Background In early 20th century, pneumonia was accountable for a large portion of infectious disease deaths1. In order to develop an effective vaccine against pneumonia, Frederick Griffith set out to study two different strains of the Streptococcus pneumoniae: a non-virulent strain with a rough appearance (R-strain) and a virulent strain with a smooth appearance (S-strain) due to an outer polysaccharide capsule2. This outer layer of the S-strain bacteria enabled them to withstand the host...

Bacterial Transformation ExpandIMPORTANT: In addition to wearing the appropriate personal protective equipment, be sure to take care to keep your face away from suspension cultures, and to avoid inhaling reagents. Do not touch your face while performing the experiment. Always wash your hands before and after every experiment. When you are ready to safely begin, check to make sure you have a tube or tubes of competent E. coli cells in your ice bucket. Then, transfer 50 µL from one of these tubes...

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Transformers are stationary electric machines that step up or down AC voltage. They are typically formed of primary and secondary coils or windings, where the voltage on the primary is stepped up or down at the secondary, or the other way around. When a voltage is applied to one of the windings and current flows in that winding, flux is induced in the magnetic core, coupling both windings. With an AC...

Since the Roman Empire, physicians have described the connection between alterations in function of specific parts of the body and specific disease states and have sought to further scientific understanding to improve bedside diagnosis. However, in this modern age of increasing technology within medical diagnostics, it...

Bacterial Transformation: Electroporation

The term “transformation” refers cellular ingestion of foreign DNA. In nature, transformation can occur in certain types of bacteria. In molecular biology, however, transformation is artificially induced through the creation of pores in the bacterial cell walls. Bacterial cells that are able to take up DNA from the environment are called competent cells. Electrocompetent cells can be produced in the laboratory and transformation of these cells can be achieve via the application of an...
FAQs
Physical transformation can affect psychological adjustment through reciprocal feedback between bodily experience and interpretation. A person’s self-perception may shape emotional responses and behavior, while those responses can influence how the person adapts to the change. This framework prevents researchers from treating bodily change as an isolated event and directs attention to ongoing interactions among body, mind, and social context.
Social feedback helps determine whether a bodily change becomes linked with confidence, distress, or altered identity. Reactions from other people may influence self-esteem and body image, while personal interpretations can shape responses to those reactions. Examining both sides clarifies why similar physical changes may be experienced differently and why psychological effects cannot be inferred from appearance alone.
Emotions, beliefs, and behavior are important mechanisms of adaptation. Emotional reactions can affect how a person understands a change, beliefs can guide its meaning, and behavior can express or reinforce that interpretation. Studying these interacting factors is especially relevant when people respond to disability, health conditions, or medical and lifestyle interventions, because adaptation includes psychological as well as bodily dimensions.
In psychological assessment, researchers can examine how a person interprets bodily change, how it relates to body image, identity, and self-esteem, and how social feedback shapes the experience. They can also consider adjustment to disability or responses to medical and lifestyle interventions. This broader view helps distinguish the physical event from its psychological meaning and adaptive consequences.
Counseling can use this framework to address distress associated with changed appearance, capabilities, or physiological state without assuming that every person will respond identically. Attention to self-perception, emotions, beliefs, behavior, and social feedback can help identify adjustment needs. The aim is to support adaptive coping while recognizing the individual’s interpretation and lived psychological response.
Health communication can present bodily change alongside the psychological processes that influence adaptation. Messages and supportive strategies may be more useful when they acknowledge body image, identity, self-esteem, and social feedback rather than focusing only on physical outcomes. This perspective is relevant to medical or lifestyle interventions because it connects information about bodily effects with emotional and behavioral adjustment.
