Summary
Children with beta-thalassemia major show distinct dermatoglyphic patterns, including more whorls and an increased "atd" angle. These genetic markers may also appear in parents, suggesting carrier status.
Area of Science:
- Dermatoglyphics
- Human Genetics
- Pediatrics
Context:
- Beta-thalassemia major is a severe inherited blood disorder.
- Dermatoglyphic patterns (fingerprints) are unique and can be influenced by genetic factors.
- Understanding genetic markers aids in diagnosis and carrier identification.
Purpose:
- To investigate dermatoglyphic differences in children with beta-thalassemia major compared to healthy controls.
- To examine dermatoglyphic features in parents of children with beta-thalassemia major.
- To explore the potential of dermatoglyphics as a phenotypic marker for heterozygous carriers.
Summary:
- The study analyzed finger patterns, 'atd' angle, and ridge counts in 70 healthy children, 39 children with beta-thalassemia major, and 47 of their parents.
- Patients with beta-thalassemia major exhibited a higher prevalence of whorls, increased 'atd' angle, and elevated ridge counts.
- Parents showed a less pronounced increase in whorls, suggesting these dermatoglyphic changes may indicate heterozygous carrier status for the beta-thalassemia gene.
Impact:
- Identifies specific dermatoglyphic traits associated with beta-thalassemia major.
- Provides potential non-invasive markers for identifying carriers of the beta-thalassemia gene.
- Contributes to the understanding of genetic expression in inherited blood disorders.

Anatomy of the Brain: Major Regions
10.6K
The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...

Major Organs of the Digestive System

The digestive system is responsible for the ingestion of food, secretion of enzymes, mixing and digesting food, absorption of the nutrients and defecation. The human digestive system consists of two major parts: the gastrointestinal tract and the accessory digestive organs.

Major Hormones and Their Functions
2.0K
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Major Losses in Pipes
2.0K
When a fluid flows through a pipe, it experiences energy losses due to frictional resistance along the pipe walls, known as major losses. These energy losses result in a pressure drop, which varies based on the flow conditions — whether laminar or turbulent — and the specific physical properties of the fluid and pipe.
Fluid flow can be classified as laminar or turbulent, primarily based on the Reynolds number. This dimensionless number reflects the relative influence of inertial to viscous...

Major Somatic Sensory Pathways
2.9K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Collagens are the Major Structural Proteins of ECM
5.8K
Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Collagen fiber is made from fibrous protein subunits linked together to form a long, straight fiber. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. These fibers hold connective tissues together, even during the body's movement.
