Adjuvants are often required to improve the potentially low immunogenicity of vaccines. In this study, it is proposed to use an emulsion based on fluorocarbons as an adjuvant. Since this emulsion adsorbs only a small range of proteins, apolipoprotein A-I (ApoAI) was used as an anchor. Antigen and ApoAI were combined by creating a fusion construct. Results showed that the combined use of a perfluorocarbon emulsion and ApoAI during immunization significantly increases the specific antibody titer in mice and in its effectiveness this system is close to the incomplete Freund's adjuvant.

Background And Aims: Insulin resistance is considered the most important key mechanism in the development of nonalcoholic fatty liver disease (NAFLD). Some studies have reported that hyperinsulinemia decreases the hepatic secretion of apolipoprotein (Apo) B. Chronic hyperinsulinemia in NAFLD may be responsible for the accumulation of triglycerides in hepatocytes.

The monocyte-to-Apolipoprotein A1 ratio (MAR) emerges as a potentially valuable inflammatory biomarker indicative of metabolic dysfunction-associated fatty liver disease (MASLD). Accordingly, this investigation primarily aims to assess the correlation between MAR and MASLD risk. A cohort comprising 957 individuals diagnosed with type 2 diabetes mellitus (T2DM) participated in this study.

Background: High-density lipoprotein-cholesterol (HDLC) has been considered a cardioprotective factor for several decades. However, its association with outcomes in patients with heart failure with reduced ejection fraction (HFrEF) remains controversial. We aimed to investigate the association of HDLC, apolipoprotein A-I (apoA-I), and the HDL-C/apoA-I ratio with multiple outcomes of HFrEF patients and establish prognostic models using machine learning methods.

Background: Dyslipidemia is a common comorbidity in patients with cancer, yet the impact of abnormal lipid levels on tumor prognosis remains contentious. This study was conducted to synthesize the current evidence regarding the prognostic utility of blood lipid levels, including high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglycerides (TG), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB), in predicting overall survival (OS) and disease-free survival (DFS) in cancer patients.
Methods: A comprehensive literature search was performed across electronic databases to assess the associations between blood lipid levels and OS or DFS in cancer patients.

Photosynthesis, the most important biological process on Earth, converts light energy into chemical energy with essential pigments like chlorophylls and bacteriochlorophylls. The ability to reconstruct photosynthesis in heterotrophic organisms could significantly impact solar energy utilization and biomass production. In this study, we focused on constructing light-dependent biosynthesis pathways for bacteriochlorophyll (BChl) a and bacteriochlorophyllide (BChlide) d and c in the model strain Escherichia coli.
