The quantity of volume or surface area of a CELL NUCLEUS.
Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)

Nuclear morphometry in columnar cell lesions of the breast: is it useful? (1/41)

AIMS: To evaluate the nuclear morphometric features of breast columnar cell lesions (CCLs) observed on mammotome core biopsies, to determine if there are significant measurable differences between those with atypia and those without. Correlation with follow-up open excision specimens was made. METHODS: Mammotome core biopsies performed on patients that contained CCLs were derived from the departmental case files. Histological material was reviewed and foci of CCLs demarcated for nuclear morphometric assessment, which was accomplished using an imaging system. Nuclear parameters studied were nuclear area and perimeter, circularity factor and feret's diameter. Statistical analysis used the GraphPad Prism software, with p<0.05 indicating significance. RESULTS: On examination of core biopsies of 40 patients with CCLs, 8 lesions were benign, 4 showed atypical lobular hyperplasia, 8 showed CCLs with nuclear atypia, 19 disclosed atypical ductal hyperplasia (ADH) and 1 showed ductal carcinoma in situ (DCIS). The nuclear area, perimeter and feret's diameter of CCLs with atypia were significantly greater than those without (p = 0.04, 0.03 and 0.019, respectively), whereas no difference was observed in the circularity factor. Follow-up open excision biopsy specimens in 24 patients showed upgrading to DCIS in 40% of cases diagnosed initially with ADH on core biopsy compared with 20% of CCLs with atypia. CONCLUSIONS: Nuclear morphometry in CCLs confirms nuclear size as the key parameter in the assessment of nuclear atypia. Whether it can be potentially used as an adjunctive tool depends on the establishment of appropriate cut-offs.  (+info)

Resistance to Alzheimer's pathology is associated with nuclear hypertrophy in neurons. (2/41)

This study focuses on the morphometric changes of neurons in asymptomatic Alzheimer's disease (AD), a state characterized by the presence of AD lesions in subjects without cognitive impairment. In autopsy brains, we used stereological methods to compare the cell body and nuclear volumes of anterior cingulate gyrus (ACG) and CA1 hippocampal neurons in asymptomatic AD subjects (n=9), subjects with AD dementia (AD, n=8), mild cognitive impairment (MCI, n=9), and age-matched controls (controls, n=9). In ACG, we observed a significant decrease in the neuronal volume of MCI and AD compared to controls; by contrast, no atrophy was present in asymptomatic AD. Moreover, we found a significant increase in nuclear volume in asymptomatic AD compared to controls (P<0.001), MCI (P<0.01) and AD (P<0.001) brains. Similar results were found in the CA1 region of the hippocampus. This nuclear hypertrophy may represent an early neuronal reaction to Abeta or Tau, or a compensatory mechanism which forestalls the progression of AD and allows the brain to resist the development of dementia.  (+info)

Nuclear swelling occurs during premature senescence mediated by MAP kinases in normal human fibroblasts. (4/41)

Excess thymidine induced premature senescence in normal human fibroblasts (TIG-7), with induction of typical senescence markers. Nuclear swelling, as well as cell swelling, was clearly observed in these senescent cells. Simultaneous addition of MAP kinase inhibitors, U0126, SB203580, and SP60025, effectively suppressed induction of premature senescence and senescence markers.  (+info)

Migratory localization of cyclin D2-Cdk4 complex suggests a spatial regulation of the G1-S transition. (8/41)

The association of the cyclin D-Cdk (DC) complex with retinoblastoma protein (pRb) is required for the G1-S transition of the cell cycle. Cyclin synthesis, nuclear localization and degradation are control mechanisms for the transition, but regulation of the DC complex nuclear import also contributes to the transition. Analysis of the timing of the G1-S transition in mammalian cell lines revealed acceleration with overexpression of cyclin D2 and Cdk4. Immunolocalization assays revealed that cyclin D2 and Cdk4 formed a complex in the cytoplasm and approached the nucleus. They accumulated on the cytosolic surfaces of the nuclear pores and then were arrested at the nuclear membrane before the nucleus reached a critical size. Finally, the complex was released into the nucleus and colocalized with pRb there, which led to pRb phosphorylation and DNA synthesis. The translocalization depended on the G1-S transition. In contrast, a truncated cyclin D2 that was not able to fully associate with Cdk4 lost the ability for release into the nucleus. This pattern of translocalization suggests a spatial separation of the cyclin D-Cdk complex from pRb and DNA in the nucleus to regulate the G1-S transition.  (+info)

The cell nucleus is a membrane-bound organelle found in the eukaryotic cells (cells with a true nucleus) that contains most of the cell's genetic material. The term "cell nucleus size" refers to the volume or diameter of this organelle. It can vary depending on the type and stage of the cell.

In general, the size of a nucleus is expressed as a ratio to the size of the cell, known as the nuclear-to-cytoplasmic ratio (N/C ratio). This ratio can provide important clues about the state and function of a cell. For example, cancerous cells often have larger nuclei and higher N/C ratios compared to normal cells.

It's worth noting that measuring the size of a nucleus can be challenging, as it is not always uniform in shape or easily distinguishable from other structures within the cell. Various techniques, such as microscopy and image analysis software, are used to accurately determine the dimensions of the nucleus.

The cell nucleus is a membrane-bound organelle found in the eukaryotic cells (cells with a true nucleus). It contains most of the cell's genetic material, organized as DNA molecules in complex with proteins, RNA molecules, and histones to form chromosomes.

The primary function of the cell nucleus is to regulate and control the activities of the cell, including growth, metabolism, protein synthesis, and reproduction. It also plays a crucial role in the process of mitosis (cell division) by separating and protecting the genetic material during this process. The nuclear membrane, or nuclear envelope, surrounding the nucleus is composed of two lipid bilayers with numerous pores that allow for the selective transport of molecules between the nucleoplasm (nucleus interior) and the cytoplasm (cell exterior).

The cell nucleus is a vital structure in eukaryotic cells, and its dysfunction can lead to various diseases, including cancer and genetic disorders.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

Poison Control Centers are specialized organizations that provide immediate, free, and expert advice and treatment recommendations for exposure to potentially harmful substances, also known as poisons. They are staffed by trained healthcare professionals, including medical toxicologists, nurses, pharmacists, and poison information providers. These centers manage a wide range of poisoning cases, from accidental ingestions in children to intentional overdoses and chemical exposures in adults. They offer 24/7 emergency hotline services to the public, healthcare providers, and first responders for poison-related emergencies and provide valuable resources for poison prevention and education. The primary goal of Poison Control Centers is to reduce the morbidity and mortality associated with poison exposures and promote overall public health and safety.

Skeletal muscle, also known as striated or voluntary muscle, is a type of muscle that is attached to bones by tendons or aponeuroses and functions to produce movements and support the posture of the body. It is composed of long, multinucleated fibers that are arranged in parallel bundles and are characterized by alternating light and dark bands, giving them a striped appearance under a microscope. Skeletal muscle is under voluntary control, meaning that it is consciously activated through signals from the nervous system. It is responsible for activities such as walking, running, jumping, and lifting objects.

The nuclear envelope is a complex and double-membrane structure that surrounds the eukaryotic cell's nucleus. It consists of two distinct membranes: the outer nuclear membrane, which is continuous with the endoplasmic reticulum (ER) membrane, and the inner nuclear membrane, which is closely associated with the chromatin and nuclear lamina.

The nuclear envelope serves as a selective barrier between the nucleus and the cytoplasm, controlling the exchange of materials and information between these two cellular compartments. Nuclear pore complexes (NPCs) are embedded in the nuclear envelope at sites where the inner and outer membranes fuse, forming aqueous channels that allow for the passive or active transport of molecules, such as ions, metabolites, and RNA-protein complexes.

The nuclear envelope plays essential roles in various cellular processes, including DNA replication, transcription, RNA processing, and chromosome organization. Additionally, it is dynamically regulated during the cell cycle, undergoing disassembly and reformation during mitosis to facilitate equal distribution of genetic material between daughter cells.

Organelles are specialized structures within cells that perform specific functions essential for the cell's survival and proper functioning. They can be thought of as the "organs" of the cell, and they are typically membrane-bound to separate them from the rest of the cellular cytoplasm. Examples of organelles include the nucleus (which contains the genetic material), mitochondria (which generate energy for the cell), ribosomes (which synthesize proteins), endoplasmic reticulum (which is involved in protein and lipid synthesis), Golgi apparatus (which modifies, sorts, and packages proteins and lipids for transport), lysosomes (which break down waste materials and cellular debris), peroxisomes (which detoxify harmful substances and produce certain organic compounds), and vacuoles (which store nutrients and waste products). The specific organelles present in a cell can vary depending on the type of cell and its function.

Erythrocytes, also known as red blood cells (RBCs), are the most common type of blood cell in circulating blood in mammals. They are responsible for transporting oxygen from the lungs to the body's tissues and carbon dioxide from the tissues to the lungs.

Erythrocytes are formed in the bone marrow and have a biconcave shape, which allows them to fold and bend easily as they pass through narrow blood vessels. They do not have a nucleus or mitochondria, which makes them more flexible but also limits their ability to reproduce or repair themselves.

In humans, erythrocytes are typically disc-shaped and measure about 7 micrometers in diameter. They contain the protein hemoglobin, which binds to oxygen and gives blood its red color. The lifespan of an erythrocyte is approximately 120 days, after which it is broken down in the liver and spleen.

Abnormalities in erythrocyte count or function can lead to various medical conditions, such as anemia, polycythemia, and sickle cell disease.
