The pathological retinal angiogenesis often causes blindness. Current anti-angiogenic therapy for proliferative retinopathy targets the vascular endothelial growth factor (VEGF), but many patients do not radically benefit from this therapy. Herein, we report that circulating prostaglandin (PG) F metabolites were increased in type 2 diabetic patients with proliferative retinopathy, and the PGF receptor (Ptgfr) was upregulated in retinal endothelial cells (ECs) from a mouse model of oxygen-induced retinopathy (OIR).

Background: Osteoporosis is a common metabolic bone disease without effective treatment. Bone marrow-derived mesenchymal stem cells (BMSCs) have the potential to differentiate into multiple cell types. Increased adipogenic differentiation or reduced osteogenic differentiation of BMSCs might lead to osteoporosis.

Article Synopsis
  • * Findings show a decrease in Aldob and an increase in G6PD in human HCC tumors, which correlate with worse patient outcomes, and deleting Aldob in mice leads to increased tumor growth due to higher G6PD activity.
  • * The research suggests that Aldob helps inhibit G6PD through a complex involving p53, independent of its enzymatic activity, indicating

Impaired wound healing is commonly encountered in patients with diabetes mellitus, which may lead to severe outcomes such as amputation, if untreated timely. Macrophage plays a critical role in the healing process including the resolution phase. Although magnetic therapy is known to improve microcirculation, its effect on wound healing remains uncertain.

Dysregulation of cholesterol metabolism represents one of the major risk factors for atherosclerotic cardiovascular disease (CVD). Oxidized cholesterol esters (oxCE) in low-density lipoprotein (LDL) have been implicated in CVD but the underlying mechanisms remain poorly defined. We use a targeted lipidomic approach to demonstrate that levels of oxCEs in human plasma are associated with different types of CVD and significantly elevated in patients with myocardial infarction.

Oxidative stress and inflammation are two major contributing factors to atherosclerosis, a leading cause of cardiovascular disease. Oxidation of phospholipids on the surface of low density lipoprotein (LDL) particles generated under oxidative stress has been associated with the progression of atherosclerosis, but the underlying molecular mechanisms remain poorly defined. We identified a novel series of oxidation products containing the cyclopentenone moiety, termed deoxy-A/J-isoprostanes-phosphocholine, from 1-palmitoyl-2-arachidonoyl--glycero-3-phosphocholine using mass spectrometry and by comparison to a chemically synthesized standard.

Objective: To establish a convenient, practical and environmental method for extracting and isolating shikimic acid.

Methods: The content of shikimic acid was measured by RP-ion-pair HPLC, the effects of different pH, temperature, sample concentration and eluate concentration on 717 anion exchange resin were studied.

Results: The yield of shikimic acid was 96.
