The periplasmic PapD-like chaperones have long been known to be necessary for the assembly of bacterial surface organelles. New structural work now suggests that they control assembly by arresting subunit folding. This step may be required to preserve energy for fiber formation.

Three cases are reported in which angiographic embolisation therapy was effective in arresting upper gastrointestinal bleeding secondary to metastatic hypernephroma. Each patient had histologically confirmed disseminated renal cell carcinoma and presented with recurrent haematemeses with a successful outcome following palliative embolisation therapy.

Status epilepticus is a medical emergency requiring immediate treatment. General treatment is aimed at restoring physiologic homeostasis, and drug therapy is aimed at arresting the convulsive activity and preventing its recurrence. Concurrent administration of diazepam and either phenytoin or phenobarbital will be effective in most cases. After the status epilepticus has been treated the underl...

We investigate the process of slow intergranular crack propagation by the finite element method model and show that branching is induced by partial arresting of a crack front owing to the geometrical randomness of grain boundaries. A possible scenario for the branching instability of crack propagation in a disordered continuous medium is also discussed.

The ongoing Syrian Civil War is one of the most arresting issues in international area 21st century.
