Najnowsze techniki analgezji regionalnej obejmują niskodawkowe znieczulenie zewnątrzoponowe umożliwiające chodzenie pacjentek oraz kontrolowany przez pacjentkę wlew ...

Background and Objective: BRAF mutations were studied in various populations for prostate carcinoma (PC); however, mutations in BRAF gene are unusual compared to KRAS. Oncogenic activating of BRAF mutations were studied lately in almost 0%-10% of prostate cancer cases. Methods: In this retrospective study, we gathered 100 formalin-fixed ...

We argued in our Flexible Graphplan (FGP) work that the classical definition of the planning problem is too rigid to capture the full subtlety of many real problems. In light of this, we provided a new flexible definition and described a solution strategy based upon the Graphplan framework. Under this definition an action must determine how well its preconditions are met and assert a relative s...

purpose: to determine the association between norrie disease (nd) gene mutations and advanced stages of retinopathy of prematurity (rop) in premature neonates who were referred to farabi eye hospital, tehran, iran during 2005-2007. methods: fifty infants including 28 male and 22 female subjects with rop stage 3 or worse were enrolled in this case series. all three exons of nd gene underwent pol...

introduction: mucopolysaccharidosis i (mps-i) is an autosomal recessive lysosomal storage diseases, caused by α-l-iduronidase (idua) enzyme deficiency. the clinical manifestations of mps-i patients are variable ranging from severe to mild, and therefore prediction of disease severity is difficult. from when idua gene has been cloned more than 109 distinct mutations have been identified in it an...

We revisit the idea of road-wheel pairs, first introduced 50 years ago by Gerson Robison and later popularized by Stan Wagon and his square-wheeled tricycle. We show how to generate such pairs geometrically: the road as a roulette curve and the wheel as a pedal curve. Along the way we gain geometric insight into two theorems proved by Jakob Steiner relating the area and arc length of a roulette...

This project was funded by the Robert Wood Johnson Foundation, under the Changes in Health Care Financing and Organization (HCFO) initiative, grant number 29201. An earlier version of the paper was presented at the 1999 annual meeting of the Population Association of America. The authors are grateful to Linda Bilheimer, Pam Loprest, Stan Panis, Cori Uccello, Sheila Zedlewski, and especially Len...

One of Stan Changnon’s abiding interests is the frequency and pattern of large hail occurrence. Stan started publishing papers in AMS journals on the occurrence of large hail in 1966. After that initial effort, Stan has published 27 papers in AMS journals alone. When other journals, such as those of the AGU, Conference Preprints, and Technical Reports are added, Stan has an amazing record of do...
