Diagnosis and management of superficial arteriovenous malformations: French healthcare network's recommendations.

Superficial arteriovenous malformations are rare fast-flow lesions. They consist of arteriovenous shunts, without cellular hyperplasia or proliferation, which develop in the surrounding tissues (cutaneous, subcutaneous, muscular, bone). Although benign, they are among the most severe of superficial malformations.

Nucleoporin Nsp1 surveils the phase state of FG-Nups.

Transport through the nuclear pore complex (NPC) relies on intrinsically disordered FG-nucleoporins (FG-Nups) forming a selective barrier. Away from the NPC, FG-Nups readily form condensates and aggregates, and we address how this behavior is surveilled in cells. FG-Nups, including Nsp1, together with the nuclear transport receptor Kap95, form a native daughter cell-specific cytosolic condensate in yeast.

Management and outcomes of pregnant women with cardiovascular diseases in a cardio-obstetric team.

Background: Cardiovascular diseases (CVDs) are currently the leading cause of maternal death in Western countries. Although multidisciplinary cardio-obstetric teams are recommended to improve the management of pregnant women with CVD, data supporting this approach are scarce.

Aims: To describe the characteristics and outcomes of pregnant patients with CVD managed within the cardio-obstetric programme of a tertiary centre.

Optimized protocols for RNA interference in Macrostomum lignano.

Macrostomum lignano, a marine free-living flatworm, has emerged as a potent invertebrate model in developmental biology for studying stem cells, germline, and regeneration processes. In recent years, many tools have been developed to manipulate this worm and to facilitate genetic modification. RNA interference is currently the most accessible and direct technique to investigate gene functions.

A physicochemical perspective on cellular ageing.

Cellular ageing described at the molecular level is a multifactorial process that leads to a spectrum of ageing trajectories. There has been recent discussion about whether a decline in physicochemical homeostasis causes aberrant phase transitions, which are a driver of ageing. Indeed, the function of all biological macromolecules, regardless of their participation in biomolecular condensates, depends on parameters such as pH, crowding, and redox state.
