Constitutive androstane receptor (CAR) functions as a tumor suppressor via regulating stemness in liver cancer.

Constitutive androstane receptor (CAR) is a xenosensor that is almost exclusively expressed in the liver. Studies in rodents suggest an oncogenic role for CAR in liver cancer, but its role in human liver cancer is unclear. We aimed to investigate the functional roles of CAR in human liver cancer with a focus on the liver cancer stem cells.

Ecological interactions, host plant defenses, and control strategies in managing soybean looper, (Lepidoptera: Noctuidae).

Soybean looper (SBL), (Walker 1858) (Lepidoptera: Noctuidae), is one of the most damaging insect pests of soybean, (L.) Merr., in the mid-south region of the United States, and causes significant economic losses to cotton, sunflower, tomato, and tobacco crops in the United States, Brazil, and Argentina.

Muffled olfactory and sensory cues from the reproductive stage soybean selectively reduce oviposition of a major polyphagous herbivore, fall armyworm (Spodoptera frugiperda).

Background: While the mother knows best/preference performance hypothesis has been well tested in natural ecosystems, how these ecological principles differ in agroecosystems is less explored. In this study, we investigated the ovipositional preference and offspring performance of fall armyworm (FAW) across vegetative and reproductive stages of soybean.

Results: We examined trichomes, volatile organic compounds (VOCs) and assessed electroantennogram (EAG) measurements to understand how olfactory responses are affected by volatiles at different phenological stages during photoperiodism (photophase and scotophase).

Proportional myoelectric control of a virtual bionic arm in participants with hemiparesis, muscle spasticity, and impaired range of motion.

Background: This research aims to improve the control of assistive devices for individuals with hemiparesis after stroke by providing intuitive and proportional motor control. Stroke is the leading cause of disability in the United States, with 80% of stroke-related disability coming in the form of hemiparesis, presented as weakness or paresis on half of the body. Current assistive exoskeletonscontrolled via electromyography do not allow for fine force regulation.
