Abstract:

Plants synthesize a diversity of volatile molecules that are important for reproduction and defense, serve as practical products for humans, and influence atmospheric chemistry and climate. Despite progress in deciphering plant volatile biosynthesis, their release from the cell has been poorly understood. The default assumption has been that volatiles passively diffuse out of cells. By characterization of aPetunia hybridaadenosine triphosphate–binding cassette (ABC) transporter, PhABCG1, we demonstrate that passage of volatiles across the plasma membrane relies on active transport.PhABCG1down-regulation by RNA interference results in decreased emission of volatiles, which accumulate to toxic levels in the plasma membrane. This study provides direct proof of a biologically mediated mechanism of volatile emission.

Abstract:

Odorant-binding proteins (OBPs) play a key role in the olfactory system and are essential for mating and oviposition host selection. Tirathaba rufivena, a serious lepidopterous insect pest of the palm area in recent years, has threatened cultivations of Areca catechu in Hainan. Female-biased odorant-binding protein 4 of T. rufivena (TrufOBP4) expression was hypothesized to participate in the process of oviposition host recognition and localization. In this study, we cloned and analyzed the cDNA sequence of TrufOBP4. The predicted mature protein TrufOBP4 is a small, soluble, secretory protein and belongs to a classic OBP subfamily. Fluorescence binding assay results showed that TrufOBP4 had high binding abilities with the host plant volatiles, octyl methoxycinnamate, dibutyl phthalate, myristic acid and palmitic acid. These four components tend to dock in the same binding pocket based on the molecular docking result. The interactions and contributions of key amino acid residues were also characterized. This research provides evidence that TrufOBP4 might participate in the chemoreception of volatile compounds from inflorescences of A. catechu and can contribute to the integrated management of T. rufivena.

Abstract:

Background Volatile general anesthetics (VAs) have a number of synaptic actions, one of which is to inhibit excitatory neurotransmitter release; however, no presynaptic VA binding proteins have been identified. Genetic data in Caenorhabditis elegans have led to the hypothesis that a protein that interacts with the presynaptic protein syntaxin 1A is a VA target. Motivated by this hypothesis, the authors measured the ability of syntaxin 1A and proteins that interact with syntaxin to bind to halothane and isoflurane. Methods Recombinant rat syntaxin 1A, SNAP-25B, VAMP2, and the ternary SNARE complex that they form were tested. Binding of VAs to these proteins was detected by F-nuclear magnetic resonance relaxation measurements. Structural alterations in the proteins were examined by circular dichroism and ability to form complexes. Results Volatile anesthetics did not bind to VAMP2. At concentrations in the clinical range, VAs did bind to SNAP-25B; however, binding was detected only in preparations containing SNAP-25B homomultimers. VAs also bound at clinical concentrations to both syntaxin and the SNARE complex. Addition of an N-terminal His6 tag to syntaxin abolished its ability to bind VAs despite normal secondary structure and ability to form SNARE complexes; thrombin cleavage of the tag restored VA binding. Thus, the VA binding site(s) has structural requirements and is not simply any alpha-helical bundle. VAs at supraclinical concentrations produced an increase in helicity of the SNARE complex; otherwise, VA binding produced no gross alteration in the stability or secondary structure of the SNARE complex. Conclusion SNARE proteins are potential synaptic targets of volatile anesthetics.

Abstract:

Odorant binding proteins play a key role in the olfactory system and are involved in the odor perception and discrimination of insects. To investigate the potential physiological functions of SaveOBP9 in Sitobion avenae, fluorescence ligand binding experiments, molecular docking, RNA interference, and behavioral tests were performed. Fluorescence binding assay results showed that SaveOBP9 had broad and high (Ki < 10 μM) binding abilities with most of the wheat volatiles, but was more obvious at pH 7.4 than pH 5.0. The binding sites of SaveOBP9 to the volatiles were predicted well by three-dimensional docking structure modeling and molecular docking. Moreover, S. avenae showed a strong behavioral response with the four compounds of wheat. The reduction in mRNA transcript levels after the RNA interference significantly reduced the expression level of SaveOBP9 and induced the non-significant response of S. avenae to the tetradecane, octanal, decanal, and hexadecane. This study provides evidence that SaveOBP9 might be involved in the chemoreception of wheat volatile organic compounds and can successfully contribute in the integrated management programs of S. avenae.

Abstract:

Flavour is widely accepted as a major determinant of consumer satisfaction, so factors that influence flavour quality are of great interest to both food scientists and the manufacturing industry globally. Volatile organic compounds (VOC) play an important role in characterising the unique flavour profile of foods. However non-volatile matrix solutes are capable of selectively binding these compounds and modifying their availability for perception during consumption. The impact of carbohydrates and lipids has been extensively studied which has led to a comprehensive understanding of the principles governing their interaction with flavour volatiles. Proteins, in comparison, remain poorly understood. This is due mainly to their structural diversity and resulting range of available binding mechanisms which can change in response to environmental conditions such as those encountered during food processing. Myofibrillar proteins are compositionally significant components of skeletal muscle tissue and play a critical role in defining the textural properties of processed meat products including burgers and sausages. To determine their influence on flavour, a series of model solutions were analysed and partition coefficients Kg-m calculated to enable changes in compound volatility to be measured. Eleven different flavour volatiles were evaluated, including a number of plant derived bioactive compounds not previously considered in binding studies. Partition coefficients were measured using static headspace-gas chromatography (SH-GC) methods partnered with indirect phase ratio variation (PRV) techniques. The retention effect of myofibrillar proteins was quantified by reporting the percentage change in Kg-m following the introduction of protein extract into the system. Myofibrillar proteins were obtained from a series of extractions of pork loin fillet with sodium phosphate buffer. The process yielded 58.6 mg/g of muscle which accounted for an approximate recovery rate of 60% of total available proteins. Subsequent instrumental analysis confirmed that at 35°C, a 2 mg/mL protein extract was capable of binding all volatile compounds, to various degrees, reducing their volatility, or headspace concentration, and therefore the availability of each compound for sensory perception. The greatest effect was recorded for isomers citral and neral, with 55.9% and 59.1% retention reported respectively, followed by ethyl hexanote which gave 36.7% retention. Thymol and carvacrol followed closely, with 28.6% and 33.7% retention respectively. Data collected throughout the study strongly indicates that myofibrillar proteins interact predominantly via weak reversible associations that are enhanced with increasing levels of flavour compound hydrophobicity. Both SH-GC and PRV are commonly utilised in flavour interaction investigations and are known to have areas of limitation that must be considered throughout application. During instrumental method development however, a significant obstacle was encountered which had not been documented previously. After considerable method development, it was concluded that mass spectrometer (MS) detectors are not suitable for use in PRV trials due to the repeated injection of headspace water vapour into the system. This damaged MS components and limited the ionisation of analytes required for their detection.

Abstract:

Bovine ß-lactoglobulin (ß-Lg) has been studied extensively but there is no clear identification of its biological function. Hydrophobic molecules have been observed binding into the hydrophobic calyx of ß-Lg. By comparison with other members of lipocalin family, it is probable that ß-Lg plays a role of transport of ligands, as ligands also bind into the central cavity of lipocalins. The structurally similar MUP is a pheromone-binding protein; therefore, it is possible that ß-Lg may also fulfil a similar role. This study has begun to test this hypothesis by investigating the interactions between bovine ß-Lg and several small volatile molecules (2-sec-4,5-dihydrothiazole, 3-methyl-2-butenal, 3-methyl-2-buten-1-ol and phenylacetic acid). The interactions between the volatile molecules and ß-Lg were studied by both two-dimensional NMR spectroscopy and X-ray crystallographic methods. TOCSY spectra were recorded for ß-Lg and the complex between ß-Lg and the ligands. The observed chemical shifts in the HN-Ha region are sensitive to the proximity of ligands, and hence chemical shift changes on ligand binding provide information on possible binding sites. It appears that several amino acids with hydrophobic sidechains are affected by interaction with volatile molecules at pH 2.0. The X-ray crystallographic study at pH 8.5 showed that the potential ligand, 2-sec-4,5-dihydrothiazole, may have decomposed into a linear 2-methyl-butanol. The refined structure (R=0.281, Rfree=0.354 for reflections to 2.6 Å resolution) reveals that the potential ligand may bind to the central cavity in a manner similar to the binding of 12-bromodecanoic acid to ß-Lg.

Abstract:

The importance of the changes and variability in pharmacology with ageing and the risks these pose in the elderly are emphasized. Detailed descriptions are given of the pharmacokinetic aspects of distribution, initial volume of distribution, and plasma binding; elimination affected by hepatic and renal clearance changes; and effect site variability. The pharmacodynamics changes are then reviewed. Specific anaesthetic agents are then described, covering the induction agents thiopentone, propofol, etomidate, ketamine, and midazolam. The volatile anaesthetics sevoflurane and desflurane, and nitrous oxide are discussed. The opioid analgesics fentanyl, alfentanil, sufentanil, and remifentanil are described followed by the opiate morphine. The much slower onset and offset of muscle relaxants in the elderly is explained, and the differences between steroid and benzylisoquinolinium compounds are described. Finally, the reversal agents, including sugammadex, are reviewed.

Abstract:

This is the dawn of an innovation and knowledge-driven economy, and the volatile business environment is forcing the industries to undergo a paradigm shift. This is causing volatility of business parameters from value creation to value maximization through reduction of value loss., instead of merely focusing on the value creation. This value maximization gels with quality, binding the end outcomes of enterprise, and quality of these end outcomes cumulatively shows the dependability towards the various inputs like man, money, material, machine, and information to innovate and re-innovate and measure continuously. Without saturation and to create value continuously in circular motion for spiral growth in circular economy all dimensions needs to be innovative to gain sustainable competitive advantage (SCA). The chapter is a study of concepts and models to impel the SCA. It analyzes innovation as a measure driver for SCA with various types of risk associated with it in the context of the circular economy.

Abstract:

Employees have other expectations as an extension of what is usually expressly stated in formal, written or legally binding employment contracts. They (employees) develop perceptions about certain obligations which employers should fulfill in response to their contributions. This informal but normal employee expectation is known as the psychological contract. The effective management of the psychological contract in modern organizations has never been more crucial for managers. This is essentially because of the subjective and fluid nature of this concept, differences in personal values, and an accelerated pace of change in the operating environment of organizations. A good employment relationship creates an enabling environment for employees enhancing performance and productivity. It is also the bedrock of job satisfaction, motivation, commitment, citizenship behaviour, and employee retention. These factors are key determinants of organizational success and sustainability. A perceived breach or violation results in negative attitudinal and behavioral responses, whereas a positive psychological contract boosts employees’ morale. In this article, we explore the concept of the psychological contract, its changing nature, and effective management. Insight is given on managing the psychological contract to enhance the commitment, performance, and productivity of employees as well as continued organizational success in a constantly volatile environment.

Abstract:

Abstract The chemical senses—taste and smell—are the oldest animal senses. They are characterized by a multidimensional and diverse stimulus space, consisting of many molecules that cannot be classified along any narrow set of dimensions. In the case of the olfactory system, animals detect low molecular weight volatile chemicals (i.e. odorants) with the help of specialized olfactory sensory neurons that express one or a few ligand-binding odorant receptor proteins. Animals cope with the problem of recognizing an extremely large number of different odorants by programming a very large number of functionally different olfactory neurons. Odours activate these neurons and generate characteristic activity patterns across the neuron population, which are relayed to second-order olfactory neurons. The entire available raw information about the animal’s olfactory environment is present in these patterns; however, olfactory information is further processed before it is relayed to higher-order brain centres. Drosophila melanogaster provides an attractive model organism for studying olfaction, as it allows genetic, molecular, and physiological analyses. In recent years, immense progress has been achieved in understanding the olfactory neuronal circuits that underlie the coding and processing of odours in Drosophila. Here, the chapter reviews our present state of knowledge regarding the anatomical architecture of the fly’s olfactory system as well as giving recent insights into the coding strategies of the different neuronal populations involved.

Abstract:

The transport and fate of chemicals in the environment comprise one of the most pertinent issues in environmental chemistry. Physical and chemical interactions between the chemical of interest (sorbate) and the various components present in soil, water, and sediment (sorbent) can dramatically influence the transport and fate of the chemical. For example, organic material such as humic acids or surfactants, when bound to the surface of soil, sediment, and clay particles, can enhance sorption of chemicals to the particle surface, immobilizing the chemicals and possibly protecting them from degradation. The term “sorption,” as used in this chapter, refers to any physical or chemical association between the sorbate and sorbent. Thus, this definition includes molecular associations ranging from hydrophobic partitioning processes to covalent binding. It has also been observed that sorbents can act as a “buffer system” for the sorbate by taking up the sorbate when it is present at high concentrations and then slowly releasing it back into solution during periods of low or zero sorbate concentration. This type of behavior is important when the environmental presence of the chemical is episodic, such as in seasonal application of pesticides and herbicides. A dramatic example of this is presented by Steinberg et al., who detected the volatile, soil fumigant 1,2-dibromoethane in agricultural topsoils up to 19 years after the last application. On the other hand, soluble organic matter such as dissolved humic and fulvic acids can dramatically increase the apparent solubility of many hydrophobic chemicals in soil and sediment pore water. In this manner, the mobility of the chemical is increased. Thus, the nature and presence of organic material can strongly influence the transport properties of many chemicals in the environment. It is well known that sorption processes are a function of numerous parameters: the chemical characteristics of the sorbate (e.g., hydrophobicity, polarity), and the identity and chemical characteristics of the mineral phase and its organic coating. Other parameters important to sorption processes are the porosity of the sorbent particles, the presence of dissolved organic matter, and the solution pH and ionic strength.

Abstract:

Quartz crystal microbalance (QCM) device is a highly sensitive mass sensor (sensitivity: 0.5 ng/cm2) with a wide range of applications including biosensing, thin film deposition, surface chemistry, volatile organic compounds (VOC) and gaseous analytes detection. A recent study shows that several orders of magnitude improvement in sensitivity can be achieved by attaching microscale Polymethyl methacrylate (PMMA) pillars onto the surface of the QCM (QCM-P) to form a two-degree of freedom coupled resonant system. In this research, the effects of residual layer from the nanoimprinting process of micro-pillars and polydispersity index (Pd) of PMMA molecules on the sensitivity of QCM-P devices are investigated both experimentally and theoretically. The results show the residual layer behaves as an additional mass and significantly reduces the frequency shift of QCM-P sensor while a low polydispersity of PMMA improves the sensor responses. The outcome of this research leads to an in-depth understanding of the effects of material and fabrication process on QCM-P sensors which will build a solid foundation for the further improvement of QCM-P devices for a variety of applications such as protein binding measurement in drug discovery, gas detection for environmental monitoring and protection.

Abstract:

The Country Diagnostic Study (CDS) for Senegal uses the Hausmann-Rodrik-Velasco growth diagnostics model to identify the binding constraints being faced in its quest for higher and more sustained economic growth and make recommendations to relax these constraints. Hence, the findings of the CDS can help the Islamic Development Bank in identifying areas where it can have a greater impact and provide an evidence-basis to support the development of the Member Country Partnership Strategy. After decades of subdued and highly volatile economic growth due to heavy dependence on primary commodities and low productivity, Senegal experienced an unprecedented growth acceleration from 2014 to 2019. However, there appeared to be a weak correlation between economic growth and jobs creation. In addition, about 90 percent of non-agricultural employment is estimated to be informal. The national poverty rate decreased by 5 percentage points between 2011 and 2018. Nonetheless, the absolute number of poor people has increased. Furthermore, regional disparities are persistent. Despite the country’s solid performance in the field of governance, further simplification and transparency of business procedures and regulations will be critical in addressing the challenge of informality. Efforts to address informality in the economy should also target the issue of access to finance through the design of financing mechanisms based on specific needs assessment and risk management tools. Senegal will also need to create the conditions for higher competitiveness and follow upgrading trajectories in global and regional value chains. In this respect, both physical and digital connectivity will be essential.
