RD-flatness and RD-injectivity
It is proved that every commutative ring whose RD-injective modules are Σ-RD-injective is the product of a pure semi-simple ring and a finite ring. A complete characterization of commutative rings for which each artinian (respectively simple) module is RD-injective, is given. These results can be obtained by using the properties of RD-flat modules and RD-coflat modules which are respectively th...

I believe that the MCI is also trying to standardize exit exams, but we as a specialty and as the apex body of that specialty, should put together a standardized exit exam, to be passed by all can...
متن کاملEarly markers of retinal degeneration in rd/rd mice.
PURPOSE In the rd/rd mouse, the cell death of rod photoreceptors has been correlated to abnormal levels of the cyclic nucleotide cGMP within photoreceptors. Given that cGMP is required for opening of the cationic channels, there is the possibility that a high cGMP concentration would maintain these channels open, at a high energy cost for the retina. METHODS We investigated whether cation cha...

متن کاملp53 continues to surprise
As one of the most intensively studied transcription factors, it is unsurprising that p53 is involved in many biological processes, including cell cycle arrest, DNA repair, senescence and apoptosis.1 its activities are mainly regulated by posttranslational modifications and interactions with other cellular components. Over the past few years, p53 has also been linked to redox homeostasis, the b...
