Abstract
The effects of the different steps of the root staining on the arbuscular mycorrhizal (AM) fungal rDNA extraction and amplification have been assessed. The results obtained using molecular techniques are compared with those obtained from fresh, non-stained leek roots. A modified staining procedure that eliminates heating, the use of hydrochloric acid and trypan blue, has been proved to be the most adequate to observe the AM colonisation in different plant species with/without lignified roots allowing at the same time the subsequent rDNA extraction and amplification from the stained roots. The staining technique decreased the sensitivity of the process and a higher number of roots had to be used to obtain enough material for a positive amplification. The extraction and amplification process was reliable up to 3 days after staining. A week after staining, the amplification was not dependable and after 2 weeks there was no amplification from stained material.

Abstract
PURPOSE To assess the value of MRCP in the detection of biliary complications after orthotopic liver transplantation. MATERIALS AND METHODS 27 transplanted patients with suspected biliary complication underwent a total of 34 MR and direct cholangiography procedures. MRCP were reviewed by 2 independent reviewers blinded to clinical and laboratory findings. The biliary tract was divided into 7 segments, and all lesions were evaluated using this segmental anatomy. Each segment was evaluated for the presence of dilatation, stenosis and intra-ductal debris. MRCP results were compared to results frpm direct cholangiography. RESULTS 216 (98%) of 221 biliary segments could be evaluated on MRCP, with good to excellent visualization in 179 (80%) cases. Segmental analysis showed sensitivity, specificity and accuracy values of 85%, 81% and 83% for the detection of biliary stenosis, 82%, 81% and 81% for the detection of biliary dilatation, and 60%, 88% and 80% for the detection of inyraductal debris. CONCLUSION MRCP is accurate for the detection of biliary stenosis and dilatation in patients after liver transplantation and provides an alternative to direct cholangiography.

Abstract
BACKGROUND AND PURPOSE Bladder diverticulectomy is classically performed by open surgery (extravesical, intravesical, or combined) or, less frequently, by an endoscopic approach for small diverticula. We used a celioscopic approach to diverticulectomy in order to assess its feasibility and the operative and postoperative complications. PATIENTS AND METHODS Five patients aged 55 to 76 years (mean 64.2 years) were treated by celioscopy between October 1999 and October 2001. All the diverticula had occurred as a result of infravesical obstruction by benign prostatic hyperplasia, which was treated at the same time by endoscopic resection of the prostate. An ipsilateral ureteral catheter was inserted during endoscopy. After creation of an umbilical minilaparotomy with the patient in the dorsal decubitus position, a 10-mm optical trocar was inserted, then two 5-mm trocars into the right and left iliac fossae, and a 10-mm subpubic trocar. Diverticular dissection was performed with a peritoneal approach in order to free the diverticular neck. After resection, the neck was closed in two planes by interrupted absorbable sutures, and a tightness test was performed. RESULTS The average operating time was 160 minutes (range 120-230 minutes), and the average blood loss was 150 mL (range 80-200 mL). There was no conversion to open surgery. The probe was removed on day 5 (range 3-7 days). No complication occurred, and the mean hospital stay was 5 days (range 4-6 days) with resumption of satisfactory micturation. CONCLUSION This technique is a promising alternative to classical surgery, as it is less aggressive and uses a smaller incision. Operative bleeding is minimal, and the technique is reproducible in experienced hands. However, the indications are limited with regard to the associated pathologies (size of the prostate in the present cases), the morphology, the site of the diverticulum, and the surgical history of the patient.

Abstract
In this study, a chiral capillary electrophoresis method was optimized and validated for E-6006, a thienylpyrazolylethanamine derivative (pKa 8.9). Enantioselectivity of neutral and anionic cyclodextrins (CDs) was evaluated at acid pH (3), obtaining cathodic and anodic migration, respectively. Hydroxypropyl-beta-CD, carboxymethyl-beta-CD and sulfobutyl ether-beta-CD led to similar and partial selectivity, whereas sulfate (S)-beta-CD produced baseline separation of the enantiomers. Four types of sulfated CDs were compared considering: cavity size (alpha, beta, gamma) and random substitution versus unique derivative (S-beta-CD, 6-heptakis-S-beta-CD). Complete peak separation was obtained in all cases, but with different affinity and binding strength. Some factors that play a role in the complex formation include: position/region/degree of substitution, size of CD cavity and proportion of derivatives in mixtures. Enantioaffinity and enantioselectivity increased with the average of sulfate groups/mol. Beta cavity size complexed better, although alpha and gamma cavities did not compromise separation. 6-Heptakis-S-beta-CD had less affinity and separation efficiency, attributed to its lower degree and unique position of substitution. The method was optimized with S-beta-CD (Aldrich, randomly substituted, 7-11 groups/mol). With this selector, the effect of pH value (3-9) was evaluated. Around pH 7 the cross-over point with change in the direction and order of migration was observed, associated with great enantioselectivity and long migration times. Fine tuning was done by adjusting the CD concentration and the buffer counterion. Definitive conditions were: uncoated silica capillary, 10 mM S-beta-CD-25 mM sodium phosphate, pH 3. Validation parameters are included.

Abstract
The 11 kDa C-terminal fragment of the proteolyticly matured surface antigen, PfMSP1, from Plasmodium falciparum is a promising malaria vaccine candidate. The soluble recombinant form of this naturally occurring fragment has been crystallized as a complex with the Fab of a specific murine monoclonal antibody. The crystals belong to the space group P2(1), with unit-cell parameters a = 51.8, b = 213.5,c = 60.0 A, beta =101.0 degrees, and with Z = 4. Diffraction data have been measured to 2.9 A resolution and a preliminary model of the complex has been determined by molecular replacement. The epitope recognised by G17.12 is located on the N-terminal EGF-like domain of the antigen.

Abstract
The simultaneous enantioselective separation of (+/-)-cizolirtine and its impurities: (+/-)-N-desmethylcizolirtine, (+/-)-cizolirtine-N-oxide and (+/- )-5-(alpha-hydroxybenzyl)-1-methylpyrazole was investigated by capillary electrophoresis. Electrokinetic chromatography with carboxymethyl-beta-CD (CM-beta-CD) and sulfobutyl-ether-beta-CD was tried, showing good enantioseparation but poor chemical selectivity. The four racemic pairs were baseline separated, in a single run, by cyclodextrin-modified micellar electrokinetic chromatography. The migration buffer composition was: (60 mM hydroxypropyl-beta-cyclodextrin-150 mM sodium dodecyl sulfate-50 mM disodium tetraborate, pH 9.2, in water)-butanol 95:5, v/v). Work was done to determine the effect of buffer components and their optimal concentration on selectivity. The method was validated with respect to enantioselectivity of cizolirtine as well as its degradation products and separation selectivity between the different components. Linearity, limit of detection, limit of quantitation and precision were also determined. This method is suitable for the enantiomeric purity determination and stability control of cizolirtine (racemic mixture or enantiomers) and its degradation products. Examples of electropherograms of (R)-cizolirtine degraded under stressed conditions are shown.

Abstract
N.BstNBI is a unique restriction endonuclease isolated from Bacillus stearothermophilus. We have characterized the recognition sequence and the cleavage site of N.BstNBI. Mapping of cleavage sites of N.BstNBI showed that it recognizes an asymmetric sequence, 5' GAGTC 3', and cleaves only on the top strand 4 base pairs away from its recognition sequence. To verify the nicking activity of N. BstNBI, we have constructed two plasmids containing a single recognition sequence (pNB1) or no recognition site (pNB0). When pNB1 and pNB0 were incubated with the enzyme, N.BstNBI nicked only the plasmid pNB1, suggesting that N.BstNBI is a specific nicking endonuclease.

Abstract
PURPOSE To assess the relationships between lipid levels and sexual maturity, independently of age-related differences, and to investigate possible differences related to sexual maturity across the percentiles of the lipid distributions. METHODS Fasting serum total cholesterol and triglyceride concentrations were measured in 6577 boys and 6605 girls, aged from 10 to 13 years, with different Tanner stages. The total cholesterol and triglyceride mean and percentile levels were estimated according to age and Tanner stage by ordinary least squares and percentile regression models, separately in both sexes. RESULTS In boys and girls, total cholesterol levels were significantly associated with pubertal stage after controlling for age. At age 12, the estimated mean levels in boys varied from 4.82 mmol/L for Tanner 1 to 4.41 for Tanner 5. The corresponding values were 5.05 and 4.62 mmol/L in girls, for whom the association with maturity was stronger in the upper than in the lower percentiles (p < 0.0001); between the extreme Tanner stages, the 95th percentiles of total cholesterol differed by 0.80 mmol/L, in comparison to 0.19 mmol/L for the 5th percentiles. Therefore, 1. 8% of girls and 0.7% of boys were classified differently whether Tanner stage was used or not to assess hypercholesterolemia (concentrations in the upper 5% of the distributions). Triglycerides were positively related to sexual maturity independently of age, but the discrepancies between classifications were lower; 1.1% in girls and 0.4% in boys. CONCLUSIONS Our findings emphasize the importance of sexual maturity, even for a given age, for interpreting lipid levels in children.

Abstract
The effects of Pratylenchus vulnus on growth and nutrition of Cadaman peach and Ishtara and Julior plum rootstocks were evaluated in a microplot experiment lasting two growing seasons. Cadaman peach was the only rootstock that showed suppressed growth for all growth parameters at the end of the first year. At the end of the second growing season, dry and fresh shoot weights as well as shoot length and root weights of Cadaman peach were reduced in nematode-inoculated microplots in comparison to uninoculated treatments. Stem diameter was not affected. Dry and fresh shoot weights were the only growth parameters affected by the nematode in Ishtara plum at the end of the second growing season, whereas Julior was not affected by P. vulnus infection. No nutrient deficiencies were detected by foliar analysis in any of the rootstocks and treatments. All the tested rootstocks were good hosts for P. vulnus, whose mean root population ranged from 1,670 (Cadaman) to 2,895 (Julior) nematodes/g of root.

Abstract
OBJECTIVE To assess whether the extent of abdominal fat distribution, as measured by the waist to hip ratio (WHR), might account for the sex differences in the levels of cardiovascular risk factors. DESIGN Cross-sectional age-matched study. SUBJECTS 1264 men and 1264 premenopausal women, aged 30-49 y, free from known cardiovascular diseases and diabetes, included in the prospective study, D.E.S.I.R. MEASUREMENTS (1) body mass index (BMI), WHR and blood pressures; (2) fasting concentrations of blood glucose, insulin, lipids and lipoprotein subfractions, and apolipoproteins; and (3) smoking status, physical activity, and alcohol consumption. RESULTS After taking into account age and BMI, there were gradual relationships, within and across sexes, between WHR and the levels of most lipids and lipoproteins, of fasting glucose and insulin, and, to a lesser extent, of blood pressures. In particular, men and women with similar BMI and WHR had similar levels of triglycerides. Multivariate regression analysis showed that the variance of cardiovascular risk factors explained by the model was increased when sex was included, after controlling for age, BMI and lifestyle habits (all P<0.01). If WHR was included in the model, sex had no additional effect on total cholesterol (P>0.09 for change in total r2 ) or triglycerides (P>0.40 for change in total r2). In contrast, for other cardiovascular risk factors, adjustment for covariates and WHR did not fully eliminate the sex differences, although WHR increased the variance explained with or without additional control for sex (all P<0.01). CONCLUSION The continuous increase of cardiovascular risk factors with WHR, especially for lipids and lipoproteins, suggests that the abdominal body fat distribution may partially explain the relative unhealthier cardiovascular risk profile of men.

Abstract
The ability to read and the phonological fitness of 89 youth (average age of 21.3 years) having difficulty with social and professional integration were examined. We observed that 64% of them (n = 57) had difficulty in reading. The results of the phonological and reading tests showed that developmental dyslexia constitutes, for 56% of the subjects (n = 32), or for 36% of the population of youth with difficulties, the explanatory framework for the delay of acquisition of these capacities. Reading difficulties for these youth were significantly linked to an alteration of the phonological treatment that effects: short-term verbal memory, auditory discrimination and meta-phonological fitness. The data tends to validate the hypothesis of the existence of a functional link between developmental dyslexia and illiteracy.

Abstract
MR cholangiopancreatography (MRCP) is a recent and exciting imaging modality that allows visualization of bile and pancreatic ducts without morbidity. Although the technique of MRCP is in its early stages of development and MRCP technology is progressing MRCP will undoubtedly replace traditional techniques such as diagnostic ERCP. This article describes MRCP findings in bile or pancreatic duct diseases, analyzes the accuracy of MRCP in these diseases, and discusses the potential role of MRCP in evaluating the pathology of the biliary tract and pancreas.

Abstract
New 2-(4-(4-azolylbutyl)piperazinyl)-, 2-(4-(4-azolylbutyl) piperazinylmethyl)-, 2-(4-(-azolylbutyl)homopiperazinyl)- and 2-(4-(4-azolylbutyl)homopiperazinylmethyl)benzimidazoles were synthesized, characterized and tested for in vitro and in vivo H1-antihistaminic activity. Structure-activity relationships implied that the best antihistaminic activity required the simultaneous presence of a homopiperazinylbenzimidazole system (or a methylene linker between the benzimidazole and the piperazine rings) and an unsubstituted pyrazole ring. 1-(2-Ethoxyethyl)-2-¿4-[4-(pyrazol-1-yl)butyl] homopiperazin-1-yl¿benzimidazole (17), as its dimaleate salt, has been chosen for further development.

Abstract
The L1 major capsid protein of human papillomavirus type 16 (HPV-16) was expressed in Sf-21 insect cells with a recombinant baculovirus. Virus-like particles obtained were purified and used to develop an enzyme-linked immunosorbent assay for detection of anti-HPV-16 antibodies in sera from 76 women with evidence of genital HPV infection and 79 controls. HPV-16-infected individuals developed antibodies directed at HPV-16 virions since reactivity against recombinant HPV-16L1 capsids was observed in 50% of them compared with only 6% in the general adult population. However, some cross-reactivities with sera from women infected with others HPV types were observed.

Abstract
Antibodies against eight synthetic peptides spanning different epitopes located on L1, L2, and E4 proteins of human papillomavirus (HPV) types 16, 6, and 11 were examined in sera from 73 women infected by HPV and from 139 healthy controls. Only three of these peptides were reactive. Two located on proteins L2 and E4 of HPV 16 seem type specific since antibodies to these peptides were detected, respectively, in 21% and 15% of the HPV 16 infected patients and in 2.5% and none of women infected by other HPVs. The third peptide located on the L1 protein of HPV 6 bears a common epitope since antibodies to this peptide were detected not only in 85% of women infected by HPV 6 or 11, but also in 82% of women infected by other HPVs, and in 74% and 71% of the control groups (10-12-year-old children and adults, respectively). In conclusion, none of the peptides investigated seems useful to develop ELISAs for serological diagnosis of HPV infection.

Abstract
A series of 7-(2,3-disubstituted-1-azetidinyl)-1,4-dihydro-6-fluoro-4- oxoquinoline- and -1,8-naphthyridine-3-carboxylic acids, with varied substituents at the 1-, 5-, and 8-positions, was prepared to study the effects on potency and physicochemical properties of the substituent at position 2 of the azetidine moiety. The activity of the title compounds was determined in vitro against Gram-positive and Gram-negative bacteria, and the in vivo efficacy of selected derivatives was determined using a mouse infection model. The X-ray crystal structures of 6b, 6c, and 6d were found to be in reasonable agreement with the corresponding AM1 calculated geometries. Correlations between antibacterial potency of all the synthesized 7-azetidinylquinolones and naphthyridines and their calculated electronic properties and experimental capacity factors were established. Antibacterial efficacy and pharmacokinetic and physicochemical properties of selected derivatives were compared to the relevant 7-(3-amino-1-azetidinyl) and 7-(3-amino-3-methyl-1-azetidinyl) analogues (for Part 1, see: J. Med. Chem. 1993, 36, 801-810). A combination of a cyclopropyl or a substituted phenyl group at N-1 and a trans-3-amino-2-methyl-1-azetidinyl group at C-7 conferred the best overall antibacterial, pharmacokinetic, and physicochemical properties to the azetidinylquinolones studied.
