introduction: aim of this study was to assess the association between prostate calcification in transrectalultrasound (trus) and sono- guided needle biopsy in prostate cancer (pca). methods: a cross-sectional study was performed on patients referred to imam khomeini hospital between 2005 and 2011 who underwent trus biopsy due to increased psa or abnormal dre. the serum levels of psa, prostate v...

our aiin has been to correlate animal experiments and investigations on man, the former serving as a basis for the latter, It is obvious that these two means, taken in conjunction, hold out the best hope for the discovery of the aetiology of dental disease and for the evolution of suitable methods for its elimination. It has been shownl 2 that normal, well-developed teeth are more resistant to ...

The effects of a bio-treatment on limestone (here tuffeau) is measured over a large number of dryingimbibition cycles. A model based on a space-dependent permeability coefficient is proposed. It leads to a non-linear diffusion model which accounts for the deviation from the standard Washburn model. Keyword: Limestone, bio-mineralization, water transfer, imbibition, non-linear diffusion

Mass coral bleaching affected large parts of the Great Barrier Reef (GBR) in 1998 and 2002. In this study, we assessed if signatures of these major thermal stress events were recorded in the growth characteristics of massive Porites colonies. In 2005 a suite of short (<50 cm) cores were collected from apparently healthy, surviving Porites colonies, from reefs in the central GBR (18-19°S) that h...

The radicular cyst is the most common inflammatory odontogenic in jaws. It a periapical lesion associated with non-vital teeth tooth-bearing regions of jaws slight male predilection. A typically asymptomatic, but if large or secondarily infected may cause swelling. usual radiographic appearance that radiolucent lesion. This case report documents rare 61-year-old mixed-density diagnosed as cyst....

STATEMENT OF PROBLEMS Dental age can be estimated on the basis of the tooth mineralization level during the developmental process of the teeth. Among various radiological methods reported for the dental age determination in children, Demirjian method is widely used. PURPOSE To evaluate the applicability of Demirjian method in age estimation of the children aged 7-15 years in Babol, a northern...

endocrine tumors of the pancreas (islet-cell tumors) are rare with neuroendocrine origin. the patient was a 41- year- old man, admitted with chief complains of epigastric mass feeling, dull abdominal pain, lack of appetite and weight loss up to 2-3 kg since 6 months ago. in physical examination, a mass was detected in epigaster and left upper quadrant (luq). in abdominal x-ray, a calcified mass...

BACKGROUND Dental age can be estimated based on the level of tooth mineralization during the developmental process. Various methods of determining chronological and radiographical stages have been used for dental age estimation. AIM To test the validity of the standards of dental maturation of Demirjian and Goldstein (Ann Hum Biol 3:411-421, 1976) when applied to Kuwaiti children. SUBJECTS ...

background/objective: hyperphosphatemia is the consequence of end stage renal failure. inadequate control of serum phosphorus results in elevated ca × p product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification.  in this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis pat...
