A variety of scaling laws are known for the mammalian neocortex relating gray matter volume, total number of synapses [1, 2], white matter volume [3–9], number of neurons [6, 10–12], surface area [4, 5, 13–16], axon caliber [1, 17], and number of cortical areas or compartments [18]. These neocortical scaling laws appear to be a consequence of selection pressure for a sheet-like structure (namel...

The objective of the present study was to determine the reliability and validity of the Persian translation of the Pediatric Quality of Life Inventory (PedsQLTM) 4.0 Generic Core Scales Young Adult Version in an Iranian sample of young adult patients with rheumatoid arthritis (RA).

Dust storm is one of the criteria for air pollution, and pollution by Heavy Metal(HM) is one of the major environmental problems in the world. The objective of the present study was to assess some of HMs concentrations in the leaves and bark of cypress and atmospheric falling dust along the Yazd highway, Yazd Province, Iran. The total concentrations of cadmium (Cd), cobalt (Co), copper (Cu), ni...

Since changes in trade openness are typically confounded with other factors, it has been difficult to identify the labor market consequences of increased international trade. The advent of the United States Interstate Highway System provides a unique policy experiment, which I use to identify the effect of reducing trade barriers on the relative demand for skilled labor. The Interstate Highway ...

Studies on acute effects of particulate matter (PM) air pollution show significant variability in exposure-effect relations among cities. Recent studies have shown an influence of ventilation on personal/indoor-outdoor relations and stronger associations of adverse effects with combustion-related particles. We evaluated whether differences in prevalence of air conditioning (AC) and/or the contr...

Genetic factors have an important role in the incidence of osteopenia in thalassemia patients. The purpose of this study was to investigate the effect of the Pro12Ala polymorphism of the peroxisome proliferator-activated receptor-γ (PPARγ) gene on bone mineral density (BMD) and subsequently, the rate of osteopenia in β-thalassemia major (β-TM) patients. Blood samples were obtained from 156 β-TM...
