Tooth eruption is a localized process in the jaws which exhibits precise timing and bilateral symmetry. It involves resorption and formation of bone on opposite sides of the erupting tooth and these activities depend on the dental follicle, a thin connective tissue investment of the developing and erupting tooth. Biochemical studies have shown that during eruption cells, proteins and enzymes ch...

Post-admission hematoma expansion in patients with intracerebral hemorrhage (ICH) comprises a simultaneous major clinical problem and a possible target for medical intervention. In any case, the ability to predict and observe hematoma expansion is of great clinical importance. We review radiological concepts in predicting and observing post-admission hematoma expansion. Hematoma expansion can b...

Ectopic eruption into the dental environment is common, whereas eruption into other sites is rare. Diverse anatomical locations such as the mandibular condyle, coronoid process, palate, maxillary sinuses and nasal cavity can infrequently be the site of ectopic tooth eruption. One of the nondental sites for ectopic eruption is the maxillary sinus. Here, we present a case of dentigerous cyst with...

Objective: To determine the chronological eruption parameters of primary teeth in Indian children. Study Design: A longitudinal study consisting of 135 healthy children (74 boys and 61 girls) attending three child health centres in the city of Hyderabad, India were randomly selected and followed from the emergence of the first to the last tooth. Ages and order of tooth eruption were studied for...

Multi-model simulations show a post-Pinatubo eruption sequence of Pacific sea surface temperatures (SSTs) that includes a La Niña-like pattern the third northern winter after an eruption, opposite in sign to what was observed after Pinatubo. This leads to the loss of hindcast skill for years in the 1990s affected by the Pinatubo eruption because the post-eruption internal variability of the cli...

Damavand volcano is located 60 km to the East North- East of Tehran. It is a dormant stratovolcano outcrop in the Alborz Mountains of northern Iran and is the highest mountain (5670 m) in the Middle East and West Asia. Mazandaran Province, one of the most populous provinces by population density, Semnan and Gorgan provinces further east are neighbours of the Damavand. Volcanism in Damavand goes...

SHIMADA, Y., KASUKAWA, Y., MIYAKOSHI, N., HONGO, M., ANDO, S. and ITOI, E. Chronic Subdural Hematoma Coexisting with Ligamentum Flavum Hematoma in the Lumbar Spine: A Case Report. Tohoku J. Exp. Med., 2006, 210 (1), 83-89 ── We present a case of a chronic spinal subdural hematoma combined with a ligamentum flavum hematoma in the lumbar spine treated surgically. An 83-year-old woman receiving an...

The aim of the present paper is to determine the beginning, order, median time, termination, dynamics, continuity and intensity of the permanent tooth eruption, as well as its calendar, in a sample of Zagreb children. The study included 2768 children (1398 boys and 1370 girls). All subjects were classified in one-year age groups. The continuity of tooth eruption occurs from 5.1 years to 14.97 y...
