Study on the insulin--receptor interaction of the plasma membranes of liver cells demonstrated a reverse dependence of insulin concentration in the blood and the number of insulin-binding sites on the membranes. Using isolated adipocytes, it was shown that at a constant number of receptors the receptor density is changed. These changes are correlated with the decrease of biological effects in experimental obesity accompanied by hyperinsulinism. In the case of streptosotocin diabetes (simulated hypoinsulinism) no correlation between insulin binding and its biological effects was observed, which can be accounted for by disturbances in transmission of the signal from the insulin--receptor complex to the enzymatic systems of the cells.

The extreme electric fields created in high-intensity laser-plasma interactions could generate energetic ions far more compactly than traditional accelerators. Despite this promise, laser-plasma accelerator experiments have been limited to maximum ion energies of ∼100 MeV/nucleon. The central challenge is the low charge-to-mass ratio of ions, which has precluded one of the most successful approaches used for electrons: laser wakefield acceleration.

Background: Lipoprotein(a) [Lp(a)] has been independently associated with increased cardiovascular risk.
Objectives: The authors examined the effect of monoclonal antibody proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9is) on plasma Lp(a) levels across multiple trials.
Methods: Studies were retrieved comparing the effect of PCSK9i vs placebo on Lp(a) levels.

Background: Kidney fibrosis is a suggested cause of kidney failure and premature mortality. Because collagen type VI is closely linked to kidney fibrosis, we aimed to evaluate whether urinary endotrophin, a collagen type VI fragment, is associated with graft failure and mortality among kidney transplant recipients (KTR).
Methods: In this prospective cohort study, KTR with a functioning graft ≥1-y posttransplantation were recruited; 24-h urinary endotrophin excretion was measured using an ELISA method.

Purpose: HA121-28, a novel multi-targeting tyrosine kinase inhibitor, has dual efficacy against tumor growth and neovascularization. The objectives of this study were to assess the effect of high-fat and high-calorie food on the pharmacokinetic (PK) profile and safety of HA121-28 tablet in healthy subjects.
Patients And Methods: A single-dose, randomized, open-label, two-period, crossover-designed phase I clinical trial was conducted.
