Extreme environments significantly impact the metabolic profiles of plants, leading to variations in chemical composition and bioactivity. This study investigates the effects of altitude, plant part age, and light exposure on the chemical composition and antimicrobial properties of Moringa peregrina. Based on our results, mineral contents were plant location dependent; while dry matter, ash, total digestible nutrients (TDN), fibre, protein, and tannins, were greater in the samples from the mountain. Vitamin E was more concentrated in the wadi. Vitamin A, selenium, phenols, and heavy metals were undetectable in both environments. Antimicrobial assays revealed stronger activity in mountain samples than the other locations. Age-dependent analyses showed that nitrogen, protein, ash, and electrolyte leakage were higher in young plant parts, whereas chlorophyll a and b levels were elevated in mature leaves and younger branches, particularly in lower elevations. Interestingly, young leaves from mountain regions had higher chlorophyll concentrations compared to mature leaves, contrasting with trends at other elevations. Photosynthetic photon flux density (PPFD) measurements were also highest in the mountain region. These findings suggest that M. peregrina employs diverse metabolic adaptations for survival in challenging environments, potentially offering socioeconomic value to indigenous communities through its bioactive properties.

MXenes, a novel class of two-dimensional materials, have recently emerged as promising candidates for biomedical applications due to their specific structural features and exceptional physicochemical and biological properties. These materials, characterized by unique structural features and superior conductivity, have applications in tissue engineering, cancer detection and therapy, sensing, imaging, drug delivery, wound treatment, antimicrobial therapy, and medical implantation. Additionally, MXene-based composites, incorporating polymers, metals, carbon nanomaterials, and metal oxides, offer enhanced electroactive and mechanical properties, making them highly suitable for engineering electroactive organs such as the heart, skeletal muscle, and nerves.

Introduction: Older patients with acute myeloid leukemia (AML) respond poorly to standard induction therapy. DNA methyltransferases (DNMTs) and histone-deacetylases (HDACs) are key regulators of gene expression in cells and have been investigated as important therapeutic targets. However, their effects remains unclear as induction therapy for AML.

Bone infection remains a challenging condition to fully eradicate due to its intricate nature. Traditional treatment strategies, involving long-term and high-dose systemic antibiotic administration, often encounter difficulties in achieving therapeutic drug concentrations locally and may lead to antibiotic resistance. Bone cement, serving as a local drug delivery matrix, has emerged as an effective anti-infective approach validated in clinical settings.

The lack of bone grafts represents a major issue in the orthopedic field, reconstructive surgery, and dentistry. There are several bone conditions that often demand the use of grafts, such as fractures, infections, and bone cancer. The number of bone cancer cases increased in the past few decades and along with it, the need for bone grafting materials.

Zinc has attracted significant attention as a versatile material with potential applications in various fields, particularly in biomedical engineering. Despite its desirable characteristics, such as biodegradability and biocompatibility, the inherently low mechanical strength of zinc has been a major limitation for its broader use in clinical applications. To address this issue and enhance its mechanical performance without compromising its biocompatibility, a novel composite material was developed by mixing zinc oxide (ZnO) with zinc (Zn).
