Published: August 2014

Background: Cyclic phosphatidic acid (cPA) is a naturally occurring phospholipid mediator with a unique cyclic phosphate ring at the sn-2 and sn-3 positions of its glycerol backbone. Natural cPA and its chemically stabilized cPA derivative, 2-carba-cPA (2ccPA), inhibit chronic and acute inflammation, and 2ccPA attenuates neuropathic pain. Osteoarthritis (OA) is a degenerative disease frequently associated with symptoms such as inflammation and joint pain. Because 2ccPA has obvious antinociceptive activity, we hypothesized that 2ccPA might relieve the pain caused by OA. We aimed to characterize the effects of 2ccPA on the pathogenesis of OA induced by total meniscectomy in the rabbit knee joint. Results: Intra-articular injection of 2ccPA (twice a week for 42 days) significantly reduced pain and articular swelling. Histopathology showed that 2ccPA suppressed cartilage degeneration in OA. We also examined the effects of 2ccPA on the inflammatory and catabolic responses of human OA synoviocytes and chondrosarcoma SW1353 cells in vitro. 2ccPA stimulated synthesis of hyaluronic acid and suppressed production of the metalloproteinases MMP-1, −3, and −13. However, it had no effect on the production of interleukin (IL)-6, an inflammatory cytokine. The suppressive effect of 2ccPA on MMP-1 and −3 production in synoviocytes and on MMP-13 production in SW1353 cells was not mediated by the lysophosphatidic acid receptor, LPA1 receptor (LPA1R). Conclusions: Our results suggest that 2ccPA significantly reduces the pain response to OA by inducing hyaluronic acid production and suppressing MMP-1, −3, and −13 production in synoviocytes and chondrocytes.

Abstract
Second-order rate constants for reactions of 2-chloro-4-nitrophenyl X-substituted-benzoates 1a–1j with a series of cyclic secondary amines in MeCN have been measured. Comparison of the kinetic results with those reported previously for the corresponding reactions carried out in H2O containing 20 mol % DMSO has revealed that amines are less reactive in MeCN. The Brønsted-type plot for the aminolysis of 2-chloro-4-nitrophenyl benzoate (1f) in MeCN is linear with βnuc = 0.64, which is in contrast to the curved Brønsted-type plot reported for the reaction performed in the H2O–DMSO misxture. The Hammett plot for the reactions of 1a–1j with piperidine consists of two intersecting straight lines while the Yukawa–Tsuno plot exhibits an excellent linear correlation with ρX = 1.22 and r = 0.60, indicating that the nonlinear Hammett plot is not due to a change in rate-determining step but is caused by stabilization of substrates possessing an electron-donating substituent through resonance interactions between the substituent and the carbonyl functionality. It has been concluded that medium change from the H2O–DMSO mixture to MeCN forces the aminolysis of 1a–1j to proceed through a concerted mechanism by destabilizing the zwitterionic tetrahedral intermediate (T±).
Platelet Mapping Assay Interference Due to Platelet Activation in Heparinized Samples
Authors: Nelles Nicole J. , Chandler Wayne L. 
Published: August 2014

Abstract

Objectives:
Thromboelastography Platelet Mapping (TEGPM) is an assay designed to detect platelet inhibition due to aspirin or clopidogrel-like drugs. The purpose of this study was to evaluate potential causes of error in the design or operation of the assay.

Methods:
We evaluated percent inhibition of platelets due to aspirin or clopidogrel using TEGPM, which measures clot viscoelastic maximum amplitude (MA) after activation with adenosine diphosphate (ADP) or arachidonic acid (AA) and subtraction of MA due to fibrin (MAFibrin).

Results:
MAFibrin measured in heparinized blood showed an unstable increasing pattern in 28% of samples (16 of 58). The platelet aggregation inhibitor eptifibatide corrected increasing MAFibrin in 14 of 16 cases, while the thrombin inhibitor argatroban corrected increasing MAFibrin in six of 16 cases, suggesting that unanticipated platelet activation/ aggregation was a more important cause of unstable rising MAFibrin than uninhibited thrombin. The unstable increased MAFibrin falsely increased percent ADP inhibition on average from 19% to 38% and percent AA inhibition from 29% to 58%. Heparinized samples showed platelet clumping and had procoagulant platelet microvesicle levels double those in citrate anticoagulant.

Conclusions:
Unanticipated platelet activation/aggregation occurring in the heparinized TEGPM samples lead to erroneous percent inhibition results.

Abstract
Selenium is an essential micro-element in animal diet due to its high antioxidative properties. As a part of selenocystein it is an important constituent of the glutathione peroxidase (GPx) enzyme, which has a big importance for cell protection from oxidative damage. The aim of the present work was the investigation of the selenopyran effect on the antioxidative state of the pig ovary. The experiment was conducted with 18 gilts of Danube white breed randomly divided into two groups between 120 - 228 days of age. The animals received equal basal diets without selenium additives. The experimental gilts were injected once per month intramuscularly with oil solution of preparation selenopyran (9-phenylsymmetrical octahydroselenoxanthene) ensured 0.1 mgSe/kg live weight. After slaughtering, the ovaries were used for histological analysis and estimation of the selenium content in ovarian tissue by the atomic absorption spectroscopy method. The GPx activity in ovary homogenates using the colorimetric assay kit (BioVision) was measured. The expression of γ-glutamyl transpeptidase (GGT) in ovaries by immunochistochemical method was estimated. The selenopyran treatment leads to significant (P<0.05) increase of the selenium level in blood and non-significant (P>0.05) in ovarian tissue. Enhancement of GPx activity in the ovaries of experimental group was observed (142.61±6.6 versus 122.28±3.4U/gP, P<0.05). The GGT expression in the ovarian cortex cells, follicular fluid and in the erythrocytes of ovarian blood vessels in treated gilts was an evidence of active transport of glutathione from blood to the ovary tissue. The selenopyran treatment promotes the increase of the GPx dependent antioxidative defense in ovary of growing gilts.
THE LEX REPETUNDARUM OF THE TABULA BEMBINA
Authors: Mattingly Harold 
Published: August 2014

Abstract
Ever since Mommsen’s magisterial 1863 edition, the extortion law of the Tabula Bembina has been seen as a law of Gaius Gracchus. Since Mommsen’s intervention, only Carcopino and myself have seriously challenged the consensus. However, the sources imply that Gaius proposed a lex iudiciaria, not an extortion law, and, further, the role of the iudices editicii and the probability that chapters from the Lex Repetundarum on the reward for successful prosecutors were repeated in the Lex Tarentina of 104/3 BC together suggest that Klenze was right after all in identifying the law as the law of C. Servilius Glaucia. Lucilius’ apparent connection of the fierce Lex Calpurnia with Q. Scaevola’s trial in 119 or 118 BC seems to be the clinching evidence.

Published: August 2014

Objectives. We examined associations between adolescent girls’ sexual identity and the gender of their sexual partners, on one hand, and their reports of sexual health behaviors and reproductive health outcomes, on the other. Methods. We analyzed weighted data from pooled Youth Risk Behavior Surveys (2005 and 2007) representative of 13 US jurisdictions, focusing on sexually experienced girls in 8th through 12th grade (weighted n = 6879.56). We used logistic regression with hierarchical linear modeling to examine the strength of associations between reports about sexual orientation and sexual and reproductive health. Results. Sexual minority girls consistently reported riskier behaviors than did other girls. Lesbian girls’ reports of risky sexual behaviors (e.g., sex under the influence of drugs or alcohol) and negative reproductive health outcomes (e.g., pregnancy) were similar to those of bisexual girls. Partner gender and sexual identity were similarly strong predictors of all of the sexual behaviors and reproductive health outcomes we examined. Conclusions. Many sexual minority girls, whether categorized according to sexual identity or partner gender, are vulnerable to sexual and reproductive health risks. Attention to these risks is needed to help sexual minority girls receive necessary services.
The Montana Radon Study: Social Marketing via Digital Signage Technology for Reaching Families in the Waiting Room
Authors: Larsson Laura S. 
Published: August 2014

Objectives. I tested a social marketing intervention delivered in health department waiting rooms via digital signage technology for increasing radon program participation among priority groups. Methods. I conducted a tri-county, community-based study over a 3-year period (2010–2013) in a high-radon state by using a quasi-experimental design. We collected survey data for eligible participants at the time of radon test kit purchase. Results. Radon program participation increased at the intervention site (t38 = 3.74; P = .001; 95% confidence interval [CI] = 4.8, 16.0) with an increase in renters (χ21,228 = 4.3; P = .039), Special Supplementary Nutrition Program for Women, Infants, and Children families (χ21,166 = 3.13; P = .077) and first-time testers (χ21,228 = 10.93; P = .001). Approximately one third (30.3%; n = 30) attributed participation in the radon program to viewing the intervention message. The intervention crossover was also successful with increased monthly kit sales (t37 = 2.69; P = .01; 95% CI = 1.20, 8.47) and increased households participating (t23 = 4.76; P < .001; 95% CI = 3.10, 7.88). Conclusions. A social marketing message was an effective population-based intervention for increasing radon program participation. The results prompted policy changes for Montana radon programming and adoption of digital signage technology by 2 health departments.
Antioxidant system in Uromastyx philbyi during hibernation and activity periods
Authors: Afifi Mohamed , Alkaladi Ali 
Published: August 2014

AbstractHibernation is an extreme physiological state characterized by profound decreases in oxidative metabolism and body temperature during bouts of prolonged torpor, interrupted by brief periods of arousal with sudden increases in oxidative metabolism, with alterations in antioxidant defenses. We monitored the activities of antioxidant enzymes and oxidative stress during hibernation and activity in Uromastyx philbyi. 20 animals were used, 10 of which were collected in the hibernation season (group I) and the other 10 collected during the active period (group II). Blood, liver, brown adipose tissue (BAT) and brain samples were used to determine free radical and antioxidant levels. The results indicated a significant decrease of free radicals and increase of vitamin C, especially in serum during hibernation. In contrast, during the active period free radicals, enzymatic antioxidants as glutathione peroxidase (GPX), glutathione reductase (GR), superoxide dismutase (SOD) and catalase (CAT) and non-enzymatic antioxidants as reduce glutathione (GSH) and vitamin E increased in all studied tissues. It can be concluded that Uromastyx philbyi has a strong antioxidant defense system that protects it from the injurious effects of free radicals either at the periods of arousal or during activity periods.

Published: August 2014

AbstractThe Growth Differentiation Factor-15 gene (GDF15) is a member of TGF-b superfamily and this cytokine family is considered to be a promising target for cancer therapy. The purpose of this study was to investigate the effect of tumor derived GDF15 on proliferation and radiosensitivity of breast cancer cells in vitro and in vivo. A mouse breast cancer LM2 cell line with stable transfection of full-length mouse GDF15 cDNA was established. Cell growth and proliferation was observed using WST assay and impedance-based method. Radiation induced GDF15 and TGF-b1 expression was determined by qRT-PCR. Radiosensitivity was measured by a colony formation assay in vitro and by a tumor growth delay assay in vivo. Cells with more than a 10-fold increase in GDF15 expression had a higher growth rate than parental control cells in vitro and in vivo. The radiation induced elevation of the expression of TGFb1 was reduced in GDF15 overexpressing cells. GDF15 may play a role in the radiation response of breast cancer cells by effecting cell survival, inhibiting radiation-induced cell death, and inhibiting the TGF-b1 related cytotoxic action.

Authors: Belotindos Lawrence , Lazaro Jonathan , Villanueva Marvin , Mingala Claro 
Published: August 2014

AbstractTheileriosis is a tick-borne disease of domestic and wild animals that cause devastating economic loss in livestock in tropical and subtropical regions. Theileriosis is not yet documented in the Philippines as compared to babesiosis and anaplasmosis which are considered major tick-borne diseases that infect livestock in the country and contribute major losses to the livestock industry. The study was aimed to detect Theileria sp. at genus level in blood samples of cattle using polymerase chain reaction (PCR) assay. Specifically, it determined the phylogenetic relationship of Theileria species affecting cattle in the Philippines to other Theileria sp. registered in the GenBank. A total of 292 blood samples of cattle that were collected from various provinces were used. Theileria sp. was detected in 43/292 from the cattle blood samples using PCR assay targeting the major piroplasm surface protein (MPSP) gene. DNA sequence showed high similarity (90–99%) among the reported Theileria sp. isolates in the GenBank and the Philippine isolates of Theileria. Phylogenetic tree construction using nucleotide sequence classified the Philippine isolates of Theileria as benign. However, nucleotide polymorphism was observed in the new isolate based on nucleotide sequence alignment. It revealed that the new isolate can be a new species of Theileria.

Published: August 2014

AbstractAcanthamoeba are widespread free-living amoebae which may cause granulomatous amoebic encephalitis (GAE), keratitis, skin ulcerations and disseminated tissue infection. An important diagnostic and prognostic factor for the treatment of infection is a quick and correct diagnosis of amoebae strains. The aim of our study was to develop a rapid method for detection and identification of pathogenic Acanthamoeba spp. strains from diagnostic material collected from water. In this study we analysed five amplification-based genetic markers (Aca 16S, Ac6/210, GP, JDP, Nelson) used for identification of pathogenic Acanthamoeba spp. strains isolated in water sources in Poland, Iceland and Sweden. Our results demonstrated the presence of pathogenic Acanthamoeba strains in tap water. PCR assay appeared to be a more rapid and sensitive method to detect the presence of amoebae than the limited conventional techniques. Based on our observations, we can confirm that the use of four out of five genetic markers (Aca 16S, Ac 6/210, JDP, GP, Nelson) may be helpful in identification of Acanthamoeba spp. strains, but only one Aca 16S primer pair is a highly specific marker that distinguishes between pathogenic strains of Acanthamoeba and other free-living amoeba families.
The helminth fauna study of European common brown frog (Rana temporaria Linnaeus, 1758) in the Volga basin
Authors: Chikhlyaev Igor , Ruchin Alexander 
Published: August 2014

AbstractIn this paper we considered information on the helminth fauna of the European common brown frog (Rana temporaria Linnaeus, 1758) from 10 regions of the Volga basin. This study includes consolidated data of different authors over the last 30 years, supplemented by the results of our own research. There are reliably known finds of 29 species of helminths: Monogenea — 1, Trematoda — 21, Nematoda — 7. Trematodes Gorgodera asiatica Pigulevsky, 1945, Paralepoderma cloacicola (Luhe, 1909), mtc. and nematodes Icosiella neglecta (Diesing, 1851) were observed for the first time in a given host on the territory of Russia and the Volga Basin. Six species of worms make the basis of helminth fauna: nematodes Rhabdias bufonis, Oswaldocruzia filiformis, Neoxysomatium brevicaudatum and Cosmocerca ornata, trematode Haplometra cylindracea and monogenea Polystoma integerrimum. These six species are the most common and widespread parasites of the brown frog. For each species of helminths there is the following information included: taxonomic position, localization, area of detection, biology, definitive hosts, geographic distribution, the degree of host-specificity.
Monogenean parasites from fishes of the Vaal Dam, Gauteng Province, South Africa II. New locality records

Published: August 2014

AbstractBaseline information on parasitic infections, including monogenean infections on wild fishes, may aid in implementation of proactive measures as opposed to reactive research aimed at crisis control with reference to future aquaculture applications. The aim of this project was to examine the freshwater monogenean fauna of the Vaal Dam, Vaal River system, South Africa. This short communication reports on infection statistics for monogenean species, some representing new locality records. Parasites were collected from host species other than Labeo spp. from the Vaal Dam, during a summer (January 2010) survey. Fish collected using gill nets of varying mesh sizes were weighed and measured. Mucous smears were prepared from the skin and fins with the aid of microscope slides. Fish were killed humanely by severing the spinal cord behind the head. Gills were carefully removed and divided into areas which were separately scraped to investigate potential parasite site preference. The areas examined were dorsal, median and ventral positions on both the anterior and posterior hemibranch. Both mucous smears and gill scrapings were examined with the aid of a stereo microscope. More parasites were collected from the first or second gill arches, the medial position on the gill, and the anterior hemibranch. Preference for either left or right gill set was inconclusive. Spatial distribution of parasites is thought to result from water flow over the gills during respiration. This paper reports a new locality record for the following monogenean species: Quadriacanthus aegypticus, Dactylogyrus extensus, Dactylogyrus minitus, Gyrodactylus kherulensis and Dactylogyrus lamellatus.
Simha-Somcynsky Equation of State Modeling of the PVT Behavior of PP/Clay-Nanocomposite/CO2 Mixtures
Authors: Hasan M. M. , Park C. B. 
Published: August 2014

Abstract
The Pressure-Volume-Temperature (PVT) property of polymer nanocomposite (PNC)/gas solutions is an important fundamental property in the foaming of PNC. However, accurate data have not yet been reported. We examined the PVT behaviors of polypropylene (PP) and PP/organoclay polymer nanocomposite (PP-PNC) by monitoring the swelling changes of the polymer melt in supercritical carbon dioxide (scCO2). A model was adopted that describes the PVT behaviors of PP-PNC with and without dissolved gas. Based on the model, a PNC consists of two sections: a hard section (a nanoparticle surrounded by solidified polymer) and a soft section (neat polymer). It was observed that an infusion of nanoparticles decreased the swelling. It seems that the hard section had a minimal free volume in which to dissolve the blowing agents, and that the number of hard sections increased with the infusion of nanoparticles. As a result, the total gas absorption capacity of the system decreased, and consequently, the swelling also decreased.
Close- and Distant-Reading Modernism:
Authors: Drouin Jeffrey 
Published: August 2014

ABSTRACT
The digital humanities tends either to distant-read enormous data sets or to microanalyze the linguistic features of single works. “Big data” projects use software to visualize massive data sets of publishing information containing millions of volumes, revealing historic patterns that would be unobtainable by scholars. The main weakness of big data methodologies is their inability to read the works. The microscopic approach of text mining presents similar benefits and drawbacks. This article finds a middle ground by using these two techniques to read the September 1918 Little Review, examining the combined use of human markup and automated statistical techniques.
