BACKGROUND Traditional medicine has widely been used Betula platyphylla var. japonica to treat various inflammatory diseases including arthritis. OBJECTIVE To determine the anti-inflammatory, anti-nociceptive, and anti-arthritic effects of Betula platyphylla in interleukin-1β (IL-1β)-stimulated

BACKGROUND Obesity causes or aggravates many health problems, both independently and in association with several pathological disorders, including Type II diabetes, hypertension, atherosclerosis, and cancer. Therefore, we screened small compounds isolated from natural products for the development of

Stomata of paper birch (Betula papyrifera Marsh.) seedlings were more open at high humidity than at low humidity and responded rapidly to changes in vapor pressure deficit. SO2 at 0.2 or 0.8 μl l-1 caused partial stomatal closure. Seedlings fumigated with SO2 at 0.2 or 0.5 μl l-1 for 30 h or 0.2 μl

Red pine (Pinus resinosa Ait.) and paper birch (Betula papyrifera Marsh.) seedlings exposed to sulfur dioxide produced acetaldehyde and ethanol, and exhibited increased production of ethylene and ethane. Gas chromatographic measurement of head space gas from incubation tubes containing leaves or

Metal tolerance of a range of birch clones (Betula pendula and Betula pubescens) originating from metal-contaminated sites in England, Wales, Belgium and Finland were tested in soils supplemented with several concentrations of copper (Cu) or zinc (Zn) (500, 2000, 5000 mg kg-1 dry wt. soil of

Seedlings of Norway maple (Acer platanoides), silver birch (Betula pendula), Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) were grown in selected sodium chloride (NaCl) concentrations, soil types and under different watering regimes. Plants were raised from seeds, except for Scots

In September 1984 some sheep in a flock of 250 suffered depression, anorexia, incoordination and difficulty in rising; 50 ewes and weaners died. Post mortem examination revealed petechial bleeding, massive acute liver necrosis and in some animals degeneration of the kidney tubules. The rumen and gut
