Ultrafiltration with a hollow fiber device was studied as an alternative method to the lyophilization or thin-layer distillation techniques in the production of salt-poor, concentrated human albumin preparations for clinical use. A number of process parameters are discussed. Combination of gel filtration and ultrafiltration provides an interesting alternative to the currently used systems.

Neuroinflammation plays a key role in the development of neurodegenerative diseases, with microglia regulating this process through pro-inflammatory M1 and anti-inflammatory M2 phenotypes. Studies have shown that human umbilical cord mesenchymal stem cells (hUCMSCs) modulate neuroinflammation by secreting anti-inflammatory cytokines. Photobiomodulation (PBM), a non-invasive therapy, has demonstrated significant potential in alleviating neuroinflammation.

Blood components play a crucial role in maintaining human health and accurately detecting them is essential for medical diagnostics. A cutting-edge sensor utilizing PCF revealed to precisely identify a wide range of blood components with WBCs (white blood cells), RBCs (red blood cells), HB (hemoglobin), platelets, and plasma. A numerical analysis was performed using COMSOL Multiphysics software to assess the capabilities of the sensor.

Clinical benefits of immunotherapy in colorectal cancer (CRC) are limited due to the low immunogenicity and immunosuppressive tumor microenvironment. Fusobacterium nucleatum (Fn) is discovered to colonize CRC tumors and dampen immunotherapy by fostering an immunosuppressive TME. Herein, a controllable "Shielding-deshielding" N-acetylgalactosamine (GalNAc)-derived photothermal nanotherapeutic is developed to mediate cascade targeting toward tumor and intratumoral Fn for enhanced photothermal-immunotherapy.

Many hydrofluorocarbon refrigerants used in air-conditioning and refrigeration equipment are being phased out based on international restrictions to reduce global warming. Over 1 billion kilograms of hydrofluorocarbons are in use, and recycling is imperative to preventing the release of these greenhouse gases into the atmosphere. We report on composite hollow fiber membranes that can efficiently separate a mixture of difluoromethane and pentafluoroethane that is used worldwide in air conditioners.
