Introduction to Enzymes

Introduction to Enzymes

The use of enzymes by humans dates to 7000 BCE. Humans first used enzymes to ferment sugars and produce alcohol without knowing that this was an enzyme-catalyzed reaction. Wilhelm Kuhne coined the term 'enzyme' in 1877 from the Greek words ‘en’ meaning ‘in’ or ‘within’ and ‘zyme’ meaning ‘yeast.’
Most enzymes are proteins that speed up biochemical reactions without being consumed. Enzymes contain one or more active sites that...

Criticisms of the Evolutionary Perspective

Criticisms of the Evolutionary Perspective

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

Social Traps

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Emerging Adulthood

Emerging Adulthood

Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Free Energy and Equilibrium

Free Energy and Equilibrium

The free energy change for a process may be viewed as a measure of its driving force. A negative value for ΔG represents a driving force for the process in the forward direction, while a positive value represents a driving force for the process in the reverse direction. When ΔGrxn is zero, the forward and reverse driving forces are equal, and the process occurs in both directions at the same rate (the system is at equilibrium).
Recall that Q is the numerical value of the mass action...

The Wave Nature of Light

The Wave Nature of Light

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Area of Science:

Medical History
Neurosurgery History
Trauma Management History

Background:

The historical understanding of traumatic brain injury (TBI) evolved significantly over centuries.
Early medical practitioners grappled with the complex relationship between cranial trauma, consciousness, and intracranial bleeding.

Observation:

Pioneers like Dionis, Le Dran, and Pott established connections between disturbed consciousness and blood extravasation following head injuries.
Latta highlighted the role of meningeal arteries in hematoma formation.
Debates arose regarding the efficacy and safety of different trepanation instruments and techniques.

Findings:

Pathophysiological explanations for TBI symptoms emerged, emphasizing cerebral injury over superficial indicators like periosteal separation.
Benjamin Bell advocated for trepanation primarily in cases of clinical deterioration due to hemorrhagic extravasation.
Surgical instrument evolution favored cylindrical trepan crowns and techniques ensuring controlled drilling depth.

Implications:

These historical developments laid the groundwork for modern neurosurgical approaches to TBI.
The refinement of diagnostic criteria and surgical techniques improved the management of intracranial hematomas.
Understanding the historical progression of TBI management offers valuable insights into contemporary neurosurgical practices.
