Why Are Some Mammals More Resistant to Cancer? It’s a question that has puzzled scientists for decades, as cancer remains one of the leading causes of death worldwide. Yet, amidst the grim statistics, certain mammalian species stand out as remarkably resistant to this devastating disease. Understanding the secrets behind their resilience not only sheds light…
How Genes Affect Human Obesity is a topic of considerable interest and importance in the field of genetics and public health. While obesity is often attributed to lifestyle factors such as diet and exercise, growing evidence suggests that genetic predisposition plays a significant role in determining an individual’s susceptibility to weight gain and obesity-related complications….
Exercise and Cognitive Deficits are two interconnected aspects of overall health and well-being that have gained increasing attention in recent years. While cognitive deficits can impact various aspects of daily life, including memory, attention, and decision-making, exercise has emerged as a promising intervention for improving cognitive function. This article delves into the fascinating relationship between…
Does the Brain Produce New Cells? This question has long intrigued scientists and sparked debates in the field of neuroscience. Understanding whether the brain can generate new cells, particularly neurons, has profound implications for our understanding of brain function, development, and potential avenues for treating neurological disorders. In this article, we delve into the latest…
In the past decade, several types of viruses emerged from around the world. Some of these such as Covid-19 are already a reality that is leading to the loss of human lives and serious economic damages. Unfortunately, this epidemic is not the first nor the last one, and therefore, a better prevention system, new viral…
Gene therapy is a field of biology or medicine that focuses on introducing or replacing defective genes that are involved in the etiology of some genetic diseases. To introduce or replace defective genes, this approach involves using viral or non-viral vectors to insert healthy copies of genes into the cells of affected people to re-establish their normal…
The hallmark of Alzheimer’s disease (AD) is associated with the accumulation of “senile” plaques that are composed of amyloid-beta (Aβ) protein that surround neurons in affected regions. This accumulation results in loss of neurons in the hippocampus and cerebral cortex, leading to progressive cognitive decline such as memory defects. A connection between the brain and…
Stem cells are responsible for the generation of all tissues and organs within the body. When these cells become mutated at the gene level (DNA), they become cancerous and are named cancer stem cells [1]. These cancer cells are thought to provide resistance to chemotherapy and relapse in cancer patients. The mutations can affect embryonic…
Regenerative medicine is a therapeutic medical field that focuses on developing technologies that use stem cells to replace, engineer, or regenerate human or animal cells, tissues, or organs with the aim of restoring or establishing normal function. Stem cells have the capacity to self-renew and differentiate into different types of cells that are found in…
The gut flora is a heterogeneous population of micro-organisms that includes bacteria, fungi, and archaea, and that plays important role in the digestion and absorbance of food. Transplantation of fecal microbiota from younger mice (Donor) to older (Recipient) enhanced their health and lifespan (longevity). During the process of aging, the function of beneficial microbes, that…
