Eisenia hortensis Detects Chemesthetic Irritants through TRP Channels
… chemesthesis i.e., the detection of chemical irritants. Based on a ecotoxicology soil sampling method which expels earthworms with allyl isothiocyanate, a common Transient Receptor Potential 1 (TRPA1) channel agonist, we hypothesized that earthworms possess TRPA1-like channels. We examined …

THE RESPIRATORY RESPONSE OF TRPV1 KNOCKOUT MICE TO TRIGEMINAL IRRITANTS
… are stimulated by a wide variety of chemical irritants. However, the mechanism of stimulation is known for only a few compounds. TRPV1 channels, for example, are activated by capsaicin. The present study was designed to address this question. Classic experiments have established that exposure …

Developing an integrated preventive framework for construction workers exposed to silica dust and chemical irritants in Zambia.
… bring hazards such as silica dust and chemical irritants to site personnel. Silica dust and chemical irritants are produced from activities such as demolition, drilling, concrete mixing, brick and concrete block cutting, sawing, tile cutting, painting and grading. Silica dust can cause …

From Irritants to Satisfaction: A Model of a Theory of Meaning Applied to Reading the‘Sabbath of the LORD’ Motif In Exodus 16
The shift in biblical studies since the Age of Enlightenment from the so-called positivist (i.e. modernist) paradigm to the postpositivist (i.e. postmodern) paradigm has become a matter of (de)centralisation of meaning and interpretation. To contribute to the topic, I argue that there is a need for …

Evaluation of the Functional Roles of TRPA1 Homologs, Painless and dTRPA1, in Chemical Nociception in Drosophila
The detection of harmful chemical irritants is important for the avoidance of potential tissue-damaging and life threatening compounds. There are multiple physiological systems that exist to detect these irritants, and one specific target of these compounds is the TRPA1 channel. Drosophila possess …

Acute Pulmonary Response in Landscape Workers: Job Redesign
… response is associated with respiratory irritants that are found in materials such as soil, grain, and compost, especially when these materials have become moist. Some of the culprits that have been identified as causative agents of respiratory spasms are endotoxin, fungal spores, and …

Community acquired bacteraemia in the elderly
… by exposure to ultraviolet light and toxic irritants to the immune system which becomes progressively less responsive to antigenic stimuli. Bacteraemia follows a focal infection and thus any change which results in increased infection will result in an increased chance of bacteraemia. …

Periodontal aspects of Endodontics
… on this topic. Pathogenic bacteria and other irritants may migrate from the pulp to the periodontium and vice versa through physiological communication pathways such as apical foramen, dentinal tubules and lateral canals. Such exchange of pathogens often contributes into the development of the …

Childhood Asthma Deaths in North Carolina: 1999-2012

Making waste public
… I read these ruptures or excesses as productive irritants for working and reworking how we conceptualize public space. It is within the friction of overlapping claims made to an issue such as waste that public life emerges.

Identifying Potential Agonists Of TRPA1 Using A Heterologous Expression System And Transgenic Mice
Chemical irritants stimulate the trigeminal nerve through many different receptor proteins, including TRP channels. TRPA1, a highly conserved TRP channel, is known to be activated by over ninety compounds. As TRPA1 is promiscuous in nature, it was considered a likely receptor for stimuli activating …

Toileting dysfunction in children with sensory under-responsiveness: the sensory modulation bowel and bladder questionnaire (SM-BBQ)
… intake, removing or managing bowel and bladder irritants, diet changes, timed or scheduled voids, toilet postures and avoidance of holding maneuvers, manual therapy, and biofeedback. These forms of treatment have shown a roughly 50% success rate six months to several years after treatment is …

Comparison of Airway Response in Recurrent Airway Obstruction-Affected Horses Fed Steamed Versus Non-steamed Hay
… airway inflammation in response to inhalation of irritants including hay molds. Steaming hay reduces fungal content, but the effect on the antigenic potential has not been investigated. We tested the hypothesis that RAO-affected horses develop less severe clinical disease when fed steamed versus …

Thriving on sustainable development: sustainable autopoietic organisations
… direct or indirect involvement of NGOs and other irritants. Thirdly, Sustainable Development can be highly attributed to law but when the environment of law is not satisfied, rules of behaviour outside the legal framework are created by organisations such as NGOs. The research shows that …

Jennings's two terms as governor were his most valuable years of public service. His persistent support of state-financed public education, as well as aid …

The effect of compression ratio on emissions from an alcohol-fueled engine
… volatile aldehydes are eye and respiratory tract irritants; therefore, it is only a matter of time before they too are strictly regulated. This thesis focuses on a systematic analysis of aldehyde emissions from alcohol fuels with respect to compression ratio. Compression ratio has been selected as …

Deciphering the mechanism of foxa2 inactivation by respiratory pathogens in chronically diseased lungs

In vitro cytotoxicity and skin irritation testing of antimicrobial conjugated electrolytes : interactions with mammalian cells
