Ultraviolet B radiation (UVB) activates mitogen-activated protein kinases (MAPK): p38, extracellular signal regulated (ERK), and c-Jun N-terminal (JNK) kinases in human skin cells. Human keratinocytes (KC) exposed to UVB secrete several cytokines (CK), among which the growth differentiation factor-15 (GDF-15) is augmented in inflammatory and aging processes and the granulocyte macrophage-colony stimulating factor (GM-CSF) is involved in cell proliferation, differentiation, and survival, and both CK have implications in skin carcinogenesis...

Chronic atrophic gastritis is a generally asymptomatic condition of great importance because it develops into gastric cancer in a number of patients. It is described as an atrophy of the gastric mucosa. There are two types of atrophic gastritis: a gastric body predominant type in patients with infection of Helicobacter pylori, and an autoimmune type, limited to the gastric body and fundus. The autoimmune type is quite rare and affects people of all ethnicities. Globally, H. pylori infection is very common and is considered a class I carcinogen due to the large number of patients who subsequently develop gastric cancer...

Environmental pollution has posed a major threat to flora as well as fauna for the past few decades. Industries release effluents into the environment which act as the major source of pollution. The hazardous effects of heavy metals released from these industries impact the soil and due to bioaccumulation of these compounds in the food chain, they ultimately result in a serious human health hazard. The concentration of metals like chromium (Cr), lead (Pb), nickel (Ni), cadmium (Cd), zinc (Zn), titanium (Ti), cobalt (Co), and several others in plants as well as in aquatic animals is above permissible limits according to the World Health Organization (WHO) and the Federal Environmental Protection Agency (FEPA) guidelines...

Parkinson's disease (PD) is the second most common neurodegenerative disease followed only by Alzheimer's disease and affects millions of people worldwide. Despite the plethora of preclinical and clinical studies, there is currently a paucity of therapeutic agents for PD that can promote neuroprotection. In addition, the therapeutic agents currently available only help with improvement of PD symptoms. Therefore, it is imperative to find new therapeutic avenues for PD patients to minimize the economic and social burden on the concerned families...
