Introduced by C.R. Rao in 1945, the intraclass covariance matrix has seen little use in behavioral genetic research, despite the fact that it was developed to deal with family data. Here, I reintroduce this matrix, and outline its estimation and basic properties for data sets on pairs of relatives. The intraclass covariance matrix is appropriate whenever the research design or mathematical mode...
Domestic environmental pollution resulting from urban livestock farming was investigated in Makurdi using parasitological techniques. The test tube flotation technique was used for the parasitological analysis of animal faecal matter and soil samples collected from residential premises. Ectoparasitic fauna of dogs, goats, sheep and cattle cohabiting with humans within the same residential compo...
BACKGROUND Carotid angioplasty and stenting (CAS) is increasingly being used for treatment of symptomatic and asymptomatic carotid artery disease (CAD). To evaluate the efficacy of cerebral protection devices in preventing thromboembolic complications during CAS, we conducted a systematic review of studies reporting on the incidence of minor stroke, major stroke, or death within 30 days after C...
The effects of pyrimethamine-sulphadoxine (PS), chloroquine plus chlorpheniramine, a H1 receptor antagonist that reverses chloroquine resistance in Plasmodium falciparum in vitro and in vivo (CQCP), and amodiaquine plus pyrimethamine-sulphadoxine (AQPS) on gametocyte production were evaluated in 157 children with acute, symptomatic, uncomplicated falciparum malaria who were treated with these d...
OBJECTIVES School-based health centers (SBHCs) play an increasingly major role in providing mental health services for students. This study evaluated the impact of SBHCs on mental health-care services and psychosocial health-related quality of life (HRQOL). METHODS Four SBHC intervention and two matched non-SBHC school districts were examined from 1997 to 2003. The SBHC intervention began in ...
It is well known that there might be an epidemiological association between Helicobacter pylori infection and extraintestinal diseases. This study aimed at determining H. pylori infection in epileptic patients. Forty-seven cryptogenic epileptic patients (Group 1) and 35 healthy people (Group 2) participated in this study. Presence of H. pylori infection was examined by H. pylori stool antigen (...
An improvement of the trajectory matching algorithm is presented, which is based on the use of the derivative of trajectories and of the projection of experimental sinogram lines in the factor space determined by sinogram lines of projections of a model. The algorithm performance is illustrated by use of different phantom structures, to show the effect of symmetry on trajectory matching. A GroE...
The external ant community of Hospital Municipal de Morrinhos, in Morrinhos, Goiás State, was characterized by the low rates of richness, diversity, dominance and equity of species abundance. Pheidole sp.1, a polygynic species was numerically dominant in this environment, although it coexists with potentially competitive species. This ant species prevailed within all hospital departments and it...
BACKGROUND The aim of this study was to explore the curative effects cardiothoracic surgery (CTS) for critical patients in intensive care unit (ICU) using meta-analysis. METHODS Literature searched following search terms: surgery, unit, patients, post-operation, and effects. Rev Man 5.3 used RESULTS A total 15 randomized controlled trials (RCTs) were included, all which had a low risk bias, ind...
The aim of the study was to investigate the effects of chorioamnionitis on mortality and early onset neonatal sepsis (EONS) and bronchopulmonary dysplasia (BPD) in preterm neonates with birth weight < or = 1,500 g. The study included 395 preterm infants born at the Zagreb Clinical Hospital Center, from January 2001 to December 2005. All the placentas from preterm deliveries were sent for pathol...
