Human monoclonal antibodies show promise as treatment and prevention for influenza B

by

Researchers at Vanderbilt University Medical Center (VUMC) have made a significant breakthrough by isolating human monoclonal antibodies against influenza B. This virus is a notable public health threat, particularly affecting children, the elderly, and individuals with weakened immune systems. While seasonal flu vaccines provide coverage against both influenza A and B, they do not always … Read more

Developmental Biology: Processes from Fertilization to Organism Formation

by

Developmental biology is a fascinating field that explores the processes governing the growth, differentiation, and organization of cells into complex multicellular organisms. From the moment of fertilization, when a sperm cell fuses with an egg cell, to the formation of fully functional organs and tissues, developmental biology seeks to unravel the intricate molecular, cellular, and … Read more

Animal Physiology: Functions and Adaptations in Animals

by

Animal physiology is the branch of biology that focuses on understanding the biological functions and adaptations of animals, ranging from microscopic organisms to complex multicellular organisms. It encompasses a wide range of topics, including cellular processes, organ systems, homeostasis, metabolism, reproduction, behavior, and adaptations to diverse environments. By studying animal physiology, scientists gain insights into … Read more

Study reveals enzyme critical for maintaining stem cell function throughout life

by

Nothing lives forever, but compared to other cells in the body, hematopoietic stem cells (HSCs) are remarkably long-lived. HSCs are blood-forming cells—they give rise to rapidly dividing progenitor cells, which in turn generate hundreds of billions of cells to fulfill the daily demand of oxygen-delivering red blood cells, disease-fighting white blood cells and clot-forming platelets. … Read more

Physiology: Functions of Organ Systems

by

Physiology is the branch of biology that focuses on the study of the functions and processes of living organisms and their parts. It encompasses various levels of organization, from cells and tissues to organs and organ systems, and examines how these components work together to maintain homeostasis and support life. In this discussion, we’ll delve … Read more

New molecule shows promise in targeting SCLC cells and boosting immunity

by

A molecule has demonstrated its ability to kill tumor cells and incite an immune response in preclinical models of small cell lung cancer (SCLC), according to UT Southwestern Medical Center researchers. The findings, published in Nature Communications, could lead to more successful treatments for SCLC, one of the leading causes of cancer-related deaths in the … Read more

New method detects iron deficiency in skeletal remains

by

Diagnosing anemia in living people is typically a matter of a routine blood test. Retrospectively diagnosing anemia in people who died decades or even centuries ago is much more challenging since there is no blood left to test. Anthropologists at McMaster University and the University of Montreal, working with a hematologist colleague, have overcome that … Read more
