Mycobacterium tuberculosis salicylate synthase (MbtI), a member of the chorismate‐utilizing enzyme family, catalyses the first committed step in the biosynthesis of the siderophore mycobactin T. This complex secondary metabolite is essential for both virulence and survival of M. tuberculosis, the etiological agent of tuberculosis (TB). It is therefore anticipated that inhibitors of this enzyme may serve as TB therapies with a novel mode of action. Herein we describe the first inhibition study of M. tuberculosis MbtI using a library of functionalized benzoate‐based inhibitors designed to mimic the substrate (chorismate) and intermediate (isochorismate) of the MbtI‐catalyzed reaction. The most potent inhibitors prepared were those designed to mimic the enzyme intermediate, isochorismate. These compounds, based on a 2,3‐dihydroxybenzoate scaffold, proved to be low‐micromolar inhibitors of MbtI. The most potent inhibitors in this series possessed hydrophobic enol ether side chains at C3 in place of the enol‐pyruvyl side chain found in chorismate and isochorismate.

BACKGROUND:

High‐intensity focused ultrasound (HIFU) is a new, noninvasive technique with potential to ablate and inactivate tumors. Treatment of solid tumors with HIFU has been reported. In this study, the safety and effects of HIFU in the clinical therapy of malignant bone tumors were assessed.

METHODS:

Biochemical markers and magnetic resonance imaging (MRI) or positron emission tomography (PET)‐computed tomography (CT) were used to evaluate 25 patients with malignant bone tumors before and after HIFU treatment.

RESULTS:

HIFU resulted in significant improvement in biochemical markers, and no severe complications were observed. After HIFU treatment, 21 (87.5%) patients were completely relieved of pain, and 24 (100%) experienced significant relief. On the basis of MRI or PET‐CT, HIFU was effective: For patients with primary bone tumors, 6 (46.2%) had a complete response, 5 (38.4%) had a partial response, 1 (7.8%) had a moderate response, and 1 suffered progressive disease; the response rate was 84.6%. For patients with metastatic bone tumors, 5 (41.7%) had complete response, 4 (33.3%) had partial response, 1 (8.3%) had a moderate response, 1 (8.3%) had stable disease, and 1 suffered progressive disease; the response rate was 75.0%. The 1‐, 2‐, 3‐, and 5‐year survival rates were 100.0%, 84.6%, 69.2%, and 38.5%, respectively, for patients with primary bone tumors and 83.3%, 16.7%, 0%, and 0%, respectively, for patients with metastatic bone tumors. The survival rates for patients with primary bone tumors were significantly better than for those with metastatic tumors.

CONCLUSIONS:

HIFU safely and noninvasively ablated malignant bone tumors and relieved pain. HIFU ablation should be further investigated, as it appears to be successful in the treatment of primary malignant bone tumors. Cancer 2010. © 2010 American Cancer Society.

Published: May 2010

BACKGROUND:

The combination of 3 cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and a tailored, extended irradiation schedule has been used to treat patients with early Hodgkin lymphoma (HL) in the authors' group since 1981. The randomized H97‐E trial (1997‐2004) was designed to assess the impact of a slightly reduced irradiation dose on the freedom from treatment failure (FFTF) rate.

METHODS:

Patients with supradiaphragmatic HL at clinical stages I and II who had ≤2 affected lymph node areas and a mediastinal mass ratio <0.33 were randomized into an experimental arm (EA) and a control arm (CA). Patients in the EA received 3 cycles of ABVD followed by irradiation at 36 grays (Gy) to initially involved sites and 24 Gy to adjacent sites, the upper infradiaphragmatic area, and the spleen. Patients in the CA received the same chemotherapy regimen and the same irradiation given at doses of 40 Gy and 30 Gy, respectively. Two hundred two patients who had received the CA treatment in 2 previous trials served as a historic control group (HCG).

RESULTS:

The 10‐year FFTF and overall survival rates were similar for the 89 patients in the EA (88.6% and 97.8%, respectively), for the 99 patients in the CA (92.6% and 95%, respectively), and for the 202 patients in the HCG (91.9% and 92.9%, respectively). Surprisingly, the 10‐year incidence of severe or fatal complications was nil in the EA but reached 15.5% in the CA (P < .003) and 11.1% in the HCG.

CONCLUSIONS:

Slightly lowering the radiation dose did not have an impact on the excellent cure rate among patients with early HL but significantly reduced the rate of long‐term, radiation‐induced complications. Cancer 2010. © 2010 American Cancer Society.
Far‐Infrared Spectra of Yttrium‐Doped Gold Clusters AunY (n=1–9)

Published: May 2010

The geometric, spectroscopic, and electronic properties of neutral yttrium‐doped gold clusters AunY (n=1–9) are studied by far‐infrared multiple photon dissociation (FIR‐MPD) spectroscopy and quantum chemical calculations. Comparison of the observed and calculated vibrational spectra allows the structures of the isomers present in the molecular beam to be determined. Most of the isomers for which the IR spectra agree best with experiment are calculated to be the energetically most stable ones. Attachment of xenon to the AunY cluster can cause changes in the IR spectra, which involve band shifts and band splittings. In some cases symmetry changes, as a result of the attachment of xenon atoms, were also observed. All the AunY clusters considered prefer a low spin state. In contrast to pure gold clusters, which exhibit exclusively planar lowest‐energy structures for small sizes, several of the studied species are three‐dimensional. This is particularly the case for Au4Y and Au9Y, while for some other sizes (n=5, 8) the 3D structures have an energy similar to that of their 2D counterparts. Several of the lowest‐energy structures are quasi‐2D, that is, slightly distorted from planar shapes. For all the studied species the Y atom prefers high coordination, which is different from other metal dopants in gold clusters.

The dumbbell‐like calcium carbonate (CaCO3) crystals were synthesized in the presence of trisodium citrate. Different morphologies were obtained by changing the reaction temperature and the trisodium citrate concentration. The obtained samples were characterized by means of X‐ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the morphology of CaCO3 crystals was markedly affected by the reaction temperature and citrate anion concentration. The possible growth mechanism of CaCO3 crystals was proposed. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Aqueous phase reforming of sorbitol over Pt supported on an alumina catalyst is investigated, in order to identify the intermediates involved in the transformation of the initial feed. Parameters such as the sorbitol feed rate and temperature are studied. To identify the intermediates, an approach based on analysis of the gas and liquid phases as well as the total carbon content was developed. According to analysis by gas chromatography combined with mass spectrometry of volatile substances collected with solid‐phase microextraction, over 260 compounds are involved in the transformation of sorbitol. Of these, 50 of the major products are identified with high reliability. It is shown that a great variety of compounds, bearing different functionalities, form part of the reaction network. The formation of the majority of identified compounds is explained and a reaction network for the formation of sorbitol and intermediate molecules transformation is proposed.

Published: May 2010

Paper wastes are used for the production of gaseous fuels over supported metal catalysts. The gasification of the nonrecyclable paper wastes, such as shredded documents and paper sludge, is carried out in high‐temperature liquid water. The order of the catalytic activity for the gasification is found to be ruthenium>rhodium≫platinum≫palladium. A charcoal‐supported ruthenium catalyst (Ru/C) is the most effective for the gasification of paper and cellulose. Paper wastes are gasified to a limited degree (32.6 carbon %) for 30 min in water at 523 K to produce methane and carbon dioxide, with a small amount of hydrogen. At 573 K, more complete gasification with almost 100 carbon % is achieved within 10 min in water. At 523 K, the gas yield of paper gasification over Ru/C is higher than that of cellulose powder. The gas yields are increased by ball‐milling treatment of the recycled paper and cellulose powder. Printed paper wastes are also gasified at 523 K in water.
Arterial and venous vessels are required for modulating developmental relocalization and laterality of the interrenal tissue in zebrafish

Published: May 2010

During zebrafish embryogenesis, the endothelium signals to emergent bilateral interrenal primordia to converge toward the midline, yet the merged interrenal tissue has been found to be situated lateral to the midline. We show in this study that bilateral interrenal tissue clusters fused at the central midline, before relocating laterally to be juxtaposed between the dorsal aorta and the posterior cardinal vein. In ets1b morphants where the midtrunk vasculature failed to assemble, various degrees of interrenal fusion defects were displayed, and the interrenal laterality was lost. As either arterial or venous endothelium was specifically reduced, the interrenal tissue was defective in its relocalization and laterality, yet remained closely associated with the malformed vasculature. Our results showed evidence to support that assembly of the axial artery and vein, and its resulting vascular topology at the midtrunk, is required for patterning relocalization and laterality of the interrenal tissue after the initial medial fusion.

Identification of genes expressed by zebrafish oligodendrocytes using a differential microarray screen
Authors: Takada Norio , Appel Bruce
Published: May 2010

Myelination of central nervous system axons requires that oligodendrocytes extend multiple membrane processes that specifically recognize and wrap axons, which is followed by expression of proteins necessary for formation of myelin sheaths. To identify new genes that might be important for myelination, we used microarrays to analyze the expression profiles of cells sorted from transgenic zebrafish embryos and larvae under conditions that permitted or blocked oligodendrocyte development. Here, we describe eight genes that have not been previously implicated in oligodendrocyte development. Among the predicted functions of proteins encoded by these genes are lipid sensing, cell–cell junction formation, cytoskeleton regulation, and intracellular signaling. The predicted functions raise the possibility that these genes are involved in multiple cellular events during oligodendrocyte differentiation and myelin formation.

Influence of black carbon and chemical planarity on bioavailability of sediment-associated contaminants

Published: May 2010

Black carbon (BC) and chemical properties may play a significant role in defining the bioavailability of hydrophobic organic compounds (HOCs) in sediment. In the current study, bioavailability of four HOCs with differing planarity was determined in sediments amended with two types of BC (soot and charcoal) at different concentrations by matrix solid-phase microextraction (matrix-SPME) and bioaccumulation testing using the freshwater oligochaete Lumbriculus variegatus. Furthermore, the applicability of the matrix-SPME method to bioavailability estimation in BC-amended sediment was tested. The charcoal treatment significantly reduced the bioaccumulation of the planar compounds (3,3′,4,4′-tetrachlorobiphenyl and benzo[a]pyrene) in L. variegatus, and the matrix-SPME method showed a similar trend as contaminant bioaccumulation in L. variegatus. Conversely, manipulation of sediment with soot had no effect or slightly increased bioavailability of the planar compounds in both bioaccumulation and matrix-SPME tests. Little if any affect was noted in bioavailability of the nonplanar compounds (2,2′,4,4′,5,5′-hexachlorobiphenyl and permethrin) with the soot and charcoal amendments. Results showed that the role of BC in defining bioavailability of HOCs depends not only on the type and concentrations of BC present, but also the planarity of the HOCs. Environ. Toxicol.

A closer look at bioaccumulation of petroleum hydrocarbon mixtures in aquatic worms
Authors: Muijs Barry , Jonker Michiel T.O.
Published: May 2010

Petroleum hydrocarbons (oils) are ubiquitous in the aquatic environment, and adequate risk assessment is thus essential. Bioaccumulation plays a key role in risk assessment, but the current knowledge on bioaccumulation of oils is limited. Therefore, this process was studied in detail, using the aquatic worm, Lumbriculus variegatus, and 14 field-contaminated sediments. The main focus during the present study was on uptake kinetics, the relationship between oil boiling point fraction and uptake, and effects of sediment characteristics. Uptake kinetics became slower with increasing boiling point fraction, but 70 to 90% of the equilibrium situation was reached within the standard exposure duration of 28 d. Worms accumulated sedimentary petroleum hydrocarbons in the range of C10 to C34, a range much wider than expected. Biota-to-sediment accumulation factors (BSAFs) for separate boiling point fractions were constant and around the proposed value of 1 to 2 up to C22, but gradually decreased beyond this point. The decrease was probably caused by a combination of nonequilibrium conditions and enhanced sorption of higher boiling point fractions to sediments; the latter possibly due to the presence of strongly sorbing separate oil phases or black carbon. A negative relationship was observed between BSAF and oil concentration in sediment, which was explained by the presence of separate oil phases at high oil concentrations. These strongly sorbing phases may limit their own availability, particularly when being highly weathered; worms may also avoid them. The observed phenomena have obvious implications for bioaccumulation assessment of oils and suggest that the current risk assessment procedure for oils in sediments may lead to erroneous results.
