Highly sensitive metamaterial-based microwave sensor for the application of milk and dairy products.

In this work, a novel, to the best of our knowledge, metamaterial-based microwave sensor is designed, numerically simulated, and experimentally tested for milk and dairy products in the frequency range of 8 to 9 GHz. The proposed structure is composed of copper split-ring resonators printed on Arlon Diclad 527 dielectric substrate. Reflection coefficient was determined by using numerical simulation, and the structure was experimentally tested to validate the sensor at the X band frequency.

Evaluation of the Corneal Layers in Meibomian-Gland-Dysfunction-Related Dry Eye by In Vivo Slit-Scanning Confocal Microscopy.

In the current study it was aimed to evaluate the findings of cornea in Dry Eye related Meibomian Gland Dysfunction through in vivo confocal microscopy. 30 patients of Dry Eye related Meibomian Gland Dysfunction (DEMGD) and 30 healty individuals were included. 46 eyes of 30 DEMGD patients (group 1) and 46 eyes of 30 healthy individuals (group 2) were formed as control group and images were captured from the centre of the cornea.

Ophthalmic findings in acute mercury poisoning in adults: A case series study.

The aim of this study is to report ophthalmic findings of acute mercury poisoning in 48 adults referred to emergency department. Full ophthalmologic examination including the best corrected visual acuity, external eye examination, reaction to light, a slit-lamp examination, funduscopy, intraocular pressure measurements, and visual field (VF) and color vision (CV) tests were performed at the presentation and repeated after 6 months. The parametric values of VF test, the mean deviation (MD), and pattern standard deviation (PSD) were recorded in order to compare patients and the 30 healthy controls.
