Article Synopsis
  • Weedy rice, a close relative of cultivated rice, infests fields globally and reduces crop yields, prompting US farmers to adopt herbicide-resistant (HR) rice varieties to combat this issue.
  • The introduction of HR and hybrid rice cultivars changed the dynamics of crop-weed hybridization, allowing for adaptive introgression and altering selective pressures.
  • A study analyzing 178 weedy rice samples showed geographical shifts and genetic mechanisms in response to herbicide selection, revealing the adaptation of weedy rice through diverse genetic pathways.

Eight monoterpene indole alkaloids (-), including one new picraline-type alkaloid, 2-hydroxyakuammiline () and seven known compounds: akuammigine (), akuammine (), akuammidine (), akuammiline (), akuammiline N-oxide (), akuammiline (), rhazimol (), and alstonine () were isolated from the seeds of . Structure elucidation was done by analysis of their MS and NMR spectroscopic data. The antiplasmodial effects of compounds - were moderate.

Objective: Aging-related changes and caregiver burden may increase the risk for sleep disturbances among older caregivers, yet few studies have examined the prevalence of insomnia and daytime sleepiness in this group. We examined the relationship of caregiver status with insomnia and daytime sleepiness among persons of advanced age (>75 years of age).

Design: Cross-sectional.

Background: The BRIGhTMIND study was a double-blind RCT comparing repetitive transcranial magnetic stimulation at a standard simulation site (the "F3" location given by the International 10-20 system, F3-rTMS) versus connectivity-guided intermittent theta burst stimulation (cgiTBS) for treatment-resistant depression. This present study reports the acceptability, safety, and tolerability of F3-rTMS versus cgiTBS.

Methods: The present study used quantitative and qualitative methods.

Background: Sleep disturbances are common and distressing for people with dementia and their families. Non-pharmacological interventions should be first-line management, avoiding harmful pharmacological side-effects, but there is none with known effectiveness. We aimed to establish whether DREAMS START, a multicomponent intervention, reduced sleep disturbance in people with dementia living at home compared with usual care.
