| 1 | Effect of Thickness of SnO_2:F over Layer on Certain Physical Properties of ZnO:Al Thin Films for Opto-electronic Applications显示文摘Bilayered FTO/AZO (fluorine doped tin oxide/aluminium doped zinc oxide) films were fabricated using a simple, cost effective spray pyrolysis technique. X-ray diffraction (XRD) profiles of bilayered films showed that in the case of lower thickness FTO over layers, (002) plane of ZnO phase had the highest intensity, whereas the predominance was changed in favour of (200) plane of SnO 2 phase for higher thickness FTO over layer. UV studies showed that bilayered FTO/AZO films exhibited a sharp absorption edge as that of AZO film. The decrease in the photoluminescence (PL) peak at 420 nm with increasing FTO over layer thickness indicated a reduction in the zinc vacancies which caused a reduction in the sheet resistance (R sh ). Electrical studies revealed that, eventhough the R sh value (916Ω /□ ) of bilayered FTO (313 nm)/AZO (314 nm) film was found to be higher than that of FTO single layer film (72Ω /□ ), it was much lower than that of AZO single layer film (5661 Ω/ □). The atomic force microscopy (AFM) images reflect the characteristic features of both zinc oxide and tin oxide films. | P. Ravikumar K. Ravichandran B.

| 2 | Memory consolidation during sleep and adult hippocampal neurogenesis显示文摘In anticipation of the massive burden of neurodegenerative disease within super-aged societies, great efforts have been made to utilize neural stem and progenitor cells for regenerative medicine. The capacity of intrinsic neural stem and progenitor cells to regenerate damaged brain tissue remains unclear, due in part to the lack of knowledge about how these newly born neurons integrate into functional circuitry. As sizable integration of adult-born neurons naturally occurs in the dentate gyrus region of the hippocampus, clarifying the mechanisms of this process could provide insights for applying neural stem and progenitor cells in clinical settings. There is convincing evidence of functional correlations between adult-born neurons and memory consolidation and sleep; therefore, we describe some new advances that were left untouched in our recent review. | Iyo Koyanagi Katherine G.Akers Pablo Vergara Sakthivel Srinivasan Takeshi Sakurai Masanori Sakaguchi | 2019 | Neural Regeneration Research2019，14，1： | 4 |
| 3 | Free radical scavenging potential and HPTLC analysis of Indigofera tinctoria linn(Fabaceae)显示文摘The objective of this study was to evaluate the free radical scavenging potential and high performance thin layer chromatography(HPTLC) fingerprinting of Indigofera tinctoria(I. tinctoria). Phytochemical analysis was carried out using standard methods, and free radical scavenging activity of the plant was determined using 2,2-diphenyl-1-picrylhydrazy(DPPH), nitric oxide(NO) and superoxide anion(O_2^-)radical scavenging capacities. HPTLC plate was kept in CAMAG TLC Scanner 3 and the Rf values at fingerprint data were recorded by WINCATS software. Aqueous extract of I. tinctoria reliably showed the total phenolics(267.2±2.42 mg/g), flavonoids(75.43±3.36 mg/g) and antioxidants(349.11±8.04 mg/g). The extract was found to have DPPH(52.08%), NO(23.12%) and O_2^-(26.79%) scavenging activities at the concentration of 250 μg/m L and the results were statistically signi ficant compared with ascorbic acid standard(p<0.05). HPTLC results con firmed that the extract contained several potential active components such as phenols, flavonoids, saponins and terpenoids as the slides revealed multi-colored bands of varying intensities. This study confirmed that the plant had multipotential antioxidant and free radicals scavenging activities. | Sakthivel Srinivasan Wankupar Wankhar Sheeladevi Rathinasamy Ravindran Rajan | 2016 | Journal of Pharmaceutical Analysis2016，6，2： | 2 |
| 4 | Imidazolium-Based Ionic Liquids as an Anticorrosive Agent for Completion Fluid Design显示文摘Most of the onshore and offshore oil and gas reservoirs are facing operational challenges due to high temperature and high salinity, thus requiring advanced techniques for realizing the expected oil recovery with the use of specially designed chemicals. During oil and gas well development, completion fluids, which are solids-free liquids, are used to complete an oil or gas well. Completion fluids consisting of brines are primarily used for oil and gas well stabilization and are corrosive in nature. There is a need to develop additives to be added with completion fluids to address the corrosive nature. The present investigation involved the usage of two imidazolium ionic liquids(ILs) as corrosion inhibitors for mild steel in various completion brine(Ca Cl_2, HCOOCs and ZnBr_2) fluids. The study was performed using various techniques, such as, potentiodynamic polarization, weight loss measurements and exposure studies. All the above techniques showed promising results which indicated that the ILs as corrosion inhibitors used were of the mixed-type following both physisorption and chemisorption over the mild steel surface. Among the two inhibitors studied here, 1-octyl-3-methyl imidazolium chloride([OMIM]^+[Cl]^-) with longer alkyl chain exhibited better inhibition efficiency and much lesser corrosion rate than 1-butyl-3-methyl imidazolium chloride([BMIM]^+[Cl]^-) with a shorter alkyl chain. The results obtained from various methodologies indicate that ionic liquids can be explored to develop anti-corrosive completion fluids suitable for oil and gas reservoirs. | Sugirtha Velusamy Sivabalan Sakthivel Lakshman Neelakantan Jitendra S.Sangwai | 2017 | Journal of Earth Science2017，28，5： | 2 |

| 8 | GDF15 promotes prostate cancer bone metastasis and colonization through osteoblastic CCL2 and RANKL activation显示文摘Bone metastases occur in patients with advanced-stage prostate cancer(PCa). The cell-cell interaction between PCa and the bone microenvironment forms a vicious cycle that modulates the bone microenvironment, increases bone deformities, and drives tumor growth in the bone. However, the molecular mechanisms of PCa-mediated modulation of the bone microenvironment are complex and remain poorly defined. Here, we evaluated growth differentiation factor-15(GDF15) function using in vivo preclinical PCa-bone metastasis mouse models and an in vitro bone cell coculture system. Our results suggest that PCa-secreted GDF15 promotes bone metastases and induces bone microarchitectural alterations in a preclinical xenograft model. Mechanistic studies revealed that GDF15 increases osteoblast function and facilitates the growth of PCa in bone by activating osteoclastogenesis through osteoblastic production of CCL2 and RANKL and recruitment of osteomacs. Altogether, our findings demonstrate the critical role of GDF15 in the modulation of the bone microenvironment and subsequent development of PCa bone metastasis. | Jawed Akhtar Siddiqui Parthasarathy Seshacharyulu Sakthivel Muniyan Ramesh Pothuraju Parvez Khan Raghupathy Vengoji Sanjib Chaudhary Shailendra Kumar Maurya Subodh Mukund Lele Maneesh Jain Kaustubh Datta Mohd Wasim Nasser Surinder Kumar Batra | 2022 | Bone Research2022，10，1： | 2 |
