We used flow cytometry to analyze the expression of adhesion molecules and the oxidative burst of whole-blood polymorphonuclear neutrophils (PMN) from 26 patients with periodontitis. Three different clinical entities were studied: adult periodontitis (AP), localized juvenile periodontitis (LJP), and rapidly progressive periodontitis (RPP). Unstimulated PMN from the patients showed reduced Lewis...

objective: to evaluate the effect of chemical stimuli on germination and seedling growth of caper (capparis spinosa) under drought stress. methods: factorial experiment in a completely randomized design with four replicates per treatment were performed. first factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/l), gibberellic acid levels (500, 250 and 125 ppm), a...

Impaired polymorphonuclear neutrophil (PMN) function may contribute to the onset of certain life-threatening bacterial and fungal infections in human immunodeficiency virus (HIV)-infected patients. Published data on PMN functional activity in HIV infection are controversial, possibly because most studies have involved PMNs isolated from their blood environment by means of various procedures tha...

Research interest into the exposure of plants to magnetic fields (MF), including electromagnetic (EMF), has increased recently but results often vary depending on factors such as plant species and treatment dose. In this study, we exposed young (one year) old (four years) field bean (Vicia faba L. (partim)) seeds EMF (50 Hz, 7 mT) observed seed germination seedling growth under different condit...

there are several methods to increase crops yield, including use of high quality seeds. seed priming is a simple and low-cost method to increase seed quality, if be done right, will lead to increasing plant performance and yield. seed priming treatment applied before planting to enhance germination parameters, seedling establishment and etc. primed seeds get some physiological and biochemical c...

As a resistance elicitor, riboflavin (vitamin B2) protects plants against a wide range of pathogens. At molecular biological levels, it is important to elucidate the signaling pathways underlying the disease resistance induced by riboflavin. Here, riboflavin was tested to induce resistance against virulent Pseudomonas syringae pv. Tomato DC3000 (Pst DC3000) in Arabidopsis. Results showed that r...
