Acinar cell carcinoma of the pancreas: clinical and cytomorphologic characteristics.

Korean journal of pathology

Toll AD, Hruban RH, Ali SZ.
PMID: 23667367
Korean J Pathol. 2013 Apr;47(2):93-9. doi: 10.4132/KoreanJPathol.2013.47.2.93. Epub 2013 Apr 24.

Acinar cell carcinoma is a rare malignant epithelial neoplasm with predominantly exocrine acinar differentiation and is seen primarily in older men (mean age, 62 years). The presenting symptoms are usually non-specific, and jaundice is often not present. Symptoms relating...

Dissolved Gases and Ice Fracturing During the Freezing of a Multicellular Organism: Lessons from Tardigrades.

BioResearch open access

Purpose. Cryoprotectants (CPA) for stem cells from umbilical cord blood (UCB) have been widely developed based on empirical evidence, but there is no consensus on a standard protocol of preservation of the UCB cells. Methods. In this study, UCB...

How Next-Generation Sequencing Has Aided Our Understanding of the Sequence Composition and Origin of B Chromosomes.

Genes

Ruban A, Schmutzer T, Scholz U, Houben A.
PMID: 29068386
Genes (Basel). 2017 Oct 25;8(11). doi: 10.3390/genes8110294.

Accessory, supernumerary, or-most simply-B chromosomes, are found in many eukaryotic karyotypes. These small chromosomes do not follow the usual pattern of segregation, but rather are transmitted in a higher than expected frequency. As increasingly being demonstrated by next-generation sequencing...
