[Use of Artificial Intelligence in Diabetic Retinopathy Screening: Experience in a Health Service in Santiago, Chile].

Unlabelled: Early detection of diabetic retinopathy is critical for preventing vision loss.

Aim: To evaluate the use of artificial intelligence (AI) for screening sight threatening diabetic retinopathy (DR) in a public Hospital in Chile.

Material And Methods: The mydriatic retinal photographs of 366 participants were uploaded for analysis by EyeArt, a cloud-based AI software developed by Eyenuk (Los Ángeles, USA).

Full moon mesencephalon sign: a transient cytotoxic lesion in a hemodialysis patient with newly diagnosed atrial fibrillation and severe stenosis of the right vertebral artery.

Brain cytotoxic edema is a neuroradiological sign secondary to variegate diseases ranging from migraine to fulminant Listeria rhombencephalitis. The tempestive identification of its underlying cause is vital for an effective treatment as any delay may be fatal. However, the lack of distinctive imaging biomarkers and the paucity of reports pose a significant challenge in its diagnosis and frequently lead to a misdiagnosis particularly with the more common acute ischemic stroke.

Antimicrobial properties of the essential oil of Schinus areira (Aguaribay) against planktonic cells and biofilms of S. aureus.

The essential oil (EO) of Schinus areira L. (Anacardiaceae) leaves has shown antibacterial activity against Staphylococcus aureus. In this study, we aimed to unravel the mechanisms of its antibacterial action by using bacterial cells and model membranes.

Prediction of tenderness in bovine longissimus thoracis et lumborum muscles using Raman spectroscopy.

Objective: This study was conducted to evaluate Raman spectroscopy technique as a noninvasive tool to predict meat quality traits on Braford longissimus thoracis et lumborum muscle.

Methods: Thirty samples of muscle from Braford steers were analyzed by classical meat quality techniques and by Raman spectroscopy with 785 nm laser excitation. Water holding capacity (WHC), intramuscular fat content (IMF), cooking loss (CL), and texture profile analysis recording hardness, cohesiveness, and chewiness were determined, along with fiber diameter and sarcomere length by scanning electron microscopy.
