and 40% score serious to profound retardation) [ 20] and epilepsy (40% of cases) [ 21]. Co-morbid behavioural and psychiatric conditions associated with the core symptoms include aggression, disruption, hyperactivity, self-injury, sensory abnormalities, anxiety, depression and sleeping disturbances. r gasquet The most frequent non-neurological co-morbidities associated with ASD are gastrointestinal abnormalities and underlying inflammation [ 22, 23, 24, 25, 26, 27, 28], feeding difficulties and food sensitivities [ 29]. Autistic symptoms normally appear before 36 months of age, and regression or loss of skills occurs in 30% of affected children, usually between 18 and 24

chromosome 15 have been particularly associated [ 56]. Deletions on chromosome 16p11 have also shown to be associated with ASD, mental retardation and other developmental disabilities [ 57]. 5 gases emitted from the exhaust pipe Replicated copy number variations from genome wide studies are located on the following chromosomes: 1q21, 2p16.3 (NRXN1), 3p25-26 (CNTN4), 7q36.2 (DPP6), 15q11-13 (UBE3A, OR4M2, OR4N4);

16p11.2 (MAPK3, MAZ, DOC2A, SEZ6L2, HIRIP3, IL6); 22q11.2 [ 55]. However, some of these are also shown to be more frequently present in patients with schizophrenia and mental retardation than controls, thus raising questions about specificity to ASD [ 55]. Several studies have demonstrated that ASD reflects heterogeneous disorders whose etiology is linked with several rare monogenetic disorders such as fragile X syndrome, mutations in TSC1/TSC2, LAMB1, CNTNAP2, PTEN, DHCR7, SHANK3, NLGN3/4, or

2013 vaccination schedule for preschool children recommended by the U.S. electricity and magnetism study guide 5th grade Centers for Disease Control and Prevention167. Shaded boxes indicate the age range the vaccine can be given. Asterisks denote Al-adjuvanted vaccines. Hep A is given in 2 doses spaced at least 6 months apart. gas station car wash According to this schedule, by the time a child is two years of age, they would have received 27 vaccinations (3x HepB, 3x Rota, 4x DTaP, 4x Hib, 4x PCV, 3x IPV, 2x Influenza, 1x MMR, 1x Varicella and 2x HepA). Abbreviations: Hep A, hepatitis A; Hep B, hepatitis B; Rota, rotavirus; DTaP, diphtheria-pertussis-tetanus; Hib, Haemophilus influenzae type b; PCV, pneumococcal; IPV, inactivated polio; MMR, measles-mumps-rubella.

community, the notion that any compound in vaccines might be involved in the changing rates of ASD is sometimes taken as a form of apostasy. gas after eating dairy It is not our intention in the following to incite this concern, merely to show that Al has the neurotoxic capability and ubiquity to contribute to ASD in humans and that some of the features of the disorder can be demonstrated in animals treated with

With respect to Al in the vaccine adjuvant form, in the last decade, studies on animal models and humans have indicated that Al adjuvants have an intrinsic ability to inflict adverse neurological and immuno-inflammatory manifestations [ 91, 92, 117, 118]. This research culminated in delineation of ASIA-“autoimmune/inflammatory syndrome induced by adjuvants”, which encompasses the wide spectrum of adjuvant-triggered medical conditions characterized by

models [ 92, 120], and those associated with administration of adjuvanted vaccines in humans are neurological and neuropsychiatric [ 121, 122]. The ability of Al adjuvants to cross the blood-brain and blood-cerebrospinal fluid barriers [ 92, 109, 122, 123] may in part explain the reason the adverse manifestations following vaccinations tend to be neurological with an underlying immuno-inflammatory component [ 121, 124, 125]. Thus it appears that Al impacts on the CNS and immune system are not disparate

polymerase) [ 158]. These effects were experimentally demonstrated at physiologically-relevant Al concentrations (10-100 nm) [ 158, 161] and at levels that have been reported in Alzheimer disease patients’ chromatin fractions [ 162]. electricity drinking game Furthermore, Al content expressed per gram of DNA was found to be significantly increased in nuclear and heterochromatin fractions in

A: The effect of Al on the expression of 18 autism-related genes in the brains of Al-injected (n=3) and control (Con; n=3) male CD-1 mice. β-actin was used as the internal standard. B: Quantification of the expression change shown in A. The expression levels of 7 autism- and innate immunity-related genes were significantly altered in Al-injected mouse brains compared to saline control (Con) as measured by semi-quantitative RT-PCR analyses. Data are presented as fold difference as compared to controls. electricity history Histograms report the mean ±SEM of three independent experiments determined by densitometry. **p <0.01, *p <0.05. C: The protein levels of the 7 genes with altered expression levels after aluminum injection were verified by western blots. β-actin was used as internal standard.
