We report a novel fabrication method of functionalised Bridged Rebar Graphene (BRG) onto newly designed nanostructured aptasensor for label free impedimetric sensing of pathogenic bacteria E. coli O78:K80:H11. The chemical facilitated unscrolling of MWCNT and subsequent bridging with terephthalaldehyde (TPA) to form 3D-hierarchical BRG nanoconstruct exhibited synergistic effect by combining enhanced electrical properties and facile chemical functionality for stable bio-interface. The bacteria-DNA interactions were captured on BRG nanostructured electrode by using specific anti-E...

A new series of the structural and functional models for the active site of [NiFe]-H2ases has been prepared by a simple and convenient synthetic route. Thus, treatment of diphosphines RN(PPh2)2 (1a, R = p-MeC6H4CH2; 1b, R = EtO2CCH2) with an equimolar NiCl2·6H2O, NiBr2·3H2O, and NiI2 in refluxing CH2Cl2/MeOH or EtOH gave the mononuclear Ni complexes RN(PPh2)2NiX2 (2a, R = p-MeC6H4CH2, X = Cl; 2b, R = EtO2CCH2, X = Cl; 3a, R = p-MeC6H4CH2, X = Br; 3b, R = EtO2CCH2, X = Br; 4a, R = p-MeC6H4CH2, X = I; 4b, R = EtO2CCH2, X = I) in 67-97% yields...

Two isostructural lanthanide (Ln) hybrid complexes co-bridged by organic oxalate and inorganic hypophosphite, [Ln(oxa)(H2PO2)(H2O)2] (oxa = oxalate; Ln = Gd (1), Dy (2)), were solvothermally prepared with the goal of elucidating the role of a hybrid framework in the generation of novel molecular magnetic materials. The title compounds feature a two dimensional (2D) hybrid layer. The Ln(III) ions are octa-coordinated with distorted square antiprism geometry. The adjacent Ln(III) ions are co-bridged by hypophosphite and one type of oxalate ligand to form 1D hybrid chains, which are further linked by a second type of oxalate ligand to generate the resulting 2D framework...

Molecular nitrogen (N2) is cheap and widely available, but its unreactive nature is a challenge when attempting to functionalize it under mild conditions with other widely available substrates (such as carbon monoxide, CO) to produce value-added compounds. Biological N2 fixation can do this, but the industrial Haber-Bosch process for ammonia production operates under harsh conditions (450 degrees Celsius and 300 bar), even though both processes are thought to involve multimetallic catalytic sites. And although molecular complexes capable of binding and even reducing N2 under mild conditions are known, with co-operativity between metal centres considered crucial for the N2 reduction step, the multimetallic species involved are usually not well defined, and further transformation of N2-binding complexes to achieve N-H or N-C bond formation is rare...

The advancement of gene-therapy-based approaches to treat heart disease represents a need for clinically-relevant animal models with characteristics equivalent to human pathologies. Rodent models of cardiac disease do not precisely reproduce heart failure phenotype and molecular defects. This has motivated researchers to use large animals whose heart size and physiological processes more similar and comparable to those of humans. Today, adeno-associated viruses (AAV)-based vectors are undoubtedly among the most promising DNA delivery vehicles...

OBJECTIVE: At the turn of the millennium, eating disorders (EDs) prevention was largely nonexistent. No program had reduced future onset of EDs in even a single trial, and most had not reduced ED symptoms. Sixteen years later, the ED prevention field has translated basic risk factor research into interventions, with demonstrated efficacy and effectiveness in reducing ED risk factors and symptoms, as well as future ED onset in some trials. This article reviews the aforementioned progress focusing on a model intervention (i...

David M Black
The power of Dante's Divine Comedy is unmistakable, but surprising in view of its theological structure and assumptions that are no longer current among most modern readers. This paper suggests that its power derives from the deep psychological truthfulness with which Dante deals with the painful personal crisis that underlies the poem and is his starting point. It attempts to clarify what may have constituted that crisis, and why the structure of the Comedy, and in particular its use of two guides, Virgil and Beatrice, who might be thought a somewhat incompatible pairing, point significantly to the nature of the solution Dante arrived at...

Protein phosphatase 5 (PP5), mainly localized in human brain, can dephosphorylate tau protein whose high level of phosphorylation is related to Alzheimer's disease. Similar to other protein phosphatases, PP5 has a conserved motif in the catalytic domain that contains two binding sites for manganese (Mn(2+) ) ions. Structural data indicate that two active site water molecules, one bridging the two Mn(2+) ions and the other terminally coordinated with one of the Mn(2+) ions (Mn1), are involved in catalysis. Recently, a density functional theory study revealed that the two water molecules can be both deprotonated to keep a neutral active site for catalysis...

Iva M Tolić
When a cell starts to divide, it forms a spindle, a micro-machine made of microtubules, which separates the duplicated chromosomes. The attachment of microtubules to chromosomes is mediated by kinetochores, protein complexes on the chromosome. Spindle microtubules can be divided into three major classes: kinetochore microtubules, which form k-fibers ending at the kinetochore; interpolar microtubules, which extend from the opposite sides of the spindle and interact in the middle; and astral microtubules, which extend towards the cell cortex...

The fission yeast Schizosaccharomyces pombe expresses the CCAAT-binding factor Php4 in response to iron deprivation. Php4 forms a transcription complex with Php2, Php3, and Php5 to repress the expression of iron proteins as a means to economize iron usage. Previous in vivo results demonstrate that the function and location of Php4 are regulated in an iron-dependent manner by the cytosolic CGFS type glutaredoxin Grx4. In this study, we aimed to biochemically define these protein-protein and protein-metal interactions...

Empathy plays a critical interpersonal and societal role, enabling sharing of experiences, needs, and desires between individuals and providing an emotional bridge that promotes pro-social behavior. This capacity requires an exquisite interplay of neural networks and enables us to perceive the emotions of others, resonate with them emotionally and cognitively, to take in the perspective of others, and to distinguish between our own and others' emotions. Studies show empathy declines during medical training...

DNA barcodes for species identification and the analysis of human mitochondrial variation have developed as independent fields even though both are based on sequences from animal mitochondria. This study finds questions within each field that can be addressed by reference to the other. DNA barcodes are based on a 648-bp segment of the mitochondrially encoded cytochrome oxidase I. From most species, this segment is the only sequence available. It is impossible to know whether it fairly represents overall mitochondrial variation...

This paper studies group selection for the partially linear model with a diverging number of parameters. We propose an adaptive group bridge method and study the consistency, convergence rate and asymptotic distribution of the global adaptive group bridge estimator under regularity conditions. Simulation studies and a real example show the finite sample performance of our method.

Pastoral psychologists have long tried to establish a working model that encompasses the seemingly conflicting disciplines of science and religion. Psychosynthesis, a transpersonal psychology and therapeutic approach, offers such a model of the human personality, in which the psychological and spiritual perspectives can converge. This article explores psychosynthesis psychology and therapy as a theoretical framework for pastoral psychology. Although psychosynthesis psychotherapy relies on an array of techniques, it fundamentally works with the clients' will while emphasizing, exploring, and cultivating their relationships on all levels-intrapersonal, interpersonal, and with the Higher Self...
