objective: urogynecologists are constantly looking for simple, safe and effective ways to cure vaginal apex prolapse. the aim of this study was to evaluate the results of posterior intravaginal slingplasty (pivs). materials and methods : a total of 38 patients with advanced vaginal apical prolapse underwent posterior intravaginal slingplasty in vali-e-asr hospital in tehran. in this clinical tr...

background in rhinoplasty, functional and cosmetic problems of the nose are corrected. these problems cause imbalance between the nasal subunit and face. throughout these deformities, there are 4 variants, so there is a need for careful preoperative evaluation either for treatment or prevention of the occurrence. according to functional and aesthetic effects of these variables in rhinoplasty, e...

a r t i c l e i n f o Keywords: Crepidula fornicata Habitat association Larval settlement Microhabitat Post-settlement mortality Recruitment Habitat-specific distributions of marine benthic invertebrates can be caused by several processes acting prior to, during or after settlement, including differential settlement and varying levels of mortality between habitat types following adaptation of t...

Human vaults are the largest cytoplasmic ribonucleoprotein and are overexpressed in cancer cells. Vaults reportedly function in the extrusion of xenobiotics from the nuclei of resistant cells, but the interactions of xenobiotics with the vault-associated proteins or non-coding RNAs have never been directly observed. In the present study, we show that vault RNAs (vRNAs), specifically the hvg-1 a...

Deep inside a mountain on the island of Spitzbergen within the Arctic Circle, the world's first Global Seed Vault was launched last month as the ultimate in safe repository for plant material from seed stores around the world that may be subject to climate change or other unpredictable catastrophies. Every nation has been invited by the Norwegian government to place seeds in its vault. The seed...

This paper investigates the existence and extent of economies of scale in depository and settlement systems. Evidence from 16 settlement institutions across different regions for the years 1993–2000 indicates the existence of significant economies of scale. The degree of such economies, however, differs by size of settlement institution and region. While smaller settlement service providers rev...

Coral settlement is a key ecological process in the maintenance, recovery and resilience of coral reef ecosystems. Coral reefs in the Persian Gulf survive in one of the world’s most extreme environments, yet there remains limited knowledge of the role of coral settlement considered critical for maintaining population dynamics. Spatial and temporal patterns of coral settlement were examined at 6...

For sessile marine invertebrates, processes contributing to larval release, dispersal, and settlement in favourable habitats are central to patterns of distribution and community structure. We quantified larval release patterns, phototactic behaviour, and settlement in response to environmental cues for the coral reef sponge Luffariella variabilis. Individual sponges released up to 830 larvae d...
