Unified schemes of active galactic nuclei (AGNs) require an obscuring dusty torus around the central engine. The compact sizes (only a few parsecs) determined in recent high-resolution observations require that the obscuring matter be clumpy and located inside the region where the black hole gravity dominates over the galactic bulge. This location is in line with the scenario depicting the toru...

Life as a medical registrar presents many challenges and concern is growing that a downwards trend in recruitment to General Medicine is the direct result of a perception by junior doctors that the role of the medical registrar is excessively demanding and results in poor work-life balance. A solution-focused approach (SFA) can be used successfully to find a satisfying outcome for both registra...

In slow-growing Escherichia coli cells the chromosome is organized with its left (L) and right (R) arms lying separated in opposite halves of the nucleoid and with the origin (O) in-between, giving the pattern L-O-R. During replication one of the arms has to pass the other to obtain the same organization in the daughter cells: L-O-R L-O-R. To determine the movement of arms during segregation si...

A 10-year-old, spayed female, Maltese dog presented with a 2-day history of severe left eye squint. Slit-lamp biomicroscopy showed deep corneal defect stained into doughnut shape together hypopyon in the anterior chamber. Based on these results, diagnosis descemetocele and uveitis was made. Deep keratotomy combined nictitating membrane flap effectively resolved without complications. The surgic...
