Predicting transcriptional responses to heat and drought stress from genomic features using a machine learning approach in rice.

Plants have evolved various mechanisms to adapt to adverse environmental stresses, such as the modulation of gene expression. Expression of stress-responsive genes is controlled by specific regulators, including transcription factors (TFs), that bind to sequence-specific binding sites, representing key components of cis-regulatory elements and regulatory networks. Our understanding of the underlying regulatory code remains, however, incomplete.

A retrospective long-term pulpal, periodontal, and esthetic, follow-up of palatally impacted canines treated with an open or closed surgical exposure technique using the Maxillary Canine Aesthetic Index.

Introduction: The primary objective of this study was to compare the aesthetic outcome of palatally impacted canines treated with an open or closed surgical exposure technique using the Maxillary Canine Aesthetic Index (MCAI) at least 1 year after debonding. Secondary objectives were set on the periodontal outcome, tooth color, pulpal status, and self-reported contentment.

Methods: The sample of this retrospective study consisted of 53 patients with an average age of 20 years and 7 months at the time of the investigation.

Facial development, continuous tooth eruption, and mesial drift as compromising factors for implant placement.

The replacement of teeth lost by children because of trauma can be an important indication for early implant therapy. Osseointegrated dental implants, like ankylosed teeth, alter position as growth-related changes occur within the jawbones (displacement, remodeling, mesial drift). Facial growth of the child and even of the adolescent, as well as the continuous eruption of the adjacent anterior teeth, create significant risk of a less favorable esthetic and/or functional outcome.

Pathways in multidisciplinary oral health care as a tool to improve clinical performance.

Purpose: To investigate the optimization of multidisciplinary and interdisciplinary oral health care through the introduction of pathways.

Materials And Methods: A prospective randomized clinical trial was carried out in a tertiary referral academic institution. Ninety-one patients admitted for multidisciplinary oral health care from January 1, 2001, to March 31, 2003, were randomized to the test group (n = 50) or to the control group (n = 41).
