Glutathione-S-transferases (GSTs) play an important role in the detoxification of chemicals that may lead to mutagenic or cytotoxic effects. In this study, we aimed to find the effect of aqueous, methanol and ethanol extracts of both Ephedra aphylla and Ephedra foeminea on the activity of the purified sheep liver GST at the following different conc...

The aim of the present study was to investigate some biological activities of Aizoon hispanicum, Heliotropim maris-mourtui and Polygonum arenarium which are wildly growing in Palestine. The first part of the current research was to find out the effect of the screened plant extracts on hepatic GSTs spectrophotometrically. The obtained results reveal...

The concern toward using herbs around the world for the treatment of infectious diseases is increased during this century. Based on that, the following conducted experiment was performed to detect the effectiveness of using ethanol and aqueous extracts from Satureja thymbra L. (Lamiaceae) that is growing wild in Palestine. The bioactivity of both a...

Three new tetradentate NNNS Schiff bases (L1–L3) derived from 2-(piperidin-4-yl)ethanamine were prepared in high yields. UV–Visible and FTIR spectroscopy were used to monitor the dehydration reaction between 2-(piperidin-4-yl)ethanamine and the corresponding aldehydes. Structures of the derived Schiff bases were deduced by 1H and 13C NMR, FTIR, UV–...

The haemostatic efficacy of different extract types of Satureja thymbra L., Thymbra spicata L. (Lamiaceae) and Verbascum fruticulosum Post. (Scrophulariaceae) was evaluated in this study via the Prothrombin time (PT) and Activated partial thromboplastin time (aPTT) analysis. Aqueous, methanol and ethanol extracts of the examined plant species leave...

Camel milk is an important nutritional source that historically been used in the treatment of cancer. Therefore, the main aim of the present study is to determine the in vitro anticancer effect of both camel milk and whey against cervix cancer (HeLa) cells. To perform that, skimmed milk as well as whey immunoglobulins concentrate samples were prepa...

The aim of this study was to find out the effect of camel whey immunoglobulins on the activity of glutathione-s-transferases (GST). The effect of camel whey immunoglobulins was tested at variable conditions including their concentration effect, their pre-incubation effect and the effect of pH and temperature on their activity. Moreover, the effect...

Nature has been recognized as a rich source of medicinal compounds for many years. The herb Salvia (Lamiaceae) is distributed all over West Bank different locations. In spite of the presence of several species of Salvia, only S. fruticosa has long been used locally by the native people to relief intestinal pains and diarrhea. Previous literature di...

Due to the emergence of antibiotic resistant pathogens, plants are being an excellent alternate to fight the further spread of multidrug resistant microorganisms. In this study, six plant species grown wildly in Palestine were used to determine their efficacy against multidrug resistant clinical isolate of Escherichia coli. The dried areal parts of...

The effect of alkyl substitution on the chemical and biological properties of Cu(II) diamine compounds was studied by carefully synthesizing two asymmetrical diamine/copper(II) nitrate salt complexes. The unsubstituted complex A and ethyl substituted complex B were synthesized from hydrated copper nitrate salt and the appropriate diamine ligands an...
Conference Paper
Introduction Bioactive ingredients of camel milk and plant extracts have gained significant attention of scientists for their medicinal values. Therefore, the present study was performed to evaluate the antibacterial potential of camel whey and Rosmarinus officinalis extracts. In addition to their effect on the activity of Glutathione-S- transferas...

Based on the importance of herbal plants in medicine, this study was conducted to evaluate the antibacterial efficacy of aqueous, ethanol and methanol extracts of Thymbra spicata, Nepeta curviflora, and Verbascum fruticulosum against two clinical isolates (I and II) of the gram positive methicillin resistant Staphylococcus aureus (MRSA). Agar well...

Aim: As there is little data available on the validity of wild plants use in Palestine for blood disorders, the aim of this study was to determine the anticoagulant properties of Urtica urens, Parietaria judica, Satureja thymbra, Thymbra spicata, Teucrium creticum, Verbascum fruticulosum, Lupinus pilosus, Paronychia argentea, and Ruta chalepensis....
Conference Paper
Purpose: The main objective of this study was to evaluate the antibacterial potential of ethanol extracts from Ballota undulata and Ruta chalepensis in combination with camel milk and camel whey proteins. Methods and Materials: Protein contents of milk and whey samples were fractionated by SDS-PAGE. Agar disk diffusion method was used to examine t...
Conference Paper
Based on the importance of herbal plants in medicine as antibacterial agents, this study was conducted to evaluate the antibacterial efficacy of aqueous, ethanol and methanol extracts of Thymbra spicata, Nepeta curviflora, and Verbascum fruticulosum against methicillin resistant Staphylococcus aureus (MRSA).

Conference Paper
The recognition of what nature can offer was based on the historical use of medicinal plants for various diseases. This has led to a global interest in the study of medicinal plants and their traditional uses are increasing the scientific validation of the therapeutic potential of medicinal plants. The herb Salvia is wildly distributed throughout d...
Conference Paper
Background: Salmonella typhimurium is the primary causative agent of salmonellosis in animals and humans. Many methods are used to treat salmonellosis including our previous study in which orally administrated camel milk to infected mice reduced their deaths and reduce bacterial load in their blood, livers and spleens. Objectives: To investigate th...

Streptococcus pneumoniae is one of the most important bacterial pathogens that affect respiratory system. The occurrence of multidrug-resistant strains of S. pneumoniae necessitates the discovery of new classes of anti-pneumonia drugs. As some of the medicinal plants and their extracts have antibacterial activity, we aimed to investigate the antiba...

Camelidae have a unique humoral immune response, as they are the only known mammals that possess two different types of IgG antibodies. One type of these antibodies is IgG1 conventional antibodies which is composed of two heavy chains and two light chains. The other type is unusual as these antibodies lack the light chains and so called heavy chain...
Conference Paper
A breakthrough in immunity has occurred by the discovery of a new type of antibodies which are devoid of the light chains in family Camelidae. They were found in Camelus dromedarius serum as they comprise approximately 50% of total serum antibodies (Hamers-Casterman et al., 1993). They also were found in milk, their high stability allows them to pa...
