The process of wound healing necessitates a specific environment, thus prompting extensive research into the utilization of hydrogels for this purpose. While numerous hydrogel structures have been investigated, the discovery of a self-healing hydrogel possessing favorable biocompatibility, exceptional mechanical properties, and effective hemostatic and antibacterial performance remains uncommon. In this work, a polyvinyl alcohol (PVA) hybrid hydrogel was meticulously designed through a simple reaction, wherein CuxO anchored sepiolite was incorporated into the hydrogel. The results indicate that introduction of sepiolite greatly improves the toughness, self-healing and adhesion properties of the PVA hydrogels. CuxO nanoparticles endow the hydrogels with excellent antibacterial performance towards Staphylococcus aureus and Escherichia coli. The application of hybrid hydrogels for fast hemostasis and wound healing are verified in vitro and in vivo with rat experiments. This work thereby demonstrates an effective strategy for designing biodegradable hemostatic and wound healing materials.

Background: Several insectivorous bat species are found in New England, yet research on them is still scarce. Current research shows the ecological importance of bats due to their control of insect populations, but they are endangered by habitat loss and White Nose Syndrome, among other threats. Pine barrens are an uncommon ecosystem found in New England that supports other rare taxa and could be important for these bat species. Methods: With hand-held audio recorders, we surveyed for bats in Montague Plains Wildlife Management Area in Massachusetts and Concord Pine Barrens in New Hampshire in June 2022. Our study objectives were to (1) describe the most common bat species and (2) compare bat activity across different habitat types at two managed pine barrens in New England. In particular, we examined bat activity related to habitat type (scrub oak, mature pitch pine, treated pitch pine, hardwood forest), habitat structure (i.e., canopy closure), time since prescribed fire, and path width. We analyzed our data through generalized linear modeling and logistic regression. Results: Overall, we were able to measure the presence of five out of the nine total species found in the area, including the endangered Myotis lucifugus (little brown bat). We recorded 293 bat calls, with the majority of calls from big brown bats (71%). We found significant differences (p < 0.05) in bat activity in relation to time since prescribed fire and habitat structure. The index of bat activity was greatest in pitch pine and hardwood forests and lowest in scrub oak and treated pitch pine habitats. With preliminary data, we also found that silver-haired bat presence was influenced by habitat type, with more detections at survey points in hardwood forests. Discussion: These findings demonstrate the importance of pine barrens as an ecosystem that supports bats in New England. According to the activity of bats in our study, closed canopy and mature pitch pine habitats may be prioritized in conservation efforts at managed barrens for bat species. Further research is recommended to better understand the relationship between prescribed fires, which are common in managed barrens, and bat activity.

Urban grasslands provide numerous ecosystem services, and their maintenance should be based on naturally regenerating plant populations. However, the urban environment is challenging for preserving viable populations, mostly because of their high fragmentation and small size, which can lead to genetic drift. We examined red clover (Trifolium pratense) in a medium-size city in Central Europe to test the cityscape effect on within- and among-population genetic diversity. We used eight inter-simple sequence repeat markers to examine the genetic structure of 16 populations, each represented by eight individuals. The isolation by resistance was analysed using a least cost patch approach, focusing on gene flow via pollinators. We found great variation among T. pratense populations, with no discernible geographic pattern in genetic diversity. We linked the diversity to the long history of the city and high stochasticity of land use changes that occurred with city development. In particular, we did not find that the Odra River (ca. 100 m wide) was a strong barrier to gene transfer. However, notable isolation was present due to resistance and distance, indicating that the populations are threatened by genetic drift. Therefore, gene movement between populations should be increased by appropriate management of urban green areas. We also found that small urban grassland (UG) patches with small populations can still hold rare alleles which significantly contribute to the overall genetic variation of T. pratense in the city.

Developing smart hydrogels with excellent physicochemical properties and multi-sensing capabilities for various simulation of human skin's functions still remains a great challenge. Here, based on simple and convenient one-step covalent cross-linking method enhanced by dynamic RS-Ag interactions, a skin-inspired multifunctional conductive hydrogel with desirable physicochemical properties (including high stretchability, self-adhesion, self-healing, decomposition and removability) is developed for highly sensitive dual-sensing of temperature and strain. Benefiting from the synergistic action of multiple hydrogen bonds, RS-Ag bonds and S-S bonds, the gel exhibited a novel thermosensitive mechanism. The prepared hydrogels exhibited extremely high mechanical properties (maximum tensile strength of 0.35 MPa, elongation at break nearly 1800%, compressive stress over 4.43 MPa), excellent self-healing (96.82% (stress), 88.45% (temperature), 73.89% (mechanical property)), decomposition (the molecular weight after decomposition is below 700) and self-adhesion (enhanced contact with the material interface). In addition, this conductive hydrogel could also simultaneously achieve highly sensitive temperature-sensing (TCR: 10.89) and stress-sensing (GF: 1.469). As a proof-to-concept, the hydrogel displayed superior capability for simulation of human skin to perception of touch, pressure and ambient temperature simultaneously, indicating promising applications in the fields of wearable devices, personal health care, and human-machine interfaces.

Self-healing hydrogels have emerged as the most promising alternatives to conventional brittle hydrogels used in the biomedical field due to the features of long-term stability and durability. However, the incompatibility between the fast self-healing property and enough mechanical strength of hydrogels remains a challenge. Therefore, hydrogels that possess not only mechanical toughness but also autonomous self-healing capacity are sought after. This review presents a comprehensive summary of the latest self-healing mechanisms. Specifically, we review various systems based on dynamic bonds, ranging from dynamic covalent bonds to non-covalent bonds. Additionally, this review presents different characterization methods for self-healing hydrogels, and also highlights their potential applications in the biomedical field, such as tissue engineering, drug delivery, cell therapy, and wound dressing. Furthermore, this review aims to provide valuable guidance for constructing diverse self-healing hydrogels with tailored functions.

Dill (Anethum graveolens L.) is an aromatic herb widely used in the food industry, with several commercial cultivars available with different qualitative characteristics. Commercial cultivars are usually preferred over landraces due to their higher yield and also the lack of improved landraces than can be commercialized. In Greece, however, traditional dill landraces are cultivated by local communities. Many are conserved in the Greek Gene Bank and the aim here was to investigate and compare the morphological, genetic, and chemical biodiversity of twenty-two Greek landraces and nine modern/commercial cultivars. Multivariate analysis of the morphological descriptors, molecular markers, and essential oil and polyphenol composition revealed that the Greek landraces were clearly distinguished compared with modern cultivars at the level of phenological, molecular and chemical traits. Landraces were typically taller, with larger umbels, denser foliage, and larger leaves. Plant height, density of foliage, density of feathering as well as aroma characteristics were desirable traits observed for some landraces, such as T538/06 and GRC-1348/04, which were similar or superior to those of some commercial cultivars. Polymorphic loci for inter-simple sequence repeat (ISSR) and start codon targeted (SCoT) molecular markers were 76.47% and 72.41% for landraces, and 68.24% and 43.10% for the modern cultivars, respectively. Genetic divergence was shown, but not complete isolation, indicating that some gene flow may have occurred between landraces and cultivars. The major constituent in all dill leaf essential oils was α-phellandrene (54.42-70.25%). Landraces had a higher α-phellandrene and dill ether content than cultivars. Two dill landraces were rich in chlorogenic acid, the main polyphenolic compound determined. The study highlighted for the first-time Greek landraces with desirable characteristics regarding quality, yield, and harvest time suitable for breeding programs to develop new dill cultivars with superior features.

BACKGROUND: Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders. IBS is characterized by recurrent chronic abdominal pain and altered bowel habits in the absence of organic damage. Although there are reviews and guidelines for treating IBS, the complexity and diversity of IBS presentation make treatment difficult. Treatment of IBS focuses on relieving symptoms as mild signs and symptoms can often be controlled by managing stress and by making changes in diet and lifestyle. The use of nutraceutical compounds has been advocated as a possible alternative treatment in patients with IBS. COLONIR® (Omega Pharma Srl, Milan, Italy) may be an alternative or adjuvant treatment in patients with gastrointestinal symptoms. This study aimed to evaluate the effect of this new nutraceutical formulation in inducing symptoms remission and improve gastrointestinal habits. METHODS: An initial cohort of 1004 consecutive patients referred to 25 different Units of Internal Medicine a/o Gastroenterology in Italy to perform colonoscopy for intestinal symptoms was asked to participate. Patients were treated for 2 months with two doses of nutraceuticals/day during meals namely COLONIR®. Patients were assessed at baseline and after 2 months to evaluate the frequency and severity of gastrointestinal symptoms in the past seven days with a questionnaire based on ROMA IV criteria. RESULTS: After 2 months, 899 patients completed the follow-up. COLONIR® achieved a statistically significant reduction of severity of symptoms in the study population without any documented side effects. CONCLUSIONS: These promising results, here reported, need to be confirmed, valuating the efficacy of COLONIR® in relieving gastrointestinal symptoms in IBS patients in further studies.

Background: Vine decline disease caused by the fungus Monosporascus cannonballus, is a threat to melon production (Cucumis melo L.) worldwide. Nonetheless, little is known about the metabolites produced during the host pathogen interaction. Thus, the objective of this study was to measure quantities of amino acids produced over time during such an interaction. Methods: Two melon genotypes named TAM-Uvalde (susceptible) and USDA PI 124104 (resistant) were grown and inoculated with M. cannonballus. The metabolites previously stated were measured before inoculation (0 hours) and 24, 48 and 72 hours after inoculation, using high performance liquid chromatography analysis. Results: The production of some amino acids during the interaction of the resistant and susceptible melon genotypes with the fungus M. cannonballus was different regarding quantities over time. Interestingly, hydroxy proline was always up-regulated in higher quantities in response to pathogen infection in the genotype TAM-Uvalde. Also, the up-regulation in higher quantities of gamma-aminobutyric acid in the genotype TAM-Uvalde 48 and 72 hours after inoculation, suggests more penetration of the pathogen in its roots. Hence, taken together, hydroxy proline and gamma-aminobutyric acid levels could be used as markers of susceptibility to vine decline disease caused by M. cannonballus, which could be useful in developing resistant varieties.

BACKGROUND: Complementary and alternative medicine (CAM) is used by about 40-90% of all patients with cancer. CAM also includes phytotherapy, which is considered to be a biologically based therapy. Depending on the survey, the users of phytotherapy account for up to 80%. The intention of the users is to fight cancer or to alleviate its symptoms. OBJECTIVES: Frequently used phytotherapeutics with their level of evidence and possible pitfalls are presented in a narrative review. Special attention is given to the uro-oncological context. MATERIALS AND METHODS: Popular phytotherapeutics (mistletoe, pomegranate, aloe vera, sage, ginger, ginseng) as well as three uronephrological plants (juniper, horsetail, bearberry) are classified and evaluated according to existing guidelines and by using a selective literature search. RESULTS: A total of nine plants were considered. Currently, there is no sufficient evidence for the use of pomegranate or mistletoe for tumor therapy. Guideline recommendations for or against symptom-oriented use exist for ginger (nausea; may be used), ginseng (fatigue; may be used), aloe vera (radiation dermatitis, should not be recommend), and bearberry (recurrent cystitis, may be used). A small number of studies on other symptoms and medicinal plants could be found (e.g., ginger - xerostomia, aloe vera - constipation, sage - oral mucositis or sweating). CONCLUSIONS: An integration of phytotherapeutic drugs into uro-oncological treatments concept can be considered. The benefits and risks of complementary herbal medicines (e.g., potential interactions with tumor therapy) must always be carefully weighed.

Hydrogel smart windows are promising candidates for the automatic modulation of light transmittance through thermo-, humidity-, and electrochromic mechanisms. However, thermo- and humidity-triggered hydrogel smart windows are usually passively controlled and are not convenient for achieving active actuation; electrochromic windows require complex assembly and energy input. In addition, existing hydrogel smart windows are susceptible to physical damage, which may significantly shorten their working life. Herein, a salt-triggered polyampholyte hydrogel (PAH) is developed as a novel smart window with active and facile actuation as well as self-healing ability. The dynamic ionic bonds in PAH can reversibly disassociate and reform in alternate aqueous sodium chloride solution (NaCl(aq.)) and H2O, accounting for the reversible transparency-shifting and efficient modulation of light transmittance. PAH also enables patterning through precisely localized treatment with NaCl(aq.), which is useful for one-time information input/storage. Information encryption can be further realized by embedding PAH into an inherently transparent hydrogel or pasting it on an information carrier; the visibility of information is in line with the transparency-shifting of PAH. Moreover, the dynamic ionic bonds can endow the PAH-derived hydrogel smart window with self-healing and automatic damage-repairing abilities without sacrificing light modulation. Thus, salt-triggered PAH provides a new idea for designing actively actuating hydrogel smart windows with multifunctionality.

ETHNOPHARMACOLOGICAL RELEVANCE: Dandelion (Taraxacum officinale Weber ex F. H. Wigg.), as a garden weed grown globally, has long been consumed as a therapeutic herb. Its folkloric uses include treatments of digestive disorders (dyspepsia, anorexia, stomach disorders, gastritis and enteritis) and associate complex ailments involving uterine, liver and lung disorders. AIM OF THE STUDY: The present study aims to critically assess the current state of research and summarize the potential roles of dandelion and its constituents in gastrointestinal (GI) -protective actions. A focus is placed on the reported bioactive components, pharmacological activities and modes of action (including molecular mechanisms and interactions among bioactive substances) of dandelion products/preparations and derived active constituents related to GI protection. MATERIALS AND METHODS: The available information published prior to August 2021 was reviewed via SciFinder, Web of Science, Google Scholar, PubMed, Elsevier, Wiley On-line Library, and The Plant List. The search was based on the ethnomedical remedies, pharmacological activities, bioactive compounds of dandelion for GI protection, as well as the interactions of the components in dandelion with the gut microbiota or biological regulators, and with other ingested bioactive compounds. The key search words were "Taraxacum" and "dandelion". RESULTS: T. coreanum Nakai, T. mongolicum and T. officinale are the most commonly used species for folkloric uses, with the whole plant, leaves and root of dandelion being used more frequently. GI-protective substances of dandelion include taraxasterol, taraxerol, caffeic acid, chicoric acid, chlorogenic acid, luteolin and its glucosides, polysaccharides, inulin, and ß-sitosterol. Dandelion products and derived constituents exhibit pharmacological effects against GI disorders, mainly including dyspepsia, gastroesophageal reflux disease, gastritis, small intestinal ulcer, ulcerative colitis, liver diseases, gallstones, acute pancreatitis, and GI malignancy. The underlying molecular mechanisms may include immuno-inflammatory mechanisms, apoptosis mechanism, autophagy mechanism, and cholinergic mechanism, although interactions of dandelion's constituents with GI health-related biological entities (e.g., GI microbiota and associated biological modulators) or other ingested bioactive compounds shouldn't be ignored. CONCLUSION: The review reveals some in vivo and in vitro studies on the potential of dandelion derived products as complementary and alternative medicines/therapeutics against GI disorders. The whole herb may alleviate some symptoms related GI immuno-inflammatory basing on the abundant anti-inflammatory and anti-oxide active substances. Dandelion root could be a nontoxic and effective anticancer alternative, owing to its abundant terpenoids and polysaccharides. However, research related to GI protective dandelion-derived products remains limited. Besides the need of identifying bioactive compounds/complexes in various dandelion species, more clinical studies are also required on the metabolism, bioavailability and safety of these substances to support their applications in food, medicine and pharmaceuticals.

OBJECTIVE: To analyze the effects of flower essence bouquets on the signs and symptoms of stress in nursing students. METHOD: Randomized clinical trial, triple blind, with two groups, flower essence group and placebo group, carried out with 101 nursing students. The groups used the formula for 60 days at a dosage of 4 drops 4 times a day. The outcome was evaluated using the Baccaro Test and the Perceived Stress Scale applied at the beginning and at the end of the intervention. The outcome analysis was performed using the mixed effects model, with 〈 = 5% and the effect size verified by the Cohen's d test. RESULTS: There was no significant difference between the groups in stress reduction (p > 0.05). Both groups showed a reduction in scale scores (p < 0.001) with large effect size. There was an influence of the COVID-19 pandemic in the reduction of Baccaro Test scores. CONCLUSION: The intervention with flower essence therapy was not more effective than placebo in reducing stress signs and symptoms. Brazilian Registry of Clinical Trials: UTN U1111-1257-5715.

BACKGROUND: Sucrose synthase (SUS, EC is one of the major enzymes of sucrose metabolism in higher plants. It has been associated with C allocation, biomass accumulation, and sink strength. The SUS gene families have been broadly explored and characterized in a number of plants. The pomegranate (Punica granatum) genome is known, however, it lacks a comprehensive study on its SUS genes family. METHODS: PgSUS genes were identified from the pomegranate genome using a genome-wide search method. The PgSUS gene family was comprehensively analyzed by physicochemical properties, evolutionary relationship, gene structure, conserved motifs and domains, protein structure, syntenic relationships, and cis-acting elements using bioinformatics methods. The expression pattern of the PgSUS gene in different organs and fruit development stages were assayed with RNA-seq obtained from the NCBI SRA database as well as real-time quantitative polymerase chain reaction (qPCR). RESULTS: Five pomegranate SUS genes, located on four different chromosomes, were divided into three subgroupsaccording to the classification of other seven species. The PgSUS family was found to be highly conserved during evolution after studying the gene structure, motifs, and domain analysis. Furthermore, the predicted PgSUS proteins showed similar secondary and tertiary structures. Syntenic analysis demonstrated that four PgSUS genes showed syntenic relationships with four species, with the exception of PgSUS2. Predictive promoter analysis indicated that PgSUS genes may be responsive to light, hormone signaling, and stress stimulation. RNA-seq analysis revealed that PgSUS1/3/4 were highly expressed in sink organs, including the root, flower, and fruit, and particularly in the outer seed coats. qPCR analysis showed also that PgSUS1, PgSUS3, and PgSUS4 were remarkably expressed during fruit seed coat development. Our results provide a systematic overview of the PgSUS gene family in pomegranate, developing the framework for further research and use of functional PgSUS genes.

Hibiscus sabdariffa, this beverage has been used for millennia as both a delicious cultural beverage and an ancient medicinal therapy. In recent years, many studies have investigated the uses and mechanisms of action of Hibiscus sabdariffa to treat common chronic diseases. In this literature review, we place the spotlight on Hibiscus sabdariffa's medical effect on common chronic diseases, the flower commonly used to make hibiscus tea. The databases PubMed, MEDLINE, Clinical Key, and CINAHL were searched for studies related to Hibiscus sabdariffa's compounds, antioxidative and anti-inflammatory features, mechanism of action on common chronic diseases including hypertension, hyperlipidemia, obesity, diabetes, and Alzheimer's disease. Hibiscus sabdariffa antihypertensive potentials originate from the vasodilator activity, diuretic efficacy, functionality as an ACE inhibitor, adipocyte differentiation inhibitor, heart rate reduction ability, and anti-inflammatory mechanistic. The antihyperlipidemic effect is dose-dependent and stems from the antioxidative effect and the activation of AMPK through phosphorylation and the inhibition of regulatory adipogenic transcription factors PPAR-γ, C/EBP-α, and SREBP-1c, which altogether results in lipid-lowering effect. As an antihyperglycemic, Hibiscus sabdariffa serves as anti-insulin resistance by inhibition of the phosphorylation of IRS-1 beside a similar effect to gliptins. Finally, Hibiscus sabdariffa was proven to protect against neuroinflammation in microglial cell culture exposed to LPS by decreasing IL-1, IL-6, TNF-α expression, and the protective effect against glucotoxicity, improve memory function by inhibiting the formation of hyperphosphorylated tau proteins in the mouse brain. Regular consumption of hibiscus tea or extract is beneficial for a reduction in chronic disease risk and diagnosis.Key teaching pointsHibiscus sabdariffa, or hibiscus, has been used for millennia as both a delicious cultural beverage and an ancient medicinal therapy.

Resultados La esencia floral reguló los factores que potencializan el dolor en el trabajo de parto, es decir, ruptura de las membranas amnióticas, fase activa e inducción del parto. Hubo aumento de los niveles de betaendorfina junto con la reducción de una contracción en mujeres con ruptura de las membranas ovulares y con inducción. Con relación al estrés, hubo constancia de los valores de cortisol en el grupo experimental, sin aumento de su valor en la fase activa, ruptura de las membranas ovulares o inducción. La esencia Five Flower demostró ser eficaz para la reducción de una hora y veinticinco minutos de tiempo de trabajo de parto en el grupo experimental. Conclusión La terapia floral realizada demostró ser eficaz en el control del dolor y del estrés durante el trabajo de parto, con un impacto positivo en su brevedad y en la cualificación de su desenlace.

Abstract Objective To evaluate the effectiveness of floral therapy associated with factors that strengthen pain and stress in the labor process through obstetric and neuroendocrine parameters. Methods Randomized, triple-blind, placebo-controlled clinical trial performed with 164 parturients at usual obstetric risk subdivided into two groups to which Five Flower floral essence and placebo were administered. Obstetric and neuroendocrine aspects were evaluated through biochemical analysis of the beta-endorphin and cortisol hormones through salivary samples before and after the intervention. Results The flower essence modulated the factors that strengthen pain in labor, that is, rupture of amniotic membranes, active phase and induction of labor. There was an increase in beta-endorphin levels along with one less contraction in women with ruptured ovular membranes and labor induction. Regarding stress, cortisol values were constant for the Experimental group, and did not change in the active phase, rupture of the ovular membranes or induction. The Five Flower essence proved to be effective in reducing labor time by 1 hour 25 minutes in the Experimental group. Conclusion The floral therapy used proved to be effective in controlling pain and stress during labor, and reflected positively on its agility and qualified its outcome.

Abstract Objective: To analyze the effects of flower essence bouquets on the signs and symptoms of stress in nursing students. Method: Randomized clinical trial, triple blind, with two groups, flower essence group and placebo group, carried out with 101 nursing students. The groups used the formula for 60 days at a dosage of 4 drops 4 times a day. The outcome was evaluated using the Baccaro Test and the Perceived Stress Scale applied at the beginning and at the end of the intervention. The outcome analysis was performed using the mixed effects model, with 〈 = 5% and the effect size verified by the Cohen's d test. Results: There was no significant difference between the groups in stress reduction (p > 0.05). Both groups showed a reduction in scale scores (p < 0.001) with large effect size. There was an influence of the COVID-19 pandemic in the reduction of Baccaro Test scores. Conclusion: The intervention with flower essence therapy was not more effective than placebo in reducing stress signs and symptoms. Brazilian Registry of Clinical Trials: UTN U1111-1257-5715.
