(збудниками Лайм-бореліозу) і B. hermsii та B. miyamotoi (збудниками кліщових поворотних лихоманок) працівників лісових господарств Тернопільщини, використавши двохетапну схему діагностики (ІФА та імуноблот), встановити клінічні прояви поєднаного перебігу цих бореліозів. Пацієнти і методи. Під спостереженням знаходилося 339 працівників 4 лісових (Бучацького, Кременецького, Тернопільського, Чортківського) і Бережанського лісомисливського господарств Тернопільської області. Обстежені мали вік від 20 до 65 років. Чоловіків було 330, жінок – 9. Антитіла до антигенів збудників комплексу B. burgdorferi s. l. у сироватці крові лісівників визначали методом імуноферментного аналізу (ІФА) з використанням тест-систем компанії Euroimmun AG (Німеччина). Зразки крові з проміжними й позитивними результатами першого етапу роботи досліджували методом імунного блотингу. Обстеження проводили в лабораторії Центру із вивчення Лайм-бор...

Accurate laboratory diagnosis of Lyme disease (Lyme borreliosis), caused by the spirochete (BB), ... more Accurate laboratory diagnosis of Lyme disease (Lyme borreliosis), caused by the spirochete (BB), is difficult and yet important to prevent serious disease. The US Centers for Disease Control and Prevention (CDC) presently recommends a screening test for serum antibodies followed by confirmation with a more specific Western blot (WB) test to detect IgG and IgM antibodies against antigens in whole cell lysates of BB. species related to BB cause tick-borne relapsing fever (TBRF). TBRF is increasingly recognized as a health problem in the US and occurs in areas where Lyme disease is prevalent. The two groups of share related antigens. We have developed a modified WB procedure termed the Lyme immunoblots (IBs) using recombinant antigens from common strains and species of the BB sensu lato complex for serological diagnosis of Lyme disease. A reference collection of 178 sera from 26 with and 152 patients without Lyme disease were assessed by WB and IB in a blinded manner using either crite...

Research paper thumbnail of Synthesis, Characterization, and Structures of a Persistent Aniline Radical Cation

Angewandte Chemie International Edition, 2012

All complexes were characterized by elemental microanalysis and by IR, 'H NMR, and mass spectroscopies. An X-ray analysis of (1) and (4) confirms the results of IR studies that these complexes contain N-bonded selenocyanate ligands. In molecules (1) and (4) there is a pseudotetrahedral arrangement about each titanium. The N-C-Se chains are linear with normal N-C and C-Se bond distances. The dimer (4) contains an approximately linear Ti-O-fTi bridge (angle 173.4') with a Ti-0 bond distance of 2.838 A. The structural results are compared with those in related compounds.

Research paper thumbnail of Changes in activation of alcohol expectancies in memory in relation to changes in alcohol use after participation in an expectancy challenge program

Experimental and Clinical Psychopharmacology, 2000

In the present study, 38 undergraduates completed a drinking measure and factor-based and memory model-based expectancy measures, before and after an expectancy challenge intervention designed to alter expectancies. Expectancies were mapped into memory network format with individual differences scaling and likely paths of activation were modeled with preference mapping. Results indicated that exposure to the expectancy challenge led to a change in likely activation of expectancies for men, but not for women. In the 30 days after the intervention, alcohol use among men decreased significantly but did not change among women. Therefore, changes in likely activation corresponded to changes in drinking. These findings support a memory model conceptualization of expectancy influence on drinking.
