The sternohyoid muscle flap for new dynamic facial reanimation technique: Anatomical study and clinical results.

Background: Long-term facial nerve palsy has a highly negative impact on patients' quality of life. In 2016, Alam reported one case of facial reanimation with the sternohyoid muscle after publishing a preclinical study in 2013. Despite the potentially ideal characteristics of this muscle for reanimation of facial palsy, this technique is still not widely used.

Effect of Passive Ultrasonic Activation on Organic Tissue Dissolution from Simulated Grooves in Root Canals Using Sodium Hypochlorite with or without Surfactants and EDTA.

Introduction: The aim of this study was to evaluate the porcine palatal mucosa dissolution from artificial grooves using a final rinse with sodium hypochlorite (NaOCl) with or without a surfactant or ultrasonic activation (PUI).

Methods: The root canals of 130 human maxillary central incisors were chemomechanically prepared and the teeth split. A standardized longitudinal intracanal groove was created in 1 of the root halves.

Genetic transformation of grapevine cells using the minimal cassette technology: the need of 3'-end protection.

The use of minimal cassettes (linear DNA comprising promoter+open reading frame+terminator) for genetic transformation offers a means of transforming plant cells by biolistics without introducing unwanted sequences. However, a species-specific approach of the factors involved in successful transformation with this technology is advisable. Protection of the minimal cassette upstream promoter and downstream terminator may be necessary due to the nuclease activity of target plant material.

Invasive cervical resorption Class III in a maxillary central incisor: diagnosis and follow-up by means of cone-beam computed tomography.

Introduction: Invasive cervical resorption (ICR) is a type of external resorption that begins below the epithelial attachment. The etiology of ICR is mainly caused by trauma or orthodontic treatment. In many cases, cone-beam computed tomography (CBCT) is a very useful tool to achieve proper diagnosis.

Single-rooted maxillary first molar with a single canal: endodontic retreatment.

This case report presents an unusual root canal system in a maxillary first molar tooth: a single canal in a single root. The endodontic access cavity displayed only 1 canal orifice. This case demonstrated that: 1) clinicians must have adequate knowledge about root canal morphology and its variations; 2) the location and morphology of root canals should be identified radiologically before the root canal treatment; and 3) careful examination of radiographs and the internal anatomy of teeth is essential.

How ethylene works in the reproductive organs of higher plants: a signaling update from the third millennium.

Ethylene (ET) is a notable signaling molecule in higher plants. In the year 1993 the ET receptor gene, ETR1, was identified; this ETR1 receptor protein being the first plant hormone receptor to be isolated. It is striking that there are six ET receptors in tomato instead of five in Arabidopsis, the two best-known signaling-model systems.

AtFXG1, an Arabidopsis gene encoding alpha-L-fucosidase active against fucosylated xyloglucan oligosaccharides.
