BACKGROUND AND AIM The localization of hepatitis B virus (HBV) core antigen to the nucleus or cytoplasm of hepatocytes has biological implications for viral packaging and persistence. This study examined the relationship between the localization of hepatitis B virus antigens, histological activity, and viral titer in patients with chronic HBV infection. METHODS Liver biopsies from 110 patient...

We have evaluated how levels of predictors of the cardiovascular risk such as: glucose, insulin, total cholesterol, high-density cholesterol, low-density cholesterol and triglycerides as well as adiponectin, fibrinogen, D-Dimers and CRP changed 24-28 weeks after treatment of hyperthyroidism in women with low and high titer of antibodies, and if their levels were different in these groups before...

rabies is acutely fatal encephalitis caused by a neurotropic virus. this virus belongs to the family ofrhabdoviridae and genus of lyssavirus. the virus is almost always transmitted to human through infectedmammalian saliva. rabies is inoculated to a wound by an infected animal bite. since infection is establishedin the cns, the outcome is almost always fatal. according to the outstanding role o...

Treatment for maternal syphilis with single-dose benzathine penicillin (2.4 million units intramuscularly) is being implemented in many parts of sub-Saharan Africa. To examine the effectiveness of this regimen, a prospective cohort of 1688 pregnant women was recruited in Tanzania. Birth outcomes were compared among women treated for high-titer (n=133; rapid plasma reagin [RPR] titer > or = 1:8 ...

BACKGROUND The prevalence of Toxoplasma gondii in free range chickens is a good indicator of the prevalence of T. gondii oocysts in the environment. The aim of this study was to isolate T. gondii parasites from heart and brain of seropositive free range (FR) chickens. FINDINGS Isolation of T. gondii from pooled heart and brain of 41 direct agglutination test (DAT) positive (≥1:40) free range ...

Because measles-specific antibody titer after vaccination is lower than after natural infection, there is concern that vaccinated persons may gradually lose protection from measles. To examine the persistence of vaccine-induced antibody, participants of a vaccine study in 1971, with documentation of antibody 1-7 years after vaccination, were followed up in 1997-1999 to determine the presence an...

We studied the usefulness of repeated enzyme-linked immunosorbent assay testing for heparin-induced thrombocytopenia (HIT) when the initial test result was negative and sought to determine whether the titer of the initial negative result correlated with the likelihood of obtaining a positive test result in repeated testing. We divided 150 patients who underwent HIT testing into 3 groups (50 pat...

Termite queens are highly specialized for reproduction, but little is known about the endocrine mechanisms regulating this ability. We studied changes in the endocrinology and ovarian maturation in primary reproductive females of the dampwood termite Zootermopsis angusticollis following their release from inhibitory stimuli produced by mature queens. Winged alates were removed from their natal ...

This study was undertaken to determine if impaired neutrophil (polymorphonuclear leukocytes [PMNL]) function is associated with an elevated Candida antigen titer after injury. PMNL from eight severely injured adults with Candida antigen titers of > or = 1:4 (titer positive) were evaluated for the ability to inhibit growth of Candida albicans in vitro by using a [3H]glucose incorporation assay. ...
