Influence of Bacillus subtilis on the growth of calcium oxalate
Authors: Chen Long , Xie Anjian , Jia Rong , Shen Yuhua , Tang Wenzhong , Li Chuanhao 
Published: June 2007

AbstractThe influence of the bacteria Bacillus subtilis (B. subtilis) on the nucleation, growth and aggregation of calcium oxalate (CaOx) crystals in aqueous solution has been studied. The crystals obtained were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and X‐ray powder diffractometry. The results show that, in the presence of B. subtilis, quasi‐hexagonal calcium oxalate monohydrate (COM) crystals are obtained after 24 hours of reaction at a temperature of 30°C ± 1K. However, without the presence of the bacteria, irregular CaOx crystals were obtained which contain two crystal phases: COM and calcium oxalate dihydrate (COD). This suggests that B. subtilis may promote the crystallization of COM, the major component of urinary stone. The formation mechanism of CaOx crystals in the presence of B. subtilis is explored, indicating that the cell walls and extracellular proteins of the bacteria may act as templates to induce the nucleation, growth and aggregation of CaOx crystals.

Different and similar at the same time: when the activation of dissimilarity makes people look more similar
Authors: Ruys Kirsten I. , Spears Russell , Gordijn Ernestine H. 
Published: June 2007

AbstractWhether two people are presented as similar or different may have a strong impact on the outcome of their comparison. In the present research, we examined the counterintuitive hypothesis that activating dissimilarity increases the perception of similarities between people, in other words increases perceived feature overlap, during the comparison process. We investigated this prediction by asking people to judge the perceived similarity between two faces with a suboptimally related or unrelated morph inserted in between (to influence joint categorization), and with similar or different facial expressions (to vary the salience of similar or different features). The results confirmed our expectations: In the similarity (joint categorization) condition, two faces that differed in expression were perceived as more dissimilar than faces with the same expression. More important for our prediction, in the dissimilarity condition two faces with different expressions were no longer perceived as more dissimilar than two faces with the same expression. We discuss implications of these findings for the mechanisms underlying comparisons between people. Copyright © 2007 John Wiley & Sons, Ltd.
Quarterly GPPA earnings data: Time‐series properties and predictive ability results in the airlines industry
Authors: Hillison W. A. , Hopwood W. S. , Lorek K. S. 
Published: July 2007

AbstractThis paper provides preliminary results regarding the impact of general purchasing power adjustments (GPPA) on quarterly earnings for 24 firms from the airlines industry. Findings indicated that GPPA transformations do not substantially alter the time‐series properties of quarterly earnings data. Two Box‐Jenkins models, (100) × (100) and (100) × (110) were identified as possible parsimonious models for the airlines industry. It is recommended that these structures be considered as viable candidates for earnings expectations models in market studies testing for informational content of GPPA earnings. The predictive findings demonstrated that predictions of historical cost quarterly earnings were significantly more accurate than GPPA predictions for four of the five horizons tested.
Protective effects of isothiocyanates alone or in combination with vitamin C towards N‐nitrosodibutylamine or N‐nitrosopiperidine‐induced oxidative DNA damage in the single‐cell gel electrophoresis (SCGE)/HepG2 assay
Authors: García Almudena , Haza Ana I. , Arranz Nuria , Rafter Joseph , Morales Paloma 
Published: June 2007

AbstractThe aim of this study was to investigate the protective effect of isothiocyanates alone or in combination with vitamin C towards N‐nitrosodibutylamine (NDBA) or N‐nitrosopiperidine (NPIP)‐induced oxidative DNA damage in the single cell gel electrophoresis (SCGE)/HepG2 assay. Phenethyl isothiocyanate (PEITC) and indole‐3‐carbinol (I3C) alone showed a weak protective effect towards NDBA (0.1 µm, 26–27%, respectively) or NPIP (1 µm, 26–28%, respectively)‐induced oxidative DNA damage. Allyl isothiocyanate (AITC) alone did not attenuate the genotoxic effect provoked by NDBA or NPIP. In contrast, HepG2 cells simultaneously treated with PEITC, I3C and AITC in combination with vitamin C showed a stronger inhibition of oxidative DNA‐damage induced by NDBA (0.1 µm, 67%, 42%, 32%, respectively) or NPIP (1 µm, 50%, 73%, 63%, respectively) than isothiocyanates (ITCs) alone. One feasible mechanism by which ITCs alone or in combination with vitamin C exert their protective effects towards N‐nitrosamine‐induced oxidative DNA damage could be by the inhibition of their cytochrome P450 dependent bioactivation. PEITC and I3C strongly inhibited the p‐nitrophenol hydroxylation (CYP2E1) activity (0.1 µm, 66–50%, respectively), while the coumarin hydroxylase (CYP2A6) activity was slightly reduced (0.1 µm, 25–37%, respectively). However, the ethoxyresorufin O‐deethylation (CYP1A1) activity was only inhibited by PEITC (1 µm, 55%). The results indicate that PEITC and I3C alone or PEITC, I3C and AITC in combination with vitamin C protects human‐derived cells against the oxidative DNA damaging effects of NDBA and NPIP, two food carcinogenic compounds.

Chronic ethanol intake inhibits in vitro osteogenesis induced by osteoblasts differentiated from stem cells
Authors: Rosa Maria L. , Beloti Marcio M. , Prando Natalia , Queiroz Regina H. C. , Oliveira Paulo T. de , Rosa Adalberto L. 
Published: June 2007

AbstractThe study investigated whether chronic ethanol (ETH) intake and subsequent ETH exposure of cell cultures affects osteoblast differentiation by evaluating key parameters of in vitro osteogenesis. Rats were treated with 5–20% (0.85–3.43 mm) ETH, increasing by 5% per week for a period of 4 weeks (habituation), after which the 20% level was maintained for 15 days (chronic intake). Bone‐marrow stem cells from control (CONT) or ETH‐treated rats were cultured in osteogenic medium which was either supplemented (ETH) or not supplemented (CONT) with 1.3 mm ethanol. Thus, four groups relating to rat treatment/culture supplementation were evaluated: (1) CONT/CONT, (2) ETH/CONT, (3) CONT/ETH and (4) ETH/ETH. Cell morphology, proliferation and viability, total protein content, alkaline phosphatase (ALP) activity and bone‐like nodule formation were evaluated. Chronic ethanol intake significantly reduced both food and liquid consumption and body weight gain. No difference was seen in cell morphology among treatments. Cell number was affected at 7 and 10 days as follows: CONT/CONT = CONT/ETH < ETH/CONT = ETH/ETH. Doubling time between 3 and 10 days was greater in groups of CONT animals: ETH/ETH = ETH/CONT < CONT/ETH = CONT/CONT. Cell viability and ALP activity were not affected by either animal treatment or culture exposure to ethanol. At day 21, the total protein content was affected as follows: ETH/ETH = CONT/ETH < ETH/CONT = CONT/CONT. Bone‐like nodule formation was affected as follows: ETH/ETH < CONT/ETH < ETH/CONT < CONT/CONT. These results show that chronic ethanol intake, followed by the exposure of osteoblasts to ethanol, inhibited the differentiation of osteoblasts, as indicated by an increased proliferation rate and reduced bone‐like nodule formation.

Decentralization and district development planning in Zimbabwe
Authors: Mutizwa‐Mangiza N. D. 
Published: July 2007

AbstractOne of the most important dimensions of rural development policy in Zimbabwe since independence has been rural local government reform, in particular decentralization policy. Evidence from a number of recent studies is used to present a comprehensive review of Zimbabwe's experience of local government decentralization during the first eight years of independence, 1980 to 1988. Section 2 presents a brief outline of some basic concepts on decentralization which have guided the discussion. Section 3 contains a short account of the local government system inherited from the colonial era. Section 4 outlines the major post‐independence reforms, that is: the 1980 District Councils Act; the 1984‐85 Prime Minister's Directive on Decentralization; the 1985 Provincial Councils and Administration Act; and the 1988 Rural District Councils Act. Section 5 presents an assessment of these reforms, paying particular attention to organizational, financial and planning issues. While some important improvements have been achieved in rural Communal Areas‐in particular the extension of services and increases in local revenues and popular participation‐the system of local government and administration remains a dual one. Other problems include the gap between the planning and budgeting processes, continued financial dependence of district councils on central government, and a lack of serious effort by central government to make use of provincial and district development plans.
