Fluctuating Asymmetry
Fluctuating asymmetry (FA), is a form of biological asymmetry, along with anti-symmetry and direction asymmetry. Fluctuating asymmetry refers to small, random deviations away from perfect bilateral symmetry. This deviation from perfection is thought to reflect the genetic and environmental pressures experienced throughout development, with greater pressures resulting in higher levels of asymmetry. Examples of FA in the human body include unequal sizes (asymmetry) of bilateral features in the face and body, such as left and right eyes, ears, wrists, breasts, testicles, and thighs. Research has exposed multiple factors that are associated with FA. As measuring FA can indicate developmental stability, it can also suggest the genetic fitness of an individual. This can further have an effect on mate attraction and sexual selection, as less asymmetry reflects greater developmental stability and subsequent fitness. Human physical health is also associated with FA. For example, young men w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infection
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses. Hosts can fight infections using their immune system. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response. Specific medications used to treat infections include antibiotics, antivirals, antifungals, antiprotozoals, and antihelminthics. Infectious diseases resulted in 9.2 million deaths in 2013 (about 17% of all deaths). The branch of medicine that focuses on infections is referred to as infectious disease. Types Infections are caused by infectious agents (pathogens) including: * Bacteria (e.g. ''Mycobacterium tuberculosis'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychopathy
Psychopathy, sometimes considered synonymous with sociopathy, is characterized by persistent Anti-social behaviour, antisocial behavior, impaired empathy and remorse, and Boldness, bold, Disinhibition, disinhibited, and Egotism, egotistical Behavior, traits. Different conceptions of psychopathy have been used throughout History of psychopathy, history that are only partly overlapping and may sometimes be contradictory. Hervey M. Cleckley, an American psychiatrist, influenced the initial diagnostic criteria for antisocial personality reaction/disturbance in the ''Diagnostic and Statistical Manual of Mental Disorders'' (''DSM''), as did American psychologist George E. Partridge. The ''DSM'' and ''International Classification of Diseases'' (ICD) subsequently introduced the diagnoses of antisocial personality disorder (ASPD) and Antisocial personality disorder#ICD-10, dissocial personality disorder (DPD) respectively, stating that these diagnoses have been referred to (or include ...
