The structural and optical properties were investigated. The X-ray diffraction (XRD) results confirmed the presence of the monoclinic phase in all the samples. The Fourier-transform infrared analysis gave the expected chemical combustion results of the final product with few traces of Ca3Al2O6 impurities at low and very high Potential of Hydrogen (pH). The XRD patterns showed the presence of an impurity phase at low pH. This impurity phase was caused by preferential precipitation in the starting mixture due to a lack of homogeneity in the precursor mixture between the urea and metallic ions hence poor combustion. The diffraction angles of the major peaks shifted to lower 2θ for all the samples except for the sample synthesized at pH = 3.4 which shifted to higher 2θ. The crystallite sizes of the as-prepared samples were determined using the Debye-Scherrer equation. It was noted that there was variation in the crystallite sizes with a change in pH. The effect of pH was also observed in the Ultraviolet-Visible (UV-Vis) studies. It was also noted that the band gap increased with an increase in pH from 2.9 to 4.5. Scanning electron microscope (SEM) micrographs showed that all samples were agglomerated and had irregular shapes with pores and cracks. The study provides a simple route to synthesize CaAl2O4: Eu2+, Dy3+ phosphors with the optimum synthesis pH producing the most crystalline sample for application in lighting devices.","PeriodicalId":513497,"journal":{"name":"Trends in Sciences","volume":"36 27","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141800139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple matrices have been formulated, with the SrAl2O4:Eu2+,Dy3+matrix being the most extensively studied due to its superior optical and structural properties. In this work, the objective of synthesizing SrAl2O4:Eu2+,Dy3+particles was achieved by using a combustion approach. By optimizing the synthesis process and studying the impact of Dy3+concentrations on the structural and optical features, it has proven feasible to regulate the reaction and attain exceptional optical characteristics. The importance of this investigation is in assessing the practical feasibility of using such a material. This study examines a phosphor composed of strontium aluminate (SrAl2O4) that is activated using various amounts of Dy3+(ranging from 0.1 to 0.8 mol % ). The study’s findings of XRD showed that the SrAl2O4:Eu2+,Dy3+samples  had a monoclinic phase of   space group P21. Increase in the dopant concentration, the size of the crystallites in SrAl2O4:Eu2+,Dy3+ samples decreased, as determined by Scherer's formula and the Williamson-Hall plot.

The results showed that the bandgap energy decreased from 6.5 to 5.5 eV as the level Dy3+rose from 0.1 to 0.8 mol % . FT-IR spectroscopy revealed a prominent vibrational stretching at 570 cm-1, which is likely due to the Al-O bond, and another stretching at 1049 cm-1, related to the Sr-O bonds of SrAl2O4:Eu2+,Dy3+ NPs.","PeriodicalId":513497,"journal":{"name":"Trends in Sciences","volume":"43 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141805791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess the efficacy of aqueous (AE), methanolic (ME), ethanolic (EE), ethyl acetate (EAE), and chloroform (CE) crude extracts derived from green chiretta in controlling Meloidogyne enterolobii and M. incognita under laboratory conditions. The results demonstrated significant inhibitory effects of all crude extracts, except for CE, against both nematode species. Notably, AE (10 and 20 mg/mL), ME (20 mg/mL), and EE (20 mg/mL) treatments exhibited maximum inhibition of hatching, leading to a considerable reduction in nematode hatch rates by 87.5 - 96.8 % for M. enterolobii and 88.5 - 96.5 % for M. incognita, compared with distilled water (DW). In terms of second-stage juveniles (J2s) mortality, AE (10 and 20 mg/mL), ME (20 mg/mL), and EAE (20 mg/mL) demonstrated the highest nematicidal activity, resulting in mortality rates of 94.2 - 100 % for M. enterolobii and 92.2 - 99.2 % for M. incognita. Chemotaxis assays revealed a repellent effect of all extracts on both nematode species, except for the ethyl acetate extract (EAE), which attracted M. incognita J2s without affecting M. enterolobii J2s. The observed efficacy was attributed to the higher concentrations of bioactive compounds, including flavonoids, phenolics, and terpenoids, in the extracts compared to CE. Based on these in vitro findings, it is suggested that AE, ME, EE, and EAE of green chiretta exhibit significant nematicidal activity against M. enterolobii and M. incognita. Further evaluation under greenhouse and field conditions is warranted to ascertain the practical applicability and effectiveness of these extracts in a real-world agricultural setting.","PeriodicalId":513497,"journal":{"name":"Trends in Sciences","volume":"60 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141807559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major molecular sensors for hypoxia at the cellular level are hypoxia inducible factor and heme oxygenase. Hypoxia also acts on the vasculature directly conveying its damaging effects through disruption of the control of vascular tone, particularly in the coronary circulation, enhancement of inflammatory responses and activation of coagulation pathways. These effects could be particularly detrimental under pathological conditions such as obstructive sleep apnea and other breathing disorders. Introduction: The effect of conjugate 2-(3,4-Dihydroxyphenyl)-6-{[1-(2’-bromo-3’,4’-dimethoxyphenyl)-6,7-dimethoxy-3,4-dihydroisoquinolin-2(1H )-yl]methyl}-3,5,7-trihydroxychroman-4-one (DHQ-11) on hypoxia-induced vasorelaxation was investigated in rat aortic rings using standard organ bath techniques.  Materials and methods: Hypoxia was stimulated by a superfusion of aortic rings with a glucose-free Krebs solution bubbled with 95 % N2/5 %  CO2. The effect of conjugate DHQ-11 was assessed after a 60- min period of hypoxia on aortic rings precontracted with 50 mm KCl or 1µM phenylephrine (PE). The conjugate DHQ-11 significantly attenuated hypoxia-induced vasorelaxation in the endothelium-intact aortic rings precontracted with KCl or PE in a concentration-dependent manner. Results and discussion: This effect of conjugate DHQ-11 was more potent in aortic rings precontracted with PE than those with KCl where it maximally reduced hypoxia-induced vasorelaxation from 44.7 ± 3.7  to 5.4 ± 3.7  and 33.9 ± 3.4 to 10.8 ± 4.2 %, respectively. The removal of the endothelium attenuated the effect of conjugate DHQ-11 on hypoxia-induced vasorelaxation. Similarly, pretreatment of endothelium-intact aortic rings with L-NAME and methylene blue also attenuated the effect of conjugate DHQ-11 on hypoxia-induced vasorelaxation. Furthermore, the blockade of the ATP-sensitive KATP channel with glibenclamide and the calcium-activated large conductance BKCa channel with TEA also significantly attenuated the effect of conjugate DHQ-11 on hypoxia-induced vasorelaxation. Collectively, these results indicated that conjugate DHQ-11 attenuated the hypoxia-induced vasorelaxation suggesting that it alleviated the oxidative damage of vasculature. Conclusions: This effect of conjugate DHQ-11 possible is mediated through several mechanisms including the blockage of the extracellular Ca2+ entry via the voltage-dependent and receptor-operative Ca2+ channels, as well as inhibition of sarcoplasmic reticulum Ca2+ release via the inositol triphosphate pathway. In addition, endothelium and NO/sGC/cGMP/PKG pathway, as well as KATP and BKCa channels most likely participate in protection by conjugate DHQ-11 against hypoxia-induced vasorelaxation.","PeriodicalId":513497,"journal":{"name":"Trends in Sciences","volume":"39 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141809820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives of this study were to determine the suitability of the different Job’s varieties of Job’s tears in Sa Kaeo province, East of Thailand and then to select a possible variety to evaluate its chemical properties. Then, the data will be used for the conservation and cultivation of Job’s tears in Thailand. Seven varieties of Job’s tears were collected from markets in Thailand from different sources such as Luang Phra Bang province in the Lao People’s Democratic Republic, Nong Khai, Loei and Chiang Rai provinces in Thailand. Firstly, 7 varieties of Job’s tears were grown and the plant growth characteristics were collected to evaluate their adaptability in Sa Kaeo province, Thailand. Secondly, the plant growth characteristics of 4 varieties of edible Job’s tears were recorded chemical properties such as their chemical composition, total phenolic content (TPC), total flavonoid compounds (TFC), DPPH radical scavenging assay, ABTS decolorization scavenging effect and potassium ferricyanide reducing power assay. The statistical data were analyzed by using the one-way analysis of variance (ANOVA) to determine the difference between varieties. The results showed that there are differences between the varieties in plant morphology and chemical properties. Seven Job’s tears plants were classified into 2 groups, an edible and an ornamental group. The Job’s tears seeds of the ornamental group could not be dehulled into kernels.
