A Battery of Simple Bioassays for Domestic and Industrial Wastewater Treatment Plants in Konya, Turkey

Wastewater ingredients present risks to the environment and can cause health problems. The aim of this study was to identify the toxicological effects of influent and effluent wastewater from Konya Urban Wastewater Treatment Plant (KU WWTP) and Konya Organized Industrial Zone Wastewater Treatment Plant (KOI WWTP). Three different trophic level toxicity tests were conducted to determine the possible harmful effects of wastewater on the environment. The base toxic unit values of the Lepidium sativum toxicity test for the inlet and outlet samples of KU WWTP were found to be 1.43 and 1.10, respectively. Both values classified the analyzed wastewater into the “toxic” category. Wastewater entering the KU wastewater treatment facility was classified as “toxic” for the presence of toxic substances according to the Vibrio fischeri toxicity testing. Influent samples from the KOI wastewater treatment plant were classified as “toxic” with the Vibrio fischeri toxicity test. In addition, based on the fish bioassay value (TDF), wastewater from the KOI treatment facility was also classified as “toxic”. It was concluded that increased chemical oxygen demand and concentrations of total nitrogen and phosphorus and of certain heavy metals above the limits played a decisive role in classifying the samples as “toxic”. The results of this study suggest that all three tests have the potential to assess wastewater toxicity and that changes in wastewater properties may result in differences in test sensitivity.

Increased Free Radical Scavenging Activity and Consumer Preference in Garden Cress (Lepidium sativum L.) Subjected to Water Stress

Although the Garden Cress is known to grow in a wide range of climatic conditions, there are limited studies on how water stress can affect their morphological, biochemical and sensory characteristics. In this research, these characteristics in the Garden Cress leaves were measured in response to water stress. In this study two different irrigation restrictions (50% and 25% irrigation) were applied against the control plants (100% irrigation) in four replications. As a result, the amount of proline was determined as 5.98 mg-1100g in control plants, and as 36.72 mg-1100g in 25% irrigated plants. While total phenolic compounds and total flavonoids varied from 61.26 to 68.04 mg of GA-1100gFW and 8.35 to 11.70 mg QE-1100gFW, respectively, the differences were statistically insignificant. The increase of DPPH free radical scavenging activity in line with increased water stress, however, was found to be statistically significant. In conclusion, the 50% water stress applied Garden Cress leaves were found to be most preferred by the consumers in terms of flavor and had higher radical scavenging activity than control plants. Irrigation management practices, therefore, could consider limited water use with Garden Cress production under possible negative effects of climate change on water resources.

Development and Evaluation of Emulgel Formulation of Diclofenac Sodium utilizing Lipidium sativum as a Gelling Agent

Emulgels have gained recognition as an effective method for delivering non-polar drugs. The primary goal of our current research is to investigate the potential of Lepidium sativum seed mucilage as a gelling agent in this context. To enhance drug penetration, we have incorporated clove oil, oleic acid, and methyl salicylate. An emulsion was formulated and subsequently integrated into the gel base. Our research encompassed a series of studies, including rheological assessments, spreading coefficient evaluations, investigations into skin irritancy, and other relevant tests. Furthermore, we conducted drug content analysis, in-vitro release and permeation studies, and stability assessments. In our in-vitro investigations, it was observed that formulation E6 exhibited the highest drug release within a span of 180 minutes. Comparative analyses were conducted, pitting formulations E4, E5, and E6 against a commercially available emulgel preparation. As a result of our findings, it is evident that an emulgel employing L. sativum mucilage can effectively function as a gelling agent in a topical drug delivery system.

Allelochemical root-growth inhibitors in low-molecular-weight cress-seed exudate.

Cress seeds release allelochemicals that over-stimulate the elongation of hypocotyls of neighbouring (potentially competing) seedlings and inhibit their root growth. The hypocotyl promoter is potassium, but the root inhibitor was unidentified; its nature is investigated here. Low-molecular-weight cress-seed exudate (LCSE) from imbibed Lepidium sativum seeds was fractionated by phase partitioning, paper chromatography, high-voltage electrophoresis and gel-permeation chromatography (on Bio-Gel P-2). Fractions, compared with pure potassium salts, were bioassayed for effects on Amaranthus caudatus seedling growth in the dark for 4 days. The LCSE robustly promoted amaranth hypocotyl elongation and inhibited root growth. The hypocotyl inhibitor was non-volatile, hot acid stable, hydrophilic and resistant to incineration, as expected for K+. The root inhibitor(s) had similar properties but were organic (activity lost on incineration). The root inhibitor(s) remained in the aqueous phase (at pH 2.0, 6.5 and 9.0) when partitioned against butan-1-ol or toluene, and were thus hydrophilic. Activity was diminished after electrophoresis, but the remaining root inhibitors were neutral. They became undetectable after paper chromatography; therefore, they probably comprised multiple compounds, which separated from each other, in part, during fractionation. On gel-permeation chromatography, the root inhibitor co-eluted with hexoses. Cress-seed allelochemicals inhibiting root growth are different from the agent (K+) that over-stimulates hypocotyl elongation and the former probably comprise a mixture of small, non-volatile, hydrophilic, organic substances. Abundant components identified chromatographically and by electrophoresis in cress-seed exudate fitting this description include glucose, fructose, sucrose and galacturonic acid. However, none of these sugars co-chromatographed and co-electrophoresed with the root-inhibitory principle of LCSE, and none of them (in pure form at naturally occurring concentrations) inhibited root growth. We conclude that the root-inhibiting allelochemicals of cress-seed exudate remain unidentified.

Exploring the interplay of phytohormones and polyamines in drought-stressed Cress (<i>Lepidium sativum</i> L.) leaves

The study investigated prolonged drought stress effects on phytohormone and polyamine levels in cress (Lepidium sativum L.) leaves, elucidating plant responses to harsh environments. Phytohormones, 12-oxophytodienoic acid (OPDA), Jasmonic acid (JA), Jasmonyl-Isoleucine (JA-Ile), Abscisic acid (ABA), and salicylic acid (SA) increased, especially ABA that rose consistently. Indole-3-acetic acid (IAA) responded akin to ABA and SA. Cytokinins such as zeatin (ZT) and isopentenyl adenine (iP) diversified drought tolerance, ZT fell sharply, and iP remained stable. Gibberellic acid (GA3) declined, while brassinolide (BL) surged with prolonged drought. Polyamines reduced, indicating sensitivity to severe drought. Findings uncovered intricate regulatory mechanisms for plant adaptation to water scarcity. Interaction of OPDA, JA, JA-Ile, ABA, SA, IAA, ZT, iP, GA3, BL, and polyamines contributes to drought coping and physiological balance. Insights into cress leaf response and drought tolerance mechanisms contribute significantly to plant drought adaptation understanding.

The utilisation of thermally treated poultry farm waste for energy recovery and soil application

The thermal treatment was analysed of poultry farm waste, excrement and litter, and their mixture. Two thermal treatment methods were chosen: Torrefaction at 300 °C and hydrothermal carbonisation (HTC) at 250 °C. The characterisation of raw materials and solid products was performed by proximate and ultimate analysis, and analysis of the high heating value. Thermogravimetric analysis (TGA) was performed of the combustion of raw materials and solid products in an air atmosphere. The kinetic and thermodynamic parameters were determined according to the Flynn–Wall–Ozawa (FWO) kinetic model. The contents of total organic carbon, chemical oxygen demand, total nitrogen and total phosphorus, as well as the content of total phenols, were determined in the process fluids. In addition, a germination test was performed with garden cress.The results show that the torrefied biomass had a higher carbon (C) content and a higher calorific value than raw biomass. The FWO kinetic model proved to be suitable for describing the kinetic of combustion of the tested samples' high fitting coefficients. The Eα for torrefied litter, excrement and their mixture ranged between 129 and 338, 108–550 and 136–489 kJ/mol, while for the HTC-treated samples generally lower Eα values were measured, 187–364, 121–229 and 126–428 kJ/mol, respectively. Germination tests with garden cress and analysis of nutrients showed that the tested products of torrefaction and HTC have a perspective for agricultural use at a sample concentration of up to 10 wt% in the substrate.

Hatay İlinde Yetiştirilen Farklı Brassica türlerine ait Minör Sebzelerde Fungal ve Bakteriyel Hastalık Etmenlerinin Belirlenmesi

The Brassicaceae family, commonly known as the Cruciferae or mustard family, encompasses plant species of global economic significance, including oilseed crops, vegetables, as well as condiment purposes. Hatay Province is among the significant regions in Turkey where Brassicaceae family vegetables are cultivated. This study aimed to identify the causative agents of diseases affecting minor Brassica vegetables including cabbage (red and white varieties), broccoli, cauliflower, garden cress, rocket, and radish in the districts of Hatay Province where vegetable cultivation took place during the 2020-2021 growing seasons. Isolations from suspicious cabbage, broccoli, cauliflower, and radish plants exhibiting disease symptoms in the surveyed areas revealed the presence of various fungal disease agents, including Rhizoctonia solani, Sclerotinia sclerotiorum, Fusarium solani, Fusarium oxysporum, Fusarium equiseti, Alternaria alternata, Botrytis cinerea, and Stemphylum sp. Furthermore, obligate parasitic oomycete pathogens such as Albugo lepidii, Albugo candida, and Perofascia lepidii were detected with varying prevalence and incidence rates on leaves and stems of water cress, rocket, and radish plants.
 In addition to fungal pathogens, primary bacterial pathogens, including Xanthomonas campestris pv. campestris, Pectobacterium carotovorum subsp. carotovorum, Pectobacterium parmentieri, Pseudomonas corrugata, and Pseudomonas cichorii, were identified through morphological, biochemical, pathogenicity tests, and MALDI-TOF analyses. Pantoea agglomerans, Pseudomonas marginalis, Pseudomonas fluorescens, Enterobacter cloacae, and Bacillus pumilus were also identified as opportunistic soft rot bacterial pathogens.
 To the best of our knowledge, this is the first report of F. solani, F. oxysporum, F. equiseti, A. alternata, B. cinerea, Stemphylum sp., P. parmentieri, P. corrugata, and P. cichorii as primary bacterial pathogens, P. agglomerans, P. marginalis, P. fluorescens, E. cloacae, and B. pumilus as opportunistic secondary soft rot bacterial disease agent affecting different minor Brassica vegetables, such as cabbage (red and white varieties), broccoli, cauliflower, radish, rocket, and garden cress, grown in Turkey.

Phytochemical study on the essential oils of Callitris glaucophylla Joy Thomps. & L.A.S. Johnson, and assessment of their antioxidant, anti-enzymatic and allelopathic effects

Callitris glaucophylla Joy Thomps. & L.A.S. Johnson is a coniferous forest species of the Cupressaceae family native to Australia. This species is rich in essential oils (EOs) but few studies about variability and biological activity of these EOs are available in the literature. The purpose of this study was to evaluate the variability of production of C. glaucophylla EOs in relation to the different plant parts (needles, cones and stems) and to investigate their antioxidant, anti-enzymatic and herbicidal properties. EOs were obtained by hydro distillation and analyzed by GC and GC-MS. The antioxidant potential of EOs was assessed by ABTS, FRAP and DPPH assays, their phytotoxic activities were evaluated against germination and shoots and radical growth of Sinapis arvensis, Trifolium campestre, Lepidium sativum and Lolium rigidum. The EOs were evaluated for their possible anti-enzymatic effects with spectrophotometric assay. EOs resulted rich in monoterpenes hydrocarbons (61.04–77.82 %) and oxygenated monoterpenes (19.52–25.26 %). The main compounds were α-pinene as major compound in all plant parts (36.99–59.84 %), 1,8-cineole (19.88 % in stems) and limonene (18.94 % in needles). Herbicidal assays showed that all EOs have remarkable and significant phytotoxicity towards germination, roots, and aerial parts growth of the tested plants, depending on the EO, the doses and tested species. The EOs showed significant free radical scavenging potential and resulted more active against cholinesterases than α-glucosidase and α-amylase. The data obtained constitute an important contribution in selecting and valorizing appropriate forestry tree biomass as sources of antioxidant and phytotoxic molecules for sustainable application in food preservation and weeds control. The activities against the tested enzymes confirmed a possible use of these EOs as natural pesticides.

Ecotoxicological assessment of waste-derived organic fertilizers and long-term monitoring of fertilized soils using a multi-matrix and multi-species approach

The present study investigates the ecotoxicity of 7 biofertilizers, including biowaste-derived organic matrices. Real-field tests were conducted to assess the impacts of soil fertilization with sewage sludge digestate from high-solid thermophilic anaerobic digestion (HSTAD) compared to those obtained on non-amended and urea-fertilized soils. The physical-chemical and ecotoxic impact of HSTAD digestate on soil was monitored for 12 months, at 5 time points and 2 soil depths, on a maize field divided in 3 portions (non-treated, fertilized with urea, amended with digestate). The chemical and physical characteristics of the soil were previously analyzed for 3 years to provide a long-term outlook of the impacts of biofertilizer application. Seven bioindicators were utilized for direct (on whole soil) and indirect (on soil elutriates) ecotoxicological tests on fertilizers and amended soils, including plant seeds (Lepidium sativum, Sorghum saccharatum, and Sinapsis alba), the aquatic organism Daphnia magna, the alga Raphidocelis subcapitata, the luminescent bacterium Aliivibrio fischeri, and the Nematode Caenorhabditis elegans. No serious negative effects on soil fertilized with HSTAD digestate were evidenced. Conversely, bioassays rather showed positive effects, encouraging the utilization of HSTAD digestate in agriculture, considering the proper concentrations of use. The obtained data were interpolated and a test battery integrated index was generated, confirming the absence of ecotoxicological risk for the soils amended with the applied fertilizers. The long-term evolution of the physical-chemical soil characteristics (including the concentrations of potential contaminants) was similar for both HSTAD digestate and urea application as well as for non-fertilized soil, indicating no negative effects due to digestate application on land. On the contrary, digestate application improved the content of stabilized organic matter and nutrients in soil. This study proposes a more correct approach to ecotoxicity assessment of fertilized soils for biofertilizer evaluation and demonstrates the long-term safe application of HSTAD digestate on agricultural soil.

There was a variation effect in the antifungal activity of the methanol seed extract against Aspergillus niger the results established the methanol seed extract appeared the differences in their antioxidant activity and diverse variety. It was variation in the activity in relation to concentration (activity decrease with decrease extract concentration), Seed extract showed antioxidant activity in this study, the anti-oxidation effect of the L. sativum seeds extract by methanol, which give the highest percentages at concentration 1mg, reaching 91.419 and the lowest value at concentration 0.12, which amounted to 81.308. The present study deals with, antimicrobial properties and Anti-oxidant activity constituents of Gc seeds.

Growth and Development of Leaf Vegetable Crops under Conditions of the Phytotechnical Complex in Antarctica

Ensuring the technical and technological possibility of regularly obtaining fresh, high-quality plant production in Antarctic stations is an urgent task of our time. This work is devoted to studying the growth and development of leaf vegetable crops and the main quality indicators of their edible parts when grown in the phytotechnical complex greenhouses at the “Vostok” Antarctic station and at the agrobiopolygon of the Agrophysical Research Institute (AFI). The plants, belonging to 13 varieties of 9 types of leaf vegetable crops (arugula, garden cress, cabbage, mustard, leaf radish, leaf lettuce, amaranth, dill, parsley leaf), were studied during five growing seasons at the “Vostok” station and at the AFI agrobiopolygon under controlled conditions (control). The experimental data obtained demonstrate the high productivity of the phytotechnical complex for most of the investigated crops per unit of useful area, with lower costs of electricity and water consumption per unit of production compared with a number of greenhouses at foreign Antarctic stations and greenhouse complexes with controlled conditions located on other continents. Lettuce crops were the most adapted to the growing conditions at the Antarctic station “Vostok”. They did not differ in their evaluated characteristics from the control. All other investigated crops, while not differing in their development rate and quality, had statistically significant (16–61%) decreases in their yield per 1 m2 per year. This may demonstrate the difference in the “genotype–environment” interaction in plants grown at the Antarctic station and AFI agrobiopolygon, probably due to the different barometric pressure and partial pressure of oxygen at the two locations. The positive psychological effects of the greenhouses were identified along with nutritional and other qualities of the plants.

CHARACTERIZATION OF SYNTHESIZED SILVER NANOPARTICLES USING LEPIDIUM SATIVUM PLANT

The biosynthesis of Silver Nanoparticles (Ag NPs) was achieved through the utilization of an extract derived from the plant Lepidium Sativum, commonly referred to as Garden cress. The current study was undertaken to examine the impacts of different concentrations of silver nitrate (AgNO3) (0.1, 0.15, 0.2, 0.25, and 0.3) on the properties of silver nanoparticles. A range of analytical techniques were utilized to examine the characteristics of the nanoparticles, encompassing energy dispersive X-ray (EDX), field emission scanning electron microscopy (FESEM), UV-visible spectrophotometry (UV-Vis), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). The findings demonstrated and suggested that Lepidium Sativum represents a viable choice for the environmentally friendly production of silver nanoparticles. The UV-Vis spectra of the studied silver nanoparticles (Ag NPs) exhibited a significant level of absorption within the wavelength range of 430-460 nm. The most intense absorption peak, observed at 453 nm, was associated with a concentration of 0.25 mol. The examination of the Field Emission Scanning Electron Microscope (FESEM) images has revealed that the concentration of the solution has a substantial impact on the size, morphology, shape, and orientation of the silver nanoparticles (Ag NPs). The Ag NPs exhibit a mostly spherical and semi-spherical form, with an average particle size ranging from 65 to 80 nm. Additionally, the X-ray diffraction (XRD) analysis revealed that the silver nanoparticles (Ag NPs) synthesized exhibit a high level of purity, consisting solely of silver atoms arranged in a face-centered cubic crystalline lattice structure. The particle size, as determined from the (111) peak, falls within the range of 25.31-67.28 nm. The EDX spectrum analysis indicated that the primary chemical constituent present in the samples was silver (Ag). The silver nanoparticles (Ag NPs) produced at different concentrations exhibited a distinct peak in the UV-Vis spectrum, demonstrating significant absorbance above 400 nm in the visible region and minimal absorption in the UV range. The measured energy band gap (Eg) ranged from 2.05 to 2.3 eV. In addition, the Fourier Transform Infrared (FTIR) spectra of silver nanoparticles (Ag NPs) at different concentrations did not exhibit any discernible peak throughout the monitored range. This observation implies that the silver nanoparticles that were produced using cress plant extract had a high level of purity.

Can an Alginate-based Wound Dressing Modified with Garden Cress Substitute for COE-PAK as a Wound Dressing? An In Vitro Study.

The aim of the current study was to prepare a natural oral wound dressing from alginate modified with garden cress (GC), a rich source of antibacterial phytochemical compounds essential for wound healing. Sodium alginate (SA) dressing (negative control group), was prepared and modified with GC seeds extracts (25 µg/mL and 50 µg/mL) as the intervention groups, and COE-PAK was the positive control group. Cytotoxicity was measured using WST-1 assay (n = 15) after 24 and 48 hours. The in vitro wound healing assay (n = 15) was assessed in terms of wound width, and cell migration rate (0, 24, 48, and 72 hours). Agar diffusion test was performed to investigate the antibacterial action (n = 15) of the groups against Streptococcus mutans and Lactobacillus casei strains. Results were significant at p ≤ 0.05. There was no statistically significant difference in cytotoxicity in all groups (p = 0.24 at 24 hours and 0.1 at 48 hours). Garden cress-containing groups revealed the lowest mean value of wound width (0.27 mm ± 0.01 and 0.23 mm ± 0.01 for 25 µg/mL and 50 µg/mL, respectively at 48 hours) and the highest mean value of cell migration rate (0.013 mm/hour ± 0.004 and 0.014 mm/hour ± 0.004 for 25 µg/mL and 50 µg/mL, respectively at 48 hours), in addition to the highest antibacterial action (1.49 mm ± 0.05 and 2.14 mm ± 0.09 for 25 µg/mL and 50 µg/mL, respectively against S. mutans, 1.43 mm ± 0.07 and 2.55 mm ± 0.09 for 25 µg/mL and 50 µg/mL, respectively against L. casei). Alginate wound dressing modified with GC extract could be considered a promising wound dressing material in terms of wound healing and antibacterial action. Ready-to-use alginate-based wound dressing modified with GC extract may represent a promising natural alternative to the most commonly used oral wound dressing (COE-PAK).

Antimicrobial and antioxidant effects of an edible coating of Lepidium sativum seed mucilage and Satureja hortensis L. essential oil in Uncooked lamb meat

The current research aimed to fabricate an active edible coating, Lepidium sativum seeds mucilage (LSSM) loaded with Satureja hortensis essential oil (SHEO) (0, 0.5, 1, and 1.5 % (w/w)) for further extension of the shelf life of refrigerated lamb meat during storage for 18 days at (4 °C). The control and the coated lamb meat samples were continually analyzed for microbiological (total count, psychrotrophic count, yeast and mold), chemical (pH, moisture content, PV, and TBA), and sensory characteristics. Consistent with the microbiological analysis, the LSSM incorporated with 1, and 1.5% SHEO caused a significant shelf-life extension of the lamb meat by 15 and 18 days, respectively. These results suggested that (LSSM+1.5%S) sufficiently hindered the overall bacterial growth in the lamb meat sample since the shelf life in this treatment was 12 days more in comparison to the control. Hence, LSSM containing SHEO is very useful as an active packaging in order to preserve the quality and to prolong the lamb meat shelf life at 4 °C.

A review on the fate of micro and nano plastics (MNPs) and their implication in regulating nutrient cycling in constructed wetland systems

This review discusses the micro-nano plastics (MNPs) and their interaction with physical, chemical and biological processes in a constructed wetland (CW) system that is typically used as a nature-based tertiary wastewater treatment for municipal as well as industrial applications. Individual components of the CW system such as substrate, microorganisms and plants were considered to assess how MNPs influence the CW processes. One of the main functions of a CW system is removal of nutrients like nitrogen (N) and phosphorus (P) and here we highlight the pathways through which the MNPs influence CW's efficacy of nutrient removal. The presence of morphologically (size and shape) and chemically different MNPs influence the growth rate of microorganisms important in N and P cycling, invertebrates, decomposers, and the plants which affect the overall efficiency of a CW treatment system. Certain plant species take up the MNPs, and some toxicity has been observed. This review focuses on two significant aspects: (1) the presence of MNPs in a significant concentration affects the efficiency of N and P removal, and (2) the removal of MNPs. Because MNPs reduce the enzyme activities in abundance and overproduction of ROS oxidizes the enzyme active sites, resulting in the depletion of proteins, ultimately inhibiting nitrogen and phosphorus removal within the substrate layer. The review found that the majority of the studies used sand-activated carbon (SAC), granular-activated carbon (GAC), rice straw, granular limestone, and calcium carbonate, as a substrate for CW treatment systems. Common plant species used in the CW include Phragmites, Arabidopsis thaliana, Lepidium sativum, Thalia dealbata, and Canna indica, which were also found to be dominant in the uptake of the MNPs in the CWs. The MNPs were found to affect earthworms such as Eisenia fetida, Caenorhabditis elegans, and, Enchytraeus crypticus, whereas Metaphire vulgaris were found unaffected. Though various mechanisms take place during the removal process, adsorption and uptake mechanism effectively emphasize the removal of MNPs and nitrogen and phosphorus in CW. The MNPs characteristics (type, size, and concentration) play a crucial role in the removal efficiency of nano-plastics (NPs) and micro-plastics (MPs). The enhanced removal efficiency of NPs compared to MPs can be attributed to their smaller size, resulting in a faster reaction rate. However, NPs dose variation showed fluctuating removal efficiency, whereas MPs dose increment reduces removal efficiency. MP and NPs dose variation also affected toxicity to plants and earthworms as observed from data. Understanding the fate and removal of microplastics in wetland systems will help determine the reuse potential of wastewater and restrict the release of microplastics. This study provides information on various aspects and highlights future gaps and needs for MNP fate study in CW systems.

Quantification of nanoplastic uptake and distribution in the root, stem and leaves of the edible herb Lepidum sativum

This study confirms the uptake, translocation and bioaccumulation of 100 nm polystyrene nanoplastics in the root, stem and leaves of the plant Lepidum sativum at exposure concentrations ranging from environmentally realistic 10 μg/L up to a high of 100 mg/L. Accumulation in plant tissues was characterised by aggregation in the intercellular spaces and heterogeneous distribution. Nanoplastic presence was confirmed in the root tips, root surface and stele, lateral roots, root hairs, stem vascular bundles, leaf veins and mesophyll, as well as leaf epidermis including stomatal sites. Quantification results show that majority of the particles were retained in the root and accumulation in stem and leaves was only 13 to 18 % of the median value in roots. There was a reduction of 38.89 ± 9.62 % in the germination rate, 55 % in plant fresh weight, as well as in root weight (> 80 %), root length (> 60 %), shoot weight (51 to 78 %) and number of lateral roots (> 28 %) at exposure concentrations at and above 50 mg/L. However, lower, environmentally probable exposure concentrations did not affect the plant health significantly. Our results highlight the urgent need for further exploration of this issue from the point of view of food safety and security. Statement of environmental implicationMicro and nanoplastics have been reported in agricultural environments across the globe and reports regarding their hazardous effects over agricultural and plant health call for an urgent exploration of this issue. This work demonstrates the uptake, bioaccumulation and distribution of nanoplastics in an edible plant at an environmentally realistic concentration and raises serious concerns regarding the possible implications for food safety and security. It presents a novel approach which addresses the quantification of nanoplastic accumulation in plant tissues and helps identify the mechanism and trends behind this phenomenon which has been a challenge up until now.

Development and Evaluation of Pullulan Based Mouth Dissolving Film of Furosemide

Mouth dissolving oral film is an innovative approach as Oromucosal route for systemic delivery of therapeutically/medicinally active drug substance. As we know Furosemide belongs class IV in BCS classification of drug, having low solubility and permeability due to the presence of strong inter and intramolecular bond. Due to low aqeous solubility, it exhibits low oral bioavailability. Here we are preparing mouth dissolving film of furosemide to increase its solubility, which ultimately will enhance its bioavailability. By this way, we will achieve more rapid drug absorption, desired pharmacological effect with quick onset of action by avoiding degradation in GIT and first pass metabolism. This system will provide maximum therapeutic efficacy and maximum stability by reducing the frequency of dosage and as well as improve patient compliance. The present research aimed to prepare pullulan based mouth dissolving oral films of furosemide used in treatment and control of hypertension. Pullulan was selected as film former exhibit better moisture retention, oxygen barrier and uniform film forming properties. Due to the hydrophilic nature of pullulan, it provides quick dissolution. By considering above points, the film was prepared through solvent casting method by pullulan as film-forming polymer, glycerol as plasticizer and lepidium sativum mucilage as a natural disintegrant known as Asaliyo. Disintegration time, drug release, moisture loss and folding endurance of film were evaluated. Promising batch F6 exhibited better drug dissolution 98.75±0.09% within 8±0.4 minutes than the other films. The disintegration time for batch F6 was 23±5 sec. It is evident from the above results that it is an innovative dosage form to improve the drug delivery, onset of action as well as improve patient compliance.

Impact of Pretreatment of Garden Cress Seed on Rheological Properties for Bread Dough

The rheological properties of bread dough made with various ratios of garden cress seed (GCS) and refined wheat flour were investigated. The Brabender Farinograph E, Extensograph E and Amylograph E were used to determine rheological properties such as water absorption, development time, extensibility, proving time, tolerance index, and gelatinization. Refined wheat flour proportion was kept constant, whereas that of GCS had prior treatment of germinated (G), grounded/untreated (U), and roasted (R) by 2%, 4%, and 6%, respectively. The values for water absorption (500 B.U.) ranged from 66.4% to 71.6%, whereas the values for water absorption (14.0%) ranged from 63.3% to 70.7%. The development times for the flour blend formulations ranged from 5.2 to 6.5 min for samples T0, T10G to T18R. The tolerance index improved from sample T0, T10G to T18R with the inclusion of GCS flour, i.e. from 73 to 113 BU. Extensograph values were taken at curves corresponding to proving periods of 30, 60, and 90 minutes. The energy area declined and the extension resistance increased as the proving time increased. All of the sample ratio values were between 1.5 and 5. The dough obtained from mixes of roasted GCS and untreated i.e. powered GCS with refined wheat flour enhanced the amylographic parameters of the amylogram peak maximum, temperature, and gel viscosity. T16R attained the highest point at 59.5ºC, followed by T15U6, T14U4, and T13U2 at 58.4, 57.1, and 55.9 ºC, respectively. The results demonstrated that combining GCS flour improved the rheological properties and quality of the flour dough. This dough can be used to manufacture bread and other bakery goods because to its high nutritional value and beneficial benefits on human health.
