Abstract

An increase in the number of cells undergoing apoptosis was observed in the cingulate sulcus of newborn piglets 48 h after a global hypoxic-ischaemic insult. Apoptotic death was identified morphologically (by light and electron microscopy) and by DNA fragmentation, detected by in situ end labelling. The number of apoptotic cells was directly related to the degree of high-energy phosphate depletion during hypoxia-ischaemia, measured using continuous 31P magnetic resonance spectroscopy. These results may have implications for the understanding and treatment of perinatal hypoxic-ischaemic brain injury.

    Slight weight gain in some groups might be due to the tumor growth. Apoptosis and necrosis of cells could be preliminarily observed histologically by H&E staining [45]. To better evaluate the apoptosis and necrosis of tumors, tumor tissues were also evaluated qualitatively for Caspase 3 by immunohistochemistry.

    Considering that we evaluated only a specific time-point, collecting the samples after the memory task, we possibly missed the effect of maternal exercise on BDNF, and observe only the effect from behavioral task, which clearly increases BDNF levels associated with learning test [67–69]. In addition, some studies have shown that this neurotrophic factor protects against injuries caused by HI [46,70–73], being indicated even as a possible treatment against CNS damage. In summary, maternal exercise enhances recognition memory in a BDNF-independent pathway, a positive effect restricted to adult male offspring; highlighting the intrauterine metabolic programming that occurs in the fetuses and its long-lasting effects extended to the adulthood.

    The mechanism responsible for this alteration in cingulate sulcal structure remains unknown, but if cortical folding is driven by mechanical tension along long-distance axons (Van Essen, 1997), folding abnormalities may reflect altered patterns of connectivity in VPT children. This is consistent with the observation that hypoxia–ischemia, a known risk factor for brain injury in preterm infants (Dammann and Leviton, 1997; Greisen and Vannucci, 2001), produces an increased number of apoptotic cingulate neurons in piglets (Mehmet et al., 1994). The asymmetry of sulcal abnormalities in our findings are consistent with previous reports of anatomical asymmetries in medial cortical regions (Paus et al., 1996a,1996b; Thompson et al., 2010).
