Oyster mushrooms are recognized for their health-promoting phenolic compounds, which contribute to significant antioxidant properties. Efficient extraction and accurate quantification of these compounds are essential for advancing their application in nutraceuticals. This study aimed to develop and validate a microwave-assisted extraction (MAE) method for profiling phenolic compounds in a diverse selection of oyster mushrooms (Pleurotus spp.) sourced from multiple geographical regions. Using the Box-Behnken design and response surface methodology, three primary factors—solvent composition (0–30 % methanol in water), solvent-to-sample ratio (10:1–20:1 mL g⁻¹), and temperature (40–70 °C)—were optimized. The optimal extraction conditions identified were pure water as a solvent, a 17.5:1 solvent-to-sample ratio, and a temperature of 44 °C, with a 10-min extraction time. The validated MAE method demonstrated high accuracy (>85 % recovery) and precision (CV <10 %), meeting analytical standards. Seven phenolic compounds—p-coumaric acid, t-cinnamic acid, p-hydroxybenzaldehyde, p-hydroxybenzoic acid, quercetin-3-glucoside, gallic acid, and vanillic acid—were effectively extracted and quantified using ultra-performance liquid chromatography with photodiode array detection. Application of this method across oyster mushroom samples from different geographical sources revealed significant variation in phenolic compound concentrations, with Pleurotus pulmonarius exhibiting the highest level of gallic acid at 433.90 ± 7.77 μg g⁻¹ (DM) and Pleurotus ostreatus var. Florida showing the highest concentration of ρ-hydroxybenzaldehyde at 199.68 ± 1.06 μg g⁻¹ (DM). This optimized MAE method proves to be a reliable tool for phenolic profiling in diverse oyster mushroom varieties, supporting potential applications in functional food, pharmaceutical, and nutraceutical industries.

This study examines the intricate interplay between nutritional claims and consumer purchasing behaviour in the Italian rusk market. Rusks, obtained by double baking sliced loaf bread, are a staple of the Italian breakfast, generating annual revenues of EUR 225 million. With the growing focus on more health-conscious food choices, expecially after COVID-19, health-related claims on food labels have a greater impact on consumers. Utilizing the hedonic pricing method, the study decomposed rusk market value based on specific product characteristics, revealing how quality attributes and nutritional aspect influence price. Data collected from major retail chains yielded 1438 observations, showing a positive correlation between price and factors such as brand, format, ingredients formulations and nutritional or sustainability claims. Results show that among analyzed regulated nutritional claims: "no added sugars," "high in protein," and "low salt content" exhibit the highest premium price, highlighting consumers' willingness to pay more for products perceived as healthy, as well as for enriched products or those made with alternative flours. Conversely, in a very heterogeneous context and a highly competitive market, reduced ingredient formulations and traditional recipes result in discount prices. The research demonstrates that clear and transparent health-related communication promotes informed purchases. This study suggests that producers adopting differentiation strategies focused on nutritional quality and the use of food claims can enhance product appeal and positively influence consumer purchasing decisions, thereby increasing their market share in a dynamic market.

Postharvest has vital impact on production of desired compounds in some medicinal plants. Iris germanica L. rhizome with the trade name of orris root, should be kept for 3–5 years, to produce irones from triterpene iridals. Irones have an important role in food, pharmaceutical and perfumery industries. Here, we evaluated the effect of rhizome type (whole and sliced) and drying methods including infrared, microwave, oven, vacuum-oven, shade and sun drying on volatile constituents of orris root, especially on irone content. The effect of these treatments on drying time (DT), phytochemical and antioxidant capacity of orris root has been also investigated. Rhizome type and drying methods significantly affect on DT (P < 0.01). Lowest DT was in Microwave and whole rhizome with 1:4

. Interestingly, microwave drying not only reduced the time of drying but also, increased the irones content compared to the fresh samples. The negligible amount of cis-α-irone and cis-γ-irone in fresh sample (0.2 %), reached to more than 90 % in whole rhizome by microwave drying. In almost all methods, irone content was significantly higher in whole rhizome rather than the sliced rhizomes. However, the highest TPC (110.29 mg GAE/g DWP), TFC (70.344 mg QUE/g DWP) and antioxidant activity (DPPH: 104.988 mg TBHQ/g DWP) was observed in sun dried whole sample. In conclusion, microwave is the best method for producing irone compounds and sun drying could be the best method to keep the phenolic and antioxidant compounds in I. germanica.

Hypertension (HTN) remains the major and modifiable risk factor of various cardiovascular complications and target organ damage. HTN is often asymptomatic until it reaches a severe stage, making it a “silent killer”. Despite the ongoing advancements in pharmacological treatment, the escalating prevalence of HTN (≈25 %) around the globe has urged the need to implement non-pharmacological interventions to manage HTN and its related complications. Managing hypertension at earlier stages is the first and foremost step to prevent its risk and progression to later stages. Incorporating dietary and lifestyle modifications may be an effective approach owing to their synergistic action with the antihypertensive drugs to mitigate HTN. Hence, non-pharmacological approaches can be used as an adjunctive management strategy to control HTN, minimize dose of antihypertensive drugs and its related side effects. Hereby, this review explores various risk factors of HTN and discusses the crucial roles of macro/micronutrients, dietary supplements and healthy eating patterns in preventing and managing HTN. Furthermore, this review also mentions the effects of anti-nutritional factors and nutrigenomics on HTN. The impacts of healthy lifestyle modifications including smoking cessation, regular sleeping patterns, stress management, exercise, reducing alcohol consumption and limiting exposure to particulate matter on HTN are also discussed in this review. This information may be helpful in designing a holistic management and treatment approach to reduce the burden of HTN and address the challenges associated with pharmacological treatment. However, more studies are required to investigate the long-term efficacy and side effects of non-pharmacological interventions in primary care settings and assess their risk-to-benefit ratio.

高血压（HTN）仍然是导致各种心血管并发症和靶器官损伤的主要风险因素，而且是可以改变的风险因素。高血压在发展到严重阶段之前往往没有症状，因此成为 "无声杀手"。尽管药物治疗不断进步，但全球高血压患病率（≈25%）的不断攀升促使人们需要采取非药物干预措施来控制高血压及其相关并发症。在早期阶段控制高血压是预防其风险和向后期发展的首要步骤。调整饮食和生活方式可能是一种有效的方法，因为它们与降压药物具有协同作用，可减轻高血压。因此，非药物疗法可作为控制高血压的辅助管理策略，最大限度地减少降压药物的剂量及其相关副作用。因此，本综述探讨了高血压的各种风险因素，并讨论了宏量/微量营养素、膳食补充剂和健康饮食模式在预防和控制高血压方面的重要作用。此外，本综述还提到了抗营养因素和营养基因组学对高血压的影响。本综述还讨论了健康生活方式的改变对高血压的影响，包括戒烟、规律的睡眠模式、压力管理、运动、减少饮酒和限制接触颗粒物质。这些信息可能有助于设计全面的管理和治疗方法，以减轻高血压的负担，并应对药物治疗带来的挑战。然而，还需要进行更多的研究，以调查非药物干预措施在初级保健环境中的长期疗效和副作用，并评估其风险效益比。

The objective of this work was to study the angiotensin-I-converting enzyme (ACE) inhibitory (ACEi) activity, inhibition mechanism, and ameliorating functions of SLPY, QYPPMQY and EYEA on HUVECs damaged by oxidative stress. The results indicated that SLPY, QYPPMQY and EYEA could significantly inhibit ACE activity with IC₅₀ values of 0.3715, 0.2903 and 0.3375 mg/mL, respectively; the affinity of SLPY, QYPPMQY and EYEA with ACE was −8.1, −9.9, and −8.3 kcal/mol, respectively, which is mainly due to the hydrophobic interaction and hydrogen bonding between peptide and ACE. Moreover, SLPY, QYPPMQY and EYEA could significantly improve the viability of H₂O₂-damaged HUVECs. The mechanism showed that SLPY, QYPPMQY and EYEA could activate the Keap1/Nrf2 pathway in HUVECs through significantly up-regulating Nrf2 protein expression and level in the nucleus (P < 0.05), which subsequently improved the activity of downstream proteases, increased the NO production, and reduced the levels of ROS, MDA and LDH. Moreover, molecular docking results illustrated that SLPY, QYPPMQY and EYEA could regulate Keap1/Nrf2 pathway by non-competitive inhibition model. Then, SLPY, QYPPMQY and EYEA could ameliorate hypertension via significantly inhibiting ACE activity and effectively protecting HUVECs against oxidative damage, and these results provide theoretical support for developing health products for curing hypertension and its closely related cardiovascular diseases.

Agricultural cooperatives are widely regarded as effective institutions for supporting smallholder farmers, reducing poverty, and improving food security. However, empirical evidence varies with mixed findings across different contexts. This study used a primary data of 820 farm households to examine the relationship between membership of water user association (WUA) and food security, using a quasi-experimental research design. The findings show that WUA membership is significantly influenced by factors including age, marital status, access to extension services, participation in supplementary irrigation (SI) and drought index insurance (DII) initiatives, farm size, and an asset aspiration gap. The results further indicate a positive association between WUA participation and household food security. These findings suggest that rural development policies should focus on strengthening existing WUAs and fostering the establishment of new ones through inclusive approaches that address food insecurity.

Patterns of systemic problems in Ghana's poultry value chain: A group model building approach

Ghana's poultry sector faces different interrelated systemic challenges, often diagnosed in isolation, leading to interventions that neglect unintended consequences across the value chain. Consequently, a holistic prognosis of the impact of these systemic problems that considers the different facets of the poultry industry is required.

This paper aims to examine the system archetypes emerging from the inherent industry-level and farm-level problems in Ghana's poultry sector. Adopting a participatory group model building process, causal loop diagrams and feedback loop analyses were applied to understand the interacting factors in four systemic problems prioritised by stakeholders in Ghana's poultry value chain. Four causal loop diagrams were mapped for these systemic problems; (i) inadequate research funding (ii) low adherence to biosecurity measures at the farm level; (iii) lack of access to credit; and (iv) the competition from cheap imports of poultry meat products.

The findings highlight three emerging problem archetypes. First, the underachievement archetype, specifically the limit to growth, emerges when technology adoption due to increased research funding interacts with the non-adherence to biosecurity measures as a cost-cutting strategy at the farm level. Second, the out-of-control archetype emerges when the misuse of antimicrobials due to the non-adherence of biosecurity measures interacts with the industry's collapse and the consequential surge in chicken imports into the country. Third, the relative achievement archetype emerges from the reinforcing feedback loop which centres around the surge in imported chicken as a response to looming food insecurity concerns arising from insufficient domestic supply. The “success to the successful” archetype is thus created, where importers in the poultry value chain become more prosperous at the expense of the entire industry.

The paper presents solutions to the emerging problem archetypes, providing stakeholders with a chance to evaluate the unintended consequences of proposed government policies aimed at rejuvenating local poultry production.

Trace metal contamination in aquatic ecosystems poses a significant environmental and public health challenge, especially in developing countries like Ethiopia. This study evaluates the concentrations, potential sources, and health risks of trace elements in Lakes Tana and Hayqe, focusing on the implications for adult fish consumers. Forty fish samples were collected, cleaned, and wet-digested using standard protocols, and trace element concentrations were determined using Flame Atomic Absorption Spectrophotometry (FAAS). The findings revealed that in Lake Tana, the mean concentrations (mg/kg) of Mn (22–27), Cd (6.8–15), Pb (4.8–7.8), and Cr (11) exceeded the permissible limits set by regulatory bodies for safe consumption, while Fe (15–57), Cu (4.7–6.1), and Zn (20–25) were within acceptable limits. Similarly, in Lake Hayqe, the mean concentrations of Zn (43–48), Cd (8.5–19), Cr (0.9–12), Pb (7.0–12), and Mn (35) were above satisfactory limits, except for Fe (86–90) and Cu (4.7–7.6), which were within safe thresholds. The non-cancer risks were less than 1, while the cancer risks were within the tolerable intake values of 10⁻⁴ - 10⁻⁶, indicating less health risk for fish consumers. Statistical analyses highlighted interrelationships among trace elements and identified contamination sources, underscoring anthropogenic activities as significant contributors. These results call for comprehensive monitoring and stringent regulatory measures to curb trace metal pollution and safeguard public health. Further research should explore the broader ecological consequences of metal contamination and investigate emerging pollutants in aquatic ecosystems.

Wine flavors encompass distinct varietal, fermentation, and aging aromas, with grape variety and terroir playing a crucial role in shaping the variations in wine's aroma. The distinct geographical and climatic conditions in Xinjiang have created a unique terroir. To assess the flavor characteristics of white wines from Xinjiang, we investigated the physicochemical properties, organic acids, phenolic compounds, antioxidant activity, and aroma profiles of Chardonnay (CDW), Riesling (RLW), Gewurztraminer (GTW), Italian Riesling (IRW), Chenin Blanc (CBW), and Ecolly wines (ELW) using HPLC and HS-SPME-GC-MS techniques. The results showed that malic acid and tartaric acid were the dominant organic acids, while quercetin, rutin, and neochlorogenic acid were the most important phenolic compounds in white grapes and the wines. Among them, quercetin, neochlorogenic acid, coumaric acid, and gallic acid contributed substantially to the antioxidant activity in vitro. A total of 64 aromatic compounds were identified in white grapes, while 73 aromatic compounds were identified in the wines. Alcohols (especially isoamylalcohol and phenethyl alcohol) and esters (including ethyl caprylate and phenethyl acetate) were the main volatile compounds, and floral and fruity were typical aromas in white wines. Additionally, aldehydes and other esters may contribute to the fruity and floral flavor formation in the wines from Xinjiang, with β-damascenone potentially playing an indirect role in floral flavor formation. This study provides a theoretical foundation for enhancing the quality of white wine production in Xinjiang.
