Assessment of ocular blood flow using laser based instruments is a rapidly emerging area of ophthalmic diagnosis. In this article, six specific laser based instruments are described and compared in terms of appropriate target vasculature and measured hemodynamic parameters. Described are retinal laser Doppler instruments, laser Doppler instruments for assessment of the optic nerve head microcirculation, and laser speckle instruments. © 1998 Society of Photo-Optical Instrumentation Engineers.

Background: The conventional lymphocyte crossmatch (XM) assay necessitates mononuclear cell isolation. In our previous work, we introduced a novel 3-laser, 4-color flow cytometric (FC) XM protocol utilizing whole blood lysis (WBL) and CD45 fluorescence-triggered acquisition to detect human leukocyte antigen (HLA) antibody binding. Building on this, we aimed to adapt these advancements for complement-dependent cytotoxicity (CDC) XM using FC (FCCDC).

This study explores the effects of steaming, roasting, and steam explosion treatment on the structural, rheological, and functional properties of whole grain oat flour, with a particular focus on starch changes and starch-protein interactions. Steam explosion treatment altered the physicochemical properties of whole grain oat flour, evidenced by changes in color parameters (L* from 70.9 to 67.

Additively manufactured biodegradable metals demonstrate great potential in orthopedic implants, enabling patient-specific designs and eliminating the need for secondary surgeries through degradation. Zinc (Zn)-magnesium (Mg) alloys reconcile the dilemma between Zn's low biological activity and Mg's rapid degradation, and become promising bone-repair materials. However, Zn-Mg alloys currently fabricated via additive manufacturing exhibit high strength but low ductility, and the effects and mechanisms by which Mg influences their degradation and bone regeneration remain unclear and debated.

The phenomena of thermochromic afterglow have attracted significant attention in advanced information encryption and anticounterfeiting applications. However, it is still a challenge to realize visible light-activated thermochromic afterglow in a single material. Herein, we demonstrate thermochromic afterglow under visible light excitation in a novel carbon dot (CD)-based composite, utilizing a temperature-dependent dual-mode afterglow mechanism.

A vast amount of plastic waste enters the ocean every year and the Mediterranean Sea is particularly affected by this issue. Biodegradable polymers like poly(lactic acid) (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), may help mitigate this problem. We investigated bacterial biofilm development and succession on these polymers over one year in the Western Mediterranean Sea.
