Phytoene synthase (PSY) is a multimeric enzyme that serves as the first enzyme in carotenoid synthesis within plant tissues and plays a crucial role in the production of carotenoids in plants. To understand the function of the PSY gene in Panax japonicus C. A. Meyer. fruit, the gene’s transcript was obtained by analyzing the transcriptome sequencing data of Panax japonicus fruit. The CDS sequence of the gene was cloned from Panax japonicus fruit using the RT-PCR cloning technique and named PjPSY1, which was then subjected to biosynthetic analysis and functional verification. The results showed that the open reading frame of the gene was 1269 bp, encoding 423 amino acids, with a protein molecular mass of 47,654.67 KDa and an isoelectric point (pI) of 8.63; the protein encoded by these amino acids was hydrophilic and localized in chloroplasts, and its three-dimensional structure was predicted by combining the pymol software to annotate the N site of action and active centre of the protein. Phylogenetic analysis demonstrated that PjPSY1 had the closest affinity to DcPSY from Daucus carota. Overexpression of PjPSY1 led to a significant increase in the content of carotenoid-related monomers in Arabidopsis thaliana, with Violaxanthin being synthesized in transgenic Arabidopsis thaliana but not in wild-type Arabidopsis thaliana. The PjPSY1 clone obtained in this study was able to promote carotenoid synthesis in the fruits of Panax japonicus, revealing that the mode of action of PjPSY1 in the carotenoid biosynthesis pathway of Panax japonicus fruits has a positive regulatory effect.

During fruit ripening in Capsicum species, substantial amounts of carotenoids accumulate in the pericarp. While the carotenoid biosynthesis pathway in Capsicum species has been extensively investigated from various angles, the transcriptional regulation of genes encoding carotenoid biosynthetic enzymes remains less understood in this non-climacteric horticultural crop compared to tomato, a climacteric fruit. In the present study, we investigated the function of the NAM, ATAF1/2 or CUC2 81 (CaNAC81) transcription factor gene. This gene was selected through RNA-Seq co-expression analysis based on the correlation between expressed transcription factor gene profiles and those of carotenoid structural genes. To determine its role in regulating the expression of biosynthetic-related carotenogenic genes, we performed Virus-Induced Gene Silencing (VIGS) assays in the Serrano-type C. annuum ‘Tampiqueño 74’. Fruits from plants infected with a pTRV2:CaNAC81 construct (silenced fruits) exhibited altered carotenoid pigmentation accumulation, manifested as yellow-orange spots, in contrast to fruits from non-agroinfected controls (NTC) and fruits from plants infected with the empty TRV2 construct (red fruits). Quantitative real-time PCR (qPCR) assays confirmed decreased transcript levels of CaNAC81 in fruits displaying altered pigmentation, along with reduced transcription of the PSY gene, which encodes the carotenoid biosynthetic enzyme phytoene synthase (PSY). High-performance liquid chromatography (HPLC) analysis revealed a distinct carotenoid pigment accumulation pattern in fruits from plants showing silencing symptoms, characterized by low concentrations of capsanthin and zeaxanthin and trace amounts of capsorubin, compared to control plants (NTC). These findings suggest the involvement of CaNAC81 in the regulatory network of the carotenoid biosynthetic pathway in chili pepper fruits. Full article

Background and Objectives: Acceptance and commitment therapy (ACT) enhances psychological flexibility by fostering acceptance of thoughts and emotions, promoting mindfulness practices, and encouraging engagement in value-based actions. These processes have been associated with improvements in mental health and social functioning, with accumulating evidence supporting ACT’s efficacy across various psychiatric disorders. This systematic review aimed to evaluate current evidence on ACT interventions for reducing psychiatric symptoms and enhancing social functioning and interpersonal relationships in adults with psychiatric conditions. Materials and Methods: A comprehensive search was conducted across PubMed, Web of Science, the Cochrane Library, and Embase for studies published between 2014 and 2024. The review protocol was registered on the Open Science Framework (OSF; registration ID: 2ZAGT). Results: Seventeen studies met the inclusion criteria; however, the evidence base remained fragmented, with most psychiatric diagnoses represented by only one or two studies. The reviewed studies exhibited several methodological limitations, including small sample sizes, lack of randomization and blinding, high risk of bias, reliance on subjective outcome measures, and inadequately designed or absent control groups. Despite these limitations, ACT was associated with beneficial effects in conditions such as post-traumatic stress disorder (PTSD), insomnia, psychosis, and autism spectrum disorder, particularly in reducing experiential avoidance, enhancing mindfulness, and promoting long-term improvements in emotional regulation and life satisfaction. Conclusions: Due to the limited number of studies per diagnosis, significant methodological weaknesses, and the lack of high-quality controlled trials, this review cannot provide strong evidence for the efficacy of ACT in improving social functioning among adults with psychiatric disorders. The heterogeneity and overall low quality of the available literature highlight the urgent need for further large-scale well-controlled studies. Full article

Seoul systematically removed all graveyards that once lay within the city and its surrounding areas, a phenomenon notably distinct from urban development patterns in other parts of the world. After the Korean War, refugees and migrants poured into the devastated capital. In this postwar environment, cemeteries—traditionally sites of mourning and death—transformed into spaces of survival for displaced populations. With the military demarcation line preventing their return home, refugees began to envision their lost hometowns as “absent places”: unattainable utopias, idealized lands where all beauty resides—the very origin and endpoint of life. In contrast, Seoul, where they were forced to settle, became a “dystopia,” stripped of sanctity. Over time, however, the next generation reinterpreted this dystopia, gradually transforming it into a heterotopia. As Seoul’s urban landscape expanded, this heterotopia evolved into a Christian paradise. The second generation, having never experienced the trauma of displacement, found the newly constructed city comfortable and secure. Reinforced concrete buildings and asphalt roads became symbolic of paradise. The development of Gangnam—famously captured in Psy’s global hit “Gangnam Style”—represents a belated cultural revolution among younger generations in modern South Korea and exemplifies the transformation into a concrete paradise.

The WRKY gene family is essential for controlling a variety of plant physiological functions, yet the involvement of specific WRKY members in pigment biosynthesis and accumulation in Camellia chekiangoleosa remains unexplored, particularly in anthocyanins and carotenoids, which play crucial roles in the pigmentation of C. chekiangoleosa. This study systematically identified 87 WRKY genes across 15 chromosomes in C. chekiangoleosa through bioinformatic approaches. Further structural and phylogenetic analyses of these TFs enabled their classification into six different subgroups. WRKY family expansion was shown to be mostly driven by tandem duplication. W-box elements, which can be binding sites for WRKY transcription factors, were present in a number of biosynthetic genes in the pigment production pathway. Yeast one-hybrid assay confirmed that five WRKY transcription factors (CchWRKY15/24/33/47/76) directly bind to the promoter regions of two key biosynthetic genes, CchPSY1 and Cch4CL1. Intriguingly, among the five WRKYs tested, the expression levels of CchWRKY15, CchWRKY33, and CchWRKY47 showed the strongest positive associations with flavonoid accumulation (p < 0.05, Pearson correlation analysis).These findings provide novel insights into the evolutionary patterns, transcriptional regulation, and functional characteristics of CchWRKYs, while elucidating their possible regulatory mechanisms in the fruit coloration of C. chekiangoleosa.

Background/Objectives: The experience sampling method (ESM) is a structured data collection method in which participants respond to randomly timed acoustic alerts while engaging in their daily activities. It allows patients to assess their mood, context and pain levels. This study aimed to evaluate the opinions of patients who underwent surgery on the perioperative use of a digital ESM tool. Methods: The Psymate app version 1.6.15 (ESM device) generated 10 short reports (acoustic alerts) at semi-random times each day for patients who underwent total knee arthroplasty (TKA). The short report, consisting of 23 items, contained questions about mood, context and pain. At the end of the study, patients’ opinions about the app were collected through a standardized questionnaire covering multiple subtopics. Feedback was analyzed using descriptive statistics. Results: Of the 40 patients scheduled for TKA, 31 participated in the evaluation. The app received an average user-friendliness rating of 8.3 out of 10. Some patients express dissatisfaction with the frequency (n = 10) and noise (n = 14) of the notifications. Additional analyses suggest that higher pain levels may reduce the likelihood of completing the short report. Conclusions: This is the first study to evaluate postoperative patients’ opinions on the use of a digital ESM app. The PsyMate app received satisfactory ratings across all subtopics, although patients identified areas for improvement.

Phaeodactylum tricornutum is rich in bioactive substances, rendering it valuable in nutrition and medicine. Epigenetic editing mediated by human RNA demethylase FTO can significantly increase the yields of rice and potato and offers significant potential for the genetic breeding of microalgae. This study aimed to enhance the production of certain metabolites in P. tricornutum via FTO-mediated epigenetic editing. Phenotypic analysis revealed that transgenic P. tricornutum exhibits significantly reduced RNA m⁶A modification levels and faster growth, producing markedly higher levels of lipids, proteins, and carotenoids than the wild type. Transcriptome analysis revealed 1009 upregulated genes and 378 downregulated genes. KEGG analysis demonstrated the upregulated expression of multiple key enzymes involved in long-chain fatty acid synthesis (e.g., ACSL, fabF, and fabG), carotenoid synthesis (e.g., crtQ, PDS, and PSY1), and amino acid synthesis (e.g., dapF, glyA, and aroK) in transgenic P. tricornutum, consistent with our phenotypic results. These results indicate that FTO can promote growth and increase the bioactive compound content in P. tricornutum by regulating the m⁶A modification of RNA, and further suggest that FTO has the potential to serve as a new tool for the epigenetic editing of microalgae.

This study aimed to characterize carotenoid profiles and unravel the genetic mechanisms underlying flesh color variation in white and yellow-fleshed peaches, with a focus on the hybrid cultivar ‘ZY29’ derived from two white-fleshed parents (‘Yulu’ and ‘Hujing Honey Dew’). Using UPLC-APCI-MS/MS, we quantified carotenoids in the pericarp (exocarp) and flesh (mesocarp) of parental and hybrid fruits. Results showed that ‘ZY29’ accumulated significantly higher levels of β-carotene and lutein compared to its white-fleshed parents. Transcriptome analysis revealed upregulation of carotenoid biosynthesis genes (PSY, LCYB, and ZDS) and downregulation of the carotenoid cleavage gene CCD4 in ‘ZY29’, explaining enhanced carotenoid accumulation. Integrative metabolome-transcriptome analysis identified core regulatory networks associated with metabolic shifts, including transcription factors (MYB and WRKY). These findings provide novel insights into the molecular basis of yellow flesh formation in peaches, offering potential targets (PSY and LCYB) and metabolic markers (β-carotene and lutein) for breeding nutritionally enriched cultivars. These findings contribute to a better understanding of the genetic factors and parental regulatory mechanisms involved in the formation of yellow flesh color in peaches. Our results have important implications for breeding new peach varieties with desirable color and nutritional qualities and may provide valuable insights for future research in this area.

Background/Objectives: Schizophrenia is a severe psychiatric disorder, with onset typically occurring in late adolescence or early adulthood. Early identification of psychotic symptoms, especially those occurring before age 12, has been linked to better long-term outcomes. This study aims to assess the presence of psychotic spectrum symptoms before the age of 12 in adult schizophrenia patients and explore their clinical implications for early detection and intervention. Methods: This retrospective, observational study included 170 adult patients diagnosed with schizophrenia, confirmed by the SCID-5. Patients were recruited from the University of Siena Medical Center and completed the modified lifetime version of the Psychotic Spectrum Self-Report (PSY-SR) questionnaire, which assessed the onset of specific psychotic symptoms before and after age 12. Symptom severity was evaluated using the Brief Psychiatric Rating Scale (BPRS) and the Clinical Global Impression Scale (CGI). This study also examined the impact of the duration of untreated psychosis (DUP) on symptom severity. Results: In our cohort, 21% of patients exhibited prodromal symptoms before age 12 (95% CI: 15–27%). Prodromal symptoms were linked to a 9.53-point increase in the BPRS scores (p = 0.0478) and a 0.50-point increase in the CGI scores (p = 0.0347). The age of symptom onset negatively correlated with the BPRS scores (p < 0.0001), with each year of delay resulting in a 1.33-point decrease. The DUP correlated significantly with both the BPRS (ρ = 0.97) and CGI scores (ρ = 0.94). The multivariate analysis revealed that a longer DUP was associated with significant increases in both scores: a 27.16-point increase in the BPRS (p < 0.0001) for a moderate DUP and a 67.51-point increase (p < 0.0001) for a severe DUP. The CGI scores increased by 1.11 points with a moderate DUP and 3.17 points with a severe DUP (p < 0.0001). However, the interaction between the DUP and prodromal symptoms at age 12 was not significant, indicating similar impacts of the DUP regardless of early symptom onset. Conclusions: The results support the critical importance of early detection and intervention in schizophrenia. Early psychotic spectrum symptoms, particularly those occurring before age 12, are significant predictors of later severity and functional impairment. This study underscores the value of screening tools like the PSY-SR for identifying prodromal symptoms and facilitating timely intervention. Our findings highlight the need for the early identification of psychotic symptoms, particularly in at-risk populations, to improve long-term outcomes. Intervening before the onset of full-blown psychosis may reduce the severity of schizophrenia and promote better clinical outcomes. Full article

Pomegranate (Punica granatum L.) is an important economic tree, possessing both edible and ornamental value. Flower color is an important ornamental trait of pomegranate, but the color formation pattern and related molecular mechanisms of pomegranate petals are still unclear. In this study, we conducted physiological, transcriptomic, and metabolomic studies on the petals of Tunisia and White pomegranate varieties during the blooming stage. The results showed that compared to White petals, the contents of anthocyanin, carotenoid, and sucrose in Tunisia petals were significantly increased, while the flavonoid content was significantly decreased. Through RNA-seq, 23 DEGs were identified in the anthocyanin synthesis, and 3 DEGs were identified in the carotenoid synthesis. Transcription factor genes such as MYB, bHLH, WRKY, and MADS were identified as key candidates for regulating anthocyanin metabolism. Metabolomic analysis revealed that eight DEMs are associated with anthocyanin synthesis and three DEMs are associated with carotenoid synthesis. In addition, caffeic acid and its derivatives were significantly upregulated in Tunisia petals. In summary, we propose the following hypothesis: the accumulation of anthocyanins and carotenoids is the reason for the red color of Tunisian petals, and the upregulation of structural genes, including PAL, C4H, 4CL, CHS, CHI, F3H, F3′H, DFR, ANS, PSY, and LCYB, leads to an increase in their content. Transcription factor genes such as MYB, bHLH, bZIP, MADS, and WRKY may also play a positive role in anthocyanin accumulation. The research results provide a basis for the theory of pomegranate petal color formation. Full article

Pumpkin (P) production in Santiago del Estero, Argentina, is of high quality. The product is sold whole and fresh, and is traditionally consumed after being cooked in water. Due to its pleasant flavor (semi-sweet), it is widely accepted among consumers, being a potentially versatile product to be consumed fresh or minimally processed (MP). Processing increases food’s susceptibility to microbial spoilage, making it necessary to use sanitizers. In this work, the effect of different application methodologies at different concentrations of rosemary essential oil (REO) on the sensory characteristics and microbiological quality of grated P was evaluated. The product was washed, sanitized, cut, peeled, grated and centrifuged, and then REO was superficially incorporated in two concentrations (4 and 8 μL/mL), applied in three ways: sprayed (TA), immersion (TI) and by strips embedded in EO being adhered to the storage container (TV). The product was subsequently stored at 5 °C in sealed polypropylene bags of 35 μm. In addition, an immersion treatment with NaClO-100 ppm-3 min and a control without any additive were included. Samples were taken at 24 h and 8 days of storage, evaluating mesophilic aerobic microorganisms (MA), psychrophilic (Psy), enterobacteria (E) and mold and yeasts (MY). Sensory evaluation was carried out by trained judges, determining that aroma and flavor were the critical attributes for acceptability. At the end of storage, microbiological analysis showed that REO treatments presented levels of 10⁷ CFU/g, similar to NaCLO treatment, except TI with both concentrations, which was more effective in inhibiting the development of Psy and MY. Regarding aroma evaluation, at 8 days all treatments were acceptable, with the exception of TI and TV (8 μL/mL), while for flavor all treatments were acceptable with the exception of TI for both concentrations. Therefore, the application of TA and TV treatments at the lowest concentration could be considered for further studies to increase the shelf life of MP P. Full article

Background/Objectives: Despite the importance of the second victim phenomenon for healthcare systems, there is limited research on Italian healthcare providers. We assessed emotional distress in individuals impacted by an adverse event using the Withstand-PSY Questionnaire (WS-PSY-Q). Additionally, we aimed to identify potential risk factors for anxiety and depression. Methods: A cross-sectional online survey of 284 participants. Measures included the WS-PSY-Q, Beck Depression Inventory-II (BDI-II), and State-Trait Anxiety Inventory (STAI-Y). Descriptive analyses and seemingly unrelated regression, jointly estimating anxiety and depression, were conducted using Stata (version 18). Results: Fifty-nine percent of the participants tested positive for anxiety (WS-PSY-Q anxiety subscale ≥ 16), thirty-seven percent for depression (WS-PSY-Q depression subscale ≥ 22), and thirty-five percent for both. In the final model, anxiety symptoms following the adverse event were associated with pre-event anxiety levels (p < 0.01), seeking psychological help (p < 0.05), self-perceived responsibility (p < 0.01), severity of the adverse event for the patient (p < 0.05), and punitive workplace climate (p < 0.05). Correlates of post-event depressive symptoms included pre-existing depression (p < 0.01), self-perceived responsibility (p < 0.01), severity of the impact of the adverse event (p < 0.01), punitive or neutral workplace climate (p < 0.05), and seeking psychological help (p < 0.01). Conclusions: This study adds to the growing understanding of the mental health difficulties that healthcare workers in Italy encounter after adverse events, addressing both individual and systemic risk factors. Proactive implementation of mental health measures for healthcare workers could foster their well-being after adverse events and promote a stronger, more just organizational culture. Full article

Auricularia heimuer is a valuable traditional Chinese fungus used as food and medicine. Hei29 is a strain derived from wild A. heimuer through systematic domestication and selection. It has been the primary A. heimuer variety in Northeast China for 30 years and offers the advantages of high yield, good commercial property, and stable traits. This study used protoplast nucleation on Hei29 to produce two amiable and paired monokaryons, Hei29-D1 and Hei29-D2. The genome of Hei29 was sequenced utilizing the Illumina PE150 and PacBio Sequel sequencing platforms. Hei29-D1 and Hei29-D2 had genomic sizes of 47.54 Mb and 47.49 Mb, GC contents of 56.95% and 56.99%, and an N50 of 2.37 Mb and 4.28 Mb, respectively. Hei29’s genome possessed two phytoene synthase (PSY) protein genes, one of which—PSY encoded by g894—has a transmembrane domain. The phylogenetic tree showed that Hei29 shared the closest evolutionary relationship with Auricularia subglabra TFB-10046 SS5. Collinearity analysis showed that the correlation between the two monokaryons was as high as 90.81%. Cluster analysis revealed that Hei29 contains 12,362 core genes, 223 unique genes in Hei29-D1, and 228 unique genes in Hei29-D2. This study is the first to sequence two related and paired monokaryons from A. heimuer, which is critical for fully understanding the genetic composition and information of the characteristic strain of A. heimuer in Northeast China. It establishes the data and theoretical foundation for gene mining, usage, and molecular breeding. It further promotes the genetic breeding and active substance utilization of A. heimuer. Full article
