Nitric oxide, a ubiquitous molecule found throughout the natural world, is a key molecule implicated in many central and benefic molecular pathways and has a well-established role in the function of the central nervous system, as numerous studies have previously shown. Dysregulation of its metabolism, mainly the upregulation of nitric oxide production, has been proposed as a trigger and/or aggravator for many neurological affections. Increasing evidence supports the implication of this molecule in prevalent neurodegenerative diseases, such as Parkinson’s disease, Alzheimer’s disease, or amyotrophic lateral sclerosis. The mechanisms proposed for its neurotoxicity mainly center around the increased quantities of nitric oxide that are produced in the brain, their cause, and, most importantly, the pathological metabolic cascades created. These cascades lead to the formation of neuronal toxic substances that impair the neurons’ function and structure on multiple levels. The purpose of this review is to present the main causes of increased pathological production, as well as the most important pathophysiological mechanisms triggered by nitric oxide, mechanisms that could help explain a part of the complex picture of neurodegenerative diseases and help develop targeted therapies.

Anthyllis vulneraria is a traditional medicinal plant with confirmed anti-inflammatory properties, attributed to its high polyphenolic content. This study aimed to evaluate the wound-healing potential of A. vulneraria leaf extract in a rat burn model. Four groups of eight Wistar rats each received the following daily topical applications for 14 days: vehicle cream (negative control); silver sulfadiazine (positive control); or plant-based creams containing either 1 mg/cm² or 2 mg/cm² of polyphenols (experimental groups 1 and 2, respectively). On days 7 and 14, four animals per group were euthanized for histological and oxidative stress evaluations. LC-MS/MS analysis of the leaf extract identified hyperoside, ferulic acid, and p-coumaric acid as major constituents. Experimental group 1 showed significantly enhanced wound closure on days 5 and 7, while group 2 exhibited a significant effect on day 5. All oxidative stress markers, except catalase activity, differed significantly among the groups, with the most favorable results observed in group 2. IL-8 levels decreased after the extract treatment, while no significant microscopic changes were observed. These results indicate that A. vulneraria leaf extract may serve as a valuable adjuvant in burn wound healing.

Anaplastic thyroid carcinoma (ATC) represents the most aggressive thyroid malignancy, characterized by rapid progression, therapeutic resistance, and poor prognosis. Conventional treatments remain largely ineffective, highlighting the need for novel therapies. Metabolic reprogramming, particularly the Warburg effect (WE), has emerged as a promising area of investigation. This review synthesizes current evidence on the role of WE in ATC and PDTC, integrating data from molecular profiling, preclinical studies, and emerging therapeutic strategies. Oncogenic alterations frequently observed in ATC, including mutations in BRAF, RAS, TP53, and activation of PI3K/AKT/mTOR and HIF-1α signaling, converge to promote glycolytic reprogramming. This metabolic shift supports tumor proliferation, immune evasion, and metastasis through increased glucose uptake, lactate production, and microenvironmental remodeling. Key metabolic nodes, including glucose transporters, hexokinase, and monocarboxylate transporters, are regarded as promising targets. Preclinical studies suggest that pharmacological inhibition of these pathways reduces tumor growth, enhances radiosensitivity, and improves response to targeted therapies. Future efforts should focus on combination therapies, biomarker-driven patient stratification, and the development of targeted delivery systems to overcome toxicity and resistance. A deeper understanding of tumor metabolic heterogeneity will be essential for translating these approaches into clinical practice.
