Phylogeography of western Pacific Leucetta ‘chagosensis’ (Porifera: Calcarea) from ribosomal DNA sequences: implications for population history and conservation of the Great Barrier Reef World Heritage Area (Australia)

Leucetta ‘chagosensis’ is a widespread calcareous sponge, occurring in shaded habitats of Indo‐Pacific coral reefs. In this study we explore relationships among 19 ribosomal DNA sequence types (the ITS1‐5.8S–ITS2 region plus flanking gene sequences) found among 54 individuals from 28 locations throughout the western Pacific, with focus on the Great Barrier Reef (GBR). Maximum parsimony analysis revealed phylogeographical structuring into four major clades (although not highly supported by bootstrap analysis) corresponding to the northern/central GBR with Guam and Taiwan, the southern GBR and subtropical regions south to Brisbane, Vanuatu and Indonesia. Subsequent nested clade analysis (NCA) confirmed this structure with a probability of > 95%. After NCA of geographical distances, a pattern of range expansion from the internal Indonesian clade was inferred at the total cladogram level, as the Indonesian clade was found to be the internal and therefore oldest clade. Two distinct clades were found on the GBR, which narrowly overlap geographically in a line approximately from the Whitsunday Islands to the northern Swain Reefs. At various clade levels, NCA inferred that the northern GBR clade was influenced by past fragmentation and contiguous range expansion events, presumably during/after sea level low stands in the Pleistocene, after which the northern GBR might have been recolonized from the Queensland Plateau in the Coral Sea. The southern GBR clade is most closely related to subtropical L. ‘chagosensis’, and we infer that the southern GBR probably was recolonized from there after sea level low stands, based on our NCA results and supported by oceanographic data. Our results have important implications for conservation and management of the GBR, as they highlight the importance of marginal transition zones in the generation and maintenance of species rich zones, such as the Great Barrier Reef World Heritage Area.
Periorbital dermatitis: Causes, differential diagnoses and therapy

Periorbital dermatitis is common and frequently difficult to treat. Patients with periorbital dermatitis often suffer severely because their disease is in such a visible location. Because of the variety of clinical appearance, the differential diagnostic considerations are often difficult. We examined the causes of periorbital dermatitis and compared the data of 88 patients from the Department of Dermatology, University Hospital Erlangen to those of the German IVDK (Information Network of the Departments of Dermatology). Between 1999 and 2004, predominant causes of periorbital dermatitis were allergic contact dermatitis (Erlangen 44 %, IVDK 32 %), atopic eczema (Erlangen 25 %, IVDK 14 %), airborne contact dermatitis (Erlangen 10 %, IVDK 2 %) and irritant contact dermatitis (Erlangen 9 %, IVDK 8 %). Less frequent causes for secondary eczematous periocular skin lesions were periorbital rosacea, allergic conjunctivitis or psoriasis vulgaris. Female gender, atopic skin diathesis and age of 40 years and older were identified as risk factors for periocular dermatitis. Common elicitors of periorbital allergic contact dermatitis were leave‐on cosmetic products (face cream, eye shadow) and eye drops with the usual allergens being fragrances, preservatives and drugs. Exact identification of relevant contact allergens and allergen elimination are essential for successful treatment. Calcineurin inhibitors are the first‐line therapy for facial atopic eczema. They may be also effective in periocular eczematous lesions of other origins although they are not approved for such use.
Circadian melatonin concentration rhythm is lost in pregnant women with altered blood pressure rhythm

We assessed the correlation between the rhythm of melatonin concentration and circadian blood pressure patterns in normal and hypertensive pregnancy. Ambulatory 24-h blood pressure and blood samples every 4 h were monitored in 16 primigravidae who had shown an abnormal circadian blood pressure pattern (eight pre-eclamptic and eight normotensive) in pregnancy and 6–12 months after pregnancy. The circadian rhythm was analyzed by chronobiological measures. Eight normotensive women with maintained blood pressure rhythm served as controls. During pregnancy, melatonin concentration was significantly higher in pre-eclamptic than in normotensive women (pre-eclampsia, 29.4±1.9 pg/ml, normotensin, altered rhythm, 15.6±2.1; controls, 22.7±1.8; p<0.001). This difference faded after pregnancy, owing to the fall observed in pre-eclampsia (11.8±3.2 pg/ml, 9.8±2.1, and 11.1±2.0, respectively; NS). The rhythm of melatonin concentration was lost in all pregnant women with loss of blood pressure rhythm. After pregnancy, normotensive women showed a reappearance of both melatonin and blood pressure rhythm, whereas pre-eclamptic women showed a reappearance of blood pressure but not melatonin rhythm. The loss of blood pressure rhythm in pregnancy is consistent with the loss of melatonin concentration rhythm. In pre-eclamptic women, the normalization of blood pressure rhythm, while melatonin rhythm remained altered, suggests a temporal or causal priority of circadian concentration of melatonin in the determination of blood pressure trend.
Human Leukocyte Antigens I and II Haplotypes Associated With Human Papillomavirus 16-Positive Invasive Cervical Cancer in Mexican Women

Infection with human papillomavirus (HPV), mainly HPV type 16, is the major etiologic factor associated with cervical cancer (CC), but HPV infection alone is not sufficient for progression of precursor lesions. Host genetic susceptibility may lead to abnormal immune response resulting from virus persistence. Several studies have suggested a possible association with specific human leukocyte antigen (HLA) class I and II alleles and CC, but results are not consistent. The association of genetic HLA class I (A and B) and HLA class II (DR*B1 and DQ*B1) haplotypes with HPV16-positive CC (n = 104) and base population controls (n = 104) was evaluated in this Mexican population study. Sequence-specific primer HLA genes were determined by polymerase chain reaction (PCR)-based methods in peripheral blood cell counts (PCR sequence-specific oligonucleotides). The cervical swabs of 208 women were tested for HPV16 by Hybrid Capture II. Allele and haplotype HLA frequencies, Hardy-Weinberg tests, and a haplotype homogeneity test were estimated using the Arlequin software v. 3.01. Odds ratio (OR) was calculated to compare cases and control women. Consistent associations across other studies in women with CC and infected by HPV16 were observed for HLA-DRB1*15 (OR, 3.9; 95% CI, 1.6-10.2) and the haplotype DRB1*15 DQB1*0602 (OR, 4.1; 95% CI, 1.4-12.7) compared with control women. The HLA-A2-B44-DR4-DQ*0302, HLA-A24-B35-DR16-DQ*0301, and HLA-A2-B40-DR4-DQ*0302 haplotypes showed a positive association with CC (OR, >1), whereas HLA-A2-B39-DR4-DQ*0302, HLA-A24-B35-DR4-DQ*0302, and HLA-A68-B40-DR4-DQ*0302 showed a negative association (OR, <1). These results support the hypothesis that some HLA class I and II haplotypes could be involved with susceptibility for developing CC.

Presence and expression of G2 cyclins in the coelenterate hydra.

In hydra all cell-cycle control occurs in the G2/M transition. Cyclins acting at this restriction point in the cell cycle belong to the cyclin A and B families. In agreement with this we isolated cDNAs coding for a cyclin A and a cyclin B from the multiheaded mutant of Chlorohydra viridissima and a cyclin B from Hydra vulgaris. The two B-type cyclins from hydra show 85.6% identity at the amino acid level, and 84.8% at the nucleotide level. The relatedness is less extensive than that found for mammals, e.g. human and mouse, and is evidence that the two hydra species diverged early in evolution. From each hydra species only one B-type cyclin was found, showing equal relatedness to the B1 and B2 subtypes of cyclins, hinting at a role as common ancestor before the split into B1 and B2 cyclins occurred. All three hydra cyclins contain regulation signals typical for G2/M cyclins, such as a ubiquitin destruction box at the amino terminus, needed for rapid degradation of the protein, and translation and polyadenylation elements in the 3' untranslated region to regulate RNA storage and RNA degradation. In hydra cell-cycle times vary depending on feeding regime and growth conditions. Cyclin B RNA expression was found to precede the daily mitotic rhythm induced by feeding. During head regeneration cyclin B expression showed the expected drop early during regeneration and an increase later. At the cellular level strongest expression of cyclin B RNA and protein was detected in interstitial cells which possess with one day the shortest cell-cycle time in hydra. Epithelial cells with a three-day cell-cycle rhythm showed variable, and differentiated cells no cyclin B expression. Regions of hydra containing high numbers of proliferating cells, such as developing buds exhibited elevated levels of cyclin B expression.
Multipactor prediction with multi-carrier signals: Experimental results and discussions on the 20-gap-crossing rule

This work analyzes the 20-gap crossing rule from a theoretical point of view. It has been found that, depending on some signal parameters, the 20-gap-crossing rule yields predictions laying between two limit cases: It may be either excessively conservative or closer to breakdown value with little (or nonexistent) margin. Such limit cases have been experimentally assessed with two test campaigns in C and Ku-bands.
Targeting Metabolism as a Novel Therapeutic Approach to Autoimmunity, Inflammation, and Transplantation

Immune cell activation and differentiation occurs concurrently with metabolic reprogramming. This ensures that activated cells generate the energy and substrates necessary to perform their specified function. Likewise, the metabolic programs among different cells of the immune system vary. By targeting different metabolic pathways, these differences allow for selective regulation of immune responses. Further, the relative susceptibility of cells to a metabolic inhibitor is dictated by their metabolic demands; cellular selectivity is based on demand. Therefore, where differences exist in metabolic pathways between healthy and pathogenic cells, there is opportunity for selective regulation with agents lacking intrinsic specificity. There are now a host of studies demonstrating how inhibitors of metabolism (e.g., glycolysis, glutamine metabolism, and fatty acid oxidation) can regulate immune responses and treat immune-mediated pathogenesis. In this brief review we detail how inhibitors of metabolism can be employed to regulate immune responses in both autoimmunity and transplantation.
Anabolic Steroid Use in Weightlifters and Bodybuilders: An Internet Survey of Drug Utilization

Purpose:Dietary supplements and ergogenic agents, including anabolic steroids, are common components of present-day bodybuilder and weightlifter training regimens. Prior reports of anabolic steroid use suggest polypharmacy and high doses of injectable agents. Hypothesis:To provide an updated description of anabolic steroid regimens employed by weightlifters and bodybuilders and to determine the extent to which anabolic steroid-associated behaviors are consistent with substance dependence. Study Design:Web-based survey. Methods:Links to the Web-based survey instrument were established from leading bodybuilding and fitness web pages. The questionnaire included demographic information, anabolic drug use history, adverse effects, information sources, and steroid use behavior consistent with criteria for a substance dependence disorder. Results:A total of 207 subjects provided a detailed anabolic steroid drug history. Steroid regimens included a mean of 3.1 agents, involved cycles ranging from 5 to 10 weeks, and often included doses 5 to 29 times greater than physiologic replacement doses. Behavior consistent with a substance dependence disorder was endorsed by 33% of respondents. Conclusions:These findings suggest that anabolic steroid use among weightlifters and bodybuilders continues, generally involving multiple steroids and additional dietary supplementary agents. The adverse effects, polypharmacy, large dosages, and risk of substance abuse are all major health care concerns that require further study. Clinical Relevance:The survey findings provide sports medicine practitioners a reasonable estimate of the expected drug history among bodybuilders and weightlifters for the use of performance-enhancing agents.
Transfer of Mother Tongue Rhetoric among Undergraduate Students in Second Language Writing

Mother tongue rhetoric transfer is unavoidable in ESL writings, especially for Iranian ESL learners, since Persian and English language is quite different. The paper discusses the negative transfer of mother tongue rhetoric in Iranian undergraduate ESL learners’ writings from the perspectives of choosing rhetorical structure in English and Persian writing. In this regard, 50 intermediate undergraduate Iranian students who are a bachelor in engineering fields at two private higher education institutions located in Malaysia, are selected as participants to give their opinion about which style they prefer to use for both English and Persian writing. Statistical analysis of the participants' performance indicates that Iranian undergraduate students use the same rhetorical pattern for their both Persian and English writing and there is no consideration regarding the knowledge of L1 and L2 differences. The results also state that above 70% of the participants prefer to give a general comment about the topic and encourage readers at the end of the writing in their English and Persian essays.
Reassessing the relationship between the financial sector and economic growth: Dynamic panel evidence

Historically, the development of the financial sector has been an indispensable driver of economic growth. In the aftermath of the Great Recession, there is a pressing need to reassess the role of the financial sector in the determination of economic growth. Using a dynamic panel framework, our analysis covers 34 European and Commonwealth of Independent States economies for the period 1998â€“2014 and controls for the role of macroeconomic and institutional variables. Our evidence suggests that the potential benefits of the financial sector finance may have dramatically reversed in recent years, resulting in â€œunâ€ creative destruction. â€ The results suggest, tentatively, that there has been a severance of the link between the financial sector and the real economy. The results, however, vary according to the level of economic development across the European and Commonwealth of Independent States economies. In the case of developing market economies, the financial intermediation proxies are not significant in explaining economic growth. The effect of changes in investment expenditure, the money supply, wages, unit labour costs, and trade openness is found to be strong and in line with a priori expectations across all country samples. Notably, government consumption is also found to be a significant driver of economic growth, except in the developing market economies in the period following the Great Recession. In line with the growing consensus in other research areas, we provide evidence of a robust role for the institutional framework proxied by the quality of governance in determining economic development.
Regulation of directional cell migration by membrane-induced actin bundling

Summary During embryonic development and in metastatic cancers, cells detach from the epithelium and migrate with persistent directionality. Directional cell migration is also crucial for the regeneration and maintenance of the epithelium and impaired directional migration is linked to chronic inflammatory diseases. Despite its significance, the mechanisms controlling epithelial cell migration remain poorly understood. Villin is an epithelial-cell-specific actin modifying protein that regulates epithelial cell plasticity and motility. In motile cells villin is associated with the highly branched and the unbranched actin filaments of lamellipodia and filopodia, respectively. In this study we demonstrate for the first time that villin regulates directionally persistent epithelial cell migration. Functional characterization of wild-type and mutant villin proteins revealed that the ability of villin to self-associate and bundle actin as well as its direct interaction with phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2] regulates villin-induced filopodial assembly and directional cell migration. Our findings suggest that convergence of different signaling cascades could spatially restrict villin activity to areas of high PtdIns(4,5)P2 and F-actin concentration to assemble filopodia. Furthermore, our data reveal the ability of villin to undergo actin- and PtdIns(4,5)P2-induced self-association, which may be particularly suited to coalesce and reorganize actin bundles within the filopodia.
Smoking rates among gamblers at Nevada casinos mirror US smoking rate

Objectives: To determine the percentage of gamblers who smoke while gambling at three of Nevada’s major gambling destinations, Las Vegas, Reno/Sparks and Lake Tahoe. Methods: Teams of two people counted the number of smokers and total number of gamblers at various Nevada casinos. The total number of gamblers observed smoking was then multiplied by three to determine the total number of smokers. This methodology for determining the number of smokers in a room was established by Repace and Lowry in 1980. Results: We observed a total of 14 052 gamblers at the three sites, of which a total of 947 were smoking. We estimated the percentage of smokers at three gaming tourist centres in Nevada (Las Vegas, Reno/Sparks and Lake Tahoe). The percentage of smokers at Las Vegas (20.3% (95% CI 0.9)) and Reno/Sparks (21.5% (95% CI 1.2%)) did not significantly differ from the US population percentage of smokers (20.9% (95% CI 0.6%)) (p>0.05). However, at Lake Tahoe the percentage of smokers (16.4% (95% CI 1.8%)) was significantly lower than the published US population smoker percentage (p<0.0001). Mean percentage of smokers by location did not significantly differ (p = 0.43) Conclusions: The results of this study suggest that the percentage of gamblers who smoke was less than or not different from the overall US percentage of a population who smoke. These findings provide additional evidence to refute the exemption to smoking bans for casinos based upon the supposition that a greater percentage of casino customers are smokers than the general population and therefore a smoking ban for casinos may result in an economic hardship.
On the Rationality of Investors – Lunar Phases and Equity Returns in Poland

Purpose – The paper examines the popular belief that the cycles of the moon affect human moods, which is then reflected in investor behaviour. Hence, the relation between lunar phases and equity returns in Poland was examined. Design/methodology/approach – New (full) moons were called nine-day windows with the centre in the new (full) moon day. Arithmetic daily index returns and average daily and cumulative returns were calculated for the session days in the new and full moon windows. Then the lunar effect on the market portfolio was observed with additional analysis for size effect, calendar month effect, and half-of-the-month effect. A robustness check tested the results. Findings – Average returns around full moon dates were substantially lower than returns around new moon dates. For size-related indexes, the results were similar. However, for small companies the differences were somewhat smaller. Average returns both for bear and bull months were positive and quite similar during the new moon phase. Average returns for full moon phases were tangibly negative for bear months and much lower for bull month as compared with results for the new moon phase. Both the lunar and the half of the month effects seemed to be important for returns in Poland. Originality/value – The study concentrated on the lunar effect for returns on the Warsaw Stock Exchange. The applied methodology is new for studying the relation for Poland.
Syndecan-1 Modulates the Motility and Resolution Responses of Macrophages

Objective—Syndecan-1 (Sdc-1) is a member of a family of cell surface proteoglycans, which has been reported to participate in the regulation of events relevant to tissue repair and chronic injury responses, including cell–substrate interactions, matrix remodeling, and cell migration. In this study, we report the functional significance of Sdc-1 in polarized macrophage populations and its role in adhesion and motility events relevant to resolution of the inflammatory program. Approach and Results—Macrophage Sdc-1 expression is associated with differentiated M2 macrophages with high intrinsic motility, and Sdc-1 deficiency is characterized by impaired migration and enhanced adhesion. Leukocyte infiltration and emigration were examined in a thioglycollate-induced model of peritonitis in Sdc-1+/+ and Sdc-1−/− mice. Although the infiltration of inflammatory cells was similar in both cohorts, a significant delay in the lymphatic clearance of Sdc-1−/− macrophages was observed. Moreover, we observed enhanced inflammation and greater burden of atherosclerotic plaques in ApoE−/−Sdc-1−/− mice maintained on a Western diet. Conclusions—These results demonstrate that defective motility in Sdc-1−/− macrophages promotes a persistent inflammatory state with relevance to the pathogenesis of atherosclerosis.
Simulations of apo and holo-fatty acid binding protein: structure and dynamics of protein, ligand and internal water.

Two molecular dynamics simulations of 5 ns each have been carried out for rat intestinal fatty acid binding protein, in apo-form and with bound palmitate. The fatty acid and a number of water molecules are encapsulated in a large interior cavity of the barrel-shaped protein. The simulations are compared to experimental data and analyzed in terms of root mean square deviations, atomic B-factors, secondary structure elements, hydrogen bond patterns, and distance constraints derived from nuclear Overhauser experiments. Excellent agreement is found between simulated and experimental solution structures of holo-FABP, but a number of differences are observed for the apo-form. The ligand in holo-FABP shows considerable displacement after about 1.5 ns and displays significant configurational entropy. A novel computational approach has been employed to identify internal water and to capture exchange pathways. Orifices in the portal and gap regions of the protein, discussed in the experimental literature, have been confirmed as major openings for solvent exchange between the internal cavity and bulk water. A third opening on the opposite side of the barrel experiences significant exchange but it does not provide a pathway for further passage to the central cavity. Internal water is characterized in terms of density distributions, interaction energies, mobility, protein contact times, and water molecule coordination. A number of differences are observed between the apo and holo-forms and related to differences in the protein structure. Solvent inside apo-FABP, for example, shows characteristics of a water droplet, while solvent in holo-FABP benefits from interactions with the ligand headgroup and slightly stronger interactions with protein residues.
