The character of changes in molar correlation of cholesterol and phospholipids has been studied at different functional states in frog myelinic nerve and squid nonmyelinic nerve trunk. The correlation cholesterol/phospholipid (C/P) found for both nerves in rest increases at temperature 38 degrees C. The electrical stimulation on the background of higher temperature action leads to unequal shift of C/P: the increase compared with the rest in frog and decrease in squid.

Patient advocacy is a duty for professional nurses; however, not all nurses are empowered to advocate for meeting patients' needs. Participation in labor unions may serve as a venue for nurses with limited institutional decision-making authority to advocate for patient needs; however, unionization can be a time-intensive and fraught process. This study examined how nurses participating in a new union in an urban United States hospital described their reasons for participating in a labor union during collective bargaining.

Background: The cellular prion protein (PrP), a glycoprotein encoded by the PRNP gene, is known to modulate muscle mass and exercise capacity. However, the role of PrP in the maintenance and regeneration of skeletal muscle during ageing remains unclear.
Methods: This study investigated the change in PrP expression during muscle formation using C2C12 cells and evaluated muscle function in Prnp wild-type (WT) and knock-out (KO) mice at different ages (1, 9 and 15 months).

High spatial or temporal variability in community composition makes it challenging for natural resource managers to predict ecosystem trajectories at scales relevant to management. This is commonly the case in nearshore marine environments, where the frequency and intensity of disturbance events vary at the sub-kilometer to meter scale, creating a patchwork of successional stages within a single ecosystem. The successional stage of a community impacts its stability, recovery potential, and trajectory over time in predictable ways.

Stomata control plant water loss and photosynthetic carbon gain. Developing more generalized and accurate stomatal models is essential for earth system models and predicting responses under novel environmental conditions associated with global change. Plant optimality theories offer one promising approach, but most such theories assume that stomatal conductance maximizes photosynthetic net carbon assimilation subject to some cost or constraint of water.

Background/purpose: The use of finite element (FE) analysis in implant biomechanics offers many advantages over other approaches in simulating the complexity of clinical situations. The aim of this study was to perform an optimization analysis of dental implants with different thread designs in three types of bone quality.
Materials And Methods: The three-dimensional FE model of a mandibular bone block with a screw-shaped dental implant and superstructure was simulated.
