Antibacterial and Antifungal Sesquiterpenoids from Aerial Parts of .

Two new sesquiterpenoids belonging to the guaiane, 4α,9α,10α-trihydroxyguaia-11(13)en-12,6α-olide (), and germacrane, 9β-hydroxyparthenolide-9--β-D-glucopyranoside (), classes have been isolated from the leaves of the Saudi medicinal plant along with seven known compounds (-). The structures of the new metabolites were elucidated by spectroscopic analysis, including one-dimensional (1D) and two-dimensional (2D) Nuclear Magnetic Resonance (NMR) and high-resolution electrospray ionization mass spectrometry (HR-ESIMS). The antimicrobial properties of - were screened against seven different pathogenic microbes, and compounds - showed a potent antifungal activity.

Effect of Curcumin on Iron Toxicity and Bacterial Infection in Catfish ().

Background And Objective: Iron is an essential element that involved in many vital physiological functions in fish, while excess iron concentration causes many toxic effects. Curcumin is a natural popular spice that used as a dietary supplementation and has iron chelating properties. This study was conducted to evaluate the effect of curcumin on iron toxicity in catfish (Clarias gariepinus).

Chemical composition and antimicrobial and cytotoxic activities of Antidesm abunius L.

Chemical Composition and Antimicrobial Activities of Essential Oils of Some Coniferous Plants Cultivated in Egypt.

Family Cupressaceae is the largest coniferous plant family. Essential oils of many species belonging to family Cupressaceae are known to have several biological activities specially antimicrobial activity. The essential oils from aerial parts of Torr.

Circulating microRNAs, miR-92a, miR-100 and miR-143, as non-invasive biomarkers for bladder cancer diagnosis.

The application of microRNAs (miRNAs) as potential biomarkers and therapy targets has been widely investigated in many kinds of cancers. Recent advantages of serum miRNAs open a new realm of possibilities for non-invasive diagnosis and prognosis of bladder cancer (BC). The aim of our study was to identify plasma miR-92a, miR-100 and miR-143 expression signatures in patients with BC to introduce new markers for establishing BC diagnosis and prognosis.

Cytotoxicity Assessment of Six Different Extracts of Abelia triflora leaves on A-549 Human Lung Adenocarcinoma Cells.

The present investigation was designed to assess the anticancer activity of six different leaf extracts (ethyl acetate, methanol, chloroform, petroleum ether, n-butanol, and water soluble) of Abelia triflora on A-549 human lung adenocarcinoma epithelial cells. A-549 cells were exposed to 10-1000 μg/ml concentrations of the leaf extracts of A. triflorafor 24 h and then percentage cell viability was assessed by 3-(4,5-dimethylthiazol-2yl)-2,5-biphenyl tetrazolium bromide (MTT) assay.

Chemical composition and biological activity of extracts from Salvia bicolor Desf. growing in Egypt.

A petroleum ether extract (PEE) and a methanolic extract (ME) of aerial parts of Salvia bicolor Desf were prepared, and their chemical compositions and antioxidant, anti-inflammatory, analgesic and antimicrobial activities were evaluated. GC/MS analysis of the PEE revealed the presence of 20 compounds in the unsaponifiable matter, among which β-sitosterol and β-amyrin (constituting 24.75% and 15.

Skeletal ossification impairment in Nile Tilapia (Oreochromis niloticus) after exposure to lead acetate.

Heavy metal pollution represents a serious problem facing many of the aquatic organisms. Lead is one of the most toxic elements found in many industrial effluents which are metabolized inside bodies and can cause skeletal deformities by impairing developmental processes and bone formation. This study was undertaken to determine the LC50 of Pb-acetate and detect the effect of 1/10 LC50 exposure on fingerlings of Nile Tilapia (Oreochromis niloticus).
