Tongue biting, traditionally believed to be a specific clinical sign favoring epilepsy, is also reported to occur in syncope and psychogenic seizures(2). Lateral tongue biting (on the sides) is more specific for a diagnosis of true epilepsy as compared to syncope(2) or psychogenic seizures, where biting of the lip or tip of the tongue is seen(3). Nocturnal tongue biting (NTB) can rarely be the ...

Tail biting in pigs is a widespread problem in intensive pig farming. The tendency to develop this damaging behaviour has been suggested to relate to serotonergic functioning and personality characteristics of pigs. We investigated whether tail biting in pigs can be associated with blood serotonin and with their behavioural and physiological responses to novelty. Pigs (n = 480) were born in con...

Tail-biting is a behavioral abnormality which compromises the welfare of pigs. The goal of this study was to characterize the tail-biting phenotype using behavior and measures of heart-rate (HR) and its variability (HRV) in pigs. Thirty pigs were categorized as tail-biters (n=10), tail-bite victims (n=10), and control pigs (n=10) based on the frequency of tail-biting behavior that they performe...

Use of repellents seems to be most reliable method of personal protection against annoyance and infections associated with haematophagous insects. We have investigated the biting activity of Simulium and tested the repellency of five essential oils extracted from Homalomena aromatica Schott (Alismatales: Araceae), Pogostemon heyneanus Bentham (Lamiales: Lamiaceae), Citrus aurantifolia Swingle (...

The purpose of this study was to clarify the genetic contribution to finger-sucking and nail-biting in childhood using the largest databases available on Japanese twins. The subjects were 1131 pairs of 12-year-old twin children, consisting of 1057 males and 1205 females. All data were gathered by maternal questionnaire, and responses to the questionnaire were checked in the medical interview. T...

The essential oil from aerial parts of Ruta chalepensis L. (Sapindales: Rutaceae) was obtained by hydrodistillation, and its chemical profile was identified using gas chromatography and gas chromatography-mass spectrometry. Compounds, 2-undecanone (43.2%), 2-nonanone (27.9%), and 2-nonyl acetate (10.6%) were the major constituents of the oil. Biting deterrent activity of R. chalepensis essentia...

The mosquito sampling efficiency of light-trap catches and electric motor mosquito catches were compared with that of human biting catches in the Three Gorges Reservoir. There was consistency in the sampling efficiency between light-trap catches and human biting catches for Anopheles sinensis (r = 0.82, P<0.01) and light-trap catches were 1.52 (1.35-1.71) times that of human biting catches rega...

The biting activity of Culex ribeirensis was studied in the highland region of Southern Brazil and compared with data previously obtained in a lowland area of the same region. Hourly sampling with human bait showed a bimodal pattern, with a greater peak in the evening crepuscular period. Behavior was similar in both the highland area of Lupo Farm and the lowland of the Ribeira Valley but with a...

Introduction: Stereotypic behaviors are characterized by repetitive, deviated and aimless actions that persist for more than 4 months in individual. Nail biting habit is one of informed obsessive-compulsive disorders that begins in childhood and continues for a long time. Onychophagia is a disorder with unknown cause and many factors can predispose it in a child. Individual characteristics and ...
