Glutaric acidemia type 1
Authors: Hedlund Gary L. , Longo Nicola , Pasquali Marzia
Published: April 2006

Glutaric acidemias comprise different disorders resulting in an increased urinary excretion of glutaric acid. Glutaric acidemia type 1 (GA‐1) is an autosomal recessive disorder of lysine, hydroxylysine, and tryptophan metabolism caused by deficiency of glutaryl‐CoA dehydrogenase. It results in the accumulation of 3‐hydroxyglutaric and glutaric acid. Affected patients can present with brain atrophy and macrocephaly and with acute dystonia secondary to striatal degeneration in most cases triggered by an intercurrent childhood infection with fever between 6 and 18 months of age. This disorder can be identified by increased glutaryl (C5DC) carnitine on newborn screening. Urine organic acid analysis indicates the presence of excess 3‐OH‐glutaric acid, and urine acylcarnitine profile shows glutaryl carnitine as the major peak. Therapy consists in carnitine supplementation to remove glutaric acid, a diet restricted in amino acids capable of producing glutaric acid, and prompt treatment of intercurrent illnesses. Early diagnosis and therapy reduce the risk of acute dystonia in patients with GA‐1. © 2006 Wiley‐Liss, Inc.
Methylmalonic and propionic aciduria
Authors: Deodato Federica , Boenzi Sara , Santorelli Filippo M. , Dionisi‐Vici Carlo
Published: April 2006

Methylmalonic and propionic aciduria (PA) are the most frequent forms of branched‐chain organic acidurias. These autosomal recessive disorders result from deficient activity of methylmalonyl‐CoA mutase and propionyl‐CoA carboxylase, respectively. Clinically, acute or chronic neurologic signs are caused by the accumulation of toxic compounds proximal to the metabolic block. Phenotype varies from severe neonatal‐onset forms with high mortality and poor outcome to milder forms with a later onset. In both cases the clinical course is dominated by the risk of relapses of life‐threatening episodes of metabolic decompensation and of severe organ failure. Despite improvement of treatment, the overall outcome remains disappointing with no major differences between the two diseases. The diagnosis is based on the presence of characteristic compounds in body fluids as detected by organic acid analysis in urine and acylcarnitine profile in blood. Therapy is based on low‐protein high‐energy diet, carnitine supplementation, and metronidazole. Some patients with methylmalonic aciduria (MMA) respond to pharmacological doses of vitamin B12. Given the poor long‐term prognosis, liver transplantation has been recently attempted as an alternative therapy to conventional medical treatment to cure the underlying metabolic defect. Nevertheless, the overall experience to date does not clearly demonstrate its effectiveness in preventing further deterioration or improving survival and quality of life. The recent implementation of neonatal screening by electrospray tandem mass spectrometry has decreased early mortality and improved the short‐term outcome, without changing the detection rate of both diseases in the screening population compared to clinically detected cases. However, the limited number of patients and the short duration of their follow‐up do not yet permit drawing final conclusions on its effect on the long‐term outcome of methylmalonic and propionic acidemia. © 2006 Wiley‐Liss, Inc.
Clinical, biochemical, and molecular spectrum of hyperargininemia due to arginase I deficiency
Authors: Scaglia Fernando , Lee Brendan
Published: April 2006

The urea cycle consists of six consecutive enzymatic reactions that convert waste nitrogen into urea. Urea cycle disorders are a group of inborn errors of hepatic metabolism that often result in life threatening hyperammonemia and hyperglutaminemia. Deficiencies of all of the enzymes of the cycle have been described and although each specific disorder results in the accumulation of different precursors, hyperammonemia and hyperglutaminemia are common biochemical hallmarks of these disorders. Arginase is the enzyme involved in the last step of the urea cycle. It catalyzes the conversion of arginine to urea and ornithine. The latter reenters the mitochondrion to continue the cycle. Hyperargininemia is an autosomal recessive disorder caused by a defect in the arginase I enzyme. Unlike other urea cycle disorders, this condition is not generally associated with a hyperammonemic encephalopathy in the neonatal period. It typically presents later in childhood between 2 and 4 years of age with predominantly neurological features. If untreated, it progresses with gradual developmental regression. A favorable outcome can be achieved if dietary treatment and alternative pathway therapy are instituted early in the disease course. With this approach, further neurological deterioration is prevented and partial recovery of skills ensues. Early diagnosis of this disorder through newborn screening programs may lead to a better outcome. This review article summarizes the clinical characterization of this disorder; as well as its biochemical, enzymatic, and molecular features. Treatment, prenatal diagnosis and diagnosis through newborn screening are also discussed. © 2006 Wiley‐Liss, Inc.
Toughening modification of PBT/PC blends with PTW and POE
Authors: Bai Huiyu , Zhang Yong , Zhang Yinxi , Zhang Xiangfu , Zhou Wen
Published: April 2006

New toughened poly(butylene terephthalate) (PBT)/bisphenol A polycarbonate (PC) blends were obtained by melt blending with ethylene–butylacrylate–glycidyl methacrylate copolymer (PTW) and ethylene‐1‐octylene copolymer (POE) in a twin‐screw extruder. The mechanical properties of PBT/PC blends were investigated. The presence of PTW or POE could improve the mechanical properties except for the tensile strength and flexural properties of the PBT/PC blends. However, a combination use of PTW and POE had a strong synergistic effect, leading to remarkable increases in the impact strength, elongation at break, and Vicat temperature and some reduction of the tensile strength and flexural properties. The relationship between mechanical properties and morphology of the PBT/PC/PTW/POE blends was studied. The morphology was observed by scanning electron microscopy and the average diameter of dispersed phase was determined by image analysis, and the critical interparticle distance for PBT/PC was determined. © 2006 Wiley Periodicals, Inc.

Synthesis, characterization, and thermodynamic properties of poly(3‐mesityl‐2‐hydroxypropyl methacrylate)
Authors: Açikses Aslişah , Kaya Ismet , Horoz Gökhan
Published: April 2006

Poly(3‐mesityl‐2‐hydroxypropyl methacrylate) (PMHPMA) was synthesized in a 1,4‐dioxane solution with 2,2′‐azobisisobutyronitrile as the initiator at 60°C. The homopolymer and its monomer were characterized with 1H‐ and 13C‐NMR, Fourier transform infrared, differential scanning calorimetry, thermogravimetric analysis, size exclusion chromatography, and elemental analysis techniques. According to size exclusion chromatography analysis, the number‐average molecular weight, weight‐average molecular weight, and polydispersity index of PMHPMA were 65,864 g/mol, 215,375 g/mol, and 3.275, respectively. According to thermogravimetric analysis, the carbonaceous residue value of PMHPMA was 14% at 500°C. The values of the specific retention volume, adsorption enthalpy, sorption enthalpy, sorption free energy, sorption entropy, partial molar free energy, partial molar heat of mixing, weight fraction activity coefficient of solute probes at infinite dilution (Ω), and Flory–Huggins interaction parameter (χ) were calculated for the interactions of PMHPMA with selected alcohols and alkanes by the inverse gas chromatography method at various temperatures. According to Ω and χ, selected alcohols and alkanes were nonsolvents for PMHPMA at 423–453 K. Also, the solubility parameter of PMHPMA (δ2) was found to be 24.24 and 26.33 (J/cm3)0.5 from the slope and intercept of (δ/RT) − χ/V1 = (2δ2/RT)δ1 − δ/RT at 443 K, respectively [where δ1 is the solubility parameter of the probe, V1 is the molar volume of the solute, T is the column temperature (K), and R is the universal gas constant]. The glass‐transition temperature of PMHPMA was found to be 386 and 385 K by inverse gas chromatography and differential scanning calorimetry techniques, respectively. © 2006 Wiley Periodicals, Inc.

Bayesian solvency analysis with autocorrelated observations
Authors: Mendoza M. , E. Nieto‐Barajas L.
Published: April 2006

Most financial institutions are required to comply with a minimum capital rule in order to face their obligations during a given period of time. Due to the random nature of the financial flows involved, the problem of assessing the amount of capital required must be analysed within a stochastic framework and the solution can be reduced to the estimation of a selected quantile. Given the financial impact of a specific capital requirement, a proper and careful choice of the underlying model is of great relevance. Here, we address the problem for insurance companies by proposing an autocorrelated model to describe the relative severity after a suitable transformation and compare the results with those of a model, which assumes independence among observations. We undertake a full Bayesian analysis and derive the reference priors for the models. Results are illustrated with a real data set from the Mexican insurance industry.

Revisiting distributed lag models through a Bayesian perspective
Authors: R. Ravines Romy , M. Schmidt Alexandra , S. Migon Helio
Published: April 2006

This paper aims to show to practitioners how flexible and straightforward the implementation of the Bayesian paradigm can be for distributed lag models within the Bayesian dynamic linear model framework.

Distributed lag models are of importance when it is believed that a covariate at time t, say Xt, causes an impact on the mean value of the response variable, Yt. Moreover, it is believed that the effect of X on Y persists for a period and decays to zero as time passes by. There are in the literature many different models that deal with this kind of situation. This paper aims to review some of these proposals and show that under some fairly simple reparametrization they fall into a particular case of a class of Dynamic Linear Models (DLM), the transfer functions models. Inference is performed following the Bayesian paradigm. Samples from the joint posterior distribution of the unknown quantities of interest are easily obtained through the use of Markov chain Monte Carlo (MCMC) methods. The computation is simplified by the use of the software WinBugs.

As an example, a consumption function is analysed using the Koyck transformation and the transfer function models. Then a comparison is made with classical cointegration techniques. Copyright © 2006 John Wiley & Sons, Ltd.
Duplication of 5q15‐q23.2: Case report and literature review
Authors: Douyard Jaclyn , Hawley Pamela , Shaham Meira , Kimonis Virginia
Published: April 2006

BACKGROUND

Pure partial trisomy of chromosome 5q is rare and cases have ranged over the entire region, making it difficult to describe a good phenotypic correlation to the cytogenetic duplication.

CASE

We present a 4.5‐year‐old girl with a de novo direct duplication of chromosome 5q15‐q23.2. She has moderate developmental delay with lack of speech, microcephaly, and subtle dysmorphic features including prominent forehead, bulbous nose, epicanthic folds, protruding tongue, and slightly posteriorly‐rotated ears.

CONCLUSIONS

A comparison is made with other similar duplication cases reported in the literature and a general description of a proximal 5q duplication phenotype is given, with lack of speech as the principal feature. Birth Defects Research (Part A), 2006. © 2006 Wiley‐Liss, Inc.
Characterization of partially folded intermediates of papain in presence of cationic, anionic, and nonionic detergents at low pH
Authors: Naeem Aabgeena , Fatima Sadaf , Hasan Khan Rizwan
Published: April 2006

A systematic investigation of the effects of detergents [Sodium dodecyl sulphate (SDS), hexa decyltrimethyl ammonium bromide (CTAB) and Tween‐20] on the structure of acid‐unfolded papain (EC.3.4.22.2) was made using circular dichroism (CD), intrinsic tryptophan fluorescence, and 1‐anilino 8‐sulfonic acid (ANS) binding. At pH 2, papain exhibits a substantial amount of secondary structure and is relatively less denatured compared with 6 M GdnHCl (guanidine hydrochloride) but loses the persistent tertiary contacts of the native state. Addition of detergents caused an induction of α‐helical structure as evident from the increase in the mean residue ellipticity value at 208 and 222 nm. Near‐UV CD spectra also showed the regain of native‐like spectral features in the presence of 8 mM SDS and 3.5 mM CTAB. Induction of structure in acid‐unfolded papain was greater in the presence SDS followed by CTAB and Tween‐20. Intrinsic tryptophan fluorescence studies indicate the change in the environment of tryptophan residues upon addition of detergents to acid‐unfolded papain. Addition of 8 mM SDS resulted in the loss of ANS binding sites exhibited by a decrease in ANS fluorescence intensity, suggesting the burial of hydrophobic patches. Maximum ANS binding was obtained in the presence of 0.1 mM Tween‐20 followed by CTAB, indicating a compact “molten‐globule”–like conformation with enhanced exposure of hydrophobic surface area. Acid‐unfolded papain in the presence of detergents showed the partial recovery of enzymatic activity. These results suggest that papain at low pH and in the presence of SDS exists in a partially folded state characterized by native‐like secondary structure and tertiary folds. While in the presence of Tween, acid‐unfolded papain exists as a compact intermediate with molten‐globule–like characteristics, viz. enhanced hydrophobic surface area and retention of secondary structure. While in the presence of CTAB it exists as a compact intermediate with regain of native‐like secondary and partial tertiary structure as well as high ANS binding with the partially recovered enzymatic activity, i.e., a molten globule state with tertiary folds. © 2006 Wiley Periodicals, Inc.

Authors: Hao DaCheng , Sun Jie , Furnes Bjarte , Schlenk Daniel , Li MiaoXin , Yang ShengLi , Yang Ling
Published: April 2006

The aims of this study were to analyze flavin‐containing monooxygenase3 (FMO3)polymorphisms and allele and genotype frequencies in 256 Han Chinese and 50 African‐American individuals, to compare the allele and genotype frequencies of these populations with those of other world populations. For Han Chinese, genotyping of three common single nucleotide polymorphisms, E158K, V257M and E308G was performed by polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP). For African‐Americans, genotyping of all coding exons was performed by modified PCR‐single strand conformational polymorphism (SSCP). Evolutionary rates ofFMO3were estimated computationally. We found that there were significant differences in allele and genotype frequencies among Han Chinese, African‐Americans and other world populations. In Han Chinese, the minor allele frequencies (MAFs) were 0.229 (E158K), 0.203 (V257M) and 0.148 (E308G), respectively. In African‐Americans, MAFs were 0.48 (E158K), 0.05 (V257M) and 0 (E308G), respectively. There was rapid evolution during the divergence of primateFMO3. This is the first report comparingFMOalleles and genotypes between Han Chinese and African‐Americans. A Han Chinese population database has been established for three gene polymorphisms. The data presented here justify further pharmacogenetic studies for potentially optimizing recommended drug dosages and evaluating relationships with disease processes.

One‐Pot Enantioselective Aziridination of Olefins Catalyzed by a Copper(I) Complex of a Novel Diimine Ligand by Using PhI(OAc)2 and Sulfonamide as Nitrene Precursors
Authors: Wang Xisheng , Ding Kuiling
Published: April 2006

A novel chiral C2‐symmetric 1,4‐diamine with multistereogenic centers at the backbone of the ligand has been synthesized from cheap natural product D‐mannitol through multistep transformations. Its diimine derivative (3 a) was found to be highly effective for the enantioselective control of the copper‐catalyzed asymmetric aziridination of olefin derivatives with PhINTs as the nitrene source, affording the corresponding N‐sulfonylated azirindine derivatives in good to excellent yields with up to 99 % ee (ee=enantiomeric excess). The catalyst system discovered in the present work was also extended to a one‐pot enantioselective aziridination by using sulfonamide/iodobenzene diacetate as the nitrene source. In this case, most reactions proceeded smoothly to give the corresponding products in moderate yields with good to excellent enantiomeric excesses (75–96 % ee).
Photosensitized Oxidation of Sulfides: Discriminating between the Singlet‐Oxygen Mechanism and Electron Transfer Involving Superoxide Anion or Molecular Oxygen
Authors: Bonesi Sergio M. , Manet Ilse , Freccero Mauro , Fagnoni Maurizio , Albini Angelo
Published: April 2006

The oxidation of diethyl and diphenyl sulfide photosensitized by dicyanoanthracene (DCA), N‐methylquinolinium tetrafluoroborate (NMQ+), and triphenylpyrylium tetrafluoroborate (TPP+) has been explored by steady‐state and laser flash photolysis studies in acetonitrile, methanol, and 1,2‐dichloroethane. In the Et2S/DCA system sulfide‐enhanced intersystem crossing leads to generation of 1O2, which eventually gives the sulfoxide via a persulfoxide; this mechanism plays no role with Ph2S, though enhanced formation of 3DCA has been demonstrated. In all other cases an electron‐transfer (ET) mechanism is involved. Electron‐transfer sulfoxidation occurs with efficiency essentially independent of the sulfide structure, is subject to quenching by benzoquinone, and does not lead to Ph2SO cooxidation. Formation of the radical cations R2S.+ has been assessed by flash photolysis (medium‐dependent yield, dichloroethane≫CH3CN>CH3OH) and confirmed by quenching with 1,4‐dimethoxybenzene. Electron‐transfer oxidations occur both when the superoxide anion is generated by the reduced sensitizer (DCA.−, NMQ.) and when this is not the case (TPP.). Although it is possible that different mechanisms operate with different ET sensitizers, a plausible unitary mechanism can be proposed. This considers that reaction between R2S.+ and O2.− mainly involves back electron transfer, whereas sulfoxidation results primarily from the reaction of the sulfide radical cation with molecular oxygen. Calculations indeed show that the initially formed fleeting complex RS2+⋅⋅⋅OO. adds to a sulfide molecule and gives strongly stabilized R2SO.+OSR2 via an accessible transition state. This intermediate gives the sulfoxide, probably via a radical cation chain path. This mechanism explains the larger scope of ET sulfoxidation with respect to the singlet‐oxygen process.
Controlled Assembly of a Heterogeneous Single‐Site Ethylene Trimerization Catalyst as Probed by X‐ray Absorption Spectroscopy
Authors: Nenu Cristina N. , van Lingen Joost N. J. , de Groot Frank M. F. , Koningsberger Diek C. , Weckhuysen Bert M.
Published: April 2006

X‐ray absorption spectroscopy at the Cr K‐ and L2,3‐edges was used to study the assembling process of a heterogeneous Cr‐based single‐site catalyst. The starting point was a Phillips‐type system with monochromate species anchored on a silica surface, which was first reduced to a variety of different surface CrII species. The reduced sample was modified with a 1,3,5‐tribenzylhexahydro 1,3,5‐triazine (TAC) ligand in the presence of CH2Cl2 as solvent to yield a heterogeneous single‐site Cr‐based catalyst active in the trimerization of ethylene. The molecular structure of the resultant catalytic material consists of distorted octahedral CrIII species. The extended X‐ray absorption fine‐structure (EXAFS) spectroscopy fitting procedure in R space up to 2.5 Å showed that the synthesis leads to coordination with a TAC ligand. The fit also shows that it was possible to complete the six‐fold environment around CrIII with two oxygen atoms and one chloride ligand. This chloride ligand is formed in a redox process from the solvent and is responsible for the oxidation of surface CrII to CrIII. The obtained geometry and the local environment of the surface complex are discussed in light of its homogeneous counterpart and confirm the single‐site characteristics of the prepared catalytic material.
