Background: Congenital Hypothyroidism (CH) is one of the reasons for mental retardation and defective growth in neonates. It can be treated if it is diagnosed early. The congenital hypothyroidism can be diagnosed using newborn screening in the first days after birth. Disease mapping helps to identify high-risk areas of the disease. This study aimed to evaluate the pattern of CH using the Poisso...

introduction: one of the major contributing factors, which may cause failure of endodontic treatment, is the presence of residual microorganisms in the root canal system. for years, most dentists have been using calcium hydroxide (ch) as the intracanal medicament between treatment sessions to eliminate remnant microorganisms. reducing the size of ch particles into nanoparticles enhances the pen...

INTRODUCTION This chapter introduces the field of genetic research, in which twin studies are a powerful approach to exploring the genetic basis of complex traits. Twin studies take advantage of the existence of mono-and dizygotic (MZ and DZ) twins and use the comparison of resemblances of MZ and DZ twins as the basis for analysis of variations in human traits and diseases. We describe the basi...

Seed dispersers play a key role in the ecology and evolution of fleshyfruited plants; especially in tropical forests where from 70% to 90% of all woody species are dispersed by vertebrates (Fleming et al., 1987; Jordano, 2000). Local plant communities with a range of fruit types are assembled under a variety of selection pressures and historical effects. Analyses of community-level variation in...

The superconducting CH structure is a novel multicell cavity for the acceleration of protons and ions in the low and intermediate energy regime. The CH structure is a cross-bar-type cavity; it is the first superconducting low energy multicell cavity operated in an H mode. A superconducting CH-prototype cavity with 19 gaps at 0:1 has been built and tested successfully. Maximum surface fields of ...

A seed shadow is the spatial distribution of all seeds dispersed from an individual plant (Janzen, 1970; Nathan and Muller-Landau, 2000; Schupp et al., 2002). The sum of seed shadows across all individuals in a population plus those seeds dispersed from other populations makes up seed rain. For vertebrate-dispersed species, seed shadows are the primary outcome of plant–frugivore interactions, y...

this study was aimed to evaluate the situation of congenital hypothyroidism (ch) in guilan using the screening program and determine the correlation of ch with birth weight, gestational age and seasonality. during 2006 to 2010, in guilan province, neonatal screening for ch by measurement of serum tsh level was performed in 3-5 days after birth. all neonates with tsh level ≥ 5mu/l were referred ...

This article discusses and compares various methods for defining and measuring radical stability, including the familiar radical stabilization energy (RSE), along with some lesser-known alternatives based on corrected carbon-carbon bond energies, and more direct measures of the extent of radical delocalisation. As part of this work, a large set of R-H, R-CH(3), R-Cl and R-R BDEs (R = CH(2)X, CH...
