Threshold behavior in metastable dissociation of multi-photon ionized thymine and uracil [PDF]

open access: yes, 2017
Microsecond-timescale HNCO loss has been observed from single-color multi-photon ionized pyrimidine nucleobases in the gas phase. Photon energy thresholds for the metastable channels have been measured at 5.55 ± 0.02 eV for thymine and 5.57 ± 0.02 eV for

Programmed Cell Death and Postharvest Deterioration of Horticultural Produce [PDF]

open access: yes, 2010
Programmed cell death (PCD) is a process where cells or tissues are broken down in an orderly and predictable manner, whereby nutrients are re-used by other cells, tissues or plant parts.

Pressure induced nucleus DNA fragmentation [PDF]

open access: yesJournal of Assisted Reproduction and Genetics, 2011
The present study was designed to investigate the impact of pressure on nuclear DNA integrity in viable cells of mouse blastocysts.The blastocysts of hybrid F1 females [(C57Bl/10 J × CBA-H);N = 15] aged 2-3 months were exposed into the pressure impulse lasting ~0.021 s and characterized by a positive pressure peak of ~76 mmHg.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
