HEAD TRAUMA AND OLFACTORY FUNCTION

Head trauma and olfactory function

Olfactory impairment is a well-established sequela of head injury.The presence and degree of olfactory dysfunction is dependent on severity of head trauma, duration of posttraumatic amnesia, injuries obtained, and as more recently established, age.Deficits in smell can be conductive or neurosensory, contingent on location of injury.The former may b

Lignin concentrations in phloem and outer bark are not associated with resistance to mountain pine beetle among high elevation pines.

A key component in understanding plant-insect interactions is the nature of host defenses.Research on defense traits among Pinus species has focused on specialized metabolites and axial resin ducts, but the role of lignin in defense within diverse systems is unclear.We investigated lignin levels in the outer bark and phloem of P.longaeva, P.balfour
