However, constructing SERS substrates with strong Raman signal enhancement effects has been a major challenge. In this study, a gold/silver nanostars (Au/Ag NSs) islands chip was developed, leveraging the phenomenon that the SERS enhancement can be significantly improved by patterning plasmonic metals with micro/nanostructures. Compared to the SERS mapping spectrogram of the conventional homogeneous Au/Ag NSs chip, uniform and dense hot spots were formed on the surface of the island chip, which is the key to remarkable enhancement of Raman signal. Both chips were functionalized with 4-mercaptophenylboronic acid (4-MPBA) for the quantitative detection of H₂S. The islands chip displays 1.6 folds and 2 orders higher blank Raman signal intensity and a limit of detection (LOD) for H₂S than conventional homogeneous SERS chips, respectively. The islands chip is also used for on-line monitoring of spoilage in high-protein foods. The detection ranges for H₂S were 2 × 10⁻⁸ M – 2 × 10⁻³ M, with a LOD of 1.9 nM. This sensing strategy provides not only a novel approach for on-ling gaseous hazards detection for food spoilage but also a potential possibility for monitoring gas molecules in the environment.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"52 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results showed that both steaming and boiling resulted in higher sensory scores for hardness (7 and 7, both moderately soft), colour (8 and 9, both light yellow), texture (8 and 5, less than 10% and 40% crack open), and smell (7 and 5, mildly sweet fragrance and musty scent) compared to the roasting (all <i>p</i> &lt; 0.05). Although steaming was particularly effective in preserving the original colour of the raw jackfruit seeds with the lowest <i>Δ</i><i>E</i> of 5.72, boiling maintained better colour attributes with higher lightness and yellowness values (90.75 and 8.37). Analysis of textural properties showed that steaming, boiling, and roasting led to a moderate reduction in hardness and springiness compared to raw samples (all <i>p</i> &lt; 0.05), which are favorable for jackfruit seeds because it resulted in a tender texture with a subtle bounce when bitten. Roasting also yielded partially gelatinized seeds (lower gelatinization compared to boiling and steaming, <i>p</i> &lt; 0.05) that maintained a balance between firmness and tenderness and presented with a pleasant bite with a slight crunch. In addition, roasted jackfruit seeds demonstrated the greatest capacity to inhibit lipase activity (all <i>p</i> &lt; 0.05), an enzyme essential for fat digestion and absorption, highlighting their significant potential for use as a weight loss supplement. Principal component analysis of 22 different factors ranked the overall quality of processed jackfruit seeds in the following order: roasting &gt; steaming &gt; boiling.

Understanding their adaptive traits can aid breeding programs target enhanced resilience and productivity, especially as we are facing important climate and agriculture challenges. To this aim the genomic architecture of 480 goats belonging to five breeds (i.e., Saanen [SAA], Camosciata delle Alpi [CAM], Murciano-Granadina [MUR], Maltese [MAL], Sarda [SAR]) reared in the Sardinia Island were genotyped and their genomic architecture evaluated to find molecular basis of adaptive traits. Inbreeding, runs of homozygosity (ROH) and runs of heterozygosity (ROHet) were identified. Finally, candidate genes in the ROH and ROHet regions were explored through a pathway analysis to assess their molecular role. In total, we detected 10,341 ROH in the SAA genome, 11,063 ROH in the CAM genome, 12,250 ROH in the MUR genome, 8,939 ROH in the MAL genome, and 18,441 ROH in the SAR genome. Moreover, we identified 4,087 ROHet for SAA, 3,360 for CAM, 2,927 for MUR, 3,701 for MAL, and 3,576 for SAR, with SAR having the highest heterozygosity coefficient. Interestingly, when computing the inbreeding coefficient using homozygous segment (FROH), SAA showed the lowest value while MAL the highest one, suggesting the need to improve selecting strategies to preserve genetic diversity within the population. Among the most significant candidate genes, we identified several ones linked to different physiological functions, such as milk production (e.g., DGAT1, B4GALT1), immunity (GABARAP, GPS2) and adaptation to environment (e.g., GJA3, GJB2 and GJB6). This study highlighted the genetic diversity within and among five goat breeds. The high levels of ROH identified in some breeds might indicate high levels of inbreeding and a lack in genetic variation, which might negatively impact the animal population. Conversely, high levels of ROHet might indicate regions of the genetic diversity, beneficial for breed health and resilience. Therefore, these findings could aid breeding programs in managing inbreeding and preserving genetic diversity.","PeriodicalId":14928,"journal":{"name":"Journal of Animal Science and Biotechnology","volume":"36 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these states have rarely been quantitatively described, limiting understanding of impacts on ecosystem services, biodiversity, and fire behaviour. Using aerial LiDAR data, we quantified multiple structural attributes of ‘reference’ and ‘alternative’ forest states across three structurally diverse forest types, dominated by either obligate seeder or resprouter eucalypt trees. Alternative forest states which have persisted for at least 70 years, arose from short-interval wildfires in the early 20th century; while return intervals of reference states were considered within the ecological tolerance. Results indicate significant transformation across all three forest types. Alternative states were structurally distinct and more homogeneous than reference states. Homogenisation was evident in mean and maximum canopy height, light penetration index, rumple index, and LiDAR leaf area index. Depending on forest type, percentage cover of large overstory trees was significantly lower in alternative states (4–7 %) compared with reference states (39–50 %). Mean height was between 71 % and 78 % lower, and maximum height 52–60 % lower than reference states. Measures of horizontal structural heterogeneity including rumple index (canopy ‘roughness’) and foliage height diversity were lower, suggesting a simplified canopy surface in alternative states, with scattered emergent overstory trees, and decreased vertical differentiation of strata. Moreover, the LiDAR-derived leaf area index and light penetration index indicated a more open environment than reference states. Our findings suggest short-interval wildfires drive widespread and persistent homogenisation of forest structure, potentially degrading ecosystem functions that support biodiversity and ecosystem services.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"584 ","pages":"Article 122580"},"PeriodicalIF":3.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143529749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the impacts of different fertilization strategies conventional chemical fertilization (CT), partial organic substitution (MT), and fully organic fertilization (OT)—on P transport, rice yield, and environmental risks over a seven-year period. Using a combination of field experiments and HYDRUS-1D simulations, we analyzed how agricultural management influences P distribution in the soil profile, crop uptake, and leaching potential. Our results showed that HYDRUS-1D model could accurately simulate P transport, with RMSE range from 0.024 to 0.031 mg L⁻¹ during calibration in 2012 and 0.053–0.073 mg L⁻¹ during validation in 2018. The results demonstrated that the MT treatment achieved the highest P use efficiency, maintaining rice yields comparable to CT while significantly reducing P leaching into deeper soil layers. In contrast, OT resulted in excessive P buildup in the topsoil, increasing leaching risks. Model simulations further show that an increase in temperature by up to 2°C had minimal effects on P transport, suggesting that proper P fertilization strategies are more critical than temperature variability for minimizing environmental pollution. According to model simulation, the recommended P application rates for CT, MT, and OT are 64.18, 55.86, 50.97 kg hm⁻² respectively, with MT providing the best balance between crop productivity and environmental sustainability.

This study was conducted on a training smallholder dairy farm in Phnom Penh, Cambodia, from January 2023 to July 2023. Trained veterinarians aseptically collected quarter milk samples from all milking cows (<i>n</i> = 21) every 2 weeks until the end of the study, accounting for 3–16 times of milk collection per cow based on their period of lactation. All collected milk samples (<i>n</i> = 812) were cultured, and subsequently, all bacterial colonies were identified using a MALDI-TOF mass spectrometer. An IMI episode is defined as a sequence of consecutive isolates of a specific bacterium from the same quarter. The duration of an episode is the time between the new IMI and its cure. Two types of IMI were defined as transient IMI and chronic IMI that lasted for 28 days or more.
