How did LUCA make a living? Chemiosmosis in the origin of life
Authors: Lane Nick , Allen John F. , Martin William
Published: January 2010

Despite thermodynamic, bioenergetic and phylogenetic failings, the 81‐year‐old concept of primordial soup remains central to mainstream thinking on the origin of life. But soup is homogeneous in pH and redox potential, and so has no capacity for energy coupling by chemiosmosis. Thermodynamic constraints make chemiosmosis strictly necessary for carbon and energy metabolism in all free‐living chemotrophs, and presumably the first free‐living cells too. Proton gradients form naturally at alkaline hydrothermal vents and are viewed as central to the origin of life. Here we consider how the earliest cells might have harnessed a geochemically created proton‐motive force and then learned to make their own, a transition that was necessary for their escape from the vents. Synthesis of ATP by chemiosmosis today involves generation of an ion gradient by means of vectorial electron transfer from a donor to an acceptor. We argue that the first donor was hydrogen and the first acceptor CO2.
One‐step RNA pathogen detection with reverse transcriptase activity of a mutated thermostable Thermus aquaticus DNA polymerase
Authors: Kranaster Ramon , Drum Matthias , Engel Nicole , Weidmann Manfred , Hufert Frank T. , Marx Andreas
Published: January 2010

We describe the cloning and characterization of a mutated thermostable DNA polymerase from Thermus aquaticus (Taq) that exhibits an increased reverse transcriptase activity and is therefore designated for one‐step PCR pathogen detection using established real‐time detection methods. We demonstrate that this Taq polymerase mutant (Taq M1) has similar PCR sensitivity and nuclease activity as the respective Taq wild‐type DNA polymerase. In addition, and in marked contrast to the wild‐type, Taq M1 exhibits a significantly increased reverse transcriptase activity especially at high temperatures (>60°C). RNA generally hosts highly stable secondary structure motifs, such as hairpins and G‐quadruplexes, which complicate, or in the worst case obviate, reverse transcription (RT). Thus, RT at high temperatures is desired to weaken or melt secondary structure motifs. To demonstrate the ability of Taq M1 for RNA detection of pathogens, we performed TaqMan probe‐based diagnostics of Dobrava viruses by one‐step RT‐PCR. We found similar detection sensitivities compared to commercially available RT‐PCR systems without further optimization of reaction parameters, thus making this enzyme highly suitable for any PCR probe‐based RNA detection method.
A rapid TRIzol‐based two‐step method for DNA‐free RNA extraction from Arabidopsis siliques and dry seeds
Authors: Meng Ling , Feldman Lewis
Published: January 2010

Extraction of high‐quality RNA from Arabidopsis seeds has been a challenge. Here we report a two‐step TRIzol‐based procedure for RNA extraction from Arabidopsis siliques and dry seeds. This procedure employs a modified, high pH (pH 9.5) extraction buffer. High pH plus the addition of either DTT or β‐mercaptoethanol in the extraction buffer effectively inhibits RNase activity during the extraction, and removes most polysaccharides, polyphenols and other insoluble material. TRIzol reagent was subsequently used to purify the RNA. Using this procedure we isolated high‐quality DNA‐free RNA samples without DNase I treatment from Arabidopsis seeds or siliques in less than 3 h.
Structural studies of SNARE complex and its interaction with complexin by molecular dynamics simulation
Authors: Ghahremanpour Mohammad Mehdi , Mehrnejad Faramarz , Moghaddam Majid Erfani
Published: January 2010

Since neurotransmitter releasing into the synaptic space delivers electrical signals from presynaptic neural cell to the postsynaptic cell, neurotransmitter secretion must be much orchestrated. Crowded intracellular vesicles involving neurotransmitters present a question of the how secretory vesicles fuse onto the plasma membrane in a fast synchronized fashion. Complexin is one of the most experimentally studied proteins that regulate assembly of fusogenic four‐helix SNARE complex to synchronized neurotransmitter secretion. We used MD simulation to investigate the interaction of complexin with the neural SNARE complex in detail. Our results show that the SNARE complex interacts with the complexin central helix by forming salt bridges and hydrogen bonds. Complexin also can interact with the Q‐SNARE complex instead of synaptobrevin to decrease the Q‐SNARE flexibility. The complexin alpha‐accessory helix and the C‐terminal region of synaptobrevin can interact with the same region of syntaxin. Although the alpha‐accessory helix aids the tight binding of the central helix to the SNARE complex, its proximity with synaptobrevin causes the destabilization of syntaxin and Sn1 helices. This study suggests that the alpha‐accessory helix of complexin can be an inhibiting factor for membrane fusion by competing with synaptobrevin for binding to the Q‐SNARE complex. © 2010 Wiley Periodicals, Inc.

Elderly POSSUM, a dedicated score for prediction of mortality and morbidity after major colorectal surgery in older patients
Authors: Tran Ba Loc P , Tezenas du Montcel S , Duron J J , Levard H , Suc B , Descottes B , Desrousseaux B , Hay J M
Published: January 2010

Background

Several scores have been developed to evaluate surgical unit mortality and morbidity. The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) and derivatives use preoperative and intraoperative factors, whereas the Surgical Risk Scale (SRS) and Association Française de Chirurgie (AFC) score use four simple factors. To allow for advanced age in patients undergoing colorectal surgery, a dedicated score—the Elderly (E) POSSUM—has been developed and its accuracy compared with these scores.

Methods

From 2002 to 2004, 1186 elderly patients, at least 65 years old, undergoing major colorectal surgery in France were enrolled. Accuracy was assessed by calculating the area under the receiver operating characteristic curve (AUC) (discrimination) and calibration.

Results

The mortality and morbidity rates were 9 and 41 per cent respectively. The E-POSSUM had both a good discrimination (AUC = 0·86) and good calibration (P = 0·178) in predicting mortality and a reasonable discrimination (AUC = 0·77) and good calibration (P = 0·166) in predicting morbidity. The E-POSSUM was significantly better at predicting mortality and morbidity than the AFC score (Pc = 0·014 and Pc < 0·001 respectively).

Conclusion

The E-POSSUM is a good tool for predicting mortality, and the only efficient scoring system for predicting morbidity after major colorectal surgery in the elderly.
Purification and characterization of Taq polymerase: A 9‐week biochemistry laboratory project for undergraduate students
Authors: Bellin Robert M. , Bruno Mary K. , Farrow Melissa A.
Published: January 2010

We have developed a 9‐week undergraduate laboratory series focused on the purification and characterization of Thermus aquaticus DNA polymerase (Taq). Our aim was to provide undergraduate biochemistry students with a full‐semester continuing project simulating a research‐like experience, while having each week's procedure focus on a single learning goal. The laboratory series has been taught for the past 7 years, and survey‐based assessment of the effectiveness of the laboratory series was completed during the 2006 and 2007 fall semesters. Statistical analysis of the survey results demonstrate that the laboratory series is very effective in teaching students the theory and practice of protein purification and analysis while also demonstrating positive results in more broad areas of scientific skill and knowledge. Amongst the findings, the largest reported increases in knowledge were related to students' understanding of how patent law relates to laboratory science, a topic of great importance to modern researchers that is readily discussed in relation to Taq polymerase. Overall, this laboratory series proves to be a very effective component in the curricula of undergraduate biology and chemistry majors and may be an appropriate laboratory experience for undergraduates.
Genomics and bioinformatics in undergraduate curricula: Contexts for hybrid laboratory/lecture courses for entering and advanced science students
Authors: Temple Louise , Cresawn Steven G. , Monroe Jonathan D.
Published: January 2010

Emerging interest in genomics in the scientific community prompted biologists at James Madison University to create two courses at different levels to modernize the biology curriculum. The courses are hybrids of classroom and laboratory experiences. An upper level class uses raw sequence of a genome (plasmid or virus) as the subject on which to base the experience of genomic analysis. Students also learn bioinformatics and software programs needed to support a project linking structure and function in proteins and showing evolutionary relatedness of similar genes. An optional entry‐level course taken in addition to the required first‐year curriculum and sponsored in part by the Howard Hughes Medical Institute, engages first year students in a primary research project. In the first semester, they isolate and characterize novel bacteriophages that infect soil bacteria. In the second semester, these young scientists annotate the genes on one or more of the unique viruses they discovered. These courses are demanding but exciting for both faculty and students and should be accessible to any interested faculty member.

Teacher strategies simulation by using fuzzy systems
Authors: Aguilar R. M. , Muñoz V. , Noda M. , Bruno A. , Moreno L.
Published: January 2010

Fuzzy system technologies are of emerging interest in the specification and implementation of complex systems. This article introduces fuzzy instructional planner, which models the tutor module in a intelligent tutorial system (ITS). The behaviour of this system is defined by strategies which adapt the learning process for individual students by applying appropriate pedagogical methodologies. For this reason, the purpose of a instructional planner is to mimic the behaviour of the teacher able to control learning process satisfactorily. The knowledge acquisition is based on the reasoning carried out by the teacher in a learning process. Usually, this information is obtained from human expert who supplied linguistic information. The capacity to use linguistic information is specific to fuzzy inference systems. © 2010 Wiley Periodicals, Inc.

Coalescence of Water Droplets in Crude Oil Emulsions: Analytical Solution
Authors: Bresciani A. E. , Alves R. M. B. , Nascimento C. A. O.
Published: January 2010

In petroleum refineries, water is used in desalting units to remove the salt contained in crude oil. Typically, 7 % of the volume of hot crude oil is water, forming a water‐and‐oil emulsion. The emulsion flows between two electrodes and is subjected to an electric field. The electrical forces promote the coalescence of small droplets of water dispersed in crude oil, and these form bigger droplets. This paper calculates the forces acting on the droplets, highlighting particularly the mechanisms proposed for droplet–droplet coalescence under the influence of an applied electric field. Moreover, a model is developed in order to calculate the displacement speed of the droplets and the time between droplet collisions. Thus, it is possible to simulate and optimize the process by changing the operational variables (temperature, electrical field, and water quantity). The main advantage of this study is to show that it is feasible to increase the volume of water recycled in desalting processes, thus reducing the use of freshwater and the generation of liquid effluents in refineries.
Synthesis of a Graphite Oxide Polyaniline Nano‐Composite by an Electrochemical Method
Authors: Rahimipour M. R. , Yazdani B.
Published: January 2010

In order to produce a polyaniline graphite oxide nano‐composite, electro‐polymerization of aniline was performed within the graphite oxide layers via electrochemical treatment of aniline‐intercalated graphite oxide in the supporting electrolyte. It was found that graphite oxide has special electro‐active properties. Therefore, electrochemical polymerization of aniline was performed on a Pt substrate in the presence of graphite oxide that had been dispersed in the electrolyte solution by the cyclic voltammetric method. Formation of polyaniline within the layers of graphite oxide occurred during electro‐polymerization. This mechanism affects the polyaniline morphology and leads to the formation of well‐defined concrete microstructures differing from the pure graphite oxide. Moreover, the results of the thermogravimetric analysis showed that graphite oxide and the polyaniline graphite oxide nano‐composite electrodeposited on the Pt substrate have different weight loss behaviors. This confirms that intercalation of the polyaniline improved the oxidation stability of graphite oxide, along with the fact that the polyaniline graphite oxide nano‐composite was successfully synthesized by an electrochemical method.
Sulfur Removal from Low‐Sulfur Gasoline and Diesel Fuel by Metal‐Organic Frameworks
Authors: Achmann S. , Hagen G. , Hämmerle M. , Malkowsky I. M. , Kiener C. , Moos R.
Published: January 2010

Several materials in the class of metal‐organic frameworks (MOF) were investigated to determine their sorption characteristics for sulfur compounds from fuels. The materials were tested using different model oils and common fuels such as low‐sulfur gasoline or diesel fuel at room temperature and ambient pressure. Thiophene and tetrahydrothiophene (THT) were chosen as model substances. Total‐sulfur concentrations in the model oils ranged from 30 mg/kg (S from thiophene) to 9 mg/kg (S from tetrahydrothiophene) as determined by elementary analysis. Initial sulfur contents of 8 mg/kg and 10 mg/kg were identified for low‐sulfur gasoline and for diesel fuel, respectively, by analysis of the common liquid fuels. Most of the MOF materials examined were not suitable for use as sulfur adsorbers. However, a high efficiency for sulfur removal from fuels and model oils was noticed for a special copper‐containing MOF (copper benzene‐1,3,5‐tricarboxylate, Cu‐BTC‐MOF). By use of this material, 78 wt % of the sulfur content was removed from thiophene containing model oils and an even higher decrease of up to 86 wt % was obtained for THT‐based model oils. Moreover, the sulfur content of low‐sulfur gasoline was reduced to 6.5 mg/kg, which represented a decrease of more than 22 %. The sulfur level in diesel fuel was reduced by an extent of 13 wt %. Time‐resolved measurements demonstrated that the sulfur‐sorption mainly occurs in the first 60 min after contact with the adsorbent, so that the total time span of the desulfurization process can be limited to 1 h. Therefore, this material seems to be highly suitable for sulfur reduction in commercial fuels in order to meet regulatory requirements and demands for automotive exhaust catalysis‐systems or exhaust gas sensors.
A New Heteroleptic Ruthenium(II) Polypyridyl Complex with Long‐Wavelength Absorption and High Singlet‐Oxygen Quantum Yield

Published: January 2010

Ruthenium(II) polypyridyl complexes with long‐wavelength absorption and high singlet‐oxygen quantum yield exhibit attractive potential in photodynamic therapy. A new heteroleptic RuII polypyridyl complex, [Ru(bpy)(dpb)(dppn)]2+ (bpy=2,2′‐bipyridine, dpb=2,3‐bis(2‐pyridyl)benzoquinoxaline, dppn=4,5,9,16‐tetraaza‐dibenzo[a,c]naphthacene), is reported, which exhibits a 1MLCT (MLCT: metal‐to‐ligand charge transfer) maximum as long as 548 nm and a singlet‐oxygen quantum yield as high as 0.43. Steady/transient absorption/emission spectra indicate that the lowest‐energy MLCT state localizes on the dpb ligand, whereas the high singlet‐oxygen quantum yield results from the relatively long 3MLCT(Ru→dpb) lifetime, which in turn is the result of the equilibrium between nearly isoenergetic excited states of 3MLCT(Ru→dpb) and 3ππ*(dppn). The dppn ligand also ensures a high binding affinity of the complex towards DNA. Thus, the combination of dpb and dppn gives the complex promising photodynamic activity, fully demonstrating the modularity and versatility of heteroleptic RuII complexes. In contrast, [Ru(bpy)2(dpb)]2+ shows a long‐wavelength 1MLCT maximum (551 nm) but a very low singlet‐oxygen quantum yield (0.22), and [Ru(bpy)2(dppn)]2+ shows a high singlet‐oxygen quantum yield (0.79) but a very short wavelength 1MLCT maximum (442 nm).
