Antibodies cross-reactive with specific membrane proteins were used to investigate membrane development in Anacystis nidulans R2 during recovery from iron stress. Polyclonal antibodies prepared using the iron-regulated chlorophyll (Chl)-protein CPVI-4 (HB Pakrasi, HC Riethman, LA Sherman 1985 Proc Natl Acad Sci USA 82: 6903-6907) as antigen were characterized and used to identify three iron str...

This paper reviewed over 100 articles on the subject of the mechanism of catalyst layer (CL) degradation and the effect of various contaminations in the polymer electrolyte membrane fuel cell (PEMFC). Also the recovery of PEMFC via different types of methods, the causes and fundamental mechanisms of cell degradation and their influence on long- term performance of PEM fuel cell were discussed i...

where [Na]o and [Na]i are the sodium concentrations in bathing fluid and musclefiber water respectively, E,~ the mean membrane potential of the muscle fibers (outside minus inside) measured in recovery fluid, and T, R, and F the absolute temperature and gas and Faraday constants, respectively. I t was found (Conway, Kernan, and Zadunaisky, 1961) that a critical energy barrier to the active tran...

Obtaining quantitative kinetic parameters from fluorescence recovery after photobleaching (FRAP) experiments generally requires a theoretical analysis of protein mobility and appropriate solutions for FRAP recovery derived for a given geometry. Here we provide a treatment of FRAP recovery for a molecule undergoing a combined process of reversible membrane association and lateral diffusion on th...

MacConkey-inositol-carbenicillin agar has successfully been used as a primary selective medium for Klebsiella enumeration. With pure cultures, nearly 100% recovery of Klebsiella was observed by membrane filtration. With environmental samples using membrane filtration, 95% of typical pink- to red-colored colonies were verified as Klebsiella, as opposed to only 1% of yellow background colonies. R...

probable use of chemical and biochemical detergents to wash polysulphone membranes using in milk ultrafiltration needs a multidisciplinary investigation. by increasing use of these membranes in food processing, washing and recovery of initial permeate flux, in order to use for a longer time from this technology, has much importance. in this research, influence of chemical detergents including e...

to evaluate the effect of different levels of drought stress on some physiological parameters in strawberry, potted experiment involing strawberry cultivars  ‘marak٫ , ‘camarosa٫ and ‘gaviota٫ was conducted during summer 2009. the experiment consisted of three drought stress levels in three replications. the experimental arrangement was a factorial one, based upon a randomized complete block de...

Gas-permeable membrane technology is useful to recover ammonia (NH3) from liquid manures. In this study, phosphorus (P) recovery via MgCl2 precipitation was enhanced by combining it with NH3 recovery through gas-permeable membranes. Anaerobically digested swine wastewater containing approximately 2300 mg NH4+-N L-1 and 450 mg P L-1 was treated using submerged membranes plus low-rate aeration to...
