Antioxidant and Neuroprotective Effects of Seed Oils from and in : A Comparative Analysis and Mechanism Study.

Excess reactive oxygen species (ROS) can accelerate amyloid β (Aβ) aggregation and tau protein hyperphosphorylation in neuron cells, which further leads to neurodegenerative diseases such as Alzheimer's disease (AD). Therefore, there is an urgent need to find natural and safe antioxidants for preventing or treating such neurodegenerative diseases. The seeds of Maxim and Hayata have long been used for medicinal and edible purposes in China.

Effect of Different Edible Germplasm on Its Seed Oil to Enhance Antioxidant and Anti-Aging Activity in .

The seeds of various L. plants have been frequently used as snacks instead of for traditional medicinal purposes in China. However, there is still a need to identify the species based on seeds from germplasm for the potential biological activities of their seed oil.

Cloning, Heterologous Expression, and Characterization of a Neutral Uricase from sp. CSAJ-16 in Cangshan Mountain.

Uricase (or Urate oxidase), a key enzyme involved in purine metabolism, is commonly used in treating conditions such as gout, hyperuricemia, and tumor lysis syndrome. In this study, a uricase-producing strain (named CSAJ-16) was isolated from the soil sample of Cangshan Mountain, Yunnan Province, China. This strain was identified as sp.

The phylogeny and divergence time of Ophiocordyceps sinensis and its host insects based on elongation factor 1 alpha.

Ophiocordyceps sinensis Berk. is a fungal parasite that parasitizes the larvae of Hepialidae and is endemic to the Qinghai-Tibet Plateau (QTP). The phylogeny and divergence time of O.

Haplotype Diversity of NADPH-Cytochrome P450 Reductase Gene of and the Effect on Fungal Infection in Host Insects.

Berk. is a fungal parasite that parasitizes the larvae of Hepialidae and is used as a traditional Chinese medicine. However, it is not clear how infects its host.

Effects of fungus-host associations on nucleoside differences among Ophiocordyceps sinensis populations on the Qinghai-Tibet Plateau of China.

Nucleosides are active components in Ophiocordyceps sinensis. All individual nucleoside contents in both fruiting and caterpillar bodies were significantly different among the 24 O. sinensis populations that are distributed across the Qinghai-Tibet Plateau of China.

Assessment of the Genetic Diversity of Different Job's Tears (Coix lacryma-jobi L.) Accessions and the Active Composition and Anticancer Effect of Its Seed Oil.

Job's tears (Coix lachryma-jobi L.) is an important crop used as food and herbal medicine in Asian countries. A drug made of Job's tears seed oil has been clinically applied to treat multiple cancers.

A comparative study of with related species: Morphological characteristics, ITS sequences and active compounds.

Morphological characteristics, ITS sequences, and active compounds have been used to differentiate between species of used in the traditional Chinese medicines Flos Lonicerae Japonicae (FLJ) and Flos Lonicerae (FL). FLJ includes whereas FJ includes , , and . FLJ could be distinguished from FL using four quantitative and 10 qualitative characters, ITS sequences, chlorogenic acid and luteoloside contents.

Genetic diversity and distribution patterns of host insects of Caterpillar Fungus Ophiocordyceps sinensis in the Qinghai-Tibet Plateau.

The caterpillar fungus Ophiocordyceps sinensis is one of the most valuable medicinal fungi in the world, and it requires host insects in family Hepialidae (Lepidoptera) to complete its life cycle. However, the genetic diversity and phylogeographic structures of the host insects remain to be explored. We analyzed the genetic diversity and temporal and spatial distribution patterns of genetic variation of the host insects throughout the O.

Comparative phylogenetic relationships and genetic structure of the caterpillar fungus Ophiocordyceps sinensis and its host insects inferred from multiple gene sequences.

Ophiocordyceps sinensis (Ascomycota: Ophiocordycipitaceae) is a native fungal parasite of Hepialidae caterpillars and one of the most economically important medicinal caterpillar fungi in China. However, little is known about the phylogenetic and evolutionary relationships between O. sinensis and its host insects.

[Identification of four medicines of Panax L. revealed by mitochondrial nad 1 gene b/c intron].

Objective: To study the identification method and phylogenetic relationships of four medicines of Panax L genus: Panax ginseng C. A. Meyer, P.

Metabolism of reactive oxygen species in cotton cytoplasmic male sterility and its restoration.

To elucidate reactive oxygen species (ROS) metabolism of cotton cytoplasmic male sterility and the effects of restorer gene on the metabolism of ROS, the metabolism changes in the production and scavenging of ROS and gene expression related to ROS-scavenging enzymes were investigated in the anther mitochondria of CMS line, maintainer line and hybrid F(1). During the abortion preliminary stage (sporogenous cell division stage), anthers of CMS line had a little higher superoxide (O(2)(-)) production rate and hydrogen peroxide (H(2)O(2)) and malondialdehyde (MDA) contents than those of maintainer or hybrid F(1. )Simultaneously, a little higher ROS contents might serve as a signal to increase the activity of superoxide dismutase (SOD) in anthers of CMS line to reduce the ROS damage to the anther development.

[Tissue culture and rapid propagation of Trichosanthes kirilowii].

Objective: To study tissue culture of Trichosanthes kirilowii, and establish the technique of rapid propagation.

Methods: Cluster buds were induced from stem tip and stem with axillary bud, calluses were induced from stems and leaves.

Results: Cluster buds could be induced on both the bud and axillary bud from 2-years-old tuber of Trichosanthes kirilowii with MS medium containing 2 mg/L BA and 0.
