Essential oils are becoming increasingly popular in medicinal applications because of their antimicrobial effect. Thymus vulgaris L. (Lamiaceae) is a well-known and widely cultivated plant, which used as remedy for cold, cough gastrointestinal symptoms. oil content thyme responsible its activity, however, it has been reported that the chemical composition essential influences biological activity. In order to explore flowering phenophases influence on antibacterial anti-biofilm plant...

Soft tissue integration of dental implants lags behind natural biological teeth mainly because non-optimal surface features. Peri-implant infections resulting in loss supporting bone jeopardize the success implants. Our aim was to compare an anodized design with a turned one for more optimal surface.Morphological and chemical structures Ti surfaces (grade 5: Ti6Al4V) discs were examined by scanning electron microscopy (SEM-EDS), energy dispersive X-ray spectroscopy (EDS), atomic force (AFM)....

There is an increasing need for paleoclimate records from continental settings to better understand the climatic changes during critical periods such as Pliocene and Early Pleistocene. Present data indicates a transition warmer than present-day climate substantially different cooler climate. This study reviews oxygen carbon isotope compositions of mammalian tooth enamel Pleistocene South Central Europe reconstruct spatial distribution temporal vegetation composition precipitation (δ18Oppt)....

The aim of the study was to assess impact four unifloral honeys on food-borne pathogens Pseudomonas aeruginosa and Staphylococcus aureus, by analyzing honeys' antibacterial biofilm degradation effects, as well their antioxidant activity element content. Linden milkweed represented light colored honeys, while goldenrod chestnut darker ones. botanical origin relative frequency pollen types were established with melissopalynological analysis. capacities calculated two single electron transfer...

The biofilm formation of bacteria in different parts the human body can influence success antibiotic therapy. Essential oils (EOs) and their components are becoming increasingly popular point view medicinal applications, because antibacterial efficacy. immortelle EO has been used traditionally as an expectorant; however, there no studies summarizing its effect against respiratory tract bacteria. Our aim was to investigate inhibitory activity (Helichrysum italicum) pathogens such Haemophilus...

Summary It has been claimed that outdoor‐reared suckling piglets do not need iron supplementation. According to practical experience, and non‐iron‐supplemented show a lower performance in comparison with their iron‐supplemented counterparts. The purpose of the present study was determine effect supplementation on piglets. In large Hungarian outdoor pig production unit, 4691 were assigned one two treatment groups. Piglets group 1 ( n = 2344): received no supplementation, whereas 2 2347)...

A two-stage survey was conducted to determine the prevalence of bulimia and bulimic behavior in 2 Hungarian nonclinical samples. In college sample 1.3% females 0.8% males met DSM-III-R diagnostic criteria for nervosa. adolescent no subjects were found, weight control behaviors are infrequent, but attitudinal antecedents present females.

The purpose was to evaluate the degree of conversion (DC), internal adaptation (IA) and closed porosity (CP) short-fiber reinforced resin composites (SFRC) associated with layered or bulk restorative procedures in deep MOD cavities. Eighty third molars standardized cavities (5-mm-depth, 2.5-mm-width) were randomly divided into four groups restored as follows: 1) SFRC; 2) 3) flowable bulk-fill resin-based (RBC); 4) conventional RBC. After one-month wet storage samples subjected micro-computed...

Abstract Today, antibiotic therapies that previously worked well against certain bacteria due to their natural sensitivity, are becoming less effective. Honey has been proven inhibit the biofilm formation of some respiratory bacteria, however few data available on how storage time affects antibacterial effect. The activity black locust, goldenrod, linden and sunflower honeys from three consecutive years (2020, 2021, 2022) was analyzed in 2022 Gram-negative ( Haemophilus influenzae , H....

Despite polymorphism of crystalline active pharmaceutical ingredients (APIs) being a common phenomenon, reports on polymorphic co-crystals are limited. As can vastly affect API properties, controlling polymorph generation is crucial. Control the nucleation through use different solvents during solution crystallization has been used to obtain desirable crystal polymorph. There have two reported forms 4-aminosalicylic acid-sulfamethazine co-crystals. These were found thermodynamic stabilities....

To develop efficient microbial fuel cell systems for green energy production using different waste products, establishing characterised bacterial consortia is necessary. In this study, bacteria with electrogenic potentials were isolated from mud samples and examined to determine biofilm-formation capacities macromolecule degradation. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry identifications have revealed that isolates represented 18 known 4 unknown genuses....

Conductive polymer composites are commonly present in flexible electrodes for neural interfaces, implantable sensors, and aerospace applications. Fused filament fabrication (FFF) is a widely used additive manufacturing technology, where conductive filaments frequently contain carbon-based fillers. In this study, the static dynamic mechanical properties electrical (resistance, signal transmission, resistance measurements during cyclic tensile, bending temperature tests) were investigated...

The eradication of bacterial biofilms remains a persistent challenge in medicine, particularly because an increasing number exhibit resistance to conventional antibiotics. This underscores the importance searching for novel compounds that present antibacterial and biofilm inhibition activity. Various types honey essential oil were proven be effective against biofilm-forming strains. current study demonstrated effectiveness relatively unexplored fennel (FH), (FEO), their combination strains...

Abstract Samples of kidney, blood, lungs, hair, heart, liver, spleen, muscle, ear, rib, skin and faeces were obtained from 200 fattened pigs in 10 abattoirs across Hungary. These analysed triplicate for cadmium lead concentrations by atomic absorption spectrophotometry. The highest found the followed hair then heart lungs. Lead greater than other tissues. Both meat offal below legal limits. There was more variation between abattoirs, there no correlation two elements. Blood concentration...
