Unearthing the Unexpected: First Report of Ossa Cordis in a Human Heart.
Am J Forensic Med Pathol
January 2025
From the Department of Pathology, Wake Forest University School of Medicine, Winston-Salem, NC.
The ossa cordis (OC), or cardiac bone, is a bony structure within the cardiac skeleton of mammals, believed to maintain heart shape during systole and enhance contraction efficiency. Found in large mammals, especially ruminants, and has recently been described in chimpanzees; however, OC has not previously been described in humans. Herein, we present an incidental finding of OC in the heart of a 39-year-old man who suffered a stab wound to chest.

A medical specialty prediction system for remote diagnosis can reduce the unexpected costs incurred by first-visit patients who visit the wrong hospital department for their symptoms. To develop medical specialty prediction systems, several researchers have explored clinical predictive models using real medical text data. Medical text data include large amounts of information regarding patients, which increases the sequence length.

Rejection of the concept of hemiurid genus Pulmovermis (Digenea: Hemiuridae) and other taxonomic propositions: new morphological and molecular data regarding Lecithochirium cyanovitellosum (Coil and Kuntz, 1960) Urabe and Sokolov, comb. nov. (formerly Pulmovermis cyanovitellosus).

Pulmovermis cyanovitellosus Coil and Kuntz, 1960 is a species of hemiurid trematode that localizes in the lung of sea snakes, an unusual trait for this group of parasites. Recent molecular phylogenetic studies based on 28S rRNA gene sequences have shown that this species is closely related to members of the genus Lecithochirium Lühe, 1901. This finding is unexpected given that Pulmovermis Coil and Kuntz, 1960 and Lecithochirium are currently classified in different subfamilies of Hemiuridae (Pulmoverminae Sandars, 1961 vs.

Some key secondary metabolism genes are important for driving the infection process of entomopathogenic fungi; however, their chemical substance basis has not been well investigated. Here, mixtures of polyol lipids are discovered, which are synthesized through iterative chain transfer-esterification-hydrolysis cycles catalyzed by serine hydrolase during the release of online highly reducing polyketide intermediates. Importantly, an gene knockout experiment revealed that the synthesis of polyol lipids is necessary for rodlet layer formation on the cell wall of .
