Background: Posterior polar cataracts are challenging even for skilled cataract surgeons due to the high risk of posterior capsule rupture and vitreous loss during cataract surgery; hence, it is important to know how to manage such cases.
Purpose: In this video, we describe the necessary precautions and steps to be taken to prevent and manage complications in phacoemulsification cataract surgery for posterior polar cataracts.
Synopsis: The video contains ten tips to follow to avoid complications while performing phacoemulsification cataract surgery in patients with posterior polar cataracts and includes preoperative identification on slit-lamp examination, size of capsulorhexis, avoidance of hydrodissection, technique of nucleus management, viscoelastic injection to keep the anterior chamber formed, epinucleus and cortical matter removal, posterior capsular rupture management, anterior vitrectomy, and intraocular lens (IOL) implantation in eyes with posterior capsular rupture.
Highlights: The video highlights ten different steps to be followed in the surgical management of patients with posterior polar cataract which, if followed meticulously, can give excellent outcomes in these patients.
Conclusion: Posterior polar cataracts can be managed with phacoemulsification, with good visual outcomes if these precautions are followed.

Background: Several nephrometry scores have been proposed and applied in the adult population. We previously established a novel model to predict the feasibility of nephron-sparing surgery (NSS) in pediatric bilateral Wilms tumor (WT) patients. This study aimed to evaluate whether our model had better predictive performance compared to other scores.

Natural nutshell extract was obtained by mechanical compression. The extract was combined with ethanol and a nonionic surfactant, and it was labeled as EES. The EES inhibitor effect on S135 carbon steel, exposed to a simulated marine-coastal environment (SME), was deduced by mass loss measurement, adsorption isotherm, electrochemical measurements, and surface analysis.

Symmetry is a salient visual feature in the natural world, yet the perception of symmetry may be influenced by how natural lighting conditions (e.g., shading) fall on the object relative to its symmetry axis.

Small GTPases of the Rho family play a central role in the regulation of cell motility by controlling the remodeling of the actin cytoskeleton. In the amoeboid cells of Dictyostelium discoideum, the active form of the Rho GTPase Rac1 regulates actin polymerases at the leading edge and actin filament bundling proteins at the posterior cortex of polarized cells. We monitored the spatiotemporal dynamics of Rac1 and its effector DGAP1 in vegetative amoebae using specific fluorescent probes.

A total of 230 cleared and alizarin stained and 136 radiographed specimens of Darevskia belonging to 47 nominal taxa (species, subspecies or singular clades) including the seven parthenogenetic ones and a triploid hybrid were studied. Sixteen osteological characters in all the tried species were analyzed. These characters by corporal regions were: skull characters: 1.
