Amplified fragment length polymorphism (AFLP) is a powerful fingerprinting technique that is widely applied in ecological and population genetic studies. However, its routine use has been limited by high costs associated with the optimization of fluorescently labelled markers, especially for individual study systems. Here we develop a low-cost AFLP protocol that can be easily transferred betwee...

OBJECTIVE To observe the effect of salvia miltiorrhizae injection on inflammatory mediator levels and mesenteric lymph nodes in severe acute pancreatitis (SAP) and obstructive jaundice (OJ) rats and explore the protective mechanism of salvia miltiorrhizae on the lymph nodes of these rats. METHODS A total of 288 rats were used in SAP-associated and OJ-associated experiments. The rats were rand...

PURPOSE we aim to explore the protective effects of Salvia miltiorrhizae injection on multiple organs of obstructive jaundice (OJ) rats through observing the impact of this injection on the pathological alterations in these organs and the contents of endotoxin, PLA(2), and TNF-alpha in the blood. METHODS A total of 90 mice were randomly divided into sham-operated group, model-control group, a...

essential oils are volatile, natural, complex compounds formed by aromatic plants as secondary metabolites. in nature, essential oils play an important role in protecting plants in form of antibacterials, antivirals, antifungals, insecticides properties and also against herbivores. they also may attract some insects to use them in dispersion of pollens and seeds, or repel undesirable others. pr...

Global cloud/cloud system-resolving models are perceived to perform well in the prediction of the Madden-Julian Oscillation (MJO), a huge eastward -propagating atmospheric pulse that dominates intraseasonal variation of the tropics and affects the entire globe. However, owing to model complexity, detailed analysis is limited by computational power. Here we carry out a simulation series using a ...

A Madden-Julian Oscillation (MJO) is a massive weather event consisting of deep convection coupled with atmospheric circulation, moving slowly eastward over the Indian and Pacific Oceans. Despite its enormous influence on many weather and climate systems worldwide, it has proven very difficult to simulate an MJO because of assumptions about cumulus clouds in global meteorological models. Using ...

The processes that lead to changes in the propagation and maintenance of the Madden-Julian Oscillation (MJO) as a response to increasing CO2 are examined by analyzing moist static energy budget of the MJO in a series of NASA GISS model simulations. It is found changes in MJO propagation is dominated by several key processes. Horizontal moisture advection, a key process for MJO propagation, is f...

Detecting chaos and estimating the limit of prediction time in heavy-noise environments is an important and challenging task in many areas of science and engineering. An important first step toward this goal is to reduce noise in the signals. Two major types of methods for reducing noise in chaotic signals are chaos-based approaches and wavelet shrinkage. When noise is strong, chaos-based appro...

Enhanced Expression of Genes Involved in the Biosynthesis Pathway Tanshinones Tetraploid Plants Salvia Officinalis L.

In petals of Salvia high concentrations of ether cause an increase in oxygen consumption and in the production of CO(2), while at the same time a decrease occurs in the acidity of the cell contents.
