Prenatal Exposure to Poly-/Per-Fluoroalkyl Substances Is Associated with Alteration of Lipid Profiles in Cord-Blood

Researchers combined determination of bile acids and molecular lipids by liquid chromatography with ultra-high-resolution mass spectrometry, and separately quantified cord blood concentrations of sixteen poly-/per-fluoroalkyl substances in a cohort of Chinese infants in a cross-sectional study.

Improving Motor Neuron-Like Cell Differentiation of hEnSCs by the Combination of Epothilone B Loaded PCL Microspheres in Optimized 3D Collagen Hydrogel

Providing a 3D permissive environment with epothilone B significantly improved motor neuron-like cell differentiation and maturation of human endometrial stem cells (hEnSCs) and was a promising approach to replace lost neurons after spinal cord injury.

Flavonoids Derived from Anemarrhenae Rhizoma Ameliorate Inflammation of Benign Prostatic Hyperplasia via Modulating COX/LOX Pathways

Scientists reported that Anemarrhenae Rhizoma flavonoids inhibited benign prostatic hyperplasia-related inflammation in vivo and in vitro by targeting arachidonic acid metabolism and interfering with cyclooxygenase (COX) and lipoxygenase (LOX) pathways.

Comparison of the Blood, Bone Marrow, and Cerebrospinal Fluid Metabolomes in Children with B Cell Acute Lymphoblastic Leukemia

Researchers profiled end-induction plasma, marrow, and cerebrospinal fluid (CSF) from ten children with b-cell acute lymphoblastic leukemia using liquid chromatography-mass spectrometry and observed plasma-marrow correlations for metabolites in pathways associated with end-induction residual disease and plasma-CSF correlations for a biomarker of fatigue.
