Published: April 2021

Retinal arterial macroaneurysms (RAM) are characterized by a saccular or fusiform dilation of the retinal artery wall. An 84-year-old Caucasian woman with a medical history of poorly controlled hypertension was diagnosed with RAM in the left eye. Previous macular spectral-domain optical coherence tomography images from the patient were available for comparison. Near-infrared reflectance imaging (NIR-R), taken 3 years before, demonstrated a cuff-type thickening of the arteriolar vessel wall at the site of the current complicated RAM that had gone completely unnoticed. These findings suggest that NIR-R may contribute to the detection of early damage of the arterial wall that may predict arterial aneurysm formation in hypertensive patients.

Electronic address:

Water quality monitoring is one of the critical aspects of industrial wastewater treatment, which is important for checking the treatment effect, optimizing the treatment technology and ensuring that the water quality meets the standard. Chemical oxygen demand (COD) is a key indicator for monitoring water quality, which reflects the degree of organic matter pollution in water bodies. However, the current methods for determining COD values have drawbacks such as slow speed and complicated operation, which hardly meet the demand of online monitoring.

Increasing Cattle Herd Size or Density in C Grass-Legume Meadows Reduces Dietary Quality.

Animals (Basel)

January 2025

Graduate Program in Botany, Universidade Federal do Rio Grande do Sul, Porto Alegre 91540-000, Brazil.

Animal density is a grazing management decision implemented by managers that may reduce animal diet quality. Over three years, we collected herd-level cattle samples with varying animal numbers and densities across C grass-legume meadows near Powell, WY, USA. Paddocks ranged in size from 3 to 72 ha, cattle groups ranged from 80 to 370 animals, animal units (AUs; defined as heifers = 0.

Evaluation of genomic and phenomic prediction for application in apple breeding.

BMC Plant Biol

January 2025

Molecular Plant Breeding, Institute of Agricultural Sciences, ETH Zurich, Universitaetstrasse 2, Zurich, 8092, Switzerland.

Background: Apple breeding schemes can be improved by using genomic prediction models to forecast the performance of breeding material. The predictive ability of these models depends on factors like trait genetic architecture, training set size, relatedness of the selected material to the training set, and the validation method used. Alternative genotyping methods such as RADseq and complementary data from near-infrared spectroscopy could help improve the cost-effectiveness of genomic prediction.

Food properties modulate activities in posterior parietal and visual cortex during chewing.

Department of Anesthesiology, Nihon University School of Dentistry at Matsudo, 2-870-1 Sakaecho-Nishi, Matsudo, Chiba, 271-8587, Japan. Electronic address:

Cross-modal interactions between sensory modalities may be necessary for recognition of chewing food by the invisible oral cavity to avoid damaging the tongue and/or oral mucosa. The present study used functional near-infrared spectroscopy to investigate whether the food properties hardness and size influence activities in the posterior parietal cortex and visual cortex during chewing performance in healthy individuals. It was found that an increase in food hardness enhanced both posterior parietal cortex and visual cortex activities, while an increase in food size enhanced activities in the same regions.
