In this contribution, the conservation status assessment of three vascular plants are presented according to IUCN categories and criteria. It includes Oryza rhizomatis D.A.Vaughan Saxifraga facchinii W.D.J.Koch at a global level Helianthemum caput-felis Boiss. regional level.

Aprotinin has been used widely in surgery as an anti-bleeding agent but is associated with a number of side effects. We report that textilinin-1, a serine protease inhibitor from Pseudonaja textilis venom with sequence relatedness to aprotinin, is a potent but reversible plasmin inhibitor and has a narrower range of protease inhibition compared to aprotinin. Like aprotinin, textilinin-1 at 5 mi...

Two lethal proteins, which specifically bind to the nAChR from Torpedo californica, were isolated from the venom of Pseudonaja textilis, the common brown snake from Australia. The isolated proteins have masses of 6236 and 6345 Da and are structurally related to short-chain neurotoxins from other elapids. Six cDNAs encoding isoforms of related neurotoxins were cloned using the RT-PCR of the veno...

The Peiligang Culture (9000-7000 cal. yr BP) in the Middle Yellow River region, North China, has long been considered representative of millet farming. It is still unclear, however, if broomcorn millet or foxtail millet was the first species domesticated during the Peiligang Culture. Furthermore, it is also unknown whether millet was cultivated singly or together with rice at the same period. I...

The stimulatory effect of Zataria multiflora Boiss (Labiatae) and carvacrol on β-adrenoceptors was examined on guinea pig trachea. The effects of three concentrations of aqueous-ethanolic extract, carvacrol, and propranolol (β-receptor antagonist) on β-adrenoceptors were tested in nonincubated (group 1, n = 8) and incubated tracheal chains with 1 μM chlorpheniramine (histamine H1 receptor antag...

BACKGROUND AND OBJECTIVES Acinetobacter spp. are important causes of nosocomial infections. They possess various antibiotic resistance mechanisms including extended spectrum beta lactamases (ESBLs). The aim of this study was to determine antibiotic resistance profile of Acinetobacter clinical isolates especially among ESBL-producing strains and to investigate the antimicrobial effects of oleo-g...

OBJECTIVES Ferula gummosa Boiss is native to central Asia. This plant has traditionally been used in the treatment of many diseases. The antihypoxic and antioxidant activities of Ferula gummosa roots were investigated. MATERIAL AND METHODS 1,1-diphenyl-2-picryl hydrazyl radical (DPPH), nitric oxide and hydrogen peroxide scavenging activities, Fe2+ chelating ability, reducing power and hemoglo...

Ferulago angulata Boiss. known in Iran as Chavir, has some bioactive compounds having antioxidant activity. Because of its antioxidant activities, it sounded Chavir extract can be a good candidate for finding chemopreventive agents having inductive apoptosis properties on cancer cells. In this study, the cytotoxic effects and proapoptotic activities of Chavir's leaf and flower extracts were inv...
