"Hemiarthroplasties" Natural Recordings by Native Speakers
Hemiarthroplasties is a medical term that refers to a surgical procedure where only one joint is replaced with an artificial joint, usually a partial replacement of a hip or knee joint. In this procedure, the damaged or arthritic portion of the joint is removed and replaced with a prosthetic implant, leaving the surrounding bone and soft tissue intact. The goal of hemiarthroplasties is to relieve pain, improve mobility, and restore function in the joint.
Hemerythrin is a copper-free oxygen-binding protein found in the hemolymph (fluid that circulates throughout the body) of some marine animals, including mollusks and arthropods. It is a variant of hemocyanin, which is a protein that binds oxygen in the presence of copper ions. Hemerythrin functions similarly to hemocyanin, but it has a different biocoordination chemistry and is not dependent on copper ions for its oxygen-binding properties.
A hemiacetal is a type of organic compound that is formed when an alcohol reacts with an aldehyde or a ketone in the presence of acid. It is a half-ester of the original aldehyde or ketone and an alcohol. Hemiacetals are important in the formation of many natural products, such as starches, cellulose, and other biopolymers. They can also be used as intermediate compounds in the synthesis of other organic compounds.
Hemianaesthesia is a neurological term that refers to a condition where there is reduced or absent sensation on one half of the body, often due to damage to the nerves or brain. The sensation impairment can include numbness, tingling, or loss of sensation on one side of the body, including the face, arm, or leg.
Hemianesthesia is a medical term that refers to a type of nerve damage or dysfunction that results in a decrease or loss of sensation on one side of the body. This sensation can be in the form of numbness, tingling, weakness, or loss of proprioception (the sense of body position and movement). In hemianesthesia, the affected side of the body may feel as if it is anesthetized or numb, hence the name. It is often the result of damage to the spinal cord, brain, or peripheral nerves.
Hemianopia is a type of visual field defect that occurs when a person loses the ability to see part or all of one half of their visual field due to damage to the visual processing areas in the brain. It can result from a variety of causes, including stroke, traumatic brain injury, tumors, or inflammatory diseases such as multiple sclerosis. Hemianopia can be partial, causing only a small deficiency in vision, or it can be complete, causing a complete loss of vision in one half of the visual field.
Hemianopic refers to a type of visual field defect that affects one half of the visual field in each eye.
Hemianopsia is a type of visual field defect in which a person's peripheral vision is reduced or absent on one side of their visual field. It can be thought of as "looking through a tunnel" with a blind spot on one side. Hemianopsia can be caused by a variety of factors, including stroke, brain tumor, head injury, or other neurological disorders.
Hemiaplasia is a medical term that refers to the condition where there is an absolute absence or underdevelopment of half of a limb or digit. It is a type of congenital anomaly, meaning it is present at birth. In individuals with hemiaplasia, the affected limb is typically smaller than the normal counterpart and may be absence of certain muscles, bones, or other structures. This condition can occur on either the upper or lower extremities, and the severity of the condition can vary widely from individual to individual.
Hemiarthroplasty is a type of surgical procedure where only one side of the joint is replaced with an artificial prosthesis, typically to relieve pressure and alleviate pain in the affected area. It is often used to treat osteoarthritis, particularly in the hip or shoulder, when the joint is worn out but other structures such as muscles, tendons, and ligaments are still intact.
Hemiascomycetes is a class of fungi in the subphylum Pezizomycotina. It includes yeasts, which are single-celled fungi that can reproduce by budding or fission. The term "Hemiascomycetes" comes from the Greek words "hemi" meaning "half" and "skomos" meaning "ashen", referring to the typically ashy appearance of the fruiting bodies of some members of this group.
Hemiasomatognosia is a rare neurological disorder characterized by a lack of awareness or recognition of certain parts of one's own body. The affected individual may have difficulty identifying the affected limb or side of the body, and may even deny that it belongs to them. It is often associated with other cognitive and sensory impairments, and is usually caused by damage to the brain's parietal lobe or other areas involved in body awareness.
Hemibalism is a rare neurological disorder characterized by a tendency to favor one side of the body, but not as extreme as hemiparesis (weakness on one side) or hemiplegia (paralysis on one side). People with hemibalism may exhibit involuntary movements, incoordination, and difficulties with balance and spatial awareness.
Hemiballism is a rare neurological disorder characterized by abnormal involuntary movements, specifically tremors and chorea (involuntary jerky movements), predominantly affecting one side of the body. The term "hemiballism" literally means "half-ballism", with "hemi-" referring to half and "ballism" referring to the sudden, jerky movements of the affected limbs.
Hemiballismus is a rare and severe neurological disorder characterized by involuntary, swinging movements of the arm on one side of the body. It is typically caused by a lesion or damage to the subthalamic nucleus, a region deep in the brain that is involved in motor control. The movements are often dramatic and can be quite distressing for those who experience them.
Hemiblock is an irregular heart rhythm characterized by a blockage of electrical signals in the heart, typically occurring in the right bundle branch. It impairs the heart's ability to pump blood efficiently, often causing symptoms such as rapid or irregular heartbeat, shortness of breath, fatigue, and dizziness.
Hemicardia refers to a type of abnormal cardiac rhythm, specifically a type of atrial tachycardia that originates from the atrial muscle itself, rather than from the atrioventricular (AV) node. It is usually characterized by a rapid heart rate, often above 140 beats per minute, and can be associated with symptoms such as palpitations, shortness of breath, and lightheadedness. Hemicardia can be treated with medications, cardioversion, or other procedures depending on its underlying cause and severity.
