In developing tumor, macrophages are one major immune infiltrate that not only contributes in shaping up of tumor microenvironment (TME) but also have the potential of determining the fate of tumor in terms of its progression. Phenotypic plasticity of macrophages primarily channelizes them to alternative (M2) form of tumor associated macrophages (TAM) in the TME. One of the key tumor derived components that plays a crucial role in TAM polarization from M1 to M2 form is lactic acid and has prominent role in progression of malignancy. The role of lactic acid as signalling molecule as well as an immunomodulator has recently been recognized. This review focuses on the mechanism and signalling that are involved in lactic acid induced M2 polarization and possible therapeutic strategies for regulating lactic acidosis in TME.

The aim of this experiment was to investigate the effects of rumen fluid and molasses on the nutrient composition, fermentation quality, and microflora of Caragana korshinskii Kom. The trial included four treatments: a control group (CK) without additives and experimental groups supplemented with 7% rumen fluid (R), 4% molasses (M), and 7% rumen fluid + 4% molasses (RM). 15 days and 60 days of ensiling.

The sepsis-induced acute lung injury (ALI) still represents one of the leading causes of death in critically ill patients, underscoring the need for novel therapies. Excessive activation of immune cells and damage of reactive oxygen species (ROS) are the main factors that exacerbate lung injury. Here, the multifaceted immunomodulatory nanocomplexes targeting the proinflammatory neutrophilic activation and ROS damage are established.

Background And Objectives: The most common cause of severe foodborne salmonellosis is Typhimurium. Its interaction with intestinal epithelial cells is little known. Lactic acid bacteria (LAB) were recognized as a prominent probiotic gastrointestinal microbiota of humans and animals that confer health-promoting and protective effects.

Polymeric coronary stents, like the ABSORB™, are commonly used to treat atherosclerosis due to their bioresorbable and cell-compatible polymer structure. However, they face challenges such as high strut thickness, high elastic recoil, and lack of radiopacity. This study aims to address these limitations by modifying degradable stents produced by additive manufacturing with poly(lactic acid) (PLA) and poly(ε-caprolactone) (PCL) with degradable metallic coatings, specifically zinc (Zn) and magnesium (Mg), deposited via radiofrequency (rf) magnetron sputtering.
