Smart polymers and smartphones for Betalain measurement in cooked beetroots.

Betalains in beetroots offer notable colouring properties and health benefits, including antioxidant, anti-inflammatory, hepatoprotective, and antitumorous activities. However, they degrade due to processing and storage conditions like temperature, pH, oxygen, and light-exposure. Traditional betalain determination methods are resource-intensive solid-liquid extractions.

Functional inferior canalicular reconstruction using a monocanalicular probe after tumor resection of the medial third of the lower eyelid.

Purpose: To describe a surgical technique for functionally reconstructing a lacrimal drainage duct and to assess its long-term functionality.

Methods: This observational review includes six cases involving reconstruction of the inferior canaliculus after surgical resection of lower eyelid carcinoma. Following lesion excision with safety margins, the epithelium of the distal portion of the inferior canaliculus is located and intubated with a monocanalicular probe.

Contrasting plant transcriptome responses between a pierce-sucking and a chewing herbivore go beyond the infestation site.

Background: Plants have acquired a repertoire of mechanisms to combat biotic stressors, which may vary depending on the feeding strategies of herbivores and the plant species. Hormonal regulation crucially modulates this malleable defense response. Jasmonic acid (JA) and salicylic acid (SA) stand out as pivotal regulators of defense, while other hormones like abscisic acid (ABA), ethylene (ET), gibberellic acid (GA) or auxin also play a role in modulating plant-pest interactions.
