Light-guided actin polymerization drives directed motility in protocells.

Motility is a hallmark of life's dynamic processes, enabling cells to actively chase prey, repair wounds, and shape organs. Recreating these intricate behaviors using well-defined molecules remains a major challenge at the intersection of biology, physics, and molecular engineering. Although the polymerization force of the actin cytoskeleton is characterized as a primary driver of cell motility, recapitulating this process in protocellular systems has proven elusive.

Comparison of the Effects of Hydralazine and Labetalol on Intracranial Pressure When Used for Blood Pressure Control in Patients With Intracranial Hemorrhage: A Retrospective Study.

Background Recommendations on optimal agents to manage blood pressure (BP) in patients with an intracranial hemorrhage (ICH) are lacking. A case series suggests that hydralazine can cause intracranial pressure (ICP) elevation in an ICH. The purpose of this study was to compare the effects of intravenous (IV) hydralazine to IV labetalol on ICP in patients with ICH.

Histological findings of corneal tissue after failed phototherapeutic keratectomy in macular corneal dystrophy - a case report.

Background: Macular corneal dystrophy is a rare inherited disease of the cornea leading to deposits mainly in the stroma. Affected patients suffer from progressive loss of visual acuity which should be treated with penetrating keratoplasty. This is the first case report describing the clinical and histopathological findings of corneal tissue after failed phototherapeutic keratectomy (PTK) in a patient with macular corneal dystrophy.

Benchmarking Visual Performance with Monofocal Intraocular Lenses with and without Enhanced Optical Properties in a Nighttime Driving Simulator Environment: A Proof-of-Concept Study.

Background: The purpose of this study is to introduce a method for benchmarking intraocular lenses during driving activities under highly standardized conditions, specifically with regard to visual acuity (VA) and contrast sensitivity (CS). Therefore, patients with intraocular lens (IOL) implants ICB00 (Tecnis Eyhance, Johnson & Johnson, Santa Ana, CA, USA) vs. CNA0T0 (Clareon, Alcon Laboratories Inc.
