Histone Variants at the Centromere02:30

Histone Variants at the Centromere

5.1K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

Stress on an Oblique Plane

1.1K
Understanding stress on an oblique plane under axial loading is pivotal in material mechanics. This analysis offers insight into a material's durability and strength, which is crucial for civil engineering and structural design. Axial loading refers to force application along the material's central axis, causing compression or elongation and leading to normal stress. Normal stress occurs when a force acts perpendicularly to the material's area, resulting in compressive or tensile...

Principles of Pharmacogenetics: Types of Genetic Variants

4
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

Arteries of Lower Limbs01:20

Arteries of Lower Limbs

4.9K
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Arteries and Arterioles01:16

Arteries and Arterioles

6.9K
Arteries, the vasculature responsible for transporting blood from the heart, possess robust walls capable of enduring the elevated pressures exerted by the heartbeat. Arteries near the heart are especially thick-walled and enriched with elastic fibers across their three tunics, classifying them as elastic or conducting arteries. These arteries, usually with a diameter exceeding 10 mm, are characterized by their ability to dilate in response to the blood pumped from the heart's ventricles...

Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

2.5K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Area of Science:

  • Anatomy
  • Vascular Surgery

Background:

  • The columellar artery (CoA), a branch of the facial artery, supplies the nasal tip.
  • Numerous anatomical variations of the CoA exist, impacting surgical planning.

Observation:

  • A cadaveric dissection revealed an unusual CoA variant.
  • This variant exhibited a direct anastomosis with the right infraorbital artery.

Findings:

  • A novel oblique and third CoA variant was identified, anastomosing with the contralateral infraorbital artery.
  • This specific vascular configuration has not been previously reported or illustrated.

Implications:

  • Preprocedural vascular assessment of the perioral region is crucial for optimizing surgical outcomes.
  • Surgeons operating in the columellar region must be aware of this CoA variant for safe and effective practice.
