一测多评法测定花椒及相关产品中4个酰胺类物质的含量Simultaneous determination of four amides in Zanthoxylum bungeanum Maxim. and its related products with quantitative analysis of multi-components by single marker

open access: yesZhongguo youzhi
为了对花椒及相关产品中酰胺类化合物准确定量,以羟基-α-山椒素为内参物,建立了一测多评法同时测定花椒及相关产品中羟基-α-山椒素、羟基-β-山椒素、羟基-γ-山椒素和羟基-ε-山椒素4个成分含量的方法。采用高效液相色谱法(外标法)建立了4个成分的标准曲线,并对外标法进行了方法学考察。在外标法的基础上,以羟基-α-山椒素为内参物,获得其他3个成分的相对校正因子和相对保留时间,以相对保留时间对样品峰进行定性,以相对校正因子和外标法获得的样品中羟基-α-山椒素含量计算花椒及相关产品中其他3个成分的含量 ...

A novel, PCP‐dependent tissue organising principle coordinating morphogenesis between embryonic skin epidermal layers

open access: yesJournal of Anatomy, EarlyView.
‘Outside‐in’ expression of Fz6 across multiple layers of mouse embryo epidermis is connected to Fz6 asymmetry in the basal layer plane. Fz6 loss‐of‐function correlated with failure to: coordinate axial bias of cell long axis orientation across epidermal layers, switch axial cell long axis orientation during suprabasal layer development and establish ...

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

open access: yesMedical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Metabolomic and Single‐Cell Transcriptomic Analyses Shed Light on Secondary Metabolite Profiling and Potential Developmental Dynamics of Glandular Trichomes in Artemisia argyi

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant glandular trichomes (GTs) are characterised by their ability to synthesise and store abundant secondary metabolites of significant biological importance. The medicinal plant Artemisia argyi exhibits a dense covering of GTs, yet the precise metabolic compositions and the developmental molecular dynamics of A.

Molecular study of lipids in humic acids by sequential chemical degradation [PDF]

open access: yes, 2009
Lipidy v půdě vykazují poměrně vysokou resistenci k biodegradaci, mohou proto tak zajistit informace o zdrojích organické hmoty a diagenetických procesech. Půdní organická hmota je vysoce heterogenní a vyskytují se v ní různé dynamické systémy.
