Polarization-Sensitive OCT Imaging of Scleral Abnormalities in Eyes With High Myopia and Dome-Shaped Macula.

Importance: The relevance of visualizing scleral fiber orientation may offer insights into the pathogenesis of pathologic myopia, including dome-shaped maculopathy (DSM).

Objective: To investigate the orientation and density of scleral collagen fibers in highly myopic eyes with and without DSM by polarization-sensitive optical coherence tomography (PS-OCT).

Design, Setting, And Participants: This case series included patients with highly myopic eyes (defined as a refractive error ≥6 diopters or an axial length ≥26.

Simultaneous balancing of geometric transformation and linear polarizations using six-fold-mirror geometry over the visible region.

The presence of optical rotation due to the Berry phase and coating-induced linear polarizations across a set of rays deteriorate the form of a point spread function. In this Letter, we model an optical system with six aluminum coated fold mirrors, and we show how to balance geometric transformation, linear retardance, and linear diattenuation simultaneously. We minimize the linear polarizations by arranging the six fold mirrors in three pairs of crossed-fold-mirror geometry.

A study of distribution of ABO and Rh (D) blood groups amongst Sikkimese.

The objective of this study was to find out the distribution pattern of ABO and Rh (D) blood groups in Sikkimese population of Gangtok as there is not a single report regarding this so far. Blood groups were studied in 142 healthy MBBS Sikkimese students of SMIMS, Gangtok of age group 19 to 24 years. Blood grouping was carried out by rapid slide test.

5-N-Substituted-2-(substituted benzenesulphonyl) glutamines as antitumor agents. Part II: synthesis, biological activity and QSAR study.

Cancer is a major killer disease throughout human history. Thus, cancer becomes a major point of interest in life science. It was proved that cancer is a nitrogen trap and tumor cells are avid glutamine consumers.
