What does be stand for in engineering?

B.E. stands for Bachelor of Engineering.

What is FCD in construction?

An FCD is a document used to process a change to an assured Engineering design document. Once the FCD is approved by CRL and the Project Manager has instructed the change through a Project Managers Instruction (PMI), it is a valid design document.

What is FC in civil engineering?

f’c is the specified compressive strength of concrete using standard cylinders of six inches diameter and twelve inches height.

How does an FDC work?

The Fire Department Connection, also commonly known as the siamese connection, is an important component found on most sprinkler and standpipe systems. When a fire sprinkler system activates, the FDC provides a means for firefighters to connect hose lines to supplement the fire sprinkler system’s domestic water supply.

What does FDC stand for in aviation?

Flight Data Center (FDC) NOTAMs are mandatory issuances and require compliance. These include safety hazards stemming from instrument approach procedures and airway changes. Temporary flight restrictions (TFRs) are one example of an FDC NOTAM.

What does FDC stand for medical?

A combination drug or a fixed-dose combination (FDC) is a medicine that includes two or more active ingredients combined in a single dosage form.

What does FDC mean in text?

16) Technology, IT etc (20) FDC — Fragness Defence Clan. FDC — Forever Dropping Casualties.

What is a follicular dendritic cell?

Definition. Follicular dendritic cells (FDCs) are non-haematopoietic cells that are present in the B cell follicles of secondary lymphoid tissues.

What is the role of follicular dendritic cells?

Follicular dendritic cells (FDCs) have important functions in the selection of memory B lymphocytes during germinal center reactions (GCR). They present native antigens to potential memory cells, of which only B cells with high affinity B cell receptors (BCR) can bind.

Where are dendritic cells found?

Dendritic cells are found in tissue that has contact with the outside environment such as the over the skin (present as Langerhans cells) and in the linings of the nose, lungs, stomach and intestines. Immature forms are also found in the blood.

Why are follicular dendritic cells important?

Follicular dendritic cells (FDCs) are stromal cells residing in primary follicles and in germinal centers of secondary and tertiary lymphoid organs (SLOs and TLOs). There, they play a crucial role in B-cell activation and affinity maturation of antibodies.

What are the types of dendritic cells?

There is a great variety of DCs with different phenotypes and localizations that form a cellular system distributed throughout the body and that is responsible for immune-surveillance. DCs are classified into conventional DCs (cDCs), plasmacytoids (pDCs), and DCs derived from monocytes (mDCs) [1, 2].

What is the germinal center reaction?

The germinal center (GC) reaction is the basis of T-dependent humoral immunity against foreign pathogens and the ultimate expression of the adaptive immune response. 1-3 He named these structures with strong cell division germinal centers (GCs) under the assumption that they were the main origin of lymphocytes.

Where do we found follicular dendritic cells and Langerhans cells?

Follicular dendritic cells (FDCs) are cells of the immune system found in primary and secondary lymph follicles of the B cell areas of the lymphoid tissue. Unlike DCs, FDCs are not derived from the bone-marrow hematopoietic stem cell, but are of mesenchymal origin.

Where are Langerhans located?

Langerhans cells (LC) are tissue-resident macrophages of the skin, and contain organelles called Birbeck granules. They are present in all layers of the epidermis and are most prominent in the stratum spinosum.

What type of cell is a Langerhans cell?

dendritic cells

What is the reason why Langerhans cells are no longer classified as macrophages?

… However, classified according to developmental origin (ontogeny), they are considered a specialized subset of macrophages: they arise from embryonic precursors rather than bone marrow. Langerhans cells are long-lived in tissue and selfmaintain their population without replenishment (Doebel et al., 2017) . …

What is the deepest layer of the epidermis?

stratum germinativum

What do Langerhans cells secrete?

The islets of Langerhans contain alpha, beta, and delta cells that produce glucagon, insulin, and somatostatin, respectively. A fourth type of islet cell, the F (or PP) cell, is located at the periphery of the islets and secretes pancreatic polypeptide.

Where are macrophages found?

The macrophages occur especially in the lungs, liver, spleen, and lymph nodes, where their function is to free the airways, blood, and lymph of bacteria and other particles. Macrophages also are found in all tissues as wandering amoeboid cells, and the monocyte, a precursor of the macrophage, is found in the blood.

What are the two types of macrophages?

Two Types of Macrophages: M1 and M2 Macrophages.

How do macrophages kill?

The first line of immune defense against invading pathogens like bacteria are macrophages, immune cells that engulf every foreign object that crosses their way and kill their prey with acid. After enclosing it in intracellular membrane vesicles, a process called phagocytosis, macrophages kill their prey with acid.

Can macrophages kill viruses?

Macrophages have been shown to phagocytose virus particles and kill virus-infected cells and thus inhibit virus growth in vitro.

Is macrophage a virus?

Macrophages are innate immune cells which have a central role in detecting viral infections including influenza A and human immunodeficiency viruses. They are found in all parts of the body, and they constitute 5–15% of cells depending on tissue.

What is the strongest immune cell?

Immune cascade Two types of white blood cells — B and T cells — are incredibly powerful tools in the immune system’s arsenal. B cells crank out billions of individualized antibodies, which uniquely bind to specific antigens.
