Abstract (sommario):

The chemical exploration of extracts from cultures of the marine bacterial isolate PNG-276 yielded the novel antibiotic tauramamide (2.13), a non-ribosomal peptide active against cultures of Enterococcus sp. and methicillin-resistant Staphylococcus aureus (MRSA). A study of extracts of the marine sponge Spirastrella coccinea yielded the novel macrolide methylspirastrellolide C (3.14), which is active against protein phosphatase 2A (PP2A). A third study examined sponge extracts active in a cannabinoid receptor assay, yielding two known compounds, an A- nor -steroid derivative (4.10) and bengamide A (4.11). Neither purified compound was active in the cannabinoid receptor assay, although in both cases this is the first report of these compounds being isolated from Stylissa massa and Hemiasterella aff. affinis sponges, respectively.

Abstract (sommario):

The focus of this thesis was to study the chemotaxonomic relationship of selected southern Australian marine brown algae of the genera Cystophora and Sargassum. Consequently, this resulted in the isolation and structure elucidation of six new terpenoids from two southern Australian marine brown algae Cystophora moniliformis and Sargassum fallax together with 10 previously reported natural products. As a result of the re-isolation of these known secondary metabolites, updated and complete structural characterisation data could be provided for the first time for 7 of these compounds. Chemotaxonomic studies of Cystophora moniliformis resulted in the isolation of two new cyclic epimeric terpene diols moniliforminol A (3.25) and moniliforminol B (3.26), a new linear farnesyl acetone derivative (3.27) and the previously described terpenoids (3.19)-(3.24). This study also resulted in the first complete 2D NMR characterisation for compounds (3.21) to (3.24) as well as the first report of (3.24) occurring as a natural product. All structures were elucidated by detailed spectroscopic analysis with the relative configurations of (3.25) and (3.26) being established by selective 1D nOe NMR experiments. The proposed biosynthetic pathway for the above compounds has also been described. Chemical investigation of the Southern Australian marine brown alga Sargassum fallax resulted in the isolation of three new meroditerpenoids fallahydroquinone (4.8), fallaquinone (4.9) and fallachromenoic acid (4.10), together with the previously reported compounds sargaquinone (4.1) (isolated and identified in a mixture with sargaquinoic acid), sargahydroquinoic acid (4.2), sargaquinoic acid (4.3) and sargachromenol (4.11). As a result of this study the complete 2D NMR characterisation for sargahydroquinoic acid (4.2) and sargaquinoic acid (4.3) could also be reported for the first time. All structures were elucidated by detailed spectroscopic analysis. Sargahydroquinoic acid (4.2) and sargaquinoic acid (4.3) displayed moderate antitumour activity.

Abstract (sommario):

Two new β-carboline alkaloids were isolated from the bryozoan Cribricellina cribraria. One of these, 1-vinyl-8-hydroxy-β-carboline, was the major cytotoxic component of the extract, while the other had a novel sulphone structure. Several other known β-carboline alkaloids were also isolated from the extract. To investigate structure-activity relationships in these compounds, several derivatives of the major alkaloid were prepared and a number of 1-substituted β-carboline alkaloids synthesised. Nmr spectroscopic studies of these compounds were carried out and previously published ¹³C nmr data for some of these compounds revised. Homarine was isolated as the major water soluble component of the extract and the sterol composition examined. Known β-carboline alkaloids were isolated from the related bryozoan Margaretta barbata. The known biologically active compounds, girolline and hymenialdisine were isolated from the sponge Axinella sp. 2. As some discrepancies between the experimental and published data on hymenialdisine were noted, an X-ray crystal structure analysis was performed. Oroidin, homarine and taurine were also isolated from the extract and the sterol composition found to consist exclusively of ring-contracted A norstanols. An extract of the sponge Stylopus australis was found to contain a new sterol sulphate and two derivatives of this compound were prepared. The full assignment of the ¹H nmr spectrum of the sulphate was achieved with the aid of COSY, nOe, HETCOR and XCORFE nmr experiments. The glyceryl ether, chimyl alcohol was also isolated from the sponge. An extract of the related sponge, Hymedesmia sp. 1 was examined and rhodoic acid isolated as the major water soluble component, along with homarine. The sterol compositions of Stylopus australis and Hymedesmia species 1 and 2 were examined for comparative purposes. Studies on an extract of the sponge Hymeniacidon hauraki led to the isolation of a new furan fatty acid. The sterol corbisterol and its peroxide were isolated from one sample of the sponge and this led to an examination of infraspecific sterol variation in this species. A screening procedure of biologically active natural product extracts has been developed. The procedure involves examining the chromatographic behaviour of the biological activity of an extract and is designed to detect known biologically active compounds and to determine the best means of handling extracts containing unknown biologically active components.

Abstract (sommario):

An investigation of the marine sponge Halisarca sp. was carried out following the discovery of strong activities in antiviral and P388 murine leukaemia assays of an extract from this sponge. A polyether type of compound is suspected as the cause of this activity. The investigation of Halisarca sp. made a significant contribution to the development of a chemical screening process. The absolute configuration of pateamine has been elucidated by a combination of degradative and synthetic chemistry utilising formation of diastereoisomers with Mosher's acid. Several other derivatives of pateamine are reported. The algal metabolite thyrsiferol has been isolated from the digestive gland of the marine mollusc Aplysia parvula. The egg masses of A. parvula have also been examined. The NMR characterisation of the thyrsiferol has been extended through the extensive use of one- and two- dimensional spectroscopic experiments.

Abstract (sommario):

The halichondrins are a series of polyether macrolides displaying potent in vitro and in vivo antitumour activities and, as such, represent important leads as anticancer drugs. These compounds had previously been isolated from a number of unrelated marine sponges, such as Lissodendoryx sp., a high yielding deep-water sponge located off the Kaikoura coast of New Zealand. Structure-activity relationships in the halichondrin senes have now been investigated. Hemi-synthetic modifications of selected naturally-occurring halichondrins have produced over fourteen new analogues. The biological activities of twelve of these analogues have been assessed in an in-house P388 in vitro assay and in the National Cancer Institute's (USA) in vitro sixty cell-line human tumour panel. An analysis of these data has shown that the lactone ring (C1-C30), the olefinic functionalities (C19 and C26), the natural C38 stereochemistry and the tricyclo ring system (C-E rings) are essential structural features of the halichondrins. The characterisation of the hemi-synthetic derivatives has been facilitated by the full NMR spectroscopic assignments of halichondrin B and homohalichondrin B. The future progress of the halichondrins as anticancer drugs will have been assisted by the development of an understanding of the general chemistry of the halichondrins.

Abstract (sommario):

The bioactivity directed analysis of the extract from a sponge of the genus Sarcotragus led to the isolation of a series of bioactive sesterterpenes, of which variabilin (1a) was the major component. The sesterterpenes (29a), (30) and (31a), along with the related C₂₁ furanoterpene (32), were present in lesser amounts. The unequivocal assignment of the stereochemistry of the 20,21 double bond in variabilin as 20(Z) was achieved through examination of the22-O-methyl derivative (1b) of variabilin and the isolation of the variabilin isomer (29a) with the 20(E) stereochemistry. Variabilin was also isolated from a sponge of the genus lrcinia. The four related bioactive sesterterpenes (33b), (34b), (35b), and (36b) together with (31b) were isolated from a methylated extract from the same sponge. Variabilin autooxidised in the presence of light and air to form a mixture of products that underwent further oxidation on standing. The 22-O-methyl derivative (1b) of variabilin did not autooxidize but underwent oxidation in the presence of the singlet oxygen sensitizer, rose bengal. The products from this oxidation reaction were (48b), (49b), (50b), (51b), (52b), (53b), (50b), (61b), (62b), (63b), (64b) and (65b) and these were the same as the products from the variabilin autooxidation with the exception of the methyl group at C₂₂. Variabilin autooxidation was shown to occur through the production of singlet oxygen and subsequent oxygen addition to the furan moiety. The production of singlet oxygen occurred through a sensitization mechanism involving the variabilin tetronic acid moiety. To investigate structure-bioactivity relationships in variabilin and related sesterterpenes, derivatization of the furan and tetronic acid moieties in variabilin was carried out. 22-O-Me variabilin (1b), in contrast to variabilin, reacted favourably under most furan reaction conditions and so a number of reactions were carried out on (1b) also. Hydrogenation of variabilin gave the cytotoxic compound (73). Dials-Alder addition of DMAD to variabilin gave the cytotoxic compounds (74a) and (75a) and acylation gave the cytotoxic compounds (81) and (82). Reduction of these acylation products gave the cytotoxic derivatives (83) and (84). The non-cytotoxic compound (85) was formed on reaction of p-bromobenzoylchloride with variabilin. Dials-Alder addition of DMAD to 22-O-Me variabilin gave the cytotoxic compounds (74b) and (75b) and addition of 4-phenyl-1,2,4-triazoline-3,5-dione (phenyl-TD) (78) gave the potential antiviral compounds (76) and (77). A cytotoxic sesquiterpene (86) with a tricyclo[6.3.1.0.²,⁵]dodecane skeleton has been isolated from the extract of a New Zealand Eurypon sp. of sponge. Two derivatives, (87) and (88), of this sesquiterpene have also been isolated, probably as artefacts arising during the isolation procedure. The structure of a spirosesquiterpene (89), also obtained from the sponge extract, has been determined. Previously published nmr assignments for β-caryophyllene alcohol (90) have been revised. Three further compounds, labeled unknowns a-c, were isolated, but their structures were not determined. One of these unknowns (unknown a) was probably a sesquiterpene, and was shown to be cytotoxic, while the remaining two (unknowns band c) gave spectroscopic data which indicated that while they were very closely related to one another, they were not sesquiterpenes. Bioassay directed isolations of the active components from a new sponge, genus Chondropsis, and the bryozoan, Margaretta barbata, were attempted. The bryozoan, Margaretta barbata had previously been shown to exhibit significant in vivo P388 activity. For the Chondropsis species the components responsible for the observed biological activity appeared to be very minor components of the overall sponge and isolation of the active compounds was not achieved. For the bryozoan the more polar active material was present in reasonable abundance and a compound (unknown d) giving in vitro P388 activity was isolated. However full characterisation of this compound was not achieved. The compound, or compounds, responsible for the biological activity shown by the less polar material were not isolated. Sterols were shown to be major components of the non-polar organic material in both the sponge and bryozoan species studied. For the Chondropsis sponge the major sterol component was identified as 24-methylene-cholesterol (92). For the bryozoan, Margaretta barbata, the major sterol was identified as cholesterol (93) with 24-methylene-cholesterol (92) and cholest-4-en-3-one (94) also being identified. The major organic water soluble compound was identified as homarine (95).

Abstract (sommario):

CV-N is an 11 kDa, anti-HIV protein that binds strongly to the envelope glycoprotein, gp120, expressed on the outer surface of the free virion and also on HIV-infected cells. As such, it represents an important lead for development of anti-HIV therapeutics. Marine toxins such as the halichondrins have potent in vivo cytotoxicities and are lethal to cells. The combination of this potency of the marine toxins with the unique targeting capability of CV-N has been harnessed to produce conjugates that have the potential to selectively target and eliminate HIV-infected cells. Three forms of the protein were developed; the native protein itself, a derivative recombinantly produced in E. coli with an extra cysteine at the C-terminal (CV-N-Cys) and CV-N with the lysine side chain amines converted into thiols (thiolated-CV-N). To facilitate release of the toxin within infected cells an enzymatically-cleavable pHdependent biolinker was incorporated separating the toxin from the protein. The chemistry required for incorporation of protein, biolinker, and toxin, was established through synthesis of fluorescently labelled conjugates capable of reaction with CV-N. Biological testing of these derivatives showed no interference with the anti-HIV activity of the CV-N when conjugated in these model compounds. Synthetic strategies were developed to produce two derivatives of norhomohalichondrin B amine, both containing the cleavable biolinker, but with activation from succinimidyl esters and maleimido groups respectively. Native CV-N was reacted with the succinimidyl ester derived toxin construct to produce a CV-N-biolinker-toxin conjugate. The maleimido derivative toxin construct was reacted with both CV-N-Cys and thiolated-CV -N to produce closely related CV-N-toxin conjugates. Investigations into the binding properties and cell toxicities of these conjugates is currently underway.

Abstract (sommario):

The transdisciplinary National Academies Keck Futures Initiative (NAKFI) conference on the Deep Blue Sea sparked a collaboration between sonification expert Mark Ballora and marine biologist and sound artist Heather Spence. Research involving long-term Marine Passive Acoustic Monitoring (MPAM) of the MesoAmerican Reef system forms the basis for a gradient of audio products: 1) layering a tour guide acoustic instrument over raw and manipulated soundscape recordings; 2) layering of multiple acoustic instruments over duty cycle interpretation sampling; and 3) layering of data sonification over the original data, with additional acoustic instrument layers. The audio products are designed to promote data exploration and understanding by researchers and students, as well as an emotional impact musically with conservation themes. Presentations have included live and virtual performances and workshops. Next steps include sonification of other correlated environmental data with the original sound data in raw, manipulated, and sonified forms.

Abstract (sommario):

In the context of global warming, the built environment offers relevant opportunities to reduce GHG emissions that underlie climate change. In particular, this can be achieved with the development of low-embodied energy building materials such as bio-based concretes. Hemp concrete has been the subject of many investigations in the field of non-load bearing infill walls in France since the early 1990s. In addition to hygrothermal performances, the use of crop by-products definitely helps to limit the carbon footprint. Hemp concretes are often produced by mixing the plant aggregates with lime-based binders. The latter have many benefits among which the water vapor permeability. However, CO2 emissions due to the decarbonation of limestone for the production of lime largely contribute to the overall environmental balance of these materials. The use of natural pozzolans (volcanic scoria) combined with hydrated lime goes back to the Greco-Roman period and reduces carbon emissions. Nonetheless, it does not necessarily meet the issue related to the depletion of granular natural resources. Hence, this study deals with the design of a new low-carbon binder based on marine dredged sediment seen as an alternative strategic granular resource that can be considered renewable. The sediment comes from the Port of Dunkirk in the North of France and is mainly composed of silt and quartz sand. It was finely ground and compared to a lowly reactive basaltic pozzolan. Lime-pozzolan pastes were prepared and stored in a moist environment under room (20°C) and high temperature (50°C). The hardening kinetics of pastes was followed through mineralogical studies (TGA, XRD) and compressive strength development. The results showed that the hardening of pastes including the marine sediment was suitable in the case of samples stored at 50°C and make it possible to use such a binder for precast bio-based concretes.

Abstract (sommario):

During research cruise AL595 (31.5. - 20.6.2023) onboard research vessel ALKOR, investigations were carried out at the Grimsey Hydrothermal Field offshore Northern Iceland as part of the Helmholtz InnoPool project “High CO2 – metabolic responses and bioeconomic opportunities”. For the first time, the Hover-AUVs Anton and Luise were successfully operated at water depths of up to 400m, which is close to the maximum operational depth of 500m specified for these Girona 500 AUVs. AUV Anton was used to measure high resolution multibeam data with a horizontal resolution of approximately 40cm cov- ering a total area of ca. 1.4km2. AUV Luise acquired five photo-mosaics with sub-centimeter resolution covering a total area of ca. 5.000m2. In addition, both AUVs carried CTD probes, which will allow to investigate the local distribution of hydrothermal activity. Both high-resolution bathymetry and pho- togrammetry data yield new insights into the morphology and overall structure of the vent site and its surrounding, which will be valuable for the interpretation of geophysical data previously acquired in the working area. Sampling with a multicorer (three successful deployments), a 300cm long gravity corer (five successful deployments), a BIGO lander (two successful deployments) and casts with the CTD- rosette (seven deployments) generated fluid, pore-fluid and sediment samples to be analyzed by the working groups Geomicrobiology and Biogeochemistry, Marine Natural Products and Marine Geochem- istry at GEOMAR and at Matís (Iceland, Natural Products only). Lab work to be carried out in the home labs will yield insights into the physiological adaptation of microbial communities and individual microbes to very high CO2 concentrations and will explore microbial utilization of CO2 for establishing CO2-based bioeconomic value chains.

Abstract (sommario):

This report details the cumulative shoreline miles and water acres within the 88 ocean, coastal, and Great Lakes National Park units. Across the National Park Service (NPS), there is a total of 14,350 shoreline miles and 2,534,595 water acres. This report serves as an update to the NPS Natural Resource Report titled, ?Shoreline length and water area in the ocean, coastal and Great Lakes Parks: Updated statistics for shoreline miles and water acres (rev 1b)? (Curdts 2011). Note: For park units located in ocean settings, ?water acres? refers to marine, estuarine, and tidally influenced waters. For park units in the Great Lakes region, ?water acres? refers to freshwater. For all park units, freshwater bodies such as lakes, ponds, and rivers that exist inland of the marine or Great Lake shoreline are excluded from the calculation. Existing shoreline products from federal, state, and NPS sources were visually assessed for each park and compared to reference imagery within ESRI ArcGIS Pro to determine the best available data. The resulting shoreline delineation for each park was reviewed by NPS park, regional, national, and/or Inventory and Monitoring Network staff, and manual adjustments were made as needed to accurately reflect the shoreline. Park boundaries were defined according to the NPS Land Resources Division (LRD), with a few exceptions as noted within the report. Shoreline miles and water acres within each park?s boundary were then calculated within a GIS framework. The results of this report represent a snapshot in time, and variation is to be expected given the dynamic nature of coastal environments. Future updates to these statistics may be calculated as new data become available. These shoreline miles and water acres statistics and associated geospatial data and maps are intended for general reference only; they are useful for describing the scale of NPS holdings and management responsibilities.

Abstract (sommario):

This Coastal and Hydraulics Engineering Technical Note (CHETN) presents the evaluation of a rapidly deployable radar and associated software for characterizing surf-zone waves, currents, and bathymetries at the US Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory (CHL), Field Research Facility (FRF), in Duck, North Carolina. This project was conducted at the request of the US Marine Corps (USMC) Warfighting Laboratory. The Version 1 Advanced Tactical Awareness Kit–Radar Expeditionary (ATAK-ER V1) system was deployed 15 times between July and August 2023 to observe a range of wave, water level, and wind conditions that could each affect radar processing. Products from the system were then compared to the FRF’s continuously operating in situ instruments and monthly bathymetric surveys to quantify the accuracy and reliability of the output. A number of issues with the unit are identified, including potential error sources contributing to inaccuracies, but the black-box nature of the commercial off-the-shelf (COTS) unit prevents a confident understanding of why wave heights are underpredicted (by 65% on average), why bathymetries consistently have root-mean-square errors (RMSE) over 1 m with progressively greater errors with distance offshore, or why some collections are unable to generate all of the advertised products. This Version 1 COTS unit is not recommended for operational use at this time.

Testo completo

Abstract (sommario):

The overall objective of this proposal is to understand how realistic strategies for incorporating alternative foods into wheat fields affect the intraguild (IG) interactions of omnivorous and carnivorous predators and their efficacy as biological control agents. Cereal aphids are a primary pest of wheat throughout much of the world. Naturally occurring predator communities consume large quantities of cereal aphids in wheat, and are partitioned into aphid specialists and omnivores. Within wheat fields, the relative abilities of omnivorous and carnivorous predators to reduce cereal aphids depend heavily on the availability, distribution and type of alternative foods (alternative prey, sugar, and pollen), and on the intensity and direction of IG predation events within this community. A series of eight synergistic experiments, carefully crafted to accomplish objectives while accounting for regional production practices, will be conducted to explore how cover crops (US, where large fields preclude effective use of field margins) and field margins (IS, where cover crops are not feasible) as sources of alternative foods affect the IG interactions of predators and their efficacy as biological control agents. These objectives are: 1. Determine the mechanisms whereby the availability of alternative prey and plant-provided resources affect pest suppression by omnivorous and carnivorous generalist predators; 2. Characterize the intensity of IGP within generalist predator communities of wheat systems and assess the impact of these interactions on cereal aphid predation; and 3. Evaluate how spatial patterns in the availability of non-prey resources and IGP affect predation on cereal aphids by generalist predator communities. To accomplish these goals, novel tools, including molecular and biochemical gut content analysis and geospatial analysis, will be coupled with traditional techniques used to monitor and manipulate insect populations and predator efficacy. Our approach will manipulate key alternative foods and IG prey to determine how these individual interactions contribute to the ability of predators to suppress cereal aphids within systems where cover crop and field margin management strategies are evaluated in production scale plots. Using these strategies, the proposed project will not only provide cost-effective and realistic solutions for pest management issues faced by IS and US producers, but also will provide a better understanding of how spatial dispersion, IG predation, and the availability of alternative foods contribute to biological control by omnivores and carnivores within agroecosystems. By reducing the reliance of wheat producers on insecticides, this proposal will address the BARD priorities of increasing the efficiency of agricultural production and protecting plants against biotic sources of stress in an environmentally friendly and sustainable manner.

Abstract (sommario):

This study assesses the interaction between climate change and agricultural trade policies. We distinguish between two dimensions of agricultural trade policy: market insulation and subsidy levels. Building on the previous work of Tsigas, Frisvold and Kuhn (1997) we find that, in the presence of current levels of agricultural subsidies, increased price transmission --as called for under the Uruguay Round Agreement on Agriculture-- reduces global welfare in the wake of climate change. This is due to the positive correlation between productivity changes and current levels of agricultural support. Increases in subsidized output under climate change tend to exacerbate inefficiencies in the global agricultural economy in the absence of market insulation. However, once agricultural subsidies have also been eliminated, price transmission via the global trading system contributes positively to economic adaptation under climate change. products. This may partially explain the relatively slow growth of world grain import demand in recent years. In addition, bilateral agreements with East Asia, NAFTA, and the evolution of the CAP, have all had important impacts on the structure of world food and agricultural trade. The objective of this paper is to assess the relative role of each of the major forces-- consumer demand, factor accumulation, transport costs, and policy change--in driving changes in the composition of world food trade in 1980-1995. To do so, we employ a modified version of the Global Trade Analysis Project (GTAP) model of world trade which permits us to isolate the contribution of each of these related factors to the changing composition of world food trade in a general equilibrium context. We evaluate the relative role of each of these factors by simulating the model backwards in time, from 1995 to 1980 under different assumptions. This general approach, termed “backcasting” (i.e. backwards forecasting), takes as exogenous the basic drivers of change and attempts to explain the resulting change in food trade composition. The model-produced changes in the composition of agricultural and food trade are compared with historical trade data, to determine the relative importance of each factor on the changing composition of food trade. Given limited space, our focus will be on explaining the changes in the global composition of food and agriculture trade. A natural follow-on effort would target specific markets in more detail. This type of backcasting approach was first employed by Gehlhar (1997) who sought to explain the shift in exports of primary commodities to manufactures in East Asia in the 1980's. He calibrated the GTAP model to 1992 data, then implemented shocks to factor endowments and economywide total factor productivity (TFP) in order to force each economy back to its 1982 levels of population, land, labor, human capital, physical capital and technology. By comparing actual and predicted changes in export shares in this period, he found human capital accumulation played a key role in explaining the change in the aggregate composition of East Asian exports. Gehlhar, Hertel and Martin (1994) built on this work in an effort to predict future changes in the pattern of agricultural trade from 1992-2002. They also emphasized the importance of supply-side determinants of agricultural trade. In this paper, we go beyond this earlier work in a number of ways. First, we focus on the composition of agricultural exports, rather than simply looking at the share of agriculture in total trade. Secondly, we incorporate the Cranfield et al. estimates of Rimmer and Powell’s recently developed, implicitly directly additive demand system (nicknamed AIDADS) into the GTAP model. This permits us to better capture the impact of demand-side changes on the pattern of global tr

Abstract (sommario):

Botrytis cinerea is the postharvest pathogen of many agricultural produce with table grapes, strawberries and tomatoes as major targets. The high efficiency with which B. cinerea causes disease on these produce during storage is attributed in part due to its exceptional ability to develop at very low temperature. Our major goal was to understand the genetic determinants which enable it to develop at low temperature. The specific research objectives were: 1. Identify expression pattern of genes in a coldenriched cDNA library. 2. Identify B. cinerea orthologs of cold-induced genes 3. Profile protein expression and secretion at low temperature on strawberry and grape supplemented media. 4. Test novel methods for the functional analysis of coldresponsive genes. Objective 1 was modified during the research because a microarray platform became available and it allowed us to probe the whole set of candidate genes according to the sequence of 2 strains of the fungus, BO5.10 and T4. The results of this experiment allowed us to validate some of our earlier observations which referred to genes which were the product of a SSH suppression-subtraction library. Before the microarray became available during 2008 we also analyzed the expression of 15 orthologs of cold-induced genes and some of these results were also validated by the microarray experiment. One of our goals was also to perform functional analysis of cold-induced genes. This goal was hampered for 3 years because current methodology for transformation with ‘protoplasts’ failed to deliver knockouts of bacteriordopsin-like (bR) gene which was our primary target for functional analysis. Consequently, we developed 2 alternative transformation platforms, one which involves an air-gun based technique and another which involves DNA injection into sclerotia. Both techniques show great promise and have been validated using different constructs. This contribution is likely to serve the scientific community in the near future. Using these technologies we generated gene knockout constructs of 2 genes and have tested there effect on survival of the fungus at low temperature. With reference to the bR genes our results show that it has a significant effect on mycelial growth of the B. cinerea and the mutants have retarded development at extreme conditions of ionic stress, osmotic stress and low temperature. Another gene of unknown function, HP1 is still under analysis. An ortholog of the yeast cold-induced gene, CCH1 which encodes a calcium tunnel and was shown to be cold-induced in B. cinerea was recently cloned and used to complement yeast mutants and rescue them from cold-sensitivity. One of the significant findings of the microarray study involves a T2 ribonuclease which was validated to be cold-induced by qPCR analysis. This and other genes will serve for future studies. In the frame of the study we also screened a population of 631 natural B. cinerea isolates for development at low temperature and have identified several strains with much higher and lower capacity to develop at low temperature. These strains are likely to be used in the future as candidates for further functional analysis. The major conclusions from the above research point to specific targets of cold-induced genes which are likely to play a role in cold tolerance. One of the most significant observations from the microarray study is that low temperature does not induce ‘general stress response in B. cinerea, which is in agreement to its exceptional capacity to develop at low temperature. Due to the tragic murder of the Co-PI Maria R. Davis and GopiPodila on Feb. 2010 it is impossible to deliver their contribution to the research. The information of the PI is that they failed to deliver objective 4 and none of the information which relates to objective 3 has been delivered to the PI before the murder or in a visit to U. Alabama during June, 2010. Therefore, this report is based solely on the IS data.

Abstract (sommario):

The UK has a legal commitment to reach net zero carbon (NZC) emissions by 2050. This is a topic that has recently been building momentum, with clean growth being one of the four Grand Challenges set out by the UK Government. The ways we grow, process and transport food are major contributors to climate change, accounting for more than a quarter of all greenhouse gas emissions. Reducing this will require substantial changes in agriculture, manufacturing, and transport. Consequently, the Science Council and FSA Chief Scientific Adviser (CSA) agreed that a deeper understanding of the potential implications of achieving net zero on food systems, together with identification of areas of uncertainty, would be of considerable value to FSA in pre-empting future policy and evidence needs in this area. In early discussions to scope the work required, Defra indicated to the FSA Science Council Secretariat that there are many new developments and changes to activity in primary production aimed at achieving net zero. The Science Council agreed, therefore, to concentrate its first investigations on changes expected in primary food production. Primary production is the production of chemical energy in organic forms by living organisms. The main source of this energy is sunlight. For the purposes of this review, primary food production includes the growing and harvesting of plants as food for humans or feed for animals, and the rearing and slaughter of animals including livestock, fish and a wide variety of aquatic and marine organisms. A Science Council Working Group 6 (WG6) began work in summer 2021, led by Science Council members Mrs Claire Nicholson (WG6 Chair) and Prof Jonathan Wastling (WG6 Deputy Chair). The brief for WG6 is to investigate the potential food safety implications arising from changes to primary food production practices and technologies that reduce carbon emissions in the next 10 years. The work programme (described in this report) covers 4 phases, with phases 1 and 2 now complete. The work so far has drawn diverse, wide-ranging, sometimes slightly conflicting, views and opinions from across academia, the FSA, Defra, industry bodies and individual food producers. This interim report summarises: The work undertaken to date (phases 1 and 2) What has been learnt including changes to practice already underway or imminent Issues arising from the changes that the FSA should be aware of Further work planned by WG6 to understand the nature of the risks in more depth (phases 3 and 4) The Science Council aims to complete its investigations by the end of 2022 and present its findings to the FSA Board as soon as possible afterwards.

Testo completo

Abstract (sommario):

Fire models are presently employed by fire investigators to make predictions of fire dynamics within structures. Predictions include the evolution of gas temperatures and velocities, smoke movement, fire growth and spread, and thermal exposures to surrounding objects, such as walls. Heat flux varies spatially over exposed walls based on the complex thermal interactions within the fire environment, and is the driving factor for thermally induced fire damage. A fire model predicts the temperature and heat transfer through walls based on field predictions, such as radiative and convective heat flux, and is also subject to the boundary condition represen-tation, which is at the discretion of model practitioners. At the time of writing, Fire Dynamics Simulator can represent in-depth heat transfer through walls, and transverse heat transfer is in a preliminary development stage. Critically, limited suitable data exists for validation of heat trans-fer through walls exposed to fires. Mass loss and discoloration fire effects are directly related to the heat transfer and thermal decomposition of walls, therefore it is crucial that the representation of transverse heat transfer in walls in fire models be validated to ensure that fire investigators can produce accurate simulations and reconstructions with these tools. The purpose of this study was to conduct a series of experiments to obtain data that addresses three validation spaces: 1) thermal exposure to walls from fires; 2) heat transfer within walls exposed to fires; and 3) fire damage patterns arising on walls exposed to fires. Fire Safety Research Institute, part of UL Research Institutes, in collaboration with the Bureau of Alcohol, Tobacco, Firearms and Explosives Fire Research Laboratory, led this novel research endeavor. Experiments were performed on three types of walls to address the needs in this validation space: 1. Steel sheet (304 stainless steel, 0.793 mm thick, coated in high-emissivity high-temperature paint on both sides). This wall type was used to support the heat flux validation objective. By combining measurements of gas temperatures near the wall with surface temperatures obtained using infrared thermography, estimates of the incident heat flux to the wall were produced. 2. Calcium silicate board (BNZ Marinite I, 12.7 mm thick). This wall type was used to support the heat transfer validation objective. Since calcium silicate board is a noncombustible material with well-characterized thermophysical properties at elevated temperatures, measurements of surface temperature may be used to validate transverse heat transfer in a fire model without the need to account for a decomposition mechanism. 3. Gypsum wallboard (USG Sheetrock Ultralight, 12.7 mm thick, coated in white latex paint on the exposed side). This wall type was used to support the fire damage patterns validation objective. Two types of fire effects were considered: 1) discoloration and charring of the painted paper facing of the gypsum wallboard; and 2) mass loss of the gypsum wallboard (which is related to the calcination of the core material). In addition to temperature and heat flux measurements, high resolution photographs of fire patterns were recorded, and mass loss over the entirety of the wall was measured by cutting the wall into smaller samples and measuring the mass of each individual sample. A total of 63 experiments were conducted, encompassing seven fire sources and three wall types (each combination conducted in triplicate). Fire sources included a natural gas burner, gasoline and heptane pools, wood cribs, and upholstered furniture. A methodology was developed for obtaining estimates of field heat flux to a wall using a large plate heat flux sensor. This included a numerical optimization scheme to account for convection heat transfer. These data characterized the incident heat flux received by calcium silicate board and gypsum wallboard in subsequent experiments. Fire damage patterns on the gypsum wallboard, attributed to discoloration and mass loss fire effects, were measured. It was found that heat flux and mass loss fields were similar for a given fire type, but the relationship between these measurements was not consistent across all fire types. Therefore, it was concluded that cumulative heat flux does not adequately describe the mass loss fire effect. Fire damage patterns attributed to the discoloration fire effect were defined as the line of demarcation separating charred and uncharred regions of the wall. It was found that the average values of cumulative heat flux and mass loss ratio coinciding with the fire damage patterns were 10.41 ± 1.51 MJ m−2 and 14.86 ± 2.08 %, respectively. These damage metrics may have utility in predicting char delineation damage patterns in gypsum wallboard using a fire model, with the mass loss ratio metric being overall the best fit over all exposures considered. The dataset produced in this study has been published to a public repository, and may be accessed from the following URL: <https://doi.org/10.5281/zenodo.10543089>.
