Streszczenie:

Polyethylene glycol (PEG) is a commonly used dispersant for oral administration of hydrophobic agents. PEG is partly absorbed in the small intestine, and the unabsorbed fraction reaches the large intestine; thus, oral administration of PEG may impact the gut microbial community. However, to the best of our knowledge, no study evaluated the effects of PEG on gut commensal bacteria. Herein, we aimed to determine whether oral administration of PEG modifies the gut microbiota. Administration of PEG400 and PEG4000 altered gut microbial diversity in a concentration-dependent manner. Taxonomic analys

Glycol lignin (GL) produced via acidic solvolysis of cedar wood meal with polyethylene glycol (PEG) is a highly functional material. In this study, the effects of wood meal particle size and amount of PEG added on the properties of PEG400-modified GLs (GL400s) were examined. For this purpose, cedar wood meal with four different particle sizes ranging between 0.18 and 2.00 mm and PEG400 at liquid ratios of 5 and 3 with respect to the wood meal were used. Acidic solvolysis at 140 °C successfully decreased the amount of solid residue with increasing GL400 yield and reaction time at both liquid ra

Biomass resources have the potential to replace petroleum-based fuels. Biomass can be converted into pyrolysis oil by pyrolysis method and this oil is of interest as an alternative to fossil fuels used in many areas such as automotive sector. However, pyrolysis oil is difficult to use directly in diesel engines due to its low energy density, high viscosity and water content. The easiest solution is to create mixtures with high cetane content.

Baclofen, a muscle relaxant used for severe pain management, has a narrow absorption window limiting its bioavailability. Enhancing its gastric residence time could potentially improve its absorption and effectiveness. Floating drug delivery systems are a promising approach to prolong drug retention in the stomach. This study aimed to develop a floating bilayer film for the sustained release of baclofen. The core of the film was formulated with baclofen, PVP K90, sodium alginate, and PEG 400 as a plasticizer, while the controlled release layer contained Eudragit RS100 or RLPO with different pl

Hydrogel scaffold has been widely applied as drug delivery systems for treating skin injuries. However, the poor drug loading and rapid drug release of hydrogel restricted their application. In the current study, we present a nanoliposome containing sulforaphane (SF) as a nano-drug delivery system that is encapsulated within the scaffold hydrogel system to overcome these limitations and improve wound healing. The hydrogel substrate consisting of 10% polyvinyl alcohol (PVA)/5% polyethylene glycol 400 (PEG400) was prepared by the freeze–thaw method, and the nanoliposomal system was manufactured

Chromogenic materials, in which optical properties such as luminescence and absorption are altered by external stimuli such as light, heat, and electricity, have potential applications in chemical sensors, biochemical labels, molecular memory, and display devices. Electrofluorochromic (EFC) materials, in which wavelength and/or intensity of their photoluminescence are controlled by electrochemical redox reactions, are innovative materials because they can rapidly and repeatedly convert electrical inputs into visual signals. These EFC phenomena were reported by using small molecules, conjugated

Abstract Skin cancer is currently one of the most common cancers and is defined as an abnormal growth of the skin cells. The goal of this study is to develop a topical delivery system of carvedilol with limonene as the vehicle. Limonene is a major component found in the rinds of citrus fruits and other herbs. It is one of many natural compounds that have demonstrated inhibitory activity in different types of cancers such as breast, lung, and stomach cancer. Furthermore, limonene has shown to increase skin permeation of drugs including carvedilol. The soft agar colony formation assay was used t

Allergic reactions to COVID-19 vaccine components are rare but should be considered. Polyethylene glycol (PEG) is responsible for anaphylaxis in mRNA vaccines. Skin tests have been used in the allergological work-up programs for COVID-19 vaccine evaluation. However, the reproducibility of the skin prick test is time-dependent and the reactivity declines over time. Therefore, we combined the administration of the skin tests with the basophil activation test (BAT) using PEG2000, PEG4000 and DMG-PEG2000, where the BAT was considered positive when the percentage of activated basophils was higher t

Molecular Dynamics (MD) simulation is an alternative solution to reduce cost and time.
