Exopolysaccharide is detrimental for the symbiotic performance of Sinorhizobium fredii HH103 mutants with a truncated lipopolysaccharide core.

The nitrogen-fixing rhizobia-legume symbiosis relies on a complex interchange of molecular signals between the two partners during the whole interaction. On the bacterial side, different surface polysaccharides, such as lipopolysaccharide (LPS) and exopolysaccharide (EPS), might play important roles for the success of the interaction. In a previous work we studied two Sinorhizobium fredii HH103 mutants affected in the rkpK and lpsL genes, which are responsible for the production of glucuronic acid and galacturonic acid, respectively.

Violence against healthcare workers during the phases of the COVID-19 Pandemic: a descriptive observational study from 2018 to 2023 in the metropolitan city of Genoa (North-Western Italy).

Background: Violence against healthcare workers is an escalating public health concern, affecting the quality of care, and causing significant psychological and physical effects on healthcare professionals. This study analysed the trend in aggressions in healthcare settings in the pre-pandemic, pandemic, and post-pandemic periods.

Methods: An observational descriptive study was conducted to analyse reports of violence against healthcare workers from January 2018 to June 2023 at a Local Health Authority "ASL3" in the Liguria region of Italy.

Technological interventions in European dementia care: a systematic review of acceptance and attitudes among people living with dementia, caregivers, and healthcare workers.

Background: Alzheimer's and other neurodegenerative forms of dementia affect 8 million Europeans. Assistive technologies are suggested to reduce the burden of care and improve the quality of life of person living with dementia. Nonetheless, the acceptance and attitudes toward technological interventions pose challenges not only for people living with dementia and caregivers but also for healthcare workers.

Bucking the trend: understanding lipopolysaccharide structure and outer membrane dynamics in cold-adapted isolated from Enigma Lake, Antarctica.

Cold environments are predominant over the Earth and are inhabited by bacteria able to cope with a series of simultaneous environmental pressures. Gram-negative species of the genus are the predominant ones isolated from cold habitats, making them an excellent model for studying the mechanisms of bacterial adaptation to the most extreme habitats on our planet. Here we focused on the lipopolysaccharide (LPS) structure and the outer membrane dynamics of sp.
