Calorie Restriction to Extend Human Life

Calorie restriction consists in reducing the average daily caloric intake below what is typical or habitual, without malnutrition or deprivation of essential nutrients. In a fasting diet, a person does not eat at all or severely limits intake during certain times of the day, week, or month. In a new study published in the journal […]

The Use of Platelet-rich Plasma in Dentistry

The use of platelet-rich plasma (PRP) extends to more than just the general medical field. In dentistry is also an emerging field of medicine involving stem cell technology, tissue engineering, and dental science.  PRP is prepared from autologous plasma with concentrated platelets, because they contain more than 300 biologically active molecules that are released upon […]

New Cancer Therapy Enhances Immune Response to Fight Cancerous Cells

In a recently published study researchers found that a form of Chimeric antigen receptor (CAR) T-cell cancer treatment, a type of immunotherapy, was effective in treating leukemia patients. The treatment kept two leukemia patients in remission for 10 years.  The results of the study were published in the journal Nature. CAR T-cell therapy is a […]

New Test Might be Able to Detect Lung Cancer at Early-stages

Lung Cancer  Lung cancer continues to be the leading cause of cancer mortality, and like in many other cancers the early detection is key to improve survival. Unfortunately there are no reliable blood-based tests available for early-stage lung cancer diagnosis.  One test commonly used for screening of lung cancer is low dose computed tomography, but […]

Injectable Hydrogel-mediated Delivery for Adipose-derived MSCs

In a recently published study, researchers from the University of Connecticut have developed a biomimetic injectable hydrogel using amnion membrane (AM) which can self-assemble in situ and retain the stem cells at the target site. The researchers evaluated the hydrogel and its efficacy in intraarticular injections, using a rat model. The hydrogel was evaluated with […]

Is Oversleeping Bad for Your Health?

The effects of sleep deprivation and how it can affect our health in multiple areas including cognition, physiological, and physical is an extensively studied subject. But according to studies both short sleep, which is considered to be less than 6 hours, and long sleep, more than 8 hours can cause unfavorable health outcomes.  What is […]

Even Mild Exercise Improves Memory Function According to a Study

In a research published in the journal Proceedings of the National Academy of Sciences, researchers from the University of California, Irvine and Japan’s University of Tsukuba found that even very light workouts can increase the connections between some parts of the brain that intervene in the formation and storage of memories. Physical exercise has beneficial […]

Healthy Weight Reduces Risk of Colorectal Cancer

Colorectal cancer is a disease in which cells in the colon or rectum grow out of control. Sometimes abnormal growths, called polyps, form in the colon or rectum. Over time, some polyps may turn into cancer. Also colorectal adenomas that persist and grow for long periods can become malignant.  Not counting some kinds of skin […]

Vitamin D Deficiency Associated with Higher Risk of COVID-19 Infection and Severity

The coronavirus disease 2019 (COVID-19) continues to spread around the globe since being declared a pandemic by the WHO in March 2020, causing significant morbidity and mortality.  SARS-CoV-2 infection rate has been reported to be higher in countries with low vitamin D and patients with low vitamin D. This vitamin is present in various types […]

What Source of Stem Cells Is Better?

Mesenchymal stem cells (MSCs) can be found in many adult tissues and are an attractive stem cell source for the regeneration of damaged tissues in clinical applications because they are characterized as undifferentiated cells, able to self-renew with a high proliferative capacity and that possess differentiation potential. Although bone marrow (BM) has been the main […]
