1. This study examined the effects of altering nitric oxide levels with sodium nitroprusside or L-arginine in rat hearts stored hypothermically. 2. Hearts were microperfused at 4 °C for 24 h with a modified Krebs–Henseleit buffer (KHB) that contained either sodium nitroprusside, L-arginine, L-arginine methyl ester or dexamethasone. 3. After hypothermic storage, hearts were rewarmed to 37 °C wit...

Catalases are efficient scavengers of H2O2 and protect cells against H2O2 stress. Examination of the H2O2 stimulon in Saccharomyces cerevisiae revealed that the cytosolic catalase T (Ctt1) protein level increases 15-fold on H2O2 challenge in synthetic complete media although previous work revealed that deletion of the CCT1 or CTA1 genes (encoding peroxisomal/mitochondrial catalase A) does not i...

Microvesicles (MVs) are carriers of molecular and oncogenic signatures present in subsets of tumor cells and tumor-associated stroma, and a focus of cancer research. Although methods to detect MVs are mature, we were concerned that the buffer used could lead to false results when quantitating MVs by flow cytometry. In this work,we detected MVs by flow cytometry withthree different solutions: wa...

Abalone (Haliotis discus hannai) is a widely consumed seafood in Asian countries. Rich protein, abalone for refreshment, pregnancy care, and vitality. Although many studies have found that protein has beneficial effects, the efficiency of extraction method rarely been studied. Therefore, this study aimed to examine effects various factors extraction, including buffer, sonication, salt (NaCl) co...

microencapsulation has become a common technique in the production of controlled release dosage forms. many results have been reported, concerning the use of alginate beads as controlled release drug formulations. alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

in this study, aggregation behavior of a water soluble cationic metalloporphyrin, meso-tetrakis (2,3,5,6-tetrafluoro-n,n´,n´´-trimethyl ammonium phenyl) porphyrin nickel(ii) [ni(ii)(tf4tmapp)]4+ is investigated in 5 mm aqueous phosphate buffer of ph 7.0 at 25.0 °c and various ionic strengths using optical absorption and resonance light scattering spectroscopic methods. the results suggest that ...

a r t i c l e i n f o Keywords: ZnO nanoparticulates Phosphate Al activation Capacitor Electrochemical power sources We report on an innovative membrane-free aluminum/phosphate cell based on the activation of aluminum (Al) as anodic material using ZnO nanocrystal in phosphate rich electrolyte that is capable of generating sufficient power to power a light-emitting diode (LED), selected as a mod...
