The aim of this study was to determine the activity of β-galactosidase in the crude extracts of Pleurotus ostreatus in the presence and absence of various heavy metals. β-galactosidase (EC 3.2.1.23), is a hydrolase enzyme which helps in the hydrolysis of lactose into monosaccharides. Characterization of β-galactosidase from Pleurotus ostreatus was...

β-galactosidase (EC 3.2.1.23) is important in the formation of a medicinal plant Artemisia judaica (al-ba’atharan) aroma. The crude plant extracts of Artemisia judaica were used to characterize the enzyme in the term of pH, temperature, enzyme kinetic and effects of some heavy metals on its activity. The enzyme activity was measured by its ability...

The proteolytic activity in crude extracts of pumpkin and pomegranate fruits was measured with albumin, egg albumin and casein as substrates. The kinetic parameters (Vmax) and (Km) were investigated using the different substrates and revealed a broad specificity from both samples. Both crude extracts appeared to be active over a wide pH range with...

The proPO system is an important humoral immune response among invertebrates. It has been found in many species, including the bivalves, C. gigas, Mytilusedulis,Pernaviridis andPernaperna(Coles and Pipe 1994; Asokan et al. 1997;Hellio et al. 2007). ProPO is present in the plasma or haemocyte compartments of hemolymph, or in both depending on the sp...

Cumin (Cuminum cyminum L.) and caraway (Carum carvi L.) are aromatic plants within the Apiaceae family. They have a variety of purposes and demonstrate antioxidant and antimicrobial properties. Methanolic and acetonic seed extracts of both plants were able to neutralize free radicals and carried antioxidant properties. Both seed extracts were able...

Liposomes are often used as a carrier to improve the therapeutic activity and safety of drugs. The lipid composition of liposomes plays an important role in determining the behavior of liposomes in phases. In this study, the phospholipid and alkylresorcinol content in crude acetone extracts of seeds of Canna indica L., Cucumis melo L. and Prunus ar...
Article
The effects of alkyIresorcinols (ARs) obtained from the acetonic extract of whole-wheat grains (Triticum sativum) on the stability, encapsulation efficiency and permeability of liposomes was investigated in this study. This extract could form vesicles alone (AR liposomes) as well as incorporation of the extracted ARs with phosphatidylcholine (PC) (...

Liposomes made from phosphatidylcholine (PC) or PC-fatty acid ester mixtures have been shown to induce an activation of the respiratory burst in human blood monocytes and alveolar macrophages (AM). Incorporation of 1,2-diacylglycerol or arachidonic acid into PC liposomes significantly enhanced the effect. In the case of AM, the effect of PC liposom...

It is shown that in comparison with phorbol myristate and the calcium ionophore A23187, phosphatidylcholine liposomes less effectively induce the formation of superoxide radical in human peripheral blood monocytes. The efficiency of liposomes moderately increase after incorporation of 1,2-diacylglycerol and gangliosides, but not of esterified fatty...

1. Synthesis of new natural transporting carriers (Ghost RBCs) of enzymes or other biomolecules. 2. To prove the validity of the paradigm that Ghost cells can be used as a carrier for drug, enzyme, and biomolecules. The stability and percentage of entrapment of the loaded enzyme and biomolecules will be determined. The size and morphology of the loaded Ghost RBCs will be investigated too. 3. Microscopic studies of the interaction of Ghost RBCs with human neutrophils. 4. Using this carrier system for in vivo anti-inflammatory or topical analgesic activities in Rats.
