The leukocyte adhesion molecule L-selectin mediates neutrophil adhesive interactions with endothelial cells and is in part responsible for neutrophil rolling. We examined the role of L-selectin in ischemia-reperfusion injury of rabbit ears using a monoclonal antibody (MoAb) directed to a functional epitope of L-selectin. Arterial blood flow to the rabbit ear was occluded for six hours with ambi...

The presence within the epithelioid granulomas of sarcoidosis of lymphocytes of the "helper" (T4 positive) phenotype suggests that, as in granulomatous diseases of known aetiology, active cell mediated immunity plays a part in the disease. It has, however, been noted that T8 positive lymphocytes are also found on occasion in the granulomas. The presence of cells bearing markers associated with ...

The role of LAM1 in dorsoventrality and lateral growth of the leaf blade was investigated in the 'bladeless' lam1 mutant of Nicotiana sylvestris and in periclinal chimeras with lam1 and wild-type (N. glauca) cell layers. Mutant lam1 primordia show normal dorsoventrality at emergence, but produce blade tissue that lacks dorsal cell types and fails to expand in the lateral plane. In leaves of a l...

Today’s credit card issuers are increasingly offering a broad range of products and services with separate lines of business responsible for different product groups. Too often, the separate lines of business operate independently and information available to one line of business may not be used productively by others. In this study, we examine the potential of using information from customers ...

We have analyzed the statistical probabilities of limit-order book (LOB) shape through building the book using the ultra-high-frequency data from 23 liquid stocks traded on the Shenzhen Stock Exchange in 2003. We find that the averaged LOB shape has a maximum away from the same best price for both buy and sell LOBs. The LOB shape function has nice exponential form in the right tail. The buy LOB...

This study investigates the daily dynamic relation between returns and institutional and individual trades in the TAIEX futures market. I find that both past individual and institutional buys and sells have no predictive power for index returns; both individual and institutional trading activities are strongly related to their own past trades, and individual open-buy trading is also influenced ...
