The aim of this study was to evaluate the effects of ovarian tissue vitrification and two-step in vitro culture on the metaphase II (MII) oocyte reactive oxygen species (ROS) level, mitochondrial transcription factor A (TFAM) expression and succinate dehydrogenase (SDH) activity. After collection of neonatal mouse ovaries, 45 ovaries were vitrified and the others (n = 45) were...

We further study the incidence relations that arise from the various subtowers, known as Baby Monsters, which exist within the R-Monster Tower. This allows us to complete the RV T class spelling rules. We also present a method of calculating the various Baby Monsters that appear within the Monster Tower. MSC Primary: 58A30 Secondary: 58A17, 58K50.

SN 2002kg is a type IIn supernova, detected in October 2002 in the nearby spiral galaxy NGC 2403. We show that the position of SN 2002kg agrees within the errors with the position of the LBV V37. Ground based and HST ACS images however show that V37 is still present after the SN 2002kg event. We compiled a lightcurve of V37 which underlines the variablity of the object, and shows that SN 2002kg...

We investigate the possibility to detect giant planets that are still embedded in young circumstellar disks. Based on models with different stellar, planetary, and disk masses, and different radial positions of the planet we analyze the resulting submillimeter appearance of these systems. We find that the influence of the planet on the spectral energy distribution could not be distinguished fro...

Of building cultural centers in all communities and with any kind of attitude has always been one of the designers’ issues. When we use the term in ordinary daily conversation, we often think of culture as an equivalent to the “higher things of the mind”- art, literature, music and painting. According to sociologists, the concept of culture includes such activities, but also far more. Culture c...

A 2-step roller culture system was designed that supported optimally the development of late-thirdstage larvae (L3) of Ascaris suum, obtained from rabbit lungs, to mature adults in vitro. The culture system consisted of 1) medium API-18 for 7 days, and 2) thereafter, medium API-1 supplemented with bovine hemin. Cultures were gassed with 85% nitrogen/5% oxygen/10% carbon dioxide and incubated at...

i ntroduction: apical debris extrusion (de) subsequent to root canal instrumentation, is one of the most important causes of endodontic flare-ups. the aim of this study was to compare the amount of de after root canal instrumentation using nickel-titanium (niti) hand files with step-back manual technique or installed on reciprocating handpiece. methods and materials: this study was conducted on...
