Potato cultivars Katahdin (susceptible) and Rosa (resistant) were exposed to infective second-stage juveniles (J2) of Globodera rostochiensis for varying periods of time, after which root systems were washed and plants were placed in Hoagland's solution to assess J2 egression and male emergence. After transfer to liquid culture, many J2 egressed from both cultivars, but significantly more egres...

ROSA is an e-learning system, which enables the management of Learning Objects (LOs). However, since ROSA is a centralized system, it does not provide a complete integration of LOs created in local ROSAs of other institutions. This paper presents the evolution of ROSA into a peer-to-peer (P2P) system the ROSA P2P, and describes the integration process of LOs in this environment. It provides the...

Objective: The antiulcer activity of various extracts of Hibiscus rosa sinensis leaves was evaluated in pyloric ligation induced gastric ulcer in albino rats. Method: The leaves extracts were prepared by cold maceration process with petroleum ether, alcohol and water separately. Results: Oral administration of aqueous and alcohol extracts (200 and 400 mg/kg) of Hibiscus rosa sinensis leaves wer...

BACKGROUND Nowadays there is a need to find naturally occurring substances from plants with antimicrobial activity as an alternative to available used antibiotics. MATERIALS AND METHODS Salvadora persica (miswak) and Commiphora gileadensis were collected, dried and extracted with either methanol or warm water and the obtained extracts were assessed for their antibacterial activity against 5 d...

OBJECTIVE To evaluate the antimicrobial properties of several mouthwash concentrations on oral Streptococcus mutans and Escherichia coli. METHODS The study was conducted at Shiraz Medicine School in 2011. Serial dilutions of Chlorohexidin, Oral B and Persica and Irsha (2,4,8,16,64,128) were prepared in Muller-Hinton media. Minimum inhibitory concentration was visually determined and defined a...

The flowers of Prunus persica Batsch have been used for skin disorders in East Asia from ancient times. In this investigation, the ethanol extract from this plant material was prepared and several major constituents were isolated. In addition, the protective effects of the extract were evaluated against solar ultraviolet (UV)-induced skin damage using in vivo animal models of UVB-induced erythe...

The domestication of halophytes has been proposed as a strategy to expand cultivation onto unfavorable land. However, halophytes mainly have been considered for their performance in extremely saline environments, and only a few species have been characterized in terms of their tolerance and physiological responses to moderately high levels of salinity. Salvadora persica is an evergreen perennia...

We studied relationships between diurnal patterns of stem water potential (PsiSTEM) and stem extension growth of the same scion cultivar growing on three rootstocks with differing size-controlling potentials. The peach trees (Prunus persica (L.) Batsch) used in this field experiment consisted of an early-maturing freestone cultivar, 'Flavorcrest,' grafted onto three different rootstocks: Nemagu...

The aim of the present study was to evaluate the anxiolytic effects of hydroalcoholic extract (HE) of Nepeta persica Boiss. (Lamiaceae) on the elevated plus-maze (EPM) model of anxiety. The extract of arial parts of the plant was administered intraperitoneally to male NMRI mice, at various doses, 30 min before behavioural evaluation. The HE extract of N. persica at the dose of 50 mg kg(-1) sign...
