Asthma is a common chronic inflammatory disease in which lung airways narrow and produce extra mucus. Numerous medications, such as steroids, are used to prevent or control asthmatic symptoms, but side effects are associated with those medications. There are reports of anti-inflammatory,
Seven-month-old Scots pine seedlings were inoculated with water or culture filtrate (controls), with 10,000, or 20,000 (experiment 1), and with 2,500 (experiment 2) Bursaphelenchus xylophilus B.C. isolate nematodes and maintained under defined experimental conditions. Controls did not develop pine
Pinus halepensis Mill. is a pine native to the Mediterranean region that is generally located from sea level up to an altitude of 200 meters. In July 2012, extensive leaf yellowing and scorching were observed on the foliage of two specimens of P. halepensis in a public park of Alassio municipality,
Magnesium (Mg) nutrition and photosynthesis were studied in clones of Pinus radiata D. Don grown in sand culture for 21 weeks at four Mg concentrations (0.008, 0.04, 0.2 and 0.4 mM) and three potassium (K) concentrations (0.25, 0.5 and 2.5 mM). We found significant clonal variation in Mg nutrition
The pathogen Mycosphaerella dearnessii Barr. (syn. Scirrhia acicola; anamorph Lecanosticta acicola), the causal agent of brown spot needle blight, was observed on Pinus mugo in the Botanical Garden in Gardone (Brescia), on the western side of Garda Lake in northeastern Italy. Symptoms were first
The saprotrophic fungus Phlebiopsis gigantea has been used for several years as a biocontrol agent against the conifer pathogen Heterobasidion annosum. Although the effectiveness of P. gigantea in biocontrol has been shown empirically, the long-term effect on living conifer trees as well as the
In the fall of 2009, damping-off of Pinus radiata seedlings was observed in a pine nursery in Sant Feliu de Buixalleu, Girona Province, northeastern Spain. Plants exhibited needle blight, extensive root necrosis, and root death. Root sections of symptomatic plants were cut, washed under running tap
Hot water extract of pine cone (PCE) of Pinus parviflora Sieb. et Zucc. dose-dependently suppressed both solid and ascites tumor cells transplanted into various mice. Acidic polysaccharides of PCE significantly increased the survival time of mice bearing ascites tumor cells, and activity increased
In this study, we compared the anti-inflammatory activity of Pinus koraiensis cone bark extracts prepared by conventional extraction and microwave-assisted extraction (MAE). Water extracts and 50% ethanol extracts prepared using MAE were applied to RAW 264.7 cell at 5, 10, 25, and 50 μg/mL of
Inflammation and oxidative stress are related to cancer initiation and progression. We hypothesized that dietary supplementation with a procyanidin-rich Pinus pinaster extract (Pyc) with known antioxidant and anti-inflammatory effects could induce systemic protection, thereby attenuating tumor
Plant tissue necrosis and subsequent cell death are usually observed during in vitro regeneration in conifers, especially in plant regeneration via somatic organogenesis in pine species. Cell death is correlated with the elevated levels of peroxides. In this investigation, the effects of
Excess accumulation of lipids and oxidative stress in the liver contribute to nonalcoholic fatty liver disease (NAFLD). We hypothesized that Pinus densiflora Sieb. et Zucc. (PSZ) can protect against NAFLD by regulating lipid accumulation and oxidative stress in the liver. To investigate the effect
Acid rain (AR), a serious environmental issue, severely affects plant growth and development. As the gymnosperms of conifer woody plants, Pinus massoniana (AR-sensitive) and Taxus wallichiana var. mairei (AR-resistant) are widely distributed in southern China. Under AR stress, significant necrosis
Seedlings of Pinus ponderosa (ponderosa pine) and Abies concolor (white fir) were exposed to acidic fog (pH 2.0, 3.0 or 4.0) in open-field plots for six weeks. The two species exhibited dissimilar injury responses; neither current year nor previous year needles of ponderosa pine were injured by pH
Chamaecyparis obtusa (C. obtusa) and Pinus densiflora (P. densiflora) have been traditionally used as antibiotic, antinociceptive and anti-inflammatory agents in Asian folk medicine. Recent studies have demonstrated antioxidant, antiproliferative and anti-inflammatory effects of C. obtusa and P.
