objectives: osteoblasts are the most important cells in the osseointegration process. despite years of study on dental implants, limited studies have discussed the effect of saliva on the adhesion process of osteoblasts to implant surfaces. the aim of this in vitro study was to evaluate the effect of saliva on morphology and differentiation of osteoblasts attached to implant surfaces. materials...

backgrounds and aims: the purpose of this study was to examine the effects of potassium, sodium and zinc metal ions on ammonium sulfate fraction of acid phosphatase activity of orange fruit. materials and methods: acid phosphatase was extracted and purified from orange fruit and then various samples as well as a control sample were prepared in vitro. in addition to substrates, ions of potassium...

water and soil salinity are two of the most important limiting factors in crop production. phosphatase enzymes are widely found in plants. phosphatase enzymes are responsible for de-phosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted using two bread wheat cultivars, namely, iniya66 and ghods along with application of different nacl p...

Background: Hodgkin’s disease (HD) is a neoplastic disease originating in lymphoid tissue, which spreads to lymphoid structures and ultimately nonlymphoid tissues. Lactate Dehydrogenase and Alkaline Phosphatase are increased in blood following membrane cell damage. The aim of this study was to compare Lactate Dehydrogenase and Alkaline Phosphatase levels in children in different stages of Hodg...

Bu çalışmada Kurşun (Pb)’un sublethal derişimlerinin ve Pb + NTA (Nitrilotriasetik asit) karışımının, 7 21 gün süreyle, etkisine bırakılan tatlısu balığı O. niloticus’un kas karaciğer dokularındaki bazı enzim aktiviteleri oksidatif stres düzeyi incelenmiştir. Parametreler, otoanalizatör cihazlarla ölçülmüştür. Elde edilen veriler neticesinde; dokusunda total oksidan (TOS), indeksi (OSİ) düzeyle...

The main role of cumulus cells (CC) is to provide nutritious materials for developing oocytes. Follicular fluid (FF) contains the enzyme acid phosphatase, which plays a role in ovulation and fertilization of oocyte. The objective of this prospective study was to evaluate the levels of acid phosphatase in FF and the rate of apoptosis in CC of fertilized and unfertilized oocytes in intracytoplasm...

Background: Heavy metals such as cadmium (Cd2+) are natural components of the Earth's crust which can not be degraded or destroyed. Industrial, mining and agricultural activities, particularly the excessive use of phosphate fertilizers, have led to high levels of cadmium contamination at many locations worldwide. Some toxic effects of cadmium are due to its inhibition of various enzyme sys...

Alkalin-reduced water (ARW) is known to exert several anti-cancer effects, as well as to scavenge reactive oxygen species (ROS) and reduce blood-glucose levels. This study was performed in order to determine the effects of ARW on the control of spontaneous diabetes in Otsuka Long-Evans Tokushima Fatty (OLETF) rats. We assigned 16 male OLETF rats (4 wk) to two groups: an experimental group, whic...

phosphorus (p) is one of the most vital elements for all living organisms which acts as aconstituent of essential biomolecules such as nucleic acids, phospholipids, and phosphosugars,and as a major contributor to almost all metabolic reactions including photosynthesis,respiration, and energy delivery. it is one of the most needed nutrients for plant growth anddevelopment. despite high levels of...
