The Auditory Ossicles01:11

The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
Bone Markings01:26

Bone Markings

Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
Compact Bone01:27

Compact Bone

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
Robbers Cave04:49

Robbers Cave

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension could be...

Summary
This summary is machine-generated.

Nitrile gloves can negatively affect isoelectric focusing (IEF) experiments, particularly in erythropoietin anti-doping analysis. Researchers must consider gloves as potential sources of analytical error, not just protective gear.

Area of Science:

  • Analytical Chemistry
  • Biochemistry
  • Forensic Science

Background:

  • Isoelectric focusing (IEF) is a key technique for protein separation and analysis.
  • Accurate IEF results are critical in applications like anti-doping control.
  • Potential sources of experimental artifact require careful investigation.

Purpose of the Study:

  • To investigate the impact of nitrile gloves on isoelectric focusing (IEF) experiments.
  • To identify if glove material can cause distortions in protein patterns.
  • To highlight the importance of considering all experimental components in analytical processes.

Main Methods:

  • Performed isoelectric focusing (IEF) experiments for erythropoietin analysis.
  • Observed the effects of wearing nitrile gloves during the application of the catholyte strip.
  • Compared IEF patterns obtained with and without nitrile glove use.

Main Results:

  • Wearing nitrile gloves during catholyte strip application led to significant distortions in the erythropoietin IEF pattern.
  • These distortions suggest a deleterious impact of nitrile gloves on the IEF experiment.
  • The presence of gloves introduced an unexpected variable into the analytical process.

Conclusions:

  • Gloves, specifically nitrile, can adversely affect IEF experimental outcomes.
  • Analytical personnel must be aware that gloves are not inert and can interfere with results.
  • Re-evaluation of laboratory protocols to account for glove-induced artifacts is recommended for accurate anti-doping control.
