Nijmegen
Nijmegen ( , ; Nijmeegs: ) is the largest city in the Dutch province of Gelderland and the ninth largest of the Netherlands as a whole. Located on the Waal River close to the German border, Nijmegen is one of the oldest cities in the Netherlands and the first to be recognized as such in Roman times. In 2005, it celebrated 2,000 years of existence. Nijmegen became a free imperial city in 1230 and in 1402 a Hanseatic city. Since 1923 it has been a university city with the opening of a Catholic institution now known as the Radboud University Nijmegen. The city is well known for the annual International Four Days Marches Nijmegen event. Its population as of 2024 was 187,011. Population centres The municipality is formed by the city of Nijmegen, incorporating the former villages of Hatert, Hees and Neerbosch, as well as the urban expansion projects in Veur-Lent, Nijmegen-Oosterhout and Nijmegen–Ressen, all situated north of the river Waal. Proximity of border ...

Statin
Statins (or HMG-CoA reductase inhibitors) are a class of medications that lower cholesterol. They are prescribed typically to people who are at high risk of cardiovascular disease. Low-density lipoprotein (LDL) carriers of cholesterol play a key role in the development of atherosclerosis and coronary heart disease via the mechanisms described by the lipid hypothesis. As lipid-lowering medications, statins are effective in lowering LDL cholesterol; they are widely used for primary prevention in people at high risk of cardiovascular disease, as well as in secondary prevention for those who have developed cardiovascular disease. Side effects of statins include muscle pain, increased risk of diabetes, and abnormal blood levels of certain liver enzymes. Additionally, they have rare but severe adverse effects, particularly muscle damage, and very rarely rhabdomyolysis. They act by inhibiting the enzyme HMG-CoA reductase, which plays a central role in the production of ...

B-cell
B cells, also known as B lymphocytes, are a type of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system. B cells produce antibody molecules which may be either secreted or inserted into the plasma membrane where they serve as a part of B-cell receptors. When a naïve or memory B cell is activated by an antigen, it proliferates and differentiates into an antibody-secreting effector cell, known as a plasmablast or plasma cell. In addition, B cells present antigens (they are also classified as professional antigen-presenting cells, APCs) and secrete cytokines. In mammals B cells mature in the bone marrow, which is at the core of most bones. In birds, B cells mature in the bursa of Fabricius, a lymphoid organ where they were first discovered by Chang and Glick, which is why the ''B'' stands for ''bursa'' and not ''bone marrow'', as commonly believed. B cells, unlike the other two classes of lymphocytes, T cells and natural killer ...

Non-Hodgkin Lymphoma
Non-Hodgkin lymphoma (NHL), also known as non-Hodgkin's lymphoma, is a group of blood cancers that includes all types of lymphomas except Hodgkin lymphomas. Symptoms include enlarged lymph nodes, fever, night sweats, weight loss, and tiredness. Other symptoms may include bone pain, chest pain, or itchiness. Some forms are slow-growing while others are fast-growing. Unlike Hodgkin lymphoma, which spreads contiguously, NHL is largely a systemic illness. Signs and symptoms The signs and symptoms of non-Hodgkin lymphoma vary depending upon its location within the body. Symptoms include enlarged lymph nodes, fever, night sweats, weight loss, and tiredness. Other symptoms may include bone pain, chest pain, or itchiness. Some forms are slow growing, while others are fast growing. Enlarged lymph nodes may cause lumps to be felt under the skin when they are close to the surface of the body. Lymphomas in the skin may also result in lumps, which are commonly itchy, red, or purple. Ly ...

CD20
B-lymphocyte antigen CD20 or CD20 is B lymphocyte cell-surface molecule. It is a 33-37 kDa non-glycosylated protein. CD20 is expressed on the surface of B-cells from the pre-B phase, the expression is lost in terminally differentiated plasma cells. CD20 is used as a therapeutical target of B-cell malignancies and autoimmune diseases. Gene In humans CD20 is encoded by the ''MS4A1'' gene localized to 11q12. The gene is 16 kbp long and consists of 8 exons. There are at least 3 mRNA transcripts (resulting from alternative splicing), that are all translated into an identical full-length CD20 protein product. Variants 1 and 2 are poorly translated due to inhibitory upstream open reading frames and stem-loop structures within their 5' untranslated regions. The relative abundance of translation-competent variant 3, as opposed to the poorly translated variants 1 and 2, may be a key determinant of CD20 levels in normal and malignant human B cells and their responses to CD20-d ...

Preclinical
In drug development, preclinical development (also termed preclinical studies or nonclinical studies) is a stage of research that begins before clinical trials (testing in humans) and during which important feasibility, iterative testing and drug safety data are collected, typically in laboratory animals. The main goals of preclinical studies are to determine a starting, safe dose for first-in-human study and assess potential toxicity of the product, which typically include new medical devices, prescription drugs, and diagnostics. Companies use stylized statistics to illustrate the risks in preclinical research, such as that on average, only one in every 5,000 compounds that enters drug discovery to the stage of preclinical development becomes an approved drug. Types Each class of product may undergo different types of preclinical research. For instance, drugs may undergo pharmacodynamics (what the drug does to the body) (PD), pharmacokinetics (what the body does to th ...

Lemna
''Lemna'' is a genus of free-floating aquatic plants referred to by the common name "duckweed". They are morphologically divergent members of the arum family Araceae. These rapidly growing plants have found uses as a model system for studies in community ecology, basic plant biology, ecotoxicology, and production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture. Currently, 14 species of ''Lemna'' are recognised. Taxonomy These duckweeds were previously placed in a separate flowering plant family, the Lemnaceae, but they are now considered to be members of the Araceae. Description ''Lemna'' species grow as simple free-floating thalli on or just beneath the water surface. Most are small, not exceeding 5 mm in length, except '' Lemna trisulca'', which is elongated and has a branched structure. ''Lemna'' thalli have a single root, which distinguishes this genus from the related genera '' Wolffia'' (lacks roots), ''Spirodela'' and ''Landol ...

Biolex
Biolex Therapeutics was a biotechnology firm in the Research Triangle of North Carolina which was founded in 1997 and raised $190 million from investors. It filed for Chapter 7 bankruptcy on July 5, 2012. The company focused on expression of difficult-to-synthesize recombinant proteins in its LEX platform, which used ''Lemna'', a duckweed. The duckweeds are a family of small aquatic plants that can be grown in sterile culture. Biolex developed recombinant DNA technology for efficiently producing pharmaceutical proteins in Lemna. Therapeutic glycosylated proteins, including monoclonal antibodies and interferon (IFN-alpha2b) have been produced using the LEX platform. Biolex acquired Epicyte Pharmaceutical Inc. on May 6, 2004, and acquired the LemnaGene SA of Lyon, France in 2005. Biolex was a privately held company, originally backed by Quaker BioVentures, The Trelys Funds, and Polaris Venture Partners. The term " plantibody" is trademarked by Biolex. In May 2012 Biolex an ...

Biopharmaceutical
A biopharmaceutical, also known as a biological medical product, or biologic, is any pharmaceutical drug product manufactured in, extracted from, or semisynthesized from biological sources. Different from totally synthesized pharmaceuticals, they include vaccines, whole blood, blood components, allergenics, somatic cells, gene therapies, tissues, recombinant therapeutic protein, and living medicines used in cell therapy. Biopharmaceuticals can be composed of sugars, proteins, nucleic acids, or complex combinations of these substances, or may be living cells or tissues. They (or their precursors or components) are isolated from living sources—human, animal, plant, fungal, or microbial. They can be used in both human and animal medicine. Terminology surrounding biopharmaceuticals varies between groups and entities, with different terms referring to different subsets of therapeutics within the general biopharmaceutical category. The term biologics is often used more res ...

Fluvoxamine
Fluvoxamine, sold under the brand name Luvox among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It is primarily used to treat major depressive disorder and, perhaps more-especially, obsessive–compulsive disorder (OCD), but is also used to treat anxiety disorders such as panic disorder, social anxiety disorder, and post-traumatic stress disorder. Fluvoxamine's side-effect profile is similar to that of other SSRIs. Common adverse effects include constipation, gastrointestinal problems, headache, anxiety, irritation, sexual problems, dry mouth, sleep problems and an increased risk of suicide at the start of treatment. These effects appear to be significantly weaker than with other SSRIs, with the exception of gastrointestinal side-effects. Fluvoxamine appears to be more tolerable than other SSRIs, particularly with respect to cardiovascular complications. Compared to escitalopram and sertraline, fluvoxamine's gastrointestinal pro ...

Antidepressant
Antidepressants are a class of medications used to treat major depressive disorder, anxiety disorders, chronic pain, and addiction. Common side effects of antidepressants include Xerostomia, dry mouth, weight gain, dizziness, headaches, akathisia, sexual dysfunction, and emotional blunting. There is an increased risk of Suicidal ideation, suicidal thinking and Suicide, behavior when taken by children, adolescents, and young adults. Antidepressant discontinuation syndrome, Discontinuation syndrome, which resembles recurrent Depression (mood), depression in the case of the Selective serotonin reuptake inhibitor, SSRI class, may occur after stopping the intake of any antidepressant. Research regarding the effectiveness of antidepressants for depression in adults is controversial and has found both benefits and drawbacks. Meanwhile, evidence of benefit in children and adolescents is unclear, even though antidepressant use has considerably increased in children and adolescents in th ...
