Porphyromonas gingivalis: exactly where can we stand it our battle against this mouth virus?
We utilize the approach on an aqueous solution containing eosin Y and a trace amount of bromocresol green. The presence of bromocresol green with the concentration as low as 400 nM can be revealed via the cross peaks in the resultant 2D asynchronous spectra. In a preliminary study, we suggest that 2D disrelation spectrum might provide an alternative chance to reveal the presence of small amount bromocresol green. V.RNA as a carrier of genetic information plays a critical role in various physiological processes. RNA-rich nucleolus is usually employed as an important biomarker for many malignant diseases. Herein, RNA-responsive fluorescent carbon dots (CDs) were synthesized by a simple microwave method. Due to the presence of cationic benzothiazolium groups in the CDs, a "turn-on" fluorescence signal was achieved between CDs and RNA. The CDs exhibit excellent RNA selectivity and a good linear relationship with a detection limit of 0.62 μg/mL. The small particle size, polarity sensitivity and RNA response behavior of CDs realized fast and wash-free nucleolus imaging effectively. Overall, these CDs provide a powerful potential tool for monitoring cell nucleus activity and elucidating RNA dynamics. V.The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) associated disease (COVID-19) outbreak seriously challenges globally all health care systems and professionals. Expert projections estimate that despite social distancing and lockdown being practiced, we have yet to feel the full impact of COVID-19. In this manuscript we provide guidance to prepare for the impact of COVID-19 pandemic on breast cancer patients and advise on how to triage, prioritize and organize diagnostic procedures, surgical, radiation and medical treatments. Macrophages are attractive therapeutic targets due to their contributions to many pathological processes including cancers, atherosclerosis, obesity, diabetes and other inflammatory diseases. Macrophage-targeted gene therapy is an effective strategy for regulating macrophage function at the site of inflammation to treat related diseases. Panobinostat However, macrophages are recognized as difficult to transfect cells and non-specific delivery would inevitably cause unwanted systemic side effects. Herein, we prepared a series of macrophage-targeted nanoparticles (NPs) using cationic lipid-like compound G0-C14 and different carbohydrates-modified poly(lactide-co-glycolide) (PLGA) or poly(lactide-coglycolide)-b-poly(ethylene glycol) (PLGA-PEG) for gene delivery by a robust self-assembly method. The yielded NPs were decorated with carbohydrate-based targeting moieties including mannose, galactose, dextran, and a mixture of mannose and galactose. EGFP messenger RNA (mRNA) and GFP plasmid DNA (pDNA) were used as reporter genes ions in macrophages also demonstrated more efficient mRNA transfection, suggesting that the NP-mediated mRNA transfection efficiency was consistent with the endocytosis results. Mulberry wine residues produced during the wine-brewing process contain several anthocyanins and other bioactive compounds. Therefore this study optimized the conditions for ultrasound-assisted enzymatic extraction of anthocyanins from mulberry wine residues. A three-level, four-factor Box-Behnken design was used to optimize the extraction conditions. Panobinostat Moreover, anthocyanins were determined using an ultra-performance liquid chromatograph coupled to a mass spectrometer (UPLC-MS). The mathematical model suggested a high coefficient of determination (R2 = 0.9475) for the optimum conditions, namely 52 °C, 315 W, 0.22% enzyme and 94 min incubation. The yield (5.98 mg/g) was close to the predicted value (5.87 mg/g). The two anthocyanins (cyanidin-3-O-glucoside and cyanidin-3-O-rutinoside) identified are consistent with those present in mulberry. The optimized conditions increased anthocyanin yield, through improved utilization of mulberry wine residues. The findings will potentially lead to a reduction in the environmental burden of this waste and improve the efficiency and productivity of the mulberry fruit processing industry. Pectin has several purposes in the food and pharmaceutical industry making its quantification important for further extraction. Current techniques for pectin quantification require its extraction using chemicals and producing residues. Determination of pectin content in orange peels was investigated using near infrared hyperspectral imaging (NIR-HSI). Hyperspectral images from orange peel (140 samples) with different amounts of pectin were acquired in the range of 900-2500 nm, and the spectra was used for calibration models using multivariate statistical analyses. Principal component analysis (PCA) and linear discriminant analysis (LDA) showed better results considering three groups low (0-5%), intermediate (10-40%) and high (50-100%) pectin content. Partial least squares regression (PLSR) models based on full spectra showed higher precision (R2 > 0.93) than those based on few selected wavelengths (R2 between 0.92 and 0.94). The results demonstrate the potential of NIR-HSI to quantify pectin content in orange peels, providing a valuable technique for orange producers and processing industries. Alginate is the main component of brown algae which contributes to a huge biomass. The alginate oligosaccharides (AOs) have been widely used in food, cosmetic and pharmaceutical industries due to their various physiological activities. In this study, we expressed and characterized a novel PL-6 alginate lyase, named OUC-ScCD6. The results indicated that OUC-ScCD6 showed highest activity at 50 °C and pH 9.0. OUC-ScCD6 prefers to degrade poly M blocks and could digest poly G blocks as well. Endolytic action mode towards polysaccharides contributes to the creation of AOs with the degrees of polymerization 2-6. Degradation towards saturated oligosaccharides showed that saturated trisaccharides (M3 and G3) were minimum identifiable substrates. Furthermore, OUC-ScCD6 shows an even-numbered glycosidic bonds preference from non-reducing end which provided clearer insights into the substrate recognition and action mode of PL-6 family alginate lyases.
