The “net neutrality” principle has triggered a heated debate and advocates have proposed policy interventions. In this paper, we provide perspective by framing issues in terms of the positive economic factors at work. We stress the incentives of market participants, and highlight the economic conflicts behind the arguments put forward by the different parties. We also identify several key open ...

BACKGROUND Salt stress is a major factor limiting plant growth and productivity. Salicylic acid (SA) has been shown to ameliorate the adverse effects of environmental stress on plants. To investigate the protective role of SA in ameliorating salt stress on Torreya grandis (T. grandis) trees, a pot experiment was conducted to analyze the biomass, relative water content (RWC), chlorophyll content...

An analytical solution shows that the maximal strain of an impurity-free metallic monatomic chain (MC), or a defect-free nanowire (NW), varies inapparently with mechanical stress but apparently with the separation between the melting point fTmsKdg and the temperature of operation in terms of exphfTmsKd−Tgj, where K is the dimension of the NW (for a MC, K=1.5). Reconciliation of the measured dat...

The hippocampus is sensitive to stress which activates norepinephrine terminals deriving from the locus coeruleus. Melatonin exerts positive effects on the hippocampal neurogenic process and on depressive-like behaviour. Thus, in the present study, an examination was made of the effect of chronic melatonin treatment on norepinephrine content, synthesis, uptake, vesicular transport and degradati...

Background: Osteoporosis is one of the most systemic diseases prevalent among the postmenopausal women attributing to the increased risk of occurrence of fractures. Hence, early detection of this disease is of utmost importance which can be determined by concentration of calcium in saliva and radiographically by quantitative radiomorphometric indices like panoramic mandibular Index (PMI). Objec...

The formation of neutrophil extracellular traps (NETs) is a newly described phenomenon that increases the bacteria-killing ability and the inflammatory response of neutrophils. Because NET generation occurs in an inflammatory microenvironment, we examined its regulation by anti-inflammatory drugs. Treatment of neutrophils with dexamethasone had no effect, but acetylsalicylic acid (ASA) treatmen...
