Leaf photosynthesis models are used extensively in photosynthesis research and are embedded in many larger scale models. Typical photosynthesis models simplify light intensity as the integrated intensity over the 400-700 nm waveband (photosynthetic active radiation, PAR). However, far-red light (700-750 nm, FR) also drives photosynthesis when supplied in addition to light within the PAR spectrum.

This study aims to determine if there is an association between intraoperative regional cerebral oxygenation (ScO) monitoring using near-infrared spectroscopy (NIRS) and the occurrence of early perioperative stroke within three days after cardiothoracic surgery.
Methods: We performed a single-center retrospective observational cohort study including all consecutive cardiothoracic surgery patients with routinely perioperative ScO monitoring admitted postoperatively to the Intensive Care Unit (ICU) between 2008 and 2017.
Study Design: Retrospectively matched case-control study.
Objective: To compare intraoperative and postoperative outcomes between separation surgery and corpectomy with anterior reconstruction for patients with metastatic epidural spinal cord compression (MESCC).
Summary Of Background Data: The primary goal of surgery for MESCC is to preserve and improve neurological function.
Study Design: Retrospective propensity-score matched, case control study at 2 academic tertiary care centers.
Objective: To assess the effect of PE on (1) intraoperative blood loss, defined as conventional estimates of blood loss (EBL) and hemoglobin mass loss, and (2) secondary outcomes in patients with spinal metastases from hypervascular histologies.
Background Context: Preoperative embolization (PE) intends to reduce blood loss during surgery for spinal metastases of hypervascular tumors such as renal cell carcinoma.
Article Synopsis
- This study looks at how three plant hormones—gibberellins (GA), brassinosteroids (BR), and Indole-3-Acetic Acid (IAA)—work together to help plants grow taller when there's less light.
- Researchers focused on tomato plants in low Red:Far-red light conditions to see how these hormones affected stem elongation.
- They found that while GA and BR are really important for making the plants grow tall, IAA is not as helpful on its own, but works well with GA, showing how these hormones balance each other out.
