Abstract— Human body tracking has a wide spectrum of applications. Examples include video surveillance, motion and activity capture for medical analysis, just to name a few. In this paper, a human skeleton model is proposed for human body tracking in video surveillance system. The skeleton model is based on 8 important body points namely; head, neck, shoulder, pelvis, knees and, ankles. Basical...

introduction: the objective of this study was to gather information about normal occlusion and arch dimensions in the primary teeth of the children belonging to an iranian population. methods: this descriptive cross-sectional study was performed on 68 children from the city of mashhad in the 3-5 age range. dental arch dimensions, interrelationships of primary canine and second molars, overbite ...

background and aims: inclusion body hepatitis (ibh) is one of the most important reemerging diseases in many countries with intensive poultry industries. in iran, the etiological agent of ibh (fowl adenovirus) has not been yet confirmed. the aim of this study was the molecular detection and identification of fowl adenovirus involving ibh in chicken flocks in iran. materials and methods: polymer...

To evaluate the diagnostic pitfalls attributing to false suspicious interpretation of papillary thyroid carcinoma (PTC), we performed a retrospective cytohistologic review of thyroid nodules diagnosed as suspicious for papillary carcinoma with histology-proven false suspicion of PTC. A total of 22 thyroid fine needle aspirates along with the corresponding surgical specimens were reviewed. The p...

We have studied a cohort of nemaline myopathy (NM) patients with mutations in the muscle alpha-skeletal actin gene (ACTA1). Immunoblot analysis of patient muscle demonstrates increased gamma-filamin, myotilin, desmin and alpha-actinin in many NM patients, consistent with accumulation of Z line-derived nemaline bodies. We demonstrate that nebulin can appear abnormal secondary to a primary defect...

Impaired nutrition of the intervertebral disc has been hypothesized to be one of the causes of disc degeneration. However, no causal relationship between decreased endplate perfusion and limited nutrient transport has been demonstrated to support this pathogenic mechanism. To determine the importance of endplate perfusion on solute diffusion into the nucleus pulposus and to show causality of en...

The aim of the study was to assess the intensity and distribution of galectin-3 expression in benign and malignant thyroid neoplasms by immunohistochemical method. Immunohistochemical expression of galectin-3 was analyzed in surgical thyroid specimens from 82 patients with histopathologic diagnosis of follicular adenoma (n = 32), Hürthle cell adenoma (n = 10) and papillary carcinoma (n = 40). R...

The Rev protein of human immunodeficiency virus type 1 (HIV-1) facilitates the nuclear export of unspliced and partially spliced viral RNAs. In the absence of Rev, these intron-containing HIV-1 RNAs are retained in the nucleus. The basis for nuclear retention is unclear and is an important aspect of Rev regulation. Here we use in situ hybridization and digital imaging microscopy to examine the ...

The salivary glands of the dipteran Chironomus tentans provide an elegant model system for the analysis of specific messenger ribonucleoprotein particles, the Balbiani Ring (BR) mRNP. BR mRNP particles contain long RNA transcripts of roughly 35-40 kb in size which possess a highly repetitive sequence. The diameter of the granular BR mRNP particles is around 50 nm and their geometry was meanwhil...

Intranuclear rods are aggregates consisting of actin and cofilin that are formed in the nucleus in consequence of chemical or mechanical stress conditions. The formation of rods is implicated in a variety of pathological conditions, such as certain myopathies and some neurological disorders. It is still not well understood what exactly triggers the formation of intranuclear rods, whether other ...
