results 34 (34%) of the renal transplant recipients and 26 (26%) of the control group were positive for anti-toxoplasma igg. in addition 18 (18%) of the renal transplant recipients and 4 (4%) of the control group were positive for anti-toxoplasma igm. for both values of the antibodies, differences were statistically significant (p < 0.025 and p < 0.001 respectively). the pcr results indicated t...

conclusions the present study supported the contamination with t. gondii as a risk factor for schizophrenia just in women. results the analyses confirmed the significant differences between healthy women and ones with schizophrenia (p = 0.001) as well as between males and females with schizophrenia (p = 0.009) in igg positivity. materials and methods t. gondii igg antibodies of 100 patients wit...

background there are different types of aflatoxins, including aflatoxin m1, m2, g1, g2, b1 and b2 produced in the food chain, especially when the food is infected with fungi and can directly be consumed by humans. considering that our country is located in the subtropical geographic region where temperature and humidity ecological factors are among determining factors in contamination with afm1...

A rapid enzyme-linked immunosorbent assay (ELISA) where component incubation periods were shortened to one hour, was compared with agar gel double diffusion (AGDD) and a standard ELISA procedure for detecting antibodies to Aspergillus fumigatus in 28 asthmatic patients with suspected allergic aspergillosis. Using two A fumigatus antigens the rapid ELISA compared well with AGDD and the standard ...

A new generation biochip is described as capable of supporting high-throughput (HT), multiplexed enzyme-linked immunosorbent assays (ELISAs). These biochips consist of an optically flat, glass plate containing 96 wells formed by an enclosing hydrophobic Teflon mask. The footprint dimensions of each well and the plate precisely match those of a standard microplate. Each well contains four identi...
