With worldwide concern over the use of antibiotics in animal agriculture and their contribution to the spread of antibiotic resistance, alternatives to conventional antibiotics are needed. Previous research in our laboratories has shown that colicin E1 is effective against some Escherichia coli strains responsible for postweaning diarrhea (PWD) in vitro. In this study we examined the efficacy o...

This review focuses on the diagnostic value of hybrid F18-FDG Positron Emission Tomography/Computerized tomography (PET/CT) in fever of unknown origin (FUO) and inflammation of unknown origin (IUO). Due to the wide range of possible causes both FUO and IUO remain a clinical challenge for both patients and physicians. In addition, the aetiology of IUO shows the same variation in diseases as the ...

This paper compares emission taxes with other taxes from the viewpoint of emission reduction in an open economy. Using a simple monopoly model, we show that emission taxes may not be very effective to protect environment because of the spillover effects between markets stemming from non-constant marginal costs and transboundary externalities. Other taxes such as production taxes and tariffs are...

We consider whether pollution-intensive FDI tends to outflow from a country which maintains stringent environmental regulations and into countries with weak environmental regulations. We consider this issue by incorporating the predictions from the recent heterogeneous firm models of international trade into an empirical model of outward FDI by UK firms. We find that environmental regulations a...

This article reviews the performance of the World Trade Organization in the oversight of national regulatory decisions affecting agricultural and food trade. A picture emerges of modest international disciplines on the regulatory decisions of sovereign nations and the need for ongoing improvements. A road map to regulations is presented and empirical assessments of the effects of technical regu...

Recent papers show that imperfect property rights to a natural resource–a sector-specific factor– can be a source of comparative advantage. In these models, weaker property rights attract labor–the only mobile factor– to the resource sector, increasing the country’s comparative advantage for that sector. If capital in addition to labor is mobile, and if the benefits of capital are non-excludabl...

Insulin receptor substrate 1 (IRS-1) is a major substrate of insulin, insulin-like growth factors, and cytokine signaling and plays an important role in mediating apoptosis, cell differentiation, and cell transformation. We found that IRS-1 is constitutively activated in a variety of solid tumors, including breast cancers, leiomyomas, Wilms' tumors, rhabdomyosarcomas, liposarcomas, leiomyosarco...

Extramedullary plasmacytoma is rare in patients with diagnosed multiple myeloma. Soft tissue plasmacytoma of the gallbladder is particularly uncommon and has been described in only a handful of cases. Diagnosis of gallbladder plasmacytoma with fluorine 18-fluorodeoxyglucose (F18-FDG) positron emission tomography/computed tomography (PET/CT) has not previously been reported. We present a 65-year...

A country with a surplus river basin cooperates with a country with a deficit river basin in a joint investment project to build a water canal. The benefits from the existence of the canal are realized when cooperation halts and countries will have the opportunity to engage in a non-cooperative water market game. We define an imputation distribution procedure to share the “burden” from cooperat...

A 69-year-old woman was diagnosed with stage IIIA advanced Type IV Klatskin cholangiocarcinoma, which was treated with radical choledochectomy, extended right hepatectomy and left hepaticojejunostomy. About six months after surgery, she presented with painless jaundice. A 2-18F-fluoro-2-deoxy-D-glucose positron emission tomography-computed tomography (F18-FDG PET-CT) was performed, which detect...
