in the present study the distribution of rubella hemagglutination inhibition (hi) antibody titer in the sera of 1486 women of 18 to 25 years old residing in tehran were examined. sera were pretreated with acid washed kaolin and pigeon red blood cell. titers below 1:10 and in some studies below 1:20 are considered nonimmune to rubella. our results show that 10, 29% of studied population had hi a...

Avian mycoplasmosis causes great economic losses to the poultry industry, and one of the major agents involved is Mycoplasma synovie (MS). Serum from commercial poultry breeders (n = 2781) was tested for MS by serum plate agglutination (SPA), hemagglutination inhibition (HI), and enzyme-linked immunosorbent assay (ELISA). From 2,781 samples tested, 736 (26.46%) were positive in SPA. From 712 SP...

A task set may need to be inhibited to facilitate the switch to another task. This event-related potential (ERP) study determined (1) whether backward inhibition (BI) is exerted preferentially in high interference environments, and (2) whether ERPs locked to critical time points reflect BI during cue preparation and/or response stages. High interference (HI) and low interference (LI) were creat...

BACKGROUND Screening tests are available to determine immunity to vaccine-preventable diseases, such as mumps and rubella. We aimed to define better assay for detecting immune status of health care personnel to vaccine-preventable diseases. METHODS Mumps and rubella antibodies of health care personnel at Shimane University Hospital were examined by hemagglutination inhibition assay (HI), comp...

BACKGROUND Hypoxia ischemia (HI) to the developing brain occurs in 1-6 in 1000 live births. Large numbers of survivors have neurological long-term sequelae. However, mechanisms of recovery after HI are not understood and preventive measures or clinical treatments are not effective. Poly(ADP-ribose) polymerase-1 is overactivated in response to ischemia. In neonatal mice HI activates PARP-1 but i...

An enzyme-linked immunosorbent assay (ELISA) and the hemagglutination inhibition (HI) test were used to evaluate the response of laboratory rats to experimental infection with pneumonia virus of mice. The ELISA procedure was more sensitive than the HI test and detected very low levels of antibodies early in the course of infection. At 5 days postinfection, ELISA detected antibody increases in f...

Hypoxia-ischemia (HI) can result in permanent life-long injuries such as motor and cognitive deficits. In response to cellular stressors such as hypoxia, tumor suppressor protein p53 is activated, potently initiating apoptosis and promoting Bax-dependent mitochondrial outer membrane permeabilization. The aim of this study was to investigate the effect of Trp53 genetic inhibition on injury devel...

Acute and convalescent plasma samples were obtained from 101 confirmed primary dengue cases: 48 cases infected with dengue virus type 1, 10 cases with type 2, 42 cases with type 3 and one case with type 4. The hemagglutination inhibition (HI) titers of individual samples were at levels similar to each of the 4 dengue viruses at both the acute and convalescent stages, irrespective of the dengue ...

Twelve monoclonal antibodies against Negishi virus were obtained and characterized by hemagglutination inhibition (HI) and neutralization (NT) tests using five flaviviruses isolated in the pan-Pacific region. The reaction pattern of the antibodies showed that Negishi virus was most closely related to Langat virus, followed by 3-Arch, JE and Apoi viruses in that order. Hemagglutinating (HA) anti...

Hypoxic ischemic (HI) injury in neonates damages brain tissues. We examined the mechanism of hyperbaric oxygen preconditioning (HBO-PC) in neonatal HI rat model. Seven-day-old rat pups were subjected to left common carotid artery ligation and hypoxia (8% oxygen at 37 degrees C) for 90 min. HBO (100% O(2), 2.5 atmospheres absolute for 2.5 h) were administered by placing pups in a chamber 24 h be...
