A novel method of cardia visualization and comfort level enhancement during magnetic capsule gastroscopy via sugar-glued tether-assisted technique: a randomized pilot study inspired by a Chinese snack-making process (with video).

BACKGROUND: Magnetic capsule gastroscopy (MCG) is a non-invasive diagnostic method for the digestive tract. However, its efficiency in visualizing the gastric cardia is often compromised due to the capsule's rapid passage. This study introduces a novel sugar-glued tether-assisted technique inspired by a traditional Chinese snack-making process to enhance cardia visualization and patient comfort during MCG. METHODS: This pilot, open-label, single-center, randomized controlled, non-inferiority study was conducted at Binzhou Medical University Hospital. Seventy-eight patients were enrolled and divided into three groups: conventional MCG, suction cup tether-assisted MCG, and sugar-glued tether-assisted MCG. The primary outcomes included safety, comfort level, and gastric cardia visualization quality. Secondary outcomes assessed technique-associated performance and clinical factors. RESULTS: The sugar-glued tether-assisted MCG demonstrated comparable cardia visualization quality to the suction cup method, with significantly better results than conventional MCG. Comfort levels were significantly higher in the sugar-glued group compared to the suction cup group. The number of swallow attempts was significantly lower in the sugar-glued group, with no adverse events reported. Secondary outcomes showed no significant differences in MCG assembly time and ingestion-to-detachment period between the suction cup and sugar-glued groups. CONCLUSION: The sugar-glued tether-assisted MCG is a feasible and safe modification that enhances gastric cardia visualization while improving patient comfort. This technique provides a cost-effective alternative to the suction cup method, warranting further investigation in larger, multi-center studies.

Broad-Spectrum Engineered Multivalent Nanobodies Against SARS-CoV-1/2.

SARS-CoV-2 Omicron sublineages escape most preclinical/clinical neutralizing antibodies in development, suggesting that previously employed antibody screening strategies are not well suited to counteract the rapid mutation of SARS-CoV-2. Therefore, there is an urgent need to screen better broad-spectrum neutralizing antibody. In this study, a comprehensive approach to design broad-spectrum inhibitors against both SARS-CoV-1 and SARS-CoV-2 by leveraging the structural diversity of nanobodies is proposed. This includes the de novo design of a fully human nanobody library and the camel immunization-based nanobody library, both targeting conserved epitopes, as well as the development of multivalent nanobodies that bind nonoverlapping epitopes. The results show that trivale B11-E8-F3, three nanobodies joined tandemly in trivalent form, have the broadest spectrum and efficient neutralization activity, which spans from SARS-CoV-1 to SARS-CoV-2 variants. It is also demonstrated that B11-E8-F3 has a very prominent preventive and some therapeutic effect in animal models of three authentic viruses. Therefore, B11-E8-F3 has an outstanding advantage in preventing SARS-CoV-1/SARS-CoV-2 infections, especially in immunocompromised populations or elderly people with high-risk comorbidities.

Efficient Hydrodeoxygenation of Lignin-derived Phenolic Compounds over Ru-based Catalyst with Biochar and Al2O3 as Composite Support.

Hydrodeoxygenation (HDO) is a common strategy for upgrading lignin-derived phenolic compounds into high-quality liquid fuels, and the support rational design of HDO catalysts is critical to achieve a good reaction performance. This work proposed a novel Ru-based catalyst with biochar and Al2O3 as composite support. The addition of biochar can enlarge the porous structure, and the addition of Al2O3 can enhance the acid property of the support. By regulating the content of biochar and Al2O3 components, Ru/CA-2 catalyst achieved the best HDO performance of lignin-derived phenolic compounds, with the optimal component balance of 50%C and 50%Al2O3. This catalyst possesses the high Ru metal dispersion (1.38 nm particle size) to activate the hydrogen source, the moderate acid property to suppress carbon deposition and the abundant oxygen vacancy to promote substrate adsorption at the same time. 99.9% conversion of guaiacol is obtained at 230 °C, with 99.9% selectivity towards cyclohexane. Ru/CA-2 catalyst also has a good recyclability, with no obvious activity loss after five runs. Furthermore, in the application of catalytic lignin-oil HDO, the content of hydrocarbons increase from 10.69% to 95.71%, showing great potential on the industrial usage.

Impact of prior SARS-CoV-2 infection on postoperative recovery in patients with hepatocellular carcinoma resection.

BACKGROUND: The impact of prior SARS-CoV-2 infection on postoperative recovery of patients who underwent liver resection for hepatocellular carcinoma (HCC) remains uncertain given the lack of sufficient evidence. AIM: To investigate the impact of prior SARS-CoV-2 infection on postoperative recovery of patients who underwent liver resection for hepatocellular carcinoma (HCC). METHODS: Patients who were pathologically diagnosed with HCC and underwent elective partial hepatectomy in Guangdong Provincial People's Hospital between January 2022 and April 2023 were enrolled in this retrospective cohort study. The patients were divided into two groups based on their history of SARS-CoV-2 infection. Rehabilitation parameters, including postoperative liver function, incidence of complications, and hospitalization expenses, were compared between the two groups. Propensity score matching (PSM) was performed to reduce confounding bias. RESULTS: We included 172 patients (58 with and 114 without prior SARS-CoV-2 infection) who underwent liver resection for HCC. No significant differences in the rehabilitation parameters were observed between the two groups. After PSM, 58 patients were selected from each group to form the new comparative groups. Similar results were obtained within the population after PSM. CONCLUSION: Prior SARS-CoV-2 infection does not appear to affect postoperative rehabilitation, including liver function, postoperative complications, or hospitalization expenses among patients with HCC after elective partial hepatectomy.

CD133+/ABCC5+ cervical cancer cells exhibit cancer stem cell properties.

Objective: This study explores the correlation between Forkhead box M1 (FOXM1) and ATP-binding cassette subfamily C member 5 (ABCC5) in relation to paclitaxel resistance in cervical cancer. It aims to identify potential cervical cancer stem cell markers, offering fresh perspectives for developing therapeutic strategies to overcome paclitaxel chemoresistance in cervical cancer. Methods: Paclitaxel-resistant Hela cells (Hela/Taxol) were developed by intermittently exposing Hela cells to progressively increasing concentrations of paclitaxel. We assessed the biological properties of both Hela and Hela/Taxol cells using various assays: cell proliferation, clonogenic, cell cycle, apoptosis, scratch, and transwell. To determine which markers better represent tumor stem cells, we analyzed various known and potential stem cell markers in combination. Flow cytometry was employed to measure the proportion of positive markers in both parental and drug-resistant cell lines. Following statistical analysis to establish relative stability, CD133+ABCC5+ cells were sorted for further examination. Subsequent tests included sphere-forming assays and Western blot analysis to detect the presence of the stem cell-specific protein Sox2, aiding in the identification of viable cervical cancer stem cell markers. Results: The Hela/Taxol cell line exhibited significantly enhanced proliferation, migration, and invasion capabilities compared to the Hela cell line, alongside a marked reduction in apoptosis rates (P < 0.01). Notably, proportions of CD44+, CD24+CD44+, ABCC5+, CD24+CD44+ABCC5+, CD44+ABCC5+, CD24+CD44+FOXM1+, CD44+FOXM1+, CD133+ABCC5+, and CD133+FOXM1+ were significantly higher (P < 0.05). Furthermore, the size and number of spheres formed byCD133+ABCC5+ cells were greater in the sorted Hela/Taxol line (P < 0.01), with increased expression of the stem cell marker Sox2 (P < 0.001). Conclusion: The Hela/Taxol cells demonstrate increased tumoral stemness, suggesting that CD133+ABCC5+ may serve as a novel marker for cervical cancer stem cells.

LINC01197 inhibits influenza A virus replication by serving as a PABPC1 decoy.

Influenza A viruses (IAVs) significantly impact animal and human health due to their zoonotic potential. A growing body of evidence indicates that the host's long noncoding RNAs (lncRNAs) play crucial roles in regulating host-virus interactions during IAV infection. However, numerous lncRNAs associated with IAV infection have not been well characterised. Here, in this study, we identify the LINC01197 as an antiviral host factor. LINC01197 was significantly upregulated after IAV infection, which is controlled by the NF-κB pathway. Functional analysis revealed that overexpression of LINC01197 inhibited IAV replication and virus production, while knockdown of LINC01197 facilitated IAV replication. Mechanistically, LINC01197 directly interacts with poly(A) binding protein cytoplasmic 1 (PABPC1), which in turn sequesters and restricts its functions. This work shows that LINC01197 acts as a protein decoy, suppressing IAV replication and playing a key role in controlling IAV replication.

Efficacy and safety of the S1PR modulator etrasimod in the treatment of moderately to severely active ulcerative colitis during the induction phase: a systematic review and meta-analysis of randomized controlled trials.

Background: The study aims to assess the efficacy and safety of the recently approved S1PR modulator etrasimod in adults with ulcerative colitis during the induction phase through meta-analysis. Methods: A systemic search was performed for randomized controlled trials evaluating the efficacy and safety of the S1PR modulator etrasimod using electronic databases PubMed, Embase, the Cochrane Library, Clinical Trials, and the International Clinical Trials Registry Platform. Three studies with 943 patients met the inclusion criteria and were included in this analysis. The study's primary endpoint was the proportion of patients who achieved clinical remission at week 12. Key secondary endpoints included the proportion of patients with clinical response, endoscopic improvement, and histologic remission. The incidence of adverse effects (AEs), serious AEs (SAEs), and AE-related treatment discontinuation were statistically analyzed to determine the safety of etrasimod. Results: This study revealed that etrasimod is superior to placebo at the primary endpoint clinical remission (OR = 3.09, 95% CI: 2.04-4.69), as well as at the secondary endpoints clinical response (OR = 2.56, 95% CI: 1.91-3.43), endoscopic improvement (OR = 2.15, 95% CI: 1.51-3.05), and histologic remission (OR = 3.39, 95% CI: 2.03-5.68). The proportion of patients with TEAE (OR = 1.34, 95% CI: 1.01-1.78) and SAE (OR = 0.77, 95% CI: 0.41-1.43) was similar between the etrasimod and placebo groups. Patients receiving etrasimod had slightly higher odds of experiencing headache (OR = 2.07, 95% CI: 1.01-4.23), and nausea (OR = 1.84, 95% CI: 0.72-4.72). The incidences of upper respiratory tract infection (OR = 0.79, 95% CI: 0.27-2.32), nasopharyngitis (OR = 0.40, 95% CI: 0.15-1.07), and urinary tract infection (OR = 1.82, 95% CI: 0.59-5.60) were generally lower in the etrasimod groups and no treatment-related serious infections were reported. Conclusion: This study demonstrates that etrasimod is effective in treating moderately to severely active ulcerative colitis with a favorable benefit-risk profile at week 12. Etrasimod shows promise as a potential first-line oral therapy for individuals suffering from this disease. Additional RCTs with larger sample sizes and longer observation periods are needed to confirm the sustained efficacy of etrasimod beyond the initial phase.

Efficacy of hepatic arterial infusion chemotherapy and its combination strategies for advanced hepatocellular carcinoma: A network meta-analysis.

BACKGROUND: With the rapid progress of systematic therapy for hepatocellular carcinoma (HCC), therapeutic strategies combining hepatic arterial infusion chemotherapy (HAIC) with systematic therapy arised increasing concentrations. However, there have been no systematic review comparing HAIC and its combination strategies in the first-line treatment for advanced HCC. AIM: To investigate the efficacy and safety of HAIC and its combination therapies for advanced HCC. METHODS: A network meta-analysis was performed by including 9 randomized controlled trails and 35 cohort studies to carry out our study. The outcomes of interest comprised overall survival (OS), progression-free survival (PFS), tumor response and adverse events. Hazard ratios (HR) and odds ratios (OR) with a 95% confidence interval (CI) were calculated and agents were ranked based on their ranking probability. RESULTS: HAIC outperformed Sorafenib (HR = 0.55, 95%CI: 0.42-0.72; HR = 0.51, 95%CI: 0.33-0.78; OR = 2.86, 95%CI: 1.37-5.98; OR = 5.45, 95%CI: 3.57-8.30; OR = 7.15, 95%CI: 4.06-12.58; OR = 2.89, 95%CI: 1.99-4.19; OR = 0.48, 95%CI: 0.25-0.92, respectively) and transarterial chemoembolization (TACE) (HR = 0.50, 95%CI: 0.33-0.75; HR = 0.62, 95%CI: 0.39-0.98; OR = 3.08, 95%CI: 1.36-6.98; OR = 2.07, 95%CI: 1.54-2.80; OR = 3.16, 95%CI: 1.71-5.85; OR = 2.67, 95%CI: 1.59-4.50; OR = 0.16, 95%CI: 0.05-0.54, respectively) in terms of efficacy and safety. HAIC + lenvatinib + ablation, HAIC + ablation, HAIC + anti- programmed cell death 1 (PD-1), and HAIC + radiotherapy had the higher likelihood of providing better OS and PFS outcomes compared to HAIC alone. HAIC + TACE + S-1, HAIC + lenvatinib, HAIC + PD-1, HAIC + TACE, and HAIC + sorafenib had the higher likelihood of providing better partial response and objective response rate outcomes compared to HAIC. HAIC + PD-1, HAIC + TACE + S-1 and HAIC + TACE had the higher likelihood of providing better complete response and disease control rate outcomes compared to HAIC alone. CONCLUSION: HAIC proved more effective and safer than sorafenib and TACE. Furthermore, combined with other interventions, HAIC showed improved efficacy over HAIC monotherapy according to the treatment ranking analysis.

Volatilomics of Cabernet Sauvignon grapes and sensory perception of wines are affected by canopy side in vineyards with different row orientations.

This study aimed to clarify how microclimate diversity altered volatilomics in Cabernet Sauvignon grapes and wines. Four row-oriented vineyards were selected, and metabolites of grapes and wines were determined from separate canopy sides. Results showed that shaded sides received 59% of the solar radiation and experienced 55% of the high-temperature days compared to the exposed sides on average. Grape primary metabolites were slightly affected by the canopy side. Herbaceous aromas were consistently more abundant in grapes and wines from shaded clusters. Heat-stressed canopy sides accelerated terpenoid loss and increased norisoprenoid levels in grapes, while ß-damascenone in north-side wines was 13%-32% higher than that in south-side wines of the east-west vineyard. The northeast-southwest vineyard showed the most notable variation in taste and aroma sensory scores, with four parameters significantly different. There were 32 aroma series identified in wines, and banana, pineapple, and strawberry odors were highly correlated with aroma sensory score.

Poly-L-lactic acid fillers for nasal alar retraction: safety and effectiveness in 13 cases.

OBJECTIVE: To assess the effectiveness and safety of poly-L-lactic acid (PLLA) fillers in treating nasal alar retraction. We conducted a series of case reports on 13 patients treated for nasal alar retraction at the Chengdu Ningyue FRESKIN Medicine Cosmology Clinic from September 2022 to July 2023. Patients ranged from 23 to 49 years, comprising 12 females and 1 male. Of these, 5 had no prior medical history, 7 had previously undergone rhinoplasty, and 1 had a history of nasal trauma. Treatment outcomes and adverse reactions were monitored following PLLA filler injections. The mean pre-treatment severity score was 1.62±0.65, improving to 0.54±0.66 post-treatment (t=4.19, df=23, P<0.001). All participants reported satisfaction with their results without adverse effects. PLLA facial fillers are a safe and effective treatment for nasal alar retraction, presenting no embolism risk. This treatment merits consideration for broader clinical application.

Volatomic differences among Vitis amurensis cultivars and its hybrids with V. vinifera revealed the effects of genotype, region, and vintage on grape aroma.

Vitis amurensis grape, an East Asian Vitis species, has excellent cold and disease resistance and exhibits high winemaking potential. In this study, the aroma compounds in grapes from five V. amurensis cultivars ('Beiguohong', 'Beiguolan', 'Shuangfeng', 'Shuanghong', 'Shuangyou') and three interspecific hybrids ('Beibinghong', 'Xuelanhong', 'Zuoyouhong') from two regions (Zuojia and Ji'an, Jilin, China) were identified via HS-SPME-GC/MS. The results showed that V. amurensis grapes had a greater concentration of aroma compounds than the interspecific hybrid berries. 'Beibinghong' was relatively rich in terpenes, although their concentrations were all lower than the threshold. 'Shuangfeng' contained more concentrations of free C6/C9 compounds, alcohols, aromatics and aldehydes/ketones than the other cultivars. The aroma characteristics of 'Beiguolan' and 'Shuanghong' were relatively similar. The grapes from the lower temperature and more fertile soil of Zuojia contained more C6/C9 compounds, norisoprenoids and alcohols, while aromatics were more abundant in the grapes from Ji'an, which was warmer than the Zuojia region. Herbaceous, floral, fruity and sweet were the main aroma series of V. amurensis grapes. Our study could provide a reference for the development and utilization of V. amurensis grapes and lay a foundation for the development of wild grape cultivars and the production of wines with characteristic styles.

The first structure of human Golm1 coiled coil domain reveals an unexpected tetramer and highlights its structural diversity.

Golgi membrane protein 1 (Golm1), a transmembrane protein with diverse subcellular localizations, has garnered significant attention in recent years due to its strong association with the development and progression of liver diseases and numerous cancers. Interestingly, although Golm1 is a membrane protein, the C-terminal of Golm1, which contains a coiled coil domain and a flexible acid region, can also be detected in the plasma of patients with various liver diseases. Notably, the coiled coil domain of serum Golm1 is postulated to play a pivotal role in physiological and pathological functions. However, little is currently known about the structure of this coiled coil domain and the full-length protein, which may limit our understanding of Golm1. Therefore, this study aims to address this gap in knowledge and reports the first crystal structure of the coiled coil domain of Golm1 at a resolution of 2.28 Å. Meanwhile, we have also confirmed that the Golm1 coiled coil domain in solution can form tetramer. Our results reveal that Golm1 can form a novel tetrameric structure that differs from the previous reported dimeric structure Golm1 could assemble, which may provide novel insights into the diversity of physiological functions and pathological roles.

GNA13 suppresses proliferation of ER+ breast cancer cells via ERα dependent upregulation of the MYC oncogene.

GNA13 (Gα13) is one of two alpha subunit members of the G12/13 family of heterotrimeric G-proteins which mediate signaling downstream of GPCRs. It is known to be essential for embryonic development and vasculogenesis and has been increasingly shown to be involved in mediating several steps of cancer progression. Recent studies found that Gα13 can function as an oncogene and contributes to progression and metastasis of multiple tumor types, including ovarian, head and neck and prostate cancers. In most cases, Gα12 and Gα13, as closely related α-subunits in the subfamily, have similar cellular roles. However, in recent years their differences in signaling and function have started to emerge. We previously identified that Gα13 drives invasion of Triple Negative Breast Cancer (TNBC) cells in vitro. As a highly heterogenous disease with various well-defined molecular subtypes (ER+ /Her2-, ER+ /Her2+, Her2+, TNBC) and subtype associated outcomes, the function(s) of Gα13 beyond TNBC should be explored. Here, we report the finding that low expression of GNA13 is predictive of poorer survival in breast cancer, which challenges the conventional idea of Gα12/13 being universal oncogenes in solid tumors. Consistently, we found that Gα13 suppresses the proliferation in multiple ER+ breast cancer cell lines (MCF-7, ZR-75-1 and T47D). Loss of GNA13 expression drives cell proliferation, soft-agar colony formation and in vivo tumor formation in an orthotopic xenograft model. To evaluate the mechanism of Gα13 action, we performed RNA-sequencing analysis on these cell lines and found that loss of GNA13 results in the upregulation of MYC signaling pathways in ER+ breast cancer cells. Simultaneous silencing of MYC reversed the proliferative effect from the loss of GNA13, validating the role of MYC in Gα13 regulation of proliferation. Further, we found Gα13 regulates the expression of MYC, at both the transcript and protein level in an ERα dependent manner. Taken together, our study provides the first evidence for a tumor suppressive role for Gα13 in breast cancer cells and demonstrates for the first time the direct involvement of Gα13 in ER-dependent regulation of MYC signaling. With a few exceptions, elevated Gα13 levels are generally considered to be oncogenic, similar to Gα12. This study demonstrates an unexpected tumor suppressive role for Gα13 in ER+ breast cancer via regulation of MYC, suggesting that Gα13 can have subtype-dependent tumor suppressive roles in breast cancer.

The pseudogene GBP1P1 suppresses influenza A virus replication by acting as a protein decoy for DHX9.

Recently, substantial evidence has demonstrated that pseudogene-derived long noncoding RNAs (lncRNAs) as regulatory RNAs have been implicated in basic physiological processes and disease development through multiple modes of functional interaction with DNA, RNA, and proteins. Here, we report an important role for GBP1P1, the pseudogene of guanylate-binding protein 1, in regulating influenza A virus (IAV) replication in A549 cells. GBP1P1 was dramatically upregulated after IAV infection, which is controlled by JAK/STAT signaling. Functionally, ectopic expression of GBP1P1 in A549 cells resulted in significant suppression of IAV replication. Conversely, silencing GBP1P1 facilitated IAV replication and virus production, suggesting that GBP1P1 is one of the interferon-inducible antiviral effectors. Mechanistically, GBP1P1 is localized in the cytoplasm and functions as a sponge to trap DHX9 (DExH-box helicase 9), which subsequently restricts IAV replication. Together, these studies demonstrate that GBP1P1 plays an important role in antagonizing IAV replication.IMPORTANCELong noncoding RNAs (lncRNAs) are extensively expressed in mammalian cells and play a crucial role as regulators in various biological processes. A growing body of evidence suggests that host-encoded lncRNAs are important regulators involved in host-virus interactions. Here, we define a novel function of GBP1P1 as a decoy to compete with viral mRNAs for DHX9 binding. We demonstrate that GBP1P1 induction by IAV is mediated by JAK/STAT activation. In addition, GBP1P1 has the ability to inhibit IAV replication. Importantly, we reveal that GBP1P1 acts as a decoy to bind and titrate DHX9 away from viral mRNAs, thereby attenuating virus production. This study provides new insight into the role of a previously uncharacterized GBP1P1, a pseudogene-derived lncRNA, in the host antiviral process and a further understanding of the complex GBP network.

Single-cell transcriptomics reveals CD8+ T cell structure and developmental trajectories in idiopathic pulmonary fibrosis.

Immune cells in the human lung are associated with idiopathic pulmonary fibrosis. However, the contribution of different immune cell subpopulations to the pathogenesis of pulmonary fibrosis remains unclear. We used single-cell RNA sequencing data to investigate the transcriptional profiles of immune cells in the lungs of 5 IPF patients and 3 subjects with non-fibrotic lungs. In an identifiable population of immune cells, we found increased percentage of CD8+ T cells in the T cell subpopulation in IPF. Monocle analyzed the dynamic immune status and cell transformation of CD8+ T cells, as well as the cytotoxicity and exhausted status of CD8+ T cell subpopulations at different stages. Among CD8+ T cells, we found differences in metabolic pathways in IPF and Ctrl, including lipid, amino acid and carbohydrate metabolic. By analyzing the metabolites of CD8+ T cells, we found that different populations of CD8+ T cells in IPF have unique metabolic characteristics, but they also have multiple identical up-regulated or down-regulated metabolites. In IPF, signaling pathways associated with fibrosis were enriched in CD8+ T cells, suggesting that CD8+ T cells may have an important contribution to fibrosis. Finally, we analyzed the interactions between CD8+ T cells and other cells. Together, these studies highlight key features of CD8+ T cells in the pathogenesis of IPF and help to develop effective therapeutic targets.

Needs and Constraints for Cardiac Rehabilitation Among Patients with Coronary Heart Disease Within a Community-Based Setting: A Study Based on Focus Group Interviews.

Objective: This study aimed to explore the needs and constraints to cardiac rehabilitation (CR) among patients diagnosed with coronary heart disease (CHD) in a community-based setting, and thereby facilitating the implementation of effective CR programs for this population. Methods: Focus group interviews were used as the primary research methodology. A total of 11 community-dwelling individuals diagnosed with CHD were selected from a community hospital to participate in in-depth interviews, aiming to discern and analyze their requirements and constraints experienced concerning medical resources and healthcare agency. The textual data underwent examination using Colaizzi's method of descriptive data analysis. Results: Deficits existed in the perceptions of patients with CHD within a community-based setting about their condition and CR, and in the social support for this disease. Patients expressed expectations for professional guidance during CR, gained an understanding about the beneficial effects of emotional stability on cognitive function. Patients expressed their thoughts and feelings regarding the diversity of physical exercise options. Two main themes and seven sub-themes were identified: (a) "Insufficient CR resources for patients": Lack of awareness about CHD; inadequate knowledge about secondary prevention/CR; insufficient support from family and friends. (b) "Patient CR initiative": Patient self-adjustment; expectation of professional rehabilitation guidance; stable emotions improving cognition; diverse attitudes and awareness of exercise. Conclusion: For more effective CR, community-based medical teams should provide more comprehensive and individualized rehabilitation programs. They should focus on individual variations and preferences of patients, as well as enhance the autonomy of patients and improve their self-care ability through effective empowerment measures.

Metabolomics of Vitis davidii Foëx. grapes from southern China: Flavonoids and volatiles reveal the flavor profiles of five spine grape varieties.

The spine grapes (Vitis davidii Foëx.) are wild grape species that grow in southern China, and can be used for table grapes, juicing and winemaking. To systematically investigate the flavor profiles of spine grapes, flavonoids and volatile compounds were detected in five spine grape varieties (Seputao, Ziqiu, Miputao, Tianputao and Baiputao) using HPLC-QqQ-MS/MS and GC-MS. The content of flavonoids highly depended on the variety, such as the total concentrations of anthocyanins (91.43-328.85 mg/kg FW) and flavonols (33.90 to 83.16 mg/kg FW). The volatile compounds with higher odor active value were selected to describe the aroma of spine grapes. Hexanal, (E)-2-hexenal and (E, Z)-2,6-nonadienal contributed to the higher herbaceous flavor to Baiputao and Ziqiu. ß-Damascenone and (E)-2-nonenal gave Baiputao a flavor with more floral, fruity and earthy. Their characteristic flavor compounds were subsequently revealed using multivariate statistical analysis. The results helped producers to further develop and utilize the spine grapes.

Genomic analysis of Cobetia sp. D5 reveals its role in marine sulfur cycling.

Dimethylsulfoniopropionate (DMSP) is one of the most abundant sulfur-containing organic compounds on the earth, which is an important carbon and sulfur source and plays an important role in the global sulfur cycle. Marine microorganisms are an important group involved in DMSP metabolism. The strain Cobetia sp. D5 was isolated from seawater samples in the Yellow Sea area of Qingdao during an algal bloom. There is still limited knowledge on the capacity of DMSP utilization of Cobetia bacteria. The study reports the whole genome sequence of Cobetia sp. D5 to understand its DMSP metabolism pathway. The genome of Cobetia sp. D5 consists of a circular chromosome with a length of 4,233,985 bp and the GC content is 62.56%. Genomic analysis showed that Cobetia sp. D5 contains a set of genes to transport and metabolize DMSP, which can cleave DMSP to produce dimethyl sulphide (DMS) and 3-Hydroxypropionyl-Coenzyme A (3-HP-CoA). DMS diffuses into the environment to enter the global sulfur cycle, whereas 3-HP-CoA is catabolized to acetyl CoA to enter central carbon metabolism. Thus, this study provides genetic insights into the DMSP metabolic processes of Cobetia sp. D5 during a marine algal bloom, and contributes to the understanding of the important role played by marine bacteria in the global sulfur cycle.
