description: The objective of this study was to describe the genetic population structure and demographic history of the goldb lotch grouper of Central Mediterranean Sea (Gulf of Gabes and the coast of Li ya) using cytochrome b (cytb ) gene and seven nuclear microsatellites. Based on 940 base pairs of the cytochrome b segment, we found high levels of genetic variability for the two samples analysed (h = 0.833 ± 0.054 and h = 0.769 ± 0.120 respectively in Tunisia and Libya). Pairwise FST statistics among the two localities were negative (FST = -0.015; cytb gene) or low (FST = 0.011; microsatellite loci), suggesting a widespread gene flow. The high dispersal capabilities of larvae of E. costae coupled with the limited physical barriers in marine environment may be responsible for the high gene flow among E. costae populations along the two sites (Gulf of Gabès and Tadjourah). In summary, this study provides a preliminary assessment of geographical patterns of differentiation of E. costae in this region for conservation, management and stock identification.

description: We use the integrated polarized radio emission at 1.4 GHz ($Π_{\rm 1.4\,GHz}$) from a large sample of AGN (796 sources at redshifts $z<0.7$) to study the large-scale magnetic field properties of radio galaxies in relation to the host galaxy accretion state. We find a fundamental difference in $Π_{\rm 1.4\,GHz}$ between radiative-mode AGN (i.e. high-excitation radio galaxies, HERGs, and radio-loud QSOs) and jet-mode AGN (i.e. low-excitation radio galaxies, LERGs). While LERGs can achieve a wide range of $Π_{\rm 1.4\,GHz}$ (up to $\sim$$30\%$), the HERGs and radio-loud QSOs are limited to $Π_{\rm 1.4\,GHz} \lesssim 15\%$. A difference in $Π_{\rm 1.4\,GHz}$ is also seen when the sample is divided at 0.5% of the total Eddington-scaled accretion rate, where the weakly accreting sources can attain higher values of $Π_{\rm 1.4\,GHz}$. We do not find any clear evidence that this is driven by intrinsic magnetic field differences of the different radio morphological classes. Instead, we attribute the differences in $Π_{\rm 1.4\,GHz}$ to the local environments of the radio sources, in terms of both the ambient gas density and the magnetoionic properties of this gas. Thus, not only are different large-scale gaseous environments potentially responsible for the different accretion states of HERGs and LERGs, we argue that the large-scale magnetised environments may also be important for the formation of powerful AGN jets. Upcoming high angular resolution and broadband radio polarization surveys will provide the high precision Faraday rotation measure and depolarization data required to robustly test this claim.

description: A2 milk is an easily digestible product since it has only A2 beta-casein. In cattle, the A1 and A2 alleles are found in the population and the A2 milk is produced from A2A2 animals. Little is known about these alleles in other domestic dairy species. The present study aims to analyze sequence of genetic material available on public databases and quantify the animals genotyped. Eight domestic species were analyzed. There is strong evidence that domestic non-bovine species only carry A2 beta-casein. The data reported here for goats already confirm it due to the large number of animals genotyped as well as buffaloes. It means that they naturally produce A2 milk and no selection must be done. Thus, the fact that A2 milk is easier to digest can be used to add value to dairy product of these species. It helps to conquer new markets. It also improves people’s health and breeder profitability.

description: This study assesses the reproductive strategy of the common sardine Sardina pilchardus along the Algerian coast. Between January and December 2010, sampling was conducted at various inshore fishing landing site s in the Gulf of Bejaia. A total of 2919 individuals were collected, including 1317 males, 1053 females and 549 immature fish ranging in total length from 7.4 to 18 cm. The sex ratio was skewed towards females (M:F = 1.25) and differed among months and size classes. The size at the beginning of the maturity was 12.25 cm TL for females and 11.88 cm TL for males. The monthly variation in the gonads maturity stages showed that mature individuals we re present from November to April, where as they were absent from June to October. Both the gonadosomatic index (GSI) and microscopic examination of the gonads suggested that the spawning period occurs from November to April. Initiation of gonad maturation occurre d whe n se a te mpe rature drops (Nove mbe r). In the Gulf of Be jaia, characte rize d with rathe r oligotrophic wate rs, sardine spawning occurred at sea water temperatures between 15 and 18°C and during periods of higher environmental productivity. These results have a practical significance to implement appropriate management measures for sustainable management and conservation of one of the most economically important fish species along the Algerian coast.

description: We develop the effective theory of large-scale structure for non-Gaussian initial conditions. The effective stress tensor in the dark matter equations of motion contains new operators, which originate from the squeezed limit of the primordial bispectrum. Parameterizing the squeezed limit by a scaling and an angular dependence, captures large classes of primordial non-Gaussianity. Within this parameterization, we classify the possible contributions to the effective theory. We show explicitly how all terms consistent with the symmetries arise from coarse graining the dark matter equations of motion and its initial conditions. We also demonstrate that the system is closed under renormalization and that the basis of correction terms is therefore complete. The relevant corrections to the matter power spectrum and bispectrum are computed numerically and their relative importance is discussed.

description: Age, growth and mortality of the Starry weever Trachinus radiatus were studied for the first time from 214 individuals collected in the Gulf of Tunis b etween Feb ruary 2014 and January 2016. The significant relationship b etween length-weight was ob served for males (a = 0.011, b = 2.992, R2 = 0.981, n = 77) and females (a = 0.010, b = 3.036, R` = 0.957, n = 109). Age was estimated b y the ob servation of otoliths transverse thin sections. Age of individuals ranged from 1 to 15 years. The precision was measured b y two age estimations from two experts and indicated a good agreement b etween them (PA = 85.6%, CV = 3.8% and IAPE = 4.1%). The growth parameters of the von Bertalanffy model were TL∞ = 38.41 cm, W∞ = 507.47 g, K = 0.3396 year-1, t0 = 0 year for males and TL∞ = 45.46 cm, W∞ = 914.04 g, K = 0.2136 year-1, t0 = 0 year for females. Age at first sexual maturity (tm) of T. radiatus was 3.5 years, while the age at optimum length (topt) was 6.6 years. The natural mortality (M), total mortality (Z), fishing mortality (F) and exploitation (E) rates were respectively M = 0.429 yr-1, Z = 0.453 yr-1, F = 0.024 yr-1 and E = 0.053.

description: In the analysis of multivariate event times, frailty models assuming time-independent regression coefficients are often considered, mainly due to their mathematical convenience. In practice, regression coefficients are often time dependent and the temporal effects are of clinical interest. Motivated by a phase III clinical trial in multiple sclerosis, we develop a semiparametric frailty modelling approach to estimate time-varying effects for overdispersed recurrent events data with treatment switching. The proposed model incorporates the treatment switching time in the time-varying coefficients. Theoretical properties of the proposed model are established and an efficient expectation-maximization algorithm is derived to obtain the maximum likelihood estimates. Simulation studies evaluate the numerical performance of the proposed model under various temporal treatment effect curves. The ideas in this paper can also be used for time-varying coefficient frailty models without treatment switching as well as for alternative models when the proportional hazard assumption is violated. A multiple sclerosis dataset is analysed to illustrate our methodology.

description: This study was conducted to determine the effects of seasonal variation on condition factor (CF) and weight - length relationships (WLRs) in Holothuria pardalis collected during January to December 2016. Total (n = 452) sample of H. pardalis were collected during pre monsoon, monsoon and post monsoon season from two rocky shores of Buleji and Sunehri coast of Karachi. The highest mean length 17.1 ± 0.70 cm and weight 20.3±0.63 g were recorded in post-monsoon season and minimum length 10.7±0.59 cm and weight 14.0±0.72 g were recorded in pre-monsoon season. The results showed that H. pardalis has negative allometric (b < 3) growth characteristics in all seasons (P < 0.05) as it appears to be the general case in other holothurian species. One-way ANOVA test showed that the CF values were statistically difference among three seasons. The mean CF values in Buleji area were estimated statistically higher than in Sunehri in pre-monsoon and monsoon (P < 0.05). But, it was estimated lower in Buleji area than Sunehri area in post-monsoon (P < 0.05).

description: Light-matter interactions that lead to nonthermal changes in size of the sample constitute a photostrictive effect in many compounds. The photostriction phenomenon was observed in four main groups of materials, ferroelectrics, polar, and non-polar semiconductors, as well as in organic-based materials that are reviewed here. The key mechanisms of photostriction and its dependence on several parameters and perturbations are assessed. The major literature of the photostriction is surveyed, and the review ends with a summary of the proposed technical applications.

description: We present imaging and spectroscopic observations with HST and VLT of the ring of SN 1987A from 1994 to 2014. After an almost exponential increase of the shocked emission from the hotspots up to day ~8,000 (~2009), both this and the unshocked emission are now fading. From the radial positions of the hotspots we see an acceleration of these up to 500-1000 km/s, consistent with the highest spectroscopic shock velocities from the radiative shocks. In the most recent observations (2013 and 2014), we find several new hotspots outside the inner ring, excited by either X-rays from the shocks or by direct shock interaction. All of these observations indicate that the interaction with the supernova ejecta is now gradually dissolving the hotspots. We predict, based on the observed decay, that the inner ring will be destroyed by ~2025.

description: Two conjugates (1 and 2) of camptothecin (CPT) and 4β-anilino-4′-O-demethylepipodophyllotoxin were previously shown to exert antitumor activity through inhibition of topoisomerase I (topo I). In this current study, two novel conjugates (1E and 2E) with an open E-ring in the CPT moiety were first synthesized and evaluated for biological activity in comparison with their intact E-ring congeners. This novel class of CPT derivatives exhibits its antitumor effect against CPT-sensitive and -resistant cells, in part, by inhibiting topo I-linked DNA (TLD) religation. An intact E-ring was not essential for the inhibition of TLD religation, although conjugates with an open E-ring were less potent than the closed ring analogs. This lower religation potency resulted in decreased formation of protein-linked DNA breaks (PLDBs), and hence, less cell growth inhibition. In addition to their impact on topo I, conjugates 1E, 2, and 2E exhibited a minor inhibitory effect on topo II-induced DNA cleavage. The novel structures of 1E and 2E may present scaffolds for further development of dual function topo I and II inhibitors with improved pharmacological profiles and physicochemical properties.

description: Different feeding habits may affect the blood parameters in fish species of the same family, even if they live in the same marine habitat. The aim of this study was to compare some haematological and biochemical parameters of two marine fish species of the same family, the saupe Sarpa salpa (Linnaeus, 1758) and the common two-banded seabream Diplodus vulgaris (Geoffroy Saint-Hilaire, 1817), and to establish the similarities and differences between these species. For this purpose red blood cells (RBC), haemoglobin concentration (Hb), haematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), glucose (GLU), triglycerides (TRIG), cholesterol (CHOL), serum total protein (TP), albumin (ALB), globulins (GLO), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were determined for 30 fish from each species. Statistical analysis showed significant differences in some haematological and biochemical (RBC, Hb, Hct, TP, ALB, GLO, AST, ALT, ALP and LDH) parameters between the two species. Lower values of RBC, Hb and Hct were found in S. salpa in comparison with D. vulgaris. These differences could be attributed to the feeding behavior, life style and habitat adaptation of the different fish species of the same family and contribute to knowledge of reference values of blood parameters in Sarpa salpa and Diplodus vulgaris. No significant differences were found in MCV, MCH, MCHC and GLU, TRIG, CHOL.

description: Merja Zerga is the most important wetland for wintering shorebirds in Morocco. To understand the role of intertidal habitats as feeding areas, a study that aims to analyse the composition, structure and spatial organization of macrobenthic fauna in the main habitats frequented by shorebirds has been conducted. From the analysis of 570 samples distributed over 19 stations, 46 species of benthic macrofauna, dominated by Molluscs and Polychaetes, were identified. Densities ranged from 305 to 25 663 individuals.m-2, with an average of 5 764 ind.m-2, and biomasses ranged from 3.92 to 52.65 g.m-2, with an average of 20.07 g.m-2. Four benthic assemblages were identified, distributed along a downstream- upstream gradient. Hydrological and sedimentary parameters, as well as the presence or absence of seagrass beds, were the main factors that structure the distribution and the functioning of benthic assemblages. Distribution maps of benthic assemblages, representing the main prey for shorebirds, are essential tools for managers to identify areas with high conservation issues for aquatic birds.

description: The classical max-flow min-cut theorem describes transport through certain idealized classical networks. We consider the quantum analog for tensor networks. By associating an integral capacity to each edge and a tensor to each vertex in a flow network, we can also interpret it as a tensor network, and more specifically, as a linear map from the input space to the output space. The quantum max flow is defined to be the maximal rank of this linear map over all choices of tensors. The quantum min cut is defined to be the minimum product of the capacities of edges over all cuts of the tensor network. We show that unlike the classical case, the quantum max-flow=min-cut conjecture is not true in general. Under certain conditions, e.g., when the capacity on each edge is some power of a fixed integer, the quantum max-flow is proved to equal the quantum min-cut. However, concrete examples are also provided where the equality does not hold. We also found connections of quantum max-flow/min-cut with entropy of entanglement and the quantum satisfiability problem. We speculate that the phenomena revealed may be of interest both in spin systems in condensed matter and in quantum gravity.

The current-voltage (I-V) relations were analyzed by an extension of the Poisson-Nernst-Planck (PNP) formulation of electrodiffusion, which includes local chemical interaction described by an offset in chemical potential, which likely reflects the difference in dehydration/solvation/rehydration energies in the entry/exit steps of permeation. The theory fits all of the data with few adjustable parameters: the diffusion coefficient of each ion species, the average effective charge distribution on the wall of the pore, and an offset in chemical potential for lithium and sodium ions. In particular, the theory explains the discrepancy between "selectivities" defined by conductance sequence and "selectivities" determined by the permeability ratios (i.e., reversal potentials) in biionic conditions. The extended PNP formulation seems to offer a successful combined treatment of selectivity and permeation. Conductance selectivity in this channel arises mostly from friction: different species of ions have different diffusion coefficients in the channel. Permeability selectivity of an ion is determined by its electrochemical potential gradient and local chemical interaction with the channel. Neither selectivity (in CRC) seems to involve different electrostatic interaction of different ions with the channel protein, even though the ions have widely varying diameters.

description: To allow studies of conformational changes within multi-molecular complexes, we present a simultaneous, 4-color single molecule fluorescence methodology implemented with total internal reflection illumination and camera based, wide-field detection. We further demonstrate labeling histidine-tagged proteins non-covalently with tris-Nitrilotriacetic acid (tris-NTA) conjugated dyes to achieve single molecule detection. We combine these methods to co-localize the mismatch repair protein MutSα on DNA while monitoring MutSα-induced DNA bending using Förster resonance energy transfer (FRET) and to monitor assembly of membrane-tethered SNARE protein complexes.

description: First we have assumed the most general static spherically symmetric black hole metric. The accretion of any general kind of fluid flow around the black hole have been investigated. The accretion of fluid flow around the modified Hayward black hole have been analyzed and we then calculated the critical point, fluid 4 velocity and velocity of sound during accretion process. Also the nature of the dynamical mass of black hole during accretion of fluid flow and taking into consideration of Hawking radiation from black hole i.e., evaporation of black hole have been analyzed.

description: The encapsulation of proteins in biomimetic silica has recently been shown to successfully maintain enzymes in their active state. Organophosphate (OP) compounds are employed as pesticides as well as potent chemical warfare nerve agents. Because these toxicants are life threatening, we sought to generate biomimetic silicas capable of responding to OPs. Here, we present the silica encapsulation of human drug metabolism enzyme carboxylesterase 1 (hCE1) in the presence of a range of catalysts. hCE1 was successfully encapsulated into silica particles when lysozyme or the peptide R5 were used as catalysts; in contrast, polyethyleneimine (PEI), a catalyst employed to encapuslate other enzymes, did not facilitate hCE1 entrapment. hCE1 silica particles in a column chromatography format respond to the presence of the organophosphate (OP) pesticides paraoxon and dimethyl-p-nitrophenyl phosphate in solution. These results may lead to novel approaches to detect OP pesticides or other weaponized agents that bind hCE1.

description: In May-June 2016 the Canadian Province of Alberta suffered one of the most devastating wildfires in its history. Here we show that in mid-April to early May 2016 the large-scale circulation in the mid- and high troposphere of the middle and sub-polar latitudes of the northern hemisphere featured a persistent high-amplitude planetary wave structure dominated by the non-dimensional zonal wave number 4. The strongest anticyclonic wing of this structure was located over western Canada. In combination with a very strong El Niño event in winter 2015/2016 this favored highly anomalous, tinder-dry and high-temperature conditions at the surface in that area, entailing an increased fire hazard there. This critically contributed to the ignition of the Alberta Wildfire in May 2016, appearing to be the costliest disaster in Canadian history thus far.

description: Background—The current rate of cesarean delivery in the United States is 31 percent. Previous studies have suggested that exercise during pregnancy may be associated with a lower risk of cesarean delivery, but sample sizes were small and methods often inadequate. This study examined whether or not an association exists between prenatal exercise and delivery mode using data from the 2004 and 2005 North Carolina Pregnancy Risk Assessment Monitoring System (PRAMS) survey. Methods—PRAMS postpartum questionnaire responses about frequency of exercise during the last 3 months of pregnancy for 1,955 women without a prior cesarean delivery were linked to birth certificates. Results—Among 1,342 women delivering at term, exercise was not associated with delivery mode in this data set: compared with women exercising less than once a week, neither women exercising 1 to 4 times per week nor those exercising 5 times or more per week had an altered risk of cesarean [RR (95% CL) 0.89 (0.69, 1.15), 1.04 (0.66, 1.64), respectively, adjusted for parity, gestational age, hypertension]. Among 613 women delivering preterm, the results were also not statistically significant, but a compelling trend toward a protective effect could be seen [RR (95% CL) 0.65 (0.38, 1.13), 0.62 (0.29, 1.33)]. Conclusions—Maternal self-reported frequency of exercise during pregnancy was not associated with a reduced risk of cesarean delivery. Larger studies with better exposure ascertainment may provide a more definitive answer.
Long-term D1-dopamine receptor sensitization in neonatal 6-OHDA-lesioned rats is blocked by an NMDA antagonist

description: Repeated administration of the D1-dopamine agonist SKF-38393 to adult rats having had dopaminergic neurons destroyed early in development results in an increasing enhancement of the behavioral response to SKF-38393 with each dose until a maximum is reached. This increased sensitivity lasts for at least 6 months. In the present study, this long-lasting change in behavioral responsiveness to repeated treatment with SKF-38393, referred to as D1-dopamine receptor priming, was shown to be dose dependent with smaller doses requiring an increased number of administrations to produce a maximal response when compared to higher doses. In addition, priming occurred equally well when treatment intervals ranged from 1 day to 14 days. These latter data reinforced the view that activation of D1-dopamine receptors results in a prolonged change in neural function. In subsequent experiments, D1-dopamine receptor priming was blocked by pretreatment with the NMDA-receptor antagonist MK-801. This antagonism of priming could not be attributed to a blockade of D1-dopamine receptors by MK-801 or to the induction of interfering behaviors. Because an NMDA antagonist interfered with D1-receptor priming as it does with other long-term neural messages, a common requirement for these diverse forms of neuronal plasticity appears to involve activation of the NMDA receptor. This functional link between NMDA receptors and dopaminergic function and its relationship to neuronal plasticity could have relevance to the biochemical mechanisms involved in learning and to symptoms in central disorders during development that worsen over time, particularly those proposed to involve malfunctioning dopaminergic mechanisms.
Diet of Silver scabbardfish Lepidopus caudatus (Euphrasen, 1788) in the Northern Aegean Sea

description: This study is based on the results of an extensive research carried out on silver scabbardfish Lepidopus caudatus from 2003 to 2005 in the Northern Aegean Sea (NAS). Data were collected from both commercial fisheries and research bottom trawl surveys. 264 specimens of silver scabbardfish, caught between 200 and 600 m depth, were processed for diet analysis. The silver scabbardfish diet covers different trophic levels, including euphausiids, decapods, fish and cephalopods. Overall, euphausiids were found to be the most important prey. Ontogenetically, the L.caudatus diet gradually changed from crustaceans, consumed by the smaller individuals to fish and cephalopods. During the sampling period, radical changes in the diet composition were observed: from euphausiids to fish between 2003 and 2004 and from fish to decapoda, euphausiids and cephalopods between 2004 and 2005. During 2004, feeding on high trophic level preys was attributed to lack of euphausiids. It was suggested that euphausiids play a crucial role in the energy transfer between lower and higher trophic levels in the deep demersal areas of the NAS.
Health information-seeking behavior and older African American women.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: This study explored the ways in which urban, older, African American women obtain health information and some of the factors that influence such activity. Among the possible determinants examined were self-perceived literacy, access to health information, and mobility. The findings suggest that respondents receive health information from their physicians, the mass media, and members of their social networks. The results of this research also indicated that members of this population have a highly positive perception of the public library, although only a small segment use the library regularly, and that it may be in the interest of the library to investigate the role it could play in providing health information to older adults.

description: The dynamical relationship between magnetic storms and magnetospheric substorms is one of the most controversial issues of contemporary space research. Here, we address this issue through a causal inference approach to two corresponding indices in conjunction with several relevant solar wind variables. We find that the vertical component of the interplanetary magnetic field is the strongest and common driver of both storms and substorms. Further, our results suggest, at least based on the analyzed indices, that there is no statistical evidence for a direct or indirect dependency between substorms and storms and their statistical association can be explained by the common solar drivers. Given the powerful statistical tests we performed (by simultaneously taking into account time series of indices and solar wind variables), a physical mechanism through which substorms directly or indirectly drive storms or vice versa is, therefore, unlikely.

description: This study aims to assess the effect of marine pollution on some biological parameters of the gastropod Patella caerulea collected from one unpolluted zone and three polluted areas of the Tunisian coastline. Three biological approaches have been carried out: biochemical, morphometric and reproductive. Measurement of acetylcholinesterase activity (AChE) in the digestive glands of the limpet showed a significant decrease in the polluted sites compared to that of the control medium. The multidimensional analysis of the morphometric ratios and the contour analysis of the shell show that the morphometry of Mediterranean limpet is influenced by pollution. The comparison of the reproduction cycle of the limpets from control and contaminated sites highlights two major differences: the first concerns the maximum reached by GSI, which is much higher in the polluted site and the second corresponds to a lag of one month in the spawning period of limpets from polluted zones. Regarding the fecundity study, the limpet tends to maximize the number of oocytes at the expense of size and quality in polluted environments. These changes in the biological traits of the limpet in response to the pollution are considered as sensitive biomarkers of littoral contamination and can be used in future biomonitoring programs.
