Summary: This study quantified the efficiency of louver for juvenile green sturgeon under different conditions through controlled laboratory experiments. The results showed that fish size and approach velocity had the strongest influence on fish guidance efficiency, with poor efficiency observed for small fish at high velocities. Low velocities and daylight conditions allowed a greater proportion of the fish to remain upstream of the louver.

Summary: Using an optimized system for propagating human keratinocytes, researchers cultured skin samples from white and green sturgeons, generating epithelial cells capable of forming cross-linked protein envelopes. They identified two distinct forms of TGM1-like mRNA in these cells, which accounted for their envelope forming ability. The researchers also established continuous lines of white sturgeon epidermal cells and observed improvements in growth rate over multiple passages.

Summary: This study investigated the dietary differentiation between green sturgeon and white sturgeon in San Francisco Bay using carbon and nitrogen stable isotope analyses. The results showed that green sturgeon had more marine dietary sources compared to white sturgeon, and smaller individuals of both species had lower trophic levels. Additionally, larger individuals of both species had higher carbon values, indicating a higher consumption of marine food sources in adulthood.

Summary: Little is known about the distribution and ecology of juvenile green sturgeon within California's Central Valley and the San Francisco Bay Estuary. This study used acoustic biotelemetry to track the movements of juvenile green sturgeon and found a diversity of movement patterns among the tagged individuals. The quality of habitat varied between Delta and Bay habitats, and behaviors were likely optimized for fitness in response to environmental variation. The results suggest the importance of conserving the habitats relied upon by juvenile green sturgeon for long-term population stability.

Summary: Empirical evidence suggests that the distortions in the earth's magnetic field caused by underwater cables may impact the migration behavior of marine animals. This study examines the effects of the Trans Bay Cable (TBC) on the migration movements of adult green sturgeon. The results show that the energization of the cable is associated with a higher success rate of inbound migration, but a longer transit time for outbound migration. The cable energization does not significantly affect the migration path locations, but there may be a subtle relationship. Further migration-based studies are needed to investigate the impact of anthropogenic cables on marine species.

Summary: The intracellular chloride concentration plays a crucial role in GABA(A)R-mediated neurotransmission, involving both synaptic and extrasynaptic inhibition as well as excitation. The direction of Cl(-) and HCO3- fluxes is determined by underlying electrochemical gradient controlled by transporters and channels. The discovery of a GABA(A)R type requiring ATP consumption for chloride movement sheds new light on inhibitory signaling mechanisms.

Summary: This study investigates the effects of KCC2/NBCe1 interaction on the phosphorylation pattern and function of KCC2. The results show that KCC2 and NBCe1 interact in the mouse brain and this interaction may have pathophysiological relevance.

Summary: The study introduces a comprehensive thermodynamic model based on the eNRTL activity coefficient equation for accurate calculation of calcium carbonate scaling in highly saline produced waters. The model is capable of accurately calculating all phase equilibria and calorimetric properties under high temperature and saturation conditions.

Summary: Glutamate induces Ca2+ signaling in the suprachiasmatic nucleus (SCN) by activating intracellular mechanisms involving Na+ loads, Na+/K+-ATPase (NKA), and Na+/Ca2+-exchanger (NCX). The presence of Na+ loads leads to slower Ca2+ clearance and increased rebound Ca2+ suppression. However, even in the absence of external Na+, additional Ca2+ handlers are involved in the slower Ca2+ clearance induced by glutamate.

Summary: Adipose tissue under chronic inflammatory conditions such as obesity, atherosclerosis, and diabetes shows pro-inflammatory phenotypes and abnormal secretion. This study reveals that CD36 and Na/K-ATPase form a signaling complex in adipocytes, and oxidized LDL induces adipocyte exosome secretion through this complex. The adipocyte-derived exosomes promote pro-atherogenic phenotypes in macrophages, contributing to atherogenesis.
