Results of the National Geographic Smell Survey were used to investigate the effects of pregnancy on olfactory perception and odor-related behavior. The responses to test odors and survey questions of 13,610 pregnant and 277,228 nonpregnant U.S. women between 20 and 40 years of age were analyzed. In comparison to nonpregnant women, pregnant women rated their own sense of smell lower, more often...
BACKGROUND Changes in olfactory functions have been found in many neurodegenerative and psychiatric disorders, including autism spectrum disorders (ASDs). The aim of the present study was to evaluate the relationship between olfactory functions (odor-detection thresholds, odor identification, and odor preference) and autism severity and sensory-related behavior in children and adolescents with ...
Several fundamental questions remain enigmatic concerning human olfactory sensitivity, including (i) whether detection threshold differences exist between the two sides of the nose (and, if so, whether such differences are influenced by handedness) and (ii) whether bilateral (i.e. binasal) stimulation leads to lower thresholds than unilateral stimulation (and, if so, whether the degree of facil...
Introduction We investigated the association between olfactory identification and Alzheimer's disease biomarkers, including amyloid, tau, and neurodegeneration. Methods Thirty-four older adults, including 19 cognitively normal (CN), 10 subjective cognitive decline (SCD), and 5 mild cognitive impairment, underwent amyloid positron emission tomography, magnetic resonance imaging, and the Univer...
Loss of the sense of smell is among the first signs of natural aging and neurodegenerative diseases such as Alzheimer's and Parkinson's. Cellular and molecular mechanisms promoting this smell loss are not understood. Here, we show that Drosophila melanogaster also loses olfaction before vision with age. Within the olfactory circuit, cholinergic projection neurons show a reduced odor response ac...
Code smells are more likely to stay inter-connected in software rather than remaining as a single instance. These code smell clusters create maintainability issues in evolving software. This paper aims to understand the evolution of the code smells in software, by analyzing the behavior of these clusters such as size, number and connectivity. For this, the clusters are first identified and then...
OBJECTIVE Kallmann syndrome (KS) is a genetic disorder with the distinctive features of hyposmia or anosmia and hypogonadotropic hypogonadism. Though hyposmia/anosmia can be evaluated by both objective and subjective smell tests, there is no study comparing these two methods in KS. The aim of the present case series was to discuss the results of objective and subjective smell tests and compare ...
