Melatonin-governed growth and metabolome divergence: Circadian and stress responses in key plant species.

Melatonin, a versatile biomolecule, profoundly influences plant growth and resilience through its intricate regulation of metabolic pathways, circadian rhythms, and cellular processes. The current study elucidates melatonin's concentration-dependent biphasic effects on growth dynamics in Arabidopsis thaliana and Brassica nigra. While 50 μM melatonin optimized biomass accumulation and root elongation, higher concentrations (100 μM) elicited stress responses, underscoring its dual role as a growth promoter and stress modulator.

Diagnostic Utility of Bedside "Point of Care Lung Ultrasound" in Predicting the Need For NICU Admission in Late Preterm and Term Newborns Having Respiratory Distress Soon After Birth in the Transition Period: A Prospective Observational Study.

Background: Point of care lung ultrasound (POC-LUS) is a rapid and simple method to evaluate infants with respiratory distress after birth.

Objectives: The primary objective was to determine whether the POC-LUS score is a good predictor of NICU admission in late preterm and term infants born with respiratory distress when performed within the first 2 h of life. The secondary objective was to find a correlation between the LUS score and the clinical respiratory distress severity score.

What happens when you turn weed management off? A long-term appraisal of the effectiveness of Pteridium aquilinum (L.) kuhn control treatments and the role of sheep grazing.

Long-term strategies are needed for the ecological restoration of land invaded by perennial weed species comprising of two parts: (1) control of the invasive species and (2) restoration of native vegetation meeting agricultural/conservation objectives. We investigated this within a statistically-rigorous, 28-year experiment at a site where Pteridium aquilinum had invaded an acid-grass/heathland. Where P.

Fracture Strength of Tooth Roots Following Canal Preparation by Three Rotary File Systems: An In Vitro Study.

Background: Since the beginning of modern endodontics, there have been many concepts, strategies, and techniques for root canal preparation. A mind-boggling variety of files have developed for negotiating and shaping them throughout the years. Today's most secure, most effective, and simplest file system combines the most reliable design elements of the past with the latest technological advances to create the most effective file system.
