Psychological methods, 20(3), 293-309 (2014-11-18)
Publication bias threatens the validity of meta-analytic results and leads to overestimation of the effect size in traditional meta-analysis. This particularly applies to meta-analyses that feature small studies, which are ubiquitous in psychology. Here we develop a new method for

Gastroenterology, 96(5 Pt 1), 1274-1281 (1989-05-01)
Excellent clinical results have been reported with sclerotherapy for control of nonvariceal gastrointestinal hemorrhage. However, there are few controlled or comparative data on different sclerosing agents for treatment of lesions with active arterial bleeding or nonbleeding visible vessels. In a

[reaction: see text] In DMSO cleavage of triethylsilyl (TES) ethers by o-iodoxybenzoic acid (IBX) was significantly faster than cleavage of tert-butyldimethylsilyl (TBS) ethers or further oxidation into carbonyl compounds. In most cases, TES protecting groups could be removed in good

Preservation solutions for short-term storage of isolated donor corneas for use in penetrating keratoplasty have all been based on tissue culture medium, on the assumption that media designed to maintain the viability of cells at physiological temperatures will also provide

Human sperm karyotypes can be prepared after fusion of human sperm with Golden hamster oocytes. Most laboratories use one of two methods of sperm capacitation: incubation of freshly-ejaculated sperm in Biggers, Whitten, and Whittingham (BWW) medium for 5-7 h at
