Inhibitory effect of some plant extracts on clinical isolates of Staphylococcus aureus
Accumulating data have been dramatically increasing on multiple drug resistantStaphylococcus aureus isolates that are incriminated in nosocomial and community acquired infections causing high mortality and morbidity. Accordingly, 70 resistant isolates were collected from King Fahad General Hospital and National Guard Hospital, Jeddah, Saudi Arabia in an attempt to find alternative antimicrobial substances from...

STK1, a MAP kinase gene from Setosphaeria turcica, confers preferable tolerance to sodium salt stress
Setosphaeria turcica, a serious fungal plant pathogen that causes northern corn leaf blight, is a filamentous, heterothallic ascomycete. STK1 gene, cloned from S. turcica, encodes a mitogen-activated protein kinase (MAPK) that is homologous to Hog1 inSaccharomyces cerevisiae and other MAP kinases related to osmoregulation in filamentous fungi. Its encoded protein, Stk1, contains all the conserved...

Ultrasound assisted extraction for analysis of total phenolic content and antioxidant activity of medicinal plants
In the present study, Bupleurum chinense, Isatis indigotica Fort., Kadsura coccinea,Notopterygium incisum and Rhizoma Anemarrhenae were investigated for total phenolic contents (TPC) in water, ethanol and methanol solvent. The antioxidant activities of extracts were determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activities (DPPH%) and reducing power (RP) assay....

Effect of microencapsulation plus resistant starch on survival of Lactobacillus casei and Bifidobacterium bifidum in mayonnaise sauce
Two types of probiotics (Lactobacillus casei and Bifidobacterium bifidum) were added to mayonnaise sauce as either free cells or encapsulated with resistant starch. The survival of L. casei and B. bifidum was evaluated during the product storage for 30 days at 4°C. The viability of B. bifidum cells disappeared in the free state after 10 days; however, free L....

Effects of berberine on the proliferation and the protein expression of Bcl-2, Bax on human gastric carcinoma SGC-7901 cells
Berberine (BBR) is widely used to treat diarrhea and inflammation, and its antitumor activity has been vastly reported recently. However, its antitumor mechanism remained unclear. In the present study, the effects of Berberine on human gastric cancer SGC-7901 cells in vitro and its mechanism were investigated. Cisplatin (DDP) was used as positive control. The inhibition of drugs on SGC-7901 was evaluated...

Screening of natural extracts for their antibacterial activity against different enteric pathogens isolated from soil, water and rotten fruit samples
Different bacterial strains were isolated from soil, water and rotten fruit samples, and biochemically characterized as Shigella, Pseudomonas, Escherichia coli, Klebsiella andProteus. Unhygienic environment (for example, contaminated food, water and air) are the most common habitats of these pathogens. Mostly, all are involved in endemic breakouts causing urinary tract and gastro-intestinal...
