Cancer is a group of many related diseases that begin in cells, the body's basic building blocks. The body is made up of many types of cells. Normally cells grow and divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. ...
Genital herpes is spread only by direct person-to-person contact. It is believed that a majority of sexually active adults carry the herpes virus. Part of the reason for the continued high infection rate is that most women infected with the herpes virus do not know that they are infected be...
Aging is a ubiquitous biological process that results in a progressive and irreversible decline in physical function across all organ systems that is induced by the accumulation of damage in response to a variety of stressors. Surprisingly, in 1925, research revealed that light intensity could impact...
As a consequence of adaptive immune memory, if an infectious agent makes a second attempt to infect a host, pathogen-specific memory T cells, memory B cells, and antibodies will mount a secondary immune response that is much more rapid and intense than the initial, primary response and, thus...
The AIDS model Any discussion of recent EIs must begin with the human immuno- deficiency virus (HIV) that causes AIDS. HIV has so far infected more than 60 million people worldwide33. Before jumping to humans an estimated 60–70 years ago34, perhaps as a consequence of the con- sumption...
It has been demonstrated that youths with CVDs experienced a substantial share in mortality burden [9]. For example, atherosclerosis can begin early in life and goes undetected for an extended time before developing into an advanced, clinically presentable, phase [10, 11]. Data from the Strong ...
DS Berns,B Rager 摘要: As the twenty-first century begins it becomes increasingly apparent that the twentieth century, which opened with the promise of the eradication of most infectious diseases, closed with the specter of the reemergence of many deadly infectious diseases that have a rapidly ...
The neurological examination should not be considered in isolation from that of the other body systems as it is part of the general physical examination. This is particularly important in newborn foals where systemic diseases can be associated with neurological dysfunction. As in adult horses, the ...
Simple linear regression analyses showed that advanced age significantly predicted worse emotion recognition, mentalizing and the social cognition total score (Fig. 1b and Extended Data Table 1). Linear mixed-effects models47 controlling for sex, age, education and country of origin revealed that the...
Overall, our study revealed a dissociation between observational and genetic evidence regarding the associations of loneliness with multiple diseases. These findings suggest that loneliness may serve as a potential surrogate marker rather than a causal risk factor for most diseases tested here....
