Within the mammalian testis, specialized tight junctions between somatic Sertoli cells create basal and apical polarity within the cells, restrict movement of molecules between cells, and separate the seminiferous epithelium into basal and adluminal compartments. These tight junctions form the basis of the blood-testis barrier, a structure whose function(More)
Nicotine and some related alkaloids in tobacco and tobacco wastes are harmful to health and the environment, and a major environmental requirement is to remove them from tobacco and tobacco wastes. In this study, an isolated strain, S16, identified as Pseudomonas putida biotype A, was used to investigate nicotine degradation. Possible intermediates were(More)
BACKGROUND & AIMS T cell immunoglobulin- and mucin-domain-containing molecule-3 (Tim-3) has been shown to influence autoimmune diseases; however, its function in viral infection has not been well-defined. We therefore investigated the expression and regulatory function of Tim-3 in natural killer (NK) cells in chronic Hepatitis B (CHB) infection. METHODS(More)
Society’s drive toward ever faster socio-technical systems, means that there is an urgent need to understand the threat from ‘black swan’ extreme events that might emerge. On 6 May 2010, it took just five minutes for a spontaneous mix of human and machine interactions in the global trading cyberspace to generate an unprecedented system-wide Flash Crash.(More)
BACKGROUND Glycoxidation and lipid peroxidation products accumulate in collagen of various tissues in haemodialysis patients with end-stage renal disease (ESRD). The purpose of this study was to test the hypothesis that increased glycoxidation and lipid peroxidation of aortic elastin is implicated in the cardiovascular complications, particularly(More)
In this experiment, sensitivity to female facial attractiveness was examined by comparing event-related potentials (ERPs) in response to attractive and unattractive female faces within a study-test paradigm. Fourteen heterosexual participants (age range 18-24 years, mean age 21.67 years) were required to judge 84 attractive and 84 unattractive face images(More)
Environmental pollution and food safety are two of the most important issues of our time. Soil and water pollution, in particular, have historically impacted on food safety which represents an important threat to human health. Nowhere has that situation been more complex and challenging than in China, where a combination of pollution and an increasing food(More)
Previous event-related potential (ERP) and brain imaging studies have suggested observer responses to others’ pain are modulated by various bottom-up and top-down factors, including emotional primes. However, the temporal dynamics underlying the impact of emotional primes on responses to others’ pain remains poorly understood. In the present study, we(More)
Society's techno-social systems are becoming ever faster and more computer-orientated. However, far from simply generating faster versions of existing behaviour, we show that this speed-up can generate a new behavioural regime as humans lose the ability to intervene in real time. Analyzing millisecond-scale data for the world's largest and most powerful(More)
A moderately halophilic bacterium (strain NEAU-ST10-39T) was isolated from saline and alkaline soils in the oilfield of Daqing City, Heilongjiang Province, China. The strain was strictly aerobic, Gram-stain-negative, rod-shaped and motile by peritrichous flagella. Its colonies were yellow. It grew at NaCl concentrations of 0.2-15% (w/v) (optimum 4%, w/v),(More)
