Purpose: To compare safety and efficacy of new nanolaser photofragmentation technique with standard ultrasound phacoemulsification cataract surgery technique. Metods: A group of 20 patients - 40 eyes who underwent bilateral cataract surgery, one eye with ultrasound phacoemulsification (group I), n = 20 fellow eye with nanosecond laser framentation (group II ). Lens Opacities Classification System III was used to classify cataract stage. All 40 eyes had stage III cataract, Nucleus Opalescence was NO2 - NO3. Uncorrected visual acuity (UCVA), endothelial cells density (DEC), hexagonal cells rate, index of endothelial cells pleomorfism, and corneal thickness were evaluated prior to surgery and at day 7 follow up.
Results: All 40 eyes had uneventful surgery,without complications. Preoperative UCVA in group I was 0,70±0,07 and 0,68 ± 0,10 in group II. At follow up check 7 days after surgery UCVA was 0,98 ± 0,05 in group 1 and 0,98 ± 0,04 in group II (p-NS). The mean DEC (cells/mm2) before surgery was 2508 ± 205,54 in group 1 and 2472 ± 287,85 in group II. After surgery density decreased to 2024,92±271,50 in group 1 and 2138,5 ± 390,85 in group II. Difference in endothelial cells decrease between groups showed no statistical significance. There was no statistical significance in differences of hexagonal cells rate and corneal thickness between both groups pre and postoperatively.
Conclusion: Nanolaser lens photofragmentation and ultrasound phacoemulsification can be considered equal regarding impact on endothelial cells.

Introduction: Hemodynamic forces play a crucial role in modulating endothelial cell (EC) behavior, significantly influencing blood vessel responses. While traditional in vitro studies often explore ECs under static conditions, ECs are exposed to various hemodynamic forces in vivo. This study investigates how wall shear stress (WSS) influences EC metabolism, focusing on the interplay between WSS and key metabolic pathways.

Cardiovascular illnesses are multifactorial disorders and represent the primary reasons for death worldwide, according to the World Health Organization. As a signaling molecule, nitric oxide (NO) is extremely permeable across cellular membranes owing to its unique molecular features, like its small molecular size, lipophilicity, and free radical properties. Some of the biological effects of NO are vasodilation, inhibition in the growth of vascular smooth muscle cells, and functional regulation of cardiac cells.

This review explores the intricate connections between Drosophila models and the human blood-brain barrier (BBB) with nanoparticle-based approaches for neurological treatment. Drosophila serves as a powerful model organism due to its evolutionary conservation of key biological processes, particularly in the context of the BBB, which is formed by glial cells that share structural and functional similarities with mammalian endothelial cells. Recent advancements in nanoparticle technology have highlighted their potential for effective drug delivery across the BBB, utilizing mechanisms such as passive diffusion, receptor-mediated transcytosis, and carrier-mediated transport.

Background And Purpose: The cortical high-flow sign has been more commonly reported in oligodendroglioma, IDH-mutant and 1p/19q-codeleted (ODG IDHm-codel) compared to diffuse glioma with IDH-wildtype or astrocytoma, IDH-mutant. Besides tumor types, higher grades of glioma might also contribute to the cortical high flow. Therefore, we investigated whether the histological cortical vascular density or CNS WHO grade was associated with the cortical high-flow sign in patients with ODG IDHm-codel.

Nerve signaling within the tumor microenvironment (TME) plays a critical role in the initiation, progression, and metastasis of solid tumors. Due to their highly responsive behavior and activation upon injury and cancer onset, this review specifically focuses on how sympathetic nerves rewire the TME. Within tumors, sympathetic nerves closely interact with various TME components, and their combined signaling often shifts tumor-intrinsic physiology toward tumor-supportive phenotypes.
