Delivery of Stem Cells and BMP-2 With Functionalized Self-Assembling Peptide Enhances Regeneration of Infarcted Myocardium.

Stem cell transplantation is a promising therapeutic strategy for myocardial infarction (MI). However, engraftment, survival and differentiation of the transplanted stem cells in ischemic and inflammatory microenvironment are poor. We designed a novel self-assembly peptide (SAP) by modifying the peptide RADA16 with cell-adhesive motif and BMP-2 (bone morphogenetic protein-2)-binding motif. Effects of the functionalized SAP on adhesion, survival and differentiation of c-kit+ MSCs (mesenchymal stem cells) were examined. Myocardial regeneration, neovascularization and cardiac function were assessed after transplantation of the SAP loading c-kit+ MSCs and BMP-2 in rat MI models. The SAP could spontaneously assemble into well-ordered nanofibrous scaffolds. The cells adhered to the SAP scaffolds and spread well. The SAP protected the cells in the condition of hypoxia and serum deprivation. Following degradation of the SAP, BMP-2 was released sustainedly and induced c-kit+ MSCs to differentiate into cardiomyocytes. At four weeks after transplantation of the SAP loading c-kit+ MSCs and BMP-2, myocardial regeneration and angiogenesis were enhanced, and cardiac function was improved significantly. The cardiomyocytes differentiated from the engrafted c-kit+ MSCs were increased markedly. The differentiated cells connected with recipient cardiomyocytes to form gap junctions. Collagen volume was decreased dramatically. These results suggest that the functionalized SAP promotes engraftment, survival and differentiation of stem cells effectively. Local sustained release of BMP-2 with SAP is a viable strategy to enhance differentiation of the engrafted stem cells and repair of the infarcted myocardium.

Efficacy of physiological seawater nasal irrigation for the treatment of children with SARS-CoV-2 Omicron BA.2 variant infection: a randomized controlled trial.

BACKGROUND: Saline nasal irrigation is an effective therapy for relieving common cold symptoms. This study aimed to investigate and explore the efficacy of physiological seawater nasal irrigation (PSNI) on children with mild and asymptomatic infection with Omicron. METHODS: This randomized controlled trial was conducted in Shanghai, China, and 403 children with mild and asymptomatic infection with Omicron were included. These children were allocated into the PSNI group and the control group. The primary outcome was the duration of viral shedding (DVS), and the secondary outcome was the change in clinical symptoms. RESULTS: The median age of all participants was 5.59 (6.26) years old. The DVS was significantly shorter in the PSNI group [2.40 (1.13)] than in the control group [3.09 (2.14)] (P = 0.014). The multivariable Cox regression model also showed that patients in the PSNI group had an increased probability of shorter DVS compared with patients in the control group [hazard ratio (HR), 1.27; 95% confidence interval (CI), 1.04-1.55; P = 0.017]. Subgroup analysis suggested that the DVS of patients without full vaccination was significantly reduced in the PSNI group. The proportions of runny nose and stuffy nose were apparently reduced in the first three days in the PSNI group or the control group, but there was no evidence showing that PSNI contributes to the benefit compared with the control group. CONCLUSION: PSNI can reduce the DVS of patients with mild and asymptomatic infection with SARS-CoV-2 Omicron BA.2 variant.

Climate and geochemistry at different altitudes influence soil fungal community aggregation patterns in alpine grasslands.

Fungi represent key ecosystem factors that affect plant growth and development and improve soil structure and fertility. Due to changes in environmental conditions, fungi show strong spatial heterogeneity along altitudinal gradients. Current knowledge of the driving mechanisms and effects of soil fungal community construction at high altitudes is very limited on a regional scale. We collected soil samples from alpine grasslands at six altitudinal gradients (2813-5228 m) in the high-altitude area of the Qinghai-Tibet Plateau. The horizontal distance of the sampling zone spanned 1500 km. Distribution patterns, key influencing factors for soil fungal diversity, and dominant mechanisms of ecological processes in the alpine grasslands were analyzed. We found that the diversity of the soil fungal communities was significantly different at different altitudes; with increasing altitude, the number of fungal species increased. Mucoromycota was better adapted to alpine grassland ecosystems at altitudes of above 4000 m. Dispersal limitation was the main ecological control process among stochastic processes. With the increase of altitude, the dominant role of dispersal limitation gradually decreased, and the proportion of other random processes such as ecological drift gradually increased. In this study, soil geochemical factors (soil organic carbon, SOC; total phosphorus, TP) mainly influenced the composition of the fungal community in the low altitude region, while climatic factors (mean annual temperature, MAT) were the key factors and main driving forces for the composition of the soil fungal community in the alpine meadow in the high altitude region. This study supplements the information on the biogeographic distribution patterns and environmental drivers of fungal communities along altitudinal gradients at high altitudes on a regional scale. Our results highlight the effects of temperature change on fungal community composition in high altitude regions of alpine grasslands. Subsurface fungal communities should be considered when predicting the function of alpine grassland ecosystems under future climate change.

Alteration of neural activity and neuroinflammatory factors in the insular cortex of mice with corneal neuropathic pain.

Dry eye disease (DED) affects nearly 55% of people worldwide; several studies have proposed that central sensitization and neuroinflammation may contribute to the developing corneal neuropathic pain of DED, while the underlying mechanisms of this contribution remain to be investigated. Excision of extra orbital lacrimal glands established the dry eye model. Corneal hypersensitivity was examined through chemical and mechanical stimulation, and open field test measured the anxiety levels. Restingstate fMRI is a method of functional magnetic resonance imaging (rs-fMRI) was performed for anatomical involvement of the brain regions. The amplitude of low-frequency fluctuation (ALFF) determined brain activity. Immunofluorescence testing and Quantitative real-time polymerase chain reaction were also performed to further validate the findings. Compared with the Sham group, ALFF signals in the supplemental somatosensory area, secondary auditory cortex, agranular insular cortex, temporal association areas, and ectorhinal cortex brain areas were increased in the dry eye group. This change of ALFF in the insular cortex was linked with the increment in corneal hypersensitivity (p < 0.01), c-Fos (p < 0.001), brain-derived neurotrophic factor (p < 0.01), TNF-α, IL-6, and IL-1ß (p < 0.05). In contrast, IL-10 levels (p < 0.05) decreased in the dry eye group. DED-induced corneal hypersensitivity and upregulation of inflammatory cytokines could be blocked by insular cortex injection of Tyrosine Kinase receptor B agonist cyclotraxin-B (p < 0.01) without affecting anxiety levels. Our study reveals that the functional activity of the brain associated with corneal neuropathic pain and neuroinflammation in the insular cortex might contribute to dry eye-related corneal neuropathic pain.

Evaluation of guidelines for the diagnosis and treatment of achalasia.

Due to the unclear quality of the current guidelines, users may be confused about how to diagnose and treat achalasia. The objective of this work is to systematically evaluate the methodological quality of the current guidelines for diagnosing and treating achalasia and to determine the heterogeneity among recommendations. We systematically searched literature databases to retrieve relevant guidelines for the diagnosis and treatment of achalasia. The Appraisal of Guidelines for Research and Evaluation II tool was used to evaluate the quality of the included guidelines. Key recommendations in the guidelines were extracted, and the reasons for the heterogeneity of the key recommendations between different guidelines were further analyzed. Seven guidelines on the diagnosis and treatment of achalasia are included in this study. The overall score of three guidelines exceeded 60%. The average score in domain 5 was the lowest, at 41.8%. The average scores in domain 2, domain 3, and domain 6 were also low, at 45.4%, 57.1% and 56.9%, respectively. The main recommendations and quality of evidence for different guidelines vary greatly, mainly due to the different emphases among different guidelines, the lack of systematic retrieval, or the unfairness of evidence use in some guidelines. There are considerable differences in the methodological quality of diagnosis and treatment guidelines for achalasia. Additionally, the differences in the main recommendations and evidence support among guidelines are also obvious. Guideline developers should improve the above related factors to decrease the heterogeneity, and they should further formulate or update the guidelines for the diagnosis and treatment of achalasia.

Hem-o-lok clip migration to the common bile duct after laparoscopic common bile duct exploration: A case report.

BACKGROUND: Laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration (LCBDE) has been widely used for management of gallbladder and common bile duct (CBD) stones. Post-operative clip migration is a rare complication of laparoscopic biliary surgery, which can serve as a nidus for stone formation and cause recurrent cholangitis. CASE SUMMARY: A 59-year-old female was admitted to hospital because of fever and acute right upper abdominal pain. She has a history of LC and had a LCBDE surgery 2 mo ago. Physical examination revealed tenderness in the upper quadrant of right abdomen. Computed tomography scan demonstrated a high-density shadow at the distal CBD, which was considered as migrated clips. The speculation was confirmed by endoscopic retrograde cholangiopancreatography examination, and two displaced Hem-o-lok clips were removed with a stone basket. No fever or abdominal pain presented after the operation. In addition to the case report, literature regarding surgical clip migration after laparoscopic biliary surgery was reviewed and discussed. CONCLUSION: Incidence of postoperative clip migration may be reduced by using clips properly and correctly; however, new methods should be explored to occlude cystic duct and vessels. If a patient with a past history of LC or LCBDE presents with features of sepsis and recurrent upper quadrant pain, clip migration must be considered as one of the differential diagnosis.

Systematic appraisal of the guidelines for the diagnosis and treatment of Hirschsprung's disease.

BACKGROUND: Some guidelines for management of Hirschsprung's disease (HSCR, HD) have been developed, but their quality is vague. This study will systematically assess the quality of guidelines and analyze the key recommendations and the best evidence for guidelines. METHODS: Applicable guidelines were retrieved using a systematic search of databases. The Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool was used to assess the quality of the guidelines. Then, the recommendations and evidence for the included guidelines were extracted and compared. RESULTS: A total of nine guidelines were included in this study, and only one had an overall standardized score of more than 60%, indicating that it is worthy of recommendation. The problems identified included ambiguous and low-quality evidence; obvious distributional heterogeneity among the recommendations; a lack of in-depth discussion on the interpretation of staging, diagnostic methods, conservative treatment, and surgical staging of disease. CONCLUSION: The quality of guidelines varies widely, and there is a lack of high-quality professional opinions and supporting evidence for the main recommendations. At present, only comprehensive guidelines can be considered high-quality and there is still room for improvement.

The Relationship of the Test for Respiratory and Asthma Control in Kids Initial Score on the Prognosis of Pre-school Children With Asthma: A Prospective Cohort Study.

Objective: The test for respiratory and asthma control in kids (TRACK) is currently the only standard follow-up tool for children under 5 years of age with asthma. The purpose of this study was to investigate the relationship between the TRACK initial score (Ti) and their prognosis after 6 months of follow-up in pre-schoolers with asthma. Design: A prospective cohort study. Methods: The study included pre-schoolers diagnosed with asthma at the Shanghai Children's Medical Center between January 2019 and June 2020, and follow-up for 6 months. TRACK scores, frequency of wheezing and respiratory infections, number of Emergency Department (ED) visits and treatment regimen were collected. According to the TRACK initial score, the children were divided into "Ti < 60 group" and "Ti ≥ 60 group," and the two groups were compared in terms of TRACK score related indicators, clinical manifestations and treatment. Results: There are 102 pre-schoolers included in the analysis [78 boys (76.5%) and 24 girls (23.5%); mean (SD) age, 28.05 (11.63) months]. After 6 months of follow-up, the TRACK score was improved in both groups, and the "Ti ≥ 60 group" had a higher score, lower rate of uncontrolled asthma and fewer reassessments were required. There was no difference in the number of wheezing attacks between the two groups in terms of clinical presentation, but the "Ti < 60 group" had more respiratory infections and ED visits. Regarding the use of ICSs, in the "Ti < 60 groups," the dose of ICSs was higher and reduced slowly, and the dose difference between the two groups began to appear after 5 months of follow-up. Conclusion: TRACK is essential for pre-schoolers with asthma at the time they are diagnosed. In addition, if the TRACK initial score is < 60, the probability of poor prognosis is higher.

Rapamycin-Preactivated Autophagy Enhances Survival and Differentiation of Mesenchymal Stem Cells After Transplantation into Infarcted Myocardium.

Stem cell transplantation has been limited by poor survival of the engrafted cells in hostile microenvironment of the infarcted myocardium. This study investigated cytoprotective effect of rapamycin-preactivated autophagy on survival of the transplanted mesemchymal stem cells (MSCs). MSCs isolated from rat bone marrow were treated with 50 nmol/L rapamycin for 2 h, and then the cytoprotective effect of rapamycin was examined. After intramyocardial transplantation in rat ischemia/reperfusion models, the survival and differentiation of the rapamycin-pretreated calls were accessed. After treatment with rapamycin, autophagic activities and lysososme production of the cells were increased significantly. In the condition of short-term or long-term hypoxia and serum deprivation, the apoptotic cells in rapamycin-pretreated cells were less, and secretion of HGF, IGF-1, SCF, SDF-1 and VEGF was increased. After transplantation of rapamycin-pretreated cells, repair of the infarcted myocardium and restoration of cardial function were enhanced dramatically. Expression of HGF, IGF-1, SCF, SDF-1, VEGF, HIF-1α and IL-10 in the myocardium was upregulated, while expression of IL-1ß and TNF-α was downregulated. Tracing of GFP and Sry gene showed that the survival of rapamycin-pretreated cells was increased. Cardiomyogenesis and angiogenesis in the infarcted myocardium were strengthened. Some rapamycin-pretreated cells differentiated into cardiomyocytes or endothelial cells. These results demonstrate that moderate preactivation of autophagy with rapamycin enhances the survival and differentiation of the transplanted MSCs. Rapamycin-primed MSCs can promote repair of the infarcted myocardium and improvement of cardiac function effectively.

Integrated microRNA and gene expression profiling reveals the crucial miRNAs in curcumin anti-lung cancer cell invasion.

BACKGROUND: Curcumin (diferuloylmethane) has chemopreventive and therapeutic properties against many types of tumors, both in vitro and in vivo. Previous reports have shown that curcumin exhibits anti-invasive activities, but the mechanisms remain largely unclear. METHODS: In this study, both microRNA (miRNA) and messenger RNA (mRNA) expression profiles were used to characterize the anti-metastasis mechanisms of curcumin in human non-small cell lung cancer A549 cell line. RESULTS: Microarray analysis revealed that 36 miRNAs were differentially expressed between the curcumin-treated and control groups. miR-330-5p exhibited maximum upregulation, while miR-25-5p exhibited maximum downregulation in the curcumin treatment group. mRNA expression profiles and functional analysis indicated that 226 differentially expressed mRNAs belonged to different functional categories. Significant pathway analysis showed that mitogen-activated protein kinase, transforming growth factor-ß, and Wnt signaling pathways were significantly downregulated. At the same time, axon guidance, glioma, and ErbB tyrosine kinase receptor signaling pathways were significantly upregulated. We constructed a miRNA gene network that contributed to the curcumin inhibition of metastasis in lung cancer cells. let-7a-3p, miR-1262, miR-499a-5p, miR-1276, miR-331-5p, and miR-330-5p were identified as key microRNA regulators in the network. Finally, using miR-330-5p as an example, we confirmed the role of miR-330-5p in mediating the anti-migration effect of curcumin, suggesting the importance of miRNAs in the regulation of curcumin biological activity. CONCLUSION: Our findings provide new insights into the anti-metastasis mechanism of curcumin in lung cancer.

Preparation and evaluation of a sustained-release buckwheat noodle.

BACKGROUND: Different carbohydrates elicit various effects on the digestibility and the glucose release rate, so it is of interest to develop a sustained-release noodle based on the combination of different carbohydrates and reveal the sustained-release mechanism. RESULTS: The data obtained suggest that xanthan and konjac gum exhibited excellent and synergistic sustained-release properties, whereas cornstarch showed the lowest average digestion rate. The sustained release was particularly evident when the noodle consisted of the following components: 50 g of 25 g kg(-1) hydrophilic colloid mixture solution composed of a 1:1 mass ratio of xanthan:konjac gum and 100 g of reconstructed flour consisting of 200 g kg(-1) buckwheat flour, 400 g kg(-1) cornstarch, and 400 g kg(-1) plain flour. The morphological structure of noodles revealed that the composite hydrophilic colloids strengthened the interaction between the gluten network and starch granules. This buried starch within the three-dimensional structure thereby releasing glucose in a slow and sustained way. The most suitable model to describe glucose release from noodles was the Ritger-Peppas equation, which revealed that matrix erosion contributed to the release mechanism. CONCLUSION: These findings indicate that the controlled use of hydrophilic colloids and starches in manufacturing noodles could modulate the glucose sustained-release. © 2015 Society of Chemical Industry.

[Investigation of social support for inpatients with occupational diseases].

OBJECTIVE: To investigate and analyze the social support for inpatients with occupational diseases and to provide reference and basis for relevant medical and nursing interventions. METHODS: The social support rating scale (SSRS) was used to investigate the social support for 95 inpatients with occupational diseases. RESULTS: The total SSRS score of these patients was significantly lower than the national norm (32.5±9.31 vs 34.56±3.73, P < 0.05). The social support was mainly from the family, but medical staff and spiritual support were the main source and type of social support that are expected. CONCLUSION: Patients with occupational diseases have gained little social support, in both economic and spiritual aspects. In clinical practice, the patient's demand for knowledge of diseases and spiritual needs should be satisfied, and appropriate social support should be provided.

Characterization of rat very small embryonic-like stem cells and cardiac repair after cell transplantation for myocardial infarction.

Stem cell therapy is a promising therapeutic strategy for treating myocardial infarction (MI). However, it is necessary to identify ideal adult stem cells for transplantation and explore mechanisms of the transplanted cells in improving cardiac functions after MI. In this study, a population of embryonic-like stem cells (ELSCs) was isolated from rat bone marrow. The cells express pluripotent stem cell transcriptional factors and present high proliferative activity on mouse embryonic fibroblast feeder. ELSCs retain clonal expansion and may form embryoid-like bodies in soft agarose containing leukemia inhibitory factor and basic fibroblast growth factor. The cells of the embryoid-like bodies can differentiate into the cells from 3 germ layers. Under induction, the cells can differentiate into cardiomyocytes and endothelial cells. In MI models of female rats, the transplantation of preinduced ELSCs of male rats reduce scar area and improve cardiac function significantly. Comparing with marrow-derived mesenchymal stem cells and ELSCs without induction, effects of the preinduced ELSCs on myocardial repair and improvement of cardiac function are greater. Survival of the transplanted cells in the peri-infarcted and infarcted regions was examined by fluorescence in situ hybridization. Y chromosome-positive cells may differentiate toward cardiomyocytes and express cTnT and Cx43. Cx43 expression was observed at conjunction of Y chromosome-positive cells and recipient cardiomyocytes. Some Y chromosome-positive cells express CD31 and incorporate into the microvessels in the infarcted tissue. These results suggest that a population of ELSCs resides in rat bone marrow and display similar biological characteristics of ESCs. ELSCs can differentiate into cardiomyocytes and endothelial cells and contribute to cardiomyogenesis and angiogenesis in vivo. Cardiac function after MI may be significantly improved with transplantation of the preinduced ELSCs. Therefore, ELSCs are novel seed cells for stem cell transplantation in regenerative medicine.

Transplantation of marrow-derived cardiac stem cells carried in fibrin improves cardiac function after myocardial infarction.

The high death rate of the transplanted stem cells in the infarcted heart and the low efficiency of differentiation toward cardiomyocytes influence the outcome of stem cell transplantation for treatment of myocardial infarction (MI). Fibrin glue (FG) has been extensively used as a cell implantation matrix to increase cell survival. However, mechanisms of the effects of FG for stem cell transplantation to improve cardiac function are unclear. We have isolated c-kit+/Sca-1+ marrow-derived cardiac stem cells (MCSCs) from rat bone marrow; the cells expressed weakly early cardiac transcription factor Nkx2.5, GATA-4, Mef2C, and Tbx5. Effects of FG on survival, proliferation, and migration of MCSCs were examined in vitro. Cytoprotective effects of FG were assessed by exposure of MCSCs to anoxia. Efficacy of MCSC transplantation in FG was evaluated in the female rat MI model. The MCSCs survived well and proliferated in FG, and they may migrate out from the edge of FG in the wound and nature state. Acridine orange/ethidium bromide staining and lactate dehydrogenase analysis showed that MCSCs in FG were more resistant to anoxia as compared with MCSCs alone. In a rat MI model, cardiac function was improved and scar area was obviously reduced in group of MCSCs in FG compared with group of MCSCs and FG alone, respectively. Y chromosome fluorescence in situ hybridization showed that there were more survived MCSCs in group of MCSCs in FG than those in group of MCSCs alone, and most Y chromosome positive cells expressed cardiac troponin T (cTnT) and connexin-43 (Cx-43). Cx-43 was located between Y chromosome positive cells and recipient cardiomyocytes. Microvessel density in the peri-infarct regions and infarct regions significantly increased in group of MCSCs in FG. These results suggest that FG provide a suitable microenvironment for survival and proliferation of MCSCs and protect cells from apoptosis and necrosis caused by anoxia. MCSCs could differentiate into cardiomyocytes after being transplanted in the border of the infarcted myocardium and form connections with native cardiomyocytes. FG is helpful for MCSC transplantation to repair myocardium and improve cardiac function through promoting the survival, migration, and cardiomyogenic differentiation of MCSCs and inducing angiogenesis.

Proteomic analysis of rice leaves shows the different regulations to osmotic stress and stress signals.

Following the idea of partial root-zone drying (PRD) in crop cultivation, the morphological and physiological responses to partial root osmotic stress (PROS) and whole root osmotic stress (WROS) were investigated in rice. WROS caused stress symptoms like leaf rolling and membrane leakage. PROS stimulated stress signals, but did not cause severe leaf damage. By proteomic analysis, a total of 58 proteins showed differential expression after one or both treatments, and functional classification of these proteins suggests that stress signals regulate photosynthesis, carbohydrate and energy metabolism. Two other proteins (anthranilate synthase and submergence-induced nickel-binding protein) were upregulated only in the PROS plants, indicating their important roles in stress resistance. Additionally, more enzymes were involved in stress defense, redox homeostasis, lignin and ethylene synthesis in WROS leaves, suggesting a more comprehensive regulatory mechanism induced by osmotic stress. This study provides new insights into the complex molecular networks within plant leaves involved in the adaptation to osmotic stress and stress signals.

Dissection of additive, epistatic effect and Q x E interaction of quantitative trait loci influencing stigma exsertion under water stress in rice.

Four flowering related traits, spikelet number per panicle (SNP), percentage of single exserted stigma (PSES), dual exserted stigma (PDES) and total exserted stigma (PES) of a RI population with 185 lines under water stress and non-stress conditions for 2 years, were investigated in a drought tolerance screening facility. ANOVA results showed high significance between years, lines, and water stress treatments, together with interactions among them in pairs. Highest phenotypic correlation was found between PSES and PES (r = 0.9752***), followed by PDES and PES (r = 0.7150***), and PSES and PDES (r = 0.5424***). Based on a linkage map of 203 SSR markers, six main effect QTLs were detected for SNP and three or four main effect QTLs were associated with PSES, PDES and PES under stress or non-stress conditions. There were one to nine pairs of epistatic QTLs influencing SNP and stigma exsertion. The contribution rates of additive and epistatic effects seemed to be in a low magnitude for most cases (0.76%-9.92%) while a few QTLs or QTL pairs explained more than 10% of total variance. Some main effect QTL and epistasis were commonly detected among PSES, PDES and PES, explaining the high positive correlation between them. Few QTLs were detected under both water stress and non-stress condition, implying that drought had severe impact on the genetic behaviors of both spikelet number and stigma exsertion.

Crystallization and preliminary X-ray crystallographic analysis of a non-specific lipid-transfer protein with antipathogenic activity from Phaseolus mungo.

A 9 kDa non-specific lipid-transfer protein (nsLTP) from mung bean (Phaseolus mungo) seeds, displaying antifungal activity, antibacterial activity and lipid-transfer activity, was crystallized at 297 K using ammonium sulfate as a precipitant by means of the hanging-drop vapour-diffusion method. Native X-ray diffraction data were collected to a resolution of 2.4 A. The crystals are rhombohedral, belonging to space group P2(1)2(1)2(1), with unit-cell parameters a = 38.671, b = 51.785, c = 55.925 A. Assuming the presence of one molecule in the crystallographic asymmetric unit results in a Matthews coefficient (V(M)) of approximately 3.0 A(3) Da(-1), corresponding to a solvent content of about 58%.

A non-specific lipid transfer protein with antifungal and antibacterial activities from the mung bean.

A non-specific lipid transfer peptide (nsLTP) with antimicrobial activity was isolated from the mung bean (Phaseolus mungo) seeds. The procedure entailed aqueous extraction, ion exchange chromatography on CM-Sephadex and high performance liquid chromatography (HPLC) on POROS-HS-20. The peptide exhibited a molecular mass of 9.03 kDa in mass spectrometry. It exerted antifungal action toward Fusarium solani, Fusarium oxysporum, Pythium aphanidermatum and Sclerotium rolfsii, and antibacterial action against Staphylococcus aureus but not against Salmonella typhimurium. The lipid binding of this peptide was very similar to that of a previously described lipid transfer protein extracted from wheat seeds and maize seeds, indicating that it possessed lipid transfer activity. The present findings add to the scarcity of the literature on leguminous nsLTPs.
