Abstract
The global increase in the incidence of wounds is concerning and fuels the search for new treatment options. The use of traditional medicinal plants in wound healing represents an appreciated available therapeutic possibility. This work introduces the VOLKSMED database, which contains plants and other materials used in Austrian folk medicine, either as monographs or mixtures. This work focuses on the monographs of the database. Concerning wound healing, Hypericum sp., Arnica montana, Calendula officinalis, Plantago sp., and Malva sp. are the most commonly used plants. The focus of this paper is set on selected lesser-known plants (Abies alba, Anthyllis vulneraria, Brassica sp., Gentiana sp., Larix decidua, Picea abies, Sambucus sp., Sanicula europaea) and their status quo in literature concerning wound healing. A systematic search using the databases SciFinder, SCOPUS, and PubMed yielded substantial evidence for the wound healing potential of Brassica sp., Gentiana sp., the Pinaceae A. abies, L. decidua, and P. abies, as well as Sambucus nigra. In vivo and clinical studies substantiate their use in Austrian folk medicine. According to the literature, especially A. vulneraria, Sambucus racemosa, and S. europaea would be worth investigating in-depth since data concerning their wound healing effects - even though scarce - are convincing. In conclusion, the VOLKSMED database contains promising opportunities for further treatment options in the field of wound healing. Future research should consider the listed plants to support their traditional use in Austrian folk medicine and possibly promote the implementation of old knowledge in modern medicine.

Abstract
This study aims to develop polylactic acid (PLA)-based packaging films with imparted antimicrobial properties and enhanced physical characteristics by evaluating the likely interaction among multiple film components. For this purpose; epoxidized soybean oil (ES) (20 %) serves as a plasticizer, spruce resin (SR) (15 %) functions as both a plasticizer and antimicrobial agent, ZnO (0.1 %) acts as a nanofiller and antimicrobial, and finally thyme and clove essential oil mixture (5 % and 10 %) serves as an antimicrobial agent were incorporated to PLA film formulation. Composite materials were prepared by the solvent casting method using methylene chloride as the solvent. The developed films were characterized in terms of physical, mechanical, thermal, and antimicrobial properties. Tensile strength (59 MPa) and elastic modulus (2625 MPa) of the neat PLA film gradually decreased to 8.99 MPa and 725.4 MPa, respectively, with the sequential addition of all components, indicating enhanced flexibility. SR, ZnO, and EOs significantly imparted antimicrobial property to the PLA film as demonstrated by the inhibition zone of 13.83 mm and 15.67 mm observed for E. coli and S. aureus, respectively. The barrier properties of the films were enhanced by the addition of SR and ZnO; however, EOs increased the water vapor permeability from 0.080 to 0.090 g.mm/m2.day.kPa compared to the neat PLA film. Principal component and hierarchical cluster analysis enabled the successful discrimination of the films, demonstrating how the film properties are affected by the film components. Therefore, this study suggests that selection of a proper combination is essential to highly benefit from the multicomponent film systems for designing alternative food packaging materials with desired properties.

Abstract
The aim of this study is to prepare new packaging materials with improved physical and antimicrobial properties that prevent the growth of microorganisms. Poly(L-lactic acid) (PLA) based packaging films were prepared by the solvent-casting method using spruce resin (SR), epoxidized soybean oil, an essential oil mixture (calendula and clove oil), and silver nanoparticles (AgNPs). The AgNPs were synthesized by the polyphenol reduction method, using spruce resin dissolved in methylene chloride. The prepared films were tested for antibacterial activity and physical properties, such as tensile strength (TS), elongation at break (EB), elastic modulus (EM), water vapor permeability (WVP), and UV-C blocking effect. The addition of SR decreased the water vapor permeation (WVP) of the films, whereas the addition of essential oils (EOs) increased this property due to their higher polarity. The morphological, thermal, and structural properties were characterized using SEM, UV-Visible spectroscopy, FTIR, and DSC. The agar disc well method showed that SR, AgNPs, and EOs imparted antibacterial activity to the PLA-based films against Staphylococcus aureus and Escherichia coli. Multivariate data analysis tools, such as principal component and hierarchical cluster analysis, were used to discriminate PLA-based films by simultaneously evaluating their physical and antibacterial properties.

Abstract
The main component of rosin natural gum is abietic acid, which has an interesting chemical structure to be studied with the influence of gamma-ray and the antimicrobial activity on the properties of a cheap abundant solid state natural material of rosin. Rosin is exposed to a wide scale of gamma-ray ranges from 0 to 100 kGy. The changes in the properties are tracked by various techniques of FTIR, XRD, TGA, GPC, and SEM. The molecular weight of rosin changes from 370 g/mol to higher and the morphological properties were investigated. The irradiated rosin acid (IRA) at different irradiation doses exploited antimicrobial effect versus Gram-positive and Gram-negative as well. The inhibition zone enhanced from 15 to 33, 14 to 28, 14 to 20, and 9 to 14 mm for Gram-positive and Gram-negative, respectively. Moreover, bioactive behavior for irradiated rosin of 40 kGy recorded the highest antibacterial activity against both types of bacteria. The outcome data of antimicrobial activity are good and confirm that there is a significant effect of irradiation dose on the biocidal activity of rosin.

Abstract
The rise of methicillin-resistant Staphylococcus epidermidis (MRSE) makes it difficult to treat infections that increase morbidity and mortality rates in various parts of the world. The study’s objectives include identifying the clinical prevalence, antibiogram profile, and Gompertz growth kinetics of MRSE treated with synthetically created nanoparticles of rosin obtained from Pinus roxburghii. A total of 64 of 200 clinical isolates of S. epidermidis (32% of the total) displayed sensitivity (40.62%) and resistance (59.37%) to seven different antibiotic classes. The most sensitive patterns of antibiotic resistance were seen in 20 (78.95%) and 24 (94.74%) isolates of MRSE against piperacillin/tazobactam and cephradine, respectively. Fosfomycine was found to be the most effective antibiotic against MRSE in 34 (89.47%) isolates, followed by amoxicillin. Successfully produced, described, and used against MRSE were rosin maleic anhydride nanoparticles with a size range of 250 nm to 350 nm. Five different concentrations of 25, 50, 75, 100, and 150 mg mL−1 rosin maleic anhydride nanoparticles were investigated to treat MRSE resistance. According to Gompertz growth kinetics, the maximal growth response was 32.54% higher and the lag phase was also 10.26% longer compared to the control when the amount of rosin maleic anhydride nanoparticles was increased in the MRSE. Following the application of rosin maleic anhydride nanoparticles, the growth period is extended from 6 to 8 h. A potential mechanism for cell disintegration and distortion is put forth. This investigation came to the conclusion that rosin maleic anhydride nanoparticles better interfere with the surface of MRSE and demonstrated a preferred bacteriostatic action.

Abstract
INTRODUCTION Onychomycosis is notoriously difficult to treat. While oral antifungals are the most efficacious treatment for onychomycosis, they are contraindicated in certain patient populations, and patients may desire lower risk and accessible alternatives to systemic agents. In this study, we examine the clinical evidence supporting the use of complementary and alternative therapies in the treatment of onychomycosis. METHODS PubMed, Embase, and Cochrane Library were searched for clinical trials, observational studies, and case reports/case series, examining the efficacy of a complementary or alternative therapy for the treatment of onychomycosis. RESULTS We identified 17 articles studying a complementary and alternative therapy for onychomycosis, including tea tree oil (n = 5), Ageratina pichinchensis (n = 3), Arthrospira maxima (n = 2), natural coniferous resin lacquer (n = 2), Vicks VapoRub® (n = 2), propolis extract (n = 2), and ozonized sunflower oil (n = 1). CONCLUSION Given the rise of antifungal resistance, complementary and alternative therapies should continue to be studied as adjunctive or alternative therapy for onychomycosis. While preliminary evidence exists for several complementary and alternative therapies in the treatment of onychomycosis, large-scale, randomized, placebo-controlled trials are needed prior to endorsing their use to patients.

Abstract
This study aimed to evaluate the efficacy of Norway spruce ointments on wound healing of castration wounds in piglets. This study included 95 male pigs randomly divided into five treatment groups: Norway spruce balm (Vulpuran), Norway spruce resin (Abilar), pork lard (ointment base of Vulpuran), no treatment (negative control) and antibiotic blue spray (Cyclo spray, positive control). Wound healing parameters (such as healing time, wound size, reddening of wound edges and surrounding, swelling, secretion and wound contamination), microbiological status and the haptoglobin level as an inflammation parameter were investigated. In the Norway spruce groups, some positive effects on wound healing parameters were found. In the first 6 days of treatment, Abilar or Vulpuran showed the smallest means of wound areas, and at the end of the study (day 15 + 17), the highest rates of completely closed wounds compared to the other groups. Vulpuran treatment led to significantly lower wound secretion (p = 0.003) and wound contamination (p = 0.015) than the untreated control did. Furthermore, the microbiological status was determined using MALDI-TOF-MS and partial 16S rRNA gene sequencing at different days of treatment. A comparison of the five treatment groups on day 3 revealed that Norway spruce led to the lowest rate of wounds colonised with fungi, mainly classified into genus Candida, (Abilar 77%, Vulpuran 70%) in comparison with blue spray (89%), lard (100%) and untreated control (100%). Fungi could only be detected in one of the 13 samples treated with Vulpuran on day 8, which nearly reached significance (p = 0.055).

Abstract
Onychomycosis is a chronic disorder that is difficult to manage and hard to eradicate with perilous trends to relapse. Due to increased prevalence of HIV, use of immunosuppressant drugs and lifestyle-related factors, population affected with fungal infection of nail (Onychomycosis) happens to increase extensively in last two decades. Modalities available for the treatment of onychomycosis include systemically administered antifungals, mechanical procedures, and topical drug therapy. But the efficacy of the most of approaches to deliver drug at targeted site, i.e., deep-seated infected nail bed is limited due to compact and highly keratinized nail structure. A series of advanced formulation approaches, such as transfersomes, liposomes, nano/micro emulsion, nail lacquers etc., have been attempted to improve the drug penetration into nail plate more efficiently. The manuscript reviews these formulation approaches with their possible mechanisms by which they improve the drug penetration.Comparative analysis of available treatment modalities for onychomycosis has been provided with pros and cons of each alternatives. Additionally, ongoing research about the application of biological materials such as modified cationic antimicrobial peptides (AMPs), plant-derived proteins, and synthetic antimicrobial peptidomimetics have also been explored.

Abstract
Onychomycosis is an increasingly common fungal nail infection, chiefly caused by dermatophyte fungi. The disease is notoriously difficult to treat due to the deep-seated nature of fungi within the nail plate, prolonged treatment requirements, poor patient adherence and frequent recurrences. Given the poor efficacy of currently available topical and systemic therapies, there is a renewed interest in exploring alternative treatment modalities for onychomycosis. Natural therapies, physical treatments and various combination therapies have all shown potential for the management of onychomycosis, though research on many of these methods is still in preliminary stages. Further large, well-designed, randomised controlled trials are necessary to confirm the efficacy of these novel treatments in order to make formal recommendations regarding their use in the management of onychomycosis.

Abstract
Significance: The treatment of chronic wounds results in an enormous drain on healthcare resources in terms of workload, costs, frustration, and impaired quality of life, and it presents a clinical challenge for physicians worldwide. Effective local treatment of a chronic wound has an important role, particularly in patients who are-because of their poor general condition, diminished life expectancy, or unacceptable operative risk-outside of surgical treatment. Recent Advances: Since 2002, our multidisciplinary research group has investigated the properties of Norway spruce (Picea abies) resin in wound healing and its therapeutic applications in wound care. Resin is a complex mixture of resin acids (e.g., abietic, neoabietic, dehydroabietic, pimaric, isopimaric, levopimaric, sandrakopimaric, and palustric acids) and lignans (e.g., pino-, larici-, matairesinol, and p-hydroxycinnamic acid) having substantial antimicrobial, wound-healing, and skin regeneration enhancing properties. Critical Issues: The cornerstone in successful wound care is an efficient causal treatment of the underlying co-morbidities, for example, diabetes, malnutrition, vascular- or certain systemic diseases. However, definitive diagnosis and specific therapy of a chronic wound is often difficult, because the etiology is practically always multi-factorial, and in the chronic phase, confounding factors such as infections invariably impede wound healing. Future Directions: To study the exact molecular mechanism of actions by which resin promotes cellular regeneration and epithelialization during the wound-healing process. To investigate potential antimicrobial properties of resin against the most ominous multidrug-resistant beta-lactamase (including carbapenemases and metallo-β-lactamases) producing bacteria, and to individualize those pharmacologically active compounds which are responsible for the antimicrobial activity of resin.

Abstract
Background Distal and lateral onychomycoses are the most frequent forms of onychomycosis, causing subungual hyperkeratosis that usually limits local penetration of antimycotic drugs. Tazarotene exerts anti-inflammatory and immune-modulating activities toward both infective agents and damaged keratinocytes. Given the well-documented efficacy of tazarotene on hyperkeratotic nail psoriasis, we investigated its therapeutic use in onychomycosis. Patients and methods We designed a preliminary open clinical trial in patients affected by distal and lateral subungual onychomycosis of the toenails and verified the fungistatic activity of tazarotene in vitro. Fifteen patients were treated with topical tazarotene 0.1% gel once per day for 12 weeks. Mycological cultures and potassium hydroxide stains of nail samples were performed at the beginning and at the end of the study. Treatment was considered effective when clinical healing and negative mycological culture were obtained. Onycholysis, nail bed discoloration, and subungual hyperkeratosis were measured using standardized methodologies and analyzed by means of Mann–Whitney test and analysis of variance. Fungistatic activity of tazarotene was evaluated by disk diffusion assay. Results Six patients (40%) reached a mycological cure on target nail samples already after 4 weeks of treatment. Complete clinical healing and negative cultures were reached in all patients at week 12, with a significant improvement of all clinical parameters of the infected nails. Disk diffusion assay after 48 hours of incubation with tazarotene solution showed a central area of inhibition in all examined fungal cultures. Conclusion Our results documented a good clinical outcome using topical tazarotene 0.1% gel in distal and lateral subungual onychomycosis and its fungistatic activity of tazarotene in vitro. The majority of patients appeared cured at a 6-month follow-up. The efficacy and safety of tazarotene must be confirmed on a larger number of patients, although already documented in nail psoriasis patients often affected by onychomycosis.

Abstract
BACKGROUND Managing toenail onychomycosis with topical treatments is challenging. It is difficult for topical medication to penetrate the nail plate, and this is reflected in lower cure rates with topical treatment than with oral treatment. However, oral medications may not be suitable for some patients, because of drug interactions; therefore, topical treatments are critical in managing the disease in certain patient populations. OBJECTIVE This paper reviews the quality and content of the scientific literature on topical treatments for toenail onychomycosis. METHODS PubMed, Ovid (Medline and Embase), Scopus, Cochrane library, and clinicaltrials.gov databases were searched for original clinical reports of topical monotherapy for microscopy and/or culture-confirmed toenail onychomycosis in adults. Studies were evaluated using an onychomycosis study quality scale, which was based on the CONSORT guidelines. RESULTS Twenty-five publications (28 studies) were identified and met the inclusion criteria. Thirteen studies scored high ratings on the quality scale. These were randomized controlled trials or randomized comparative trials. Low-quality studies were nonrandomized, open studies that prevented statistical analysis. Most studies reported clinical and mycological cure. The most variation was observed with reporting outcomes of clinical improvement. Amorolfine, ciclopirox, tavaborole, and efinaconazole produced clinical and mycological cure in patients with mild to moderate toenail onychomycosis (<50-65 % nail involvement), with efinaconazole showing the highest rates. Treatments were generally applied daily for 24-48 weeks, with longer treatment and follow-up showing better outcomes. CONCLUSION Topical treatment with amorolfine, ciclopirox, tavaborole, or efinaconazole is appropriate for cases of mild to moderate toenail onychomycosis due to dermatophyte or mixed dermatophyte/Candida infection.
