[Ab] Resumo:Phenolic compounds of berries and leaves of thirteen various plant species were extracted with aqueous ethanol and analyzed with UPLC-DAD-ESI-MS, HPLC-DAD, and NMR. The total content of phenolics was consistently higher in leaves than in berries (25-7856 vs. 28-711mg/100g fresh weight). Sea buckthorn leaves were richest in phenolic compounds (7856mg/100g f.w.) with ellagitannins as the dominant compound class. Sea buckthorn berries contained mostly isorhamnetin glycosides, whereas quercetin glycosides were typically abundant in most samples investigated. Anthocyanins formed the dominating group of phenolics in most dark-colored berries but phenolic acid derivatives were equally abundant in saskatoon and chokeberry berries. Caffeoylquinic acids constituted 80% of the total phenolic content (1664mg/100g f.w.) in bilberry leaves. B-type procyanidins and caffeoylquinic acids were the major phenolic compounds in hawthorn and rowanberry, respectively. Use of leaves of some species with prunasin, tyramine and ß-p-arbutin, may be limited in food applications.

[Ab] Resumo:OBJECTIVES: The aim of this study was to investigate the neuroprotective ability of partridgeberry polyphenols in rat primary cortical neurons against oxygen-glucose deprivation/reperfusion (OGD/R) injury in vitro and explore the underlying therapeutic mechanism(s). METHODS: The OGD/R injury was induced in rat primary cortical neurons by incubation with deoxygenated glucose-free medium in a hypoxia chamber. RESULTS: The strongest activity in this regard was exhibited by partridgeberry-derived PPF2 and PPF3, i.e. the flavan-3-ol- and flavonol-rich polyphenol fractions of partridgeberry (P ≤ 0.05). Moreover, partridgeberry polyphenol pre-treatment reduced the membrane damage in primary neurons, as measured by the lactose dehydrogenase (LDH) release assay (P ≤ 0.05). Furthermore, PPF2 and PPF3 pre-treatment (100 µg ml(-1)) for 24 hours, before OGD/R, resulted in the strongest suppression of interleukin (IL)-6 and tumor necrosis factor-α induction by OGD/R injury, compared with the control group (P ≤ 0.05). Additionally, the protein levels of hypoxia-inducible factor (HIF-1α) and PPARγ, quantified by ELISA presented a significant modulation following PPFs treatment (100 µg ml(-1)), favorably toward neuroprotection, compared with the respective controls after OGD/R injury in vitro (P ≤ 0.05). CONCLUSION: In summary, partridgeberry polyphenols at concentrations of 1-100 µg ml(-1), significantly induced a decline in OGD/R injury-triggered apoptosis in vitro, suppressed the inflammatory biomarkers in primary neurons, and modulated the activity of HIF-1α and proliferator-activated receptor gamma (PPARγ) following hypoxic injury.

[Ab] Resumo:OBJECTIVE: To study the effects of lingonberry extraction on mice cognitive impairment caused by chronic stress. METHODS: Kunming mice were randomly divided into six groups, which were control group, stress model group, the fluoxetine group (dose of 4.4 mg · kg(-1) · d(-1)), lingonberry extraction low, medium and high dose group (respectively 50, 100 and 200 mg · kg(-1) · d(-1)). All groups were given chronic uncertainty stress but the control group, and were intragastric administration for 18 days. Then the cognition of the mice was tested by using water maze, the contents of the SOD, GSH-Px, MDA and the activity of the neurotransmitters such as noradreline (NE), serotonin (5-HT), glucocorticoids (GC), acetylcholinesterase (AchE) were measured by using kit. RESULTS: Lingonberry extraction improved the cognition and memory of the mice induced by chronic uncertainty stress, increased the content of the SOD and GSH-Px in mice brain, and decreased the content of oxidative damage markers MDA. Lingonberry extraction could also inhibit the increase of GC, inhibit the activity of AchE in blood serum, elevated the content of 5-HT and NE in mice blood serum and brain. CONCLUSION: Lingonberry extraction improved the cognition and memory of the mice induced by chronic uncertainty stress. The possible mechanism was that lingonberry enhanced the antioxidative ability of tissue and improved the disorder of neurotransmitter levels caused by chronic stress.

[Ti] Título:The Distribution of Cool Spots as Microrefugia in a Mountainous Area.

[Ab] Resumo:It has recently been proposed that microrefugia played an important role in species survival during past climate change events. However, the current distributions of microrefugia remain largely unknown. Wind-hole sites are areas affected by preferential flows of cool air generated in interstitial spaces created by rock fragments or colluvia. Alpine plant species occurring in lowland wind-hole sites isolated from alpine zones may be relicts of the last glacial period. Hokkaido, northern Japan, is known to contain many wind-hole sites in which alpine plant species can occur. Here we surveyed 55 wind-hole sites in the Kitami region, eastern Hokkaido, and observed two alpine plant species (lingonberry, Vaccinium vitis-idaea, and Labrador tea, Rhododendron groenlandicum ssp. diversipilosum var. diversipilosum) in 14 wind-hole sites. Statistical modeling showed that wind-hole sites are likely to occur in areas with high maximum slope angles and volcanic rock cover, and concave surfaces. Our predictions of wind-hole site distributions suggest that such topographic conditions are common in our study area, and that many undiscovered wind-hole sites exist. Ignoring microhabitats may greatly underestimate species distributions in topographically complex regions, and dispersed cool spots may also function as stepping stones and temporal habitats for cold-adapted species. Because these localized unique habitats usually occur in economically unproductive sites, identifying and protecting potential microrefugia (cool spots) would be a robust and cost-effective mitigation of climate change impacts.

[Ab] Resumo:SCOPE: The aim of this work is to identify which proapoptotic pathway is induced in human colon cancer cell lines, in contact with proanthocyanidins extracted from various berries. METHODS AND RESULTS: Proanthocyanidins (Pcys) extracted from 11 berry species are monitored for proapoptotic activities on two related human colon cancer cell lines: SW480-TRAIL-sensitive and SW620-TRAIL-resistant. Apoptosis induction is monitored by cell surface phosphatidylserine (PS) detection. Lowbush blueberry extract triggers the strongest activity. When tested on the human monocytic cell line THP-1, blueberry Pcys are less effective for PS externalisation and DNA fragmentation is absent, highlighting a specificity of apoptosis induction in gut cells. In Pcys-treated gut cell lines, caspase 8 (apoptosis extrinsic pathway) but not caspase 9 (apoptosis intrinsic pathway) is activated after 3 hours through P38 phosphorylation (90 min), emphasizing the potency of lowbush blueberry Pcys to eradicate gut TRAIL-resistant cancer cells. CONCLUSION: We highlight here that berries Pcys, especially lowbush blueberry Pcys, are of putative interest for nutritional chemoprevention of colorectal cancer in view of their apoptosis induction in a human colorectal cancer cell lines.

[Ab] Resumo:Evidence for the efficacy of dietary interventions in protecting against cardiovascular disease has grown significantly, with flavonoids and anthocyanins receiving special attention. Lingonberry (Vaccinium vitis-idaea L.) is a good source of these compounds, and this study examined the protective effects of wild lingonberry found in Manitoba, Canada, against ischemia-reperfusion (IR) injury. Manitoba lingonberry contained 3793 ± 27 mg gallic acid equiv, 120,501 ± 7651 µmol trolox equiv, and 575 ± 20 mg cyanidin-3-glucoside equiv per 100 g dry weight, which correspond with high total phenolic content, antioxidant activity, and anthocyanin content, respectively. A complete methanolic extract and both anthocyanin-rich and phenolic-rich fractions inhibited apoptosis in H9c2 cells during simulated IR. Lingonberry extract and fractions significantly inhibited several markers of apoptosis induced by IR, including nuclei condensation, caspase-3 activation, and MAP kinase signaling. These results provide the first analysis of Manitoba lingonberry and highlight the mechanistic importance of dietary berry compounds for cardiovascular health.

[Ab] Resumo:Dietary polyphenols are abundant antioxidants in the human diet and are associated with lower rates of diabetes and cardiovascular disease. This study aims to determine the effects of cooking white rice (WR) added with lingonberry (WRLB), cranberry (WRCB), and red grape (WRRG) on in vitro digestibility. There was significantly lower level of glucose release for WRRG compared with WR (p < 0.05). WRLB and WRCB showed no effect on glucose release compared with WR (p > 0.05). Increasing concentrations of red grape polyphenol decreased digestibility of white rice (p < 0.05). A positive correlation between the red grape phenolic content and the resistant starch was observed (R = 0.9854). Red grape polyphenol had the greatest impact on reducing in vitro digestibility of white rice. The addition of polyphenols in carbohydrate-rich foods may be a practical means to reduce the high glycemic response of rice eaten around the world.

[Ti] Título:Mammalian herbivores confer resilience of Arctic shrub-dominated ecosystems to changing climate.

[Ab] Resumo:Climate change is resulting in a rapid expansion of shrubs in the Arctic. This expansion has been shown to be reinforced by positive feedbacks, and it could thus set the ecosystem on a trajectory toward an alternate, more productive regime. Herbivores, on the other hand, are known to counteract the effects of simultaneous climate warming on shrub biomass. However, little is known about the impact of herbivores on resilience of these ecosystems, that is, the capacity of a system to absorb disturbance and still remain in the same regime, retaining the same function, structure, and feedbacks. Here, we investigated how herbivores affect resilience of shrub-dominated systems to warming by studying the change of shrub biomass after a cessation of long-term experimental warming in a forest-tundra ecotone. As predicted, warming increased the biomass of shrubs, and in the absence of herbivores, shrub biomass in tundra continued to increase 4 years after cessation of the artificial warming, indicating that positive effects of warming on plant growth may persist even over a subsequent colder period. Herbivores contributed to the resilience of these systems by returning them back to the original low-biomass regime in both forest and tundra habitats. These results support the prediction that higher shrub biomass triggers positive feedbacks on soil processes and microclimate, which enable maintaining the rapid shrub growth even in colder climates. Furthermore, the results show that in our system, herbivores facilitate the resilience of shrub-dominated ecosystems to climate warming.

[Ab] Resumo:In this study, cranberry and lingonberry concentrates were added to commercial sugar-reduced fruit spreads (raspberry-Aloe vera, strawberry-guava, and strawberry-lime), and tested for their antifungal activities. Selected strains of the species Absidia glauca, Penicillium brevicompactum, Saccharomyces cerevisiae and Zygosaccharomyces bailii, as well as xerophilic environmental isolates of the genera Penicillium and Eurotium were used for challenge testing. Initially, varying concentrations of synthetic antifungal agents, such as sodium benzoate, potassium sorbate and butyl 4-hydroxybenzoate were tested against these fungi on wort agar containing 31% fructose at different pH values. Subsequently, the experiments were conducted in fruit spreads containing different concentrations of cranberry and lingonberry concentrates. The results of this study demonstrate that these concentrates were able to inhibit growth of visible colonies of xerophilic and non-xerophilic fungi. Cranberry and lingonberry concentrates are interesting candidates for natural preservation against fungal growth in sugar reduced fruit spreads.

[Ab] Resumo:Arctic-alpine plants have expanded and contracted their ranges in response to the Pleistocene climate oscillations. Today, many arctic-alpine plants have vast distributions in the circumarctic region as well as marginal, isolated occurrences in high mountains at lower latitudes. These marginal populations may represent relict, long-standing populations that have persisted for several cycles of cold and warm climate during the Pleistocene, or recent occurrences that either result from southward step-wise migration during the last glacial period or from recent long-distance dispersal. In light of these hypotheses, we investigated the biogeographic history of the marginal Japanese populations of the widespread arctic-alpine plant Vaccinium vitis-idaea (Ericaceae), which is bird-dispersed, potentially over long distances. We sequenced three nuclear loci and one plastid DNA region in 130 individuals from 65 localities covering its entire geographic range, with a focus on its marginal populations in Japan. We found a homogenous genetic pattern across its enormous range based on the loci analysed, in contrast to the geographically structured variation found in a previous study of amplified fragment length polymorphisms in this species. However, we found several unique haplotypes in the Japanese populations, excluding the possibility that these marginal populations result from recent southward migration. Thus, even though V. vitis-idaea is efficiently dispersed via berries, our study suggests that its isolated populations in Japan have persisted during several cycles of cold and warm climate during the Pleistocene.
