Hydrogen Sulfide (H2S) is an essential gaseous signaling molecule involved in various physiological processes, including vasodilation, neurotransmission, and anti-inflammatory responses. Accurate detection and quantification of H2S in biological systems are crucial for elucidating its physiological and pathological roles. Fluorescent probes have emerged as indispensable tools for H2S detection, offering high sensitivity, specificity, and the ability for real-time and non-invasive monitoring. This review discusses recent advances in the design and development of fluorescent probes for H2S detection, focusing on their mechanisms, properties, and applications. We explore the different strategies employed in probe design, including reduction-based mechanisms, nucleophilic addition reactions, and cleavage of sulfide bonds. Innovations such as ratiometric probes, two-photon fluorescent probes, and multi-functional probes have significantly enhanced the capabilities of H2S detection. These advancements have facilitated cellular and subcellular imaging, real-time monitoring in live organisms, and the investigation of H2S-related pathologies. Despite these progresses, challenges remain, including improving probe selectivity, stability, and biocompatibility, as well as developing methods for accurate quantification in complex biological matrices. Future research directions include designing probes with higher selectivity and sensitivity, integrating advanced computational modeling, and combining fluorescent probes with mass spectrometry for precise quantification. The continued development of sophisticated fluorescent probes will expand our understanding of H2S biology, offering new insights into its physiological and pathological roles and paving the way for novel therapeutic strategies.

Nitric oxide (NO) plays a crucial role in various physiological processes, making its detection and controlled release significant for both therapeutic and environmental contexts. Electrochemical sensors are widely used for NO detection due to their high sensitivity and real-time monitoring capabilities. However, challenges such as interference from other gasotransmitters, sensor degradation, and calibration difficulties—especially in complex biological matrices—hinder accurate NO measurement. This review discusses recent advancements in electrochemical NO detection, with a focus on the impact of complex biological matrices, calibration strategies, and sensor designs. The release of NO from nanoparticles, such as S-nitrosoglutathione (GSNO)-encapsulating chitosan nanoparticles, is used as a case study for improving NO detection accuracy. Future innovations in sensor technology and nanoparticle design are expected to expand the applicability of NO detection in personalized medicine and environmental monitoring.

Plant growth and development are negatively impacted by root-knot nematodes (RKNs), which in turn affects plant production. Chemical nematicides are one of the effective strategies for managing RKNs. But, high concentration of these chemicals is toxic to plants, environment and humans. Therefore, an in-vivo study was conducted to unravel the synergistic interplay sodium nitroprusside (SNP: nitric oxide donor) and, Serratia marcescens in M. incognita-stressed tomato plants. Results revealed that treatment with SNP and bacterial culture cells reduced gall formation and improved morphology. It also reduced nematode-induced oxidative stress in M. incognita-infested tomato plants as compared to untreated plants. Increased photosynthetic parameters including photosynthetic pigments and gas-exchange parameters was also observed in treated plants. Additionally, treated plants exhibited increased antioxidant defense system in terms of upregulated activities of enzymatic antioxidants (Ascorbate peroxidase, guaiacol peroxidase, polyphenol oxidase, catalase, glutathione-S-transferase and superoxide dismutase). Content of non-enzymatic antioxidants (Glutathione, ascorbic acid and tocopherol) was also enhanced in treated plants as compared to untreated nematode-infected plants. Further, treatment with SNP and S. marcescens increased secondary metabolites (total phenol, flavonoid and anthocyanin) and proline content. Reduction in nematode-induced nuclear and membrane damage was also observed in SNP and bacterial culture cells treated tomato plants. The integrative application of SNP and S. marcescens exhibited synergism and overpowered their individual application in reducing the negative effects of nematode stress. The findings of the current investigation suggest the integrative use of SNP and bacteria is more beneficial in alleviating nematode stress in plants.

Context
Nitric oxide is a vasodilator molecule that acts on blood pressure (BP) control, and its production can occur through the reduction of nitrates by oral or intestinal nitrate-reducing bacteria. However, the relationship between nitrate-reducing bacteria and arterial hypertension (HTN) remains under debate.
Objective
Systematically review if there is an association between the abundance of oral and intestinal nitrate-reducing bacteria and the occurrence of HTN in humans.
Databases and eligibility criteria
MEDLINE, Scopus, Cochrane Library, EMBASE, LILACS, Web of Science, Livivo, ProQuest Dissertations, and Google Scholar were searched for eligible articles until February 10th, 2024. Studies were included if they: (1) were observational studies or clinical trials; (2) included adults (≥18 years old) with HTN (systolic BP ≥ 130 mmHg and/or diastolic BP > 80 mmHg and/or use of BP lowering medication); (3) compared (or not) to no-HTN adults; and (4) used next-generation sequencing microbiome analysis to identify bacterial taxa in the oral and/or gut nitrate-reducing bacteria.
Results
The search identified 9365 articles, and 28 were included in the study after applying the inclusion and exclusion criteria; 23 articles assessed the gut microbiota, 4 assessed the oral microbiota, and 1 assessed both. Depletion of nitrate-reducing bacteria was not consistently shown in the studies. The included studies reported reduction, increase, and no change in the nitrate-reducing bacteria genera or species in oral or gut microbiota.
Conclusion
We found no association between the abundance of oral and gut nitrate-reducing bacteria and the occurrence of HTN in humans.

Sulfur-containing amino acids are involved in the regulation of vascular activity and blood pressure. Clinically, a positive correlation was found between serum homocysteine levels and blood pressure. On the other hand, methionine and cysteine levels were reduced in hypertensive patients. Recently, the redox state of sulfur-containing amino acids has emerged as potential diagnostic marker of cardiovascular health. Metabolomic studies have revealed a shift in thiol/disulfide ratio toward oxidized forms and overproduction of thiyl radicals in hypertensive patients. Although accumulating evidence confirms that sulfur-containing amino acids are essential for the maintaining of redox homeostasis and blood pressure control, their hypotensive and antioxidant properties have been primarily demonstrated in animal studies. While several groups are developing new targeted and triggered sulfur-based donors, standardized pharmacological interventions for hypertensive patients are largely absent and pose a challenge for future research. In this review, we summarize recent studies that investigate the role of sulfur-containing amino acids and their redox-active metabolites, including glutathione and sulfide, in blood pressure control and the development of systemic hypertension.

Staple crop vulnerability has been escalating with significant approach due to climatic variations leading to persistent salt accumulation as inimical environmental stressors, and thus endangering food security. To address this global concern, there is a need to elucidate the growth, physiological and yield responses, entailing plant salt tolerance modifications. Recent years have been advocated with studies focusing on the integration of nitric oxide (NO), however there is a need of critical decipherment on NO synthesis is regulated under salt stress conditions. With this focus, the present investigation has assessed the salt-mediated differential impacts on the plant growth, root architecture, photosynthetic pigment, carbon metabolites (carbohydrate and starch), and stomatal frequency, leading to restrained plant metabolisms in the 49 wheat genotypes. Further, the accumulation of secondary metabolites (flavonoids and phenols) was found concomitant with the improved NO biosynthesis in salt-stressed tolerant wheat genotype. To validate the involvement of endogenous NO as salt stress tolerance criterion, use of NO scavenger (cPTIO) suggests the involvement of NO in enhancing salt tolerance and stress defense metabolites mainly lignin biosynthesis, and cellulose to attain plant stress tolerance. These underlying interactions could pave the way to convey wheat tolerance for the future breeding programs.
由于气候的变化，主粮作物的脆弱性不断增加，导致盐分持续积累，成为不利的环境压力因素，从而危及粮食安全。为解决这一全球关注的问题，有必要阐明植物耐盐性改变所带来的生长、生理和产量反应。近年来的研究主要集中在一氧化氮（NO）的整合上，但需要对盐胁迫条件下一氧化氮合成的调控进行关键性的解读。有鉴于此，本研究评估了盐胁迫对 49 个小麦基因型的植物生长、根系结构、光合色素、碳代谢物（碳水化合物和淀粉）以及气孔频率的不同影响，从而导致植物代谢受限。此外，在耐盐胁迫的小麦基因型中，次生代谢物（类黄酮和酚类）的积累与 NO 生物合成的改善同时进行。为了验证内源 NO 参与盐胁迫耐受性的标准，使用 NO 清除剂（cPTIO）表明 NO 参与提高耐盐性和胁迫防御代谢物，主要是木质素的生物合成和纤维素，以实现植物的胁迫耐受性。这些潜在的相互作用可为今后的育种计划铺平道路，提高小麦的耐受性。

Peripheral artery disease (PAD) is a circulatory disorder caused by atherosclerosis, leading to the narrowing or blockage of peripheral arteries, often affecting the arteries in the lower limbs. This condition can result in intermittent claudication and severe limb ischemia, significantly reducing patients' quality of life. In recent years, increasing evidence suggests that dietary interventions play a crucial role in the prevention and management of PAD, offering a safe and non-invasive treatment option. Beetroot, a natural root vegetable, demonstrates significant health benefits through its various bioactive compounds. It is rich in nitrate and betaine, which are metabolized in the body via the nitrate-nitrite- nitric oxide (NO) pathway, increasing the bioavailability of NO. NO is an important vasodilator that can improve blood flow and lower blood pressure. Additionally, the active compounds in beetroot may further enhance its health effects by altering the activity of the oral microbiome. This review explores the potential therapeutic effects of beetroot juice (BRJ) in the management of PAD. The findings indicate that BRJ can improve exercise performance, lower blood pressure, improve endothelial function, enhance skeletal muscle microvascular function and central autonomic nervous system function. Based on these findings, beetroot and its rich bioactive compounds hold promise as a novel supportive therapy for improving PAD.

Cardiovascular diseases remain the leading cause of death worldwide, imposing a substantial impact on healthcare systems due to high morbidity, mortality, and associated economic costs. Nitric oxide (NO), a key signaling molecule in the cardiovascular system, plays a critical role in regulating vascular homeostasis, angiogenesis, and inflammation. Despite its therapeutic potential, direct NO delivery in the cardiovascular system is limited by its reactivity, short half-life, and poor bioavailability. The development of NO-releasing nanomaterials addresses these challenges by enabling controlled, targeted, and sustained NO delivery, mitigating systemic toxicity and improving therapeutic outcomes. This review provides a comprehensive overview of recent advancements in the design, functionalization, and application of NO-releasing nanomaterials for cardiovascular therapies. Key topics include the use of in vitro and in vivo models to evaluate efficacy in conditions such as myocardial ischemia-reperfusion injury, thrombosis, and atherosclerosis, as well as the role of stimuli-responsive systems and hybrid nanomaterials in enhancing delivery precision. Advances in nanotechnology, such as stimuli-responsive systems and hybrid functionalized nanomaterials for targeted delivery, have enhanced the precision and effectiveness of NO therapeutic effects for treating a wide spectrum of cardiovascular conditions. However, challenges like scalable production, biocompatibility, and integration with existing therapies remain. Future research should focus on interdisciplinary approaches to optimize these materials for clinical translation, ensuring accessibility and addressing the global problem of cardiovascular diseases.

Hemorrhagic stroke (HS) is a neurological disorder caused by the rupture of cerebral blood vessels, resulting in blood seeping into the brain parenchyma and causing varying degrees of neurological impairment, including intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). Current treatment methods mainly include hematoma evacuation surgery and conservative treatment. However, these methods have limited efficacy in enhancing neurological function and prognosis. The current challenge in treating HS lies in inhibiting the occurrence and progression of secondary brain damage after bleeding, which is a key factor affecting the prognosis of HS patients. Studies have shown that medical gas therapy is gaining more attention and has demonstrated various levels of neuroprotective effects on central nervous system disorders, such as hyperbaric oxygen, hydrogen sulfide, nitric oxide, carbon monoxide, and other inhalable gas molecules. These medical gas molecules primarily improve brain tissue damage and neurological dysfunction by regulating inflammation, oxidative stress, apoptosis, and other processes. However, many of these medical gasses also possess neurotoxic properties. Therefore, the use of medical gases in HS deserves further exploration and research. In this review, we will elucidate the therapeutic effects and study the advances in medical gas molecules in HS.
