this study was conducted to determine regression equations for the prediction metabolizable energy value corrected for zero nitrogen retention (amen) in 12 wheat cultivars (mahdavi, chamran, sabalan, sepahan, sivand, alamoot, sholeh, neishaboor, pishtaz, bahar, shiraz and shahpasand) cultured in alborz province of iran. chromic oxide marker bioassay was used to determine wheat cultivars nitroge...

Responding to a preceding article by Michael J. Newton ("Moral dilemmas in surgical training: intent and the case for ethical ambiguity"), Downie comments on three of Newton's themes. He agrees that trainees should engage in ethical self-appraisal but cautions that introspection is inappropriate at the time of an operation. Regarding Newton's downplaying of philosophical analysis in medical e...

The structures of new antitumor antibiotics, calphostins (UCN-1028) A, B, C, D and I, which are specific and potent inhibitors of protein kinase C, were determined by spectral and chemical studies. All of the antibiotics have a 3,10-perylenequinone skeleton and calphostin D was revealed to be an antipode of isophleichrome.

We compute classical trajectories of Ultracold neutrons (UCNs) in a superconducting Ioffe-type magnetic trap using a symplectic integration method. We find that the computed escape time for a particular set of initial conditions (momentum and position) does not generally stabilize as the time step parameter is reduced unless the escape time is short (less than approximately 10 s). For energy in...

V-PYRRO/NO [O(2)-vinyl-1-(pyrrolidin-1-yl)diazen-1-ium-1,2-diolate] and V-PROLI/NO (O2-vinyl-[2-(carboxylato)pyrrolidin-1-yl]diazen-1ium-1,2-diolate), two structurally similar diazeniumdiolate derivatives, were designed as liver-selective prodrugs that are metabolized by cytochrome P450 isoenzymes, with subsequent release of nitric oxide (NO). Yet, their efficacy in the treatment of nonalcoholi...

The development of the mammary gland is unique: the final stages of development occur postnatally at puberty under the influence of hormonal cues. Furthermore, during the life of the female, the mammary gland can undergo many rounds of expansion and proliferation. The mammary gland thus provides an excellent model for studying the ‘stem/progenitor’ cells that allow this repeated expansion and r...
