ObjectiveChronic stroke patients with severe hand weakness respond poorly to rehabilitation efforts. Here, we evaluated efficacy of daily brain–machine interface (BMI) training to increase the hypothesized beneficial effects of physiotherapy alone in patients with severe paresis in a double‐blind sham‐controlled design proof of concept study.MethodsThirty‐two chronic stroke patients with severe hand weakness were randomly assigned to 2 matched groups and participated in 17.8 ± 1.4 days of training rewarding desynchronization of ipsilesional oscillatory sensorimotor rhythms with contingent online movements of hand and arm orthoses (experimental group, n = 16). In the control group (sham group, n = 16), movements of the orthoses occurred randomly. Both groups received identical behavioral physiotherapy immediately following BMI training or the control intervention. Upper limb motor function scores, electromyography from arm and hand muscles, placebo–expectancy effects, and functional magnetic resonance imaging (fMRI) blood oxygenation level–dependent activity were assessed before and after intervention.ResultsA significant group × time interaction in upper limb (combined hand and modified arm) Fugl–Meyer assessment (cFMA) motor scores was found. cFMA scores improved more in the experimental than in the control group, presenting a significant improvement of cFMA scores (3.41 ± 0.563‐point difference, p = 0.018) reflecting a clinically meaningful change from no activity to some in paretic muscles. cFMA improvements in the experimental group correlated with changes in fMRI laterality index and with paretic hand electromyography activity. Placebo–expectancy scores were comparable for both groups.InterpretationThe addition of BMI training to behaviorally oriented physiotherapy can be used to induce functional improvements in motor function in chronic stroke patients without residual finger movements and may open a new door in stroke neurorehabilitation.

ObjectiveMicroRNAs (miRNAs) are single‐stranded, small noncoding RNAs that regulate gene expression. Because they are stable in serum, they are being developed as biomarkers for cancer and other diseases. In multiple sclerosis (MS), miRNAs have been studied in cell populations but not in the circulation. In MS, a major challenge is to develop immune biomarkers to monitor disease. We asked whether circulating miRNAs could be identified in MS and whether they are linked to disease stage and/or disability.MethodsA total of 368 miRNAs were measured in ethylenediaminetetraacetic acid plasma in 10 relapsing–remitting MS (RRMS) patients, 9 secondary progressive MS (SPMS) patients, and 9 healthy controls (HCs) using miRCURY LNA™ Universal RT microRNA polymerase chain reaction panels. Nineteen miRNAs from this discovery set were validated using qPCR on an independent set of 50 RRMS patients, 51 SPMS patients, and 32 HCs.ResultsWe found that circulating miRNAs are differentially expressed in RRMS and SPMS versus HCs and in RRMS versus SPMS. We also found miRNAs to be linked to Expanded Disability Status Scale (EDSS). hsa‐miR‐92a‐1* was identified in the largest number of comparisons. It was different in RRMS versus SPMS, and RRMS versus HCs, and showed an association with EDSS and disease duration. miR‐92 has target genes involved in cell cycle regulation and cell signaling. The let‐7 family of miRNAs differentiated SPMS from HCs and RRMS from SPMS. let‐7 miRNAs regulate stem cell differentiation and T cell activation, activate Toll‐like receptor 7, and are linked to neurodegeneration. hsa‐miR‐454 differentiated RRMS from SPMS, and hsa‐miR‐145 differentiated RRMS from HCs and RRMS from SPMS. Interestingly, the same circulating miRNAs (let‐7 and miR‐92) that were differentially expressed in RRMS versus SPMS also differentiated amyotrophic lateral sclerosis (ALS) from RRMS subjects, but were not different between SPMS and ALS, suggesting that similar processes may occur in SPMS and ALS.InterpretationOur results establish circulating miRNAs as a readily accessible blood biomarker to monitor disease in MS.

AbstractDie Modifizierung von Proteinen mit synthetischen Sonden kann in vielfältiger Weise zur Aufklärung und Beeinflussung von Proteinfunktionen in vitro, in lebenden Zellen oder in vivo genutzt werden. Wir stellen hier die jüngsten Fortschritte bei den Methoden zur chemischen Proteinmodifizierung und ihrer Anwendung beim Protein‐Engineering vor, wobei wir uns auf vier Strategien konzentrieren: 1) Biokonjugationsreaktionen von Aminosäuren an der Oberfläche natürlicher Proteine, hauptsächlich im Reagenzglas; 2) bioorthogonale Reaktionen von Proteinen mit nichtnatürlichen reaktiven Markergruppen; 3) Kupplung von Erkennungs‐ und reaktiven Regionen unter Verwendung eines Paars aus Enzym oder kurzem Peptid mit einem Sondenmarker zur Markierung natürlicher Aminosäuren 4) ligandendirigierte chemische Reaktionen zur selektiven Markierung endogener Proteine in lebenden Systemen. Zusammengenommen bieten diese Techniken ein nützliches Repertoire von Methoden zur Anwendung in der chemischen Biologie, wobei die drei letztgenannten auf unveränderte (lebende) Systeme anwendbar sind. Die organische Chemie zur Manipulation endogener Proteine ist zwar noch in einer frühen Phase, doch die nachfolgend beschriebenen Anwendungen sind ein lohnendes Ziel für Chemiker.

Abstract

Background
The oncological benefit of repeat hepatectomy for patients with recurrent colorectal metastases is not yet proven. This study assessed the value of repeat hepatectomy for these patients within current multidisciplinary treatment.

Methods
Consecutive patients treated by repeat hepatectomy for colorectal metastases between January 1990 and January 2010 were included. Patients undergoing two-stage hepatectomy were excluded. Postoperative outcome was analysed and compared with that of patients who had only a single hepatectomy.

Results
A total of 1036 patients underwent 1454 hepatectomies for colorectal metastases. Of these, 288 patients had 362 repeat hepatectomies for recurrent metastases. Some 225 patients (78·1 per cent) had two hepatectomies, 52 (18·1 per cent) had three hepatectomies, and 11 patients (3·8 per cent) had a fourth hepatectomy. Postoperative morbidity following repeat hepatectomy was similar to that after initial liver resection (27·1 per cent after first, 34·4 per cent after second and 33·3 per cent after third hepatectomy) (P = 0·069). The postoperative mortality rate was 3·1 per cent after repeat hepatectomy versus 1·6 per cent after first hepatectomy. Three- and 5-year overall survival rates following first hepatectomy in patients who underwent repeat hepatectomy were 76 and 54 per cent respectively, compared with 58 and 45 per cent in patients who had only one hepatectomy (P = 0·003). In multivariable analysis, repeat hepatectomy performed between 2000 and 2010 was the sole independent factor associated with longer overall survival.

Conclusion
Repeat hepatectomy for recurrent colorectal metastases offers long-term survival in selected patients.
Towards Squalamine Mimics: Synthesis and Antibacterial Activities of Head‐to‐Tail Dimeric SterolPolyamine Conjugates
Authors: Chen Wen‐Hua , Wennersten Christine , Moellering Robert C. , Regen Steven L. 
Published: March 2013

AbstractFour dimeric sterolpolyamine conjugates have been synthesized from the homo‐ and hetero‐connection of monomeric sterolpolyamine analogs in a head‐to‐tail manner. These dimeric conjugates show strong antibacterial activity against a broad spectrum of Gram‐positive bacteria, whereas their corresponding activities against Gram‐negative bacteria are relatively moderate. Though no significant difference was observed in the activities of these conjugates, cholic acid‐containing dimeric conjugates generally exhibit higher activities than the corresponding deoxycholic acid‐derived analogs. This is in contrast to the finding that a monomeric deoxycholic acid‐spermine conjugate was more active than the corresponding cholic acid‐derived analog.

Published: March 2013

AbstractDalmatian pyrethrum (Tanacetum cinerariifolium (Trevir.) Sch.Bip.) is a plant species endemic to the east Adriatic coast. The bioactive substance of Dalmatian pyrethrum is a natural insecticide, pyrethrin, a mixture of six active components (pyrethrins I and II, cinerins I and II, and jasmolins I and II). The insecticidal potential of pyrethrin was recognized decades ago, and dried and ground flowers have traditionally been used in Croatian agriculture and households.A total of 25 Dalmatian pyrethrum populations from Croatia were studied to determine the pyrethrin content and composition, and to identify distinct chemotypes. The total pyrethrin content ranged from 0.36 to 1.30% (dry flower weight; DW) and the pyrethrin I/pyrethrin II ratio ranged from 0.64 to 3.33%. The statistical analyses revealed that the correlations between the percentage of pyrethrin I and of all the other components were significant and negative. The total pyrethrin content was positively correlated with the percentage of pyrethrin I and negatively correlated with cinerin II. The multivariate analysis of the chemical variability enabled the identification of five chemotypes among 25 Dalmatian pyrethrum populations. The chemical characterization of indigenous Dalmatian pyrethrum populations may serve as a good background for future breeding and agricultural exploitation.

Published: March 2013

AbstractThe composition of 21 essential‐oil samples isolated from Helichrysum italicum collected in seven locations of Elba Island (Tuscany, Italy), characterized by different soil types, during three different periods (January, May, and October 2010) was determined by GC‐FID and GC/EI‐MS analyses. In total, 115 components were identified, representing 96.8–99.8% of the oil composition. The oils were characterized by a high content of oxygenated monoterpenes (38.6–62.7%), while monoterpene and sesquiterpene hydrocarbons accounted for 2.3–41.9 and 5.1–20.1% of the identified constituents, respectively. The main oxygenated derivatives were nerol (2.8–12.8%) and its ester derivative neryl acetate (5.6–45.9%). To compare the chemical variability of the species within Elba Island and between the island and other localities within the Mediterranean area, studied previously, multivariate statistical analysis was performed. The results obtained showed a difference in the composition of the essential oils of H. italicum from Elba Island, mainly due to the environment where the plant grows, and, in particular, to the soil type. These hypotheses were further confirmed by the comparison of these oils with essential oils obtained from H. italicum collected on other islands of the Tuscan archipelago.
Rh1/γ‐Al2O3 Single‐Atom Catalysis of O2 Activation and CO Oxidation: Mechanism, Effects of Hydration, Oxidation State, and Cluster Size
Authors: Ghosh Tushar K. , Nair Nisanth N. 
Published: March 2013

AbstractThe single‐atom catalysis of O2 activation and CO oxidation with Rh1 supported on γ‐Al2O3 is investigated here through ab initio molecular dynamics techniques. We scrutinize the molecular details of the mechanism for the full catalytic cycle that involves the oxidation of two CO molecules in succession. The effect of the surface hydration and oxidation state of Rh on the kinetics of O2 activation and CO oxidation is presented. We also report here the catalytic activity of experimentally intercepted RhI(CO)2 on γ‐Al2O3. Furthermore, we delineate the importance of single‐atom catalysis by comparing the performance of the Rh6/Al2O3 catalyst. A molecular level understanding of the differential reactivity on hydration, on oxidation, and of a larger Rh cluster size is reported.
Painting Anatase (TiO2) Nanocrystals on Long Nanofibers to Prepare Photocatalysts with Large Active Surface for Dye Degradation and Organic Synthesis

Published: March 2013

AbstractAnatase TiO2 nanocrystals were painted on H‐titanate nanofibers by using an aqueous solution of titanyl sulfate. The anatase nanocrystals were bonded solidly onto the titanate fibers through formation of coherent interfaces at which the oxygen atoms were shared by the nanocrystals and the fiber. This approach allowed us to create large anatase surfaces on the nanofibers, which are active in photocatalytic reactions. This method was also applied successfully to coat anatase nanocrystals on surfaces of fly ash and layered clay. The painted nanofibers exhibited a much higher catalytic activity for the photocatalytic degradation of sulforhodamine B and the selective oxidation of benzylamine to the corresponding imine (with a product selectivity >99 %) under UV irradiation than both the parent H‐titanate nanofibers and a commercial TiO2 powder, P25. We found that gold nanoparticles supported on H‐titanate nanofibers showed no catalytic activity for the reduction of nitrobenzene to azoxybenzene, whereas the gold nanoparticles supported on the painted nanofibers and P25 could efficiently reduce nitrobenzene to azoxybenzene as the sole product under visible light irradiation. These results were different from those from the reduction on the gold nanoparticles photocatalyst on ZrO2, in which the azoxybenzene was the intermediate and converted to azobenzene quickly. Evidently, the support materials significantly affect the product selectivity of the nitrobenzene reduction. Finally, the new photocatalysts could be easily dispersed into and separated from a liquid because of their fibril morphology, which is an important advantage for practical applications.

Published: March 2013

AbstractTwo benzodifuran (BDF)‐coupled spiropyran (SP) systems and their BDF reference compounds were obtained in good yields through Huisgen–Meldal–Sharpless “click” chemistry and then subjected to investigation of their electrochemical and photophysical properties. In both SP and merocyanine (MC) forms of the coupled molecules, the BDF‐based emission is quenched to around 1 % of the quantum yield of emission from the BDF reference compounds. Based on electrochemical data, this quenching is attributed to oxidative electron‐transfer quenching. Irradiation at 366 nm results in ring opening to the MC forms of the BDF‐coupled SP compounds and the SP reference compound with a quantum efficiency of about 50 %. The rate constants for the thermal ring closing are approximately 3.4×10−3 s−1. However, in the photostationary states the MC fractions of the coupled molecules are substantially lower than that of the reference SP compound, attributed to the observed acceleration of the ring‐closing reaction upon irradiation. As irradiation at 366 nm invariably also excites higher‐energy transitions of the BDF units in the coupled compounds, the ring‐opening reaction is accelerated relative to the SP reference, which results in lower MC fractions in the photostationary state. Reversible photochromism of these BDF‐coupled SP compounds renders them promising in the field of molecular switches.
