*  SICB - 2012 meeting - Abstract Details
It is widely assumed that dogs (Family Canidae) have an exceptional sense of smell, however there is little comparative evidence to support this claim. We used 3D visualization of CT scans to measure the bony surface areas of olfactory (OSA), respiratory (RSA) and, combining these, total (TSA) turbinates in skulls of 10 species of canids as well as 12 previously studied, terrestrial species of the Superfamily Arctoidea (Ursidae, Mustelidae, Mephitidae, Procyonidae). We examined scaling relationships and asked if ecological variables such as diet and home range size correlate with olfactory ability, as shown by ratios of OSA and RSA. After phylogenetic correction, we found that canids show greater positive allometry in TSA relative to arctoids, as a result of positive allometry in OSA and isometry in RSA. Canids also have a greater proportion of their turbinate area devoted to olfaction than respiration, suggesting that canids have enhanced olfactory ability relative to most arctoids. ...

*  Specific Mesenchymal/Epithelial Induction of Olfactory Receptor, Vomeronasal, and Gonadotropin-Releasing Hormone (GnRH) Neurons
We asked whether specific mesenchymal/epithelial (M/E) induction generates olfactory receptor neurons (ORNs), vomeronasal neurons (VRNs), and gonadotropin-releasing hormone (GnRH) neurons, the major neuron classes associated with the olfactory epithelium (OE). To assess specificity of M/E-mediated neurogenesis, we compared the influence of frontonasal mesenchyme on frontonasal epithelium, which becomes the OE, with that of the forelimb bud. Despite differences in position, morphogenetic and cytogenic capacity, both mesenchymal tissues support neurogenesis, expression of several signaling molecules and neurogenic transcription factors in the frontonasal epithelium. Only frontonasal mesenchyme, however, supports OE-specific patterning and activity of a subset of signals and factors associated with OE differentiation. Moreover, only appropriate pairing of frontonasal epithelial and mesenchymal partners yields ORNs, VRNs, and GnRH neurons. Accordingly, the position and molecular identity of ...

*  Semaphorin 3A-mediated axon guidance regulates convergence and targeting of P2 odorant receptor axons - Schwarting - 2004 -...
Semaphorins are known to play an important role in axon guidance of vertebrate olfactory sensory neurons to their targets in specific glomeruli of the olfactory bulb (OB). However, it is not clear how semaphorin-mediated guidance contributes to a systematic hierarchy of cues that govern the organization of this system. Because of the putative role that odorant receptor molecules such as P2 could play in establishing appropriate glomerular destinations for growing olfactory axons, we have also determined the spatial organization of P2 glomeruli in semaphorin 3A (Sema3A) mutant mice. First, in the postnatal OB of control and Sema3A−/− mice, we analysed the trajectories of olfactory axons that express the Sema3A receptor, neuropilin-1 (npn-1) and the positions of npn-1+ glomeruli. Sema3A at the ventral OB midline guides npn-1+ axons to targets in the lateral and medial OB. Absence of Sema3A permits many npn-1 axons to terminate aberrantly in the rostral and ventral OB. Second, in Sema3A−/− ...

*  Solid perfume - Wikipedia
Solid perfumes or cream perfumes are perfumes in solid state rather than the liquid mix of alcohol (ethanol) and water used in eau de parfum, eau de toilette, eau de cologne, etc. Normally the substance that gives the cream its base comes from a type of wax that is initially melted. Once melted, a scent or several scents may be added. Solid perfume is used either by rubbing a finger or dipping a cotton swab against it and then onto the skin. Sometimes solid perfume can take more time for the deeper notes to come out than a spray perfume. The latest solid perfumes are designed as handbag aromas, so a compact way of making perfume more portable. Historically, ointment-like unguents have been used as a type of solid perfume since Egyptian times.

*  Efficacy of (WaterWorks®)Douching Device for Elimination of Perceived Vaginal Odor Not Caused by BV or Vaginitis - Full Text...
Vaginal symptoms, including abnormal odor with or without complaints of discharge, are relatively common complaints. It is generally assumed that most women with these complaints have a vaginal infection, bacterial vaginosis, trichomoniasis, or vulvovaginal candidiasis. However, investigators suggest that there is a large population of women who complain of odor with or without complaints of discharge, and in whom no clear cause can be found. For these women, there are currently no treatment options.. Anecdotal evidence suggests that stainless steel used with just water has an effect in reducing odors and is so used to reduce odors on hands by chefs. The Water Works® Douching Device is a light-weight (1oz) stainless steel douching device that was developed to aid in the treatment of vaginal odor. Additional anecdotal evidence suggests that douching with the Water Works® Douching Device had little or no affect on the vaginal Eco-System (e.g. good bacteria, Lactobacilli)..

*  What Are Essential Oils? | Eterna Health Food
We all know about the everyday power of scent: how a particular perfume reminds you of your mother, or when the smell of your favorite restaurant brings you back to your first date there. But did you know that some scents can actually improve your health? Essential oils can also help you relax or sleep, or improve your skin or digestion - their benefits go well beyond a pleasant smells. Essential oils can have a healing effect mentally, physically, and emotionally. You can apply them directly onto your skin, inhaling, or use through a diffuser.. Technically, essential oils aren't oils at all, as they lack fatty acids. Rather, they're highly concentrated plant components. It can take a huge amount of a plant to get out even a small portion of essential oil. For example, 4,000 pounds of Bulgarian roses are needed to get just one pound of oil. This is why some essential oils are particularly expensive.. Essential oils are one of the greatest untapped resources of the world. The ...

*  Brain Sciences | Free Full-Text | Dysfunctional Incidental Olfaction in Mild Cognitive Impairment (MCI): An...
Our study provides evidence that Mild Cognitive Impairment (MCI) is associated with olfactory dysfunction on both conscious and non-conscious levels. MCI patients and age-matched controls underwent a face processing task during which sympathy decisions had to be made via button presses. Incidentally, some of the faces were associated with a simultaneously presented odour. Although attention was paid to faces, brain activities were analysed with respect to odour versus no-odour conditions. Behavioural differences were found related to overall face recognition performance, but these were not statistically significant. However, odour-related neurophysiology differed between both groups. Normal controls demonstrated brain activity differences between odour and no-odour conditions that resemble difference activity patterns in healthy young participants as described in a previous magnetoencephalography (MEG) study [1]. They showed odour-related activity patterns between about 160 ms and 320 ms after stimulus

Genetic analysis of host attraction and repulsion in Aedes aegypti. Matthew DeGennaro, Ph.D.. Host odor is a long-range, attractive cue that guides mosquitoes to their hosts. The mosquito perceives differences in host odor, both between and within species, to determine which host to feed upon. Until recently, the molecular mechanism by which mosquitoes translate host odor information into host-seeking behavior has only been inferred. To shed new light on mosquito olfaction and host-seeking behavior, we developed a technique for targeted mutagenesis in Aedes aegypti using zinc-finger nucleases. Using this technique, my co-authors and I demonstrated that orco, an olfactory co-receptor, enables host odor attraction, the preference of mosquitoes for human hosts, and DEET-driven repellency. In addition, the establishment of loss-of-function genetics in Aedes aegypti using zinc-finger nucleases has opened new paths of investigation in vector biology.. How volatile DEET drives repellency in insects is ...

By RICK WEISS The process of writing legislation has often been compared to sausage-making, but rarely is rotten meat actually present at a congressional hearing. Yet some is expected this afternoon at a House Agriculture Committee hearing 'to review technologies in the meat industry.' The hearing is in the cross hairs of activists opposed to the spiking of packaged red meats with carbon monoxide gas, which keeps cuts crimson no matter how old the meat. Unable to wrangle a place on the witness list, some plan to make their olfactory point in the hallway.

*  Cloves - Flavorful Fortified Food
The cloves oil is called eugenol, and studies have shown that it prevents toxicity from some pollutants, cancer of the digestive tract and inflammation. It's also been widely used in this country for tooth aches because of its analgesic properties. As a child, our family's doctor used to apply a Vaseline and cloves ointment to my chest and back, cover them with a warm damp towel then a dry towel and plastic wrap for my asthma. I loved the smell and the clearing of my lungs, and loved him for coming to me every time I was sick. So my memories of cloves (called clavos in Spanish) run deep and way back. But being a food lover, my best memories are of cloves as a spice, such a delicious aroma, such an exciting taste. If you were ever a Girls Scout, I'm sure you stuck cloves into oranges every year before Christmas and made Pomander balls. I did! I didn't want to wash my hands afterwards because I loved the smell on my fingers of the citrus and cloves. Years later as a Brownie ...

*  Cottage Q&A: How to deal with sulphur-scented tap water - Cottage Life
This article was originally published in the Early Summer 2016 issue of Cottage Life magazine.. Our water source is a well, and the water has a very strong rotten-egg sulphur smell. Can we fix this problem without installing expensive filters? We'd like to avoid that.. -Stinking Mad. We hear you. Whole-house water-filtration systems can cost more than $1,000 (and that's on the low end). You'd probably rather spend that hard-earned cash on basically anything else.. "The most likely cause of a sulphur smell in water wells is from sulphate-reducing bacteria," says Patrick Boyle of the Water Security Agency in Moose Jaw, Sask. "These bacteria chemically change natural sulphates in water to hydrogen sulphide, and they tend to flourish in water-distribution systems." Since the levels of bacteria found in a well are typically low, drinking the water isn't unsafe. It's just gross.. You can disinfect your well with shock chlorination. This involves putting household bleach in the ...

*  How to Use Ashwagandha for Cognitive Function and Improved Memory | The Hearty Soul
This article is shared with permission from our friends at Dr. Mercola.. Ashwagandha (Withania somnifera) is an herb that's been an important part of Ayurvedic medicine since ancient times. Literally translated from its Sanskrit roots, ashwagandha means "smells like a horse," which may hint more at its essence than its actual smell. It's suggested by some Ayurvedic health practitioners that the herb was so named because it provides the strength and stamina of a horse. Meanwhile, its species name, somnifera, is a nod to its sedative properties.1. While ashwagandha is sometimes referred to as Ayurvedic or Indian ginseng,2 it is not in the ginseng family. The ashwagandha plant is a shrub with yellow-green flowers and orange-red berries native to Pakistan, India and Sri Lanka.. The leaves and root are most often used medicinally. According to Ayurvedic tradition, ashwagandha is considered a rasayana herb, which means it may promote youth and longevity while alleviating ...

*  Passing the Smell Test
Modern skunks have a modest diversity in the New World, comprising the striped and hooded skunks (genus Mephitis, two species), spotted skunks (genus Spilogale, four species), and hog-nosed skunks (genus Conepatus, four species). Less familiar (at least to Westerners) are the Southeast Asian stink badgers (genus Mydaus, two species), which, as implied in their common name, have long been thought of as badgers but are actually skunks.. [media:node/2214 caption medium vertical left]. One of the key morphologic characters of the skunk family is an enormously enlarged chamber in the middle ear region. In mammals the middle ear is enclosed by a rounded bony enclosure called the tympanic bulla, with the eardrum at its entrance. Air-borne sounds received by the eardrum are transmit-ted through three tiny bones (called auditory ossicles) into the inner ear, where the vibra-tions are sensed by nerves and converted into electrical im-pulses that are sent to the brain. The middle ear space is filled with ...

*  effect of far infrared lamp in a domestic refrigerator
I have been very curious to know more of effects of the far infrared lamp, since my wife brought a new refrigerator ( goldstar). The refrigerator has a far infrared lamp in the top of the food compartment, the aim of this lamp is to preserve meat with out freezing, we left some fresh beef for two weeks and it did not have any change in smell and color. We eat it without any complaint the next day. I have performed some of the next home experiments: I introduced a thermometer inside the fridge to check a difference of one degree (centigrade) on temperature on the surface of the meat when the infrared lamp is on and off. I wrapped three pieces of meat, one with aluminum, one with transparent plastic film and another in side a glass bottle, the only one that survived was the piece inside the plastic film. It seems to me that there is a green house effect??? The refrigerator manual says that infrared rays keeps the taste and the smell of the food for long by increasing the ...

In the upcoming June Annals of the American Thoracic Society, Donald P. Tashkin, MD, emeritus professor of medicine and medical director of the Pulmonary Function Laboratory at the David Geffen School of Medicine at University of California, Los Angeles, reviewed the research on the effects of marijuana smoking on the lungs. Dr. Tashkin finds that in studies of regular smoking of marijuana by itself, there is "no clear link between marijuana use and the development of COPD [chronic obstructive pulmonary disease] or lower respiratory tract infections.". Additionally, "findings from a limited number of well-designed epidemiological studies do not suggest an increased risk for the development of either lung or upper airway cancer from light or moderate use, although evidence is mixed concerning possible carcinogenic risks of heavy, long-term use," Dr. Tashkin notes. "In summary, the accumulated weight of evidence implies far lower risks for pulmonary complications of even regular heavy use of ...

*  An Atypical Etiology of Anosmia | MedCrave
The term anosmia is used to describe the complete absence of useful smelling ability [1]. Olfactory disorders have four major causes: upper respiratory infections, sinonasal diseases, head trauma and neurodegenerative illnesses (Parkinson's disease, Alzheimer's disease, etc.). Upper respiratory infections (URI), especially viral, and sinonasal diseases (allergic rhinitis, chronic rhinosinusitis with or without nasal polyps, sinonasal benign or malignant tumors) together are responsible for 32 to 72% of olfactory disorders, depending on the chosen studies. Sinonasal diseases alone are responsible for 14% of olfactory disorders [2,3].. Smell loss due to URI has at the moment no available therapy and, on the other hand, some sinonasal disorders often respond considerably to proper treatment. In spite of the importance of this distinction, this is not always easy, due to the nonspecific findings presented by some patients. As a result, the etiology is often incorrectly thought ...

This particular perfume is a beautiful yet haunting mixture of chamomile, lavender, jasmine and orange flower - a gentle yet poignant offering that represents the smells and memories that Mark has of his father's garden. I would describe this as a floral fragrance - yet it's not a typical, 'run of the mill' example. It's clear from the get-go that chamomile is the dominating note here - a fresh, uplifting but slightly apply aroma that jumps out at you from inside the bottle. Both the jasmine and orange flower come through as well, complimenting the aroma of the chamomile and adding the natural sweetness of fresh flowers. The lavender is almost an afterthought - the final layer that brings it all together and adds a silky, sultry finishing note. It's more of a herbaceous floral aroma than a straight up flowery combination but this doesn't make it any less beautiful. ...
