چکیده
It is now possible to identify hearing loss in early infancy. Consequently, early hearing detection and intervention programs are being implemented worldwide. It is a generally accepted goal of such programs to enroll infants in comprehensive and effective family-centered intervention programs by 6 months of age. A second recent development in the hearing health care field relates to the availability of a new generation of fully digital hearing instruments. These new hearing aids embody a remarkable array of capabilities and options. However, a real challenge to professionals working with these early-diagnosed infants is to know how to achieve the best match between the unique auditory characteristics of each infant and the advanced and relatively complex capabilities that are now available in modern digital hearing instruments. Without the application of scientifically based approaches to fitting, it is possible for a hearing aid fitting to be well off the mark. An unfortunate consequence of an inaccurate fitting is to lose the developmental advantages in auditory learning that result from early identification. Our clinical research program in pediatric hearing aid fitting has evolved from the innova-

Revisiting the evidence linking Arctic amplification to extreme weather in midlatitudes
[1] Previous studies have suggested that Arctic amplification has caused planetary-scale waves to elongate meridionally and slow down, resulting in more frequent blocking patterns and extreme weather. Here trends in the meridional extent of atmospheric waves over North America and the North Atlantic are investigated in three reanalyses, and it is demonstrated that previously reported positive t...
متن کاملCyclic amplification of protein misfolding: application to prion-related disorders and beyond.
Diverse human disorders, including the majority of neurodegenerative diseases, are thought to arise from the misfolding and aggregation of protein. We have recently described a novel technology to amplify cyclically misfolded proteins in vitro. This procedure, named protein misfolding cyclic amplification (PMCA), is conceptually analogous to DNA amplification by PCR and has tremendous implicati...
متن کاملThe relation between the number of sunspots and fluctuation in the trend of climatic components in Iran during recent decades
This analysis was conducted on 31 synoptic stations in Iran. Initially, the Mann-Kendall test was administered in order to analyse the trend of alterations of these two components over time and the results suggest that 16% of the stations show significant relationship with annual precipitation (positive and negative). More stations showed significant relationships between sunspots and minimum a...
متن کاملMolecular detection and genotyping of pathogens: more accurate and rapid answers.
Rapid molecular methods have enhanced the capabilities of laboratories to identify and characterize microbial pathogens in greater detail. Nucleic acid amplification strategies and advances in amplicon detection have been key aspects in the progress of molecular microbiology. Sophisticated new amplification-detection combinations are resulting in many applications in laboratory testing for infe...
متن کاملElectrochemical real-time nucleic acid amplification: towards point-of-care quantification of pathogens.
Real-time nucleic acid amplification, whereby the amplification rate is used to quantify the initial copy number of target DNA or RNA, has proven highly effective for monitoring pathogen loads. Unfortunately, however, current optical methods are limited to centralized laboratories due to complexity, bulk and cost. In response, recent efforts aim to develop lower-cost, electrochemical real-time ...
متن کاملArctic tropospheric warming amplification?
Relative rates of temperature change between the troposphere and surface, and the mechanisms that produce these changes, have long been a contentious issue. Graversen et al., predicated upon the ERA-40 reanalysis, report polar tropospheric amplification of surface warming and attempt to explain this finding dynamically. Here we show (1) that data from satellites and weather balloons indicate th...
