Although the prevalence of tobacco smoking has been declining in recent years, the use of electronic nicotine delivery systems (ENDS) such as of electronic cigarettes, vaporizers, and hookahs has been steadily rising, especially among adolescents. ENDS are not only advertised to children, but their sale via the Internet has made them easily accessible to youth. In general, children perceive END...

Persistent viral vector-mediated transgene expression in the airways requires delivery to cells with progenitor capacity and avoidance of immune responses. Previously, we observed that GP64-pseudotyped feline immunodeficiency virus (FIV)-mediated gene transfer was more efficient in the nasal airways than the large airways of the murine lung. We hypothesized that in vivo gene transfer was limite...

This paper studies the wasteful effect of bureaucracy on the economy by addressing the link between rent-seeking behavior of government bureaucrats and the public sector wage bill, which is taken to represent the rent component. In particular, public officials are modeled as individuals competing for a larger share of those public funds. The rent-seeking extraction technology in the government ...

Binocular interactions play a prominent role in shaping the axonal arbors of geniculocortical fibers and the arbors of Y cells in the retinogeniculate pathway of the fetal cat. Fiber interactions between the two eyes have also been suggested to regulate the formation of retinal projections to the dorsal lateral geniculate nucleus (dlgn) of the fetal monkey, but whether this reflects structural ...

OBJECTIVES Beryllium sensitisation (BeS) and chronic beryllium disease (CBD) are caused by exposure to beryllium with susceptibility affected by at least one well-studied genetic host factor, a glutamic acid residue at position 69 (E69) of the HLA-DPβ chain (DPβE69). However, the nature of the relationship between exposure and carriage of the DPβE69 genotype has not been well studied. The goal ...

The crystal structures are reported of the isomeric compounds 2-(4-nitro-phen-yl)-3-phenyl-2,3-di-hydro-4H-1,3-benzo-thia-zin-4-one, (I), and 2-(2-nitro-phen-yl)-3-phenyl-2,3-di-hydro-4H-1,3-benzo-thia-zin-4-one, (II), both C20H14N2O3S, being the para-nitro and ortho-nitro forms, respectively, the meta-form of which is known [Yennawar et al. (2013). Acta Cryst. E69, o1679]. The six-membered thi...

1 Stage projection (Lefkovitch) matrices for 21 species of woody plants and 45 herbaceous perennials were extracted from the plant demographic literature or compiled from published data. 2 Each matrix was divided into six regions representing: 1,recruitment ofseeds to the seed pool; 2, recruitment of seedlings or juveniles from current seed production; 3, clonal growth; 4, retrogression, due to...

TOPIC: Occupational and Environmental Lung Diseases TYPE: Medical Student/Resident Case Reports INTRODUCTION: Hypersensitivity Pneumonitis (HP) is an inflammatory and/or fibrotic disease affecting the lung parenchyma. Radiographic or histopathological findings help to categorize HP as either (mixed plus purely fibrotic) non-fibrotic (purely inflammatory), being primary determinant of prognosis....

Governance is a way of exercising power in economic and social resource management of a country. Good governance criteria have different weights and relation with regard to the conditions and information of any country. This study is a descriptive survey and has been carried out to calculate the coefficients and weights of each indicator of good governance in Mena countries and identification o...
