Intervention based on shared story reading: effect on low and high challenge reading and writing tasks.

Purpose: to investigate the effectiveness of an intervention proposal based on shared story reading for reading comprehension, written narrative and word reading/writing.

Methods: 44 children were divided into two groups according to their performance in a reading comprehension test - The first group, G1, consisted of children with reading comprehension difficulty, and the second, G2, consisted of children who did not have difficulties. All children were evaluated regarding reading/writing isolated words, reading comprehension of sentences, and written narrative.

Integration of genetic, genomic and transcriptomic information identifies putative regulators of adventitious root formation in Populus.

Background: Adventitious roots (AR) develop from tissues other than the primary root, in a process physiologically regulated by phytohormones. Adventitious roots provide structural support and contribute to water and nutrient absorption, and are critical for commercial vegetative propagation of several crops. Here we quantified the number of AR, root architectural traits and root biomass in cuttings from a pseudo-backcross population of Populus deltoides and Populus trichocarpa.

Genetical genomics of Populus leaf shape variation.

Background: Leaf morphology varies extensively among plant species and is under strong genetic control. Mutagenic screens in model systems have identified genes and established molecular mechanisms regulating leaf initiation, development, and shape. However, it is not known whether this diversity across plant species is related to naturally occurring variation at these genes.

STUDY ON THE APPLICABILITY OF THE MODIFIED TOKUHASHI SCORE IN PATIENTS WITH SURGICALLY TREATED VERTEBRAL METASTASIS.

Unlabelled: To present the results obtained from surgical treatment of patients with vertebral metastases, comparing them with the modified Tokuhashi score in order to validate the applicability of this score for prognostic predictions and for choosing surgical treatments.

Methods: This was a retrospective study on 157 patients treated surgically for spinal metastasis in Erastus Gaertner Hospital in Curitiba. The Tokuhashi score was applied retrospectively to all the patients.

Diversification in the genetic architecture of gene expression and transcriptional networks in organ differentiation of Populus.

A fundamental goal of systems biology is to identify genetic elements that contribute to complex phenotypes and to understand how they interact in networks predictive of system response to genetic variation. Few studies in plants have developed such networks, and none have examined their conservation among functionally specialized organs. Here we used genetical genomics in an interspecific hybrid population of the model hardwood plant Populus to uncover transcriptional networks in xylem, leaves, and roots.
