Published: July 2012

The study aimed to investigate baroreceptor reflex sensitivity in a patient with head injury for whom plateau waves of intracranial pressure (ICP) were recorded. Baroreflex sensitivity index was separately estimated on top of plateau waves and during intermediate intervals between two consecutive waves. The EuroBaVar data set was utilized to verify and validate the results. A very high baroreflex sensitivity associated with dominant parasympathetic activity was observed spontaneous to the acute elevations of ICP. The high vagal afferent discharge was found to be suggestive for the high firing rate of carotid baroreceptors and probably an active Cushing reflex mechanism during plateau waves.

Background: During the COVID-19 pandemic, hospitals were overwhelmed with infected patients, leading to a disruption in the delivery of services. Patients with cancer, including breast cancer, rely on timely treatment, as delays can reduce survival rates. In this study, we investigated delays in treatment and the factors contributing to delays in chemotherapy and radiotherapy for these patients.

Aim: To describe the use of invasive mechanical ventilation core strategies, adjuvant treatments and the occurrence of barotrauma and prolonged ventilation in ICU patients with COVID-19 in Denmark, retrospectively.

Methods: All ICUs admitting COVID-19 patients in Denmark from 10 March 2020 to 2 April 2021 were invited to participate. All patients with COVID-19 who received invasive mechanical ventilation were included and data was retrospectively collected from electronic patient records.

Dental implant coronal surfaces designed with the primary goal of maintaining crestal bone levels may also promote bacterial adhesion, leading to soft tissue inflammation and peri-implant bone loss. Achieving an optimal surface roughness that minimizes bacterial adhesion while preserving crestal bone is crucial. It is hypothesized that a specific threshold surface roughness value may exist below which, and above which, initial bacterial adhesion does not statistically change.

Influence of cell shape on sonoporation efficiency in microbubble-facilitated delivery using micropatterned cell arrays.

Microbubble-facilitated sonoporation is a rapid, versatile, and non-viral intracellular delivery technique with potential for clinical and ex vivo cell engineering applications. We developed a micropatterning-based approach to investigate the impact of cell shape on sonoporation efficacy. Cationic microbubbles were employed to enhance sonoporation by binding to the cell membrane electrostatically.

This work assessed the efficiency and sustainability of ultrasound-assisted extraction (UAE) of anthocyanins from grape pomace using bio-based solvents: Ethanol, Isopropanol, Propylene-glycol, and Ethylene-glycol at different concentrations (50 and 100 % v/v) and temperatures (25 °C and 50 °C). Higher ultrasonic intensities (UI) were obtained at 50 °C and 50 % v/v by decreasing solvents viscosities. Under these conditions, anthocyanin extractions were performed with different combinations of solvent to liquid ratio (SLR) at 1:10 and 1:50 g/mL, and UI (3.
