Liquid-liquid phase separation of various transcription factors into biomolecular condensates plays an essential role in gene regulation. Here, using cellular models and in vitro studies, we show the spatiotemporal formation and material properties of p53 condensates that might dictate its function. In particular, p53 forms liquid-like condensates in the nucleus of cells, which can bind to DNA and perform transcriptional activity.

Here, we introduce a new class of amyloid fibril-based peptide hydrogels as a versatile biomimetic ECM scaffold for 3D cell culture and homogenous tumor spheroid modeling. We show that these amyloid fibril-based hydrogels are thixotropic and allow cancer cell adhesion, proliferation, and migration.

The clavicle fractures managed non-operatively have shown a high prevalence of symptomatic malunion and non-union. We sought to compare patient-oriented outcome and complication rates following non-operative treatment and those after operative treatment of clavicular fractures. In a prospective randomised study, 30 patients with 30 clavicle fractures were randomised by systemic allocation to either operative treatment or non-operative treatment.

Recent studies suggest in this technique graft is placed in non-anatomical position leading to instability. If the femoral tunnel is drilled through an anteromedial portal (transportal technique), graft can be placed more anatomically leading to better knee stability theoratically.
