Preliminary phytochemical screening and antimicrobial activity of Samanea saman

Samanea saman is a tropically distributed medicinal plant. Antimicrobial activity of aqueous extract of this plant was investigated by Well-diffusion method against three organisms: Escherichia coli, Staphylococcus aureus and Candida albicans. The plant extract showed inhibitory activity against all the tested organisms. Five mg/ml inhibited the growth of E. coli but slightly higher concentration of 10 mg/mL was necessary to show inhibition against S. aureus and C. albicans. Phytochemical screening of the plant revealed the presence of tannins, flavonoides, saponins, steroids, cardiac glycosides and terpenoids. The study scientifically validates the use of plant in traditional medicine

Analysis of Antibody and Cytokine Markers for Leprosy Nerve Damage and Reactions in the INFIR Cohort in India

Leprosy is one of the oldest known diseases. In spite of the established fact that it is least infectious and a completely curable disease, the social stigma associated with it still lingers in many countries and remains a major obstacle to self reporting and early treatment. The nerve damage that occurs in leprosy is the most serious aspect of this disease as nerve damage leads to progressive impairment and disability. It is important to identify markers of nerve damage so that preventive measures can be taken. This prospective cohort study was designed to look at the potential association of some serological markers with reactions and nerve function impairment. Three hundred and three newly diagnosed patients from north India were recruited for this study. The study attempts to reflect a model of nerve damage initiated by mycobacterial antigens and maintained by ongoing inflammation through cytokines such as Tumour Necrosis Factor alpha and perhaps extended by antibodies against nerve components

NON SYMBOLIC BASE64: AN EFFECTIVE REPRESENTATION OF IPV6 ADDRESS

ABSTRACT The Transition from IPv4 to IPv6 is necessary due to introduction of cloud computing which made spectacular changes to IT Industry in recent years. As IPv6 deployment increases, there will be a dramatic increase in the need to use IPv6 addresses and so many services running in Cloud computing will face problems associated with IPv6 addressin

Development and Identification of Novel Rice Blast Resistant Sources and Their Characterization Using Molecular Markers

To develop and characterize introgression lines for leaf and neck blast resistance, 326 introgression lines were developed using various accessions of six different AA genome wild species in the genetic background of elite Indian varieties like PR114 and Pusa 44 and were screened for blast resistance. Stringent phenotyping coupled with genotyping using gene based markers led to the identification of four resistant introgression lines, which showed promising resistance and do not possess any of the tested genes. Furthermore, multi-location screening confirmed the field resistance of the four introgression lines to both leaf and neck blast. Molecular characterization of these introgression lines using genome-wide simple sequence repeat markers revealed the presence of small percentage of wild Oryza genome introgrssion. So these lines can be used for mapping and identification of novel leaf and neck blast resistance genes. Thus, these four introgression lines can be considered as new genetic resources for blast resistance

Stable, Surfactant‐Free Graphene–Styrene Methylmethacrylate Composite for Ultrafast Lasers

This is the author accepted manuscript. It is currently under an indefinite embargo pending publication by Wiley.Graphene-polymer composites play an increasing role in photonic and optoelectronic applications, from ultrafast pulse generation to solar cells. We report the fabrication of an optical quality surfactant-free graphene-styrene methyl methacrylate composite, stable to large humidity and temperature ranges and show its use for photonic applications. The composite shows wavelength-independent linear absorption in the visible and near-infrared. When tested in a mode-locked laser, it allows the generation of stable ∼326 fs mode-locked pulses at 1550 nm, unperturbed by environmental conditions. The composite continues to operate as a saturable absorber even under complete water immersion at 60◦C. This confirms its stability against high-temperature and humidity.We acknowledge funding from the synergy grant Hetero2D, the EU Graphene Flagship (n. 604391), a Royal Society Wolfson Research Merit Award, the EPSRC grants EP/K01711X/1, EP/K017144/1, EP/L016087/1 and the EU FP7 project MEM4WIN.
