background: nail disorders comprise approximately 10% of all dermatological conditions. abnormalities in the color of nails are called ungal dyschromia or chromonychia. ungual dyschromia may be endogenous or exogenous. yellow discoloration of the nails has been reported during the last years as separate observation related to drug administration, during hemodialysis and associated with pulmonar...

nanosilver of nanometer-sized silver (ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. boric acid (h3bo3) is water soluble (ph=7). boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the acc synthase and acc oxidase delays senescence of flower. in this study of different concentrations of boric acid and nano-silver was eva...

ZnO- nanoparticles with an average particle size of 24 nm were successfully synthesized using the microwave assisted sol- gel technique. Structural and morphological properties of the nanoparticles were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Energy disperse spectrum (EDS) and Fourier transform infrared spectroscopy (FTIR). The band gap ene...

The trophic linkage between yellow perch Perca flavescens and two exotic prey items, alewife Alosa pseudoharengus and round goby Neogobius melanostomus, was investigated in the extreme southern area of Lake Michigan during the summer of 2002. Yellow perch 100mm total length, LT (n1⁄4 1293) exhibited size selective feeding, with 148 fish containing round gobies and 120 fish containing alewives. ...

Bitter apple or tumba (Citrullus colocynthis L.) is a prostrate annual herb belonging to the Cucurbitaceae family. It highly tolerant against multiple abiotic stresses like drought, heat, and soil salinity can easily grow on very marginal soil, even sand dunes in hot, arid regions. Tumba fruit fleshy berry 5–10 cm diameter of pale yellow color at ripening. The used this research was harvested f...

Different colored bell peppers (Capsicum annuum L.), green, red, and yellow were examined for their content of phenolic compounds, ascorbic acid and carotenoids as well as free radical scavenging activity using DPPH assay and antioxidant activity using ß-carotene/linoleic acid assay. Phenolic, ascorbic acid and carotenoid contents varied in different colored bell peppers. Green pepper had highe...
