Melissa officinalis is an important medicinal plant that used and studied intensively due to its numerous pharmacological effects. This has active compounds with biomedical potential; some are volatile, while others sensitive heat or oxygen. Therefore, increase stability prolong biological activities, the natural extract can be loaded into various nanostructured systems. In this study, different loading systems were obtained from mesoporous silica, like Mobile Composition of Matter family...

Wound dressings for skin lesions, such as bedsores or pressure ulcers, are widely used many patients, both during hospitalization and in subsequent treatment at home. To improve the shorten healing time and, therefore, cost, numerous types of wound have been developed by manufacturers. Considering certain inconveniences related to intolerance some patients antibiotics antimicrobial, antioxidant, curative properties essential oils, we conducted research incorporating these based on polyvinyl...

This study evaluates the antimicrobial and antioxidant activities of five essential oils (EO): pine oil, thyme sage fennel eucalyptus oils. To identify chemical composition oils, we used gas chromatography coupled to a mass spectrometer (GC-MS). EO are predominantly characterized by presence monoterpene hydrocarbons oxygenated monoterpenes, except in case oil which contains phenylpropanoids as its main components. The activity was highlighted on four standard microbial strains (two...

The failure of hip prostheses is a problem that requires further investigation and analysis. Although total replacement an extremely successful operation, the number revision surgeries needed after this procedure expected to continue increase due issues with both bone cement types cementation techniques (depending on producer). To conduct comparative analysis, as surgeon prepared introduced it in body, study's team researchers three commercial cements samples mixed placed them specimens,...

PMMA bone cements are mainly used to fix implanted prostheses and introduced as a fluid mixture, which hardens over time. The problem of infected prosthesis could be solved due the development some new antibacterial cements. In this paper, we show results obtained develop four different modified by using antimicrobial additives, such gentamicin, peppermint oil incorporated in hydroxyapatite, silver nanoparticles ceramic glass matrix (2 4%). structure morphology were investigated SEM EDS. We...

In cytotoxicity their influence on DNA content L929 (NCTC) fibroblasts...

Uncontrollable bleeding continues to stand as the primary cause of fatalities globally following surgical procedures, traumatic incidents, disasters, and combat scenarios. The swift efficient management through application hemostatic agents has potential significantly reduce associated mortality rates. One significant drawback currently available products is their susceptibility bacterial infections at site. As this a prevalent issue that can potentially delay or compromise healing process,...

The developement and regeneration of healthy bone tissue is a complex process that includes the interaction different cell types requires set coordinated processes. loss may occur due to various reasons: surgical removal, trauma (i.e., fractures) or systemic osteoporosis). When natural destroyed, capacity not always satisfactory. result consists therefore in many functional structural aberrations. In order improve accelerate healing process, substitutes have been developed. Hydroxyapatite...

In the current context of climate change and life on Earth, purpose this paper is to establish effects different light treatments (i.e., LEDs—white, blue, red, sunlight) two substrates gauze biochar) garden cress sprouts. respect, sprouts’ fresh weight length were statistically analyzed. case weight, results indicated that most suitable substrate for better growth biochar under all treatments, with a 5.78% increase. On other hand, highest particular value regarding was obtained sunlight...

The immersed components of hydroelectric power plants are permanently in contact with the water stream and their wear occurs by corrosion, erosion cavitation. This damage is usually repaired welding: procedure fast reduces plant downtime. Adopting proper weld procedures crucial for blade performance to establish a protocol following experiment was devised: rectangular samples 600x200x15mm were obtained from discarded used median region 3mm deep groove milled simulate damage. welding using...

The aim of this paper is to demonstrate the effect light treatments using LED-s and sunlight as well charcoal use substratum instead soil or gauze.In it assessed length weight basil (Ocimum basilicum L.) sprouts, namely fresh cotyledons, hypocotyls roots hypocotyls.The tests were done under LED light, be specific, white, red, blue green, sunlight.The used was gauze charcoal.The results showed that when used, higher weights hypocotyls, cotyledons lengths achieved from massive carbon rich...

Abstract: The Willows, belonging to the genus Salix, encompass a vast array of species and hybrids, totaling between 330 500 along with approximately 200 hybrids. These plants are found across continents such as Africa, North America, Europe, Asia, exhibiting diverse forms ranging from trees shrubs prostrate plants. Traditionally, Willows have been utilized in folk medicine due their rich reservoir biologically active compounds, salicin being notable example, serving prodrug for salicylic...

Flame straightening is a technology process used to eliminate deformations. This method relies on local heating of the material correct geometry or damaged parts. In automobile services its main use for repairs less critical deformed components. The maximum temperature and thermal gradient, time, cooling rate number cycles affect mechanical properties since can alter microstructure. aim this research was determine characteristics thin steel plates repaired by associated with plastic...

Hedera helix L. is known for its therapeutic properties, such as analgesic, anti-inflammatory, expectorant activity. It currently that the characteristic effects of ivy extracts are induced by phytocompunds, as: saponins (hederagenin, α and β-hederin, hederacoside B C), phytosterols (sitosterol, stigmasterol, campesterol), flavonoids, falcarinol, falcarinone, scopoline, chlorogenic acid, caffeic phytoestrogens [1]. The purpose our study was to evaluate total saponin content leaves obtained...
