Immunological parameters were measured in order to elucidate a postoperative immunosuppression mechanism in transthoracic esophagectomy for patients with esophageal cancer. Moreover, lymphokine-activated killer (LAK) cells were transferred just after the surgery to overcome the postoperative immunosuppression. Fifteen consecutive patients who underwent transthoracic esophagectomy were subjected...

Despite the size and importance of separately managed accounts (SMAs) and collective investment trusts, their characteristics and performance have not been studied in detail. We show that separate account performance is similar to that of index funds and superior to that of actively managed mutual funds. Management supplies a benchmark for each separate account. When the management-selected ben...

The interpretation generated from a sentence of the form P and Q can often be different to that generated by Q and P, despite the fact that and has a symmetric truth-conditional meaning. We experimentally investigated to what extent this difference in meaning is due to the connective and and to what extent it is due to order of mention of the events in the sentence. In three experiments, we col...

Sarcoidosis is a multisystemic granulomatous disorder of unknown aetiology typically affecting the lungs and lymph nodes. Less frequently, the kidneys may also be affected. Postmortem analysis suggests that 20 percent of patients have histologic changes in the kidney. However, clinical involvement of the kidney is a relatively uncommon condition. Renal failure may occur associated with hypercal...

We present a 57-year-old male chronic haemodialysis patient with a giant umbilical hernia. After two months on dialysis, incarceration of the hernia with partial intestinal obstruction occurred, and this led to severe hypoproteinaemia secondary to protein-losing enteropathy, caused by increased lymphatic pressure. These problems were resolved following surgical repair of the hernia. There are f...

Background: Despite thousands of publications over the past 90 years on the assessment of teaching effectiveness, there is still confusion, misunderstanding, and hand-to-hand combat on several topics that seem to pop up over and over again on listservs, blogs, articles, books, and medical education/teaching conference programs. If you are measuring teaching performance in face-to-face, blended/...

In a more and more regulated and socially pressured environment, the durable management of winery effluents must take into account their characteristics and their potential impact on their natural setting. The object of this exploratory study is to establish an inventory of the microbiological composition of winery effluents coming from different treatment systems. We have observed that winery ...
