1. The incorporation of (14)C into the brain glycogen of conscious rabbits with labelled glucose, bicarbonate and glutamate as precursors has been studied. 2. Substantial incorporation from all these precursors was demonstrated after an interval of 5hr. from their injection. 3. With [(14)C]glucose maximal incorporation occurred at about 8hr. from the time of injection. 4. Hydrocortisone led to increased incorporation of (14)C from labelled glucose. 5. Some comparisons between the turnover of brain glycogen and that of skeletal and cardiac muscle are reported.

Local heating of the activity area for nursing piglets is crucial for piglet health and the energy efficiency of barn climate control. Traditional heating methods using lamps or covers lack precise control, result in significant energy waste, and cannot be dynamically adjusted according to piglet age or changing environmental temperatures. To address these issues, this study designed a Programmable Logic Controller (PLC)-based thermal insulation box for nursing piglets, utilizing a strip heater instead of the conventional round heating lamp.

Background: Disturbed white adipose tissue function is important for cardiometabolic risk and metabolic syndrome (MetS). Whether this involves adipose lipid turnover (lipolysis and synthesis of triglycerides) is unknown and was presently investigated in subcutaneous adipose tissue, the body's largest fat depot.
Methods: In cross-sectional studies in 78 subjects, adipose lipid age, representing overall lipid turnover (mobilization and storage), and lipid storage capacity were assessed by the incorporation of atmospheric C into adipose lipids.
The tusk of the male narwhal is a prolonged canine tooth, reaching a size of up to 3 m in length. The tusk erupts through the young narwhal's upper left lip and, over time, develops into an elongated structure composed of dentine growth layers with an outer coating of cementum. In this study, we utilized bomb radiocarbon (C) to estimate the ages of three narwhal tusks, which allowed us to validate the assumption that one growth layer is deposited annually in narwhal tusks.

Seed development requires substantial metabolic resources and is influenced by adverse environmental conditions. However, the ability of plants to produce viable seeds under restrictive conditions suggests the existence of mechanisms that make this process less sensitive to environmental stress. Uncovering their regulation could lead to the development of genotypes better adapted to stressful conditions.
