From the eigenvalue equation (H0 + XV)\y/n (A)) = En (A) | y/„ ( /)) one can derive an autono­ mous system of first order differential equations for the eigenvalues En (A) and the matrix elements Vmn(X) = (ym(X) \ V\ i//n(X), where X is the independent variable. If the initial values En (X = 0) and y/n (A = 0) are known the differential equations can be solved. Thus one finds the “motion” of th...

Motor neurons, alone among neurons in the vertebrate CNS, extend axons out of the neural tube to innervate peripheral targets. Two classes of motor neurons, termed vMNs and dMNs, extend axons out of the neural tube via ventral and dorsal exit points, respectively, in accord with their homeodomain transcription factor repertoire. Downstream of these transcriptional codes, the cell surface recept...

Specific anatomical sites and pathways responsible for mediating metabolic and neuroendocrine effects of leptin are still poorly understood. Therefore, we examined distribution of leptin receptor-containing neurons transsynaptically connected with the porcine fat tissue by means of combined viral transneuronal tracing and immunohistochemical staining method. Pseudorabies virus (PRV) was injecte...

background and aims. reactive hyperplastic lesions of the oral connective tissue are associated with injuries of soft tissue and have high prevalence rates and different involvement patterns in different parts of the world. the aim of this study was to analyze demographic data of a university department. materials and methods. patient records of the department of oral pathology during a four-ye...

background: the clinical and pathological evaluation of oral lesions are very important in this field. the purpose of this study was to assess clinico- pathological agreement on 232 cases with oral lesion s.methods: the consecutive files of 232 patients with oral lesions from pathological laboratory archives of babol dental faculty and shahid beheshti hospital were reviewed and the data include...

abstract : inflammatory external root resorption (ierr) is a pathological phenomenon of microbial origin. this stu dy reports a case of external apical inflammatory root resorption of maxillary incisors associated with periradicular lesions in a 22 year old female, which was successfully treated by one-visit root canal therapy (rct). radiographic investigation revealed periapical radiolucencies...
