    Hansen, Henning Otte

    2016-01-01

    International trade and specialization with agricultural raw materials and processed products is often rather limited due to trade barriers, logistic problems and food security. This production of raw fur skin - which is also considered an agricultural product - mostly takes place in the Western...... hemisphere, and to a high degree in Europe, while processing and production of fur garments now more and more takes place in Asia. The objective of this paper is to analyze, quantify and explain trade patterns and international specialization within fur skin and fur garments focusing on Europa and Asia...... trade with fur skin products between Asia and Europe has increased remarkably during the recent decades. Europe accounts for a major share of world production and export of raw fur skin, and Asia accounts for the major part of the subsequent processing. This means that there is a significant export...

    This paper explores the notion of deeper luxury, which insists that 'real' luxury should involve sustainable practices in the production and consumption of luxury goods. It traces historical and recent developments in the field of fur, to understand the implications, uncertainties and ambiguities...... of luxury’s confrontation with sustainability. Considering fur in relation to future standards for luxury products, we raise questions about moral problematisation and justification of luxury in terms of sustainability. We first examine the encounter of luxury with sustainability and explain...... the significance of the notion of ‘deeper luxury’. After taking stock of the impact of sustainability on luxury and various directions in which sustainable luxury is evolving, we discuss concepts of sustainable development in relation to the history of moral problematisation of luxury.

  10. ''FUR'' - one size suits all

    International Nuclear Information System (INIS)

    Rutland, M.; Que, L.; Hassan, I.M.

    2000-01-01

    This work used amalgamated data from previous projects in order to test the concept that when organ function is expressed in terms of tracer kinetics, the results are independent of patient size or gender. Dynamic gamma camera studies were analysed by measuring the rate of movement of tracers from the blood into various organs. These rates were expressed as a ''fractional uptake rate'' (FUR), which is the fraction of tracer in the blood taken up by the organ per unit time. As these values were small, it was convenient to express the FUR per million seconds. The FUR was calculated using the expression FUR = SLOPE (of Rutland-Patlak plot), multiplied by B(0) (the blood curve value back-extrapolated to time zero), and divided by the TOTAL amount of tracer injected. Data were used from adult patients between the ages of 20 and 49 years who had normal organ function. Organ/tracer groups studied were the skeletal uptake of 99m Tc-MDP, the renal uptake of 99m Tc-MAG3, the renal uptake of 99m Tc-MDP, the renal uptake of 99m Tc-DTPA, the hepatic uptake of 99m Tc-colloid, the splenic uptake of 99m Tc-colloid, and the hepatic uptake of 99m Tc-DISIDA. Each organ/tracer group was divided into three subgroups according to patient size (smallest, middle and largest), and also into subgroups according to gender. Comparison of these subgroups did not show any significant size- or gender-related differences in FUR values. It is concluded that for patients with normally functioning organs the FUR is independent of patient size or gender. Thus, the FUR is a valuable way of expressing organ function, particularly in patients with unusual or rapidly changing body size, such as children. (orig.)

    Full Text Available BACKGROUND: Retinoic acid-inducible gene I (RIG-I-like receptors (RLRs had been demonstrated to prime interferon (IFN response against viral infection via the conserved RLR signaling in fish, and a novel fish-specific gene, the grass carp reovirus (GCRV-induced gene 2 (Gig2, had been suggested to play important role in host antiviral response. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we cloned and characterized zebrafish Gig2 homolog (named Danio rerio Gig2-I, DreI, and revealed its antiviral role and expressional regulation signaling pathway. RT-PCR, Western blot and promoter activity assay indicate that DreI can be induced by poly I:C, spring viremia of carp virus (SVCV and recombinant IFN (rIFN, showing that DreI is a typical ISG. Using the pivotal signaling molecules of RLR pathway, including RIG-I, MDA5 and IRF3 from crucian carp, it is found that DreI expression is regulated by RLR cascade and IRF3 plays an important role in this regulation. Furthermore, promoter mutation assay confirms that the IFN-stimulated regulatory elements (ISRE in the 5' flanking region of DreI is essential for its induction. Finally, overexpression of DreI leads to establish a strong antiviral state against SVCV and Rana grylio virus (RGV infection in EPC (Epithelioma papulosum cyprinid cells. CONCLUSIONS/SIGNIFICANCE: These data indicate that DreI is an antiviral protein, which is regulated by RLR signaling pathway.

  13. Hybrid fur rendering: combining volumetric fur with explicit hair strands

    DEFF Research Database (Denmark)

    Andersen, Tobias Grønbeck; Falster, Viggo; Frisvad, Jeppe Revall

    2016-01-01

    Hair is typically modeled and rendered using either explicitly defined hair strand geometry or a volume texture of hair densities. Taken each on their own, these two hair representations have difficulties in the case of animal fur as it consists of very dense and thin undercoat hairs in combination...... with coarse guard hairs. Explicit hair strand geometry is not well-suited for the undercoat hairs, while volume textures are not well-suited for the guard hairs. To efficiently model and render both guard hairs and undercoat hairs, we present a hybrid technique that combines rasterization of explicitly...... defined guard hairs with ray marching of a prismatic shell volume with dynamic resolution. The latter is the key to practical combination of the two techniques, and it also enables a high degree of detail in the undercoat. We demonstrate that our hybrid technique creates a more detailed and soft fur...

  15. Pet fur or fake fur? A forensic approach

    Science.gov (United States)

    2014-01-01

    Background In forensic science there are many types of crime that involve animals. Therefore, the identification of the species has become an essential investigative tool. The exhibits obtained from such offences are very often a challenge for forensic experts. Indeed, most biological materials are traces, hair or tanned fur. With hair samples, a common forensic approach should proceed from morphological and structural microscopic examination to DNA analysis. However, the microscopy of hair requires a lot of experience and a suitable comparative database to be able to recognize with a high degree of accuracy that a sample comes from a particular species and then to determine whether it is a protected one. DNA analysis offers the best opportunity to answer the question, ‘What species is this?’ In our work, we analyzed different samples of fur coming from China used to make hats and collars. Initially, the samples were examined under a microscope, then the mitochondrial DNA was tested for species identification. For this purpose, the genetic markers used were the 12S and 16S ribosomal RNA, while the hypervariable segment I of the control region was analyzed afterwards, to determine whether samples belonged to the same individual. Results Microscopic examination showed that the fibres were of animal origin, although it was difficult to determine with a high degree of confidence which species they belonged to and if they came from a protected species. Therefore, DNA analysis was essential to try to clarify the species of these fur samples. Conclusions Macroscopic and microscopic analysis confirmed the hypothesis regarding the analyzed hair belonging to real animals, although it failed to prove with any kind of certainty which actual family it came from, therefore, the species remains unknown. Sequence data analysis and comparisons with the samples available in GenBank showed that the hair, in most cases, belonged to the Canidae family, and in one case only to

    1980-01-01

    The Gossamer Albatross II is seen here being assembled in a hangar at the Dryden Flight Research Center, Edwards, California. The original Gossamer Albatross is best known for completing the first completely human powered flight across the English Channel on June 12, 1979. The Albatross II was the backup craft for the Channel flight. The aircraft was fitted with a small battery-powered electric motor and flight instruments for the NASA research program in low-speed flight. NASA completed its flight testing of the Gossamer Albatross II and began analysis of the results in April, 1980. During the six week program, 17 actual data gathering flights and 10 other flights were flown here as part of the joint NASA Langley/Dryden flight research program. The lightweight craft, carrying a miniaturized instrumentation system, was flown in three configurations; using human power, with a small electric motor, and towed with the propeller removed. Results from the program contributed to data on the unusual aerodynamic, performance, stability, and control characteristics of large, lightweight aircraft that fly at slow speeds for application to future high altitude aircraft. The Albatross' design and research data contributed to numerous later high altitude projects, including the Pathfinder.

    Grumman OV-1C in the hangar used at the time by the Army at Edwards Air Force Base. This OV-1C Mohawk, serial #67-15932, was used in a joint NASA/US Army Aviation Engineering Flight Activity (USAAEFA) program to study a stall-speed warning system in the early 1980s. NASA designed and built an automated stall-speed warning system which presented both airspeed and stall speed to the pilot. Visual indication of impending stall would be displayed to the pilot as a cursor or pointer located on a conventional airspeed indicator. In addition, an aural warning at predetermined stall margins was presented to the pilot through a voice synthesizer. The Mohawk was developed by Grumman Aircraft as a photo observation and electronic reconnaissance aircraft for the US Marines and the US Army. The OV-1 entered production in October 1959 and served the US Army in Europe, Korea, the Viet Nam War, Central and South America, Alaska, and during Desert Shield/Desert Storm in the Middle East. The Mohawk was retired from service in September 1996. 133 OV-1Cs were built, the 'C' designating the model which used an IR (infrared) imaging system to provide reconnaissance.

    1987-01-01

    A historic cohort mortality study was carried out among two groups of male workers in the Montreal fur industry: 263 dressers and dyers and 599 fur garment manufacturers. The first group is exposed to a very wide variety of chemicals used in tanning, cleaning, and dyeing fur, including substances considered to be carcinogenic and/or mutagenic. The second group is exposed to residue from the dressing and dyeing stage and to respirable fur dust. The cohorts consisted of all active members of two unions as of January 1, 1966. The mean age of the workers was 43.2 and the mean number of years since first employment 14.1. The follow-up period was from January 1, 1966, to December 31, 1981; 95% of the workers were successfully traced. Observed deaths were compared with those expected based on mortality rates of the population of metropolitan Montreal. Standardized mortality ratios (SMRs) for the manufacturers were significantly low, probably because of the ethnic composition of the cohort and a healthy worker effect. SMRs for the dressers and dyers were also low, but not as low as for the manufacturers. When attention was restricted to the French Canadians in the cohort, the observed deaths were close to the expected; there was a noteworthy excess of colorectal cancer (four observed, 0.8 expected) for dressers and dyers. Apart from this weak suggestive evidence, the results did not indicate any excess mortality risks in the fur industry. However, because of the relatively small number of expected and observed deaths in the cohort and especially among the heavily exposed dressers and dyers, the confidence intervals around SMR estimates were wide and excess risks cannot be ruled out.

  8. DAST Being Calibrated for Flight in Hangar

    Science.gov (United States)

    1982-01-01

    DAST-2, a modified BQM-34 Firebee II drone, undergoes calibration in a hangar at the NASA Dryden Flight Research Center. After the crash of the first DAST vehicle, project personnel fitted a second Firebee II (serial # 72-1558) with the rebuilt ARW-1 (ARW-1R) wing. The DAST-2 made a captive flight aboard the B-52 on October 29, 1982, followed by a free flight on November 3, 1982. During January and February of 1983, three launch attempts from the B-52 had to be aborted due to various problems. Following this, the project changed the launch aircraft to a DC-130A. Two captive flights occurred in May 1983. The first launch attempt from the DC-130 took place on June 1, 1983. The mothership released the DAST-2, but the recovery system immediately fired without being commanded. The parachute then disconnected from the vehicle, and the DAST-2 crashed into a farm field near Harper Dry Lake. Wags called this the 'Alfalfa Field Impact Test.' These are the image contact sheets for each image resolution of the NASA Dryden Drones for Aerodynamic and Structural Testing (DAST) Photo Gallery. From 1977 to 1983, the Dryden Flight Research Center, Edwards, California, (under two different names) conducted the DAST Program as a high-risk flight experiment using a ground-controlled, pilotless aircraft. Described by NASA engineers as a 'wind tunnel in the sky,' the DAST was a specially modified Teledyne-Ryan BQM-34E/F Firebee II supersonic target drone that was flown to validate theoretical predictions under actual flight conditions in a joint project with the Langley Research Center, Hampton, Virginia. The DAST Program merged advances in electronic remote control systems with advances in airplane design. Drones (remotely controlled, missile-like vehicles initially developed to serve as gunnery targets) had been deployed successfully during the Vietnamese conflict as reconnaissance aircraft. After the war, the energy crisis of the 1970s led NASA to seek new ways to cut fuel use and

    Full Text Available Drei Theoriekatastrophen sind dafür verantwortlich, dass nach anfänglich hoher Theorieaffinität die deutsche Rechtsdogmatik sich heute gegenüber Sozialtheorien weitgehend immunisiert hat. Der Beitrag diskutiert die Alternative eines distanzierten Umgangs mit Sozialtheorien. Dieser kann in der Begegnung von Sozialtheorie und Recht einen rechtsdogmatischen Mehrwert dann erzeugen, wenn es der Rechtsdogmatik gelingt, dem prekären Verhältnis von Autonomie und Interdependenz in drei unterschiedlichen Dimensionen gerecht zu werden: (1 Theoriekonkurrenz: Wie soll das Recht eine Auswahl treffen, wenn konkurrierende Sozialtheorien miteinander nicht kompatible Analysen von Sozialphänomenen liefern? (2 Wissenstransfer: Wie lassen sich Konstrukte der Sozialtheorien in das Recht übertragen? (3 Und schliesslich die heikelste Frage nach der Normativität von Sozialtheorien: Lassen sich aus wissenschaftlichen Theorien normative Kriterien für die Rechtspraxis gewinnen? Antworten zu diesen Fragen werden am Beispiel der horizontalen Grundrechtswirkung in halb-privaten Netzwerken der Medizinforschung formuliert. Three theory disasters are responsible for the fact that, after an initial close affinity to theory, German legal doctrine has now become largely immunised against social theories. This paper discusses the alternative of a distanced approach to social theories. At the point where social theory comes into contact with law, this approach is able to generate added value for legal doctrine, if legal doctrine is able to take into account the precarious relationship between autonomy and interdependence in three different dimensions: (1 competition between theories: how is the law to make a selection, when competing social theories provide mutually incompatible analyses of social phenomena? (2 knowledge transfer: how can constructs of social theories be transferred to the law? (3 and, finally, the highly complex issue of the normativity of social theories

    Full Text Available The heat transfer through Svalbard reindeer (Rangifer tarandus platyrhynchus fur samples was studied with respect to wind velocity, season and animal age. A total of 33 dorsal fur sections were investigated using a wind tunnel. Insulation varied with season (calving, summer, autumn and winter. At zero wind velocity, fur insulation was significantly different between seasons for both calf and adult fur samples. At the same time, there was no significant difference between calf and adult insulation for the summer, autumn and winter seasons. Calf fur insulated as well as adult fur. Winter insulation of Svalbard reindeer was approximately 3 times that of summer. Increasing wind veloci¬ty increased heat loss, however, the increase was not dramatic. When wind coefficients (slope of the heat transfer regression lines were compared, between season and between calf and adult, no significant differences were reported. All fur samples showed similar increases in heat transfer for wind velocities between 0 and 10 m.s-1. The conductance of winter fur of Svalbard reindeer was almost half that of caribou fur. Also, conductance was not as greatly influenced by wind as caribou fur

  13. Transcriptional regulation by Ferric Uptake Regulator (Fur) in pathogenic bacteria.

    Science.gov (United States)

    Troxell, Bryan; Hassan, Hosni M

    2013-01-01

    In the ancient anaerobic environment, ferrous iron (Fe(2+)) was one of the first metal cofactors. Oxygenation of the ancient world challenged bacteria to acquire the insoluble ferric iron (Fe(3+)) and later to defend against reactive oxygen species (ROS) generated by the Fenton chemistry. To acquire Fe(3+), bacteria produce low-molecular weight compounds, known as siderophores, which have extremely high affinity for Fe(3+). However, during infection the host restricts iron from pathogens by producing iron- and siderophore-chelating proteins, by exporting iron from intracellular pathogen-containing compartments, and by limiting absorption of dietary iron. Ferric Uptake Regulator (Fur) is a transcription factor which utilizes Fe(2+) as a corepressor and represses siderophore synthesis in pathogens. Fur, directly or indirectly, controls expression of enzymes that protect against ROS damage. Thus, the challenges of iron homeostasis and defense against ROS are addressed via Fur. Although the role of Fur as a repressor is well-documented, emerging evidence demonstrates that Fur can function as an activator. Fur activation can occur through three distinct mechanisms (1) indirectly via small RNAs, (2) binding at cis regulatory elements that enhance recruitment of the RNA polymerase holoenzyme (RNAP), and (3) functioning as an antirepressor by removing or blocking DNA binding of a repressor of transcription. In addition, Fur homologs control defense against peroxide stress (PerR) and control uptake of other metals such as zinc (Zur) and manganese (Mur) in pathogenic bacteria. Fur family members are important for virulence within bacterial pathogens since mutants of fur, perR, or zur exhibit reduced virulence within numerous animal and plant models of infection. This review focuses on the breadth of Fur regulation in pathogenic bacteria.

Die Autorin schlägt Korrekturen der filmographischen Daten vor, wie etwa die Einbindung des letzten „Jewish Elder“ des Ghettos, Benjamin Murmelstein, als Ko-Autor des Scripts. Eine Rekonstruktion des Datums, des Zeitpunkts und des Orts der ersten offiziellen Vorführung des Films für Delegierte des Komitees des Internationalen Roten Kreuzes wird durch eine komparative Untersuchung von verschiedenen Quellen und auf Textanalyse basierenden Ausschlussverfahren möglich. Bisherige Auffassungen des beabsichtigten Effekts und der Zielgruppe des Films revidierend, lenkt der Artikel die Aufmerksamkeit auf den Fakt, dass der Film vom Reichssicherheitshauptamt (RSHA 1942 initiiert und zum Kriegsende drei sorgfältig ausgewählten Gruppen vorgeführt wurde. Eine Untersuchung des Publikums der Premiere am 6. April 1945 lässt eine Neubewertung der Frage zu, ob der Film als Propagandafilm eingestuft werden kann oder eher als Strategem des deutschen Geheimdienstes.

  2. Fur is a repressor of biofilm formation in Yersinia pestis.

    Directory of Open Access Journals (Sweden)

    Fengjun Sun

    Full Text Available BACKGROUND: Yersinia pestis synthesizes the attached biofilms in the flea proventriculus, which is important for the transmission of this pathogen by fleas. The hmsHFRS operons is responsible for the synthesis of exopolysaccharide (the major component of biofilm matrix, which is activated by the signaling molecule 3', 5'-cyclic diguanylic acid (c-di-GMP synthesized by the only two diguanylate cyclases HmsT, and YPO0449 (located in a putative operonYPO0450-0448. METHODOLOGY/PRINCIPAL FINDINGS: The phenotypic assays indicated that the transcriptional regulator Fur inhibited the Y. pestis biofilm production in vitro and on nematode. Two distinct Fur box-like sequences were predicted within the promoter-proximal region of hmsT, suggesting that hmsT might be a direct Fur target. The subsequent primer extension, LacZ fusion, electrophoretic mobility shift, and DNase I footprinting assays disclosed that Fur specifically bound to the hmsT promoter-proximal region for repressing the hmsT transcription. In contrast, Fur had no regulatory effect on hmsHFRS and YPO0450-0448 at the transcriptional level. The detection of intracellular c-di-GMP levels revealed that Fur inhibited the c-di-GMP production. CONCLUSIONS/SIGNIFICANCE: Y. pestis Fur inhibits the c-di-GMP production through directly repressing the transcription of hmsT, and thus it acts as a repressor of biofilm formation. Since the relevant genetic contents for fur, hmsT, hmsHFRS, and YPO0450-0448 are extremely conserved between Y. pestis and typical Y. pseudotuberculosis, the above regulatory mechanisms can be applied to Y. pseudotuberculosis.

    Full Text Available This article makes use of digitized historic newspapers to analyze Newfoundland dog fur colour genetics, and fur colour variations over time. The results indicate that contrary to the accepted view, the ‘Solid’ gene was introduced into the British population of Newfoundland dogs in the 1840s. Prior to that time, the dogs were white and black (Landseer or white and brown, and thus spotted/spotted homozygotes. Due to ‘Solid’ being dominant over ‘spotted’, and selective breeding, today the majority of Newfoundland dogs are solid black. Whereas small white marks on the chest and/or paw appears to be a random event, the historical data supports the existence of an ‘Irish spotted’ fur colour pattern, with white head blaze, breast, paws and tail tip, in spotted/spotted homozygotes.

  9. The allosteric behavior of Fur mediates oxidative stress signal transduction in Helicobacter pylori

    Directory of Open Access Journals (Sweden)

    Simone ePelliciari

    2015-08-01

    Full Text Available The microaerophilic gastric pathogen Helicobacter pylori is exposed to oxidative stress originating from the aerobic environment, the oxidative burst of phagocytes and the formation of reactive oxygen species, catalyzed by iron excess. Accordingly, the expression of genes involved in oxidative stress defense have been repeatedly linked to the ferric uptake regulator Fur. Moreover, mutations in the Fur protein affect the resistance to metronidazole, likely due to loss-of-function in the regulation of genes involved in redox control. Although many advances in the molecular understanding of HpFur function were made, little is known about the mechanisms that enable Fur to mediate the responses to oxidative stress.Here we show that iron-inducible, apo-Fur repressed genes, such as pfr and hydA, are induced shortly after oxidative stress, while their oxidative induction is lost in a fur knockout strain. On the contrary, holo-Fur repressed genes, such as frpB1 and fecA1, vary modestly in response to oxidative stress. This indicates that the oxidative stress signal specifically targets apo-Fur repressed genes, rather than impairing indiscriminately the regulatory function of Fur. Footprinting analyses showed that the oxidative signal strongly impairs the binding affinity of Fur towards apo-operators, while the binding towards holo-operators is less affected. Further evidence is presented that a reduced state of Fur is needed to maintain apo-repression, while oxidative conditions shift the preferred binding architecture of Fur towards the holo-operator binding conformation, even in the absence of iron. Together the results demonstrate that the allosteric regulation of Fur enables transduction of oxidative stress signals in H. pylori, supporting the concept that apo-Fur repressed genes can be considered oxidation inducible Fur regulatory targets. These findings may have important implications in the study of H. pylori treatment and resistance to

    A comparison of the measured and simulated values of three collector types shows that evacuated tube collectors are superior to transparent-insulation flat collectors in the case of high-temperature uses. At temperatures of 150 C and above good results were obtained using evacuated tube collectors with compound parabolic concentrators manufactured by Microtherm. CORTEC collectors are suited for temperatures in the range of 100 C to 150 C provided that the surface ratio is irrelevant. Costs play a decisive role when selecting systems. The results obtained show that improved transparent-insulation flat collectors can compete with evacuated tube collectors in the 100 C to 150 C temperature range. (orig.)

    A retrospective cohort mortality study was conducted on 807 fur dyers, fur dressers (tanners), and fur service workers who were pensioned between 1952 and 1977 by the Fur, Leather and Machine Workers Union of New York City. Workplace exposures of fur workers varied with job category. Dyers were exposed to oxidative dyes used in commercial hair dyes; dressers and service workers were exposed to tanning chemicals. In a comparison with the New York City population, no significant increases in mortality were observed among the fur dyers. Among fur dressers, mortality from all malignant neoplasms and lung cancer was significantly elevated, as was mortality from cardiovascular disease among fur service workers. When examined by ethnic origin, the elevated SMR values and directly age-adjusted rate ratios suggested that foreign-born fur dressers and eastern European-born fur workers experienced the highest risks for lung and colorectal cancers, respectively. These data support previous findings of increased mortality from colorectal cancer in the foreign-born population of the United States and suggest a possible occupational etiology for the observed lung cancer excess.

    Previous experiments examining the transcriptional profileof the anaerobe Desulfovibrio vulgaris demonstrated up-regulation of theFur regulon in response to various environmental stressors. To test theinvolvement of Fur in the growth response and transcriptional regulationof D. vulgaris, a targeted mutagenesis procedure was used for deletingthe fur gene. Growth of the resulting ?fur mutant (JW707) was notaffected by iron availability, but the mutant did exhibit increasedsensitivity to nitrite and osmotic stresses compared to the wild type.Transcriptional profiling of JW707 indicated that iron-bound Fur acts asa traditional repressor for ferrous iron uptake genes (feoAB) and othergenes containing a predicted Fur binding site within their promoter.Despite the apparent lack of siderophore biosynthesis genes within the D.vulgaris genome, a large 12-gene operon encoding orthologs to TonB andTolQR also appeared to be repressed by iron-bound Fur. While other genespredicted to be involved in iron homeostasis were unaffected by thepresence or absence of Fur, alternative expression patterns that could beinterpreted as repression or activation by iron-free Fur were observed.Both the physiological and transcriptional data implicate a globalregulatory role for Fur in the sulfate-reducing bacterium D.vulgaris.

  5. A single nucleotide change affects fur-dependent regulation of sodB in H. pylori.

    Directory of Open Access Journals (Sweden)

    Beth M Carpenter

    Full Text Available Helicobacter pylori is a significant human pathogen that has adapted to survive the many stresses found within the gastric environment. Superoxide Dismutase (SodB is an important factor that helps H. pylori combat oxidative stress. sodB was previously shown to be repressed by the Ferric Uptake Regulator (Fur in the absence of iron (apo-Fur regulation [1]. Herein, we show that apo regulation is not fully conserved among all strains of H. pylori. apo-Fur dependent changes in sodB expression are not observed under iron deplete conditions in H. pylori strains G27, HPAG1, or J99. However, Fur regulation of pfr and amiE occurs as expected. Comparative analysis of the Fur coding sequence between G27 and 26695 revealed a single amino acid difference, which was not responsible for the altered sodB regulation. Comparison of the sodB promoters from G27 and 26695 also revealed a single nucleotide difference within the predicted Fur binding site. Alteration of this nucleotide in G27 to that of 26695 restored apo-Fur dependent sodB regulation, indicating that a single base difference is at least partially responsible for the difference in sodB regulation observed among these H. pylori strains. Fur binding studies revealed that alteration of this single nucleotide in G27 increased the affinity of Fur for the sodB promoter. Additionally, the single base change in G27 enabled the sodB promoter to bind to apo-Fur with affinities similar to the 26695 sodB promoter. Taken together these data indicate that this nucleotide residue is important for direct apo-Fur binding to the sodB promoter.

    Novel members of the bacterial genus Brucella have recently emerged as pathogens of various marine mammal species and as potential zoonotic agents. We investigated the epizootiology of Brucella infection in Australian fur seals (Arctocephalus pusillus doriferus) by establishing demographic and temporal variations in antibody prevalence, attempting isolation of the causative agent, and determining whether this potential pathogen is involved in frequent abortions observed in this pinniped species. Two competitive enzyme-linked immunosorbent assays (cELISAs), an indirect ELISA, and a fluorescence polarization assay (FPA) were used to test sera for Brucella antibodies. The FPA and cELISA proved suitable for use in this species. Significant differences in antibody prevalence were found between age classes of seals sampled between 2007 and 2009 at one colony. Pups sampled at this site (n=134) were negative for Brucella antibodies by all serologic tests but 17 of 45 (38%) of juveniles were antibody-positive. Antibody prevalence in adult females was significantly higher than in juveniles (P=0.044). Antibody prevalence for adult females between 2003 and 2009 varied significantly over time (P=0.011), and for individuals sampled between 2003 and 2005, the likelihood of pregnancy was greater in individuals positive for Brucella antibodies (P=0.034). Inflammatory lesions suggestive of infectious agents were found in 14 of 39 aborted Australian fur seal pups, but pathologic changes were not uniformly consistent for Brucella infection. Culture and PCR investigations on fetal tissues were negative for Brucella. Culture and PCR on selected fresh or frozen tissues from 36 juvenile and adult animals were also negative. We suspect that the prevalence of active infection with Brucella in Australian fur seals is low relative to antibody prevalence.

    Lyons, E T; DeLong, R L; Melin, S R; Tolliver, S C

    1997-10-01

    Northern fur seal (Callorhinus ursinus) (n = 25) and California sea lion (Zalophus californianus) (n = 53) pups, found dead on rookeries on San Miguel Island (California, USA), were examined for adult Uncinaria spp. Prevalence of these nematodes was 96% in fur seal pups and 100% in sea lion pups. Mean intensity of Uncinaria spp. per infected pup was 643 in fur seals and 1,284 in sea lions. Eggs of Uncinaria spp. from dead sea lion pups underwent embryonation in an incubator; development to the free-living third stage larva occurred within the egg. This study provided some specific information on hookworm infections in northern fur seal and California sea lion pups on San Miguel Island. High prevalence rate of Uncinaria spp. in both species of pinnipeds was documented and much higher numbers (2X) of hookworms were present in sea lion than fur seal pups.

  13. Bacillus licheniformis Contains Two More PerR-Like Proteins in Addition to PerR, Fur, and Zur Orthologues.

    Full Text Available The ferric uptake regulator (Fur family proteins include sensors of Fe (Fur, Zn (Zur, and peroxide (PerR. Among Fur family proteins, Fur and Zur are ubiquitous in most prokaryotic organisms, whereas PerR exists mainly in Gram positive bacteria as a functional homologue of OxyR. Gram positive bacteria such as Bacillus subtilis, Listeria monocytogenes and Staphylococcus aureus encode three Fur family proteins: Fur, Zur, and PerR. In this study, we identified five Fur family proteins from B. licheniformis: two novel PerR-like proteins (BL00690 and BL00950 in addition to Fur (BL05249, Zur (BL03703, and PerR (BL00075 homologues. Our data indicate that all of the five B. licheniformis Fur homologues contain a structural Zn2+ site composed of four cysteine residues like many other Fur family proteins. Furthermore, we provide evidence that the PerR-like proteins (BL00690 and BL00950 as well as PerRBL (BL00075, but not FurBL (BL05249 and ZurBL (BL03703, can sense H2O2 by histidine oxidation with different sensitivity. We also show that PerR2 (BL00690 has a PerR-like repressor activity for PerR-regulated genes in vivo. Taken together, our results suggest that B. licheniformis contains three PerR subfamily proteins which can sense H2O2 by histidine oxidation not by cysteine oxidation, in addition to Fur and Zur.

    1998-03-01

    The Three Gorges Project on the Yangtse River is one of the biggest hydraulic engineering projects ever. Its objectives are threefold: Improve flood control for a region with a population of several millions of people, generate power of an order of magnitude comparable to the output of ten nuclear power plants, and improve the navigability of China`s most important waterway. Just as any other big, international hydraulic engineering project, this one, too, has raised a storm of protest from opponents. Primarily the re-settlement of 1.3 million of people and aspects of the structural stability of the dam and related hazards are issues of controversy. In the eyes of the author of this article, opponents in the western hemisphere are drawing a far too gloomy picture in their rejection of the project. (orig./CB) [Deutsch] Das `Drei-Schluchten-Projekt` am Jangtse ist eines der anspruchsvollsten Wasserbauvorhaben, die je in Angriff genommen wurden. Es soll drei Zwecke erfuellen: Verbesserten Hochwasserschutz fuer Millionen von Menschen, Stromerzeugung in der Groessenordnung von zehn Kernkraftwerken sowie Erleichterung der Schiffahrt auf Chinas wichtigster Wasserstrasse. Wie wohl jedes internationale Wasserbauprojekt hat auch dieses gewaltige Vorhaben Protest bei Gegnern weltweit hervorgerufen. Insbesondere die erforderliche Umsiedlung von 1,3 Millionen Menschen und die Frage der Staumauersicherheit werden heftigst kritisiert bzw. angezweifelt. Mit der Verteufelung des Projektes schiessen die Anti-Staudamm-Gruppen aus dem Westen aber weit uebers Ziel hinaus. (orig./RHM)

  16. Drei Avantgarde-Strömungen des heutigen US-Geisteslebens – und ihre Beziehung zu Europa

    Directory of Open Access Journals (Sweden)

    Roland Benedikter

    2006-12-01

    Full Text Available Zusammenfassung: Die heutigen USA gelten vielen als Vorreiter auf dem Weg zur integrativen Erneuerung von Wissenschafts- und Erkenntnisparadigmen. Dies vor allem im Bereich der traditionellen Kern- und Grundlagen-Wissenschaft der neuzeitlichen Universität: der Philosophie und der historisch aus ihr erwachsenen Psychologien. Seit einigen Jahren ist in den USA in der Tat eine Entwicklung im Gang, welche die Einseitigkeiten des nominalistisch-subjektivistischen Paradigmas der „Postmoderne“, welches aus ideengeschichtlicher Sicht die Epoche zwischen 1979 und 2001 geprägt hat, um einen neuen geistigen Objektivismus ausgleichen und beide zu einem neuen, „subjektiv-objektiven“ Paradigma integrieren will. Diese Entwicklung findet ihren Ausdruck in drei exemplarischen Avantgarde-Strömungen, die im vorliegenden Beitragvorgestellt sowie auf Charakteristiken und Wechselbeziehungen untersucht werden. Dabei erweist sich, dass die heutige ideengeschichtliche Avantgarde der USA in Kernterminologie, historischer Kontinuität und Ausrichtung stark pazifisch-asiatisch, aber noch zu wenig atlantisch-europäisch geprägt ist. Das scheint mit ein Grund dafür zu sein, warum diese Avantgarde-Ansätze trotz ihres hochwertigen Anregungs- und Innovations-Potentials im Hinblick auf ein ganzheitlichen Wissenschafts-Paradigma für das 21. Jahrhundert noch unübersehbare Schwierigkeiten haben, den atlantisch-europäisch geprägten Hauptstrom des Geistes-, Kultur- und politisch-sozialen Lebens ihrer Gesellschaft zu erreichen. Es zeigt sich, dass der innere Ausgleich zwischen pazifischen und atlantischen Ideen-Einflüssen eine der zentralen Herausforderungen für diese Avantgarde-Strömungen, aber darüber hinaus im Spiegelverhältnis auch für das europäische Kultur- und Gesellschafts-Paradigma sowie für die Entwicklung der integralen Bewegungen auf Weltebene insgesamt ist.

  17. Barrels of fur: Natural resources and the state in the long history of Russia

    Directory of Open Access Journals (Sweden)

    Alexander Etkind

    2011-07-01

    Full Text Available This article argues that in its enormous Northern and Eastern stretches, the geographical space of Russia was shaped by the fur trade. The essay follows the boom and depletion of the fur trade in the longue durée of Russian history. The fur trade brought many Northern tribes to the edge of extermination. Hunting and trapping was intrinsically violent, did not entail the long-term cycles that were characteristic for agriculture, and needed no participation from women. It also created the situation that some historians called the hyper-activity of the state. The resource-bound economy made the population largely superfluous. The essay also explores the historiography of the fur trade and the debates that this historiography saw in the 1920s. Finally, it draws an analogy between two resource-bound epochs, the pre-modern dependency of the Russian state on fur and its modern dependency on oil. Very little part of the population took part in the fur business, with the result that the state did not care about the population and the population did not care about the state. A caste-like society emerges in these conditions. The security apparatus becomes identical to the state. Due to a chance of history or geography, the same areas that fed the fur trade of medieval Novgorod and Moscow, have provided the Soviet Union and post-Soviet Russia with their means for existence.

  18. Metagenomic Survey of Viral Diversity Obtained from Feces of Subantarctic and South American Fur Seals.

    Mariana Kluge

    Full Text Available The Brazilian South coast seasonally hosts numerous marine species, observed particularly during winter months. Some animals, including fur seals, are found dead or debilitated along the shore and may harbor potential pathogens within their microbiota. In the present study, a metagenomic approach was performed to evaluate the viral diversity in feces of fur seals found deceased along the coast of the state of Rio Grande do Sul. The fecal virome of two fur seal species was characterized: the South American fur seal (Arctocephalus australis and the Subantarctic fur seal (Arctocephalus tropicalis. Fecal samples from 10 specimens (A. australis, n = 5; A. tropicalis, n = 5 were collected and viral particles were purified, extracted and amplified with a random PCR. The products were sequenced through Ion Torrent and Illumina platforms and assembled reads were submitted to BLASTx searches. Both viromes were dominated by bacteriophages and included a number of potentially novel virus genomes. Sequences of picobirnaviruses, picornaviruses and a hepevirus-like were identified in A. australis. A rotavirus related to group C, a novel member of the Sakobuvirus and a sapovirus very similar to California sea lion sapovirus 1 were found in A. tropicalis. Additionally, sequences of members of the Anelloviridae and Parvoviridae families were detected in both fur seal species. This is the first metagenomic study to screen the fecal virome of fur seals, contributing to a better understanding of the complexity of the viral community present in the intestinal microbiota of these animals.

    New Zealand white rabbit pelts were pickled by the usual procedure and were tanned with basic aluminium sulphate, basic chromium sulphate and their combinations. Tanned furs were irradiated with 60 Co-gamma radiations in the dose range of 5.0-114.0 kGy. The effect of radiation on the binding properties of various added substances like mineral tannins, fats, moisture and shrinkage temperature has been assessed by their comparison with the control samples. The results of these investigations show that radiation on furs causes detannage, increases the moisture and bound fat content and decreases the shrinkage temperature of the furs. (author)

  1. A memory like a female Fur Seal: long-lasting recognition of pup's voice by mothers.

    Science.gov (United States)

    Mathevon, Nicolas; Charrier, Isabelle; Aubin, Thierry

    2004-06-01

    In colonial mammals like fur seals, mutual vocal recognition between mothers and their pup is of primary importance for breeding success. Females alternate feeding sea-trips with suckling periods on land, and when coming back from the ocean, they have to vocally find their offspring among numerous similar-looking pups. Young fur seals emit a 'mother-attraction call' that presents individual characteristics. In this paper, we review the perceptual process of pup's call recognition by Subantarctic Fur Seal Arctocephalus tropicalis mothers. To identify their progeny, females rely on the frequency modulation pattern and spectral features of this call. As the acoustic characteristics of a pup's call change throughout the lactation period due to the growing process, mothers have thus to refine their memorization of their pup's voice. Field experiments show that female Fur Seals are able to retain all the successive versions of their pup's call.

    A female South African fur seal (Arctocephalus pusillus pusillus) began having obvious clinical ophthalmologic problems by 8 weeks of age. The initial clinical sign was diffuse corneal edema, which progressed to bullae formation and ulcers; the underlying cause of corneal edema and bullous...... keratopathy was not identified antemortem. An ophthalmological evaluation was performed when the fur seal was approximately 6 months of age, but due to the diffuse corneal edema, intraocular structures could not be easily evaluated. An underlying infectious etiology was suspected; therefore, appropriate...... diagnostics were pursued, but did not identify a cause. Initial improvement was noted, but the fur seal then became blind and eventually became very painful. Due to decreased quality of life and aggressive behavior, the fur seal was euthanized.

  10. Distribution of mercury in archived fur from little brown bats across Atlantic Canada

    Little, Megan E.; Burgess, Neil M.; Broders, Hugh G.; Campbell, Linda M.

    2015-01-01

    Total mercury (Hg) concentrations were measured in archived fur from adult female little brown bats sampled at maternity roosts across Atlantic Canada. Mercury concentrations varied significantly among regions and roosts. Bats from Nova Scotia and Newfoundland had the highest median Hg concentrations (9.67 μg/g and 9.51 μg/g) among regions, and individuals from Kejimkujik National Park had the highest Hg (median: 28.38 μg/g) among roosts. Over one third of individuals sampled had fur Hg concentrations exceeding thresholds associated with neurochemical responses. Within-roost examinations of stable carbon and nitrogen isotopes in fur showed inconsistent associations with Hg concentrations. Therefore, the hypothesis that within-roost variation in Hg is driven by variation in diet is not supported by this data, and it is recommended that key prey items be included in future mercury bioaccumulation studies for bats. The elevated mercury fur concentrations for bats from southern Nova Scotia remains an anomaly of concern even when placed in the larger context of Atlantic Canada. - Highlights: • Nova Scotia and Newfoundland bats had the highest median Hg values in fur among regions. • Median maternity roost fur Hg concentrations were highest in Kejimkujik, Nova Scotia. • Hg concentrations in 37% of bats exceeded the threshold for neurochemical responses. • Within-roost variations in carbon and nitrogen stable isotopes do not match Hg trends.

  11. Use of electrochemically activated aqueous solutions in the manufacture of fur materials.

    2016-01-01

    The influence of characteristics of electrochemically activated aqueous processing mediums in the treatment of fur skins with different contents of fatty substances was investigated. The use of electroactive water, namely anolytes and catholytes, forgoing antiseptics or surface-active materials, helped to restore the hydration of fur skins and to remove from them soluble proteins, carbohydrates and fatty substances. The activating effect of anolyte and catholyte in solutions of water on the processes of treating raw furs is explained by their special physical and chemical properties, namely the presence of free radicals, ions and molecules of water which easily penetrate cells' membranes and into the structure of non-collagen components and microfiber structure of dermic collagen. The stage of lengthy acid and salt treatment is excluded from the technical treatment as a result of using electroactivated water with high oxidizing power. A low-cost technology of processing different kinds of fur with the use of electroactivated water provides for substantial economy of water and chemical reagents, a two to threefold acceleration of the soaking and tanning processes and creation of highly elastic fur materials with a specified set of physical and chemical properties. At the same time the technology of preparatory processes of fur treatment excludes the use of such toxic antiseptics as formalin and sodium silicofluoride, which gives grounds to regard it as ecologically safe.

  12. Fukushima derived radiocesium in subsistence-consumed northern fur seal and wild celery

    Ruedig, Elizabeth; Duncan, Colleen; Dickerson, Bobette; Williams, Michael; Gelatt, Thomas; Bell, Justin; Johnson, Thomas E.

    2016-01-01

    In July 2014, our investigative team traveled to St. Paul Island, Alaska to measure concentrations of radiocesium in wild-caught food products, primarily northern fur seal (Callorhinus ursinus). The 2011 Fukushima Daiichi Nuclear Power Plant accident released radiocesium into the atmosphere and into the western Pacific Ocean; other investigators have detected Fukushima-derived radionuclides in a variety of marine products harvested off the western coast of North America. We tested two subsistence-consumed food products from St. Paul Island, Alaska for Fukushima-derived radionuclides: 54 northern fur seal, and nine putchki (wild celery, Angelica lucida) plants. Individual northern fur seal samples were below minimum detectable activity concentrations of "1"3"7Cs and "1"3"4Cs, but when composited, northern fur seal tissues tested positive for trace quantities of both isotopes. Radiocesium was detected at an activity concentration of 37.2 mBq "1"3"4Cs kg"−"1 f.w. (95% CI: 35.9–38.5) and 141.2 mBq "1"3"7Cs kg"−"1 f.w. (95% CI: 135.5–146.8). The measured isotopic ratio, decay-corrected to the date of harvest, was 0.26 (95% CI: 0.25–0.28). The Fukushima nuclear accident released "1"3"4Cs and "1"3"7Cs in roughly equal quantities, but by the date of harvest in July 2014, this ratio was 0.2774, indicating that this population of seals has been exposed to small quantities of Fukushima-derived radiocesium. Activity concentrations of both "1"3"4Cs and "1"3"7Cs in putchki were below detection limits, even for composited samples. Northern fur seal is known to migrate between coastal Alaska and Japan and the trace "1"3"4Cs in northern fur seal tissue suggests that the population under study had been minimally exposed Fukushima-derived radionuclides. Despite this inference, the radionuclide quantities detected are small and no impact is expected as a result of the measured radiation exposure, either in northern fur seal or human populations consuming this species

    2017-01-01

    An Introduction to the Study of Variable Stars by Dr. Caroline Ellen Furness (1869-1936), Director of the Vassar College Observatory, was published in October 2015. Issued in honor of the fiftieth anniversary of the founding of Vassar College, the work was meant to fill a void in the literature, namely as both an introduction to the topic of variable stars as well as a manual explaining how they should be observed and the resulting data analyzed. It was judged to be one of the hundred best books written by an American woman in the last hundred years at the 1933 World’s Fair in Chicago. The book covers the relevant history of and background on types of variable stars, star charts, catalogs, and the magnitude scale, then describes observing techniques, including visual, photographic, and photoelectric photometry. The work finishes with a discussion of light curves and patterns of variability, with a special emphasis on eclipsing binaries and long period variables. Furness’s work is therefore a valuable snapshot of the state of astronomical knowledge, technology, and observing techniques from a century ago. Furness’s book and its reception in the scientific community are analyzed, and parallels with (and departures from) the current advice given by the AAVSO to beginning variable star observers today are highlighted.

    Full Text Available We report observations on fur-rubbing with leaves from Piper aduncum by a San Martín titi monkey, Callicebus oenanthe. Fur-rubbing occurred during the transition from the dry to the rainy season in a titi monkey group living in a forest fragment in the Moyobamba region of Peru. Since Piper leaves include very potent compounds that may affect ectoparasites, we tentatively interpret the observed fur-rubbing as self-medication.

    2008-01-01

    Seismic isolation is an effective design strategy to mitigate the seismic hazard wherein the structure and its contents are protected from the damaging effects of an earthquake. This paper presents the Hangar Project in Sabiha Goekcen Airport which is located in Istanbul, Turkey. Seismic isolation system where the isolation layer arranged at the top of the columns is selected. The seismic hazard analysis, superstructure design, isolator design and testing were based on the Uniform Building Code (1997) and met all requirements of the Turkish Earthquake Code (2007). The substructure which has the steel vertical trusses on facades and RC H shaped columns in the middle axis of the building was designed with an R factor limited to 2.0 in accordance with Turkish Earthquake Code. In order to verify the effectiveness of the isolation system, nonlinear static and dynamic analyses are performed. The analysis revealed that isolated building has lower base shear (approximately 1/4) against the non-isolated structure

    1995-01-01

    NASA's two-seat F-16XL research aircraft is shown in the modification hangar at the Dryden Flight Research Center, Edwards, California, during installation of a titanium 'glove' on the upper surface of its modified left wing. The aircraft subsequently concluded a 13 month-long, 45-flight research program which investigated drawing off a small portion of the boundary-layer air in order to provide laminar -- or smooth -- flow over a major portion of a wing flying at supersonic speeds. A turbo-compressor in the aircraft's fuselage provided suction to draw air through more than 10 million tiny laser-drilled holes in the glove via a manifold system employing 20 valves. Data obtained during the program could assist designers of future high-speed aircraft in developing a more efficient civil transport.

    Galeano, María G; Cantarelli, Verónica I; Ruiz, Rubén D; Fiol de Cuneo, Marta; Ponzio, Marina F

    2014-09-01

    In captive chinchillas, one of the most challenging behavioral problems is the development of a stress-related abnormal repetitive behavior (ARB) known as "fur-chewing". We investigated whether there is a relationship between the severity of fur-chewing behavior and reproductive function in male and female chinchillas. Regardless of the severity of abnormal behavior, fur-chewing males did not show significant differences in seminal quality (sperm concentration, motility and viability; integrity of sperm membrane and acrosome) and the response to the process of semen collection (the number of stimuli needed to achieve ejaculation) when compared to those with normal behavior. Also, females showing normal or fur-chewing behavior presented similar reproductive performance in terms of number of litters per female per year and litter size. However, pup survival rate was lower (p=0.05) in fur-chewing females than in normal females. These results seem to be consistent with data suggesting non-significant effects of ARBs on reproductive performance.

  18. The behavioural response of Australian fur seals to motor boat noise.

    Joy S Tripovich

    Full Text Available Australian fur seals breed on thirteen islands located in the Bass Strait, Australia. Land access to these islands is restricted, minimising human presence but boat access is still permissible with limitations on approach distances. Thirty-two controlled noise exposure experiments were conducted on breeding Australian fur seals to determine their behavioural response to controlled in-air motor boat noise on Kanowna Island (39°10'S, 146°18'E. Our results show there were significant differences in the seals' behaviour at low (64-70 dB versus high (75-85 dB sound levels, with seals orientating themselves towards or physically moving away from the louder boat noise at three different sound levels. Furthermore, seals responded more aggressively with one another and were more alert when they heard louder boat noise. Australian fur seals demonstrated plasticity in their vocal responses to boat noise with calls being significantly different between the various sound intensities and barks tending to get faster as the boat noise got louder. These results suggest that Australian fur seals on Kanowna Island show behavioural disturbance to high level boat noise. Consequently, it is recommended that an appropriate level of received boat sound emissions at breeding fur seal colonies be below 74 dB and that these findings be taken into account when evaluating appropriate approach distances and speed limits for boats.

    In this study silk-floss and dog fur were tested as sorbent materials for oils and the results were compared with peat, a commercial sorbent. Sorption tests were carried out in dry and aqueous systems, with and without stirring for different periods of time (5-1440 min). Density, hydrophobicity, buoyancy and water uptake by the fibers of the impregnated sorbents have been determined. The use of silk-floss and dog fur was also tested in columns to purify water containing toluene, benzene, motor oil or sunflower oil. Breakthrough curves during 120 min were drawn for each material with the samples (oily water or water containing benzene or toluene) and were analyzed by ultraviolet spectroscopy. It was concluded that the silk-floss is the best sorbent material (65.3 g oil/g sorbent) followed by the dog fur (34.6 g oil/g sorbent) and peat (19.5 g oil/g sorbent), for sorption time of 1 h in dynamic condition. The efficiency of the pollutant removal from water with the use of adsorption columns was high for both materials although the use of dog fur was preferable because of the slight superiority in efficiency compared to silk-floss and also, due to the easier packing of the dog fur in the column.

    To characterise mercury (Hg) exposure in Daubenton's bat (Myotis daubentonii, Kuhl 1817) in southern Sweden, 17 specimens were captured in 2013 and back fur samples were taken for analysis to determine Hg concentrations. The fur Hg levels determined [1.15 ± 0.27 (mean ± standard deviation, n = 17) µg Hg g -1 fresh weight (fw)] represent a baseline for comparison in future assessments of Hg exposure in bat populations in northern Europe. Mercury concentrations were close to those reported in fur from other bat species, but were lower than proposed toxicological thresholds in bats (> 30 µg Hg g -1  fw) and mice (5 µg Hg g -1  fw). This is the first study to examine Hg exposure in bats in Scandinavia.

    The colostrum trypsin inhibitor (CTI) gene and transcript were cloned from the Cape fur seal mammary gland and CTI identified by in silico analysis of the Pacific walrus and polar bear genomes (Order Carnivora), and in marine and terrestrial mammals of the Orders Cetartiodactyla (yak, whales, camel) and Perissodactyla (white rhinoceros). Unexpectedly, Weddell seal CTI was predicted to be a pseudogene. Cape fur seal CTI was expressed in the mammary gland of a pregnant multiparous seal, but not in a seal in its first pregnancy. While bovine CTI is expressed for 24-48 h postpartum (pp) and secreted in colostrum only, Cape fur seal CTI was detected for at least 2-3 months pp while the mother was suckling its young on-shore. Furthermore, CTI was expressed in the mammary gland of only one of the lactating seals that was foraging at-sea. The expression of β-casein (CSN2) and β-lactoglobulin II (LGB2), but not CTI in the second lactating seal foraging at-sea suggested that CTI may be intermittently expressed during lactation. Cape fur seal and walrus CTI encode putative small, secreted, N-glycosylated proteins with a single Kunitz/bovine pancreatic trypsin inhibitor (BPTI) domain indicative of serine protease inhibition. Mature Cape fur seal CTI shares 92% sequence identity with Pacific walrus CTI, but only 35% identity with BPTI. Structural homology modelling of Cape fur seal CTI and Pacific walrus trypsin based on the model of the second Kunitz domain of human tissue factor pathway inhibitor (TFPI) and porcine trypsin (Protein Data Bank: 1TFX) confirmed that CTI inhibits trypsin in a canonical fashion. Therefore, pinniped CTI may be critical for preventing the proteolytic degradation of immunoglobulins that are passively transferred from mother to young via colostrum and milk.

    The Fe2+-dependent Fur protein serves as a negative regulator of iron uptake in bacteria. As only metallo-Fur acts as an autogeneous repressor, Fe2+scarcity would direct fur expression when continued supply is not obviously required. We show that in Escherichia coli post-transcriptional regulatory mechanisms ensure that Fur synthesis remains steady in iron limitation. Our studies revealed that fur translation is coupled to that of an upstream open reading frame (uof), translation of which is downregulated by the non-coding RNA (ncRNA) RyhB. As RyhB transcription is negatively controlled by metallo-Fur, iron depletion creates a negative feedback loop. RyhB-mediated regulation of uof-fur provides the first example for indirect translational regulation by a trans-encoded ncRNA. In addition, we present evidence for an iron-responsive decoding mechanism of the uof-fur entity. It could serve as a backup mechanism of the RyhB circuitry, and represents the first link between iron availability and synthesis of an iron-containing protein.

  8. On the nature of fur evolution: A phylogenetic approach in Actinobacteria

    Directory of Open Access Journals (Sweden)

    Benson David R

    2008-06-01

    Full Text Available Abstract Background An understanding of the evolution of global transcription regulators is essential for comprehending the complex networks of cellular metabolism that have developed among related organisms. The fur gene encodes one of those regulators – the ferric uptake regulator Fur – widely distributed among bacteria and known to regulate different genes committed to varied metabolic pathways. On the other hand, members of the Actinobacteria comprise an ecologically diverse group of bacteria able to inhabit various natural environments, and for which relatively little is currently understood concerning transcriptional regulation. Results BLAST analyses revealed the presence of more than one fur homologue in most members of the Actinobacteria whose genomes have been fully sequenced. We propose a model to explain the evolutionary history of fur within this well-known bacterial phylum: the postulated scenario includes one duplication event from a primitive regulator, which probably had a broad range of co-factors and DNA-binding sites. This duplication predated the appearance of the last common ancestor of the Actinobacteria, while six other duplications occurred later within specific groups of organisms, particularly in two genera: Frankia and Streptomyces. The resulting paralogues maintained main biochemical properties, but became specialised for regulating specific functions, coordinating different metal ions and binding to unique DNA sequences. The presence of syntenic regions surrounding the different fur orthologues supports the proposed model, as do the evolutionary distances and topology of phylogenetic trees built using both Neighbor-Joining and Maximum-Likelihood methods. Conclusion The proposed fur evolutionary model, which includes one general duplication and two in-genus duplications followed by divergence and specialization, explains the presence and diversity of fur genes within the Actinobacteria.

    2017-08-03

    In 2007, a previously unrecorded disease, fur animal epidemic necrotic pyoderma (FENP), was detected in farmed mink (Neovision vision), foxes (Vulpes lagopus) and Finnraccoons (Nyctereutes procyonoides) in Finland. Symptoms included severe pyoderma with increased mortality, causing both animal welfare problems and economic losses. In 2011, an epidemiologic questionnaire was mailed to all members of the Finnish Fur Breeders' Association to assess the occurrence of FENP from 2009 through the first 6 months of 2011. The aim was to describe the geographical distribution and detailed clinical signs of FENP, as well as sources of infection and potential risk factors for the disease. A total of 239 farmers (25%) returned the questionnaire. Clinical signs of FENP were observed in 40% (95% CI 34-46%) of the study farms. In addition, the survey clarified the specific clinical signs for different animal species. The presence of disease was associated with the importation of mink, especially from Denmark (OR 9.3, 95% CI 2.6-33.0). The transmission route between Finnish farms was associated with fur animal purchases. Some risk factors such as the farm type were also indicated. As such, FENP was detected more commonly on farms with more than one species of fur animal in comparison to farms with, for example, only foxes (OR 4.6, 95% CI 2.4-8.6), and the incidence was higher on farms with over 750 breeder mink compared to smaller farms (OR 3.8, 95% CI 1.6-9.0). Contact between fur animals and birds and other wildlife increased the risk of FENP on farms. Responses also indicated that blocking the entry of wildlife to the animal premises protected against FENP. FENP was most likely introduced to Finland by imported mink and spread further within the country via domestically purchased fur animals. Some potential risk factors, such as the type and size of the farm and contact with wildlife, contributed to the spread of FENP. Escape-proof shelter buildings block the entry of wildlife

    Full Text Available Die heutigen USA gelten vielen als Vorreiter auf dem Weg zur integrativen Erneuerung von Wissenschafts- und Erkenntnisparadigmen. Dies vor allem im Bereich der traditionellen Kern- und Grundlagen-Wissenschaft der neuzeitlichen Universität: der Philosophie und der historisch aus ihr erwachsenen Psychologien. Seit einigen Jahren ist in den USA in der Tat eine Entwicklung im Gang, welche die Einseitigkeiten des nominalistisch-subjektivistischen Paradigmas der „Postmoderne“, welches aus ideengeschichtlicher Sicht die Epoche zwischen 1979 und 2001 geprägt hat, um einen neuen geistigen Objektivismus ausgleichen und beide zu einem neuen, „subjektiv-objektiven“ Paradigma integrieren will. Diese Entwicklung findet ihren Ausdruck in drei exemplarischen Avantgarde-Strömungen, die im vorliegenden Beitrag vorgestellt sowie auf Charakteristiken und Wechselbeziehungen untersucht werden. Dabei erweist sich, dass die heutige ideengeschichtliche Avantgarde der USA in Kernterminologie, historischer Kontinuität und Ausrichtung stark pazifisch-asiatisch, aber noch zu wenig atlantisch-europäisch geprägt ist. Das scheint mit ein Grund dafür zu sein, warum diese Avantgarde-Ansätze trotz ihres hochwertigen Anregungs- und Innovations-Potentials im Hinblick auf ein ganzheitliches Wissenschafts-Paradigma für das 21. Jahrhundert noch unübersehbare Schwierigkeiten haben, den atlantisch-europäisch geprägten Hauptstrom des Geistes-, Kultur- und politisch-sozialen Lebens ihrer Gesellschaft zu erreichen. Es zeigt sich, dass der innere Ausgleich zwischen pazifischen und atlantischen Ideen-Einflüssen eine der zentralen Herausforderungen für diese Avantgarde-Strömungen, aber darüber hinaus im Spiegelverhältnis auch für das europäische Kultur- und Gesellschafts-Paradigma sowie für die Entwicklung der integralen Bewegungen auf Weltebene insgesamt ist.

    The transport phase of the animal-mediated plant dispersal process is critical to dispersal effectiveness as it determines the spatial distribution of the diaspores released and their chance for further recruitment. Assessing this specific phase of the dispersal process generally requires combining diaspore retention times with the associated distances covered. Here, we specifically tested the effect of grooming behavior, interindividual contacts and ungulate fur on diaspore retention times and associated dispersal distances for the hooked diaspores of Xanthium strumarium L. experimentally attached to tamed individuals of three ungulate species. We used a comparative approach based on differing fur quality on different body zones of these three ungulates. During 6-hr sessions, we monitored for grooming and social interactions that may induce intended or inadvertent diaspore detachment. Additionally, we proposed innovative approaches to directly assessing diaspore dispersal distances by red deer in situ. Fat-tailed functions fitted diaspore retention time, highlighting the potential for long-distance dispersal events. The longer the hair, the higher the retention capacity of diaspores in the animal's fur. As predicted, donkey retained diaspores longer than red deer and dwarf goat; and we also confirmed that diaspores attached to the short hair of the head fell off more quickly than did those on the other body zones. Dwarf goat groomed more often than both red deer and donkey, but also when it carried diaspores. Up to 14% of the diaspores detached from animal fur after specific grooming behavior. We observed, in controlled conditions, for the first time and for each ungulate species, interindividual transfers of diaspores, representing 5% of the diaspores attached to animals' fur. Our results militate for incorporating animal behavior into plant dispersal modeling approaches.

  5. Coping with heat: function of the natal coat of cape fur seal (Arctocephalus Pusillus Pusillus pups in maintaining core body temperature.

    Directory of Open Access Journals (Sweden)

    Nicola Erdsack

    Full Text Available Cape fur seal (Arctocephalus pusillus pups spend the first weeks of life exclusively or mainly ashore. They are exposed to intense solar radiation and high temperatures for long time periods, which results in temperatures up to at least 80°C on their black natal coat. To test the hypothesis that the natal coat has a crucial function in coping with these extreme conditions, we investigated the insulating properties of the natal coat in six captive newborn Cape fur seals during the first 50 days after birth. The natal fur differs from the adult fur not only in colour, but also in density, structure, and water repellence. We measured temperature on the fur surface and within the fur, as well as skin and rectal temperature under varying environmental conditions, comparable to the species' habitat. Experiments were designed to not influence the spontaneous behaviour of the pups. Rectal temperature was constant as long as the pups stayed dry, even during long-lasting intense solar radiation for up to 3 h. Skin temperature remained close to rectal temperature as long as the fur was dry, while with wet fur, skin temperature was significantly reduced as well. Our results show that the natal coat provides an effective insulation against overheating. The severely reduced insulation of wet natal fur against cold supports the assumption that the natal fur is an adaptation to the pups' terrestrial phase of life.

    Flagellar motility of Helicobacter pylori has been shown to be important for the bacteria to establish initial colonization. The ferric uptake regulator (Fur) is a global regulator that has been identified in H. pylori which is involved in the processes of iron uptake and establishing colonization. However, the role of Fur in H. pylori motility is still unclear. Motility of the wild-type, fur mutant, and fur revertant J99 were determined by a soft-agar motility assay and direct video observation. The bacterial shape and flagellar structure were evaluated by transmission electron microscopy. Single bacterial motility and flagellar switching were observed by phase-contrast microscopy. Autoinducer-2 (AI-2) production in bacterial culture supernatant was analyzed by a bioluminescence assay. The fur mutant showed impaired motility in the soft-agar assay compared with the wild-type J99 and fur revertant. The numbers and lengths of flagellar filaments on the fur mutant cells were similar to those of the wild-type and revertant cells. Phenotypic characterization showed similar swimming speed but reduction in switching rate in the fur mutant. The AI-2 production of the fur mutant was dramatically reduced compared with wild-type J99 in log-phase culture medium. These results indicate that Fur positively modulates H. pylori J99 motility through interfering with bacterial flagellar switching. © 2017 John Wiley & Sons Ltd.

    Perfluorinated compounds (PFCs) have emerged as a new class of global environmental pollutants. In this study, the presence of perfluorochemicals (PFCs) in penguin eggs and Antarctic fur seals was reported for the first time. Tissue samples from Antarctic fur seal pups and penguin eggs were collected during the 2003/04 breeding season. Ten PFC contaminants were determined in seal and penguin samples. The PFC concentrations in seal liver were in the decreasing order, PFOS>PFNA>PFHpA>PFUnDA while in Adélie penguin eggs were PFHpA>PFUnDA>PFDA>PFDoDA, and in Gentoo penguin eggs were PFUnDA>PFOS>PFDoDA>PFHpA. The PFC concentrations differed significantly between seals and penguins (ppenguins (ppenguin eggs of 0.3 ng/g and 0.38 ng/g wet wt, respectively. PFCs detected in penguin eggs and seal pups suggested oviparous and viviparous transfer of PFOS to eggs and off-springs.

    The Bacillus subtilis ferric uptake regulator (Fur) protein mediates the iron-dependent repression of at least 20 operons encoding approximately 40 genes. We investigated the physiological roles of Fur-regulated genes by the construction of null mutations in 14 transcription units known or predicted to function in siderophore biosynthesis or iron uptake. We demonstrate that ywbLMN, encoding an elemental iron uptake system orthologous to the copper oxidase-dependent Fe(III) uptake system of Saccharomyces cerevisiae, is essential for growth in low iron minimal medium lacking citric acid. 2,3-Dihydroxybenzoyl-glycine (Itoic acid), the siderophore precursor produced by laboratory strains of B. subtilis, is of secondary importance. In the presence of citrate, the YfmCDEF ABC transporter is required for optimal growth. B. subtilis is unable to grow in minimal medium containing the iron chelator EDDHA unless the ability to synthesize the intact bacillibactin siderophore is restored (by the introduction of a functional sfp gene) or exogenous siderophores are provided. Utilization of the catecholate siderophores bacillibactin and enterobactin requires the FeuABC importer and the YusV ATPase. Utilization of hydroxamate siderophores requires the FhuBGC ABC transporter together with the FhuD (ferrichrome) or YxeB (ferrioxamine) substrate-binding proteins. Growth with schizokinen or arthrobactin is at least partially dependent on the YfhA YfiYZ importer and the YusV ATPase. We have also investigated the effects of a fur mutation on the proteome and documented the derepression of 11 Fur-regulated proteins, including a newly identified thioredoxin reductase homolog, YcgT.

    (Abstract only) A century and one month ago (October 1915) Dr. Caroline Ellen Furness (1869-1936), Director of the Vassar College Observatory, published An Introduction to the Study of Variable Stars. Issued in honor of the fiftieth anniversary of the founding of Vassar College, the work was meant to fill a void in the literature, namely as both an introduction to the topic of variable stars and as a manual explaining how they should be observed and the resulting data analyzed. It was judged to be one of the hundred best books written by an American woman in the last hundred years at the 1933 World's Fair in Chicago. The book covers the relevant history of and background on types of variable stars, star charts, catalogs, and the magnitude scale, then describes observing techniques, including visual, photographic, and photoelectric photometry. The work finishes with a discussion of light curves and patterns of variability, with a special emphasis on eclipsing binaries and long period variables. Furness's work is a valuable snapshot of the state of astronomical knowledge, technology, and observing techniques from a century ago. This presentation will analyze both Furness's book and its reception in the scientific community, and draw parallels to current advice given to beginning variable star observers.

  12. Sand Floor for Farmed Blue Foxes: Effects on Claws, Adrenal Cortex Function, Growth and Fur Properties

    Full Text Available Farmed blue foxes (Vulpes lagopus are traditionally housed on mesh floors where they are unable to perform certain species-specific behaviours, such as digging, which may compromise the animals' welfare. This study describes how a possibility to use in-cage sand floor affects welfare-related variables like growth of the claws, adrenal cortex function, and fur properties in juvenile blue foxes. The foxes (N=32 were housed in male-female sibling pairs in an outdoor fur animal shed in cage systems consisting of two traditional fox cages. For the eight male-female sibling pairs of the Control group, there was a mesh floor in both cages of each cage system, whereas for the eight pairs of the Sand group there was a mesh floor in one cage and a 30–40 cm deep earth floor in the other cage. The results show that sand floor is beneficial for the wearing of the claws of foxes. Furthermore, an early experience of sand floor may have positive effects on the foxes' fur development. The results, however, also suggest that there might appear welfare problems observed as disturbed claw growth and increased adrenal cortex activation if foxes that are once provided with clean and unfrozen sand floor are not allowed to enjoy this floor all the time.

    Full Text Available Timur Kouliev,1 Victoria Cui2 1Beijing United Family Hospital, Beijing, People's Republic of China; 2Department of Biological Sciences, Columbia University, New York, NY, USA Abstract: In recent decades, an increasing number of people have traveled to sub-Antarctic and Antarctic regions each year for research, tourism, and resource exploitation. Hunting of Antarctic fur seals (Arctocephalus gazella almost pushed the species to extinction in the early 1900s, but populations have since shown rapid and substantial recovery. The species' range has re-expanded to include several islands south of the Antarctic Convergence, most notably South Georgia, and now overlaps with many popular Antarctic travel destinations. Both male and female fur seals can become extremely aggressive when provoked, and their bites, if not properly treated, pose a significant risk of infection by microorganisms not usually encountered in cases of animal bites. In this report, we present the case of a patient treated for a fur seal bite during an Antarctic expedition cruise, review the literature concerning seal bites, and suggest the use of antibiotic prophylaxis to prevent complications.

    Throughout the world there are hundreds of historic monuments and structures considered to be invaluable and irreplaceable. They are symbols of cultural identity and a means of educating people about history. Preservation of historic monuments and structures is therefore an important part of safeguarding these cultural heritage sites so that they retain their value for future generations.This report discusses a procedure for the investigation of seismic hazards in existing buildings and possible steps that can be taken to avoid damage caused by these hazards. The Augusta Airship Hangar located in Sicily, will be used as a case study however the topics addressed in this paper can be applied to other structures of historic value around the world.First state-of-the-art scanning procedures were used to create scale digital models that were imported into a structural analysis program. Within this program dynamic analyses were performed on the model based on actual ground motions taken close to the site. This data was used to determine the period and mode shapes of the structure. Then a nonlinear analysis, including a static pushover analysis, was implemented on a two-dimensional model of the structural frame. From this analysis the failure mechanisms of the structure were revealed with relation to an allowable roof displacement. The structural integrity of the structure was evaluated based on pre-defined performance goals. Finally multiple suggestions were made how the Augusta Airship Hangar might be repaired and strengthened so that this structure will not be destroyed should an earthquake occur.The results of our study show that historic structures, despite their age, can still be strong and ductile. Also there are a multitude of effective preservation and retrofit techniques that can be used to strengthen these historic structures, should an earthquake occur. Through this study, the Augusta Airship Hangar has proven to be not only a historic symbol for Sicily but

    Full Text Available The South American Fur Seal Arctocephalus australis is one of the most widely distributed South American otariid species. In Brazil, during austral winter months specimens of A. australis are regularly found along the Rio Grande do Sul and Santa Catarina coasts. Occasionally, vagrants have been recorded along the southeastern coast but rarely moves north of Rio de Janeiro, at 23°S. On 01 May 2015, fishermen noticed in the surf zone an unidentified large animal in Ilhéus, Bahia, northeastern Brazil. Severely wounded, it was still alive when first spotted. Numerous shark bites were observed in the rostrum and flippers, the peduncle was severely lacerated and the intestines were protruding. The specimen was identified as an adult of South American Fur Seal based on the combination of the characteristic coloration of the pelage, head shape, body size, the relatively large eye size, and mainly due to the pronounced three cusped teeth in post canines. Fishermen decided to butcher the carcass and share the meat among their companions. The present record, however, is of special concern as human consumption South American Fur Seal seems to be unusual in Brazil. Pieces of meat were shared among fishermen. In addition, small pieces of blubber were used as bait in the local shark long-line fishery. Consumption of an injured and presumably weak marine mammal carcass points to an increasing risk of contact between potentially harmful viruses, bacteria and fungi and humans. This note represents an alert to public health specialists and wildlife authorities in Brazil. It calls the urgency of an outreach campaign advertising to the potential risks of ingesting bushmeat either from land or aquatic sources. 

  16. A memory like a female Fur Seal: long-lasting recognition of pup's voice by mothers

    Full Text Available In colonial mammals like fur seals, mutual vocal recognition between mothers and their pup is of primary importance for breeding success. Females alternate feeding sea-trips with suckling periods on land, and when coming back from the ocean, they have to vocally find their offspring among numerous similar-looking pups. Young fur seals emit a 'mother-attraction call' that presents individual characteristics. In this paper, we review the perceptual process of pup's call recognition by Subantarctic Fur Seal Arctocephalus tropicalis mothers. To identify their progeny, females rely on the frequency modulation pattern and spectral features of this call. As the acoustic characteristics of a pup's call change throughout the lactation period due to the growing process, mothers have thus to refine their memorization of their pup's voice. Field experiments show that female Fur Seals are able to retain all the successive versions of their pup's call.Em mamíferos coloniais como as focas, o reconhecimento vocal mútuo entre as mães e seu filhote é de importância primordial para o sucesso reprodutivo. As fêmeas alternam viagens de alimentação no mar com períodos de amamentação em terra e, quando voltam à colônia, elas devem achar vocalmente seu filhote no meio de muitos outros visualmente semelhantes. As jovens focas emitem um ''grito de atração da mãe'' que apresenta características individuais. Examinamos aqui o processo perceptual do reconhecimento do grito do filhote pela mãe numa população sub-antártica da foca Arctocephalus tropicalis. Para identificar seu filhote as fêmeas se baseiam no padrão da freqüência de modulação e outras características espectrais deste grito. Como os parâmetros acústicos do grito de um filhote mudam ao longo do período de amamentação por causa do seu crescimento, as mães precisam de uma memorização refinada da voz de seu filhote. Experiências de campo mostram que as fêmeas desta espécie s

    We describe and realize an aligned carbon nanotube array based 'carbon nanotube fur (CNTF)' electrode. We removed an 800 μm long aligned carbon nanotube array from the silica substrate, and then pasted the array on a nickel foam current collector to obtain a CNTF electrode. CNTF's characteristics and electrochemical properties were studied systemically in this paper. The cut-paste method is simple, and does not damage the microstructure of the aligned carbon nanotube array. The CNTF electrode obtained a specific capacitance of 14.1 F g -1 and excellent rate capability

    Human hair and hair from animals might serve as good indicators for internal contamination, allowing for the quantification of general environmental levels of certain radioactive elements. From a sampling, analytical and hygienic point of view it would be advantageous to study hair instead of urine and faeces samples. There have been several investigations concerning Polonium in hair. The purpose of this study was to investigate if hair from humans and fur from animals constitute as matrixes for the estimation of the body burden of 210 Po. Human hair taken from 26 individuals from Sweden was analyzed for its 210 Po content. The resulting activity concentration of 210 Po ranged from 0.5 to 4.8 Bq/kg for individuals between the ages of 3 to 32 years and range from 0.5 to 11.5 Bq/kg for individuals between the ages of 32 to 60. This is in agreement with results presented in other studies. The 210 Po in hair might be due to external contamination or in vivo build up from 210 Pb. To help quantify these sources of contamination a couple of human volunteers ingested known amounts of 209 Po (which does not exist in nature). Results from the study showed that 209 Po was rather rapidly detected in the hair samples Human hair consists of 45% Carbon, 7% Hydrogen, 28% Oxygen, 15% Nitrogen and 5% Sulphur. The central core consists of polypeptide chains with hydrogen and disulphide bindings. It is suggested that the sulphide binding is the reason for transfer of Polonium into the hair. Samples from horses; mane, fur, and tail showed activity concentration levels ranging from 6 to 17 Bq/kg, with no significant differences between the various sample types. Fur samples taken from Muskox from Greenland showed much higher concentrations, i.e. 260 Bq/kg. This was expected since the animal graze over vast surface and consumes large amounts of lichen. Deposited radionuclides accumulate in lichens. Fur samples taken from other animals i.e. moose, hare, wild boar, roe deer, and sheep (lamb

  20. Hindering the illegal trade in dog and cat furs through a DNA-based protocol for species identification

    Full Text Available In Western countries dogs and cats are the most popular pets, and people are increasingly opposed to their rearing for the fur industry. In 2007, a Regulation of the European Union (EU banned the use and trade of dog and cat furs, but an official analytical protocol to identify them as source species was not provided, and violations of law are still frequent in all Member States. In this paper we report on the development and validation of a simple and affordable DNA method for species detection in furs to use as an effective tool to combat illegal trade in fur products. A set of mitochondrial primers was designed for amplification of partial cytochrome b, control region and ND1 gene in highly degraded samples, like furs and pelts. Our amplification workflow involved the use of a non-specific primer pair to perform a first test to identify the species through sequencing, then the application of species-specific primer pairs to use in singleplex end-point PCRs as confirmation tests. The advantage of this two-step procedure is twofold: on the one hand it minimises the possibility of negative test results from degraded samples, since failure of amplification with a first set of primers can be offset by successful amplification of the second, and on the other it adds confidence and reliability to final authentication of species. All designed primers were validated on a reference collection of tissue samples, obtaining solid results in terms of specificity, sensitivity, repeatability and reproducibility. Application of the protocol on real caseworks from seized furs yielded successful results also from old and dyed furs, suggesting that age and chemical staining do not necessarily affect positive amplifications. Major pros of this approach are: (1 sensitive and informative primer sets for detection of species; (2 short PCR amplicons for the analysis of poor quality DNA; (3 binding primers that avoid contamination from human DNA; (4 user

  1. Mother Vocal Recognition in Antarctic Fur Seal Arctocephalus gazella Pups: A Two-Step Process.

    Directory of Open Access Journals (Sweden)

    Thierry Aubin

    Full Text Available In otariids, mother's recognition by pups is essential to their survival since females nurse exclusively their own young and can be very aggressive towards non-kin. Antarctic fur seal, Arctocephalus gazella, come ashore to breed and form dense colonies. During the 4-month lactation period, females alternate foraging trips at sea with suckling period ashore. On each return to the colony, females and pups first use vocalizations to find each other among several hundred conspecifics and olfaction is used as a final check. Such vocal identification has to be highly efficient. In this present study, we investigated the components of the individual vocal signature used by pups to identify their mothers by performing playback experiments on pups with synthetic signals. We thus tested the efficiency of this individual vocal signature by performing propagation tests and by testing pups at different playback distances. Pups use both amplitude and frequency modulations to identify their mother's voice, as well as the energy spectrum. Propagation tests showed that frequency modulations propagated reliably up to 64m, whereas amplitude modulations and spectral content greatly were highly degraded for distances over 8m. Playback on pups at different distances suggested that the individual identification is a two-step process: at long range, pups identified first the frequency modulation pattern of their mother's calls, and other components of the vocal signature at closer range. The individual vocal recognition system developed by Antarctic fur seals is well adapted to face the main constraint of finding kin in a crowd.

    Quantification of the physical and biological environmental factors that influence the spatial distribution of higher trophic species is central to inform management and develop ecosystem models, particularly in light of ocean changes. We used tracking data from 184 female Antarctic fur seals (Arctocephalus gazella) to develop habitat models for three breeding colonies for the poorly studied Southern Ocean winter period. Models were used to identify and predict the broadly important winter foraging habitat and to elucidate the environmental factors influencing these areas. Model predictions closely matched observations and several core areas of foraging habitat were identified for each colony, with notable areas of inter-colony overlap suggesting shared productive foraging grounds. Seals displayed clear choice of foraging habitat, travelling through areas of presumably poorer quality to access habitats that likely offer an energetic advantage in terms of prey intake. The relationships between environmental predictors and foraging habitat varied between colonies, with the principal predictors being wind speed, sea surface temperature, chlorophyll a concentration, bathymetry and distance to the colony. The availability of core foraging areas was not consistent throughout the winter period. The habitat models developed in this study not only reveal the core foraging habitats of Antarctic fur seals from multiple colonies, but can facilitate the hindcasting of historical foraging habitats as well as novel predictions of important habitat for other major colonies currently lacking information of the at-sea distribution of this major Southern Ocean consumer.

    During native subsistence hunts from 1987 to 2007, blubber and liver samples from 50 subadult male northern fur seals (Callorhinus ursinus) were collected on St. Paul Island, Alaska. Samples were analyzed for legacy persistent organic pollutants (POPs), recently phased-out/current-use POPs, and vitamins. The legacy POPs measured from blubber samples included polychlorinated biphenyl congeners, DDT (and its metabolites), chlorobenzenes, chlordanes, and mirex. Recently phased-out/current-use POPs included in the blubber analysis were the flame retardants, polybrominated diphenyl ethers, and hexabromocyclododecanes. The chemical surfactants, perfluorinated alkyl acids, and vitamins A and E were assessed in the liver samples. Overall, concentrations of legacy POPs are similar to levels seen in seal samples from other areas of the North Pacific Ocean and the Bering Sea. Statistically significant correlations were seen between compounds with similar functions (pesticides, flame retardants, vitamins). With sample collection spanning two decades, the temporal trends in the concentrations of POPs and vitamins were assessed. For these animals, the concentrations of the legacy POPs tend to decrease or stay the same with sampling year; however, the concentrations of the current-use POPs increased with sampling year. Vitamin concentrations tended to stay the same across the sampling years. With the population of northern fur seals from St. Paul Island on the decline, a detailed assessment of exposure to contaminants and the correlations with vitamins fills a critical gap for identifying potential population risk factors that might be associated with health effects.

    During wild foraging, Australian fur seals (Arctocephalus pusillus doriferus) encounter many different types of prey in a wide range of scenarios, yet in captive environments they are typically provided with a narrower range of opportunities to display their full repertoire of behaviours. This study aimed to quantitatively explore the effect of foraging-based enrichment on the behaviour and activity patterns displayed by two captive Australian fur seals at Melbourne Zoo, Australia. Food was presented as a scatter in open water, in a free-floating ball device, or in a static box device, with each treatment separated by control trials with no enrichment. Both subjects spent more time interacting with the ball and static box devices than the scatter feed. The total time spent pattern swimming was reduced in the enrichment treatments compared to the controls, while the time spent performing random swimming behaviours increased. There was also a significant increase in the total number of bouts of behaviour performed in all three enrichment treatments compared to controls. Each enrichment method also promoted a different suit of foraging behaviours. Hence, rather than choosing one method, the most effective way to increase the diversity of foraging behaviours, while also increasing variation in general activity patterns, is to provide seals with a wide range of foraging scenarios where food is encountered in different ways.

    The relatively small population size and restricted distribution of the Guadalupe fur seal Arctocephalus townsendi could make it highly vulnerable to infectious diseases. We performed a colony-level assessment in this species of the prevalence and presence of Brucella spp. and Leptospira spp., pathogenic bacteria that have been reported in several pinniped species worldwide. Forty-six serum samples were collected in 2014 from pups at Isla Guadalupe, the only place where the species effectively reproduces. Samples were tested for Brucella using 3 consecutive serological tests, and for Leptospira using the microscopic agglutination test. For each bacterium, a Bayesian approach was used to estimate prevalence to exposure, and an epidemiological model was used to test the null hypothesis that the bacterium was present in the colony. No serum sample tested positive for Brucella, and the statistical analyses concluded that the colony was bacterium-free with a 96.3% confidence level. However, a Brucella surveillance program would be highly recommendable. Twelve samples were positive (titers 1:50) to 1 or more serovars of Leptospira. The prevalence was calculated at 27.1% (95% credible interval: 15.6-40.3%), and the posterior analyses indicated that the colony was not Leptospira-free with a 100% confidence level. Serovars Icterohaemorrhagiae, Canicola, and Bratislava were detected, but only further research can unveil whether they affect the fur seal population.

    The extinct Lithornithidae include several genera and species of flying palaeognathous birds of controversial affinities known from the Early Paleogene of North America and Europe. An almost complete, articulated skeleton from the Early Eocene marine deposits of the Fur Formation (Denmark) was recently assigned to Lithornis vulturinus Owen, 1840. This study provides a detailed redescription and comparison of this three-dimensionally preserved specimen (MGUH 26770), which is one of the best preserved representatives of the Lithornithidae yet known. We suggest that some new features might be diagnostic of Lithornis vulturinus, including a pterygoid fossa shallower than in other species of Lithornis and the presence of a small caudal process on the os palatinum. We propose that Lithornis nasi (Harrison, 1984) is a junior synonym of Lithornis vulturinus and we interpret minor differences in size and shape among the specimens as intraspecific variation. To date, Lithornis vulturinus is known with certainty from the latest Paleocene-earliest Eocene to Early Eocene of the North Sea Basin (Ølst, Fur and London Clay Formations). Among the four species of the genus Lithornis, the possibility that Lithornis plebius Houde, 1988 (Early Eocene of Wyoming) is conspecific with either Lithornis vulturinus or Lithornis promiscuus Houde, 1988 (Early Eocene of Wyoming) is discussed. The presence of closely related species of Lithornis on either side of the North Atlantic in the Early Eocene reflects the existence of a high-latitude land connection between Europe and North America at that time.

    The German Society for Radiation Protection (in German Gesellschaft fur Strahlenschutz) is a separate society for radiation protection in Germany in addition to the leading society named Association of German and Swiss Radiation Protection Specialists (in German Fachverband fur Strahlenschutz). The Society is an international professional society. There are several hundreds members of the German Society for Radiation Protection. The German Society for Radiation Protection is not a member of IRPA (the International Radiation Protection Society). The IRPA member is the Association of German and Swiss Radiation Protection Specialists. According to information given on the web site of the Society for Radiation Protection (www.gfstrahlenschutz.de) the Society was founded in 1990 because in the opinion of the founding members the older professional societies and associations have not adequately considered and implemented the present knowledge of radiation risks and radiation protection. In accordance with its statutes the society pursues besides other aims the best possible protection of humans and the environment from the detrimental action of ionising and non-ionising radiation. The dealing with ionising and non-ionising radiation can according to the Society only be justified on the basis of biological and medical state of the art knowledge

    Stimulation of mystacial vibrissae in rows A,B, and C increased (14C) 2-deoxyglucose (2DG) uptake in spinal trigeminal nucleus pars caudalis (Sp5c) mostly in ventral portions of laminae III-IV with less activation of II and V. Stimulation of common fur above the whiskers mainly activated lamina II, with less activation in deeper layers. The patterns of activation were compatible with an inverted head, onion skin Sp5c somatotopy. Wheatgerm Agglutinin-Horseradish Peroxidase (WGA-HRP) injections into common fur between mystacial vibrissae rows A-B and B-C led to anterograde transganglionic labeling only of Sp5c, mainly of lamina II with less label in layer V, and very sparse label in III and IV. WGA-HRP skin injections appear to primarily label small fibers, which along with larger fibers, were metabolically activated during common fur stimulation. Mystacial vibrissae stimulation increased 2DG uptake in ventral ipsilateral spinal trigeminal nuclei pars interpolaris (Sp5i) and oralis (Sp5o) and principal trigeminal sensory nucleus (Pr5). Common fur stimulation above the whiskers slightly increased 2DG uptake in ventral Sp5i, Sp5o, and possibly Pr5. The most dorsal aspect of the ventroposteromedial (VPM) nucleus of thalamus was activated contralateral to whisker stimulation. Stimulation of the common fur dorsal to the whiskers activated a region of dorsal VPM caudal to the VPM region activated during whisker stimulation. This is consistent with previous data showing that ventral whiskers and portions of the face are represented rostrally in VPM, and more dorsal whiskers and dorsal portions of the face are represented progressively more caudally in VPM. Mystacial vibrissae stimulation activated the contralateral primary sensory SI barrelfield cortex and a separate region in the second somatosensory SII cortex

    Previous genomic analyses of the filamentous nitrogen-fixing cyanobacterium Anabaena sp. PCC 7120 have identified three ferric uptake regulator (Fur) homologs with low sequence identities and probably different functions in the cell. FurA is a constitutive protein that shares the highest homology with Fur from heterotrophic bacteria and appears to be essential for in vitro growth. In this study, we have analysed the effects of FurA overexpression on the Anabaena sp. phenotype and investigated which of the observed alterations were directly operated by FurA. Overexpression of the regulator led to changes in cellular morphology, resulting in shorter filaments with rounded cells of different sizes. The furA-overexpressing strain showed a slower photoautotrophic growth and a marked decrease in the oxygen evolution rate. Overexpression of the regulator also decreased both catalase and superoxide dismutase activities, but did not lead to an increase in the levels of intracellular reactive oxygen species. By combining phenotypic studies, reverse transcription-PCR analyses and electrophoretic mobility shift assays, we identified three novel direct targets of FurA, including genes encoding a siderophore outer membrane transporter (schT), bacterial actins (mreBCD) and the PSII reaction center protein D1 (psbA). The affinity of FurA for these novel targets was markedly affected by the absence of divalent metal ions, confirming previous evidence of a critical role for the metal co-repressor in the function of the regulator in vivo. The results unravel new cellular processes modulated by FurA, supporting its role as a global transcriptional regulator in Anabaena sp. PCC 7120.

    Persistent wheeze in childhood is associated with airway inflammation. The present study investigated relationships between polymorphisms in inflammatory genes, exposure to tobacco smoke and furred pets and risk of recurrent wheeze in children. Within a birth cohort of 101,042 children we...... identified 1111 eighteen month old cases with recurrent wheeze and 735 wheeze-free controls among 11942 children recruited in the Copenhagen area. Polymorphisms in IL-4R, IL-8, IL-13, SPINK5, and CD14 were genotyped. Interviews at gestational wks 12 and 30, and at age 6 and 18 months included questions...... on number of episodes with wheeze (18 months), exposure to tobacco smoke and pet-keeping. Recurrent wheeze was defined as at least four episodes of wheeze before the child was 18 months old. There was a statistically significant association between the IL-13 Arg144Gln polymorphism and risk of recurrent...

    Chemical communication underpins virtually all aspects of vertebrate social life, yet remains poorly understood because of its highly complex mechanistic basis. We therefore used chemical fingerprinting of skin swabs and genetic analysis to explore the chemical cues that may underlie mother–offspring recognition in colonially breeding Antarctic fur seals. By sampling mother–offspring pairs from two different colonies, using a variety of statistical approaches and genotyping a large panel of microsatellite loci, we show that colony membership, mother–offspring similarity, heterozygosity, and genetic relatedness are all chemically encoded. Moreover, chemical similarity between mothers and offspring reflects a combination of genetic and environmental influences, the former partly encoded by substances resembling known pheromones. Our findings reveal the diversity of information contained within chemical fingerprints and have implications for understanding mother–offspring communication, kin recognition, and mate choice.

    The tail gland of the red fox (Vulpes vulpes) secretes lipids containing volatile terpenes used in social communication. We have analysed lipids extracted from fur of the tail gland, body (flanks) and muzzle of foxes. GC-MS showed a novel group of iso-valerate and tiglate monoesters of alkane-1,2-diols (C18:0-22:0). There was also a larger group of Type II diesters in which a second, longer chain, fatty acid (FA) was attached to the free alcohol group. LC-MS showed the full range of diol diesters, mostly C36:0-50:0, with smaller amounts of the corresponding mono-unsaturated tiglate esters. An additional group of diesters with higher MW (C49:0-62:0) containing two long-chain FA was present in the lipids of body and muzzle fur. After saponification and GC-MS, 98 fatty acids were characterized as their methyl esters. Apart from the C5 FA, most were saturated n-, iso-, anteiso- or other methyl-branched FA (C12:0-28:0) whose structures were determined by a combination of their mass spectra and Kovats retention indices. Several FA have not previously been found in nature or in vertebrates. Thirty-four alkane-1,2-diols were found as their TMS derivatives, mostly n-, iso- or anteiso-isomers of C16:0-25:0. The tail gland had the greatest amount of wax esters, from a greater variety of FA and diols, but lacked the esters with two long-chain FA. These findings show that fox skin lipids comprise mono- and di-esters of alkane-1,2-diols, and exhibit enormous complexity due to the diversity of their constituent FA, diols and the many possible isomers of their esters.

    The objective of the study was to systematically review the efficacy and safety of flexible ureterorenoscopy (F-URS) with holmium laser versus extracorporeal shock wave lithotripsy (ESWL) for the treatment of renal stone ESWL (WMD = 2.13, 95 % CI 1.13-4.00, P = 0.02). F-URS is associated with higher SFR, lower APR and RR than ESWL. F-URS is a safe and effective procedure. It can successfully treat patients with stones for 1-2 cm, especially for lower pole stone, without increasing complications, operative time and hospital stay. F-URS can be used as an alternative treatment to ESWL in selected cases with larger renal stones. However, further randomized trials are needed to confirm these findings.

    What factors allow some species to survive in the face of climate change, disease, or anthropogenic disturbance? How do species shift their geographic distributions in the face of such challenges? These pressing questions in ecology and conservation biology are difficult to answer when looking solely at modern populations or the recent historical record. We explore these questions through analysis of DNA and the isotopic composition of modern and ancient northern fur seals (NFS, Callorhinus ursinus). The NFS is an eared seal (otariid) that ranges along the north Pacific, where it breeds on offshore islands; by far the largest modern rookeries are on the Pribilof Islands in the Bering Sea. The species shows a high degree of philopatry, and females feed while nursing, wean pups at 4 months, and spend the rest of the year foraging far offshore further south. Archaelogical study reveals that Holocene NFS had numerous breeding colonies from the Channel Islands to the Aleutians. Temperate latitude colonies collapsed in the late Holocene in response to hunting pressures and perhaps, environmental change. The species has recolonized parts of its former range since the 1960s. Despite facing similar threats, other marine mammals have failed to rebound (e.g., Guadalupe fur seals) or have exceptionally low genetic diversity indicating recent and prolonged bottlenecks (e.g., northern elephant seals). Isotopic analyses of sub-fossil growth series indicate that extirpated mid-latitude colonies weaned much later (≥12 months), like all other otariid species that breed at temperate latitudes. As a result, females were tied to rookery sites year-round and had a much-reduced migratory range relative to modern NFS females breeding in the Bering Sea, a result also supported by isotopic analyses. Serial coalescent simulations of ancient and modern DNA reveals that exceptionally high migration rates and Arctic refugia provided resilience to NFS. These traits allowed the species to

    Full Text Available Technical advances in monitoring devices, specifically drones, are allowing managers and scientists to obtain quality information on ecosystem health with minimal disturbance to ecosystems and the wildlife they support. Temporal and spatial indicators of ecosystem health, such as population size and/or abundance estimates of marine mammals are the basis for our understanding and prediction of ecosystem change. This is critical for the achievement of conservation goals and sustainable natural resources use. Performing surveys to obtain abundance estimates can be logistically demanding and expensive particularly in offshore marine environments, and can cause significant disturbance to wildlife. These constraints may lead to sub-optimal monitoring programs that reduce the frequency and/or precision of surveys at the cost of data quality and confidence in the resulting analyses. Using Remote Piloted Aircraft (RPA can be a solution to this challenge. With appropriate testing and ethical consideration; for many situations, RPAs can perform surveys with increased frequency, higher data resolution and less disturbance than typical methods that involve people being present on the ground, thereby enabling more robust programs for monitoring. We demonstrate the process of testing images from RPAs for estimating the abundance of Australian fur seals (Arctocephalus pusillus doriferus at one of their largest colonies on Seal Rocks, Australia. Two sizes of multirotor (1,400 and 350 mm with different imaging equipment were tested at 40, 60, and 80 m altitude above sea level. We assessed wildlife disturbance levels and optimized a methodology for effective and economical monitoring of this site. We employed commercially available and open-source software for programming survey flights (Drone Deploy, image processing (Agisoft Photoscan and Autopano Giga, data collation and analyses (R and Python.

    Full Text Available ABSTRACT: This study evaluated the concentration of Der p 1, Der f 1 and Blo t 5 in the fur and households of 20 dogs with atopic dermatitis (AD and 20 healthy dogs. The diagnosis of AD was clinical based on Favrot’s criteria. Dust samples were collected with a domestic vacuum cleaner. For each site, 1m2 was vacuumed for 2 min. The samples were collected in separate filters, transferred into plastic containers, sealed and kept frozen until ELISA analysis. In the fur of atopic dogs the average concentration of Der p 1 was 0.25μg/g compared to 0.03μg/g in healthy dogs. In households with atopic dogs the highest concentrations of Der p 1 were found in carpets (2.18μg/g, followed by couches (1.53μg/g, beds (1.14μg/g, dogs’ bed linen (0.64μg/g and floors (0.14μg/g. The concentrations of Der p 1 on carpets, couches and beds were significantly higher than in atopic dogs’ fur (p0.05. The concentrations of Der p 1, Der f 1 and Blo t 5 were equivalent in atopic and non-atopic dog’s households. Among the allergens studied, Der p 1 was the most commonly found, predominantly in carpets and couches.

L., Tolliver, S. C., Spraker, T. R. — Review of main studies on biology and ecology of the hookworm Uncinaria lucasi Stiles, 1901 performed on St. Paul Island, Alaska, is presented. Current data on prevalence of adult hookworms parasitizing northern fur seals (NFS, Callorhinus ursinus Linnaeus, 1758, were obtained based on the examination of the intestines of dead NFS pups and subadult 3-4 year-old males in July and August of 2011-2013. In addition, blubber samples collected from subadult NFS males were examined for parasitic third stage hookworm larvae (L3. All current data were compared with previously published studies performed in 1950s-1960s. Current prevalence of U. lucasi in dead pups collected from Reef Rookery was 4.9 % in 2011, 0 % in 2012 and 10.5 % in 2013. This rookery has a rocky substrate. On sandy rookeries prevalence was up to 75 % on Morjovi Rookery and 50 % on Vostochni Rookery. Parasitic L3 were recovered in 2.5 % of subadult males examined in 2013. Decreasing prevalence of hookworm infection of dead pups and subadult males during the last several years follows the tremendous decline in the number of fur seals in the herd on St. Paul Island during last several decades.

    Full Text Available Microorganisms that reside on and in mammals, such as bats, have the potential to influence their host’s health and to provide defenses against invading pathogens. However, we have little understanding of the skin and fur bacterial microbiota on bats, or factors that influence the structure of these communities. The southwestern United States offers excellent sites for the study of external bat bacterial microbiota due to the diversity of bat species, the variety of abiotic and biotic factors that may govern bat bacterial microbiota communities, and the lack of the newly emergent fungal disease in bats, white-nose syndrome (WNS, in the southwest. To test these variables, we used 16S rRNA gene 454 pyrosequencing from swabs of external skin and fur surfaces from 163 bats from 13 species sampled from southeastern New Mexico to northwestern Arizona. Community similarity patterns, random forest models, and generalized linear mixed-effects models show that factors such as location (e.g., cave-caught versus surface-netted and ecoregion are major contributors to the structure of bacterial communities on bats. Bats caught in caves had a distinct microbial community compared to those that were netted on the surface. Our results provide a first insight into the distribution of skin and fur bat bacteria in the WNS-free environment of New Mexico and Arizona. More importantly, it provides a baseline of bat external microbiota that can be explored for potential natural defenses against pathogens.

    No significant differences were observed in the net birth rate of mink kits/female between the 7 breeding groups. However, there was reduced incidence (P=0.05) of kit deaths among the females receiving irradiated feed, and larger kit size (P<0.0001) at birth particularly for the litter size of 5-8 kits. The second generation minks born to parents receiving feed irradiated to a planned dose of 1 kGy weighed on average about 2.5% more, and their fur was on average about 1{plus minus}0.26 cm longer (12% more males making the top length grade). Moreover, there was no effect of irradiated feed on fur quality. Irradiation of mink feed with subsequent frozen storage of the meat component improved the microbiological quality by decreasing the incidence of Pseudomonas sp. and Salmonella sp. Radiation pasteurization of mink feed (frozen meat to 1 kGy, and dry feed to 2 kGy or more) should therefore help improve feed utilization, keep animals healthier, and reproducing better without affecting fur quality.

    Chirodiscoides caviae is the most common fur mite affecting guinea pigs; infestation is generally asymptomatic. No studies have been published on the prevalence of such mites in guinea pigs in southern Italy. We sought to evaluate the prevalence and the clinical signs of C. caviae infestation in guinea pigs in southern Italy. Clinical records of guinea pigs evaluated from August 2012 to July 2013 were retrospectively searched. In this retrospective matched case-control study, records of guinea pigs with evidence of C. caviae infestation were selected. The prevalence of C. caviae infestation was evaluated and exposure variables were assessed among guinea pigs with and without infestation using stepwise conditional logistic regression. Guinea pigs seen during the same time period, but without a diagnosis of C. caviae, were included as control animals. The prevalence of C. caviae was 32% (42 of 131); 66.6% of affected guinea pigs (28 of 42) originated from pet shops, whereas 28% (14 of 42) were privately owned. Thirty-one guinea pigs (73.8%) were asymptomatic, whereas 11 (26.1%) showed clinical signs (pruritus, alopecia, erythema and scaling). The most frequently affected area was the lumbosacral region (38 of 42). Guinea pigs in pet shops were more likely to be affected by C. caviae than owned guinea pigs (odds ratio, 5.12; 95% confidence interval, 2.32-11.29; P guinea pigs in southern Italy.

    Brucella species infect a wide range of hosts with a broad spectrum of clinical manifestations. In mammals, one of the most significant consequences of Brucella infection is reproductive failure. There is evidence of Brucella exposure in many species of marine mammals, but the outcome of infection is often challenging to determine. The eastern Pacific stock of northern fur seals (NFSs, Callorhinus ursinus) has declined significantly, spawning research into potential causes for this trend, including investigation into reproductive health. The objective of the current study was to determine if NFSs on St. Paul Island, Alaska have evidence of Brucella exposure or infection. Archived DNA extracted from placentas ( n = 119) and serum ( n = 40) samples were available for testing by insertion sequence (IS) 711 polymerase chain reaction (PCR) and the Brucella microagglutination test (BMAT), respectively. As well, placental tissue was available for histologic examination. Six (5%) placentas were positive by PCR, and a single animal had severe placentitis. Multilocus variable number tandem repeat analysis profiles were highly clustered and closely related to other Brucella pinnipedialis isolates. A single animal was positive on BMAT, and 12 animals had titers within the borderline range; 1 borderline animal was positive by PCR on serum. The findings suggest that NFSs on the Pribilof Islands are exposed to Brucella and that the organism has the ability to cause severe placental disease. Given the population trend of the NFS, and the zoonotic nature of this pathogen, further investigation into the epidemiology of this disease is recommended.

    An increased number of tourists viewing animals in the wild have increased stress on these animals (hereafter wildlife). Many wildlife-viewing locations rely on voluntary compliance with posted regulations to protect animals from tourists because of the expense of employing on-site enforcement personnel. Voluntary compliance, however, is ineffective. The presence of official-looking volunteers may decrease the incidence of wildlife harassment by tourists. To test this possibility, we observed tourists interacting with 5- to 12-month-old New Zealand fur seals (Arctocephalus forsteri) at the popular Ohau Stream waterfall while in the absence or presence of a young woman in plain sight wearing a neon vest (i.e., observer) and when an observer was not present. We observed 254 tourist groups at the waterfall when young seals were present. The percentage of groups in which at least one person harassed (approached, touched, or threw objects) a young seal was two-thirds lower when the official-looking observer was present. Frequency of harassment was inversely related to observer presence. Programs in which volunteers work at tourist sites are popular in countries with high tourism rates, such as New Zealand. Our results show that a relatively inexpensive and effective tourism-management strategy may be to post such volunteers as observers at sites where tourists view wildlife. ©2010 Society for Conservation Biology.

Seven percent of 133 SAFS analyzed presented marine debris in their stomach (n=10), with no differences between sampling countries (Brazil n=7, Argentina n=3) and sexes (female=3; male=6). However, significant differences were observed between ages classes, with MD exclusively present in stomach contents of young specimens. Plastics represents 90% of MD ingested by the SAFS, whereas regarding the source, fishery-related items (e.g. monofilament lines) were the main MD (70%), with a lesser proportion of packaging (e.g. pieces of bags). Low numbers but large size pieces of MD were found in each stomach affected. Negative effects on the individuals could not be fully evaluated. Therefore, the potential impacts of the marine debris to the SAFS deserve further elucidation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The purpose of this study was to determine whether analysis of the elemental content of fur from San Joaquin kit foxes (Vulpes macrotis mutica) and of water and soil from kit fox habitats could be used to make inferences concerning the cause of an observed decline in the kit fox population on Naval Petroleum Reserve No. 1 (NPR-1). Fur samples that had been collected previously from NPR-1, another oil field (NPR-2), and two sites with no oil development were subjected to neutron activation analysis. In addition, soil samples were collected from the home ranges of individual foxes from undisturbed portions of major soil types on NPR-1 and from wastewater samples were collected from tanks and sumps and subjected to neutron activation analysis. Most elemental concentrations in fur were highest at Camp Roberts and lowest on the undeveloped portions of NPR-I. Fur concentrations were intermediate on the developed oil fields but were correlated with percent disturbance and with number of wells on NPR-1 and NPR-2. The fact that most elements covaried across the range of sites suggests that some pervasive source such as soil was responsible. However, fur concentrations were not correlated with soft concentrations. The kit foxes on the developed portion of NPR-1 did not have concentrations of elements in fur relative to other sites that would account for the population decline in the early 1980s. The oil-related elements As, Ba, and V were elevated in fox fur from oil fields, but only As was sufficiently elevated to suggest a risk of toxicity in individual foxes. However, arsenic concentrations suggestive of sublethal toxicity were found in only 0.56% of foxes from developed oil fields, too few to account for a population decline.

    Population declines resulting from anthropogenic activities are of major consequence for the long-term survival of species because the resulting loss of genetic diversity can lead to extinction via the effects of inbreeding depression, fixation of deleterious mutations, and loss of adaptive potential. Otariid pinnipeds have been exploited commercially to near extinction with some species showing higher demographic resilience and recolonization potential than others. The New Zealand fur seal (NZFS) was heavily impacted by commercial sealing between the late 18th and early 19th centuries, but has recolonized its former range in southern Australia. The species has also recolonized its former range in New Zealand, yet little is known about the pattern of recolonization. Here, we first used 11 microsatellite markers (n = 383) to investigate the contemporary population structure and dispersal patterns in the NZFS (Arctocephalus forsteri). Secondly, we model postsealing recolonization with 1 additional mtDNA cytochrome b (n = 261) marker. Our data identified 3 genetic clusters: an Australian, a subantarctic, and a New Zealand one, with a weak and probably transient subdivision within the latter cluster. Demographic history scenarios supported a recolonization of the New Zealand coastline from remote west coast colonies, which is consistent with contemporary gene flow and with the species' high resilience. The present data suggest the management of distinct genetic units in the North and South of New Zealand along a genetic gradient. Assignment of individuals to their colony of origin was limited (32%) with the present data indicating the current microsatellite markers are unlikely sufficient to assign fisheries bycatch of NZFSs to colonies. © The American Genetic Association 2016.

  16. Temporal allocation of foraging effort in female Australian fur seals (Arctocephalus pusillus doriferus.

    Directory of Open Access Journals (Sweden)

    Andrew J Hoskins

    Full Text Available Across an individual's life, foraging decisions will be affected by multiple intrinsic and extrinsic drivers that act at differing timescales. This study aimed to assess how female Australian fur seals allocated foraging effort and the behavioural changes used to achieve this at three temporal scales: within a day, across a foraging trip and across the final six months of the lactation period. Foraging effort peaked during daylight hours (57% of time diving with lulls in activity just prior to and after daylight. Dive duration reduced across the day (196 s to 168 s but this was compensated for by an increase in the vertical travel rate (1500-1600 m·h(-1 and a reduction in postdive duration (111-90 s. This suggests physiological constraints (digestive costs or prey availability may be limiting mean dive durations as a day progresses. During short trips (2.9 d effort increased up to 2-3 d and then decreased. Dive duration decreased at the same rate in short and long trips, respectively, before stabilising (long trips between 4-5 d. Suggesting that the same processes (digestive costs or prey availability working at the daily scale may also be present across a trip. Across the lactation period, foraging effort, dive duration and vertical travel rate increased until August, before beginning to decrease. This suggests that as the nutritional demands of the suckling pup and developing foetus increase, female effort increases to accommodate this, providing insight into the potential constraints of maternal investment in this species.

    We analyzed long-term dietary records of northern fur seals (Callorhinus ursinus) to reconstruct historical changes in prey availability and diversity in the western North Pacific off northeastern Japan. The nominal relationships between the occurrence frequencies of fishes or squids in fur seal stomachs and the sampling locations reflected the spatial heterogeneity of fish and squid distributions along the shelf-slope-offshore continuum off northeastern Japan, whereas changes in the temporal occurrence frequencies reflected mainly the migration and foraging patterns of the fur seals. The occurrence probabilities of fishes and squids in fur seal stomachs were standardized by using generalized linear models to compensate for sampling biases in space and time. The reconstructed historical trends revealed decadal shifts in relatively high prey abundance-from mackerels in the 1970s to Japanese sardine in the 1980s and myctophids/sparkling enope squids in the 1990s-that were related to decadal shifts in the oceanographic regime. The sequential increase in mackerel and Japanese sardine abundances coincided with the annual catch trends of commercial fisheries. The index of overall prey availability calculated from the standardized occurrence probabilities of fishes and squids in fur seal stomachs was fairly stable over the decades.

    Full Text Available The work aimed at the analysis of the factors that influence conformation traits, included animal size and fur quality traits in four colour types of mink: standard, pastel, platinum and white Hedlunda. The data concerns the evaluation of animal conformation traits in the period of three years. The analysis of variance of particular traits indicates statistically significant effect of the year of birth, colour type and animal sex on the majority of analysed traits. Higher means of license evaluation were obtained by males in majority of the traits. Statistic analysis of body weight showed that the highest body weight characterized males of platinum and white Hedlunda colour types. Minks of standard and pastel colour types were characterised by lower body weight. The mean body weight of males was 2581.17g and of females 1401.42g (there is a clear sexual dimorphism in minks. Minks of white Hedlunda colour type were characterised by the highest means of colour purity, both males and females. Other colour types obtained lower means. The best fur quality characterised platinum minks. Variability of traits, measured by variability coefficient, had the highest values in animal weight (in grams and ranged from 6.0 to 32.0%. Variability of total number of scores ranged from 2.00 to 8.20%. Positive phenotypic correlations were the highest between body size (in points and total number of scores (0.676, while the lowest were obtained between body size (in points and fur quality (–0.178.

  19. Do black-furred animals compensate for high solar absorption with smaller hairs? A test with a polymorphic squirrel species

    2011-12-01

    Full Text Available In polymorphic mammalian species that display multiple color forms, those with dark, or melanic pelage would be prone to overheating, especially if they live in warm climates, because their fur absorbs solar energy at a higher rate. However, experimental studies indicate that certain physical properties of fur of dark individuals appear to prevent, or minimize heat stress, although it is not clear what properties do so. Here, we tested the possibility that black-furred individuals simply have shorter or thinner hair fibers, which would create a lighter (in terms of weight coat or one that allows greater air flow for evaporative coo- ling. We examined museum specimens of eastern fox squirrels Sciurus niger, a species native to the United States and one that displays brown, grey or all-black pelage color, and used image analysis procedures to quantify hairs from the dorsal surface and tail. From examination of 43 specimens (19 brown, 9 black and 15 grey, and 1,720 hairs, we found no significant difference in hair lengths across color morphs, but significant differences in hair fiber widths. Black squirrels had thinner body hairs than other forms (7% thinner, but thicker tail hairs (9% thicker than the others. Given that the dorsal surface would be directly exposed to solar radiation, we interpret this to be an adaptation to prevent heat stress during the day. The thicker tail hairs may be an adaptation for nighttime thermoregulation, since squirrels sleep with their tails wrapped around their bodies. These results add to a growing literature body of the functional significance of mammalian pelage [Current Zoology 57 (6: 731–736, 2011].

    We report on the intestinal helminth fauna of 56 South American sea lions, Otaria flavescens, and 5 South American fur seals, Arctocephalus australis, from northern Patagonia, Argentina. A total of 97,325 helminth specimens were collected from sea lions. Gravid individuals were represented by 6 species of parasites: 1 digenean (Ascocotyle (Ascocotyle) patagoniensis), 1 cestode (Diphyllobothrium spp.), 3 nematodes (Uncinaria hamiltoni, Contracaecum ogmorhini s.s., Pseudoterranova cattani) and 1 acanthocephalan (Corynosoma australe). In addition, third-stage larvae of 2 nematodes (Contracaecum sp. and Anisakis sp. type I) and 3 juvenile acanthocephalans (Andracantha sp., Profilicollis chasmagnathi and Corynosoma cetaceum) were also collected. Andracantha sp., C. ogmorhini s.s. and P. chasmagnathi represent new host records. A total of 1516 helminth specimens were collected from fur seals. Gravid individuals were represented by three species of parasites, namely, Diphyllobothrium spp., C. ogmorhini s.s. and C. australe. In addition, larvae of Contracaecum sp. and P. cattani, juveniles of C. cetaceum and immature cestodes (Tetrabothriidae gen. sp.) were also collected. Corynosoma australe was the most prevalent and abundant parasite in both hosts, accounting for >90% of all specimens. Sea lions and furs seals from northern Patagonia harbour the intestinal helminth communities that could be predicted for otariids, i.e. the combination of species of the genera Corynosoma, Diphyllobothrium, Pseudoterranova, Contracaecum and, in pups, Uncinaria. Additionally, both species of otariid are apparently unsuitable hosts (i.e. non-hosts) for as many as five parasite taxa. The inclusion or exclusion of these species affects estimation of species richness at both component community (11 versus 6 species in sea lions; 7 versus 3 species in fur seals) and infracommunity (mean: 3.1 versus 2.6 in sea lions; 2.2 versus 1.7 species) levels.

    An experimental investigation has been conducted to determine the dynamic stability and control characteristics of a 0.13-scale free-flight model of the Convair XFY-1 airplane in test setups representing the setup proposed for use in the first flight tests of the full-scale airplane in the Moffett Field airship hangar. The investigation was conducted in two parts: first, tests with the model flying freely in an enclosure simulating the hangar, and second, tests with the model partially restrained by an overhead line attached to the propeller spinner and ground lines attached to the wing and tail tips. The results of the tests indicated that the airplane can be flown without difficulty in the Moffett Field airship hangar if it does not approach too close to the hangar walls. If it does approach too close to the walls, the recirculation of the propeller slipstream might cause sudden trim changes which would make smooth flight difficult for the pilot to accomplish. It appeared that the tethering system proposed by Convair could provide generally satisfactory restraint of large-amplitude motions caused by control failure or pilot error without interfering with normal flying or causing any serious instability or violent jerking motions as the tethering lines restrained the model.

    Mice that carry the lethal yellow (A{sup y}) or viable yellow (A{sup vy}) mutation, two dominant mutations of the agouti (a) gene in mouse chromosome 2, exhibit a phenotype that includes yellow fur, marked obesity, a form of type II diabetes associated with insulin resistance, and an increased susceptibility to tumor development. Molecular analyses of these and several other dominant {open_quotes}obese yellow{close_quotes} a-locus mutations suggested that ectopic expression of the normal agouti protein gives rise to this complex pleiotropic phenotype. We have now tested this hypothesis directly by generating transgenic mice that ectopically express an agouti cDNA clone encoding the normal agouti protein in all tissues examined. Transgenic mice of both sexes have yellow fur, become obese, and develop hyperinsulinemia. In addition, male transgenic mice develop hyperglycemia by 12-20 weeks of age. These results demonstrate conclusively that the ectopic agouti expression is responsible for most, if not all, of the phenotypic traits of the dominant, obese yellow mutants. 42 refs., 5 figs.

    During five reproductive seasons, we documented the presence, extent and origin of perineal wounds in South American fur seal pups ( Arctocephalus australis ) on Guafo Island, Northern Chilean Patagonia. The seasonal prevalence of perineal wounds ranged from 5 to 9%, and new cases were more common at the end of the breeding season (February), when pups were on average two months old and were actively expelling hookworms ( Uncinaria sp). Histologically, wounds corresponded to marked ulcerative lymphoplasmacytic and histiocytic dermatitis with granulation tissue and mixed bacterial colonies. In 2015 and 2017, kelp gulls ( Larus dominicanus ) and dolphin gulls ( Leucophaeus scoresbii ) were observed picking and wounding the perineal area of marked pups. This behaviour occurred more frequently after the pups' defecation, when sea gulls engaged in consumption of pups' faeces. The affected pups usually had moderate to marked hookworm infections along with bloody diarrhoea and anaemia. Pups with severe wounds (23% of affected animals) had swollen perineal areas and signs of secondary systemic bacterial infection. We propose that seagulls on Guafo Island have learned to consume remains of blood and parasites in the faeces of pups affected by hookworm infection, causing perineal wounds during this process. We conclude that this perineal wounding is an unintentional, occasional negative effect of an otherwise commensal gull-fur seal relationship.

    Observations of colliding galaxy clusters with high relative velocity probe the tail of the halo pairwise velocity distribution with the potential of providing a powerful test of cosmology. As an example it has been argued that the discovery of the Bullet Cluster challenges standard Λ cold dark matter (ΛCDM) model predictions. Halo catalogues from N-body simulations have been used to estimate the probability of Bullet-like clusters. However, due to simulation volume effects previous studies had to rely on a Gaussian extrapolation of the pairwise velocity distribution to high velocities. Here, we perform a detail analysis using the halo catalogues from the Dark Energy Universe Simulation Full Universe Runs (DEUS-FUR), which enables us to resolve the high-velocity tail of the distribution and study its dependence on the halo mass definition, redshift and cosmology. Building upon these results, we estimate the probability of Bullet-like systems in the framework of Extreme Value Statistics. We show that the tail of extreme pairwise velocities significantly deviates from that of a Gaussian, moreover it carries an imprint of the underlying cosmology. We find the Bullet Cluster probability to be two orders of magnitude larger than previous estimates, thus easing the tension with the ΛCDM model. Finally, the comparison of the inferred probabilities for the different DEUS-FUR cosmologies suggests that observations of extreme interacting clusters can provide constraints on dark energy models complementary to standard cosmological tests.

    This document illustrates guidelines for the efficient installation of interior duct systems in new housing, including the fur-up chase method, the fur-down chase method, and interior ducts positioned in sealed attics or sealed crawl spaces. This document illustrates guidelines for the efficient installation of interior duct systems in new housing. Interior ducts result from bringing the duct work inside a home's thermal and air barrier. Architects, designers, builders, and new home buyers should thoroughly investigate any opportunity for energy savings that is as easy to implement during construction, such as the opportunity to construct interior duct work. In addition to enhanced energy efficiency, interior ductwork results in other important advantages, such as improved indoor air quality, increased system durability and increased homeowner comfort. While the advantages of well-designed and constructed interior duct systems are recognized, the implementation of this approach has not gained a significant market acceptance. This guideline describes a variety of methods to create interior ducts including the fur-up chase method, the fur-down chase method, and interior ducts positioned in sealed attics or sealed crawl spaces. As communication of the intent of an interior duct system, and collaboration on its construction are paramount to success, this guideline details the critical design, planning, construction, inspection, and verification steps that must be taken. Involved in this process are individuals from the design team; sales/marketing team; and mechanical, insulation, plumbing, electrical, framing, drywall and solar contractors.

    The Palaeocene-Eocene Thermal Maximum (PETM) at ~56 Ma is one of the most extreme global warming events in Earth's history. Vast quantities of CO2 and CH4 were released to the atmosphere, causing a rapid (within 20,000 years) 5-6 °C warming that persisted for ~170,000 years. The PETM occurred during an abnormally warm period in Earth history, and was followed by other hyperthermal events later in the Eocene. The PETM also coincided with the second and major pulse of magmatism from the North Atlantic Igneous Province (NAIP) during the break-up of Laurentia and Eurasia at 54-56 Ma. Evidence of explosive volcanism is prevalent at Fur, an island in northern Denmark, where over 180 distinct >1 cm thick ash horizons are preserved in a shallow marine succession (numbered from #-39 to #+140). These ash layers are believed to have originated from volcanic centres in east Greenland and western UK, which indicates that that they were formed during very large volcanic eruptions. Here we present the results of two key sections of the Fur Formation: a beach section at Stolleklint that includes sediment deposited syn-PETM, and a quarry section at Jenshøj that encompasses post-PETM sediments. A detailed chemostratigraphic log of δ13C (TOC) and δ15N values through the section suggests that there may be part of sequence missing, either through glaciotectonism or a depositional hiatus. The δ13C values around ash #-33 are typical of the PETM negative carbon isotope excursion (-31 to -32 ‰), yet are back to background values of ~-26 ‰ just four metres up section. The quarry section around ash #+19 displays further variations in δ13C values, suggesting a coincidence with one of the later Eocene hyperthermal events. High precision U-Pb dating of magmatic zircons from ash layer #+19 conforms to a post-PETM depositional age, giving a mean deposition rate of approximately ~5 cm kyr-1. The correlation between the largest ash layers (#-33 and #+19) and the largest perturbations to

    the optimal management of lower calyceal stones is still controversial, because no single method is suitable for the removal of all lower calyceal stones. Minimally invasive procedures such as extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL) and flexible ureteroscopy (fURS) are the therapeutic methods for lower calyceal stones. The aim of this study was to identify the optimal management of 10-20 mm lower pole stones. a meta-analysis of cohort studies published before July 2016 was performed from Medline and Cochrane databases. Management of 10-20 mm lower pole stone treated by fURS, ESWL and PCNL with follow-up of residual stones in 1-3 months after procedure were include and urinary stone in other location and size were excluded. A fixed-effects model with Mantzel-Haenzel method was used to calculate the pooled Risk Ratio (RRs) and 95% Confidence Interval (CIs). We assessed the heterogeneity by calculating the I2 statistic. All analyses were performed with Review manager 5.3. we analized 8 cohort studies. The stone free rate from 958 patients (271 PCNL, 174 fURS and 513 ESWL), 3 months after operation, was 90.8% (246/271) after PCNL; 75.3% (131/174) after fURS; and 64.7% (332/513) after ESWL. Base on stone free rate in 10-20 mm lower pole stone following management, PCNL is better than fURS (overall RR was 1.32 (95% CI 1.13 - 1.55); pESWL (overall risk ratio 1.42 (95% CI 1.30 - 1.55); p=ESWL, fURS is better than ESWL base on stone free rate in 10-20 mm lower pole stone management with overall RR 1.16 (95% CI 1.04 - 1.30; p=0.01 and I2=40%). percutaneus nephrolithotomy provided a higher stone free rate than fURS and ESWL. This meta-analysis may help urologist in making decision of intervention in 10-20 mm lower pole stone management.

    Two novel prenylated kaempferol derivatives (1, 2), together with seven known metabolites were isolated from ethanol extract of fresh Platanus acerifolia bud's fur by multistep chromatographic processing. Structure of compounds 1 and 2 was confirmed by 1D, 2D NMR spectra and HR-ESI-MS. In addition, compound 1 was further analysed by X-ray crystallography. Anti-proliferative activities in vitro against human breast carcinoma (MCF-7) and human hepatocellular carcinoma (Hep-G2) cell lines for compound 1, 2 and 8 were evaluated. Compound 1 exhibited cytotoxic activity towards MCF-7 and Hep-G2 cell lines with the IC 50 values 38.2 and 39.5 μM, respectively. Moreover, compound 2 showed weak cytotoxic activities against the two cell lines.

    Bacterial biofilms are associated with a large number of persistent and chronic infections. Biofilm-dwelling bacteria are particularly resistant to antibiotics and immune defenses, which makes it hard if not impossible to eradicate biofilm-associated infections. In the urinary tract, free iron...... is strictly limited but is critical for bacterial growth. Biofilm-associated Escherichia coli cells are particularly desperate for iron. An attractive way of inhibiting biofilm formation is to fool the bacterial regulatory system for iron uptake. Here, we demonstrate that biofilm formation can be impaired...... by the addition of divalent metal ions, such as Zn(II) and Co(II), which inhibit iron uptake by virtue of their higher-than-iron affinity for the master controller protein of iron uptake, Fur. Reduced biofilm formation of urinary tract-infectious E. coli strains in the presence of Zn(II) was observed...

    Full Text Available Foraging behaviours used by two female Australian fur seals (Arctocephalus pusillus doriferus were documented during controlled feeding trials. During these trials the seals were presented with prey either free-floating in open water or concealed within a mobile ball or a static box feeding device. When targeting free-floating prey both subjects primarily used raptorial biting in combination with suction, which was used to draw prey to within range of the teeth. When targeting prey concealed within either the mobile or static feeding device, the seals were able to use suction to draw out prey items that could not be reached by biting. Suction was followed by lateral water expulsion, where water drawn into the mouth along with the prey item was purged via the sides of the mouth. Vibrissae were used to explore the surface of the feeding devices, especially when locating the openings in which the prey items had been hidden. The mobile ball device was also manipulated by pushing it with the muzzle to knock out concealed prey, which was not possible when using the static feeding device. To knock prey out of this static device one seal used targeted bubble blowing, where a focused stream of bubbles was blown out of the nose into the openings in the device. Once captured in the jaws, prey items were manipulated and re-oriented using further mouth movements or chews so that they could be swallowed head first. While most items were swallowed whole underwater, some were instead taken to the surface and held in the teeth, while being vigorously shaken to break them into smaller pieces before swallowing. The behavioural flexibility displayed by Australian fur seals likely assists in capturing and consuming the extremely wide range of prey types that are targeted in the wild, during both benthic and epipelagic foraging.

    PerR, a member of Fur family protein, is a metal-dependent H 2 O 2 sensing transcription factor that regulates genes involved in peroxide stress response. Industrially important bacterium Bacillus licheniformis contains three PerR-like proteins (PerR BL , PerR2, and PerR3) compared to its close relative Bacillus subtilis. Interestingly, unlike other bacteria including B. subtilis, no authentic perR BL null mutant could be established for B. licheniformis. Thus, we constructed a conditional perR BL mutant using a xylose-inducible promoter, and investigated the genes under the control of PerR BL . PerR BL regulon genes include katA, mrgA, ahpC, pfeT, hemA, fur, and perR as observed for PerR BS . However, there is some variation in the expression levels of fur and hemA genes between B. subtilis and B. licheniformis in the derepressed state. Furthermore, katA, mrgA, and ahpC are strongly induced, whereas the others are only weakly or not induced by H 2 O 2 treatment. In contrast to the B. subtilis perR null mutant which frequently gives rise to large colony phenotype mainly due to the loss of katA, the suppressors of B. licheniformis perR mutant, which can form colonies on LB agar, were all catalase-positive. Instead, many of the suppressors showed increased levels of siderophore production, suggesting that the suppressor mutation is linked to the fur gene. Consistent with this, perR fur double mutant could grow on LB agar without Fe supplementation, whereas perR katA double mutant could only grow on LB agar with Fe supplementation. Taken together, our data suggest that in B. licheniformis, despite the similarity in PerR BL and PerR BS regulon genes, perR is an essential gene required for growth and that the inability of perR null mutant to grow is mainly due to elevated expression of Fur.

    California sea lions (Zalophus californianus) and northern fur seals (Callorhinus ursinus) are each believed to host distinct hookworm species (Uncinaria spp.). However, a recent morphometric analysis suggested that a single species parasitizes multiple pinniped hosts, and that the observed differences are host-induced. To explore the systematics of these hookworms and test these competing hypotheses, we obtained nucleotide sequences of nuclear ribosomal DNA (D2/D3 28S, D18/D19 28S, and internal transcribed spacer [ITS] regions) from 20 individual hookworms parasitizing California sea lion and northern fur seal pups where their breeding grounds are sympatric. Five individuals from an allopatric population of California sea lions were also sampled for ITS-1 and D18/D19 28S sequences. The 28S D2/D3 sequences showed no diagnostic differences among hookworms sampled from individual sea lions and fur seals, whereas the 28S D18/D19 sequences had one derived (apomorphic) character demarcating hookworms from northern fur seals. ITS sequences were variable for 7 characters, with 4 derived (apomorphic) states in ITS-1 demarcating hookworms from California sea lions. Multivariate analysis of morphometric data also revealed significant differences between nematodes representing these 2 host-associated lineages. These results indicate that these hookworms represent 2 species that are not distributed indiscriminately between these host species, but instead exhibit host fidelity, evolving independently with each respective host species. This evolutionary approach to analyzing sequence data for species delimitation is contrasted with similarity-based methods that have been applied to numerous diagnostic studies of nematode parasites.

    We have prepared mouse fur extensively {sup 13}C,{sup 15}N-labelled in all amino acid types enabling application of 2D solid state NMR techniques which establish covalent and spatial proximities within, and in favorable cases between, residues. {sup 13}C double quantum–single quantum correlation and proton driven spin diffusion techniques are particularly useful for resolving certain amino acid types. Unlike 1D experiments on isotopically normal material, the 2D methods allow the chemical shifts of entire spin systems of numerous residue types to be determined, particularly those with one or more distinctively shifted atoms such as Gly, Ser, Thr, Tyr, Phe, Val, Leu, Ile and Pro. Also the partial resolution of the amide signals into two signal envelopes comprising of α-helical, and β-sheet/random coil components, enables resolution of otherwise overlapped α-carbon signals into two distinct cross peak families corresponding to these respective secondary structural regions. The increase in resolution conferred by extensive labelling offers new opportunities to study the chemical fate and structural environments of specific atom and amino acid types under the influence of commercial processes, and therapeutic or cosmetic treatments.

  19. Bleaching of melanin in the epidermis of South American fur seal and its application on enzyme immunohistochemistry

    2011-03-01

    Full Text Available The South American fur seal (Arctocephalus australis is an amphibious marine mammal distributed along the Atlantic and Pacific coasts of South America. The species is well adjusted to different habitats due to the morphology of its fin-like members and due to some adaptations in their integumentary system. Immunohistochemical studies are very important to evaluate the mechanisms of skin adaptation due the differential expression of the antigens present in the tissue depending of the region of the body surface. However, its strongly pigmented (melanin epidermis prevents the visualization of the immuno-histochemical chromogens markers. In this study a melanin bleaching method was developed aimed to allow the visualization of the chromogens without interfering in the antigen-antibody affinity for immunohistochemistry. The analysis of PCNA (proliferating cell nuclear antigen index in the epidermis of A. australis by immunohistochemistry with diaminobenzidine (DAB as chromogen was used to test the method. The bleaching of the melanin allowed to obtain the cell proliferation index in epidermis and to avoid false positive results without affecting the immunohistochemical results.

    Human-induced changes to habitats can have deleterious effects on many species that occupy them. However, some species can adapt and even benefit from such modifications. Artificial reefs have long been used to provide habitat for invertebrate communities and promote local fish populations. With the increasing demand for energy resources within ocean systems, there has been an expansion of infrastructure in near-shore benthic environments which function as de facto artificial reefs. Little is known of their use by marine mammals. In this study, the influence of anthropogenic sea floor structures (pipelines, cable routes, wells and shipwrecks) on the foraging locations of 36 adult female Australian fur seals (Arctocephalus pusillus doriferus) was investigated. For 9 (25%) of the individuals, distance to anthropogenic sea floor structures was the most important factor in determining the location of intensive foraging activity. Whereas the influence of anthropogenic sea floor structures on foraging locations was not related to age and mass, it was positively related to flipper length/standard length (a factor which can affect manoeuvrability). A total of 26 (72%) individuals tracked with GPS were recorded spending time in the vicinity of structures (from 75% of the foraging trip duration) with pipelines and cable routes being the most frequented. No relationships were found between the amount of time spent frequenting anthropogenic structures and individual characteristics. More than a third (35%) of animals foraging near anthropogenic sea floor structures visited more than one type of structure. These results further highlight potentially beneficial ecological outcomes of marine industrial development.

    Full Text Available Dive characteristics and dive shape are often used to infer foraging success in pinnipeds. However, these inferences have not been directly validated in the field with video, and it remains unclear if this method can be applied to benthic foraging animals. This study assessed the ability of dive characteristics from time-depth recorders (TDR to predict attempted prey capture events (APC that were directly observed on animal-borne video in Australian fur seals (Arctocephalus pusillus doriferus, n=11. The most parsimonious model predicting the probability of a dive with ≥1 APC on video included only descent rate as a predictor variable. The majority (94% of the 389 total APC were successful, and the majority of the dives (68% contained at least one successful APC. The best model predicting these successful dives included descent rate as a predictor. Comparisons of the TDR model predictions to video yielded a maximum accuracy of 77.5% in classifying dives as either APC or non-APC or 77.1% in classifying dives as successful verses unsuccessful. Foraging intensity, measured as either total APC per dive or total successful APC per dive, was best predicted by bottom duration and ascent rate. The accuracy in predicting total APC per dive varied based on the number of APC per dive with maximum accuracy occurring at 1 APC for both total (54% and only successful APC (52%. Results from this study linking verified foraging dives to dive characteristics potentially opens the door to decades of historical TDR datasets across several otariid species.

    Surviving prolonged fasting requires various metabolic adaptations, such as energy and protein sparing, notably when animals are simultaneously engaged in energy-demanding processes such as growth. Due to the intermittent pattern of maternal attendance, subantarctic fur seal pups have to repeatedly endure exceptionally long fasting episodes throughout the 10-mo rearing period while preparing for nutritional independence. Their metabolic responses to natural prolonged fasting (33.4 +/- 3.3 days) were investigated at 7 mo of age. Within 4-6 fasting days, pups shifted into a stage of metabolic economy characterized by a minimal rate of body mass loss (0.7%/day) and decreased resting metabolic rate (5.9 +/- 0.1 ml O(2)xkg(-1)xday(-1)) that was only 10% above the level predicted for adult terrestrial mammals. Field metabolic rate (289 +/- 10 kJxkg(-1)xday(-1)) and water influx (7.9 +/- 0.9 mlxkg(-1)xday(-1)) were also among the lowest reported for any young otariid, suggesting minimized energy allocation to behavioral activity and thermoregulation. Furthermore, lean tissue degradation was dramatically reduced. High initial adiposity (>48%) and predominant reliance on lipid catabolism likely contributed to the exceptional degree of protein sparing attained. Blood chemistry supported these findings and suggested utilization of alternative fuels, such as beta-hydroxybutyrate and de novo synthesized glucose from fat-released glycerol. Regardless of sex and body condition, pups tended to adopt a convergent strategy of extreme energy and lean body mass conservation that appears highly adaptive for it allows some tissue growth during the repeated episodes of prolonged fasting they experience throughout their development.

    The furs of mammals have varied and complex functions. Other than for thermoregulation, fur is involved in physical protection, sensory input, waterproofing and colouration, the latter being important for crypsis or camouflage. Some of these diverse functions potentially conflict. We have investigated how variation in cryptic colouration and thermal features may interact in the coats of mammals and influence potential heat inflows from solar radiation, much of which is outside the visible spectral range. The coats of the polar bear (Ursus maritimus) and the marsupial koala (Phascolarctus cinereus) have insulative similarities but, while they feature cryptic colouration, they are of contrasting colour, i.e. whitish and dark grey. The reflectance of solar radiation by coats was measured across the full solar spectrum using a spectroradiometer. The modulation of incident solar radiation and resultant heat flows in these coats were determined at a range of wind speeds by mounting them on a heat flux transducer/temperature-controlled plate apparatus in a wind tunnel. A lamp with a spectral distribution of radiation similar to the solar spectrum was used as a proxy for the sun. Crypsis by colour matching was apparent within the visible spectrum for the two species, U. maritimus being matched against snow and P. cinereus against Eucalyptus forest foliage. While reflectances across the full solar spectrum differed markedly, that of U. maritimus being 66 % as opposed to 10 % for P. cinereus, the heat influxes from solar radiation reaching the skin were similar. For both coats at low wind speed (1 m s(-1)), 19 % of incident solar radiation impacted as heat at the skin surface; at higher wind speed (10 m s(-1)) this decreased to approximately 10 %. Ursus maritimus and P. cinereus have high and comparable levels of fur insulation and although the patterns of reflectance and depths of penetrance of solar radiation differ for the coats, the considerable insulation limited the

    A prevalence survey for hookworms (Uncinaria spp.) was done in northern fur seal (Callorhinus ursinus) and California sea lion (Zalophus californianus) pups on San Miguel Island, CA, in 2000. Intestines of dead pups were examined for adult hookworms in July. These parasites were found in 95% of 20 fur seal pups and 100% of 31 sea lion pups. The number of hookworms varied from 4 to 2142 (mean = 760) in fur seal pups and from 20 to 2634 (mean = 612) in sea lion pups. A direct relationship was evident between body condition and number of hookworms in the pups; that is, pups in poor condition had fewer hookworms than those in good condition. There was a decline in the number of hookworms in sea lion pups in 2000 compared to collections in 1996. Eggs of Uncinaria spp. were found in rectal feces (collected in late September and early October) of none of 35 (0%) live fur seal pups and 41 of 48 (85%) live sea lion pups. Packed cell volume values, determined for most of the same live pups, were essentially normal for C. ursinus but were much lower than normal for most Z. californianus. Hookworm larvae were not found in blubber of fur seal and sea lion pups or in rookery sand in July. Rookery sand, positive for live hookworm larvae when put in a refrigerator, was negative at removal 2.5 years later. The average number of eggs in utero of female hookworms was 285 for three specimens from a fur seal pup and 281 from three specimens from a sea lion pup. One hookworm larva was recovered from milk stripped from the teats of a stranded Z. californianus female at The Marine Mammal Center, Sausalito, CA.

    Cycloaddition reactions are among the most important tools for synthesis in organic chemistry, since these reactions are vital to the modern synthesis of natural products and biologically active substances. Metal catalysis plays an increasingly important role in these reactions, often allowing several stereocenters to be selectively created and integrated in the target molecules. Kobayashi and Jorgensen's handbook provides numerous examples of metal-catalyzed reactions, including [2+1], [3+2] and [4+2] cycloadditions. Important reactions such as carbo- and hetero-Diels-Alder, carbocyclic, cyclopropanation and 1,3-dipolar cycloaddition reactions are discussed. A large number of experimental procedures gives a concrete idea of the use of metal-catalyzed cycloaddition reactions in modern synthesis. The book is aimed at chemists in industry or academia, who want to effectively use cycloadditions in their work.

    In order to clarify the chemical behaviour of Americium in saline aqueous systems relevant for final storage this study deals with the chemical reactions of trivalent and pentavalent Americium in NaCl-solutions under the influence of radiolysis from its own alpha radiation. The focus of the study was on investigating the geologically relevant reactions, such as hydrolysis or carbonate- and chloride complexing in solid-liquid equilibriums. Comprehensive measurements on solubility and spectroscopic studies in NaCl-solutions were carried out in a CO{sub 2}-free atmosphere and 10{sup -2} atm CO{sub 2} partial pressure. Identification and characterisation of the AM (III) and AM(V) solid phases were supplemented by structural research with the chemically analogue EU (III) and Np(V) compounds. The alpha-radiation induced radiolysis in saline NaCl solutions and the redox behaviour of Americium which was influenced thereby were spectroscopically quantified. (orig.)

    The Deutsche Forschungsanstalt fur Psychiatrie (DFA) in Munich, one of the most important research institutes in the field of theoretical and clinical psychiatry, was founded in 1917 by Emil Kraepelin. Its financial existence between the world wars was assured by generous donations from the Jewish American scholar and philanthropist James Loeb. The scientific work done by Walther Spielmeyer (neuropathology), Felix Plaut (serology), Kurt Schneider (clinical psychiatry) and Ernst Rudin (psychiatric genetics) earned the DFA a reputation as an international center for psychiatry and neurology. During the 'Third Reich' Ernst Rudin cooperated with the National Socialist health system. His genetic concepts provided support for eugenic programmes such as forced sterilization of individuals with psychoses. These complex interactions underscore the importance of the DFA in understanding the recent history of medicine in Germany.

    Thoracic auscultation is an important diagnostic method used in cases of suspected pulmonary disease in many species, as respiratory sounds contain significant information on the physiology and pathology of the lungs and upper airways. Respiratory diseases are frequent in marine mammals and are often listed as one of their main causes of death. The aim of this study was to investigate and report baseline parameters for the electronic-mediated thoracic auscultation of one cetacean species and two pinniped species in captivity. Respiratory sounds from 20 captive bottlenose dolphins (Tursiops truncatus), 6 California sea lions (Zalophus californianus), and 5 South African fur seals (Arctocephalus pusillus) were recorded with an electronic stethoscope. The sounds were analyzed for duration of the respiratory cycle, adventitious sounds, and peak frequencies of recorded sounds during expiration and inspiration as well as for sound intensity as reflected by waveform amplitude during the respiratory cycle. In respiratory cycles of the bottlenose dolphins' expiring "on command," the duration of the expiration was significantly shorter than the duration of the inspiration. In the examined pinnipeds of this study, there was no clear pattern concerning the duration of one breathing phase: Adventitious sounds were detected most often in bottlenose dolphins that were expiring on command and could be compared with "forced expiratory wheezes" in humans. This is the first report of forced expiratory wheezes in bottlenose dolphins; they can easily be misinterpreted as pathologic respiratory sounds. The peak frequencies of the respiratory sounds reached over 2,000 Hz in bottlenose dolphins and over 1,000 Hz in California sea lions and South African fur seals, but the variation of the frequency spectra was very high in all animals. To the authors' knowledge, this is the first systematic analysis of respiratory sounds of bottlenose dolphins and two species of pinnipeds.

    The peritoneal cavity (PNC) and intestine of northern fur seal (Callorhinus ursinus) pups and California sea lion (Zalophus californianus) pups that died in late July and early August, 2003, on San Miguel Island, California, were examined for hookworms. Prevalence and morphometric studies were done with the hookworms in addition to molecular characterization. Based on this and previous molecular studies, hookworms from fur seals are designated as Uncinaria lucasi and the species from sea lions as Uncinaria species A. Adult hookworms were found in the PNC of 35 of 57 (61.4%) fur seal pups and of 13 of 104 (12.5%) sea lion pups. The number of hookworms located in the PNC ranged from 1 to 33 (median = 3) for the infected fur seal pups and 1 to 16 (median = 2) for the infected sea lion pups. In addition to the PNC, intestines of 43 fur seal and 32 sea lion pups were examined. All of these pups were positive for adult hookworms. The worms were counted from all but one of the sea lion pups. Numbers of these parasites in the intestine varied from 3 to 2,344 (median = 931) for the fur seal pups and 39 to 2,766 (median = 643) for the sea lion pups. Sea lion pups with peritoneal infections had higher intensity infections in the intestines than did pups without peritoneal infections, lending some support for the hypothesis that peritoneal infections result from high-intensity infections of adult worms. There was no difference in intestinal infection intensities between fur seal pups with and without peritoneal infections. Female adult hookworms in the intestines of both host species were significantly larger than males, and sea lion hookworms were larger than those in fur seals. Worms in the intestine also were larger than worms found in the PNC. Gene sequencing and (RFLP) analysis of (PCR) amplified (ITS) ribosomal DNA were used to diagnose the species of 172 hookworms recovered from the PNC and intestine of 18 C. ursinus and seven Z. californianus hosts

    Full Text Available En este trabajo se evaluaron los cambios en densidad y longitud del pelaje dorsal y ventral en el roedor subterráneo Ctenomys talarum, como posible mecanismo compensatorio frente a cambios de temperatura estacionales en el ambiente de la cueva, en especial durante la época estival, y durante el período de preñez en las hembras, ya que ambas etapas representan desafíos para la termorregulación en esta especie. Se observó que el pelaje ventral fue significativamente más corto y menos denso que el dorsal en machos, hembras preñadas y hembras no preñadas en las dos estaciones evaluadas. La longitud del pelaje tanto dorsal como ventral en los tres grupos fue significativamente menor durante la estación de temperaturas más cálidas. En la estación cálida, las hembras preñadas exhibieron un pelaje ventral significativamente más corto que el pelaje ventral de machos y de hembras no preñadas. Se discuten las posibles ventajas térmicas que podrían representar las modificaciones observadas en las características del pelaje de esta especie, con énfasis en las restricciones que impone el ambiente subterráneo en cuanto a los mecanismos disponibles de disipación del calor corporalIn this work, the changes in fur density and length in the subterranean rodent Ctenomys talarum were evaluated as a possible compensatory mechanism during seasonal temperature changes in their burrow environment and during pregnancy in females, both situations being thermoregulatory challenging in this species. The ventral fur was shorter and less dense than the dorsal fur in the three groups (males, non-pregnant females and pregnant females and in the two seasons evaluated. Ventral and dorsal furs were significantly shorter during the warm seasons in the three groups. In the warm season, pregnant females had a ventral fur significantly shorter than that of males and non-pregnant females. The possible thermal advantages that the observed fur changes might

    The small-tail Han sheep and the Surabaya fur sheep are two local breeds in north China, which are characterized by high-fecundity and low-prolificacy breed respectively. Significant genetic differences between these two breeds have provided increasing interests in the identification and utilization of major prolificacy genes in these sheep. High prolificacy is a complex trait, and it is difficult to comprehensively identify the candidate genes related to this trait using the single molecular biology technique. To understand the molecular mechanisms of fecundity and provide more information about high prolificacy candidate genes in high- and low-fecundity sheep, we explored the utility of next-generation sequencing technology in this work. A total of 1.8 Gb sequencing reads were obtained and resulted in more than 20 000 contigs that averaged ∼300 bp in length. Ten differentially expressed genes were further verified by quantitative real-time RT-PCR to confirm the reliability of RNA-seq results. Our work will provide a basis for the future research of the sheep reproduction.

    Studies on several aspects of the life cycle of hookworms (Uncinaria spp.) in the California sea lion (Zalophus californianus) and northern fur seal (Callorhinus ursinus) were conducted on material collected on San Miguel Island (SMI), California and at The Marine Mammal Center, Sausalito, California in 1997, 1998, and 1999. Examination of Z. californianus intestines for adult hookworms and feces for eggs revealed that longevity of these parasites in pups is about 6-8 mo, and infections are probably not present in older sea lions. Parasitic third-stage larvae (L3) were recovered from the ventral abdominal tissue of Z. californianus, suggesting transmammary transmission. Callorhinus ursinus pups had no hookworm eggs in their feces or adult worms (except for 1 probable contaminant) in their intestines in the fall and early winter, revealing that adult Uncinaria spp. are spontaneously lost at <3 mo of age of the pups. Sand samples from rookeries, used by both Z. californianus and C. ursinus, on SMI were negative for free-living, L3 in summer months but positive in fall and winter months, indicating seasonality occurred.

    1992-07-01

    The investigation analyses the potentials and consequences of using natural gas as a fuel for the ferry used for the Branden-Fur crossing in Denmark. The installation cost of a gas engine is stated to be 1,521,000 Danish kroner for a single engine, or 2,146,000 kroner for a twin engine. Costs of design work, installation in the vessel etc., would be 150,000 kr. and installation on shore would cost 760,000 Danish kroner. Natural gas operation based on a compact type engine, e.g. MAN, MTU and MWM, output range approx. 300 kW., is recommended. Environmental impact is estimated to be in the case of natural gas use, NO x 2.8, CO 3.6, HC 0.8 and CO 2 , 892 kg per day, all of which is very significantly less than that expected from a diesel engine, i.e. NO x emission would be reduced by 75% and particulates by 90%. Single engines pollute less. N-gas engines also make far less noise. A balance in fuel and maintenenace costs can be achieved providing the gas can be supplied at a price, as of April 1st, 1992, of 0.85 Danish kroner per m 3 n excluding all taxes. Tank installation can be incorporated as a more integral embodiment of the ferry design. It is recommended that a central natural gas-fired engine should be installed with direct mechanical transmission to the propellers at either end of the ship. It is required that a secure supply of an end-product, ''CNG 200 bar'' be established for ferry operations at a competitive price throughout the entire depreciation period for engine and installation.

    Behavioral responses by top marine predators to oceanographic features such as eddies, river plumes, storms, and coastal topography suggest that biophysical interactions in these zones affect predators' prey, foraging behaviors, and potentially fitness. However, examining these pathways is challenged by the obstacles inherent in obtaining simultaneous observations of surface and subsurface environmental fields and predator behavior. In this study, migratory movements and, in some cases, diving behavior of 40 adult female northern fur seals (NFS; Callorhinus ursinus) were quantified across their range and compared to remotely-sensed environmental data in the Gulf of Alaska and California Current ecosystems, with a particular focus off the coast of Washington State (USA)--a known foraging ground for adult female NFS and where autonomous glider sampling allowed opportunistic comparison of seal behavior to subsurface biophysical measurements. The results show that in these ecosystems, adult female habitat utilization was concentrated near prominent coastal topographic, riverine, or inlet features and within 200 km of the continental shelf break. Seal dive depths, in most ecosystems, were moderated by surface light level (solar or lunar), mirroring known behaviors of diel vertically-migrating prey. However, seal dives differed in the California Current ecosystem due to a shift to more daytime diving concentrated at or below the surface mixed layer base. Seal movement models indicate behavioral responses to season, ecosystem, and surface wind speeds; individuals also responded to mesoscale eddies, jets, and the Columbia River plume. Foraging within small scale surface features is consistent with utilization of the inner coastal transition zone and habitats near coastal capes, which are known eddy and filament generation sites. These results contribute to our knowledge of NFS migratory patterns by demonstrating surface and subsurface behavioral responses to a spatially

    Full Text Available Adult male and female northern fur seals (Callorhinus ursinus are sexually segregated in different regions of the North Pacific Ocean and Bering Sea during their winter migration. Explanations for this involve interplay between physiology, predator-prey dynamics, and ecosystem characteristics, however possible mechanisms lack empirical support. To investigate factors influencing the winter ecology of both sexes, we deployed five satellite-linked conductivity, temperature, and depth data loggers on adult males, and six satellite-linked depth data loggers and four satellite transmitters on adult females from St. Paul Island (Bering Sea, Alaska, USA in October 2009. Males and females migrated to different regions of the North Pacific Ocean: males wintered in the Bering Sea and northern North Pacific Ocean, while females migrated to the Gulf of Alaska and California Current. Horizontal and vertical movement behaviors of both sexes were influenced by wind speed, season, light (sun and moon, and the ecosystem they occupied, although the expression of the behaviors differed between sexes. Male dive depths were aligned with the depth of the mixed layer during daylight periods and we suspect this was the case for females upon their arrival to the California Current. We suggest that females, because of their smaller size and physiological limitations, must avoid severe winters typical of the northern North Pacific Ocean and Bering Sea and migrate long distances to areas of more benign environmental conditions and where prey is shallower and more accessible. In contrast, males can better tolerate often extreme winter ocean conditions and exploit prey at depth because of their greater size and physiological capabilities. We believe these contrasting winter behaviors 1 are a consequence of evolutionary selection for large size in males, important to the acquisition and defense of territories against rivals during the breeding season, and 2 ease environmental

    Coconut oil is commonly used as herbal medicine worldwide. There is limited information regarding its effects on the developing embryo and infant growth. We investigated the effect of virgin coconut oil post-natally and until 6 weeks old in mice (age of maturity). Females were fed with either standard, virgin olive oil or virgin coconut oil diets 1 month prior to copulation, during gestation and continued until weaning of pups. Subsequently, groups of pups borne of the respective diets were continuously fed the same diet as its mother from weaning until 6 weeks old. Profiles of the standard and coconut oil diets were analysed by gas chromatography flame ionization detector (GCFID). Analysis of the mean of the total weight gained/ loss over 6 weeks revealed that in the first 3 weeks, pups whose mothers were fed virgin coconut oil and virgin olive oil have a significantly lower body weight than that of standard diet pups. At 6 weeks of age, only virgin coconut oil fed pups exhibited significantly lower body weight. We report that virgin coconut oil modifies the fatty acid profiles of the standard diet by inducing high levels of medium chain fatty acids with low levels of essential fatty acids. Furthermore, pups borne by females fed with virgin coconut oil developed spiky fur. Our study has demonstrated that virgin coconut oil could affect infant growth and appearance via maternal intake; we suggest the use of virgin coconut oil as herbal medicine to be treated with caution.

    Full Text Available The skull morphometrics of adult male Antarctic fur seal, Arctocephalus gazella (Peters, 1875 and South American fur seal, A. australis (Zimmermann, 1783 were investigated using a collection of 45 and 38 skulls, respectively. Eighteen measurements were taken for each specimen. Comparative univariate and multivariate statistical analyses included standard statistics, one-way analysis of variance, principal component analysis and discriminant analysis. Individual variation was relatively high for some variables, as expressed by the coefficient of variation. Skulls of A. gazella were larger than those of A. australis for all but two variables: squamosal jugal suture and rostral length. Both species differed significantly as shown by both univariate and multivariate analyses. The discriminant function correctly classified all specimens. The standardized canonical coefficients showed that the variables which most contribute to the differentiation between species were, in decreasing order, the rostral length, palatal length, palatal width at postcanine 5 and braincase width. The present study corroborates that A. gazella and A. australis are phenotipically distinct species.Se estudió la morfometría craneana de especímenes machos adultos de lobo fino Antártico, Arctocephalus gazella (Peters, 1875 y lobo fino sudamericano, A. australis (Zimmermann, 1783, consultando una colección de 45 y 38 cráneos respectivamente. Para cada ejemplar se tomó un total de 18 medidas. El análisis comparativo univariado y multivariado incluyó estadística standard, análisis de varianza, análisis de componentes principales y análisis discriminante. La variación individual, según lo expresado por el coeficiente de variación, fue relativamente alta para algunas variables. Los cráneos de A. gazella fueron proporcionalmente más grandes que aquellos de A. australis para todas las variables estudiadas, excepto dos: longitud de la sutura escamoso-yugal y longitud

    Full Text Available Translation of culture-bound terms is of special importance in translation theory and practice. The present study is an attempt to examine the procedures used in translating these terms in the English translations of the Holy Qur’an. As such, English equivalents of terms related to Practical laws of religion (Furū al-Dīn in five English versions of the Qur'an are identified and the translation procedures used in them in addition to the frequency of occurrence of each procedure have been examined. The study reveals that literal translation is not only the most frequently used procedure but also the most appropriate one in translating such terms.

The score for the three other measures also varied with date of assessment but not enough to affect the classification. However, the observed change in the four measures we focused on indicates that a change in the overall Wel......Fur classification can occur if these or other measures change a little more for the better or worse.

    Full Text Available Abstract In order to effectively identify the vaccine and field strains of Canine distemper virus (CDV, a new differential diagnostic test has been developed based on reverse transcription-polymerase chain reaction (RT-PCR and restriction fragment length polymorphism (RFLP. We selected an 829 bp fragment of the nucleoprotein (N gene of CDV. By RFLP analysis using BamHI, field isolates were distinguishable from the vaccine strains. Two fragments were obtained from the vaccine strains by RT-PCR-RFLP analysis while three were observed in the field strains. An 829 nucleotide region of the CDV N gene was analyzed in 19 CDV field strains isolated from minks, raccoon dogs and foxes in China between 2005 and 2007. The results suggest this method is precise, accurate and efficient. It was also determined that three different genotypes exist in CDV field strains in fur animal herds of the north of China, most of which belong to Asian type. Mutated field strains, JSY06-R1, JSY06-R2 and JDH07-F1 also exist in Northern China, but are most closely related to the standard virulent strain A75/17, designated in Arctic and America-2 genetype in the present study, respectively.

    The filamentous cyanobacterium Nostoc sp. strain PCC 7120 can fix N2 when combined nitrogen is not available. Furthermore, it has to cope with reactive oxygen species generated as byproducts of photosynthesis and respiration. We have previously demonstrated the synthesis of Ser/Thr kinase Pkn22 as an important survival response of Nostoc to oxidative damage. In this study we wished to investigate the possible involvement of this kinase in signalling peroxide stress and nitrogen deprivation. Quantitative RT-PCR experiments revealed that the pkn22 gene is induced in response to peroxide stress and to combined nitrogen starvation. Electrophoretic motility assays indicated that the pkn22 promoter is recognized by the global transcriptional regulators FurA and NtcA. Transcriptomic analysis comparing a pkn22-insertion mutant and the wild type strain indicated that this kinase regulates genes involved in important cellular functions such as photosynthesis, carbon metabolism and iron acquisition. Since metabolic changes may lead to oxidative stress, we investigated whether this is the case with nitrogen starvation. Our results rather invalidate this hypothesis thereby suggesting that the function of Pkn22 under nitrogen starvation is independent of its role in response to peroxide stress. Our analyses have permitted a more complete functional description of Ser/Thr kinase in Nostoc. We have decrypted the transcriptional regulation of the pkn22 gene, and analysed the whole set of genes under the control of this kinase in response to the two environmental changes often encountered by cyanobacteria in their natural habitat: oxidative stress and nitrogen deprivation.

    Full Text Available The abundance of California sea lions (Zalophus californianus (CSLs and Guadalupe fur seals (Arctocephalus philippii townsendi (GFSs from the San Benito Archipelago (SBA was determined through nine monthly surveys in 2014-2015. Assessment of their foraging habits was examined based on the isotopic analysis of pups (maternal indicators (SIAR/SIBER-R. Environmental variability between 2014 and 2015 was also analyzed, in terms of sea surface temperature (SST and chlorophyll (Chl-a concentration. Both otariids reached their highest abundance in July of both years; however, relative to 2014, the 2015 survey showed a 59.7% decline in the total GFS abundance and a 42.9% decrease of GFS pups, while total CSL abundance decreased 52.0% and CSL pup presence decreased in 61.7%. All monthly surveys for both otariids showed a similar trend (>50% decrease in 2015. Compared to 2014, the 2015 GFSs isotopic niche was three times larger (2.0 in 2015, 0.6 in 2014 and the δ13C was significantly lower. CSLs also showed significantly lower δ13C and higher δ15N in 2015. Interannual segregation was greater for CSLs, and their pup body mass was also significantly lower during the 2015 breeding season (mean = 8.7 kg than in the same season of 2014 (mean = 9.9 kg. The decrease in δ13C for both otariids reflected a more oceanic foraging; most likely associated with the decline in primary productivity in surrounding areas to the SBA, related to a higher SST caused by the 2015 ENSO, with a subsequent increase in foraging effort. These would explain the fewer observed individuals on land, especially pups, which showed diminished body condition (CSLs. This study highlights the importance of marine mammals as sentinel species that respond dynamically to changes in environment, providing valuable information on the effect of ENSO on pinnipeds in Mexican waters.

    Full Text Available During the survey of epigeous spider communities in the Bavarian Alps (Germany, Upper Bavaria, three species of Erigoninae were recorded from Germany for the first time. Micrargus alpinus and Silometopus rosemariae are endemic species of the Alps, Panamomops palmgreni is endemic to the Alpine mountain system. For each species present knowledge on distribution, habitat and phenology is summarized. As Micrargus alpinus was described in 1997, faunistic and ecological data are still very poor. Niche differentiation between the closely related species of the Micrargus herbigradus-group is discussed.

    Why did the Dutch come to the North American shores 400 years ago? Was it wanderlust, expansionist policies, or simply money? The earliest western explorers were the Vikings who, in the 1100s, were able to sail beyond Iceland and Greenland to Newfoundland, because they did so during the Medieval Warm Period. English explorer Henry Hudson, on the other hand, could not find a northern passage to China because the early 1600s were the coldest part of the Little Ice Age and the northern seas were frozen over (Figure 1).After Hudson's third voyage, Dutch merchants contracted several sailors to establish trading posts for beaver pelts in the Americas. Among them was Adriaen Block, who built the first western settlement on the island of Manhattan (New York) after a fire on his ship forced him to over-winter there in 1614 [Varekamp and Varekamp, 2006]. His 1614 'figurative map' shows Long Island Sound as an estuary, and introduced for the first time the name 'Niew Nederlandt' (New Netherlands).

    Full Text Available L’utilisation des myriapodes en friction sur le pelage et d’autres zones corporelles est documentée chez les primates en conditions naturelles, notamment à partir des observations récurrentes menées chez le genre Cebus. La typologie de ces comportements suggère différentes hypothèses, fonctionnelles (zoopharmacognosie, alimentaire, sociale ou non (sensorielle, auto-stimulation. Nous présentons des observations qualitatives comparées de l’utilisation non alimentaire de myriapodes diplopodes chez une forme hybride du genre Eulemur au Sud de Madagascar (occurrences en janvier 2005 et chez le sapajou Cebus apella en Guyane Française (occurrences en mars-avril 1996. L’application des sécrétions à benzoquinones sur une large partie du pelage chez Cebus contraste avec la friction exclusive de la zone périgénitale faisant suite au flairage du diplopode chez Eulemur qui manifeste en outre une réponse stéréotypée analogue au flehmen. Dans notre étude, l’imprégnation de fluides à forte intensité olfactive potentialiserait la signalisation de l’identité individuelle chez Eulemur alors que le "fur-rubbing" chez Cebus est compatible avec l’hypothèse commune d’une forme d’appropriation des défenses antiparasitaires de ces invertébrés.

    Full Text Available Infectious diseases in wild animals have been increasing as a result of their habitat alterations and closer contact with domestic animals. Canine distemper virus (CDV has been reported in several species of wild carnivores, presenting a threat to wildlife conservation. We described the first case of canine distemper virus infection in lesser grison (Galictis cuja. A free-ranging individual, with no visible clinical sigs, presented sudden death after one day in captivity. Molecular diagnosis for CDV infection was performed using whole blood collected by postmortem intracardiac puncture, which resulted positive. The virus phylogeny indicated that domestic dogs were the probable source of infection.Doenças infecciosas em animais selvagens têm aumentado devido às alterações em seu habitat e ao maior contato com animais domésticos.

    Full Text Available Exploitation of the Guadalupe fur seal (GFS during the XVIII and XIX centuries almost extirpated the species. GFS were distributed from the Revillagigedo islands (Mexico to the gulf of Farallones (USA. At present, reproductive colonies are found at Guadalupe Island and San Benito Archipelago (SBA. The aim of this work was to analyze the process of re-colonization and the current status of GFS at SBA. The first births and the occupation of the west island of the SBA are also reported. Census data from 1997 to 2007 indicated an annual growth rate for the population of 21.6%. The population size, growth tendency of the colony, reproductive biology, and food preferences were also studied. A total of 2,227 GFS were counted at SBA. Three squid species (Loligo opalescens, Onychoteuthis banksii, Dosidicus gigas were found to be the main dietary components. Territoriality, activity patterns, and reproductive behavior were similar for the seals from Guadalupe Island and SBA. The mean growth rate for pups from SBA was calculated and compared to that of the pups at Guadalupe Island (SBA: 6.7 ± 1.4 kg, 68.9 ± 2.64 cm; Guadalupe Island: 5.9 ± 0.5 kg, 67.29 ± 4.3 cm. The length of food foraging trips by females was measured, suggesting that the SBA colony is probably near an important feeding area. Maternal care patterns could indicate different strategies of nursing-foraging trips between the SBA and Guadalupe Island. The population of fur seals at SBA is expected to increase as there are no limitations in terms of reproductive space or available food resources in the area.La explotación del lobo fino de Guadalupe (LFG durante los siglos XVIII y XIX casi extinguió a la especie.

    IBACOS, in collaboration with GreenHomes America, was contracted by the New York State Energy Research and Development Authority to research exterior wall insulation solutions. This research investigated cost-effective deep energy retrofit (DER) solutions for improving the building shell exterior while achieving a cost-reduction goal, including reduced labor costs to reach a 50/50 split between material and labor. The strategies included exterior wall insulation plus energy upgrades as needed in the attic, mechanical and ventilation systems, and basement band joist, walls, and floors. The work can be integrated with other home improvements such as siding or window replacement. This strategy minimizes physical connections to existing wall studs, encapsulates existing siding materials (including lead paint) with spray foam, and creates a vented rain screen assembly to promote drying. GreenHomes America applied construction details created by IBACOS to a test home. 2x4 framing members were attached to the wall at band joists and top plates using 'L' clips, with spray foam insulating the wall after framing was installed. Windows were installed simultaneously with the framing, including extension jambs. The use of clips in specific areas provided the best strength potential, and 'picture framing' the spray foam held the 2x4s in place. Short-term testing was performed at this house, with monitoring equipment installed for long-term testing. Testing measurements will be provided in a later report, as well as utility impact (before and after), costs (labor and materials), construction time, standard specifications, and analysis for the exterior wall insulation strategy.

  15. Information system fur the management of a regulatory programme

    International Nuclear Information System (INIS)

    Ortiz, P.; Mrabit, K.; Miaw, S.

    1998-01-01

    A Regulatory Programme to monitor safety of activities involving radiation sources, implies the existence of a Regulatory Authority empowered by legislation to issue radiation protection regulations and to monitor compliance with those regulations. The core element of the programme is a system of notification and authorization (registration and licensing), inspection and enforcement. The efficiency of this system is largely dependent on the availability of reliable information on the inventory of radiation sources and installations, the administrative status of the facilities (authorization), prompt processing of inspection reports and follow up of regulatory actions, including monitoring deadlines. Essential data relevant to safety, such as personal dosimetry for occupationally exposed individuals, inspection findings and incident reports would provide, in addition, an insight on the overall safety of the country. A simple but comprehensive Regulatory Authority Information System (RAIS) linked to the authorization and inspection process will largely facilitate regulatory decisions and actions. A readily available and reliable information from the various regulatory activities will facilitate planning, optimization of resources, monitoring safety related data, disseminating safety information, making decisions and follow up regulatory actions including monitoring dead lines. The implementation of the system in more than 50 countries will contribute to experience exchange and harmonization of regulatory activities. (author)

    2011-01-01

    This dissertation describes a data compression system optimized for high energy particle detectors. The aim is to reduce the data in the front-end electronics installed in different kind of particle detectors as used for example along the Large Hadron Collider at CERN. The signals collected and digitized from calorimeters, time projection chambers and in general from all detectors with a large number of sensors produce an extensive amount of data, which need to be reduced. Real-time data compression algorithms applied right at the detector front-end is able to reduce the amount of data to be transmitted and stored as early as possible in the data chain. Different lossless and lossy compression methods are analyzed regarding their efficiency in compressing data from particle detectors that produce signals amplified and/or shaped to various waveforms. In addition, the complexity of the algorithms is evaluated to determine their suitability for a real-time hardware implementation. From the analyzed methods, a ne...

    2012-03-15

    The world has three big growth problems: The human race has doubled its number in the last 44 years. Their energy consumption has tripled over the same period. And also the emissions of greenhouse gases has grown faster than the number of people. If all the trends continue, they have the potential to disturb the ecological balance on the planet to such an extent that the living conditions of a growing part of humanity will be threatened. In a recent discussion paper by the Berlin Institute for population and development (Berlin, Federal Republic of Germany), the authors address the question of how to find a way out of this 'trilemma of growth'. The discussion paper provides concrete proposals for action for the implementation of the global energy turnaround. The education assumes an important role because it affects not only a moderating effect on the population growth. It also enables the handling of promising future technologies and facilitates the adjustment to the impending consequences of climate change.

    The contribution under consideration reports on an extensive modernization project at three small nearly identical constructed multi-family houses in Hofheim at Taunus (Federal Republic of Germany). The emphasis of this project is: (a) Realization of different energy saving measures (new building standard according to energy saving regulation, energy saving house-60-standard, energy saving house-40-standard); (b) Thermal protection of fascades by large sized, prefabricated insulating units in connection with vacuum isolation panels (large element damming technology). The damming concept successfully could be converted. The costs of the large element damming technology could be lowered in the model project on 900 Euro/square meters. The system saves a multiple of the energy necessary for the production due to the improved thermal protection.

  8. Three integrated photovoltaic/sound barrier power plants. Construction and operational experience; Drei integrierte PV-Schallschutz Versuchsfelder. Bau und Erprobung

    Energy Technology Data Exchange (ETDEWEB)

    Nordmann, T.; Froelich, A.; Clavadetscher, L.

    2002-07-01

    After an international ideas competition by TNC Switzerland and Germany in 1996, six companies where given the opportunity to construct a prototype of their newly developed integrated PV-sound barrier concepts. The main goal was to develop highly integrated concepts, allowing the reduction of PV sound barrier systems costs, as well as the demonstration of specific concepts for different noise situations. This project is strongly correlated with a German project. Three of the concepts of the competition are demonstrated along a highway near Munich, constructed in 1997. The three Swiss installations had to be constructed at different locations, reflecting three typical situations for sound barriers. The first Swiss installation was the world first Bi-facial PV-sound barrier. It was built on a highway bridge at Wallisellen-Aubrugg in 1997. The operational experience of the installation is positive. But due to the different efficiencies of the two cell sides, its specific yield lies somewhat behind a conventional PV installation. The second Swiss plant was finished in autumn 1998. The 'zig-zag' construction is situated along the railway line at Wallisellen in a densely inhabited area with some local shadowing. Its performance and its specific yield is comparatively low due to a combination of several reasons (geometry of the concept, inverter, high module temperature, local shadows). The third installation was constructed along the motor way A1 at Bruettisellen in 1999. Its vertical panels are equipped with amorphous modules. The report show, that the performance of the system is reasonable, but the mechanical construction has to be improved. A small trial field with cells directly laminated onto the steel panel, also installed at Bruettisellen, could be the key development for this concept. This final report includes the evaluation and comparison of the monitored data in the past 24 months of operation. (author)

Many of the well established automobile manufacturers are focusing their research and development activities on this upcoming technology. The big advantage of hybrid vehicles is the electrified powertrain. Due to intelligent combination of the combustion- and electric engine, the benefits of the two different powertrain configurations can be used. The following research is concerned and closely examines the role of the electric engine in the hybrid vehicle. The scope of the research is focused on the demands of an electric engine, the technical configuration, functionality and economy of three different engine types which are often used in the serial production and prototyping. In order to make a direct comparison of the performance of this different engine types, they were all tested in a go-cart. The go-carts for each engine were constructed in the same way. The interpretation of the measurement results showed that the synchronous engine with permanent magnets had the best performance when considering the level of electrical efficiency, closely followed by the switched reluctance motor. The efficiency of the electrical motor makes a high contribution to the total efficiency of the vehicle. The measurement result confirms the selection of a synchronous motor is, under consideration of the electrical efficiency, the most advantageous solution for hybrid vehicles. (orig.)

    Full Text Available Das Buch präsentiert mit der Berufsbiographie von Josefine Erkens die Schwierigkeiten in den ersten Jahrzehnten des letzten Jahrhunderts, einen für Frauen neuen Berufszweig zu etablieren. Neben Modernisierungsbestrebungen in der Polizei als solcher bestimmen sozialpolitische Reformbemühungen eines Teils der Frauenbewegung sowie Professionalisierung von Frauenarbeit die Durchsetzung dieses neuen Berufsfeldes. Doch unterschiedliche Konzepte zum Berufsbild der weiblichen Polizistin, die vorherrschende Nichtakzeptanz von Frauen in Führungspositionen sowie eine ablehnende, mißtrauische Haltung zu berufstätigen Frauen markieren die Hindernisse des vorgestellten beruflichen Lebenslaufs.Taking the professional biography of Josephine Erkens as an example, this book traces the difficulties women had to face when trying to establish a new branch of an occupation during the first few decades of the last century. Apart from efforts at modernization within the police force itself, social political strivings for reform of a part of the women’s movement as well as processes of professionalization were instrumental in the establishment of this new branch. However, different concepts of the job outline of policewomen, the prevailing non-recognition of women in positions of leadership as well as a negative and suspicious attitude towards working women greatly impeded this professional biography.

  16. The FUR to near-IR morphologies of luminous infrared galaxies in the goals sample

    International Nuclear Information System (INIS)

    Petty, S. M.; Armus, L.; Díaz-Santos, T.; Howell, J. H.; Surace, J. A.; Charmandaris, V.; Psychogyios, A.; Evans, A. S.; Stierwalt, S.; Floc’h, E. Le; Bridge, C.; Inami, H.

    2014-01-01

    We compare the morphologies of a sample of 20 luminous infrared galaxies (LIRGs) from the Great Observatories All-sky LIRG Survey (GOALS) in the FUV, B, I, and H bands, using the Gini (G) and M 20 parameters to quantitatively estimate the distribution and concentration of flux as a function of wavelength. Hubble Space Telescope (HST) images provide an average spatial resolution of ∼80 pc. While our LIRGs can be reliably classified as mergers across the entire range of wavelengths studied here, there is a clear shift toward more negative M 20 (more bulge-dominated) and a less significant decrease in G values at longer wavelengths. We find no correlation between the derived FUV G-M 20 parameters and the global measures of the IR to FUV flux ratio (IRX). Given the fine resolution in our HST data, this suggests either that the UV morphology and IRX are correlated on very small scales, or that the regions emitting the bulk of the IR emission emit almost no FUV light. We use our multi-wavelength data to simulate how merging LIRGs would appear from z∼0.5–3 in deep optical and near-infrared images such as the Hubble Ultra-Deep Field, and use these simulations to measure the G-M 20 at these redshifts. Our simulations indicate a noticeable decrease in G, which flattens at z⩾2 by as much as 40%, resulting in mis-classifying our LIRGs as disk-like, even in the rest-frame FUV. The higher redshift values of M 20 for the GOALS sources do not appear to change more than about 10% from the values at z∼0. The change in G-M 20 is caused by the surface brightness dimming of extended tidal features and asymmetries, and also the decreased spatial resolution which reduced the number of individual clumps identified. This effect, seen as early as z∼0.5, could easily lead to an underestimate of the number of merging galaxies at high-redshift in the rest-frame FUV.

    Full Text Available The article presents introduction prospects for rare and endangered plants of the Crimean flora. The target of research puts together types of the Crimean natural flora included to the global and regional protection documents; such plants grow in the N. V. Bagrov Botanical Garden of the Taurida Academy, V. I. Vernadsky Crimean Federal University, in Simferopol. The observations were conducted in 2010-2016. As a result of an integral assessment of plants decorative features, 34 promising and 20 highly decorative species have been marked for wide cultivation and introduction into planting of the Crimean foothill. The studied species are recommended for use in planting of various flowerbeds’ types as accent, dominant, shading, and auxiliary plants. Some 24 of the proposed types are heliophyte plants and are recommended for planting the solar sites; 10 types are suitable for half-shaded and shaded areas. In the wild, the majority of these plants are adapted to dry growing conditions; this improves their cultivation prospects in the arid areas.

  14. Numerical anomalies in the dentition of southern fur seals and sea lions (Pinnipedia: Otariidae

    Directory of Open Access Journals (Sweden)

    Carolina Loch

    2010-06-01

    Full Text Available Cases of dental agenesis, supernumerary teeth and dental losses are presented in three species of South American Otariids: Arctocephalus australis (Zimmermann, 1783, A. tropicalis (Gray, 1872 and Otaria flavescens (Shaw, 1800. For the first time, congenital and acquired dental anomalies were comparatively diagnosed in skull samples from southern Brazil and nearby areas. The skulls and mandibles were accessed in the scientific collection of mammals of the Federal University of Santa Catarina, southern Brazil. Agenesis was found only among maxillary post-canine teeth, especially the distal ones (PC/6, due to an evolutionary trend towards reduction of the number of post-canine teeth in this family. Maxillary and mandibular supernumerary teeth were found in A. australis and A. tropicalis, but their positioning is unrelated to cases regarding phylogenetic and evolutionary implications. Dental losses were found in all species and different stages of alveolar obliteration suggest that this process is common in Otariids and does not affect their survival. The investigation of congenital and acquired dental anomalies in pinnipeds can provide information on dental formula evolution in Pinnipeds and in the phylogenetic relationships among Carnivora.

  20. Genital morphology of the male South American fur seal (Arctocephalus australis and biological implications

    Directory of Open Access Journals (Sweden)

    Alex Sander D. Machado

    2012-12-01

    Full Text Available Male capacity for spreading genes to a great number of descendents and to determine population dynamics depend directly on the genital organs. Morphological studies in pinnipeds are scarce and the functional meaning of some characteristics has never been discussed. We hypothesized that Arctocephalus australis (A. australis shows morphophysiological adaptations in order to guarantee the perpetuation of the species in the unique annual mating season. Seven males, dead from natural causes, had their genital organs collected and fixed for morphological description. Some features differ from other described mammalian males and are closely related to the biology and reproductive cycle of this species, as the scrotal epidermis, absence of glandular portion in the ductus deferens and spermatogenic epithelium suggest a recrudescent testis period. The corona glandis exhibits a singular arrangement: its erectile border looks like a formation of petals and its association with the os penis gives a "lily-flower" form to this region. We propose the name margo petaliformis to this particular erectile border of the corona glandis because of its similarity to a flower corola. The male genital organs of A. australis show morphological features compatible with adaptation to environment requirements and reproductive efficiency.

    The authors lived for quite a long time in Wendland , the village of opponents of atomic energy at Gorleben. They regard the conflict on the issue of Gorleben and atomic energy as being located within the fundamental conflict existing between various ways of life: between the rather traditional region with the centralistic model of the atomic state and their hopes for decentralized ecological communities. They report on the practical development of this resistance and point out its forms of struggle which have to be proportionate to the atomic antagonist, friends and foes in the region as well as to their own requirements and objectives concerning an ecological and independent way of life.

  4. Evidence based medicine at medical school: a three week course on the basis of problem based learning [Erlernen evidenz-basierter Medizin in der medizinischen Ausbildung. Ein drei Wochen Blockkurs auf der Grundlage des problemorientierten Lernens

    Directory of Open Access Journals (Sweden)

    Kuhnigk, Olaf

    2007-11-01

    Full Text Available [english] Profound conceptual knowledge in evidence based medicine is required as basic competence for practising physicians. Therefore contents of courses in medical statistics have moved from mere biostatistical methods to practice oriented concepts like EbM. To train these competences a course for medical statistics was developed and implemented. In 2003 and 2004 a class of medical students (n=56 in a parallel problem based curriculum at Hamburg Medical School participated in their fifth semester at the three week problem based learning (PBL course "The scientific approach". Course quality and learning objectives were evaluated by questionnaire and exams. Results show that students feel to have reached the learning objectives, feel enabled to understand and to critically appraise relevant literature, and feel well prepared for their own scientific work. Course contents were judged from satisfying to good. The following items were rated very positively: learning objectives, clinical orientation of the course, integration of subjects, positive learning climate, and content and organization of the course. Exam results were above average. Positive evaluation and exam results recommend this course as blueprint for teaching and learning evidence based biostatistics in medical education. [german] Einleitung: Profundes konzeptionelles Wissen in der „Evidenzbasierten Medizin“ stellt heutzutage eine Basiskompetenz für klinisch tätige Ärzte dar. Als Konsequenz daraus entwickelten sich Lehrinhalte der studentischen Ausbildung in der Biomathematik von der reinen Lehre statistischer Methoden zu praxisorientierten Konzepten, wie dem der evidenzbasierten Medizin. Zur Vermittlung dieser Fähigkeiten wurde ein neues Blockkurskonzept unter modernen lerndidaktischen Erkenntnissen entwickelt und erprobt. Methode: Zwei Studienjahrgänge (n=56 des Modellstudiengangs Medizin der Universität Hamburg in Deutschland nahmen 2003 und 2004 im fünften Hochschulsemester an einem dreiwöchigen Blockkurs „Wissenschaftliches Arbeiten“ auf der lerndidaktischen Grundlage des problemorientierten Lernens teil. Kursqualität und Lernziele wurden mittels Fragebögen und Prüfungen evaluiert. Ergebnisse: Die Evaluationsergebnisse zeigten, dass die Studierenden aus eigener Sicht die definierten Lernziele erreicht haben: Sie fühlten sich in der Lage relevante Literatur zu verstehen und kritisch zu beurteilen. Darüber hinaus fühlten sie sich auf eigenes wissenschaftliches Arbeiten vorbereitet. Die einzelnen inhaltlichen Ausbildungsabschnitte wurden insgesamt als befriedigend bis gut beurteilt. Besonders positiv wurden die Lernziele, die klinische Ausrichtung, die Vernetzung der einzelnen Fächer, die positive Lehr- und Lernatmosphäre sowie die inhaltliche Ausgestaltung und organisatorische Struktur des Blockkurses evaluiert. Die Prüfungsergebnisse fielen überdurchschnittlich gut aus. Zusammenfassung: Die positiven Evalutions- und Prüfungsergebnisse sprechen dafür, dass der Kurs „Wissenschaftliches Arbeiten“ als „Blueprint“ für das Erlernen wesentlicher Fähig- und Fertigkeiten der evidenzbasierten Medizin für Studierende der Medizin dienen kann.

    Commercial hunting for the international trade in animal hides in the 20th century decimated many populations of aquatic wildlife in Amazonia. However, impacts varied significantly between different species and regions, depending upon hunting intensity, accessibility of habitat, and the inherent resilience of various species and their habitats. We investigated the differential responses of two Amazonian Mustelid species, the neotropical otter and giant otter, to commercial hunting pressure along the upper Rio Negro in Brazil, and examined historical factors that influenced spatial and temporal variation in commercial exploitation. We analyzed previously unanalyzed data from historical records of hide shipments to track changes in hide sales and prices for the two species in the late 20th century. We also gathered oral histories from older Baniwa people who had witnessed or participated in commercial otter hunting. These complimentary data sources reveal how intrinsic biological and social characteristics of the two otter species interacted with market forces and regional history. Whereas giant otter populations were driven to local or regional extinction during the late 20th century by commercial hunting, neotropical otters persisted. In recent decades, giant otter populations have returned to some parts of the upper Rio Negro, a development which local people welcome as part of a generalized recovery of the ecosystems in their territory as a result of the banning of animal pelt exports and indigenous land demarcation. This paper expands the scope of the field historical ecology and reflects on the role of local knowledge in biodiversity conservation.

    Full Text Available Body fat composition of the mink (Mustela vison, polecat (Mustela putorius, and the raccoon dog (Nyctereutes procyonoides was studied. The animals were fed a wet diet, supplemented with 5 % lard (LA or fish oil (FO for 5-6 months. At pelting, five animals per dietary group were sampled. Dietary levels of cetoleic (C22:1ω11, eicosapentaenoic (EPA, C20:5ω3, and docosahexaenoic (DHA, C22:6ω3 acids were 0.4, 0.3, and 0.5% in the fat of the LA diet, and 7.6, 4.2 and 4.3% in the FO diet, respectively. In the FO diet, EPA and DHA accumulated especially in the liver and heart, while cetoleic acid showed the highest affinity to the heart muscle and subcutaneous fat. The highest levels of EPA were found in raccoon dogs and polecats fed the FO diet. The mean EPA levels ranged from 6.7-9.3% in the liver fat and 7.2-8.0% in the heart muscle fat. In the mink, the corresponding values were 2.7% and 3.9%, respectively. DHA levels were the highest in the liver fat of the polecats, being 18.5% in the FO diet. In addition, the liver in raccoon dogs fed the FO diet (13.8% differed significantly from themink (9.4%. The differences in the accumulation of these long-chained marine fatty acids were apparently caused by species differences in the efficiency of their peroxisomal β-oxidation.

    Full Text Available Abstract Background Bacterial artificial chromosome (BAC libraries continue to be invaluable tools for the genomic analysis of complex organisms. Complemented by the newly and fast growing deep sequencing technologies, they provide an excellent source of information in genomics projects. Results Here, we report the construction and characterization of the CHORI-231 BAC library constructed from a Danish-farmed, male American mink (Neovison vison. The library contains approximately 165,888 clones with an average insert size of 170 kb, representing approximately 10-fold coverage. High-density filters, each consisting of 18,432 clones spotted in duplicate, have been produced for hybridization screening and are publicly available. Overgo probes derived from expressed sequence tags (ESTs, representing 21 candidate genes for traits important for the mink industry, were used to screen the BAC library. These included candidate genes for coat coloring, hair growth and length, coarseness, and some receptors potentially involved in viral diseases in mink. The extensive screening yielded positive results for 19 of these genes. Thirty-five clones corresponding to 19 genes were sequenced using 454 Roche, and large contigs (184 kb in average were assembled. Knowing the complete sequences of these candidate genes will enable confirmation of the association with a phenotype and the finding of causative mutations for the targeted phenotypes. Additionally, 1577 BAC clones were end sequenced; 2505 BAC end sequences (80% of BACs were obtained. An excess of 2 Mb has been analyzed, thus giving a snapshot of the mink genome. Conclusions The availability of the CHORI-321 American mink BAC library will aid in identification of genes and genomic regions of interest. We have demonstrated how the library can be used to identify specific genes of interest, develop genetic markers, and for BAC end sequencing and deep sequencing of selected clones. To our knowledge, this is the first report of 454 sequencing of selected BAC clones in mammals and re-assures the suitability of this technique for obtaining the sequence information of genes of interest in small genomics projects. The BAC end sequences described in this paper have been deposited in the GenBank data library [HN339419-HN341884, HN604664-HN604702]. The 454 produced contigs derived from selected clones are deposited with reference numbers [GenBank: JF288166-JF288183 &JF310744].

    This study aims to broaden the model-theoretic and empirical knowledge on energetic geographic development processes. Therefore household surveys collected in three rural and penalized regions of China. The main focus of this survey is on the energy ladder model, postulating a higher degree of energetic sustainability when the income of population is rising. This survey tries to verify the model or rather point out parameters which cause regular deviations from the model. The model must consider regional, cultural and political characteristics coevally. The core of this survey is a data collection in 180 households. Besides demographic and microeconomic information the data collection particularly provides data on energy consumption (energy mix, energy efficiency, future energy-preferences etc.). Last but not least the environmental impacts of energetic use are determined by the appraisals of the concerned households. The descriptive and correlative data analysis provides insightful data for the following four explored sectors (1) ''socio-economic situation'', (2) ''energy use'', (3) ''environmental awareness'' and (4) ''demanded support''. The analysis allows conclusions on three different levels: a. A highly sophisticated picture of the selected regions emerges, that is presented by a multiple analogy among each other. b. The overall data afford an overview of interactions between the essential parameters of the study: Those are energy use, energy efficiency, access to energy, environmental behavior, health and education. c. On the basis of those two levels the following modification of the model is devised: The peripheral location, the cultural situation and the interventions from government as well as from civil society are parameters that significantly codetermine the choice for energy sources in rural areas. The analysis of demanded support in the energy sector as well as the conclusions of the families on environmental awareness establishes the basis for a row of suggestions of the author. Those suggestions shall allow a more sustainable energy use in the study areas. More participation, respectively a stronger comprehension of the rural population into the planning and development of energy supply systems is a very essential concern of the households. As an eminently sustainable technology the production of biogas is suggested within closed energy-nutrient loops (Integration of stables, toilets, green houses etc.). This can only be achieved by an intensive assistance.

    The worrisome issues resulting from the civilian use of nuclear energy are subjected to a scientific analysis in R. Dautray's report. They include: the risks of accidents and radiation, the question of nuclear wastes (in particular, plutonium and actinides), and the dangers of atomic weapons proliferating or nuclear plants being menaced by terrorists. The nuclear industry will not be able to go on unless it comes up with solutions acceptable to citizens. Even if the decision were made to put an end to nuclear power plants, a solution would have to be found for putting an end to the aftereffects. According to this report, it is indispensable to have a base of knowledge accepted by all if we are to weigh various proposals and make decisions. It contends that the program under way in France since the 1991 Bataille Act should, for the 2006 deadline, set as its main objective to define 'a general criterion of protection and confidence of the concerned workers and populations, a criterion worked out by their elected representatives, thus by public authorities'. The report's author has proposed points for drawing up such a criterion. (author)

Three of the 23 patients who had a three year follow-up had chronic renal changes, 10 had renal stones. As blunt renal trauma can be the cause of renal hypertension a longterm follow-up is necessary in ESWL patients, particularly if there was renal bleeding after treatment. Further studies are needed to determine the exact risk of renal hypertension after ESWL. (orig.)

    In this study, compound FTBI (3-(2-furyl)-10-(2-phenylethyl)[1,2,4]triazino[4,3-a]benzimidazol-4(10H)-one) was selected from a small library of triazinobenzimidazole derivatives as a potent A(2A) adenosine receptor (AR) antagonist and tested for its neuroprotective effects against two different kinds of dopaminergic neurotoxins, 1-methyl-4-phenylpyridinium (MPP+) and methamphetamine (METH), in rat PC12 and in human neuroblastoma SH-SY5Y cell lines. FTBI, in a concentration range corresponding to its affinity for A(2A) AR subtype, significantly increased the number of viable PC12 cells after their exposure to METH and, to a similar extent, to MPP+, as demonstrated in both trypan blue exclusion assay and in cytological staining. These neuroprotective effects were also observed with a classical A(2A) AR antagonist, ZM241385, and appeared to be completely counteracted by the AR agonist, NECA, supporting A(2A) ARs are directly involved in FTBI-mediated effects. Similarly, in human SH-SY5Y cells, FTBI was able to prevent cell toxicity induced by MPP+ and METH, showing that this A(2A) AR antagonist has a neuroprotective effect independently by the specific cell model. Altogether these results demonstrate that the A(2A) AR blockade mediates cell protection against neurotoxicity induced by dopaminergic neurotoxins in dopamine containing cells, supporting the potential use of A(2A) AR antagonists in dopaminergic degenerative diseases including Parkinson's disease.

    Full Text Available Male capacity for spreading genes to a great number of descendents and to determine population dynamics depend directly on the genital organs. Morphological studies in pinnipeds are scarce and the functional meaning of some characteristics has never been discussed. We hypothesized that Arctocephalus australis (A. australis shows morphophysiological adaptations in order to guarantee the perpetuation of the species in the unique annual mating season. Seven males, dead from natural causes, had their genital organs collected and fixed for morphological description. Some features differ from other described mammalian males and are closely related to the biology and reproductive cycle of this species, as the scrotal epidermis, absence of glandular portion in the ductus deferens and spermatogenic epithelium suggest a recrudescent testis period. The corona glandis exhibits a singular arrangement: its erectile border looks like a formation of petals and its association with the os penis gives a "lily-flower" form to this region. We propose the name margo petaliformis to this particular erectile border of the corona glandis because of its similarity to a flower corola. The male genital organs of A. australis show morphological features compatible with adaptation to environment requirements and reproductive efficiency.A capacidade do macho de espalhar seus genes a um grande número de descendentes e determinar a dinâmica populacional depende diretamente dos seus órgãos genitais. Estudos morfológicos em pinípedes são escassos e o significado funcional de algumas de suas características ecológicas ainda foi pouco discutido. Nossa hipótese é que Arctocephalus australis (A. australis apresenta adaptações morfofisiológicas em seus órgãos genitais capazes de interagir com o meio e garantir a perpetuação da espécie que apresenta apenas uma época de acasalamento que ocorre uma vez a cada ano. Sete A. australis machos, mortos recentes por causas naturais, tiveram seus órgãos genitais coletados e fixados para a descrição macro, micro e ultraestrutural. Algumas características diferem de outros machos já descritos e estão intimamente relacionados com a biologia e ciclo reprodutivo da espécie, dentre elas podemos citar a alta queratinização da epiderme escrotal que pode se relacionar com as rotineiras lesões por atrito desta região nas pedras; a ausência da porção glandular do ducto deferente aqui descrita pela primeira vez, o epitélio espermatogênico sugere um período de testículo recrudescente. A glande apresenta um arranjo singular: a coroa da glande apresenta porção lateral de tecido esponjoso que são bordas livres com capacidade de intumescencia. O osso peniano se encontra no centro destas bordas e representa a extremidade mais distal do penis, levando consigo o óstio uretral externo. As bordas associadas ao osso peniano, dão uma forma de "Flor de lírio" a esta região. Utilizamos o nome margo petaliformis a margem erétil liliforme a particular morfologia da glande, pela sua semelhança a uma corola de flor. Os órgãos genitais masculinos de A. australis mostram características morfológicas compatíveis com uma adaptação aos requisitos ambientais e de eficiência reprodutiva.

    To evaluate the efficacy of flexible ureterscopy (fURS) and extracorporal shockwave lithotripsy (SWL) in the treatment of urolithiasis, complemented by a subgroup analysis of lower pole calyx. Retrospective analysis of patients treated by fURS or SWL was performed by independent variables such as gender, age, nephrolith size, double-J stent (DJ stent) and stone localisation. Out of 326 patients, 165 were treated by SWL and 161 by fURS. Complete stone removal was achieved by fURS in 83.2% and by SWL in 43.0% (p auxillary DJ stent was performed more often preoperative before fURS. The subgroup analysis of lower pole calyx confirmed these evaluations. Complete stone-free removal was almost 8 times higher after fURS compared to SWL. The efficacy of fURS in treatment of urolithiasis is substantially higher than the efficacy of SWL. © 2015 S. Karger AG, Basel.

    This on-the-spot report gives an account of one day at the reactor operator's training centre of Kraftwerks-Simulator Gesellschaft in Essen, West-Germany. Heavy criticism is raised by the reporter who found out that none of the four simulators' computer programs includes the scenarios of accidents that may lead to severe reactor core damage. The conclusion drawn from this fact is that the West-German reactor operating personnel is just as incapable of managing a severe accident as their colleagues in Chernobyl. (DG).

    At Ore Treatment Unit (UTM, in Portuguese) situated in Pocos de Caldas, MG, there is a deposit of about 40 tons radioactive waste produced decades ago from Santo Amaro deactivated plant (SAP) and then from NUCLEMON that processed monazite sands to extract rare earth elements. This waste contains uranium and thorium and it is stored in six hangars. This study aims to analyze the dose rates in the hangars from 2002 to 2012. Annually, two samples were obtained, for a total of 24 samples. The results showed the highest doses rates at UTM, ranging from 0.5 to 409.8 μSv h{sup -}'1 for the total set of samples. The averages extended from 0.96 μSv h{sup -1} in hangar C-02 up to 282.64 μSv h{sup -1} in hangar C-05. Considering each hangar separately, the results were as follows: hangar C-01 average 30.34 μSv h{sup -1}, ranging from 6.2 to 71.7 μSv h{sup -1}; hangar C-02 average 0.96 μSv h{sup -1} (min-max 0.5 to 2.51 μSv h{sup -1}); hangar C-05 average 282.64 μSv h{sup -1} (min-max 3.7 to 409.8 μSv h{sup -1}); hangar C-06 average 188.92 μSv h{sup -1} (min-max 1.85 to 338.0 μSv h{sup -1}); hangar C-07, average 172.05 μSv h{sup -1} (min-max 1.95 to 283.0 μSv h{sup -1}) and hangar C-09, average 122.59 μSv h{sup -1} (min-max 1.11 to 277.0 μSv h{sup -1}). ANOVA test indicated that the dose rates averages in the six hangars are different (F{sub calc} of 70.90 higher F{sub crit} of 2.28), and the Tukey test allowed to group the hangars in the following sequence: C-05> C-06 = C-07> C-09> C-01 = C-02.

    2010-01-01

    Automated User's Training Operations Facility Utilization Request (AutoFUR) is prototype software that administers a Web-based system for requesting and allocating facilities and equipment for astronaut-training classes in conjunction with scheduling the classes. AutoFUR also has potential for similar use in such applications as scheduling flight-simulation equipment and instructors in commercial airplane-pilot training, managing preventive- maintenance facilities, and scheduling operating rooms, doctors, nurses, and medical equipment for surgery. Whereas requesting and allocation of facilities was previously a manual process that entailed examination of documents (including paper drawings) from different sources, AutoFUR partly automates the process and makes all of the relevant information available via the requester s computer. By use of AutoFUR, an instructor can fill out a facility-utilization request (FUR) form on line, consult the applicable flight manifest(s) to determine what equipment is needed and where it should be placed in the training facility, reserve the corresponding hardware listed in a training-hardware inventory database, search for alternative hardware if necessary, submit the FUR for processing, and cause paper forms to be printed. Auto-FUR also maintains a searchable archive of prior FURs.

Sympatric Galapagos fur seals (Arctocephalus galapagoensis and sea lions (Zalophus wollebaeki share similar geographic habitats and potentially compete. We studied their foraging niche overlap at Cabo Douglas, Fernandina Island from simultaneously collected dive and movement data to examine spatial and temporal inter- and intra-specific competition. Sea lions exhibited 3 foraging strategies (shallow, intermediate and deep indicating intra-specific competition. Fur seals exhibited one foraging strategy, diving predominantly at night, between 0-80 m depth and mostly at 19-22 h. Most sea lion dives also occurred at night (63%, between 0-40 m, within fur seals' diving depth range. 34% of sea lions night dives occurred at 19-22 h, when fur seals dived the most, but most of them occurred at dawn and dusk, when fur seals exhibited the least amount of dives. Fur seals and sea lions foraging behavior overlapped at 19 and 21 h between 0-30 m depths. Sea lions from the deep diving strategy exhibited the greatest foraging overlap with fur seals, in time (19 h, depth during overlapping time (21-24 m, and foraging range (37.7%. Fur seals foraging range was larger. Cabo Douglas northwest coastal area, region of highest diving density, is a foraging "hot spot" for both species. Fur seals and sea lions foraging niche overlap occurred, but segregation also occurred; fur seals primarily dived at night, while sea lions exhibited night and day diving. Both species exploited depths and areas exclusive to their species. Niche breadth generally increases with environmental uncertainty and decreased productivity. Potential competition between these species could be greater during

  16. Molecular evidence for a diverse green algal community growing in the hair of sloths and a specific association with Trichophilus welckeri (Chlorophyta, Ulvophyceae

    Full Text Available Abstract Background Sloths are slow-moving arboreal mammals inhabiting tropical rainforests in Central and South America. The six living species of sloths are occasionally reported to display a greenish discoloration of their pelage. Trichophilus welckeri, a green algal species first described more than a century ago, is widely believed to discolor the animals fur and provide the sloth with effective camouflage. However, this phenomenon has not been explored in any detail and there is little evidence to substantiate this widely held opinion. Results Here we investigate the genetic diversity of the eukaryotic community present in fur of all six extant species of sloth. Analysis of 71 sloth hair samples yielding 426 partial 18S rRNA gene sequences demonstrates a diverse eukaryotic microbial assemblage. Phylogenetic analysis reveals that sloth fur hosts a number of green algal species and suggests that acquisition of these organisms from the surrounding rainforest plays an important role in the discoloration of sloth fur. However, an alga corresponding to the morphological description of Trichophilus welckeri was found to be frequent and abundant on sloth fur. Phylogenetic analysis demonstrated the retention of this alga on the fur of sloths independent of geographic location. Conclusions These results demonstrate a unique diverse microbial eukaryotic community in the fur of sloths from Central and South America. Our analysis streghtens the case for symbiosis between sloths and Trichophilus welckeri.

    To compare the outcomes of flexible ureterorenoscopy (F-URS) and mini-percutaneous nephrolithotomy (mini-PNL) in the treatment of lower calyceal stones smaller than 2 cm. Patients who underwent F-URS and mini-PNL for the treatment of lower calyceal stones smaller than 2 cm between March 2009 and December 2014 were retrospectively evaluated. Ninety-four patients were divided into two groups by treatment modality: F-URS (Group 1: 63 patients) and mini-PNL (Group 2: 31 patients). All patients were preoperatively diagnosed with intravenous pyelography or computed tomography. Success rates for F-URS and mini-PNL at postoperative first month were 85.7% and 90.3%, respectively. Operation time, fluoroscopy time, and hospitalization time for F-URS and mini-PNL patients were 44.40 min, 2.9 min, 22.4 h, and 91.9 min, 6.4 min, and 63.8 h, respectively. All three parameters were significantly shorter among the F-URS group (p PNL group (0.39 mg/dL vs. 1.15 mg/dL, p = 0.001). A comparison of complications according to the Clavien classification demonstrated significant differences between the groups (p = 0.001). More patients in the F-URS groups require antibiotics due to urinary tract infection, and more patients in the mini-PNL group required ureteral double J catheter insertion under general anesthesia. Although both F-URS and mini-PNL have similar success rates for the treatment of lower calyceal stones, F-URS appears to be more favorable due to shorter fluoroscopy and hospitalization times; and lower hemoglobin drops. Multicenter and studies using higher patient volumes are needed to confirm these findings.

    Full Text Available The proposed paper aims to provide new subsidies to the definition of Functional Urban Regions (FURs, testing the viability of a variable not yet explored in Brazil: commuting flows. Thus, a case study is developed in the state of São Paulo. With the application of spatial statistics techniques on travel data and construction of Box Maps, the results were compared with the limits of the official FURs. The obtained results reflect the interrelations among municipalities within the FURs, since attractive areas appear next to peripheral areas and highlight important regional centers, which can be the core of conurbations in the future.

    Total mercury (Hg) concentrations were measured in the fur, brain and liver of wild mink (Mustela vison) and river otters (Lontra canadensis) collected from eastern and Atlantic Canada. Total Hg concentrations in fur were strongly correlated with levels in the brain and liver. There was no difference in tissue concentrations between male and female mink; however, female otters had significantly higher fur, brain and liver Hg levels than males. Similarly, there was not a significant relationship between Hg concentration and age of mink, whereas in otters, Hg concentrations in all three tissues decreased significantly with age. In both species, only a very small percentage of the variability in Hg concentration was explained by age. After adjusting the data for site-to-site differences in Hg levels, Hg concentrations in the fur of mink infected by the parasite, Dioctophyma renale, were found to be significantly higher than Hg levels in uninfected mink.

    Colostrum-deprived neonatal Northern fur seal pups (Callorhinus ursinus) were exposed to San Miguel sea lion virus type 5 (SMSV-5) by feeding them fish (Girella nigricans) infected with virus or fish infected with both the sea lion lung worm larvae (Parafilaroides decorus) and virus. Virus infection was demonstrated in 8 of 9 pups, and 1 of these developed a vesicular lesion on the flipper. In this sequence, P decorus larvae exposed to SMSV-5 were fed to G nigricans held at 15 C in a salt water aquarium; 32 days later, these fish were killed, then fed to the fur seal pups. The vesicle developed 22 days subsequent to this and SMSV-5 was reisolated from the lesion. The SMSV-5 was shown to persist for at least 23 days in infected neonatal fur seals. Attempts to establish P decorus infection in Northern fur seal pups were apparently unsuccessful.

    Total mercury (Hg) concentrations were measured in the fur, brain and liver of wild mink (Mustela vison) and river otters (Lontra canadensis) collected from eastern and Atlantic Canada. Total Hg concentrations in fur were strongly correlated with levels in the brain and liver. There was no difference in tissue concentrations between male and female mink; however, female otters had significantly higher fur, brain and liver Hg levels than males. Similarly, there was not a significant relationship between Hg concentration and age of mink, whereas in otters, Hg concentrations in all three tissues decreased significantly with age. In both species, only a very small percentage of the variability in Hg concentration was explained by age. After adjusting the data for site-to-site differences in Hg levels, Hg concentrations in the fur of mink infected by the parasite, Dioctophyma renale, were found to be significantly higher than Hg levels in uninfected mink. - Mercury (Hg) concentrations in liver, brain and fur are correlated in mink (Mustela vison) and otters (Lontra canadensis), allowing the use of fur as an indicator of internal tissue concentrations.

    Administered by an oral route, Furosemide (FUR), a diuretic used in several edematous states and hypertension, presents bioavailability problems, reported as a consequence of an erratic gastrointestinal absorption due to various existing polymorphic forms and low and pH-dependent solubility. A mucoadhesive sublingual fast-dissolving FUR based film has been developed and evaluated in order to optimize the bioavailability of FUR by increasing solubility and guaranteeing a good dissolution reproducibility. The Differential Scanning Calorimetry (DSC) analyses confirmed that the film prepared using the solvent casting method entrapped FUR in the amorphous state. As a solid dispersion, FUR increases its solubility up to 28.36 mg/mL. Drug content, thickness, and weight uniformity of film were also evaluated. The measured Young's Modulus, yield strength, and relative elongation of break percentage (EB%) allowed for the classification of the drug-loaded film as an elastomer. Mucoadhesive strength tests showed that the force to detach film from mucosa grew exponentially with increasing contact time up to 7667 N/m². FUR was quickly discharged from the film following a trend well fitted with the Weibull kinetic model. When applied on sublingual mucosa, the new formulation produced a massive drug flux in the systemic compartment. Overall, the proposed sublingual film enhances drug solubility and absorption, allowing for the prediction of a rapid onset of action and reproducible bioavailability in its clinical application.

    Full Text Available In diesem Beitrag wird Globalisierung als Prozess der Umstellung von Bezugssystemen des Denkens und Handelns von "Staat" auf "Welt" konzipiert. Von der klassischen Definition des Nationalstaates ausgehend, werden zuerst drei staatszentrierte Bezugssysteme (Rechtsstaat, Sozialstaat, Territorialstaat skizziert. Im zweiten Schritt werden globale Bezugssysteme (Welt als einheitlicher Markt, als Gefüge von Herrschaftsgebilden, als Konglomerat von Kulturen umrissen. Die Argumentation läuft darauf hinaus, zu zeigen, dass es sich bei diesen Konzeptionen keineswegs um geschlossene und harmonische Gesellschafts- und Weltbilder handelt; vielmehr enthält jedes der sechs Bezugsysteme spezifische Spannungs- und Konfliktlinien, aus denen sich ihre jeweilige Dynamik speist. Im dritten Schritt werden Prozesse der Umstellung der Bezugssysteme in Richtung Globalität auf drei Ebenen analysiert: auf der Ebene umfassender historischer Prozesse, auf der Ebene staatlichen Handelns und auf der Ebene individueller Akteure.

    In "Die Leiden des jungen Werther" finden sich drei Arten von Naturbeschreibung : Naturbeschreibung mit Naturgefühl, Beschreibung der Natur als locus amoenus und Landschaftsbeschreibung. Indem Werther immer innerlicher wird, wird die Natur als Landschaft betrachtet, weil "sich die Landschaft mit einem einsamen inneren Zustand verknüpft" (Kojin Karatani). Nach S. Freud beginnt das Innen "erst mit der Ausbilding einer abstrakten Denksprache" (Totem und Tabu) zu existieren. Mit Freud läßt sich b...
