Different combinations of subunits yield nAChRs that differ considerably in their functional and pharmacological properties [ 1 ]. Furthermore Moretti et al.

This research examined the impact of facial age appearance on hiring, and impressions of fitness as the underlying mechanism. In two experimental hiring simulations, one with lay persons and one with Human Resource professionals, participants evaluated a chronologically older or younger candidate as indicated by date of birth and age label with either younger or older facial age appearance as indicated by a photograph. In both studies, older-looking candidates received lower hireability ratings, due to less favorable fitness impressions. In addition, Study 1 showed that this age bias was reduced when the candidates provided counter-stereotypic information about their fitness. Study 2 showed that facial age-based discrimination is less prevalent in jobs with less costumer contact e.

In a world filled with big data, mathematical models, and statistics, the development of strong quantitative skills is becoming increasingly critical for modern biologists. Teachers in this field must understand how students acquire quantitative skills and explore barriers experienced by students when developing these skills. In this study, we examine the interrelationships among gender, grit, and math confidence for student performance on a pre—post quantitative skills assessment and overall performance in an undergraduate biology course.
Acetylcholine, exquisitely evolved as a neurotransmitter, is made and released by the neurons that take the integrated output of the central nervous system throughout the body. At both neuromuscular junctions and autonomic ganglia, acetylcholine activates synaptic ion channels that take their name from the plant alkaloid nicotine, which is a mimic of the natural neurotransmitter. This chapter begins with the scientific discoveries related to the nicotinic acetylcholine receptors nAChR of the neuromuscular junction and how resulting insights led to an understanding of the fundamentals of synaptic transmission. The nAChR are one member of a superfamily of ligand-gated ion channels, and although in the brain excitatory neurotransmission is mediated by another family of synaptic receptors that are gated by glutamate, nicotinic receptors are important modulators of brain function and significant targets for drug development.
