In the presence of the nonselective herbicide glyphosate (N-[phosphonomethyl]glycine), buckwheat (Fagopyrum esculentum Moench) hypocotyls and cultured cells of Galium mollugo L. accumulate an organic acid, which was identified as shikimate by mass-spectroscopy of its methyl ester. After growth in 0.5 millimolar glyphosate for 10 days, G. mollugo cells contained shikimate in amounts of up to 10%...

Within-stand variation in understory species composition and biomass was studied in 16 even-aged stands of mixed Red Alder Sitka Spruce Western Hemlock (Alnus rubra Picea sitchensis Tsuga heterophylla) forest. The sites were upland sites, and the stands were 28-39 years old. We compared understory within three categories of microsite types: Red Alder-dominated, conifer-dominated, and mixed alde...

Classical Mendelian experiments were conducted to determine the genetics and inheritance of quinclorac and acetolactate synthase (ALS)-inhibitor resistance in a biotype of Galium spurium. Plants were screened with the formulated product of either quinclorac or the ALS-inhibitor, thifensulfuron, at the field dose of 125 or 6 g active ingredient (a.i.) ha respectively. Segregation in the F2 gener...

This research was conducted on selected underutilized plant species in Ayubia National Park, Pakistan. The six most prominently used medicinal and food species viz., Adhatoda vasica, Artemisia scoparia, Galium aparine, Amaranthus viridis, Hedera nepalensis and Urtica dioica that gain little attention by scientific research and local community were selected as underutilized species. Due to their...

BACKGROUND Although asthma symptoms can be temporarily controlled, it is recommended to use effective low-risk, non-drug strategies to constitute a significant advance in asthma management. Acupuncture has been traditionally used to treat asthma; however, the evidence for the efficacy of this treatment is still lacking. Previous clinical trials of acupuncture in treating asthma were limited by ...

BACKGROUND Dry eye is usually managed by conventional medical interventions such as artificial tears, anti-inflammatory drugs and surgical treatment. However, since dry eye is one of the most frequent ophthalmologic disorders, safer and more effective methods for its treatment are necessary, especially for vulnerable patients. Acupuncture has been widely used to treat patients with dry eye. Our...

BACKGROUND De qi is a sensory response elicited by acupuncture stimulation. According to traditional Chinese medicine (TCM), de qi is essential for clinical efficacy. However, the understanding of the neurobiological basis of de qi is still limited. OBJECTIVE To investigate the relationship between brain activation and de qi by taking a single-photon emission computed tomography (SPECT) scan ...
