Many food products are claimed to be effective in controlling halitosis. Halitosis is caused mainly by volatile sulfur compounds (VSCs) such as H(2)S and CH(3)SH produced in the oral cavity. Oral microorganisms degrade proteinaceous substrates to cysteine and methionine, which are then converted to VSCs. Most treatments for halitosis focus on controlling the number of microorganisms in the oral...

The elicitor-induced incorporation of phenylpropanoid derivatives into the cell wall and the secretion of soluble coumarin derivatives (phytoalexins) by parsley (Petroselinum crispum L.) suspension cultures can be potentiated by pretreatment of the cultures with 2,6-dichloroisonicotinic acid or derivatives of salicylic acid. To investigate this phenomenon further, the cell walls and an extracel...

OBJECTIVES This study sought to investigate the effects of pretransplant nutrient content, nutritional status, and nutritional habits on the clinical outcome of children undergoing hematopoietic stem cell transplant. MATERIALS AND METHODS Forty-one children were enrolled in this study. Dietary assessment was based on a semiquantitative food frequency questionnaire, consisting of 47 food items...

phytochemical screening, antibacterial and cytotoxic activities of petroselinum crispum leaves grown in oman.petroselinum crispum belongs to the apiaceae family, is a well-known spice and vegetable. the essential oil obtained from the fruit has also strong action on the central nervous system. present study is designed to evaluate the phytochemical screening, antibacterial and cytotoxic activit...

In Europe and the Mediterranean region, ‘Candidatus Liberibacter solanacearum’ (Lso) is associated with emerging diseases of Apiaceae crops, mainly carrot. Emergency measures for import carrot seed were set, requiring to be heat-treated at 50°C or tested as Lso-negative by PCR. The germination response heat treatment was assessed 24 cultivar hybrid lots. Ten parsley, five fennel, two celery lot...

We investigated the effects of three botanicals with nematicidal properties (anise-Pimpinella anisum, parsley-Petroselinum crispum, and rocket-Eruca sativa) on soil nematode community, in terms trophic structure genera composition. compared those fluopyram (synthetic nematicide) Nemagold (bionematicide). assessed role time, by sampling 15 45 days after treatments analyzing microbial phospholipi...

The presence of various enzyme forms with terminal action pattern on pectate was evaluated in a protein mixture obtained from parsley roots. Enzymes found in the soluble fraction of roots (juice) were purified to homogeneity according to SDS-PAGE, partially separated by preparative isoelectric focusing and characterized. Three forms with pH optima 3.6, 4.2 and 4.6 clearly preferred substrates w...

Parsley (Petroselium crispum L.) is commonly used for its flavor, desired nutritional contents, and other health benefits. However, since the profile of a recently introduced curly-leafed parsley cultivar in Egypt has not been studied, an experiment was conducted to compare three harvest dates terms weight, essential oil (EO) content yield, concentrations major components whole herb, leaf, stem...

Objective(s): In recent years, green synthesis of nanoparticles is under exploration due to wide medicine and biological applications and research interest in nanotechnology. Green synthesis of zinc oxide nanoparticles (ZnO NPs) is becoming increasingly importance as eco-friendly. The objectives of this study were the production of zinc oxide nanoparticles using pars...
