Photocatalytic degradation of Ibuprofen (IBU) which is an anti-inflammatory drug was investigated in aqueous solution by Co-doped TiO2 and bare synthesized reflux route. The prepared catalyst powders were fully characterized using X-ray diffraction (XRD), FT-IR spectroscopy, scanning electron microscopy (SEM), BET surface areas, Fluorescence Spectroscopy (XRF), dynamic light scattering (DLS). E...

The Pacific white shrimp, Litopenaeus vannamei, acclimated to 30 ppt salinity, was transferred to either low (15 and 5 ppt), or high (45 ppt) salinity for 7 days. Hemolymph osmolality, branchial carbonic anhydrase activity, and total ninhydrin-positive substances (TNPS) in abdominal muscle were then measured for each condition. Hemolymph osmotic concentration was regulated slightly below ambien...

The evolutionary origin and maintenance of discontinuous gas exchange (DGE) in tracheate arthropods are poorly understood and highly controversial. We investigated prioritization of abiotic factors in the gas exchange control cascade by examining oxygen, water and haemolymph pH regulation in the grasshopper Paracinema tricolor. Using a full-factorial design, grasshoppers were acclimated to hypo...

In this research, Carbon-doped TiO2 nano-photocatalyst is synthesized via sol-gel technique and photo-catalytic degradation of phenol has been studied under ultraviolet and visible light irradiation in a fluidized bed reactor. Various techniques are used to characterize TiO2 nano-photocatalyst such as X-Ray Diffraction, Fourier transform infrared spectroscopy,  Energy Disp...

Chlorophyll fluorescence (Chf) emission allows estimating the photosynthetic activity of vegetation -a key parameter for the carbon cycle modelsin a quite direct way. However, measuring Chf is difficult because it represents a small fraction of the radiance to be measured by the sensor. This paper analyzes the relationship between the solar induced Chf emission and the photosynthetically active...

BACKGROUND In the diagnosis of early-stage lung cancer photosensitizer-enhanced fluorescence bronchoscopy with inhaled 5-aminolevolinic acid (5-ALA) increases sensitivity when compared to white-light bronchoscopy. This investigation was to evaluate the in vivo tissue pharmacokinetics of inhaled 5-ALA within the bronchial mucosa in order to define the time optimum for its application prior to br...

In this study, the response to salt stress was evaluated in ex vitro acclimated date palm plants, regenerated from culture multiplication. The eighteen-month-old, were irrigated with 0 (control), 150, 300 or 450 mM NaCl solutions (high very high-water salinity). Photosynthesis parameters and antioxidant compounds determined at end of experiment leaves. At 150 NaCl, net CO2 assimilation rate int...

Plant Materials and Growth Conditions The wild-type (WT) Arabidopsis seedlings used in this study is Columbia-0 ecotype. All ethylene mutants [1, 2], PIF3OX [3], iE/qm [4] , pif1 pif3 pif4 pif5 and pif3-3 [5] were lab stocked. pif1 (SALK_131872C) [6], pif3 (SALK_081927C) [2], pif3-1 (SALK_030753) [7], pif4 (SALK_140393C), pif5 (SALK_087012C) [8], erf1 (CS481507), erf6 (SALK_030723), erf11 (SALK...

The role of cholesterol in the thermal adaptation of biological membranes is explored. Physical and chemical responses of membranes to acclimation temperature were evaluated using plasma membrane domains (basolateral and brush border) prepared from intestinal epithelia of 5- and 20 °C-acclimated rainbow trout (Oncorhynchus mykiss). Basolateral membranes (BLMs) exhibit perfect homeoviscous e...
