Defense mechanisms are rooted in Freud’s theory of personality.According to his model, the mind has three dueling forces: the id (unconscious and primitive urges for food, comfort, and sex), the ...

Alkanes are major constituents of crude oil. They are also present at low concentrations in diverse non-contaminated because many living organisms produce them as chemo-attractants or as protecting ...

Inhibition studies using human liver microsomes showed that CYP3A4, 2B6, and 2C9 together contributed 19.0 ± 2.6% (mean ± 95%CI) to O-demethylation, 4.0 ± 0.7% to α-hydroxylation, and 7.6 ± 1.7% to ...

Structural and cellular assays and molecular dynamics simulations reveal the mechanism of action of γ-glutamyl carboxylase, which involves cholesterol and vitamin K. Protein kinase R-like ...

A multifactorial approach should be used to account for all the factors involved-that is, the internal and external risk factors as well as the inciting event (the injury mechanism). Although such ...

Reaction formation is a defense mechanism in which people express the opposite of their true feelings, sometimes to an exaggerated extent. For instance, a man who feels insecure about his ...

The biochemical mechanisms through which folate exerts an influence on neuropsychiatric status are likely to involve the 1-carbon cycle, a pathway essential to many transmethylation reactions ...

The findings shed light on how socio-sexual preferences adapt for survival and health in mammals. Understanding these neural mechanisms could inform studies on social behavior and stress responses in ...

Get Instant Summarized Text (Gist) Artificial motors have been developed to mimic muscle proteins, converting chemical energy into mechanical work. These nanoscale rotary motors, embedded in ...
