The production of artemisinin precursors in tobacco [PDF]

Plant Biotechnology Journal, 2010
SummaryArtemisinin, in the form of artemisinin‐based combination therapies (ACTs), is currently the most important compound in the treatment of malaria. The current commercial source of artemisinin is Artemisia annua, but this represents a relatively expensive source for supplying the developing world.

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy

Advanced Healthcare Materials, EarlyView.
Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

Portable Molecularly Imprinted Polymer Sensor for Rapid Swab‐Based Detection of Norovirus

Advanced Healthcare Materials, EarlyView.
This work reports a rapid, portable smartphone‐based sensor capable of detecting four norovirus genotypes from swab samples within 15 min. Sensor selectivity was validated through evaluation against four common live viruses. The swab‐based sampling process enabled simple sample preparation combined with the compact detection system, supporting use of ...

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

Advanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Identification characteristics of non-smoking tobacco products

Новые технологии, 2021
Modern trends in the reduction of cigarette consumption have led to the spread of smokeless tobacco and non-tobacco nicotine-containing products [1]; their variety creates certain problems with the identification of products in this segment.

Fuels in tobacco production

Poljoprivreda, 2008
Energy production from biomass can reduce „ greenhouse effect” and contribute to solving energy security especially in the agricultural households which rely on energy from fossil fuels. In Croatia flue-cured tobacco is produced on about 5000 ha. Gross income for the whole production is about 180 000 000 kn/year.
