Forests with different flora and vegetation types harbor different assemblages of flower visitors, and plant-pollinator interactions vary among forests. In monsoon-dominated East and Southeast Asia, there is a characteristic gradient in climate along latitude, creating a broad spectrum of forest types with potentially diverse pollinator communities.

Lupane triterpenes were found to promote melanogenesis, a hallmark of B16 2F2 mouse melanoma cell differentiation. Studies of the structure-activity relationships demonstrated that the keto function at C-3 of the lupane skeleton played important roles in the melanogenic activities of lupane triterpenes on melanoma cells. The carbonyl group at C-17 of lupane(More)
OBJECTIVES To clarify the association between glucose intolerance and high altitudes (2900-4800 m) in a hypoxic environment in Tibetan highlanders and to verify the hypothesis that high altitude dwelling increases vulnerability to diabetes mellitus (DM) accelerated by lifestyle change or ageing. DESIGN Cross-sectional epidemiological study on Tibetan(More)
This paper reports a study of paddy vegetation in central Laos. Plants were inventoried and vegetation types classified. Relationships between vegetation and agricultural practices were identified. A total of 184 wild herbaceous species and 17 cultivated species were recorded in two villages. Of the wild species, 19 were used by local people, four were rare(More)
The effects of dietary Yamabushitake mushroom (Hericium erinaceus) on lipid metabolism were examined. C57BL/6J mice were fed a high-fat diet containing hot-water extract (HW-E) and an ethanol extract (EtOH-E) of Yamabushitake mushroom. Administration of HW-E or EtOH-E with a high-fat diet for 28 d resulted in a significant decrease in body weight gain, fat(More)
AIM To reveal the comparison of comprehensive geriatric functions of elderly highlanders in Qinghai Plateau in China among three different ethnic groups. METHODS Activities of daily living (ADL), screening-based depression, quality of life (QOL) and checking-up of metabolic syndrome including community-based oral glucose tolerance test were assessed in(More)
BACKGROUND Although there are several factors which may contribute to oxidative stress at high altitude, little is known about the association between oxidative stress and aging in the community-dwelling elderly in the Tibetan Plateau. METHODS Reactive oxygen species (ROS) and comprehensive geriatric functions were examined among 235 community-dwelling(More)
Wild Edible Herbs in Paddy Fields and Their Sale in a Mixture in Houaphan Province, the Lao People’s Democratic Republic. Multiple wild edible herbs coexist in paddy fields under the agricultural practices used for growing rice. Paddy field vegetation was surveyed and the rural population’s perceptions and use of wild edible herbs were investigated in the(More)
OBJECTIVE Prevalence of hypertension was examined in a widely dispersed (45 110 km(2)) representative group of Ladakhi in Northern India. The influence of hypoxic environment of wide-ranged altitude (2600-4900 m) and lifestyle change on hypertension was studied. METHODS 2800 participants (age 20-94 years) were enrolled. Systolic blood pressure ≥140 mm Hg(More)
