HIV-1 entry into cells is mediated by interactions between the envelope (Env) gp120 and gp41 proteins with CD4 and chemokine receptors via an intermediate called the viral fusion complex (vFC). Here, mAbs were used to find the dynamic changes in expression of antigenic epitopes during vFC formation. A CD4-specific mAb (R275) and anti-vFC mAbs, designated F12-1, F13-6 and F18-4 that recognize th...

In order not to see their climate mitigation efforts be in vain by the unlimited growth in China and India, the developed world has started to consider imposing border tax adjustments on imports from these fast developing countries. This paper puts this problem into a game-theoretic perspective. It sets up the problem as a game between the developed world deciding on three regimes of border tax...

This study compares alternative measures of the potential and actual pollution content of China’s trade using an environmental I-O methodology. Using the conventional, potential measure adopted by other researchers, we find that China ‘saves’ on local environmental resources by exporting goods that on average embody less pollution content than imports would if they were produced locally in Chin...

Post-weaning diarrhea (PWD) and edema disease (ED), caused by enterotoxigenic Shiga toxin producing Escherichia coli (ETEC STEC) strains, are important diseases of newly weaned piglets worldwide. The objective this study is to develop a passive immunization strategy protect against PWD ED using recombinant Lactococcus lactis added piglet diet at weaning. Variable Heavy chain domains antibodies ...

Converging evidence implicates the dopaminergic system and the prefrontal and nigrostriatal regions in the pathophysiology of attention deficit hyperactivity disorder (ADHD). Using positron emission tomography (PET) with [fluorine-18]fluorodopa (F18-DOPA), we compared the integrity of the presynaptic dopaminergic function between 17 ADHD adults and 23 healthy controls. The ratio of the isotope ...

Identification of Escherichia coli causing porcine postweaning diarrhea requires knowledge regarding the prevalent pathotypes within a given region. A total of 100 Escherichia coli isolates from piglets with diarrhea in Londrina city, Parana State, South Brazil, were screened for the presence of genes for F4, F5, F6, F18, F41 fimbrial antigens by specific probes and for enterotoxins (STa, STb, ...

the effect of economic growth and free trade on environment and transnational pollutions is one of the most important current discussions in the field of environmental economics. nowadays, the economics, social and developmental consequences of the climatic changes around the world is increasingly accepted and approved. in fact, the environment is considered as one of the key elements for susta...

This paper proposes a novel method to designing an H ∞ PID controller with robust stability and disturbance attenuation. This method uses particle swarm optimization algorithm to minimize a cost function subject to H ∞ -norm to design robust performance PID controller. We propose two cost functions to design of a multiple-input, multiple-output (MIMO) and single-input, single-output (SISO) robu...

This paper investigates how the environmental pollution in East Asian countries can be affected by trade of ‘dirty’ goods with Japan and the USA. By controlling for trade openness, the share of manufacturing in GDP, and the trade of pollution-intensive products with Japan and the USA, CO2 emissions are estimated for ten East Asian countries between 1988 and 2000. Our results show that increasin...

Contrast PET/CT may show layering within the UB, and several examples of have been reported in literature. But without using contrast this is rare. Our case demonstrates interesting posterior F18-FDG urinary bladder a 78 years old male use contrast.
