Sampling Plans01:23

Sampling Plans

908
Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

Planning Nursing Care I

5.6K
The planning phase of the nursing process helps nurses set priorities, outline patient-centered goals and expected outcomes, and tailor nursing interventions to align with the aligned care plan. Through the planning phase, the nurse applies critical thinking skills to align and develop interventions according to the patient's needs. It provides continuity of care allowing patients to receive the maximum benefit from treatment. It serves as a pilot plan for allocating individual staff to a...

Lumber Defects01:23

Lumber Defects

490
Lumber defects, which can affect both the appearance and structural integrity of wood, include a variety of growth and manufacturing flaws. Growth defects such as knots and knotholes occur where branches were once attached to the tree trunk, with knotholes forming when these knots fall out. Other natural defects include decay and insect damage, which compromise the wood's strength and durability.
Shakes are minor fractures that run along or across the wood's annual rings, while wane is...

Planning Nursing Care II

3.6K
A nursing care plan can present in two forms: informal and formal. Informal is a care plan for the individual use of the nurse and goals they wish to accomplish during their shift. Informal care plans are not included in the patient chart. A formal nursing care plan is a written or computerized guide that organizes patient care. It is further subdivided into two: standardized and individualized care plans. Standardized care plans are pre-populated care plans for specific patient populations,...

Protein Complex Assembly02:41

Protein Complex Assembly

16.7K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Protein Complexes with Interchangeable Parts01:57

Protein Complexes with Interchangeable Parts

2.9K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Summary
This summary is machine-generated.

Three-dimensional (3D) computer planning aids complex head and neck reconstructions, particularly for mandibular defects. Routine post-operative 3D analysis is proposed to objectively determine surgical success in these challenging cases.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Three-dimensional (3D) computer planning has been available for over two decades for complex head and neck osseous reconstructions.
  • Despite its availability and advancements, 3D computer planning has seen limited widespread adoption in clinical practice.
  • The objective evidence supporting claims of improved surgical precision, reduced operating time, and enhanced functional outcomes remains scarce.

Purpose of the Study:

  • To review the recent literature supporting the use of 3D computer planning for complex mandibular osseous defects.
  • To highlight a case example demonstrating the critical role of 3D modeling in virtual surgical planning.
  • To propose the routine implementation of post-operative 3D analysis for assessing surgical success.

Main Methods:

  • Literature review focusing on studies evaluating 3D computer planning for mandibular reconstruction.
  • Presentation of a clinical case illustrating the application of 3D modeling in virtual surgical planning.
  • Discussion on the utility of post-operative 3D analysis for outcome assessment.

Main Results:

  • The reviewed literature provides limited objective evidence for the benefits of 3D computer planning in complex osseous reconstructions.
  • A case example demonstrated the significant role of 3D modeling, especially during the virtual surgical planning phase.
  • The study emphasizes the need for objective outcome evaluation to define the role of 3D planning.

Conclusions:

  • 3D computer planning holds potential for complex mandibular reconstructions, but its widespread adoption is hindered by limited objective evidence.
  • Routine post-operative 3D analysis is proposed as a crucial component for objectively evaluating surgical success.
  • Further critical evaluation of outcomes is necessary to better define the precise applications of 3D computer planning in complex osseous defect reconstruction.
