"Acantholytic" Meaning
Acantholytic refers to a condition where the cells of the epidermis, particularly the keratinocytes, lose their ability to adhere to one another, causing the breakdown of cell-to-cell connections. This term is often used in the context of dermatology, particularly in describing certain skin disorders such as pemphigus vulgaris, where acantholysis leads to the formation of blisters.
"Acantholytic" Examples
1. The dermatologist diagnosed the patient with pemphigus vulgaris, an autoimmune disorder characterized by acantholytic blisters on the skin and mucous membranes.
2. In the histopathological examination of the biopsy, acantholytic cells were observed, indicating a disruption in the normal desmosomal junctions between keratinocytes.
3. The term acantholytic refers to the loss of cohesion among epidermal cells, which is a key feature in certain skin diseases like bullous pemphigoid.
4. Researchers found that the expression of specific adhesion molecules was reduced in acantholytic lesions, contributing to the detachment of epithelial layers.
5. Treatment for acantholytic disorders often involves immunosuppressive medications to control the immune response responsible for attacking the intercellular connections.

Acanthocytic
Acanthocytic refers to a medical or biological condition characterized by the presence of irregular, spiny, or thorny red blood cells (erythrocytes). These cells have abnormal shapes, which is called acanthocytes. This term is often used in the context of blood disorders or diseases like acanthocytosis, where a significant number of red blood cells exhibit this abnormal morphology.
Acanthocytosis
Acanthocytosis is a medical condition characterized by the presence of abnormal, spiky red blood cells called acanthocytes. These cells have irregularly protruding cytoplasmic processes, giving them a thorny appearance under a microscope. Acanthocytosis can be a symptom of various disorders, such as neurological diseases, genetic disorders, or metabolic abnormalities. It is often associated with conditions like McLeod syndrome, chorea-acanthocytosis, or abetalipoproteinemia.
Acanthodes
Acanthodes is an extinct group of fish that lived during the Paleozoic era, around 350 to 250 million years ago. They are considered to be intermediate forms between primitive jawless fish (agnathans) and more advanced jawed fish (gnathostomes). Acanthodes had scales covered with spines, which gave them a thorny appearance, hence their name derived from the Greek "akantha" meaning spine and "odes" meaning resembling.
Acanthodian
Acanthodian refers to a group of ancient fish that lived during the late Silurian to early Devonian periods, around 419 to 382 million years ago. They are characterized by having spiny scales, which gave them the name "Acanthodians," derived from the Greek word "akantha" meaning thorn or spine. These fish are considered primitive relatives of modern sharks and bony fish.
Acanthodians
Acanthodians were an extinct group of fish that lived during the Paleozoic era, around 450 to 250 million years ago. They are characterized by having spiny scales and are often referred to as "spiny sharks" or "thorn sharks." These ancient fish had a combination of shark-like and bony fish features, and they represent an important evolutionary link between these two groups.
Acanthoid
Acanthoid means resembling or having the characteristics of thorns or spines, typically referring to plants or cells with刺状或棘状的特征。
Acantholyses
Acantholyses is a medical term referring to the detachment or loss of epidermal cells, particularly those of the skin's outer layer (the stratum corneum), due to a disruption in the cohesion between them. This can result from various conditions, such as pemphigus vulgaris, a autoimmune disorder, or certain medications and irritants. It often presents as blisters or erosions on the skin.
Acantholysis
Acantholysis refers to the separation or sloughing off of the horny (cornified) layer of cells that make up the outermost part of the skin, typically seen in conditions where the normal desquamation process is disrupted. This can occur in diseases like psoriasis, pemphigus, or as a side effect of certain medications.
Acanthoma
Acanthoma is a medical term referring to a type of skin lesion or growth characterized by thickened, rough, and scaly patches. These lesions are typically benign (non-cancerous) and can occur due to various skin conditions or as a result of certain genetic factors, chronic sun exposure, or other irritations. Acanthomas may sometimes resemble actinic keratoses or basal cell carcinomas, and they are often diagnosed through visual examination and biopsy. Treatment options can include topical creams, cryotherapy, or surgical removal, depending on the case.
Acanthophis
Acanthophis is a genus of venomous snakes commonly known as antivenoms or spitting cobras. They are found in Australia, Papua New Guinea, and some nearby islands. These snakes are known for their ability to spit venom as a defense mechanism, aiming it towards the eyes of potential predators or threats.
Acanthopteri
Acanthopteri refers to a suborder of fish, commonly known as spiny-rayed fish or thornback fish. It includes many species of fish with spines in their fins, such as perch, bass, and pike. These fish are primarily found in freshwater and marine environments and are characterized by their bony scales and pointed fin rays.
Acanthopterous
Acanthopterous refers to a group of fish characterized by having spiny fins. It is an adjective used in the classification of fish, particularly in the classification of bony fish, where it denotes a suborder or group within the Percomorphacea or Acanthopterygii. These fish often have sharp, pointy rays in their fins, which can be a defensive adaptation. Examples of acanthopterous fish include many species of perch, sunfish, and mackerel.
Acanthopterygian
Acanthopterygian refers to a subclass of bony fish characterized by having spiny rays in their fins. It includes many species of fish with棘like structures in their fin rays, such as perch, pike, and some types of tropical fish. The term is mainly used in scientific or zoological contexts.
Acanthopterygii
Acanthopterygii is a subclass of bony fish characterized by having spiny fins. These fish are also known as spiny-rayed fish and include species such as perch, bass, and mackerel. They are primarily found in freshwater and marine environments.
Acanthoscelides
Acanthoscelides is a genus of beetles, commonly known as bean weevils or seed bugs. They are pests that primarily feed on豆类and legume seeds, causing damage to crops and stored products.
Acanthosis
Acanthosis is a medical term referring to an abnormal thickening of the skin, characterized by an increase in the number and size of skin cells, particularly keratinocytes. It can present as rough or scaly patches and may be associated with various conditions or diseases, such as hormonal changes, genetic disorders, or skin irritations.
