The disease is characterized by the abrupt onset of a febrile illness usually 2-7 d (range 2-14) after exposure to the virus and by subsequent severe changes in mental status, hemorrhagic manifestations, and hepatorenal failure ( 1 , 4 ). (cdc.gov)
a severe and sometimes fatal Type 1 reaction in a susceptible person after a second exposure to a specific antigen (e.g., food, pollen, proteins in latex gloves, or penicillin) after previous sensitization. (cdc.gov)
Severe exposures may require several days of observation before the patient is clear of anticholinergic effects. (medscape.com)

Japan's labor department issued a notice in February requiring measures to protect workers from exposure to nanomaterials: It may be the world's first nano-specific regulation affecting actual practices. (yale.edu)

Ailshire's research, published earlier this year in the Journal of Alzheimer's Disease , showed a strong association between cognitive deficits and air pollution among people with lower levels of education in 2004. (agedcarenews.com.au)
Finch's research on mice, published earlier this year in the Journal of Alzheimer's Disease , also found evidence of lower neurotoxicity of air pollution over time. (agedcarenews.com.au)
Research from Jennifer Ailshire, published in the Journal of Alzheimer's Disease , also found evidence of lower neurotoxicity of air pollution over time. (freshairmatters.com)

Much of the existing literature investigating the effects of air pollution in the CNS has predominately been reported in males, with little known regarding the effects in females. (nih.gov)
This paper reviews studies that assess the effects of air pollution on brain development in mice and in children. (growkudos.com)

In a meta-analysis of 86 studies spanning 39 countries, researchers found that childhood eczema is strongly linked to smoking exposure (including second-hand smoke), but not when the mother smokes during pregnancy. (learnskin.com)
Researchers at the New Delhi based Centre for Science and Environment have found alarmingly high levels of pesticides in blood samples of villagers in Punjab, the showpiece state of India's green revolution. (indiatogether.org)

Historically, many studies have highlighted the nexus between air pollution and its detrimental effects on the brain. (earth.com)

Also worth noting is the fact that while the antioxidant's ability to reduce blood pressure is good news for those with high blood pressure, people who suffer from low blood pressure may have problems with this one. (photonuriacastilla.com)

Air pollution: Could dirty air cross the brain-blood barrier? (medicalnewstoday.com)
This occurs either by penetrating the brain directly through the nose or crossing the blood-brain barrier. (earth.com)
Once inhaled, they pass directly from the nose up and into the brain, beyond the blood-brain barrier that normally protects the brain from dust or other invaders. (agedcarenews.com.au)
Preclinical and clinical activity of DZD1516, a full blood-brain barrier-penetrant, highly selective HER2 inhibitor. (medscape.com)
The level of Aβ in the brain is a balance between synthesis, degradation, and fluxes across the blood-brain barrier (BBB). (thestemcellfoundation.com)
Brain-to-blood transport was similar for Al-Aβ42 and Aβ42. (thestemcellfoundation.com)
Their exposure was in the womb, where no blood brain barrier protected their developing brains. (raisingnaturalkids.com)
Moreover, experiments in animals suggest that traffic-related air pollution is a developmental neurotoxicant-a factor that disrupts brain development. (plos.org)
Studies on animals have shown that even a single, low-level exposure to certain organophosphates, during particular times of early brain development, can cause permanent changes in brain chemistry. (indiatogether.org)
Neurovascular coupling is a precise mechanism that induces increased blood flow to activated brain regions, thereby providing oxygen and glucose. (biomedcentral.com)

This does not include lighters, air fresheners, and other smoking-related products or accessories. (msdmanuals.com)

On September 8, 2009, a 22-year-old male US soldier who worked in field operations outside Kandahar City, Afghanistan, sought care at a military medical clinic for a 4-d history of nonbloody diarrhea, abdominal pain, bloody emesis, and fever (39.2°C). The patient reported frequent outdoor activities, tick bites, and exposure to undercooked goat meat and blood the week before the onset of illness. (cdc.gov)

It is the process by which atmospheric constituents are transferred by air motions to the natural surfaces like vegetation ( Wesely and Hicks, 2000 ), which is significant especially, in the regions where dry weather conditions prevail. (aaqr.org)
In contrast, most patients with burns caused either by contact with hot surfaces or sun exposure are managed as outpatients. (medscape.com)

Children attending schools with higher traffic-related air pollution had a smaller improvement in cognitive development. (plos.org)

10 Shocking Facts about Indoor Air Quality (IAQ) The worst air quality you experience every day just might be in your living room. (generalfilters.com)
In some cases, indoor air pollution was 100x greater. (generalfilters.com)

A statistically significant decline in UE occurred during the exposures. (cdc.gov)
This further suggested that the improvements with cognitive decline were linked to a drop in exposure to high pollution among older adults. (agedcarenews.com.au)
Within 30 minutes from the last cigarette, blood pressure and pulse decline and return to normal. (msdmanuals.com)

The points in the figures showing no-observed-adverse-effect levels (NOAELs) or lowest- observed-adverse-effect levels (LOAELs) reflect the actual doses (levels of exposure) used in the studies. (cdc.gov)
