Summary
A rare gastric duplication cyst mimicked a kidney stone on X-ray in a 76-year-old woman. This case highlights the importance of considering gastric duplication cysts in elderly patients with abdominal pain.
Area of Science:
- Gastroenterology
- Radiology
- Surgical Oncology
Background:
- Gastric duplication cysts are rare congenital anomalies, typically diagnosed in childhood.
- Adult presentation is variable, making diagnosis challenging.
- Symptomatic gastric duplication cysts in the elderly are exceptionally uncommon.
Observation:
- A 76-year-old woman presented with abdominal pain.
- Initial X-ray revealed calcification mimicking a staghorn calculus (kidney stone).
- Abdominal CT identified gastric wall calcification, prompting further investigation.
Findings:
- Endoscopic ultrasound and biopsy confirmed gastric epithelium.
- A diagnosis of gastric duplication cyst was established.
- The cyst presented atypically, mimicking renal calculus on initial imaging.
Implications:
- This case underscores the diagnostic challenge of gastric duplication cysts in adults.
- It is the first reported instance of gastric duplication cyst mimicking staghorn calculus.
- Gastric duplication cyst should be included in the differential diagnosis for upper abdominal pain in the elderly.

Centrosome Duplication
5.0K
The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).

Gene Duplication and Divergence
8.0K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Fundamental Theorem of Calculus II
109
In calculus, the computation of the area under a continuous curve has been fundamentally simplified by applying the Fundamental Theorem of Calculus, Part 2. Rather than relying on the limiting process of summing infinitely many infinitesimal rectangles, this theorem permits direct evaluation using antiderivatives, thereby streamlining the process of definite integration.The Fundamental Theorem of Calculus, Part 2, states that if a function f(x) is continuous on a closed interval [a, b], then...

Initiation of Translation

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

Fundamental Theorem of Calculus I
102
Solving problems involving definite integrals requires a systematic approach that ensures clarity and efficiency. The first step is understanding the problem by identifying the calculated quantity, whether it involves accumulation, area, or a physical concept like force or probability. It is essential to recognize given conditions, such as the range of integration and any constraints that may affect the solution. Before computing, key properties of definite integrals should be analyzed to...
