Objective: Cape gooseberry (Physalis peruviana L.) belongs to the Solanaceae family.
Physalis has many medicinal properties however, the beneficial effect of physalis in protecting against
neurotoxins has not yet been evaluated. This experimental study investigated the protective effect of
physalis juice against the oxidative damage induced by carbon tetrachloride (CCl4) in the rat brain.
Methods: The degrees of protection by physalis in brain tissues were evaluated by determining the brain levels of lipid

A series of substituted pyridinium candidates 2–11 were synthesized and tested as antimicrobial activities by using 4,9-di(3-methoxyphenyl)-2,7-dioxo-1,2,5,6,7,10-hexahydropyrido[2,3-g]quinoline-3,8-dicarbonitrile (1) as starting material. Treatment of cyanopyridione 1 with ethyl chloroacetate afforded bis-ethyl ester derivative 2, which was fused with anthranilic acid to give oxazin-4-on-3,8-dicarbonitrile derivative 3.

In the process of profiling the secondary metabolites of actinobacteria isolated from the Saudi coastal habitats for production of antibiotics and anti-cancer drugs, the cultures of strain WH1 that was identified as Streptomyces heliomycini exhibited strong antibacterial activity against Staphylococcus aureus. By means of MS and NMR techniques, the active 
compounds were characterized as actinomycins X0β, X2 and D, respectively. The research on the productivity of this strain for actinomycins revealed that the highest production of .

Host related variations in helminth egg and coccidian oocyst counts were compared
between a naturally infected endemic population of Farasan gazelle and domestic goats on the
Farasan Islands, Saudi Arabia in April 2009. Both bovid species inhabit and browse in the same
area but no cross-infection could be detected. The prevalence and mean intensity quantified as
the number of eggs and oocysts per gram of faeces were taken as a measure of parasite burdens.
Host related differences in prevalence values of Eimeria spp. were significantly higher in domestic
