Analyzing How Skinfold Thickness Affects Log-Transformed EMG Amplitude-Power Output Metrics.

Background: The purpose of this study was to determine whether accounting for skinfold thickness would reduce the variability observed on a subject-by-subject basis for the -intercept and slope terms derived from the log-transformed EMG amplitude-power output relationship. We hypothesized that using skinfold thickness as a covariate would reduce the subject-by-subject variability in the -intercept and slope terms and, therefore, indicate potential mean differences between muscle groups.

Methods: Subjects had the skinfold from their three superficial quadriceps femoris muscles measured and then EMG electrodes placed over the three muscles.

Hyperbaric oxygen as an adjunct in zygomycosis: randomized controlled trial in a murine model.

Zygomycosis was induced by injecting CD-1 mice with 5 mg of intraperitoneal deferoxamine and then 10(6) CFU of intravenous and intrasinus Rhizopus arrhizus. The addition of hyperbaric oxygen (2.0 atm absolute twice daily) to amphotericin B did not improve survival over that achieved with amphotericin B and placebo air treatments.

Intravascular lymphomatosis: contribution of cerebral MRI findings to diagnosis.

Intravascular lymphomatosis (IL) is a rare variant of non-Hodgkin's lymphoma with an unusual predilection for the central nervous system (CNS). Most cases are not diagnosed until postmortem because of variable clinical presentation and nonspecific laboratory findings. Neuroimaging findings vary widely and range from diffuse involvement of the deep white matter to infarct-like lesions.

Status of the NASA SETI Sky Survey microwave observing project.

The Sky Survey observing program is one of two complementary strategies that NASA plans to use in its microwave Search for Extraterrestrial Intelligence (SETI). The primary objective of the Sky Survey is to search the entire sky over the frequency range 1000-10,000 MHz for evidence of narrow band signals of extraterrestrial, intelligent origin. Spectrum analyzers with upwards of 10 million channels and data rates in excess of 10 gigabits per second are required to complete the survey in less than 7 years.

Mild and moderate endometriosis. Comparison of treatment modalities for infertile couples.

A series of 1,268 consecutive patients with stage I and II endometriosis (American Fertility Society classification) were treated for the disease. In 675, no other factors contributed to their infertility. Among these patients, with no problems other than mild endometriosis, 57% (16/28) became pregnant when treated expectantly, 54% (51/95) after being treated medically, 47% (9/19) after laparoscopic cautery treatment, 81% (147/181) after laparoscopic laser treatment and 84% (97/116) after conservative surgery (laparotomy).
