The role of solar photolysis in the atmospheric removal of methacrolein oxide and the methacrolein oxide-water van-der Waals complex in pristine environments.

Biogenic hydrocarbons are emitted into the Earth's atmosphere by terrestrial vegetation as by-products of photosynthesis. Isoprene is one such hydrocarbon and is the second most abundant volatile organic compound emitted into the atmosphere (after methane). Reaction with ozone represents an important atmospheric sink for isoprene removal, forming carbonyl oxides (Criegee intermediates) with extended conjugation.

Outcomes of Prolene Gonioscopy Assisted Transluminal Trabeculotomy in Primary Open Angle Glaucoma and Pseudoexfoliation Glaucoma: A Comparative Study.

Prcis: Gonioscopy-assisted transluminal trabeculotomy (GATT) provides greater intraocular pressure (IOP) reduction in pseudoexfoliative glaucoma (PXG) than in primary open angle glaucoma (POAG) in the first year of surgery; however, the difference between groups equalizes in the long term.

Purpose: To compare outcomes of GATT in eyes with POAG and PXG.

Methods: Single-center, retrospective, comparative case-series.

Early detection of change patterns in COVID-19 incidence and the implementation of public health policies: A multi-national study.

Objectives: The COVID-19 pandemic caused by the novel SARS-CoV-2 coronavirus has drastically altered the global realities. Harnessing national scale data from the COVID-19 pandemic may better inform policy makers in decision making surrounding the reopening of society. We examined country-level, daily-confirmed, COVID-19 case data from the World Health Organization (WHO) to better understand the comparative dynamics associated with the ongoing global pandemic at a national scale.

A mixture model with Poisson and zero-truncated Poisson components to analyze road traffic accidents in Turkey.

The analysis of traffic accident data is crucial to address numerous concerns, such as understanding contributing factors in an accident's chain-of-events, identifying hotspots, and informing policy decisions about road safety management. The majority of statistical models employed for analyzing traffic accident data are logically count regression models (commonly Poisson regression) since a count - like the number of accidents - is used as the response. However, features of the observed data frequently do not make the Poisson distribution a tenable assumption.

Value of Echo-Planar Diffusion-Weighted Magnetic Resonance Imaging for Detecting Tympanomastoid Cholesteatoma.

Objective: The aim of this study was to evaluate the diagnostic accuracy of echo-planar diffusion-weighted magnetic resonance imaging (EP-DWI) and high-resolution computed tomography (HRCT) in the detection and localization of cholesteatoma.

Materials And Methods: Fifty-four patients were prospectively included in this study. Patients with suspected primary or residual cholesteatoma were evaluated by EP-DWI and HRCT before tympanomastoid surgery.
