Enrichment and health risks associated with trace elements in medicine food homology teas
This study aims to determine the total and infused concentrations of nine trace elements (Fe, Mn, Zn, Cd, Cr, Cu, As, Pb, and Ni) in 12 MFHTs collected from 18 provinces in China, to evaluate their potential risks to human health, and to explore the factors affecting the trace element enrichment in traditional MFHTs. The exceedances of Cr (82%) and Ni (100%) in 12 MFHTs were higher than those of Cu (32%), Cd (23%), Pb (12%), and As (10%). The high values of the Nemerow integrated pollution index of dandelions and Flos sophorae (25.96 and 9.06, respectively) indicate severe trace metal pollution. The health risk assessment ...

Molecules, Vol. 28, Pages 2316: Controllable Preparation of Gold Nanocrystals with Different Porous Structures for SERS Sensing
ixuan Yao Porous Au nanocrystals (Au NCs) have been widely used in catalysis, sensing, and biomedicine due to their excellent localized surface plasma resonance effect and a large number of active sites exposed by three-dimensional internal channels. Here, we developed a ligand-induced one-step method for the controllable preparation of mesoporous, microporous, and hierarchical porous Au NCs with internal 3D connecting channels. At 25 &deg;C, using glutathione (GTH) as both a ligand and reducing agent combined with the Au precursor to form GTH&ndash;Au(I), and under the action of the reducing agent asco...

Dandelion-like covalent organic frameworks with high-efficiency fluorescence for ratiometric sensing and visual tracking-by-detection of Fe < sup > 3 < /sup >
Anal Chim Acta. 2023 Jan 25;1239:340671. doi: 10.1016/j.aca.2022.340671. Epub 2022 Nov 24.ABSTRACTIron ions, one of the most common heavy metal pollutants in industrial waste materials, are continuously actively or passively delivered to the environment. Meanwhile, the importance of Fe3+ in biological processes in vivo can not be neglected due to its crucial role in maintaining normal physiological function. Therefore, a ratiometric fluorescence covalent organic framework (TD-COF) was constructed for tracking-by-detection of Fe3+. Alkynes-extended 1,3,6,8-tetrakis(4-ethynyl benzaldehyde)-pyrene (TEBPY) with complete planar...

Dandelion
Don Freeman ’s 1964 book, Dandelion, may not be as well-known as his Corduroy series, but it certainly withstands the test of time. I read it as a child with my own mother and then enjoyed it with my children over 30 years later! The book on my shelf is slightly worse for wear due to age and handling, but its coloring has always been soothingly neutral. The golden hue of Dandelion’s fur (he’s a lion, if you didn't know) plays across different aspects of the charcoal grey sketches, and the story is as straightforward as the illustrations.

Mechanistic Role of Methanolic Extract of Taraxacum officinale Roots as Cardioprotective Against Ischemia-Reperfusion Injury-Induced Myocardial Infarction in Rats
This study not only explored the overall cardioprotective potential but also tried to explore its molecular mechanism using pharmacological inhibition via L-NAME and glibenclamide. Pretreatment of methanolic extract of Taraxacum officinale significantly attenuated (p < 0.001) increased levels of lactate dehydrogenase (LDH), creatine kinase (CK), infarct size, and thiobarbituric acid reactive substance (TBARS), while it increased the reduced levels of protein content, glutathione (GSH), and catalase (CAT) activity. Results showed that pretreatment with methanolic extract of Taraxacum officinale provides cardioprotection ...

Taraxasterol inhibits inflammation in osteoarthritis rat model by regulating miRNAs and NF- κB signaling pathway
This study aimed to clarify the function of taraxasterol (TAX) isolated from Taraxacum officinale in the papain-induced rat OA model. We observed that TAX alleviated the typical OA-caused phenomena in the joint. The expression of serum inflammatory mediators such as TNF-α, IL-6, and IL-1β was also repressed by TAX. In addition, NF-κB signaling pathway was repressed by TAX. Furthermore, two microRNAs: miR-140 and miR-146a were elevated after TAX treatment in OA rat model. Interestingly, several common targets of miR-140 and miR-146a, including HSPA4L, ST5, and ERBB4, were confirmed to be regulated by TAX. Inflammatory re...

Viruses, Vol. 14, Pages 2511: Weed Hosts Represent an Important Reservoir of Turnip Yellows Virus and a Possible Source of Virus Introduction into Oilseed Rape Crop
umar Kundu Turnip yellows virus (TuYV) is one of the most important pathogens of oilseed rape worldwide. The virus has a large host range including many crop species (e.g., oilseed rape, pea, chickpea) and weeds from more than twenty plant families. Other than oilseed rape, we detected TuYV in many commonly grown weed species that share the fields and vegetation period together with canola crops in Czech and Slovak Republics. TuYV was detected by reverse-transcription polymerase chain reaction (RT-PCR) in at least 26 species including main crop hosts (oilseed rape), intercrops and weeds such as Amaranthus retroflexus, ...

Drug-Induced Liver Injury from Herbal Liver Detoxification Tea
We describe the case of a 36-year-old female who developed a clinically significant acute liver injury with a cholestatic pattern due to an over-the-counter herbal liver detox tea. This is the first case reported of a hepatotoxic effect from any of these compounds or ingredients in the detox tea: burdock root, stinging nettle leaf, cleavers herb, dandelion root, lemon peel, and lemon myrtle leaf (Backhousia citriodora). Idiosyncratic drug-induced liver injury (DILI) remains poorly understood; however, recognizing potential toxins is imperative to understanding toxicogenomics and identifying those at risk.Case Rep Gastroent...

Molecules, Vol. 27, Pages 7641: Isolation of a New Polysaccharide from Dandelion Leaves and Evaluation of Its Antioxidant, Antibacterial, and Anticancer Activities
Wu Junrui Wu Dandelion, in China, has a long history as a medicinal and edible plant, and possesses high nutritional and medical value. The present study aimed to isolate a new polysaccharide (DLP-3) from dandelion leaves and to evaluate its antioxidant, antibacterial, and anticancer activities. The structure of DLP-3 was analyzed using HPLC, FT-IR, SEM, GC-MS, and NMR spectroscopy. DLP-3 mainly consisted of Man, Rha, GlcA, Glc, Gal, and Ara with molar ratios of 2.32, 0.87, 1.21, 3.84, 1.00, and 1.05, respectively, with a molecular weight of 43.2 kDa. The main linkages of DLP-3 contained (1&rarr;4)-&...
