Di(2-ethylhexyl) phthalate (DEHP) is an environmental pollutant that is widely used in medical and consumer products. An epidemiological study has suggested that a large daily intake of DEHP from phthalate-contaminated food may be a risk factor for liver dysfunction. Long-term exposure to DEHP i...

In vitro fertilization (IVF) is one of the most important treatments of infertility to provide a chance of conceiving. In IVF treatment, sperm are washed and motile sperm are isolated with sperm washing media (SWM) for the purpose of fertilization; fertilized ova are then incubated for a maximum...

In the present study, we have investigated the endocrine disruptive effects of waterborne di-(2-ethylhexyl) phthalate (DEHP: 0 (control), 10, 100, 200 and 400 μg/L) on juvenile Clarias gariepinus by analyzing transcript patterns for hepatic vitellogenin (vtg), estrogen receptor-α (er-α), arom...

Mono-2-ethylhexyl phthalate (MEHP) is a major bioactive metabolite in the widely used industrial plasticizer diethylhexyl phthalate (DEHP) that has been found to be toxic to the liver. The aim of this study is to determine whether MEHP exposure can change the expression of fatty acid metabolism-...

The aim of this work was to develop new materials employing polymeric nanofibers modified with an organic extractant for the extraction of metals. For this purpose, nylon-6 nanofibers were modified with di-(2-ethylhexyl) phosphoric acid (DEHPA) for use in the selective extraction of zinc and nic...

Di-(2-ethylhexyl) phthalate (DEHP) possesses the potential to interfere with the male reproductive endocrine system in mammals; however, its reproductive toxicity in male zebrafish and associated epigenetic studies have not been explored. In this study, three-month-old male zebrafish were expose...

Soil co-contamination of potentially toxic elements (PTEs) and phthalate esters has become prominent due to its potential adverse effect on human food supply. There is limited information on using wood- and animal-derived biochars for the remediation of co-contaminated soils. Therefore, a pot ex...

The results of a pyrolysis-gas chromatography/mass spectrometry (py-GC/MS) study of several poly(ether urethane), poly(urea), and poly(ether urethane-urea) materials are reported. Mechanisms for the formation of pyrolytic degradation products are proposed. These can be used to differentiate betw...

The (CO2 + 2-ethoxyethyl acetate) and (CO2 + 2-(2-ethoxyethoxy)ethyl acetate) systems at 313.2, 333.2, 353.2, 373.2 and 393.2 K as well as pressures up to 20.59 MPa have been investigated using variable-volume high pressure view cell by static-type. The solubility curve of 2-ethoxyethyl acetate ...

Stimulus-responsive wormlike micelles (WLMs) have received extensive attention in the past decade. In this article, we report dual stimuli-responsive WLMs based on a single-responsive azobenzene surfactant (C4AzoC6N) and a commercially available organic slat, sodium azophenol (AzoONa). Fast and ...

A modified Coomassie Brilliant Blue G 250 staining method for detecting chitinolytic enzymes in chitin-containing polyacrylamide gel electrophoresis (PAGE) is presented. The staining formed achromatic zones at the locations of the migrated enzyme. Using Streptomyces griseus chitinase, we have de...

Commercial samples of Coomassie Brilliant Blue G-250 (CBB) were not pure enough to give reliable results when used as indicator of amine content in biological material. The polar and apolar impurities produce unacceptable biases in the results. Counter current chromatography (CCC) was used to pu...

Coomassie brilliant blue G-250 (CB) is the dye used frequently in the Bradford assay for protein concentration determination. In this study, we investigated how the solvent polarity and viscosity affect the CB absorption and fluorescence spectra and apply this understanding to investigate the bi...

The present work was carried out to evaluate the removal of Coomassie brilliant blue dye by adsorption onto a magnetized activated carbon nanocomposite (MNSA) prepared from Nigella sativa L. (NS) waste. Different techniques, including infrared spectroscopy, scanning electron microscopy, and nitr...

In this study, SBA-15 mesoporous silica was synthesized and functionalized with cross-linked polyacrylic acid and used to remove Reactive Orange 16 (RO16) from aqueous media. X-ray diffraction (XRD), filed emission scanning electron microscope (FE-SEM), fourier transform infrared spectrometer (F...

A laboratory scale Rotating Drum Biological Contactor (RDBC; drum length × diameter: 255 × 130 mm) filled by randomly arranged particulate carriers with mycelium of the white rot fungus Irpex lacteus was tested for Reactive Orange 16 (RO16) decolorization. Five mycelium carriers were pre-scree...

Sorbents for environmental remediation, based on Advanced Materials, have attracted research interest because of their better selectivity, reusability and resolution of disposal problems at end-of-life, relative to conventional activated carbon based sorbents. The adsorption behavior of non-calc...

The study aimed to determine the fatty acid composition, vitamin E content of meat from light lambs in relation to slaughtering season (winter and spring) and age (45 and 60 days). In each season, twenty lambs were subdivided into two groups corresponding to the experimental ages. All lambs rece...

Stereoselective total synthesis of aspinolides B, E and J, naturally occurring 10-membered lactones, were accomplished by divergent strategies starting from the commercially available 2,3-O-isopropylidene-d-ribose and methyl d-lactate. The synthesis features rapid access to the both key fragment...

Caffeic acid phenethyl ester (CAPE) is a natural compound with anticancer activities but has low water solubility. In this work, sucrose fatty acid ester (SFAE) was used to nanoencapsulate CAPE in aqueous propylene glycol (PG) with a temperature-cycle method by heating at 90 °C for 20 min and c...
