The content of DNA, RNA and protein in cerebellum at different stages of the life span of rat as well as the ratios of protein to DNA, showed-that in this region extensive cell proliferation occurs between the 1st and 7th day after birth and once again between the ages of 225 and 750 days. The putative DNA degrading enzymes, acid and alkaline DNases, showed a positive correlation with the rapid DNA accretion noticed during developmental stages as well as during old age. From these results, it could be presumed that there was a second bout of glial cell multiplication in aging cerebellum and that DNases must be playing some important role in the process.

The effect of early postnatal undernutrition and subsequent rehabilitation on wet weight, DNA, RNA, protein and the activities of acid and alkaline DNases in the cerebellar region of rat brain was studied. The cerebellar region was found to be affected significantly during early undernutrition. Further, earlier the initiation of nutritional rehabilitation the better was the recovery and in some cases timely nutritional rehabilitation resulted in better than normal biochemical composition of the brain. The specific activities of acid and alkaline DNases were not affected by early undernutrition. However, the total activities of these enzymes were significantly low in undernourished rats (R115 and R21) Rehabilitation of these deprived groups upto 150 days resulted in higher amounts of these enzymes as compared to those of age-matched controls. It is concluded that the two DNases, are synthesized in a preferential manner during rehabilitation, It is further concluded that cerebellar region, in terms of development schedule and response to imposed calorie restriction, is intermediary between grey and white matter regions.

To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".
Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.
Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.
Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
