Jennifer L Chandler
Understory light environments change rapidly following timber harvest, and while many understory species utilize and benefit from the additional light, this response is not ubiquitous in shade-obligate species. I examined the effects of patch cut timber harvest on the physiology and growth of an obligate forest understory species to determine if disturbances via timber harvest are physiological stressors or whether such disturbances provide physiological benefits and growth increases in understory species. Forest canopy structure, along with photosynthesis, respiration, water use efficiency, stomatal conductance, and growth rates of American ginseng were quantified one summer before and two summers after patch cut timber harvest...

Fermented black ginseng (FBG) is processed by the repeated steaming and drying of fresh ginseng followed by fermentation with Saccharomyces cerevisiae. It is known to possess anti‑oxidative effects. Skin wrinkle formation is associated with oxidative stress and inflammatory reactions. The aim of this study was to determine whether FBG possesses anti‑wrinkle activity using human fibroblasts (HS68). According to the Korea Ministry of Food and Drug Safety (MFDS) guidelines for the evaluation of the efficacy of functional anti‑wrinkle cosmetics, we attempted to elucidate the effects of FBG on type I procollagen, matrix metalloproteinase (MMP)‑1, MMP‑2, MMP‑9 and tissue inhibitor of metalloproteinase‑2 (TIMP‑2)...

Bacterial endotoxin lipopolysaccharide (LPS) can induce systemic inflammation, and therefore disrupt learning and memory processes. Ginsenoside Rg1, a major bioactive component of ginseng, is shown to greatly improve cognitive function. The present study was designed to further investigate whether administration of ginsenoside Rg1 can ameliorate LPS-induced cognitive impairment in the Y-maze and Morris water maze (MWM) task, and to explore the underlying mechanisms. Results showed that exposure to LPS (500 μg/kg) significantly impaired working and spatial memory and that repeated treatment with ginsenoside Rg1 (200 mg/kg/day, for 30 days) could effectively alleviate the LPS-induced cognitive decline as indicated by increased working and spatial memory in the Y-maze and MWM tests...

Ginsenoside is a large family of triterpenoid saponins from panax ginseng, which possesses various important biological functions. Due to the very similar structures of these complex glycoconjugates, it is crucial to develop powerful analytic method to identify ginsenosides qualitatively or quantitatively. We herein report an eight-channel fluorescent sensor array as artificial tongue to achieve the discriminative sensing of ginsenosides. The fluorescent cross-responsive array was constructed by four boronlectins bearing flexible boronic acid moieties (FBAs) with multiple reactive sites and two linear poly(phenylene-ethynylene) (PPEs)...

Angiogenesis is a regulated process integral to many physiological and pathological situations, including carcinogenesis and tumor growth. The majority of the angiogenic processes are related to inflammation. The interplay is not only important in the case of pathogen entry but also influential in chronic inflammatory diseases, tumor growth and tissue regeneration. Modulating the interaction between inflammation and angiogenesis could be an important target for cancer treatment and wound healing alike. Ginseng has a wide range of pharmacological effects, including anti-inflammatory and angiogenesis-modulating activities...

The traditional Japanese herbal medicine hangeshashinto (HST) has beneficial effects for the treatment of oral ulcerative mucositis (OUM) in cancer patients. However, the ingredient-based mechanism that underlies its pain-relieving activity remains unknown. In the present study, to clarify the analgesic mechanism of HST on OUM-induced pain, we investigated putative HST ingredients showing antagonistic effects on Na(+) channels in vitro and in vivo. A screen of 21 major ingredients using automated patch-clamp recordings in channel-expressing cells showed that [6]-gingerol and [6]-shogaol, two components of a Processed Ginger extract, considerably inhibited voltage-activated Na(+) currents...

Siberian ginseng (Eleutherococcus senticosus) is a woody medical shrub belonging to the Araliaceae family. E. senticosus contains various types of saponins, including oleanane, noroleanane, lupane, and 3,4-secolupane types, depending on the aglycone structure. Oleanane-type triterpenes are the major saponin components in E. senticosus. Two enzymes (β-amyrin synthase and β-amyrin 28-oxidase) are essential for oleanane-type saponin biosynthesis from 2,3-oxidosqualene. In the present study, two full-length cDNAs encoding EsBAS and CYP716A244 were isolated based on transcriptomics analysis of plant leaves...
