The HmrABCX pathway regulates the transition between motile and sessile lifestyles in by a mechanism independent of transcription.

Unlabelled: During its cell cycle, the bacterium switches from a motile, free-living state, to a sessile surface-attached cell. During this coordinated process, cells undergo irreversible morphological changes, such as shedding of their polar flagellum and synthesis of an adhesive holdfast at the same pole. In this work, we used genetic screens to identify genes involved in the regulation of the transition from the motile to the sessile lifestyle.

How Do Nursing Students Perceive Moral Distress? An Interpretative Phenomenological Study.

Background: Research shows that the longer nurses care for terminally ill patients, the greater they experience moral distress. The same applies to nursing students. This study aims to analyze episodes of moral distress experienced by nursing students during end-of-life care of onco-hematologic patients in hospital settings.

eDNA-stimulated cell dispersion from biofilms upon oxygen limitation is dependent on a toxin-antitoxin system.

In their natural environment, most bacteria preferentially live as complex surface-attached multicellular colonies called biofilms. Biofilms begin with a few cells adhering to a surface, where they multiply to form a mature colony. When conditions deteriorate, cells can leave the biofilm.

Prevalence and types of video gaming and gambling activities among adolescent public school students: findings from a cross-sectional study in Italy.

Adolescence is characterized by emotional instability and risk-taking behaviours that can lead to, among other things, an increased risk of developing pathological video-gaming and gambling habits. The aim of this Study is to assess the prevalence and type of video gaming and gambling habits in adolescent students attending Italian upper-secondary schools. The cross-sectional study was conducted via an online survey using validated questionnaires.
