Our study suggests that the global CO fertilization effect (CFE) on vegetation photosynthesis has declined during the past four decades. The Comments suggest that the temporal inconsistency in AVHRR data and the attribution method undermine the results’ robustness. Here, we provide additional evidence that these arguments did not affect our finding and that the global decline in CFE is robust.

Acute ischemic stroke (AIS) remains a leading cause of mortality and long-term disability globally, with survivors at high risk of recurrent stroke, cardiovascular events, and post-stroke dementia. Statins, while widely used for their lipid-lowering effects, also possess pleiotropic properties, including anti-inflammatory, endothelial-stabilizing, and neuroprotective actions, which may offer added benefit in AIS management. This article synthesizes emerging evidence on statins' dual mechanisms of action and evaluates their role in reducing recurrence, improving survival, and mitigating cognitive decline.

Background Elevated brain iron is a potential marker for neurodegeneration, but its role in predicting onset of mild cognitive impairment (MCI) and prospective cognitive trajectories remains unclear. Purpose To investigate how brain iron and amyloid-β (Aβ) levels, measured using quantitative susceptibility mapping (QSM) MRI and PET, help predict MCI onset and cognitive decline. Materials and Methods In this prospective study conducted between January 2015 and November 2022, cognitively unimpaired older adults underwent baseline QSM MRI.

Hepatitis B virus (HBV) infection is a global health challenge, with the World Health Organization (WHO) targeting its elimination by 2030. Jordan lacks sufficient data on HBV epidemiology, including prevalence, incidence and clearance. This study addresses these gaps through a retrospective analysis of HBV testing data from 40,268 individuals collected at Biolab Diagnostic Laboratories (2010-2024).

Intervertebral disc degeneration (IDD) is a major cause of low back pain (LBP), significantly affecting on global disability and healthcare costs. Traditional treatments primarily focus on symptom management rather than addressing the underlying causes, such as the decline in nucleus pulposus (NP) cells and reduced extracellular matrix (ECM) synthesis. Cell therapy shows promise by replenishing NP cells, activating resident cells, and enhancing ECM deposition.

The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging. Although this current tools for studying aging outside of the human body-such as animal models and cells in a dish-have improved this fundamental understanding of the markers and key mechanisms underlying this process, several limitations remain. Animal models are poor biological representations of humans and have a weak track record of translating pre-clinical results into successful clinical applications.
