We analyze a class of models for unequal crossover (UC) of sequences containing sections with repeated units that may differ in length. In these, the probability of an 'imperfect' alignment, in which the shorter sequence has d units without a partner in the longer one, scales like qd as compared to 'perfect' alignments where all these copies are paired. The class is parameterized by this penalt...

Manual dexterity declines with increasing age, however, the way in which inter-manual asymmetry responds to aging is unclear. Our purpose was to determine the effect of age and practice on inter-manual performance asymmetry in an isometric force pinch line tracing task that varied in difficulty within segments. Thirty right-handed participants, five males and five females in each of three age g...

IMPORTANCE Helicobacter pylori colonization contributes significantly to multiple disease states, but its role in the development of tonsillar infection is unclear. Understanding the causes of chronic tonsillitis is important in clinical decision making of this commonly treated disease. OBJECTIVE To assess the correlation between H pylori colonization of tonsillar tissue in chronic tonsilliti...

Neoangiogenesis and inhibition of apoptosis are two factors considered as major leading causes of tumorigenesis. NO, synthesized by NOS, plays an important role in tumour growth, dissemination and vascularization. Caspase-3 is an executive enzyme of apoptosis. The presented research work has been focused on the comparative evaluation of localization of the angiogenic and proapoptotic cytokines ...

OBJECTIVE We aimed to determine the incidence of abnormal pathological findings in the tonsils and/or adenoids of children undergoing tonsillectomy and/or adenoidectomy, and the incidence of tuberculosis of the tonsils and adenoids; suggest criteria to identify children at risk for adenotonsillar tuberculosis; and investigate the association between HIV and adenotonsillar abnormality, the cost-...

STUDY DESIGN A retrospective radiographic analysis. OBJECTIVE The aim of this study was to investigate the scoliosis curve patterns/features and magnetic resonance imaging (MRI) tonsillar ectopia characteristics in Chiari I malformation without syringomyelia (CMI-only). SUMMARY OF BACKGROUND DATA The development of scoliosis associated with a CMI typically has been ascribed to the presence ...

The palatine tonsils, localized in the oropharynx, are easily accessible secondary lymphoid tissue in humans. Inflammation of the palatine tonsils, local and chronic in case of chronic tonsillitis (CT) or acute in the presence of a peritonsillar abscess (PTA), ranks among the most common diseases in otolaryngology. However, the functionality of tonsillar immune cells, notably T-cells, in the co...

introduction: due to the complexity of facial asy-mmetry, the diagnosis of different aspects of asymmetry via conventional radiographs is not precise. in this study, we investigated findings of facial asymmetry by using cone- beam computed tomography (cbct) images. materials and methods: in this descriptive study, we evaluated cbct findings of 18 patients i.e. a group of 14 females and 4 males ...

A 16 year old women with Tangier disease in palatine tonsils is reported. She has recurrent sore throat. In physical examination the palatine tonsils are hypertrophied and has very yellowish points. The facial skin is yellowish  the skin of another areas of body is normal. After tonsillectomy the pathologist report Tangier disease in palatine tonsils.

OBJECTIVE Halitosis secondary to pathology of the palatine tonsils is considered airway (type 2) halitosis in the etiologic classification. Reports differ as to the proportion of objective halitosis complaints that have tonsillar etiology, with some giving this figure as 3%. Due to their immunologic role, even healthy tonsils usually possess some subclinical inflammation. The tonsil crypt syste...
