Detailed Structure and Function of Lymph Nodes01:23

Detailed Structure and Function of Lymph Nodes

5.1K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Node Analysis for AC Circuits01:14

Node Analysis for AC Circuits

682
Consider an angioplasty system featuring a catheter equipped with a turbine, a critical tool for removing plaque deposits from coronary arteries. This intricate medical device operates using a circuit model reminiscent of a dual-node RLC circuit powered by a current-controlled voltage source.
To unravel the complexities of this system, nodal analysis is employed, a powerful technique founded on Kirchhoff's current law (KCL), which remains valid for phasors. AC circuits can effectively be...

Lymphatic Vessels and Lymph Transport01:16

Lymphatic Vessels and Lymph Transport

23.5K
Lymphatic vessels, known as lymphatics, are crucial in transporting lymph from peripheral tissues to our venous system. This process begins with lymph entering through tiny capillaries that branch through tissues. These capillaries have unique features such as larger diameters, thinner walls, and a distinctive one-way valve system formed by overlapping endothelial cells.
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular...

Fluid Connective Tissues: Blood and Lymph

18.7K
Blood and lymph are fluid connective tissues. They contain cells, also known as formed elements, circulating in a liquid extracellular matrix, the plasma. The formed elements are derived from hematopoietic stem cells in the bone marrow. Blood and lymph connect all vital parts and carry nutrients, oxygen, and other essential molecules like antibodies.
Blood
The blood flows through blood vessels— arteries, capillaries, and veins. Blood plasma is primarily made of proteins, solutes, and...

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

414
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Muscles of the Anterior Neck01:26

Muscles of the Anterior Neck

4.9K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Area of Science:

  • Oncology
  • Surgical Pathology
  • Medical Devices

Background:

  • Lymph node (LN) metastasis is a critical prognostic factor in oral squamous cell carcinoma (OSCC).
  • Accurate identification of the number and location of positive LNs is essential for patient prognosis.
  • Surgeons face challenges in precisely locating LNs during neck dissection specimens.

Purpose of the Study:

  • To introduce and evaluate a novel optical lymph node detection system (OLNDS) for improving LN localization in neck resection specimens.
  • To assess the efficacy of the OLNDS in increasing the number of identified LNs and reducing false detection rates.

Main Methods:

  • A prospective study was conducted involving the use of the OLNDS in neck resection specimens.
  • Comparison of LN detection rates and false detection rates between the OLNDS-assisted method and traditional methods.
  • Statistical analysis to determine the significance of observed differences (P-values provided).

Main Results:

  • The OLNDS significantly improved the ease of LN location.
  • A significantly higher number of LNs were identified with the OLNDS (P=0.006).
  • The false detection rate was significantly reduced compared to traditional methods (P=0.0034).

Conclusions:

  • The optical lymph node detection system (OLNDS) is a valuable adjunct for traditional methods in neck dissection.
  • OLNDS facilitates easier and more accurate LN identification, potentially enhancing the study of LN metastasis in OSCC prognosis.
