The Black Sea basin has a strategic geographic location bridging Asia and Europe and depends on traditional livestock practices for their local economies. Anthrax, a zoonotic bacterial disease caused by Bacillus anthracis, poses a significant global threat impacting public health, food security, pastoralist communities, and national economies. The disease is endemic or sporadic in the Black Sea basin, however, the study of its distribution has seldom been addressed, despite its burden and the presence of historical B.

- - The NADIM trial was a phase 2 study in Spain that evaluated the effects of perioperative immunotherapy on long-term outcomes in patients with stage IIIA non-small-cell lung cancer (NSCLC), showing positive short-term results previously. - A total of 46 treatment-naive patients participated, receiving a combination of chemotherapy and nivolumab before surgery, followed by more nivolumab as adjuvant therapy, with the study measuring 5-year progression-free and overall survival rates. - Findings showed that after 5 years, 65% of patients were progression-free and 69% had overall survival, with disease progression seen in 24% of patients and 30% dying by the end of the follow-up period.
Shade-induced ROS/NO reinforce COP1-mediated diffuse cell growth.

Article Synopsis
- Canopy shade activates PHYTOCHROME INTERACTING FACTORS (PIFs), which boosts auxin synthesis in cotyledons, promoting hypocotyl growth for better light access.
- The study explores how shade influences cellular redox status and finds that high auxin levels under shade increase reactive oxygen species and nitric oxide in the hypocotyl.
- COP1, a positive growth regulator, is affected by redox regulation; when this mechanism is disrupted, it leads to poor hypocotyl growth coordination and reduced competitive ability against neighboring plants.
Abscisic acid (ABA) and gibberellic acid (GA) are regulators of fruit color and sugar levels, and the application of these hormones is a common practice in commercial vineyards dedicated to the production of table grapes. However, the effects of exogenous ABA and GA on wine cultivars remain unclear. We investigated the impact of ABA and GA application on Malbec grapevine berries across three developmental stages.

This interplay creates a complex, fluctuating light environment within plant canopies. Shade-intolerant species rely on light cues from competitors to trigger shade avoidance responses, ensuring access to light for photosynthesis.
