Chromosome-level genome assembly and resequencing of camphor tree () provides insight into phylogeny and diversification of terpenoid and triglyceride biosynthesis of .

species attract attentions owing to their scents, medicinal properties, and ambiguous relationship in the phylogenetic tree. Here, we report a high-quality genome assembly of , based on which two whole-genome duplication (WGD) events were detected in the genome: one was shared with Magnoliales, and the other was unique to Lauraceae. Phylogenetic analyses illustrated that Lauraceae species formed a compact sister clade to the eudicots.

Autophagy is activated and might protect neurons from degeneration after traumatic brain injury.

Objective: To investigate changes of autophagy after traumatic brain injury (TBI) and its possible role.

Methods: Rat TBI model was established by controlled cortical injury system. Autophagic double membrane structure was detected by transmission electronic microscope.

[Expression of cathepsin-B and -D in rat's brain after traumatic brain injury].

Objective: To study the expression of cathepsin-B and -D in different time point after traumatic brain injury.

Methods: Traumatic brain injury (TBI) model was established on rats, cathepsin-B and cathepsin-D immunofluorescence staining and confocal microscope analysis were performed. Positive cells were counted by confocal microscope and image analysis techniques were used to determine the morphological changes in each group.
