This study investigated the developmental and nutritional programming of two important mitochondrial proteins, namely voltage dependent anion channel (VDAC) and cytochrome c in the sheep kidney, liver and lung. The effect of maternal nutrient restriction between early to mid gestation (i.e. 28 to 80 days gestation, the period of maximal placental growth) on the abundance of these proteins was also examined in fetal and juvenile offspring. Fetuses were sampled at 80 and 140 days gestation (term ~147 days), and postnatal animals at 1 and 30 days and 6 months of age. The abundance of VDAC peaked at 140 days gestation in the lung, compared with 1 day after birth in the kidney and liver, whereas cytochrome c abundance was greatest at 140 days gestation in the liver, 1 day after birth in the kidney and 6 months of age in lungs. This differential ontogeny in mitochondrial protein abundance between tissues was accompanied with very different tissue specific responses to changes in maternal food intake. In the liver, maternal nutrient restriction only increased mitochondrial protein abundance at 80 days gestation, compared with no effect in the kidney. In contrast, in the lung mitochondrial protein abundance was raised near to term, whereas VDAC abundance was decreased by 6 months of age. These findings demonstrate the tissue specific nature of mitochondrial protein development that reflects differences in functional adaptation after birth. The divergence in mitochondrial response between tissues to maternal nutrient restriction early in pregnancy further reflects these differential ontogeny’s.

The article analyses the 'ordinary' violence of revolutionary politics, particularly acts of gendered and sexual violence that tend to be neglected in the face of the 'extraordinariness' of political terror. Focusing on the extreme left Naxalbari movement of West Bengal, it points to those morally ambiguous 'grey zones' that confound the rigid distinctions between victim and victimizer in insurrectionary politics. Public and private recollections of sexual and gender-based injuries by women activists point to the complex intermeshing of different forms of violence (everyday, political, structural, symbolic) across 'safe' and 'unsafe' spaces, 'public' and 'private' worlds, and communities of trust and those of betrayal. In making sense of these memories and their largely secret or 'untellable' nature, the article places sexual violence on a continuum of multiple and interrelated forces that are both overt and symbolic, and include a society's ways of mourning some forms of violence and silencing others. The idea of a continuum explores the 'greyness' of violence as the very object of anthropological inquiry.
