Candidate genes associated with fatty acid compositions in north American Atlantic salmon (Salmo salar).

Fatty acids are a requirement for normal development, however, since humans are unable to de novo produce essential fatty acids, they must be obtained from diet. Atlantic salmon is a major dietary source of nutritious and digestible fatty acids. Here, we set out to uncover the genomic basis of individual fatty acids and indices (saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, n-3, and n-6) in 208 North American Atlantic salmon, to understand selection potential toward increasing relative quantities of essential fatty acids and to identify candidate genes for future research.

On Angles in Higher Order Brillouin Tessellations and Related Tilings in the Plane.

For a locally finite set in , the order- Brillouin tessellations form an infinite sequence of convex face-to-face tilings of the plane. If the set is coarsely dense and generic, then the corresponding infinite sequences of minimum and maximum angles are both monotonic in . As an example, a stationary Poisson point process in is locally finite, coarsely dense, and generic with probability one.

Functional insights of novel Bathyarchaeia reveal metabolic versatility in their role in peatlands of the Peruvian Amazon.

Unlabelled: The decomposition of soil organic carbon within tropical peatlands is influenced by the functional composition of the microbial community. In this study, building upon our previous work, we recovered a total of 28 metagenome-assembled genomes (MAGs) classified as Bathyarchaeia from the tropical peatlands of the Pastaza-Marañón Foreland Basin (PMFB) in the Amazon. Using phylogenomic analyses, we identified nine genus-level clades to have representatives from the PMFB, with four forming a putative novel family (" Paludivitaceae") endemic to peatlands.

Microbial occurrence and symbiont detection in a global sample of lichen metagenomes.

In lichen research, metagenomes are increasingly being used for evaluating symbiont composition and metabolic potential, but the overall content and limitations of these metagenomes have not been assessed. We reassembled over 400 publicly available metagenomes, generated metagenome-assembled genomes (MAGs), constructed phylogenomic trees, and mapped MAG occurrence and frequency across the data set. Ninety-seven percent of the 1,000 recovered MAGs were bacterial or the fungal symbiont that provides most cellular mass.

Creeping Cold Nodules: Ascending Lower Extremity Nodules in an Immunocompromised Patient.

Non-tuberculous mycobacterium (NTM) infection can cause a broad range of pathology, especially in an immunocompromised patient. We report a case of ascending lower extremity nodules in a renal transplant patient that were found to be caused by , an NTM. We discuss the clinical evaluation and workup of this patient and why NTM infections may require a high degree of clinical suspicion to properly diagnose and treat.
