Best case scenario, the average shelf-life of vitamins is two years, Davis-Cadogan adds. There are some vitamins that come with special storage instructions, so it’s important to thoroughly read ...
As a cancer researcher who uses HeLa cells in my everyday work, even I sometimes find it hard to believe. ... On Aug. 1, 2023, over 70 years after doctors took Lacks’ cells without her consent ...
Epidemiologists have found evidence to suggest that long-term, high-dose supplementation with B6 and B12 may increase risk of developing lung cancer.
Erythrostimulating agents such as darbepoetin alfa or erythropoietin may be used to raise the red blood cell count. The mean duration of response to erythrostimulating agents is 8-23 months, and the response rate is about 39% (with a response defined as a 1 mg/dL rise in the hemoglobin level or a person not requiring a transfusion).

Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. [1] Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because ...
Cellular senescence is a phenomenon characterized by the cessation of cell division. [1] [2] [3] In their experiments during the early 1960s, Leonard Hayflick and Paul Moorhead found that normal human fetal fibroblasts in culture reach a maximum of approximately 50 cell population doublings before becoming senescent.
Disseminating cancer cells can proliferate or become dormant depending on the microenvironment and factors such as the ERK/p38 ratio. Dormancy is a stage in cancer progression where the cells cease dividing but survive in a quiescent state while waiting for appropriate environmental conditions to begin proliferation again. [1]
Kidney and nerve tissue cells can form memories much like brain cells, one new study has found. Another recent study says that memories of obesity stored in fat tissue may be partly responsible ...
