"Rhabdovirus" Natural Recordings by Native Speakers
A virion (virus particle) with a helical nucleocapsid about 300Å in length. The surface (envelope) is acquired by budding into the plasma membrane of an infected cell. Characteristically associated with the rabies virus, and possibly with other animal viruses that cause haemorrhagic fevers.
Rhabdomyosarcomas are a type of soft tissue sarcoma, specifically a malignant tumor that arises from skeletal muscle progenitor cells. They are characterized by the presence of small, rounded cells with abnormal nuclei and a high amount of mitotic activity. Rhabdomyosarcomas can occur in any location in the body, but they most commonly present in the head and neck, extremities, and bladder/urethra. There are three subtypes of rhabdomyosarcomas:<br><br>1. Embryonal (or Embryonal Rhabdomyosarcoma): This is the most common type, accounting for about 40% of cases. It typically affects children under the age of 10 and is highly aggressive.<br>2. Alveolar (or Alveolar Rhabdomyosarcoma): This type is more common in adolescents and young adults and accounts for about 20% of cases. It tends to be more aggressive than the embryonal type.<br>3. Embryonal-alveolar (or Embryonal Alveolar Rhabdomyosarcoma): This is the least common type and often occurs in older children or young adults.<br><br>Symptoms of rhabdomyosarcoma can include:<br><br> A growing lump or tumor<br> Pain or discomfort in the affected area<br> Fatigue<br> Weight loss<br> Weakness<br> Blood in the urine or stool<br><br>Treatment for rhabdomyosarcoma typically involves a combination of surgery, chemotherapy, and radiation therapy. The prognosis and outcome depend on the type and location of the tumor, as well as the patient's overall health.
Rhabdophobia is an excessive or irrational fear of being harmed or attacked with a weapon, particularly a rod, stick, or cane. It is a specific phobia that can cause anxiety, panic, or avoidance behaviors in individuals who experience it.
Rhabdophora is a rare or obsolete word that refers to a type of framework or structure composed of rods or bars crossed at right angles.
Rhabdopleura is a genus of extinct branchiopod crustaceans that lived from the Early Devonian to the Early Carboniferous period. They are characterized by their robust, cycloidal segments and distinctive "lappings" of chitin that support the segments.
A relatively rare word!<br><br>A rhabdosome (from Greek ῥαβδός, rhabdos, rod or staff) is a type of multicellular skeleton found in some colonial organisms, particularly in certain species of colonial nematodes (roundworms), notably the genus Sabellaster and some species of hydroids (marine polyps).<br><br>In these organisms, a rhabdosome is a stiff, rod-like structure formed by the arrangement of several cells (typically, a cluster of ectodermal cells) around a central axis, providing support and protection to the organism.<br><br>In other words, a rhabdosome is a simple, rod-shaped skeletal structure made of multiple cells, found in a few specialized types of animal colonies, primarily serving a supportive function.
A rhabdosphere (also known as a fiber envelope or fiber sphere) is a theoretical concept in plant morphology that refers to the DNA and histone protein complex that forms a fiber-like structure in the nucleus of plant cells. <br><br>In plants, the rhabdosphere is a gel-like structure that is composed of a combination of histone proteins and deoxyribonucleic acid (DNA). Historically, some botanists have considered the rhabdosphere as equivalent to the nuclear envelope or the chromatin.<br><br>The term is not commonly used in contemporary cell biology and cellular genetics.
The Rhabdoviridae is a family of negative-sense single-stranded RNA viruses. They are enveloped viruses with helical symmetry, meaning that their genetic material is arranged in a spiral shape, and are typically filamentous in shape. Examples of viruses in this family include:<br><br> Rabies virus<br> Vesicular stomatitis virus<br> Ebola virus<br> Lyssavirus<br> Panchan virus<br><br>These viruses infect a wide range of hosts, including humans, animals, and birds, and can cause a variety of diseases, ranging from mild to severe.
Rhachiodont refers to a fossilized tooth of a fish of a past geological age, typically from the Jurassic period, often referring to the genus Rhachiodon, a type of extinct bony fish.
The term "rhachis" refers to the main or largest vein that runs along the midline of a leaf in plants. In botanical terms, it is the major mainstem or the longest and usually the largest rib of a compound palmate leaf, palmatisect leaves, or feather-leafed plants.
Rickets is a disorder caused by a lack of vitamin D, calcium, or phosphate. It leads to softening and weakening of the bones.<br><br>It most often affects children, particularly if they are exclusively breastfed and do not get enough vitamin D from sunlight or other sources, or if they have poor nutrition.
The word "rhacodactylus" refers to a type of lizard. Specifically, it is a genus of goannas or monitor lizards that were native to New Caledonia, an island in the Pacific Ocean east of Australia. Rhacodactylus was a name given to these lizards by British zoologist George Shaw in 1792, and it refers to the Greek words "rhachis," meaning "spine," and "dactylos," meaning "finger."
Rhacophorus is a genus of tree-frogs, commonly known as Asian tree frogs or microhylid frogs. The genus is native to Southeast Asia and parts of China. They have a distinctive large toe pads, which allow them to climb and perch on trees.
