Insulin-secreting cells report on insulin resistance February 22, Diabetes researchers at Sweden's Karolinska Institutet have developed a novel technique that makes it possible to monitor insulin resistance in a non-invasive manner over time in mice. The new method, presented in the journal Type 2 diabetes drug can exhaust insulin-producing cells February 11, Long-term use of liraglutide, a substance that helps to lower blood sugar levels in patients with type 2 diabetes, can have a deteriorating effect on insulin-producing beta cells, leading to an increase in blood sugar levels.

Cell biology (also called cytology, from the Greek κύτος, kytos, "vessel") is a branch of biology that studies the structure and function of the cell, which is the basic unit of life. Cell biology is concerned with the physiological properties, metabolic processes, signaling pathways, life cycle, chemical composition and interactions of. The DNA replicates in eukaryotic cells during the process of mitosis. The nucleus of eukaryotic cells is surrounded by an outer membrane called the nuclear envelope, which is a double-membrane structure consisting of two lipid layers similar to the cell membrane. Pores exist in the nuclear membrane, and the internal nuclear environment can therefore communicate with the cytoplasm of the cell. New data and research approaches have created opportunities for researchers to study in detail many aspects of cancer biology, including how the normal biological programs of cell proliferation and death are altered during cancer and how the immune system responds to tumors.

Steven Adie is pictured in his lab. Adie, assistant professor in the Meinig School of Biomedical Engineering, has come up with a way to use pressure from pulses of laser light to create sub-nanometer shifting of micron-sized particles embedded in soft tissue-like media.

The displacement of the particles is measured by a second beam in a process called photonic-force optical coherence elastography PF-OCE.

This technique has the potential to change how biomedical scientists study the relationship between cells and their environment, particularly when using engineered tissue cultures such as organoids.

The good thing about optical tweezers is they offer researchers the ability to control a single particle, or bead, with a highly focused beam of laser light. This unveils the mechanical response from a large number of randomly distributed beads in 3D.

The technique also allows for time-lapse 3D mechanical microscopy, something that was not possible using traditional methods such as atomic force microscopy, which is only useful for interrogating the 2D surface of a material.

The photothermal absorption-mediated heating response of the hydrogel to the laser light drowned out the signal they were seeking, which was the bead displacement.

This technique, Adie said, will be useful in studying the effect cells — including migrating cancer cells — have on their environment. Other contributors included Rishyashring Iyer, M.Since , CELLS alive!

has provided students with a learning resource for cell biology, microbiology, immunology, and microscopy through the use of mobile-friendly interactive animations, video, puzzles, quizzes and study aids.

1) General Biochemical and Biophysical Methods (Chapters ), 2) Analysis and Characterization of Proteins (Chapters ), 3) Immunological Methods (Chapters ), and 4) Nucleic Acids and Recombinant DNA (Chapters ). Many of the chapters correspond to the lectures. Embryonic stem cells that have proliferated in cell culture for six or more months without differentiating, are pluripotent, and appear genetically normal are referred to as an embryonic stem cell line.

At any stage in the process, batches of cells can be frozen and shipped to other laboratories for further culture and experimentation. Chapter 01 Biology and the Scientific Method 9 Biologists that study cancer are called oncologists.

Cancer seems to arise naturally in the cells of some animals. Cell biology (also called cytology, from the Greek κύτος, kytos, "vessel") is a branch of biology that studies the structure and function of the cell, which is the basic unit of life.

One common method of assessing cell proliferation looks at the entire DNA content in cells, either over time or as an endpoint assay. “DNA content assays give a convenient snapshot of cell number at a given time point to provide an easy proliferation assay,” says Stephen Oldfield, senior market development manager at Life Technologies. For example, the CyQUANT® assays from Life Technologies are .
