During a screen of bacterial nutrients as inhibitors of Escherichia coli O157:H7 biofilm, the Prüß research team made an intriguing observation: among 95 carbon and 95 nitrogen sources tested, β-phenylethylamine (PEA) performed best at reducing bacterial cell counts and biofilm amounts, when supplemented to liquid beef broth medium. This review article summarizes what is known about PEA. After ...

The aim of the present study was to evaluate the response of grain yield, phosphorus (P) use efficiency (PUE, g yield g–1 P available) and related root traits of wheat and pea to different P availabilities in a high yielding environment (e.g.: yield higher than 10 Mg ha-1 for wheat). Two experiments were conducted in southern Chile. Treatments consisted of the combination of (i) two crops (spri...

Autophagy, an ancient homeostasis mechanism for macromolecule degradation, performs an important role in host defense by facilitating pathogen elimination. To counteract this host defense strategy, bacterial pathogens have evolved a variety of mechanisms to avoid or otherwise dysregulate autophagy by phagocytic cells so as to enhance their survival during infection. Neisseria gonorrhoeae is a s...

Polysaccharide biopolymers have been shown to be alternatives established dust suppressants. This study investigates the potential of 14 polysaccharides and proteins from diverse botanical (corn, pea, wheat, cellulose, potato, fava bean) animal (pig, chicken, cow) sources as suppressants on two mine soils (medium-grained sand fine-grained silica sand). Results laboratory tests demonstrate that ...

background and objectivesintercropping or simultaneous growing of two or more crops on the same piece of land has the potential of enhanced ecosystem productivity. in a cereal-legume intercropping system, an increase in cereal and a decrease in legume intercrop yield is reported. several indices such as land equivalent ratio (ler), relative crowding coefficient (k), competitive ratio (cr), aggr...

This paper shows how it is possible to use agents and ontologies to deal with dynamic coordination of business processes in Cross-Organizational Workflow (COW). The aim of COW is to support the cooperation between distributed and heterogeneous business processes running in different autonomous organizations to reach a common goal, corresponding to a value-added service. In this paper, we consid...

The growth and development of Helicoverpa armigera was observed in the laboratory by feeding them on different foods viz; leaf, flower and fruit of lady finger, cotton, pigeon pea and chick pea. Based on the food ingested, food digested and food excreted as well as on weight and size of the larvae and the duration of larval period, the fruit of chick pea was found to be the most suitable food f...

Phacoemulsification and aspiration (PEA) has become the most popular cataract surgery, due to the establishment of safe surgical techniques and development of associated instruments. However, corneal endothelial damage still represents a serious complication, as excessive damage can lead to irreversible bullous keratopathy. In addition to causes such as mechanical or heat injuries, free radical...

The goal of this study was to examine the effect of palmitoylethanolamide (PEA) on the capacitation process and hyperactivated motility (HA) in idiopathic infertile men. Our data show the effect of PEA on the kinematic parameters of sperm cells from idiopathic infertile men during the capacitation of spermatozoa in vitro, both in the presence and absence of 2.5 nM PEA, a molecule physiologicall...

Ileal digesta were collected via a post-valve-T-caecum cannula from piglets ( lo-15 kg) fed diets based on raw pea or on pea protein isolate (Finale or Frijaune variety). From the determined amino acids (AA) content of feed and digesta, AA apparent digestibility coefficients and proportions of proteins (endogenous, bacterial, dietary) theoretically present in digesta were calculated. Four essen...
