Development of the Lymphatic System01:15

Development of the Lymphatic System

2.0K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Histone Modification02:32

Histone Modification

16.0K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone...

Spreading of Chromatin Modifications02:25

Spreading of Chromatin Modifications

9.4K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Introduction to Lymphatic and Immune System01:22

Introduction to Lymphatic and Immune System

16.7K
Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are...

Functions of the Lymphatic and Immune System

6.6K
The lymphatic system plays a crucial role in bolstering our immune system. It consists of a network of lymphoid organs, lymph, and lymphatic vessels that provide structural and functional support in safeguarding the body against pathogens such as viruses and bacteria.
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...

Kinetics of Drug Elimination01:17

Kinetics of Drug Elimination

4.1K
Eliminating drugs from the body is a vital process that occurs through excretion or metabolism. Understanding the kinetics of drug elimination is crucial for drug development, dosage determination, and optimizing patient outcomes.
Drug clearance depends on the rate of drug elimination and its plasma concentration. Another important parameter is the half-life of a drug, which is the time required for its concentration to decrease by half. In most cases, drug clearance follows first-order...

Area of Science:

  • Microsurgery
  • Surgical Oncology
  • Lymphedema Management

Background:

  • Immediate lymphatic reconstruction (ILR), also known as the lymphatic microsurgical preventative healing approach (LYMPHA), aims to prevent secondary lymphedema post-breast cancer treatment.
  • ILR involves intussuscepting arm lymphatic channels into a central draining vein, but its execution in deep surgical fields presents technical challenges.

Purpose of the Study:

  • To present a technical modification of ILR using a pulmonary wire to facilitate lymphatic channel intussusception.
  • To improve the ease and efficacy of performing ILR in deep surgical fields.

Main Methods:

  • A novel technique employing a pulmonary wire and mini-forceps for lymphatic channel intussusception during ILR was developed.
  • Intraoperative fluorescein isothiocyanate (FITC) imaging was used to track lymphatic flow and confirm anastomosis patency.
  • Vein grafts were harvested and anastomosed to isolated lymphatic channels and the accessory axillary vein.

Main Results:

  • The modified technique successfully facilitated lymphatic channel manipulation and intussusception in a deep surgical field.
  • FITC imaging confirmed lymphatic flow through the vein graft and across the anastomosis into the recipient vein.
  • The use of mini-forceps eliminated the need for the U-Stitch, simplifying the procedure.

Conclusions:

  • This modified ILR technique, utilizing a pulmonary wire and mini-forceps, enhances the ability to perform lymphatic channel intussusception.
  • The improved technique offers a more manageable approach to ILR, potentially increasing its adoption for lymphedema prevention.
