Apoptosis (from Ancient Greek ἀπόπτωσις “falling off”) is a form of programmed cell death that occurs in multicellular organisms.[2] Biochemical events lead to characteristic cell changes (morphology) and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global[vague] mRNA decay. The average adult human loses between 50 and 70 billion cells each day due to apoptosis.[3][a] For an average human child between the ages of 8 to […]

The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fueling brain function. However, if little carbohydrate remains in

Prevention of premature senescence requires JNK activation Premature senescence is considered as a cellular defense mechanism to prevent tumorigenesis. Although recent evidences show that c-Jun N-terminal kinase (JNK) is involved in the senescence process, the mechanism for this regulation is not fully understood. Here, we examined the role of JNK in premature senescence of tumor
