Given the risk of Candida albicans overgrowth in gut, novel complementary therapies should be developed to reduce fungal dominancy. This study highlights antifungal characteristics a Bacillus subtilis-derived secondary metabolite, surfactin with high potential against C. albicans. Surfactin inhibited growth following 1-hour exposure, addition reduced adhesion and morphogenesis. Specifically, did not affect level reactive oxygen species but increased glutathione. Surprisingly, ethanol...
Electrospinning has recently been recognized as a potential method for use in biomedical applications such nanofiber-based drug delivery or tissue engineering scaffolds.

Abstract The assessment of heavy metal pollution in leaves and soils is essential environmental health monitoring. We assessed the effect anthropogenic activities along an industrial–urban–rural gradient roadside soil tree Bangladesh based on their concentration. concentrations Pb, Cr, Ni, Cd were analysed Ficus benghalensis , Swietenia macrophylla Polyalthia longifolia topsoil samples using ICP-OES. used indices to quantify impact contaminants ecosystems. Our findings indicated that there...
Increasing pollution of aquatic ecosystems due to anthropogenic activities underscores the urgent need for effective water quality monitoring. This study evaluates use fish scales from chub (Squalius cephalus) and nase (Chondrostoma nasus) as non-invasive bioindicators trace macroelement in Maros/Mureș River. We conducted qualitative quantitative elemental analyses using X-ray fluorescence (XRF) inductively coupled plasma optical emission spectrometry (ICP-OES). Scanning electron microscopy...
Fish scales absorb different elements into the calcified matrix from surrounding waters as well foods consumed. Scales microchemistry is drawing rising attention for its applicability in a wide range of fields, including environmental and ecological studies. The article represents an elemental analysis five commercially important coastal fishes: Tenualosa ilisha, Sillaginopsis panijus, Lates calcarifer, Otolithoides pama, Rhinomugil corsula . concentrations essential trace were measured...
Abstract Metal contamination poses a high risk for organisms, especially those with extensive food chain relevancy. Thus, elevated concentration of metals is considered major cause concern in crops. This study aimed to evaluate the short-term responses sorghum and Sudan grass different Cd/Zn doses complex germination test by assessing growth parameters, tissue metal concentrations, interaction accountant ecophysiological elemental alterations. To do so, radicle hypocotyl length were...
Candida auris is a dangerous fungal pathogen that causes outbreaks in health care facilities, with infections associated high mortality rate. As conventional antifungal drugs have limited effects against the majority of clinical isolates, new and innovative therapies are urgently needed.
Several studies show that the elemental content of honey entirely depends on botanical and geographical origin, but information is incomplete regarding its time-dependent composition changes. Twenty-six acacia three samples with unknown origin were collected between 1958 2018 analysed for by Microwave Plasma Atomic Emission Spectrometry (MP-AES). The analysis was coupled independent dating method Accelerator Mass (AMS) to confirm calendar age test possibility radiocarbon based bee products,...
The biggest threat to beekeeping is varroosis caused by the mite Varroa destructor. Chemicals available treat this fatal disease may present problems of resistance or inconsistent efficacy. Recently, lithium chloride has appeared as a potential alternative. To date, amount residue treatments leave in honeybee products poorly understood. Honeybees were fed with 25 mM lithiated sugar syrup, which was used earlier studies. accumulation and elimination monitored bees their for 22 days. Lithium...
Septic tanks without proper construction and insulation entail a significant risk to the environment. In this study, environmental impacts of permeably designed septic tank on shallow groundwater contamination are investigated, changes in water quality period after its elimination 2014 assessed. For purpose evaluating pollution level site, 10 monitoring wells were installed around 2012 long-term was carried out. Analytical measurements revealed operational tank. Extremely high concentrations...
Disposal sites without adequate engineering controls pose a significant risk to the environment. In present study, environmental hazards of an abandoned and unrecultivated liquid waste disposal are investigated with special focus on soil shallow groundwater contamination. After period operation from 1994 2010, when wastewater collection municipality was regulated, site subsequently decommissioned further action. Eight monitoring wells have been established in basins surrounding area...
In this study, growth and ionomic responses of three duckweed species were analyzed, namely Lemna minor, Landoltia punctata, Spirodela polyrhiza, exposed for short-term periods to hexavalent chromium or nickel under laboratory conditions. It was found that different had distinct patterns can change considerably due metal treatments. The results also show that, because the stress-induced increase in leaf mass-to-area ratio, studied showed order uptake efficiency if plant area used as unit...
The applicability of capillary electrophoresis (CE) with light-emitting diode-induced fluorescence detection (LEDIF) for the separation sugars in honey samples was studied. An amount 25 mM ammonium acetate (pH 4.5) 0.3% polyethylene oxide (PEO) found to be optimal efficient carbohydrates. 8-aminopyrene-1,3,6-trisulfonic acid (APTS) used labeling carbohydrate standards and detection. optimized method applied quantitative analysis fructose glucose by direct injection samples. Apart from...
In this research, contamination levels and the spatial pattern identification, as well human environmental health risk assessments of heavy metals in phreatic groundwater aquifer Oued Souf Valley were investigated for first time. The applied methodology comprised a combination heavy-metal pollution indices, inverse distance weighting, assessment through water ingestion on samples collected from (14) monitoring wells. trend showed Al > B Sr Mn Fe Pb Ni Cr Ba Cu Zn. Similarly, enrichment...
Soil contamination caused by the presence of Cd and excess amount Zn is a widespread concern in agricultural areas, posing significant risks to growth development crops. In this paper, early-stage metal (Cd Zn) accumulation potential rapeseed (Brassica napus L.) grown under different application schemes were assessed determining radicle hypocotyl length micro- macro elemental composition plantlets after 24, 72, 120 h. The results indicated that single co-application significantly reduced...
Abstract In present study the effect of iron (Fe) and manganese (Mn) contamination was assessed by modeling a freshwater food web water, zooplankton ( Daphnia pulex ), zebrafish Danio rerio ) under laboratory conditions. Metals were added to rearing media D. , enriched fed in feeding trial. The elemental analysis zooplankton, fish revealed significant difference treatments compared control. Mn level increased almost parallel with dose supplementation, as well Fe differed statistically. A...
β-Tricalcium phosphate was combined with silica aerogel in composites prepared using the sol-gel technique and supercritical drying. The materials were used this study to check their biological activity bone regeneration potential MG63 cell experiments. sintered 100 °C steps range of 500-1000 °C.
