Coupling the thermal acoustic modes of a bubble to an optomechanical sensor.

Optomechanical sensors provide a platform for probing acoustic/vibrational properties at the micro-scale. Here, we used cavity optomechanical sensors to interrogate the acoustic environment of adjacent air bubbles in water. We report experimental observations of the volume acoustic modes of these bubbles, including both the fundamental Minnaert breathing mode and a family of higher-order modes extending into the megahertz frequency range.

Unveiling the Virulence Mechanism of Leptosphaeria maculans in the Brassica napus Interaction: The Key Role of Sirodesmin PL in Cell Death Induction.

Leptosphaeria maculans is the causal agent of blackleg disease in Brassica napus, leading to substantial yield losses. Sirodesmin PL, the principal toxin produced by L. maculans, has been implicated in the infective process in plants.

Impact of Bariatric Surgery on the Quality of Life of Obese Individuals with Chronic Low Back Pain.

Introduction: Obesity has been increasing at alarming rates in Brazil and worldwide. It is known that bariatric surgery is an effective and safe treatment for severely obese adults with related comorbidities or morbidly obese individuals. Among the various comorbidities, chronic low back pain is one of the major sources of discomfort and reduced quality of life in these patients.

Contextual barriers to infection prevention and control program implementation in hospitals in Latin America: a mixed methods evaluation.

Background: Infection prevention and control (IPC) programs are essential to prevent and control the spread of multidrug-resistant organisms in healthcare facilities (HCFs). The current implementation of these programs in Latin America remains largely unknown.

Methods: We conducted a mixed-methods evaluation of IPC program implementation in HCFs from Guatemala, Panama, Ecuador, and Argentina, March-July 2022.
