Brain Can Produce New Cells At the Age 90

For the first time, researchers have proven that the brain is capable of producing new nerve cells; even at the age of 90 and above. It was earlier believed that new cell production in the brain stops after a certain age and there is a rapid loss of neurons. Researchers believe that this finding could…

Sleep disruption

Sleep Quality Varies Throughout Menstrual Cycle

Young women are more likely to experience sleep disruption in the days leading up to their menstrual period; according to a new study that will be presented Saturday at ENDO 2019, the annual meeting of the Endocrine Society, in New Orleans, La. “Sleep is more disrupted in the several days directly prior to menses in…

Investigate Sleep's Role In Emotional Experiences For Teens

Researchers at the FIU Center for Children and Families are trying to uncover the role that sleep plays in processing emotional experiences, to improve treatments for youth with anxiety. The Emotional Memory Unification (EMU) study, led by FIU psychologist and Associate Professor Dana McMakin; is the result of a $3.6 million grant from the National…

Narcolepsy

Narcolepsy Is An Autoimmune Disease

Researchers from the University of Copenhagen have discovered autoreactive cells in persons suffering from narcolepsy. This is a new, important proof that the sleep disorder is an autoimmune disease. This knowledge may lead to better treatment of the chronic condition; the researchers behind the new discovery believe. For many years, scientists have expected the sleep…

Smell loss

An Ompaired Sense Of Smell Can Signal Cognitive Decline

The researcher often has problems with our ability to smell (called olfactory dysfunction). Older people might not able to identify an odour or differentiate one odour from another. In some cases, they might not able to detect an odour at all. Odour identification difficulties are common in people with neurodegenerative diseases; including Alzheimer’s disease. In…

Team Finds Key: Common Cancer Pathway

Scientists have long known that the protein p53, when mutated, is a critical factor in the onset of many different kinds of cancer. In its unmutated form, however, known to protect against cancer. These dueling qualities make the p53 protein and the gene that makes it among the most studied in biology, yet the molecular…

How Cells Obtain Energy From Cancer

The cell is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life. Cells are often the “building blocks of life”. The study of cells is called cell biology or cellular biology. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as…

Chronic insomnia

The Experience Of Sleeplessness More Visible

Some people with chronic insomnia think that they do not sleep during certain periods; whereas sleep measurements show that they do. Up till now, scientists have not able to pinpoint the exact causes of so-called ‘sleep misperception’. However, new research from Eindhoven University of Technology (TU/e); Kempenhaeghe Center for Sleep Medicine, Philips and Maastricht University…

Avocados

Seed Extract Shows Promise As Anti-Inflammatory Compound

An extract from the seeds of avocados exhibited anti-inflammatory properties in a laboratory study; it represents a potential source for novel anti-inflammatory compounds that could develop as a functional food ingredient; or pharmaceuticals. The researchers developed the extract over the last decade as a food colorant and it is not known whether the compounds responsible…

Mesenchymal stem cells

Osteogenic Differentiation of Mesenchymal Stem Cells

Osteogenic differentiation is a sophisticated and tightly regulated biological process. In response to specific stimuli, mesenchymal stem cells (MSCs) differentiate into osteoblasts; the bone-forming cells, through a multistep process characterized by four major phases: commitment toward the osteogenic lineage, osteoprogenitor cells proliferation; osteoblast maturation, and bone matrix mineralization. Induction of the differentiation process and progression…

T Cell Expansion

Regulation Of T Cell Expansion By Antigen

T cells are like the special ops forces of the immune system; detecting and killing infected cells. When a new threat is the cells ramp up from just a few sentry cells to a full platoon. But how does the immune system make just the right amount of T cells, when the starting populations of…

Mechanism Linked To Development Of Healthy Cells

The cell is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life. Cells are often called the “building blocks of life”. The study of cells is called cell biology or cellular biology. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.…
