Long-Term Disabilities in ICU Survivors of COVID-19.

Background: COVID-19 is associated with prolonged disability, particularly after critical illness. This study aimed to assess and compare disability post-hospital discharge of subjects who were invasively ventilated versus those who were not, following ICU admission due to COVID-19. This study also explored variables associated with long-term disability.

Substrate-Controlled Bidirectional Pumping by a Bienzymatic Micropump.

The development of autonomous, miniaturized pumps remains a problem of much interest, particularly with a view on microfluidics-based devices with increased portability and simplicity of use by nonspecialists. Spatially localized patches of enzyme imprinted on walls have been shown to induce a hydrodynamic flow when supplied with the corresponding enzyme substrate. Thus, such enzymatic micropumps are seen as a possible way of providing the means for nonmechanical, structurally simple, autonomous pumping.

Adaptation of the normative rating procedure for the International Affective Picture System to a remote format.

Background: The Self-Assessment Manikin (SAM), a pictorial scale for the measurement of pleasure and arousal dimensions of emotions, is one of the most applied tools in the emotion research field.

Objective: We present a detailed description of a remote method to collect affective ratings in response to pictures by using the SAM scale.

Methods: To empirically validate our remote method, we conducted a study using a digitized version of the SAM scale and delivered online didactic instructions that followed the normative rating procedure for the International Affective Picture System (IAPS) to the participants.

Current clinical framework on nitric oxide role in periodontal disease and blood pressure.

Objectives: In this review, we explored potential associations between NO and its derivatives, nitrite and nitrate, with periodontal and cardiovascular diseases, with special emphasis on the former. By providing a state-of-the-art and integrative understanding of this topic, we aimed to shed light on the potential role of these three nitrogen oxides in the periodontitis-hypertension nexus, identify knowledge gaps, and point out critical aspects of the experimental methodologies.

Materials And Methods: A comprehensive literature review was conducted on human salivary and plasma concentrations of nitrate and nitrite, and their impact on periodontal and cardiovascular health.

Lipid Fraction from as a Potential Therapeutic Agent for Lethal Sepsis in Mice.

Sepsis is a potentially fatal clinical condition that results from an immune imbalance in the host during an infection. It presents systemic alterations due to excessive activation of pro-inflammatory mediators that contribute to inflammation, formation of reactive species, and tissue damage. Anti-inflammatory mediators are then extensively activated to regulate this process, leading to immune exhaustion and, consequently, immunosuppression of the host.
