Anticancer and Antioxidant Activities of Biologically Active Newly Synthesized α-Amino Acid-Dithiocarbamate Complexes of Some Bivalent Metals
Authors: Kaviyarasi P. , Manivannan S. 
Published: December 2023

The present study focuses on the synthesis and characterization of L-proline dithiocarbamate and its L-prodtc metal(II) (M = Ni2+, Cu2+ and Se2+) complexes. The ligand was synthesized in the presence of an alkali through the reaction of one mole of carbon disulphide and L-proline in ethanol under ice cold condition. The solubility of this ligand in the media is attributed to its high hygroscopic character and therefore, its metal(II) complexes were synthesized using a freshly prepared ligand. The characterization of the metal(II) complexes were carried out by molar conductance, magnetic susceptibility, elemental analysis, TGA/DTA, mass, IR, Raman, UV-Visible, 1H and 13C NMR spectroscopic studies. The biological activity of all the metal(II) complexes has been examined using an inhibition method for bacteria and pathogenic fungus, which will assess their possible antibacterial, antioxidant, anticancer activities and anti-inflammatory. It has been observed that Se(L-Prodtc)2 exhibits anticancer activity against breast cancer cells (MCF7) and also observed that antioxidant activity of Se(L-Prodtc)2 is more as compared to standard BHT, whereas Cu(L-Prodtc)2 complex shows appreciable anti-inflammatory activity.

Published: December 2023

In this work, co precipitation method was adopted to synthesis Cu (0.01M, 0.02M, and 0.03M) doped CaSnO3 nanoparticles and the structural, optical, morphological and electrochemical characterization were studied using XRD, FTIR, UV–Visible, Photoluminescence, SEM and Cyclic voltammetry with Electrochemical impedance analysis. It is noticed from XRD patterns that the peaks shift towards higher angles attributed to the substitution of Cu2+ ions for Ca2+ ions, and confirms the orthorhombic structure of Cu2+ doped CaSnO3. The average crystallite size is found between 40 – 49 nm for Cu doping. FTIR analysis boosts the confirmation of Cu doping in to the CaSnO3 nanoparticles by the presence of vibrational peaks at 698 cm-1, 622 cm-1, and 581 cm-1 due to Cu-O stretching and the peak 483 cm-1 due to Sn-O stretching vibration. The calculated band gap values are 4.7 eV, 4.8 eV, and 4.9 eV for Cu doping. The PL emission study showed light emission towards the visible region. SEM analysis proved well-formed cubed particles about < 2µm. Specific capacitance values are highest for 0.02 M Cu doped CaSnO3 at about 1694F/g, compared to 572 F/g, 922 F/g, and 1626 F/g for pure, 0.01 M, and 0.03 M Cu doped CaSnO3 particles, respectively, at a scan rate of 10 mV/s. Overall, these findings indicate that 0.02 M and 0.03 M Cu doped CaSnO3 are promising candidates for energy storage applications.

Published: December 2023

The phase transfer catalyst 1-benzyl-1,4-diazoniabicyclo[2.2.1]hepta-2,4(7)-dienedichloride (BDHDC) in organic chiral synthesis was used in this study. Kinetic parameters such as ultrasonication effect, phase transfer catalyst dose, solvents, butyl chloride volume, stirring speed and weight of KOH were examined for the phase transfer catalytic reactions. The reaction between phenyl acetonitrile and butyl chloride was carried out under basic conditions and ultrasonic irradiation (300 W, 40 kHz) using BDHDC as a phase transfer catalyst. The introduction of BDHDC catalyst significantly improved the overall reaction, resulting in a high yield of the chiral combination. The product formation has been optimized by modifying the kinetic parameters.

In the current scenario, environmental friendly methods of synthesizing nanoparticles and their composites have become a desirable trend. Phytochemicals derived from plant extracts are now being employed as a distinctive method for synthesizing nanoparticles due to their ability to serve as both reducing and capping agents. In present study, copper oxide nanoparticles (CuO NPs), zinc oxide nanoparticles (ZnO NPs) and their mixed composites (CuO/ZnO) were synthesized using the flower extract of plant Cassia alata. The synthesis of nanoparticles was confirmed by observing the colour change of the reaction mixture and was determined by detecting the surface plasmon resonance band at 280, 320 and 359 nm for CuO, ZnO and CuO/ZnO, respectively. The antioxidant activity of nanoparticles was characterized for DPPH, ABTS, NO and iron reducing power method. In addition, the antibacterial properties of these bioactive nanoparticles were also investigated. The CuO/ZnO nanocomposites showed superior antioxidant and antibacterial activity than CuO and ZnO nanoparticles.

Published: December 2023

Rare-earth orthoferrites are a group of compounds which exhibit improved magnetic, optical, and electrical characteristics throughout a wide range of temperatures. In present work, dysprosium based orthoferrite compound containing double phase of DyFeO3 perovskite/ Dy3Fe5O12 garnet was synthesized via co-precipitation technique. A mixed phase of orthoferrite, DyFeO3 perovskite and Dy3Fe5O12 garnet has been obtained. The X-ray diffraction (XRD) was carried out to explore the structural arrangements of atoms in the prepared material and clearly demonstrated the presence of both cubic phase of Dy3Fe5O12 (bcc) and orthorhombic phase of DyFeO3 in the powder sample. The nanoparticles surface morphological behaviour is explored with field emission scanning electron microscope (FE-SEM), which shows nearly spherical shape particles with little agglomeration. Using the UV-visible absorbance, band gap of the prepared sample was evaluated as 2.06 eV from Tauc plot. The magnetization behaviour was observed using a vibrating sample magnetometer (VSM), which revealed the Langevin component (ferromagnetic) at low field and as linear component (antiferromagnetic) at high field. The electric polarization (P-E loop) studies also revealed the typical induced ferroelectric behaviour.

Authors: Kanimozhi A. , Bakkialakshmi S. 
Published: December 2023

The binding of L-tryptophan (L-Trp) and hesperidin (HES) was investigated by UV, fluorescence, synchronous fluorescence, time-resolved fluorescence, Fourier transform infrared (FTIR) spectroscopies, FRET, antibacterial activity, anticancer activity and molecular docking study. The flavonoid glycoside known as hesperidin has been shown to have therapeutic properties for a variety of disorders, including cancer diseases. Its low solubility and bioavailability cause it to be little absorbed, which means that a delivery mechanism is necessary in order for it to reach its therapeutic goal. Fluorescence data revealed that the fluorescence quenching mechanisms of L Trp by hesperidin are all static quenching procedures. Synchronous fluorescence spectroscopy shows the interaction between hesperidin and L-Trp changes the hydrophobicity of the microenvironment of tryptophan (Trp) residues. The anticancer activity effect of hesperidin and L-Trp on human cervical cancer cell lines was assessed using MTT and crystal violet assays.

Comparison of the Property Players’ Preferences on Housing Prices in Surabaya
Authors: Muktiwibowo Sebastian Arif , Anastasia Njo 
Published: December 2023

A landed house is a real estate product that is used to fulfill consumption or investment motives. This study was conducted to compare the preferences of developers, consumers, and investors for housing prices in Surabaya on both motives. Respondents were selected by purposive sampling and obtained 417 respondents. Data collection through questionnaires was conducted offline to developers and online to consumers and investors. Test data used Kendall concordance and Kruskal Wall test to analyze the comparison of developer, consumer, and investor preferences. The results showed that the three players had different preference variables on house prices in Surabaya related to physical quality, brand, location concept, location environment, financial condition, and livability. Developers focus on products (physical quality and housing concept) and brands. Consumers prioritize physical quality, location environment, and financial condition. Furthermore, investors prioritize the physical and environmental quality of the location. Physical quality is a key preference among developers, consumers, and investors. These findings indicate that each party has their own prioritized interests, so their preferences differ according to their motives.
“By the way I want to give you some masks”: exploring multimodal stance-taking in YouTube videos
Authors: Ho Wing Yee Jenifer 
Published: December 2023

Abstract
While the effectiveness of facemasks against COVID-19 has now become largely uncontroversial, at the beginning of the global pandemic, wearers of facemasks were often the target of sometimes racially tinged attacks. Wearing facemasks (or not) became not just a question of science, but evolved into a more complex issue of social identity, morality and global citizenship embedded within the “tribal thinking” of mask-wearers and non-mask-wearers. This paper explores to what extent two bilingual YouTube influencers participated in either accentuating or softening of boundaries of the two “tribes” by embedding facemasks in their videos. Based on multimodal transcriptions of the two videos (Wang, Yilei, Dezheng Feng & Wing Y. J. Ho. 2021. Identity, lifestyle, and face-mask branding: A social semiotic multimodal discourse analysis. Multimodality & Society 1(2). 216–237), three moments were identified where facemasks were employed by the social actors to perform everyday activities, such as grocery shopping and family brunch. I then examine the interactional stances (Dubois, John W. 2007. The stance triangle. In Robert Englebretson (ed.), Stancetaking in discourse: Subjectivity, evaluation, interaction, 139–182. Amsterdam: John Benjamins) taken by the actors towards facemasks through language and other semiotic resources. By exploring their multimodal stance-taking, it is argued that the two YouTubers’ intercultural trajectories, their performances of authenticity, and their established influence on social media provided them unique means for participating in tribalizing discourses around facemasks by making perceived differences between different groups materials for cultural consumption. The paper concludes by discussing the opportunities and challenges of vernacular health communication through social media influencers.
The association between parental SARS-CoV-2 infection in pregnancy and fetal growth restriction
Authors: Mitta Melanie , Holt Lauren , Chandrasekaran Suchitra , Dude Carolynn 
Published: December 2023

Abstract

Objectives
Although the relationship between maternal viral infections and fetal growth restriction (FGR) is well established, the association between SARS-CoV-2 infection in pregnancy and FGR remains unclear. We investigated the association between SARS-CoV-2 infection in pregnancy and FGR at a single county hospital.

Methods
We performed a prospective cohort study with cohorts matched by gestational age and month of SARS-CoV-2 PCR testing between April 2020 and July 2022. Individuals were included if they had a SARS-CoV-2 PCR testing up to 32 weeks of gestation and had a third trimester ultrasound. Primary outcome was a diagnosis of FGR, while secondary outcomes were rates of preeclampsia, small for gestational age (SGA) and birthweight. Univariate analyses, chi-square test and logistic regression were used for analysis.

Results
Our cohorts constituted of 102 pregnant individuals with a positive SARS-CoV-2 PCR test result and 103 pregnant individuals with a negative SARS-CoV-2 PCR test result in pregnancy. FGR rates were 17.8 % and 19.42 % among positive and negative SARS-CoV-2 cohorts respectively. While a statistical difference in preeclampsia rates was noted (34.31 % vs. 21.36 %, p=0.038) between cohorts, odds of getting preeclampsia based on SARS-CoV-2 test result was not significant (aOR 1.01, CI=0.97–1.01, p=0.75). No statistical difference was noted in demographics, FGR and SGA rates, and birthweight.

Conclusions
Our findings suggest no association between SARS-CoV-2 infection in pregnancy and FGR at a single institution. Our results validate emerging data that additional fetal growth ultrasonographic assessment is not indicated solely based on SARS-CoV-2 infection status.
