A combination of density functional and dynamical mean field theory calculations are used to show that the remarkable metal-insulator transition in the rare-earth-element nickelate perovskites arises from a site-selective Mott phase, in which the d electrons on half of the Ni ions are localized to form a fluctuating moment while the d electrons on other Ni ions form a singlet with holes on the ...

Fig. 1 and Fig. 2 : Lipoatrophy over the left para-umbilical region. A 59-year-old male with type 2 diabetes of 19 years duration had been treated with premixed recombinant human insulin (30% regular and 70% NPH) for the last 18 months. He was injecting himself predominantly over the left side of the abdomen. He developed subcutaneous lipoatrophy around the injection site about 14 months after ...

osteoblastoma is a rare benign, but locally aggressive bone tumor with rare malignant transformation. it mostly affects the vertebral column and long bones. radiographically, it is seen as an expansile, oval, sclerotic or lytic mass-like lesion with well-defined borders, although sometimes it may mimic a malignant tumor such as osteogenic sarcoma by its irregular borders. herein, we report a ca...

thisis a case report of a 24-year-old man who presented with increased pain and firm swelling of the right foot after a minor twisting injury. radiography, computed tomography (ct) and magnetic resonance imaging (mri) findings showed ancillary information that was helpful for surgical treatment. the final diagnosis was confirmed aschondroblastoma of the navicular bone based on the pathology rep...

mycotic pseudoaneurysm of the ascending aorta is rare in patients undergoing coronary artery bypass graft (cabg) and usually caused by staphylococcus aureus. we describe a patient with a mycotic pseudoaneurysm of the ascending aorta at the proximal vein graft anastomosis site after cabg. culture from the sinus tract of the sternum and from the aneurysm sac was klebsiella pneumoniae. surgical te...

The 5 mm trocar-site hernia are very rare complication of laparoscopic surgery and surgeons usually avoid fascial closure at trocar-site. We show a case anterior rectomeshplasty with early omental herniation through surgical repair, as well an advice on whether or not to undertake the
