The Meaning of Inchoative se in Brazilian Portuguese: A Replication of Lundquist et al.'s (2016) Experiment.

In the well-known causative alternation, a verb appears either in a causative-transitive or in an inchoative-intransitive form. The inchoative form is marked with a reflexive clitic in some languages, such as Norwegian, but is unmarked in others, such as English. There are two main proposals to explain the alternation: a lexical-derivational account (a lexical rule is responsible for the demotion of the cause argument), and a syntactic-derivational one (in a type of reflexivization, the theme/patient is construed as responsible for causing the event).

Longitudinal Study of Plasma Visfatin/Nicotinamide Phosphoribosyltransferase (NAMPT) Levels in Healthy Pregnant Women.

Visfatin/nicotinamide phosphorybosil transferase (NAMPT) is a novel adipocytokine with potential roles in the pathophysiology of metabolic disorders, including gestational disorders. However, there is no clear interpretation regarding the circulating visfatin levels in a healthy pregnancy. Therefore, we conducted the first longitudinal study of plasma visfatin levels that followed up healthy pregnant women until the third trimester, including the postpartum period (PPP).

Exogenous surfactant reduces inflammation and redox imbalance in rats under prone or supine mechanical ventilation.

Mechanical ventilation (MV) is a lifesaving therapy for patients with acute or chronic respiratory failure. Despite, it can also cause lung injury by inducing or worsening inflammatory responses and oxidative stress. Several clinical approaches have protective effects on the lungs, including the prone position and exogenous surfactant; however, few studies have evaluated the association between the two strategies, especially in individuals without previous lung injury.
