The role of deep layer superior colliculus neurons in prepulse inhibition and the impact of spatial separation in male rats.

Prepulse inhibition (PPI) refers to the phenomenon in which a weak sensory stimulus before a strong one significantly reduces the startle reflex caused by the strong stimulus. Perceptual spatial separation, a phenomenon where auditory cues from the prepulse and background noise are distinguished in space, has been shown to enhance PPI. This study aims to investigate the neural modulation mechanisms of PPI by the spatial separation between the prepulse stimulus and background noise, particularly in the deep superior colliculus (deepSC).

Advances in biopharmaceutical products for hemophilia.

Hemophilia is caused by the deficiency of clotting factors due to a single genetic abnormality. Replacement therapies have evolved from plasma-derived to recombinant coagulation factor concentrates but continue to have certain limitations. Monoclonal antibodies are clinical prophylactic treatment options unaffected by inhibitors and have better compliance than coagulation factor concentrates for patients with hemophilia.

Transcriptomics, metabolomics and proteomics analyses reveal glyphosate tolerance mechanism in red swamp crayfish Procambarus clarkii.

Glyphosate (Gly), the world's most widely used herbicide in agriculture, can poison the red swamp crayfish, Procambarus clarkii, via spray drift and surface runoff into surface waters. However, there is a paucity of research on the mechanisms that affect crayfish tolerance to Gly at typical environmental concentrations. To address this research gap, we investigated the effects of Gly stress (0, 6, 12, 24, and 72 h) at different concentrations (0, 1.
