Overall, thickened cell wall and methylated pectin have synchronicity in spatial location of roots, and their coordination contributed to Cd accumulation in S. alfredii.This article conceptualises the problem of selecting teaching content that supports the practice of programme evaluation. Knowledge for evaluation practice falls within one of three categories of knowledge that are defined by the different roles they play in supporting practice. First, core knowledge relates to the defining activity of evaluation practice, i.e., that it informs the intellectual task of the determination of a programme's value. Second, accessory knowledge informs activities that support and facilitate the concretisation of the previous activity in a delivery context (e.g., stakeholder participation, evaluation use, project management, etc.). Third and finally, supplementary knowledge informs activities that may, on occasion, occur during evaluation practice, but without relating to the determination of value, either inherently or in a support role. The selection of knowledge for the teaching of evaluation must match the knowledge needed for the pursuit of effective evaluation practice core, accessory, and supplementary knowledge. The specifics of these three needs ultimately depend on the characteristics of a given practice. The selection of content for the teaching of evaluation should ideally address these specific needs with the best knowledge available, regardless of its disciplinary origins.A comparison of high-performance liquid chromatography (HPLC) and solid-phase extraction (SPE) methods is carried out for the simultaneous analysis of indoxyl sulfate and sodium butyrate in plasma using Phenyl (250 × 4.6 mm; 5 µm) and SunShell (150 × 4.6 mm, 2.6 µm) columns with mobile phases ammonium acetate (20 mM)-ACN (955, v/v) and water-ACN (9010), respectively. The values of the retention, separation and resolution factors for indoxyl sulfate and sodium butyrate were 3.1, 1.29 and 2.0 with phenyl and 1.0, 1.55 and 1.60 with SunShell columns. The values of the theoretical plates were in the range of 650 to 1600 while the tailing factors were 0.98 to 1.0. The limits of the detection and quantification of sodium butyrate and indoxyl sulfate were 0.1-1.9 and 0.43-9.2 µg with these columns. The hydrogen bondings and π-π interactions were responsible for the separation of these molecules. The multi-wall carbon nanotubes (MWCNTs) served as a good sorbent in SPE extraction. The developed SPE and HPLC methods were quick, robust, exact and economic for the analysis of indoxyl sulfate and sodium butyrate. The reported SPE and HPLC methods can be useful to determine the reported molecules in plasma.In this work, we present a computational study on 105 selected organic molecules in order to find suitable candidates for using as thermally activated delayed fluorescent (TADF) emitters in organic light emitting diodes (OLEDs), in the emission range of red light. Based on time-dependent density functional theory (TD-DFT) computations, three promising candidates were found, predicted to have low singlet-triplet splittings, lower than 0.06 eV, and TADF rates of 0.124, 0.154 and 0.231 1/μs. Then, using an experimental-theory calibration approach, the emission wavelength of the molecules were estimated to be 570, 476, and 623 nm, respectively. For the molecule whose emission wavelength (623 nm) is predicted to be in our desired range, we measured the photoluminescence (PL) spectrum and find out that its emission peak is within the predicted accuracy of the employed method. Moreover, we benchmarked the performance of density functional based tight-binding (DFTB) method for future screening works and find out that, this method is an efficient pre-screening tool, useful in searching for molecules with desired emission wavelengths.We combined the virtues of mesoporous silica and organic functional groups to develop a hybrid fluorescent sensor, PyU-SBA-15, with excellent ability to detect Hg2+ in aqueous medium with high selectivity. In this sensor, the pyrene fluorophore acts as the reporter and the urea unit acts as the receptor during Hg2+ determination. The control material, PyH-SBA-15, which lacks a carbonyl group in the receptor portion, did not display metal-ion selectivity, thereby demonstrating that introducing an additional metal-chelating unit is necessary to improve the metal-ion selectivity of the hybrid sensor. When the concentration of Hg2+ was increased, the fluorescence emission intensities of PyU-SBA-15 at 379, 398, and 476 nm gradually decreased. The emission intensity at 379 nm was linearly proportional to Hg2+ concentrations in the range of 0-1.0 × 10-4 M, and the sensor was determined to have a detection limit of 9.92 × 10-8 M. This work provides an effective strategy for improving or modulating the metal-ion selectivity of fluorescent sensors based on organic-inorganic hybrid mesoporous silica systems.A simple, selective and sensitive method is proposed for determination of cysteine (Cys) in milk samples using ionic liquid functionalized silver nanoparticles (ILs-AgNPs) as a colorimetric probe. ILs-AgNPs was synthesized by simple reduction method using silver nitrate as a precursor and sodium borohydride as a reducing agent and functionalized with ILs to prevent particles from self-aggregation. The sensing mechanism has been dependent on the color change of ILs-AgNPs and red shift of absorption band from 395 nm to 560 nm in the visible region, which is found proportional to the concentration of target analyte in sample. ILs-AgNPs was characterized in absence and presence of Cys by UV-vis, Fourier transform-infrared (FTIR) spectroscopy, transmission electron microscope (TEM) and dynamic light scattering (DLS). The linear range was acquired in the range of 0-100 ng mL-1, with correlation coefficient (R2) of 0.996 and limit of detection (LOD) of 4.0 nM. The binding mechanism and interactions between Cys and ILs-AgNPs was confirmed by calculating the binding constant and thermodynamic parameters such as enthalpy (∆H), entropy (∆S) and Gibb's free energy (∆G). The use of ILs-AgNPs exhibited high colorimetric selectivity for Cys in milk samples in presence of other amino acids. This proposed strategy possessed the advantages of simplicity and selectivity, hence is applied for analysis of Cys in milk samples.Strawberries (Fragaria × ananassa Duch.) are one of the most economically important fruit crops worldwide, several commercially viable cultivars are cultivated in the northern region of Thailand. The morphological characters at the young vegetative seedling stage can be very similar, which has hindered breeding efforts. The present study assesses the ability of random amplification of polymorphic DNA (RAPD) markers and metabolomics techniques to distinguish six strawberry cultivars. Both techniques showed congruent results for the leaf tissue and classified the cultivars into three major clusters. For the most different cultivars, Akihime and Praratchatan No.80, fruits were analysed at eight fruit ripening stages. The data highlighted a broad biological variation at the early ripening stages and less biological variation at the mature stages. Key metabolic differences included the polyphenol profile in Praratchatan No.80 and fatty acid synthesis/oxidation in Akihime. In summary, the RAPD and metabolite data can be used to distinguish strawberry cultivars and elucidate the metabolite composition of each phenotype. MitoSOX Red This approach to the characterisation of genotypes will benefit future breeding programmes.The prevalence of obesity is increasing rapidly globally and has recently reached pandemic proportions. It is a multifactorial disorder linked to a number of non-communicable diseases such as type-2 diabetes, cardiovascular disease, and cancer. link2 Over-nutrition and a sedentary lifestyle are considered the most significant causes of obesity; a healthy lifestyle and behavioural interventions are the most powerful ways to achieve successful weight loss, but to maintain this in the long term can prove difficult for many individuals, without medical intervention. Various pharmacological anti-obesogenic drugs have been tested and marketed in the past and have been moderately successful in the management of obesity, but their adverse effects on human health often outweigh the benefits. Natural products from plants, either in the form of crude extracts or purified phytochemicals, have been shown to have anti-obesogenic properties and are generally considered as nontoxic and cost-effective compared to synthetic alternatives. These plant products combat obesity by targeting the various pathways and/or regulatory functions intricately linked to obesity. Their mechanisms of action include inhibition of pancreatic lipase activities, an increase in energy expenditure, appetite regulation, lipolytic effects, and inhibition of white adipose tissue development. In this review, we discuss the distinct anti-obesogenic properties of recently reported plant extracts and specific bioactive compounds, along with their molecular mechanisms of action. This review will provide a common platform for understanding the different causes of obesity and the possible approaches to using plant products in tackling this worldwide health issue.Five undescribed sesquiterpene coumarins, one undescribed coumarin derivative, and twenty-five known analogues, were isolated from the resin of Ferula sinkiangensis K.M.Shen. link3 The planar structures and relative configurations of the undescribed compounds were determined by NMR experiment and HRESIMS data. The absolute configurations were established by Electrostatic Circular Dichroism method. Among these analogues, Sinkiangenol E showed the best cytotoxic activity against HeLa cervical cancer cells. Annexin V-FITC/PI staining indicated that Sinkiangenol E induced apoptosis in HeLa cells. Cell cycle analysis showed Sinkiangenol E arrested cell cycle at G0/G1 phase. Western blot results proved that Sinkiangenol E affected apoptosis-related and cell cycle regulation-related protein expression by activating the MAPK pathway.Seven previously undescribed acridones, named atalantiaphyllines A-G, along with twenty-six known compounds were isolated from the dichloromethane extracts of roots and stems of Atalantia monophylla DC. Their structures were elucidated by analysis of extensive NMR and HRMS data. Aromatase inhibition, cytotoxicity against MOLT-3, HepG2, A549 and HuCCA-1 cell lines and DPPH radical scavenging activity of these compounds were evaluated. Most of the tested acridones exhibited higher potency in inhibiting aromatase than the positive control, ketoconazole, with IC50 values in the range of 0.08-2.0 μM. In the cytotoxicity assay, cycloataphylline A, N-methylbuxifoliadine E and atalantiaphylline G were selectively cytotoxic against MOLT-3 cell line with IC50 values of 8.0, 5.4 and 9.8 μM, respectively, while only atalaphyllidine exhibited highest antioxidant activity as evaluated by DPPH free radical scavenging assay with an IC50 value of 22.4 μM.Acute sentinel hypoxia-ischaemia in neonates can target the hippocampus, mammillary bodies, thalamus, and the basal ganglia. Our previous work with paediatric patients with a history of hypoxia-ischaemia has revealed hippocampal and diencephalic damage that impacts cognitive memory. However, the structural and functional status of other brain regions vulnerable to hypoxia-ischaemia, such as the basal ganglia, has not been investigated in these patients. Furthermore, it is not known whether there are any behavioural sequelae of such damage, especially in patients with no diagnosis of neurological disorder. Based on the established role of the basal ganglia and the thalamus in movement coordination, we studied manual motor function in 20 participants exposed to neonatal hypoxia-ischaemia, and a group of 17 healthy controls of comparable age. The patients' handwriting speed and accuracy was within the normal range (Detailed Assessment of Speed of Handwriting), and their movement adaptation learning (Rotary Pursuit task) was comparable to the control group's performance.
