The influence of anogenital injury on women's willingness to engage with the criminal justice process after rape.

Medical-legal-social science research has documented that nongenital and/or anogenital injuries play a significant role throughout the criminal justice system from victims reporting to judges determining the length of a sentence. What remains an open question is whether the documentation of anogenital injury influences women's willingness to engage in the criminal justice system. A sample of women age 21 years and older residing in an urban area were asked about willingness to report to police, file charges, and work with the courts to prosecute after rape.

Allosteric regulation and substrate activation in cytosolic nucleotidase II from Legionella pneumophila.

Unlabelled: Cytosolic nucleotidase II (cN-II) from Legionella pneumophila (Lp) catalyzes the hydrolysis of GMP and dGMP displaying sigmoidal curves, whereas catalysis of IMP hydrolysis displayed a biphasic curve in the initial rate versus substrate concentration plots. Allosteric modulators of mammalian cN-II did not activate LpcN-II although GTP, GDP and the substrate GMP were specific activators. Crystal structures of the tetrameric LpcN-II revealed an activator-binding site at the dimer interface.

The 12 item Social and Economic Conservatism Scale (SECS).

Recent years have seen a surge in psychological research on the relationship between political ideology (particularly conservatism) and cognition, affect, behaviour, and even biology. Despite this flurry of investigation, however, there is as yet no accepted, validated, and widely used multi-item scale of conservatism that is concise, that is modern in its conceptualisation, and that includes both social and economic conservatism subscales. In this paper the 12-Item Social and Economic Conservatism Scale (SECS) is proposed and validated to help fill this gap.

Repeated intermittent alcohol exposure during the third trimester-equivalent increases expression of the GABA(A) receptor δ subunit in cerebellar granule neurons and delays motor development in rats.

Exposure to ethanol (EtOH) during fetal development can lead to long-lasting alterations, including deficits in fine motor skills and motor learning. Studies suggest that these are, in part, a consequence of cerebellar damage. Cerebellar granule neurons (CGNs) are the gateway of information into the cerebellar cortex.

Gradient echo quantum memory in warm atomic vapor.

Gradient echo memory (GEM) is a protocol for storing optical quantum states of light in atomic ensembles. The primary motivation for such a technology is that quantum key distribution (QKD), which uses Heisenberg uncertainty to guarantee security of cryptographic keys, is limited in transmission distance. The development of a quantum repeater is a possible path to extend QKD range, but a repeater will need a quantum memory.

Structural and biochemical characterization of the bilin lyase CpcS from Thermosynechococcus elongatus.

Cyanobacterial phycobiliproteins have evolved to capture light energy over most of the visible spectrum due to their bilin chromophores, which are linear tetrapyrroles that have been covalently attached by enzymes called bilin lyases. We report here the crystal structure of a bilin lyase of the CpcS family from Thermosynechococcus elongatus (TeCpcS-III). TeCpcS-III is a 10-stranded β barrel with two alpha helices and belongs to the lipocalin structural family.

Insulin treatment modulates the host immune system to enhance Pseudomonas aeruginosa wound biofilms.

Diabetes affects 25.8 million people in the United States, or 8.3% of the population, and these numbers are even higher in developing countries.

Solution NMR structure of CD1104B from pathogenic Clostridium difficile reveals a distinct α-helical architecture and provides first structural representative of protein domain family PF14203.

A high-quality structure of the 68-residue protein CD1104B from Clostridium difficile strain 630 exhibits a distinct all α-helical fold. The structure presented here is the first representative of bacterial protein domain family PF14203 (currently 180 members) of unknown function (DUF4319) and reveals that the side-chains of the only two strictly conserved residues (Glu 8 and Lys 48) form a salt bridge. Moreover, these two residues are located in the vicinity of the largest surface cleft which is predicted to contribute to a surface area involved in protein-protein interactions.

Solution NMR structures provide first structural coverage of the large protein domain family PF08369 and complementary structural coverage of dark operative protochlorophyllide oxidoreductase complexes.

High-quality NMR structures of the C-terminal domain comprising residues 484-537 of the 537-residue protein Bacterial chlorophyll subunit B (BchB) from Chlorobium tepidum and residues 9-61 of 61-residue Asr4154 from Nostoc sp. (strain PCC 7120) exhibit a mixed α/β fold comprised of three α-helices and a small β-sheet packed against second α-helix. These two proteins share 29% sequence similarity and their structures are globally quite similar.

Pharmacometabonomics and personalized medicine.

Background: Pharmacometabonomics is a new branch of science, first described in 2006 and defined as 'the prediction of the effects of a drug on the basis of a mathematical model of pre-dose metabolite profiles'. Pharmacometabonomics has been used to predict drug metabolism, pharmacokinetics (PK), drug safety and drug efficacy in both animals and humans and is complementary to both pharmacogenomics (PGx) and pharmacoproteomics.

Methods: A literature review using the search terms pharmacometabonomics, pharmacometabolomics, pharmaco-metabonomics, pharmaco-metabolomics and the singular form of all those terms was conducted in October 2012 using PubMed and Web of Science.

Crystal structures of malonyl-coenzyme A decarboxylase provide insights into its catalytic mechanism and disease-causing mutations.

Malonyl-coenzyme A decarboxylase (MCD) is found from bacteria to humans, has important roles in regulating fatty acid metabolism and food intake, and is an attractive target for drug discovery. We report here four crystal structures of MCD from human, Rhodopseudomonas palustris, Agrobacterium vitis, and Cupriavidus metallidurans at up to 2.3 Å resolution.

Adrenocortical carcinoma is a lynch syndrome-associated cancer.

Purpose: Adrenocortical carcinoma (ACC) is an endocrine malignancy with a poor prognosis. The association of adult-onset ACC with inherited cancer predisposition syndromes is poorly understood. Our study sought to define the prevalence of Lynch syndrome (LS) among patients with ACC.

PETINIA total phenytoin assay on the vista 1500 analyzer is not suitable for monitoring free phenytoin concentration if ultrafiltration is performed at room temperature.

Background: Phenytoin is a strongly protein-bound anticonvulsant requiring free drug monitoring for certain patients. Recently, free phenytoin assay on the TDx analyzer was discontinued by the Abbott Laboratories, but Roche Diagnostics has an assay for the determination of free phenytoin.

Methods: Because a clinical laboratory may not have an instrument for using Roche free phenytoin assay, we studied the possibility of determining free phenytoin using particle-enhanced turbidimetric inhibition immunoassay (PETINIA) total phenytoin assay on the Vista 1500 analyzer by comparing free phenytoin values obtained by Roche assay and Hitachi 917 analyzer with values obtained by using PETINIA assay.

Plate-based diversity subset screening: an efficient paradigm for high throughput screening of a large screening file.

The screening files of many large companies, including Pfizer, have grown considerably due to internal chemistry efforts, company mergers and acquisitions, external contracted synthesis, or compound purchase schemes. In order to screen the targets of interest in a cost-effective fashion, we devised an easy-to-assemble, plate-based diversity subset (PBDS) that represents almost the entire computed chemical space of the screening file whilst comprising only a fraction of the plates in the collection. In order to create this file, we developed new design principles for the quality assessment of screening plates: the Rule of 40 (Ro40) and a plate selection process that insured excellent coverage of both library chemistry and legacy chemistry space.

Report on the 10th anniversary of international drug discovery science and technology conference, 8 - 10 november 2012, nanjing, china.

The 10th Anniversary of International Drug Discovery Science and Technology (IDDST) Conference was held in Nanjing, China from 8 to 10 November 2012. The conference ran in parallel with the 2nd Annual Symposium of Drug Delivery Systems. Over 400 delegates from both conferences came together for the Opening Ceremony and Keynote Addresses but otherwise pursued separate paths in the huge facilities of the Nanjing International Expo Centre.

Moderate prenatal alcohol exposure reduces plasticity and alters NMDA receptor subunit composition in the dentate gyrus.

Although it is well documented that heavy consumption of alcohol during pregnancy impairs brain development, it remains controversial whether moderate consumption causes significant damage. Using a limited access, voluntary consumption paradigm, we recently demonstrated that moderate prenatal alcohol exposure (MPAE) is associated with dentate gyrus-dependent learning and memory deficits that are manifested in adulthood. Here, we identified a novel mechanism that may underlie this effect of MPAE.

Prevalence of germline TP53 mutations in a prospective series of unselected patients with adrenocortical carcinoma.

Purpose: Adrenocortical carcinoma (ACC) is a hallmark cancer in families with Li Fraumeni syndrome (LFS) caused by mutations in the TP53 gene. The prevalence of germline TP53 mutations in children diagnosed with ACC ranges from 50-97%. Although existing criteria advocate for TP53 testing in all patients with ACC regardless of age at diagnosis, the overall prevalence of germline mutations in patients diagnosed with ACC has not been well studied.

Solution NMR structure of the helicase associated domain BVU_0683(627-691) from Bacteroides vulgatus provides first structural coverage for protein domain family PF03457 and indicates domain binding to DNA.

A high-quality NMR structure of the helicase associated (HA) domain comprising residues 627-691 of the 753-residue protein BVU_0683 from Bacteroides vulgatus exhibits an all α-helical fold. The structure presented here is the first representative for the large protein domain family PF03457 (currently 742 members) of HA domains. Comparison with structurally similar proteins supports the hypothesis that HA domains bind to DNA and that binding specificity varies greatly within the family of HA domains constituting PF03457.

Shaping a screening file for maximal lead discovery efficiency and effectiveness: elimination of molecular redundancy.

High Throughput Screening (HTS) is a successful strategy for finding hits and leads that have the opportunity to be converted into drugs. In this paper we highlight novel computational methods used to select compounds to build a new screening file at Pfizer and the analytical methods we used to assess their quality. We also introduce the novel concept of molecular redundancy to help decide on the density of compounds required in any region of chemical space in order to be confident of running successful HTS campaigns.

Riding high on cloud 9.

Bath salts have become increasingly popular drugs of abuse. This has led to an increase in emergency department visits for patients with intoxication from these drugs. The literature indicates that bath salt intoxication can have significant physiological and psychiatric sequelae.

Structure of a specialized acyl carrier protein essential for lipid A biosynthesis with very long-chain fatty acids in open and closed conformations.

The solution nuclear magnetic resonance (NMR) structures and backbone (15)N dynamics of the specialized acyl carrier protein (ACP), RpAcpXL, from Rhodopseudomonas palustris, in both the apo form and holo form modified by covalent attachment of 4'-phosphopantetheine at S37, are virtually identical, monomeric, and correspond to the closed conformation. The structures have an extra α-helix compared to the archetypical ACP from Escherichia coli, which has four helices, resulting in a larger opening to the hydrophobic cavity. Chemical shift differences between apo- and holo-RpAcpXL indicated some differences in the hinge region between α2 and α3 and in the hydrophobic cavity environment, but corresponding changes in nuclear Overhauser effect cross-peak patterns were not detected.

Pharmacometabonomic characterization of xenobiotic and endogenous metabolic phenotypes that account for inter-individual variation in isoniazid-induced toxicological response.

An NMR-based pharmacometabonomic approach was applied to investigate inter-animal variation in response to isoniazid (INH; 200 and 400 mg/kg) in male Sprague-Dawley rats, alongside complementary clinical chemistry and histopathological analysis. Marked inter-animal variability in central nervous system (CNS) toxicity was identified following administration of a high dose of INH, which enabled characterization of CNS responders and CNS non-responders. High-resolution post-dose urinary ¹H NMR spectra were modeled both by their xenobiotic and endogenous metabolic information sets, enabling simultaneous identification of the differential metabolic fate of INH and its associated endogenous metabolic consequences in CNS responders and CNS non-responders.

Solution NMR and X-ray crystal structures of Pseudomonas syringae Pspto_3016 from protein domain family PF04237 (DUF419) adopt a "double wing" DNA binding motif.

The protein Pspto_3016 is a 117-residue member of the protein domain family PF04237 (DUF419), which is to date a functionally uncharacterized family of proteins. In this report, we describe the structure of Pspto_3016 from Pseudomonas syringae solved by both solution NMR and X-ray crystallography at 2.5 Å resolution.
