Usefulness of admission hematologic parameters as diagnostic tools in acute pulmonary embolism.

The purpose of this study was to determine the role of red cell distribution width (RDW), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) in the diagnostic phase of acute pulmonary embolism (PE). We screened 248 consecutive patients who were admitted to the emergency service with PE foremost in the differential diagnosis. Based on spiral computed chest tomography, the patients were divided into two groups.

In planta expression or delivery of potato aphid Macrosiphum euphorbiae effectors Me10 and Me23 enhances aphid fecundity.

The interactions between aphids and their host plants seem to be analogous to those of plant-microbial pathogens. Unlike microbial pathogen effectors, little is known about aphid effectors and their ability to interfere with host immunity. To date, only three functional aphid effectors have been reported.

NT-Pro-BNP levels and their response to exercise in patients with slow coronary flow.

Background: Natriuretic peptides are released by the heart in response to wall stress.

Objective: The NT-Pro-BNP concentrations in slow coronary flow (SCF) patients were assessed before and after the exercise test and compared with the values of healthy controls.

Methods: The study population was 34 patients with SCF [22 males (64.

The role of light on foliage colour development in coleus (Solenostemon scutellarioides (L.) Codd).

Many coleus (Solenostemon scutellarioides (L). Codd) varieties change pigmentation when exposed to high light intensity: they increase anthocyanin amount and decrease chlorophyll content. The physiological and molecular mechanisms involved in this phenomenon have been investigated in two independent experiments using two related coleus varieties 'Royal Glissade' (RG) and 'UF06-1-06' (UF).

Flavour compounds in tomato fruits: identification of loci and potential pathways affecting volatile composition.

The unique flavour of a tomato fruit is the sum of a complex interaction among sugars, acids, and a large set of volatile compounds. While it is generally acknowledged that the flavour of commercially produced tomatoes is inferior, the biochemical and genetic complexity of the trait has made breeding for improved flavour extremely difficult. The volatiles, in particular, present a major challenge for flavour improvement, being generated from a diverse set of lipid, amino acid, and carotenoid precursors.
