Optimization of α‐amylase production in solid substrate fermentation
Authors: Tanyildizi M. Şaban , Selen Veyis , Özer Dursun 
Published: May 2009

AbstractResponse surface methodology (RSM) was used to optimize the medium components of α‐amylase production using solid substrate fermentation (SSF). Hazelnut cake (HC), peptone, yeast extract (YE), and (NH4)2SO4 were selected as independent variables for optimization. Central composite design (CCD) was used in design experiments and analysis results. This procedure limited the number of actual experiments performed while allowing possible interactions between the independent variables. By using CCD, 30 experiments were performed for determining the interaction of independent variables and optimization of fermentation medium. The P‐value of the coefficient of linear effect of (NH4)2SO4 concentrations, which was obtained as 0.0001 has shown that this parameter has the greatest effect on the production of α‐amylase. Model F‐value (5.62) implies that the model is significant. The highest α‐amylase activity (4895 IU) was measured when the HC, peptone, YE, and (NH4)2SO4 concentrations in the medium were 22.62, 5.20, 1.62, and 6.81 g L−1, respectively.
A numerical study on heat transfer and friction in rectangular channel with inclined perforated baffles
Authors: Putra A.B.K. , Ahn S.W. , Kang H.K. 
Published: May 2009

AbstractA three‐dimensional numerical study on the turbulent flow and heat transfer characteristics in the rectangular channel with different types of baffles is carried out. The inclined baffles have the width of 19.8 cm, the square diamond type hole having one side length of 2.55 cm, and the inclination angle of 5°. Reynolds number is varied between 23 000 and 57 000. The SST k − ω turbulence model is used in the method to predict turbulent flow. The validity of the numerical results is confirmed by measurement. Numerical results show that the flow patterns around the different baffle type are entirely different and it significantly affects the local heat transfer characteristics. The heat transfer and friction factor characteristics are significantly affected by the perforation density of the baffle plate. The present study demonstrates that the battle type II (3 holes) can enhance the greatest heat transfer rates with advantages from the overall efficiency point of view.

Authors: Marreto R.N. , Peixoto M.P.G. , Teixeira C.C.C. , Freitas L.A.P. 
Published: May 2009

AbstractThe aim of this work was to study the behaviour of conventional spouted beds during water evaporation and to analyze the pressure fluctuations at the maximum water evaporative capacity for different bed heights and air flow rates. The results showed that spout pressure drop could not indicate the proximity of maximum evaporative capacity; however this condition is denoted by a minimum in fountain height. The standard deviation and amplitude of the pressure fluctuations also showed a minimum point at the maximum water evaporation capacity. The frequency domain analysis of pressure fluctuations revealed that the dry bed has a dominant frequency varying from 6 to 8.2 Hz and that the peak of dominant frequency tends to disappear with the increase in water feed rate.
Separation of VOCs from N2 using poly(ether block amide) membranes
Authors: Liu Li , Chakma Amit , Feng Xianshe , Lawless Darren 
Published: May 2009

AbstractThis work deals with the separation of volatile organic compounds (VOCs) from nitrogen streams for organic vapour emission control by poly(ether block amide) membranes. As representative air pollutant VOCs, n‐pentane, n‐hexane, cyclohexane, n‐heptane, methanol, ethanol, n‐propanol, n‐butanol, acetone, dimethyl carbonate, and methyl tert‐butyl ether were used in this study. The separation of both binary VOC/N2 and multicomponent VOCs/N2 gas mixtures was carried out, and the membranes exhibited good separation performance. A VOC concentration of more than 90 mol% was achieved at a feed VOC concentration of 5 mol%. It was found that the permeances of the VOCs were mainly dominated by their solubilities in the membrane, whereas the permeance of N2 was affected by the presence of the VOCs. The permeance of N2 in the VOC/N2 mixtures was shown to be higher than pure N2 permeance due to membrane swelling induced by the VOCs dissolved in the membrane. Nevertheless, theVOC/N2 selectivity increased with an increase in the feed VOC concentration. Among the VOCs studied, the membrane showed a higher permeance to alcohol VOCs than paraffin VOCs. The effects of feed VOC concentration, temperature, stage cut, and permeate pressure on the separation performance were investigated.

AbstractBackgroundDrug‐eluting stents (DES) are superior to bare metal stents (BMS) for treating ostial left anterior descending artery (LAD) lesions, but DES is not suitable for all patients in real life practice.HypothesisWe hypothesize that cutting balloon angioplasty (CBA) followed by BMS (CBA + BMS) for treating ostial LAD lesions is an alternative strategy.MethodsIn our study, 101 consecutive patients (51 with DES and 50 with CBA + BMS) with ostial LAD stenting were included for retrospective investigation between November 2003 and May 2005. The target vessel diameter was ≥3.0 mm.ResultsWe compared the DES group with the CBA + BMS group, the rates of restenosis (10.3% versus 17.9%, p = 0.386), target lesion revascularization (TLR) (5.88% versus 10%, p = 0.487) and major adverse cardiac events (MACE) (7.84% versus 12%, p = 0.525) were similar at 6–8 months angiographic follow‐up, but there were higher bleeding events in the DES group (p = 0.033). During a 2‐year clinical follow‐up, no myocardial infarction occurred in the 2 groups, the rates of TLR (7.84% versus 10%, p = 0.741) and MACE (9.8% versus 12%, p = 0.723) were also similar. The MACE‐free survival rate was 90.2% versus 88 % (p = 0.723).ConclusionsThe CBA + BMS combination has a good long‐term clinical effect in the treatment of ostial LAD lesions; it might be an alternative strategy for patients with contraindication for DES implantation, or patients who cannot endure long‐term dual antiplatelet medication, or in elderly patients.

AbstractBackgroundClaims in the medical literature suggest that neck fullness and witnessed neck pulsations are useful in the diagnosis of typical AV nodal reentrant tachycardia (AVNRT).HypothesisNeck fullness and witnessed neck pulsations have a high positive predictive value in the diagnosis of typical AVNRT.MethodsWe performed a cross‐sectional study of consecutive patients with palpitations presenting to a single electrophysiology (EP) laboratory over a 1 year period. Each patient underwent a standard questionnaire regarding neck fullness and/or witnessed neck pulsations during their palpitations. The reference standard for diagnosis was determined by electrocardiogram and invasive EP studies.ResultsComparing typical AVNRT to atrial fibrillation (AF) or atrial flutter (AFL) patients, the proportions with neck fullness and witnessed neck pulsations did not significantly differ: in the best case scenario (using the upper end of the 95% confidence interval (CI), none of the positive or negative predictive values exceeded 79%. After restricting the population to those with supraventricular tachycardia (SVT) other than AF or AFL, neck fullness again exhibited poor test characteristics; however, witnessed neck pulsations exhibited a specificity of 97% (95% CI: 90%–100%) and a positive predictive value of 83% (95% CI: 52%–98%). After adjustment for potential confounders, SVT patients with witnessed neck pulsations had a seven‐fold greater odds of having typical AVNRT, p = 0.029.ConclusionsAlthough neither neck fullness nor witnessed neck pulsations are useful in distinguishing typical AVNRT from AF or AFL, witnessed neck pulsations are specific for the presence of typical AVNRT among those with SVT.

Photooxidation Degradation of Reactive Brilliant Red K‐2BP in Aqueous Solution by Ultraviolet Radiation/Sodium Hypochlorite
Authors: Zeng Qing‐Fu , Fu Jie , Zhou Yang , Shi Yin‐Tao , Zhu Hai‐Liang 
Published: May 2009

AbstractPhotooxidation degradation of Reactive Brilliant Red K‐2BP (K‐2BP) aqueous solution by ultraviolet irradiation/sodium hypochlorite (UV/NaClO) was investigated. The effects of NaClO dosage, pH, temperature and initial dye concentrations were studied. A possible degradation pathway of K‐2BP was investigated. Acidic or neutral conditions were beneficial to the decolorization of K‐2BP aqueous solution. However, alkaline conditions facilitated chemical oxygen demand (COD) removal. Increasing the solution temperature from 20 to 50°C increased the removal of color and COD. However, at 60°C, the final percentage color and COD removal decreased by approximately 17 and 10%, respectively. Based on the products indentified and theoretical analysis, N=N cleavage and C‐N cleavage were possible initial steps in the degradation of K‐2BP. From the results of this work, we conclude that treatment of UV/NaClO is an efficient method to degrade K‐2BP in aqueous solution.
Cytoskeletal pathologies of Alzheimer disease
Authors: Bamburg James R. , Bloom George S. 
Published: May 2009

AbstractThe histopathological hallmarks of Alzheimer disease are the extracellular amyloid plaques, composed principally of the amyloid beta peptide, and the intracellular neurofibrillary tangles, composed of paired helical filaments of the microtubule‐associated protein, tau. Other histopathological structures involving actin and the actin‐binding protein, cofilin, have more recently been recognized. Here we review new findings about these cytoskeletal pathologies, and, emphasize how plaques, tangles, the actin‐containing inclusions and their respective building blocks may contribute to Alzheimer pathogenesis and the primary behavioral symptoms of the disease.

Cover Picture: Mechanistic Insights into Cyclooxygenase Irreversible Inactivation by Aspirin (ChemMedChem 6/2009)
Authors: Tosco Paolo , Lazzarato Loretta 
Published: May 2009

AbstractThe cover picture shows aspirin docked in the active site of ovine COX‐1. According to the results of this QM/MM study, this is the conformation likely to trigger Ser 530 acetylation under general base catalysis by the carboxylate group of aspirin. The hydroxy group of Tyr 385 proved to play a key role in orienting and polarizing the acetyl moiety, as previously postulated by Hochgesang et al. on the basis of site‐directed mutagenesis experiments.

Mucinous gastric carcinomas
Authors: Choi Jong Sun , Kim Min A , Lee Hee Eun , Lee Hye Seung , Kim Woo Ho 
Published: May 2009

AbstractBACKGROUND:Mucinous gastric carcinoma (MGC) is characterized by substantial mucous lakes within tumors and comprises 3% of gastric carcinomas at the authors' institute.METHODS:The authors analyzed the clinicopathologic characteristics, mucin gene expression profiles, microsatellite instability (MSI), and status of the human epidermal growth factor receptor 2 (HER‐2) and epidermal growth factor receptor (EGFR) genes in 133 MGCs and compared them with the same variables in nonmucinous gastric carcinomas (NMGCs). In addition, the prognostic implications of clinicopathologic parameters were evaluated.RESULTS:Patients who had MGC had deeper invasion (P = .003), more frequent lymph node metastasis (P < .001), more advanced pathologic stage (P < .001), more frequent lymphatic invasion (P < .001), and lower disease‐specific survival rates (P < .0001) than patients who had NMGC. However, a mucinous histology per se was not identified as an independent prognostic factor. Negative mucin 1, cell surface associated (MUC1) status (P < .001); positive mucin 2, oligomeric mucus/gel‐forming (MUC2) status (P < .001); negative mucin 5AC, oligomeric mucus/gel‐forming (MUC5AC) status (P = .036); and negative mucin 6, oligomeric mucus/gel‐forming (MUC6) status (P < .001) were more frequent in MGCs. The frequency of MSI in MGC was not significantly different from that in NMGC. MGCs had a significantly lower incidence of HER‐2 protein overexpression (P = .046), HER‐2 gene amplification (P = .009), and EGFR protein overexpression (P = .017) than NMGCs; and multivariate analysis identified EGFR overexpression as a factor associated with a poor prognosis (P = .047). Patients with MGC who had a predominance of signet ring cells in mucin pools had poorer disease‐specific survival than patients who had MGC with predominant tubular differentiation (P = .017).CONCLUSIONS:The clinicopathologic and molecular characteristics of MGCs differed from those of NMGCs. Furthermore, the results indicated that EGFR overexpression and histologic subtyping by predominant tumor cell type in mucin pools may be helpful for predicting clinical outcome in patients with MGC.

A stochastic Lamb–Oseen vortex solution of the 2D Navier–Stokes equations
Authors: Sereno J. L. , Pereira J. M. C. , Pereira J. C. F. 
Published: May 2009

AbstractThe exact solution of the Lamb–Oseen vortices is reported for a random viscosity characterized by a Gamma probability density function. This benchmark solution allowed to quantify the analytic error of the polynomial chaos (PC) expansion as a function of the number of stochastic modes considered and compare it with its numerical counterpart. The last was obtained in the framework of the PC expansion method together with a finite difference numerical discretization of the resulting system of Navier–Stokes equations for the expansion modes considered. The obtained solution may be used to test other numerical approaches for the solution of the Navier–Stokes equations with random inputs. Copyright © 2009 John Wiley & Sons, Ltd.
