OBJECTIVE Considering that epidemiological studies show that suicide rates in many countries are highest in the spring when vitamin D status is lowest, and that low vitamin D status can affect brain function, we sought to evaluate if a low level of 25-hydroxyvitamin D [25(OH)D] could be a predisposing factor for suicide. METHOD We conducted a prospective, nested, case-control study using seru...

The most widely used indicator of vitamin D status is the measurement of 25-hydroxyvitamin D [25(OH)D] in either serum or plasma. Several studies have reported discrepancies between the results of assays used to measure 25(OH)D, however, which calls into question the ability of 25(OH)D assays to reflect accurately the vitamin D status of individuals. The National Institute of Standards and Tech...

CONCLUSION: MIDAS is suboptimal to describe disability in our patients due to a mean preoperative score of 102, as severe disability is defined as 21+. PSEQ successfully demonstrates extent of disability in this patient population and puts migraine surgery in perspective to other known pain treatments. It further evaluates functional outcome, rather than just improvement in symptoms. This signi...

Although the U.S. National Archives maintain the official audio recordings, for this paper we accessed the audio files in .mp3 format via the Oyez Project at the Chicago-Kent College of Law, which is a public repository that aims “to be a complete and authoritative source for all audio recorded in the Court since the installation of a recording system in October 1955.” To get additional informa...

Therac-25, a radiation treatment machine, massively overdosed 6 people because of a software error. In this paper we describe Therac-25 briefly then explain what went wrong in each of the 6 incidents. Then we analyze the responsibility of involved parties and show why these accidents happened. In the following sections we discuss the seriousness of software errors briefly and analyze safety eng...

The effect of incorporation of Si02 on the behavior of a TiO2-based photocatalyst prepared by a sol-gel technique from organometallic precursors is described. Application of photocatalysts with different TiOd Si02 ratios to the photodecomposition of rhodamine-6G (R-6G) demonstrates that a ratio of 30/70 produces a catalyst about 3 times more active than Degussa P-25 TiO2. Larger amounts of Si02...

Background: Animal and in vitro studies have shown that 25-OH vitamin D plays a significant role in different parts of body. Few data exist about the role of 25- OH vitamin D in reproduction. Insufficient levels during pregnancy are potentially associated with increased risk of preeclampsia, insulin resistance and gestational diabetes mellitus. Recently, few studies have assessed the prognostic...
