[ad_1] Basal cell nevus syndrome is a genetic disorder that causes abnormal growths on the skin, bones, and internal organs. It is caused by a mutation in the PTCH gene and is autosomal dominant. Symptoms include skin cancer, facial deformities, and nervous system malfunctions. Treatment varies depending on the specific complications. Basal cell nevus syndrome, […]
[ad_1] Basal body temperature increases slightly from conception until the end of the first trimester, which can be used to determine fertility and early pregnancy. A stable elevated temperature for more than 15 days after ovulation is a strong indicator of pregnancy. Temperature returns to normal at the end of the first trimester. A pregnant […]
[ad_1] A basal thermometer is more accurate than a regular fever thermometer and can be used orally, vaginally, or rectally. It is commonly used to determine ovulation and costs around $10 USD. Basal body temperature is the lowest temperature of a person at rest and can be monitored for family planning or detecting thyroid disorders. […]
[ad_1] Basal metazoans are the earliest animals in the evolutionary tree, including cnidarians, porifera, ctenophores, placozoans, and extinct species. Trichoplax adhaerens is the most basal living metazoan, with a small genome and unclear relation to other animals. Cnidarians were found to split from other metazoans earlier than sponges, challenging assumptions about evolution. Mesozoans are a […]
[ad_1] Basal amniotes are the earliest members of the amniote evolutionary tree, which includes reptiles and mammals. They evolved from reptiliomorphs and were the first animals to colonize the continental interior. Casineria, a small animal resembling a lizard, is one of the earliest known basal amniotes and pushed the known origin of amniotes back several […]
[ad_1] Basal vertebrates are the oldest and earliest vertebrates, including stem-group vertebrates. The evolution of basal vertebrates is still a mystery, but some possible theories exist. Tunicates are the closest living relatives of vertebrates, but not true vertebrates. Basal vertebrates quickly became a successful group, dominating the seas and leading to the evolution of large […]
[ad_1] The basal ganglia control movement and learned tasks, with damage causing motor problems. Parkinson’s, tardive dyskinesia, hemiballismus, and Huntington’s are common diseases. Tourette syndrome and OCD may also be linked to basal ganglia dysfunction. Understanding activity changes may lead to better treatment. The basal ganglia are a collection of nuclei in the brain responsible […]
[ad_1] Basal body temperature (BBT) is the lowest temperature a person’s body has during the day and is typically taken in the morning before becoming active. Women can use BBT changes to determine the best time to attempt pregnancy. Consistency is key for an accurate reading, and tracking BBT can help recognize patterns for ovulation. […]
[ad_1] Basal area is a forest management calculation used to assess site quality and stand density. It measures the area of individual trees and can be used to determine the value of lumber. Foresters use this calculation to manage forests and assess forest health. Basal area is a calculation used in forest management. There are […]
[ad_1] Fahr syndrome is a rare neurological disorder characterized by calcium deposits in the basal ganglia and cerebral cortex, causing symptoms such as dementia, motor function erosion, and involuntary movements. It is considered an inherited, genetically dominant condition with no known cure. Treatment focuses on symptom management. Basal ganglia calcification, better known as Fahr syndrome, […]
[ad_1] Basal tetrapods evolved from lobe-finned fish during the Devonian Period, and had features unique to tetrapods. Tiktaalik was an intermediate form between fish and amphibians, while Ichthyostega was one of the first true tetrapods with breakthroughs for terrestrial life. Basal tetrapods refer to the tetrapods (four-legged animals) at the root of the tetrapod evolutionary […]
[ad_1] A basal ganglia hemorrhage, often caused by high blood pressure, can lead to loss of consciousness, sensory and movement issues, and personality changes. Treatment involves supporting the patient and managing blood pressure with medication. Surgery may be an option in some cases. A basal ganglia hemorrhage bleeds from blood vessels in an area of […]
[ad_1] Basal cell skin cancer is the most common type of skin cancer and grows slowly, but can cause disfigurement if left untreated. It is caused by overexposure to UV radiation and can appear as subtle or noticeable changes to the skin. Treatment involves removal, and those who have had it before are at risk […]
[ad_1] Elevated basal body temperature can indicate infection, hyperthyroidism, ovulation, or pregnancy. Infections may be obvious or less so, and hyperthyroidism can cause restlessness, fatigue, and difficulty concentrating. Women may use their body temperature to track fertility. Those who track their basal body temperature each morning may periodically notice a higher-than-usual reading. An elevated basal […]
