AI Article Synopsis
Article Abstract
An extension of the white light spatial-phase-shift (WLSPS) for object surface measurements is described. Using WLSPS, surface measurements can be obtained from any real object image without the need of a reference beam, thus achieving inherent vibration cancellation. The surface topography is obtained by acquiring multiple images of an object illuminated by a spectrally modulated white light source and using an appropriate algorithm. The modulation of the light source obviates the need for the continuous phase delay to obtain the interferograms.

Race, homosexuality, and AIDS in London: the response of British AIDS voluntary organizations to Black gay men's sexual health needs during the AIDS crisis (1980s-2000).
Mod Br Hist

Focusing on three specific organizations-The Terrence Higgins Trust (THT), Blackliners, and The NAZ Project (Naz)-this article explores the different ways in which voluntary organizations responded to Black gay men (BGM) in Britain during the AIDS crisis from the 1980s to 2000. Illustrating how the place of BGM in Britain at this time was multidimensional and often contradictory, the first section demonstrates how they required safer-sex messaging that took account of the heterogeneous ways in which they experienced the intersection of racism and homophobia. Situated in this context, the second section explores for the first time the well-documented work of THT as it applied to BGM.

Induction of systemic acquired resistance (SAR) in plants to control bacterial diseases has become an effective solution to the problems of agrochemical resistance and ecological environment damage caused by long-term and large-scale use of traditional bactericides. However, current SAR-inducing compounds are often unable to rapidly eliminate pathogenic bacteria in infected plant tissues to prevent further spread of the disease, severely restraining the potential for extensive application in agriculture. Herein, we address the limitations by developing a series of visible-light-absorbing aggregation-induced emission photosensitizers suitable for agricultural use.

Description: Gastric cancer (GC) is a leading cause of preventable cancer and mortality in certain US populations. The most impactful way to reduce GC mortality is via primary prevention, namely Helicobacter pylori eradication, and secondary prevention, namely endoscopic screening and surveillance of precancerous conditions, such as gastric intestinal metaplasia (GIM). An emerging body of evidence supports the possible impact of these strategies on GC incidence and mortality in identifiable high-risk populations in the United States.

Objective: Aim: To determine the effect of cell therapy on the intensity of lipid peroxidation processes in the liver, kidneys and lungs of rats of different ages under conditions of experimental cranio-skeletal trauma (CST).
Patients And Methods: Materials and Methods: In the experiments, 129 white male Wistar line rats of different age groups were used: immature rats aged 100-120 days and weighing 90-110 g; mature rats aged 6-8 months and weighing 180-200 g; and old rats aged 19-23 months and weighing 300-320 g. In each age group, CST was modeled under thiopental sodium anesthesia.
Stepwise Modulation of Bridged Single-Benzene-Based Fluorophores for Materials Science.
Chemistry
December 2024
Universitat Duisburg-Essen, Institute of organic chemistry, Universitätsstraße 7, 45117, Essen, GERMANY.
In recent years, researchers studying fluorogenic samples have steadily shifted from using large, expensive, poorly soluble fluorophores with complex synthetic sequences to smaller, simpler p scaffolds with low molecular weight. This research article presents an in-depth study of the photophysical properties of five bridged single-benzene-based fluorophores (SBBFs) investigated for their solution and solid-state emission (SSSE) properties. The compounds O4, N1O3, N2O2, N3O1, and N4 are derived from a central terephthalonitrile core and vary in the amount of oxygen and nitrogen bridging atoms.
