chinaberry (melia azedarach l.) is a beautiful tree indigenous to the himalayas that grows as a native plant in iran. symptoms similar to bacterial gall have been observed on the crown, shoot and twig of chinaberry, a recent landscape tree since 2003-2004 in shiraz, fars province, south of iran. a gram negative bacterium was isolated from the galls. the isolates did not produce fluorescent pigm...

aflatoxin contamination of food and feedstuffs is a serious economic and health hazard. over a period of two years, 35 samples of raw pistachio nuts collected from different parts of iran were analysed for the presence of aflatoxigenic strains of the aspergillus flavus group. eighty-five isolates of a.flavus and a.parasiticuswere identified based on specific yello-orange pigment production in t...

The extracellular matrix of retinal pigment epithelial (RPE) cells is an important component of the fibroelastic membranes formed in proliferative vitreoretinopathy (PVR). These membranes consist of cells intermingled with fibrillar proteins, such as elastin and collagen. Because RPE cells may be exposed to vitreous and serum-derived factors in conditions that lead to PVR, the effects of vitreo...

PURPOSE The concentration of enhanced green fluorescent protein (EGFP) in individual photoreceptor cells of live mouse retina was quantified and correlated with physiological measurements of cell function. METHODS EGFP protein levels in the retinas of mice injected subretinally by either one of two serotypes of adeno-associated virus (AAV; AAV2/5.CMV.EGFP; AAV2/2.CMV.EGFP) were quantified wit...

PURPOSE Gene therapy has shown promise in animal models of retinal disease, with the most success achieved to date with viral vectors used for gene delivery. Viral vectors, however, have side effects and limitations and are difficult to manufacture. The present study was conducted in an attempt to develop a novel system for long-term gene transfer in rat retinal pigment epithelium (RPE), by usi...

California mice have been widely recognized as one of the few examples ‘true’ genetic monogamy in mammals and are only four mammalian species considered to be both genetically socially monogamous. The mating system this species, first described by David O. Ribble (1991), was initially investigated a single population integrating behavioral data DNA fingerprinting classify P. californicus Here, ...

The Federal Food, Drug, and Cosmetic Act of 1938 defines as adulterated any food that is composed in whole or in part of a filthy or decomposed substance. Objective laboratory and field tests for detection of decomposed products are always advisable to supplement organoleptic examinations. In any product where organoleptic tests fail because decomposition is masked by any means, objective tests...

PURPOSE To determine whether transduction with adeno-associated virus encoding green fluorescent protein (AAV-GFP) is useful for labeling transplanted retinal pigment epithelial cells (RPE). METHODS Transduction was performed by infection of confluent or subconfluent cultured feline RPE or by subretinal injection. Cells transduced in vitro were analyzed to determine label stability over time ...

The article presents the results of studying effect light-emitting diodes (LEDs) on efficiency micropropagation valuable woody plants. Commercial use requires optimization various parameters, including light quality and lighting regime. Nowadays, LED have become an alternative source illumination for plant tissue culture, Recently, along with medicinal herbaceous plants, tree crops also widely ...

The fluorescence shown by extracts of the heartwood of Pterocarpus marsupium is attributed to salts of the new compound 1, whose structure was elaborated using detailed spectroscopic/ spectrometric studies. The plant material also contains the nonfluorescent compounds 2 and 3. The absolute configuration of 1 was determined by experimental and theoretically calculated electronic CD spectra, whil...
