聚羟基脂肪酸酯(polyhydroxyalkanoates,PHA)是微生物在碳源充足、氮源或者磷缺乏的条件下形成的细胞内聚酯.根据PHA单体碳原子数的不同,其可被划分为三大类:短链PHA (PHASCL)、中长链PHA (PHAMCL)以及长链PHA (PHALOL).门多萨假单胞菌(Pseudomonas mendocina) NK-01是本实验室分离,天然的产PHAMCL的菌株,能利用葡萄糖
The use of medicinal plant cells has broad application prospects on production of secondary metabolites through the means of suspension culture as microorganism fermentation.However,compared with many
本研究依托黑龙江省农科院34年长期定位试验,选取三组不同施氮量处理:无氮肥组(CK和PK)、施一倍氮肥组(N1,NP,NPK和NK)和施二倍氮肥组(N2)耕层土壤为研究对象,借助454平台进行高通量测序和Real-time PCR技术,以氨氧化古菌amoA基因为分子标靶,解析不同施氮量对黑土中氨氧化古菌的影响.结果表明,随着氮肥施用量的增加,黑土中AOA amoA拷贝数由2.61×107/g土壤显
Oxidative stress is actively involved in dopaminergic neuronal degeneration in Parkinsons disease (PD).Our previous studies have identified that 100 Hz electro-acupuncture (EA) stimulation at ZUSANLI
Extensive research has shown that the aggregation and toxicity of amyloid -beta protein (A β) are closely related to the cognitive deficits in Alzheimers disease (AD).Inhibition of mammalian target of
Neuropeptide W (NPW) is a recently identified neuropeptide that binds to G-protein-coupled receptors GPR7 and GPR8,which are highly expressed in several discrete regions of the rodent brain including
The orexin,a neuropeptide also called hypocretin,is produced exclusively by a specific group of neurons whose cell bodies are located in the lateral hypothalamic/perifornical area.Consistent with the
Background:Microglial activation contributes to neuroinflammation and neuronal damages in neurodegenerative disorders including Alzheimers and Parkinsons diseases.It has been suggested that neurodegen
Hydrogen sulfide (H2S),along with NO and CO,considered to be the third endogenous gaseous neuromodulator,also serves as an important neuroprotective agent.However,little is known about the relationshi
Dnmt1 and Dnmt3a are two main DNA Methyltransferases.Recently a lot of reseach indicate that the methylation mediated by Dnmt1 and Dnmt3a plays an important role in the functions of adult nervoussyste
