INTRODUCTION This study aimed to evaluate the prevalence of intestinal parasitosis and to identify risk factors associated therewith in hospitalized children. METHODS Three fecal samples from each patient were evaluated using three different techniques. The patients' nutritional and socioeconomic status and hematologic profiles were evaluated. RESULTS Of 106 children, 32.1% tested positive ...

Central nervous system organization of masticatory muscles determines the magnitude of joint and muscle forces. Validated computer-assisted models of neuromuscular organization during biting were used to determine organization in individuals with and without temporomandibular disorders (TMD). Ninety-one individuals (47 women, 44 men) were assigned to one of four diagnostic groups based on the p...

The study of host-parasite relationships involving vector-borne parasites requires understanding interactions between parasites and vectors. The capacity of haemosporidians to infect insects has clear evolutionary consequences for the transmission of diseases. Here, we investigated (i) the associations between blood parasites, biting midges and birds and (ii) the potential specificity between b...

Identification of biting lice species on the infected domestic chickens and their distribution on different body regions were studied at El-Beheira Governorate. Results showed two main species of biting lice on infected chickens; the chicken body lice, Menacanthus cornutus and the shaft lice, Menopon gallinae. Statistical analysis showed significance differences in the numbers of biting lice in...

Fingernail biting is a habit that is developed by numerous people, especially children and teenagers. Many clinicians believe that the habit of fingernail biting stems from nervousness or anxiety. Students, especially students with disabilities, can be easily distracted from instruction, can become the target of negative peer attention, and can get socially ostracized by habit problems such as ...

Indirect genetic effects (IGEs) are heritable effects of an individual on phenotypic values of others, and may result from social interactions. We determined the behavioural consequences of selection for IGEs for growth (IGEg) in pigs in a G × E treatment design. Pigs (n = 480) were selected for high versus low IGEg with a contrast of 14 g average daily gain and were housed in either barren or ...

Self-mutilation is a serious clinical problem. In humans selfmutilation is a characteristic of the Lesch-Nyhan syndrome and the de Lange syndrome. Several common drugs have been reported to produce self-biting in animals. The purpose of this project is to begin to de­ termine whether drug-induced self-biting in animals shares behavioral or biochemical characteristics with self-biting in the Les...

BACKGROUND Efficient malaria vector control requires knowledge of spatio-temporal vector dynamics. We have classified village groups according to the biting rate profiles of both Anopheles coluzzii and An. gambiae, the major malaria vectors in these villages. METHODS Mosquitoes were captured by human bait in 28 South Benin villages during 2009. Both An. coluzzii and An. gambiae counts in each...
