Application of bioluminescence ATP measurement for evaluation of fungal viability of foxing spots on old documents
Authors: Rakotonirainy Malalanirina Sylvia , Dubar Pauline 
Published: June 2012

ABSTRACTAn adenosine triphosphate (ATP) bioluminescence‐based protocol was tested to assess the viability of fungal species in old documents damaged by foxing. Foxing appears as scattered yellow brownish‐red stains, damaging the aesthetics of documents and their long‐term readability. In the field of cultural heritage conservation, the debate over the mechanism of foxing is ongoing. Previous studies found evidence of mold‐like structures in some coloured areas; however, many species have not yet been identified and their role in the phenomenon is not understood. To better understand their involvement in this type of paper decay, we focused our attention first on their viability. We demonstrated the reliability and sensitivity of the ATP bioluminescence assay compared with conventional methods based on cultivation, which has rarely given rise to in vitro growth from foxed papers. From nine books dating back from the 19th and 20th centuries, the mean ATP amount of foxed spots ranged from 0.29 to 3.63 ng/cm2, suggesting the presence of strains inside the brownish spots and providing evidence of their viability. Outside the spots, ATP content was considered negligible, with a mean ATP amount of 0 to 0.03 ng/cm2. ATP assay appears to be a useful and robust method for the detection and quantification of viable elements in foxing spots. Copyright © 2012 John Wiley & Sons, Ltd.

Published: June 2012

ABSTRACTIn this study, we report for the first time a one‐pot approach for the synthesis of new CdSeTeS quaternary‐alloyed quantum dots (QDs) in aqueous phase by microwave irradiation. CdCl2 was used as a Cd precursor during synthesis, NaHTe and NaHSe were used as Te and Se precursors and mercaptopropionic acid (MPA) was used as a stabilizer and source of sulfur. A series of quaternary‐alloyed QDs of different sizes were prepared. CdSeTeS QDs exhibited a wide emission range from 549 to 709 nm and high quantum yield (QY) up to 57.7 %. Most importantly, the quaternary‐alloyed QDs possessed significantly long fluorescence lifetimes > 100 ns as well as excellent photostability. Results of high‐resolution transmission electron microscopy (HRTEM), energy dispersive X‐ray spectroscopy (EDX) and powder X‐ray diffraction (XRD) spectroscopy showed that the nanocrystals possessed a quaternary alloy structure with good crystallinity. Fluorescence correlation spectroscopy (FCS) showed that QDs possessed good water solubility and monodispersity in aqueous solution. Furthermore, CdSeTeS QDs were modified with alpha‐thio‐omega‐carboxy poly(ethylene glycol) (HS‐PEG‐COOH) and the modified QDs were linked to anti‐epidermal growth factor receptor (EGFR) antibodies. QDs with the EGFR antibodies as labeling probes were successfully applied to targeted imaging for EGFR on the surface of SiHa cervical cancer cells. We believe that CdSeTeS QDs can become useful probes for in vivo targeted imaging and clinical diagnosis. Copyright © 2012 John Wiley & Sons, Ltd.
Engineering of self‐sustaining systems: Substituting the yeast glucose transporter plus hexokinase for the Lactococcus lactis phosphotransferase system in a Lactococcus lactis network in silico
Authors: Adamczyk Malgorzata , Westerhoff Hans V. 
Published: June 2012

AbstractThe success rate of introducing new functions into a living species is still rather unsatisfactory. Much of this is due to the very essence of the living state, i.e. its robustness towards perturbations. Living cells are bound to notice that metabolic engineering is being effected, through changes in metabolite concentrations. In this study, we asked whether one could engage in such engineering without changing metabolite concentrations. We have illustrated that, in silico, one can do so in principle. We have done this for the case of substituting the yeast glucose transporter plus hexokinase for the Lactococcus lactis phosphotransferase system, in an L. lactis network, this engineering is 'silent' in terms of metabolite concentrations and almost all fluxes.
Wasserlinsen als Nutzpflanzen
Authors: Appenroth Klaus‐J. , Lam Eric 
Published: June 2012

AbstractVertreter aus der Familie der Wasserlinsengewächse sind nicht nur interessant, weil sie die kleinsten Blütenpflanzen repräsentieren, sie besitzen vielmehr auch die höchste Produktivität bei der Erzeugung von Biomasse. Ihre Produktion steht nicht in Konkurrenz zu anderen landwirtschaftlichen Nutzpflanzen, da sie auf Aquakultur angewiesen sind. Zudem trägt ihre Kultivierung nicht zur weiteren Eutrophierung der Gewässer bei. Vielmehr können sie auf kommunalen und landwirtschaftlichen Abwässern kultiviert werden und nehmen im Verlauf von Vermehrung und Wachstum die Nährstoffe auf. Sie können daher zur Gewässerreinigung eingesetzt werden. Die erzeugte Biomasse ist kein Abfall, sondern wertvolles Ausgangsmaterial für Tierernährung und zur Erzeugung von Bioalkohol. Die Untersuchungen haben inzwischen bereits das Forschungslabor teilweise verlassen und werden in technischen Pilotanlagen fortgesetzt, so in New Jersey und North Carolina (USA), Chengdu (China), und Armidale (Australien).
Europäische Trockenrasen schlagen tropische Regenwälder
Authors: Dengler Jürgen 
Published: June 2012

AbstractTropische Regenwälder gelten als die artenreichsten Lebensräume der Erde. Nun zeigt eine neue Studie, dass bei Betrachtung kleiner Flächen europäische Halbtrockenrasen die Gefäßpflanzendiversität der Tropenwälder übertreffen. Paradoxerweise könnte gerade die (extensive) menschliche Nutzung einer der Gründe für den hohen Artenreichtum von Grasländern der gemäßigten Zone sein. Heute ist dieser Vegetationstyp durch Nutzungsaufgabe und ‐intensivierung ähnlich stark gefährdet wie tropische Regenwälder.

Published: June 2012

AbstractBackgroundContemporary liver surgery practice must accurately assess operative risk in increasingly elderly populations with greater co-morbidity. This study evaluated preoperative cardiopulmonary exercise testing (CPET) in high-risk patients undergoing hepatic resection.MethodsIn a prospective cohort referred for liver resection, patients aged over 65 years (or younger with co-morbidity) were evaluated by preoperative CPET. Data were collected prospectively on functional status, postoperative complications and survival.ResultsTwo hundred and four patients were assessed for hepatic resection, of whom 108 had preoperative CPET. An anaerobic threshold (AT) of 9·9 ml O2 per kg per min predicted in-hospital death and subsequent survival. Below this value, AT was 100 per cent sensitive and 76 per cent specific for in-hospital mortality, with a positive predictive value (PPV) of 19 per cent and a negative predictive value (NPV) of 100 per cent: no deaths occurred above the threshold. Age and respiratory efficiency in the elimination of carbon dioxide (V̇E/V̇CO2) at AT were statistically significant predictors of postoperative complications. Receiver operating characteristic (ROC) curve analysis showed that a threshold of 34·5 for V̇E/V̇CO2 at AT provided a specificity of 84 per cent and a sensitivity of 47 per cent, with a PPV of 76 (95 per cent confidence interval (c.i.) 58 to 88) per cent and a NPV of 60 (48 to 72) per cent for postoperative complications. Long-term survival of those with an AT of less than 9·9 ml O2 per kg per min was significantly worse than that of patients with a higher AT (hazard ratio for mortality 1·81, 95 per cent c.i. 1·04 to 3·17; P = 0·036).ConclusionCPET provides a useful prognostic adjunct in the preoperative assessment of patients undergoing hepatic resection.

Published: June 2012

AbstractBackgroundCombined vasculobiliary injury is a serious complication of cholecystectomy. This study examined medium- to long-term outcomes after such injury.MethodsPatients referred to this institution with Strasberg type E bile duct injuries were identified from a prospectively maintained database (1990–2010). Long-term outcomes were evaluated by chart review.ResultsSixty-three patients were referred with bile duct injury alone (45 patients) or vasculobiliary injury (18). Thirty patients (48 per cent) had septic complications before transfer. Twenty-six patients (41 per cent) had long-term biliary complications over a median follow-up of 96 (range 12–245) months. Nine patients (3 with bile duct injury, 6 with vasculobiliary injury) required further interventions after a median of 22 (8–38) months; five required biliary surgical revision and four percutaneous dilatation of biliary strictures. Vasculobiliary injury and injury-related sepsis were independent risk factors for treatment failure: hazard ratio 7·79 (95 per cent confidence interval 2·80 to 21·70; P &lt; 0·001) and 4·82 (1·69 to 13·68; P = 0·003) respectively.ConclusionOutcome following bile duct injury repair was worse in patients with concomitant vasculobiliary injury and/or sepsis.

Abstract

Background
The liver is known to regenerate following partial hepatectomy (PH), but little is known about the timing and completeness of regeneration relative to the resected volume. This study examined whether liver volume regeneration following PH and its completeness 6 months after surgery is related to the resected volume.

Methods
A consecutive series of patients undergoing PH were included. All patients underwent preoperative computed tomography (CT) before and 7 days after surgery. Additional scans were performed 6 months after operation. Preoperative total liver volume (TLV), resected volume, future liver remnant (FLR) and liver remnant (LR) volumes were measured on CT images by freehand drawing of regions of interest in the portal venous phase on 2-mm thick slices. Regeneration indices were calculated at 7 days (RIearly) and 6 months (RItotal) using the formula 100 × (LR volume—FLR volume)/FLR volume. Patients were classified into five groups based on resected volume as a percentage of TLV: 0–19, 20–39, 40–59, 60–69 and at least 70 per cent in groups 1–5 respectively.

Results
Ninety-one patients were enrolled. RIearly varied from 11 to 66 per cent in groups 1–5 (P &lt; 0·001). RIearly did not increase linearly with increasing resection volume and a plateau was seen from group 3 and above. In contrast, RItotal was related linearly to resected volume; values ranged from 21 to 233 per cent in groups 1–5 (P &lt; 0·001). At 7 days, LR volume represented 97, 87, 70, 58 and 41 per cent of TLV in groups 1–5. At 6 months, respective values were 102, 99, 87, 82 and 91 per cent.

Conclusion
Early postoperative liver volume regeneration was not related linearly to resected volume. At 6 months after surgery, RI was related linearly to resected volume, but LRs had not yet regenerated to preoperative TLV.
Anatomical and mechanical relationship between the proximal attachment of adductor longus and the distal rectus sheath

Published: June 2012

AbstractThe objectives of this study were to investigate the anatomical relationship between the proximal adductor longus (AL) and rectus abdominis muscles and to determine whether unilateral loading of AL results in strain transmission across the anterior pubic symphysis to the contralateral distal rectus sheath. Bilateral dissections were conducted on 10 embalmed cadavers. Strain transfer across the pubic symphysis was examined on seven of these cadavers. An AL contraction was simulated by applying a controlled load in the direction of its proximal tendinous fibers, and the resultant strain in the contralateral distal rectus sheath was measured using a foil‐type surface mounted microstrain gage. Adductor longus attached to the antero‐inferior aspect of the pubis. In 18 of the 20 limbs, the proximal attachment of AL was tendinous on its superficial surface and muscular on its deep surface. The proximal AL tendon was found in most instances to have secondary communications with structures such as the contralateral distal rectus sheath, pubic symphysis anterior capsule, ilio‐inguinal ligament, and contralateral proximal AL tendon. Despite these consistent anatomical observations, strain measured in the contralateral distal rectus sheath upon unilateral loading of the proximal AL varied considerably between cadavers. Measured strain had an average ± 1SD of 0.23 ± 0.43%. The proximal attachment of AL contributes to an anatomical pathway across the anterior pubic symphysis that is likely required to withstand the transmission of large forces during multidirectional athletic activities. This anatomical relationship may be a relevant factor in explaining the apparent vulnerability of the AL and rectus abdominis attachments to injury. Clin. Anat. 2013. © 2012 Wiley Periodicals, Inc.
Novel (Phenylethynyl)pyrene–LNA Constructs for Fluorescence SNP Sensing in Polymorphic Nucleic Acid Targets

Published: June 2012

AbstractWe describe fluorescent oligonucleotide probes labeled with novel (phenylethynyl)pyrene dyes attached to locked nucleic acids. Furthermore, we prove the utility of these probes for the effective detection of single‐nucleotide polymorphisms in natural nucleic acids. High‐affinity hybridization of the probes and excellent fluorescence responses to single‐base mismatches in DNA/RNA targets are demonstrated in model dual‐probe and doubly labeled probe formats. This stimulated us to develop two diagnostic systems for the homogeneous detection of a drug‐resistance‐causing mutation in HIV‐1 protease cDNA and RNA gene fragments. Target sequences were obtained by analysis of 200 clinical samples from patients currently receiving anti‐HIV/AIDS combination therapy at the Russian Federal AIDS Center. Using these fluorescent oligonucleotides, we were able to detect the target mutation despite all the challenges of the natural targets, that is, the presence of additional mutations, neighboring sequence variation, and low target concentration, which typically reduce binding and effectiveness of sensing by fluorescent oligonucleotides.
The Butenolide Signaling Molecules SRB1 and SRB2 Induce Lankacidin and Lankamycin Production in Streptomyces rochei

Published: June 2012

AbstractNew signaling molecules that induce lankacidin and lankamycin production in Streptomyces rochei were extracted from the culture filtrate and purified by Sephadex LH20 and silica gel chromatography with the help of bioassay. Chiral HPLC and ESI‐MS analyses indicated the presence of two active components—SRB1 and SRB2—and their molecular formulas were established to be C15H24O5 and C16H26O5, respectively. By extensive NMR analysis, SRB1 and SRB2 were determined to be 2‐(1′‐hydroxy‐6′‐oxo‐8′‐methylnonyl)‐3‐methyl‐4‐hydroxybut‐2‐en‐1,4‐olide and 2‐(1′‐hydroxy‐6′‐oxo‐8′‐methyldecyl)‐3‐methyl‐4‐hydroxybut‐2‐en‐1,4‐olide, respectively. These structures were finally confirmed by chemical synthesis and the absolute configuration at C‐1′ was determined to be R in each case. The synthetic 1′R isomers induced production of lankacidin and lankamycin at around 40 nM concentrations. SRB1 and SRB2 are therefore distinct from the well‐known 2,3‐disubstituted γ‐butyrolactone molecules such as A‐factor, virginia butanolide, and SCB1 and and belong, like avenolide, recently isolated from Streptomyces avermitilis, to the γ‐butenolide family.
