We introduce the inertial cohomology ring NH * ,⋄ T (Y) of a stably almost complex man-ifold carrying an action of a torus T. We show that in the case that Y has a locally free action by T , the inertial cohomology ring is isomorphic to the Chen-Ruan orbifold cohomology ring H * CR (Y/T) (as defined in [Chen-Ruan]) of the quotient orbifold Y/T. For Y a(More)
We present a patient who collapsed with chest pain and dyspnoea on a transatlantic flight. She was found to have Pneumocystis carinii pneumonia (PCP) and human immunodeficiency virus infection. Platypnoea and orthodeoxia, which have not been previously reported in association with PCP, were major features of her illness. The PCP predominantly affected her(More)
Forty to fifty percent of colorectal cancer (CRC) patients develop colorectal liver metastases (CLM) that are either synchronous or metachronous in presentation. Clarifying whether there is a biological difference between the two groups of liver metastases or their primaries could have important clinical implications. A systematic review was performed using(More)
Neuroendocrine neoplasias (NEN) of the gastroenteropancreatic (GEP) system frequently present with metastatic deposits. The proliferation marker Ki-67 is used for diagnosis and to assess the prognosis of disease. The aim of our study was to evaluate the usefulness of Ki-67 % in the assessment of NEN patients with regard to their disease stage in clinical(More)
The optimum lymph node yield for tumour staging following surgery for rectal cancer remains controversial. This study aimed to determine the optimum number of lymph nodes needed to accurately determine stage III rectal cancer. Sixty-three thousand three hundred and eighty-one patients from the surveillance, epidemiology and end resulted database, who(More)
