彩娱乐app New firmoss species discovered in SW China with potentials to treat Alzheimer
BEIJING, Sept. 10 (Xinhua) -- Researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) under the Chinese Academy of Sciences (CAS) have discovered a new firmoss species in southwest China彩娱乐app, an extract of which has been proved to be effective in the treatment of Alzheimer's disease.
The new species, which is later named Huperzia crassifolia, was discovered during a medical plant inventory research in southwest China's Guizhou Province, according to a CAS press release.
Liu Hongmei, an XTBG associate researcher, a member of the research team said that Huperzia, also commonly known as firmoss, has about 25 species and mainly grows in temperate and boreal climatic zones.
The newly-discovered Huperzia crassifolia is a terrestrial firmoss. It resembles other Huperzia species' gross morphology, but can be easily distinguished by its thicker texture and round-lanceolate pinnae, Liu told Xinhua on Monday.
According to Liu, Huperzine A, a substance found in firmoss plants has been proved to be very effective in the treatment of Alzheimer's disease.
夜尿是指在夜间醒来排尿的现象，对于老年人而言，夜尿的次数和情况常常成为影响生活质量的重要因素。随着年龄的增长，人体的生理机制会发生变化，导致一些老年人在夜间频繁排尿。这一现象不仅影响老人的睡眠质量，还可能暗示潜在的健康问题。那么，彩娱乐app老年人夜尿几次算正常呢？通常认为，如果夜间起夜排尿次数超过一次，就需要关注身体状态了。根据研究，健康的老年人夜间排尿次数在1至2次之间通常被视为正常范围。但不同个体的健康状况可能有所差异，因此在评估夜尿次数时也要考虑其他因素。
The new species is only known to grow in Guizhou, Hubei, Hunan and Chongqing in China, and it often roots in the humus rich soils in broad leaf forests at an altitude from 1,100 to 1,900 meters above sea level with a very small population at each locality, said Liu.
"If people know its medicinal value, Huperzia crassifolia may be in danger of being over-collected. We tentatively propose its conservation status as Endangered (EN) according to the International Union for Conservation of Nature (IUCN) categories and criteria," said Liu.
The findings have been published in the scientific journal PhytoKeys. ■彩娱乐app
