Published: January 2025

Loss of periocular skin due to cancer, trauma, or surgery is a major reconstructive challenge; resultant tissue contracture can cause eyelid malposition with poor functional and aesthetic outcomes. We describe the successful use of cryopreserved umbilical cord amniotic membrane as a wound covering and scaffold for periorbital anterior lamellar defects. This is a retrospective case series of 4 patients (mean 21 years, range 9-30 years, 3 male) who underwent periocular reconstruction with umbilical cord amniotic membrane of 9 different sites. Follow-up time ranged from 10 to 22 months. All wounds healed successfully with a good functional eyelid position. Umbilical cord amniotic membrane is readily available, has antibacterial and anti-inflammatory properties, provides a structural scaffold for cell adhesion and growth, and contains biological factors that promote cell proliferation/remodeling. We demonstrate that the umbilical cord amniotic membrane is an effective substitute for full-thickness skin grafting in the periocular area, particularly with skin loss secondary to burns and/or trauma.

Our objective is to determine the protein and complements constituents of Cord blood Platelet-rich plasma (CB-PRP), based on the hypothesis that it contains beneficial components capable of arresting or potentially decelerating the advancement of atrophic age-related macular degeneration (dry-AMD), with the support of radiomics. Two distinct pools of CB-PRP were assessed, each pool obtained from a total of 15 umbilical cord-blood donors. One aliquot of each pool respectively was subjected to proteomic analysis in order to enhance the significance of our findings, by identifying proteins that are shared between the two sample pools and gaining insights into the pathways they are associated with.

The escalating diabetes prevalence has heightened interest in innovative therapeutic strategies for this disease and its complications. Human amniotic epithelial stem cells (HAESCs), originate from the innermost layer of the placenta closest to the fetus and express stem cell markers in the amniotic membrane's umbilical cord attachment area, which have garnered significant attention. This article critically examines emerging research advancements and potential application values of hAESCs in treating diabetes and its complications.

Introduction: MRTX1133 is a selective and reversible small molecule inhibitor of KRAS (G12D), which significantly delays the progression of solid tumors. However, no study on the absorption, distribution, and excretion of MRTX1133.

Methods: A fast ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry method was developed for the determination of MRTX1133 in rat plasma, tissue homogenate, and urine.

Background: Due to the lack of effective treatment options, the prognosis of patients with relapsed/refractory acute myeloid leukemia (R/R AML) remains poor. Although chimeric antigen receptor (CAR)-T-cell therapy has shown promising effects in acute lymphoblastic leukemia (ALL) and lymphoma, its application in R/R AML is limited by "off-target" effects, which lead to severe bone marrow suppression and limit its clinical application. CAR-natural killer (NK) cells not only exhibit antitumor effects but also demonstrate increased safety and universality.
