Can brain electrical activity associated with the Craik-Cornsweet-O'Brien effect (CCOB) be identified in humans? Opposing luminance gradients met in the middle of a square image to create a luminance contrast-defined vertical border. The resulting rectangles on each side of the border were otherwise equiluminant, but appeared to differ in brightness, the CCOB effect. When the contrast gradients...

The ultrastructure of osteoclasts was examined in fetal rat bones after stimulation or inhibition of resorption in culture. A central ruffled border area completely encircled by a clear zone was considered to represent the resorbing system of the cell. The proportion of ruffled border and clear zone in osteoclast cross sections was compared with changes in bone resorption as measured by the rel...

Identification of regional myocardial ischemia by TQ-ST segment mapping, while commonly used, is relatively imprecise and nonspecific. In 41 open-chest dogs we examined whether monophasic action potentials (MAPs) recorded from the myocardial surface by means of a new contact-electrode technique could be used to more precisely and specifically index regional myocardial ischemia. After ligation o...

BACKGROUND Until recently onchocerciasis was prevalent in 37 out of 112 districts of Uganda with at least 3.8 million people at risk of contracting the disease, but following the launching of community-directed treatment with ivermectin (CDTI) in 1996 and the adoption of an onchocerciasis elimination policy in 2007, the country has made significant progress in combating the disease. By 2015, in...

using modern irrigation methods such as border irrigation is one way for an optimum usage of water. potato, for this study, was cultured in a farm located at kermanshah faculty of agriculture to evaluate the efficiency of border irrigation. the culture potato was the agria variety and the applied treatment were 50, 75, and 100 percent of potato plant`s water requirement. tapes were 12 m and the...

BACKGROUND Dengue is an emerging threat in the U.S.-Mexico border region. Transmission has regularly occurred in Sonora, MX since 1982 but it was not until 2014 that cities directly on the Arizona-Sonora border had local transmission. One of the closest urban areas to have regular seasonal transmission is Hermosillo, SN, MX. Developing a better understanding of the knowledge and perceptions of ...

OBJECTIVES Tuberculosis (TB) is a leading public health problem and a recognized priority for the federal Governments of both Mexico and the United States of America. The objectives of this research, primarily for the four states in the United States that are along the border with Mexico, were to: (1) describe the epidemiological situation of TB, (2) identify TB risk factors, and (3) discuss tu...

The World Health Organization (WHO) European region estimates that more than 400,000 tuberculosis (TB) cases occur in Europe, a large proportion of them among migrants. A coordinated public health mechanism to guarantee TB prevention, diagnosis, treatment and care across borders is not in place. A consensus paper describing the minimum package of cross-border TB control and care was prepared by...

The paper focuses on the tourism development strategy of the Amur Oblast called “Twin Cities”. Said initiative became the first attempt of the Russian Far Eastern regions to create the hospitality industry towards Chinese tourists in the Sino-Russian borderlands. Bringing together such sub-disciplines as border tourism, urban planning and territorial development helps to find out the peculiarit...
