Comparative analysis of light storage in antirelaxation-coated and buffer-gas-filled alkali vapor cells.

We explore light storage in antirelaxation-coated and buffer-gas-filled alkali vapor cells, employing electromagnetically induced transparency (EIT) in warm rubidium vapor. We conduct a comparative study of light storage performance under identical experimental conditions for these two cell types. Using a buffer-gas-filled cell resulted in approximately a tenfold improvement in memory efficiency and storage time compared to antirelaxation-coated cells.

MRI Assessment of the Early Disc Degeneration Two Levels above Fused Lumbar Spine Segment: A Comparison after Unilateral and Bilateral Transforaminal Lumbar Interbody Fusion (TLIF) Procedure.

Background: Adjacent segment degeneration (ASD) has become a great concern as a late complication in patients following fusion spine surgery with a potential need for revision surgery. Segments above the fused spine have higher mobility and they are especially prone to accelerated disc degeneration. The purpose of our study is to investigate early disc degenerative changes two levels above a surgically fused lumbar spine segment and to compare MRI analyses after unilateral and bilateral TLIF procedures.

Juvenile diabetes eye complications and treatment.

Background/aim: Diabetes mellitus (DM) is a metabolic disorder characterized by hyperglycemia. The aim of this study was to explore the prognosis of patients with juvenile DM regarding diabetic eye complications, as well as the course of the diabetic eye disease related to the treatment undertaken.

Methods: The study series involved 33 patients with juvenile DM during the period 1992-2007.

The prognosis of CMV retinitis among patients with AIDS in Serbia.

Background: Cytomegalovirus (CMV) end-organ diseases, including CMV retinitis, are major opportunistic events in terminal AIDS patients.

Methods: A retrospective study of 30 AIDS patients with CMV retinitis treated between 1997 and 2007 in Serbia was conducted to examine the prognosis and factors associated with survival.

Results: Eighteen (60%) patients survived the mean follow-up period of 46.

[Immune recovery vitritis].

Introduction: Immune recovery vitritis (IRV) is symptomatic vitritis of > 1 + severity associated with inactive cytomegalovirus (CMV) retinitis. It is an opportunistic infection of the eye, in the patients who suffer from AIDS, and is treated with a highly active antiretroviral therapy (HAART). As a result of this therapy, there is an immune reconstitution in the body and inflammation of the vitreous body.
