Micro-structured heat exchanger for cryogenic mixed refrigerant cycles
, 2017 Mixed refrigerant cycles (MRCs) offer a cost- and energy-efficient cooling method for the temperature range between 80 and 200 K. The performance of MRCs is strongly influenced by entropy production in the main heat exchanger.

Animal Models and Experimental Medicine, EarlyView.DPSCs, hepatocytes, and exosomes were tested for liver fibrosis therapy. Exosome‐based treatment exhibited superior antioxidative and regenerative effects. Liver enzymes, oxidative stress, and profibrotic markers were significantly reduced. α‐SMA, desmin, and related gene expression were downregulated.

Animal Models and Experimental Medicine, EarlyView.ErZhi formula (EZF) is composed of Ligustri Lucidi Fructus (LLF) and Ecliptae herba (EH). Ovariectomized (OVX) and sham rats received 12‐week intragastric treatment with EZF, alendronate, and vehicle saline. Gastrocnemius tissues were harvested to systematically evaluate pharmacodynamic changes in skeletal muscle morphology, mitochondrial ...
