Cavitation fatigue. Embolism and refilling cycles can weaken the cavitation resistance of xylem. (1/167)

Although cavitation and refilling cycles could be common in plants, it is unknown whether these cycles weaken the cavitation resistance of xylem. Stem or petiole segments were tested for cavitation resistance before and after a controlled cavitation-refilling cycle. Cavitation was induced by centrifugation, air drying of shoots, or soil drought. Except for droughted plants, material was not significantly water stressed prior to collection. Cavitation resistance was determined from "vulnerability curves" showing the percentage loss of conductivity versus xylem pressure. Two responses were observed. "Resilient" xylem (Acer negundo and Alnus incana stems) showed no change in cavitation resistance after a cavitation-refilling cycle. In contrast, "weakened" xylem (Populus angustifolia, P. tremuloides, Helianthus annuus stems, and Aesculus hippocastanum petioles) showed considerable reduction in cavitation resistance. Weakening was observed whether cavitation was induced by centrifugation, air dehydration, or soil drought. Observations from H. annuus showed that weakening was proportional to the embolism induced by stress. Air injection experiments indicated that the weakened response was a result of an increase in the leakiness of the vascular system to air seeding. The increased air permeability in weakened xylem could result from rupture or loosening of the cellulosic mesh of interconduit pit membranes during the water stress and cavitation treatment.  (+info)

Phenylcoumaran benzylic ether and isoflavonoid reductases are a new class of cross-reactive allergens in birch pollen, fruits and vegetables. (2/167)

We investigated the biochemical function of the birch pollen allergen Bet v 6 and its role in the IgE-cross-reactivity between birch pollen and plant foods, and characterized Pyr c 5, a Bet v 6-related food allergen, from pear; the proteins were expressed as His-Tag fusion proteins in Eschershia coli and purified by Ni-chelate affinity chromatography under native conditions. Nonfusion proteins were obtained by factor Xa protease treatment. The highest degree of amino-acid sequence identity of Pyr c 5 and Bet v 6 was found with a plant protein related to a defense mechanism, which we have named phenylcoumaran benzylic ether reductase (PCBER) based on its ability to catalyze the NADPH-dependent reduction of 8-5' linked lignans such as dehydrodiconiferyl alcohol to give isodihydrodehydrodiconiferyl alcohol. Enzymatic assays with recombinant Pyr c 5 and Bet v 6 showed PCBER catalytic activity for both recombinant allergens. Both Pyr c 5 and Bet v 6 allergens had similar IgE binding characteristics in immunoblotting and enzyme allergosorbent tests (EAST), and bound IgE from 10 sera of birch-pollen-allergic patients including six pear-allergic subjects. EAST inhibition experiments with Pyr c 5 as the solid phase antigen suggested that homologous allergens may be present in many vegetable foods such as apple, peach, orange, lychee fruit, strawberry, persimmon, zucchini (courgette), and carrot. In extracts of pear, apple, orange, and persimmon, the presence of proteins of approximately 30-35 kDa containing Bet v 6 cross-reactive epitopes was demonstrated with two Bet v 6-specific monoclonal antibodies. Recombinant Pyr c 5 triggered a strong, dose-dependent mediator release from basophils of a pear-allergic subject, suggesting that Pyr c 5 has the potential to elicit type I allergic reactions.  (+info)

Comparative analysis of pollen counts of Corylus, Alnus and Betula in Szczecin, Warsaw and Lublin (2000-2001). (3/167)

The aim of the study was to compare the airborne concentrations of allergenic pollen produced by three early flowering tree taxa (Corylus, Alnus, Betula) in the cities of Warsaw (central Poland), Lublin (eastern Poland) and Szczecin (western Poland) during the years 2000-2001. Measurements were performed by the volumetric method. Pollen seasons were defined as the periods in which 95% of the total catch occurred. The highest concentration and annual pollen count of Corylus was measured in Lublin in both seasons, while the highest annual pollen counts of Alnus and Betula were noted in Warsaw, where the annual pollen count of Betula in 2001 was four times higher than in 2000 and equalled 5,376 grains in m3 per 24 h. Significant differences in the pollen count of the examined taxa were observed between two seasons: the pollen count of Corylus was higher in 2000 than in 2001, while for Alnus and Betula the opposite was the case. The longest pollen seasons were observed at low annual pollen counts for the pollen of Corylus. Results of the study reveal significant differences between the seasons and the cities. The differences concern the dates of the appearance of pollen grains in the air, the duration of the presence of sporomorphs and the maximum concentrations in particular seasons. The pollen counts of alder, birch and hazel trees are determined by the weather, diversity of local flora and specific rhythm of pollination of particular taxa.  (+info)

Mast cell alpha-chymase reduces IgE recognition of birch pollen profilin by cleaving antibody-binding epitopes. (4/167)

In sensitized individuals birch pollen induces an allergic response characterized by IgE-dependent mast cell degranulation of mediators, such as alpha-chymase and other serine proteases. In birch and other plant pollens, a major allergen is profilin. In mammals, profilin homologues are found in an intracellular form bound to cytoskeletal or cytosolic proteins or in a secreted form that may initiate signal transduction. IgE specific to birch profilin also binds human profilin I. This cross-reactivity between airborne and endogenous proteins may help to sustain allergy symptoms. The current work demonstrates that cultured mast cells constitutively secrete profilin I, which is susceptible to degranulation-dependent proteolysis. Coincubation of chymase-rich BR mastocytoma cells with Ala-Ala-Pro-Phe-chloromethylketone (a chymase inhibitor) blocks profilin cleavage, which does not occur in degranulated HMC-1 mast cells, which are rich in tryptase, but chymase deficient. These data implicate chymase as the serine protease cleaving secreted mast cell profilin. Sequencing of chymase-cleaved profilins reveals hydrolysis at Tyr(6)-Val(7) and Trp(35)-Ala(36) in birch profilin and at Trp(32)-Ala(33) in human profilin, with all sites lying within IgE-reactive epitopes. IgE immunoblotting studies with sera from birch pollen-allergic individuals demonstrate that cleavage by chymase attenuates binding of birch profilin to IgE. Thus, destruction of IgE-binding epitopes by exocytosed chymase may limit further mast cell activation by this class of common plant allergens, thereby limiting the allergic responses in sensitized individuals.  (+info)

Morphological, cytogenetic, and molecular evidence for introgressive hybridization in birch. (5/167)

Extensive morphological variation of tetraploid birch (Betula pubescens) in Iceland is believed to be due to gene flow from diploid dwarf birch (B. nana) by means of introgressive hybridization. A combined morphological and cytogenetic approach was used to investigate this phenomenon in two geographically separated populations of natural birch woodland in Iceland. The results not only confirmed introgressive hybridization in birch, but also revealed bidirectional gene flow between the two species via triploid interspecific hybrids. The populations showed continuous morphological variation connecting the species, but karyotypically they consisted of only three types of plants: diploids, triploids, and tetraploids. No aneuploids were found. Some of the tetraploid plants had B. pubescens morphology as expected, but most of them had intermediate characters. Most of the diploid plants were B. nana, but some were intermediates and a few had B. pubescens morphology. The triploid plants were either intermediates or they resembled one of the two species. Similar introgressive variation was observed among the diploid and triploid progeny of open-pollinated B. nana in a garden. Birch samples including field plants and artificial hybrids were further examined using a molecular method based on genomic Southern hybridization. The experiments verified introgression at the DNA level.  (+info)

Leaf structural and photosynthetic characteristics, and biomass allocation to foliage in relation to foliar nitrogen content and tree size in three Betula species. (6/167)

Young trees 0.03-1.7 m high of three coexisting Betula species were investigated in four sites of varying soil fertility, but all in full daylight, to separate nutrient and plant size controls on leaf dry mass per unit area (MA), light-saturated foliar photosynthetic electron transport rate (J) and the fraction of plant biomass in foliage (F(L)). Because the site effect was generally non-significant in the analyses of variance with foliar nitrogen content per unit dry mass (N(M)) as a covariate, N(M) was used as an explaining variable of leaf structural and physiological characteristics. Average leaf area (S) and dry mass per leaf scaled positively with N(M) and total tree height (H) in all species. Leaf dry mass per unit area also increased with increasing H, but decreased with increasing N(M), whereas the effects were species-specific. Increases in plant size led to a lower and increases in N(M) to a greater FL and total plant foliar area per unit plant biomass (LAR). Thus, the self-shading probably increased with increasing N(M) and decreased with increasing H. Nevertheless, the whole-plant average M(A), as well as M(A) values of topmost fully exposed leaves, correlated with N(M) and H in a similar manner, indicating that scaling of MA with N(M) and H did not necessarily result from the modified degree of within-plant shading. The rate of photosynthetic electron transport per unit dry mass (J(M)) scaled positively with N(M), but decreased with increasing H and M(A). Thus, increases in M(A) with tree height and decreasing nitrogen content not only resulted in a lower plant foliar area (LAR = F(L)/M(A)), but also led to lower physiological activity of unit foliar biomass. The leaf parameters (J(M), N(M) and M(A)) varied threefold, but the whole-plant characteristic FL varied 20-fold and LAR 30-fold, indicating that the biomass allocation was more plastically adjusted to different plant internal nitrogen contents and to tree height than the foliar variables. Our results demonstrate that: (1) tree height and N(M) may independently control foliar structure and physiology, and have an even greater impact on biomass allocation; and (2) the modified within-plant light availabilities alone do not explain the observed patterns. Although there were interspecific differences with respect to the statistical significance of the relationships, all species generally fit common regressions. However, these differences were consistent, and suggested that more competitive species with inherently larger growth rates also more plastically respond to N and H.  (+info)

Hydrogen peroxide activates cell death and defense gene expression in birch. (7/167)

The function of hydrogen peroxide (H(2)O(2)) as a signal molecule regulating gene expression and cell death induced by external stresses was studied in birch (Betula pendula). Ozone (O(3)), Pseudomonas syringae pv syringae (Pss), and wounding all induced cell death of various extents in birch leaves. This was temporally preceded and closely accompanied by H(2)O(2) accumulation at, and especially surrounding, the lesion sites. O(3) and Pss, along with an artificial H(2)O(2) producing system glucose (Glc)/Glc oxidase, elicited elevated mRNA levels corresponding to genes encoding reactive oxygen species detoxifying enzymes, Pal, Ypr10, and mitochondrial phosphate translocator 1. In addition to the regulation of gene expression, Glc/Glc oxidase also induced endogenous H(2)O(2) production in birch leaves, accompanied by cell death that resembled O(3) and Pss damage. Wound-induced gene expression differed from that induced by O(3) and Pss. Thus, it appears that at least two separate defense pathways can be activated in birch leaves by stress factors, even though the early H(2)O(2) accumulation response is common among them all.  (+info)

Xylem ray parenchyma cells in boreal hardwood species respond to subfreezing temperatures by deep supercooling that is accompanied by incomplete desiccation. (8/167)

It has been accepted that xylem ray parenchyma cells (XRPCs) in hardwood species respond to subfreezing temperatures either by deep supercooling or by extracellular freezing. Present study by cryo-scanning electron microscopy examined the freezing responses of XRPCs in five boreal hardwoods: Salix sachalinensis Fr. Schmit, Populus sieboldii Miq., Betula platyphylla Sukat. var japonica Hara, Betula pubescens Ehrh., and red osier dogwood (Cornus sericea), in which XRPCs have been reported to respond by extracellular freezing. Cryo-scanning electron microscopy observations revealed that slow cooling of xylem to -80 degrees C resulted in intracellular freezing in the majority of XRPCs in S. sachalinensis, an indication that these XRPCs had been deep supercooled. In contrast, in the majority of XRPCs in P. sieboldii, B. platyphylla, B. pubescens, and red osier dogwood, slow cooling to -80 degrees C produced slight cytorrhysis without clear evidence of intracellular freezing, suggesting that these XRPCs might respond by extracellular freezing. In these XRPCs exhibited putative extracellular freezing; however, deep etching revealed the apparent formation of intracellular ice crystals in restricted local areas. To confirm the occurrence of intracellular freezing, we rewarmed these XRPCs after cooling and observed very large intracellular ice crystals as a result of the recrystallization. Thus, the XRPCs in all the boreal hardwoods that we examined responded by deep supercooling that was accompanied with incomplete desiccation. From these results, it seems possible that limitations to the deep-supercooling ability of XRPCs might be a limiting factor for adaptation of hardwoods to cold climates.  (+info)

The physiological mechanisms controlling plant responses to dynamic changes in ambient solar ultraviolet (UV) radiation are not fully understood: this information is important to further comprehend plant adaptation to their natural habitats. We used the fluorimeter Dualex to estimate in vivo the epidermal flavonoid contents by measuring epidermal UV absorbance (A375) in Betula pendula Roth (silver birch) leaves of different ages under altered UV. Seedlings were grown in a greenhouse for 15 days without UV and transferred outdoors under three UV treatments (UV‐0, UV‐A and UV‐A+B) created by three types of plastic film. After 7 and 13 days, Dualex measurements were taken at adaxial and abaxial epidermis of the first three leaves (L1, L2 and L3) of the seedlings. After 14 days, some of the seedlings were reciprocally swapped amongst the treatments to study the accumulation of epidermal flavonoids in the youngest unfolded leaves (L3) during leaf expansion under changing solar UV environments. ...

An assemblage of tree species with different crown properties creates heterogeneous environments at the canopy level. Changes of functional leaf traits are expected, especially those related to light interception and photosynthesis. Chlorophyll a fluorescence (ChlF) properties in dark-adapted leaves, specific leaf area, leaf nitrogen content (N) and carbon isotope composition (delta C-13) were measured on Picea abies (L.) H. Karst., Pinus sylvestris L. and Betula pendula Roth. in monospecific and mixed boreal forests in Europe, in order to test whether they were affected by stand species richness and composition. Photosynthetic efficiency, assessed by induced emission of leaf ChlF, was positively influenced in B. pendula by species richness, whereas P. abies showed higher photosynthetic efficiency in monospecific stands. Pinus sylvestris had different responses when it coexisted with P. abies or B. pendula. The presence of B. pendula, but not of P. abies, in the forest had a positive effect on ...
To elucidate the mechanisms underlying the population dynamics of Betula ermanii in response to climate change over temporal and spatial dimensions, 310 quadrats were systematically sampled in 7 plots located in the upper treeline region on the north-facing slopes of Changbai Mountains. IKONOS images were used to identify the spatial distribution of Betula ermanii with the aid of a digital elevation model (DEM). Meteorological data were recorded in the field throughout the study area and collected from a nearby long-term weather station, to reconstruct the temperature and precipitation changes. We collected tree-ring samples from a total of 1197 Betula ermanii trees. The correlation coefficients between 14 eco-climate parameters (from 1953 to 2008) and the aggregated annual indices of population dynamics for each quadrat (totaling 310 quadrats) in the corresponding years were calculated via statistical analysis facilitated by GIS technology. The results show that the Betula ermanii population is ...

Bud dynamic in mountain birch, Betula pubescens ssp. czerepanovii, is affected by biotic and abiotic factors such as temperature, light and herbivory. Climate probably has a large impact on module life history strategies i.e. survival, sexual and vegetative reproduction. (Modules are here defined as partially autonomous, repetitive and multicellular subunits within a tree.) Trade-off between present reproduction and future growth and/or reproduction occurs if resources are limiting. There is no direct trade-off between male catkin production and axillary bud production in mountain birch since male catkins are produced at the terminal bud of long-shoot. This bud is aborted when no catkin is present. However, same resources are used for both male catkin production and axillary bud production indicating that trade-offs occur in mountain birch. In my study I have simulated herbivory in order to study what effect trade-offs have on growth of long-shoot and bud performance.

1FM4: Crystal Structure of a Hypoallergenic Isoform of the Major Birch Pollen Allergen Bet v 1 and its Likely Biological Function as a Plant Steroid Carrier
Birch polypore (Piptoporus betulinus) growing on the trunk of a silver birch tree (Betula pendula). This parasitic bracket fungus is found only on birch trees. The visible part of the fungus is the fruiting body that produces the spores, which are held in pores on the underside of the bracket. The fungus uses a fine mycelium network to extract nutrients from the trunk of the tree. It is generally only found on weakened trees, and the fungus can kill a birch tree over time. - Stock Image B250/1623
In a diversity of habitats, from lowland hardwoods, especially in the southern part of the state, to hemlock-white pine-northern hardwoods forest of the north, becoming especially common in the western Upper Peninsula. As is true of the other birches, the pistillate scales and bark of B. alleghaniensis are variable. Very old trees, as in virgin stands in the Upper Peninsula, may have very furrowed or checkered dark bark. Trees in swamps of the southern Lower Peninsula may have dark brown or blackish bark, which peels very little if at all; such trees hardly resemble the widespread typical yellow birch with light yellow-brown, peeling bark, and have sometimes been erroneously referred to B. lenta (which differs in having smaller, nearly or quite glabrous and less densely ciliate scales in the pistillate aments). Betula lenta and B. alleghaniensis both have a characteristic odor and flavor of wintergreen in the crushed bark of young twigs. Betula nigra, river birch, lacks the wintergreen flavor ...
1H4B: Solution Structure, Dynamics, and Hydrodynamics of the Calcium-Bound Cross-Reactive Birch Pollen Allergen Bet V 4 Reveal a Canonical Monomeric Two EF-Hand Assembly with a Regulatory Function
Caloptilia betulicola, the red birch slender, is a moth of the Gracillariidae family. It is found from Scandinavia and the north of European Russia to the Pyrenees and Alps and from Ireland to Poland and Slovakia. In the east it is found up to China, Japan and the Russian Far East. The wingspan is 14-16 millimetres (0.55-0.63 in). There are two generations per year, with adults on wing in June and July and again in September and October. The larvae feed on Betula pendula and Betula pubecens. They mine the leaves of their host plant. The mine starts with an inconspicuous epidermal corridor. Later, a blotch is formed, that quickly develops into a tentiform mine. Generally, the mine is lower-surface, but upper-surface mines are not rare. The frass is deposited in a mass of grains in a corner of the mine. After leaving the mine, the larva moves twice. First it lives in a rolled or folded leaf margin and later in a leaf that is rolled downwards, starting from the leaf tip. Pupation takes place in a ...

Woschnagg, C.; Rak, S.; Venge, P., 1996: Oxygen radical production by blood eosinophils is reduced during birch pollen season in allergic patients
All patients were clinically diagnosed as birch pollen allergic. Seven patients allergic to birch pollen without any gastrointestinal symptoms and seven completely healthy individuals were included in the study for comparison. All patients were examined with a standard skin prick test panel and blood samples were analysed for IgE antibodies by component micro-arrays (ISAC). The two groups of patients underwent gastroscopy and duodenal biopsies were taken both during (May-June) and outside the pollen season (November-January) for each patient. Duodenal biopsies were examined with immunostaining for mast cells (IgE and tryptase), eosinophils (eosinophil peroxidase), T-cells (CD3), and dendritic cells (DC) (CD11c). ...
One example of a diagnostic application of recombinant birch allergens is found in a study examining allergen-specific serum IgE antibodies using the recombinant allergens Bet v 1, Bet v 2 and Bet v 4, as examined in birch-sensitive patients from the province of Cuneo, in northwestern Italy. It was reported that of 372 patients, 215 (58%) had serum IgE antibodies to Bet v 1, 166 (45%) to Bet v 2, and 35 (9%) to Bet v 4. Mono-sensitisation to Bet v 1 occurred in 146 (39%) of patients; in 96 (26%) to Bet v 2; and in only 4 (1%) to Bet v 4. Thirty-nine sera (11%) did not contain allergen-specific IgE antibodies to any of these three individual birch pollen allergens. All 372 sera (100%) had IgE antibodies against natural Birch pollen extract; 162 (44%) contained IgE antibodies reacting with Apple extract (75% of Bet v 1 positive sera). The study concluded that the 3 recombinant birch pollen allergens alone could identify 90% of birch pollen-sensitive patients (7 ...

inproceedings{41c8c41b-a2f5-4475-8be9-0341dfcd092f, abstract = {In northern Sweden, Empetrum hermaphroditum Hagerup dominates the ground layer vegetation in post fire successions by suppressing other plant species. Previous studies suggest that this negative effect by E. hermaphroditum may be explained, at least in part, by the release of phenolic compounds, particularly batatasin-III, from foliage to soil. In this pilot study, we evaluated the effect of batatasin-III on photosynthesis by applying the compound (0.1, 1.0, or 2.8 mM) directly to the transpiration stream of intact Spinacia oleracea L. (spinach) and Betula pendula L. (birch) leaves. Within the concentration range used, batatasin-III had a small, but significant, effect on photosynthesis. The strongest effect was found on CO2 assimilation, but there were also significant effects on respiration and on maximum quantum yield of chlorophyll fluorescence (Fv / Fm). In spinach leaves treated with 2.8 mM of batatasin-III, a 14 % decrease in ...

Virtues: We love Betula nigra for its lustrous deep green foliage and exfoliating bark that peels away from the single or multi-stemmed tree to reveal layers of browns, grays and creams. When developing, the bark is often smooth in a lovely shade of salmon-brown, reddish-brown and/or a cinnamon color. It begins to shed away as it matures, revealing lighter bark of various colors beneath. Common name: river birch; red birch; water birch; black birch. Botanical name: Betula nigra. Flowers: In spring, monoecious flowers (separate male and female flowers on the same plant) begin to bloom with tiny greenish female catkins and drooping, slightly larger brownish male catkins. Brown cone-like fruit develops from the female catkins in late spring/early summer.. Foliage: Leathery, oval-shaped, rich green leaves with double serrated margins fill the arching branches. The foliage transforms into a modest yellow color in fall and quickly drops away, leaving the branches bare for winter.. Habit: These ...

Foods belonging to the order Rosacea -- which includes apple, pear, peach and almond - most commonly cause symptoms in birch-allergic patients. Bet v 1, the major birch tree pollen allergen, accounts for most of the pollens cross-reactivity. (13) In areas where birch pollen is an important aeroallergen, there is an association between spring pollen allergy and allergy to pear and apple. (5, 14, 15, 16) However, studies have shown that although the related major allergens Bet v 1 (from birch pollen) and Mal d 1 (from apple) inhibit to a high degree the binding of IgE to pear Pyr c 1, Api g 1 from celery - also belonging to this family - had little effect, indicating epitope differences between Bet v 1-related food allergens. (3) A number of other factors also influence cross-reactivity between foods and plants containing a Bet v 1-homologous protein. For example, the prevalence of birch-fruit syndrome varies depending on geographic location. The primary sensitisation in birch-fruit syndrome is ...
BACKGROUND: The major birch pollen allergen, Bet v 1, is a member of theubiquitous PR-10 family of plant pathogenesis-related proteins. In recentyears, a number of diverse plant proteins with low sequence similarity toBet v 1 was identified. In addition, determination of the Bet v 1structure revealed the existence of a large superfamily of structurallyrelated proteins. In this study, we aimed to identify and classify all Betv 1-related structures from the Protein Data Bank and all Bet v 1-relatedsequences from the Uniprot database. RESULTS: Structural comparisons ofrepresentative members of already known protein families structurallyrelated to Bet v 1 with all entries of the Protein Data Bank yielded 47structures with non-identical sequences. They were classified into elevenfamilies, five of which were newly identified and not included in theStructural Classification of Proteins database release 1.71. The taxonomicdistribution of these families extracted from the Pfam protein familydatabase ...

Specific IgE from the patients serum reacts with the allergen of interest, which is covalently coupled to an ImmunoCAP. After washing away nonspecific IgE, enzyme-labeled anti-IgE antibody is added to form a complex. After incubation, unbound anti-IgE is washed away and the bound complex is then incubated with a developing agent. After stopping the reaction, the fluorescence of the eluate is measured. Fluorescence is proportional to the amount of specific IgE present in the patients sample (ie, the higher the fluorescence value, the more IgE antibody is present).(Package insert: ImmunoCAP System Specific IgE FEIA, Uppsala, Sweden Rev 02/2005). ...

Rationale: To allow for interdisciplinary research on the relations between socioeconomic conditions and health in the ageing population, a new anonymized longitudinal database - the Linnaeus Database - has been developed at the Centre for Population Studies at Umea University. This paper presents the database and its research potential. Design: Using the Swedish personal numbers the researchers have, in collaboration with Statistics Sweden and the National Board for Health and Welfare, linked individual records from Swedish register data on death causes, hospitalization and various socioeconomic conditions with two databases - Betula and VIP (Vasterbottens Intervention Programme) - previously developed by the researchers at Umea University. Whereas Betula includes rich information about e. g. cognitive functions, VIP contains information about e. g. lifestyle and health indicators. Population and sample size: The Linnaeus Database includes annually updated socioeconomic information from ...

Background: The reason of allergic sensitization to proteins like Bet v 1 is unknown.Results: Bet v 1 binds iron via catechol-based siderophores. It can modulate human immune cells toward Th2 when not carrying iron.Conclusion: Bet v 1 modulates immune cells toward Th2 when being devoid of iron.Significance: We provide the functional basis under which circumstances Bet v 1 becomes an allergen.
Recently, it was also found that UV light selectively induces several primary metabolic activities that are directly or indirectly required for flavonoid formation. This implies complex regulation in the different branches of the phenylpropanoid biosynthesis pathway during UV-B stress. Elevated UV-B radiation significantly increased the concentrations of UV-B-absorbing flavonoids, such as quercetin-3-arabinoside, quercetin-3-glucose + glucuronide and kaempferol- 3-rhamnoside, and a few phenolic acids in silver birch leaves. In Arabidopsis thaliana, the transparent testa-4 (tt4) mutant, which has reduced flavonoids and normal levels of sinapate esters, is more sensitive to UV-B than the wild type when grown under high UV-B irradiance. The tt5 and tt6 mutants, which have reduced levels of UV-absorptive leaf flavonoids and the monocyclic sinapic acid ester phenolic compounds, are highly sensitive to the damaging effects of UV-B radiation. These demonstrated that both flavonoids and other phenolic ...

The nature of the Weekly Letter can be understood in part by interrogating the terms that Birch and Yorke used to describe it. Self-reflexive descriptions of the enterprise-the control information of their communication system-were most common immediately after its inception in the 1740s, where both correspondents used a complex range of terms, both allusive and metaphorical, to describe the letter and its habitual topics of curiosity. Often located in the opening salutations of their letters, Yorkes and Birchs self-reflexive discourse negotiates the conduct of the correspondence, and the complex relationships of patronage and service that the letter instantiates. They both offered repeated commendation of their exchanges, as encouragement and emotional compensation for their literary labour. The letter, Yorke maintained, provided considerable entertainment to him, assuring Birch how agreeable & interesting your Letters are to me; Birch asserted that they gave him so much ...
Wingspan 45-50 mm.. A fairly common moth throughout most of Britain, this species is very similar to Swallow Prominent (P. tremula), but can be identified with care. Compared to that species, gnoma has a more distinct white wedge at the tornus of the forewing, and lacks the wavy white line in the blackish area of the hindwing.. Northern forms can show a chocolate brown head and thorax, in contrast to the typically paler-headed forms further south.. There are two generations, on the wing in May and June, and later in August. The larvae feed on birch (Betula). ...
The tree reached its silvery limbs up towards the night sky like a preacher reaching his hands up to God, but God seemed far away in this place to Jacob. The things celebrating behind him-all around him-looked like devils with their warping faces and gnawing teeth. The offering pots beneath the tree looked old, part of rituals that had gone on forever and a minute. There wasnt a single silver birch on Blake property. They didnt grow too naturally in this part of Indiana, but here one was, glowering over him, waiting for some kind of mistake to reprimand. The forest floor was cleared around the tree with hard packed dirt and the remnants of a thousand footprints, hoof prints, and prints Jacob couldnt recognize. He was alone, but the shadows of the forest weighed over him, waiting for a mistake, waiting for their revelation. But he could do nothing else besides put his offering in the pot. The camp surrounded him. None of the spirits watched him, or seemed to care, but Jacob bet that they could ...

Increasing evidence suggests a role of the immune system in modulation of cognition, but details on affected memory systems are largely lacking. We therefore aimed to study the relation between selected cytokines and subsets of memory, and the impact of age in these relations. From a random population-based sample (the Betula Prospective Cohort Study), 298 women (age 45-90) were studied in terms of episodic recall and recognition, semantic fluency and knowledge, and prospective memory. Circulating cytokines of relevance for cognition and aging were measured with ELISA. Levels of interleukin (IL)-6 and sIL-2R were significantly and negatively associated with most cognitive variables, while the opposite was true for IL-1 beta. Age shared substantial variance with both cytokines and memory, and turned most correlations non-significant when controlled for together with education, BMI and presence of disease. Interactions between age and cytokines were further analyzed in multiple regressions. For ...

This Minor course (optional) gives an overview of Chaos Theory as this is a part of the mathematical discipline of Nonlinaer Dynamical Systems. The discipline is concerned with everything that moves. Think of mathematical descriptions of the motion of mechanical, optical or electronic devices, like the solar system, pendula and swings, LRC networks, etc. Also it is very useful in meteorology, economics, biology, but even in developmental psychology. Sometimes it is appropriate to work with a discrete time set (think of the population dynamics of one day flies). In that case the dynamics is given by iteration of mappings. Also many dynamical systems are governed by ordinary differential equations. In the course we deal with subjects like (un) predictability and with fractal sets, illustrated by examples. We also will discuss historical elements. It is remarkable that a large initiative to Chaos Theory came from the biologist Robert May, the meteorologist Edward Lorenz, the astronomer Michel H non ...

Why is it that cells that are dying from programmed cell death, or apoptosis, do not trigger a strong immune response in the body? After all, dying cells emit a host of proteins that one would normally expect to activate the immune system. Heiko Weyd from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) in Heidelberg already unraveled this biological mystery several years ago: When inducing the process of apoptosis, cells rapidly transport a protein called annexin to their surface. It acts like a stop signal for specific immune cells, thereby preventing the immune system from launching a response. DKFZ researchers Heiko Weyd and Peter Krammer now plan to utilize this highly efficient immune blockade to suppress undesired immune responses, which are the cause, for example, of allergies and potentially life-threatening autoimmune diseases.. The researchers plan is to fuse the effective part of annexin directly to allergens (such as birch pollen) or autoantigens (such as ...

Aim: To test if there is an interactive effect between tree and understory species on the soil microbial community (SMC), community level physiological profiles (CLPP) and soil micro-fauna. Method: A replicate pot experiment with five sapling tree species (Betula pendula, Betula pubescens, Sorbus aucuparia, Quercus petraea and Pinus sylvestris) and a no-tree treatment with and without Calluna vulgaris was established. After 21 months samples were taken for phospholipid fatty acid (PLFA) analysis, CLPP and soil microfauna assessment. Results: There was an interactive effect of tree species and Calluna on the SMC, CLPP and nematode densities. Calluna addition changed the SMC composition (increase in fungal PLFAs) and the CLPP (lower utilisation of most carbon sources but greater utilisation of phenolic acids). A multivariate test for homogeneity of dispersion showed that while Calluna addition resulted in the presence of an altered microbial composition, it did not result in there being less ...

Specific allergy vaccination is an efficient treatment for allergic disease; however, the development of safer vaccines would enable a more general use of the treatment. Determination of molecular structures of allergens and allergen-Ab complexes facilitates epitope mapping and enables a rational approach to the engineering of allergen molecules with reduced IgE binding. In this study, we describe the identification and modification of a human IgE-binding epitope based on the crystal structure of Bet v 1 in complex with the BV16 Fab fragment. The epitope occupies approximately 10% of the molecular surface area of Bet v 1 and is clearly conformational. A synthetic peptide representing a sequential motif in the epitope (11 of 16 residues) did not inhibit the binding of mAb BV16 to Bet v 1, illustrating limitations in the use of peptides for B cell epitope characterization. The single amino acid substitution, Glu(45)-Ser, was introduced in the epitope and completely abolished the binding of mAb ...
The ability of the bark of willow (Salix spp.) to relieve the suffering of pain and fever has been known for at least 2 000 years. The active ingredient in willow bark is salicin, a glucoside that is converted to salicylic acid in the body. Salicylic acid is a component of acetylsalicylic acid, the active ingredient in aspirin, one of the most widely used medicines in the world (see textbox). Today aspirin is produced from synthetic materials [Lust, 1990].[31]. The bark of the North American paper birch (Betula papyrifera) (Figure 6.5) is impervious to water and was used by indigenous tribes in the construction of small, narrow boats known as canoes. Canoes were constructed from large sheets of bark tied together with root fibres of white spruce (Picea glauca) and smeared with the resin of balsam fir (Abies balsamea) [Hora, 1981]. Containers made from the bark of paper birch were also used as containers for collecting sap during the early days of maple sugaring (see Chapter 5).. Figure 6.5 The ...

Climate change is expected to force many species in arctic regions to migrate and track their climatic niche. This requires recruitment from seed, which currently shows very low rates in arctic regions, where long-lived and vegetatively reproducing plants dominate. Therefore, we pose the question whether recruitment (germination and seedling establishment) in arctic regions will significantly improve in a warmer world, and thus allow species to follow their climatic niche. We used a full factorial experiment to examine if realistic warmer temperatures (+3 degrees C; infrared radiation) and increased nitrogen availability (+1.4 g N m(-2) year(-1)) affected germination, seedling survival and above-and below-ground seedling biomass in five species common in subarctic regions (Anthoxanthum odoratum, Betula nana, Pinus sylvestris, Solidago virgaurea, Vaccinium myrtillus). We found that warming increased seedling emergence in all species, but that subsequent mortality also increased, resulting in no ...
