“…The reliability of threshold determination, while acceptable, is lower than for other olfactory measures [22]. In addition, odours need to be replaced regularly, as they become weaker or, as in the case of n-butanol, oxidise or otherwise change their character over time [23]. According to Pause et al [24], it is important to test different odours to obtain valid data on olfactory thresholds.…”

Background: Olfaction and its relation to mental health is an area of growing interest. Brain areas linked to olfaction partially overlap with brain areas involved in psychiatric disorders; consequently, the study of olfactory function allows us to explore the integrity of these brain areas with a non-invasive and effective method. Accordingly, the aim of this paper is to review olfactory function in affective and anxiety disorders. Methods: For this purpose, an extensive literature review of English-language studies on olfactory function in patients with the aforementioned pathologies was performed using several online databases. A manual search of relevant journals and books as well as reference lists from selected papers was also performed. Results: The available data show that depressed patients are usually characterised by preserved olfactory function, except for detection threshold, where contrasting reports have been found. Bipolar disorder has been studied to a lesser extent, but the findings have shown a lack of impairment in most cases. Research on seasonal affective disorders is scant, and future studies are needed to make conclusions. Anxiety disorders have been scarcely approached, but the results note identification deficits in obsessive-compulsive and posttraumatic stress disorders. Conclusions: Olfactory assessment appears to be a complementary, valuable research tool in the study of psychiatric disorders. However, further investigation is needed to improve our understanding of olfactory function in these disorders.

“…47 Another limitation of such tests is that the odors need to be replaced regularly, as they become weaker or, as in the case of n-butanol, oxidize or otherwise change their character over time. 58 It is important to emphasize that threshold values are dependent on the psychophysical procedure used, as well as the diluent and method of delivery, making comparisons across a number of studies problematic.…”

Given the availability of practical clinical olfactory tests, the modern rhinologist can easily quantify cranial nerve (CN) I function. The application of such tests has led to a new understanding of the effects of nasal disease on olfactory function. Except in cases of total or near-total nasal obstruction, olfactory and airway patency measures usually are unrelated, in accord with the concept that rhinosinusitis primarily influences olfactory function by apoptotic pathological changes within the olfactory neuroepithelium.

“…In this context, polymer blending is of great interest since it is an attractive and cost effective way for making materials with modulated properties for vapor permeation [9][10][11][12]. Conversely, the vapor permeation technique is a good tool for the thermodynamic characterization of polymer blends [13][14][15]. The analysis of the equilibrium sorption of a vapor by a blend can provide valuable information on polymer-polymer interactions and the related morphology.…”

Natural rubber (NR)/Acrylonitrile butadiene rubber (NBR) blend membranes, prepared by using dicumyl peroxide as the crosslinking agent, were tested for their vapor permeation characteristics. The permeation studies were conducted using three chlorinated hydrocarbons, viz. dichloro methane, chloroform, and carbon tetrachloride. The effects of the blend ratio, compatibilizer, penetrant size, and temperature on the vapor permeability of the membranes were investigated. The permeability of the blends was found to decrease with an increase in the NBR content, which has been attributed to the inherent solvent resistant nature of NBR. The permeation behavior of compatibilized blends was compared with those of the uncompatibilized blends. The separation efficiencies of the membranes were also tested using chloroform/acetone mixtures to complement the observations from the vapor permeation experiments.
