Abstract:

Four different solvents, ethyl acetate, ethanol, petroleum ether, and hexane, were used for the multistage solvent extraction of rose concrete oil from the aromatic plant species of Rosa x damascena. The components present in the concrete oils were analyzed using Gas Chromatography-Mass Spectrometer. After the multistage solvent extraction process, the solvent was removed by using a rotary vacuum evaporator. Methyl alpha d-glucopyranoside, 5-hydroxy methyl furfural, 2,3-butanediol, and ethyl-d glucopyranoside were the major components identified using ethyl acetate ethanol, hexane, and petroleum ether as a solvent, respectively. The phenyl ethyl alcohol and 5-hydroxymethyl furfural were identified as the repeated components in all four solvents. The solvent ethanol showed a different composition when compared to the other three solvents. A high yield was obtained when ethanol was used as a solvent. The type of solvent used significantly impacts the compositions of the concrete oil of Rosa x damascena.

Abstract:

Rosa x damascena Herrm. represents one of the most popular and important plants of the Rosaceae family. For ages, rose oil, rose water and extracts from its flowers were used in perfumery, cosmetics, aromatherapy, and medicine due to diverse pharmacological efficacy. Nowadays, special attention is paid to the valorization of wastes from the rose oil industry in order to fully recover potent biologically active compounds. The present study describes in detail the microstructural features of the flower petals and provides data on chemical composition and biological potency of the aqueous extract of rose oil waste from the R. damascena Georgian cultivar. Up to 25 constituents were detected by HPLC-MS in the extract, and the content of total flavonoids in the extract reaches 2.29%. Amongst them hyperoside is dominating, which content is not less than 1%. Pharmacological evaluation of the extract on "Hot plate" and carrageenan-induced oedema models in mice revealed analgesic (42%) and anti-inflammatory (67%) effects of the extract. As well, the extract revealed antiplasmodial activity against Plasmodium falciparum (3D7) strain (IC50 =20.31 µg/mL)

Abstract:

The present study reports the development of a DNA marker tightly linked to the double flower (DF) phenotype in R. × damascena, suitable for marker assisted breeding. The development of this marker is based on previous identification of genome region associated with the DF phenotype in R. × damascena and recent studies demonstrating involvement of the AP2/TOE gene in the formation of DF in several species from the Rosaceae family. We identified a polymorphic region named RdDF upstream of the AP2/TOE gene in R. × damascena and used the sequence data for designing PCR primers. Segregation analysis of the four alleles of RdDF in a population of 104 plants obtained after self-pollination of R. × damascena showed that one of the alleles (RdDF-B, 203 bp) is tightly linked to the DF phenotype. Analysis of the segregation of two SSR markers located at a distance of approximately 1578 kb and 1129 kb on both sides of RdDF, showed that walking away from the developed RdDF marker results in the observation of simple flower recombinant plants, supporting association of RdDF with the DF phenotype. The application of the developed RdDF marker for marker assisted selection (MAS) and breeding programmes involving R. × damascena, as well as further study of the molecular base of DF formation in this species are discussed.

Abstract:

Among Rosaceae family's most popular and important plants Rosa x damascena Herrm. holds one of the top places due to its centuries-long application in perfumery, cosmetics, aromatherapy and medicine. Despite this, the chemical and pharmacological study of different products obtained from R. damascena still does not lose its relevance. Currently, considerable attention is paid to the valorization of the waste from rose oil production in order to fully utilize valuable physiologically active constituents. The present study provides data on some pharmacological properties of the aqueous extract of rose oil waste from the R. damascena cultivated in Georgia. In particular, evaluation of gastro- and hepatoprotective activity of the aforesaid extract has been carried out in animal models and revealed its efficacy. The extract appeared to dose dependently stimulate leucopoiesis (up to 75%) and prevent ethanol-induced gastric injury (20-80%). As well, the extract ameliorated hepatoxic effects of carbon tetrachloride by 63%.

Abstract:

Miniature potted rose and Damask rose are important commercial plant cultivars in ornamental horticulture. Root suckers are common rose propagation method, but it is slow and seasonally dependent. In this survey, the propagation of nodal explants of these two species was studied through in vitro regeneration system. 16 and 24 different media were used for study of shoot and root regeneration respectively. The axillary buds were sprouted earlier in miniature rose than R. damascena. Shoot induction and proliferation (shoot ramification and growth) were observed 5 and 17 days after planting in miniature rose and 16 and 38 days in R. damascena respectively. The highest shoot proliferation obtained in media 3 and 7 in miniature rose, and medium 16 for R. damascena. These three media were recorded as optimal media with 100 % shoot proliferation. In these media, root initiation and growth of miniature rose (respectively after 78 and 92 days) was earlier than Damask rose (respectively 125 and 138 days). The successful rooting occurred in three and two media for miniature and Damask rose respectively. Rooting frequency was higher in the half strength MS liquid media than the others. Thus, cultivar potted rose as a modern species is propagated easier than old rose (R. damascena).

Abstract:

The present work aims to evaluate Rosa x damascena Herrm. and Pelargonium graveolens L’Hér. essential oils, and the major constituent geraniol for their in vitro and in silico inhibitory activities against 5-lipoxygenase (5-LOX), cyclooxygenase (COX), acetyl cholinesterase (AChE), butyryl cholinesterase (BuChE), and angiotensin converting enzyme (ACE2) enzymes. Geraniol most potently inhibited the ACE2 relative to other enzymes. R. damascena essential oil moderately inhibited the cancer cell lines with no toxic effects on healthy HEK 293 cells. P. graveolens essential oil inhibited a number of cancer cell lines including A549, MCF7, PC3, and HEK 293 that are reported here for the first time. The molecular docking of geraniol with the target enzymes revealed that it binds to the active sites similar to that of known drugs. Geraniol carries the potential for further drug development due to its drug-like binding mode for the target enzymes. Our work confirms that these essential oils possess similar biological activities due to their similar phytochemistry in terms of the major constituents of the plants. The promising biological activities reported in this work further warrant the inclusion of in vivo studies to establish safe use of the target essential oils and their constituents.

Abstract:

Rosa x damascena Mill. essential oil is mainly used in the cosmetics and perfumery industry, but it also finds application in the food industry as a flavoring agent. The chemical composition of essential oils is affected by environment, soil, harvesting technique, storage condition, and extraction methods. Nowadays, the study and design of greener, more efficient, and sustainable extractive procedures is the main and strategic focus in the chemical research and development of botanical derivatives, especially as regards fragrances and essential oils. Several technologies are available, and the best method to use depends on the desired chemicals, but conventional extractive processes are often laborious and time-consuming, involve large amounts of solvents, and may cause the partial loss of volatiles, affecting the quality of the final product. In the last decade, microwave irradiation has been successfully applied to classical techniques, often improving the general extractive efficiency and extract quality. In the present paper, as a preliminary analytical screening approach, two microwave-mediated techniques, Solvent-Free Microwave Extraction (SFME) and Microwave Hydrodiffusion and Gravity (MHG), and two conventional procedures, Hydrodistillation (HD) and Steam Distillation (SD), were applied and compared for the extraction of volatile compounds from R. x damascena fresh petals to highlight differences and advantages of the selected procedure and of the obtained extracts useful in a cosmetic context as fragrances or active ingredients. The chemical composition of the extracts was investigated by GC-MS and GC-FID. Sixty-one components, distributed in the four techniques, were identified. SD and HD are dominated by oxygenated terpenes (59.01% and 50.06%, respectively), while MHG and SFME extracts are dominated by alcohols (61.67% and 46.81%, respectively). A relevant variability in the composition of the extracts relating to the extraction techniques used was observed. To point out the correlation between the process and composition of the obtained natural products, principal component analysis (PCA) of the data extracted from GC-FID was used. Taking into account a cosmetic application, SFME shows several advantages when compared with the other procedures. The extract (obtained in a significantly higher amount) contains a meaningful lower level of potential fragrance allergenic compounds and quite a double amount of benzyl alcohol and 2-phenyl ethanol that can also enhance the preservative action in personal care products.

Abstract:

Since sialidase is a pathogenicity factor in certain microbes, it is important to inhibit it as this could have both preventative and therapeutic impacts on a number of diseases. Viral sialidase inhibitors have pre¬viously produced significant effects, but there are few experiments of the same kind on bacterial enzymes. The ability of some extracts from Bulgarian plants to inhibit the sialidases of Vibrio cholerae non-O1, Arthrobacter nicotianae, and Oerskovia paurometabola was investigated. Extracts from Rosa damascena, essential oil from Origanum vulgare ssp. hirtum and acetone exudate from Helichrysum arenarium were found to have an inhibitory effect on the studied enzymes. The influence of the extracts on bacterial siali¬dase activity was investigated for the first time. It was found that 5% Triton X-100 used for extract dilution has inhibitory effect on sialidase produced from O. paurometabola (76%), from V. cholerae non-O1 (30%) and has no effect on A. nicotinae.

Abstract:

Concrete oil was extracted from Rosa x damascena using different percentage ratios of solvents (petroleum ether and ethanol) by the Soxhlet extraction method. The extraction was carried out using petroleum ether and ethanol in five different percentage ratios of (v/v) (100:0, 75:25, 50:50, 25:75, 0:100) (petroleum ether:ethanol). The rotary vacuum evaporator was used to separate concrete oil and the solvents. The extracted concrete oil was analyzed using gas chromatography-mass spectrometry (GC-MS) technique. The obtained results show that many new compounds were identified, at two different solvents and its ratios. Phenylethyl alcohol in the percentages of (61.71%), (10.07%) and (25.92%) was obtained as a major compound with the solvent percentages of (100:0), (50:50) and (75:25) (PE:E), respectively. Hexacosane (37.2%) was identified as a major compound when pure ethanol is used as a solvent. The highest number of components were identified (totally 93 components) when an equal percentage (50:50) of petroleum ether and ethanol were mixed. The usual monoterpenes components, e.g. geraniol, nerol, citronellol and linalool, were not found in the present extraction study. This study concludes that the compositions of concrete oil were mainly influenced by the type of solvents and its ratios used for the extraction

Abstract:

AbstractNatural raw materials such as essential oils have received more and more attention in recent decades, whether in the food industry, as flavorings and preservatives, or as insecticides and insect repellents. They are, furthermore, very popular as fragrances in perfumes, cosmetics, and household products. In addition, aromatherapy is widely used to complement conventional medicine. This review summarizes investigations on the chemical composition and the most important biological impacts of essential oils and volatile compounds extracted from selected aromatic blossoms, including Lavandula angustifolia, Matricaria recutita, Rosa x damascena, Jasminum grandiflorum, Citrus x aurantium, Cananga odorata, and Michelia alba. The literature was collected from PubMed, Google Scholar, and Science Direct. Blossom essential oils discussed in this work are used in a wide variety of clinical issues. The application is consistently described as safe in studies and meta-analyses, although there are notes that using essential oils can also have side effects, especially dermatologically. However, it can be considered as confirmed that essential oils have positive influences on humans and can improve quality of life in patients with psychiatric disorders, critically ill patients, and patients in other exceptional situations. Although the positive effect of essential oils from blossoms has repeatedly been reported, evidence-based clinical investigations are still underrepresented, and the need for research is demanded.

Abstract:

This study attempts to utilize newly developed machine learning techniques in order to develop a general prediction algorithm for agricultural soils in Saudi Arabia, specifically in the Taif region. Energy dispersive X-ray fluorescence (EDXRF) measurements were used to develop national predictive models that predict the concentrations of 14 micronutrients in soils of Taif rose farms, for providing high-quality data comparable to conventional methods. Machine learning algorithms used in this study included the simple linear model, the multivariate linear regression (MLR); and two nonlinear models, the random forest (RF) and multivariate adaptive regression splines (MARS). Our study proposes a machine learning (ML) strategy for predicting fertility parameters more accurately in agricultural soils using 10 farms of the Taif rose (Rosa damascena) in Taif, Saudi Arabia as a case study. Results demonstrated that MARS provides higher prediction performance when the number of explanatory variables is small, while RF is superior when the number of variables is large. On the other hand, the MLR is recommended as a moderate method for predicting multivariate variables. The study showed that multivariate models can be used to overwhelm the drawbacks of the EDXRF device, such as high detection limits and an element that cannot be directly measured.

Abstract:

Damask roses (Rosa x damascena) are widely used in cosmetics and pharmaceutics. Here, we established an in vitro suspension cell culture for calli derived from damask rose petals. We analyzed rose suspension cell transcriptomes obtained at two different time points by RNA sequencing to reveal transcriptional changes during rose suspension cell culture. Of the 580 coding RNAs (1.3%) highly expressed in the suspension rose cells, 68 encoded cell wall-associated proteins. However, most RNAs encoded by the chloroplasts and mitochondria are not expressed. Many highly expressed coding RNAs are involved in translation, catalyzing peptide synthesis in ribosomes. Moreover, the amide metabolic process producing naturally occurring alkaloids was the most abundant metabolic process during the propagation of rose suspension cells. During rose cell propagation, coding RNAs involved in the stress response were upregulated at an early stage, while coding RNAs associated with detoxification and transmembrane transport were upregulated at the late stage. We used transcriptome analyses to reveal important biological processes and molecular mechanisms during rose suspension cell culture. Most non-coding (nc) RNAs were not expressed in the rose suspension cells, but a few ncRNAs with unknown functions were highly expressed. The expression of ncRNAs and their target coding RNAs was highly correlated. Taken together, we revealed significant biological processes and molecular mechanisms occurring during rose suspension cell culture using transcriptome analyses.

Abstract:

Aromatherapy is a practice applied in different sectors such as post-operative care, pain treatment and anxiety reduction. However, in Brazil, the legislation allows the use of aromatherapy by nurses since 2018, but the use of essential oils during labor is not regulated. The aim of the study was to analyze the records of the benefits of using aromatherapy during labor and the chemical components of aromatic plants that contribute to the reducing pain, duration of contractions, anxiety and stress effects resulting from childbirth. The integrative review carried out in the Scopus, MEDLINE / PubMed and Science Direct databases specified between 2010 and 2020, in Portuguese, English and Spanish. The PICo methodology (Population, Interest and Context) was used to construct the research question and select controlled and uncontrolled descriptors, which were combined with the Boolean operators "AND", "OR" and "NOT". 17 articles were selected using aromatherapy during labor, individually or in conjunction with other therapies. The most used essential oil was Lavandula officinalis (53%), and the effects were related to the decrease in the pain of contractions and childbirth, followed by Rosa x damascena oil (23.5%), although the effect of the plant is more related to the reduction in the parturient’s anxiety and stress. Aromatherapy acts both on the physiological aspects of women in labor and on their subjectivity. Chemical evidence supports the relationship between the major compounds present in the essential oils of the aromatic plants used in the study and the beneficial effects of aromatherapy in labor.

Abstract:

The considerable risk of adulteration in the herbs has raised commercial interest in the identification of medicinal herbs globally. DNA barcoding is the primary techniques for identifying the herbs at genetic level. This technique's key benefit is that it can identify the material's purity. This study focuses on the accurate identification of species utilizing Polymerase chain reaction-based nuclear universal internal transcribed spacer region (a barcode region) amplification and sequencing in 2 medically significant plants (Rosa damascene and Prunus dulcis) procured from the local herbal market of Karachi in the year 2022. Results suggest that the ribosomal nuclear ITS2 region of the selected plant species shows the 100 % identity with the reference genome, therefore it has shown a good rate of identification at the species level. The findings of this concludes that ITS2 is the novel standard barcode that involve in species identification, genomic conservation, and secure utilization of the medically significant plant species.

E-mail: lara_marques8@hotmail.com 1 RESUMO Devido suas propriedades medicinais e por ser um alimento rico em antioxidantes, o consumo da hortaliça berinjela vem crescendo. Durante o cultivo da berinjela, o manejo da água e do solo são fatores que podem influenciar a qualidade do fruto. Assim, objetivou-se com este trabalho analisar as características físico-químicas do fruto da berinjela ‘Florida Market’ irrigada com águas salobras por gotejamento contínuo e pulsos. O experimento foi conduzido em ambiente protegido com delineamento experimental em blocos casualizados, em esquema fatorial 2 x 4, com cinco repetições. Os tratamentos consistiram de duas formas de aplicação de água: gotejamento contínuo e pulsos, com quatro níveis de condutividade elétrica da água – CEa (0,3 (controle); 1,5; 3,0 e 4,5 dS m-1). Foram avaliadas as variáveis: massa fresca do fruto, teor de sólidos solúveis totais, pH da polpa, acidez total titulável e relação sólidos solúveis totais/acidez total titulável. Com o incremento da salinidade da água de irrigação o teor de sólidos solúveis totais (+3,60%) e acidez total titulável (+9,87%) aumentaram, enquanto a relação de sólidos solúveis totais/acidez total titulável (-4,53%) e a massa fresca do fruto diminuíram. A interação entre a salinidade e a forma de aplicação da água não influenciou as características físico-químicas do fruto. Palavras-chave: Solanum melongena L., salinidade, sólidos solúveis, acidez titulável. DAMASCENO, L. F.; BELO, L. R. M.; GHEYI, H. R.; COVA, A. M. W.; LIMA, G. S. de; MARQUES, L. de J. QUALITY OF EGGPLANT FRUIT IRRIGATED WITH BRACKISH WATER UNDER CONTINUOUS DRIP AND PULSE IRRIGATION 2 ABSTRACT Due to its medicinal properties and to be a functional food rich in antioxidants, the eggplant vegetable consumption has been increasing. During eggplant cultivation, water and soil management are factors that can influence fruit quality. Therefore, this work aimed to analyze the physico-chemical characteristics of the fruit of the eggplant ‘Florida Market’ irrigated with brackish water under continuous drip and pulse irrigation. The experiment was conducted in protected environment in a randomized block design, adopting a 2 x 4 factorial scheme, with five replicates. The treatments consisted of a combination of two forms of application of brackish water: continuous drip and pulses, with four levels of water salinity - ECw (0.3 (control); 1.5; 3.0 and 4.5 dS m-1). The variables evaluated were fresh weight of the fruit, total soluble solids content, pH of the pulp, total titratable acidity and the ratio of total soluble solids/total titratable acidity. With the increase in salinity of irrigation water the content of total soluble solids (+3.60%) and total titratable acidity (+9.87%) increased, while the ratio of total soluble solids/total titratable acidity (-4.53%) and fresh fruit mass decreased. The interaction between salinity and the form of water application did not influence the physico-chemical characteristics of the fruit. Keywords: Solanum melongena L., salinity, soluble solids, titratable acidity.

Abstract:

A fragment of 772 bp of the chloroplast maturase K gene was amplified and sequenced for Rosa x damascena trigintipetala variety growing in Taif region of Saudi Arabia. The data were aligned with their counterparts of other varieties already found in the Genbank database and were analyzed by maximum-parsimony, neighbor-joining and maximum-likelihood methods and a single rooted tree was executed. R. x damascena trigintipetala was paraphyletic where one sample [A] clustered with all varieties while the second [B] was basal. R. x damascena was sister to R. x chinensis semperflorens with the later being basal. R. x damascena gori was basal for all taxa studied. R. moschata was inside the clade of R. x damascena. Hybridization could be possible among R. damascena, R. chinensis and R. moschata. The genetic distance and tree topology indicated that [A] variety could be originated from R. moshata while [B] could be originated from gori or R. chinensis semperflorens. We, therefore, may consider that R. x damascena gori or R. chinensis could be the origin of all nowadays R. x damascena varieties.

Abstract Background One of the most widely used medicinal plants in Iranian traditional medicine, Rosa × damascena Herrm. (mohammadi flower) that the people of Kashan use as a sedative and to treat nervous diseases and constipation. In this research, the yield, chemical composition and antimicrobial activity of the essential oil of this plant were evaluated for the first time from Azaran region, Kashan. Methods The essential oil was extracted by means of hydrodistillation (Clevenger), and its chemical compounds were identified and determined by GC/MS. The antimicrobial activity of the essential oil was determined by the diffusion method in agar, the minimum growth inhibitory concentration (MIC) and the minimum concentration capable of killing bacterial/fungal microorganisms (MBC/MFC). Results The results showed that the yield of essential oil was 0.1586 ± 0.0331% (w/w). Based on the results of the chemical composition analysis of R. x damascena essential oil, 19 different compounds (98.96%) were identified. The dominant and main components of the essential oil were oleic acid (48.08%), palmitic acid (15.44%), stearic acid (10.17%), citronellol (7.37%) and nonadecane (3.70%). Based on the results of diffusion in agar, the highest zone of inhibition against Candida albicans (ATCC 10231) was ~ 9.5 mm. The strongest inhibitory activity of R. x damascena essential oil against Gram-negative Proteus mirabilis (ATCC 43071) was with the diameter of the inhibition zone (~ 9 mm), which was equal to the strength of rifampin (~ 9 mm). Conclusion Therefore, this essential oil is a promising natural option rich in fatty acids, which can be a potential for the production of natural antimicrobials against infectious diseases, especially urinary tract infections.

Abstract:

AbstractDamask rose is a well-established, abundant source of phytochemicals, as well as economically important essential oil—however, its cultivation is demanding and costly. In this paper, extracts from four raw plant materials—Salvia officinalis, Sambucus nigra, Matricaria chamomilla, Calendula officinalis, known to be rich in phenolic compounds, but also far easier to cultivate—were directly compared to those obtained from Rosa × damascena Mill. By combining diverse extraction methodologies (in a Soxhlet apparatus, ultrawave-assisted and microwave-assisted, using supercritical CO2) and complementary in vitro assays (radical scavenging, iron reducing, Folin–Ciocalteau and Al3+ complexation), it was possible to conveniently approximate and compare the phytochemical portfolios of those diverse plants. By factoring in the crop yields of different species, economically important conclusions can be reached—with pot marigold (C. officinalis) seemingly the most viable substitute for damask rose as a source of phenolics. Fatty acid and microelement analyses were also performed, to further enrich the chemical profiles of plant extracts. The paper also aims to collate and redesign multiple colorimetric assays frequently used while studying plant extracts in vitro, but criticized for their lack of correlation to in vivo activity. We show that they remain a viable tool for direct comparison of extraction methodologies, while highlighting their shortcomings.

Bu çalışmada, su stresin altında yağ gülü (Rosa x damascena Mill.) fidanlarında meydana gelen morfolojik ve biyokimyasal değişimlerin belirlenmesi amaçlanmıştır. Üç farklı sulama seviyesi, serada polietilen tüpler içerisinde bulunan bir yaşlı yağ gülü fidanlarına sekiz hafta boyunca uygulanmıştır. Bunlar; kontrol olarak tam sulama (saksı tarla kapasitesinin (STK) %100’ü) ve iki farklı seviyede kısıtlı su uygulaması (STK’nin %50'si ve STK’nin %25'i). Eksilen su miktarı her 3 günde bir verilmiştir. Çalışmada deneme sonunda; fidan boyu, sürgün sayısı, gövde çapı, yaprak alanı ve SPAD değerleri ölçülmüştür. Denemenin 35., 57. ve 75. günlerinde yapraklarda klorofil a, klorofil b, klorofil a+b, toplam fenolik madde ve toplam flavonoid içerikleri analiz edilmiştir. Çalışmadan elde edilen verilere göre fidan boyu ve yaprak SPAD değerleri kontrol uygulamasında (%100 SK) nispeten yüksek (sırasıyla 74.13 cm ve 40.86) saptanmıştır. En yüksek sürgün sayısı %25 SK uygulamasında (1.55 adet/bitki) belirlenmiştir. %50 STK ve %25 STK uygulamaları kontrol uygulamaya göre her üç analiz döneminde de klorofil a, klorofil b ve klorofil a + b, toplam fenolik ve toplam flavonoid içeriklerini önemli ölçüde düşürmüştür. 35. gün analiz sonuçlarına göre 75. gün analizlerinde klorofil içerikleri korunurken, toplam fenolik ve flavonoid içeriklerinde azalma saptanmıştır.

Abstract:

Abstract Purpose As Rosa damascena essential oils (RDEOs) have antioxidant, antibacterial, antiviral, and insecticidal activity, they could therefore be useful in the treatment of breast cancer. In the current study, an attempt was made to incorporate RDEO in a lipid-based drug delivery system, namely, nanostructured lipid carrier (NLC) to boost its anticancer effect compared to cisplatin. Methods Gas chromatography (GC) identified the chemical compositions of RDEO. RDEO-NLCs were prepared using the probe ultrasonication method. The obtained nanoparticles were characterized in terms of particle size, polydispersity index, and zeta potential by dynamic light scattering. The encapsulation efficiency of the formulations and their loading capacity were also determined, and transmission electron microscopy (TEM) was employed to evaluate the morphology of the optimal formulation (quoted as RDEO-NLC2). The anticancer effect of RDEO-NLC2 on MDA-MB-231 cells and apoptosis were assessed using MTT and in vitro cellular assays respectively. Results TEM result revealed a distinct spherical shape for RDEO-NLC2, with an average particle size of 78.39 ± 1.5 nm obtained by Zetasizer. The results also showed that the obtained particles had a negative surface charge (− 31.0 mV) with a polydispersity index of 0.28 ± 0.01. The chemotherapy drug cisplatin showed more cytotoxicity than RDEO-NLC2 against cancer cells. Cellular data demonstrated that RDEO-NLC2 like cisplatin can decline the viability of MDA-MB-231 cells through apoptosis compared to cells treated with the placebo and free RDEO. Conclusion RDEO-NLC2 has the ability to stimulate apoptosis in the human BC cell line MDA-MN-231; hence, it can be beneficial in the treatment of patients suffering from breast cancer.

Treatment modalities vary based on symptomatology and may range from physiotherapy to pharmacologic intervention and surgical intervention. Despite the current therapeutic strategies, outcomes remain suboptimal. In light of limited data regarding the therapeutic effects of oil-based massages on neonates with CP, this study aimed to investigate the potential neurological benefits of incorporating herbal oils into massage treatments for these infants. In this investigation, we conducted a thorough exploration of the medicinal herbs described in the paralysis section of medical and pharmaceutical sources in Persian medicine. Subsequently, we conducted an extensive literature review on the neurological effects of oils or essential oils derived from these herbs. Our search was conducted up to 2023 using pertinent keywords such as Pimpinella anisum L., anise, aniseed, Foeniculum vulgare Miller, fennel, Carum carvi L., caraway, Piper nigrum L., pepper, Cinnamomum zeylanicum, cinnamon, Nigella sativa L., black seed, Vitis vinifera L., grape seed, Olea europaea L., olive, Rosa x damascena Herrm., and rose flower. We specifically focused on studies related to neuroprotection, neurology, massage, and cerebral palsy, and obtained relevant information from data sources such as PubMed, Scopus, and Google Scholar. Our investigation revealed that massage therapy has an impact on CP and that herbal oils possess neurological properties, such as anticonvulsant and neuroprotective effects, as well as enhancements in behavior, memory, learning, and cerebral function. Based on the advantageous mechanisms of action of herbal oils, we postulate that massage therapy utilizing herbal oils may offer a promising complementary approach in the management of newborns with CP. We recommend further experimental and clinical studies to establish their effectiveness.

Abstract:

AbstractTo develop an environmentally acceptable corrosion inhibitor Rosa damascene extract (RD) served as the main ingredient in H2SO4 pickling processes. X‐ray photoelectron spectroscopy (XPS), Fourier‐transform infrared spectroscopy (FT‐IR), technique of electrochemical impedance spectroscopy (EIS), polarization (PP) curves, and tests of weight loss (WL) have all been utilized to examine the inhibitory behavior of Rosa damascene on C‐steel corrosion in 1 M H2SO4 environment. The results show that the extract effectively inhibited the Zn′ corrosion in 1 M H2SO4. The inhibition was more effective at higher concentrations and temperatures. The inhibitory efficiency increased to 93.5% at a higher applied temperature (45°C) and higher Rosa damascene concentration (300 ppm). However, utilizing the weight loss method at potassium iodide addition, the inhibitory effectiveness of 300 ppm of Rosa damascene was synergistically increased from 75.0% to 96.1% at 25°C. Temkin isotherm was congruent with the adsorption process that produced the inhibitory impact on the C‐steel. The chemical adhesion of the Rosa damascene extract to the surface of the C‐steel was determined by the free energy of adsorption (ΔGoads = 40.5 kJ/mol.). In H2SO4 solution, corrosion of C‐steel may be prevented by the powerful inhibitor Rosa damascene extract.

Abstract:

AbstractThe progressive increase in infections caused by multidrug‐resistant (MDR) Gram‐negative bacteria and the emergence of resistance to last‐resort antimicrobial drugs in recent years necessitate the development of new therapeutic strategies. This study was conducted to obtain nanostructured antimicrobials by conjugating colistin (COL) and meropenem (MEM) antibiotics with biosynthesized silver nanoparticles (bio‐AgNPs) via the green synthesis method using Rosa damascena extract, and to investigate the antibacterial and antibiofilm activity of these nanostructures against Escherichia coli and Klebsiella pneumoniae strains. Ultraviolet–visible spectrophotometry, high‐resolution‐transmission electron microscopy, atomic force microscopy, X‐ray diffraction, and Fourier transform‐infrared spectroscopy analyses were performed to determine the physical and chemical properties of synthesized bio‐AgNPs, COL@bio‐AgNPs, MEM@bio‐AgNPs, and COL&MEM@bio‐AgNPs. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration of nanoparticles were determined on standard and MDR clinical strains. The antibiofilm efficacy and cytotoxic effect of nanoparticles were evaluated by the crystal violet dye method and 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyl tetrazolium bromide dye method, respectively. The characterization analyses demonstrated that the synthesized nanoparticles had crystal structure and spherical morphology (5.6–30.2 nm in size). Antibiotic conjugated nanoparticles exhibited better antimicrobial activity and lower MIC values (0.125–4 µg/mL) on the tested strains compared to free antibiotics, and MIC values were decreased up to 1024‐fold (p < 0.05). Antibiotic conjugated nanoparticles were found to be more effective in biofilm eradication than free antibiotics and bio‐AgNPs and had a less inhibitory effect on peripheral blood mononuclear cell viability. The findings revealed that antibiotic‐conjugated nanoparticles have the potential to be used as an effective antimicrobial drug against MDR E. coli and K. pneumoniae strains.
