Eurycomanone and eurycomanol from Eurycoma longifolia Jack as regulators of signaling pathways involved in proliferation, cell death and inflammation.  

PubMed

Eurycomanone and eurycomanol are two quassinoids from the roots of Eurycoma longifolia Jack. The aim of this study was to assess the bioactivity of these compounds in Jurkat and K562 human leukemia cell models compared to peripheral blood mononuclear cells from healthy donors. Both eurycomanone and eurycomanol inhibited Jurkat and K562 cell viability and proliferation without affecting healthy cells. Interestingly, eurycomanone inhibited NF-?B signaling through inhibition of I?B? phosphorylation and upstream mitogen activated protein kinase (MAPK) signaling, but not eurycomanol. In conclusion, both quassinoids present differential toxicity towards leukemia cells, and the presence of the ?,?-unsaturated ketone in eurycomanone could be prerequisite for the NF-?B inhibition.

NF-?B inhibitors from Eurycoma longifolia.  

PubMed

The roots of Eurycoma longifolia have been used in many countries of Southeast Asia to alleviate various diseases including malaria, dysentery, sexual insufficiency, and rheumatism. Although numerous studies have reported the pharmacological properties of E. longifolia, the mode of action of the anti-inflammatory activity has not been elucidated. Bioguided isolation of NF-?B inhibitors using an NF-?B-driven luciferase reporter gene assay led to the identification of a new quassinoid, eurycomalide C (1), together with 27 known compounds including 11 quassinoids (2-12), six alkaloids (13-18), two coumarins (19, 20), a squalene derivative (21), a triterpenoid (22), and six phenolic compounds (23-28) from the extract of E. longifolia. Evaluation of the biological activity revealed that C19-type and C20-type quassinoids, ?-carboline, and canthin-6-one alkaloids are potent NF-?B inhibitors, with IC50 values in the low micromolar range, while C18-type quassinoids, phenolic compounds, coumarins, the squalene derivative, and the triterpenoid turned out to be inactive when tested at a concentration of 30 ?M. Eurycomalactone (2), 14,15?-dihydroklaieanone (7), and 13,21-dehydroeurycomanone (10) were identified as potent NF-?B inhibitors with IC50 values of less than 1 ?M. PMID:24467387

Genetic Diversity of Eurycoma longifolia Inferred from Single Nucleotide Polymorphisms1[w  

PubMed Central

Eurycoma longifolia Jack. is a treelet that grows in the forests of Southeast Asia and is widely used throughout the region because of its reported medicinal properties. Widespread harvesting of wild-grown trees has led to rapid thinning of natural populations, causing a potential decrease in genetic diversity among E. longifolia. Suitable genetic markers would be very useful for propagation and breeding programs to support conservation of this species, although no such markers currently exist. To meet this need, we have applied a genome complexity reduction strategy to identify a series of single nucleotide polymorphisms (SNPs) within the genomes of several E. longifolia accessions. We have found that the occurrence of these SNPs reflects the geographic origins of individual plants and can distinguish different natural populations. This work demonstrates the rapid development of molecular genetic markers in species for which little or no genomic sequence information is available. The SNP markers that we have developed in this study will also be useful for identifying genetic fingerprints that correlate with other properties of E. longifolia, such as high regenerability or the appearance of bioactive metabolites.

In vitro anti-tumor promoting and anti-parasitic activities of the quassinoids from Eurycoma longifolia, a medicinal plant in Southeast Asia.  

PubMed

Some quassinoids (1-6) isolated previously as plant growth inhibitors from the leaves of Eurycoma longifolia Jack. (Simaroubaceae) were subjected to in vitro tests on anti-tumor promoting, antischistosomal and plasmodicidal activities. The most active compound for inhibition of tumor promoter-induced Epstein-Barr virus activation (anti-tumor promotion) was 14,15beta-dihydroxyklaineanone (5, IC(50) = 5 microM). Longilactone (1) gave significant antischistosomal effect at a concentration of 200 microg/ml. 11-Dehydroklaineanone (3) and 15beta-O-acetyl-14-hydroxyklaineanone (6) showed potent plasmodicidal activity (IC(50) = 2 microg/ml). Thus it was suggested that E. longifolia possesses high medicinal values due to the occurrence of a variety of quassinoids. PMID:12169407

This study was conducted for the assessment of the antimicrobial activities of different solvents extracted samples from the aerial parts of Mentha longifolia against ten microbial species through the disc diffusion assay using two different concentrations of 1 and 2 mg disc1. All extracts from Mentha longifolia showed different ranges of antimicrobial activities. Butanol and ethyl acetate fractions showed inhibitory activities against all microbial species. Methanol fraction showed inhibitory effects against all the tested microbial species except Salmonella typhi. Salmonella typhi was also not controlled by methanol, petroleum ether and dichloromethane extracted samples. The most susceptible gram positive bacteria was Bacillus atropheus and Bacillus subtilis and were inhibited by all extracts and Staphylococus aureus was least susceptible among gram positive bacteria. Klebsiella pneumoniae was the most susceptible gram negative bacterium and Salmonella typhi was highly resistant among the gram negative bacteria. Erwinia carotovora and Agrobacterium tumefaciene were susceptible to all fractions. All fractions showed antifungal activities against Candida albicans except water extracted samples. PMID:25015464

Pharmacological and therapeutic effects of Mentha Longifolia L. and its main constituent, menthol  

PubMed Central

Mentha longifolia (wild mint) is a popular folk remedy. Some parts of this plant have been used in traditional medicine of Iran and other countries. Many studies have shown various pharmacological and therapeutic effects of the plant. Our aim in preparing this study was to review the traditional uses of M. longifolia together with the pharmacological and therapeutic effects of its entire extract and major compounds. Mentha longifolia is an herb with a wide range of pharmacological properties such as antimicrobial, gastrointestinal, and nervous system effects. Pulegone is the main compound of the plant responsible for most of its pharmacological effects followed by menthone, isomenthone, menthol, 1, 8-cineole, borneol, and piperitenone. Moreover, the plant may dose-dependently exert toxic effects in different systems of the body. Based on the review of various studies, it can be concluded that M. longifolia is a potential natural source for the development of new drugs. However, further studies are required to determine the precise quality and safety of the plant to be used by clinicians.

Salt tolerance traits increase the invasive success of Acacia longifolia in Portuguese coastal dunes.  

PubMed

Salt tolerance of two co-occurring legumes in coastal areas of Portugal, a native species--Ulex europaeus, and an invasive species--Acacia longifolia, was evaluated in relation to plant growth, ion content and antioxidant enzyme activities. Plants were submitted to four concentrations of NaCl (0, 50, 100 and 200 mM) for three months, under controlled conditions. The results showed that NaCl affects the growth of both species in different ways. Salt stress significantly reduced the plant height and the dry weight in Acacia longifolia whereas in U. europaeus the effect was not significant. Under salt stress, the root:shoot ratio (W(R):W(S)) and root mass ratio (W(R):W(RS)) increased as a result of increasing salinity in A. longifolia but the same was not observed in U. europaeus. In addition, salt stress caused a significant accumulation of Na+, especially in U. europaeus, and a decrease in K+ content and K+/Na+ ratio. The activities of antioxidant enzymes were higher in A. longifolia compared to U. europaeus. In A. longifolia, catalase (CAT, EC 1.11.1.6) and glutathione reductase (GR, EC 1.6.4.2.) activities increased significantly, while ascorbate peroxidase (APX, EC 1.11.1.11) and peroxidase (POX, EC 1.11.1.7) activities remained unchanged in comparison with the control. In U. europaeus, NaCl concentration significantly reduced APX activity but did not significantly affect CAT, GR and POX activities. Our results suggest that the invasive species copes better with salinity stress in part due to a higher rates of CAT and GR activities and a higher K+/Na+ ratio, which may represent an additional advantage when competing with native species in co-occurring salty habitats.

Clerodane diterpenes isolated from Polyalthia longifolia induce apoptosis in human leukemia HL-60 cells.  

PubMed

Polyalthia is a versatile genus of shrubs and trees found in tropic and sub-tropic regions. In this study, three clerodane diterpenes, kolavenic acid (1), polyalthialdoic acid (2), and 16?-hydroxy-cleroda-3,13(14)Z-dien-15,16-olide (3) isolated from Polyalthia longifolia leaves were evaluated for their apoptotic potential against human leukemia HL-60 cells. Compounds 2 and 3 inhibited cell proliferation with IC?? values of 21.8 and 13.7 ?M, respectively. Morphological changes and DNA fragmentation analysis indicated that these diterpenes induce apoptotic cell death in the HL-60 cells. Our results revealed the importance of P. longifolia as a chemopreventive medicinal plant. PMID:24088522

Multilevel Dyson Brownian motions via Jack polynomials  

E-print Network

We introduce multilevel versions of Dyson Brownian motions of arbitrary parameter $\\beta>0$, generalizing the interlacing reflected Brownian motions of Warren for $\\beta=2$. Such processes unify $\\beta$ corners processes and Dyson Brownian motions in a single object. Our approach is based on the approximation by certain multilevel discrete Markov chains of independent interest, which are defined by means of Jack symmetric polynomials. In particular, this approach allows to show that the levels in a multilevel Dyson Brownian motion are intertwined (at least for $\\beta\\ge 1$) and to give the corresponding link explicitly.

Jack-up leveling barge for shallow water rigs  

SciTech Connect

Generally, the only alternative to a shell pad is a shallow water jack-up or a submersible rig. And in some instances, it is impractical to tow these mobile rigs to the location because of the necessary dredging. A possible solution to this problem, devised by Chain Jacks, Inc., is a jack-up leveling barge that extends its legs and pads to the bottom in waters ranging to 35 ft deep, then ballasts down to a depth of 10 ft or so below the surface. The barge-mounted rigs move over the leveling barges, ballast down and start rigging up. At this point, the leveling barge de-ballasts to minimize the load on the legs and mats. Chain Jack says the concept will enable barge mounted rigs to drill in waters ranging from 25 to 35 ft, and the cost will be considerably less than that of jack-ups or submersibles.

Advanced jack up rig breaking U.S. construction drought  

SciTech Connect

A new heavy duty jack up, due in mid-1998, will be able to simultaneously drill and produce wells in harsher environments and deeper water than current jack ups in the worldwide fleet. Rowan Cos. Inc.`s Gorilla V is the only mobile offshore drilling unit (MODU) currently under construction in the US. Two more enhanced Gorilla design rigs are planned before the year 2000. The enhanced Gorilla class jack up represents the most technologically advanced jack up unit constructed to date. The rigs are structurally designed to meet year-round weather challenges in the harshest geographical environments. Rising demand for drilling rigs, coupled with a dwindling fleet, is generating supply shortages around the world, particularly at the high-specification end of the market. Even increasing the historical retirement age from 20 to 25 years, rig attrition continues at a level of about 18 rigs per year. Apart from the jack up market per se, however, Rowan`s strategy in designing and building enhanced Gorillas is to improve existing jack up drilling technology and offer the versatility to operate as a drilling unit, a mobile production unit, or both simultaneously in either open water locations or alongside existing platforms. The paper discusses the market for these heavy jack-ups, the use of one on the Cohasset project in Nova Scotia, the Gorilla V and enhanced Gorillas, geographical range of use, and MOPU economics.

Cytogeography of essential oil chemotypes of Eremophila longifolia F. Muell (Scrophulariaceae).  

PubMed

Previous studies have demonstrated that the widely distributed desert plant Eremophila longifolia has at least six geographically defined essential oil chemotypes. The focus of the present study is to extend and enhance information concerning known chemotypes and to investigate the involvement of cell nuclei ploidy in this variation. Forty field collected specimens of E. longifolia were taken from most of the mainland states of Australia then subjected to hydrodistillation to produce essential oils, which were then chemically characterised. Ploidy was determined using relative fluorescence of cell nuclei stained with propidium iodide, measured in a flow cytometer. Using principal component analysis (PCA), at least three essential oil chemotypes, in addition to the six already described, were identified in the present study. Previously described high yielding essential oil chemotypes were also characterised in terms of diploidy. For the first time diploid populations were identified in New South Wales, correlating with high yielding isomenthone/menthone and karahanaenone chemotypes. Furthermore, the separate diploid population previously described from Western Australia was demonstrated to be the safrole/methyl eugenol type, which is restricted to a small geographic range in far north-west Western Australia (Murchison District). All other chemotypes were shown to be tetraploid, including apparently randomly emerging individuals, representative of chemotypes producing low yields of isomenthone/menthone and karahanaenone similar in composition to the high yielding diploid types.

Molecular evolution at the self-incompatibility locus of Physalis longifolia (Solanaceae).  

PubMed

The simple codominant expression of the alleles at the self-incompatibility locus ( S) of Solanaceae and their extraordinary spectrum of sequence diversity present an ideal case for understanding the molecular forces that shape the sequence polymorphism of genes involved in recognition reactions. Here, with unprecedented conspecific sequences of 33 Physalis longifolia S alleles, including 27 of their single introns, the tempo-spatial nucleotide substitution patterns were first detailed for the S locus and analyzed in genealogical time scales. Three major genealogical clades of the 33 P. longifolia S alleles were used to divide the genealogical time into the within-clade and the between-clade periods. During the within-clade period, the average nonsynonymous substitution rate was 50% higher than the intron substitution rate but the opposite trend emerged for the between-clade period. A new and simple method developed here was utilized to estimate the selection intensity in the coding regions. The magnitudes and the distribution of these estimates, in conjunction with the spatial substitution pattern among closely related S sequences, revealed an initial short-term action of strong positive selection and a continuous but weaker action of negative selection brought by functional/structural constraints on the S alleles. The two modes of selection can significantly modify the branch lengths of an S genealogy and may be ubiquitous to recognition systems. PMID:12029360

What does population structure analysis reveal about the Pterostylis longifolia complex (Orchidaceae)?  

PubMed Central

Morphologically similar groups of species are common and pose significant challenges for taxonomists. Differences in approaches to classifying unique species can result in some species being overlooked, whereas others are wrongly conserved. The genetic diversity and population structure of the Pterostylis longifolia complex (Orchidaceae) in Tasmania was investigated to determine if four species, and potential hybrids, could be distinguished through genomic AFLP and chloroplast restriction-fragment-length polymorphism (RFLP) markers. Analysis of molecular variance (AMOVA) results indicated that little genetic variation was present among taxa, whereas PCoA analyses revealed genetic variation at a regional scale irrespective of taxa. Population genetic structure analyses identified three clusters that correspond to regional genetic and single taxon-specific phenotypic variation. The results from this study suggest that “longifolia” species have persisted throughout the last glacial maximum in Tasmania and that the complex may be best treated as a single taxon with several morphotypes. These results could have serious evolutionary and conservation implications as taxonomic changes could result in the instatement of a single, widespread taxon in which rarer morphotypes are not protected.

Evaluation of the Genotoxic Potential against H2O2-Radical-Mediated DNA Damage and Acute Oral Toxicity of Standardized Extract of Polyalthia longifolia Leaf  

PubMed Central

Medicinal plants have been used in medicoculturally diverse countries around the world, where it is a part of a time-honoured tradition that is respected even today. Polyalthia longifolia leaf extract has been previously reported as an efficient antioxidant in vitro. Hence, the genotoxic effects of P. longifolia leaf were investigated by using plasmid relation, comet, and Allium cepa assay. In the presence of???OH radicals, the DNA in supercoil was start nicked into open circular form, which is the product of the single-stranded cleavage of supercoil DNA and quantified as fragmented separate bands on agarose gel in plasmid relation assay. In the plasmid relation and comet assay, the P. longifolia leaf extract exhibited strong inhibitory effects against H2O2-mediated DNA damage. A dose-dependent increase of chromosome aberrations was also observed in the Allium cepa assay. The abnormalities scored were stickiness, c-mitosis, bridges, and vagrant chromosomes. Micronucleated cells were also observed at the interphase. The results of Allium cepa assay confirmed that the methanol extracts of P. longifolia exerted no significant genotoxic or mitodepressive effects at 100??g/mL. Thus, this study demonstrated that P. longifolia leaf extract has a beneficial effect against oxidative DNA damage. This experiment is the first report for the protective effect of P. longifolia on DNA damage-induced by hydroxyl radicals. Additionally in acute oral toxicity study, female rats were treated at 5000?mg/kg body weight of P. longifolia leaf extract and observed for signs of toxicity for 14 days. P. longifolia leaf extract did not produce any treatment-related toxic effects in rats. PMID:23878610

The antioxidant activity and free radical scavenging capacity of the essential oil and three different extracts of wildly grown Mentha longifolia (M. longifolia) were studied. The essential oil from M. longifolia aerial parts was isolated by hydrodistillation technique using Clevenger-type apparatus. The extracts were prepared with three solvents of different polarity (n-hexane, dichloromethane, and methanol) using Soxhlet extractor. Maximum extract yield was obtained with methanol (12.6?g/100?g) while the minimum with dichloromethane (3.50?g/100?g). The essential oil content was found to be 1.07?g/100?g. A total of 19 constituents were identified in the M. longifolia oil using GC/MS. The main components detected were piperitenone oxide, piperitenone, germacrene D, borneol, and ?-caryophyllene. The total phenolics (TP) and total flavonoids (TF) contents of the methanol extract of M. longifolia were found to be significantly higher than dichloromethane and hexane extracts. The dichloromethane and methanol extracts exhibited excellent antioxidant activity as assessed by 2,2?-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging ability, bleaching ?-carotene, and inhibition of linoleic acid peroxidation assays. The essential oil and hexane extract showed comparatively weaker antioxidant and free radical scavenging activities. The results of the study have validated the medicinal and antioxidant potential of M. longifolia essential oil and extracts. PMID:24224115

The effect of pollen addition and reduction on the fruit and seed production of ground cherry (Physalis longifolia) plants was examined experimentally in the field over an entire flowering season. Pollen levels were manipulated for entire plants by augmenting natural pollination with hand-pollinations and reducing natural pollination by taping half of the flowers closed. These manipulations make it possible to determine if plants are simultaneously resource and pollen limited, a condition that suggests the plant is maximizing seed production given the resources available for female reproduction. Effects of pollen manipulation were dependent on the size of the plant. Large plants responded to reduced pollination by increasing flower production and the number of seeds per fruit; as a result, total seed production did not differ from that of large control plants. In contrast, small plants showed no change in response to reduced pollination, yet seed production did not differ significantly from that of controls, as seed production in both groups was low. Large hand-pollinated plants did not differ significantly from large control plants in any components of yield. In contrast, small hand-pollinated plants had significantly higher percentage fruit set and produced significantly more fruit and seeds than did small control plants. Differences in seed production reflected different proportions of plants that set some rather than no fruit. This may result from low pollinator visitation rates to small plants with small floral displays. Experimental results for large plants are only consistent with the hypothesis that large plants are simultaneously resource and pollen limited. To the extent that there is a trade-off between flower production and seed provisioning, large P. longifolia plants are allocating resources so as to maximize maternal seed production. In contrast, small plants are only pollen limited. PMID:19426083

JACK - ANTHROPOMETRIC MODELING SYSTEM FOR SILICON GRAPHICS WORKSTATIONS  

NASA Technical Reports Server (NTRS)

JACK is an interactive graphics program developed at the University of Pennsylvania that displays and manipulates articulated geometric figures. JACK is typically used to observe how a human mannequin interacts with its environment and what effects body types will have upon the performance of a task in a simulated environment. Any environment can be created, and any number of mannequins can be placed anywhere in that environment. JACK includes facilities to construct limited geometric objects, position figures, perform a variety of analyses on the figures, describe the motion of the figures and specify lighting and surface property information for rendering high quality images. JACK is supplied with a variety of body types pre-defined and known to the system. There are both male and female bodies, ranging from the 5th to the 95th percentile, based on NASA Standard 3000. Each mannequin is fully articulated and reflects the joint limitations of a normal human. JACK is an editor for manipulating previously defined objects known as "Peabody" objects. Used to describe the figures as well as the internal data structure for representing them, Peabody is a language with a powerful and flexible mechanism for representing connectivity between objects, both the joints between individual segments within a figure and arbitrary connections between different figures. Peabody objects are generally comprised of several individual figures, each one a collection of segments. Each segment has a geometry represented by PSURF files that consist of polygons or curved surface patches. Although JACK does not have the capability to create new objects, objects may be created by other geometric modeling programs and then translated into the PSURF format. Environment files are a collection of figures and attributes that may be dynamically moved under the control of an animation file. The animation facilities allow the user to create a sequence of commands that duplicate the movements of a human figure in an environment. Integrated into JACK is a set of vision tools that allow predictions about visibility and legibility. The program is capable of displaying environment perspectives corresponding to what the mannequin would see while in the environment, indicating potential problems with occlusion and visibility. It is also possible to display view cones emanating from the figure's eyes, indicating field of view. Another feature projects the environment onto retina coordinates which gives clues regarding visual angles, acuity and occlusion by the biological blind spots. A retina editor makes it possible to draw onto the retina and project that into 3-dimensional space. Another facility, Reach, causes the mannequin to move a specific portion of its anatomy to a chosen point in space. The Reach facility helps in analyzing problems associated with operator size and other constraints. The 17-segment torso makes it possible to set a figure into realistic postures, simulating human postures closely. The JACK application software is written in C-language for Silicon Graphics workstations running IRIX versions 4.0.5 or higher and is available only in executable form. Since JACK is a copyrighted program (copyright 1991 University of Pennsylvania), this executable may not be redistributed. The recommended minimum hardware configuration for running the executable includes a floating-point accelerator, an 8-megabyte program memory, a high resolution (1280 x 1024) graphics card, and at least 50Mb of free disk space. JACK's data files take up millions of bytes of storage space, so additional disk space is highly recommended. The standard distribution medium for JACK is a .25 inch streaming magnetic IRIX tape cartridge in UNIX tar format. JACK was originally developed in 1988. Jack v4.8 was released for distribution through COSMIC in 1993.

50 Years of ``Scaling'' Jack Kilby's Invention  

NASA Astrophysics Data System (ADS)

This year is the 50th anniversary of Jack Kilby's 1958 invention of the integrated circuit (IC), for which he won the 2000 Nobel Prize in Physics. Since that invention in a laboratory at Texas Instruments, IC components have been continuously miniaturized, which has resulted in exponential improvement trends in their performance, energy efficiency, and cost per function. These improvements have created a semiconductor industry that has grown to over 250B in annual sales. The process of reducing integrated-circuit component size and associated parameters in a coordinated fashion is traditionally called ``feature-size scaling.'' Kilby's original circuit had active (transistor) and passive (resistor, capacitor) components with dimensions of a few millimeters. Today, the minimum feature sizes on integrated circuits are less than 30 nanometers for patterned line widths and down to about one nanometer for film thicknesses. Thus, we have achieved about five orders of magnitude in linear-dimension scaling over the past fifty years, which has resulted in about ten orders of magnitude increase in the density of IC components, a representation of ``Moore's Law.'' As IC features are approaching atomic dimensions, increasing emphasis is now being given to the parallel effort of further diversifying the types of components in integrated circuits. This is called ``functional scaling'' and ``more then Moore.'' Of course, the enablers for both types of scaling have been developed at many laboratories around the world. This talk will review a few of the highlights in scaling and its applications from R&D projects at Texas Instruments.

The development of low cost jack-up installable platforms  

SciTech Connect

In this paper the background for the development of a quite versatile family of small, jack-up installable platforms has been summarized. It has been demonstrated how this development was pioneered in the North Sea by Maersk Olie og Gas AS through the development of the STAR platforms. It has been argued that the design of unmanned platforms should acknowledge the fact that these platforms are unmanned except on special occasions, and therefore not should be designed according to regulations developed for conventional manned platforms. One platform for around 25-m water depth, and two platform concepts for around 70-m water depth, have been described for potential use in the North Sea. It has been demonstrated how the principles for jack-up installation can be further developed for use also on the platforms in 70-m water depth. It is the opinion of the authors, that the jack-up installation option gives a desirable flexibility in the concepts without loosing the standard option of a crane barge installation.

Hadean diamonds in zircon from Jack Hills, Western Australia.  

PubMed

Detrital zircons more than 4 billion years old from the Jack Hills metasedimentary belt, Yilgarn craton, Western Australia, are the oldest identified fragments of the Earth's crust and are unique in preserving information on the earliest evolution of the Earth. Inclusions of quartz, K-feldspar and monazite in the zircons, in combination with an enrichment of light rare-earth elements and an estimated low zircon crystallization temperature, have previously been used as evidence for early recycling of continental crust, leading to the production of granitic melts in the Hadean era. Here we present the discovery of microdiamond inclusions in Jack Hills zircons with an age range from 3,058 +/- 7 to 4,252 +/- 7 million years. These include the oldest known diamonds found in terrestrial rocks, and introduce a new dimension to the debate on the origin of these zircons and the evolution of the early Earth. The spread of ages indicates that either conditions required for diamond formation were repeated several times during early Earth history or that there was significant recycling of ancient diamond. Mineralogical features of the Jack Hills diamonds-such as their occurrence in zircon, their association with graphite and their Raman spectroscopic characteristics-resemble those of diamonds formed during ultrahigh-pressure metamorphism and, unless conditions on the early Earth were unique, imply a relatively thick continental lithosphere and crust-mantle interaction at least 4,250 million years ago.

Herbs in exercise and sports.  

PubMed

The use of herbs as ergogenic aids in exercise and sport is not novel. Ginseng, caffeine, ma huang (also called 'Chinese ephedra'), ephedrine and a combination of both caffeine and ephedrine are the most popular herbs used in exercise and sports. It is believed that these herbs have an ergogenic effect and thus help to improve physical performance. Numerous studies have been conducted to investigate the effects of these herbs on exercise performance. Recently, researchers have also investigated the effects of Eurycoma longifolia Jack on endurance cycling and running performance. These investigators have reported no significant improvement in either cycling or running endurance after supplementation with this herb. As the number of studies in this area is still small, more studies should be conducted to evaluate and substantiate the effects of this herb on sports and exercise performance. For instance, future research on any herbs should take the following factors into consideration: dosage, supplementation period and a larger sample size. PMID:22738233

The Influence of Musical Cadence into Aquatic Jumping Jacks Kinematics  

PubMed Central

The aim of this study was to analyze the relationships between the head-out aquatic exercise “Jumping jacks” kinematics and the musical cadence in healthy and fit subjects. Five young women, with at least one year of experience conducting head- out aquatic programs were videotaped in the frontal plane, with a pair of cameras providing a double projection (above and below the water surface). Subjects performed an incremental protocol of five bouts (120 b·min-1, 135 b·min-1, 150 b·min-1, 165 b·min-1 and 180 b·min-1) with 16 full cycles of the “Jumping jacks” exercise. Data processing and calculation of upper limbs’ (i.e. hands), lower limbs’ (i.e. feet) and center of mass’ 2D linear velocity and displacement were computed with the software Ariel Performance Analysis System and applying the 2D-DLT algorithm. Subjects decreased the cycle period during the incremental protocol. Significant and negative relationships with the musical cadence were verified for the center of mass and upper limbs vertical displacement. On the other hand, for the lower limbs lateral velocity, a significant and positive relationship was observed. It is concluded that expert and fit subjects increase the lower limb’s velocity to maintain the range of motion, while the upper limb’s displacement is reduced to coupe the music cadence. Key points While performing the Jumping Jacks, expert and fit subjects increase their lower limbs segmental velocity to maintain the range of motion. The upper limbs displacement is reduced to maintain the music cadence. Expert and fit subjects present similar response for alternating or simultaneously head-out aquatic exercises when increasing the music cadence. PMID:24149548

Tough new jack-up for rough seas  

SciTech Connect

Rowan Company's new deepwater jack-up, Rowan Gorilla I, is scheduled to spud its initial well off the east coast of Canada later this month for a consortium of oil companies including Bow Valley-Husky and ATS Exploration Ltd. The new rig's class designation--Gorilla--reflects designers' expectations for the drilling unit that is suited to work in virtually all ice-free hostile environmental areas of the world. Rowan's confidence in the design, built by Marathon LeTourneau's Vicksburg, Mississippi yard, is reiterated by the fact that two additional rigs in the Gorilla class are being built. Rowan Gorilla II is being constructed at Marathon's Singapore yard, and the Rowan Gorilla III is in early construction stages at the firm's Vicksburg yard. The three Gorilla-class rigs will cost in excess of $85 million each, including owner-furnished drilling equipment. This, according to owners, will make them among the costliest jack-ups in the world. Another record being claimed by the Gorilla-class drilling units is that they are the largest jack-ups in the world. Fully outfitted, a Gorilla contains 16,000 tons of steel. Its triangular hull measures 297 ft from bow to stern and 292 ft across the stern. The rig has a variable load of 2,750 tons for drilling consumables and 42,265 sq ft of deck space. Its ample storage capacity, along with its 503-ft leg length and certain design features, makes the rig compatible with hostile offshore areas, where it can continue drilling for long periods unattended.

Repellent effect of Salvia dorisiana, S. longifolia, and S. sclarea (Lamiaceae) essential oils against the mosquito Aedes albopictus Skuse (Diptera: Culicidae).  

PubMed

Aedes albopictus (Diptera: Culicidae) has been one of the fastest spreading insects over the past 20 years. Its medical importance is due to the aggressive daytime human-biting behavior and the ability to vector many viruses, including dengue, LaCrosse, Eastern Equine encephalitis and West Nile viruses. In this research, the essential oils (EOs) extracted from fresh air dried leaves of Salvia dorisiana, S. longifolia, and S. sclarea (Lamiaceae) were evaluated for their repellent activity against A. albopictus by using the human-bait technique. The EOs chemical composition was also investigated, and EOs were divided in three different profiles on the basis of their chemical composition: EO with large amount of monoterpenes from S. sclarea, EO rich in oxygenated sesquiterpenes from S. dorisiana, and S. longifolia EO characterized by similar percentages of monoterpenes and sesquiterpenes. The efficacy protection from S. dorisiana, S. longifolia, and S. sclarea EOs, at dosages ranging from 0.004 to 0.4 ?L cm(-2) of skin, was evaluated during 120 min of observation. Results indicated that S. dorisiana, S. longifolia, and S. sclarea EOs had a significant repellent activity (RD(50)?=0.00035, 0.00049, and 0.00101 ?L cm(-2), respectively), with differences in repellency rates, as a function of oil, dosage, and observation time. S. dorisiana was the most effective oil: at the two higher dosages, it gave almost complete protection (with a protective efficacy of 90.99% and 95.62%, respectively) for 90 min. The best protection time was achieved with S. dorisiana essential oil. It ranged from 9.2 to 92.4 min. Protection times of S. longifolia and S. sclarea oils ranged from 3.2 to 60 min, and from 3.6 to 64.2 min, respectively. Our findings clearly reveal that these EOs have a good repellent activity against A. albopictus, therefore they can be proposed to improve the efficacy of repellent formulations against the Asian tiger mosquito.

Unforgivable Blackness: The Rise and Fall of Jack Johnson  

NSDL National Science Digital Library

Jack Johnson, the first African-American heavyweight boxing champion of the world, is the subject of a new documentary by the well-regarded filmmaker Ken Burns. The program recently aired for the first time on PBS, and this companion website offers a number of primary documents, short essays, and educational materials that will be of great interest to the Web-browsing public and educators seeking to use the documentary in the classroom. On the site, visitors can learn about the life of this rather remarkable man, and also learn about the broader social and cultural milieu of the times in which he found himself, both in terms of race relations and in terms of the history of the sport of boxing. One particularly well-developed feature here is the section that deals with âÂÂThe Fight of the CenturyâÂÂ, which pitted Johnson versus Jim Jeffries, who at that point was the retired white heavyweight champion of the world. The site is rounded out by a number of lesson plans and additional resources (such as books and other online sites) for educators.

Coyotes (Canis latrans) from southern Texas were sampled for antibodies to Borrelia burgdorferi from 1980 to 1986; black-tailed jack rabbits (Lepus californicus) and desert cottontails (Sylvilagus audubonii) were sampled in 1986. Coyote fetuses, adult coyote kidneys, and black-tailed jack rabbit and desert cottontail kidneys were cultured for B. burgdorferi in 1986. Results of indirect immunofluorescent antibody (IFA) tests for B. burgdorferi in coyotes were as follows (number positive at a dilution of greater than or equal to 1:128/number tested): 1980 (0 of 30), 1981 (0 of 21), 1982 (0 of 53), 1983 (0 of 78), 1984 (47 of 97), 1985 (20 of 88), and 1986 (42 of 80). Eight of 26 black-tailed jack rabbits and two of seven desert cottontails tested in 1986 had IFA titers to B. burgdorferi of greater than or equal to 1:128. Borrelia burgdorferi was isolated from one of five coyote fetuses, three of 31 adult coyote kidneys, and two of 10 black-tailed jack rabbit kidneys in 1986. These results indicate that B. burgdorferi infection has been present in coyotes in Texas, at least since 1984 and that transplacental transmission occurs. PMID:2644452

Is there really carbon in the detrital zircons from Jack Hills, Western Australia?  

NASA Astrophysics Data System (ADS)

We have previously reported the discovery of graphite and diamond inclusions in detrital zircon grains from the Jack Hills in Western Australia, with the oldest inclusion-bearing zircon being 4,252 Myrs (Menneken et al. 2007). When the diamond inclusions were first identified by Raman spectroscopy, several characteristics were taken as evidence against possible contamination from diamond polishing powder used to prepare the samples. Some diamond inclusions appeared larger than the grain-size of the diamond polishing powder, while most of them were associated with graphite. Raman spectra of the diamond inclusions were clearly different to those from diamond particles in the polishing powder. Also, the extremely large spread of carbon isotope compositions of the diamond-graphite composite inclusions with ?13C values extending from -58 to -5 per mil argued against contamination, as both synthetic and natural diamonds have a narrow range of carbon isotope composition (Nemchin et al. 2008). In this study, we have applied transmission electron microscopy (TEM) and Raman spectroscopy on focussed ion beam sections cut from a fully embedded diamond inclusion and a fully embedded carbon inclusion in two zircon grains from Jack Hills. Results show that the graphitic material is not a solid inclusion, but covers the walls of a void as a 10-20 nm thick layer. Since we identified numerous CO2 inclusions in the same host zircon by Raman spectroscopy, it is likely that this inclusion was once filled with CO2 On the other hand, similar to a study by Dobrzhinetskaya et al. (2014), performed on surface diamond-graphite inclusions from one of our samples, we found that the embedded diamond inclusion consists of several hundred nano-meter large angular diamond fragments mixed with some gold particles. This is strong evidence that the embedded diamond particles originated from the diamond polishing powder. The diamond particles could enter the cavity through an opening 2 - 3 ?m wide. Previously, we considered it impossible to remove and insert apparently larger solid minerals through such narrow openings during the polishing process. However, newly discovered CO2 inclusions along with graphite in Jack Hill zircons indicate that diamond grains from the polishing paste likely entered into cavities that were originally filled with CO2 and coated with graphite-like carbon, generating artificial graphite-diamond composite inclusions Dobrzhinetskaya et al.

Estuaries as nurseries for the jacks Caranx ignobilis and Caranx melampygus (Carangidae) in Hawaii  

USGS Publications Warehouse

Estuaries provide juvenile nursery habitat for many species of fish that inhabit marine environments as adults. In Hawaii, some juvenile Caranx ignobilis and Caranx melampygus occupy estuaries opportunistically before moving to nearshore ocean habitats. This study examined the extent and nature of estuarine habitat available in the lower Hanalei River of Kauai, the relative abundance and distribution of jacks in the estuary, and their diets. Salinity measurements indicated that the upstream extent of saltwater ranged from the mouth to nearly 5 km upriver and was strongly influenced by the variable river discharge. Juvenile jacks between 80 and 310 mm FL were observed on underwater transects over the full range of mixohaline conditions. Hand-operated seine collections produced overall catch rates of ???0.64 fish/haul for each of these species. The two jacks ate much the same spectrum of food items. C. ignobilis was somewhat more piscivorous than C. melampygus, as determined by measures of frequency of predation and number and bulk of prey. Data for length at age, incorporating daily otolith increment counts from these estuarine juveniles and previous counts from non-estuarine specimens, were fitted to a lifetime von Bertalanffy growth model. The results greatly extended the age range of the model and suggested that growth rates were not much different between estuarine and non-estuarine fish. ?? 2002 Elsevier Science Ltd.

Jack vertebral dilator kyphoplasty for treatment of osteoporotic vertebral compression fractures.  

PubMed

Osteoporotic vertebral compression fractures (OVCFs) are common in the elderly population and often involve the thoracolumbar vertebrae. Clinical symptoms of OVCFs include severe pain, loss of vertebral height, progressive kyphosis and increased mortality. Jack vertebral dilator kyphoplasty is a recently developed OVCFs treatment modality, with few systematic studies present in the literature. This retrospective study was designed to investigate the safety and efficacy of Jack vertebral dilator kyphoplasty for treating thoracolumbar OVCFs. Sixteen elderly patients (55-85 years) with solitary thoracolumbar OVCFs were treated with this procedure and followed-up (10-27 months). The amount of injected bone cement and operative time, preoperative and postoperative visual analogue scores, anterior and middle vertebral body heights, local kyphosis angle, and complications was analysed. The results showed that the method provided long-term pain relief and restoration of the vertebral body height and spinal alignment. No serious complications occurred, but two patients experienced recompression of the vertebral body, and one patient experienced cement leakage into a disc. In conclusion, Jack vertebral dilator kyphoplasty is a safe and effective minimally invasive procedure for treatment of OVCFs. PMID:23412256

Signals from the ancient geodynamo: A paleomagnetic field test on the Jack Hills metaconglomerate  

NASA Astrophysics Data System (ADS)

The oldest history of Earth's magnetic field cannot be directly read from extant bulk rocks because of subsequent metamorphism at temperatures close to or exceeding the Curie temperature of common magnetic minerals. The Jack Hills metasediments of Western Australia, which have seen lower peak metamorphic temperatures, contain zircons as old as ˜4.4 billion-yr-old. To assess whether these sediments can retain an ancient signal of the geodynamo, we present a paleomagnetic conglomerate test on a cobble-bearing Jack Hills unit. Thermal demagnetization reveals a distinct magnetic component with high unblocking temperatures between ˜550 and 580 °C that passes the conglomerate test, indicating magnetization prior to deposition of the conglomerate. This result, together with rock magnetic data, indicates that the high unblocking temperature component is carried by magnetite which records magnetization in an ambient field, and the simplest explanation is that a dynamo was present. Existing geochronological data imply that the clasts could contain mixtures of minerals extending to ages only slightly older than the maximum depositional age at 3.05 billion-yr-ago. However, the positive conglomerate test reported here indicates that the Jack Hills metasediments have the potential to record Paleorchean to Hadean magnetic fields, on a clast or sub-clast mineral scale.

Neuroaxonal dystrophy in a Jack Russell terrier pup resembling human infantile neuroaxonal dystrophy.  

PubMed

A 9-week-old Jack Russell terrier with progressive ataxia had histopathological lesions consistent with neuroaxonal dystrophy. Gross observation revealed absence of the septum pellucidum, hypoplasia of the corpus callosum and marked bilateral hydrocephalus. Light microscopy of the CNS revealed extensive axonal swellings principally in the gray matter of the brain stem where the sensory nuclei were most affected. Ultrastructurally, spheroids were identified as axonal terminals and probably dystrophic boutons; they were characterized by accumulations of membrane bound bodies. Clinical and morphological findings are similar to those identified in human infantile neuroaxonal dystrophy (Seitelberger's disease). PMID:8467699

BOREAS RSS-4 1994 Southern Study Area Jack Pine LAI and FPAR Data  

NASA Technical Reports Server (NTRS)

The RSS-4 team collected several data sets related to leaf, plant, and stand physical, optical, and chemical properties. This data set contains leaf area indices and FPAR measurements that were taken at the three conifer sites in the BOREAS SSA during August 1993 and at the jack pine tower flux and a subset of auxiliary sites during July and August 1994. The measurements were made with LAI-2000 and Ceptometer instruments. The measurements were taken for the purpose of model parameterization and to test empirical relationships that were hypothesized between biophysical parameters and remotely sensed data. The data are stored in tabular ASCII files.

GPR measurements for the distribution of thixotropic slurry behind segments in large diameter and long distance pipe-jacking construction  

NASA Astrophysics Data System (ADS)

It is very important to form an integrated ring of thixotropic slurry around the pipe segments to reduce resistance during large diameter and long distance pipe jacking. Furthermore, the integrated slurry ring between the pipe and the excavated soil can effectively reduce the soil disturbance caused by the pipes, and minimize ground settlement. It is necessary to real-time monitor the spatial distribution of the thixotripic slurry during jacking process. The traditional solution to estimate the outlines of slurry ring is the jacking load and the injecting pressure. If the jacking load increases, which means more slurry should be injected to reduce the jacking load. However, this solution couldn't provide the distribution of the slurry beneath pipe segments, and locate the zones which need to be injected enough slurry. Ground penetrating radar (GPR) has been successfully used to detect the thickness of the grouting behind the shield tunnel segments in last several years. An important factor is the dielectric difference between grouting and soil. Similarly, the interface between the liquid slurry with high relative electric permittivity and surrounding soil, should be recognized from GPR image due to the distinct dielectric difference. Here, GPR experiment has been conducted on a sewage pipe jacking engineering. The purpose of the survey is to evaluate the distribution of the thixotropic slurry through GPR image. In this sewage jacking engineering, the width and the thickness of each pipe segments is 200 cm and 30 cm, respectively. Considering the resolution and propagation range of radar wave, ground coupled bowtie antenna of 900 MHz frequency has been selected for GPR data acquisition. A series of circular GPR data have been collected along the inner surface of pipe segments. In addition, sampling of slurry has been performed on four different segments. The relative electric permittivity and conductivity of the thixotropic slurry have been measured by using time domain reflectometer (TDR). The velocity of propagation in slurry is calculated by dielectric characteristics, which extremely improves the resolution of time-depth conversion. Some process methods, including moving average, AGC and migration, have been applied to improve the quality of each GPR images. It's possible to recognize the reflection wave from the slurry-soil interface from the processed images. Combined the exact velocity estimation, the two-way travel time between pipe-slurry and slurry-soil interfaces can be converted to the thickness of the slurry ring. The experiment results show that GPR is able to evaluate the distribution of the liquid thixotropic slurry behind pipe segments in large diameter and long distance jacking. The velocity measured by TDR can significantly reduce the error caused by the time-depth conversion.

Sneaker "jack" males outcompete dominant "hooknose" males under sperm competition in Chinook salmon (Oncorhynchus tshawytscha).  

PubMed

In a variety of taxa, males deploy alternative reproductive tactics to secure fertilizations. In many species, small "sneaker" males attempt to steal fertilizations while avoiding encounters with larger, more aggressive, dominant males. Sneaker males usually face a number of disadvantages, including reduced access to females and the higher likelihood that upon ejaculation, their sperm face competition from other males. Nevertheless, sneaker males represent an evolutionarily stable strategy under a wide range of conditions. Game theory suggests that sneaker males compensate for these disadvantages by investing disproportionately in spermatogenesis, by producing more sperm per unit body mass (the "fair raffle") and/or by producing higher quality sperm (the "loaded raffle"). Here, we test these models by competing sperm from sneaker "jack" males against sperm from dominant "hooknose" males in Chinook salmon. Using two complementary approaches, we reject the fair raffle in favor of the loaded raffle and estimate that jack males were ?1.35 times as likely as hooknose males to fertilize eggs under controlled competitive conditions. Interestingly, the direction and magnitude of this skew in paternity shifted according to individual female egg donors, suggesting cryptic female choice could moderate the outcomes of sperm competition in this externally fertilizing species.

Effects of a clear-cut harvest on soil respiration in a jack pine - Lichen woodland  

USGS Publications Warehouse

Quantification of the components of ecosystem respiration is essential to understanding carbon (C) cycling of natural and disturbed landscapes. Soil respiration, which includes autotrophic and heterotrophic respiration from throughout the soil profile, is the second largest flux in the global carbon cycle. We measured soil respiration (soil CO2 emission) at an undisturbed mature jack pine (Pinus banksiana Lamb.) stand in Saskatchewan (old jack pine, OJP), and at a formerly continuous portion of the stand that was clear-cut during the previous winter (clear-cut, CC). Tree harvesting reduced soil CO2 emission from ???22.5 to ???9.1 mol CO2??m2 for the 1994 growing season. OJP was a small net sink of atmospheric CO2, while CC was a net source of CO2. Winter emissions were similar at both sites. Reduction of soil respiration was attributed to disruption of the soil surface and to the death of tree roots. Flux simulations for CC and OJP identify 40% of CO2 emission at the undisturbed OJP site as near-surface respiration, 25% as deep-soil respiration, and 35% as tree-root respiration. The near-surface component was larger than the estimated annual C input to soil, suggesting fast C turnover and no net C accumulation in these boreal uplands in 1994.

Despite Kerouac's desire to be known primarily as a writer, many remember him because of his iconic status as a leader of the so-called "Beat Generation". Perhaps his best known work is his sprawling, stream of consciousness travel narrative, "On The Road". Recently, the book celebrated its fiftieth anniversary in print, and while Kerouac has been gone for almost forty years, the original manuscript of this book continues to travel through the United States. The entire work is contained on a 120-foot scroll, consisting of a series of single-spaced typed twelve-foot long rolls of paper that have been taped together. This remarkable document has been traveling around the country for the past few years at the request of its owner, Jim Irsay, who also happens to own the Indianapolis Colts. Recently, the scroll went home, in a matter of speaking, as it began a four-month residency at the Boot Cotton Mills Museum in Lowell, Massachusetts. As Lowell is Kerouac's birthplace, it seems fitting that it will get a chance to be around the places and milieu that informed a good deal of his own writings, musings, and reflections.

Study on the design method of the jack-up's x-type cantilever allowable load nephogram  

NASA Astrophysics Data System (ADS)

The extending of a cantilever and transverse moving of a drilling floor enable the jack-up to operate in several well positions after the Jack-up has pitched. The cantilever allowable load nephogram is the critical reference which can evaluate the jack-up's drilling ability, design the cantilever structure and instruct a jack-up manager to make the operations safe. The intent of this paper is to explore the interrelationships between the cantilever position, drilling floor and the loads including wind force, the stand set-back weight etc., through analyzing the structure and load characteristics of the x-type cantilever and the simplified mechanics model with the restriction of the maximum moment capacity of the cantilever single side beam. Referring to several typical position designs load values, the cantilever allowable load nephogram is obtained by using the suitable interpolation method. The paper gives a method for cantilever allowable load design, which is proved reliable and effective by the calculation example.

Using Transom Jack in the Human Engineering Analysis of the Materials Science Research Rack-1 and Quench Module Insert  

NASA Technical Reports Server (NTRS)

This paper describes the human engineering analysis performed on the Materials Science Research Rack-1 and Quench Module Insert (MSRR-1/QMI) using Transom Jack (Jack) software. The Jack software was used to model a virtual environment consisting of the MSRR-1/QMI hardware configuration and human figures representing the 95th percentile male and 5th percentile female. The purpose of the simulation was to assess the human interfaces in the design for their ability to meet the requirements of the Pressurized Payloads Interface Requirements Document - International Space Program, Revision C (SSP 57000). Jack was used in the evaluation because of its ability to correctly model anthropometric body measurements and the physical behavior of astronauts working in microgravity, which is referred to as the neutral body posture. The Jack model allows evaluation of crewmember interaction with hardware through task simulation including but not limited to collision avoidance behaviors, hand/eye coordination, reach path planning, and automatic grasping to part contours. Specifically, this virtual simulation depicts the human figures performing the QMI installation and check-out, sample cartridge insertion and removal, and gas bottle drawer removal. These tasks were evaluated in terms of adequate clearance in reach envelopes, adequate accessibility in work envelopes, appropriate line of sight in visual envelopes, and accommodation of full size range for male and female stature maneuverability. The results of the human engineering analysis virtual simulation indicate that most of the associated requirements of SSP 57000 were met. However, some hardware design considerations and crew procedures modifications are recommended to improve accessibility, provide an adequate work envelope, reduce awkward body posture, and eliminate permanent protrusions.

[Malignant narcissism and sexual homicide--exemplified by the Jack Unterweger case].  

PubMed

With the syndrome of malignant narcissism, which is characterised by narcissistic personality disorder, anti-social behaviour, sadism and a marked tendency to paranoid reactions, Kernberg (1985, 1996) describes an independent form of pathological narcissism. According to Stone (1996) this is found in many mass-murderers and serial killers. On the basis of the example of Jack Unterweger the connection between malignant narcissism and sexual offence is discussed as to psychodynamic development, personality structure and psychopathology. Unterweger, who was convicted to lifelong imprisonment in 1976 for sadistic sexual murder, became a wellknown writer in prison and was released prematurely in 1990 as the Austria case of successful rehabilitation. As stated in the sentence passed against him he killed 11 prostitutes in Europe and the USA within the next 18 months, but never pleaded guilty. Psychiatric examination revealed numerous elements of malignant narcissism and the constellation of his development and life was typical of serial offenders. PMID:10489586

PIXE analysis of urease isoenzymes isolated from Canavalia ensiformis (jack bean) seeds  

NASA Astrophysics Data System (ADS)

The main goal of this work was to perform a stoichiometric analysis of metals, in particular Ni and Zn, in two isoforms of urease isolated from jack bean seeds. The urease isoforms were separated by immobilized metal affinity chromatography. The samples were prepared for PIXE by acetone precipitation of the proteins, which were deposited onto regenerated cellulose acetate membranes by filtration. The resulting mass of the samples was of the order of 0.20 mg (dry weight). The results show that urease contains two equivalents of Ni per 90 kDa monomer, in agreement with the results reported in the literature. For canatoxin, the other urease isoform, the presence of one equivalent of Zn per monomer was observed, besides Ni, previously detected by atomic absorption spectrometry as one equivalent per 90 kDa. Problems and further improvements concerning the preparation of the samples are discussed.

Diamonds in Earth?s oldest zircons from Jack Hills conglomerate, Australia, are contamination  

NASA Astrophysics Data System (ADS)

The earliest period of Earth history is the Hadean era (4600-4000 Myr) but to date no rocks are known to be preserved from this time. However, abundant detrital zircons from the Archean Jack Hills conglomerate complex of Western Australia have been found with dates in excess of 4000 Myr and there is a significant literature concerning these zircons from which abundant geochemical and mineralogical information has been obtained. The essence of what has been derived from these zircons and their inclusions concerning conditions of formation is that the zircons crystallized from granitic melts at shallow depths. However, in the last decade two papers were published reporting microdiamond inclusions in a suite of zircons ranging in age from ?4200 Myr to ?3000 Myr, implying much greater depths and repeated recycling and re-incorporation of diamonds into zircons over at least 1200 Myr. To complicate the issue, subsequent to this discovery, another study surveyed the inclusion suite in a very large sample (>400) of Jack Hills zircons (JHZs) and found no diamonds but abundant inclusions that are consistent with the previous consensus. It is important, therefore, to verify whether or not the reported JHZ diamonds could be laboratory contamination because diamond abrasive paste was used for sample preparation. Here, we report very-high-resolution re-examination of the original diamond-bearing specimens that were kindly provided to us by the authors (see Acknowledgements). We confirm the presence of diamonds in their zircons but the diamonds we find are fragments of polishing compound. These results combined with the lack of diamonds in any other samples of JHZs strongly suggest that there are no indigenous diamonds in the JHZs.

Mid-Proterozoic detrital zircons and the depositional history of the Jack Hills (Narryer Gneiss Complex, Western Australia)  

NASA Astrophysics Data System (ADS)

Quartz-biotite schists ("metaconglomerates" s.l.) in the Jack Hills outcrops of the Narryer Terrane of Western Australia host detrital >4 Ga zircons. These rocks are presumed to have been deposited at about 3 Ga and subsequently experienced metamorphism and granite intrusion at 2.45-2.6 Ga. Protoliths of the oldest detrital zircon population (>3.8 Ga) have not yet been identified, and the post-2.6 Ga history of the Jack Hills remains murky. Rare metavolcanic units are documented at ca. 1.8-1.9 Ga. Some metasediments near the Hadean zircon "discovery" site that are apparently young enough to have incorporated mid-Proterozoic detrital zircons are evidence of further geologic activity, although it is possible that these rocks were tectonically juxtaposed later. To further resolve the Proterozoic history of the Jack Hills, we report U-Pb age data for 60 detrital zircons extracted from two quartzites from the eastern Jack Hills (~50 km distant from the "discovery" site of Hadean zircons); in this sample suite 26 concordant zircons range in age from 0.168-3.49 Ga, with an age peak at ca. 2.6 Ga and a scattering of ages from 1.06-2.0 Ga. Zircon sources <1.8 Ga have not so far been identified in the Narryer Terrane and may point to far-field sediment transport. Several ca. 1.07 Ga zircons may derive from the Warakurna Large Igneous Province of the same age, which extends through much of central and Western Australia. One concordant zircon with a 206Pb/238U age of 0.166±6 Ga displays a patchy internal texture indicative of alteration; all other concordant grains are >1.06 Ga. Only 2 concordant zircons display ages >3 Ga, unlike the dominant mid-Archean signature from other reported Proterozoic sediments in the Jack Hills. All told, these quartzites display a significantly different provenance than other previously studied units from the terrane, with decreased importance of mid-Archean zircon sources and significantly younger (<1.06 Ga) ages of sedimentation than previously recognized. If the various quartzites are autochthonous, the absence of mid-Archean zircons despite the units' current proximity to the mid-Archean Narryer Gneiss Complex, as well as the likely sourcing of Warakurna LIP detritus, would appear to have implications for paleogeographic reconstructions of the Jack Hills region.

Comparison of lodgepole and jack pine resin chemistry: implications for range expansion by the mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae).  

PubMed

The mountain pine beetle, Dendroctonus ponderosae, is a significant pest of lodgepole pine in British Columbia (BC), where it has recently reached an unprecedented outbreak level. Although it is native to western North America, the beetle can now be viewed as a native invasive because for the first time in recorded history it has begun to reproduce in native jack pine stands within the North American boreal forest. The ability of jack pine trees to defend themselves against mass attack and their suitability for brood success will play a major role in the success of this insect in a putatively new geographic range and host. Lodgepole and jack pine were sampled along a transect extending from the beetle's historic range (central BC) to the newly invaded area east of the Rocky Mountains in north-central Alberta (AB) in Canada for constitutive phloem resin terpene levels. In addition, two populations of lodgepole pine (BC) and one population of jack pine (AB) were sampled for levels of induced phloem terpenes. Phloem resin terpenes were identified and quantified using gas chromatography. Significant differences were found in constitutive levels of terpenes between the two species of pine. Constitutive ?-pinene levels - a precursor in the biosynthesis of components of the aggregation and antiaggregation pheromones of mountain pine beetle - were significantly higher in jack pine. However, lower constitutive levels of compounds known to be toxic to bark beetles, e.g., 3-carene, in jack pine suggests that this species could be poorly defended. Differences in wounding-induced responses for phloem accumulation of five major terpenes were found between the two populations of lodgepole pine and between lodgepole and jack pine. The mountain pine beetle will face a different constitutive and induced phloem resin terpene environment when locating and colonizing jack pine in its new geographic range, and this may play a significant role in the ability of the insect to persist in this new host.

Soil respiration in a fire scar chronosequence of Canadian boreal jack pine forest  

NASA Astrophysics Data System (ADS)

To fully understand the carbon (C) cycle impacts of forest fires, both C emissions during the fire and post-disturbance fluxes need to be considered. The latter are dominated by soil respiration (Rs), which is still subject to large uncertainties. This research investigates Rs in a boreal jack pine fire scar chronosequence at Sharpsand Creek, Ontario, Canada. During two field campaigns in 2006 and 2007, Rs was measured in a chronosequence of fire scars aged between 0 and 59 years since the last fire. Mean Rs per fire scar was adjusted for soil temperature (Ts) and soil moisture (Ms) (denoted RST,M). RST,M ranged from 0.56 ?mol CO2/m2/s (32 years post fire) to 8.18 ?mol CO2/m2/s (58 years post fire). The coefficient of variation (CV) of RST,M ranged from 20% (16 years post fire) to 56% (58 years post fire). Across the field site, there was a statistically highly significant exponential relationship between Rs adjusted for soil organic carbon (Cs) and Ts (P<0.00001; Q10=2.21) but no effect of Ms on Rs adjusted for Cs and Ts for the range 0.21 to 0.77 volumetric Ms (P=0.702). RST,M decreased significantly (P=0.030) after fire (4 to 8 days post fire) in mature forest, though no significant (P>0.1) difference could be detected between recently burned (4 to 8 days post fire) and unburned young forest. There were significant differences in RST,M between recently burned (4 to 8 days post fire) scar age categories that differed in their burn history, with between-fire intervals of 32 vs. 16 years (P<0.001) and 32 vs 59 years (P=0.044). There was a highly significant exponential increase in RST,M with time since fire (r2=0.999; P=0.006) for the chronosequence 0, 16 and 59 years post fire, and for all these age categories, RST,M was significantly different from one another (P<0.05). The results of this study contribute to a better quantitative understanding of Rs in boreal jack pine fire scars and will facilitate improvements in C cycle modelling. Further work is needed in quantifying autotrophic and heterotrophic contributions to Rs in jack pine systems; in monitoring Rs for extended time periods after fire; and in measuring different fire-prone forest types.

Post-Hadean transitions in Jack Hills zircon provenance: A signal of the Late Heavy Bombardment?  

NASA Astrophysics Data System (ADS)

Hadean Jack Hills (Western Australia) detrital zircons represent the best documented terrestrial resource with which to observe the pre-4 Ga Earth. The >4 Ga component of this semi-continuous 4.38 to 3.0 Ga zircon record has been investigated in detail for age, ?18O, Lu-Hf systematics, and Ti thermometry. The more abundant post-Hadean population is less well-characterized, but a previous study (Bell et al., 2011) suggests a more restricted range of ?18O source materials together with a ca. 4.0-3.6 Ga discontinuity in Lu-Hf evolution. These differences could reflect a transformation in the character of the older zircon source region or their sourcing from different terranes entirely. The relative scarcity of 4.0-3.6 Ga zircons corresponds to a discontinuity in Lu-Hf evolution after which 176Hf/177Hf in zircon reverts to more radiogenic values relative to the >4 Ga population. We present new oxygen isotope, titanium, and trace element results for 4.0-3.6 Ga Jack Hills zircons in a search for apparent transitions in petrological conditions. Post-3.8 Ga zircons show a marked decrease in the occurrence of heavy oxygen (>6.5‰), but remain close to the average of the Hadean distribution despite their restricted range. This may point to the decreased importance of sedimentary materials in post-3.8 Ga magmas. Ca. 3.9 Ga zircons fall into two categories: “Group I” displays temperatures and compositions similar to the Hadean zircons whereas “Group II” zircons have higher U and Hf, and lower (Th/U), Ce and P. Group II zircons also have anomalously low Ti, and are remarkably concordant in the U-Pb system. Group II's geochemical characteristics are consistent with formation by transgressive recrystallization (Hoskin and Black, 2000), in which non-essential structural constituents are purged during high-grade thermal metamorphism. The restricted age range of Group II occurrence (3.91-3.84) and its coincidence with the postulated intense bolide flux in the inner solar system (i.e., Late Heavy Bombardment; 3.95-3.85) may have causal significance.

Review of the crevalle jacks, Caranx hippos complex (Teleostei: Carangidae), with a description of a new species from West Africa  

USGS Publications Warehouse

The Caranx hippos species complex comprises three extant species: crevalle jack (Caranx hippos) (Linnaeus, 1766) from both the western and eastern Atlantic oceans; Pacific crevalle jack (Caranx caninus) Gu??nther, 1868 from the eastern Pacific Ocean; and longfin crevalle jack (Caranx fischeri) new species, from the eastern Atlantic, including the Mediterranean Sea and Ascension Island. Adults of all three species are superficially similar with a black blotch on the lower half of the pectoral fin, a black spot on the upper margin of opercle, one or two pairs of enlarged symphyseal canines on the lower jaw, and a similar pattern of breast squamation. Each species has a different pattern of hyperostotic bone development and anal-fin color. The two sympatric eastern Atlantic species also differ from each other in number of dorsal- and anal-fin rays, and in large adults of C. fischeri the lobes of these fins are longer and the body is deeper. Caranx hippos from opposite sides of the Atlantic are virtually indistinguishable externally but differ consistently in the expression of hyperostosis of the first dorsal-fin pterygiophore. The fossil species Caranx carangopsis Steindachner 1859 appears to have been based on composite material of Trachurus sp. and a fourth species of the Caranx hippos complex. Patterns of hyperostotic bone development are compared in the nine (of 15 total) species of Caranx sensu stricto that exhibit hyperostosis.

Statistical studies on high molecular weight pullulan production in solid state fermentation using jack fruit seed.  

PubMed

The purpose of the work was to optimize the medium variables for maximizing pullulan production using jack fruit seed as a low cost substrate by Aureobasidium pullulans in solid state fermentation. Effects of K2HPO4, KH2PO4, ZnSO4·5H2O, MgSO4·7H2O, NaCl, (NH4)2SO4·5H2O, yeast extract, moisture content (%, w/w) in the production medium on pullulan production were studied using Plackett-Burman design. Production of pullulan was significantly affected by the medium variables namely KH2PO4, ZnSO4·5H2O, NaCl and moisture content (%, w/w). Then screened variables were optimized by Box Behnken experiment design. The pullulan obtained was characterized and confirmed by FTIR, (1)H NMR and (13)C NMR. Molecular weight of pullulan was found to be 1.733×10(6) g/mol by gel permeation chromatography (GPC). PMID:23987421

Inactivation of jack bean urease by scutellarin: elucidation of inhibitory efficacy, kinetics and mechanism.  

PubMed

In the present study, the inactivation effect of scutellarin (SL) on jack bean urease was investigated to elucidate the inhibitory potency, kinetics and mechanism of inhibition. It was revealed that SL acted as a concentration- and time-dependent inactivator of urease characteristic of slow-binding inhibition with an IC50 of 1.35±0.15 mM. The rapid formation of the initial SL-urease complex with an inhibition constant of Ki=5.37×10(-2) mM was followed by a slow isomerization into the final complex with the overall inhibition constant of Ki*=3.49×10(-3) mM. High effectiveness of thiol protectors, such as L-cysteine (L-cys), 2-mercaptoethanol (2-ME) and dithiothreitol (DTT) significantly slowed down the rate of inactivation, indicating the strategic role of the active site sulfhydryl group in the blocking process. While the insignificant protection by boric acid and fluoride from the inactivation further confirmed that the active site cysteine should be obligatory for urease inhibition, which was also rationalized by the molecular docking study. The inhibition of SL on urease proved to be reversible since SL-blocked urease could be reactivated by DTT application and multidilution. The results obtained indicated that urease inactivation resulted from the reaction between SL and the sulfhydryl group. PMID:23978581

A light carbon reservoir recorded in zircon-hosted diamond from the Jack Hills.  

PubMed

The recent discovery of diamond-graphite inclusions in the Earth's oldest zircon grains (formed up to 4,252 Myr ago) from the Jack Hills metasediments in Western Australia provides a unique opportunity to investigate Earth's earliest known carbon reservoir. Here we report ion microprobe analyses of the carbon isotope composition of these diamond-graphite inclusions. The observed delta(13)C(PDB) values (expressed using the PeeDee Belemnite standard) range between -5 per mil and -58 per mil with a median of -31 per mil. This extends beyond typical mantle values of around -6 per mil to values observed in metamorphic and some eclogitic diamonds that are interpreted to reflect deep subduction of low-delta(13)C(PDB) biogenic surface carbon. Low delta(13)C(PDB) values may also be produced by inorganic chemical reactions, and therefore are not unambiguous evidence for life on Earth as early as 4,250 Myr ago. Regardless, our results suggest that a low-delta(13)C(PDB) reservoir may have existed on the early Earth. PMID:18596808

What to copy: the key factor of observational learning in striped jack (Pseudocaranx dentex) juveniles.  

PubMed

Animals in social environments can enhance their learning efficiency by observing the behaviour of others. Our previous study showed that learning efficiency of schooling fish increased through the observation of the behaviour of trained demonstrator conspecifics. The present study aimed to verify the key factor of observational learning by investigating what information is important for social transmission of feeding information. A striped jack (Pseudocaranx dentex) observer was provided with one of the five observation treatments: (a) pellets observation, where pellets were dropped near the aeration in an adjacent tank; (b) responding conspecific observation, where a trained conspecific demonstrator responded to the aeration without food in the adjacent tank; (c) foraging conspecific observation, where a conspecific demonstrator foraged near the aeration in the adjacent tank; (d) nearby pellets observation, where pellets were dropped in a transparent column near the aeration in the observer tank; and (e) foraging heterospecific observation, where a filefish (Stephanolepis cirrhifer) demonstrator foraged near the aeration in the adjacent tank. The response to the aeration in these observers was compared with that of controls who did not observe any behaviour. Only individuals who observed foraging conspecifics showed a response to the aeration after observing. These results suggest that observer fish acquire feeding information not through recognition of prey items or through imitation of the demonstrator, but through the vicarious reinforcement of a conspecific for foraging.

Development of observational learning during school formation in jack mackerel Trachurus japonicus juveniles.  

PubMed

We assessed whether the development of observational learning in jack mackerel Trachurus japonicus juveniles corresponds with that of their schooling behaviour. Schooling behaviour was quantitatively analyzed by nearest neighbour distance and separation angle in two size classes of fish, 20-mm and 40-mm in body length. Observer and non-observer fish with matching sizes were conditioned to pellets by temporarily stopping aeration. Observer fish were provided with five observation trials of other individuals feeding near an air stone when aeration was stopped. After the observation trial, fish were conditioned to pellets with the stop of aeration, and then the learning process was evaluated by the increase in the association with the feeding area when aeration was stopped. In 20-mm fish, which were at an immature stage of schooling behaviour, there was no difference in the learning process between observer and non-observer fish. In contrast, 40-mm fish were confirmed to have a well-developed schooling behaviour, and the observer learnt the feeding area more efficiently than the non-observer. This study provides evidence that observational learning develops along with the development of the social interaction. PMID:24220796

Multiple intermediate conformations of jack bean urease at low pH: anion-induced refolding.  

PubMed

Structural and functional characteristics of jack bean urease (JBU), a hexameric enzyme having identical subunits, were investigated under neutral as well as acidic conditions by using CD, fluorescence, ANS binding and enzyme activity measurements. At low pH and low ionic strength, JBU exists in a partially unfolded state (U(A)-state), having predominantly beta structure and no tertiary interactions along with a strong ANS binding. Addition of salts like NaCl, KCl and Na(2)SO(4) to the U(A)-state induces refolding resulting in structural propensities similar to that of native hexamer. Moreover, at low concentrations, GuHCl behaves like an anion by inducing refolding of the U(A)-state. The anion-induced refolded state (I(A)-state) is more stable than U(A)-state and the stability is nearly equal to that of the native protein against chemical-induced and thermal denaturation. Overall, these observations support a model of protein folding for a multimeric protein where certain conformations (ensembles of substates) of low energy prevail and populated under non-native conditions with different stability.

Morphological Phylogenetic Analysis of Seven Varieties of Ficus deltoidea Jack from the Malay Peninsula of Malaysia  

PubMed Central

This study is the first report to suggest a morphological phylogenetic framework for the seven varieties of Ficus deltoidea Jack (Ficus: Moraceae) from the Malay Peninsula of Malaysia. Several molecular-based classifications on the genus Ficus had been proposed, but neither had discussed the relationship between seven varieties of F. deltoidea to its allies nor within the varieties. The relationship between seven varieties of F. deltoidea is still debated due to the extreme morphological variabilities and ambiguous boundaries between taxa. Thus, the correct identification of these varieties is important as several morphological characters are variety-specific. To test the monophyly and further resolved the relationship in F. deltoidea, a morphological phylogenetic analysis was conducted based on herbarium specimens representing the seven varieties of F. deltoidea that were collected from the Malay Peninsula of Malaysia, by using related species of the genus Ficus; F. grossularioides, F. ischnopoda and F. oleifolia as the outgroups. Parsimony and neighbour-joining analyses indicated that F. deltoidea is monophyletic, in that the seven varieties of F. deltoidea nested into two clades; clade subspecies deltoidea (var. deltoidea, var. bilobata, var. angustifolia, var. kunstleri and var. trengganuensis) and clade subspecies motleyana (var. intermedia and var. motleyana).

Jack bean ?-mannosidase: amino acid sequencing and N-glycosylation analysis of a valuable glycomics tool.  

PubMed

Jack bean (Canavalia ensiformis) seeds contain several biologically important proteins among which ?-mannosidase (EC 3.2.1.24) has been purified, its biochemical properties studied and widely used in glycan analysis. In the present study, we have used the purified enzyme and derived its amino acid sequence covering both the known subunits (molecular mass of ?66,000 and ?44,000 Da) hitherto not known in its entirety. Peptide de novo sequencing and structural elucidation of N-glycopeptides obtained either directly from proteolytic digestion or after zwitterionic hydrophilic interaction liquid chromatography solid phase extraction-based separation were performed by use of nanoelectrospray ionization quadrupole time-of-flight mass spectrometry and low-energy collision-induced dissociation experiments. De novo sequencing provided new insights into the disulfide linkage organization, intersection of subunits and complete N-glycan structures along with site specificities. The primary sequence suggests that the enzyme belongs to glycosyl hydrolase family 38 and the N-glycan sequence analysis revealed high-mannose oligosaccharides, which were found to be heterogeneous with varying number of hexoses viz, Man8-9GlcNAc2 and Glc1Man9GlcNAc2 in an evolutionarily conserved N-glycosylation site. This site with two proximal cysteines is present in all the acidic ?-mannosidases reported so far in eukaryotes. Further, a truncated paucimannose type was identified to be lacking terminal two mannose, Man1(Xyl)GlcNAc2 (Fuc). PMID:24295789

Late Hadean-Eoarchean transitions in crustal evolution from Hf isotopic evidence in the Jack Hills zircons  

NASA Astrophysics Data System (ADS)

The evolution of the Earth's earliest crust remains largely unknown due to the dearth of Hadean (>4 Ga) rocks, with most observational evidence of the planet's first few hundred million years deriving from geochemical studies of 4.4-4.0 Ga detrital zircons from Jack Hills (Narryer Gneiss Complex, Yilgarn craton). Previous Lu-Hf investigations of the zircons have suggested that continental-like (low Lu/Hf) crust formation began by ~4.4-4.5 Ga and may have continued for several hundred million years. The most ancient crust represented in the Jack Hills population was preserved until at least ~4 Ga. However, evidence for the involvement of Hadean materials in later crustal evolution is sparse, and even at Jack Hills the most unradiogenic, ancient materials represented by some Hadean zircons have not been identified in the younger rock and zircon record. We present new Lu-Hf results from <4 Ga Jack Hills zircons that indicate an important transition in Yilgarn crustal evolution between 4.0 and 3.6 Ga. Although Hadean samples are permissive of crustal extraction from the mantle up to ~4 Ga, crust in the Jack Hills source evolves dominantly by internal reworking 4.0-3.8 Ga, and both the most ancient and most juvenile components of the crust are lost from the zircon record after ~4 Ga. New juvenile additions to the crust at ~3.8-3.7 Ga are accompanied by the disappearance of crust with model ages >4.3 Ga. These new data indicate a tectonic regime in the Eoarchean (4.0-3.6 Ga) Yilgarn characterized by internal crustal reworking punctuated by one relatively short juvenile crust extraction event. The coupling in time of juvenile crust formation with the loss of ancient crust is best explained by a mechanism similar to subduction, which accomplishes both processes on the modern Earth. We interpret these data as consistent with the action of destructive plate boundary interactions by Eoarchean times.

Plan for Using Solar-Powered Jack Pumps to Sample Groundwater at the Nevada Test Site  

SciTech Connect

Groundwater is sampled from 39 monitoring wells on the Nevada Test Site (NTS) as part of the Routine Radiological Environmental Monitoring Program. Many of these wells were not designed or constructed for long-term groundwater monitoring. Some have extensive completion zones and others have obstructions such as pumps and tubing. The high-volume submersible pumps in some wells are unsuitable for long-term monitoring and result in large volumes of water that may have to be contained and characterized before subsequent disposition. The configuration of most wells requires sampling stagnant well water with a wireline bailer. Although bailer sampling allows for the collection of depth-discrete samples, the collected samples may not be representative of local groundwater because no well purging is done. Low-maintenance, solar-powered jack pumps will be deployed in nine of these onsite monitoring wells to improve sample quality. These pumps provide the lift capacity to produce groundwater from the deep aquifers encountered in the arid environment of the NTS. The water depths in these wells range from 700 to 2,340 ft below ground surface. The considerable labor and electrical power requirements of electric submersible pumps are eliminated once these pumps are installed. Access tubing will be installed concurrent with the installation of the pump string to provide downhole access for water-level measurements or other wireline instruments. Micro-purge techniques with low pump rates will be used to minimize purge volumes and reduce hydraulic gradients. The set depths of the pumps will be determined by the borehole characteristics and screened interval.

Hafnium isotopes in Jack Hills zircons and the formation of the Hadean crust  

NASA Astrophysics Data System (ADS)

New bulk Hf and Pb isotope data were obtained for 63 leached single zircons from Jack Hills (JH), Western Australia, using solution chemistry and, respectively, MC-ICP MS and ICP-MS. With the exception of one "young" zircon at 3.32 Ga, the remainder of the selected grains were previously dated at > 3.9 Ga by ion-microprobe. This work extends and complements the solution chemistry data of Harrison et al. [Harrison, T.M., Blichert-Toft, J., Müller, W., Albarède, F., Holden, P., Mojzsis, S.J., 2005. Heterogeneous Hadean hafnium: evidence of continental crust at 4.4 to 4.5 Ga. Science 310, 1947-1950.] but uses bulk rather than in situ Pb-Pb ages to interpret the Hf isotope data. This larger data set is used to explore whether the host rocks of the JH zircons formed as a succession of pulses or rather as a single event, and to calculate the age and assess the nature of their crustal protolith. We find that the parent granites of the JH zircons analyzed here formed during a single pulse 4.1 ± 0.1 Ga ago by the remelting of a 4.30-4.36 Ga old protolith. Monte Carlo modeling indicates that the 176Lu/ 177Hf ratios of this material (< 0.01) are unlike the ratios of modern-type oceanic crust and island arc rocks but rather fit a tonalite-trondhjemite-granodiorite (TTG) source. TTGs themselves derived their inordinately enriched character from a basaltic progenitor which corresponds to the missing enriched reservoir identified by the 143Nd- 144Nd, 142Nd- 144Nd, and 176Hf/ 177Hf systematics of Archean rocks. We speculate that crystallization of the magma ocean in the presence of garnet left the upper mantle and an early basaltic crust enriched in incompatible elements. Reaction of this early crust with the overlying hydrosphere and subsequent foundering into the mantle gave rise at ˜ 4.3 Ga to the TTG protolith of the JH granites. Dating the onset of plate tectonics therefore depends on whether TTGs can be considered as subduction zone magmas or not.

Purification of urease from jack bean (Canavalia ensiformis) with copper (II) chelated poly(hydroxyethyl methacrylate-N-methacryloyl-(L)-histidine methyl ester) cryogels.  

PubMed

Jack bean (Canavalia ensiformis) is the source of interesting proteins that contribute to modern biochemistry, and urease is the primary of these proteins. Owing to its role and occurrence in nature, urease has become a part of extensive studies. In this study, jack bean urease (JBU) was purified by immobilized metal affinity chromatography using Cu(2+) chelated poly(hydroxyethyl methacrylate-N-methacryloyl-(L)-histidine methyl ester) [PHEMAH-Cu(2+)]-based cryogels. PHEMAH-Cu(2+) cryogel was synthesized and characterized for swelling degree, morphology (by SEM), N-methacryloyl-(L)-histidine methyl ester and Cu(2+) incorporation (by elemental analysis and atomic absorption spectrophotometry). The binding of JBU to PHEMAH-Cu(2+) cryogel was optimized by examining the effect of pH, flow rate and JBU concentration on binding. The maximal binding of JBU was 23.2 mg/dry gram of adsorbent. The maximal binding of JBU extracted from jack bean meal was 67.8 mg/dry gram of adsorbent. The elution of JBU from cryogel column was accomplished by 1.0 M NaCl in 20 mM phosphate buffer (pH 8.0). Molecular weight and purity of JBU from jack bean meal was estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. It was observed that JBU could be repeatedly bound and eluted from (PHEMAH)-Cu(2+) cryogel with less than 10% loss in column capacity. PMID:23108614

The generalized linear model (GLM) and generalized additive model (GAM) were applied to the standardization of catch per unit effort (CPUE) for Chilean jack mackerel from Chinese factory trawl fishing fleets in the Southeast Pacific Ocean from 2001 to 2010 by removing the operational, environmental, spatial and temporal impacts. A total of 9 factors were selected to build the GLM and GAM, i.e., Year, Month, Vessel, La Niña and El Niño events (ELE), Latitude, Longitude, Sea surface temperature (SST), SST anomaly (SSTA), Nino3.4 index and an interaction term between Longitude and Latitude. The first 5 factors were significant components in the GLM, which in combination explained 27.34% of the total variance in nominal CPUE. In the stepwise GAM, all factors explained 30.78% of the total variance, with Month, Year and Vessel as the main factors influencing CPUE. The higher CPUE occurred during the period April to July at a SST range of 12-15°C and a SSTA range of 0.2-1.0°C. The CPUE was significantly higher in normal years compared with that in La Niña and El Niño years. The abundance of Chilean jack mackerel declined during 2001 and 2010, with an increase in 2007. This work provided the relative abundance index of Chilean jack mackerel for stock assessment by standardizing catch and effort data of Chinese trawl fisheries and examined the influence of temporal, spatial, environmental and fisheries operational factors on Chilean jack mackerel CPUE.

Micron-Scale Correlations Among Ti, P, Ce, and Y in Hadean Jack Hills Zircons  

NASA Astrophysics Data System (ADS)

Detrital zircons and the inclusions found therein are our only mineralogical constraints on geologic events that occurred on the Hadean Earth. These zircons are commonly small (ca. <100 ?m in the longest dimension) and preserve micron to sub-micron chemical zonations indicative of a dynamic petrological history. Trace elements within zircon are of particular interest because concentrations and ratios of these elements can provide information regarding chemical and physical conditions during zircon growth. In this study, we analyzed Hadean-age detrital zircons from Archean metasediment in the Jack Hills (Australia) using the Caltech Microanalysis Center Cameca NanoSIMS 50L. Trace elements analyzed included Ti, P, Ce, and Y. Ti- thermometry [1,2,3] can potentially constrain growth and/or re-equilibration temperatures of zircons; P, Ce, and Y are known to enter the zircon lattice by the coupled xenotime-type substitution mechanism: (Y, REE)3+ + P5+ = Zr4+ + Si4+ [5]. The 89Y/28Si ratio was observed to correlate with, and was used as a proxy for, cathodoluminescence (CL) banding. Growth features manifested in CL (e.g., sector, oscillatory zoning) were observed in all zircons analyzed. CL zones vary from <1 ?m to several microns in width; therefore, the NanoSIMS---with a beam diameter resolved to ca. 250 nm on the sample surface when operating with an O- primary beam---is uniquely suited for this scale of analysis. Regions displaying CL banding were imaged as 20 x 20 ?m areas. All elements were normalized to 28Si; 49Ti/28Si ratios were converted to [Ti] via calibration based on analyses of synthetic, high-Ti zircons (provided by B. Watson) that were independently analyzed on Caltech's JEOL JXA-8200 electron microprobe. We observe three types of relationships between trace element distribution and CL banding in the zircons imaged: 1) strong positive correlations between CL banding, P, Ce, and Ti; 2) subtle positive correlations between CL banding, P, Ce, and Ti; 3) no correlation between minor/trace elements and CL banding. Positive correlations between CL banding, 3+ cations, and [Ti] have previously been reported by Holden et al. [4]. In this study, gradients at least as sharp as a factor of ~3 in [Ti] are observed between adjacent CL bands in the strongly correlated images. These images also have the highest absolute concentrations of trace elements and display both sector and oscillatory zoning in CL. The correlations observed may be due to: temperature-dependent equilibrium partitioning of all trace elements during rapid cycles in growth temperature; episodic diffusion-limited enrichment of incompatible trace elements in the boundary layer melt adjacent to growing crystals; and/or kinetically controlled, non- equilibrium crystal-melt partitioning caused by trace element enrichments in the boundary layer melt surrounding fast-growing grains (e.g., [6]). We will discriminate between these alternatives based on quantitative relationships between relative enrichments of [Ti] and other trace elements. [1]Watson, E.B. & Harrison, T.M.

Search for the origins of the geodynamo: Paleomagnetic studies of rocks and zircon crystals from the Jack Hills, Western Australia  

NASA Astrophysics Data System (ADS)

It is currently unknown when Earth's dynamo magnetic field originated. This timing has major implications for the thermal evolution of the interior, the physics of dynamo action, the surface cosmic ray flux, the evolution of the terrestrial atmosphere, and planetary habitability. Paleomagnetic studies of the oldest known unmetamorphosed rocks indicate that a field with intensity similar to that of the present existed at least 3.5 billion years ago (Ga). One of the very few sample suites predating this time are detrital zircon crystals found in quartz-rich siliciclastic rocks from the Jack Hills of Western Australia. With crystallization ages ranging from 3.0-4.38 Ga, they have the potential to preserve a record of the missing first billion years of Earth's magnetic field history. Over the last fourteen years, we have been studying individual Jack Hills zircon crystals and their host rocks to characterize the nature, age, and intensity of their paleomagnetism. Petrographic and rock magnetic studies suggest the zircons contain inclusions of ferromagnetic iron oxides and sulfides. Using a newly developed ultra-high sensitivity moment magnetometry technique implemented on our superconducting quantum interference device (SQUID) microscope, we have found that many zircons carry an extremely weak natural remanent magnetization (ranging from 5-10x10-14 Am2), essentially making them the most weakly magnetic samples studied in the history of paleomagnetism. They present tremendous analytical challenges associated with magnetic contamination and limitations on magnetic recording properties. We present the first magnetic field paleointensity studies of these zircons. The key unknown is the age and origin of their magnetization. In particular, the identification of >3.9 Ga (Hadean) field records requires at least establishing that the zircons have avoided post-depositional remagnetization. However, there are presently no paleomagnetic data that have confidently established the magnetization history for the Hadean zircon locality (Erawandoo Hill), thought to have been deposited at 2.65-3.05 Ga. To address this gap, we have conducted paleomagnetic conglomerate, baked contact, and fold tests in combination with geochronometry to establish the timing of the metamorphic and alteration events and the peak temperatures experienced by the zircons' host rocks. Although we have found little evidence for remagnetization by recent lightning strikes, most rocks in this area have been pervasively remagnetized to at least 330-530°C, likely from the effects of nearby Mesoproterozoic mafic intrusions. However, localized regions of the Jack Hills may have escaped complete remagnetization. We will discuss the implications of these data for the possibility that magnetization in the detrital zircons predates their deposition.

Metazoan parasites of the jack mackerel Trachurus murphyi (Teleostei, Carangidae) in a latitudinal gradient from South America (Chile and Peru).  

PubMed

The metazoa parasite fauna of the jack mackerel Trachurus murphyi Nichols 1920, obtained from seven ports from a latitudinal gradient of more than 30 degrees (From Paita Peru: 05 degrees 10' S to Talcahuano, Chile 36 degrees 40' S) was quantitatively described. 21 species of metazoan parasites were recorded (Monogenea 4, Digenea 3, Cestoda 5, Acanthocephala 2, Nematoda 4, Copepoda 2, Isopoda 1). Only four parasites (Lernanthropus trachuri, Ceratothoa gaudichaudii, Corynosoma australis, Anisakis simplex) were common to the seven ports. Only twelve species reach prevalence over 5% in at least one port. Main characteristic of the parasite fauna is the sparse of adult helminthes, specifically digenean and the dominance of larval forms, at both qualitative and quantitative levels. There are not evidence of changes in the parasite community along a latitudinal gradient, but at least Anisakis simplex (larvae) shows a trend in both, prevalence and mean intensity, increasing from north to south.

Neoarchean metamorphism recorded in high-precision Sm-Nd isotope systematics of garnets from the Jack Hills (Western Australia)  

NASA Astrophysics Data System (ADS)

Studies of metasedimentary rocks from the Jack Hills, which host Earth's oldest known detrital minerals, have focused on zircon and occasionally monazite or xenotime, but no attention has been directed toward one of the most common mineral markers of metamorphism: garnet. Garnet can provide a record of the post-depositional, prograde metamorphic history of Archean metasedimentary rocks. Additionally, the use of a newly developed detrital garnet dating technique [1,2] may reveal information about pre-depositional metamorphism that could address lingering questions about the nature and timing of Earth's earliest tectonometamorphic events. Here we investigate garnet from the Jack Hills metasedimentary rocks to test whether they record in situ metamorphism or are a detrital relict of even older metamorphic events. We identified garnet in two bulk quartz-pebble conglomerate samples collected from the 'discovery' outcrop at Eranondoo Hill in the Jack Hills of Western Australia. Electron microprobe analyses of polished grains and SEM measurements of unpolished grain surfaces are consistent, revealing garnet composition indicative of a single generation/population of predominantly almandine-spessartine solid solution (~10-35% mole fraction spessartine). Compositional maps of garnet grains reveal little zoning and no discontinuities, most consistent with a single growth event. Dating Jack Hills' garnet via the Sm-Nd system is possible due to continued development of small sample analysis techniques, including running NdO+ TIMS analyses with Ta2O5 activator [3] permitting <50 ppm 2 sigma analytical precision on a 400pg in-house standard and continued improvement in blanks (<15pg full procedural blanks). Additionally, employing a nondestructive chemical prescreening technique (tabletop SEM) allows for grouping of multiple grains based on chemical similarity. Final Nd loads in the 450-750pg range routinely yield dates with precisions <×10Ma for two point isochrons between clean garnet (Sm/Nd ? 1.0) and their leached inclusion populations [2]. Four grouped garnet grain separates from one sample yield preliminary dates of 2703.6×6.0Ma, 2612.4×6.0Ma, 2605.0×5.5Ma, and 2567.3×8.3Ma, while the second sample yielded a date of 2579.6×4.6 Ma (2?). Compositional and geochronologic data indicate likely in situ garnet growth during a late Archean greenschist facies metamorphic event. These dates are generally consistent with published monazite ages placing a metamorphic event at ~ca.2.65Ga [4,5]. It remains possible that an as yet unidentified detrital garnet component is present and may explain some of the scatter in absolute age.

The 'Jack Stone' or 'Mercedes Benz' sign--anew theory to explain the presence of gas within fissures in gallstones.  

PubMed

Gas within clefts of fissures in gallstones is not a very common finding, but when it occurs is, characteristic and indicates the presence of one or more calculi. It closely resembles the appearance of a 'Jack Stone' but has previously been termed the 'Mercedes Benz' sign. Only a few cases have previously been recognised in the U.K. Most reported cases have been associated with biliary colic or cholecystitis. Various theories have been put forward to explain the presence of gas, but the author believes that the gas is released from solution by negative pressure within cholesterol stones undergoing internal fissuring due to their crystalline structure, i.e. the gas is released from solution from the small amount of fluid trapped in the calculus, in the same way that gas may be 'pulled' out of solution in a joint, a degenerate intervertebral disc or the fibro-cartilage of the symphysis pubis.

Health & Safety Executive Impact of changes to T&R 5-5A on jack-up system reliability levels  

E-print Network

The Guideline and Recommended Practice for jack-up site specific assessment contained in theSNAME T&R Bulletin 5-5A attempted, amongst other objectives, to create a unified, industryaccepted practice that could evolve to form the basis for an ISO standard. Technology continues to evolve and several modifications to the document have been proposed which can provide the impetus needed to fully meet such an important goal. The present work aims to develop a robust methodology to provide quantified guidance relating to the impact on reliability of changes to T&R 5-5A being presently considered by the industry. This will facilitate the industry consensus necessary for such changes to be fully incorporated into jack-up site assessment. Phase 1 of the work is covered in this report. A review of previous pushover and reliability analyses is given and areas where modeling improvements are recommended were identified. Factors that affect jack-up system reliability were identified and a premise for performing reliability analyses of jack-ups utilizing state-of-the-art modeling is outlined. Two rig/location cases were selected that were as close to the T&R 5-5A calibration cases as possible and the impact of proposed changes to T&R 5-5A on unity checks was evaluated based on such cases. This report and the work it describes were funded by the Health and Safety Executive (HSE).

Estimates of in situ deformability with an NX borehole jack, Spent Fuel Test - Climax, Nevada test site  

SciTech Connect

A series of borehole modulus measurements was obtained at the Spent Fuel Test - Climax (SFT-C) facility following removal of heat sources and a subsequent 1-year cooling period. A total of 212 measurements were obtained using a standard hardrock NX borehole (Goodman) jack. The results of 64 measurements made at the site before heating were reanalyzed for comparison with the post-heat data. Modulus values were calculated from the straight-line portion of the pressure vs displacement curves. Although the deformation modulus was observed to be highly variable, models were developed to explain much of this variability. Typically, spacial effects, anisotropy, and heating effects were present. The test results indicate that the deformation modulus tended to increase in the pillars between the underground openings where temperatures increased about 10{sup 0}C above the ambient 24{sup 0}C during the SFT-C. Conversely, a decrease in modulus was observed where temperatures were near 60{sup 0}C for a three-year period. In most cases, we found the modulus values to be slightly higher for vertical than for horizontal loading. There was a tendency for the modulus to be lower near excavated openings. While this effect was not ubiquitous, it was statistically significant.

White Anglo-Saxon hopes and black Americans' Atlantic dreams: Jack Johnson and the British boxing colour bar.  

PubMed

This article examines the controversy surrounding Jack Johnson's proposed world heavyweight title fight against the British champion Bombardier Billy Wells in London (1911). In juxtaposing African Americans' often glowing discussions of European tolerance with the actual white resistance the black champion faced in Britain, including the Home Office's eventual prohibition of the match, the article explores the period's transnational discourses of race and citizenship. Indeed, as white sportsmen on both sides of the Atlantic joined together in their search for a "White Hope" to unseat Johnson, the boxing ring became an important cultural arena for interracial debates over the political and social divisions between white citizens and nonwhite subjects. Although African Americans had high hopes for their hero's European sojourn, the British backlash against the Johnson-Wells match underscored the fact that their local experiences of racial oppression were just one facet of a much broader global problem. At the same time, the proposed prizefight also made the specter of interracial conflict in the colonies all the more tangible in the British capital, provoking public discussions about the merits of U.S. racial segregation, along with the need for white Anglo-Saxon solidarity around the world. Thus, this article not only exposes the underlying connections between American Jim Crow and the racialized fault lines of British imperialism, but it also traces the "tense and tender ties" linking U.S. and African American history with the new imperial history and postcolonial studies.

Assessment of possible sources of microbiological contamination and water-quality characteristics of the Jacks Fork, Ozark National Scenic Riverways, Missouri; phase II  

USGS Publications Warehouse

In 1998, an 8-mile reach of the Jacks Fork was included on Missouri?s list of impaired waters as required by Section 303(d) of the Federal Clean Water Act. The identified pollutant on the Jacks Fork was fecal coliform bacteria. Potential sources of fecal contamination to the Jacks Fork include a wastewater treatment plant; campground pit-toilet or septic-system effluent; a large commercial, cross-country horseback trail riding facility; canoeists, boaters, and tubers; and cows.The U.S. Geological Survey, in cooperation with the National Park Service, conducted a study to better understand the extent and sources of microbiological contamination within the Jacks Fork from Alley Spring to the mouth, which includes the 8-mile 303(d) reach. Identification of the sources would provide the National Park Service and the State of Missouri with the information needed to craft a solution of abatement, regulation, prevention, and mitigation with the end result being the removal of the Jacks Fork from the 303(d) list. Fifteen sites were sampled from November 1999 through December 2000. An additional site was sampled one time. Samples were collected mostly during base-flow conditions during a variety of nonrecreational and recreational season river uses. Samples were analyzed for selected fecal indicator bacteria, physical properties, nutrients, and wastewater organic compounds. During the sampling period, the whole-body-contact recreation standard for fecal coliform (200 colonies per 100 milliliters of sample) was exceeded at three sites on August 10, 2000, and also at one site on May 11, June 7, and October 3, 2000. Fecal coliform densities and instantaneous loads generally increased from background concentrations at the Eminence site, peaked about 2 river miles downstream, and then decreased until the most downstream site sampled. Generally, the largest densities and loads at sites downstream from Eminence not related to wet-weather flow were observed during a trail ride held August 6 to12, 2000. A 24-hour sample collection effort was conducted the weekend of July 15 and 16, 2000, to investigate the effect that large numbers of swimmers, canoeists, and tubers had on fecal coliform densities in the Jacks Fork. Five or six samples were collected at six sites between Saturday morning and the following Sunday afternoon. No fecal coliform density at any of the sites sampled exceeded the whole-body-contact recreation standard. Because bacteria survive longer in stream-bed sediments than in water, a source of bacteria in the water column could be from resuspension of accumulated bacteria from streambed sediments. Water and streambed-sediment samples were collected at three sites on August 3, 2000, 1 week before a trail ride and again at three sites on 2 Assessment of Possible Sources of Microbiological Contamination of the Jacks Fork, Missouri?Phase II August 8, 2000, during a trail ride. Results indicate that fecal coliform bacteria densities increased substantially in the streambed sediment and the water column during the trail ride.Sixty-five Escherichia coli isolates obtained from water samples collected at 9 sites and 23 Escherichia coli isolates obtained from stream-bed-sediment samples collected at 5 sites were submitted for ribotyping analysis. Samples were collected in 2000 during a variety of nonrecreational and recreational season river uses, including trail rides, canoeing, tubing, and swimming. Of the 65 isolates from water samples, 40 percent were identified as originating from sewage, 29 percent from horse, 11 percent from cow, and 20 percent from an unknown source. Of the 23 isolates from streambed-sediment samples, 39 percent were identified as originating from sewage, 35 percent from horse, 13 percent from cow, and 13 percent from unknown sources.Analysis of physical property (dissolved oxygen, pH, specific conductance, and temperature) and nutrient (dissolved nitrite plus nitrate and total phosphorus) data

A Homozygous KCNJ10 Mutation in Jack Russell Terriers and Related Breeds with Spinocerebellar Ataxia with Myokymia, Seizures, or Both  

PubMed Central

Background Juvenile-onset spinocerebellar ataxia has been recognized in Jack Russell Terriers and related Russell group terriers (RGTs) for over 40 years. Ataxia occurs with varying combinations of myokymia, seizures, and other signs of neurologic disease. More than 1 form of the disease has been suspected. Hypothesis/Objectives The objective was to identify the mutation causing the spinocerebellar ataxia associated with myokymia, seizures, or both and distinguish the phenotype from other ataxias in the RGTs. Animals DNA samples from 16 RGTs with spinocerebellar ataxia beginning from 2 to 12 months of age, 640 control RGTs, and 383 dogs from 144 other breeds along with the medical records of affected dogs were studied. Methods This case-control study compared the frequencies of a KCNJ10 allele in RGTs with spinocerebellar ataxia versus control RGTs. This allele was identified in a whole-genome sequence of a single RGT with spinocerebellar ataxia and myokymia by comparison to whole-genome sequences from 81 other canids that were normal or had other diseases. Results A missense mutation in the gene coding for the inwardly rectifying potassium channel Kir4.1 (KCNJ10:c.627C>G) was significantly (P < .001) associated with the disease. Dogs homozygous for the mutant allele all had spinocerebellar ataxia with varying combinations of myokymia and seizures. Conclusions and Clinical Importance Identification of the KCNJ10 mutation in dogs with spinocerebellar ataxia with myokymia, seizures, or both clarifies the multiple forms of ataxia seen in these breeds and provides a DNA test to identify carriers.

Effects of NaCl on responses of ectomycorrhizal black spruce (Picea mariana), white spruce (Picea glauca) and jack pine (Pinus banksiana) to fluoride.  

PubMed

Black spruce (Picea mariana), white spruce (Picea glauca) and jack pine (Pinus banksiana) were inoculated with Suillus tomentosus and subjected to potassium fluoride (1 mM KF and 5 mM KF) in the presence and absence of 60 mM NaCl. The NaCl and KF treatments reduced total dry weights in jack pine and black spruce seedlings, but they did not affect total dry weights in white spruce seedlings. The addition of 60 mM NaCl to KF treatment solutions alleviated fluoride-induced needle injury in ectomycorrhizal (ECM) black spruce and white spruce, but had little effect in jack pine seedlings. Both KF and 60 mM NaCl treatments reduced E values compared with non-treated control seedlings. However, with the exception of small reductions of K(r) by NaCl treatments in black spruce, the applied KF and NaCl treatments had little effect on K(r) in ECM plants. Chloride tissue concentrations in NaCl-treated plants were not affected by the presence of KF in treatment solutions. However, shoot F concentrations in ECM black spruce and white spruce treated with 5 mM KF + 60 mM NaCl were significantly reduced compared with the 5 mM KF treatment. The results point to a possible competitive inhibition of F transport by Cl. We also suggest that the possibility that aquaporins may be involved in the transmembrane transport of F should be further investigated. PMID:19121099

Variability in Light Use Efficiency With Changes in Vegetation Structure and Understory, Using a Temporally Changing Flux Footprint at the BERMS Old Jack Pine Site  

NASA Astrophysics Data System (ADS)

Satellite remote sensing algorithms of vegetation gross primary productivity (GPP) often include a light use efficiency (LUE) term that varies depending on meteorological constraints and biome type. LUE is defined as the carbon fixed per mole of photosynthetically active radiation (PAR) absorbed by the canopy (APAR). LUE estimated using GPP from eddy covariance data is complex and changes over short time periods as the available resources (soil moisture, light, temperature, and nitrogen) vary. An understanding of the variability in LUE will improve local to regional estimates of GPP within complex vegetated land cover types using the variety of remote sensing technologies now available. This study examines variability in LUE and GPP at a mature jack pine site within the Fluxnet-Canada BERMS (Boreal Ecosystem Research and Monitoring Sites) study area using a flux footprint model (Kljun et al. 2004) and airborne lidar data (e.g. Chasmer et al. 2006). Three separate weeks of high frequency eddy covariance data are analyzed for June, July, and August 2002 to capture changes in photosynthesis and carbon uptake through the growing season with variations in precipitation and soil moisture. Footprint estimates are derived in half-hourly resolution to provide information on the spatial and temporal variation of the sources of measured C-fluxes. Airborne lidar directly samples ground topography and vegetation structure (i.e., canopy and understory height, gaps between trees, base of canopy), and may provide information on soil moisture and drainage at the ground surface via absorbed and reflected laser pulse energy. Two questions will be addressed specific to net ecosystem productivity (NEP) of the site as a whole, including parts of the ecosystem that may not be properly represented using eddy covariance techniques. These are: 1. How does C uptake and respiration spatially and temporally vary across the jack pine site? 2. How do vegetation characteristics vary with differences in C uptake and LUE? Preliminary results of this study show definite spatial variability in the structural characteristics of jack pine trees within the site average flux footprint, especially related to the occurrence of an alder understory. Jack pine trees tend to be taller, with greater leaf area and greater depth of canopy in areas where alders are prevalent. It is hypothesized that areas that have been classified with taller trees and an alder understory will sequester more carbon than areas that do not contain alder understory. Results are validated using eight surveyed field validation and leaf area index plots as well as an additional 64 plots of understory characteristics and foliage gap fraction.

Helminths of sympatric black-tailed jack rabbits (Lepus californicus) and desert cottontails (Sylvilagus audubonii) from the high plains of eastern New Mexico.  

PubMed

Thirty-five desert cottontails (Sylvilagus audubonii) and 35 black-tailed jack rabbits (Lepus californicus), occurring sympatrically near the Clovis-Portales area of eastern New Mexico were infected with four species of Eucestoda (adults of Raillietina salmoni and Raillietina selfi, larvae of Taenia pisiformis and Taenia serialis). Raillietina salmoni and T. pisiformis more commonly infected S. audubonii. Raillietina selfi was found in near equal prevalence in both host species. Taenia serialis was recovered only from L. californicus. Thus, three of the four helminth species were shared by both lagomorphs (Jaccard's coefficient = 75). Female hosts were most heavily infected with R. selfi and Taenia serialis. PMID:3373649

Ectoparasites of sympatric cottontails (Sylvilagus audubonii Nelson) and jack rabbits (Lepus californicus Mearns) from the high plains of eastern New Mexico.  

PubMed

Eight species of ectoparasites were recovered from 35 Sylvilagus audubonii and 35 Lepus californicus occurring sympatrically near the Clovis-Portales area of eastern New Mexico. Recovered were Anoplura (Haemodipsus setoni), Diptera (Cuterebra lepusculi and Cuterebra ruficrus), Siphonaptera (Echidnophaga gallinacea and Euhoplopsyllus glacialis), and Acari (Ornithodoros parkeri, Dermacentor parumapertus, and Haemaphysalis leporispalustris). Jaccard's index showed a 50% ectoparasitic overlap with H. setoni, E. glacialis, D. parumapertus, and H. leporispalustris present on both host species. Cuterebra lepusculi, E. gallinacea, and Ornithodoros parkeri were taken only from S. audubonii, whereas C. ruficrus occurred only on jack rabbits. Euhoplopsyllus glacialis was the only species to demonstrate a preference for sex of host, occurring more abundantly on females. PMID:3418460

Geohydrological feasibility study of the Black Warrior Basin for the potential applicability of Jack W. McIntyre`s patented process  

SciTech Connect

Geraghty & Miller, Inc. of Midland, Texas conducted geological and hydrological feasibility studies of the potential applicability of Jack W. Mclntyre`s patented process for the recovery of natural gas from coalbed/sand formations in the Black Warrior Basin of Mississippi and Alabama through literature surveys. Methane gas from coalbeds in the Black Warrior Basin is confined to the coal fields of northern Alabama. Produced water from degasification of coalbeds is currently disposed by surface discharge. Treatment prior to discharge consists of short-term storage and in-stream dilution. Mr. Mclntyre`s process appears to be applicable to the Black Warrior Basin and could provide an environmentally sound alternative for produced water production.

Effects of Concanavalin A, fed as a constituent of Jack bean (Canavalia ensiformis L.) seeds, on the humoral immune response and performance of broiler chickens.  

PubMed

An experiment was conducted to investigate the effects of the lectin, Concanavalin A (Con A), contained in raw Jack bean (JB) (Canavalia ensiformis, L.) seeds on the immunological response of broilers. A maize-soybean meal basal diet was prepared to which either 2.5, 5, or 10% of ground raw Jack bean (RJB) seeds was added. The RJB seeds contained 24 g Con A/kg on a dry matter basis, as measured by rocket immunoelectrophoresis. Similar diets were prepared by using the same levels of JB after toasting at 190 C for 16 min. In addition, the basal diet was pair-fed to groups of chicks at the level of feed intake of chicks fed the 10% RJB diet. Each diet was fed to six groups of six chicks for 6 wk. At 5 wk, 15 of chicks from each diet were immunized against Brucella abortus (BA) and the anti-BA antibody titers were determined 1 wk later by ELISA. Antibody production against Con A was also measured by the same method. Binding of Con A to intestinal villi and subsequent endocytosis were confirmed by microscopic examination using a specific peroxidase-antiperoxidase-staining technique. Performance was recorded weekly. Feed intake and weight gain were reduced (P < 0.05) only by the diet containing 10% RJB, indicating that broiler chicks can tolerate daily intakes of 100 mg of Con A over 6 wk without affecting growth. Toasted JB diets supported adequate chick performance. The antibody response to BA did not differ with dietary treatment. Serum from chicks fed raw JB also contained antibodies against Con A. The bursa of Fabricius, thymus, spleen, and pancreas dry weights, as a percentage of dry body weight, were not affected by the experimental diets. The data indicated that Con A binds to the cells of the gastrointestinal tract, passes into the general circulation and, eventually, elicits an immunological response without affecting the production of antibodies to BA.

Geohydrologic Investigations and Landscape Characteristics of Areas Contributing Water to Springs, the Current River, and Jacks Fork, Ozark National Scenic Riverways, Missouri  

USGS Publications Warehouse

The Ozark National Scenic Riverways (ONSR) is a narrow corridor that stretches for approximately 134 miles along the Current River and Jacks Fork in southern Missouri. Most of the water flowing in the Current River and Jacks Fork is discharged to the rivers from springs within the ONSR, and most of the recharge area of these springs is outside the ONSR. This report describes geohydrologic investigations and landscape characteristics of areas contributing water to springs and the Current River and Jacks Fork in the ONSR. The potentiometric-surface map of the study area for 2000-07 shows that the groundwater divide extends beyond the surface-water divide in some places, notably along Logan Creek and the northeastern part of the study area, indicating interbasin transfer of groundwater between surface-water basins. A low hydraulic gradient occurs in much of the upland area west of the Current River associated with areas of high sinkhole density, which indicates the presence of a network of subsurface karst conduits. The results of a low base-flow seepage run indicate that most of the discharge in the Current River and Jacks Fork was from identified springs, and a smaller amount was from tributaries whose discharge probably originated as spring discharge, or from springs or diffuse groundwater discharge in the streambed. Results of a temperature profile conducted on an 85-mile reach of the Current River indicate that the lowest average temperatures were within or downstream from inflows of springs. A mass-balance on heat calculation of the discharge of Bass Rock Spring, a previously undescribed spring, resulted in an estimated discharge of 34.1 cubic feet per second (ft3/s), making it the sixth largest spring in the Current River Basin. The 13 springs in the study area for which recharge areas have been estimated accounted for 82 percent (867 ft3/s of 1,060 ft3/s) of the discharge of the Current River at Big Spring during the 2006 seepage run. Including discharge from other springs, the cumulative discharge from springs was over 90 percent of the river discharge at most of the spring locations, and was 92 percent at Big Spring and at the lower end of the ONSR. The discharge from the 1.9-mile long Pulltite Springs Complex measured in the 2006 seepage run was 88 ft3/s. Most of this (77 ft3/s) was from the first approximately 0.25 mi of the Pulltite Springs Complex. It has been estimated that the annual mean discharge from the Current River Springs Complex is 125 ft3/s, based on an apparent discharge of 50 ft3/s during a 1966 U.S. Geological Survey seepage run. However, a reinterpretation of the 1966 seepage run data shows that the discharge from the Current River Springs Complex instead was about 12.6 ft3/s, and the annual mean discharge was estimated to be 32 ft3/s, substantially less than 125 ft3/s. The 2006 seepage run showed a gain of only 12 ft3/s from the combined Round Spring and Current River Springs Complex from the mouth of Sinking Creek to 0.7 mi upstream from Root Hollow. The 2006 temperature profile measurements did not indicate any influx of spring discharge throughout the length of the Current River Springs Complex. The spring recharge areas with the largest number of identified sinkholes are Big Spring, Alley Spring, and Welch Spring. The spring recharge areas with the largest number of sinkholes per square mile of recharge area are Alley Spring, Blue Spring (Jacks Fork), Welch Spring, and Round Spring and the Current River Springs Complex. Using the currently known locations of losing streams, the Big Spring recharge area has the largest number of miles of losing stream, and the Bass Rock Spring recharge area has the largest number of miles of losing stream per unit recharge area. The spring recharge areas with the most open land and the least forested land per unit recharge area are Blue Spring (Jacks Fork), Welch Spring, Montauk Springs, and Alley Spring. The spring recharge areas with the least amount

Geohydrologic feasibility study of the Powder River Basin for the potential application of a production process patented by Jack W. McIntyre  

SciTech Connect

Geraghty & Miller, Inc. of Midland, Texas conducted geologic and hydrologic feasibility studies of the potential applicability of a patented (US Patent Office No. 4,766,957) process developed by Jack W. McIntyre for the recovery of natural gas from coalbed/sand formations in the Powder River Basin. General research, based on a review of published literature from both private and public sources, indicates that the shallow, thick subbituminous coal seams found in the Powder River Basin exhibit significant potential for the application of this patented process. These coal deposits can be characterized, on the basis of established coalbed methane production, as being highly water productive. The desorption and economic recovery of coalbed methane, widely believed to be biogenic in origin, from these low-grade deposits will require the subsequent dewatering of these geologic formations. The patented process, developed by Mr. McIntyre and described in the compendium of this study, may offer a cost-effective means of methane recovery and downhole disposal of produced groundwaters.

Cratoxylum formosum (Jack) Dyer ssp. pruniflorum (Kurz) Gogel. (Hóng yá mù) extract induces apoptosis in human hepatocellular carcinoma HepG2 cells through caspase-dependent pathways  

PubMed Central

Background Cratoxylum formosum (Jack) Dyer ssp. pruniflorum (Kurz) Gogel. (Hóng yá mù) (CF) has been used for treatment of fever, cough, and peptic ulcer. Previously, a 50% ethanol-water extract from twigs of CF was shown highly selective in cytotoxicity against cancer cells. This study aims to investigate the molecular mechanisms underlying the apoptosis-inducing effect of CF. Methods The cytotoxicity of CF was evaluated in the human hepatocellular carcinoma (HCC) HepG2 cell line in comparison with a non-cancerous African green monkey kidney epithelial cell line (Vero) by a neutral red assay. The apoptosis induction mechanisms were investigated through nuclear morphological changes, DNA fragmentation, mitochondrial membrane potential alterations, and caspase enzyme activities. Results CF selectively induced HepG2 cell death compared with non-cancerous Vero cells. A 1.5-fold higher apoptotic effect compared with melphalan was induced by 120 ?g/mL of the 50% ethanol-water extract of CF. The apoptotic cell death in HepG2 cells occurred via extrinsic and intrinsic caspase-dependent pathways in dose- and time-dependent manners by significantly increasing the activities of caspase 3/7, 8, and 9, decreasing the mitochondrial membrane potential, and causing apoptotic body formation and DNA fragmentation. Conclusions CF extract induced a caspase-dependent apoptosis in HepG2 cells. PMID:24708784

Geohydrologic feasibility study of the Northern and Central Appalachian basin areas for the potential application of a production process patented by Jack W. McIntyre  

SciTech Connect

Geraghty & Miller, Inc. of Midland, Texas conducted geologic and hydrologic feasibility studies of the potential applicability of a patented (US Patent Office No. 4,766,957) process developed by Jack W. McIntyre for the recovery of natural gas from coalbed/sand formations in the Northern and Central Appalachian basin areas. General research, based on a review of published literature from both public and private sources, indicates that the generally thin, but numerous coalbeds found in the greater Appalachian Basin area do exhibit some potential for the application of this patented process. Estimates of total gas reserves in-place (Gas Research Institute, July 1991) for coalbeds in the Central and Northern Appalachian Basin areas are 5 trillion cubic feet (TCF) and 61 TCF respectively. Produced waters associated with coal deposits in the greater Appalachian Basin area can be characterized on the basis of established but limited production of coalbed methane. Central Appalachian coals generally produce small quantities of water (less than 50 barrels of water per day for the average producing well) which is high in total dissolved solids (TDS), greater than 30,000 parts per million (ppM). The chemical quality of water produced from these coal seams represents a significant disposal challenge to the operators of methane-producing wells in the Central Appalachian Basin. By contrast, water associated with the production of coalbed methane in the Northern Appalachian Basin is generally fair to good quality, and daily production volumes are low. However, the relatively slow desorption of methane gas from Northern Appalachian coals may result in a greater net volume of produced water over the economic life of the well. The well operator must respond to long-term disposal needs.

PubMed

Cardicola Short, 1953 is a genus of the Aporocotylidae Odhner, 1912 (Digenea), with 25 currently recognised species described from 32 species of Perciformes and Mugiliformes fishes around the world, including eight species from the Great Barrier Reef. Here, we describe two new species from this region, namely Cardicola beveridgei n. sp. from the ventricle and atrium of the mangrove jack, Lutjanus argentimaculatus (Forsskål) (Perciformes: Lutjanidae), and Cardicola bullardi n. sp. from the ventricle of the Australian spotted mackerel, Scomberomorus munroi Collette & Russo (Perciformes: Scombridae), from off Lizard Island, Queensland, Australia. These two new species are most easily distinguished from the 25 current members of Cardicola in having the combination of i) a spinous oral sucker, ii) an anteriorly intercaecal ovary, iii) a uterus that extends anteriorly from the oötype, iv) the number of spines per ventrolateral transverse row, and in v) body size and the length/width ratio, vi) the oesophagus and caecal length(s) relative to body total length, vii) the length of the posterior caeca relative to the anterior pair, viii) the testis length/width ratio and its total size relative to that of the body, ix) the postovarian field as a percentage of body length, and x) egg size. In addition, C. beveridgei n. sp. is further differentiated by possessing a female genital pore that opens anterodextral to the male pore while C. bullardi n. sp. differs further in possessing a testis that is almost entirely intercaecal and does not extend anteriorly to the level of the intestinal bifurcation. Employing genetic analysis of ITS2 rDNA sequence data, representing these species and a further 13 recognised and three putative species of Cardicola, we were able to unequivocally confirm these specimens as distinct (9-22% different over 420 nucleotide positions). Distance analysis of ITS2 showed that i) species of Cardicola from the Siganidae formed a monophyletic clade, to the exclusion of other Cardicola species reported from the Scombridae, Sparidae, Lutjanidae and Chaetodontidae, ii) a general phylogenetic isolation exists between the species of Cardicola reported from scombrid fishes, and iii) C. beveridgei n. sp. and Cardicola milleri Nolan & Cribb, 2006 from lutjanids and Cardicola chaetodontis Yamaguti, 1970 from chaetodontids are phylogenetically close, despite the evolutionary remoteness between the host groups and their highly disparate biology. Given the likelihood of many additional species being attributed to Cardicola, we predict that continued molecular analyses will indicate that this genus will prove to incorporate a series of radiations in association with particular fish taxa as well as evidence of host-switching. (Nucleotide sequences reported in this paper are available in the GenBank database under accession no. KF752497). PMID:24980892

Jack of all trades: versatile catechol crosslinking mechanisms.  

PubMed

Catechols play an important role in many natural systems. They are known to readily interact with both organic (e.g., amino acids) and inorganic (e.g., metal ions, metal oxides) compounds, thereby providing a powerful system for protein curing. Catechol crosslinked protein networks, such as sclerotized cuticle and byssal threads of the mussel, have been shown to exhibit excellent mechanical properties. A lot of effort has been devoted to mimicking the natural proteins using synthetic catechol-functionalized polymers. Despite the success in developing catechol-functionalized materials, the crosslinking chemistry of catechols is still a subject of debate. To develop materials with controlled and superior properties, a clear understanding of the crosslinking mechanism of catechols is of vital importance. This review describes the crosslinking pathways of catechol and derivatives in both natural and synthetic systems. We discuss existing pathways of catechol crosslinking and parameters that affect the catechol chemistry in detail. This overview will point towards a rational direction for further investigation of the complicated catechol chemistry. PMID:25231624

The potential influence of plant-based feed supplements on sperm quantity and quality in livestock: a review.  

PubMed

The reproductive performance of male livestock is of economic importance, and improving semen quantity and quality, especially for artificial insemination, additionally helps to avoid the loss of valuable genotypes. The review focuses on the impact of oxidative stress on sperm production and quality in livestock, and the potential role of plant based anti-oxidants to control this impact. From scientific reports dealing with livestock, the paper compiles evidence on effective dietary measures affecting sperm production and quality. Where little or no data are available on livestock, it refers to sources regarding other mammals, including man. The review concentrates on the use of distinct plants as feed supplements rather than on ways to treat deficiencies and imbalances in energy or macro- and micronutrients. Feeding of maca (Lepidium meyenii) and khat (Catha edulis) has been shown to positively affect sperm production and quality in animals. Some evidence points to favourable effects of leucaena (Leucaena leucocephala and Leucaena pallida), sesbania (Sesbania sesban), pomegranate (Punica granatum), tomato (Solanum lycopersicum) and amaranth (Amaranthus hypochondriacus) as well, but studies are either superficial or results are partially contradictory. Finally, the review considers the potential usefulness of medicinal herbs. The list of such plants includes Chinese herbs such as Lycium barbarum, Astralagus membranaceus, Acanthopanacis senticosi, Magnolia officinalis, Cornus officinalis and Psoralea corylifolia and the Indonesian plant Eurycoma longifolia. European candidate plants are Tribulus terrestris and Pendulum murex. Future research should include the screening of other plants, concentrating on the large number of plants rich in metabolites because of their presumed effectiveness. The modes of action often require clarification for the plants with demonstrated effects. PMID:22575847

Genome Sequence of Aeromonas hydrophila ATCC 7966T: Jack of All Trades?  

PubMed Central

The complete genome of Aeromonas hydrophila ATCC 7966T was sequenced. Aeromonas, a ubiquitous waterborne bacterium, has been placed by the Environmental Protection Agency on the Contaminant Candidate List because of its potential to cause human disease. The 4.7-Mb genome of this emerging pathogen shows a physiologically adroit organism with broad metabolic capabilities and considerable virulence potential. A large array of virulence genes, including some identified in clinical isolates of Aeromonas spp. or Vibrio spp., may confer upon this organism the ability to infect a wide range of hosts. However, two recognized virulence markers, a type III secretion system and a lateral flagellum, that are reported in other A. hydrophila strains are not identified in the sequenced isolate, ATCC 7966T. Given the ubiquity and free-living lifestyle of this organism, there is relatively little evidence of fluidity in terms of mobile elements in the genome of this particular strain. Notable aspects of the metabolic repertoire of A. hydrophila include dissimilatory sulfate reduction and resistance mechanisms (such as thiopurine reductase, arsenate reductase, and phosphonate degradation enzymes) against toxic compounds encountered in polluted waters. These enzymes may have bioremediative as well as industrial potential. Thus, the A. hydrophila genome sequence provides valuable insights into its ability to flourish in both aquatic and host environments. PMID:16980456

Jack-of-all-trades: phenotypic plasticity facilitates the invasion of an alien slug species  

PubMed Central

Invasive alien species might benefit from phenotypic plasticity by being able to (i) maintain fitness in stressful environments (‘robust’), (ii) increase fitness in favourable environments (‘opportunistic’), or (iii) combine both abilities (‘robust and opportunistic’). Here, we applied this framework, for the first time, to an animal, the invasive slug, Arion lusitanicus, and tested (i) whether it has a more adaptive phenotypic plasticity compared with a congeneric native slug, Arion fuscus, and (ii) whether it is robust, opportunistic or both. During one year, we exposed specimens of both species to a range of temperatures along an altitudinal gradient (700–2400 m a.s.l.) and to high and low food levels, and we compared the responsiveness of two fitness traits: survival and egg production. During summer, the invasive species had a more adaptive phenotypic plasticity, and at high temperatures and low food levels, it survived better and produced more eggs than A. fuscus, representing the robust phenotype. During winter, A. lusitanicus displayed a less adaptive phenotype than A. fuscus. We show that the framework developed for plants is also very useful for a better mechanistic understanding of animal invasions. Warmer summers and milder winters might lead to an expansion of this invasive species to higher altitudes and enhance its spread in the lowlands, supporting the concern that global climate change will increase biological invasions.

Temporal Variation of the Mating System in a Natural Population of Jack Pine  

PubMed Central

Mating system parameters of a northern conifer, Pinus banksiana Lamb., were estimated from allozyme polymorphisms. Seeds analyzed were obtained from serotinous cones of 30 individuals and represented four independent fertilizations in 1975, 1976, 1977 and 1978. Results indicated that a mixed mating system model, with a mean effective outcrossing rate of 88 ± 0.047%, described the mating system of this stand. However, there was an approximately linear increase in the apparent selfing rate from the oldest (1975) to the newest (1978) crop. Two hypotheses could account for these observations. First, there may have been changes in the mating system during the 4-yr period, but linearity of the differences observed in this study may have been due to chance. These changes were, however, independent of the variability of the observed pollen pool. This indicated that they were not a result of different proportions of outcrossed zygotes directly observed. Second, there could have been a more or less constant amount of selfing, followed by a differential loss of viability of selfed and outcrossed zygotes during the period of storage in the cones. Under this hypothesis, selfed zygotes are at a selective disadvantage relative to outcrossed zygotes. No differences in the mating system could be demonstrated among the three crown strata of this stand. There was significant interlocus heterogeneity in the filial generation genotypic distributions and in the estimated outcrossing rates, reflecting the complex nature of forces that can affect single-locus estimates. There was evidence of some additional inbreeding, possibly due to family structures in the stand; however, this was a minor component of the total inbreeding. PMID:17246256

Jack-of-all-trades master of all? Snake vertebrae have a generalist inner organization.  

PubMed

Snakes are a very speciose group of squamates that adapted to various habitats and ecological niches. Their ecological diversity is of particular interest and functional demands associated with their various styles of locomotion are expected to result in anatomical specializations. In order to explore the potential adaptation of snakes to their environment we here analyze variation in vertebral structure at the microanatomical level in species with different locomotor adaptations. Vertebrae, being a major element of the snake body, are expected to display adaptations to the physical constraints associated with the different locomotor modes and environments. Our results revealed a rather homogenous vertebral microanatomy in contrast to what has been observed for other squamates and amniotes more generally. We here suggest that the near-absence of microanatomical specializations in snake vertebrae might be correlated to their rather homogeneous overall morphology and reduced range of morphological diversity, as compared to lizards. Thus, snakes appear to retain a generalist inner morphology that allows them to move efficiently in different environments. Only a few ecologically highly specialized taxa appear to display some microanatomical specializations that remain to be studied in greater detail. PMID:24113831

Influence of carbon to nitrogen ratios on soybean somatic embryo (cv. Jack) growth and composition.  

PubMed

Soybean [Glycine max (L.) Merr.] seed are valued for their protein and oil content. Soybean somatic embryos cultured in Soybean Histodifferentiation and Maturation (SHaM) medium were examined for their suitability as a model system for developing an understanding of assimilate partitioning and metabolic control points for protein and oil biosynthesis in soybean seed. This report describes the growth dynamics and compositional changes of SHaM embryos in response to change in the carbon to nitrogen ratio of the medium. It was postulated that at media compositions that were sufficient to support maximal growth rates, changes in the C:N ratio are likely to influence the partitioning of resources between the various storage products, especially protein and oil. As postulated, at steady-state growth rates, embryo protein content was strongly correlated with decreasing C:N ratios and increasing glutamine consumption rates. However, oil content remained relatively unchanged across the C:N ratio range tested, and resources were instead directed towards the starch and residual biomass (estimated by mass balance) pools in response to increasing C:N ratios. Protein and oil were inversely related only at concentrations of sucrose in the medium <88 mM, where carbon limited growth and no starch was found to accumulate in the tissues. These observations and the high reproducibility in the data indicate that SHaM embryos are an ideal model system for the application of metabolic flux analysis studies designed to test hypotheses regarding assimilate partitioning in developing soybean seeds.

Why does Jack, and not Jill, break his crown? Sex disparity in brain tumors  

PubMed Central

It is often reported that brain tumors occur more frequently in males, and that males suffer a worse outcome from brain tumors than females. If correct, these observations suggest that sex plays a fundamental role in brain tumor biology. The following review of the literature regarding primary and metastatic brain tumors, reveals that brain tumors do occur more frequently in males compared to females regardless of age, tumor histology, or region of the world. Sexually dimorphic mechanisms that might control tumor cell biology, as well as immune and brain microenvironmental responses to cancer, are explored as the basis for this sex disparity. Elucidating the mechanisms by which sex chromosomes and sex hormones impact on brain tumorigenesis and progression will advance our understanding of basic cancer biology and is likely to be essential for optimizing the care of brain tumor patients.

Osmotolerance in the Cryptophyceae: jacks-of-all-trades in the Chroomonas Clade.  

PubMed

No detailed studies have been performed to date on osmotolerance in cryptophytes, although one species, Chroomonas africana, had previously been reported to grow in freshwater as well as seawater. This study focused on osmotolerance in Chroomonas. Growth at different osmolalities and parameters of contractile vacuole function were examined and compared across a high-resolution phylogeny. Two evolutionary lineages in the Chroomonas clade proved to be euryhaline. Ranges of osmotolerance depended not only on osmolality, but also on culture medium. All cryptophytes contained contractile vacuoles. In the euryhaline strain CCAP 978/08 contractile vacuoles could be observed even at an osmolality beyond that of seawater. In addition the cells accumulated floridoside, an osmoprotectant likely originating from the red algal carbohydrate metabolism of the complex rhodoplast. Further evidence for functional contractile vacuoles also in marine cryptophytes was provided by identification of contractile vacuole-specific genes in the genome of Guillardia theta. PMID:24568876

The present work reports cerebellar degeneration in cattle associated with the ingestion of Solanum subinerme in northern Brazil. The main clinical signs were periodic crises with loss of balance, falls, opisthotonus, and nystagmus. The histological lesions consisted of diffuse vacuolation of the perikaryon of the Purkinje neurons, followed by the loss of these cells and their substitution by Bergman glia. It is concluded that S. subinerme is another species of Solanum that causes cerebellar degeneration in cattle. PMID:24561122

New Analyses of Diverse Hadean Zircon Inclusions from Jack Hills, Western Australia  

NASA Technical Reports Server (NTRS)

The geological record is the only direct source of information regarding physical/chemical processes that may have ultimately been responsible for the origin of life. Known terrestrial rocks have ages that span from present day to approx. 4.0 Ga. This leaves a time gap of more than 500 Myr between lunar formation, and preservation of the oldest terrestrial crust. What were planetary conditions like wherein the prebiotic chemistry leading to life took place? The recent discovery of up to 4.37 Ga detrital zircons from Western Australia represents the only tangible record of the time period termed the Hadean Eon (4.5-4.0 Ga). Knowledge of the paragenesis of the oldest zircons potentially contributes information regarding the origin of the atmosphere, hydrosphere, continental lithosphere and the potential for life on the Hadean Earth.

Differential niche modification by males and females of a dioecious herb: extending the Jack Sprat effect.  

PubMed

Males and females of dioecious plants often differ in morphological, physiological and life-history traits, probably as a result of their different requirements for reproduction. We found that the growth and reproductive effort of individuals of the dioecious herb Mercurialis annua depended on whether males or females had been growing in the soil previously. This suggests that males and females of M. annua differentially modify the soil in which they are growing. Our study indicates that sexual dimorphism in dioecious plants can give rise to increased environmental heterogeneity as a consequence of sex-specific niche modification. PMID:20825527

Light exposure during storage preserving soluble sugar and l-ascorbic acid content of minimally processed romaine lettuce (Lactuca sativa L.var. longifolia).  

PubMed

Minimally processed romaine lettuce (MPRL) leaves were stored in light condition (2500lux) or darkness at 4°C for 7d. Light exposure significantly delayed the degradation of chlorophyll and decrease of glucose, reducing sugar, and sucrose content, and thus preserved more total soluble solid (TSS) content at the end of storage in comparison with darkness. While, it did not influenced starch content that progressively decreased over time. The l-ascorbic acid (AA) accumulated in light-stored leaves, but deteriorated in dark-stored leaves during storage. The dehydroascorbic acid (DHA) increased in all leaves stored in both light and dark condition, of which light condition resulted in less DHA than darkness. In addition, the fresh weight loss and dry matter significantly increased and these increases were accelerated by light exposure. Conclusively, light exposure in applied intensity effectively alleviated MPRL quality deterioration by delaying the decreases of pigments, soluble sugar, TSS content and accumulating AA.

Discovery of potential anti-infectives against Staphylococcus aureus using a Caenorhabditis elegans infection model  

PubMed Central

Background The limited antibiotic options for effective control of methicillin-resistant Staphylococcus aureus infections has led to calls for new therapeutic approaches to combat this human pathogen. An alternative approach to control MRSA is through the use of anti-infective agents that selectively disrupt virulence-mediated pathways without affecting microbial cell viability or by modulating the host natural immune defenses to combat the pathogen. Methods We established a C. elegans – S. aureus liquid-based assay to screen for potential anti-infectives against S. aureus. The assay was utilized to screen 37 natural extracts and 29 synthetic compounds for the ability to extend the lifespan of infected nematodes. Disc diffusion and MIC microdilution tests were used to evaluate the anti-microbial properties of these natural extracts and synthetic compounds whilst in vivo bacterial CFU within the C. elegans gut were also enumerated. Results We screened a total of 37 natural extracts and 29 synthetic compounds for anti-infective properties. The screen successfully revealed 14 natural extracts from six plants (Nypa fruticans, Swietenia macrophylla, Curcuma longa, Eurycoma longifolia, Orthosiphon stamineus and Silybum eburneum) and one marine sample (Faunus ater) that improved the survival of S. aureus-infected worms by at least 2.8-fold as well as 14 synthetic compounds that prolonged the survival of S. aureus-infected nematodes by 4-fold or greater. An anti-microbial screen of all positive hits demonstrated that 8/28 hits had no effect on S. aureus growth. Of these 8 candidates, 5 of them also protected the worms from MRSA infection. We also noted that worms exposed to N. fruticans root and O. stamineus leaf extracts showed reduced intestinal colonization by live S. aureus. This suggests that these extracts could possibly activate host immunity to eliminate the bacteria or interfere with factor/s that prevents pathogen accumulation. Conclusion We have successfully demonstrated the utility of this liquid-based screen to identify anti-infective substances that prolong S. aureus-infected host survival without affecting bacterial cell viability.

With a bloody union jack on top: The first generation British atomic deterrent. Master`s thesis  

SciTech Connect

Britain constructed an atomic deterrent to influence both the United States and Soviet Union. The process of research and development was both long and difficult. The atomic bomb, first tested in 1952, was a remarkable success. By comparison, the delivery device, the V-bomber, was a failure. While the aircraft produced were excellent, they were deployed too late in too few numbers to be effective in an independent role. Only as part of a larger offensive with the Strategic Air Command could they make a valuable contribution. However, the program`s military failure was offset by its political success. Reopened atomic relations with the United States strengthened British security by providing London with the most modern nuclear weapons and delivery systems.

Jack of All Trades, Master of All: A Positive Association between Habitat Niche Breadth and Foraging Performance in Pit-Building Antlion Larvae  

PubMed Central

Species utilizing a wide range of resources are intuitively expected to be less efficient in exploiting each resource type compared to species which have developed an optimal phenotype for utilizing only one or a few resources. We report here the results of an empirical study whose aim was to test for a negative association between habitat niche breadth and foraging performance. As a model system to address this question, we used two highly abundant species of pit-building antlions varying in their habitat niche breadth: the habitat generalist Myrmeleon hyalinus, which inhabits a variety of soil types but occurs mainly in sandy soils, and the habitat specialist Cueta lineosa, which is restricted to light soils such as loess. Both species were able to discriminate between the two soils, with each showing a distinct and higher preference to the soil type providing higher prey capture success and characterizing its primary habitat-of-origin. As expected, only small differences in the foraging performances of the habitat generalist were evident between the two soils, while the performance of the habitat specialist was markedly reduced in the alternative sandy soil. Remarkably, in both soil types, the habitat generalist constructed pits and responded to prey faster than the habitat specialist, at least under the temperature range of this study. Furthermore, prey capture success of the habitat generalist was higher than that of the habitat specialist irrespective of the soil type or prey ant species encountered, implying a positive association between habitat niche-breadth and foraging performance. Alternatively, C. lineosa specialization to light soils does not necessarily confer upon its superiority in utilizing such habitats. We thus suggest that habitat specialization in C. lineosa is either an evolutionary dead-end, or, more likely, that this species' superiority in light soils can only be evident when considering additional niche axes.

In an in experimental investigation of local recovery factors for a blade having a pressure distribution similar to that of a typical reaction-type turbine blade, it a was found that the recovery factors were essentially independent of Mach number, Reynolds number, pressure gradient, and position on the blade surface except for regions where the boundary layer was probably in the transition range from laminar to turbulent. The recommended value of local subsonic recovery factor for use in calculating the effective gas temperature for gas turbine blades was 0.89.

Effect of Post-Thaw Addition of Seminal Plasma on Motility, Viability and Chromatin Integrity of Cryopreserved Donkey Jack (Equus asinus) Spermatozoa.  

PubMed

Pregnancy rates in donkeys after artificial insemination with cryopreserved semen are still low, compared to the horse species. Addition of autologous seminal plasma to frozen-thawed semen appeared to improve pregnancy rates. The aims of this study were to evaluate (1) sperm motility and plasma membrane integrity after thawing (T0) and after one and 2 h (T1 and T2) of post-thaw incubation in either 0% (SP0) or 70% (SP70) autologous seminal plasma and (2) sperm motility, plasma membrane integrity and DNA quality (%COMP-?t) after thawing (T0) and after 2 and 4 h (T2 and T4) of post-thaw incubation in either 0% (SP0), 5% (SP5) or 20% (SP20) homologous seminal plasma. In experiment 1, seminal plasma decreased total and progressive sperm motility and plasma membrane intact spermatozoa immediately after dilution and at all following time points (p < 0.05). In experiment 2, total and progressive motility did not differ between treatments immediately after dilution and between SP0 and SP5 at T2, while they were lower in both SP5 and SP20 than in SP0 at T4. Plasma membrane intact sperm cells did not differ between SP0 and SP5 and were lower in SP20 at all time points. DNA quality was not affected by treatment immediately after dilution and was significantly worse for SP20 after 4 h of incubation (p < 0.05). The post-thaw addition of seminal plasma at the tested concentrations did not improve donkey frozen semen characteristics in vitro over time. PMID:25256158

The origin of the approximate 24-hour urine sampling protocol used at Hanford for routine bioassay is attributed to an informal study done in the mid-1940s. While the actual data were never published and have been lost, anecdotal recollections by staff involved in the initial bioassay program design and administration suggest that the sampling protocol had a solid scientific basis. Numerous alternate methods for normalizing partial day samples to represent a total 24-hour collection have since been proposed and used, but no one method is obviously preferred.

The jack of all trades is master of none: a pathogen's ability to infect a greater number of host genotypes comes at a cost of delayed reproduction.  

PubMed

A trade-off between a pathogen's ability to infect many hosts and its reproductive capacity on each host genotype is predicted to limit the evolution of an expanded host range, yet few empirical results provide evidence for the magnitude of such trade-offs. Here, we test the hypothesis for a trade-off between the number of host genotypes that a fungal pathogen can infect (host genotype range) and its reproductive capacity on susceptible plant hosts. We used strains of the oat crown rust fungus that carried widely varying numbers of virulence (avr) alleles known to determine host genotype range. We quantified total spore production and the expression of four pathogen life-history stages: infection efficiency, time until reproduction, pustule size, and spore production per pustule. In support of the trade-off hypothesis, we found that virulence level, the number of avr alleles per pathogen strain, was correlated with significant delays in the onset of reproduction and with smaller pustule sizes. Modeling from our results, we conclude that trade-offs have the capacity to constrain the evolution of host genotype range in local populations. In contrast, long-term trends in virulence level suggest that the continued deployment of resistant host lines over wide regions of the United States has generated selection for increased host genotype range.

Roles of lineage sorting and phylogenetic relationship in the genetic diversity at the self-incompatibility locus of Solanaceae.  

PubMed

Allelic polymorphism at the S locus that determines the gametophytic self-incompatibility (GSI) system in the pistil predates speciation. Understanding the evolution of a GSI system therefore requires knowledge of how lineage sorting and interspecific phylogenetic relationship affect S allele polymorphism. In searching for patterns of lineage sorting among species of various phylogenetic relationships, 22 S-alleles from 34 genets randomly taken at three Tennessee sites from a newly known GSI species Physalis longifolia were sequenced. Analyses of these data along with the previous sequences of three solanaceous species indicate that much of the combined allelic genealogy may be explained by lineage sorting and phylogenetic relationship. Using the mean terminal branch lengths of trans-specific alleles on the allelic genealogy to infer phylogenetic relationship among species, P. longifolia was found to be more closely related to P. cinerascens than to P. crassifolia. Nonetheless, the distribution of terminal branch lengths of P. longifolia was more similar to that of P. crassifolia than to that of P. cinerascens, suggesting phylogenetic relationship may have little effect on species-specific polymorphism. Similar habitat and growth characters, yet contrasting S-polymorphism, between P. longifolia and P. cinerascens also reject previous hypotheses that habitat and growth characters are the major factors responsible for interspecific differences in S-polymorphism. A likely scenario is that species-specific S-polymorphism is based on lineage sorting whose effect is further modified by species age and historical changes in population parameters. PMID:11380665

PubMed

To check the nutritional and mineral contents of four medicinal plants viz., Peganum hermla, Solanum nigrum, Mentha longifolia, Achryanthus aspera, which are used as medicine traditionally in Soon Valley Khushab, Pakistan. Proximate analysis of plant sample determined that protein (7.491%) and ash (22.79%) was highest in Mentha longifolia, carbohydrate (75.23%) in Peganum hermla, fats (12.595%) and moisture (6.82%) was highest in Achryanthus aspera. In comparative assessment of the various species, the results showed that Achryanthus aspera. is the most significant species having higher concentrations of fat, fibre values compared to the other species. Absorption Spectrometric method was used for the elemental analysis of essential elements such as Fe, Cd, Cu,Mn, Pb, Cr, Ni and Na in medicinal plants in different range. PMID:24811823

Withanolide artifacts formed in methanol.  

PubMed

Methanol solutions of the main withanolides (6-8) naturally present in Physalis longifolia yielded five artificial withanolides (1-5), including three new compounds (1-3). Withanolides 1 and 2 were identified as intramolecular Michael addition derivatives, while withanolides 3-5 were the result of intermolecular Michael addition. A comprehensive literature investigation was conducted to identify potential withanolide Michael addition artifacts isolated from Solanaceous species to date. PMID:24152046

Pre-meiotic bands and novel meiotic spindle ontogeny in quadrilobed sporocytes of leafy liverworts (Jungermannidae, Bryophyta)  

Microsoft Academic Search

Indirect immunofluorescence and confocal microscopy were used to study the nucleation and organization of microtubules during\\u000a meiosis in two species of leafy liverworts, Cephalozia macrostachya and Telaranea longifolia. This is the first such study of sporogenesis in the largest group of liverworts important as living representatives of some\\u000a of the first land plant lineages. These studies show that cytoplasmic quadrilobing
