Types and frequency of ovarian masses in children over a 10-year period
Background: Ovarian masses represent a range of pathology from benign cyst to highly aggressive malignant tumors. It has been estimated that gynecologic malignancy account for approximately 2% of all types of cancer in children, 60-70% of these lesions arise in the ovary. Methods: All ovarian masses which were resected or biopsied in Mofid Children's Hospital from 2002 to 2012 were reviewe...

A retrospective study of children and adolescents oral and maxillofacial lesions over a 20-year period in Kerman, Iran
BACKGROUND AND AIM: Oral and maxillofacial lesions vary in different geographic regions based on their clinical features. Until now, few investigations have studied these lesions in children and adolescents in Iran. The aim of this research was to study the clinicopathological manifestations of biopsied oral and maxillofacial lesions among children and adolescents in the south of Iran.METHODS: ...
متن کاملYield Response of Spring Maize to Inter-Row Subsoiling and Soil Water Deficit in Northern China
BACKGROUND Long-term tillage has been shown to induce water stress episode during crop growth period due to low water retention capacity. It is unclear whether integrated water conservation tillage systems, such asspringdeepinter-row subsoiling with annual or biennial repetitions, can be developed to alleviate this issue while improve crop productivity. METHODS Experimentswere carried out in ...
متن کاملSolonetzic Soils of the Prairie Region
Soils of the Solonetzic Order account for about 7% of the agricultural land in Western Canada. They are most common in semi-arid regions (the Brown and Dark Brown soil zones) but occur as well in the Aspen Parkland and even under forest. They occur on parent materials containing sodium salts, or in lowland areas influenced by ground water discharge. Solonetzic soils are often referred to as cla...
