Authors: Okello David K. , Deom C. Michael , Puppala Naveen 
Published: October 2022

Abstract‘Naronut 1R’ (Reg. no. CV‐150, PI 693985) is a high‐yielding, Spanish‐type groundnut (Arachis hypogaea L. subsp. fastigiata var. vulgaris) cultivar with a red seed coat and two seeds per pod. The cultivar was selected from a cross between International Crops Research Institute for the Semi‐arid Tropics advanced lines ‘ICGV‐SM 90704’ and ‘ICGV‐SM 86715’. Naronut 1R was developed for groundnut rosette disease resistance, late leafspot resistance, yield, red seed coat, and early maturity. Naronut 1R matures in 75–80 d after planting, compared with 90 d for the widely grown and popular landrace Erudu red (Spanish‐type groundnut). Naronut 1R has much higher yields (1,473 kg ha−1) than Erudu red (554 kg ha−1). The overall groundnut rosette disease rating was 44% lower in Naronut 1R (2.8 disease rating) compared with Erudu red (5.0 disease rating). Similarly, the overall late leafspot disease rating was 28% lower in Naronut 1R (3.6 disease rating) compared with Erudu red (5.0 disease rating). Similar to Erudu red, Naronut 1R seed testa is red, but the seed is larger. The sound mature kernel weight was 9.42% higher for Naronut 1R than for Erudu red. The shelling percentage for Naronut 1 was 49.3%, whereas Erudu red was 60%. Naronut 1R has lower protein (18.1 vs. 21.3%) and oil content (36.0 vs. 44.3%) than Erudu red. Naronut 1R will allow for broad adoption of a high yielding, early maturing, red seed coat cultivar that carries resistance to groundnut rosette disease and late leaf spot disease.

AbstractLeaf area index (LAI) is a vital parameter reflecting vegetation structure, physio‐ecological process and growth development. Accurate estimation of mangrove LAI is fundamental for assessing the ecological restoration and sustainable development of mangrove ecosystems. To date, very few studies have explored the hybrid method of radiative transfer model (RTM) and machine‐learning model in retrieving mangrove LAI with different satellite sensors. This study investigated the capabilities of combining the PROSAIL‐D model, XGBoost (extreme gradient boosting) and remote sensing images in estimating mangrove LAI, considering the spatial resolutions and spectral vegetation indices (VIs) of Landsat‐8, Sentinel‐2, Worldview‐2 and Zhuhai‐1 images, and further explored the role of eco‐environmental factors in the spatial distribution of LAI in Gaoqiao Mangrove Reserve, China. The results showed that the Zhuhai‐1 acquires the best estimation accuracy ( (the determination coefficient of validation) = 0.86, RPD (residual prediction deviation) = 3.36 and RMSE (root mean square error) = 0.31), followed by Worldview‐2 ( = 0.84, RPD = 2.64 and RMSE = 0.33), Sentinel‐2 ( = 0.34, RPD = 1.33 and RMSE = 0.62) and Landsat‐8 ( = 0.29, RPD = 1.03 and RMSE = 0.71). The newly developed three‐band VIs ( with Landsat‐8, with Sentinel‐2, with Worldview‐2 and with Zhuhai‐1) were efficient estimators of mangrove LAI. Moreover, elevation and species composition could greatly affect the spatial distribution of mangrove LAI. We concluded that the hybrid method of PROSAIL‐D and XGBoost model using VIs derived from Zhuhai‐1 hyperspectral image could be deemed as basic method and input variables of mapping mangrove LAI, and could be effectively and widely applied in generating mangrove LAI products at the regional and national scales.

By replacing traditional methods to more sustainable and greener approaches, multicomponent reactions are the rapid and efficient tool for the synthesis of organic molecules of structural diversity and complexity. Heterocyclic chemistry transforms small set of precursors into series of molecules by multicomponent domino reactions. This review covers recent trends of last five years (2018–2022) in construction of potentially drug‐like quinoline derivatives. The methods discussed here are preferable over conventional approaches being inexpensive, consuming lesser reaction time, atom economical, saving energy and manpower while avoiding toxic reagents/materials, chemical wastes and are environmental/occupational benign. The contributions covered here involve metallic, metal free strategies and other catalytic pathways including nanoparticles, ionic liquids and photocatalysis which are operationally safe and reliable.
Preparation and Properties of Nanoclay Reinforced High‐Performance Functional Poly(Itaconic Anhydride‐co‐Acrylamide) Nanomaterials
Authors: Kavlak Serap 
Published: October 2022

AbstractIn this work, poly(itaconic anhydride‐co‐acrylamide) copolymer was synthesized by free radical solution copolymerization and poly(itaconic anhydride‐co‐acrylamide)/nanoclay nanocomposites were prepared by in situ interlamellar copolymerization with three different loading of nanoclay. Intercalation and formation of nanostructures were clarified by spectroscopic techniques. The interaction/compatibility between nanoclay and the copolymer was verified by following the characteristic bands of nanoclay and functional groups in the ATR‐FTIR spectra. The increase in d‐spacing between silicate layers in nanocomposites was determined from XRD analysis. The thermal and viscoelastic properties of nanomaterials and the effect of simultaneous addition of nanofiller were evaluated by thermogravimetric and dynamic mechanical analysis. It was observed that nanocomposites reinforced with nanoclay had higher thermal stability than pristine poly(itaconic anhydride‐co‐acrylamide) and thermal stability increased proportionally with amount of nanoclay loaded. The improvement effect of the incorporated nanoclay on the storage modulus was observed at higher temperature values for the nanocomposite loaded with 4 % nanoclay.
Effect of TBP on the Coordination Process of Eu(III) with T2EHDGA: A Luminescence Spectroscopy Investigation
Authors: Rout Alok , Kumar Satendra , Ramanathan Nagarajan 
Published: October 2022

AbstractIn this report, we explore the precise responsibility of a phase modifier along with the prime ligand in the coordination process of Ln(III) ions using luminescence spectroscopic technique by taking Eu(III) as the probeing metal ion. A well accepted diglyoclamide (DGA) ligand: N,N,N’,N’‐ tetra(ethylhexyl)diglycolamide(T2EHDGA) was used as the prime extractant along with tri‐n‐butylphosphate (TBP) as the phase modifier. Meticulous investigations on Eu(III) complexation with T2EHDGA‐TBP binary mixture was pursued by employing luminescence spectroscopy with the systematic variation of the concentration of TBP in the ligating phase and initial concentration of Eu(III) in the feed phase. The dominancy of the LMCT band over that of the metal centered band signifies the structural difference in the ligands used in the study. The presence of TBP in the organic phase enhances the intensity of 5D0→7F2 and 5D0→7F0 transition. The excitation and emission patterns of the Eu(III)‐solvate species formed in the organic phase both in unirraditaed and irradiated conditions were found to be entirely different, which effectively corroborates the efficacy of the extracting phase. The asymmetry ratio (AR) and the life time data at each experimental conditions were ascertained to realize the coordination behavior of the Eu(III) complex in the organic phase.

Published: October 2022

AbstractWe report the implementation of the ligand‐to‐metal charge transfer (LMCT) in organic semiconductors for improved full visible‐light photocatalysis and understanding of the effects of Pd−N weak coordination of a single‐atomic Pd(II) embedded 2D g‐C3N4 (Pd1/UTCN) homogeneous catalyst analogues on the formation of open metal sites and LMCT induced full‐visible‐light photocatalytic performance. LMCT between Pd(II) and g‐C3N4 allows for wide‐range visible light harvesting and promoting the transport of photogenerated charge of carbon nitride from excitation site to active site. Compared to the porphyrin palladium complex with strong Pd−N coordination, the reversible coordination dissociation of Pd−N of Pd1/UTCN allows for the formation of open active sites photocatalysis, which enables the efficient adsorption, activation, and conversion of substrates. The adsorption of the substrate can promote LMCT between Pd(II) and heptanazine ligands. As a result, Pd1/UTCN exhibited LMCT‐induced efficient full‐visible‐light photocatalytic activity of Suzuki reaction with high selectivity without additional phosphorus ligands.

Published: October 2022

AbstractDue to the wide applications of the Reactive Black B (RB−B) in textile industries, it is largely present within the aqueous environment which is a serious environmental threat. Previous studies were unsuccessful to completely remove the color of RB−B from the contaminated environment. In this work, the decolorization of aqueous solutions with RB−B was performed by Potassium bromate. It was found to be a promising oxidizing agent for chemical degradation of organic pollutant. The decolorization and degradation of Reactive Black B by potassium bromate in an aqueous acidic medium was carried out at 591 nm spectrophotometrically at laboratory scale. The reaction was studied under pseudo order conditions having concentration of BrO3− in excess than dye. Under constant conditions, the reaction was found to be first order with respect to both oxidant and reductant. The kinetic salt effect of added salt for the determination of reactive species in the rate‐determining step showed that the rate of reaction is directly related to the increasing concentration of salt, suggesting that two same charged species are involved in the rate‐determining step. Activation parameters were also calculated for the reaction. The highest decolorization percentage of RB−B (99 %) was obtained showing almost complete removal of color of dye from aqueous medium. The proposed degradation of RB−B with bromate was confirmed by qualitative and analytical tests (TDS, EC, UV‐Visible and FTIR spectroscopy).

AbstractIn this study, several metal(II) complexes (Fe, Co, Zn, and Ru) of an azo dye ligand (ADL) that, apart from pyrazole ring (PR), include anisole having (−OCH3) group at the m‐substitue of the phenyl (L: (E)‐4‐((3‐methoxyphenyl)diazenyl)‐3‐methyl‐1H‐pyrazol‐5‐amine) were prepared, characterized, and the biological activity studies were carried out. The structures of complexes were identified by elemental analysis, FTIR, UV‐vis, mass spectra (Fe(II) and Co(II)), 1H‐13C NMR spectra, and TGA‐DTA. The azo ligand and its metal complexes were evaluated for their biological properties according to the enzyme inhibitory activities. The lowest Ki values of Co(II) complex against all three GST (19.48±2.17 μM), AChE (22.14±3.74 μM), and BChE (26.39±3.19 μM) enzymes were verified as the most effective enzyme inhibition. The biological activity results suggest that the obtained complexes have good potentials to be used in further analyses to explore new pharmaceutical agents.

Published: October 2022

AbstractEleven new proteolysis targeting chimeras (PROTACs) based on promiscuous kinase inhibitor Sunitinib were designed, synthesized, and assessed for their anticancer activity against four human cancer cell lines A498, K562, HL‐60 and MCF‐7. Two known compounds were also prepared and used as control samples. The CCK‐8 assay results showed that a new PROTAC with a 1,4‐diaminobutane linker (PROTAC 10) exhibited significant antiproliferative activity against A498 (IC50=0.11 ± 0.01 μM) and K562 (IC50=0.59 ± 0.21 μM) cell lines. Western blot analysis showed that in addition to the previously reported G1 to S phase transition 1 (GSPT1), PROTAC 10 also reduced the protein level of fms‐like tyrosine kinase 3 (FLT3) and proto‐oncogene tyrosine protein kinase Src (SRC) in A498 cells. Moreover, PROTAC 10 regulated the protein levels of GSPT1 and SRC in a dose‐ and time‐dependent manner and induced degradation of GSPT1 in a ubiquitin‐proteasome‐dependent manner in K562 cells.

AbstractThe Dalbergia sissoo leaves traditionally have medicinal values and are well known for current research on osteoporosis and bone health. The present research aims to develop and validate a simple, sensitive, and comprehensive analytical method to standardize Dalbergia sissoo leaves. An ultra‐high performance liquid chromatography method was developed for seven isoflavone glycosides, and isoflavone's identification, including bioactive caviunin and biochanin‐A based glycosides with genistein, pratensein, biochanin‐A, and biochanin‐A‐7‐O‐glucoside for simultaneous quantification in Dalbergia sissoo leaves. Also, a novel high‐performance thin‐layer chromatography‐based method has been developed for isoflavone glycosides as a visual quality control tool for Dalbergia sissoo. Further, seven isoflavonoids were also characterized using mass spectrometry in sample matrices. A qualitative high‐performance thin‐layer chromatography‐based method was found helpful in identifying four major isoflavone glycosides in leaves. The performance of the method and the validation data showed the ultra‐high performance liquid chromatography method was precise (relative standard deviation < 5.0%), accurate (recoveries 80%–110%), robust (relative standard deviation < 5.0%), and linear (r2 > 0.99) for quantification. This well‐separated novel and rapid determination of Dalbergia sissoo compounds in leaves will be helpful in the standardization of the quality assessment tool for Dalbergia sissoo.

AbstractIn 1965, R. B. Woodward and Roald Hoffmann published five communications that formed the basis of the Principle of Conservation of Orbital Symmetry which explained mechanisms of all pericyclic reactions and predicted the allowedness and forbiddeness of such reactions, whether thermal or photochemical. A brief biographical discussion of Hoffmann up to May 1964 is explains why Hoffmann was the ideal individual to participate in the collaboration with Woodward. Why May 1964? Because it was then that the Woodward‐Hoffmann collaboration began.

AbstractThis study aimed to explore whether vitamin B complex (folic acid, B6, and B12) could avert DNA methylation changes associated with inflammation induced by acute PM2.5 exposure. Sprague‐Dawley rats were administered by gavage with different concentrations of vitamin B complex once a day for 28 days, and then by intratracheal instillation with saline or PM2.5 once every 2 days for three times. Vitamin B continued to be taken during the PM2.5 exposure. Rats were sacrificed 24 h after the last exposure. The results showed that vitamin B complex could block the pathological changes and injury in lungs induced by PM2.5. Meanwhile, vitamin B complex could prevent the abnormal DNA methylation of IL‐4 and IFN‐γ to antagonize the imbalance of IL‐4/IFN‐γ associated with inflammation. It was further found that vitamin B complex could regulate DNA methyltransferases (DNMTs) and increase the S‐adenosylmethionine (SAM)/S‐Adenosyl‐L‐homocysteine (SAH) ratio to reverse the hypomethylation of genomic DNA and the abnormal DNA methylation of IL‐4 and IFN‐γ. In conclusion, vitamin B complex has a protective effect on acute lung injury by attenuating abnormal DNA methylation induced by PM2.5 in rats. This study may provide a new insight into the physiological function of vitamin B to prevent the health effects induced by PM2.5.
Does the evidence base on social determinants of health cross disciplinary boundaries? A review of reviews
Authors: Johnson Sydney , Frech Adrianne , Edwards Bob , Tumin Dmitry 
Published: October 2022

AbstractSocial determinants of health (SDH) have emerged as a major area of emphasis in medicine over the last 30 years. While increasing interest in SDH has led to a proliferation of literature on this topic, it is unclear whether the medical evidence base on SDH has assimilated contributions from other disciplines. We analyzed interdisciplinary contributions to the medical evidence base on SDH, using a bibliographic analysis of highly cited literature reviews. Medical review articles from 1990 to 2020 were queried using the Scopus database, with a keyword search in the title and abstract for “social determinants of health.” The top 100 most highly cited articles were sampled for inclusion, and references in each review were screened to identify journal articles published in other disciplines. An initial Scopus search identified 502 eligible reviews. After reviewing the top 100 most highly cited articles, 40 articles published between 2000 and 2017 met our inclusion criteria. and received between 33 and 940 citations. These reviews included references to a median of 41 journal articles (interquartile range [IQR]: 25, 67), of which a median of 11 was from public health journals (IQR: 6, 18) and 4 were from other social science fields (IQR: 1, 11). On multivariable analysis, more recent reviews incorporated more sources from public health but not from other social science fields. Relevant SDH scholarship from sociology and related fields is not being integrated into the evidence base directed at clinician audiences and may be underutilized in shaping policy and practice in these areas.
Ubiquitous Surveillance and Data Selves
Authors: Frow John 
Published: October 2022

AbstractAre we made up entirely and without residue of the data that defines us, or is there a disjunction between our data shadows and our embodied selves? How do we come to recognize ourselves, our selves, in the pronouns that interpellate us online, and what is it exactly that we recognize? What does it mean to occupy the semantic and positional space of the pronoun ‘you’? And is there a continuity or a discontinuity between the systems of surveillance and data aggregation that address us and the systems that don’t? The markers of identity generated by such systems work by both individuating and classifying us; this chapter seeks to think about the range of possible relations between that generality and that particularity.
Deciphering the maximal transcendentality principle via bootstrap
Authors: Guo Yuanhong , Jin Qing jun , Wang Lei , Yang Gang 
Published: October 2022

Abstract
We prove the principle of maximal transcendentality for a class of form factors, including the general two-loop minimal form factors, the two-loop three-point form factor of tr(F2), and the two-loop four-point form factor of tr(F3). Our proof is based on a recently developed bootstrap method using the representation of master integral expansions, together with some unitarity cuts that are universal in general gauge theories. The maximally transcendental parts of the two-loop four-gluon form factor of tr(F3) are obtained for the first time in both planar $$ \mathcal{N} $$
N
= 4 SYM and pure YM theories. This form factor can be understood as the Higgs-plus-four-gluon amplitudes involving a dimension-seven operator in the Higgs effective theory. In this case, we find that the maximally transcendental part of the $$ \mathcal{N} $$
N
= 4 SYM result is different from that of pure YM, and the discrepancy is due to the gluino-loop contributions in $$ \mathcal{N} $$
N
= 4 SYM. In contrast, the scalar-loop contributions have no maximally transcendental parts. Thus, the maximal transcendentality principle still holds for the form factor results in $$ \mathcal{N} $$
N
= 4 SYM and QCD, after a proper identification of the fundamental quarks and adjoint gluinos as nf→ 4Nc. This seems to be the first example of the maximally transcendental principle that involves fermion-loop contributions. As another intriguing observation, we find that the four-point form factor of the half-BPS tr(ϕ3) operator is precisely a building block in the form factor of tr(F3).
