Ramesh Chandra: Influence Statistics

BACKGROUND: Nipah Virus (NiV) is a highly fatal emerging zoonotic virus and a potential threat to global health security. Here we describe the characteristics of the NiV outbreak that occurred in Kerala, India, during May-June 2018.

METHODS: We used real-time reverse transcription polymerase chain reaction analysis of throat swab, blood, urine, and cerebrospinal fluid specimens to detect NiV. Further, the viral genome was sequenced and subjected to phylogenetic analysis. We conducted an ...

In this work, a facile and novel approach is presented to maintain stoichiometry, to achieve stable nanostructure and high surface area manganese oxide (α-MnO2). The synthesis of α-MnO2 nanorods forest has been carried out using reactive DC magnetron sputtering technique without use of surfactant/wet chemical procedure. The structural parameters, vibrational response and surface morphology of the α-MnO2 nanorods are characterized using X-ray diffraction (XRD), Raman spectroscopy, Fourier ...

The recent reports of artemisinin (ART) resistance in the Thai-Cambodian border area raise a serious concern on the long-term efficacy of ARTs. To elucidate the resistance mechanisms, we performed in vitro selection with dihydroartemisinin (DHA) and obtained two parasite clones from Dd2 with more than 25-fold decrease in susceptibility to DHA. The DHA-resistant clones were more tolerant of stressful growth conditions and more resistant to several commonly used antimalarial drugs than ...

The efficiency of ZrO2 nanoparticles for the decontamination of 2-choro ethyl ethyl sulphide (CEES) and dimethyl methyl phosphonate (DMMP) has been studied. Nanoparticles have been synthesized using reactive magnetron sputtering technique and characterized using Powder XRD, FE-SEM, TEM, Raman spectroscopy, N2-BET, TGA and FT-IR techniques. XRD patterns indicate that the as-deposited nanoparticles are amorphous in nature. After annealing at 300°, 450° and 600°C, they transform from ...

Present work deals with the synthesis of copper oxide nanoparticles using reactive magnetron sputtering technique and its adsorptive removal properties for the Pb (II) ions from the aqueous solution. The characterizations of synthesized nanoparticles were carried out using powder XRD, FT-IR, Raman, FE-SEM, EDS, TEM, SAED, BET surface area techniques. The XRD result exhibits monoclinic phase with average crystallite size ~9nm. Raman analysis further confirms the XRD data. TEM result ...

Surfactant free ZnO and Cu doped ZnO nanorods were synthesized by hydrothermal method. The formation of ZnO:Cu nanorods were confirmed by scanning electron microscopy, X-ray diffraction and Raman analysis. Diffuse reflectance spectroscopy results shows that band gap of ZnO nanorods shifts to red with increase of Cu content. The orange-red photoluminescent emission from ZnO nanorods originates from the oxygen vacancy or ZnO interstitial related defects. ZnO:Cu nanorods showed strong ...

Nanocrystalline TiN thin films were deposited on glass substrate by d.c. magnetron sputtering. The microstructural characteristics of the thin films were characterized by XRD, FE-SEM and AFM. XRD analysis of the thin films, with increasing thickness, showed the (200) preferred orientation up to 1·26 μm thickness and then it transformed into (220) and (200) peaks with further increase in thickness up to 2·83 μm. The variation in preferred orientation was due to the competition between ...

The capabilities of soil microorganisms to solubilize phosphate have been known for many years, but their isolation and use as crop inoculants have met with little success. Thirty-five bacterial isolates were screened for their phosphate-solubilizing ability, and two of them, PSR10 and RGR13, identified through 16S rDNA sequencing as Chryseobacterium sp. PSR10 and Escherichia coli RGR13, respectively, screened for plant growth promotion in the greenhouse. Seed inoculation of Macrotyloma ...

Among numerous active electrode materials, manganese oxides are promising electrodes in supercapacitors. Manganese oxides research has thus far focused on the synthesis of one-dimensional (1-D) metal oxide nanostructured materials, which can have superior electrochemical performance. Several chemical methods are used to synthesize metal oxide nanostructured which involve toxic reagents, solvents and introduction of byproducts. However, physical method offers an eco-friendly path to ...

Strains of Pseudomonas aeruginosa (PA) isolated from the airways of cystic fibrosis patients constitutively add palmitate to lipid A, the membrane anchor of lipopolysaccharide. The PhoPQ regulated enzyme PagP is responsible for the transfer of palmitate from outer membrane phospholipids to lipid A. This enzyme had previously been identified in many pathogenic Gram-negative bacteria, but in PA had remained elusive, despite abundant evidence that its lipid A contains palmitate. Using a ...

In this paper, the influence of patch parameters on stress intensity factors in edge cracked plates is studied by employing transmission photoelasticity. Edge cracked plates made of photo-elastic material are patched on one side only by E glass-epoxy and carbon-epoxy unidirectional composites. The patch is located on the crack in such a way that the crack tip is not covered. Magnified isochromatic fringes are obtained by using a projection microscope of magnification 50, converted into a ...

WHEN conservative management fails to produce effective results in patients with vasomotor rhinitis, vidian neurectomy can be very helpful. It is also indicated for patients with "crocodile tears" after tympanic neurectomy fails.1A satisfactory surgical approach for vidian neurectomy has been aided by the search for the sphenopalatine ganglion for the treatment of sphenopalatine neuralgia. Sewell2 has advocated the transantral approach to the sphenopalatine ganglion and others3-6 have ...

Adult incomplete cleft lip nose deformity is not uncommon in India. Poverty, ignorance, and parental neglect account for its late presentation. Besides the classical features of cleft lip nose deformity, the constant findings observed in this patient population have been a widened and depressed nasal sill. This is attributable to the sparse, hypoplastic, and abnormally orientated orbicularis oris muscle in the region of the sill. Failure to restore the nasal sill symmetry by suitably ...
