heredity hearing loss (hl) is the most prevalent sensory disorder and most cases are non-syndromic. eighty percent of non-syndromic sensorineural deaf patients show an autosomal recessive pattern of inheritance. to date, 47 genes and 98 loci have been reported for this mode of inheritance. previous studies in our center showed the high prevalence of dfnb3 among iranian deaf families. pjvk (dfnb...

According to the research on time perspective, the present time perspective is positively correlated with risky behaviors. Thus, when educating students, teachers tend to encourage them to have the future time perspective instead of the present time perspective. The risky behavior is also related to addiction problem. Recently, technology addiction such as smart phone addiction is one of the an...

Two strains of Saccharomyces cerevisiae were constructed that are conditional for synthesis of the 60S ribosomal subunit protein, L16, or the 40S ribosomal subunit protein, rp59. These strains were used to determine the effects of depriving cells of either of these ribosomal proteins on ribosome assembly and on the synthesis and stability of other ribosomal proteins and ribosomal RNAs. Terminat...

Before 2004, nearly all GRB afterglow data could be understood in the context of the external shocks model. This situation has changed in the past two years, when it became clear that some afterglow components should be attributed to the activity of the central engine; i.e., the central engine afterglow. We review here the afterglow emission that is directly related to the GRB central engine. S...

The quinuclidinium cation of the title compound, C(7)H(14)NO(+)·Cl(-), shows a twist along the C-N pseudo-threefold axis, with N-C-C-C torsion angles of -16.0 (1), -16.9 (1) and -15.6 (1)°. The crystal structure is stabilized by N-H⋯Cl and O-H⋯Cl hydrogen bonds, forming infinite chains along the a and b axes.

mortality rate indicator for children under 5 years old is one of the important indicators in countries' development. identifying the most common causes of mortality is one of the most important attempts to reduce mortality in children less than 5 years. the purpose of this study was to identify distribution of the mortality causes in iranian children less than 5 years.this cross-sectional stud...
