TL;DR: The history of amaranth and recent advances in genomic tools are reviewed and a concrete perspective how novel breeding techniques can be implemented into breeding programs are given to improve the nutritional quality and climate resilience of future cropping systems is given.
Abstract: Grain amaranth is an underutilized crop with high nutritional quality from the Americas. Emerging genomic and biotechnological tools are becoming available that allow the integration of novel breeding techniques for rapid improvement of amaranth and other underutilized crops. Out of thousands of edible plants, only three cereals—maize, wheat and rice—are the major food sources for a majority of people worldwide. While these crops provide high amounts of calories, they are low in protein and other essential nutrients. The dependence on only few crops, with often narrow genetic basis, leads to a high vulnerability of modern cropping systems to the predicted climate change and accompanying weather extremes. Broadening our food sources through the integration of so-called orphan crops can help to mitigate the effects of environmental change and improve qualitative food security. Thousands of traditional crops are known, but have received little attention in the last century and breeding efforts were limited. Amaranth is such an underutilized pseudocereal that is of particular interest because of its balanced amino acid and micronutrient profiles. Additionally, the C4 photosynthetic pathway and ability to withstand environmental stress make the crop a suitable choice for future agricultural systems. Despite the potential of amaranth, efforts of genetic improvement lag considerably behind those of major crops. The progress in novel breeding methods and molecular techniques developed in model plants and major crops allow a rapid improvement of underutilized crops. Here, we review the history of amaranth and recent advances in genomic tools and give a concrete perspective how novel breeding techniques can be implemented into breeding programs. Our perspectives are transferable to many underutilized crops. The implementation of these could improve the nutritional quality and climate resilience of future cropping systems.

TL;DR: A thorough study of the transport properties of the normal and superconducting states of black phosphorus (BP) under magnetic field and high pressure with a large-volume apparatus that provides hydrostatic pressure to induce transitions from the layered A17 phase to the stacked A7 phase and to the cubic phase of BP.
Abstract: We report a thorough study of the transport properties of the normal and superconducting states of black phosphorus (BP) under magnetic field and high pressure with a large-volume apparatus that provides hydrostatic pressure to induce transitions from the layered A17 phase to the layered A7 phase and to the cubic phase of BP Quantum oscillations can be observed at P ≥ 1 GPa in both resistivity and Hall voltage, and their evolutions with pressure in the A17 phase imply a continuous enlargement of Fermi surface A significantly large magnetoresistance (MR) at low temperatures is observed in the A7 phase that becomes superconducting below a superconducting transition temperature T c ∼ 6–13 K T c increases continuously with pressure on crossing the A7 to the cubic phase boundary The strong MR effect can be fit by a modified Kohler’s rule A correlation between T c and fitting parameters suggests that phonon-mediated interactions play dominant roles in driving the Cooper pairing, which is further supported by our density functional theory (DFT) calculations The change of effective carrier mobility in the A17 phase under pressure derived from the MR effect is consistent with that obtained from the temperature dependence of the quantum oscillations In situ single-crystal diffraction under high pressure indicates a total structural reconstruction instead of simple stretching of the A17 phase layers in the A17-to-A7-phase transition This finding helps us to interpret transport properties on crossing the phase transition under high pressure

TL;DR: 1,2,3-triazole and sulfonate analogues of natural bioactive precursors were designed and synthesized and 5e and 5u bearing carboxylic acid functionality emerged as potent antibacterial agents against S. pneumoniae and E. coli strains and significantly inhibited biofilm formation.
Abstract: Despite the vast availability of antibiotics, bacterial infections remain a leading cause of death worldwide. In an effort to enhance the armamentarium against resistant bacterial strains, 1,2,3-triazole (5a-x) and sulfonate (7a-j) analogues of natural bioactive precursors were designed and synthesized. Preliminary screening against two Gram-positive (Streptococcus pneumoniae and Enterococcus faecalis) and four Gram-negative bacterial strains (Pseudomonas aeruginosa, Salmonella enterica, Klebsiella pneumoniae, and Escherichia coli) was performed to assess the potency of these analogues as antibacterial agents. Among all triazole analogues, 5e (derived from carvacrol) and 5u (derived from 2-hydroxy 1,4-naphthoquinone) bearing carboxylic acid functionality emerged as potent antibacterial agents against S. pneumoniae (IC50: 62.53 and 39.33 μg/mL), E. faecalis (IC50: 36.66 and 61.09 μg/mL), and E. coli (IC50: 15.28 and 22.57 μg/mL). Furthermore, 5e and 5u also demonstrated moderate efficacy against multidrug-resistant E. coli strains and were therefore selected for further biological studies. Compound 5e in combination with ciprofloxacin displayed a synergistic effect on multidrug-resistant E. coli MRA11 and MRC17 strains, whereas compound 5u was selective against E. coli MRA11 strain. Growth kinetic studies on S. pneumoniae and E. coli treated with 5e and 5u showed an extended lag phase. 5e and 5u did not show significant cytotoxicity up to 100 μg/mL concentration on human embryonic kidney (HEK293) cells. Transmission electron microscopic (TEM) analysis of bacterial cells (S. pneumoniae and E. coli) exposed to 5e and 5u clearly showed morphological changes and damaged cell walls. Moreover, these compounds also significantly inhibited biofilm formation in S. pneumoniae and E. coli strains, which was visualized by scanning electron microscopic (SEM) analysis. Treatment of larvae of Galleria mellonella (an in vivo model for antimicrobial studies) with 5e and 5u did not cause an alteration in the hemocyte density, thereby indicating lack of an immune response, and were nontoxic up to a concentration of 2.5 mg/mL.

TL;DR: In this paper, an extensive study of 72 archival Chandra light curves of the high-frequency-peaked type blazar Mrk 421, the first strong extragalactic object to be detected at TeV energies, is presented.
Abstract: We present an extensive study of 72 archival Chandra light curves of the high-frequency-peaked type blazar Mrk 421, the first strong extragalactic object to be detected at TeV energies. Between 2000 and 2015 Mrk 421 often displayed intraday variability in the 0.3-10.0 keV energy range, as quantified through fractional variability amplitudes that range up to 21.3 per cent. A variability duty cycle of ~84 per cent is present in these data. Variability timescales, with values ranging from 5.5 to 30.5 ks, appear to be present in seven of these observations. Discrete correlation function analyses show positive correlations between the soft (0.3-2.0 keV) and hard (2.0-10.0 keV) X-ray energy bands with zero time lags, indicating that very similar electron populations are responsible for the emission of all the X-rays observed by Chandra. The hardness ratios of this X-ray emission indicate a general "harder-when-brighter" trend in the spectral behaviour of Mrk 421. Spectral index-flux plots provide model independent indications of the spectral evolution of the source and information on the X-ray emission mechanisms. Brief discussions of theoretical models that are consistent with these observations are given.

TL;DR: In this paper, CdS-TiO2 composite thick film was used for propanol sensing and the results showed that 2.75 times more than L.P. and 1.94 time of ethanol was achieved by 2.
Abstract: Cadmium Sulphide (CdS) doped Titanium dioxide (TiO2) thick film sensor was produced on alumina substrate and their propanol sensing behaviour were investigated. Undoped TiO2 and 2wt% CdS-TiO2 thick film are fabricated on alumina substrate. Sensing properties such as, sensitivity and selectivity measurement are carried out in the range 0- 5000 ppm at room temperature. The results showed that, 2wt% CdS-TiO2 sample gives higher response (60%) for propanol against L.P.G. and ethanol. The response of propanol is 3.75 times more than L.P.G. and 1.94 time of Ethanol. 2wt% CdS-TiO2 sample are more (56.08 %) selective for propanol over L.P.G. and Ethanol. The result obtained indicated that CdS-TiO2 composite thick film may used for propanol sensing.

TL;DR: In this paper, polypyrrole and its silver nanocomposite were electrochemically synthesized from aqueous solutions containing pyrrole, potassium chloride (KCl), and an anionic surfactant sodium dodecyl sulphate (NaDS) and compact and dendritic patterns were observed depending on experimental conditions.
Abstract: Polypyrrole and its silver nanocomposite were electrochemically synthesized from aqueous solutions containing pyrrole, potassium chloride (KCl) (system A); pyrrole, KCl, and an anionic surfactant sodium dodecyl sulphate (NaDS) (system B); and pyrrole, silver nitrate, NaDS (system C). Compact and dendritic patterns were observed depending on experimental conditions. The aggregates were characterized by powder X-ray diffraction, energy-dispersive X-ray spectroscopy, scanning electron microscopy, high resolution transmission electron microscopic (HRTEM), and thermal studies (TG/DTG). HRTEM studies indicate that the particle size of PPy-Ag nanocomposite is ∼30 nm. TG studies revealed that systems B and C, have different thermal behavior. Potassium ion selective electrodes were constructed using systems A, B, and C. The electrode prepared with PPy-Ag nanocomposite showed nernstian behavior with maximum slope of 57 mV. NH4+ ion-selective electrode was also constructed for this system based on nonactin-impregnated PVC matrix membrane. Urease enzyme was immobilized at the surface of as made NH4+ ion-selective electrode to develop urea biosensor showing good detection limit. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

TL;DR: The interaction of SPIONs with amyloid beta-42 (Aβ42), a biomarker for AD progression, has been shown and may lead to better understanding, which is required to target the metabolism of Aß42 peptide, a pivotal player in this pathology.
Abstract: Alzheimer’s disease (AD) pathogenesis leads to the appearance of senile plaques due to the production and deposition of the β-amyloid peptide (Aβ). Superparamagnetic iron oxide nanoparticles (SPIONs) have potential role in the detection and imaging of Aβ plaques in AD. SPIONs have shown appropriate potential in the diagnosis and treatment of AD. In the present study, the pharmacokinetics of SPIONs and its effect in the biochemical pathway of AD were analyzed using collected information. During analysis, the interaction of SPIONs with amyloid beta-42 (Aβ42), a biomarker for AD progression, has been shown. Nodes represent the entities and edges represent the relation (interactions) of one node to another node. Aβ42 and their interaction with other entities making up biochemical network are involved in AD mechanism in presence of SPION. The kinetic simulation was done to investigate pharmacokinetics of SPIONs for AD, where concentration was assigned of nanoparticles and other entities were applied as a kinetic irreversible simple Michaelis–Menten or mass action kinetics. Simulation was done in presence and absence of SPIONs to investigate pharmacokinetic effect in AD and explore the mechanism of Aβ42 in presence of SPIONs. This study may lead to better understanding, which is required to target the metabolism of As42 peptide, a pivotal player in this pathology.

TL;DR: In this article, the basics of the science of omics along with relevant tools and diverse applications are highlighted along with the relevant applications and tools and relevant tools for the manipulation of life processes for the benefit of humankind.
Abstract: The science of “omics” reflects the innovations in diverse technologies leading to studies of life processes in totality. With the initial emergence of genomics, proteomics, and metabolomics associated with the comprehensive studies of genes, proteins, and metabolites of an organism, respectively, there has been a substantial growth in other branches of omics such as lipidomics, cytomics, phenomics, and transcriptomics. The omics-driven science has a potential application in crop-improvement program, human health sector, environmental sector, and industrial sector. The recent developments in genome sequencing have further expanded the scope of the omics technologies for elucidating the complexity of life processes and understanding the gene expression and regulation in diverse systems. The concept of bioengineering is more relevant to the human health and is often referred to as biomedical engineering. In general, it covers tools and technologies associated with the manipulation of life processes for the benefit of the humankind. In biological system, the central dogma of molecular biology, i.e., replication, transcription, and translation, is the main center of attraction for manipulation using appropriate tools of omics. This chapter highlights the basics of science of omics along with relevant tools and diverse applications.

TL;DR: A proposed common BPR framework and methodology for organisations has developed based on the design of recent BPR frameworks and methodologies identified in the literature, and the expected benefits of BPR are outlined.
Abstract: Business process reengineering (BPR) has become a most popular change management approach for radical redesign and improvement of business process. It promotes companies to do things effectively in order to achieve overall quality. Unfortunately, it has been estimated that more than 70% of BPR implementations have failed to achieve expected results due to lake of suitable framework and methodology. Therefore, the author tried to assess the available some different BPR framework and methodology aiming to develop a suitable framework and methodology as well as to fill the literature gap. The other aims of this study are to study the BPR factors that may influence the performance and to explore the implementation level of BPR in Indian manufacturing organisations. In this paper, a proposed common BPR framework and methodology for organisations has developed based on the design of recent BPR frameworks and methodologies identified in the literature. The major component factors of BPR for the manufacturing organisations have been shown in figure. This paper also presents the success and failure factor that affect BPR projects. Finally, the conclusion places the findings of this study and outlines the expected benefits of BPR.

Abstract: The present study deals with the spherically symmetric distributions of dust dissipative fluids with a central vacuum cavity, evolving under the condition of vanishing of expansion scalar. The work is based on two aspects—on the one hand the description of model in terms of structures scalars emerging in the orthogonal splitting of Riemann tensor. Secondly, to obtain the solutions of dynamical equations under some special cases and assumption on implicit function of variables. The solutions here discussed, model the evolution of the vacuum cavity of fluid distribution, thereby showing the potential of expansion free motion.

TL;DR: In this paper, the phase change studies in Se85In15−xZnx thin films at various annealing temperatures were described on the basis of structural relaxation and changes in defect states and density of localized states during amorphous to crystalline phase transformation.
Abstract: This research work describes the phase change studies in Se85In15−xZnx thin films at various annealing temperatures. Glassy samples of Se85In15−xZnx were synthesized by the melt quenching method and thin films of thickness 400 nm were prepared by the vacuum evaporation technique on a glass/Si wafer substrate. The glass transition temperature (Tg) and the on-set crystallization temperature (Tc) of the prepared alloys were evaluated by non-isothermal differential scanning calorimetry studies. Thin films were annealed at three temperatures 330 K, 340 K, and 350 K (which are in between Tg and Tc of the synthesized samples) in a vacuum furnace for 2 h. High resolution X-ray diffraction studies demonstrate that the as-prepared films are amorphous in nature whereas the annealed films are of crystalline/polycrystalline in nature. Field emission scanning electron microscopy studies of thin films (as-deposited and crystallized) confirm the phase transformation in Se85In15−xZnx thin films. Optical band gaps were calculated from the Tauc's extrapolation procedure and were found to be enhanced with the Zn concentration and decrease with the increasing annealing temperature. Various optical parameters were evaluated for as-prepared and annealed Se85In15−xZnx thin films. The changes in optical parameters with annealing temperature were described on the basis of structural relaxation as well as changes in defect states and density of localized states during amorphous to crystalline phase transformation in Se85In15−xZnx thin films.This research work describes the phase change studies in Se85In15−xZnx thin films at various annealing temperatures.

TL;DR: It is demonstrated that BaA and 4-OHBaA exert multiple detrimental effects on the development of H. pulcherrimus through effects on larval skeletogenesis via VEGF signaling and the expression of Endo16 mRNA, an endodermal marker, decreased, suggesting that these chemicals affectendodermal function together with skeletogenesis.
Abstract: Polycyclic aromatic hydrocarbons including benz[a]anthracene (BaA) are priority pollutants in the aquatic environment. Our previous study revealed that BaA and its metabolite, 4-monohydroxylated BaA (4-OHBaA) inhibit larval skeletogenesis in the sea urchin Hemicentrotus pulcherrimus. Here we report studies to elucidate the target of skeletogenesis inhibition elicited by BaA and 4-OHBaA. First, we performed an in vitro experiment using isolated micromeres which give rise to the larval skeletogenic mesenchyme. However, skeletogenesis was not repressed by BaA and 4-OHBaA, implying that these chemicals indirectly influence on the formation of larval skeleton. Next, we analyzed their influence in vivo using embryos. Vascular endothelial growth factor (VEGF) that is expressed in the ectoderm and induces spicule formation was inhibited by BaA and 4-OHBaA treatment. These chemicals also suppressed the expression of the heparan sulfate 6-O endosulfatase (Sulf) known as a VEGF signaling modulator. We, therefore, propose that BaA and 4-OHBaA effects on larval skeletogenesis via VEGF signaling. Furthermore, we showed that the expression of Endo16 mRNA, an endodermal marker, decreased after BaA and 4-OHBaA exposure, suggesting that these chemicals affect endodermal function together with skeletogenesis. This study demonstrates that BaA and 4-OHBaA exert multiple detrimental effects on the development of H. pulcherrimus.

TL;DR: In this paper, the authors investigated the relationship between self-esteem and satisfaction with life in current college students and found significantly correlated in male, female, urban and general category participants.
Abstract: Self-esteem reflects an individual's perception and evaluation of himself or herself, whereas, life satisfaction involves the individual's evaluation of one's life as a whole including different areas of life such as school, family and friends as well as oneself (Civitci & Civitci, 2009). The aim of the study was to investigate the relationship between self esteem and satisfaction with life in current college students. A total of 200 college students (100 Male & 100 Female) from Veer Bahadur Singh University Jaunpur (U.P.) participated. Rosenberg self-esteem scale (1965) and satisfactions with life scale (Diener et al., 1985) were administered. Self-esteem and satisfaction with life was found significantly correlated in male, female, urban and general category participants. The effect of self-esteem on satisfaction with life was found significant

TL;DR: Results of site-specific selective pressure analysis throw light on the functional diversity of PGs in various plant processes and hence its constitutive nature and are further strengthened by functional divergence analysis which reveals functionally diverse groups in all the four species representing monocots and dicots.
Abstract: The polygalacturonases (PG) is one of the important members of pectin-degrading glycoside hydrolases of the family GH28. In plants, PG represents multigene families associated with diverse processes. In the present study, an attempt has been made to investigate the diversity of PG genes among monocots and dicots with respect to phylogeny, gene duplication and subcellular localization to get an insight into the evolutionary and functional attributes. The genome-wide assessment of Medicago truncatula, Vitis vinifera Sorghum bicolor, and Oryza sativa L. ssp. japonica genomes revealed 53, 49, 38 and 35 PG-like (PGL) genes, respectively. The predominance of glyco_hydro_28 domain, hydrophilic nature and genes with multiple introns were uniformly observed. The subcellular localization showed the presence of signal sequences targeting the secretory pathways. The phylogenetic tree constructed marked uniformity with three distinct clusters for each plant irrespective of the variability in the genome sizes. The site-specific selection pressure analysis based on K a/K s values showed predominance of purifying selection pressures among different groups identified in these plants. The functional divergence analysis revealed significant site-specific selective constraints. Results of site-specific selective pressure analysis throw light on the functional diversity of PGs in various plant processes and hence its constitutive nature. These findings are further strengthened by functional divergence analysis which reveals functionally diverse groups in all the four species representing monocots and dicots. The outcome of the present work could be utilized for deciphering the novel functions of PGs in plants.

TL;DR: In this paper, the smallest alkali metal (Li) and halogen (F) atoms were encapsulated in the C60 cage, and comparative quantum chemical calculations (QCCs) were performed on their various properties using a density functional theory approach.
Abstract: Fullerene (C60) is a stable prototype system for a special class of nanomaterials. In this work, the smallest alkali metal (Li) and halogen (F) atoms were encapsulated in the C60 cage, and comparative quantum chemical calculations (QCCs) were performed on their various properties using a density functional theory approach. It was noted that the off-centre distance of Li is higher than that of F. The QCCs of the charge transfer to and from C60 were also analysed. Although charge transfer to and from the C60 cage takes place in both cases, Li@C60 becomes more polar than F@C60, suggesting a better electron-accepting nature of C60 than electron-donating behaviour. This fact is consistent with the natural bond orbital (NBO) charge on the trapped atoms and the dipole moment as well as the binding energy values of the encapsulated C60. Although the encapsulation of both atoms reduces the frontier orbital energy gap, the frontier orbital gap of Li@C60 is smaller than that of F@C60. More interestingly, the depression in the polarizability of Li@C60 is significantly large relative to that of F@C60. These findings also support the tendency of C60 to act as electron acceptor. This study provides some insights into the fundamental properties of C60 and should be helpful in designing new endofullerene complexes for a variety of applications.
