from As contaminated paddy soil of West Bengal, India. Among them, 10 isolates exhibited higher As resistance capacity and could grow in concentration of 12000 mg l­1 of arsenate (AsV) and 2000 mg l­1 of arsenite (AsIII) in growing medium. Maximum growth was observed at 1000 mg l­1 and 100 mg l­1 in case of AsV and AsIII respectively. Results of incubation study carried out in basal salt minimal media (BSMY) containing 25 mg l­1 of AsV and AsIII separately showed that the isolates could accumulate 1.03 ­ 6.41 mg L­1 of AsV and 2.0 ­ 7.6 mg l­1 of AsIII from the media. The bacterial isolate AGH­21 showed highest As accumulating capacity both for AsV (25.64%) and AsIII (30.4%) under laboratory conditions. The isolates AGH­21 (NCBI accession no: HQ834295) showed highest sequence similarity (98%) with Bacillus sp. and could be used as a potential bioremediator in future to combat with arsenic toxicity.

Click to expand choices. The transmembrane topology of the Acr3 family arsenite transporter Acr3 from Bacillus subtilis was analysed experimentally using translational fusions with alkaline phosphatase and green fluorescent protein and in silico by topology modelling. Initial topology prediction resulted in two models with 9 and 10 TM helices respectively. 32 fusion constructs were made between truncated forms of acr3 and the reporter genes at 17 different sites throughout the acr3 sequence to discriminate between these models. Nine strong reporter protein signals provided information about the majority of the locations of the cytoplasmic and extracellular loops of Acr3 and showed that both the N- and the C-termini are located in the cytoplasm. Two ambiguous data points indicated the possibility of an alternative 8 helix topology. This possibility was investigated using another 10 fusion variants, but no experimental support for the 8 TM topology was obtained. We therefore conclude that Acr3 has 10 transmembrane helices. Overall, the loops which connect the membrane spanning segments are short, with cytoplasmic loops being somewhat longer than the extracellular loops. The study provides the first ever experimentally derived structural information on a protein of the Acr3 family which constitutes one of the largest classes of arsenite transporters.

Aneuploidy plays a significant role in adverse human health conditions including birth defects, pregnancy wastage and cancer. Although there is clear evidence of chemically induced aneuploidy in experimental systems, to date there are insufficient data to determine with certainty if chemically induced aneuploidy contributes to human disease. However, since there is no reason to assume that chemically induced aneuploidy will not occur in human beings, it is prudent to address the aneugenic potential of chemicals in the safety assessment process. A wide range of methods has been described for the detection of chemically induced aneuploidy including subcellular systems, tests with fungi, plants and Drosophila as well as in vitro mammalian systems and in vivo mammalian somatic and germ cell assays. However, none of these methods is sufficiently validated or widely used in routine screening. Underlying the efforts to develop aneuploidy-specific assays is the presumption that current genetic toxicology tests do not detected chemicals that have aneuploidy-inducing potential. To address this, we have critically evaluated data from standard genetic toxicology assays for 16 known or suspected aneugens. The conclusions from the review are listed below. 1. At present there are only nine chemicals that can be classified as definitive aneugens, as determined by positive results in in vivo rodent assays. 2. As expected, the majority of definitive and suspected aneugens are negative in the bacterial mutation assay. 3. The majority of definitive aneugens evaluated induce polyploidy in vitro. With few exception, they also induced structural chromosome aberrations in vitro. 4. All of the definitive aneugens that have been sufficiently tested induce micronuclei in rodent bone marrow cells in vivo. A number of these chemicals also induced structural chromosome aberrations in vivo. 5. There is no evidence for a unique germ cell aneugen, that is a chemical that induces aneuploidy in germ cells and not in somatic cells. Furthermore, an analysis of several databases indicates the proportion of chemicals which induce polyploidy and not chromosome aberrations in vitro is low. Based on these conclusions, the following recommendations are made: for screening purposes, a standard genotoxicity test battery (including an in vitro cytogenetic assay with an assessment of polyploidy and clastogenicity at the same harvest time) should be performed; in the absence of polyploidy induction in vitro no further evaluation of aneuploidy-inducing potential is needed; if polyploidy is observed, in vitro follow-up testing to investigate further the aneuploidy-inducing potential should be conducted; such follow-up testing will generally start with the conduct of a standard in vivo somatic cell micronucleus assay; if the in vivo somatic cell micronucleus assay is negative, with adequate evidence of exposure of the bone marrow to the test compound, no further testing of aneuploidy-inducing potential is needed; if the in vivo somatic cell micronucleus assay is positive, further information on mechanisms of micronucleus induction can be obtained by using kinetochore/centromeric staining in vitro and/or in vivo; an assessment of potential germ cell aneuploidy activity may then be considered; aneuploidy induction which does not involve the direct interaction of a chemical or its metabolite(s) with DNA is expected to have a threshold. This must be considered in the risk assessment of such chemicals; this is not addressed by current risk assessment guidelines.

A survey is given of the use of chelating agents in the treatment of metal poisonings. 1 The complexing agents in established clinical use are the polyaminopolycarboxylic acid EDTA (ethylenediamine tetraacetate) and the thiols BAL (2, 3-dimercaptopropanol) and D-penicillamine. Desferrioxamine is useful in the treatment of iron overloading. 2 The theoretical foundation of the metal-ligand interaction and some general principles of value in the search for new metal antidotes are outlined. 3 Recent research has shown that 2, 3-dimercaptosuccinic acid (DMS) and 2, 3-dimercaptopropane-1-sulphonate (DMPS) are effective in mercury and arsenic poisonings. 4 DMS and DMPS are of significantly lower toxicity than BAL, and they can be administered orally or intravenously. 5 A particularly low toxicity of DMS is reported from clinical and experimental studies, and this agent may be useful against several metal poisonings including mercury, lead and gold.
