BACKGROUND Q fever caused by Coxiella burnetii is transmitted to humans by inhalation of aerosols from animal birth products. Q fever in pregnancy is suspected to be a potential cause of fetal and maternal morbidity and fetal mortality but the pathogenesis is poorly understood, and even in Q fever endemic areas, the magnitude of a potential association is not established.We aimed to examine if ...
background : the aims of this study were to determine the seroprevalence of canine ehrlichiosis and risk factors of this disease in companion dogs’ population of mashhad, north east of iran. canine monocytic ehrlichiosis (cme) is a zoonotic disease transmitted by ticks, rhipicephalus sanguineus, and caused by an obligate intracellular bacterium, ehrlichia canis. methods : during september 2009 ...
We present the discovery of a distant methane dwarf, the first from the Institute for Astronomy (IfA) Deep Survey. The object (“IfA 0230-Z1”) was identified from deep optical I and z-band imaging, being conducted as an IfA-wide collaboration using the prime-focus imager Suprime-Cam on the Subaru 8.2-m Telescope. IfA 0230-Z1 is extremely red in the IzJ (0.8–1.2 μm) bands but relatively blue in J...
AIM To assess the predictive value for chronic autoimmune gastritis (AIG) of the combined assay of anti-parietal-cell antibodies (PCA), anti-intrinsic-factor antibodies (IFA), anti-Helicobacter pylori (Hp) antibodies, and measurement of blood gastrin. METHODS We studied 181 consecutive patients with anemia, due to iron deficiency resistant to oral replacement therapy or to vitamin B12 deficie...
Injection of autoantigens in IFA has been one of the most effective ways of preventing experimental, T cell-mediated, autoimmune disease in mice. The mechanism that underlies this protection has, however, remained controversial, with clonal deletion, induction of suppressor cells or of type 2 immunity being implicated at one time or another. Using high resolution enzyme-linked immunospot (ELISP...
BACKGROUND Recommendations regarding the administration of imported fire ant whole body extract (IFA WBE) combined with aeroallergens or environmental allergens in a single immunotherapy injection are lacking. OBJECTIVE To evaluate the degradative effect of IFA WBE on cat, ragweed, Dermatophagoides pteronyssinus, and timothy grass allergens. METHODS Imported fire ant whole body extract was ...
The QUANTA Flash(®) CTD Screen Plus is a chemiluminescent immunoassay (CIA) for the detection of the major antinuclear antibodies (ANA) on the BIO-FLASH(®) platform. NOVA View(®) is an automated fluorescence microscope that acquires digital images of indirect immunofluorescent assay (IFA) slides. Our goal was to evaluate the clinical performance of the two automated systems and compare their pe...
Municipal solid waste (MSW) incineration fly ash (IFA) can be potentially reused as a substitute for some raw materials, but treatment for detoxification is indispensable owing to high contents of heavy metals in fly ash. In the present work, due to excessive leaching concentration of lead (Pb), a moderate thermal treatment with sodium hydroxide (NaOH) addition was employed to stabilize Pb in I...
Aim-To compare the techniques and results of a nested PCR and an immunofluorescence assay (IFA) for the detection of Pneumocystis carinii infection; to consider the role of the nested PCR in the diagnosis of P carinii pneumonia (PCP).Methods-Serial dilutions of two known P carinii positive samples were tested by IFA and PCR to determine their relative sensitivities. Seventy eight respiratory sa...
Antigen-mediated stimulation of thymidine incorporation was demonstrated in lymph node cells from guinea pigs immunized with 100 microg human serum albumin in either Freund's incomplete or Freund's complete adjuvant. Animals receiving HSA in IFA exhibited both cutaneous basophil (Jones-Mote) hypersensitivity and lymphocyte stimulation at 1, but not at 6 wk after immunization. Significant stimul...
