in this work, the solubility of nicotine extracted from tobacco leaves, found in the north of iran, in supercritical carbon dioxide has been measured. also the effects of pressure, temperature, extraction dynamic time, and the organic co-solvent on the amount of nicotine extracted from tobacco leaves have been investigated. it should be stressed that in order to reduce significantly the number ...

Background The study aimes to determine the effect of administering anti-T. gondii membrane IgY against liver damage (Necrotic index) and the effectiveness of the antibody's delivery time. Materials and Methods This research was a laboratory experiment with five treatments and five replicantions. Each treatment used female mice (Mus musculus) as animal models. The treatment groups consisted o...

The research was undertaken to determine if the plug tray cell size had an impact on plant characteristics and yield of corn salad (Valerianella olitoria L.). Seeds of four cultivars (‘Ljubljanski’, ‘Holandski’, ‘Flavor’ and ‘Masse’) were sown in styrofoam plug trays with 40 cells (60 ml cell), 84 cells (35 ml cell) and 160 cells (20 ml cell). Plants growth generally increased with cell size, t...

One of the challenges facing farmers today is to ensure adequate integration of natural resources into animal feeds. The aim of the present study is to evaluate the effects of Khaya senegalensis (KS) leaves on the performance of growing male rabbits, carcass traits and biochemical as well as hematological parameters. Thirty New Zealand White male growing rabbits were randomly divided into 3 gro...

OBJECTIVES To assess the outcome of core decompression in the treatment of osteonecrosis of the femoral head related to the volume of necrotic bone measured according to a previously reported method. METHODS Twenty hips corresponding to strictly Ficat stage II underwent magnetic resonance imaging and the volume of necrotic bone was expressed as a percentage of the volume of the entire head me...

BACKGROUND AND OBJECTIVE Some studies have shown that laser phototherapy is able to increase skin flap viability by decreasing the necrotic area and increasing neoangiogenesis. However, the mechanism by which laser acts on cells is not fully understood. The present study investigated the effects of two different laser wavelengths at 30 and 40 J/cm(2) on the viability of skin flap in rats. MAT...

A comparative study was done on the dry oils isolated from the leaves and stem portions of Corchrus olitorius (Linn.) growing in Saudi Arabia. Oils were obtained by column chromatography and analysed by Gas Chromatography (GC), Gas Chromatography/Mass Spectrometry (GC/MS) and 13C NMR spectroscopy. The investigation led to the identification of 22 components in leaves oil while as 23 components ...

in order to investigate the in vitro micropropagation hibiscus rosa-sinensis three tests in a completely randomized design with 10 replications were performed in tissue culture laboratory shahid chamran university in 2014.the first experiment showed the perfect media.second tests best consentration bap for multiplication and third tests showed the best type and concentration rooting hormone. co...

Limited information is known on the basic biology of the recently described Phytophthora kernoviae that produces homothallic oospores. In this study, different P. kernoviae isolates were used to investigate oospore maturity, germination, and infection. All isolates produced oospores in V8 broth at 20°C in the dark by 6d. Oospores also formed at 10 and 15°C, but did not form at 25 and 28°C. Cont...
