obesity is an important public health problem and major risk factor for postmenopausal breast cancer. adipose tissue is the major component involved in the control of the metabolism through energy homeostasis, adipocyte differentiation, insulin sensitivity and the activation of anti-inflammatory metabolic and immune pathways. leptin and adiponectin pathways are involved in proliferation process...

programmed cell death, which can be classified into apoptosis, autophagy, and oncosis, based on the cellular signalling pathways involved in the process, plays a critical role in cellular house-keeping. aberrant cell death regulation leads to body malformations, as well as to numerous diseases. here, we describe the effects of cytototoxins isolated from marine organisms on the various programme...

cancer stem cells (cscs) have been defined as a unique subpopulation in tumors, endowed with the capacity to initiate tumor progression, maintain self-renewal as well as metastatic potential. recently, more evidence strongly indicates the existence of cscs in solid tumors of wide variety of organs such as breast, brain and stomach. recent studies suggest that a special subpopulation of gastric ...

Objective(s): Biofilm formation is one of the most important factors in the development of infections caused by Staphylococcus aureus. In this study, the expression levels of genes responsible for biofilm formation were studied in methicillin sensitive and methicillin resistant S. aureus.Materials and Methods: A total of 100 meticillin-r...

Myocardial ischemia (MI) resulting in infarction is an important cause of mortality and morbidity worldwide. Acute ischaemia rapidly impairs myocardial contractile function. Myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. Hibernation is now thought to be...

The neurotransmitter glutamate interacts with glutamate receptor proteins, leading to the activation of multiple signaling pathways. Dysfunction in the glutamatergic signaling pathway is well established as a frequent player in diseases such as schizophrenia, Alzheimer disease, and brain tumors (gliomas). Recently, aberrant functioning of this pathway has also been shown in melanoma. In both gl...

calorie restriction through ingesting no or minimal amounts of food and caloric beverages for periods of time is called fasting. fasting can affect body through changing in physical and metabolic adaptations, as well as mineral and hormonal status. however, psychological effects and sometimes medical complications are likely in case of inappropriate fasting. fasting is associated with changes i...
