In 1988, microbiologist Stanley Falkow developed a set of three Molecular Koch's postulates for identifying the microbial genes encoding virulence factors. First, the phenotype of a disease symptom must be associated with a specific genotype only found in pathogenic strains. Second, that symptom should not be present when the associated gene is ...
As per Falkow's original descriptions, the three postulates are: [1] "The phenotype or property under investigation should be associated with pathogenic members of a genus or pathogenic strains of a species. Specific inactivation of the gene(s) associated with the suspected virulence trait should lead to a measurable loss in pathogenicity or ...
Falkow is known as the father of the field of molecular microbial pathogenesis. [1] He formulated molecular Koch's postulates, which have guided the study of the microbial determinants of infectious diseases since the late 1980s. [2] Falkow spent over 50 years uncovering molecular mechanisms of how bacteria cause disease and how to disarm them. [1]
Personality pathology refers to enduring patterns of cognition, emotion, and behavior that negatively affect a person's adaptation. In psychiatry and clinical psychology , it is characterized by adaptive inflexibility, vicious cycles of maladaptive behavior, and emotional instability under stress.
Eysenck's three-factor model of personality was a causal theory of personality based on activation of reticular formation and limbic system. The reticular formation is a region in the brainstem that is involved in mediating arousal and consciousness. The limbic system is involved in mediating emotion, behavior, motivation, and long-term memory.
Dimensional models are intended to reflect what constitutes personality disorder symptomology according to a spectrum, rather than in a dichotomous way.As a result of this they have been used in three key ways; firstly to try to generate more accurate clinical diagnoses, secondly to develop more effective treatments and thirdly to determine the underlying etiology of disorders.
The cognitive model of abnormality is one of the dominant forces in academic psychology beginning in the 1970s and its appeal is partly attributed to the way it emphasizes the evaluation of internal mental processes such as perception, attention, memory, and problem-solving. The process allows psychologists to explain the development of mental ...
Personality Disorders: Theory, Research, and Treatment is a peer-reviewed academic journal published by the American Psychological Association. It was established in 2009 and covers research in personality psychology. [1] The current editor-in-chief is Joshua D. Miller, PhD. [2]
