AI Article Synopsis
- Total lipid and fatty acid composition was analyzed in the muscle and by-products (heads, shells, tails) of two shrimp species, Penaeus kerathurus and Metapenaeus monoceros, from Tunisian coasts.
- Shrimp by-products had lipid levels ranging from 2% to 3.15%, which were higher than the lipid content found in the shrimp muscle itself, with P. kerathurus showing a significant lipid content increase in the South compared to the North.
- Polyunsaturated fatty acids dominated the lipid composition in both species and regions, highlighting key fatty acids like C16:0, C20:5n-3, and C22:6n-3 as significant contributors to their overall lipid profiles.
Article Abstract
Total lipid and fatty acid composition was determined in the muscle and by-products (heads, shells and tails) of Penaeus kerathurus and Metapenaeus monoceros caught off the North and South coasts of Tunisia. Shrimp total lipid levels in by-products ranged between 2 to 3.15% (p < 0.05) and were higher than fat tissue levels in both groups. No significant difference was found between tissue and by-product lipid contents of M.monoceros from both regions. However, significantly higher lipid content was found in P.kerathurus from the South than the North area. The percentage of polyunsaturated fatty acids were important in the tissues and by-products of both species from both regions. Thus, polyunsaturated fatty acids constitute the major fraction followed by saturated fatty acids and monounsaturated. The main fatty acids in both shrimp species muscle and by-products were C16:0, C20:5n-3, C22:6n-3, C18:1n-9, C18:0, C16:1, C20:4 and C18:1n-7.

Economic impact of initial glaucoma treatment with selective laser trabeculoplasty on the Brazilian Public Health System.

Purpose: To evaluate the economic impact of the following initial treatment scenarios for glaucoma on the Brazilian Public Health System (SUS): (1) traditional continuous instillation of hypotensive eye drops and (2) single session of selective laser trabeculoplasty.
Methods: Economic impact was analyzed in three scenarios, from the least to the most conservative, for a hypothetical cohort of 5,000 individuals with open-angle glaucoma. Thereafter, projections were made on the basis of a glaucoma prevalence of 3% in the 2021 Brazilian population size.
Ketogenesis supports hepatic polyunsaturated fatty acid homeostasis via fatty acid elongation.

Division of Molecular Medicine, Department of Medicine, University of Minnesota Medical School, Minneapolis, MN, USA.
Ketogenesis is a dynamic metabolic conduit supporting hepatic fat oxidation particularly when carbohydrates are in short supply. Ketone bodies may be recycled into anabolic substrates, but a physiological role for this process has not been identified. Here, we use mass spectrometry-based C-isotope tracing and shotgun lipidomics to establish a link between hepatic ketogenesis and lipid anabolism.

The polar bear () is the only Arctic land mammal that dives into water to hunt. Despite thermal insulation provided by blubber and fur layers and low Arctic temperatures, their fur is typically observed to be free of ice. This study investigates the anti-icing properties of polar bear fur.

We evaluated the effects of breed and mineral source on heifer performance during periods of nutrient restriction and grazing. On day -7, ½ Angus × ½ Nelore (ANE) and Nelore (NE) heifers (12 heifers per breed; body weight, BW = 264 ± 35 kg; age = 15 ± 1 mo) were assigned to individual drylot pens to receive ad libitum Tifton 85 (Cynodon sp.) hay and white salt for 7 days.
