wildlife sancturies (w.s.) according to iucn classification need less conservation, but more development plan. lavandville w.s.: (less than 1000 ha, nw of iran) is located near caspian sea and !is important as habitats for waterfowl and other birds. physical resources (sands and oyster shells) of l.w.s. are exploited ; by local people. the area also provides outdoor .recreational apportunities ...

Probability distributions of human displacements have been fit with exponentially truncated Lévy flights or fat tailed Pareto inverse power law probability distributions. Thus, people usually stay within a given location (for example, the city of residence), but with a non-vanishing frequency they visit nearby or far locations too. Herein, we show that an important empirical distribution of hum...

OBJECTIVE To evaluate the aesthetic results in our initial group of patients treated with a combination of a midface-lift and fat transfer compared with a randomly selected group of patients who underwent a midface-lift without concurrent fat transfer by one of us. METHODS The setting was a private, ambulatory, surgical center. The design was a comparative study between patients who did or di...

Water resources management is one of the most important challenges to today's society. Functionally intact and biologically complex freshwater ecosystems provide many economically valuable commodities and services to society (ecosystem services), beyond simply direct water supply. Besides being an integral part of the ecosystem, water is also a social and economic good. It is therefore critical...

OBJECTIVES Since the introduction of video-assisted lobectomy for non-small-cell lung cancer (NSCLC) into clinical practice, it has been discussed controversially whether mediastinal lymphadenectomy can be performed as effectively as an open procedure via thoracotomy. Therefore, we address this issue in a prospective randomized trial conducted in our institution. METHODS In total, 66 patients...

Marginal zone cell lymphoma is a recently described entity among the non-Hodgkin's lymphomas. It likely originates from the marginal zone B cells in the spleen and equivalent cells in the lymph node and extranodal tissues. Recent evidence indicates that marginal zone B cells are functionally heterogeneous and may differ with respect to the pattern of somatic hypermutation in their Ig variable g...

Bone morphogenetic protein 4 (BMP-4) is expressed in the ventral marginal zone of the gastrulating embryo. At late gastrula stage this gene is expressed in the ventral-most part of the slit blastopore and in tissues that derive from it. At tailbud stages BMP-4 is expressed in the spinal cord roof plate, neural crest, eye and auditory vesicle. The interactions of BMP-4 with dorsal genes such as ...
