Summary
This study analyzed celiac trunk anatomy in Mexican cadavers, finding lower trifurcation rates and a high incidence of additional vessels. These variations are crucial for understanding abdominal arterial patterns.
Area of Science:
- Anatomy
- Vascular Biology
- Human Physiology
Background:
- The celiac trunk is the aorta's first major abdominal branch.
- Anatomic variations and accessory vessels are common.
- Understanding these variations is critical for clinical practice.
Purpose of the Study:
- To document the celiac trunk's pattern and variations in a Mexican population.
- To provide data on the prevalence of different celiac trunk configurations.
Main Methods:
- Dissection of 140 fresh Mexican cadavers (aged 18+).
- Exclusion criteria included prior abdominal surgery, trauma, or disease.
- Variations, diameters, accessory vessels, and origin levels were recorded using the Panagouli classification.
Main Results:
- Type I trifurcation (common hepatic, left gastric, splenic arteries) occurred in 43.6%.
- Additional branches (Type III) were observed in 47.9%; phrenic arteries originated from the celiac trunk in 41.4%.
- Higher-order branching (tetra- to heptafurcation) occurred in 27.7%; origin was T12-L1 in 90%.
Conclusions:
- Celiac trunk trifurcation rates were lower than previously reported.
- A significant proportion of cases exhibited accessory vessels, highlighting anatomical diversity.

01:14What is Variation?
18.7K
Apart from the measures of central tendency, distribution, outliers, and the changing characteristics of data with time, an important characteristic of any data set is its variation or spread. In some data sets, the data values are concentrated closely near the mean; in others, the data values are more widely spread out from the mean.
The range, standard deviation, standard error, and variance are the different measures of variation.
Range: The range is the difference between its maximum and...

02:53Conservative Site-specific Recombination and Phase Variation
6.9K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

8.1K
An important characteristic of any set of data is the variation in the data. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The most common measure of variation, or spread, is the standard deviation, which is the square root of variance.

01:11Anatomical Positions
20.6K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

01:18Variation of Atmospheric Pressure
4.2K
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...

02:26Comparing Copy Number Variations and SNPs
18.8K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
