A class of plants within the Bryophyta comprising the mosses, which are found in both damp (including freshwater) and drier situations. Mosses possess erect or prostrate leafless stems, which give rise to leafless stalks bearing capsules. Spores formed in the capsules are released and grow to produce new plants. (Concise Dictionary of Biology, 1990). Many small plants bearing the name moss are in fact not mosses. The "moss" found on the north side of trees is actually a green alga (CHLOROPHYTA). Irish moss is really a red alga (RHODOPHYTA). Beard lichen (beard moss), Iceland moss, oak moss, and reindeer moss are actually LICHENS. Spanish moss is a common name for both LICHENS and an air plant (TILLANDSIA usneoides) of the pineapple family. Club moss is an evergreen herb of the family LYCOPODIACEAE.
A class of minute animals of the phylum Aschelminthes.

Effect of desiccation on the ultrastructural appearances of Acinetobacter baumannii and Acinetobacter lwoffii. (1/770)

An Acinetobacter baumannii isolate survived desiccation beyond 30 days and an Acinetobacter lwoffii isolate up to 21 days. For both species, desiccation resulted in a significant increase in the proportion of round cells (A baumannii, 40% to 80%; A lwoffii, 51% to 63%) and a significant decrease in rod shaped cells (A baumannii, 58% to 13%; A lwoffii, 46% to 34%). Electronmicroscopic examination showed that there was also a corresponding significant increase in the cell wall thickness (A baumannii, up to 53%; A lwoffii, up to 26%). Desiccated A baumannii cells became more electron-dense and had significantly thicker cell walls (x1.3) than those of A lwoffii. Cell wall structures of A baumannii strains with different abilities to resist desiccation deserve further study.  (+info)

Evaluation of dehydrated restaurant food waste products as feedstuffs for finishing pigs. (2/770)

Two dehydrated restaurant food waste (DFW) products were evaluated as potential feedstuffs for finishing pigs. For each product, fresh food wastes were obtained from food service operations at a resort complex in central Florida. The wastes were mostly leftover food and plate scrapings. The wastes were minced, blended with a feed stock (soy hulls and wheat flour [DFW1] or soy hulls and ground corn [DFW2]), pelleted, and dried. The dried product was then blended with additional minced fresh food wastes and dried; this process was then repeated. The final DFW products contained approximately 60% dried food wastes. The DFW1 and DFW2 products contained 11.4 and 8.4% moisture, 15.0 and 14.4% CP, 13.8 and 16.0% crude fat, 10.4 and 14.5% crude fiber, 5.8 and 4.7% ash, .63 and .64% lysine, .54 and .63% Ca, .34 and .38% P, .69 and .86% Cl, and .35 and .47% Na, respectively. Two feeding trials with 48 and 72 finishing pigs (56 to 112 kg), respectively, were conducted comparing diets without (control) or with the DFW product included at 40% of the diet (DFW1) for Trial 1 and 40 or 80% of the diet (DFW2) for Trial 2. Pigs fed the DFW diets in both trials had ADG that were similar (P > . 10) to and average gain:feed ratios that were superior (P = .06, Trial 1; P < .01; linear, Trial 2) to those for control pigs. Carcass lean content and lean quality scores were not reduced (P > . 10) by feeding pigs the DFW diets in either trial. Carcass fat became softer (P < .01; linear) with increasing amount of DFW2 in the diet in Trial 2. Thus, dehydrated restaurant food wastes have the potential to produce a nutritious feedstuff for pigs while offering a viable solid waste disposal option.  (+info)

Dehydration and crystallization of trehalose and sucrose glasses containing carbonmonoxy-myoglobin. (3/770)

We report a study wherein we contemporarily measured 1) the dehydration process of trehalose or sucrose glasses embedding carbonmonoxy-myoglobin (MbCO) and 2) the evolution of the A substates in saccharide-coated MbCO. Our results indicate that microcrystallization processes, sizeably different in the two saccharides, take place during dehydration; moreover, the microcrystalline structure is maintained unless the dry samples are equilibrated with a humidity >/=75% (>/=60%) at 25 degrees C for the trehalose (sucrose) sample. The evolution of the parameters that characterize the A substates of MbCO indicates that 1) the effects of water withdrawal are analogous in samples dried in the presence or in the absence of sugars, although much larger effects are observed in the samples without sugar; 2) the distribution of A substates is determined by the overall matrix structure and not only by the sample water content; and 3) the population of A0 substate (i. e., the substate currently put in relation with MbCO molecules having the distal histidine out of the heme pocket) is largely enhanced during the dehydration process. However, after rehumidification its population is largely decreased with respect to the values obtained, at similar water content, during the first dehydration run.  (+info)

Cell surface analysis techniques: What do cell preparation protocols do to cell surface properties? (4/770)

Cell surface analysis often requires manipulation of cells prior to examination. The most commonly employed procedures are centrifugation at different speeds, changes of media during washing or final resuspension, desiccation (either air drying for contact angle measurements or freeze-drying for sensitive spectroscopic analysis, such as X-ray photoelectron spectroscopy), and contact with hydrocarbon (hydrophobicity assays). The effects of these procedures on electrophoretic mobility, adhesion to solid substrata, affinity to a number of Sepharose columns, structural integrity, and cell viability were systematically investigated for a range of model organisms, including carbon- and nitrogen-limited Psychrobacter sp. strain SW8 (glycocalyx-bearing cells), Escherichia coli (gram-negative cells without a glycocalyx), and Staphylococcus epidermidis (gram-positive cells without a glycocalyx). All of the cell manipulation procedures severely modified the physicochemical properties of cells, but with each procedure some organisms were more susceptible than others. Considerable disruption of cell surfaces occurred when organisms were placed in contact with a hydrocarbon (hexadecane). The majority of cells became nonculturable after air drying and freeze-drying. Centrifugation at a high speed (15,000 x g) modified many cell surface parameters significantly, although cell viability was considerably affected only in E. coli. The type of washing or resuspension medium had a strong influence on the values of cell surface parameters, particularly when high-salt solutions were compared with low-salt buffers. The values for parameters obtained with different methods that allegedly measure similar cell surface properties did not correlate for most cells. These results demonstrate that the methods used to prepare cells for cell surface analysis need to be critically investigated for each microorganism so that the final results obtained reflect the nature of the in situ microbial cell surface as closely as possible. There is an urgent need for new, reliable, nondestructive, minimally manipulative cell surface analysis techniques that can be used in situ.  (+info)

Regulation of the hepatocyte cell cycle by type I collagen matrix: role of cyclin D1. (5/770)

Rat hepatocytes adherent to a rigid film of type I collagen will spread and enter S phase, while those attached to collagen gel or a dried collagen substrate remain round and quiescent. The current studies were initiated to determine the mechanism by which these different substrates differentially influence cell cycle progression. Cyclin D1 mRNA and protein expression and associated kinase activity was low on dried collagen relative to collagen film. In contrast, cyclin E and cdk2 protein levels were similar on the two substrates. Although cyclin E and cdk2 were present, cells on dried collagen lacked cdk2 kinase activity. p27 protein levels did not differ between dried collagen and film, but more p27 was associated with cdk2 in cells on dried collagen than those on collagen film. Cyclin D1 expression on collagen film was inhibited by cytochalasin D and exoenzyme C3, suggesting a role for the GTP-binding protein, Rho, in regulating cyclin D1 expression. Cyclin D1 over-expression induced hepatocytes into S phase in the absence of cell shape change on dried collagen or collagen gel. These results demonstrate a novel, substrate-dependent mechanism for cyclin D1 expression in hepatocytes, and also demonstrate that cyclin D1 over-expression allows shape-independent S phase entry.  (+info)

Isotope dilution spaces of mice injected simultaneously with deuterium, tritium and oxygen-18. (6/770)

The isotope dilution technique for measuring total body water (TBW), and the doubly labelled water (DLW) method for measuring energy expenditure, are both sensitive to small variations in the ratio of the hydrogen to oxygen-18 dilution space. Since the dilution space ratio varies between individuals, there has been much recent debate over what causes this variability (i.e. physiological differences between individuals or analytical error in the isotope determinations), and thus which values (individual or a population mean dilution space ratio) should be employed for TBW and DLW calculations. To distinguish between physiological and analytical variability, we injected 15 non-reproductive and 12 lactating mice (Mus musculus, outbred MF1) simultaneously with deuterium, tritium and oxygen-18. The two hydrogen labels were administered and analysed independently, therefore we expected a strong correlation between dilution space ratios based on deuterium and tritium if most of the variation in dilution spaces was physiological, but only a weak correlation if most of the variation was analytical. Dilution spaces were significantly influenced by reproductive status. Dilution spaces expressed as a percentage of body mass averaged 15.7 % greater in lactating mice than in non-reproductive mice. In addition, the hydrogen tracer employed had a significant effect (deuterium spaces were 2.0 % larger than tritium spaces). Deuterium and tritium dilution spaces, expressed as a percentage of body mass, were highly correlated. Dilution space ratios ranged from 0.952 to 1. 146 when using deuterium, and from 0.930 to 1.103 when using tritium. Dilution space ratios based on deuterium and tritium were also highly correlated. Comparison of standard deviations of the dilution space ratio based on deuterium in vivo and in vitro indicated that only 4.5 % of the variation in the dilution space ratios observed in the mice could be accounted for by analytical variation in the deuterium and oxygen-18 analyses. Although our results include data which were outside the limits previously regarded as biologically possible, the correlations that we detected strongly suggest that variation in the observed dilution space ratio was mostly physiological rather than analytical.  (+info)

Active Fe-containing superoxide dismutase and abundant sodF mRNA in Nostoc commune (Cyanobacteria) after years of desiccation. (7/770)

Active Fe-superoxide dismutase (SodF) was the third most abundant soluble protein in cells of Nostoc commune CHEN/1986 after prolonged (13 years) storage in the desiccated state. Upon rehydration, Fe-containing superoxide disumutase (Fe-SOD) was released and the activity was distributed between rehydrating cells and the extracellular fluid. The 21-kDa Fe-SOD polypeptide was purified, the N terminus was sequenced, and the data were used to isolate sodF from the clonal isolate N. commune DRH1. sodF encodes an open reading frame of 200 codons and is expressed as a monocistronic transcript (of approximately 750 bases) from a region of the genome which includes genes involved in nucleic acid synthesis and repair, including dipyrimidine photolyase (phr) and cytidylate monophosphate kinase (panC). sodF mRNA was abundant and stable in cells after long-term desiccation. Upon rehydration of desiccated cells, there was a turnover of sodF mRNA within 15 min and then a rise in the mRNA pool to control levels (quantity of sodF mRNA in cells in late logarithmic phase of growth) over approximately 24 h. The extensive extracellular polysaccharide (glycan) of N. commune DRH1 generated superoxide radicals upon exposure to UV-A or -B irradiation, and these were scavenged by SOD. Despite demonstrated roles for the glycan in the desiccation tolerance of N. commune, it may in fact be a significant source of damaging free radicals in vivo. It is proposed that the high levels of SodF in N. commune, and release of the enzyme from dried cells upon rehydration, counter the effects of oxidative stress imposed by multiple cycles of desiccation and rehydration during UV-A or -B irradiation in situ.  (+info)

Structural characterization of the released polysaccharide of desiccation-tolerant Nostoc commune DRH-1. (8/770)

The structure of the viscous extracellular polysaccharide (glycan) of desiccation-tolerant Nostoc commune DRH-1 was determined through chromatographic and spectroscopic methods. The polysaccharide is novel in that it possesses a 1-4-linked xylogalactoglucan backbone with D-ribofuranose and 3-O-[(R)-1-carboxyethyl]-D-glucuronic acid (nosturonic acid) pendant groups. The presence of D-ribose and nosturonic acid as peripheral groups is unusual, and their potential roles in modulating the rheological properties of the glycan are discussed. Nosturonic acid was present in the glycans of N. commune from diverse geographic locations, suggesting that this uronic acid is an integral component of this cosmopolitan anhydrophile.  (+info)

Late Embryogenesis Abundant proteins (LEAPs) comprise several diverse protein families and are mostly involved in stress tolerance. Most of LEAPs are intrinsically disordered and thus poorly functionally characterized. LEAPs have been classified and a large number of their physico-chemical properties have been statistically analyzed. LEAPs were previously proposed to be a subset of a very wide family of proteins called hydrophilins, while a domain called WHy (Water stress and Hypersensitive response) was found in LEAP class 8 (according to our previous classification). Since little is known about hydrophilins and WHy domain, the cross-analysis of their amino acids physico-chemical properties and amino acids usage together with those of LEAPs helps to describe some of their structural features and to make hypothesis about their function. Physico-chemical properties of hydrophilins and WHy domain strongly suggest their role in dehydration tolerance, probably by interacting with water and small polar
Briefly, eyes and lids from mice in each group (n = 3 per group) were surgically excised and embedded in OCT compound (VWR, Swannee, GA) and flash frozen in liquid nitrogen. Sagittal 8-μm sections were cut with a cryostat (HM 500; Micron, Waldorf, Germany) and placed on glass slides that were stored at −80°C. They were fixed with either cold acetone (involucrin, Sprr-2, and Tg-1) at −20°C for 5 minutes or with methanol (Sprr-1a, and Muc5AC+Sprr-1a) at 4°C for 5 minutes and then permeabilized with PBS containing 0.1% Triton X-100 for 10 minutes. After blocking with 20% normal goat serum in PBS for 60 minutes (except for involucrin and Muc5AC where 20% horse normal serum was used), primary polyclonal antibodies (dilution 1:100 for all of them, except for involucrin, which was 1:20) were applied, and the sections were incubated for 1 hour at RT. When dual labeling was intended, Alexa-Fluor 488-conjugated goat anti-rabbit IgG and Alexa-Fluor 633-conjugated donkey anti-goat IgG (1:300) ...

Evolutionary changes in traits involved in both ecological divergence and mate choice may produce reproductive isolation and speciation. However, there are few examples of such dual traits, and the genetic and molecular bases of their evolution have not been identified. We show that methyl-branched cuticular hydrocarbons (mbCHCs) are a dual trait that affects both desiccation resistance and mate choice in Drosophila serrata. We identify a fatty acid synthase mFAS (CG3524) responsible for mbCHC production in Drosophila and find that expression of mFAS is undetectable in oenocytes (cells that produce CHCs) of a closely related, desiccation-sensitive species, D. birchii, due in part to multiple changes in cis-regulatory sequences of mFAS. We suggest that ecologically influenced changes in the production of mbCHCs have contributed to reproductive isolation between the two species. ...

One area that is critical to the recovery process is rehydrating. Rehydrating not only replenishes fluids lost during exercise, but it also aids in replenishing the electrolytes that were also lost. Keep in mind: drinking too much too fast can degrade the potential gains of the workout. Heres why: over time your body has developed a strong immune system that helps repair itself when it is under the stresses of exercise. Therefore, naturally, your body begins repairing itself, slowly rehydrating, and continuing to hydrate throughout the day..

Molecular studies of late embryogenesis and seed development have emphasized differential gene expression as a means of identifying discrete stages of embryogenesis. Little has been done to identify factors that regulate the length of a given developmental stage or the degree of overlap between adjacent developmental programs. We designed a genetic screen to identify mutations that disrupt late embryo development in Arabidopsis without loss of hormonal responses. One such mutation, fusca3 (fus3), alters late embryo functions, such as the establishment of dormancy and desiccation tolerance, and reduces storage protein levels. fus3 cotyledons bear trichomes, and their ultrastructure is similar to that of leaf primordia. Immature fus3 embryos enter germinative development, and the shoot apical meristems develop leaf primordia before seed desiccation begins. The cotyledons resemble leaf primordia, yet retain some cotyledon characteristics; thus, cotyledon- and leaf-specific functions are expressed ...

I have to admit that I enjoy figuring out new ways to use things. Ive never thought much of the lowly dryer sheet (sometimes referred to as a fabric softener sheet), but have come to learn that it can do a lot of wonderful things - even after its been used. You may be surprised at the wide variety of ways that used dryer sheets can be reused to still be useful even after doing a dryer run.

So before you throw that dryer sheet into the trash, see if any of the following 50 ways to reuse dryer sheets is one that makes sense for you.. Its important to note that all of the following suggestions can be done with used dryer sheets. Because they have already gone through the dryer once, the fragrance they give off wont be nearly as strong as new dryer sheets, but that doesnt mean that it doesnt have any fragrance at all (most will still retain quite a bit after a run ...

I thought this article at Howstuffworks was appropriate just after the all day drinking fest that is St. Patricks Day for many.. According to the article, a hangover from a heavy night (and/or day) of drinking is mainly due to dehydration.. The dehydration process begins with a chemical reaction in the brain; specifically the pituitary gland. This reaction causes less vasopressin to be released from the pituitary gland, which in turn causes the kidneys to send water directly into the bladder (rather than reabsorbing it).. So why do hangovers cause headaches? Apparently the massive amount of dehydration by the morning causes the bodys organs to steal water from the brain.. According to the article, this causes the brain to decrease in size and pull on the membranes that connect the brain to the skull, resulting in pain. This cannot be good for neuronal health!. Based on this information it seems that the best way to avoid a hangover is to drink plenty of water along with those heavy booze. ...

The thermal stability properties of poly (ethylene-co-vinyl acetate) composites have been studied in support of our core programmes in materials qualification and life assessment. The material is used as a binder phase for boron particles in highly filled (70 wt %) composites. Our studies show that the uncured resin readily accumulates acetic acid through hydrolysis of the pendent acetate groups which alters the acidity (pH) of the material. Thermal desorption studies in combination with gas-chromatography-mass spectrometry show that the resin readily evolves acetic acid when thermally aged to temperatures up to 75°C. Gel Permeation Chromatography (GPC) suggests that thermal ageing induces a gradual reduction in resin molecular weight and confirms the susceptibility of the material to chain scission. Heating at elevated temperatures in excess of 300oC is required to induce significant changes in the carbon skeleton through deacetylation and dehydration processes and the production of ...
Late-embryogenesis is characterised by the accumulation of large amounts of storage proteins, the acquisation of desiccation tolerance and the induction of dormancy. Genetic studies demonstrated that these processes are controlled by the transcription factors LEC1, FUS3 and ABI3. The present study was focused on the molecular characterisation of FUS3, LEC1 and ABI3 in an attempt to clarify the interaction of these transcription factors and their role in late-embryogenesis. To investigate the potential interaction between FUS3, ABI3 and LEC1 and their function on the activation of seed-storage protein promoters a transient expression system in tobacco protoplasts was established. With the help of this system it was shown that the FUS3- and ABI3-gene products can induce both independently and dependently of each other storage protein promoters. The FUS3 and ABI3 mediated increase in activity of storage protein promoters could be strongly reduced when a conserved sequence element, the RY motif, was ...

LEA proteins are synthesized late during embryogenesis in plant seed development. Structurally related proteins have also been found in vegetative plant tissues under various stress conditions and in desiccation tolerant invertebrates and microbes. They thus seem to be universal dehydration stress proteins in living cells, with the exception of vertebrates. Their biological functions in stress tolerance, however, are unclear. Most of these proteins have no stable secondary structure in solution, i.e. they belong to the large group of intrinsically disordered proteins (IDPs). We are concentrating our efforts on the largest LEA protein family (Pfam LEA_4) that has 18 members. We produce proteins of interest recombinantly in E. coli and use mainly fluorescence, far-UV circular dichroism (CD) and Fourier-transform infrared (FTIR) spectroscopy for structural and functional characterization. To study the interactions with membranes, we use artificial lipid vesicles (liposomes) that can be produced ...
I am starting a job at a new place. At the old shop, we crate dried almost every dog. At my new job, I have to dry dogs by hand. They use high velocity blowers and stand dryers. I have never used a stand dryer before. What do I need to know? . - Kelly P. Well Kelly, I am happy to hear that you are going to learn some new things! I think you will find that these methods of drying will help you achieve a faster, more beautiful result, which could equal more pay and more tips!. Remember to be patient with yourself and the dog. Stand dryers can be tedious to master and high velocity dryers are scary, especially around the head, when you are not accustomed to the dog handling skills required. At first, these methods may actually add time to your grooming service but they will most likely save you time in the long run..

Ecophysiology. Holmlund, Helen [1], Pratt, Brandon [2], Jacobsen, Anna [3], Davis, Stephen [4], Pittermann, Jarmila [1]. High-resolution computed tomography reveals dynamics of desiccation and rehydration in a desiccation-tolerant fern.. Desiccation-tolerant (DT) plants can completely desiccate to less than 10% water content (-100 MPa) and subsequently recover all function upon rehydration. These remarkable plants are aptly named resurrection plants for their ability to recover from apparent death. Resurrection plants often thrive in dry niches, including rocky outcrops with shallow soil. For instance, Pentagramma triangularis is a DT fern native to the semi-arid chaparral ecosystem of southern California, where it survives extended seasonal drought in the desiccated, deep dormancy state. Most DT plants are small, non-vascular plants, including bryophytes and fern gametophytes. Vascular DT plants face several additional challenges over non-vascular plants such as 1) desiccating tissues without ...
Certain organisms are able to survive almost complete loss of their internal water, entering a state of suspended animation called anhydrobiosis. When water becomes available again, the organism revives and resumes its normal activities. These organisms have been called sleeping beauties since they appear not to age during dormancy (Hengherr et al., 2008; Ricci and Covino, 2005). Desiccation tolerance is relatively widespread among prokaryotes and unicellular eukaryotes [e.g. bakers yeast, Saccharomyces cerevisiae (Potts, 1994)], but is less common in multicellular eukaryotes, being exclusive to some life stages of plants (mainly seeds and pollen), a number of resurrection plants, and some invertebrates, with well-known examples among the arthropods, tardigrades, nematodes and bdelloid rotifers (Alpert, 2006; Clegg, 2001).. In some organisms, an increase in levels of di- and oligosaccharides, especially the non-reducing sugars trehalose (in animals) and sucrose (in plants), has been ...
Background: Nematodes are the dominant soil animals in Antarctic Dry Valleys and are capable of surviving desiccation and freezing in an anhydrobiotic state. Genes induced by desiccation stress have been successfully enumerated in nematodes; however we have little knowledge of gene regulation by Antarctic nematodes which can survive multiple environmental stresses. To address this problem we investigated the genetic responses of a nematode species, Plectus murrayi, that is capable of tolerating Antarctic environmental extremes, in particular desiccation and freezing. In this study, we provide the first insight into the desiccation induced transcriptome of an Antarctic nematode through cDNA library construction and suppressive subtractive hybridization. Results: We obtained 2,486 expressed sequence tags (ESTs) from 2,586 clones derived from the cDNA library of desiccated P. murrayi. The 2,486 ESTs formed 1,387 putative unique transcripts of which 523 (38%) had matches in the model-nematode Caenorhabditis
Mango (Mangifera indica L.) seed is recalitrant which taken from ripened fruits con,ained as high as 69.2 C75.5% moisture content (The moisture content of embryonic axis is 73.8 C86.3%). When seeds were naturally dried for 8 days, the moisture content declined to 39.1% (in embryonic axis the moisture content declined to 46.5%) and the viability of seeds completely lost. Embryonic axis lost water slower than whole seed because of the prevention of desiccation by the large cotyledons. During natural desiccation, the conductivity of leachate increased rapidly from 2.2 ̦ cm-1 g-1 (the same unit below) to 56.7, whereas the activities of dehydrogenase and acid phosphatase decreased drastically. When seeds were rapidly dried for 42 hours, the moisture content declined from 75.5 to 29.9%, the conductivity of leachate increased from 1.8 to 36.9 and the percentage germination changed from 100% to 10%. Desiccation damaged the cell membrane and decreased the activities of enzymes. Rapid drying was better ...
Salmonella can survive for long periods under extreme desiccation conditions. This stress tolerance poses a risk for food safety, but relatively little is known about the molecular and cellular regulation of this adaptation mechanism. To determine the genetic components involved in Salmonellas cellular response to desiccation, we performed a global transcriptomic analysis comparing S. enterica serovar Typhimurium cells equilibrated to low water activity (aw 0.11) and cells equilibrated to high water activity (aw 1.0). The analysis revealed that 719 genes were differentially regulated between the two conditions, of which 290 genes were up-regulated at aw 0.11. Most of these genes were involved in metabolic pathways, transporter regulation, DNA replication/repair, transcription and translation, and, more importantly, virulence genes. Among these, we decided to focus on the role of sopD and sseD. Deletion mutants were created and their ability to survive desiccation and exposure to aw 0.11 was compared to
Desiccation stress can determine the upper distribution limits and could enhance the uptake of nitrate and ammonium of intertidal algal species. Emersion following desiccation might stimulate several aspects of metabolism. Upper shore species may exhibit greater stimulation of N uptake following desiccation and achieve maximum uptake at higher desiccation levels. The objective of this study was to determine whether Porphyra species from different vertical elevations respond differently to the desiccation stress, in terms of nitrate uptake and growth. The intertidal species (Porphyra umbilicalis) and subtidal species (P. amplissima) were utilized in this study. Both species were cultivated at 100-150 umol m-2 s-1 light intensities, 500 uM nitrate concentration and 10 C (P. umbilicalis). Porphyra amplissima was cultivated at 15 C for three days, and P. umbilicalis was cultivated at 10 C for three weeks at a photoperiod of 12:12h L:D. Samples were exposed to air for 0, 30 min (30-50% water loss) ...

Several bacterial species have been shown to accumulate DNA damages upon desiccation. Deinococcus radiodurans is extremely resistant to ionizing radiation. The functions necessary to survive ionizing radiation are also necessary to survive prolonged desiccation.[3] Radiation resistance is considered to be an incidental consequence of the organisms evolutionary adaptation to dehydration, a common physiological stress in nature.[3] The chromosomal DNA from desiccated D. radiodurans revealed increased DNA double-strand breaks.[4] DNA double-strand breaks are repaired principally by a RecA-dependent recombination process that requires the presence of two genome copies.[4] By this process D. radiodurans can survive thousands of double-strand breaks per cell.[4] Mycobacterium smegmatis mutant strains that are deficient in the ability to repair double-strand breaks by the non-homologous enjoining (NHEJ) pathway are more sensitive to prolonged desiccation during stationary phase than wild-type ...

UNDERSTANDING how adaptation proceeds in a population is important for predicting natural responses to impending stress that will challenge the adaptive potential of many species. Climate stress is a timely example: our ability to predict and respond to climate change effects on natural populations requires relevant models of how evolution proceeds, backed up by empirical evidence.. Aridity is one climate-imposed stress likely to increase in parts of the world as climate change proceeds. Many areas that currently experience reasonable rainfall are projected to become drier over the coming decades (Dai 2012), and some are already showing significant reductions in rainfall (e.g., southwestern Australia: Delworth and Zeng 2014). Dry conditions typically impose water balance stress on organisms, and, when there is no behavioral escape possible, the only opportunities for survival are tolerance or adaptation (Franks and Hoffmann 2012).. The potential for adaptation to desiccation stress varies ...
This manuscript introduces a unified mathematical framework to replicate both desiccation-induced and hydraulic fracturing in low-permeable unsaturated porous materials observed in experiments. The unsaturated porous medium is considered as a three-phase solid-liquid-gas effective medium of which each constituent occupies a fraction of the representative elementary volume. As such, an energy-minimization-based phase-field model (PFM) is formulated along with the Biots poroelasticity theory to replicate the sub-critical crack growth in the brittle regime. Unlike hydraulic fracturing where the excess pore liquid pressure plays an important role at the onset and propagation of cracks, desiccation cracks are mainly driven by deformation induced by water retention. Therefore, the wettability of the solid skeleton may affect the evolution of the capillary pressure (suction) and change the path-dependent responses of the porous media. This air-water-solid interaction may either hinder or enhance the cracking

This chapter describes the approaches and results of comparative genomic analysis of Deinococcaceae with an emphasis on stress response systems and their impact on contemporary models of extreme ionizing radiation (IR) resistance. Clusters of orthologous genes (COGs) are the most useful framework for comparative genomics. Researchers assigned the proteins of D. deserti to tdCOGs, which has reinforced the view of the proliferation of Deinococcaceae genes involved in stress response pathways. Gene expression in D. radiodurans recovering from high-dose irradiation has been investigated using whole genome microarrays, which identified hundreds of D. radiodurans genes that were upregulated during recovery. The radiation/desiccation response (RDR) regulon is dominated by DNA repair genes, including the recombinational repair proteins RecA and RecQ, the mismatch repair proteins MutS and MutL, and the UvrB and UvrC proteins, which are involved in nucleotide excision repair. The prospect of comparative genomics

Interpretive Summary: The rate at which cells are exposed to liquid nitrogen temperatures determines whether lethal ice crystals form. In very small systems (1 to a few cells), sufficiently fast cooling is relatively easy to achieve. For most plant germplasm, propagule size is about 500,000 cells and this geometry limits how quickly heat can be dissipated. This paper examines how mechanisms of heat transfer (convection and conduction) and variables affecting thermal mass affect cooling rate of a desiccation-sensitive embryo. By slightly adjusting water content and exploiting convective cooling, cooling rates of hundreds of degrees (C) per sec can be achieved. Technical Abstract: The present study investigated the rate of temperature change within axes of Poncirus trifoliata during cooling and warming by ...

Gas Dehydration processes utilize glycol solvents to remove water from wet natural gas to meet pipeline quality specifications or condition the gas for condensate liquids removal. The wet gas is contacted with lean glycol in the contactor tower. The rich glycol then flows to a regenerator, where heat separates the used glycol and the water, regenerating the glycol for re-use. The water vapour exits the top of the regenerator to atmosphere while the lean glycol is recirculated back to the contactor in a recirculating loop.. Through this process, the Gas Plant can achieve:. ...

I should also mention that Im not too picky when it comes to real meat vs meat meal. Meat meal gets a bad rap because its not pure meat (theres skin and bone in there as well), but its helpful to keep in mind that pure meat is mostly water which evaporates during the dehydration process, so in reality the meat that you saw at the top of the ingredients list (which uses pre-dehydration weights) should really be several spots lower. On the other hand, meat meals are powders to begin with so theyre not affected by dehydration as much. That being said, its nice to see real meat as a first ingredient, but it should directly be followed by a chicken/salmon/duck/specific-animal meal -- plain ol meat meal on the bag doesnt cut it; I like to know what protein source its coming from. Finally, one thing I try to avoid is meat byproduct meal. This is almost like a meat meal but with heads, feet, and guts thrown in the mix.

When the tardigrade begins to dry out, its body activates its lifesaving TDPs. These proteins protect the tardigrade in much the same way that trehalose sugar protects the brine shrimp, Dr. Boothby said. The proteins encapsulate its molecular components in a glasslike matrix within the body that preserves them during the drying process.. The glass is coating the molecules inside of the tardigrade cells, keeping them intact, said Dr. Boothby said. This slows down the tardigrades metabolism, allowing it to remain in a suspended state until it is rehydrated. When they add water, the proteins melt into the liquid, and the molecules within the tardigrade are free to carry out their functions again.. Dr. Boothby said that trehalose sugar and TDPs were an example of convergent evolution, where nature has found two different ways to protect organisms from desiccation. ...

Water on its own can aggravate watery diarrhea in some instances. It may not be absorbed into the body due to the lack of electrolytes. While fluid replenishment is essential in diarrhea, especially when the stool is very watery, drinking water alone may not be your best option. An oral rehydrating solution (ORS) should be the fluid of choice. It can be made at home with clean water, sugar and salt but ideally you should opt for a commercial ORS which is available in most supermarkets and pharmacies.. Commercial ORS is usually in the form of a sachet containing granules that can be diluted in water. An ORS has the correct concentration of electrolytes which helps water to be absorbed into the body rather than remaining in the bowels where it exacerbates the watery diarrhea. Furthermore the electrolytes help with reducing dehydration. The ORS should be used exactly as directed. Mix well to ensure that the granules adequately dissolve in the water.. ...

Good old H2O is critical for rehydrating when the body experiences fluid loss, such as when we sweat. Even though many gyms like to keep pricey sports drinks and protein shakes stocked on their shelves, most of the time, water will do the trick just fine. Shoot to sip seven to 10 ounces of fluid every 10 to 20 minutes during exercise to stay properly hydrated. If youre working out for longer than an hour or doing a particularly intense exercise (like running a marathon or participating in a tough training session), you will probably need to replace electrolytes too-this is where a sports drink or electrolyte-enhanced water comes in handy. However its also important to be wary of overhydration: Too much water can lead to hyponatremia, which is when excess water in our bodies dilutes the sodium content of our blood. It is most often caused by long duration exercise and either drinking fluid at a rate that is more than fluid losses or only replacing fluid losses with hypotonic fluids like ...
