Fungal Adenylyl Cyclase Integrates CO2 Sensing with cAMP Signaling and Virulence Summary The ascomycete Candida albicans is the most common fungal pathogen in immunocompromised patients [1]. Its ability to change morphology, from yeast to filamentous forms, in response to host environmental cues is impo...
Co-immobilized silica matrices containing dual fluorophores like Fluorescien and phenosafranine have been used for pH determination in water samples by Gao et al.27 Ke et al. described synthesis of FITC-BSA/Gold nanoclusters (AuNCs) which act as single wavelength excitation based indicator (I525/...
Method for the Determination of PCB Congeners and Chlorinated Pesticides in Human Blood Serum Determination of organochlorin e compounds (OCCs) in human blood has engaged the attention of many analytical chemists for many years (Burse et al 1990; Gi... SS Atuma,M Aune - 《Bulletin of Environ...
This procedure of emulsification/demulsification was repeated five times and the ability to break the newly formed emulsion through switching its pH, in addition to the long-term stability of the reformed emulsion after each cycle, were monitored. 3. Results and discussion One of the key factors ...
Manipulations done with metal ion solutions can influence the accuracy of a determination. During a manipulation, when a non-homogeneous solution in a non-equilibrium state is dealt with, polynuclear hydroxide compounds and/or a hydroxide precipitate may be formed, which generally do not immediately ...
The way these parameters affect the accuracy and the precision of the results is examined. It is inferred that pH-static titrations can be competitive with traditional titration procedures, particularly for the determination of the effective strength of secondary standard solutions of strong bases. ...
Benzofuran 326 also contains the styrene substructure, but there are few examples of its polymerization. Poly(2,3-benzofuran) films were synthesized by anodic oxidation on stainless steel in the presence of boron trifluoride etherate. The films had good thermal stability and conductivity of 10−...
DETERMINATION OF THE CONSTANTS OF THE HENDERSON-HASSELBALCH EQUATION, (alpha)CO2 AND pKa, IN SEA TURTLE PLASMA Hydration of CO2 yields HCO3- via the reaction: CO2 + H2O = H2CO3 = HCO3- + H+ = CO32- + 2H+. (1) Acid-base physiologists traditionally simplify the reacti... EK Stabenau...
