Purpose: Assessment of the density of endothelial cells after usage of gentamicin in irrigation-aspiration fluid.
Material And Methods: 60 patients subjected to extracapsular cataract extraction with intraocular lens implantation. In 30 eyes irrigation was performed with Ringer fluid (group I) and in 30 eyes Ringer fluid with gentamicin (group II) 4 mg gentamicin were added to 500 ml of Ringer fluid obtaining the concentration 8 micrograms/ml. Evaluation of endothelial cells density was carried before operation, 1 month and 6 months after.
Results: Percentage endothelial cells loss in group I was 7.8% 1 month postoperatively and 14.5% 6 months after operation and in group II 8.5% and 14.87%, respectively.
Conclusion: Gentamicin added to irrigation-aspiration fluid doesn't cause enhanced endothelial cells loss during extracapsular cataract extraction.

Objective: Loss of function of the phospholipid scramblase (PLS) TMEM16F results in Scott Syndrome, a hereditary bleeding disorder generally attributed to intrinsic platelet dysfunction. The role of TMEM16F in endothelial cells, however, is not well understood. We sought to test the hypothesis that endothelial TMEM16F contributes to hemostasis by measuring bleeding time and venous clotting in endothelial-specific knockout (ECKO) mice.

Definitive hematopoietic stem and progenitor cells (HSPCs) arise from a small number of hemogenic endothelial cells (HECs) within the developing embryo. Understanding the origin and ontogeny of HSPCs is of considerable interest and potential therapeutic value. It has been proposed that the murine placenta contains HECs that differentiate into HSPCs.

To successfully establish and maintain pregnancy in pigs, a variety of factors must work together at the maternal-conceptus interface to form an immune environment appropriate for both the mother and the conceptus. Our transcriptomics study has shown that cluster of differentiation ligand 40 (CD40L) and its receptor CD40, which are known to play important roles in regulating cell- and antibody-mediated immunity, are expressed in the endometrium during early pregnancy. However, the roles of the CD40L and CD40 signaling system are not well understood.

Somatic activating mutations in KRAS can cause complex lymphatic anomalies (CLAs). However, the specific processes that drive KRAS-mediated CLAs have yet to be fully elucidated. Here, we used single-cell RNA sequencing to construct an atlas of normal and KrasG12D-malformed lymphatic vessels.
