The correlation of TNF alpha levels with acute phase proteins in acute Toxoplasma gondii infection in mice
(Academic Press Inc Elsevier Science, 2022)Acute Toxoplasma gondii infections can influence the liver as well as other organs. Many cytokines and proteins play a role in the acute response against infection. Tumor necrosis factor alpha (TNF alpha) is a cytokine ... -
East Asian-North American disjunctions and phylogenetic relationships within subtribe Nepetinae (Lamiaceae)
(Academic Press Inc Elsevier Science, 2023)Biogeographic disjunctions, including intercontinental disjunctions, are frequent across plant lineages and have been of considerable interest to biologists for centuries. Their study has been reinvigorated by molecular ... -
The effects of gastric juice acidity on bioaccessibility of some elements in selected foods
(Academic Press Inc Elsevier Science, 2020)The pH value of gastric juice changes between 1.5 and 3.5 in healthy people but the upper pH range can be as higher as 7 in the presence of a gastric ulcer or different gastric cancers. The effects of the acidity of gastric ... -
Electrokinetic properties of sepiolite suspensions in different electrolyte media
(Academic Press Inc Elsevier Science, 2005)The present paper deals with the electrokinetic characterization of sepiolite. A series of systematic zeta potential measurements have been carried out to determine the isoelectric point (iep) and potential-determining ... -
Ellagic acid plays an important role in enhancing productive performance and alleviating oxidative stress, apoptosis in laying quail exposed to lead toxicity
(Academic Press Inc Elsevier Science, 2021)Lead (Pb) is one of the most toxic heavy metal environmental pollutants due to its widespread use of the industry and it is a harmful substance for human and animal health. This study was conducted to investigate the ... -
In vitro inhibition of the carbonic anhydrase from saanen goat (Capra hircus) with pesticides
(Academic Press Inc Elsevier Science, 2007)This study was conducted to determine the in vitro effects of four commonly used pesticides (Nuarimol(Tm), Fenarimol(TM), Parathionmethyl(Tm) and 2,4-D-TM) on erythrocyte carbonic anhydrase (CA) activity from Saanen goats ... -
Modeling of vapor sorption in polymeric film studied by surface plasmon resonance spectroscopy
(Academic Press Inc Elsevier Science, 2008)Sorption process by surface plasmon resonance (SPR) was studied by exposing polymeric film made from anthracene labeled poly(methyl methacrylate) (An-PMMA) chains to various concentrations of saturated chloroform vapor. ... -
