This study was undertaken to investigate the influence of plant probiotic fungus Piriformospora indica on the medicinal plant C. forskohlii. Interaction of the C. forskohlii with the root endophyte P. indica under field conditions, results in an overall increase in aerial biomass, chlorophyll contents and phosphorus acquisition. The fungus also promoted inflorescence development, consequently the amount of p-cymene in the inflorescence increased. Growth of the root thickness was reduced in P. indica treated plants as they became fibrous, but developed more lateral roots. Because of the smaller root biomass, the content of forskolin was decreased. The symbiotic interaction of C. forskohlii with P. indica under field conditions promoted biomass production of the aerial parts of the plant including flower development. The plant aerial parts are important source of metabolites for medicinal application. Therefore we suggest that the use of the root endophyte fungus P. indica in sustainable agriculture will enhance the medicinally important chemical production.

In the present study, the Moderate Resolution Imaging Spectroradiometer (MODIS) data retrieved from Terra satellite has been used to investigate the spatial and temporal variations in aerosol particles over North Eastern region of India for the period (2001-2010). Aerosol optical depths have found to be increased >15% across North Eastern part of India during the last decade (2001-2010). During the summer season, the mean AOD values (0.60±0.07) were observed whereas during the post monsoon season, mean AOD values were observed to be 0.07±0.02. Highest annual mean increase of AOD (> 79%) has been found over Guwahati. We then studied the relationship between AOD and five other cloud parameters namely water vapor, cloud fraction, cloud top temperature, cloud top pressure and cloud optical depth over North Eastern part of India so as to provide a better understanding of aerosol-cloud interaction. © 2013 Elsevier Ltd.

The present paper describes the study of defect modes in a one-dimensional photonic crystal (1d-PC) containing a high and low temperature superconductor as a defect layer at different temperatures below the superconducting transition temperature (T c ). Since the refractive index of the superconducting material is dependent on the penetration depth, which depends on the temperature of the superconducting material, hence by changing the temperature of the superconducting material its refractive index can also be changed. Analysis of the transmission spectra of defect modes in the reflection band of 1d-PC structure shows a shift in the wavelength peak of the defect mode. The shift in peak is different for different superconducting materials and it increases with the increase in temperature whether the defect layer is high T c or low T c superconductors. We also study the presence two defect layers in a 1d-PC structure, one with high T c and other with a low T c superconductor. Further, the effect of variation in the thickness of the defect layer on the defect modes of the PC structure has also been studied In order to obtain the transmission (reflection) spectra of a 1d-PC structure with a defect, we employ the transfer matrix method (TMM). This property of the defective PC structure can be exploited in designing the temperature sensor and narrow optical filters. Further, this tunable feature of superconductor photonic crystal has technical use in the superconducting electronics and photonics. © 2013 Springer Science+Business Media New York.

Mycotoxins that commonly occur in cereal grains and other products can contaminate finished processed foods on account of their high toxicity. The mycotoxins that are commonly associated with food grains include aflatoxins, ochratoxin A, fumonisins, deoxynivalenol, and zearalenone. Various food-processing operations include sorting, trimming, cleaning, cooking, baking, frying, roasting, flaking, and extrusion that have variable effects on mycotoxins. The nature of the processing operation viz. physical, chemical, or thermal plays an important role in this; usually, the processes that utilize the higher temperatures have greater effects on mycotoxin dissipation. In general, the processes are known to reduce mycotoxin concentrations significantly, but do not eliminate them completely. However, roasting and extrusion processing result in lowest mycotoxin concentrations, since these involve higher temperatures. It is observed that very high temperatures are needed to bring about high reduction in mycotoxin concentrations, approaching acceptable background levels. The treatment with chemicals like ammonia, bicarbonate, citric acid, or sodium bisulfite is also effective in resulting in significant decline in mycotoxin concentrations. © 2015, Copyright © Taylor & Francis Group, LLC.

With the emergence of more and more molecular markers as useful tools in plethora of population genetic and phylogenetic studies, choice of marker system for a particular study has become mind boggling. These marker systems differ in their advantages and disadvantages, so it is imperative to keep in mind all the pros and cons of the technique while selecting one for the problem to be addressed. Here, we have shed light on the ISSR (intersimple sequence repeat) technique, as a marker of choice if one wants to go for properties such as reliability, simplicity, cost effectiveness, and speed, in addition to assessing genetic diversity between closely related individuals. We have outlined here the whole methodology of this technique with an example of Tribulus terrestris as case study. © 2012 Springer Science+Business Media, LLC.

Aerosol optical depth (AOD) values at 550nm derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard NASA's Terra and Aqua satellites, for the 10 years period of 2003-2012 have been analyzed in the present study. The retrieved satellite data (Terra/Aqua) has been used to investigate the temporal heterogeneity in columnar aerosol characteristics over a semi arid urban tropical Delhi zone (28° 34', 77° 07', 233m ASL) of Northern India with a resolution of 1°×1° grid in magnitude. Aerosol optical depths have found to be increased >25% across Delhi region of India during the study period of 2003-2012. Yearly mean Terra/Aqua AOD values have shown an increasing trend at a rate of 0.005/0.009 per year respectively. However, seasonally winter means Terra/Aqua AOD values exhibit an increasing trend at a rate of ~0.012/0.007 per year respectively. In order to provide a better understanding of aerosol-cloud interaction, a single paired one tailed distribution student's t-Test has been applied to the Terra AOD values and cloud parameters. The results extracted in the present study are compared with the earlier studies as well as with the AOD values over various other Indian regions. © 2013 Elsevier Ltd.

In this study, we investigated the mechanism of brucine in tumor angiogenesis. We found that brucine inhibits VEGF-induced cell proliferation, chemotactic motility, and the formation of capillary-like structures in HUVECs in a dose-dependent manner. Brucine suppresses VEGF- induced p-VEGFR2 kinase activity and inhibits neovascularization in vivo. Brucine inhibits the downstream protein kinases of VEGFR2, including Src, FAK, ERK, AKT and mTOR. And further downregulates levels of VEGF, NO, IL-6, IL-8, TNF-α and IFN-γ in HUVECs. Taken together, our study suggests that brucine potently suppresses angiogenesis by targeting VEGFR2 activation and may be a viable drug candidate in anti-angiogenesis and anti-cancer therapies. © 2013 Elsevier Ireland Ltd.

Researchers at North Carolina State University have developed a new technique for creating NV-doped single-crystal nanodiamonds, only four to eight nanometers wide, which could serve as components in room-temperature quantum computing technologies. These doped nanodiamonds also hold promise for use in single-photon sensors and nontoxic, fluorescent biomarkers. The researchers are currently talking with government and private sector groups about how to move forward. One area of interest is to develop a means of creating self-assembling systems that incorporate entangled NV-doped nanodiamonds for quantum computing. Scientists from Amity University say they have developed an ultra-sensitive paper chip that quickly detects small amounts of ketamine — a date rape drug —in biological samples as well as in beverages. The researchers say that the current method employs a paper-based electrode system, made of zeolites nanoflakes and graphene-oxide nanocrystal, for electro analytical determination of ketamine. Using paper for the material means that the device will cost less, compared to metal-based electrode sensors. Finally, researchers at the University of Houston have reported a new method for inducing superconductivity in non-superconducting materials, demonstrating a concept proposed decades ago but never proven. The technique can also be used to boost the efficiency of known superconducting materials, suggesting a new way to advance the commercial viability of superconductors. The research, demonstrating a new method to take advantage of assembled interfaces to induce superconductivity in the non-superconducting compound calcium iron arsenide, offers a new approach to finding superconductors that work at higher temperatures.
