Abstract:
In order to survive in an oxygen environment, aerobic organisms have developed numerous mechanisms to protect against oxygen radicals and singlet oxygen. One such mechanism, which appears to have attained particular significance during primate evolution, is the direct scavenging of oxygen radicals, singlet oxygen, oxo-haem oxidants and hydroperoxyl radicals by uric acid. In the present paper we demonstrate that another important ‘antioxidant’ property of uric acid is the ability to form stable co-ordination complexes with iron ions. Formation of urate-Fe3+ complexes dramatically inhibits Fe3+-catalysed ascorbate oxidation, as well as lipid peroxidation in liposomes and rat liver microsomal fraction. In contrast with antioxidant scavenger reactions, the inhibition of ascorbate oxidation and lipid peroxidation provided by urate's ability to bind iron ions does not involve urate oxidation. Association constants (Ka) for urate-iron ion complexes were determined by fluorescence-quenching techniques. The Ka for a 1:1 urate-Fe3+ complex was found to be 2.4 × 10(5), whereas the Ka for a 1:1 urate-Fe2+ complex was determined to be 1.9 × 10(4). Our experiments also revealed that urate can form a 2:1 complex with Fe3+ with an association constant for the second urate molecule (K'a) of approx. 4.5 × 10(5). From these data we estimate an overall stability constant (Ks approximately equal to Ka × K'a) for urate-Fe3+ complexes of approx. 1.1 × 10(11). Polarographic measurements revealed that (upon binding) urate decreases the reduction potential for the Fe2+/Fe3+ half-reaction from −0.77 V to −0.67 V. Thus urate slightly diminishes the oxidizing potential of Fe3+. The present results provide a mechanistic explanation for our previous report that urate protects ascorbate from oxidation in human blood. The almost saturating concentration of urate normally found in human plasma (up to 0.6 mM) represents 5-10 times the plasma ascorbate concentration, and is orders of magnitude higher than the ‘free’ iron ion concentration. These considerations point to the physiological significance of our findings.

Abstract:
This study investigates the decolorization of C.I. Reactive Red 2 (RR2) by the UV/TiO2, UV/ZnO, UV/TiO2/ZnO, O3, UV/O3, O3/MnO2, UV/H2O2, UV/H2O2/Fe3+, UV/O3/H2O2, and UV/O3/H2O2/Fe3+ systems. The values of the electrical energy per order of pollutant removal (EEO) and decolorization rate were determined and compared for all tested systems. The decolorization rate constant (ka) fit pseudo-first-order kinetics. Under 365 nm irradiation, the highest ka value and lowest EEO value were with the UV/O3 (0.0924 min-1) and O3/MnO2 (1.68) systems, respectively. Moreover, under 254 nm irradiation, the highest ka value and lowest EEO value were with the UV/O3/H2O2/Fe3+ (0.096 min-1) and UV/H2O2/Fe3+ (2.01) systems, respectively.

Abstract:
Causality from the capital account (KA) to the current account (CA) of the balance of payments indicates disruption from capital flows while the reverse can indicate smooth financing of the CA that allows investment to exceed domestic savings. A three-variable vector autoregression tests for Granger causality between the Indian CA, KA, KA components, and gross fixed capital formation (GFCF) over 2000–01Q1 to 2015–16Q3. Since a CA deficit indicates an excess of investment over savings it is useful to estimate which type of capital flows affect investment. No causality is found to exist in any direction between the KA and the CA. There is only indirect causality through some components. Of the capital flow components, only FDI affects GFCF. The latter consistently affects the CA. The CA affects debt portfolio flows and non-resident deposits, suggesting these were used to finance the CA, but they were not causal for GFCF. Volatile flows, therefore, did not deteriorate the CA, but they also did not contribute to GFCF. India’s gradual KA convertibility may have mitigated shocks from the KA. Long-term sustainability, however, requires FDI to increase as compared to other types of flows. JEL Codes: F21, F32

Abstract:
ABSTRACT MntH, a bacterial homolog of the mammalian natural resistance-associated macrophage protein 1 (Nramp1), is a primary Mn2+ transporter of Salmonella enterica serovar Typhimurium and Escherichia coli. S. enterica serovar Typhimurium MntH expression is important for full virulence; however, strains carrying an mntH deletion are only partially attenuated and display no obvious signs of Mn2+ deficiency. We noted that promoter sequences for mntH and for the putative Fe2+ transporter sitABCD appeared to have the same regulatory element responsive to Mn2+ and so hypothesized that sitABCD could transport Mn2+ with high affinity. We have now characterized transport by SitABCD in S. enterica serovar Typhimurium using 54Mn2+ and 55Fe2+ and compared its properties to those of MntH. SitABCD mediates the influx of Mn2+ with an apparent affinity (Ka ) identical to that of MntH, 0.1 μM. It also transports Fe2+ but with a Ka 30 to 100 times lower, 3 to 10 μM. Inhibition of 54Mn2+ transport by Fe2+ and of 55Fe2+ transport by Mn2+ gave inhibition constants comparable to each cation's Ka for influx. Since micromolar concentrations of free Fe2+ are improbable in a biological system, we conclude that SitABCD functions physiologically as a Mn2+ transporter. The cation inhibition profiles of SitABCD and MntH are surprisingly similar for two structurally and energetically unrelated transporters, with a Cd2+ Ki of ≈1 μM and a Co2+ Ki of ≈20 μM and with Ni2+, Cu2+, and Fe3+ inhibiting both transporters only at concentrations of >0.1 mM. The one difference is that Zn2+ exhibits potent inhibition of SitABCD (Ki = 1 to 3 μM) but inhibits MntH weakly (Ki > 50 μM). We have previously shown that MntH transports Mn2+ most effectively under acidic conditions. In sharp contrast, SitABCD has almost no transport capacity at acid pHs and optimally transports Mn2+ at slightly alkaline pHs. Overall, coupled with evidence that each transporter is multiply but distinctly regulated at the transcriptional level, the distinct transport properties of MntH versus SitABCD suggest that each transporter may be specialized for Mn2+ uptake in different physiological environments.

Abstract:
The marine horseshoe crab (Tachypleus tridentatus) has been considered as food and traditional medicine for many years. Kynurenic acid (KA) was isolated from horseshoe crab in this study for the first time in the world. A previous study in 2018 reported that intraperitoneal administration of KA prevented high-fat diet- (HFD-) induced body weight gain. Now, we investigated the effects of intragastric gavage of KA on HFD mice and found that KA (5 mg/kg/day) inhibited both the body weight gain and the increase of average daily energy intake. KA reduced serum triglyceride and increased serum high-density lipoprotein cholesterol. KA inhibited HFD-induced the increases of serum low-density lipoprotein cholesterol, coronary artery risk index, and atherosclerosis index. KA also suppressed HFD-induced the increase of the ratio of Firmicutes to Bacteroidetes (two dominant gut microbial phyla). KA partially reversed HFD-induced the changes in the composition of gut microbial genera. These overall effects of KA on HFD mice were similar to that of simvastatin (positive control). But the effects of 1.25 mg/kg/day KA on HFD-caused hyperlipidemia were similar to the effects of 5 mg/kg/day simvastatin. The pattern of relative abundance in 40 key genera of gut microbiota from KA group was closer to that from the normal group than that from the simvastatin group. In addition, our in vitro results showed the potential antioxidant activity of KA, which suggests that the improvement effects of KA on HFD mice may be partially associated with antioxidant activity of KA. Our findings demonstrate the potential role of KA as a functional food ingredient for the treatment of obesity and hyperlipidemia as well as the modulation of gut microbiota.

Abstract:
AbstractStable isotope analysis along with radiocarbon and luminescence dating of late Pleistocene lacustrine deposits at Burfu in the higher central Himalaya are used to interpret hydrologic changes in the lake basin. From 15.5 ka to ~ 14.5 ka the Burfu lake was largely fed by melting glaciers. A warming event at 14.5 ka suggests an enhanced monsoon and increased carbonate weathering. From ~ 13.5 ka to ~ 12.5 ka the isotopic data suggest large-amplitude climate variability. Following this, the isotope data suggest a short-lived, abrupt cooling event, comprising a ~ 300-yr intense cool period followed by a ~ 500-yr interval of moderate climate. A shift in isotope values at ~ 11.3 ka may signify a strengthening monsoon in this region. The inferred climatic excursions appear to be correlative, at least qualitatively, with global climatic events, and perhaps the Burfu lake sequence provides regional evidence of globally recorded excursions. This study also suggests a potential use of radiocarbon ages in specific environments as a paleoenvironmental proxy.

Abstract:
AbstractLow-protein diet plus ketoacids (LPD+KA) has been reported to decrease proteinuria in patients with chronic kidney diseases (CKD). However, the mechanisms have not been clarified. As over-activation of intrarenal renin–angiotensin system (RAS) has been shown to play a key role in the progression of CKD, the current study was performed to investigate the direct effects of LPD+KA on intrarenal RAS, independently of renal haemodynamics. In this study, 3/4 subtotal renal ablated rats were fed 18 % normal-protein diet (Nx-NPD), 6 % low-protein diet (Nx-LPD) or 5 % low-protein diet plus 1 % ketoacids (Nx-LPD+KA) for 12 weeks. Sham-operated rats fed NPD served as controls. The level of proteinuria and expression of renin, angiotensin II (AngII) and its type 1 receptors (AT1R) in the renal cortex were markedly higher in Nx-NPD group than in the sham group. LPD+KA significantly decreased the proteinuria and inhibited intrarenal RAS activation. To exclude renal haemodynamic impact on intrarenal RAS, the serum samples derived from the different groups were added to the culture medium of mesangial cells. It showed that the serum from Nx-NPD directly induced higher expression of AngII, AT1R, fibronectin and transforming growth factor-β1 in the mesangial cells than in the control group. Nx-LPD+KA serum significantly inhibited these abnormalities. Then, proteomics and biochemical detection suggested that the mechanisms underlying these beneficial effects of LPD+KA might be amelioration of the nutritional metabolic disorders and oxidative stress. In conclusion, LPD+KA could directly inhibit the intrarenal RAS activation, independently of renal haemodynamics, thus attenuating the proteinuria in CKD rats.

Abstract:
This chapter negotiates the art of representing crisis and the crisis of representation as shown in the visual and discursive modes of cinematic portrayals of Hong Kong’s political change in the post-1997 era. Through a closer look at Ten Years (Shi nian , dir. Kwok Zune, Fei-Pang Wong, Jevons Au, Kwun-Wai Chow, Ka-Leung Ng, 2015) and independent documentaries on young Umbrella protesters such as Lesson in Dissent (dir. Matthew Torne, 2014), Joshua: Teenager vs. Superpower (dir. Joe Piscatella, 2017) and Lost in the Fumes (Dihou tiangao , dir. Nora Lam, 2017), this study argues that these films reframe social and political upheavals and youth activism in historical perspective and bend various genres aesthetically. Carving out their niche audience at community screening events and international film festivals, both local and foreign filmmakers employ cinema as a powerful tool of political critique, re-evaluating the different forms of Chinese dominance over the postcolonial city.

Abstract:
Glass Fibre Reinforcement Plastic (GFRP) is widely used in engineering fields including aerospace, marine and construction, etc. During practical service, it is prone to the impact damage leading to the Localized Thickness Loss (LTL) which severely influences the integrity and safety of GFRP. To detect and evaluate LTL in GFRP, common Non-Destructive Testing (NDT) techniques such as ultrasonic testing and thermography are usually applied. Complementary to these methods, microwave NDT has been found to be one of the promising techniques in quantitative evaluation of GFRP. In this paper, the characterization and imaging of LTL in GFRP by microwave NDT are intensively investigated. A 2D Finite Element Model (FEM) with the Ka-band open-ended waveguide and GFRP sample subject to LTL has been set up and adopted for analysis of field characteristics and testing signals. Following that, an experimental investigation is conducted to further study the feasibility of LTL imaging by microwave NDT with the Ka-band open-ended waveguide. The results from simulations and experiments indicate the applicability of Ka-band microwave open-ended waveguide for detection and evaluation of LTL in GFRP.

Abstract spellings like po-pi ‘with feet’ have been interpreted as propr0i, namely, with assimilation of the stem-final stop to the point of articulation of the ending.

Abstract:
Dated to ca. 400 ka (Marine Isotope Stage 11), the site of Gruta da Aroeira (Torres Novas, Portugal) is one of the very few Middle Pleistocene localities that have yielded a fossil hominin cranium associated with Acheulean bifaces, in a cave context. Our multi-analytical approach to the site’s archaeological record focused on different aspects: the human cranium (Aroeira 3), the faunal remains, the use of fire, and the lithic industry. The Aroeira 3 fossil cranium displays a primitive bony labyrinth and a perimortem bone fracture. The lithic assemblage suggests limited mobility, with on-site knapping; the bifaces, however, were brought to the site as finished tools. Among the faunal remains, the primate Macaca sylvanus is present and cervids, including the Mediterranean deer Haploidocerus mediterraneus, previously undocumented in the Middle Pleistocene of the Iberian Peninsula, predominate. Paleoenvironmental reconstruction using the small vertebrate assemblage suggests an open woodland landscape with semi-humid conditions. The presence of combustion by-products supports the controlled use of fire by the peoples of the Acheulean.

Abstract The line ‘Everything is fair in love and war’ is very suitable for the tug of war between on and offline in the retail sector as both players of on and off are adopting various marketing strategies to attract and retain the customers and there are clashes of marketing offerings which is making the king of the market—customer delighted. For sustaining and surviving in this global competitive business world, all are in the hurry to differentiate themselves from others by hook or crook and only that would be the market leader who will be the fittest among all. From ‘Big Billion Day Sale’ on Flipkart to Big Bazaar’s ‘Saal ka Sabse Sasta Din’, the war is on to acquire more and more customers in a short span of time are the current marketing strategies adopted by companies of marketplaces and market spaces. The key question from a policy point of view is whether this is a momentary or enduring trend as many popular on and offline companies are on the border of failure as they are making losses while very few are successful. Students in marketing management will find this case study interesting to see how the online and offline retail networks are strengthening their cobwebs to trap major footfalls and customer groups. In India, it was Mr Kishore Biyani, the promoter of Future group, instrumental in introducing the mall culture and the offline retail almost a decade ago. Based on the response the Future group received for its offline retail business, many other major players like the Shoppers Stop, Flip Kart, Aditya Birla group in readymade garments, the Tatas in Trent, and many in fast food retailers have by now crowded the Indian online and offline retail market including now the giant killer Amazon following the Walmart who entered India almost in the early 2000s. This case study tries to take a sample cut of the warlike situation of severe competition now prevalent in Indian offline and online retail and the street fight between Future group and the FlipKart to snatch away each other’s customer base by luring with all types of discounts and sales offers including emptying of the waste boxes of customers.

Abstract:
In this paper the free-electron laser (FEL) study in China is presented. The FEL theoretical research in China commenced in the mid- 1970s, but experiments commenced later. In 1987 Hefei National Synchrotron Radiation Laboratory, in cooperation with Shanghai Institute of Optics and Fine Mechanics, produced an experiment based on rf linac of 30 MeV, in which an infrared radiation at wavelength of 10 µm is observed. In 1988 China Academy of Engineering Physics (CAEP) had performed an experiment based on pulse line accelerator, in which 7.6 MW radiation has been observed at 36.9 GHz representing 5% efficiency. These early experiments were characterized by small efficiency due to poor quality of electron beams at the time. However, now the induction linac of 4 MeV and 1 kA with qualitative electron beam is projected for SG 1 FEL amplifier by CAEP and 30 MeV rf linac is being upgraded by Institute of High Energy Physics to provide electron beam for FEL oscillator in the infrared region. The FEL with electromagnet wave pump is projected by University of Electronics Science and Technology of China. The superconductor accelerator is by accelerator laboratory of Peking University and the Cherenkov FEL experiment is produced by Changsha Polytechnic Institute. Now the FEL research is intensely produced by theoretical and experimental aspect in China.
