Sulfur fumigation can induce chemical transformation of bioactive components, consequently the alteration of bioactivities or even toxicities of medicinal herbs. Inspecting Chinese patent medicines (CPM) contained sulfur-fumigated constituent herbs is crucial for ensuring the safety and efficacy of CPM. Paeonifiorin sulfonate is a sulfur-fumigation induced compound of Moutan Cortex (MC), one of the main constituent herbs of a commonly used CPM Liu-Wei-Di-Huang-Wan (LWDHW). Herein, we investigated the approach of paeonifiorin sulfonate as a characteristic marker for specifically inspecting LWDHW potentially contained sulfur-fumigated MC (SFMC)...

Rosin, a cinnamyl alcohol glucoside, is one of the important ingredients in Rhodiola rosea, which is a valuable medicinal herb used for centuries. Rosin displayed multiple biological activities. The traditional method for producing rosin and derivatives is direct extraction from R. rosea, which suffers from limited availability of natural resources and complicated purification procedure. In this work, we achieved de novo biosynthesis of rosin in Escherichia coli. Firstly, a biosynthetic pathway of aglycon cinnamyl alcohol from phenylalanine was constructed...

Personalized healthcare systems support the provision of timely and appropriate information regarding healthcare options and treatment alternatives. Especially for patients that receive multi-drug treatments a key issue is the minimization of the risk of adverse effects due to drug-drug interactions (DDIs). DDIs may be the result of doctor prescribed drugs but also due to self-medication of conventional drugs, alternative medicines, food habits, alcohol or smoking. It is therefore crucial for personalized health systems, apart from assisting physicians for optimal prescription practices, to also provide appropriate information for individual users for drug-drug interactions or similar information regarding risks for modulation of the ensuing treatment...

The desire for local, fresh produce year round is driving the growth of hydroponic growing systems in the United States. Many food crops, such as leafy greens and culinary herbs, grown within hydroponics systems have their root systems submerged in recirculating nutrient-dense fertilizer solutions from planting through harvest. If a foodborne pathogen were introduced into this water system, the risk of contamination to the entire crop would be high. Hence, this study was designed to determine whether Escherichia coli O157:H7, non-O157 Shiga toxin-producing E...

An airborne laser plasma is suggested as an ambient ion source for mass spectrometry. Its fundamental physical properties, such as an excellent spatial and temporal definition, high electron and ion densities and a high effective cross section in maintaining the plasma, make it a promising candidate for future applications. For deeper insights into the plasma properties, the optical plasma emission is examined and compared to mass spectra. The results show a seemingly contradictory behavior, since the emitted light reports the plasma to almost entirely consist of hot elemental ions, while the corresponding mass spectra exhibit the formation of intact molecular species...
