Stem cells (SCs) are discovered long back but the idea that SCs possess therapeutic potential came up just a few decades back. In a past decade stem cell therapy is highly emerged and displayed tremendous potential for the treatment of a wide range of diseases and disorders such as blindness and vision impairment, type I diabetes, infertility, HIV, etc. SCs are very susceptible to destruction after transplantation into the host because of the inability to sustain elevated stress conditions inside the damaged tissue/organ. Heat shock proteins (HSPs) are molecular chaperones/stress proteins expressed in response to stress (elevated temperature, harmful chemicals, ischemia, viruses, etc) inside a living cell. HSPs protect the cell from damage by assisting in the proper folding of cellular proteins. This review briefly summarises different types of HSPs, their classification, cellular functions as well as the role of HSPs in regulating SC self-renewal and survival in the transplanted host. Applications of HSP modulated SCs in regenerative medicine and for the treatment of ischemic heart disease, myocardial infarction (MI), osteoarthritis, ischemic stroke, spinocerebellar ataxia type 3 (SCA3), leukemia, hepatic ischemia-reperfusion injury, Graft-versus-host disease (GVHD) and Parkinson's disease (PD) are discussed. In order to provide potential insights in understanding molecular mechanisms related to SCs in vertebrates, correlations between HSPs and SCs in cnidarians and planarians are also reviewed. There is a need to advance research in order to validate the use of HSPs for SC therapy and establish effective treatment strategies.

Pseudotumor cerebri (PTC), also known as idiopathic or benign intracranial hypertension, is characterized by elevated intracranial pressure without any evidence of organic central nervous system disorders. PTC is a rare but well-known adverse event associated with all-trans retinoic acid (ATRA) treatment. Persistent blindness in about 10% of affected patients is caused by PTC; therefore, prompt and accurate diagnosis is required. Recently, magnetic resonance imaging (MRI) findings, including empty sella, flattening of the posterior aspect of the globe, and distention of the perioptic subarachnoid space, have been found to be of high diagnostic value in PTC, but there apparently have been no reports about MRI findings in ATRA-induced PTC. We report here an 11-year-old boy with acute promyelocytic leukemia who developed ATRA-induced PTC during leukemia treatment. MRI findings beneficial for the diagnosis of PTC were observed.

Environmental pollutants, such as pesticides, herbicides, additives to food and water, and electromagnetic fields threaten public health by promotion of cancer, heart disease and chronic diseases of aging. Many of these pollutants cause adverse health outcomes by effects on mitochondrial function to produce oxidative stress through loss of the active site complex for oxidative phosphorylation, thioretinaco ozonide oxygen nicotinamide adenine dinucleotide phosphate, from opening of the mitochondrial permeability transition pore. Glyphosate, fluoride, and electromagnetic fields are examples of carcinogenic pollutants that promote loss and decomposition of the active site for oxidative phosphorylation, producing mitochondrial dysfunction and oxidative stress. Ionizing radiation has long been known to be carcinogenic, and non-ionizing electromagnetic fields from microwaves, radar, cell phones and cathode ray screens are carcinogenic and produce deleterious effects on capillaries, nerve cells, blood brain barrier, embryonic and germ cells, lenses and cardiac function. Adverse health effects of electromagnetic fields include cataracts, infertility, congenital malformations, cancer, lymphocytosis, leukemia, hearing loss, blindness, retinal hemorrhages, cardiac arrhythmias, dermatitis, hair loss, depression, memory loss, premature aging, heart attacks, and weaponized mind control. The hyperhomocysteinemia, suppressed immunity, and altered oxidative metabolism observed in atherosclerosis and dementia are attributed to deficiency of adenosyl methionine which results from increased polyamine biosynthesis by pathogenic microbes that are demonstrated in atherosclerotic plaques and cerebral plaques. Thus, environmental pollutants potentially promote diseases of aging, atherosclerosis, cancer, and premature aging by production of mitochondrial dysfunction.
