Humans perceive bitterness via around 25 different bitter receptors. Therefore, the identification of antagonists remains a complex challenge. We previously demonstrated several bitter tasting compounds such as caffeine to induce acid secretion in the stomach and in a human gastric tumor cell line (HGT-1). Here, the results of a fluorescent-based in vitro assay using HGT-1 cells and a human sensory panel testing nine selected potential bitter modulators with or without the bitter compounds caffeine or theobromine, were compared...

The type 1 taste receptor member 3 (T1R3) is a G protein-coupled receptor (GPCR) involved in sweet taste perception. Besides the tongue, the T1R3 receptor is highly expressed in brain areas implicated in cognition, including the hippocampus and cortex. As cognitive decline is often preceded by significant metabolic or endocrinological dysfunctions, regulated by the sweet taste perception system, we hypothesized that a disruption of the sweet taste perception in the brain could have a key role in the development of cognitive dysfunction...

A consumer's decision to purchase beef is strongly linked to its sensory properties and consistent eating quality is one of the most important attributes. Consumer taste panels were held according to the Meat Standards Australia guidelines and consumers scored beef according to its palatability attributes and completed a socio-demographic questionnaire. Consumers were able to distinguish between beef quality on a scale from unsatisfactory to premium with high accuracy. Premium cuts of beef scored significantly higher on all of the scales compared to poorer quality cuts...

OBJECTIVE: Recent studies have suggested that patients with obstructive sleep apnea (OSA) might be affected by olfactory impairment. However, more evidence is needed on the effect that OSA has on the chemical senses (olfaction and gustatory) of these patients, and whether continuous positive airway pressure (CPAP) treatment might help to reverse possible impairment. METHODS: A prospective study was conducted with 44 OSA patients (17 female and 27 male, mean age 54 ± 9...

Enrofloxacin (ENRO) is widely used as an antimicrobial drug for treatment of uncomplicated and complicated infections in veterinary medicine. Its bitter taste limits its clinical applications in veterinary. To mask the bitter taste of this drug, double-coated taste-masking microparticles of ENRO (DTME) were prepared through stearic acid solid dispersion and chitosan-alginate microparticle coating technologies. The taste-masking effect was evaluated by pig feeding experiment. Results showed that DTME exhibited a spherical-like shape (170490μm)...

In the past, dosage regimens authorized for adults were extrapolated to children relying mainly on empirical dosage adjustments. However, children are not small adults, but a distinct and heterogeneous group in terms of physiology, disease occurrence, pharmacokinetics, pharmacodynamics and also psychological, cognitive, and behavioral aspects. Even though it would be helpful to know the physiological changes and the special drug treatment needs in children, this task could not be performed due to ethical reasons...

In recent years, different chlorhexidine formulations have been tested, including an alcohol-free alternative, but the effect of this solution on early biofilm formation is not clear. A crossover, randomized, double-blind clinical trial was conducted to evaluate the effect of two chlorhexidine solutions against supra- and subgingival biofilm formation (NCT#02656251). Thirty-five participants were randomized and asked to rinse twice daily with 15 ml of an alcohol-containing 0.12% chlorhexidine solution, an alcohol-free 0...

Bitter taste elicits an aversive reaction, and is believed to protect against consuming poisons. Bitter molecules are detected by the Tas2r family of G-protein-coupled receptors, with a species-dependent number of subtypes. Chickens demonstrate bitter taste sensitivity despite having only three bitter taste receptors-ggTas2r1, ggTas2r2 and ggTas2r7. This minimalistic bitter taste system in chickens was used to determine relationships between in-vitro (measured in heterologous systems) and in-vivo (behavioral) detection thresholds...

Water-related diseases are a primary problem in Palestine where many residents revert to harvested rainwater as their primary water source due to water shortages within the area. From an environmental engineering perspective, it is already well known that certain situations (e.g., cross contamination) reduce drinking water quality and ultimately cause diseases in a population. In this study, we investigated the social practices and situations that may lead to lower disease occurrence. Towards this goal, we surveyed 382 residents in Yatta to collect data on the water-related diseases that they experienced and the specific situations that might affect the disease occurrences such as the residents' practices (i) for maintaining a high quality of cistern water, (ii) for maintaining the environment around the cistern, and (iii) for managing the wastewater...

BACKGROUND: Obesity leads to olfaction alterations, and this can further impact food choices, appetite, and nutritional status. Bariatric procedures induce weight loss and change in taste and smell perception, but more information is needed, especially using objective olfaction tests. METHODS: A prospective study was conducted during 6 months, with candidates to laparoscopic gastric bypass at a single institution. A preoperative nasofibroscopy and gross smell identification test (The Pocket Smell Test ®) were performed in those meeting the inclusion criteria...

BACKGROUND: Remnant dimension is considered one of the crucial elements determining the success of sleeve gastrectomy (SG), and dilation of the gastric fundus is often believed to be the main cause of failure. OBJECTIVES: The main outcome of this study is to find correlations between remnant morphology in the immediate post-operative stage, its dilation in years, and the long-term results. The second purpose aims to correlate preoperative eating disorders, taste alteration, hunger perception, and early satiety with post-SG results...

In light of the fact that the number of elderly citizens in society is steadily increasing, the search for dietary factors which might prolong mental agility is growing in significance. Coffee, together with its main ingredient, caffeine, has been the focus of much attention from various researchers, as data on its beneficial effects on human health continue to accumulate. Most reports indicate that moderate coffee consumption may in fact lower the risk for common neurodegenerative conditions, i.e. Alzheimer's and Parkinson's diseases...

The patterning of repeated structures is a major theme in developmental biology, and the interrelationship between spacing and size of such structures is an open question. Fungiform papillae are repeated epithelial structures that house taste buds on the anterior tongue. Here, we report that FGF signaling is a critical regulator of fungiform papillae development. We found that mesenchymal FGF10 controls the size of the papillary area, while overall patterning remains unchanged. Our results show that FGF signaling negatively affects the extent of canonical Wnt signaling, which is the main activation pathway during fungiform papillae development, but this effect does not occur at the level of gene transcription...

Olfactory and gustatory dysfunction have been described in different psychiatric disorders. Several studies have found gustatory and olfactory function change in Bipolar Disorders with various results. The aim of this study is to have a systematic review of studies evaluating gustatory and olfactory function in bipolar disorders. After a systematic search, 15 studies on olfaction and 5 studies on taste were included in this review. The UPSIT and Sniffin' Sticks were the most used tests to evaluate smell. Some studies on olfaction described dysfunction in smell identification as potential markers for Bipolar disorders...

Older adults show a preference for positive information, which disappears under high task demands. We examined whether glucose can help older adults preserve their positivity effect (PE) under high cognitive load. One hundred twenty-two adults (40 young and 42 older in Experiment 1; 40 older in Experiment 2) consumed a glucose (25 g) or a taste-matched placebo drink and completed an immediate recall task of emotional word-lists presented under high- and low-load conditions. Older adults showed PEs for low-load lists...

The gustatory system of the sea catfish Plotosus japonicus, like that of other catfishes, is highly developed. To clarify the details of the morphology of the peripheral gustatory system of Plotosus, we used whole-mount immunohistochemistry to investigate the distribution and innervation of the taste buds within multiple organs including the barbels, oropharyngeal cavity, fins (pectoral, dorsal, and caudal), and trunk. Labeled taste buds could be observed in all the organs examined. The density of the taste buds was higher along the leading edges of the barbels and fins; this likely increases the chance of detecting food...
