Our purpose in this randomized, double blind, placebo controlled study was to find out the possible effect of a polyphenolic pine bark extract, Pycnogenol® (Pyc) on the level of 8-oxo-7,8-dihydroguanine (8-oxoG) as representative of oxidative damage to DNA and on the DNA repair ability of elderly people. According to our results, three months of Pyc administration had no effect on the level of ...

Stone bark cloth beaters are considered part of the archaeological package that is considered to be associated with the Austronesian expansion from southern China across the Pacific. Here, we present evidence from the Dingmo Site in Bubing basin in Guangxi Zhuang Autonomous Region, China of a bark cloth beater excavated in situ from a stratigraphic layer AMS dated to 7898 ± 34 BP. Based on curr...

bark extract of pinus pinaster contains numerous phenolic compounds such as catechins, taxifolin, and phenolic acids. these compounds have received considerable attentions because of their anti-inflammatory, antimutagenic, anticarcinogenic, antimetastatic and high antioxidant activities. although p. pinaster bark has been intensely investigated in the past; there is comparably less information ...

many hepatoprotective herbal preparations have been recommended in alternative systems of medicine for the treatment of hepatic disorders. no systematic study has been done on protective efficacy of capparis spinosa (capparidaceae) to treat hepatic diseases. protective action of c. spinosa ethanolic root bark extract was evaluated in this study in an animal model of hepatotoxicity, which was in...

Bark and the ambrosia beetles dig into host plants and live most of their lives in concealed tunnels. We assessed beetle community dynamics in tropical dry forest sites in early, intermediate, and late successional stages, evaluating the influence of resource availability and seasonal variations in guild structure. We collected a total of 763 beetles from 23 species, including 14 bark beetle sp...

Methylated fatty acid (FA) compounds in the heartwood and bark of some softwood species, specifically Pinus sylvestris, Abies alba, Picea abies, and Larix decidua, grown in the Czech Republic were evaluated. Strong H2SO4 was used for methylation of the lipids. The highest content of lipid was found in P. abies bark (40.132 mg/g o.d. sample), and the lowest content was in A. alba wood (11.027 mg...

UNLABELLED Pinus sylvestris L. is a very important timber tree in Romania, the bark being the main waste from the wood processing. AIM The aim of this study was to investigate the chemical composition and antitumor effects against HeLa cells of a polyphenol-rich extract from Pinus sylvestris L. bark. MATERIAL AND METHODS The polyphenolic content and profile were analyzed by means of spectro...

This thesis examines the possibility to use computerized image analysis for quality control of wood-chips used for pulping. The quality control in this case means controlling the amount of bark in the chips, since bark can create damages in the finished product. At present the chips quality at Stora Enso Packaging Boards, Skoghall Mill is controlled with samples where the amount of bark is eval...
