Eugenol as a promising antibiofilm and anti-quorum sensing agent: A systematic review.

The spread of bacterial resistance has become a significant public health concern, resulting in increased healthcare costs, mortality, and morbidity. Phytochemicals such as Eugenol, the major component of Indian clove and cinnamon essential oils, have attracted attention due to their antimicrobial potential. Thus, this systematic review aims to analyze the existing literature on the antibacterial potential of Eugenol concerning its activity against biofilms, bacterial communication systems (quorum sensing - QS), and associated virulence factors.

Transformations that preserve the uniqueness of the differential form for Lorenz-like systems.

Differential equations serve as models for many physical systems. But, are these equations unique? We prove here that when a 3D system of ordinary differential equations for a dynamical system is transformed to the jerk or differential form, the jerk form is preserved in relation to a given variable and, therefore, the transformed system shares the time series of that given variable with the original untransformed system. Multiple algebraically different systems of ordinary differential equations can share the same jerk form.

pH-Sensitive Hybrid System Based on Eu/Gd Co-Doped Hydroxyapatite and Mesoporous Silica Designed for Theranostic Applications.

Nanomaterials such as pH-responsive polymers are promising for targeted drug delivery systems, due to the difference in pH between tumor and healthy regions. However, there is a significant concern about the application of these materials in this field due to their low mechanical resistance, which can be attenuated by combining these polymers with mechanically resistant inorganic materials such as mesoporous silica nanoparticles (MSN) and hydroxyapatite (HA). Mesoporous silica has interesting properties such as high surface area and hydroxyapatite has been widely studied to aid in bone regeneration, providing special properties adding multifunctionality to the system.

The potential of algae and aquatic macrophytes in the pharmaceutical and personal care products (PPCPs) environmental removal: a review.

The presence of emerging contaminants, such as pharmaceuticals and personal care products (PPCPs), in aquatic environments has received increasing attention in the last years due to the various possible impacts on the dynamics of the natural environment and human health. In global terms, around 771 active pharmaceutical substances or their transformation products have been detected at levels above their respective detection limit. Additionally, 528 different compounds have been detected in 159 countries.

Evaluation of high rate ponds operational and design strategies for algal biomass production and domestic wastewater treatment.

This study evaluated the effect of high rate ponds (HRPs) depth on algal biomass production during domestic wastewater treatment. HRPs were evaluated for 20, 30, and 40 cm depths, with and without CO supplementation. In addition, 40 cm deep HRP with ultraviolet (UV) pre-disinfection was evaluated.

Fabrication and Optical Properties of Strain-free Self-assembled Mesoscopic GaAs Structures.

We use a combined process of Ga-assisted deoxidation and local droplet etching to fabricate unstrained mesoscopic GaAs/AlGaAs structures exhibiting a high shape anisotropy with a length up to 1.2 μm and a width of 150 nm. We demonstrate good controllability over size and morphology of the mesoscopic structures by tuning the growth parameters.

Shoes influence in women posture.

One of the most prevalent aspects is women with complaints of discomfort in the lumbar region for the use of high heeled shoe. Authors described that there may be a relation between attitude and the present discomfort, often associated with muscular fatigue and increase the forces of reaction soil during the use of such footwear. The purpose of this study was to evaluate possible changes postural associated with the use of different types of shoes and barefoot.
