Formulation and Physicochemical Stability Evaluation of a Polyherbal Cream Incorporating Turmeric, Neem, Green Tea, and Aloe Vera Extracts

Background: Skin aging is a multifactorial biological process driven by intrinsic factors such as genetic changes and hormonal decline, and extrinsic factors, primarily ultraviolet (UV) radiation, that trigger oxidative stress, chronic inflammation, collagen degradation by matrix...

Assessment of small watershed stormwater sampling methods

ABSTRACT Measurements of contaminants in runoff are essential for stormwater management. Sampling accuracy is difficult to assess due to the cost and labor of field studies and the large variation in runoff behavior between sites, rain events, and pollutants. Stormwater sampling...

A bundled anti-parallel cytochrome nanowire structure suggests roles in cell-cell electron transfer and biofilm formation

ABSTRACT Long-range extracellular electron transfer enables respiring microbes to use minerals, organisms, or electrodes as electron acceptors by transporting electrons microns away from the cell surface. This process is primarily studied in Geobacter sulfurreducens , which produ...

Structure-Based Insights into the Molecular Mechanisms of LuxR-Type Quorum Sensing Receptors

Quorum sensing (QS) enables bacteria to coordinate collective behaviors in response to population density. LuxI/R QS systems, common among gram-negative bacteria, consist of a LuxI-type synthase that produces an N- acyl L -homoserine lactone (AHL) signaling molecule and a LuxR-ty...
