Serum globulins that migrate to the gamma region (most positively charged) upon ELECTROPHORESIS. At one time, gamma-globulins came to be used as a synonym for immunoglobulins since most immunoglobulins are gamma globulins and conversely most gamma globulins are immunoglobulins. But since some immunoglobulins exhibit an alpha or beta electrophoretic mobility, that usage is in decline.

One of the types of light chains of the immunoglobulins with a molecular weight of approximately 22 kDa.
A technique that combines protein electrophoresis and double immunodiffusion.

The structure of an entire noncovalent immunoglobulin kappa light-chain dimer (Bence-Jones protein) reveals a weak and unusual constant domains association. (1/179)

Monoclonal free light chains secreted in immunoproliferative disorders are frequently involved in renal complications, including a specific proximal tubule impairment, Fanconi's syndrome. The latter is characterized in most cases by intracellular crystallization including a light-chain variable-domain fragment which resists lysosomal proteases. Bence-Jones protein (BJP) DEL was isolated from a patient with myeloma-associated Fanconi's syndrome. The crystal structure of this human kappa immunoglobulin light-chain noncovalent dimer was determined using molecular replacement with the structure of molecule REI, as the variable domain, and that of BJP LOC as the constant domain. To our knowledge, DEL is the first complete kappa BJP structure described to date. The R-factor is 20.7% at 2.8 A resolution. The BJP DEL dimer was compared with other light-chain dimers and with Fab fragments with a kappa light chain. Although the domain-folding pattern was similar, the relative positions of the constant domains differed. BJP DEL showed a noncanonical quaternary structural arrangement which may be attributable to the poor CL-CL affinity and lack of an interchain disulfide bridge, combined with the conformational editing effect of the crystal-packing forces. Our results suggest that, in the absence of a disulfide bridge, most BJP CLs are probably mobile in solution. This may explain their high susceptibility to proteases and the absence of naturally occurring crystals for these dimers. Furthermore, these findings of an unusual quaternary structure of an immunoglobulin light-chain association extend our knowledge about the large and highly diverse structures of the immunoglobulin superfamily.  (+info)

Antitumor activity of thalidomide in refractory multiple myeloma. (2/179)

BACKGROUND: Patients with myeloma who relapse after high-dose chemotherapy have few therapeutic options. Since increased bone marrow vascularity imparts a poor prognosis in myeloma, we evaluated the efficacy of thalidomide, which has antiangiogenic properties, in patients with refractory disease. METHODS: Eighty-four previously treated patients with refractory myeloma (76 with a relapse after high-dose chemotherapy) received oral thalidomide as a single agent for a median of 80 days (range, 2 to 465). The starting dose was 200 mg daily, and the dose was increased by 200 mg every two weeks until it reached 800 mg per day. Response was assessed on the basis of a reduction of the myeloma protein in serum or Bence Jones protein in urine that lasted for at least six weeks. RESULTS: The serum or urine levels of paraprotein were reduced by at least 90 percent in eight patients (two had a complete remission), at least 75 percent in six patients, at least 50 percent in seven patients, and at least 25 percent in six patients, for a total rate of response of 32 percent. Reductions in the paraprotein levels were apparent within two months in 78 percent of the patients with a response and were associated with decreased numbers of plasma cells in bone marrow and increased hemoglobin levels. The microvascular density of bone marrow did not change significantly in patients with a response. At least one third of the patients had mild or moderate constipation, weakness or fatigue, or somnolence. More severe adverse effects were infrequent (occurring in less than 10 percent of patients), and hematologic effects were rare. As of the most recent follow-up, 36 patients had died (30 with no response and 6 with a response). After 12 months of follow-up, Kaplan-Meier estimates of the mean (+/-SE) rates of event-free survival and overall survival for all patients were 22+/-5 percent and 58+/-5 percent, respectively. CONCLUSIONS: Thalidomide is active against advanced myeloma. It can induce marked and durable responses in some patients with multiple myeloma, including those who relapse after high-dose chemotherapy.  (+info)

Structural relationship of kappa-type light chains with AL amyloidosis: multiple deletions found in a VkappaIV protein. (3/179)

Two amyloidogenic Bence Jones proteins (Am37 VkappaIV and NIG1 VkappaI) and one non-amyloidogenic protein (NIG26 VkappaIII) were characterized. The protein Am37 had four deletions when compared with the translated germ-line gene sequence: two Ser residues following position 27 (27e, 27f) in CDR1 and two amino acids Pro-44, and Tyr-49 in FR2 were deleted. A strictly conserved salt-bridge-forming amino acid, Asp-82, was replaced by the hydrophobic residue Leu. In a comparative study of amyloidogenic and non-amyloidogenic proteins, five amino acids (Ser-10, Ala-13, Ser-65, Gln-90, and Ile-106) were found to be unique to NIG1 and several other amyloidogenic proteins. Additional substitutions also occur within these proteins. These substitutions might be significant in altering protein folding as well as in contributing to their aggregation as amyloid fibrils.  (+info)

Some Bence-Jones proteins enter cultured renal tubular cells, reach nuclei and induce cell death. (4/179)

Eighteen monoclonal Bence-Jones proteins (BJPs) were examined for their effects on cultured LLC-PK1 (porcine kidney proximal tubule) cells as well as for their amidase and DNase activities. Five proteins were found to enter the cell and to gain access to the nucleus without degradation of epitopes. Intranuclear BJPs ultimately induced DNA fragmentation and cell death. BJPs with relatively high amidase activity were cytotoxic. On the other hand, three of four BJPs with DNase activity had a cytocidal effect on cultured cells; the remaining BJP, which had a relatively high DNase activity but a very low amidase activity, failed to enter the cell and was not cytotoxic in vitro. These results suggest that catalytic and cytotoxic activities of some BJPs may make a significant contribution, in a substantial proportion of myeloma patients, to the development and/or deterioration of the disease.  (+info)

Thermodynamic modulation of light chain amyloid fibril formation. (5/179)

To obtain further insight into the pathogenesis of amyloidosis and develop therapeutic strategies to inhibit fibril formation we investigated: 1) the relationship between intrinsic physical properties (thermodynamic stability and hydrogen-deuterium (H-D) exchange rates) and the propensity of human immunoglobulin light chains to form amyloid fibrils in vitro; and 2) the effects of extrinsically modulating these properties on fibril formation. An amyloid-associated protein readily formed amyloid fibrils in vitro and had a lower free energy of unfolding than a homologous nonpathological protein, which did not form fibrils in vitro. H-D exchange was much faster for the pathological protein, suggesting it had a greater fraction of partially folded molecules. The thermodynamic stabilizer sucrose completely inhibited fibril formation by the pathological protein and shifted the values for its physical parameters to those measured for the nonpathological protein in buffer alone. Conversely, urea sufficiently destabilized the nonpathological protein such that its measured physical properties were equivalent to those of the pathological protein in buffer, and it formed fibrils. Thus, fibril formation by light chains is predominantly controlled by thermodynamic stability; and a rational strategy to inhibit amyloidosis is to design high affinity ligands that specifically increase the stability of the native protein.  (+info)

Extramedullary plasmacytoma in a horse with ptyalism and dysphagia. (6/179)

A Clydesdale mare was examined for weight loss, inappetence, ptyalism, and dysphagia. The main abnormality revealed by serum biochemistry was a marked hyperglobulinemia, and protein electrophoresis revealed a monoclonal gammopathy in the gamma region. The urine was positive for Bence Jones proteins. These findings suggested a plasma cell tumor. The neoplasm could not be located with extensive antemortem examination. At postmortem, neoplastic cells morphologically compatible with plasma cells and positive for equine IgG with imunoperoxidase staining infiltrated the pericardium, mediastinal stromal tissues, adrenal glands, meninges, atrioventricular valves, aorta, abdominal and thoracic fat, and nerves, including the trigeminal nerve. The neoplastic cells invading the cranial nerves were responsible for many of the presenting signs.  (+info)

A surgical case of solitary plasmacytoma of rib origin with biclonal gammopathy. (7/179)

Localized solitary plasmacytoma of the bone (SPB) is a rare disease and is characterized by only one or two isolated bone lesions with no evidence of disease dissemination. A previously healthy 44-year-old male was admitted for evaluation of an abnormal radiographic shadow in the left middle lung field with symptoms of left back pain. Radiological evaluation revealed a peripheral opacity in the left chest wall, which was highly suspected to be a chest wall tumor. CT-guided transcutaneous needle biopsy of the tumor was performed and the specimens showed a monomorphous population of mature plasma cells. The bone marrow biopsy findings revealed no evidence of myeloma and bone scanning revealed only abnormal accumulation in the left seventh rib. He had mild M-proteins in a urine sample and Bence-Jones protein was detected. Immunoelectrophoresis revealed mild biclonal gammopathy of Bence-Jones protein of both the kappa and lambda light-chain types. Under a diagnosis of solitary bone plasmacytoma, preoperative radiation therapy with doses of 40 Gy for the tumor was performed. He underwent complete en bloc resection of the chest wall, including one-third of the left sixth and seventh ribs, the intercostal muscle and the parietal pleura. The protein abnormalities in the urine sample disappeared following surgical resection. Adjuvant chemotherapy using melphalan and prednisolone was performed. He is doing well without evidence of tumor recurrence 2 years following his initial diagnosis.  (+info)

A case of gamma 3 heavy chain disease with vacuolated plasma cells: a clinical, immunological, and ultrastructural study. (8/179)

A patient with lambda Bence-Jones proteinuria, Waldenstrom's macroglobulinaemia, and Franklin's disease (gamma HCD), but without clinical evidence of a lymphoproliferative disorder, is presented. The serum contained two distinct immunoglobulin abnormalities: a monoclonal immunoglobulin M (IgM) of lambda type, and a protein fragment which was immunologically related to immunoglobulin G (IgG) and devoid of light chain activity. This gamma HCD protein belongs to the gamma 3 subclass with a molecular weight of approximately 60,000 daltons. The urine contained a Bence-Jones lambda protein as well as the gamma HCD fragment. The two paraproteins were probably secreted by two different malignant clones. Ultrastructural study revealed pathological vacuolated plasma cells of a sort that has hitherto been principally described in association with micron HCD. The mechanism of the intracellular storage of pathological immunoglobulins is discussed in the light of the ultrastructural study.  (+info)

Bence Jones protein is a type of immunoglobulin light chain that can be detected in the urine or blood of some patients with certain diseases, most notably multiple myeloma. It's named after Henry Bence Jones, a 19th-century English physician who first described it.

These proteins are produced by malignant plasma cells, which are a type of white blood cell found in the bone marrow. In multiple myeloma, these cancerous cells multiply and produce abnormal amounts of immunoglobulins, leading to the overproduction of Bence Jones proteins.

When these proteins are excreted in the urine, they can cause damage to the kidneys, leading to kidney dysfunction or failure. Therefore, the detection of Bence Jones protein in the urine can be a sign of multiple myeloma or other related diseases. However, it's important to note that not all patients with multiple myeloma will have Bence Jones proteins in their urine.

Multiple myeloma is a type of cancer that forms in a type of white blood cell called a plasma cell. Plasma cells help your body fight infection by producing antibodies. In multiple myeloma, cancerous plasma cells accumulate in the bone marrow and crowd out healthy blood cells. Rather than producing useful antibodies, the cancer cells produce abnormal proteins that can cause complications such as kidney damage, bone pain and fractures.

Multiple myeloma is a type of cancer called a plasma cell neoplasm. Plasma cell neoplasms are diseases in which there is an overproduction of a single clone of plasma cells. In multiple myeloma, this results in the crowding out of normal plasma cells, red and white blood cells and platelets, leading to many of the complications associated with the disease.

The abnormal proteins produced by the cancer cells can also cause damage to organs and tissues in the body. These abnormal proteins can be detected in the blood or urine and are often used to monitor the progression of multiple myeloma.

Multiple myeloma is a relatively uncommon cancer, but it is the second most common blood cancer after non-Hodgkin lymphoma. It typically occurs in people over the age of 65, and men are more likely to develop multiple myeloma than women. While there is no cure for multiple myeloma, treatments such as chemotherapy, radiation therapy, and stem cell transplantation can help manage the disease and its symptoms, and improve quality of life.

Gamma-globulins are a type of protein found in the blood serum, specifically a class of immunoglobulins (antibodies) known as IgG. They are the most abundant type of antibody and provide long-term defense against bacterial and viral infections. Gamma-globulins can also be referred to as "gamma globulin" or "gamma immune globulins."

These proteins are produced by B cells, a type of white blood cell, in response to an antigen (a foreign substance that triggers an immune response). IgG gamma-globulins have the ability to cross the placenta and provide passive immunity to the fetus. They can be measured through various medical tests such as serum protein electrophoresis (SPEP) or immunoelectrophoresis, which are used to diagnose and monitor conditions related to immune system disorders, such as multiple myeloma or primary immunodeficiency diseases.

In addition, gamma-globulins can be administered therapeutically in the form of intravenous immunoglobulin (IVIG) to provide passive immunity for patients with immunodeficiencies, autoimmune disorders, or infectious diseases.

Immunoglobulin lambda-chains (Igλ) are one type of light chain found in the immunoglobulins, also known as antibodies. Antibodies are proteins that play a crucial role in the immune system's response to foreign substances, such as bacteria and viruses.

Immunoglobulins are composed of two heavy chains and two light chains, which are interconnected by disulfide bonds. There are two types of light chains: kappa (κ) and lambda (λ). Igλ chains are one type of light chain that can be found in association with heavy chains to form functional antibodies.

Igλ chains contain a variable region, which is responsible for recognizing and binding to specific antigens, and a constant region, which determines the class of the immunoglobulin (e.g., IgA, IgD, IgE, IgG, or IgM).

In humans, approximately 60% of all antibodies contain Igλ chains, while the remaining 40% contain Igκ chains. The ratio of Igλ to Igκ chains can vary depending on the type of immunoglobulin and its function in the immune response.

Myeloma proteins, also known as monoclonal immunoglobulins or M-proteins, are entire or abnormal immunoglobulin (antibody) molecules produced by a single clone of plasma cells, which are malignant in the case of multiple myeloma and some related disorders. These proteins accumulate in the blood and/or urine and can cause damage to various organs and tissues.

In multiple myeloma, the excessive proliferation of these plasma cells leads to the overproduction of a single type of immunoglobulin or its fragments, which can be detected and quantified in serum and/or urine electrophoresis. The most common types of myeloma proteins are IgG and IgA, followed by light chains (Bence Jones proteins) and, less frequently, IgD and IgM.

The presence and levels of myeloma proteins are important diagnostic markers for multiple myeloma and related disorders, such as monoclonal gammopathy of undetermined significance (MGUS) and Waldenström macroglobulinemia. Regular monitoring of these proteins helps assess the disease's activity, response to treatment, and potential complications like kidney dysfunction or amyloidosis.

Immunoglobulin light chains are the smaller protein subunits of an immunoglobulin, also known as an antibody. They are composed of two polypeptide chains, called kappa (κ) and lambda (λ), which are produced by B cells during the immune response. Each immunoglobulin molecule contains either two kappa or two lambda light chains, in association with two heavy chains.

Light chains play a crucial role in the antigen-binding site of an antibody, where they contribute to the specificity and affinity of the interaction between the antibody and its target antigen. In addition to their role in immune function, abnormal production or accumulation of light chains can lead to various diseases, such as multiple myeloma and amyloidosis.

Amyloidosis is a medical condition characterized by the abnormal accumulation of insoluble proteins called amyloid in various tissues and organs throughout the body. These misfolded protein deposits can disrupt the normal function of affected organs, leading to a range of symptoms depending on the location and extent of the amyloid deposition.

There are different types of amyloidosis, classified based on the specific proteins involved:

1. Primary (AL) Amyloidosis: This is the most common form, accounting for around 80% of cases. It results from the overproduction and misfolding of immunoglobulin light chains, typically by clonal plasma cells in the bone marrow. The amyloid deposits can affect various organs, including the heart, kidneys, liver, and nervous system.
2. Secondary (AA) Amyloidosis: This form is associated with chronic inflammatory diseases, such as rheumatoid arthritis, tuberculosis, or familial Mediterranean fever. The amyloid fibrils are composed of serum amyloid A protein (SAA), an acute-phase reactant produced during the inflammatory response. The kidneys are commonly affected in this type of amyloidosis.
3. Hereditary or Familial Amyloidosis: These forms are caused by genetic mutations that result in the production of abnormal proteins prone to misfolding and amyloid formation. Examples include transthyretin (TTR) amyloidosis, fibrinogen amyloidosis, and apolipoprotein AI amyloidosis. These forms can affect various organs, including the heart, nerves, and kidneys.
4. Dialysis-Related Amyloidosis: This form is seen in patients undergoing long-term dialysis for chronic kidney disease. The amyloid fibrils are composed of beta-2 microglobulin, a protein that accumulates due to impaired clearance during dialysis. The joints and bones are commonly affected in this type of amyloidosis.

The diagnosis of amyloidosis typically involves a combination of clinical evaluation, imaging studies, and tissue biopsy with the demonstration of amyloid deposition using special stains (e.g., Congo red). Treatment depends on the specific type and extent of organ involvement and may include supportive care, medications to target the underlying cause (e.g., chemotherapy, immunomodulatory agents), and organ transplantation in some cases.

Immunoglobulin kappa-chains are one of the two types of light chains (the other being lambda-chains) that make up an immunoglobulin molecule, also known as an antibody. These light chains combine with heavy chains to form the antigen-binding site of an antibody, which is responsible for recognizing and binding to specific antigens or foreign substances in the body.

Kappa-chains contain a variable region that differs between different antibodies and contributes to the diversity of the immune system's response to various antigens. They also have a constant region, which is consistent across all kappa-chains. Approximately 60% of all human antibodies contain kappa-chains, while the remaining 40% contain lambda-chains. The relative proportions of kappa and lambda chains can be used in diagnostic tests to identify clonal expansions of B cells, which may indicate a malignancy such as multiple myeloma or lymphoma.

Immunoelectrophoresis (IEP) is a laboratory technique used in the field of clinical pathology and immunology. It is a method for separating and identifying proteins, particularly immunoglobulins or antibodies, in a sample. This technique combines the principles of electrophoresis, which separates proteins based on their electric charge and size, with immunological reactions, which detect specific proteins using antigen-antibody interactions.

In IEP, a protein sample is first separated by electrophoresis in an agarose or agar gel matrix on a glass slide or in a test tube. After separation, an antibody specific to the protein of interest is layered on top of the gel and allowed to diffuse towards the separated proteins. This creates a reaction between the antigen (protein) and the antibody, forming a visible precipitate at the point where they meet. The precipitate line's position and intensity can then be analyzed to identify and quantify the protein of interest.

Immunoelectrophoresis is particularly useful in diagnosing various medical conditions, such as immunodeficiency disorders, monoclonal gammopathies (like multiple myeloma), and other plasma cell dyscrasias. It can help detect abnormal protein patterns, quantify specific immunoglobulins, and identify the presence of M-proteins or Bence Jones proteins, which are indicative of monoclonal gammopathies.

Serum globulins are a group of proteins present in the liquid portion of blood, known as serum. They are produced by the immune system in response to foreign substances such as bacteria, viruses, and allergens. Serum globulins include several types of immunoglobulins (antibodies), complement components, and other proteins involved in the immune response.

The serum globulin level is often measured as part of a complete blood count (CBC) or a protein electrophoresis test. An elevated serum globulin level may indicate an ongoing infection, inflammation, or an autoimmune disorder. Conversely, a decreased level may suggest a liver or kidney disease, or a malnutrition condition. It is important to note that the interpretation of serum globulin levels should be done in conjunction with other laboratory and clinical findings.

Electrophoresis is a laboratory technique used in the field of molecular biology and chemistry to separate charged particles, such as DNA, RNA, or proteins, based on their size and charge. This technique uses an electric field to drive the movement of these charged particles through a medium, such as gel or liquid.

In electrophoresis, the sample containing the particles to be separated is placed in a matrix, such as a gel or a capillary tube, and an electric current is applied. The particles in the sample have a net charge, either positive or negative, which causes them to move through the matrix towards the oppositely charged electrode.

The rate at which the particles move through the matrix depends on their size and charge. Larger particles move more slowly than smaller ones, and particles with a higher charge-to-mass ratio move faster than those with a lower charge-to-mass ratio. By comparing the distance that each particle travels in the matrix, researchers can identify and quantify the different components of a mixture.

Electrophoresis has many applications in molecular biology and medicine, including DNA sequencing, genetic fingerprinting, protein analysis, and diagnosis of genetic disorders.

Electrophoresis, starch gel is a type of electrophoretic technique used in laboratory settings for the separation and analysis of large biomolecules such as DNA, RNA, and proteins. In this method, a gel made from cooked starch is used as the supporting matrix for the molecules being separated.

The sample containing the mixture of biomolecules is loaded onto the gel and an electric field is applied, causing the negatively charged molecules to migrate towards the positive electrode. The starch gel acts as a molecular sieve, with smaller molecules moving more quickly through the gel than larger ones. This results in the separation of the mixture into individual components based on their size and charge.

Once the separation is complete, the gel can be stained to visualize the separated bands. Different staining techniques are used depending on the type of biomolecule being analyzed. For example, proteins can be stained with dyes such as Coomassie Brilliant Blue or silver nitrate, while nucleic acids can be stained with dyes such as ethidium bromide.

Starch gel electrophoresis is a relatively simple and inexpensive technique that has been widely used in molecular biology research and diagnostic applications. However, it has largely been replaced by other electrophoretic techniques, such as polyacrylamide gel electrophoresis (PAGE), which offer higher resolution and can be automated for high-throughput analysis.

Waldenstrom macroglobulinemia is a type of rare cancer called a lymphoplasmacytic lymphoma. It is characterized by the uncontrolled growth of malignant white blood cells, specifically B lymphocytes or plasma cells, in the bone marrow and sometimes in other organs. These abnormal cells produce an excessive amount of a protein called macroglobulin, which can lead to the thickening of the blood and various symptoms associated with this condition.

The signs and symptoms of Waldenstrom macroglobulinemia may include fatigue, weakness, bruising or bleeding, frequent infections, numbness or tingling in the hands and feet, visual disturbances, and confusion or difficulty thinking. The diagnosis typically involves a combination of blood tests, bone marrow biopsy, imaging studies, and sometimes genetic testing to confirm the presence of the disease and determine its extent.

Treatment options for Waldenstrom macroglobulinemia depend on the severity of the symptoms and the stage of the disease. They may include chemotherapy, targeted therapy, immunotherapy, stem cell transplantation, or a combination of these approaches. Regular follow-up care is essential to monitor the progression of the disease and adjust treatment plans as needed.

Paraproteinemias refer to the presence of abnormal levels of paraproteins in the blood. Paraproteins are immunoglobulins (antibodies) produced by plasma cells, which are a type of white blood cell found in the bone marrow. In healthy individuals, paraproteins play a role in the immune system's response to infection and disease. However, in certain conditions, such as multiple myeloma, monoclonal gammopathy of undetermined significance (MGUS), and Waldenstrom macroglobulinemia, plasma cells produce excessive amounts of a single type of paraprotein, leading to its accumulation in the blood.

Paraproteinemias can cause various symptoms depending on the level of paraproteins present and their impact on organs and tissues. These symptoms may include fatigue, weakness, numbness or tingling in the extremities, bone pain, recurrent infections, and kidney problems. In some cases, paraproteinemias may not cause any symptoms and may only be detected during routine blood tests.

It is important to note that while paraproteinemias are often associated with plasma cell disorders, they can also occur in other conditions such as chronic inflammation or autoimmune diseases. Therefore, further testing and evaluation are necessary to determine the underlying cause of paraproteinemia and develop an appropriate treatment plan.

Immunoglobulin fragments refer to the smaller protein units that are formed by the digestion or break-down of an intact immunoglobulin, also known as an antibody. Immunoglobulins are large Y-shaped proteins produced by the immune system to identify and neutralize foreign substances such as pathogens or toxins. They consist of two heavy chains and two light chains, held together by disulfide bonds.

The digestion or break-down of an immunoglobulin can occur through enzymatic cleavage, which results in the formation of distinct fragments. The most common immunoglobulin fragments are:

1. Fab (Fragment, antigen binding) fragments: These are formed by the digestion of an intact immunoglobulin using the enzyme papain. Each Fab fragment contains a single antigen-binding site, consisting of a portion of one heavy chain and one light chain. The Fab fragments retain their ability to bind to specific antigens.
2. Fc (Fragment, crystallizable) fragments: These are formed by the digestion of an intact immunoglobulin using the enzyme pepsin or through the natural breakdown process in the body. The Fc fragment contains the constant region of both heavy chains and is responsible for effector functions such as complement activation, binding to Fc receptors on immune cells, and antibody-dependent cellular cytotoxicity (ADCC).

These immunoglobulin fragments play crucial roles in various immune responses and diagnostic applications. For example, Fab fragments can be used in immunoassays for the detection of specific antigens, while Fc fragments can mediate effector functions that help eliminate pathogens or damaged cells from the body.

Proteinuria is a medical term that refers to the presence of excess proteins, particularly albumin, in the urine. Under normal circumstances, only small amounts of proteins should be found in the urine because the majority of proteins are too large to pass through the glomeruli, which are the filtering units of the kidneys.

However, when the glomeruli become damaged or diseased, they may allow larger molecules such as proteins to leak into the urine. Persistent proteinuria is often a sign of kidney disease and can indicate damage to the glomeruli. It is usually detected through a routine urinalysis and may be confirmed with further testing.

The severity of proteinuria can vary, and it can be a symptom of various underlying conditions such as diabetes, hypertension, glomerulonephritis, and other kidney diseases. Treatment for proteinuria depends on the underlying cause and may include medications to control blood pressure, manage diabetes, or reduce protein loss in the urine.

Carmustine is a chemotherapy drug used to treat various types of cancer, including brain tumors, multiple myeloma, and Hodgkin's lymphoma. It belongs to a class of drugs called alkylating agents, which work by damaging the DNA in cancer cells, preventing them from dividing and growing.

Carmustine is available as an injectable solution that is administered intravenously (into a vein) or as implantable wafers that are placed directly into the brain during surgery. The drug can cause side effects such as nausea, vomiting, hair loss, and low blood cell counts, among others. It may also increase the risk of certain infections and bleeding complications.

As with all chemotherapy drugs, carmustine can have serious and potentially life-threatening side effects, and it should only be administered under the close supervision of a qualified healthcare professional. Patients receiving carmustine treatment should be closely monitored for signs of toxicity and other adverse reactions.

Immunodiffusion is a laboratory technique used in immunology to detect and measure the presence of specific antibodies or antigens in a sample. It is based on the principle of diffusion, where molecules move from an area of high concentration to an area of low concentration until they reach equilibrium. In this technique, a sample containing an unknown quantity of antigen or antibody is placed in a gel or agar medium that contains a known quantity of antibody or antigen, respectively.

The two substances then diffuse towards each other and form a visible precipitate at the point where they meet and reach equivalence, which indicates the presence and quantity of the specific antigen or antibody in the sample. There are several types of immunodiffusion techniques, including radial immunodiffusion (RID) and double immunodiffusion (Ouchterlony technique). These techniques are widely used in diagnostic laboratories to identify and measure various antigens and antibodies, such as those found in infectious diseases, autoimmune disorders, and allergic reactions.

Melphalan is an antineoplastic agent, specifically an alkylating agent. It is used in the treatment of multiple myeloma and other types of cancer. The medical definition of Melphalan is:

A nitrogen mustard derivative that is used as an alkylating agent in the treatment of cancer, particularly multiple myeloma and ovarian cancer. Melphalan works by forming covalent bonds with DNA, resulting in cross-linking of the double helix and inhibition of DNA replication and transcription. This ultimately leads to cell cycle arrest and apoptosis (programmed cell death) in rapidly dividing cells, such as cancer cells.

Melphalan is administered orally or intravenously, and its use is often accompanied by other anticancer therapies, such as radiation therapy or chemotherapy. Common side effects of Melphalan include nausea, vomiting, diarrhea, and bone marrow suppression, which can lead to anemia, neutropenia, and thrombocytopenia. Other potential side effects include hair loss, mucositis, and secondary malignancies.

It is important to note that Melphalan should be used under the close supervision of a healthcare professional, as it can cause serious adverse reactions if not administered correctly.

Iodine isotopes are different forms of the chemical element iodine, which have different numbers of neutrons in their nuclei. Iodine has a total of 53 protons in its nucleus, and its stable isotope, iodine-127, has 74 neutrons, giving it a mass number of 127. However, there are also radioactive isotopes of iodine, which have different numbers of neutrons and are therefore unstable.

Radioactive isotopes of iodine emit radiation as they decay towards a stable state. For example, iodine-131 is a commonly used isotope in medical imaging and therapy, with a half-life of about 8 days. It decays by emitting beta particles and gamma rays, making it useful for treating thyroid cancer and other conditions that involve overactive thyroid glands.

Other radioactive iodine isotopes include iodine-123, which has a half-life of about 13 hours and is used in medical imaging, and iodine-125, which has a half-life of about 60 days and is used in brachytherapy (a type of radiation therapy that involves placing radioactive sources directly into or near tumors).

It's important to note that exposure to radioactive iodine isotopes can be harmful, especially if it occurs through inhalation or ingestion. This is because the iodine can accumulate in the thyroid gland and cause damage over time. Therefore, appropriate safety measures must be taken when handling or working with radioactive iodine isotopes.

Sulfhydryl compounds, also known as thiol compounds, are organic compounds that contain a functional group consisting of a sulfur atom bonded to a hydrogen atom (-SH). This functional group is also called a sulfhydryl group. Sulfhydryl compounds can be found in various biological systems and play important roles in maintaining the structure and function of proteins, enzymes, and other biomolecules. They can also act as antioxidants and help protect cells from damage caused by reactive oxygen species. Examples of sulfhydryl compounds include cysteine, glutathione, and coenzyme A.

Gel chromatography is a type of liquid chromatography that separates molecules based on their size or molecular weight. It uses a stationary phase that consists of a gel matrix made up of cross-linked polymers, such as dextran, agarose, or polyacrylamide. The gel matrix contains pores of various sizes, which allow smaller molecules to penetrate deeper into the matrix while larger molecules are excluded.

In gel chromatography, a mixture of molecules is loaded onto the top of the gel column and eluted with a solvent that moves down the column by gravity or pressure. As the sample components move down the column, they interact with the gel matrix and get separated based on their size. Smaller molecules can enter the pores of the gel and take longer to elute, while larger molecules are excluded from the pores and elute more quickly.

Gel chromatography is commonly used to separate and purify proteins, nucleic acids, and other biomolecules based on their size and molecular weight. It is also used in the analysis of polymers, colloids, and other materials with a wide range of applications in chemistry, biology, and medicine.

Hemagglutination is a medical term that refers to the agglutination or clumping together of red blood cells (RBCs) in the presence of an agglutinin, which is typically a protein or a polysaccharide found on the surface of certain viruses, bacteria, or incompatible blood types.

In simpler terms, hemagglutination occurs when the agglutinin binds to specific antigens on the surface of RBCs, causing them to clump together and form visible clumps or aggregates. This reaction is often used in diagnostic tests to identify the presence of certain viruses or bacteria, such as influenza or HIV, by mixing a sample of blood or other bodily fluid with a known agglutinin and observing whether hemagglutination occurs.

Hemagglutination inhibition (HI) assays are also commonly used to measure the titer or concentration of antibodies in a serum sample, by adding serial dilutions of the serum to a fixed amount of agglutinin and observing the highest dilution that still prevents hemagglutination. This can help determine whether a person has been previously exposed to a particular pathogen and has developed immunity to it.

Prednisone is a synthetic glucocorticoid, which is a type of corticosteroid hormone. It is primarily used to reduce inflammation in various conditions such as asthma, allergies, arthritis, and autoimmune disorders. Prednisone works by mimicking the effects of natural hormones produced by the adrenal glands, suppressing the immune system's response and reducing the release of substances that cause inflammation.

It is available in oral tablet form and is typically prescribed to be taken at specific times during the day, depending on the condition being treated. Common side effects of prednisone include increased appetite, weight gain, mood changes, insomnia, and easy bruising. Long-term use or high doses can lead to more serious side effects such as osteoporosis, diabetes, cataracts, and increased susceptibility to infections.

Healthcare providers closely monitor patients taking prednisone for extended periods to minimize the risk of adverse effects. It is essential to follow the prescribed dosage regimen and not discontinue the medication abruptly without medical supervision, as this can lead to withdrawal symptoms or a rebound of the underlying condition.

Disulfides are a type of organic compound that contains a sulfur-sulfur bond. In the context of biochemistry and medicine, disulfide bonds are often found in proteins, where they play a crucial role in maintaining their three-dimensional structure and function. These bonds form when two sulfhydryl groups (-SH) on cysteine residues within a protein molecule react with each other, releasing a molecule of water and creating a disulfide bond (-S-S-) between the two cysteines. Disulfide bonds can be reduced back to sulfhydryl groups by various reducing agents, which is an important process in many biological reactions. The formation and reduction of disulfide bonds are critical for the proper folding, stability, and activity of many proteins, including those involved in various physiological processes and diseases.
