Steamboat Geyser in Yellowstone National Park is the tallest active geyser on Earth and believed to have hydrologic connection Cistern Spring, a hydrothermal pool ?100 m southwest from vent. Despite broad scientific interest, rare episodic eruptions made it difficult study its eruption dynamics underground plumbing architecture. In response recent reactivation of Steamboat, which has produced m...

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...

We report a case of fixed drug eruption caused by fluconazole. A local provocation with 10% fluconazole test in petrolatum applied at the site of a previous lesion of fixed drug eruption reproduced the eruption clinically and histopathologically.

Background: Serious cutaneous eruptions caused by cytarabine are never reported in China. Methods: We admitted a 43-year-old man who was diagnosed with acute non-lymphocytic leukemia, and was given several chemotherapy regimens including cytarabine. And when FLAG regimens were given in the patient, the serious pustular eruption appeared. Results: After the treatment, cutaneous eruption was grad...

Eruption pattern of permanent teeth in Delhi boys was studied in 1800 well nourished children age 5-14 years. Relationship of height, weight and sexual maturity with eruption of teeth was calculated. Earliest teeth to appear were lower first molar (5.64 years) followed by lower central incisors (6.02 years), The sequence of eruption in maxilla was first molar, incisors-central then lateral, fir...

This article reviews the infrequently utilized treatment method of forced eruption and how it can serve as an alternative to the sacrifice of the natural root system. Forced eruption can preserve the natural root system and related periodontal architecture, resulting in years of additional service for the patient. It also can maintain adjacent tooth structure while retaining the option for futu...

Kaposi’s varicelliform eruption (KVE) is a typeof skin disorder caused mainly byherpes simplex virus (HSV) type 1 and2 and occasionally by coxsackie A 16 and vacciniavirus, which is commonly found in the second andthird decades of life. It is predominantly associatedwith atopic dermatoses. Therefore, it is also termedeczema herpeticum (EH) 1. Herein, we report acase of Kaposi’s varicelliform er...

Weather and predation constitute the two main factors affecting the breeding success of those Arctic waders whose productivity is highly variable over the years. We tested whether reproductive success is associated with the post-breeding condition of adults, in which in 'good' years (with warm weather, plentiful food and low predation pressure) the condition of breeders and their productivity i...

Background: Knowledge of the normal tooth eruption patterns is essential for the identification and appropriate treatment of deviations in eruption that may endanger physiologic development. A delay in time between the exfoliation of a deciduous tooth and the eruption of its permanent successor may be related to a disorder known as dental retention. This occurs when tooth eruption does not occu...

Previous studies suggest that primary tooth eruption (PTE) in preterm infants is related primarily to gestational age, but the impact of other neonatal factors has not been studied. In a prospective longitudinal study, the timing and sequence of PTE were documented by a pictorial PTE record completed by the parents and by frequent oral exams in 14 preterm infants whose first tooth erupted at < ...
