Published: March 2016

AbstractA sulfa‐Michael addition/formal [3+3] annulation cascade reaction between 1,4‐dithiane‐2,5‐diol and 1,2‐diaza‐1,3‐dienes by a one‐pot base‐catalysed strategy was developed. This metal‐free and odourless method provides a practical and facile approach to 1,4‐thiazines obtained in total atom economy and in quantitative yields. Furthermore, the synthesis could be scaled‐up to the gram scale.

Published: March 2016

BackgroundAn increasing number of radiologic exams are performed in the United States, but very few studies have examined the effects of maternal exposure to radiologic exams during the periconceptional period and birth defects.ObjectivesTo assess the association between maternal exposure to radiologic exams during the periconceptional period and 19 categories of birth defects using a large population‐based study of birth defects.MethodsWe studied 27,809 case mothers and 10,200 control mothers who participated in the National Birth Defects Prevention Study and delivered between 1997 and 2009. Maternal exposure to radiologic exams that delivered ionizing radiation to the urinary tract, lumbar spine, abdomen, or pelvis were identified based on the mother's report of type of radiologic exams, organ or body part scanned and the month during which the exam occurredResultsOverall, 0.9% of mothers reported exposure to one of these types of radiographic exams during the periconceptional period. We observed significant associations between maternal exposure during the first trimester and isolated Dandy‐Walker malformation (odds ratio = 7.7; 95% confidence interval, 1.8–33) and isolated d‐transposition of the great arteries (odds ratio = 3.8; 95% confidence interval, 1.4–10.3). However, the result for isolated Dandy‐Walker malformation was based on only two exposed cases.ConclusionThese results should be interpreted cautiously because multiple statistical tests were conducted and measurements of exposure were based on maternal report. However, our results may be useful for generating hypotheses for future studies. Birth Defects Research (Part A) 106:563–572, 2016. © 2016 Wiley Periodicals, Inc.

Published: March 2016

ABSTRACTA modified enzyme‐linked immunosorbent assay (ELISA) with nanomaterials is an effective and powerful method to amplify the signal and reduce the cost of detecting and measuring trace biomarkers or proteins. In this study, an ultra‐sensitive colorimetric immunoassay was designed, and its ability to detect influenza viruses using positively charged gold nanoparticles ((+)Au NPs) was assessed as a possible role for peroxidase‐mimic inorganic enzymes. This method detected influenza virus A (H1N1) with a linear range up to 10 pg mL−1 and clinically isolated influenza virus A (H3N2) up to 10 plaque forming units (PFU) mL−1, where its sensitivity improved to 500‐fold higher than that of commercial virus kits. The sensitivity of this proposed method was not declined even though in complex biological media in compared to conventional ELISA. These results revealed that the (+)AuNP‐based colorimetric immunoassay could be suitable for lab‐on‐a‐chip device and open new opportunities for clinical protein diagnostics. Biotechnol.

Evolutionary engineering of Geobacillus thermoglucosidasius for improved ethanol production
Authors: Zhou Jiewen , Wu Kang , Rao Christopher V. 
Published: March 2016

ABSTRACTThe ability to grow at high temperatures makes thermophiles attractive for many fermentation processes. In this work, we used evolutionary engineering to increase ethanol production in the thermophile Geobacillus thermoglucosidasius. This bacterium is a facultative anaerobe, grows at an optimal temperature of 60°C, and can ferment diverse carbohydrates. However, it natively performs mixed‐acid fermentation. To improve ethanol productivity, we first eliminated lactate and formate production in two strains of G. thermoglucosidasius, 95A1 and C56‐YS93. These deletion strains were generated by selection on spectinomycin, which represents, to the best of our knowledge, the first time this antibiotic has been shown to work with thermophiles. Both knockout strains, however, were unable to grow under microaerobic conditions. We were able to recover growth in G. thermoglucosidasius 95A1 by serial adaptation in the presence of acetic acid. The evolved 95A1 strain was able to efficiently produce ethanol during growth on glucose or cellobiose. Genome sequencing identified loss‐of‐function mutations in adenine phosphoribosyltransferase (aprt) and the stage III sporulation protein AA (spoIIIAA). Disruption of both genes improved ethanol production in the unadapted strains: however, the increase was significant only when aprt was deleted. In conclusion, we were able to engineer a strain of G. thermoglucosidasius to efficiently produce ethanol from glucose and cellobiose using a combination of metabolic engineering and evolutionary strategies. This work further establishes this thermophile as a platform organism for fuel and chemical production. Biotechnol. Bioeng. 2016;113: 2156–2167. © 2016 Wiley Periodicals, Inc.

Published: March 2016

AbstractThere have been dramatic changes in the staging and treatment of Hodgkin's lymphoma (HL) over the past 30 years. We undertook this study to determine if a stage migration had occurred and also examined if treatment associated with later years has improved survival. Patients with stage I‐IV HL between 1983 and 2011 were selected from the Surveillance, Epidemiology, and End Results database. Multivariable analysis (MVA) was performed using Cox proportional hazards modeling. The study cohort included 35,680 patients. The stage breakdown in 1983 according to A and B symptoms was follows: 18%, 21%, 12%, and 5% for stage IA, IIA, IIIA, and IVA disease, respectively, and 6%, 11%, 12%, and 15% for stage IB, IIB, IIIB, and IVB disease. The stage breakdown in 2011 according to A and B symptoms was follows: 9%, 29%, 10%, and 6% for stage IA, IIA, IIIA, and IVA disease, respectively, and 4%, 16%, 12%, and 13% for stage IB, IIB, IIIB, and IVB disease. The median follow‐up for the entire cohort is 6.1 years. On MVA, the HR for mortality of patients diagnosed in 2006 was 0.60 (95% Confidence Interval (CI): 0.52–0.70) compared to 1983. For stage I and II patients diagnosed in 2006 the HR was 0.62 (95% CI: 0.44–0.87) and 0.40 (95% CI: 0.30–0.55), respectively, compared to patients diagnosed in 1983. For stage III and IV patients diagnosed in 2006 the HR was 0.72 (95% CI: 0.53–0.98) and 0.74 (95% CI: 0.56–0.99), respectively, compared to patients diagnosed in 1983. This is the first study to demonstrate a significant stage migration in early stage Hodgkin's lymphoma. Furthermore, these results demonstrate an improvement in survival over time for patients with Hodgkin's lymphoma which was particularly notable for those with early stage disease.
Understanding the Influence of Key Ionic Liquid Properties on the Hydrolytic Activity of Thermomyces lanuginosus Lipase
Authors: Han Qi , Wang Xungai , Byrne Nolene 
Published: March 2016

AbstractIonic liquids (ILs) are solvents with numerous properties, which have been recently used for enzyme catalysis. In this work, five different ILs based on primary, tertiary, and quaternary ammonium cations coupled with mesylate and propionate anions were used as media for hydrolysis by the industrially relevant enzyme Thermomyces lanuginosus lipase (TLL). We correlated the TLL activity with various key IL and IL–water properties, including ion concentration, water activity (aw), kosmotropicity, hydrogen‐bond basicity (β), and pH. The ion concentration was associated with aw, and the molar ratio of water/IL 5:1 (aw≈0.6) was found to be the threshold for assured TLL activity. Triethylammonium mesylate was the best IL owing to its kosmotropicity and ideal intrinsic β. The pH of IL–water mixtures is a key parameter related to the conformational change of TLL. We demonstrated the pH effect of the IL–water mixtures can be overcome by buffering, and the buffered system displayed the greatest activity.
In Situ Loading of Drugs into Mesoporous Silica SBA‐15

Published: March 2016

AbstractIn a new strategy for loading drugs into mesoporous silica, a hydrophilic (heparin) or hydrophobic drug (ibuprofen) is encapsulated directly in a one‐pot synthesis by evaporation‐induced self‐assembly. In situ drug loading significantly cuts down the preparation time and dramatically increases the loaded amount and released fraction of the drug, and appropriate drug additives favor a mesoporous structure of the vessels. Drug loading was verified by FTIR spectroscopy and release tests, which revealed much longer release with a larger amount of heparin or ibuprofen compared to postloaded SBA‐15. Besides, the in vitro anticoagulation properties of the released heparin and the biocompatibility of the vessels were carefully assessed, including activated partial thromboplastin time, thrombin time, hemolysis, platelet adhesion experiments, and the morphologies of red blood cells. A concept of new drug‐release agents with soft core and hard shell is proposed and offers guidance for the design of novel drug‐delivery systems.
Rules of Macrocycle Topology: A [13]‐Macrodilactone Case Study

Published: March 2016

AbstractShape is an inherent trait of a molecule that dictates how it interacts with other molecules, either in binding events or intermolecular reactions. Large‐ring macrocyclic compounds in particular leverage their shape when they are selectively bound by biomolecules and also when they exhibit macrocyclic diastereoselectivity. Nonetheless, rules that link structural parameters to the conformation of a macrocycle are still rudimentary. Here we use a structural investigation of a family of [13]‐macrodilactones as a case study to develop rules that can be applied generally to macrocycles of different sizes and with a variety of functionality. A characteristic “ribbon” shape is adopted by the [13]‐macrodilactones in the absence of stereogenic centres, which exhibits planar chirality. When one stereogenic centre at key positions on the backbone is incorporated into the structure, the planar chirality is dictated by the configuration of the centre. In cases where two stereogenic centres are present, their relationships can either reinforce the characteristic ribbon shape or induce alternative shapes to be adopted. The rules established in the case study are then applied to the analysis of a structure of the natural product migrastatin. They lay the groundwork for the development of models to understand macrocycle‐biomolecule interactions and for the preparation of macrocycles with designed properties and activities.

AbstractThe vibrational spectrum of a six‐coordinate nitrosyl iron porphyrinate, monoclinic [Fe(TpFPP)(1‐MeIm)(NO)] (TpFPP=tetra‐para‐fluorophenylporphyrin; 1‐MeIm=1‐methylimidazole), has been studied by oriented single‐crystal nuclear resonance vibrational spectroscopy (NRVS). The crystal was oriented to give spectra perpendicular to the porphyrin plane and two in‐plane spectra perpendicular or parallel to the projection of the FeNO plane. These enable assignment of the FeNO bending and stretching modes. The measurements reveal that the two in‐plane spectra have substantial differences that result from the strongly bonded axial NO ligand. The direction of the in‐plane iron motion is found to be largely parallel and perpendicular to the projection of the bent FeNO on the porphyrin plane. The out‐of‐plane Fe‐N‐O stretching and bending modes are strongly mixed with each other, as well as with porphyrin ligand modes. The stretch is mixed with v50 as was also observed for dioxygen complexes. The frequency of the assigned stretching mode of eight Fe‐X‐O (X=N, C, and O) complexes is correlated with the Fe−XO bond lengths. The nature of highest frequency band at ≈560 cm−1 has also been examined in two additional new derivatives. Previously assigned as the Fe−NO stretch (by resonance Raman), it is better described as the bend, as the motion of the central nitrogen atom of the FeNO group is very large. There is significant mixing of this mode. The results emphasize the importance of mode mixing; the extent of mixing must be related to the peripheral phenyl substituents.

Published: March 2016

AbstractA photo‐induced carboxylation reaction of allylic C−H bonds of simple alkenes with CO2 is prompted by means of a ketone and a copper complex. The unique carboxylation reaction proceeds through a sequence of an endergonic photoreaction of ketones with alkenes forming homoallyl alcohol intermediates and a thermal copper‐catalyzed allyl transfer reaction from the homoallyl alcohols to CO2 through C−C bond cleavage.

AbstractThe terminal bromomethoxydiene (BMD) moiety of the polyhydroxylated chain present in phormidolides and oscillariolides has been synthesized for first time. Several strategies for the stereoselective synthesis of the 4‐bromo‐3‐methoxybut‐3‐en‐2‐ones are described. Furthermore, a preliminary study to successfully introduce the BMD within the polyol chain and the fatty acid allowed us to corroborate the end structure of the polyol.
