BACKGROUND: Gpr151 is an orphan GPCR whose function is unknown. The restricted pattern of neuronal expression in the habenula, dorsal horn of the spinal cord and dorsal root ganglion plus homology with the galanin family of receptors imply a role in nociception. RESULTS: Real-time quantitative RT-PCR demonstrated a 49.9±2.9 fold highly significant (P<0.001) increase in Gpr151 mRNA expression in the dorsal root ganglion 7days after the spared nerve injury model of neuropathic pain...

We have performed non-equilibrium molecular dynamics simulations of various TiO2/water interfaces at ambient temperature in presence of oscillating electric fields in frequency range 20-100 GHz and RMS intensities 0.05-0.25 V/Å. Although the externally applied fields are by one order of magnitude lower than the intrinsic electric field present on the interfaces (∼1.5-4.5 V/Å), significant non-thermal coupling of rotational and translational motion of water molecules was clearly observed. Enhancement of the motion, manifested by increase of diffusivity, was detected in the first hydration layer, which is known to be heavily confined by adsorption to the TiO2 surface...

Given the fundamental role of water in governing the biochemistry of enzymes, and in regulating their wider biological activity (e.g., by local water concentration surrounding biomolecules), the influence of extraneous electric and electromagnetic (e/m) fields thereon is of central relevance to biophysics and, more widely, biology. With the increase in levels of local and atmospheric microwave-frequency radiation present in modern life, as well as other electric-field exposure, the impact upon hydration-water layers surrounding proteins, and biomolecules generally, becomes a particularly pertinent issue...

Water is fundamental to the biochemistry of enzymes. It is well known that without a minimum amount of water, enzymes are not biologically active. Bare minimal solvation for biological function corresponds to about a single layer of water covering enzymes' surfaces. Many contradictory studies on protein-hydration-water-coupled dynamics have been published in recent decades. Following prevailing wisdom, a dynamical crossover in hydration water (at around 220 K for hydrated lysozymes) can trigger larger-amplitude motions of the protein, activating, in turn, biological functions...

OBJECTIVE: Behavioural changes are an important part of amyotrophic lateral sclerosis (ALS). However, most tools do not account for the influence of motor impairment. Furthermore, they do not fully measure the broad range of behavioural changes specific to ALS. This study aimed to develop and validate an ALS specific behavioural inventory, the Beaumont Behavioural Inventory (BBI). METHODS: The BBI was validated in a cohort of ALS patients (n = 85) and 78 age-, gender-, and education-matched controls...

The majority of research on savanna vegetation dynamics has focused on the coexistence of woody and herbaceous vegetation. Interactions among woody plants in savannas are relatively poorly understood. We present data from a 10-year longitudinal study of spatially explicit growth patterns of woody vegetation in an East African savanna following exclusion of large herbivores and in the absence of fire. We examined plant spatial patterns and quantified the degree of competition among woody individuals. Woody plants in this semi-arid savanna exhibit strongly clumped spatial distributions at scales of 1 - 5 m...

A concerted effort to sequence matched primary and metastatic tumours is vastly improving our ability to understand metastasis in humans. Compelling evidence has emerged that supports the existence of diverse and surprising metastatic patterns. Enhancing these efforts is a new class of algorithms that facilitate high-resolution subclonal modelling of metastatic spread. Here we summarise how subclonal models of metastasis are influencing the metastatic paradigm.

OBJECTIVE: Failed attempts at peripheral i.v. cannula (PIVC) insertion in the ED are common. The psychological, physical and economic impact of these failures is significant. We sought to explore whether clinicians of differing experience levels can predict their own likelihood (clinician 'gestalt') of first-time cannula insertion success on any given patient. METHODS: Data analyses from a prospective self-reported study assessing risk factors for first-time insertion success in a tertiary adult ED...

INTRODUCTION: Spinal metastases secondary to renal cell carcinoma are associated with significant intra-operative blood loss. Our aim was to assess if embolisation reduced the intra-operative blood loss and transfusion requirement. METHODS: We performed a retrospective cohort study of 25 patients undergoing surgery between 2003 and 2011. RESULTS: 14 underwent pre-operative embolisation; 11 did not. There was no significant difference in intra-operative blood loss, 1336 ml vs 1492 ml in the non-embolised (p value = 0...

REVIEW
Ryan Stuchbery, Patrick J McCoy, Christopher M Hovens, Niall M Corcoran
The accumulation of high concentrations of signalling androgens within prostate tumours that progress despite use of androgen-deprivation therapy is a clinically important mechanism of the development of castration-resistant prostate cancer. In the past 5 years, data from a number of studies have increased our understanding of the enzymes and substrates involved in intratumoural androgen biosynthesis, and have implicated three competing pathways, which are likely to account for these observations. These pathways ('canonical', 'backdoor' and '5α-dione'), which can all ultimately generate the potent signalling androgen, dihydrotestosterone, involve many of the same enzymes, but differ in terms of substrate preference, reaction sequence and the organs and tissues in which they occur...

Fanconi anemia (FA) is a genetic disease characterized by bone marrow failure and increased cancer risk. The FA proteins function primarily in DNA interstrand crosslink (ICL) repair. Here, we have examined the role of the PTEN phosphatase in this process. We have established that PTEN-deficient cells, like FA cells, exhibit increased cytotoxicity, chromosome structural aberrations, and error-prone mutagenic DNA repair following exposure to ICL-inducing agents. The increased ICL sensitivity of PTEN-deficient cells is caused, in part, by elevated PLK1 kinase-mediated phosphorylation of FANCM, constitutive FANCM polyubiquitination and degradation, and the consequent inefficient assembly of the FA core complex, FANCD2, and FANCI into DNA repair foci...
