Various chemical compounds, including surfactants, when introduced to culture media may increase the permeability of cellular membranes and thereby affect the quantity of metabolites excreted by cells. The aim of the present study was to evaluate the impact of detergents including Triton X-100, Span 20 and Tween 80 on erythritol production from glycerol by Yarrowia lipolytica Wratislavia K1 in a shake-flask experiment, batch and fed-batch cultures. When Span 20 was added to a fed-batch culture with glycerol as a carbon source (300gL(-1)), erythritol production increased by 15% compared to the culture without the surfactant where it reached 142gL(-1) after 5 days, which corresponded to 0.47gg(-1) yield and productivity of 1.1gL(-1)h(-1). Therefore, it was concluded that Span 20 considerably enhanced the production of this polyol from glycerol.

Purpose Of Review: This review explores the evolving understanding of efferocytosis - the clearance of dead or dying cells by phagocytes - in the context of atherosclerosis. It highlights recent discovers in cell death modalities, impaired clearance mechanisms and emerging therapeutic strategies aimed at restoring efferocytosis to stabilize plaques and resolve inflammation.
Recent Findings: Recent studies have expanded the scope of efferocytosis beyond apoptotic cells to include other pro-inflammatory cell death modes, including pyroptosis, necroptosis and ferroptosis, revealing context-dependent clearance efficiency and immunological outcomes.

Achieving a crack-free, high-surface-area photoanode is essential for maximizing the efficiency of dye-sensitized solar cells (DSSCs). In this work, rutile titanium dioxide (rTiO) nanoflowers were synthesized hydrothermally and then conformally coated with copper(I) oxide (CuO) by RF magnetron sputtering to seal pre-existing cracks and to create a nanothorn surface favorable for dye adsorption. Systematic control of the sputtering time identified 60 min as optimal condition, yielding a photoanode thickness of about 6.

Dispersing iridium onto high-specific-surface-area supports is a widely adopted strategy to maximize iridium utilization in anode catalysts of proton exchange membrane water electrolysis (PEMWE). However, here we demonstrate that the overall cell performance, including initial efficiency and long-term stability, does not benefit from the typical high specific surface area of catalyst supports. The conventional understanding that high iridium utilization on high-specific-surface-area supports increases activity holds only in aqueous electrolytes, while under the typical working conditions of PEMWE, the mass transport within the anode catalyst layers plays a more significant role in the overall performance.

Aims: The increasing antimicrobial resistance, particularly in Acinetobacter baumannii, complicates the treatment of infections, leading to higher morbidity, mortality, and economic costs. Herein, we aimed to determine the in vitro antimicrobial, synergistic, and antibiofilm activities of colistin (COL), meropenem, and ciprofloxacin antibiotics, and curcumin, punicalagin, geraniol (GER), and linalool (LIN) plant-active ingredients alone and in combination against 31 multidrug-resistant (MDR) A. baumannii clinical isolates.

Purpose: To evaluate the efficacy and underlying mechanism of advanced optimal pulse technology intense pulsed light (AOPT) in low-energy triple-pulse long-width mode (AOPT-LTL) for melasma treatment.
Methods: An in vivo guinea pig model of melasma was established through progesterone injection and ultraviolet B radiation. Three sessions of AOPT-LTL treatment were performed weekly.
