Simultaneous and ultra-sensitive detection strategy of Cu2+ and Mg2+ in wine and beer was developed based on dual DNA tweezers and entropy-driven three-dimensional DNA nanomachine. The dual DNAzyme can simultaneously respond to two kinds of metal ions and cause two kinds of "turn-on" fluorescent signals. The working principle of this strategy was indirectly proven. In addition, some key experimental parameters were also optimized. Under the optimum conditions, the limit of detection was 10 pM for Cu2+ and 2 nM for Mg2+ respectively which was significantly improved by entropy driven amplification. This strategy also showed good selectivity and specificity. It was successfully used to detect of Cu2+ and Mg2+ in wine and beer with 5.26% to 9.12% of relative standard deviation and 90.4% to 110.5% of recoveries.The perchlorate levels in 330 foods belonging to 5 varieties obtained from Wuhan were monitored. An ultra-high performance liquid chromatography coupled with triple quadrupoles mass spectrometry in combination with Cl18O4- internal standard method was performed to determine the level of perchlorate in various foods. Hereafter, dietary exposure and risk assessment of perchlorate was evaluated. The results revealed that the average level of perchlorate was 15.04 µg/kg with a detection of 95% among the whole food groups. The level of perchlorate in vegetables was the highest among the 5 varieties of food with an average content of 27.39 µg/kg, which in meat was the lowest with an average of 3.65 µg/kg. Estimated dietary intake results illustrated that males showed exposure in the range 0.004-0.18 µg/kg bw/day, which for females was 0.01-0.21 µg/kg bw/day. The results indicated that exposure to perchlorate via the food consumption for Wuhan people was evaluated as safe.Furan and 5-hydroxymethylfurfural (5-HMF) were quantified in 108 coffee models prepared considering the species/origin of the coffee beans, roasting temperature/time, mesh size used to sieve the ground coffee beans, type of extraction water and extraction method. The effect of drinking conditions, such as adding sugar or cream, on furan and 5-HMF levels, was also studied. The range of furan and 5-HMF in coffee samples were 5-362 ppb and 51-1143 ppm, respectively. Furan levels were increased by 198-560% with increasing roasting temperature/time and by 106-399% in cold-brew extracts compared with espresso extracts. Among the mesh sizes used, 500 μm with espresso extraction, and 710 μm with cold-brew extraction led to maximal furan levels. 5-HMF concentration was highest in Robusta coffee and espresso extracts, and decreased by 17-76% with increasing roasting temperature/time. In a drinking condition study, furan level was remained unchanged, even when sugar or cream were added.A fucoidan SFP, having novel structure, was extracted from Sargassum fusiforme. It had a molecular weight of 703 kDa and was composed of fucose and galactose with the ratio of 73.1626.84 (mol%). Structural analyses showed that it mainly consisted of 1,3-, 1,4-, 1,3,4-linked-α-l-Fucp and 1,3-, 1,6-linked-β-d-Galp, with partial sulfation at C-4, C-3 of fucose units and C-6, C-3 of galactose units. The branches consisted of sulfated fucosyl and galactofucosyl oligosaccharides. The regulatory effects of SFP on the intestinal microbiota in high-fat diet-fed mice were investigated. The high-dosage SFP exhibited good hypolipidemic effects, especially in regulating the high-densitylipoproteincholesterol, non-esterified fatty acid levels and lipase activity. It also significantly decreased the ratio of phyla Firmicutes/Bacteroidetes (P less then 0.05). Besides, SFP had certain effects on the richness and diversity of intestinal microbiota. Therefore, SFP exhibited novel structure and certain beneficial effects on the disorder of intestinal microbiota in high-fat diet-fed mice.
New treatments for acute ischaemic stroke, such as mechanical thrombectomy, can achieve reperfusion of large ischaemic tissue. Some studies have suggested that reperfusion therapies can increase the risk of suffering acute symptomatic seizure (ASS) and poststroke epilepsy (PSE). The aim of the study was to determine the incidence of ASS and PSE in patients undergoing thrombectomy, and related factors.

This was a retrospective single-centre study including patients with ischaemic stroke and NIHSS> 8 treated with thrombectomy with a follow-up ≥5 years. We evaluated several epidemiological, radiological, clinical and electroencephalographic variables.

Of the 344 included patients, 21 (6.1%) presented ASS, 53 (15.40%) died in the acute phase, and 13 (4.46%) died during the first year. The degree of reperfusion (p 0.029), advanced age (p 0.035), and haemorrhagic transformation (p 0.038) increased the risk of suffering ASS, with degree of reperfusion being an independent factor, OR 2.02 (1.21-4.64). CDK inhibitor The incidence of PSE was 4.12% in the first year, 3.72% in the second, and 1.61% in the fifth. The accumulated incidence at 5 years was 8.93%. Related risk factor for suffering PSE was ASS (p < 0.001), yielding an OR value of 2.00 (1.28-3.145).

Thrombectomy doesn´t increase the risk of ASS. A higher percentage of reperfusion, advanced age, and haemorrhagic transformation are associated with an increased risk of ASS. ASS is a risk factor for suffering PSE. In terms of mortality, having suffered ASS and/or PSE does not increase acute or long-term mortality.

Tanshinone, as a secondary metabolite, is synthesized under salt stress or other environmental stresses. Oxidative stress is an important physiological response of plants to salt stress. Transcription factors (TFs) are believed to play regulatory roles in this process, and AP2/ERF TFs have significant effects on defense against the adversity of plants. However, investigations on the regulation of AP2/ERF TFs in tanshinone synthesis under salt stress are limited. In this research, the tanshinone content, related gene expression and activities of enzymes, and the markers of oxidative stress were determined. The results showed that SmAP1, SmAP2 and SmERF2 were AP2/ERF TFs with AP conserved sequences, whose relative expression levels increased and were positively correlated with the contents of tanshinone I (T-I), tanshinone IIA (T-IIA) and cryptotanshinone (CT) in the roots of Salvia miltiorrhiza.
