The purpose of this study was to examine the diagnostic and developmental profiles of 105 children given a PDD-NOS diagnosis. Four subgroups were formed based on the reason for the PDD-NOS diagnosis (fewer than 6 criteria, fewer than 2 social criteria, no repetitive behaviours, and other). Cognitive level, adaptive functioning, autism severity, and the number of DSMIV autism criteria were exami...

With the rapid development of income level and e-commerce in China, low-consumption population is gradually being overlooked by merchants. Nevertheless, founded 2015, Pinduoduo (PDD) has made a spectacular achievement, precisely noticing targeting sinking market, reaching huge success. Thus, this paper, author mainly focused on reason why PDD could thrive competitive Chinese market PDD’s succes...

Background: In this work investigation of the normoxic PAGAT polymer gel dosimeter such as sensitivity, the R2-dose response with post time and the percentage depth dose (PDD) of PAGAT polymer gel dosimeter have been undertaken. Materials and Methods: Using MRI, the formulation to give the maximum change in the transverse relaxation rate R2 was determined to be 4.5% N,N'-methylenbis- ...

BACKGROUND Pervasive developmental disorder (PDD) has an uncertain etiology, no method of treatment, and results in communication deficiencies and other behavioral problems. As the reported recurrence risk is 5%-10% and there are no methods of either prevention or prenatal testing, mothers of PDD children may face unique challenges when contemplating second pregnancies. The purpose of this stud...

Overlooked diseases in agriculture severely impact crop growth, which results significant losses for farmers. Unfortunately, manual field visits plant disease diagnosis (PDD) are costly and time consuming. Although various methods of PDD have been proposed, many challenges yet to be investigated, such as early stage leaf diagnosis, class variations diseases, cluttered backgrounds, computational...

BACKGROUND The relation between dementia with Lewy bodies (DLB) and Parkinson's disease with dementia (PDD) is unknown. OBJECTIVES To compare the cognitive profiles of patients with DLB and PDD, and compare those with the performance of patients with a subcortical dementia (progressive supranuclear palsy) and a cortical dementia (Alzheimer's disease). DESIGN Survey of cognitive features. ...

Emerging evidence suggests that Alzheimer's disease (AD) and Parkinson's disease dementia (PDD) share neurodegenerative mechanisms. We sought to directly compare cerebral perfusion in these two conditions using arterial spin labeling magnetic resonance imaging (ASL-MRI). In total, 17 AD, 20 PDD, and 37 matched healthy controls completed ASL and structural MRI, and comprehensive neuropsychologic...

Abstract. The interest in organic nitrogen and particularly quantifying studying the fate of amino acids (AAs) has been growing atmospheric-science community. However very little is known about biotic abiotic transformation mechanisms clouds. In this work, we measured biotransformation rates 18 with four bacterial strains (Pseudomonas graminis PDD-13b-3, Rhodococcus enclensis PDD-23b-28, Sphing...

Pervasive developmental disorder-not otherwise specified (PDD-NOS) is the most common and least satisfactory of the PDD diagnoses. It is not formally operationalized, which limits its reliability and has hampered attempts to assess its validity. We aimed, first, to improve the reliability and replicability of PDD-NOS by operationalizing its DSM-IV-TR description and, second, to test its validit...
